DETAILED DESCRIPTION

With reference to the figures and as recalled above, the invention relates to a construction comprising a sandwich panel wall 1 in which is formed an opening 11 intended to receive a joinery 5 via a pre-frame 2. Thus , sandwich panel wall means a wall which comprises one or more sandwich panels.

In the example shown more particularly in Figures 3 to 10, the wall 1 comprises an assembly of two sandwich panels and the opening 11 is formed in the junction zone of the two sandwich panels. Alternatively, it can be provided that the opening is formed in a single sandwich panel. For example, the sandwich panel or panels may be siding sandwich panels. The sandwich panels may for example be of the Promisol S and / or Promisol V type (Promisol being a registered trademark). The core of the panel is made of insulating material, foam, wool or fiber, for example a polyurethane foam or rock wool. The soul is taken between two skins, preferably formed by sheets.

Figures 3, 4 and 7 show a trimmer 100. However the joinery 5 is not attached to said trimmer 100 unlike the state of the art and one could predict to be exempt from said trimmer.

As illustrated in Figure 2, said construction comprises a receiving structure, called pre-frame 2, adapted to receive the joinery 5.

The pre-frame 2 is made of steel, preferably galvanized steel. The realization of the steel pre-frame allows the pre-framework to withstand heavy constraints, especially when the construction is industrial building type potentially subjected to severe weather.

Said pre-frame 2 has an inner peripheral wing 21 and an outer peripheral wing 23 intended to come around the opening 11, bearing against the inner or outer face of the wall 1. In particular said wings 21, 23 are in support of the part of the inner face, respectively outer, adjacent the opening 11.

Said pre-frame 2 also has a part, called carpentry support 22, which interconnects said inner and outer peripheral wings 21 and 23. The said carpentry support portion 22 is intended to be inserted into the said opening 11 facing the peripheral edge 122. or around, interior opening 11. Said peripheral ring 122 forms the receiving surround of the pre-frame 2. Similarly, the inner peripheral edge of the support 22 forms a joinery receiving environment.

Said construction comprises a carpentry 5. In the example illustrated in the figures, the carpentry 5 comprising a frame 3 and an opening 4. The frame 3 is mounted in the, and fixed to, the support 22 of the pre-frame 2 carpentry.

The frame 3 is in the form of a frame. The frame 3 is fixed to the frame 2 by screwing screw 329 from the inner periphery of the frame 3 and through the receiving support 22 which extends inside the opening 11.

Fixing the frame 3 by screwing through the support 22 of the frame 2 not only allows the frame 3 to be positioned inside the opening 11 on a rigid surface formed by the carpentry support 22 of said pre-frame. frame 2, but also to fix the frame 3 of joinery without visible screw in the closed state of the opening 4, since the carpentry support 22 is hidden by the frame 3 and the inner periphery of the frame 3 is itself masked by the opening 4 in the closed position thereof.

It should be noted that the joinery could not be fixed directly to the inner peripheral edge of the opening in the wall 1 because it is formed by the core of the panels, which does not allow to receive fastening means such as screws.

According to a preferred embodiment, said pre-frame 2 is formed by assembling a frame 230 and a counter-frame 210, the outer peripheral wing 23 forming part of the frame 230 and the inner peripheral wing 21 forming part counter-framework 210.

Said frame 230 and against-frame 210 also include parts 232, 212 able to overlap at least partially from each other to form said carpentry support 22 of the pre-frame 2. Said covering parts are preferably assembled together by means of screws 229.

Preferably, the covering portions 232, 212 comprise pre-drilled orifices that can be positioned facing each other for the assembly of the frame 230 and the counter frame 210 by screwing through said orifices.

The frame 230 comprises a rebate 227 which extends inside the opening 11 and which is closer to the outer face than the inner face of the wall 1 against which the wings of the pre-frame are applied. The rabbet 227 forms an abutment limiting abutment of the joinery 5 in the preframe 2 from inside the construction. Indeed, said rabbet 227 forms a surface against which is applied, via a seal 61, the outer face of the frame of the joinery. Exterior means what is oriented towards the outside of the building.

Said rabbet 227 is formed by a fold of the pre-frame, in particular by a fold of the part 232 of the support 22,

The rabbet 227 extends perpendicularly to the overlapping portions 212, 232 and within the frame formed by said overlapping portions to form a peripheral positioning stop for the joinery. The rabbet 227 is equipped with a seal 61 against which the frame is intended to bear.

The pre-frame 2 comprises a rejingot 228 situated in the opening 11 and closer to the outer peripheral wing 23 than to the inner peripheral wing 21.

The frame 3 extends to the right of rejingot 228 and is further applied to the groove 227 which forms an inverted U. The rejingot 228 is formed by a U-fold of the lower crosspiece of the support 22. In particular, the rejingot 228 is formed by a U-shaped fold of the lower cross member of the frame 230 which forms the lower crosspiece of the support 22 in cooperation with the lower cross member of the counter frame 210.

The part of the rejingot 228 forming the abutment edge of the joinery 5 is also provided with a seal 62. Advantageously and as illustrated in FIG. 6, the seal 62 rises over a portion, for example 10 cm, of the height of the tables of the carpentry support 22 to take into account that the joints 61,62 extend in different planes.

The pre-frame comprises a silicone seal 63 applied to the intersection between the seal 61 of the rebate 227 and the seal 62 of the rejingot portion 228 forming the support edge of the joinery 5.

The free edge of the outer peripheral wing 23 comprises a return 231 making it possible to provide a peripheral seal insertion space 123 between the outer peripheral wing 23 and the outer face of the wall 1 against which the outer peripheral wing 23 is applied.

Said return 231 may be inclined to form a beveled support edge. In the example illustrated in the figures, the inner peripheral wing 21 also comprises an inclined return 211.

The preparation for laying the pre-frame can thus be carried out in the following manner, illustrated in connection with FIGS. 3 to 10.

After cutting the sandwich panel wall to provide the opening 11, the operator positions the frame 230 and the counter frame 210, which are preferably already lacquered, on either side of the opening 11 against the faces corresponding inner and outer wall 1. The frame 230 is positioned on the outer face and the counter frame 210 on the inner face of the wall.

Advantageously, as illustrated in FIG. 2, a peripheral seal 229, such as a sheet edge seal, is applied to the free edge of the part 232 of the frame 230 so as to ensure a thermal break and to prevent the circulation. of air between the outside and the inside of the building at the opening 11 and / or the pre-frame 2.

Preferably, shims 233 are also interposed between the frame and the frame against their overlap area. These shims 233, for example made of wood or plastic, can also form thermal bridge breaking means and protection means during tightening by screwing the frame against the frame.

The pre-drilled orifices provided in the covering portion 232 of the frame 230 are positioned opposite the corresponding pre-drilled orifices formed in the covering portion 212 of the counter frame 210. Clamps 6 are set in place to clamp the frame 230 and the counter-frame 210 on the edges of the opening 11. Then the frame 230 and counter frame 210 are fixed to each other by screwing 229 through the pre-drilled holes and oriented.

Thus, the pre-frame 2 encloses the edges of the opening formed in the sandwich panel wall. The operator can then deposit a seal 61 on the groove 227 of the pre-frame 2 formed by a fold of the uprights and the upper cross member of the part 232 of the support 22, and deposit a seal 62 on the support formed by the above the rejingot 228 of said pre-frame by going up on a given height of the tables of the support 22. Advantageously, the operator also applies a line of silicone to the intersection of the two joints. The operator can set up the frame 3 of the joinery 5 in the frame 2 by engaging it from the inner face of the wall 1 so that it can abut against the rabbet 227 of the pre-frame 2. Wedges 64 can be interposed between the upper cross member and the amounts of the frame 3 and the upper cross member of the support 22 and the amounts of the pre-frame 2 to correctly position the frame 3. The wedging of said upper rails allows to put the seal 62 of the edge of compression support. Clamps 6 can also be used to tighten the frame 3 against the rabbet 227 to compress the rabbet joints.

The frame is fixed on the support 22 of the pre-frame 2 with screws 329 which pass through the frame from the inner edge of the frame to engage the support 22 of the pre-frame 2. Preferably, the frame 3 of carpentry 5 is pre-drilled.

For a better seal, the operator can also deposit a line of silicone on the top of the outer lintel formed by the upper part of the outer peripheral wing 23.

Finally, the operator couples the sash 4 to the frame 3. Advantageously, the operator also places a trim profile 219, called bib, on the frame 230 to mask the junction between the rejingot 228 and the lower rail of the 3.
