Description

Construction kit with floor and part sheet of associated mounting.

Introduction

The present invention relates to a kit of construction for the assembly of floors and similar structures, and more particularly for mounting outdoor terraces of wood.

State of the art

The wooden exterior terraces are usually made from plates or sheets of floor wood placed on an armor, constituted in particular by battens previously fixed to the ground or placed on the ground.

Taking into account exposure to the weathering, these wooden terraces are often made in hard exotic woods, and it is necessary to provide care particular to the assembly of the wood sheets in order to have in count the possible deformations of these sheets under the effect of thermal cycles and humidity variations.

Fixing the wood sheets on the armor is traditionally done by means of screws stainless steel, which cut through the sheets to fix them on the battens. In order to allow the dilation of the wood, a game is left between two adjacent sheets, which is generally 3 to 8 mm depending on the species of wood.

For exotic wood species, hardness of the wood is such that prior drilling is mandatory for avoid the bursting and splitting of the wood, respectively the screw breakage. This previous drilling is followed by a milling to penetrate the screw heads to the flush These stages are long and laborious.

Wood treatments (for some oils or others) may pose problems. The oil stagnates over the screws, changes its color and wood has a tendency to flake relatively quickly. In addition, some woods secrete some tannins that corrode the screws very quickly.

When placement takes place, at least two people should help each other to make and maintain separation required between each sheet (use of several wood coves, blade support, screwed, etc.). This long work and thorough causes a cost overrun of labor important.

In order to simplify the assembly of terraces, the application WO-A-95/25856 suggests use metal fasteners in the form of squares, nailed or screwed onto the battens between two sheets of adjacent ground. The mounting part comprises a vertical leg which presents in each of its faces some points that form highlight horizontally so that they can bite into the wood of the edge of each of the adjacent sheets facing each other. One piece Fixation of this type eliminates perforation of the sheets, but does not truly allow a gain of time when it takes place the assembly since the positioning of the fixing parts and of Blades is hard. In addition, this technique is not adapted to hardwoods - in particular to exotic hardwoods such such as teak, padouk or ipé, much appreciated for terraces exteriors - since the tips and nails penetrate poorly in the wood.

Application WO-A-02/066756 describes another piece square-shaped mounting, comprising a horizontal wing with a lower face that comes into contact with the upper face of a track and an upper face that comes into contact with the subcara of a sheet of soil. The horizontal wing thickness is selected so that it defines a first brace dimension between the blade and the strip. The mounting part also includes a wing vertical that extends at a height less than the thickness of the sheet. Each of the two faces of the vertical wing have some stubs that form horizontally highlighted and sized cooperating with a homologous profile groove formed in the edge of the corresponding sheet. The mounting piece therefore ensures a function of fixing the sheets to the reinforcement, but defines likewise, a brace thickness between adjacent sheets and reinforcement to allow the expansion of the sheets and ensure the moisture evacuation.

The assembly part presented in the document WO-A-02/066756 prevents screwing of the sheets and allows a relatively simple and fast assembly. However, although this assembly piece is described as allows a good circulation of air and water, the slots in the ridges form areas of water accumulation that are of easy access. The songs are therefore favorable areas for the development of molds or foams, which damages the aesthetics from the terrace.

US Patent No. 6,453,632 presents a piece of assembly made as a U-shaped connector and comprising two branches This connector fits on the bottom faces of two adjacent parallel floor sheets, coupling each of the two branches in a slot of a respective sheet. According to one of the variants described, each branch is constituted by two legs parallel, each provided with a weatherstrip on the top. The weatherstrips of the same branch are turned in opposite directions and they are coupled in an area of trapezoidal section at the bottom of the groove when the floor sheet is lowered vertically on the connector

WO 01/59234 describes a floor that It comprises base elements provided on their upper faces of dove-shaped rails. The floor sheets as soon as themselves are provided on their lower faces with grooves with complementary profile and are coupled longitudinally over the rails from one end of the base plate. This document also proposes a plurality of alternative forms for the rail of the base element.

Object of the invention (problem to be solved by the invention)

The objective of the present invention is to propose another type of assembly for the realization of floors or terraces, which do not present the disadvantages mentioned above.

General description of the claimed invention with its main advantages

The present invention relates to a kit of construction according to claim 1, comprising a sheet of ground that has a bottom face provided with a groove longitudinal as well as a mounting piece for this sheet of ground. The mounting part comprises a base plate suitable for being fixed on a support structure, presenting the plate base a bottom face that comes into contact with the structure of support and an opposite upper face. It will be appreciated that the plate base comprises at least one anchoring means on its face upper, which cooperates with the longitudinal groove in the lower face of the floor sheet, the anchoring means being designed so keep the floor sheet in the vertical direction after insertion in the longitudinal groove.

The mounting piece therefore allows a fixation of the floor sheet by its lower face. As the medium Anchoring is located under the blade, it is not visible. It will be observed in addition that the present assembly piece allows the fixing of Floor sheets without screwing through the sheets. This is particularly advantageous for the realization of floors or terraces with relatively hard exotic wood species, such as for example teak, padouk and ipé. In addition, the floor sheets do not they need grooves in their edges, which is more aesthetic and suppresses areas of water accumulation. So, the mounting piece according to the invention allows a simple and discreet assembly of the sheets of soil.

The anchoring means is essentially a leg perpendicular to the base plate and provided with an anchoring means on a face of the leg. The anchoring means comprises less a busty that forms essentially horizontally. This stud is preferably supported by the upper part of the leg It is sized so that it cooperates with a groove of homologous profile on a wall of the longitudinal groove of the sheet of floor to keep the floor sheet in the vertical direction after insertion of the stud in the groove. So, to fix the floor sheet to the armor, the mounting piece is first place fixed to the armor and then the sheet is placed on the mounting piece so that the leg penetrates the groove longitudinally and then the sheet moves in the direction of the stud to make it penetrate the groove.

Two grooves may also be provided in opposite walls of the longitudinal groove, both suitable for cooperate with the busty, which avoids having to verify the position of the groove before mounting the sheet on the piece of mounting.

In a preferred variant, the base plate It comprises two pairs of legs provided on top of lugs to cooperate with two longitudinal grooves on one side bottom of a sheet of soil, all the lugs being oriented in the same way.

The base plate is preferably provided of a top that forms protruding on its upper face, on the side opposite to the side of the leg that supports the hooking means. The position of this stop is determined so that the sheet is find in contact with the stop once the stud is inserted in the slot. This cap is preferably positioned on the edge of the base plate, since it allows then, when the assembly takes place, define a dimension of brace with an adjacent sheet of soil. In this case it blocks also the adjacent floor sheet in position on its piece of respective assembly. It will be noted that the removal of the cap (already be removable or for example by milling), release the floor sheet adjacent in the transverse direction, which can then be decoupled from the anchoring means to be replaced. After of the replacement of the sheet, it can be locked by fixing on the initial stop point, an element of similar thickness. So it is possible to replace a worn or broken floor sheet without having than disassemble adjacent sheets.

The base plate according to the invention has preferably a generally rectangular shape, of the order of magnitude of the width of the floor sheet to be supported, which ensures good stability to the sheet. Advantageously the plate base is made so that it has a central rib reinforcement with a previously defined thickness, and some areas slimmed down, which preferably define slopes descending from the central rib to the edges to facilitate the evacuation of retained water in these parts. To level of the central rib, the base plate then defines a thickness of brace between the floor sheet and the armor.

To facilitate the alignment of the pieces of assembly when placement takes place along a track, the base plate is advantageously provided, in one of its ends of a tongue, and at the opposite end of a recess intended to receive the tongue of an adjacent piece.

The mounting part is advantageously a part of plastic material molded in one piece. The material will be selected to present good mechanical properties and resist Weathering and aging.

It only remains to be noted that the assembly part of the kit according to the invention can be used for fixing wood sheets in various types of assemblies, whether in some horizontal or inclined planes, and even vertical. The present fixing device therefore allows the realization of floors and terraces, but also of wall coverings and coffered ceilings

According to another aspect, the invention relates to a floor according to claim 10.

Finally, the present invention relates to also to a method according to claim 11.

Description with the help of the figures

Other peculiarities and characteristics of the invention will become more clearly apparent from the detailed description of an advantageous embodiment presented then, by way of illustration and referring to the attached plans. These show:

Fig. 2: a longitudinal section view of the assembly part of Fig. 1, on which a floor sheet;

Fig. 3: a sectional view A-A of the assembly part of Fig. 1.

In the figures, the same reference signs designate identical or similar elements.

A first embodiment of a piece of assembly 10 of a construction kit according to the invention is illustrated in Fig. 1. It comprises a suitable base plate 12 to be mounted on a support structure, typically a Armor formed by battens. As seen in Fig. 2, the base plate has a lower face 14 in contact with a trace 18 of the armor and an opposite upper face 18. In the present variant, the base plate 12 has a general shape rectangular (for example a length of 109 mm and a width of 50 mm). The base plate 12 is advantageously made so that present a central reinforcement rib 20 with a thickness previously defined (for example 4 mm) and thinned areas 22, which preferably define descending slopes from the central rib 20 towards the edges to facilitate the evacuation of water retained in these parts 22. However, the base plate 12 could alternatively be made as face solid.

The piece 10 is advantageously molded into a single piece in a plastic material that is selected to present Good mechanical properties and resist the weather and the aging. You can for example use a plastic material such as PE, PVC or PP, or also composite materials (if necessary loaded with glass fibers) such as a compound based on polyamide.

The base plate 12 is provided with means suitable to allow fixation to the underlying track 16, namely holes 24 intended to receive one or more screws of assembly (not shown). These holes 24 can advantageously being oval to allow for an adjustment margin if, at the time of positioning of piece 10, hole 24 will happen to be above a fixing screw to the armor. In that case, an oval hole 24 will then allow place the mounting screw a little further. It is also possible to increase the number of screw holes to avoid this difficulty. Finally, in case of multiple holes, the bottom of the holes may be provided with a plastic veil that will be easily drilled for the hole that will be chosen and will ensure the tightness for others.

It will be appreciated that the present mounting piece 10 allows a fixation of the floor sheets below. To this Finally, the piece 10 comprises anchoring means on the face upper 18 of the base plate 12 and cooperating with grooves longitudinal 26 on a lower face 28 of a floor sheet 30 (see Fig. 2).

These anchoring means comprise preferably two pairs of legs 32 on the upper face 18 of the base plate 12, cooperating each pair of legs 32 with a groove 26. In addition, each leg 32 has, preferably in the part upper, a stud 34 that extends horizontally on one side of the leg and sized so that it cooperates with a slot 38 of homologous profile in a wall of the longitudinal groove 26 correspondent.

As can be seen in figures 1 to 3, the bumpers 34 are all turned to the same side on their legs 32 respective. This preferred configuration allows assembly single of a floor sheet 30 on the fixing piece 10 associated, first lowering the sheet 30 on the piece of so that the legs 32 penetrate the longitudinal grooves 26, and then the sheet 30 is displaced (to the right in Fig. 2) to introduce the pins 34 in their respective slots 38. In In this position, the sheet 30 is held in the vertical direction. It will be noted that each slot 26 preferably has a opening slightly larger than the legs 32 provided with the studs 34, in order to facilitate the introduction of the latter in slots 26.

In addition, part 10 advantageously comprises a stop 40 in projection on the upper face 18 of the base plate 12 and arranged at the end of the plate 12 opposite the lugs 34. The position of this stop 40 is selected so that when the sheet 30 is displaced to fit grooves 38 and studs 34, the sheet 30 comes into contact with the stop 40. This stop 40 It is preferably positioned on the edge of the base plate 12, since it allows then, when assembly takes place, define a brace dimension with a floor sheet adjacent.

It will be understood according to Fig. 2, that after mounting the fixing part 10 (against the fixing part of the right 10 ') and the placement of the sheet 30 in the position indicated, the fact of fixing the next 10 '' mounting piece (a the left of the mounting piece 10), causes the blockage of the floor sheet 30. Indeed, the stop 40 '' of the piece 10 '' is placed against the floor sheet 30, preventing any translation in the direction that allows the release of the sheet of floor 30. The stop 40, 40 '' therefore has a double function of blocking and bracing between adjacent sheets; its thickness can be for example 4 mm.

It will also be noted that the elimination of stop 40 '', for example by milling, releases the floor sheet 30 which can then be shifted back to the left (in the Fig. 2) to be disassembled. After the placement of a new floor sheet on piece 10, it can be fixed - for example by glued - at the point of stop 40, a cove of the same dimensions to block the floor sheet 30 again. This allows a Easy replacement of floor plates 30, without disassembly of adjacent sheets.

To facilitate the alignment of the pieces of assembly 10 when placement takes place, base plate 12 it is advantageously provided, at one of its ends, with a tab 42, and at the opposite end of a recess 44 intended for receive the tongue of an adjacent piece. Mounting parts they are therefore fixed along a track coupled to each other others, inserting the tongue of a mounting piece into the recess of an adjacent mounting piece.
