Abstract

In this system, a protective and reinforcing side wall is formed by a sole (S) of a certain height placed on the ground, above which the partition wall (C) proper, made of panels (2), is erected. The sole (S) is produced from prefabricated modules (1) arranged end to end, each including means to be fixed to the ground and to the neighbouring modules. The modules (1) consist of a casing open at its base and at its ends, into which casing has been cast a block of material such as lightweight concrete or synthetic foam. <IMAGE>

Description

The present invention relates to the field of construction of industrial buildings, and more particularly to the fitting out of interior partitions.

These partitions, generally made up of light prefabricated panels must be protected and reinforced in the lower part, given the significant shocks to which they are permanently exposed, in particular on the part of the various handling machines.

The current technique consists in bringing back to the base of the partitions, a concrete sidewall called a bench seat: more precisely, the partition panels are placed in a rail anchored to the ground, then the concrete bench seat is poured along the panels. The bench may be covered with an envelope, usually made of stainless steel.

This technique suffers from several drawbacks, including the installation time due to the size of the formwork to be produced, and the final aspect of the installation of the partitions. Regarding the formwork, we can adopt a simplified process if the bench must be covered with stainless steel: the metal casing is first put in place, then the concrete is poured into it through openings provided for this purpose in the upper wall . However, this implementation remains cumbersome and does not in any way solve the problem of irremovability mentioned above.

The invention was carried out with the aim of overcoming these various drawbacks.

It consists of a protection and reinforcement system for the lower part of partitions, characterized in that it comprises a sole of a certain height, the top of which comprises a groove for receiving the base of partition panels, which sole is formed from prefabricated modules arranged end to end, each comprising means for being fixed to the ground and to the modules neighbors, and consisting of an open envelope at its base and at its ends, into which a block of material such as light concrete or synthetic foam has been poured before installation.

Said sole defines a sidewall at the base of the partition to be protected. If the partition must be protected on both sides as in most cases, the sole is double, that is to say that it defines a sidewall on each side.

In a preferred embodiment, said envelope is made of stainless steel, and it is loaded with a light and insulating concrete, based on polystyrene for example.

Fig. 1 therefore illustrates the invention, implemented to provide protection and reinforcement in the lower part on both sides of a partition C. Conventionally, this consists of prefabricated panels juxtaposed 2.

According to the invention, prior to the installation of the panels, is provided over the entire length of the partition C, a continuous sole S, fixed firmly to the ground. The sole S has a substantial width relative to the thickness of the panels 2, and a height which, generally, is between 20 and 50 cm.

The sole S consists of a series of identical modules 1 placed end to end, which essentially comprise a casing 10 open at its base and at its ends, advantageously made of stainless steel, and filled with a filler material forming a block 11, good thermal insulator and having appropriate mechanical properties. It can be a synthetic foam or a light concrete, based on polystyrene beads for example. Each module is fixed to the ground and to the module previously installed.

As best seen in Figs. 2 and 3, the casing 10 defines at the top of the module 1 a longitudinal groove 12 intended to receive the base of the partition panels 2. After construction of the partition, the sole S therefore forms two sides on each side of the base, brought to be in different rooms where the temperature conditions can be very different. It is therefore necessary to eliminate as much as possible the thermal bridges between the two parts of the envelope 10 on each side of the groove 12. For this purpose, the envelope 10 is subdivided symmetrically into two pieces of sheet metal 13, each folded so as to present a vertical panel, an upper panel with double inclination, and an upper rim forming a part of the groove 12. The two sheet metal parts 13 are joined at the bottom of the groove 12 only by a few transverse isthmus 14 regularly spaced. Similarly, at their base, they are only joined at the ends of the module.

At one of these ends, the bottom connection of the parts 13 is provided by a flat transverse cross member 15. A median upright 16 connects the latter to the bottom of the groove 12, which upright carries two centering pins 17 arranged one above the other.

At the other end, a flat cross member 18 connects the two parts 13 similarly to the cross member 15. The cross member 18 is surmounted by an angle iron 19 which defines with it a space 20 open towards the outside. A median upright 21 connects the top of the angle 19 and the bottom of the groove 12, which has holes 22 for receiving the centering pins 17. The crosspiece 18 has two or more spaced holes, provided for receiving fixing screws to the ground.

The concrete or foam block 11 comes flush with the outer face of the uprights 16 and 21, the outer edge of the cross member 15 and that of the angle iron 19. It completely fills the envelope 10 and constitutes the ground support of the module.

As already noted, the modules 1 must be fixed securely, as in many applications, in particular in the field of the food industry, and for hygienic reasons, a correct seal is necessary between the lower edges of the envelope 10 and the ground. To make it easy, provision is made for the lower edges 13a, 13b of the casing 10, FIGS. 2, 3, protrude downward relative to the underside of the block 11. When installing the modules 1, the edges 13a, 13b are received in grooves or grooves made in the ground, which are then filled with a seal suitable, such as silicone sealant, or polyurethane-based mortar.

It is also necessary to have a tight junction between the adjacent edges of the envelopes of neighboring modules. This junction can be achieved by means of a seal, for example made of rubber, having two opposite grooves for receiving said edges. As a variant, as shown in FIGS. 5a, 5b and 6, the junction is produced by interlocking, a strip 23 forming the male part being welded to the internal face of the casing 10, projecting from its edge at one end, while at the other end, the female part or groove results from the superimposition by welding on the same internal face of the envelope of a first strip 24 set back from the edge, and of a second strip 25.

To build a sole S, two parallel grooves are first formed in the ground, intended to receive the lower edges 13a, 13b of the envelopes 10. A first module 1 is put in place. It is anchored in the ground at the level of the cross-member 18, the space 20 being provided to allow screwing. The module is therefore held by this end, and over its entire length by the lower edges of the envelope engaged in the ground. A second module 1 is placed after the first. It is connected to it by the centering pins 17, and by interlocking the adjacent edges of their envelopes, as illustrated in FIGS. 4 and 6. As can be seen in this last figure, the blocks 11 of filler material are then applied one against the other, of so there is no break in insulation. In turn, the second module is anchored to the ground at its free end, by screwing the crosspiece 18. This is done over the entire length of the partition to be built, after which the panels 2 are placed in the grooves 12. If water, electricity, compressed air, etc. are installed along the partition, cleaning passages for the pipes or sheaths in the block 11 and the casing 10 of the corresponding module before its installation. Such a passage is shown in FIG. 12, consisting of a horizontal tube 26 embedded in the block 11 and opening at the end. The tube 26 can pass right through the module, or stop at the point of a tap in the casing 10.

Fig. 14 schematically shows such a tap 27 in the upper panel of the wall 13 of a module, tap made with an external collar, at the end of a vertical hole in the block 11, for the passage of a conduit outlet 28. The collar is welded to the duct 28, which is connected below a sink or hand basin 29 fixed above the module, against the partition panel 2.

To make angles and crossings, special modules can be provided, in the form of T, L and X. It is also possible to provide a range of modules shorter than modules 1, to directly make S soles whatever their length.

The module 1 'shown in FIG. 7 is used to make a single sole, that is to say a sole forming reinforcement only on one side. This module is in all respects similar to the module 1 described above, comprising a block 11 of insulating filler material, an envelope 10 ′ in two parts 13, 13 ′ joined by points, with the same end means: low crosspieces, angle iron, uprights, centering pins. On the other hand, the part 13 ′ of the envelope is not shouldered, so that the groove 12, instead of being central, is offset on the outside of the module, its outer edge being perpendicular to the vertical wall of the envelope part 13 '. In the embodiment shown, a single lower edge 13a of the casing 10 ′ is extended beyond the base of the block 11 which constitutes the bearing surface of the module, hence the need for a single groove in the floor for laying. Of course, as a variant, the lower edge of the part 13 ′ can also be extended, if the sealing on the outside needs to be carried out with as much care as on the inside.

Modules 3 and 3 'of Figs. 8 to 10 differ very little from modules 1 and 1 'in their structure. Like them, they comprise an envelope 10 or 10 ′ enclosing a block of insulating material 11 and defining an upper groove 12 for receiving partition elements 2.

However, considering their lower part, we see that the block 11 does not completely fill the volume delimited by the envelope 10 or 10 ', but rather, there is reserved a free space 30 intended to receive a sealing concrete, which can be flowed through channels 31 passing through the block 11 from the bottom of the groove 12.

On the other hand, a cross 18 with an angle 19 to define a space 20 are reproduced at the two ends of the modules 3 and 3 '. And on the cross member 18, jacks 32 are mounted in place of screws for fixing to the ground, which is carried out by means of rods 34 engaged from the groove 12 in calibrated channels 33 passing through the block 11, and in holes in the ground aligned with the channels 33. In another embodiment of the modules 3 and 3 ′, the angle 19, and therefore the space 20 above the crosspiece 18 are eliminated, the screw of the jacks 32 being covered above the cross member 18, by means of a closed tube portion, for example.

For the production of a bench seat S in new premises, the modules 3 or 3 'are first arranged on a first slab 35, the lower edge of the casings 10 or 10' being slightly raised. They are connected end to end by the adjacent end edges of their casings 10 or 10 ', the jacks 32 allowing adjustment. Then, drilling means are engaged in the channels 33 to provide in the slab for receiving the rods 34 which are then put in place. Note that an advantage of this method of fixing lies in the possibility of fixing the last module arriving against a pre-existing wall or partition.

Once all the modules 3 or 3 ′ have been placed, the sealing concrete is poured through the channels 31, which comes slightly beyond laterally under the lower edges of the modules. Finally, a finishing slab drowns these lower edges, symbolized by the thin line 36. In a slightly different way of proceeding, the waterproofing concrete is poured at the desired height just before the installation of the modules 3 and 3 ', the channels 31 then serving as an overflow for the excess concrete.

In renovations, the modules can be placed on the slab carrying the floor covering, after a strip of it has been cut and removed.

In the connection system between neighboring modules illustrated in FIG. 11, a connecting and sealing tape 37 is used, for example of the same material as the casing 10, which is housed by its two sides in two grooves formed in the end edges of the casings 10, by welding by strip points 24 and 25 as previously described. Once the ribbon 37 has been placed between two modules, a sealing weld is produced between the adjacent edges of the two envelopes 10.

The T-module of FIG. 12, bearing the mark 4, is used for the T-junction of two partitions. As shown, its two branches 4b and 4c are single sole elements, and its foot 4a is a double sole element.

Compared to the other modules described above, the sheet metal parts 13 of its casing 10 have only one inclined section instead of two above the vertical section. Its slope is preferably at least greater than 30 ° relative to the horizontal, to ensure good flow of the washing water.

On the other hand, the walls 13 and 13 'have, at some distance above their lower edge, a small longitudinal recess 40. In the recess 41 formed below the recess 40, a set of wires is added by welding crossed 42, which is used for attaching a cement or finishing resin, with which one comes to form for example a rounding as shown schematically by the broken line in FIG. 13.

As a variant, the recess 41 can be provided to admit tiling. In this case, at the location of the step 40, the sheet is normal to the vertical plane of the wall 13; and on the surface of the hollow 41, it is advantageously perforated to ensure better attachment of the fixing adhesive to the tiling.

For the primary fixing to the ground of the module, lateral tabs 43 added by welding to the bottom of its walls 13 and 13 ′ may be provided, which will be screwed or pointed, before being covered with cement or finishing resin, or by the tiling.

In Fig. 12, the element 4b of the module 4 is shown incomplete, without its filling concrete 11, to reveal its internal structure. On the other hand, the filling concrete 11 is visible in the element 4a and in FIG. 13: it is stopped very close to the lower edge of the walls 13, the free space 30 reserved for the admission of sealing concrete having a very reduced uniform height, of the order of 1 to 2 cm. The realization of the waterproofing concrete according to the technique of pouring it at the desired height before the installation of the module is facilitated.

Of course, variant modules according to the invention can combine the characteristics of two modules 1, 3 and 4, or 1 'and 3'.

Fig. 15 shows a module 5 designed to make the end of a sole S adjacent to a door, of which the frame conventionally comprises uprights with a U-shaped section 50 to engage on the edge of the partition panels 2.

The side wall 13 of the envelope of the module 5 is extended by a wall 51 which completely covers the end. Preferably, instead of being orthogonal to the wall 13, the wall 50 forms an obtuse angle with it, advantageously of the order of 135 °, to allow correct release of the door leaves during opening.

In addition, in line with the groove 12, a section of U-shaped section 52 is placed vertically on the end, welded by the end of its wings to the wall 50. Said section 52 has a width equal to the thickness of the partition panels 2. Thus, when the partition panel adjacent to the door is put in place on the module 5, the element 52 ensures its extension to the ground for the reception of the amount of frame 50. Between the latter and the module, the sealing is carried out by means of a silicone seal in the interstices 53.

Obviously, the system of the invention is much simpler and faster to use than the other known systems. To this advantage, is added that of a possible removable: if it is planned at the start, the disassembly of a sole poses no problem and, of course, the modules which constituted it are perfectly reusable. Note also that the system of the invention induces a significant cost reduction at the level of the panels 2, the surface of which is reduced by the height of the sole S.
