SYSTEMS AND METHODS FOR ASSEMBLING PREFABRICATED WALLS

TECHNOLOGICAL FIELD

The presently disclosed subject matter refers in general to the field of assembling prefabricated construction walls.

BACKGROUND

The concept of prefabrication construction is commonly known to include fabrication of a wall panel, prior to delivery to a construction site, in a factory or a workshop, and transporting the prefabricated panels to the construction site for being assembled to form the walls of a building. The wall panels are assembled and installed by the way of various anchoring systems connection the wall panels together on the top of each other and/or sideways.

The customary procedure for connecting the anchorage between the wall panels includes leaving openings in the wall panel, while manufacturing in the factory, to connect the anchoring system during assembling/installation on-site. As a result, there is a lot of on-site work that also necessitates site-inspections. One conventional solution for reducing the open surfaces on the wall opening for access points for the connections, includes using small anchors, that result in tolerance issues.

GENERAL DESCRIPTION

The presently disclosed subject matter according to the aspects detailed below is related to assembly of prefabricated walls. The prefabricated walls are constructed from horizontal and vertical beams e.g. tracks and studs, forming a frame structure and one or more layers to cover the frame from both sides. The prefabricated walls of the presently disclosed subject matter according to the aspects detailed below, include an integral resistance layer having a solid-surface exterior face. The resistance layer can be made of synthetic/man-made materials, for example, comprising one or more of the following materials: an acrylic polymer, a Methyl methacrylate (MM A), an alumina trihydrate (ATH), a polyester, epoxy, composite materials, and any combination thereof. The resistance layer can be characterized by one or more of the following: non-porous, impermeable, low-maintenance, stain resistant, thermoform-able, moisture resistant, heat resistant, fire resistant, easy to clean, anti-bacterial, hard-wearing, highly resistant, easy connectable to one other solid surface materials, and any combination thereof.

An exterior surface, i.e., the surface configured to face away from the frame, of the resistance layer is covered with a finishing layer having an interior surface facing towards the resistance layer and a factory-finished exterior surface. The factory finished exterior surface constitutes a front face and/or a back face of the prefabricated wall, i.e., the face that is configured to face the interior or exterior of the room or building. This feature of the factory-finished exterior face of the prefabricated wall allows using it ‘as is’, e.g., without requiring any further treatment and finishing after leaving the factory, such as applying coating, painting, etc.

The factory-finished exterior face can be for example, one of the following: Corian®, Avonite Surfaces®, HI-MACS®, KRION®, etc.

The prefabricated walls of the presently disclosed subject matter can be manufactured and constructed in a factory or a workshop according to specific design requirements (e.g., architectural design) and in a precise manner, for example by a CNC machine, and ready to be transported to the construction site completely closed, i.e., with the resistance layer and the finishing layer already being installed with the wall. The closed prefabricated wall can have the frame structure completely covered so as to leave almost no opening in the wall for assembling purposes, thereby leaving little work to be done on-site and requiring no inspections. The prefabricated wall can include therein internal pre-formed openings for accommodating different infrastructure, such as plumbing, piping and electrical and/or communication wiring, and it can include the infrastructure itself, for example, when leaving the factory.

According to a first aspect of the presently disclosed subject matter, there is provided a system for assembling prefabricated walls, said system comprising: at least one prefabricated wall having an anchor pathway extending therethrough along a height thereof and between a bottom opening and a top opening; a first anchoring element; a second anchoring element configured to be coupled to the first anchoring element, and to be slidingly received and extend along within the anchor pathway; and a coupler configured to couple the second anchoring element to the first anchoring element, said bottom opening being configured for slidably receiving the first anchoring element, the coupler and at least a first end of the second anchoring element coupled to the first anchoring element.

The prefabricated wall can be a closed wall with the resistance layer and the finishing layer already been applied onto the frame structure prior to be delivered on-site. The prefabricated wall can comprise a front face and an opposite back face, both the faces constituted by the exterior surface of the finishing layer and separated by a thickness of the prefabricated wall, a top face and an opposite bottom face, each extending between the front and back face and separated by a height of the prefabricated wall, two side faces opposite each other, each extending between the front and back face as well as the top and bottom face and separated by a width of the prefabricated wall.

The anchor pathway can be a bore-hole or a tunnel extending between the top face and the bottom face of the prefabricated wall, and can have a circular or a polygonal shaped cross-section. The anchor pathway can be surrounded on two sides by the vertical beams of the frame structure and the resistance layers on other two sides.

In some examples, the prefabricated wall can be in the form of a column having thickness and width substantially similar, and can have only one anchor pathway. In some examples, the prefabricated wall can have a width substantially larger than the thickness of the wall and can have two side portions separated along the width of the wall with a central portion therebetween. The two side portions can each include a respective anchor pathway. In some examples, the prefabricated wall can have more than two anchor pathways depending upon the width of the wall.

The first anchoring element can be a tension rod configured to at least partially pass through the anchor pathway. In some examples, when the prefabricated wall has more than one anchor tunnels, there can be more than one first anchoring elements corresponding to each anchor tunnel.

The second anchoring element can be a tension rod configured to be coupled to the first anchoring element via the coupler. The coupler can be a coupling nut having two internal threaded portions each configured to be threaded with a corresponding external threaded tip of the first and the second anchoring element. In some examples, a tip of one of the first and the second anchoring elements can have an internal threading and a corresponding tip of the other of the first and the second anchoring elements can have an external threading, and the two tips can constitute the coupler. The bottom opening of the anchor tunnel has dimensions so as to slidably receive the first anchoring element, the coupler, and at least the first end of the second anchoring element.

The system for assembling prefabricated walls according to the first aspect can further comprise an alignment element including a base portion with a through-opening configured to allow the first anchoring element to pass therethrough, and an aligning portion extending from the base portion configured to align the bottom opening of the anchor pathway with the alignment element. The alignment element can be configured to align the prefabricated walls in the designated positions during assembly of the walls and/or in case of lifting of the wall due to external forces like earthquakes etc.

The aligning portion can be configured to be received into the bottom opening of the anchor pathway. The aligning portion can be configured to be partially received into the bottom opening. The aligning portion can comprise at least two main aligning plates perpendicular to the base portion and extending therefrom, and having edges converging in a direction away from the base portion. The slope of the convergence of the edges can be a gradient slope, i.e., the slope can be a variable slope along the length of the edge. A maximum distance between the edges of the main aligning plates corresponds to a respective dimension of the bottom opening. The converging edges are configured to allow a rim of the bottom opening to slide thereon such that the bottom opening gets aligned with the aligning element thereby aligning the prefabricated wall with the alignment element in a first direction.

The main aligning plates can have respective internal surfaces facing each other and opposite external surfaces, wherein the aligning portion can further comprise at least one auxiliary aligning plate extending perpendicularly from the external surface of each of the main aligning plates. Each of the auxiliary aligning plates can have an edge sloped away from the external surface of the main aligning plate in a direction towards the base portion. The slope of the edge of the auxiliary aligning plate is gradient slope. A maximum distance between the edges of the auxiliary aligning plates of the two main aligning plates corresponds to a respective dimension of the bottom opening. The slope of the edges of the auxiliary aligning plates are configured to allow the rim of the bottom opening to slide thereon such that the bottom opening gets aligned with the aligning element thereby aligning the prefabricated wall with the alignment element in a second direction perpendicular to the first direction.

In some examples, the aligning portion can comprise one main aligning plate and one auxiliary aligning plate perpendicular each other and having edges converging in a direction away from the base portion so as to allow the rim of the bottom opening to slide thereon such that the bottom opening gets aligned with the aligning element thereby aligning the prefabricated wall with the alignment element.

In some examples, the aligning portion can have a dome shaped structure converging in a direction away from the base portion so as to align the bottom opening and the wall with the alignment element. In other examples, the aligning portion can have any suitable shape and structure capable of aligning the bottom opening and/or the prefabricated wall with the alignment element.

The system for assembling prefabricated walls according to the first aspect can further comprise a guiding element configured to be positioned at least partially within the anchor pathway in proximity to the top opening thereof. The guiding element can be configured to guide a second end of the second anchoring element into the top opening to pass therethrough from within the anchor pathway. The top opening can be narrower than at least a majority of the anchor pathway, and the guiding element can have a lower end portion having dimensions corresponding to those of the anchor pathway, an upper end portion configured to be positioned adjacent the top opening having dimensions corresponding to those of the top opening, and an intermediate portion extending therebetween.

In some examples, the guiding element can be integrally formed with the anchor pathway. In other examples, the guiding element can be manufactured separately of the anchor pathway.

The system for assembling prefabricated walls according to the first aspect can further comprise a locking element configured to lock the second anchoring element at the top opening. The locking element can include one or more of a lock nut, a jam nut, a washer, or combinations thereof. The locking element can include any mechanism configured to restrain the movement of the second anchoring element with respect to the top opening.

In an example, the at least one prefabricated wall can be configured to be assembled on top of a bottom prefabricated wall identical to the at least one prefabricated wall, wherein the first anchoring element is constituted by an end of another anchoring element protruding from the bottom prefabricated wall. The bottom prefabricated wall can comprise another anchor pathway and the other anchoring element can protrude from the other anchor pathway of the bottom prefabricated wall. The alignment element can be configured to be positioned at top opening of anchor pathway of the bottom prefabricated wall, and can be configured to align the at least one prefabricated wall onto the bottom prefabricated wall. The alignment element can be configured to align the anchor pathway of the at least one prefabricated wall onto the anchor pathway of the bottom prefabricated wall. The guiding element can be configured to be positioned at least partially within the anchor pathway of the bottom prefabricated wall and can be configured to guide the end of the other anchoring element constituting the first anchoring element. The alignment element and the guiding element can be integrally formed as a single element. The alignment element and the guiding element can be separately manufactured.

In another example, a second end of the second anchoring element can be configured to constitute the first anchoring element for another top prefabricated wall identical to the at least one prefabricated wall, and configured to be coupled to another anchoring element and be received in anchor pathway of said other top prefabricated wall. The alignment element can be configured to be positioned at the top opening of the anchor pathway of the at least one prefabricated wall, and can be configured to align the other top prefabricated wall onto the at least one prefabricated wall. The alignment element can be configured to align the anchor pathway of the other top prefabricated wall onto the anchor pathway of the at least one prefabricated wall. The guiding element can be configured to be positioned at least partially within the anchor pathway of the at least one prefabricated wall and is configured to guide the second end of the second anchoring element.

In yet another example, the first anchoring element can protrude from a base support element. The base support element can be a concrete base or steel beam on which the prefabricated walls are to be assembled. The first anchoring element can be connected to the base support element either by welding, bolting, or any mechanical means to attach the first anchoring element to the steel beam or by embedding it into the concrete base. The alignment element can be configured to be positioned at the base support element, and can be configured to align the at least one prefabricated wall onto the base support element.

In some examples, the first end of the second anchoring element can be coupled to the first anchoring element while the second anchoring element being completely separated from the prefabricated wall, and the prefabricated can then be lowered onto the second anchoring element while first receiving its second end into the bottom opening and then the first end, the coupler, and the first anchoring element.

In other examples, the second anchoring element can be inserted into the anchor pathway prior to the second element being coupled to the first anchoring element. The prefabricated wall can be lowered up to just above the first anchoring element and then the first end of the second anchoring element can be coupled to the first anchoring element. The prefabricated wall can then be lowered completely to rest on the base support element.

When the prefabricated wall has been completely lowered, a second end of the second anchoring element protrudes from the top opening of the anchor pathway, and can be locked by a locking element such as a lock nut, jam nut, washer, or the like.

DETAILED DESCRIPTION OF EMBODIMENTS

Reference is now made to FIGS. 1A-1E which are schematic illustrations of a prefabricated wall 10 as a part of a system for assembling prefabricated walls according to an example of the first aspect of the presently disclosed subject matter, generally designated as 1. The prefabricated wall 10 comprises a frame structure 12 having a resistance layer 14 connected to a face thereof, and a finishing layer 16 connected to an exterior surface 14A of the resistance layer 14. The resistance layer and finishing layer from another opposite face of the frame structure have been removed for illustration purposes. A factory finished exterior surface 16A of the finishing layer 16 constitutes a front face 10A of the prefabricated wall. The factory finished exterior surface of the opposite finishing layer (not shown) constitutes a back face 10B of the prefabricated wall. The prefabricated wall 10 includes two side portions 11 and 11′, a central portion 13 constituted by portions of the front face 10A and back face 10B, a bottom portion 15, and a top portion 17. The side portions 11 and 11′ include respective side faces constituting the side faces 10C and 10D of the prefabricated wall extending between the front face 10A and back face 10B. The bottom portion 15 includes a bottom face 10E of the prefabricated wall 10 and the top portion 17 includes a top face 10F of the prefabricated wall 10, such that the two side faces 10C and 10D extend together with the front face 10A and the back face 10B between the bottom face 10E and the top face 10F.

The prefabricated wall has anchor pathways 20 and 20′ extending therethrough along a height H of the prefabricated wall and each between respective top openings 20A and 20A′, formed in the top face 10F and respective bottom openings 20B and 20B′ formed in the bottom face 10E. In the illustrated example, the prefabricated wall 10 has a width W significantly longer than a thickness T thereof, and there are two anchor pathways 20 and 20′ extending through side portions 11 and 11′. The anchor pathway 20 has a first dimension D1 in a direction along the width W of the prefabricated wall 10, and a second dimension D2 in a direction along the thickness T of the prefabricated wall 10. In the illustrated example, the anchor pathway 20 has uniform dimensions D1 and D2 throughout the length of the anchor pathway 20 along the height H of the prefabricated wall 10. In other examples, the top opening 20A and the bottom opening 20B can have different dimensions than the rest of the anchor pathway. For instance, the top opening 20A and the bottom opening 20B can be narrower than the rest of the anchor pathway 20.

In some examples (not shown), the prefabricated wall can be in the form of a column having thickness and width substantially similar, and can have only one anchor pathway extending therethrough.

Reference is now made to FIGS. 2A-2E which are schematic illustrations of system 1 depicting assembling of the prefabricated wall 10. FIG. 2A shows a base support element 22 having a first anchoring element 24 with its first end 24A connected thereto. A second end 24B of the first anchoring element 24 is coupled to first end 26A of a second anchoring element 26 via a coupler 28. The coupler 28 can be a coupler nut having two threaded portions at two ends each configured to be coupled to the first and the second anchoring elements respectively. Although FIG. 2A depicts another first anchoring element 24′, another second anchoring element 26′ and another coupler 28′ with same features as those of the first anchoring element 24, second anchoring element 26 and coupler 28, only the first anchoring element 24, second anchoring element 26 and coupler 28 have been described in detailed for the purpose of clarity.

As can be seen in FIG. 2B, the system 1 further includes an alignment element 30 connected to the base support element 22 such that the first anchoring element 24 passes through a base portion 31 of the alignment element 30 and is locked at the alignment element 30 by a lock nut 27. The alignment element 30 is configured to be received into and align the bottom opening 20B and thus the prefabricated wall 10 into its exact position while it is lowered, as detailed further herein below.

FIG. 2C depicts the system 1 with the prefabricated wall 10 having been lowered onto the base support element 22 while slidingly receiving the first anchoring element 24, the first end 26A of the second anchoring element 26, and the coupler 28 within the anchor pathway 20 through the bottom opening 20B. As can be best seen in FIGS. 2D and 2E, a second end 26B of the second anchoring element 26 protrudes from the top opening 20A of the anchor pathway 20.

The system 1 includes another alignment element 30 positioned at the top opening 20A of the anchor pathway 20 such that a through-opening 31A formed in the base portion 31 of the alignment element 30 is aligned with the top opening 20A. The second end 26B of the second anchoring element 26 passes through the through-opening 31A and is locked at the top opening 20A by a locking element 25. The locking element 25 includes a washer plate 25A placed over the base portion 31 of the alignment element 30, a lock nut 25B and a jam nut 25C. The second end 26B of the second anchoring element 26 can constitute a first anchoring element for another top prefabricated wall to be received on the top of the prefabricated wall 10, and the other alignment element 30 positioned at the top opening 20A can be configured to align the bottom opening of the anchor pathway of the other top prefabricated wall. The second end 26B of the second anchoring element 26 has a guiding tip 26C removably connected thereto and configured to assist the guiding of the second end 26C through the anchor pathway 20, the top opening 20A, and the through-opening 31A.

The system 1 further includes a guiding element 40 positioned within the anchor pathway 20 in proximity to the top opening 20A. The guiding element 40 has a lower end portion 40A, an upper end portion 40B narrower than the lower end portion 40A and positioned adjacent and aligned with the top opening 20A and the through-opening 31A of the alignment element 30, and an intermediate portion 40C extending between the lower end portion 40A and the upper end portion 40B.

Reference is now made to FIGS. 3A-3C to describe in detail the structure of the alignment element 30 and guiding element 40 according to an example of the presently disclosed subject matter. FIGS. 3A and 3C illustrate the alignment element 30 and the guiding element 40 integrally formed with each, whereas FIG. 3B illustrates the alignment element 30 and the guiding element 40 having been manufactured separately and connected together. The alignment element 30 has the base portion 31 having the through-opening 31A, and an aligning portion 32 extending from the base portion 31. The aligning portion 32 includes two main aligning plates 34 extending from and perpendicular to the base portion 31. The main aligning plates 34 have edges 35 converging in a direction away from the base portion 31. The slope of the convergence is a gradient slope. In other examples, this slope can be a constant slope. A maximum distance D3 between the edges 35 of each of the main aligning plates 34 corresponds to respective dimension of the bottom opening 20B, which in the illustrated example is D1. When the prefabricated wall 10 is being lowered, or during upliftment of the prefabricated wall 10 in a seismic event, the bottom opening 20B slides on the edges 35 and gets aligned precisely over the alignment element 30 in the direction along the width W of the prefabricated wall 10. Each main aligning plate 34 has internal surface 34A, and opposite external surface 34B having auxiliary aligning plates 36 extending perpendicularly therefrom. The auxiliary aligning plate 36 has edge 37 sloped away from the main guiding plate 34 in a direction towards the base portion 31 of the aligning element 30. The slope of the edge 37 is a gradient slope. In other examples, the slope of the edge 37 can be a constant slope. A maximum distance D4 between the edges 37 of the auxiliary aligning plates 36 of the two main aligning plates 34 corresponds to respective dimension of the bottom opening 20B, which in the illustrated example is D2. When the prefabricated wall 10 is being lowered, or during upliftment of the prefabricated wall 10 in a seismic event, the bottom opening 20B slides on the edges 37 and gets aligned precisely over the alignment element 30 in the direction along the thickness T of the prefabricated wall 10.

The lower end portion 40A of the guiding element 40 has a dimension D5 along the width W of the prefabricated wall 10, that corresponds to the respective dimension of the anchor pathway 20, i.e., D1. The lower end portion 40A of the guiding element 40 has a dimension D6 along the thickness T of the prefabricated wall 10, that corresponds to the respective dimension of the anchor pathway 20, i.e., D2. As can be seen the best in FIG. 3C, the upper end portion 40B of the guiding element 40 has dimensions that corresponds to those of the through-opening 31A of the alignment element 30. In examples where the top opening 20A is narrower than rest of the anchor pathway 20, the dimensions of the upper end portion 40B of the guiding element 40 corresponds to those of the top opening 20A. While the prefabricated wall 10 is being lowered, the dimensions of the guiding element 40 causes the guiding element 40 to guide the second end 26B of the second anchoring element 26 through the top opening 20A and the through-opening 31A of the alignment element 30.

FIG. 3D illustrates an alignment element 30′ according to another example of the presently disclosed subject matter. The alignment element comprises a base portion 31′ having a through-opening 31A′, and an aligning portion 32′ extending from the base portion 31′. The aligning portion 32′ has a bottom end 32A′ connected to the base portion 31′ and having a dimension D7 to be positioned along the width W of the prefabricated wall that corresponds to the respective dimension of the anchor pathway 20, i.e., D1. The bottom end 32A′ has a dimension D8 to be positioned along the thickness T of the prefabricated wall that corresponds to the respective dimension of the anchor pathway 20, i.e., D2. The aligning portion 32′ converges in a direction away from the base portion 31′ such that a top end 32B′ thereof is narrower than the bottom end 32A′. The slope of the convergence is gradient slope. In other examples, the slope can be a constant slope. When the prefabricated wall 10 is lowered, the slope of the aligning portion causes the bottom opening 20B to be aligned precisely with the alignment element 31′. The top end 32B′ has a through-opening 31B′ configured to allow the first anchoring element 24 and/or the second anchoring element 26 to pass therethrough.

FIG. 4A schematically illustrates a sequence of assembling the prefabricated wall 10, according to an example of the presently disclosed subject matter. As shown in FIG. 4A, first of all the first anchoring elements 24 are connected to the base support element 22 followed by coupling the second anchoring elements 26 thereto via the couplers 28. After installing the first and the second anchoring element, the prefabricated wall 10 is lowered onto the base support element 22 while receiving the second end 26B of the second anchoring element 26, the coupler 28 and the first anchoring element 24 into the anchor pathway 20 via the bottom opening 20B. Then the second end 26B of the second anchoring element 26 is locked at the top opening 20A by the locking element 25.

FIG. 4B schematically illustrates a sequence of assembling the prefabricated wall 10, according to another example of the presently disclosed subject matter. As shown in FIG. 4B, first of all the first anchoring elements 24 are connected to the base support element 22. The second anchoring element 26 with the coupler 28 connected to the first end 26A thereof is inserted into the anchor pathway 20. Then the prefabricated wall 10 is lowered up to just above the first anchoring element 24, and the second anchoring element 26 is lowered so as to be coupled to the first anchoring element 24. After coupling the second anchoring element 26 and the first anchoring element 24, the prefabricated wall 10 is completely lowered onto the base support element 22. Then the second end 26B of the second anchoring element 26 is locked at the top opening 20A by the locking element 25. As shown in FIG. 4C, the second anchoring element 26 can be lowered and coupled to the first anchoring element 24 by a special tool 45 connected to the second end 26B of the second anchoring element 26. The tool 45 can be used to thread the second anchoring element 26 with the first anchoring element 24 via the coupler 28, and then can be disconnected from the second anchoring element 26. The tool 45 has a safety cable 45A configured to secure the tool 45 to the prefabricated wall 10 during operation thereof.

In some examples of any of the alternative sequences, an alignment element (not shown) can be positioned at the base support element 22 after connecting the first anchoring element 24 and prior to coupling the second anchoring element 26 thereto. In some examples of any of the alternative sequences, a guiding element (not shown) can be positioned in the anchor pathway 20 in proximity to the top opening 20A prior to lowering the prefabricated wall 10. In some examples of any of the alternative sequences, an alignment element (not shown) can be positioned at the top opening 20A either prior to or after lowering the prefabricated wall 10, but prior to locking the second end 26B.

Although the above description has been provided with reference to one prefabricated wall 10, it is to be understood that in the similar manner, more prefabricated walls can be assembled one above other, and the above description applies to such an assembly. The prefabricated wall 10 can be the bottom most wall of the whole assembly, a middle wall, or can be a top wall configured to be assembled in the similar manner on the top of a bottom prefabricated wall. The first anchoring element and the alignment element for the bottom most wall is connected to the base support element. The second end of second anchoring element of every bottom wall constitutes a first anchoring element for its top wall. The alignment element positioned on top of every bottom wall constitutes the anchoring element for aligning its top wall. All the prefabricated walls have to be identical at least in the manner to have the anchor pathways similar to the anchor pathway 20 described above.

Reference is now made again to FIGS. 1A-1E for describing the system 1 according to the second aspect of the presently disclosed subject matter. The system 1 further comprises a first engaging member 60 connected to a side face 10D of the prefabricated wall 10. The first engaging member 60 includes three protrusions 60A, 60B, and 60C extending from the side face 10D. The protrusions 60A-C can be integrally formed with the frame structure 12 or can be separately manufactured and mounted to the frame structure 12. In some examples, the first engaging member 60 can be just one protrusion extending along the height H of the prefabricated wall 10. Each of the protrusions 60A-60C has respective protrusion tops 62A-62C and two protrusion sides 64A-64C and 64A′-64C′ extending between the prefabricated wall 10 and the protrusion tops 62A-62C.
