The present invention relates to a functional system for a cement mortar panel with prestressed biaxial reinforcement. In the invention, a system is understood to be an ensemble of items which, when related together in an ordered fashion, contribute to the general good quality of the said panel. On the other hand, functional is understood to be all that relating to the design or organization of the system which pursues the ease, utility and convenience of its use.
To be precise it consists of a system of things of substance, namely, of elements contributing to the functionality of the system, to the physical, formal and functional constitution of the ensemble, allowing it to be handled and used under maximum safety and efficiency conditions, in its application to a panel of the type prefabricated with cement mortar. In building construction, the panel is for closing the openings in a building structure, both the external openings, in which case it has the visible face decorated to form the façade, and the internal openings, in which case they do not need any decoration on the visible face thereof, which delimit the patios of a building. The panel is formed by a cement mortar panel which, having a thickness of from 2 to 7 cms, includes a prestressed biaxial reinforcement which is formed by two series of prestressed cables or rods, those of one same series being mutually parallel and equidistant, while the series cross each other orthogonally without being fixedly attached to one another to form a reinforcement grid.
The present applicant is the holder of international patent application PCT/ES2007/000706, published under number WO 2008/139003, relating to a prefabricated cement mortar panel with biaxial reinforcement comprising variants of elements of a functional system which are compatible with or replaceable by new elements having like functional or innovative features.
In the above-mentioned international patent application, there were not included in the functional system thereof certain aspects or elements which make the cement mortar panel to which they are directed have improved comfort conditions, at the same time as they enhance the stability and safety features thereof.
Without belittling the qualities of the said functional system, the solution has been adopted of configuring some of the elements of the previous system, such as the versatile operating means, such that they become more neutral in their effects on the outside of the panel and more resistant to climatic conditions, the suspension means to the structure of a building provided with means controlling seismic phenomena and the settling movements of the building and the means of reducing damp inside the building.
In accordance with the foregoing solution, the functional system object of the present invention has been developed, consisting essentially in the cement mortar panel having embedded in the mass thereof versatile operating means on the panel ensemble allowing it to be handled and/or attached to suspension means to the structure of a building, to means controlling seismic phenomena and the settling movements of the building, to means for reducing damp inside the building and to means reducing the infiltration of damp inside the panel.
A feature of the invention is that the versatile operating means on the panel ensemble, allowing it to be handled and/or attached to suspension means to the structure of a building, is constituted by an oblong body formed by a thick flat bar which, in omega shape, forms a central rectangular arch which is flanked by two lateral arms, which are symmetrical relative to said central rectangular arch and mutually coplanar and form the main retaining means of the body within the mortar, the central portion of the central rectangular arch having a threaded through hole for the sequential insertion of the handling means and the anchoring means and a dimension of the ensemble such as to allow said lateral arms to be able to be located in the medial internal region of the panel in which the biaxial reinforcement is located.
A further feature of the invention, appropriate for a metallic structure formed by vertical upright profiles and horizontal cross-member profiles, and which has the purpose of facilitating the suspension of architectural panels in buildings having a reinforced concrete structure, consists of disposing a plurality of clamps provided with stable fixing means to the edges of the floor structure slabs of a reinforced concrete structure, the clamps being disposed individually in vertical alignment in said edges to form coaxially vertical guide rows for housing and retaining the upright profiles which are connected together by cross members on which the suspension means provided on the backs of the architectural panels are seated and attached.
Further features related to the above, specify that, in one case, the clamps are formed by a quadrangular bushing or ring having coplanar to one of the faces thereof two lugs, which configure it in a bridge-like fashion, as fixing means of the bushing to the edge of the floor structure slab, in a position appropriate for the vertical passage of the upright profiles, with the lugs including means for anchoring the bushing to the edge of the building floor structure slab. At the same time, the front face of the bushing, which is opposite to the seating surface of the bushing on the floor structure slab edge, has a vertical elongated hole. In another case, the clamps are formed by a folded bar portion which, forming a rectangular arch, extends orthogonally at both free ends thereof in two symmetrical coplanar lugs forming the horizontal fixing means of the bushing to the edge of the building floor structure slab.
A further feature of the invention, applicable to the case in which the versatile operating means on the panel ensemble allowing the handling and/or fixing thereof to suspension means to the structure of a building are formed by plugs formed by short, thick bodies. Thereby, the lateral region of the short, thick body, comprised between the retaining means and the anchoring means having an end region flush with the surface of the hidden face of the panel, has the side region thereof provided with irregularities increasing the surface area thereof and the distance to be covered thereover by any damp which may infiltrate in the space which may have formed between said body and the cement mortar of the panel in which it is inserted as a result of thermal expansion and/or contraction.
Further features of the invention associated with the foregoing consist of:
1.—The short, thick body basically has a configuration in the lateral region thereof of the group formed by conical surfaces, cylindrical surfaces, oval surfaces and prismatic surfaces.
2.—The surface irregularities in the lateral region of the short, thick body of the plugs are formed by reliefs projecting from the surface of said lateral region.
3.—The surface irregularities in the lateral region of the short, thick body of the plugs are formed by recesses below the surface of said lateral region.
4.—The projecting reliefs of the surface irregularities on the lateral region of the short, thick body of the plugs have an annular configuration and are contained in mutually parallel planes perpendicular to the axis of the short, thick body of the plug.
5.—The projecting reliefs of the surface irregularities on the lateral region of the short, thick body of the plugs follow helical paths with a direction of minimum damp flow.
6.—The external contact line between the plug and the cement mortar may be covered and closed with a washer including a sealing joint arrangement.
A further feature of the invention, which is particularly applicable to a wall for buildings having ecological features, the façades whereof are of the type preferably formed by prefabricated cement mortar panels having a thickness of about 3 cms which are attached to a completely metallic independent structure or a metallic structure associated with a reinforced concrete structure and which form between said panels and metallic structure a ventilated chamber, are defined by the fact that the façade support structure, be it metallic or mixed, is completely covered by a breathable sheet on the front surface thereof, which is the one comprised inside the ventilated chamber and facing the back of the prefabricated façade panels forming said ventilated chamber, said sheet being breathable only with respect to the air and damp inside the building and is breathable exclusively in one sole direction from the inside of the building towards the ventilated chamber.
Further features of the invention which are intimately related with each other and/or with the foregoing feature, are:
1.—On the rear surface of the support structure, which is the one opposite the front surface thereof containing the breathable sheet, there is abutted a water-repellent breathable board, the board being provided with a layer of foam mortar, also breathable, projected on said abutment surface towards said rear surface of the structure.
2.—A water-repellent board, having one of the faces thereof covered with a projected layer of foam mortar, is abutted by this covered face against the rear surface of the support structure, being the rear surface the one opposite the front surface which is covered by the breathable sheet.
3.—On the face of the water-repellent board not having the layer of foam mortar, there is abutted a frame which, formed by two horizontal “U”-shaped profiles and two vertical “C”-shaped profiles, houses a blanket of insulating material and which is optionally provided in the uprights thereof with holes for the passage of cables and pipes.
4.—Abutting the face of the “U” and “C”-shaped metal profile frame opposite to the face abutting the water-repellent breathable board, there is an assembly of two plasterboards abutted face-to-face of which the board closer to the building interior is covered with a layer of breathable paint.
5.—The blanket of insulating material consists of a self-supporting semi-rigid material which is disposed between the water-repellent breathable board and the assembly of plasterboards, possibly without the support of the metal profile frame.
6.—The breathable foam mortar is reinforced by materials of the group formed by cellulose fibers, rock wool, fiberglass and synthetic fibers.
A further feature of the invention is to be found in the fact that an anti-seismic device, which is specially applicable where the prefabricated panels closing the structure of a building are placed against the structure by means of a plurality of fixing members formed by a threaded rod which engages, at one end, in the threaded through hole of a versatile plug embedded in the panel and is attached thereto by a nut, at the same time as, at the other end thereof, there is fixedly attached thereto by nuts and locknuts, a polygonal seating plate which engages at one edge thereof a channel of a support profile fixedly attached to the building structure, consists of locking means which releasably stabilize the seating of the polygonal plate in the channel of the support profile fixedly attached to the building structure.
Further features of the invention forming embodiments and details thereof are described below:
1.—The locking means are formed by a retaining profile which being releasably fixedly attached in overhanging fashion to the building structure, has at the free end thereof a resiliently flexible inverted channel for engaging one side of the polygonal seating plate, opposite to the side with which it is seated in the channel of the support profile, fixedly attached to the building structure to stabilize the seating of said polygonal plate.
2.—The polygonal plate has abutting the face thereof facing the support structure and suspended on the upper edge of the polygonal plate astride this edge, locking means formed by a metal plate piece having, in the centre thereof, a window through which there freely extends the fixing locknut of said polygonal seating plate and a lower end which is bent into a perpendicular tab. The polygonal tab seats, on the one hand, on the upper face of a horizontal portion of the angular support profile fixedly attached to the structure and, on the other hand, is fixedly attached through said horizontal portion of the angular support profile to a rigidifying profile for the latter which is snugly fitted between the channel of said angular support profile and a vertical portion thereof fixedly attached to the support structure.
3.—The window of the metal sheet piece has dimensions such as to allow the positional fixing locknut of the polygonal seating plate to project therethrough and the rotation of the locknut when handling it to fix the position of said polygonal seating plate.
4.—The rigidifying profile has a rectangular rightangled tubular configuration and has a length such that allows an indefinite length of the angular support profile of the group comprising the whole of said length or a plurality of regularly spaced apart independent portions thereof to be occupied.
To facilitate the understanding of the foregoing ideas, at the same time as various details of a constructive nature are disclosed, there is described hereinbelow an embodiment of the present invention, with reference to the drawings accompanying this specification. In view of their primordially illustrative nature, these drawings must be understood to be lacking in any limiting scope relative to the breadth of the legal protection requested. In the drawings:
As shown in
The figures show that the oblong body is formed by a flat bar, preferably of ferric material such as steel, without excluding other materials. The flat bar may be shaped by a series of die-stamping and pressing operations, without excluding in any case the possibility of forming it by lost-wax casting or other process.
In the majority of cases, the oblong body consists of a single solid piece having the convex and concave transverse edges 115 thereof rounded.
This handling means 108 for the panel 102 is formed by a steel rod 116 having one end 117 threaded, which may be releasably engaged in the threaded through hole 114 provided in the central portion 113 of the central rectangular arch 111 of the versatile plug 100. At the other end, the handling means 108 is provided with a throat 118 which, as shown in
As shown in
The cross-members 131, for supporting the outwardly projecting suspension means 137, in one case, may adopt a double angle configuration or, in other cases, as shown in
The same
This sheet 150 is mounted on the floor structure slab 149 with an upper edge region 150A overlapping the floor 149 and allowing the rest of the sheet 150 to hang, covering a central portion 150B of the edge of the floor structure slab 149, while another lower edge region 150C is left suspended. The said upper edge portion 150A serves as seat for a lower horizontal metal profile 151, which is called lower relative to the opening of an upper floor, which is installed with a slight overhang relative to the edge of the floor structure slab 149 and is fixed thereto by a screw. The lower horizontal metal profile 151 is complemented in coplanar fashion by an upper horizontal metal profile 152, which is called upper relative to the opening of a lower floor. At the same time the lower edge region 150C of the sheet 150 covers the side of the upper horizontal metal profile 152, located on the lower face of the same floor structure slab 149.
The lower 151 and upper 152 horizontal metal profiles, located in one same opening between two successive floor structure slabs 149, are for supporting upright metal profiles 153 and, as “U” shaped profiles, have, respectively, base walls 151A and 152A and side portions 151B and 152B.
As shown in
The external line 179 of contact between the plug 157, 171 and 175 and the cement mortar of the panel 160 may be covered and closed with a resilient washer 180 forming a sealing gasket arrangement.
It is not excluded that some reliefs projecting from the side surface may be combined with others which do not. Likewise, it is not excluded that the short, thick body 158, 173, 177 in all cases may have basically a configuration in the side region thereof of the group comprising tapered surfaces, cylindrical surfaces, oval surfaces and prismatic surfaces.
The support structure 182 of the façade, be it metallic or mixed, has the front surface thereof, which is comprised inside the ventilated chamber 184 and facing the back of the prefabricated façade panels 181 with which said ventilated chamber 184 is formed, covered by a breathable sheet 185. The sheet 185 is breathable only with respect to the air and damp of the building interior and exclusively one way from the interior of the building to the ventilated chamber 184.
In the case of a mixed support structure 182, such as the one shown in the figures and in greater detail in
A water-repellent breathable board 188 is abutted to the rear surface of the metallic support structure 182, which is the surface opposite the one bearing the breathable sheet 185. The board 188 is provided with a layer of foam mortar 189 which is also breathable, projected on said abutment face towards the metallic support structure 182.
The water-repellent breathable board 188, which abuts the metallic support structure 182 with the face having the projected layer of foam mortar 189, also abuts with the other face thereof a support frame 190 of “C” shaped metal profiles 191. The support frame 190 holds inside, parallel to said water-repellent board 188, a blanket 192 of an insulating material which being made from a self-supporting semirigid material, allows the possibility of not having the support provided by said support frame 190.
Thereafter, abutting the face of said support frame 190 of “C” shaped metal profiles 191, opposite the one against which the water-repellent breathable board 188 is placed, there is disposed an assembly of two plaster boards 193 and 194 abutting each other, among which, the board 194, which is the one closer to the interior of the building, being covered with a layer of breathable paint 195.
The breathable foam mortar 189 is reinforced with materials of the group formed by cellulose fibers, rock wool, fiberglass and synthetic fibers.
As shown in
Up to here there has been described the application of the object of Utility Model n° ES 1 068 863, to which there is added hereinafter the description of the object of the invention. As indicated above, the object consists of disposing locking means 212 which removably resiliently and flexibly stabilizes the seating of the polygonal seating plate 209 in the channel 210 of the support profile 211 fixedly attached to the building structure 197.
The said locking means 212 consists of a retaining profile 213 which is removably fixedly attached in cantilever fashion to the building structure 197. In conditions of resilience and flexibility the retaining profile 213 has, at the free end thereof, an inverted channel 214 for engaging one side of the polygonal seating plate 209. This side is opposite the side with which it is seated in the channel 210 of the support profile 211 fixedly attached to the building structure 197.
Under these assembly conditions of the panels 196 and 196A, the arrangement of the support 211 and retaining 213 profiles in cantilever fashion confers on the installation thereof adequate resilience and flexibility to allow slight movements of the panels 196 and 196A without harming the stability of the panels 196 and 196A in the building structure 197.
Obviously, the fixing of the support 211 and retaining 213 profiles to the structure 197 by screws 215 allows the installation to be readily recomposed in case of deterioration of any of the panels or remodeled for needs of space or appearance, without excluding, thereby, that such profiles may be replaced by other members of like functionality.
Likewise, the polygonal seating plate 209, which will preferably have a rectangular or square shape, may adopt other configurations, without excluding in an extreme case the circular configuration understood as polygonal of an infinite number of sides.
Also, the versatile plugs may be of a configuration other than the one described, provided always that they have a threaded hole for the insertion of the threaded rod 200 or have an equivalent member.
As shown in
Also up to here there has been described the way in which a fixing point of a panel 216 was installed in the building 197 up to date. Hereinafter there will be described the object of the invention consisting of disposing locking means 226 which, removably, rigidly stabilizes the seating of the polygonal seating plate 223 in the channel 224 of the angular support profile 225 fixedly attached to the building structure 197.
According to the device of the invention, the polygonal seating plate 223 is provided with locking means 226 abutting the face A thereof, which is the surface facing the support structure of the building 197, and suspended from the upper edge B of the polygonal seating plate 223, riding thereon. The locking means 226 consists of a metal sheet piece 227 provided in the centre thereof with a window 228 through which there freely projects the locknut 222 for fixing said polygonal seating plate 223 and with a lower end which is bent perpendicularly to form a tab 229. The tab 229, on the one hand, seats on the upper surface of a horizontal portion 230 of the angular support profile 225 fixedly attached to the building structure 197 and, on the other hand, is fixedly attached by a screw 231 or other means, through said horizontal portion 230 of the angular support profile 225 to a rigidifying profile 232 for the latter. The rigidifying profile 232 is located in fitted fashion between the channel 224 of said angular support profile 225 and a vertical portion 233 thereof fixedly attached to the building structure.
As shown in
It should be pointed out that the rigidifying profile 232 is of right rectangular tubular configuration and of an indefinite length such as to allow a length of the angular support profile 225 of the group formed by the whole of said length or a plurality of independent portions thereof which are regularly spaced apart to be occupied. Likewise, another type of profile could be used, and even tabs die punched out from the angular support profile 225 itself which were disposed perpendicularly just below the horizontal portion 230 including on the wall of the channel 224.
