The present invention is in the field of construction blocks, in particular, modular blocks which are configured for quick assembly during a construction process.
A Structural insulated panel (or structural insulating panel), SIP, are a composite building material. They consist of an insulating layer of rigid core sandwiched between two layers of structural board. The board can be sheet metal, plywood, cement, magnesium oxide board (MgO) or oriented strand board (OSB) and the core either expanded polystyrene foam (EPS), extruded polystyrene foam (XPS), polyisocyanurate foam, polyurethane foam or composite honeycomb (HSC).
SIPs share the same structural properties as an I-beam or I-column. The rigid insulation core of the SIP acts as a web, while the sheathing fulfills the function of the flanges. SIPs combine several components of conventional building, such as studs and joists, insulation, vapor barrier and air barrier. They can be used for many different applications, such as exterior wall, roof, floor and foundation systems.
It is common to use SIP to construct walls during conventional building. There are various ways of constructing a wall structure using insulated panels and method for connecting panels to one another.

Acknowledgement of the above references herein is not to be inferred as meaning that these are in any way relevant to the patentability of the presently disclosed subject matter.
According to a first aspect of the subject matter of the present application there is provided a construction block comprising:
wherein at least a portion of the external segment of the frame arrangement is contained within one of the first and second panels.
The term ‘conterminous with’ should be broadly understood in the context of the present application as being such that one or more of the panels has a portion thereof which is set against at least one of the corresponding surfaces of the support member, regardless of the manner at which the panels are held in place. Specifically, the panels can be attached, fitted, adhered, cast or molded to the two or more support members.
Each of said support members can be in the form of a sheet structure or profile, i.e. made of a sheet which was formed or folded to assume the shape of the support member. In particular, the sheet structure can be made of a material chosen such that can properly support the weight of the first and second panel, when formed thereon. Specifically, the structure can be a sheet-metal structure, and in accordance with a specific example, be made of steel.
The hollow can extend the entire length of the support member and have a first opening at a top portion of the support member and a second opening at a bottom portion of the support member. As will be further discussed, since the construction block can be used in the construction of a wall structure, having both a top and a bottom opening for the hollow can allow a more versatile assembly and arrangement of different constructions blocks to one another.
In addition, at least one of the two or more support members can comprise a first side wall with a first side opening and a second side wall opposite the first side wall, with a second side opening, defining a cross-channel between the first and the second side wall. The cross-channel can be configured for passing therethrough of piping and/or wiring within the construction block. The arrangement can be such that said cross-channel is not obstructed by the first and the second panel, extending in a direction transverse thereto.
The frame arrangement can be made of a rigid material configured for holding the support members in fixed relation with respect to one another. In accordance with a specific example, the frame arrangement can be made of metal. The frame arrangement can be fixedly attached to the two or more support members in a variety of ways, for example, by welding.
The two or more support members can be spaced apart, so that the construction block comprises at least one internal cavity defined between the support members, thereby reducing the overall density and weight of the construction block (as compared to that of a construction block which is filled solid.
In accordance with a particular example, the first faces of the two or more support members can be oriented flush with respect to each other and the second faces of the two or more support members can also be oriented flush with respect to each other, respectively defining a first mating plane and a second mating plane.
According to a specific design of the construction block, any one of the following features may apply:
In a construction block comprising more than two support members arranged along a longitudinal dimension of the construction block, a support member having one or more neighboring support members on both sides thereof (along the longitudinal dimension) can be defined as an intermediate support member and a support member which has one or more neighboring support members on only one side thereof (along the longitudinal dimension), can be defined as an end support member.
The pin slot or securing pin can be formed at an external side wall of an end support member, so that when two construction blocks are arranged side-by-side, the securing pin of one of the two support members is configured for being received within a pin slot of the other of the two support members.
According to one example, the construction block can comprise four support members arranged such that the two of the four support members are spaced apart from one another defining a space, and serving as end support members, and the other two support members are disposed within in said space. The other two support members can be conjoined, forming a single unit, which may be centrally disposed within said space between the first two end support members.
The shape of the construction block is not limited to a longitudinal block and can assume an L-shaped design, comprising two end support members, each disposed at a different end point of the L-shape, and a third, intermediate support member disposed at the corner of the L-shape. The construction block can also assume other shapes and designs, for example, a T-shape comprising three end support members, each disposed at a different end point of the T-shape, and one intermediate support member disposed at the intersection of the T-shape.
In accordance with a particular example, said construction block can comprise a plurality of support members including a first end support member and a second end support member spaced apart from one another to define a space, and a plurality of support member pairs, each comprising two conjoined support members, disposed sequentially in said space.
In accordance with another aspect of the subject matter of the present application, there is provided a wall structure comprising two or more construction blocks according to the previous aspect of the application, said wall structure further comprising at least one tenon element having a first portion thereof received in a hollow of one of the two or more support members of a first of the two or more construction blocks and a second portion thereof received in a hollow of one or more of the two support members of a second of the two or more construction blocks, thereby holding them together.
The construction blocks can be arranged without offset such that the first portion of the tenon is received within a hollow of a first support member of a first of the two or more construction blocks through a top opening thereof and a second portion thereof is received in a hollow of a corresponding first support member of a second of the two or more construction blocks through a bottom opening thereof, thereby holding them together. Alternatively, the construction blocks can be arranged at an offset with respect to one another, such that the first portion of the tenon is received within a hollow of a first support member of a first of the two or more construction blocks through a top opening thereof, and a second portion thereof received in a hollow of a support member of a second of the two or more construction blocks different than the first support member thereof, through a bottom opening thereof.
In accordance with one example, said wall structure can further comprise a securing pin having a first portion thereof received within a pin slot of a support member of a first of the two or more construction blocks and a second portion thereof received in a pin slot of a support member of a second of the two or more construction blocks, thereby preventing detachment between the first block and the second block.
In accordance with another example, as mentioned above, each construction block can comprise a pin slot at one of the end support members thereof and a securing pin at the other of the end support members so that when two construction blocks are aligned side-by-side, the securing pin of one construction block fits into the pin slot of the neighboring construction block.
The wall structure can further comprise a ground base configured for positioning thereon a first row of construction blocks, said base comprising a longitudinal plate formed with one or more base tenon elements disposed therealong and configured for being received within corresponding hollows of the support members through a bottom opening thereof.
In addition, the wall structure can comprise a top closure piece configured for being mounted over a top row of construction blocks to cover a top portion thereof, including the top openings of the hollows of the support members thereof.
It is appreciated that when a plurality of such construction blocks are arranged to form a wall structure, and specifically, when they are arranged one on top of the other, regardless if they are aligned or at an offset with respect to one another, the hollows of the support members form continuous longitudinal support channels extending transverse to the longitudinal dimension of the construction blocks (for a vertical wall structure, these channels will extend vertically). A plurality of tenon elements can be received within each such support channel, each tenon bridging between two neighboring construction blocks, and resting on the vertically neighboring tenon position below it. Under such a construction, the tenon elements serve together as a load-bearing support pillar for the entire wall structure.
It is appreciated, however, that for a wall structure comprising a plurality of construction blocks as described above, the arrangement can be such that not each of the support channels has to receive and contain tenon elements therein. In particular, for construction blocks which support channels are not filled with tenon elements, the securing pins (and their insertion into corresponding pin slots) can provide a solution for fixing the construction blocks to one another.
In accordance with another aspect of the subject matter of the present application, there is provided a method for the assembly of a wall structure according to the previous aspect, said method comprising the steps of:
The method can also include the step of inserting a securing pin into the wall structure so that a first portion thereof is received within a pin slot of a support member of the first of the two or more construction blocks and a second portion thereof is received within a pin slot of a support member of the second of the two or more construction blocks. Alternatively, the step placing, when two construction blocks are positioned side-by-side, the second of the two or more construction blocks so that a securing pin on one end thereof is received within a pin slot of a corresponding end of the first of the two or more constructions blocks.
The method can further include a preliminary step of:
The method can also comprise the step of positioning a top closure piece over a top of a topmost construction block to cover a top portion thereof, including the top openings of the hollows of the support members thereof.
In order to better understand the subject matter that is disclosed herein and to exemplify how it may be carried out in practice, embodiments will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in which:
Attention is first drawn to
As observed from
With further attention being drawn to
The right-most end support member 20 also comprises a securing pin 90 extending vertically along the outside side surface 22S of the support member 20, and the left-most end support member 20 comprises a securing port 28B extending vertically through side surface 22S of the support member 20, and configured for receiving therein the securing pin 90.
The four support members 20 are fixedly attached to each other by a support frame 40, made of several metal struts 42, and connected to the support members 20 via welding of extensions 44 thereof. It is noted that the support frame 40 extends outside the boundary of the support members 20, the purpose of which will be discussed in detail with respect to
With additional reference being made to
The arrangement is such that the external side 22S of the right-end support member 20 is flush against the inner surface of the right-side wall SWR of the mold M and the external side 22S of the left-end support member 20 is flush against the inner surface of the left-side wall SWL of the mold M. The front face 22F and the rear face 22R of the support members 20 are spaced at a gap distance G from the respective front wall FW and rear wall RW of the mold M. It is noted that the front wall FW and the rear wall RW of the mold M are also spaced at a gap distance g<G from the struts 42 of the support frame 40.
Thereafter, two rectangular filler blocks F are placed within the two main cavities 3 between the end support members 20 and the intermediate support members 20, and the mold is then filled with a foam material according to the required properties of the panels 60. As a result, the foam material fills the entire gap distance G between the support members and the respective front and rear walls FW, RW, embedding therein the support frame 40.
Once the foam material hardens, the mold M and filler blocks F can be removed (leaving therein the two main cavities 3), yielding the basic construction block 1, a cross-section of which is shown in
Furthermore, the embedding of the support frame 40 within the panels 60 eliminates the need to use external fitting means such as bolts, screws, rods etc. in order to attach ready-made foam panel to a support structure, thereby simplifying the process and allowing more versatile design of the construction blocks 1.
With reference being made to
Construction block 1′ is a half-length block, comprising only a right-end and a left-end support members 20′, construction block 1″ is an L-shaped construction block which further comprises a square shaped support member 20″, and construction block 1′″ is a T-shaped construction block.
It is appreciated that since the construction blocks 1, 1′, 1″ and 1′″ are not formed as a support structure onto which ready-made panels are mounted, the support structures 10, 10′, 10″, and 10′″ can be placed within a proper corresponding mold M, M′, M″, M′″ (chosen according to the final shape and dimensions of the construction block) and provide the suggested designs.
Turning now to
The base plate 100 is in the form of a flat panel 102 comprising slots 104 configured for allowing fastening of the panel 102 to a base surface such as a floor or ground. The panel 102 is formed with at least one base tenon 110 comprising a body 112 projecting from the panel 102 and two flange portions 114 affixed to the panel 102 by fastening means 116 (shown
With additional reference being made to
Therafter, linking tenon elements 140 are placed in the cavities accommodating the base tenon elements 110. Each linking tenon 140 is equal in length to the height of the support member 20, so that when it is placed within the respective cavity 24, half its length is accommodated within the cavity 24 (the other half being occupied by the base tenon 110), and the other half projects vertically to receive the following construction block 1.
In this manner, an entire wall structure can be construction in a lego-like manner. One of the advantages of such an easy and modular construction lies in the fact that no support or load-bearing pillars are required. Specifically, once a set of cavities of support members 20 of different construction blocks 1 are vertically aligned, and completely filled with linking tenon elements 140, those tenon elements then constitute a vertical load bearing pillar of the wall structure. Further explanations regarding this matter will be provided with respect to

In essence, the lintel 200 is similar in design to the block 1′ shown in
The length of the lintel 200 is chosen according to the gap of the opening it is required to bridge, and specifically, so that, when placed over the opening as shown in
In this manner, when being placed over the top end of the opening, bottom openings of the support members 220 of the lintel 200 can received therein the top portion of the tenon elements 140R which projects from the construction blocks 10 which are located at the level of the opening.
With particular reference being made to
Using the lintel 300 allows for several advantages, some of which are:
Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations, and modifications can be made without departing from the scope of the invention, mutatis mutandis.
