Description

METHOD FOR ESTABLISHING A PILLAR IN COMPOSITE MATERIAL, PILLAR AND SYSTEM OF CORRESPONDING PILLARS

The present invention relates to a method of placing a pillar of composite material on a floor, said composite material being loaded with sand, from at least two parallelepipedal hollow blocks.

By sand-filled composite material is meant a material comprising sand and a binder, which may be cement and water (to form concrete), resin, or other connecting element.

It also relates to such a concrete pillar and a corresponding pillar system. It finds a particularly important application although not exclusive in the field of concrete pillars for garden gate, but can also and of course be used to support a frame or to compose a wall or a railing.

Already known pillars made of sand-filled composite material made of concrete, for external structures mounted progressively from the stack of blocks. Whether these blocks are initially solid, or that they are hollow and then be completed by pouring concrete inside, such pillars have drawbacks.

They require large amounts of concrete, and can not be manufactured quickly.

It is indeed necessary, after realization of the foundations, to pose the pillars by casting them by height of one m / day, then to fix the hats. of the Mandatory times of concrete drying are then necessary and few are the installers who respect them. Pillars of poor quality result, heavy and expensive. Also known (US 4,703,600) pillars formed of hollow-shaped blocks that are again filled with concrete and / or held together by vertical metal rods, with junction mortar sealing between blocks, occupying an internal volume clogging.

If such provisions allow to obtain strong pillars resistant to bending for example due to a cantilever, they are heavy, complicated to implement and require significant drying times.

The present invention aims to provide a method of laying pillars and a corresponding pillar better than those previously known to the requirements of practice in particular that it allows a pillar installation decreasing the set up time and the number of days intervention by two or more.

When the concrete is used for the blocks, there is then a decrease in the amount of concrete used of the order of 60% avoiding any problem of cracking observed on the pillars of the prior art and / or their seal, generating cracks many disputes.

To do this, the invention starts from the idea of producing hollow composite pillars, with no other method of fixing between them only glue, the pillar blocks once formed remaining hollow and empty, and holding each other only by bonding. Such an assembly is surprisingly very strong, including a pivoting gate door is hung, the engorged doors rather diverting the skilled person from such a solution, and despite the exposure of the pillar to bad weather.

For this purpose, the invention proposes in particular a method of placing a pillar made of sand-filled composite material on a floor from at least two hollow parallelepipedal blocks of stackable composite material in the form of a hollow sleeve, characterized in that on a base plate of the pillar, made integral with the ground and comprising interlocking means with the lower part of a first block, said nesting means and / or the lower part of said first block are coated with a high performance glue, said lower part is fitted on the interlocking means, the upper part of the first block and / or the lower part of at least one second block is coated with the high performance glue, the second block is fitted on the first, then we possibly renew the operation with one or more additional blocks, before coating the upper part of the last block and / or the base of an upper cap that is just applied on said last bl oc to form said composite pillar, the latter being hollow and completely devoid of vertical reinforcing bar or holding. No stiffening or holding rod or sealing mortar type material recessed parts between them are indeed intended to be inserted and / or implemented during the assembly of the pillar hollow, on the height of said pillar definitively.

The hollow character of the pillar also allows the passage of electric lighting wires and / or the insertion of a motorization of the closing of a gate, or a mailbox, etc., and this in a modular manner.

High performance adhesive is understood to mean an adhesive which has a minimum tear strength of 1.4 MPa at room temperature and humidity.

In advantageous embodiments, one and / or the other of the following provisions is also used:

- the blocks and the sole are made of concrete; - Before digging a hole in the ground, pouring a concrete sole in the hole, and said seal plate pillar base in the sole;

the blocks are formed by resin loaded with sand; - the sole is metallic;

at least two of the blocks comprising means for attaching a rotary gate, the latter being fixed on the pillar which serves as support for said gate and its axis of rotation; - The interlocking means of a block on the other, and a block on the plate or on the cap having one groove and the other a vertical crown of complementary shape of said groove to fit together one in the other on a given height, the throat and the crown of glue are coated and we come to dock one on the other.

Advantageously, a vertical pressure is exerted during the casing. The invention also provides a pillar obtained with the method as described above.

It also proposes a hollow vertical pillar made of sand-filled composite material comprising a plurality of elements, namely a base plate of the pillar, at least two hollow parallelepipedal blocks made of composite material loaded with sand, stacked in the form of a hollow sleeve and a cap, said elements comprising means for interlocking with each other and means for securing with each other only formed of high performance glue.

The pillar is devoid of rod or other reinforcing metal frames and / or vertical support. As indicated above, the hollow character of the pillar allows the passage of the electric lighting wire and / or the insertion into the pillar of a motor, but also the establishment in-house of a mailbox, d a motor, etc. The invention also proposes a system of two portal pillars as described above. Advantageously it comprises a sole on which is fixed the plate, the blocks and the sole being made of concrete.

In another advantageous embodiment, the sole is metallic.

Advantageously also the blocks are formed by resin loaded with sand.

In an advantageous embodiment the concrete sole is elongated, at least prefabricated in part, and comprises two pillar base plates disposed respectively at each end of the sole, for the respective two pillars.

Advantageously, the pillar comprises means for attaching a rotary gate to the lateral outer walls of at least two of said blocks with or without a flap of said gate.

In an advantageous embodiment, the interlocking means of a block on the other, and a block on the plate or on the cap respectively comprise on their junction face a groove and at least one vertical crown of shape complementary arranged to fit one into the other on a given height.

Advantageously, the determined height is greater than 5 cm, or greater than 8 cm or 10 cm.

Also advantageously, the plate comprises two concentric rings s' nested in two corresponding recesses of the first block.

In another advantageous embodiment, the sole is of trapezoidal shape and the plate of high strength concrete.

Advantageously, the layer of adhesive during its application is of thickness between 2 mm and 8 mm.

In an advantageous embodiment, one of the blocks comprises an inner box forming a mailbox and / or receptacle of a motorization of the gate.

The lightweight and modular nature of the blocks allows their easy marketing, for example on a pallet comprising in the form of a package, blocks, turntables, soles and hat, all sold for example in supermarkets for a non-professional consumer, the ease of editing allowing to address this type of audience.

The invention also provides a method of mounting a pillar as described above. The invention will be better understood on reading the following description of embodiments given as non-limiting examples.

It refers to the drawings which accompany it in which: Figure 1 is an exploded perspective view of a pillar according to an embodiment of the invention. Figure 2 is a partial side view, in section of another embodiment.

Figure 3 shows an embodiment of the interlocking means between blocks. Figure 4 is a front view of a pillar according to one embodiment of the invention with portal.

Figures 5 and 6 show two embodiments of the attachment means of the portal on the pillar of Figure 4. Figure 7 is a perspective view of another embodiment with prefabricated elongate sole.

FIG. 1 shows a composite composite vertical pillar 1 comprising several elements, namely a concrete base 2 provided with a baseplate 3 of the abutment, at least two parallelepipedic hollow concrete blocks 4 stacked in the form of a hollow sleeve and a hat 5.

The elements comprise interlocking means 6, 7 and 8 which will be detailed below, and securing means 9 of one with the other formed of high performance glue.

The glue to be used for the assembly of the elements is, for example, cement mortar known under the name C2S or a chemical sealing glue from the American company 3M.

In particular, an epoxy adhesive having, after two days of drying, a compressive strength of 30 MPa, a flexion of 15 MPa and an adhesion of 2.7 MPa, applicable at temperatures of between 5 ° C. and 40 ^° C. is sufficient to obtain a solid pillar according to the invention. The sealing plate consists of concrete with high compressive strength between 30 and 70 mega pascal. It comprises interlocking means 6 comprising a double crown 10 formed of two concentric rings 11 and 12 allowing greater seating than the pillar elements which, for their part, withstand less effort and have only one crown 13 on their upper part. On their lower part, each of the blocks, on the other hand, has a recess or groove 14 of complementary shape to the crowns 12 and / or 13, in recess so as to either allow cooperation with a single ring (block to block connection) or allow the connection with the plate with two concentric rings.

The adhesion surface between the first pillar element, namely the first block, and the bottom plate is between 50 and 80% relative to the ground surface of the pillar, that is to say of its horizontal section overall. .

In other words, for a pillar of 40cm / 40cm, ie a surface of horizontal section of 0.16m ² , the bonding surface between the plate and the first pillar must be between 40 and 80%, and advantageously between 50 % and 70%, a platinum surface with crown of an deployed value between 0.08 and 0.128m ² .

The lateral surfaces intended to be bonded are, for their part, made in a rough texture (or grooved) to allow better adhesion of the foundation concrete. In Figure 1 there is also shown on one side of the pillar hinges 15 to allow the attachment of a gate flap.

Examples of these hinges are detailed with reference to Figures 5 and 6 below.

The shutter of the gate can thus rotate about an axis of rotation, with a door to fix which is acceptable for the pillar as constituted.

FIG. 2 shows in section the assembly of several blocks 4 on the base plate 3 according to an embodiment of the invention similar to that of FIG. 1.

Subsequently the same reference numbers were used to designate the same elements. In FIG. 2, the rings 11 and 12, or 13, forming an interlocking staircase, allow a solid attachment and respect the percentages of bonding surface according to the invention more particularly described here. FIG. 3 shows another embodiment of the interlocking means 16 formed on one side of a throat-shaped groove 17 made in the junction surface 18 between blocks, and on the other side by a flange 19 having on either side of the shoulder surfaces 20, thereby increasing the contact surfaces in blocks and / or block and hat or platinum.

FIG. 4 shows a gate leaf 21 mounted on a pillar 22 consisting of six superimposed blocks 23 and a cap 24, the material constituting the nested pillar blocks being, for example, a Mega Pascal compressive strength concrete, or between 30 and 70 Mega Pascal. FIGS. 5 and 6 show embodiments, respectively, of means 25 and 26 for fixing the gate.

These fixing means comprise hinges 27, 28 and can be placed by the manufacturer, directly on the blocks, or fixed during the pause of the pillar by the user.

FIG. 5 shows more particularly means 25 comprising a metal plate 28 on which the hinge 27 is fixed.

The male portion of the hinge 27 has an axis 29 on which fits the female portion 30 of the hinge attached to the gate.

In the other embodiment of Figure 6, instead of fixing a plate, the male portion 31 of the hinge is fixed by means of a screw 32 directly into the concrete with a tilting blade 33 or key which s' press inside the block in the locked position. More precisely, FIG. 6 shows a hinge 26 provided with a screw 32 with a key 33, a plate 34 and a nut 35.

At the end of the screw is fixed the hinge 31 provided with an axis of rotation 36 which is engaged on the female part 37 of the hinge of the door, known in itself.

After drilling the hollow block screwed on the side face of the block by screws 28 ', and on which the hinge 27 is fixed, the screw is then introduced and then the key 33 is put back vertically and the nut is tightened, which allows effective fixation in the hollow pillar. Figure 7 is a perspective view showing an elongated precast concrete base 40 provided on both sides, at its ends, blocks 41 and 42, parallelepipedigues interconnected by a concrete spar 43. Chague pavé comprises two protuberances 44 parallélépipédigues for example concrete, located on both sides, and perpendicular to the spar to complete the base of the sole.

Each of the blocks is provided with a plate 45 sealed in the corresponding block and constituting the base of a composite pillar 46 of the type described with reference to FIG.

The sole 40 thus constitutes a prefabricated concrete base placed on a level ground 47, then covered with pebbles 48.

The installation of the pillar then becomes an operation of great simplicity, the base may consist of a block or several elements to be assembled, here again by gluing or sealing with cement or other binder.

The manufacture of a pillar will now be described with particular reference to FIG.

After having excavated the foundations in the ground of the pillar or pillars to be produced, the concrete sole 2 is cast in which the base plates 3 are also placed in position (leaving the interlocking means of the upper surface of the soles), then said soles are allowed to solidify for the necessary time, for example a day.

The base 3 is then firmly sealed, the interlocking means are cleaned, for example with a detergent, to leave the platinum concrete a rough but clean surface of dust.

The glue 9 is then applied in a layer of 2 to 8 mm on the contact surfaces of the two rings 11 and 12, as well as on the contact surfaces of the groove 14 of the first block, then the block is put in place on the plate and adjusted, its own weight allowing a pressurization of the contact surfaces during the taking of the latter (a few minutes). This setting up can be done manually. The weight of each hollow block which depends on its dimensions will for example be 25 kg for a pillar of 30 x 30.

The lower and upper joining means of the first and last block are then coated with adhesive in the same way, and the last block placed on the first and so on until the cap, the own weight of the elements for excellent application. Then the hinges are put in place as well as the portal.

As is obvious and as also follows from the above, the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all the variants and in particular those where the hinges have a shape different from those particularly described and where the interlocking means are constituted differently, while allowing a sufficient bonding surface, or in which the glue used is different but having the same bonding characteristics as the adhesives mentioned above. Similarly, the hat can be formed in several pieces and / or be replaced by a connecting piece, with a roof, a terrace and so on.

The fastening means in the ground may comprise a sole, as more particularly described, but may also be pile-type elements, or fastening screws or spit sized to take the bending and / or shear forces if there takes place.
