Description

[0001] This invention concerns a partition panel intended to be used in the construction of buildings and particularly in livestock buildings, restrooms, service rooms or small-scale production areas.

[0002] These types of panels allow the rapid erection of building dividers. Some of these panels comprise a bearing structure making it possible to support the load when they are used as a bearing partition; they also have thermal and/or sound insulation properties.

[0003] A classic construction example of a panel having these features consists of a bearing structure whose main faces are covered with an insulating material that needs to be attached to the bearing structure via mechanical means, clips, for example.

[0004] These types of panels, aside from their thickness and their consequent weight, have the disadvantage of allowing the transfer of heat via thermal bridge between its two main faces.

[0005] The purpose of this invention is therefore to propose a partition panel intended for use in the construction of buildings that makes it possible to eliminate the transfer of heat via thermal bridge between its two main faces.

[0006] To this end, the partition panel according to the invention intended to be used in building construction, the partition panel comprising a bearing structure and means of thermal insulation, is remarkable in that the bearing structure consists of a frame equipped with at least one opening, the means of thermal insulation being, on the one hand, positioned to cover at least one of the main faces of the bearing structure and, on the other, positioned respectively in the opening, the means of insulation being assembled by gluing.

[0007] Thus the transfer of heat by thermal bridge between the two main faces of the partition panel is greatly reduced.

[0008] According to another feature of the invention, the means of thermal insulation consist of at least one panel capable of covering respectively said main face, the panel being equipped with at least one protuberance intended to be housed in said opening.

[0009] According to another feature of the invention, the partition panel also comprises cover plates intended to cover the external face of the panel or panels and/or a main face of the bearing structure, the cover plates being assembled by gluing.

[0010] According to another feature of the invention, the material of the cover plates is chosen from laminated panels, panels made of galvanized steel plate, varnished sheet metal, stainless steel, PVC, plywood or cellulosic plates.

[0011] According to another feature of the invention, it has assembly means arranged in a median plane of the bearing structure, the means of assembly allowing the assembly of two juxtaposed partition panels.

[0012] According to another feature of the invention, the means of assembly consist, on the one hand, of bolts mounted respectively in recesses made in the upper end field of said partition panel and, on the other hand, of a flange intended to be attached to the bolts of two juxtaposed partition panels.

[0013] According to another feature of the invention, the lateral fields of the bearing structure of the partition panel are equipped respectively with complementary positioning means allowing the positioning of two partition panels in the same plane when they are juxtaposed.

[0014] According to another feature of the invention, the positioning means consist respectively of a tenon and a mortise.

[0015] According to another feature of the invention, the bearing structure is made of reinforced concrete.

[0016] According to another feature of the invention, the means of thermal insulation are made of a material selected from expanded polystyrene, extruded polystyrene or polyurethane.

[0017] A method for manufacturing this type of panel is also covered by the invention.

[0018] The method of the invention consists in producing the structure via reinforced concrete molding so that it forms a frame equipped with at least one opening, in producing the thermal insulation means so that they are able to form, on the one hand, a panel capable of covering at least one of the main faces of the bearing structure and, on the other hand, at least one protuberance intended to be housed in said opening, and in gluing the means of thermal insulation to the bearing structure.

[0019] According to another feature of the invention, the method consists in producing the means of thermal insulation by cutting out panels of material.

[0020] According to another feature of the invention, the method consists in producing the means of thermal insulation via molding.

[0021] According to another feature of the invention, the method consists in gluing cover plates respectively onto the outside face of the panel or panels and/or a main face of the bearing structure.

[0022] The features of the invention mentioned above, as well as others, will become clearer after reading the following description of a mode of embodiment, said description being given in reference to the appended drawings, which include:

[0023] FIG. 1 is an exploded view of a partition panel according to the invention,

[0024] FIG. 2 is a cross sectional view in a median plane of a partition panel according to the invention,

[0025] FIG. 2b is a cross sectional view of a detail of a partition panel according to the invention, and

[0026] FIG. 3 is a front view of two partition panels being assembled according to the invention, and

[0027] FIG. 4 is a top view of an embodiment variant of two partition panels being assembled according to the invention.

[0028] The partition panel shown in FIG. 1 comprises a bearing structure (100) consisting of a frame (102), preferably closed, equipped with at least one opening. Two openings (110a and 110b) are shown in this Figure. Advantageously, the bearing structure (100) is made of reinforced concrete.

[0029] The partition panel comprises assembly means (130) positioned in a median plane of the panel in order to allow the assembly of two juxtaposed panels. Advantageously, the upper end field (120a) of the partition panel comprises a recess (122a of 122b) at each of its ends. The means of assembly (130), such as bolts (130a and 130b) are mounted respectively in the recesses (122a and 122b) as shown in FIGS. 1 and 3.

[0030] The means of assembly (130) further comprise a flange (140) that is to be anchored to the bolts (130a and 130b) of two juxtaposed partition panels to assemble them together, as shown in FIG. 3.

[0031] The lower end field (120b) has a recess (124) visible in FIGS. 1 and 3 that is able to incorporate a binding agent to join the partition panel to the structure of a building under construction.

[0032] In another mode of embodiment shown in FIG. 4, the lateral fields (160a and 160b) of the bearing structure (100) are equipped respectively with positioning means (162a and 162b) that are advantageously complementary, such as a tenon (162a) and a mortise (162b). These positioning means (162a and 162b) thus allow the positioning of two partition panels in a same plane when they are juxtaposed. Here, again, the interstices that may exist between two juxtaposed partition panels can be closed with strips of material (310) of the same kind as the cover plates (300) and that must be glued.

[0033] In FIG. 1, the partition panel also comprises means of thermal insulation (200) advantageously made of expanded polystyrene. These means of thermal insulation (200) can also be made of extruded polystyrene or polyurethane. The means of thermal insulation (200) consist, on the one hand, of at least one panel (210) capable of covering respectively one of the main faces (150a or 150b) of the bearing structure (100) and, on the other hand, of at least one protuberance (220) intended to be housed respectively in an opening (110), as shown in FIG. 2a. Thus, the partition panel does not incorporate any thermal bridge likely to accelerate the transfer of heat between its two main faces. Advantageously, the thickness of the panel (210) is greater than or equal to 20 mm.

[0034] In a preferred mode of embodiment shown in FIG. 2a, the means of thermal insulation (200) consist of a panel (210) comprising two protuberances (220a and 220b). Panel (210) is positioned against one of the main faces, in this case the main face (150a), and the protuberances are mounted respectively in the two openings (110a and 110b). Each means of thermal insulation is attached to the bearing structure (100) by gluing, for example using a polyurethane adhesive.

[0035] In a variant mode of construction not shown, panels (210) are positioned respectively against the main faces (150a and 150b) of the bearing structure, and the protuberance or protuberances (220) are associated with either of the panels (210).

[0036] In FIG. 1, the partition panel also includes cover plates (300a and 300b) intended to cover respectively the main faces (150a and 150b).

[0037] In FIG. 2b, the covering plates (300a and 300b) are glued respectively to the outside face of the panel (210) and onto the main face (150a or 150b) (in this case the main face 150b) of the bearing structure (100), and on the exposed walls of the protuberances (220). The adhesive used is preferably polyurethane adhesive.

[0038] It will be understood that when the means of thermal insulation (200) include panels (210) covering the main faces (150a and 150b). The cover plates (300a and 300b) are glued respectively to the external faces of said panels (210).

[0039] The cover plates (300a and 300b) are advantageously laminated panels, galvanized sheet steel or lacquered sheet, stainless steel, PVC, plywood or even cellulosic plates.

[0040] Thus, the walls of a building formed by the partition panels according to the invention are smooth and impervious and, as a result, can be easily washed and do not retain dust. The result is an appreciable reduction in the amount of water necessary to wash them.

[0041] The partition panels according to the invention are produced in the following way. Concrete is poured into a reversible metal mold in which reinforcing scrap has been placed previously. Then the mold is vibrated on a vibrating table to form the bearing structure (100) made of reinforced concrete. The bearing structure (100) is then unmolded, then stored until it has dried completely.

[0042] The means of thermal insulation (200) are produced from panels of material that must be shaped, preferably by cut out, or are manufactured by molding to obtain the panel or panels (210) equipped with their protuberances (220).

[0043] The means of thermal insulation (200) are then glued onto the main face or faces (150) and in the openings (110). The cover plates (300) are then glued respectively onto the external face of the panel or panels (210) and/or a main face (150a, 150b) of the bearing structure (100).

[0044] The conventional dimensions of a partition panel according to the invention are typically as follows:

[0045] 2,600 mm×653 mm×100 mm

[0046] 2,440 mm×613 mm×100 mm

[0047] 2,800 mm×653 mm×100 mm

[0048] The surface mass of a partition panel according to the invention is in the neighborhood of 70 kg/m2, and allows manual installation of the partition panel, in its conventional dimensions, without having to use a crane.

[0049] Other conventional dimensions are planned:

[0050] 2,600 mm×1306 mm×100 mm

[0051] 2,800 mm×1306 mm×100 mm

[0052] Two partition panels being erected and assembled are shown in FIG. 3 in order to participate in the formation of a building divider.

[0053] A first partition panel is raised vertically on a slab of a building in the location of the partition to be built; a binding agent is provided in the recess (124) to join the partition panel and the slab. A second panel is juxtaposed with the first, then is joined to the slab with the same material as the first partition panel. A flange (140) is then mounted and flange-mounted to the bolts (130a and 130b) of the two juxtaposed panels in order to assemble them.

[0054] Any interstices existing between two juxtaposed partition panels or between the partition panels and the slab on which they rest or the ceiling can be closed with a binder that can be covered with strips of material (310) of the same kind as the means of insulation (200) or the cover plates (300).

[0055] The partition panel according to the invention makes it possible to produce building partitions with high thermal insulation properties.

[0056] The smooth external surfaces of this type of panel make them easier to wash.

[0057] The surface mass of this type of panel in its conventional dimensions allows it to be installed without having to use a crane.
