Definitions
- the invention relates to a building system for constructing vertical walls, which comprises wooden building blocks substantially of rectangular parallelepipedal shape that are intended to be placed substantially horizontally one beside another and substantially vertically one on top of another in a vertical wall and comprising an upper face, a lower face, an inner face, an outer face and two abutting faces in the wall.
- the upper and lower faces of each block comprise at least a first groove extending over the entire length of these faces.
- the system also includes at least a first block alignment tongue intended to be placed horizontally between the first grooves of adjacent blocks in the wall.
- the invention relates to any type of wall comprising at least one part constructed from wood. It may apply to walls of dwellings, such as the outside walls, supporting walls and internal partitions. The invention may also be used for constructing swimming pools, saunas, noise-barrier walls, windbreak walls, etc.
- Wooden bricks are easier to handle and in general easier to assemble.
- the cost of wooden bricks compared to logs is also lower since, for the same amount of wood, the manufacture of bricks requires fewer tree trunks.
- U.S. Pat. No. 5,890,332 discloses a modular building system using reconstituted wooden blocks.
- metal rods are fixed vertically in a slab, preferably a concrete slab.
- Wooden bricks having a hole at their center, slip over these rods, one on top of another.
- the rods serve as anchor bolts and make it possible for the bricks, stacked on top of one another, to be clamped together over the height of the wall.
- Such stacks of wooden bricks are placed side by side along the wall.
- Vertical and horizontal alignment keys which are placed in grooves provided on the surface of the bricks, allow adjacent bricks to be aligned pairwise. The bricks are also bonded together.
- Such a building system does not allow simple, rapid and effective assembly of the various modules. This is because the building system requires the manufacture and use of numerous “small” parts, namely the alignment keys, thereby making the manufacture and assembly of the parts lengthy and costly in labor. In addition, the building system does not allow straight walls to be obtained.
- the use of alignment keys, as described in this prior art allows adjacent bricks to be aligned only pairwise, but does not allow alignment of the bricks over the entire wall. Moreover, these keys do not keep the bricks in place one against another, since it is necessary to bond the bricks together. This constitutes an additional step in the construction of a wall, which step moreover makes the building system environmentally unfriendly owing to the use of adhesive.
- Australian patent AU 2 841 577 describes a building system for constructing walls using wooden bricks.
- the bricks have longitudinal grooves on two opposed longitudinal faces.
- the bricks are joined together using tongues having a length equal to the length of the wall to be constructed.
- the tongues are placed horizontally between the grooves of the blocks.
- One object of the invention is to provide a building system for constructing walls partly made of wood, which remedies the aforementioned problems of the prior art.
- One particular object of the invention is to provide a building system for constructing, for a lower cost, stable walls that are sealed and easy and rapid to construct.
- the building system according to the invention is characterized in that the edge between the upper face and the outer face of the blocks includes a chamfer covering part of the first groove over its entire length and in that the first tongue includes a notch having two facets over its entire length, the first facet of the notch being aligned to fit into the first groove, the second facet of the notch being designed to bear against the chamfer, and the face on the opposite side to the second facet forming an oblique slope for water to flow away toward the outside of the wall.
- the first tongue provides sealing between the vertically adjacent blocks in the wall. This is because rainwater that trickles along the bricks of a wall or that infiltrates between the blocks runs down along the flow-off surface formed by the oblique slope of the first batten. The water is thus extracted from the wall. Moreover, moist air may condense in the form of droplets on contact with the wall between the blocks. These droplets drop on to the flow-off surface of the batten and are removed from the wall.
- Such a system makes it possible to erect walls very simply and very quickly, and for lower cost. This is because the first tongue is easily lodged in the first grooves thanks to the notch and the chamfer.
- the first batten fulfills two functions, that of a batten for aligning and holding the adjacent blocks together and that of a sealing part.
- the number of parts to be manufactured and assembled is reduced, as is also the manufacturing, assembly and labor costs.
- the first tongue is preferably made as a single piece.
- the profile of the chamfer is constant. It may be flat or rounded.
- the facets of the notch may be flat or rounded.
- the notch with two facets consists of a rebate.
- the length of the first tongue is more than twice the length of a first groove of a block. This is because the first grooves of the upper faces of all the blocks placed horizontally one beside another in a wall forms a long continuous groove. A first tongue, laid in this long groove, makes it possible to align and keep together, owing to its length, these lower blocks over an entire wall face.
- the upper blocks that have to be laid on the lower blocks possess, on their lower longitudinal face, a first groove. Thanks to this first groove, it is easy to place and assemble the upper blocks on the lower blocks.
- the tongue thus makes it possible to align and hold together, over its entire length, not only the upper blocks but also the upper blocks with respect to the lower blocks.
- the first grooves of any one block are arranged symmetrically one with respect to another.
- the first grooves are substantially in the same position for all the blocks.
- Another object of the invention is to provide a system that allows the construction of walls providing an acoustic, thermal and moisture seal.
- the building system according to the invention is characterized in that the relative dimensions of the first tongue with respect to the dimensions of the first grooves are calculated so that the tongue is slightly compressed in the cavity formed between the grooves of the adjacent blocks.
- the first tongue slightly compressed between the first grooves forms, over its entire length, a seal between the vertically adjacent blocks.
- This seal constitutes an effective barrier that prevents both moisture and air passing through it.
- Such a system therefore makes it possible to produce, rapidly, easily and for a lower cost, a particularly impervious, straight and stable wall.
- Another object of the invention is to reduce to a minimum the tensile stress on the surface of the blocks and to guarantee easy assembly of wooden blocks that “work” and lose their original shape.
- the building system according to one embodiment of the invention is characterized in that the upper and lower faces of the blocks have a second groove extending over the entire length of these faces and in that it includes at least a second block alignment tongue designed to be placed between the second grooves of adjacent blocks.
- the two grooves in each of the opposed faces serve to reduce the tensile stress on the blocks.
- the magnitude of cracks (especially their size and number) which appear in the blocks is reduced.
- the density of the wood of the blocks is not uniform. Wood deforms, especially under what is called the “core drawing” effect. As a result, the surfaces of the blocks become bowed or dished—it is difficult to assemble blocks that do not have flat contact surfaces.
- By having a second tongue between the second grooves of the blocks it is easier at the moment of assembly to mutually stabilize the adjacent blocks on surfaces that include the second grooves. In particular, this thus prevents the blocks from “rolling” or “pitching” one with respect to another.
- the length of the second tongue is more than twice the length of a second groove of a block.
- it is even easier to align and assemble a plurality of blocks over quite a large part of the face of a wall.
- the relative dimensions of the second tongue with respect to the dimensions of the second grooves are calculated so that the tongue is slightly compressed in the cavity formed between the grooves of the adjacent blocks.
- the second grooves of a given block are arranged symmetrically one with respect to another.
- the second grooves are substantially in the same position for all the blocks.
- the first and/or second grooves have a triangular cross section.
- a groove with such a cross section has the advantage, unlike a groove of rectangular cross section, of avoiding gaps between the tongue and the groove. This is because such a groove has only two surfaces for contact with the tongue.
- first and/or second grooves have a semicircular or circularly arcuate cross section.
- part of the first tongue which is intended to be accommodated in the first groove and/or the second tongue have a circular, square or diamond-shaped cross section.
- the tongues are made of wood (solid wood or fiber components). Wooden tongues are easy and inexpensive to produce, completely environmentally friendly and can be easily handled. Moreover, wood is a relatively rigid material that accepts being slightly compressed. In a different embodiment, the tongues are made of plastic.
- Another object of the invention is to provide a building system that can allow service ducts and/or pipes to pass through a wall that remains perfectly sealed.
- the first or the second tongue is a service duct or pipe. Installation of the ducts or pipes takes place during assembly of the blocks—no particular additional installation is necessary.
- the ducts or pipes placed between the grooves of the blocks may themselves form a seal.
- the relative dimensions of the ducts or pipes with respect to the dimensions of the grooves are in particular calculated in such a way that the duct or pipe is slightly compressed in the cavity formed between the grooves of adjacent blocks.
- the blocks include a hole extending between the two second grooves of these blocks.
- certain blocks have a hole extending from one of the second grooves of these blocks and opening onto the inner (or outer) face of these blocks. The hole allows the ducts or pipes to emerge from the wall.
- holes may be perforated before assembly (on the block manufacturing site) or at the moment of assembly, depending on the construction requirements.
- the building system includes at least one sheath or brace intended to pass through these holes so as to make effective and sealed connections and outlets for the ducts or pipes.
- the blocks have at least a third groove on each of their abutting faces and in that the system includes at least a third tongue designed to be placed between the third grooves of the abutting faces.
- the relative dimensions of the third tongue with respect to the dimensions of the third grooves are calculated so that the tongue is slightly compressed in the cavity formed between the grooves of the adjacent blocks. In this way the wall is sealed at the transverse faces of adjacent blocks.
- the blocks are placed in a staggered fashion, thereby ensuring that the blocks are better held together one with respect to another.
- the third tongues have the same length as the length of the third grooves or are shorter than them.
- the third tongues are made of solid wood or of fiber components.
- the third grooves of the lateral faces do not form an intersection with the first grooves and/or second grooves of the longitudinal faces, in particular so that the tongues used vertically and horizontally do not impede one another.
- the block-abutting faces have at least a fourth groove extending substantially vertically over the entire height of the abutting face, one of the ends of said fourth groove opening onto the chamfer.
- These fourth grooves form gutters between the horizontally adjacent blocks. These gutters allow air to circulate and therefore provide ventilation between the horizontally adjacent blocks. If moisture-laden air penetrates between the abutting faces of the blocks, it is guided in the ventilation grooves. If the moisture of the air condenses as droplets, the droplets fall onto the sloping surface of the immediately lower first tongue and are removed from the wall.
- the block-abutting faces have at least a fifth groove extending substantially vertically over the entire height of the abutting face, one of the ends of said fifth groove opening onto the chamfer of the upper face, between the end of the fourth groove and the first groove;
- the system includes a set of seals designed to be lodged in the fifth grooves.
- the seal provides perfect sealing between the abutting faces of the blocks in the wall. Owing to the position of the ends of the fifth groove, any condensation appearing at these ends will be removed along the chamfer, the fourth groove of the block and the flow-off surface of the tongue located immediately below the block.
- the position of the fourth and fifth grooves is substantially the same for each block.
- Another object of the invention is to provide a building system that allows the blocks to be fastened together easily.
- At least one block has at least a first drill hole extending between the upper and lower faces, substantially perpendicular to these faces.
- the system includes at least one anchor bolt intended to be slid through the first drill hole.
- the blocks also include at least a second drill hole extending from the upper face and substantially parallel to the first drill hole.
- the anchor bolt can then be slid through the first drill hole of a first block and screwed into the second drill hole of a second block placed beneath the first block.
- This system makes it possible for two vertically adjacent blocks to be fixed simply, and thus allows the various components of the wall to be fixed easily and securely.
- a method of assembling blocks in pairs allows subsequent modification of the wall. This is because it is easy to cut openings in a wall thus produced, while still preserving the retention and alignment of the wall in its entirety.
- the anchor bolts apply a certain pressure between the vertically adjacent blocks in the wall.
- the anchor bolts provide constant contact between the tongues and the grooves over the entire length of the tongues. In this way, the wall is perfectly sealed.
- the building system makes it possible for the alignment of the wall blocks to be checked and adjusted almost perfectly.
- the straightness of the second block may be checked using a laser. This technique makes it possible to construct perfectly straight walls in which the position of the blocks can be individually checked.
- the building system allows the construction of walls that have to be absolutely perfectly sealed (for example for the construction of swimming pools or saunas).
- additional seals may be placed between the adjacent surfaces of the blocks and/or between the second facet of the notch and the chamfered edge of the blocks.
- these seals are made of hydrophobic rubber, for example closed-cell rubber. Rubber is an environmentally friendly material.
- the building system allows the construction of supporting walls for building components.
- certain blocks are narrower than the others, so that these blocks, placed beside one another in the wall, form a recess in the wall intended to support building components.
- This wall recess creates a support surface for accommodating building components such as joists for supporting a floor or rafters, purlins or ridge beams for supporting a roof.
- building components such as joists for supporting a floor or rafters, purlins or ridge beams for supporting a roof.
- the blocks are made of solid wood, the system according to the invention making it possible to construct walls for dwellings serving both as interior walls and exterior walls.
- Solid wood has well-known insulation properties which make it a material of choice for constructing exterior walls.
- the cost of constructing such a dwelling is less since it is unnecessary to cover such a wall for the interior of the dwelling, both as regards insulation and esthetics.
- bricks made from wood of different colors it is possible to construct walls that are patterned.
- the blocks may also be made of fiber components (for example compreg wood or sealed MDF or laminated wood, etc.).
- Another object of the invention is to provide a wall that includes a part constructed using a building system according to the invention.
- Another object of the invention is to provide building blocks as used in the building system according to the invention.

- FIG. 1 is a perspective view of an example of a wall under construction, made using the building system according to the invention.
- the wall 1 comprises wooden building blocks 2 of rectangular parallelepipedal shape, which are placed beside one another and on top of one another in a staggered fashion.
- the blocks are preferably made of solid wood. However, they may also be made of fiber components.
- the upper horizontal longitudinal face of the blocks 2 includes two grooves 5 a , 5 b parallel to the longest side of the face and running along the entire length of this face.
- the lower horizontal longitudinal face of the blocks 2 includes two grooves 5 c , 5 d parallel to the longest side of the face and running along the entire length of this face.
- the two grooves 5 a , 5 b of the upper face are arranged symmetrically with the two grooves 5 c , 5 d of the lower face.
- the edge near the intersection between the upper face and the outer face of the blocks 2 has a chamfer 12 .
- the profile of the chamfer 12 is constant and flat. It may also be rounded or of molded shape.
- the chamfer 12 covers part of the first groove 5 b over its entire length.
- a first tongue 6 a being a trapezoidal cross section includes a rebate 60 .
- the first tongue has a first part 61 of substantially square cross section and a second part 62 of substantially trapezoidal cross section connected to the first part 61 .
- the rebate 60 has a first facet 62 c that rests in the first groove 5 a .
- the rebate 60 has a second facet 62 a that rests on the chamfer 12 of the lower blocks 2 and forms a surface complementary to the profile of the chamfer 12 . Since the second facet 62 a of the tongue 6 a is complementary to the profile of the chamfer 12 , the clearance and space between these two surfaces are reduced to a minimum. A seal (not shown) may be placed between these two surfaces.
- the surface 62 b on the opposite side to the second facet 62 a forms a flow-off surface 62 b for water to flow away.
- the first part 61 of the first tongue 6 a is placed between the grooves 5 a and 5 c of the blocks 2 over the entire length of the wall 1 .
- the first part 61 of the tongue 6 a makes it possible to hold in place and to align, over the length of the wall 1 , the blocks 2 placed horizontally beside one another on a given course. It also makes it possible to hold in place and align the blocks 2 placed one on top of another on two course.
- the water flow-off surface 62 of the first tongue 6 a stops on the outer vertical face of the blocks 2 .
- the flow-off surface 62 may also extend very slightly beyond the outer vertical face of the blocks 2 .
- the flow-off surface 62 b allows the water to be away from the wall 1 , thus preventing moisture from penetrating in the wall 1 .
- a second tongue 6 b is placed between the grooves 5 b and 5 d of the blocks over the entire length of the wall 1 .
- the tongue 6 b reinforces the retention and alignment of the blocks 2 with respect to one another that is provided by the first tongue 6 a.
- Tongues 6 a , 6 b as long as possible, preferably with a length equal to the length of the wall 1 , are used.
- the first and second tongues 6 a , 6 b may advantageously be chamfered on their edges.
- the grooves 5 a , 5 b , 5 c , 5 d serve as means of reducing internal tensile stresses in the wooden blocks 2 .
- the magnitude (number, size, etc.) of cracks appearing in the wood is reduced.
- the blocks 2 constituting the first course of the wall 1 are fixed to foundations in a conventional manner (not described here).
- the foundations may consist of a first foundation (not shown) made of concrete on which a concrete surround (not shown) rests.
- the blocks 2 of the first course are fastened to this surround.
- the blocks 2 have, on each of the abutting faces, a vertical groove 7 extending between the upper and lower longitudinal faces. Tongues 8 are placed between the horizontally adjacent blocks 2 in the grooves 7 . The tongues 8 make it possible to hold in place and align the horizontally adjacent blocks 2 in pairs.
- the grooves 7 preferably have a circularly arcuate cross section, the circular arc being equal to or shorter than a semicircle.
- the tongues 8 of circular cross section are held in place between the grooves 7 of two horizontally adjacent blocks 2 , over the entire height of these blocks 2 .
- the tongues 8 are slightly compressed in the space created by the grooves 7 , so as to ensure contact between the tongues 8 and each surface of the grooves 7 .
- the wall is sealed at the abutting faces of the blocks 2 .
- the blocks 2 also have, on each of the abutting faces, two vertical grooves 71 and 72 opening onto the chamfer 12 .
- the vertical grooves 71 closest to the outer face of the blocks form ventilation gutters between the abutting faces of the adjacent blocks.
- Tongues (not shown) or seals are placed in the grooves 72 .
- each block 2 has four drill holes 4 a , 4 b , 4 c , 4 d that extend vertically between the lower and upper horizontal longitudinal faces of the block 2 .
- a block 2 is placed on a row of blocks 2 already joined together.
- An anchor bolt 14 is slid through the drill holes 4 a , 4 c of the block 2 to be fastened and is screwed into two drill holes 20 a , 20 c in one of the two blocks 2 placed beneath.
- an anchor bolt 14 is slid through the drill holes 4 b , 4 d of the block 2 to be fastened and then screwed into two drill holes 20 b , 20 d in the other block 2 placed beneath.
- FIG. 2 is a cross-sectional representation of two superposed blocks according to a preferred embodiment of the invention.
- the block 2 a is placed on top of the block 2 b in the wall 1 .
- the blocks 2 a and 2 b have grooves 5 a , 5 b , 5 c , 5 d of identical right-angled triangular cross section.
- the grooves 5 a , 5 b are placed symmetrically with respect to the grooves 5 c , 5 d and the grooves 5 a , 5 c symmetrically with respect to the grooves 5 b , 5 d.
- a tongue 6 b of square cross section is kept slightly compressed in contact over the length of the wall 1 between the grooves 5 b and 5 d of the blocks 2 b and 2 a respectively.
- the first part 61 of a tongue 6 a of square cross section is kept in contact, slightly compressed, over the length of the wall 1 between the grooves 5 a and 5 c of the blocks 2 b and 2 a respectively.
- the area of the cross section of the second tongue 6 b (and of the first part 61 of the first tongue 6 a respectively) is equal to or slightly greater than that of the cross section of the space formed by the grooves 5 b , 5 d (and the grooves 5 a , 5 c respectively).
- the length of the sides of the tongues 6 b (and the first part 61 of the first tongues 6 a respectively) is equal to or slightly greater than the length of the sides of the grooves 5 b , 5 d (and 5 a , 5 c respectively).
- the tongues 6 a , 6 b which ensure that the blocks 2 are held in place and aligned, are made of a material that is not completely rigid, such as wood, so as to be able to be compressed between the grooves 5 b , 5 d and 5 a , 5 c .
- the tongues 6 a , 6 b are kept compressed by the anchor bolts 14 that hold the blocks 2 a and 2 b together. There is thus a line of contact between the tongues 6 a , 6 b and each surface of the grooves 5 a , 5 b , 5 c , 5 d of the blocks 2 a , 2 b over the entire length of these grooves.
- the second part 62 of the tongue 6 b is thus kept in contact on the chamfer 12 of the block 2 b over the length of the wall 1 .
- the tongues 6 a , 6 b may be bonded in the grooves 5 a , 5 b , 5 c , 5 d .
- the tongues 6 a , 6 b may be made from various materials, such as wood, rubber, plastic.
- the blocks 2 a , 2 b have, along the lower face, a groove or drip 13 placed between the outer edge of this face and the grooves 5 a , 5 b .
- the drip 13 blocks the water that would have a tendency to run along the lower face of the block 2 a toward the interior of the wall 1 .
- the drip 13 of the block 2 a is placed above the flow-off surface 62 b of the first batten 6 a . The water blocked in the drip 13 thus drops onto the flow-off surface 62 b and runs away toward the outside of the wall 1 .
- a seal 16 may be placed between the upper face and the lower face of the blocks 2 a and 2 b over the entire length of the wall 1 .
- a seal (not shown) may also be placed between the abutting faces of the pairwise horizontally adjacent blocks 2 .
- the seal is made of a hydrophobic material, such as closed-cell rubber.
- FIG. 8 shows a front view of a wall constructed using the system according to the preferred embodiment of the invention.
- the block 2 a rests on and is fastened to the blocks 2 b using anchor bolts 14 a , 14 b , 14 c , 14 d .
- the block 2 a has two drill holes 4 a and 4 b and two drill holes 4 c and 4 d (not shown) of slightly larger diameter than that of the anchor bolts 14 a , 14 b , 14 c , 14 d in order to embed the anchor bolt heads and the compression washers (see also FIG. 2 ).
- the drill holes 4 a , 4 b , 4 c , 4 d extend vertically between the upper face and the lower face of the block 2 a and are preferably produced during manufacture of the block 2 a.
- the blocks 2 b have two drill holes 20 a and 20 b and two drill holes 20 c and 20 d (not shown) that extend vertically from the upper face of the blocks 2 b .
- the diameter of the drill holes 20 a , 20 b , 20 c , 20 d is smaller than the diameter of the anchor bolts 14 a , 14 b , 14 c , 14 d .
- the length of the drill holes 20 a , 20 b , 20 c , 20 d depends on the size of the anchor bolts 14 a , 14 b , 14 c , 14 d and is less than the height of the blocks 2 b , so as not to pass through these blocks.
- the anchor bolts 14 a , 14 b are inserted into the drill holes 4 a and 4 b of the block 2 a and are then screwed into the drill holes 20 a , 20 b of the blocks 2 b so as to fasten the block 2 a to the blocks 2 b on which the block 2 a rests.
- the drill holes 20 a and 20 b are preferably made at the time of assembly, by using the drill holes 4 a and 4 b as guides, in order to ensure that that the drill holes 20 a and 20 b are correctly aligned with the drill holes 4 a and 4 b .

Abstract
The invention concerns a building system for constructing vertical walls using wooden building blocks. The parallelepiped blocks comprise on their upper and lower surfaces a first groove (5 a) extending over the entire length of said surfaces. The ridge between the upper surface and the outer surface of the blocks includes a chamfer (12) folding down part of the first groove over its entire length. The system further comprises a first block aligning tongue (6 a) designed to be arranged horizontally between the first grooves of adjacent blocks in the wall. The first tongue includes a double-panel incision. The first panel of the incision is engaged in the first groove, the second panel of the incision is pressed against the chamfers of the blocks. The surface opposite the second panel forms an oblique slope for draining off water.
Description
- The invention relates to a building system for constructing vertical walls, which comprises wooden building blocks substantially of rectangular parallelepipedal shape that are intended to be placed substantially horizontally one beside another and substantially vertically one on top of another in a vertical wall and comprising an upper face, a lower face, an inner face, an outer face and two abutting faces in the wall. The upper and lower faces of each block comprise at least a first groove extending over the entire length of these faces. The system also includes at least a first block alignment tongue intended to be placed horizontally between the first grooves of adjacent blocks in the wall.
- The invention relates to any type of wall comprising at least one part constructed from wood. It may apply to walls of dwellings, such as the outside walls, supporting walls and internal partitions. The invention may also be used for constructing swimming pools, saunas, noise-barrier walls, windbreak walls, etc.
- Known in the prior art are timber constructions in which the walls consist of logs or wooden beams of a size equal to the length of the walls and arranged one on top of another.
- This type of construction is relatively expensive both in terms of raw material and labor. This is because it is necessary to use long logs (that is to say those with the length of the walls). In addition, transporting and assembling on the worksite very long logs are operations difficult and expensive to carry out.
- Moreover, these constructions have major sealing problems. This is because, since wood is a material that works, it is difficult to obtain logs that remain perfectly straight. In addition, through the effect of time, gaps form between the logs, greatly reducing the thermal, acoustic and moisture sealing among others of the building.
- Also known in the prior art are timber constructions produced using wooden bricks. Wooden bricks are easier to handle and in general easier to assemble. The cost of wooden bricks compared to logs is also lower since, for the same amount of wood, the manufacture of bricks requires fewer tree trunks.
- U.S. Pat. No. 5,890,332 discloses a modular building system using reconstituted wooden blocks. According to that patent, metal rods are fixed vertically in a slab, preferably a concrete slab. Wooden bricks, having a hole at their center, slip over these rods, one on top of another. The rods serve as anchor bolts and make it possible for the bricks, stacked on top of one another, to be clamped together over the height of the wall. Such stacks of wooden bricks are placed side by side along the wall. Vertical and horizontal alignment keys, which are placed in grooves provided on the surface of the bricks, allow adjacent bricks to be aligned pairwise. The bricks are also bonded together.
- Such a building system does not allow simple, rapid and effective assembly of the various modules. This is because the building system requires the manufacture and use of numerous “small” parts, namely the alignment keys, thereby making the manufacture and assembly of the parts lengthy and costly in labor. In addition, the building system does not allow straight walls to be obtained. The use of alignment keys, as described in this prior art, allows adjacent bricks to be aligned only pairwise, but does not allow alignment of the bricks over the entire wall. Moreover, these keys do not keep the bricks in place one against another, since it is necessary to bond the bricks together. This constitutes an additional step in the construction of a wall, which step moreover makes the building system environmentally unfriendly owing to the use of adhesive.
- It should also be noted that under the pressure of the anchor bolts that keep the bricks of a given stack together, said bricks are deformed at their center. This results in a distortion of the wall, which then does not have a straight support surface. The use of anchor bolts for each stack of bricks also makes any subsequent modification of the wall (opening for a window, door, etc.) difficult.
- Finally, this system does not solve the problem of sealing the construction since these walls are less sealed the more the bricks are deformed under the pressure of the anchor bolts.
- Australian patent AU 2 841 577 describes a building system for constructing walls using wooden bricks. The bricks have longitudinal grooves on two opposed longitudinal faces. The bricks are joined together using tongues having a length equal to the length of the wall to be constructed. The tongues are placed horizontally between the grooves of the blocks. Although this system does allow bricks to be rapidly assembled in order to form a wall, it does not solve the problem of how to seal the construction.
- One object of the invention is to provide a building system for constructing walls partly made of wood, which remedies the aforementioned problems of the prior art.
- One particular object of the invention is to provide a building system for constructing, for a lower cost, stable walls that are sealed and easy and rapid to construct.
- In this regard, the building system according to the invention is characterized in that the edge between the upper face and the outer face of the blocks includes a chamfer covering part of the first groove over its entire length and in that the first tongue includes a notch having two facets over its entire length, the first facet of the notch being aligned to fit into the first groove, the second facet of the notch being designed to bear against the chamfer, and the face on the opposite side to the second facet forming an oblique slope for water to flow away toward the outside of the wall.
- Such a system makes it possible to construct walls that are particularly well sealed. The first tongue provides sealing between the vertically adjacent blocks in the wall. This is because rainwater that trickles along the bricks of a wall or that infiltrates between the blocks runs down along the flow-off surface formed by the oblique slope of the first batten. The water is thus extracted from the wall. Moreover, moist air may condense in the form of droplets on contact with the wall between the blocks. These droplets drop on to the flow-off surface of the batten and are removed from the wall.
- Such a system makes it possible to erect walls very simply and very quickly, and for lower cost. This is because the first tongue is easily lodged in the first grooves thanks to the notch and the chamfer.
- The first batten fulfills two functions, that of a batten for aligning and holding the adjacent blocks together and that of a sealing part. The number of parts to be manufactured and assembled is reduced, as is also the manufacturing, assembly and labor costs.
- Advantageously, the first tongue is preferably made as a single piece. Advantageously the profile of the chamfer is constant. It may be flat or rounded. The facets of the notch may be flat or rounded. Advantageously, the notch with two facets consists of a rebate.
- Advantageously, the length of the first tongue is more than twice the length of a first groove of a block. This is because the first grooves of the upper faces of all the blocks placed horizontally one beside another in a wall forms a long continuous groove. A first tongue, laid in this long groove, makes it possible to align and keep together, owing to its length, these lower blocks over an entire wall face.
- Moreover, the upper blocks that have to be laid on the lower blocks possess, on their lower longitudinal face, a first groove. Thanks to this first groove, it is easy to place and assemble the upper blocks on the lower blocks.
- The tongue thus makes it possible to align and hold together, over its entire length, not only the upper blocks but also the upper blocks with respect to the lower blocks.
- Thus, it is possible to construct very straight, stable walls easily and quickly, and for a lower cost.
- Advantageously, the first grooves of any one block are arranged symmetrically one with respect to another. Preferably, the first grooves are substantially in the same position for all the blocks.
- Another object of the invention is to provide a system that allows the construction of walls providing an acoustic, thermal and moisture seal.
- For this purpose, the building system according to the invention is characterized in that the relative dimensions of the first tongue with respect to the dimensions of the first grooves are calculated so that the tongue is slightly compressed in the cavity formed between the grooves of the adjacent blocks.
- Thus, the first tongue slightly compressed between the first grooves forms, over its entire length, a seal between the vertically adjacent blocks. This seal constitutes an effective barrier that prevents both moisture and air passing through it.
- Such a system therefore makes it possible to produce, rapidly, easily and for a lower cost, a particularly impervious, straight and stable wall. This is because a single part—the first tongue—serves simultaneously as seal between vertically adjacent blocks, as part for aligning and holding together adjacent blocks, and as a part for removing water from between the adjacent blocks.
- Moreover, such a system provides an environmentally friendly construction, since it makes use of only nonpolluting and renewable materials.
- Another object of the invention is to reduce to a minimum the tensile stress on the surface of the blocks and to guarantee easy assembly of wooden blocks that “work” and lose their original shape.
- For this purpose, the building system according to one embodiment of the invention is characterized in that the upper and lower faces of the blocks have a second groove extending over the entire length of these faces and in that it includes at least a second block alignment tongue designed to be placed between the second grooves of adjacent blocks.
- In the case of wooden blocks, especially solid wooden blocks, the two grooves in each of the opposed faces serve to reduce the tensile stress on the blocks. By increasing the number of grooves, the magnitude of cracks (especially their size and number) which appear in the blocks is reduced.
- Moreover, the density of the wood of the blocks, especially when they are made of solid wood, is not uniform. Wood deforms, especially under what is called the “core drawing” effect. As a result, the surfaces of the blocks become bowed or dished—it is difficult to assemble blocks that do not have flat contact surfaces. By having a second tongue between the second grooves of the blocks, it is easier at the moment of assembly to mutually stabilize the adjacent blocks on surfaces that include the second grooves. In particular, this thus prevents the blocks from “rolling” or “pitching” one with respect to another.
- Advantageously, the length of the second tongue is more than twice the length of a second groove of a block. Thus, it is even easier to align and assemble a plurality of blocks over quite a large part of the face of a wall.
- Advantageously, the relative dimensions of the second tongue with respect to the dimensions of the second grooves are calculated so that the tongue is slightly compressed in the cavity formed between the grooves of the adjacent blocks.
- Advantageously, the second grooves of a given block are arranged symmetrically one with respect to another. Preferably, the second grooves are substantially in the same position for all the blocks.
- According to a preferred embodiment, the first and/or second grooves have a triangular cross section. A groove with such a cross section has the advantage, unlike a groove of rectangular cross section, of avoiding gaps between the tongue and the groove. This is because such a groove has only two surfaces for contact with the tongue.
- According to another embodiment, the first and/or second grooves have a semicircular or circularly arcuate cross section.
- Advantageously, that part of the first tongue which is intended to be accommodated in the first groove and/or the second tongue have a circular, square or diamond-shaped cross section.
- Advantageously, the tongues are made of wood (solid wood or fiber components). Wooden tongues are easy and inexpensive to produce, completely environmentally friendly and can be easily handled. Moreover, wood is a relatively rigid material that accepts being slightly compressed. In a different embodiment, the tongues are made of plastic.
- Another object of the invention is to provide a building system that can allow service ducts and/or pipes to pass through a wall that remains perfectly sealed.
- For this purpose, the first or the second tongue is a service duct or pipe. Installation of the ducts or pipes takes place during assembly of the blocks—no particular additional installation is necessary.
- Advantageously, the ducts or pipes placed between the grooves of the blocks may themselves form a seal. The relative dimensions of the ducts or pipes with respect to the dimensions of the grooves are in particular calculated in such a way that the duct or pipe is slightly compressed in the cavity formed between the grooves of adjacent blocks.
- Advantageously, the blocks include a hole extending between the two second grooves of these blocks. Thus, it is possible to make, in a simple manner, a vertical connection between horizontal ducts or pipes.
- According to another particular embodiment, certain blocks have a hole extending from one of the second grooves of these blocks and opening onto the inner (or outer) face of these blocks. The hole allows the ducts or pipes to emerge from the wall.
- These holes may be perforated before assembly (on the block manufacturing site) or at the moment of assembly, depending on the construction requirements. Thus, it is possible to produce, very easily and quickly, customized and concealed networks of ducts or pipes with access and connection points at very precise positions.
- Advantageously, the building system includes at least one sheath or brace intended to pass through these holes so as to make effective and sealed connections and outlets for the ducts or pipes.
- In one particular embodiment of the invention, the blocks have at least a third groove on each of their abutting faces and in that the system includes at least a third tongue designed to be placed between the third grooves of the abutting faces.
- Preferably, the relative dimensions of the third tongue with respect to the dimensions of the third grooves are calculated so that the tongue is slightly compressed in the cavity formed between the grooves of the adjacent blocks. In this way the wall is sealed at the transverse faces of adjacent blocks.
- Preferably, the blocks are placed in a staggered fashion, thereby ensuring that the blocks are better held together one with respect to another. Advantageously, the third tongues have the same length as the length of the third grooves or are shorter than them. Advantageously, the third tongues are made of solid wood or of fiber components.
- Advantageously, the third grooves of the lateral faces do not form an intersection with the first grooves and/or second grooves of the longitudinal faces, in particular so that the tongues used vertically and horizontally do not impede one another.
- In one particular embodiment of the invention, the block-abutting faces have at least a fourth groove extending substantially vertically over the entire height of the abutting face, one of the ends of said fourth groove opening onto the chamfer.
- These fourth grooves form gutters between the horizontally adjacent blocks. These gutters allow air to circulate and therefore provide ventilation between the horizontally adjacent blocks. If moisture-laden air penetrates between the abutting faces of the blocks, it is guided in the ventilation grooves. If the moisture of the air condenses as droplets, the droplets fall onto the sloping surface of the immediately lower first tongue and are removed from the wall.
- Likewise, if moisture-laden air penetrates between the chamfer and the two-facet notch of the first batten and condenses as droplets, these either run along the chamfer or drop into the fourth groove. The moisture is easily removed from the wall.
- According to one particular embodiment of the invention, the block-abutting faces have at least a fifth groove extending substantially vertically over the entire height of the abutting face, one of the ends of said fifth groove opening onto the chamfer of the upper face, between the end of the fourth groove and the first groove; the system includes a set of seals designed to be lodged in the fifth grooves.
- The seal provides perfect sealing between the abutting faces of the blocks in the wall. Owing to the position of the ends of the fifth groove, any condensation appearing at these ends will be removed along the chamfer, the fourth groove of the block and the flow-off surface of the tongue located immediately below the block.
- Preferably, the position of the fourth and fifth grooves is substantially the same for each block.
- Another object of the invention is to provide a building system that allows the blocks to be fastened together easily.
- For this purpose, at least one block has at least a first drill hole extending between the upper and lower faces, substantially perpendicular to these faces. The system includes at least one anchor bolt intended to be slid through the first drill hole.
- The blocks also include at least a second drill hole extending from the upper face and substantially parallel to the first drill hole.
- The anchor bolt can then be slid through the first drill hole of a first block and screwed into the second drill hole of a second block placed beneath the first block.
- This system makes it possible for two vertically adjacent blocks to be fixed simply, and thus allows the various components of the wall to be fixed easily and securely. In addition, such a method of assembling blocks in pairs allows subsequent modification of the wall. This is because it is easy to cut openings in a wall thus produced, while still preserving the retention and alignment of the wall in its entirety.
- Moreover, the anchor bolts apply a certain pressure between the vertically adjacent blocks in the wall. Thus, the anchor bolts provide constant contact between the tongues and the grooves over the entire length of the tongues. In this way, the wall is perfectly sealed.
- Moreover, the building system makes it possible for the alignment of the wall blocks to be checked and adjusted almost perfectly. By tightening an anchor bolt joining a first block to a second block to a greater or lesser extent, it is possible for the alignment and the horizontal position of the second block to be perfectly controlled. The straightness of the second block may be checked using a laser. This technique makes it possible to construct perfectly straight walls in which the position of the blocks can be individually checked.
- The building system allows the construction of walls that have to be absolutely perfectly sealed (for example for the construction of swimming pools or saunas). For this purpose, additional seals may be placed between the adjacent surfaces of the blocks and/or between the second facet of the notch and the chamfered edge of the blocks. In a preferred embodiment, these seals are made of hydrophobic rubber, for example closed-cell rubber. Rubber is an environmentally friendly material.
- The building system allows the construction of supporting walls for building components. For this purpose, certain blocks are narrower than the others, so that these blocks, placed beside one another in the wall, form a recess in the wall intended to support building components. This wall recess creates a support surface for accommodating building components such as joists for supporting a floor or rafters, purlins or ridge beams for supporting a roof. Thus, it is possible to construct dwellings easily and for a lower cost by reducing the number of parts and components to be manufactured and assembled.
- Advantageously, the blocks are made of solid wood, the system according to the invention making it possible to construct walls for dwellings serving both as interior walls and exterior walls.
- Solid wood has well-known insulation properties which make it a material of choice for constructing exterior walls. The cost of constructing such a dwelling is less since it is unnecessary to cover such a wall for the interior of the dwelling, both as regards insulation and esthetics. Moreover, by choosing bricks made from wood of different colors, it is possible to construct walls that are patterned. Alternatively, the blocks may also be made of fiber components (for example compreg wood or sealed MDF or laminated wood, etc.).
- Another object of the invention is to provide a wall that includes a part constructed using a building system according to the invention.
- Another object of the invention is to provide building blocks as used in the building system according to the invention.

-
FIG. 1 is a perspective view of an example of a wall under construction, made using the building system according to the invention. - The
wall 1 compriseswooden building blocks 2 of rectangular parallelepipedal shape, which are placed beside one another and on top of one another in a staggered fashion. The blocks are preferably made of solid wood. However, they may also be made of fiber components. The upper horizontal longitudinal face of theblocks 2 includes twogrooves blocks 2 includes twogrooves 5 c, 5 d parallel to the longest side of the face and running along the entire length of this face. Preferably, the twogrooves grooves 5 c, 5 d of the lower face. - The edge near the intersection between the upper face and the outer face of the
blocks 2 has achamfer 12. The profile of thechamfer 12 is constant and flat. It may also be rounded or of molded shape. Thechamfer 12 covers part of thefirst groove 5 b over its entire length. - A first tongue 6 a being a trapezoidal cross section includes a
rebate 60. The first tongue has afirst part 61 of substantially square cross section and asecond part 62 of substantially trapezoidal cross section connected to thefirst part 61. Therebate 60 has a first facet 62 c that rests in thefirst groove 5 a. Therebate 60 has asecond facet 62 a that rests on thechamfer 12 of thelower blocks 2 and forms a surface complementary to the profile of thechamfer 12. Since thesecond facet 62 a of the tongue 6 a is complementary to the profile of thechamfer 12, the clearance and space between these two surfaces are reduced to a minimum. A seal (not shown) may be placed between these two surfaces. Thesurface 62 b on the opposite side to thesecond facet 62 a forms a flow-off surface 62 b for water to flow away. - The
first part 61 of the first tongue 6 a is placed between thegrooves blocks 2 over the entire length of thewall 1. Thefirst part 61 of the tongue 6 a makes it possible to hold in place and to align, over the length of thewall 1, theblocks 2 placed horizontally beside one another on a given course. It also makes it possible to hold in place and align theblocks 2 placed one on top of another on two course. - When the
first part 61 of the first tongue 6 a is placed between thegrooves adjacent blocks 2, the water flow-off surface 62 of the first tongue 6 a stops on the outer vertical face of theblocks 2. The flow-off surface 62 may also extend very slightly beyond the outer vertical face of theblocks 2. The flow-off surface 62 b allows the water to be away from thewall 1, thus preventing moisture from penetrating in thewall 1. - A
second tongue 6 b is placed between thegrooves 5 b and 5 d of the blocks over the entire length of thewall 1. Thetongue 6 b reinforces the retention and alignment of theblocks 2 with respect to one another that is provided by the first tongue 6 a. -
Tongues 6 a, 6 b as long as possible, preferably with a length equal to the length of thewall 1, are used. The first andsecond tongues 6 a, 6 b may advantageously be chamfered on their edges. - It is well known to those skilled in the art that parts made of solid wood have difficulty in maintaining their original shape. The density of the wood of blocks, especially those made of solid wood, is not uniform and wood deforms under various effects, including that called “core drawing”. This phenomenon may occur in the
blocks 2 made of solid wood, and the faces of these blocks may become bowed or dished. The fact of having two grooves (5 a, 5 b) and (5 c, 5 d) per contact face between theblocks 2 provides more effective stabilization of the blocks placed one on top of another. In this way theupper blocks 2 are prevented from “pitching” or “rolling” with respect to the lower blocks 2. - Moreover, the
grooves - The
blocks 2 constituting the first course of thewall 1 are fixed to foundations in a conventional manner (not described here). The foundations may consist of a first foundation (not shown) made of concrete on which a concrete surround (not shown) rests. Theblocks 2 of the first course are fastened to this surround. - The
blocks 2 have, on each of the abutting faces, a vertical groove 7 extending between the upper and lower longitudinal faces. Tongues 8 are placed between the horizontallyadjacent blocks 2 in the grooves 7. The tongues 8 make it possible to hold in place and align the horizontallyadjacent blocks 2 in pairs. - The grooves 7 preferably have a circularly arcuate cross section, the circular arc being equal to or shorter than a semicircle. The tongues 8 of circular cross section are held in place between the grooves 7 of two horizontally
adjacent blocks 2, over the entire height of theseblocks 2. The tongues 8 are slightly compressed in the space created by the grooves 7, so as to ensure contact between the tongues 8 and each surface of the grooves 7. Thus, the wall is sealed at the abutting faces of theblocks 2. - The
blocks 2 also have, on each of the abutting faces, twovertical grooves chamfer 12. Thevertical grooves 71 closest to the outer face of the blocks form ventilation gutters between the abutting faces of the adjacent blocks. When the moisture in the air condenses on contact with the gutters, the water flows away along thegrooves 71 and then along the water flow-off surface 62 b. The moisture is thus far from the interior of thewall 1. Tongues (not shown) or seals are placed in thegrooves 72. - The
blocks 2 are fastened pairwise usinganchor bolts 14. In a preferred embodiment of the invention, eachblock 2 has fourdrill holes block 2. Ablock 2 is placed on a row ofblocks 2 already joined together. Ananchor bolt 14 is slid through the drill holes 4 a, 4 c of theblock 2 to be fastened and is screwed into twodrill holes 20 a, 20 c in one of the twoblocks 2 placed beneath. Likewise, ananchor bolt 14 is slid through the drill holes 4 b, 4 d of theblock 2 to be fastened and then screwed into twodrill holes 20 b, 20 d in theother block 2 placed beneath. By tightening theanchor bolts 14 placed in the drill holes 4 a, 4 b, 4 c, 4 d to a greater or lesser extent, it is possible to check the level of theblock 2 to be fastened, especially using a “laser leveler”. - In another embodiment (not shown), it is possible to use, in place of anchor bolts, wooden pegs, nails or any other similar means for assembling blocks.
-
FIG. 2 is a cross-sectional representation of two superposed blocks according to a preferred embodiment of the invention. - The block 2 a is placed on top of the
block 2 b in thewall 1. Theblocks 2 a and 2 b havegrooves grooves grooves 5 c, 5 d and thegrooves grooves 5 b, 5 d. - A
tongue 6 b of square cross section is kept slightly compressed in contact over the length of thewall 1 between thegrooves 5 b and 5 d of theblocks 2 b and 2 a respectively. Thefirst part 61 of a tongue 6 a of square cross section is kept in contact, slightly compressed, over the length of thewall 1 between thegrooves blocks 2 b and 2 a respectively. - The area of the cross section of the
second tongue 6 b (and of thefirst part 61 of the first tongue 6 a respectively) is equal to or slightly greater than that of the cross section of the space formed by thegrooves 5 b, 5 d (and thegrooves tongues 6 b (and thefirst part 61 of the first tongues 6 a respectively) is equal to or slightly greater than the length of the sides of thegrooves 5 b, 5 d (and 5 a, 5 c respectively). - The
tongues 6 a, 6 b, which ensure that theblocks 2 are held in place and aligned, are made of a material that is not completely rigid, such as wood, so as to be able to be compressed between thegrooves tongues 6 a, 6 b are kept compressed by theanchor bolts 14 that hold theblocks 2 a and 2 b together. There is thus a line of contact between thetongues 6 a, 6 b and each surface of thegrooves blocks 2 a, 2 b over the entire length of these grooves. In addition, thesecond part 62 of thetongue 6 b is thus kept in contact on thechamfer 12 of theblock 2 b over the length of thewall 1. - By applying this principle to all the
blocks 2 of thewall 1, a perfect acoustic, thermal and moisture seal is produced between theblocks 2 a, 2 b. - In one particular embodiment, the
tongues 6 a, 6 b may be bonded in thegrooves tongues 6 a, 6 b may be made from various materials, such as wood, rubber, plastic. - The
blocks 2 a, 2 b have, along the lower face, a groove ordrip 13 placed between the outer edge of this face and thegrooves drip 13 blocks the water that would have a tendency to run along the lower face of the block 2 a toward the interior of thewall 1. Thedrip 13 of the block 2 a is placed above the flow-off surface 62 b of the first batten 6 a. The water blocked in thedrip 13 thus drops onto the flow-off surface 62 b and runs away toward the outside of thewall 1. - A
seal 16 may be placed between the upper face and the lower face of theblocks 2 a and 2 b over the entire length of thewall 1. A seal (not shown) may also be placed between the abutting faces of the pairwise horizontallyadjacent blocks 2. The seal is made of a hydrophobic material, such as closed-cell rubber. -
FIG. 8 shows a front view of a wall constructed using the system according to the preferred embodiment of the invention. The block 2 a rests on and is fastened to theblocks 2 b usinganchor bolts drill holes drill holes 4 c and 4 d (not shown) of slightly larger diameter than that of theanchor bolts FIG. 2 ). The drill holes 4 a, 4 b, 4 c, 4 d extend vertically between the upper face and the lower face of the block 2 a and are preferably produced during manufacture of the block 2 a. - The
blocks 2 b have twodrill holes blocks 2 b. The diameter of the drill holes 20 a, 20 b, 20 c, 20 d is smaller than the diameter of theanchor bolts anchor bolts blocks 2 b, so as not to pass through these blocks. Theanchor bolts blocks 2 b so as to fasten the block 2 a to theblocks 2 b on which the block 2 a rests. The drill holes 20 a and 20 b are preferably made at the time of assembly, by using the drill holes 4 a and 4 b as guides, in order to ensure that that the drill holes 20 a and 20 b are correctly aligned with the drill holes 4 a and 4 b. The drill holes 4 a and 4 b of the block 2 a are placed in such a way as to prevent the drill holes 20 a and 20 b of theblocks 2 b from being out of alignment with the drill holes 4 a and 4 b of theblocks 2 b to which the block 2 a has to be assembled. - The
anchor bolts -
FIG. 3 shows a representation of the wall under construction in a preferred embodiment of the invention seen from above and having horizontally adjacent blocks on a given course. - The tongues preferably have a length equal to that of the
wall 1. However, for large walls (especially long ones), it may be difficult to use only asingle tongue 6 a, 6 b, as shown inFIGS. 1 and 2 . In this case, placed in thegrooves 5 a of horizontallyadjacent blocks 2 on a given course of thewall 1 are two tongues 6 a 1 and 6 a 2 butted together. Likewise,tongues 6 b 1 and 6 b 2 are placed end to end in thegrooves 5 b of horizontallyadjacent blocks 2 on one wall course. - To prevent a loss of sealing of the wall at the join between the tongues, the ends 17 c, 17 d and 17 a and 17 b of the tongues 6 a 1, 6 a 2 and 6 b 1, 6
b 2 respectively are beveled so as to form a skew joint. Moreover, the tongues 6 a 1 and 6 a 2 are assembled on adifferent block 2 and preferably one that is not adjacent to theblock 2 where thetongues 6 b 1 and 6 b 2 are assembled. Thus, even in the case of the tongues 6 a 1, 6 a 2 and 6 b 1, 6b 2 being set back, sealing is maintained at the joins of the tongues 6 a 1, 6 a 2 and 6 b 1, 6b 2. -
FIG. 4 shows a perspective representation of the wall under construction in a preferred embodiment of the invention and with a services space allowing passage of pipes or ducts. - The
grooves 5 a of horizontallyadjacent blocks 2 on one wall course constitute a services space in which a duct 9 a is placed. The duct 9 a acts as alignment and retention tongue. Theblock 2 c has a vertical hole 90 extending from thegroove 5 a. On an inner face, theblock 2 c has ahorizontal hole 91 which is connected to the vertical hole 90 and provides the link between the vertical hole 90 and the outside of thewall 1. Theholes 90 and 91 are preferably made at the time of assembling thewall 1, for example using a crown saw. - The vertical hole 90 lies between the upper face of the
block 2 c and thehorizontal hole 91. It is also possible to produce vertical holes extending over the entire height of the blocks so as to be able to connect the horizontal services spaces vertically. - The duct 9 a, if it offers the possibility of being slightly compressed, may, just like a tongue 6 a, provide a sealing function. Braces or sheaths 9 b may be placed in the
holes 90 and 91. -
FIG. 6 shows a perspective representation of the wall under construction according to another embodiment of the invention and having a services space allowing passage of pipes or ducts. - The
block 2 c has, on its upper face, a semicylindrical groove 5 e that provides the link between thegroove 5 a of theblock 2 c and the outside of thewall 1. Similarly, the block 2 a, which is intended to be assembled on top of theblock 2 c, has, on its inner surface, agroove 5 f identical to thegroove 5 b and providing the link with thegroove 5 c. -
FIG. 5 shows a perspective view of a corner formed between two walls under construction made using the system according to a preferred embodiment of the invention. - The
block 2 f of the wall 1 a is assembled in a staggered fashion with theblocks 2 h, 2 g of thewall 1 b. The corner block 2 g has an additional groove 5 e on the upper and lower surfaces. The groove 5 e is parallel to the short side of the faces. Likewise, the block 2 g has anadditional chamfer 12 b on the edge of one of the short sides of the upper surface. Thechamfer 12 b and the additional grooves 5 e allow the tongues 6 a of the wall 1 a to be placed both between the corner blocks 2 f of the wall 1 a and the corner blocks 2 g of thewall 1 b. Theinner tongues 6 b placed between the twogrooves wall 1 b. - The corner blocks 2 f, 2 g, 2 i may thus be easily stacked and held together. The tongues 6 a continue to seal the
walls 1 a, 1 b, even at the corners. -
FIG. 7 shows a perspective view of a wall having a support for building components, constructed using the system according to a preferred embodiment of the invention. - The
wall 1 has a series of horizontally adjacent half-blocks 2 n on one or more wall courses. The width of the half-blocks 2 n is half that of the other blocks of thewall 1 so as to form arecess 19 in thewall 1. Theblocks 2 m placed beneath theblocks 2 n form a bearing surface at therecess 19 on which ajoist 23 intended to support a floor rests. Therecess 19 may serve as a support for any building component such as rafters, purlins or ridge beams for supporting a roof. - The
recess 19 is filled with a set of half-blocks 2 p having a width equal to those of the half-blocks 2 n. The half-blocks joist 23 has, on each of its upper and lower faces, a groove (not shown) lying along the extension of the grooves of the half-blocks 2 p. The second battens lodged in the grooves of these half-blocks 2 b may also be lodged in the grooves of the joist. Thus, sealing is maintained at the joist; it is unnecessary to cut the second battens. Moreover, the second battens make it possible to keep thejoist 23 in place at the wall, preventing it from slipping out of therecess 19. - Returning to
FIG. 8 , thewall 1 has apocket 21 for fastening a window frame. Theblock 22 serves as lintel for the window and has a cross section identical to theother blocks 2 and of greater length than the width of the window.FIG. 9 shows a perspective view of a cross section of awall 1 at apocket 21. - Placed beneath the
lintel 22 is ablock 23 serving as opening lining for fastening a window ordoor frame support 100. Theopening lining 23, of substantially identical cross section to the cross section of theother blocks 2, is assembled and fixed to thewall 1 in the same way as theother blocks 2. Theopening lining 23 consists of three sections, preferably made of wood and joined together in a conventional manner, for example using adhesive and/or screws. Theopening lining 23 thus has anupper section 23 a of identical width to theother blocks 2 of the wall, and twolateral sections 23 c, 23 b with a rebate. The width of thelower sections 23 b, 23 c is smaller than half the width of theupper section 23 a, so as to form anopening 24 allowing insertion of theframe support 100 and acavity 25. Thewalls 24 a of theopening 24 are substantially adjacent to thewalls 100 a of theframe support 100 inserted into theopening 24. The width of thecavity 25 is greater than that of theopening 24. Theinner walls lower sections 23 b, 23 c thus form a support surface on which arail 26 rests. Therail 26 is fixed to theframe support 100, allowing assembly of theframe support 100 to theopening lining 23. - A person skilled in the art knows that wood undergoes natural compression over the course of time. The compression effect is accentuated by the pressure to which the blocks in the wall are subjected. It follows that the height of the
cavity 25 decreases over time. Theframe support 100 is therefore compressed in turn and tends to deform, making it difficult to open the doors and windows. To avoid this problem, the height of thecavity 25 is greater than the height of therail 26 so as to form a space between the upper wall of therail 26 and the lower wall of theupper section 23 a. Thelintel 22 and theopening lining 23 may deform without correspondingly deforming theframe support 100. Preferably, the height of the space (hR) is equal to the reduction in height of the cavity 25 (hC) due to the compression of the wood calculated for the height of thecavity 25. The radial shrinkage (x) of the wood is between 0.8% and 1.2%. Aseal 27 of compressible material (rubber, synthetic foam, etc.) is placed in the space between therail 26 and thesection 23 a. - The
opening lining 23 is made from threesections - In another embodiment of the invention (not shown), the
first part 61 of the first tongues 6 a and thesecond tongues 6 b have a circular cross section. The diameter of the cross section of thetongues 6 a, 6 b is equal to or slightly greater than the length of the sides of thegrooves - In another embodiment of the invention (not shown), the
blocks 2 comprise thegrooves first part 61 of the first tongues 6 a and thesecond tongues 6 b therefore have a regular hexagonal cross section equal to or slightly greater than that of thegrooves - In another embodiment of the invention (not shown), the
blocks 2 includegrooves first part 61 of the first tongues 6 a and thesecond tongues 6 b then have a circular cross section of diameter equal to or slightly greater than that of thegrooves first part 61 of the first tongues 6 a and thesecond tongues 6 b have a square cross section, the length of the side of the square being equal to or slightly greater than the diameter of thegrooves - It would be obvious to a person skilled in the art that the present invention is not limited to what has been particularly disclosed and described above. The invention lies in presenting all the novel features and in each combination of these features. The numerical references in the claims do not limit the scope of their protection. The use of the verbs “comprise, contain or include” and of their conjugated forms does not exclude the presence of components other than those innumerated in the claims. The use of the article “a or an” in front of a component does not exclude the presence of a plurality of such components.
- The present invention has been described in terms of specific embodiments that are an illustration of the invention but must not be considered to be restrictive.
