A support profile (5) bedded in concrete presents a groove (5A) that receives a profile (6) establishing a connection between the bedded profile and an under surface. A U-shaped part is turned towards the height for rotatively receiving the wings of a connection profile. The case is formed of pressed concrete having the same characteristics and texture of a concrete block used in the wall construction.

Description

Roller shutter drawer with profile.

Technical field

The invention relates to a drawer element for roller blind.

A roller blind consists of a cloth which is rolled on an axis, housing the whole in a drawer.

This drawer is fixed as applied on the wall existing, or is integrated into the carpentry and is housed in the dimensions of the opening to be equipped.

These drawers can also be integrated into the Masonry at the time of construction of living place.

These drawers integrated at the time of Construction are molded expanded polystyrene, coated with fibers to more easily allow plastering to grip will project on the wall.

In the latter case, the problem of the appearance of fissures that appear at the level of the plaster that It covers the concrete blocks that have been used for construction of the walls.

These fissures are located at the level of the junctions between the wall and the drawer.

Indeed, the materials that have served to build the wall have different expansion coefficients than the polystyrene of the drawer, so that cracks appear.

It is known to pour an inverted L drawer on site of concrete in lintel configuration (EP0952297A1).

A drawer is known with profiles that form rails for fixing the lower surface (FR2804157A1).

A formwork carries a solidarity mesh pre-installed, and then the concrete is poured.

These concrete drawers have a section in L inverted and comprise a top wall and a dorsal wall. In these drawers have to fix a plastic bottom surface or aluminum

Fixing the bottom surface results in a trouble.

The invention aims to solve the problems previously mentioned.

For this purpose, the invention aims at a drawer element for roller blind comprising a wall upper and a dorsal wall, characterizing this drawer element because it incorporates a profile called support embedded in the face internal dorsal wall that has a U-shaped part at its base facing up that serves as a channel for the hitch of a union profile.

The invention will be perfectly understood with the help of the description given below as example with reference to the drawing, which represents schematically:

Fig. 1: perspective view of an element of formwork;

Fig. 2: cross section of the element of the Figure 1;

Fig. 3: the drawer element during assembly in the wall;

Fig. 4: a detail of realization at the time of transport;

Fig. 5: the detail of figure 4 during the drawer assembly.

Referring to the drawing, an element is seen 1 monoblock drawer intended to house a blind roller.

This drawer 1 thus presents a wall 2 that delimit a cavity.

The wall comprises an upper wall 2A, a dorsal wall 2B and, accessoryly, two lateral faces 2C.

This drawer comprises a mesh 3 integrated in a concrete.

When the drawer is positioned, your face anterior is flush with the anterior face of the wall.

This front face is intended to receive a plaster.

Drawer 1 is advantageously made of concrete pressed with the same structure and texture as a block of concrete, so that it will be integrated into the block wall of concrete and will offer the plaster intended to cover them characteristics than the wall.

This will therefore prevent the appearance of fissures

It is also a bearing element.

The material used is therefore a concrete pressing that is made with aggregates of smaller dimensions than for cast concrete and whose proportion of water at the time of Manufacturing is less than for cast concrete.

The mechanical properties of a concrete Pressed are different from those of cast concrete. The advantage is which will ensure continuity between the wall and the drawer and offer an ideal support for plastering.

The metal mesh is made of iron bars crossed, comprising rectangular meshes.

Advantageously, the outer side faces 2C of the drawer element have two vertical ribs 4 of way they constitute, with the concrete block that will be juxtaposed to this drawer, a housing for bonding mortar.

To accommodate the roller blind, you have to insert a bottom surface 15 of the drawer as well as a face previous.

For this purpose, the dorsal wall 2B of the drawer element and in particular its internal face comprises a profile called support embedded in the concrete, this embedded profile 5 presenting a channel 5A capable of receiving a second profile 6 called removable joint that establishes a junction between the embedded profile 5 and a lower surface
fifteen.

This support profile 5 is embedded in the face internal dorsal wall, and an upward-facing U-part serves to successively receive a wing 10A, 10B of a profile of Union.

This joining profile comprises means 7 so that occupy a first position called active, in which a part of the union profile appears under the drawer, and a second position called of transport, in which this union profile is housed in the drawer cavity.

Thus, the union profile is protected from the impacts during transport.

This joining profile incorporates a means of hook 7 with the embedded profile channel and a pin 8 in the The bottom surface fits.

This pin 8 is horizontal.

In the mounted position and fit to receive the lower surface, pin 8 on which the surface fits bottom is located at a distance from the bottom face of the drawer and It serves as a song for plastering.

This horizontal pin is supported by a branch 9 vertical call that has a Te 10 on its back whose two wings 10A, 10B and 10A serve to position the profile of union so that its pin can receive the lower surface and whose other wing 10B serves to position the joint profile so that pin 8 is housed in the cavity of the drawer for transport.

Figure 4 shows that, when pin 10B is embedded in the channel of profile 5, profile 6 is protected, since it is inside the drawer. It looks like the part upper profile 6 is not in contact with concrete, but It is facing the top of profile 5, so no there is a risk of scratching this profile 6. Figure 5 shows profile 6 placed before the installation of the lower wall 15.

The two wings of Te 10 are noticeably parallel to the vertical branch that carries said Te.

The embedded profile comprises at the base a U-part that delimits channel 5A for hitching the profile of Union.

The rear face 11 of this U-part is extends upward for a height substantially equal to the length of the wings of the Te, in order to allow the introduction of one or another of the wings of Te 10 for its hitch.

The front face 12 of the profile embedded in level of the U-channel is in the same plane as the inner face of the dorsal wall of the drawer.

Wings 16 serve for anchoring in the concrete.

The fixation of the lower surface is complete with screws that will be fixed to a few squares 13 fixed on the inner faces of the dorsal walls.
