Description

Beams, system and method for assembling said beams and assembly thus formed

The field of the present invention relates to that of beams, in particular of the post or smooth type, used to make an assembly, for example a shelter, a pivoting barrier, a vegetable patch or a composter or a fence element with a grid.

The field of the present invention also relates to a system for assembling such beams, in particular at least one post with a stringer.

The field of the present invention also relates to a method for assembling such beams, in particular at least one post with a stringer, with a view to producing an assembly.

The field of the present invention finally relates to an assembly, for example a fence, a shelter, a pivoting barrier, a vegetable bed, a composter, a palisade, a safety barrier, a planter, a raised planter, a post with directional sign , a gazebo barrier, said assembly being formed by the implementation of a beam assembly system according to such a method.

It is known to use beams or pieces of wood to make sets such as, for example, a fence, a shelter, a grid, a pivoting barrier, a vegetable patch, a composter, a palisade, a security barrier, a planter , a raised planter, a post with directional sign, a gazebo barrier.

Such a set is formed by assembling the beams, or pieces, together using different techniques.

The use of screws or nails being restrictive, it is possible to use an assembly system without addition, comprising on the one hand a tenon and on the other hand a mortise which, by cooperating, allows a satisfactory assembly to produce a set. The set thus produced is aesthetically pleasing and fits well in a garden or an outdoor environment, among the trees.

However, the use of beams or pieces of wood to make an assembly with this type of assembly system comes up against several drawbacks. Thus, it is necessary to make, before sending the parts to the assembly site, cutouts of the beams and pieces of wood with precise equipment. In addition, wood requires maintenance, otherwise it degrades over time. Finally, the set made is heavy.

We are therefore looking for alternative solutions that are economical, simple to make and implement, which would allow better resistance over time and a pleasant aesthetic appearance.

An object of the invention is to provide an alternative to wooden beams, a system for assembling the beams together equivalent to the prior art, easier to use and to prepare on the assembly site, and allowing the assembly of a set simply, quickly, economically.

To this end, the subject of the invention is a beam, of the post type, in the form of a tubular body along a longitudinal axis of the post, this body comprising a peripheral outer side wall, said beam being a composite element formed by a mixture of wood and plastic material, the body of said beam being fitted internally with a central longitudinal chamber delimited by a peripheral inner side wall, connected to the outer side wall by radial walls coming from the inner side wall delimiting the the central chamber.

The production of a composite wood and plastic post improves the durability of said post. The presence of a longitudinal central chamber makes it easier to maintain the erected state of the post, the mechanical resistance to depression of which is lower than that of a wooden post.

Advantageously, the thickness of the peripheral outer side wall delimiting the body is strictly less than the thickness of the peripheral inner side wall delimiting the chamber and the thickness of the radial walls.

This arrangement makes it possible to lighten the weight of the assembly and reduce the cost of materials, while ensuring a robust and solid central internal structure.

Preferably, each radial wall of the post takes the form of a radial blade connected by one of its longitudinal edges to the peripheral inner side wall delimiting the chamber and by its other longitudinal edge to the peripheral outer side wall delimiting of said body.

The invention also relates to a beam, of the stringer type, in the form of a tubular body along a longitudinal axis of the stringer, having two opposite main faces, comprising a peripheral outer side wall, said beam being a composite element formed by a mixture of wood and plastic material, the body of said beam being provided with internal walls defining cells.

The production of a wood and plastic composite smooth improves the durability of said smooth. The presence of cells makes it possible to structurally increase the rigidity of the beam.

Advantageously, the rail is flattened in shape and has a front main face, a rear main face, an upper face and a lower face.

Advantageously, the profile of the lower face has a reservation capable of cooperating by interlocking with the profile of an upper face of another smooth.

This allows, when assembling several rails butted to each other, to reduce the gaps between the rails for a satisfactory aesthetic appearance.

The invention also relates to a system for assembling a beam of the smooth type with a beam of the post type, in accordance with those described above.

Said system comprises a longitudinal opening on all or part of the post-type beam emerging at least at one open end of said post, cooperating with a transverse inclined groove in a main face of one end of a beam forming a smooth.

Advantageously, the longitudinal slot on all or part of the post-type beam is opened transversely by an angle of between 40 and 50 degrees, measured from the longitudinal axis of the post.

Advantageously, the longitudinal slot is placed against a radial blade, leaving a free part of the peripheral outer side wall.

The assembly is thus more robust.

Advantageously, the width of the groove is equal to 1.3 times the thickness of the peripheral outer side wall of the corresponding post.

Advantageously, the groove is inclined relative to the rail at an angle of 45 degrees, to within 5 degrees.

Advantageously, the end of the heddle comprising the groove has, on its main face opposite the groove, a fillet on its end, the groove and the fillet delimiting an end lug whose thickness is less than the radial spacing between the peripheral inner side wall and the peripheral outer side wall. This end lug of the stringer is able to be housed between the peripheral inner side wall and the peripheral outer side wall of the post.

Such an assembly system is simple and robust.

The invention also relates to a method for assembling a beam of the smooth type with a beam of the post type, in accordance with those described above, using an assembly system described above, and comprising the following steps:
– we select a beam forming a column open at one end,
– a beam forming a smooth is selected,
– a longitudinal light is cut on all or part of the post opening out at least at one open end of the said post, so that the light is leaning against a radial blade, and forming a free part of the peripheral outer side wall of the post,
– a transverse groove is made in one end of a smooth beam,
– the stringer is assembled to the post by sliding the stringer into the open end of the post, the part of the peripheral outer side free wall of the post engaging in the groove of the stringer.

The assembly thus produced is robust and this assembly system can be made quickly on the assembly site with portable equipment, such as a battery-powered circular saw, using posts and stringers as described above.

The particular sections of the post and the stringer allow this assembly to be carried out simply.

Advantageously, according to this method, posts are assembled with rails to form all or part of an assembly such as, for example, a shelter, a pivoting barrier, a vegetable patch, a composter, a palisade, a security barrier, a planter, raised planter, post with directional sign, gazebo gate.

The invention also relates to a system for assembling a beam of the smooth type with a beam of the post type, in accordance with those described above and with a grid formed from a welded mesh of vertical and horizontal metal rods, to form a closing element.

Said system comprises a longitudinal opening on all or part of the post-type beam opening at least at one open end of said post, a longitudinal opening in a beam forming a smooth opening at least at one end of said smooth, and an orifice in the post adapted to receive a smooth end; said orifice being crossed by the longitudinal slot, the longitudinal slot and the longitudinal opening being designed to receive the grid.

Advantageously, the longitudinal slot of the post is made through only the peripheral outer side wall of the post.

Advantageously, the spacing of the longitudinal light of the post is greater than the thickness of the vertical rods of the grid and less than the combined thickness of the horizontal and vertical rods.

Advantageously, the longitudinal opening of the rail is made through only the outer peripheral side wall of the rail.

Advantageously, the spacing between the edges of the longitudinal opening of the rail is greater than the thickness of the horizontal rods of the grid and less than the combined thickness of the horizontal and vertical rods.

Thus, this assembly system makes it possible to have a vertical rod of the grid in a post, a horizontal rod of the grid in a rail, and the rail engaged in the post. Such an assembly system is simple and robust.

The invention also relates to a method of assembling a beam of the smooth type with a beam of the post type and with a grid formed from a welded mesh of vertical and horizontal metal rods to form a fence element using a system of fence element assembly described above, and comprising the following steps:
– we select a beam forming a column, having at least one open end,
– a beam forming a smooth is selected,
– we select a grid formed of a welded mesh of vertical and horizontal metal rods,
– a longitudinal opening is cut on all or part of the post opening out at least at one open end of the said post,
– a longitudinal opening is cut in a beam forming a smooth opening at least at one end of said smooth,
– a hole is cut in the post suitable for receiving one end of the rail, said hole being crossed by the longitudinal slot,
- the grid is assembled to the post by sliding a vertical rod on a vertical edge of the grid in the post by one end from which the longitudinal slot emerges, the grid extending through the longitudinal slot of the post,
– the rail is assembled to the post and to the grid by sliding a horizontal rod on a horizontal edge of the grid in the rail by one end from which the longitudinal opening emerges, the grid extending through the longitudinal opening smooth,
- the end of the rail is slid over the grid until it engages in the hole in the post.

The assembly thus produced is robust and this assembly system can be made quickly on the assembly site with portable equipment, such as a battery-powered circular saw, using posts and stringers as described above.

The particular sections of the post and the stringer allow this assembly to be carried out simply.

Other aims and advantages of the present invention will appear during the description which will follow relating to embodiments which are given only by way of indicative and non-limiting examples.

The invention relates to a beam of the post type 1 hereinafter referred to by the general term "post" 1 and a beam of the smooth type 2 hereinafter referred to by the general term "smooth" 2. The invention also relates to a system of assembly 3 of a post 1 with a smooth 2 and a corresponding assembly method. The invention further relates to another assembly system 4 of a post 1 with a rail 2 and a grid 5 to form a fence element, as well as a corresponding assembly method to form a fence element.

For the entire description, the invention is considered with posts 1 arranged in a position of use, that is to say vertically, stringers arranged in a position of use, that is to say horizontally. Similarly, grids 5 are arranged in a position of use, that is to say vertically.

Thus, the posts 1 have a high end and a low end.

Of course, the positions of use presented above are only indicative and not limiting. A post 1 can also be used horizontally and a rail 2 vertically, or both tilted with respect to the ground.

A post 1 according to the invention is in the form of a tubular body along a longitudinal axis OO′ of the post 1. This body comprises a peripheral outer side wall 10. The term lateral denotes the side of the body when post 1 is vertical. The body is internally provided with a longitudinal central chamber V0, delimited by a peripheral inner side wall 11. The peripheral outer side wall 10 is connected to the peripheral inner side wall 11 by radial walls 12. These radial walls 12 come from and integral with the peripheral outer side wall 10 and also the peripheral inner side wall 11, as illustrated in particular in Figures 1 and 3.

The radial walls 12, the peripheral outer side wall 10 and the peripheral inner side wall 11 define an intermediate chamber 13. Here, due to four radial walls, there are four intermediate chambers, as illustrated in particular on the .

In fact, the post 1 can also be defined as comprising two coaxial tubular walls along the longitudinal axis OO' of the post 1, internal 10 and external 11, connected by radial walls 12, defining a central chamber V0 and intermediate chambers 13 .

Post 1 has at least one open end, as shown in .

The presence of a longitudinal central chamber V0 makes it possible to maintain a mechanical resistance of the post 1, even if an intermediate chamber 13 is open on its peripheral outer side wall 10. This also increases the mechanical resistance in compression of the post 1 compared to a post wood of the same dimensions.

Another characteristic of this post type beam 1 is that it is a composite element formed by a mixture of wood and plastic material.

Indeed, a pole 1 composite wood and plastic has improved durability over time of said post 1, compared with a wooden post.

Another characteristic of this post-type beam 1 is that the thickness of the peripheral outer side wall 10 delimiting the body is strictly less than the thickness of the peripheral inner side wall 11 delimiting the chamber and the thickness radial walls 12.

This arrangement makes it possible to lighten the weight of the assembly and reduce the material cost, while ensuring a robust and solid central internal structure, all the more so if an intermediate chamber is open on its peripheral external side wall 10.

Each radial wall 12 of post 1 takes the form of a blade connected by one of its longitudinal edges to the peripheral inner side wall 11 delimiting the central chamber V0 and by its other longitudinal edge to the peripheral outer side wall 10 delimitation of said body.

The beam of the smooth type 2 is itself in the form of a tubular body along a longitudinal axis AA' of the smooth 2. This smooth 2 has two opposite main faces FP1 and FP2. This smooth 2 comprises a peripheral external side wall 20 and is provided with internal walls 21 defining cells 22. These internal walls 21 are produced and formed in one piece with the peripheral external side wall 20, as illustrated in particular on the .

Each smooth-type beam 2 is a composite element formed by a mixture of wood and plastic material, just like the post-type beams above.

The production of a wood and plastic composite smooth 2 makes it possible to improve the durability of said smooth 2 over time. The presence of cells 22 makes it possible to structurally increase the rigidity of the smooth 2, even if a cell 22 is open on its peripheral outer side wall 20.

As illustrated on the , the smooth 2 is flattened in shape and has, in a vertical usage configuration, a main front face FP1, a main rear face FP2, an upper face FS and a lower face FI. The main front face FP1 advantageously has a curved shape reminiscent of the shape of a side part of a log. This main front face FP1 is designed to be visible because it faces the outside of a construction element using this smooth 2, as described below.

The profile of the lower face FI of a smooth 2 here has a reservation capable of cooperating by interlocking with the profile of an upper face FS of another smooth 2 which would be arranged below, upper face FS upwards.

This makes it possible, when assembling several healds abutting each other, to reduce the gaps between the healds 2 for a satisfactory aesthetic appearance.

Each internal wall 21 of the heddle 2 takes the form of a blade connected by its longitudinal edges to the peripheral external side wall 20 delimiting said body.

Another characteristic is that the body of one or other of the beams, post 1 or stringer 2, described above is an extruded body. This results in simplicity of manufacture.

Another characteristic is that the walls of the body of one or other of the beams, post 1 or smooth 2, described above are made in one piece, preferably monolithic.

Preferably but optionally, the wood is present in one or other of the beams, post 1 or smooth 2, described above in the form of micronized wood fiber and represents at most 70% by weight of the total weight of said body beams.

This optimizes the mechanical reinforcement of the composite thus created.

Preferably but optionally, the plastic material used is chosen from the group of polyolefins and is preferably formed by High Density Polyethylene (HDPE).

We will now describe an assembly system 3 according to the invention of a beam of the smooth type 2 with a beam of the post type 1, in accordance with those described above.

Said assembly system 3 comprises a longitudinal slot 31 along the longitudinal axis OO' of the post 1 which can be on all or part of the post-type beam 1. This longitudinal slot 31 opens at least at one end of the said post 1.

This slot 31 of post 1 cooperates with a transversely inclined groove 32 in a main face, preferably front FP1, of one end of a beam forming a smooth 2.

The longitudinal slot 31 of the post 1 is made through only the peripheral outer side wall 10 of the post 1.

In fact, this longitudinal opening 31 of the post 1 opens into an intermediate chamber 13 of the post 1. Part of the end of the heddle 2 is therefore found in an intermediate chamber 13 of the post 1, as illustrated in the .

The longitudinal slot 31 is opened transversely by an angle of between 40 and 50 degrees, measured from the longitudinal axis OO' of the post 1.

The longitudinal slot 31 is leaning against a wall or radial blade 12, leaving a free part 103 of the peripheral external side wall 10, as illustrated in the . This free part 103 engages in the groove 32. The assembly is thus more robust.

The width of the groove 32 of the smooth 2, that is to say the spacing between the edges of the groove 32, is equal to 1.3 times the thickness of the peripheral outer side wall 10 of the post 1 corresponding . This value can be greater or less depending on the play you want to leave in the assembly, but this value makes it possible to obtain a particularly robust assembly.

The groove 32 of the rail 2 is inclined with respect to the rail 2 at an angle of 45 degrees, to within 5 degrees.

In order to have an even more robust assembly, the end of the smooth 2 comprising the groove 32 has, on its main face FP2 opposite the groove 32, a fillet 33 on its end, as illustrated in the .

The groove 32 and the fillet 33 delimit an end lug 34 whose thickness is less than the dimensions of the intermediate chamber 13, more precisely than the radial spacing between the peripheral internal side wall 11 and the peripheral external side wall 10 of the post 1. This end lug 34 of the rail 2 is able to be housed in an intermediate chamber 13, between the peripheral internal side wall 11 and the peripheral external side wall 10 of the post 1.

Such an assembly system is then simple and robust.

Such an assembly system described above can be used in an assembly method according to the invention of a beam of the smooth type with a beam of the post type, in accordance with those described above. This process comprises the following steps:
– we select a beam forming column 1, open at one end; this beam 1 can be cut to the desired size,
– a beam forming a smooth 2 is selected; this beam 2 can be cut to the desired size,
– a longitudinal slot 31 is cut on all or part of the post 1 opening out at least at one open end of the said post 1, so that the slot 31 is leaning against a radial blade 12 of the said post 1, and forming a free part 103 peripheral outer side wall 10 of post 1,
– a transverse groove 32 is made in one end of a beam forming a smooth 2,
– the rail 2 is assembled to the post 1 by sliding the rail 2 into the open end of the post 1, the free part 103 of the peripheral outer side wall 10 of the post 1 engaging in the groove 32 of the rail 2.

The assembly thus produced is robust and this assembly system 3 can be made quickly on the assembly site with portable equipment, such as a battery-powered circular saw, using posts 1 and smooths 2 as described above.

The particular sections of the post 1 and the rail 2 allow this assembly to be carried out simply.

According to an additional intermediate step of the method presented above, a fillet 33 is formed on the end of the smooth 2 comprising the groove 32, on the corner opposite the groove 32, so that the groove 32 and the fillet 33 delimit an end lug 34 whose thickness is less than the radial spacing between the peripheral inner side wall 11 and the peripheral outer side wall 10.

The assembly is even more robust and this assembly system 3 can always be carried out simply on the assembly site with portable equipment, such as a battery-powered circular saw.

Several heddles 2 can be slid successively into the open end of post 1 to form a surface formed by several heddles 2 butted together. This simply forms a panel.

The upper surfaces FS and lower FI of the healds 2 fit together to limit the gaps between the healds 2 to present on the front face a rendering of a stack of logs.

It is possible to assemble according to this process posts 1 with smooth 2 to form all or part of an assembly, such as for example a shelter as illustrated in the , a swing gate, a vegetable bed as shown in the or a composter as shown in the . You can also form a palisade, a security barrier, a planter, a raised planter, posts with directional signs, a gazebo barrier. These examples are of course not limiting.

The assembly is even more robust and this assembly system 3 can always be carried out simply on the assembly site with portable equipment, such as a battery-powered circular saw.

The assembly of the posts 1 with the heddles 2 can of course be completed by other complementary assembly systems and methods comprising additional metal assembly elements, caps for covering the ends of the posts or heddles, or means fastening such as for example screws.

We will now describe an assembly system 4 according to the invention of a beam of the smooth type 2 with a beam of the post type 1, in accordance with those described above, and with a grid 5 formed of a welded mesh of vertical and horizontal metal rods. This assembly system 4 makes it possible to form a fence element.

Said assembly system 4 comprises a longitudinal slot 41, as illustrated in the , on all or part of the post-type beam 1 opening at least at one open end of said post 1, a longitudinal opening 42 in a beam forming a smooth 2 opening at least at one end of said smooth 2, and an orifice 43 in the post 1 capable of receiving one end of heddle 2; said orifice 43 being crossed by the longitudinal slot 41, the longitudinal slot 41 and the longitudinal opening 42 being designed capable of receiving the grid 5.

The longitudinal slot 41 of the post 1 is made through only the peripheral outer side wall 10 of the post 1 to open into an intermediate chamber 13.

The spacing of the longitudinal slot 41 of the post 1 is greater than the thickness of the vertical rods of the grid 5 and less than the combined thickness of the horizontal and vertical rods of the said grid 5.

The longitudinal opening 42 of the rail 2 is made through only the peripheral outer side wall 20 of the rail 2 to open into a cell 22.

In fact, the spacing between the edges of the longitudinal opening 42 of the smooth 2 is greater than the thickness of the horizontal rods of the grid 5 and less than the combined thickness of the horizontal and vertical rods.

Thus, this assembly system 4 makes it possible to have a vertical rod of the grid 5 in a post 1, a horizontal rod of the grid 5 in a smooth 2, and the smooth 2 engaged in the post 1. Such a system of Assembly 4 is simple and robust.

Such an assembly system 4 to form a fence element described above can be used in a method of assembling a fence element according to the invention of a beam of the smooth type 2 with a beam of the post type 1 , consistent with those described above. This process comprises the following steps:
– a beam forming a column 1, having an open end, is selected; this beam 1 can be cut to the desired size,
– a beam forming a smooth 2 is selected; this beam 2 can be cut to the desired size,
– we select a grid 5 formed of a welded mesh of vertical and horizontal metal rods,
– a longitudinal opening 41 is cut on all or part of the post 1 opening out at least at one open end of said post 1,
– a longitudinal opening 42 is cut in a beam forming a smooth 2 opening out at least at one end of said smooth 2,
– an orifice 43 is cut in the post 1 capable of receiving one end of the heald 2, said orifice 43 being crossed by the longitudinal slot 41 of the post 1,
- the grid 5 is assembled to the post 1 by sliding a vertical rod on a vertical edge of the grid 5 in the post 1 by one end from which the longitudinal slot 41 emerges, the grid 5 extending through the longitudinal slot 41 of post 1. This step is illustrated by the ,
– the smooth 2 is assembled to the post 1 and to the grid 5 by sliding a horizontal rod on a horizontal edge of the grid 5 in the smooth 2 by one end from which the longitudinal opening 42 emerges, the grid 5 s' extending through the longitudinal opening 42 of the stringer 2,
- the end of the rail 2 is slid over the upper edge here of the grid 5 until it engages in the orifice 43 of the post 1. This step is illustrated by the .

The assembly thus produced is robust and this assembly system 4 can be made quickly on the assembly site with portable equipment, such as a battery-powered circular saw, using posts and stringers as described above.

The particular sections of the post 1 and the rail 2 allow this assembly to be carried out simply.

It is possible to assemble according to this method two posts 1 with a smooth 2 and a grid 5 to form a fence element comprising a grid 5 attached on each side to posts 1 and above to a smooth 2, as illustrated on the .

But alternatively, one can assemble according to this method two posts 1 with two smooth 2 and a grid 5 to form a fence element comprising a grid 5 attached on each side to posts 1 and above and below to a smooth 2.

The assembly is even more robust and this assembly system 4 can always be carried out simply on the assembly site with portable equipment, such as a battery-powered circular saw.

The assembly of the posts 1 with the rails 2 and a grid 5 can of course be completed by other complementary assembly systems and methods comprising additional metal assembly elements, caps for covering the ends of the posts 1 or heddles 2, or fastening means such as for example screws.

The assembly method and the method for assembling a fence element described above according to the invention can be implemented by using respectively an assembly system 3 or an assembly system 4 of an element closing having all or some of the characteristics described above.

An assembly system 3 or an assembly system 4 of a fence element described above according to the invention can be used to respectively carry out a method of assembly and a method of assembly of a fence element described above.
