Description

Union system for the mechanical union of construction elements.

FIELD OF THE INVENTION

The invention corresponds to a joining system for the mechanical joining of at least two construction elements.

BACKGROUND OF THE INVENTION

Numerous joining systems are known in the joint technique, for example for joining construction elements, such as natural or artificial stones and wood or metal supports.

In the construction of houses, load-bearing walls are often constructed of bricks, which are joined with cement mortar. The result is a rigidly bonded wall, which is relatively inelastic. The stiffness of the joint makes walls of this type susceptible to vibrations and shocks, for example from an earthquake.

The construction of brick walls with mortar comprises, in addition to stacking the bricks, a mortar preparation stage, a mortar application stage on the brick, and a mortar setting stage, during which the bonding of the bricks is formed. building elements. The mortar application stage must be carried out within a certain period of time, after the mortar is manufactured, before the mortar begins to set. The stacking of the bricks is limited to a certain number of rows, before other rows of bricks can be stacked on the bricks that are joined by hardened mortar. This causes delays due to pauses during the work.

The environmental conditions also limit the preparation of the mortar, for example, the typical cement mortar preparation temperature is above 5 ° C. At temperatures below 0 ° C the problem arises that the water that is commonly used for the preparation of the mortar is frozen.

The placement of individual bricks is determined by positioning during application. Therefore, to achieve an exact wall, a certain professional skill is necessary and expensive and trained workforce is required.

The construction elements for interior walls and / or that do not support load are joined today frequently by means of adhesive. The same limitations as discussed above in relation to the preparation of the mortar are valid for the preparation of the adhesive.

Mainly in the field of DIY there are a series of systems for interior walls with positioning devices, which thus help to position the building elements relatively closely. Positioning devices of this type, for example the key and tongue systems, must be placed in the construction elements during their manufacture. At the construction site, the completely shaped construction elements can be fitted together and joined, for example, by adhesive.

Adhesive joints of building elements are known, for example, in the field of wood joints. Several different tongue and groove joints are known, for example in the field of joinery, so for example the dovetail-shaped junction allows the joining, fitting together, of two construction elements.

Similarly, the use of adhesive-free spike joints for wooden construction elements is known. German patent DE 1 107 910 shows a connection between two construction elements, which is produced through a flexible spike. The flexible pin is inserted in two construction elements, in two holes. The axes of the holes are inclined slightly with respect to the normal surface of the building element. When the construction elements are compressed, the holes of the construction elements form an obtuse angle and the spike bends obeying that obtuse angle. Preferably, two or more spikes are used. In adjacent construction elements, the inclination of the axis of the hole with respect to the surface points in a direction other than the inclination of the corresponding axis of the hole in the adjacent construction element. The experience of the ‘910 patent is limited to wood and wood type materials. The ‘910 patent deals especially with the problem of the inclusion of air between the spike and the hole, which in the event of a rise in ambient temperature can lead to an explosive breakage of the joint due to the expansion of that enclosed air. The ‘910 patent describes a method of how this bonding solution can be avoided by milling the spike.

Screw type joint systems can be used universally. A problem with fixing systems of this type is the accessibility of the screw head and the nut, for example when more than one row of construction elements such as construction stones are coupled, in order to form a wall. After fixing the row, the lower face of a building stone can no longer be easily accessed. Another problem is the accidental loosening of screw type joints. When the wall is finished, it is no longer possible to access the screws that are inserted along the construction direction of the wall.

Problems with the accessibility of the screw and nut head, and the possible positions for the screws, have led to solutions such as those described in European patent application EP-A-1 389 687. The application '687 It shows a system for mechanical joining of construction elements, in which special joining elements are placed in the construction elements. The connecting elements are fixed on the construction elements by screws, before the construction elements are coupled. In the assembly of the construction elements, the joining elements provide a gear, such that after the coupling of the construction elements it is almost impossible to disassemble the construction elements without having to destroy them. As described in German patent DE-A-100 266 769, these systems can be used in the construction of prefabricated houses. The ‘769 patent shows the use of said joining elements for constructions with a useful life not only long, but also medium, for example for emergency shelters after earthquakes, or military constructions. The patent memory emphasizes the advantages with respect to construction times, costs and the possibilities of building houses only with low-skilled workers, as opposed to methods such as building brick walls using mortar.

The drawback of the systems described in the ‘769 and‘ 687 patents is that both auxiliary joining elements are added to the construction elements. By themselves, these joining elements are rather difficult to build.

In another approach for a mortar-free method for the construction of brick walls, a screw type joint system is shown as a construction system, as described in European patent application EP-A1 382 761. Starting from problems Similar to those of the '769 patent, the' 761 application shows a joining system in which, starting from a base plate, the individual bricks are joined by screws with the row of upper and lower bricks. In one embodiment, the upper fasteners have a lower female thread. The lower fasteners begin at the base plate and have a length of approximately the height of the brick, and have an upper male thread. The bricks have holes that are adapted to the lower fixing elements of the fixing system. When stacking a row, the lower fasteners are guided through the holes in the bricks. The upper fixing elements are screwed to the lower fixing elements. The upper part of the upper fixing element is constructed in such a way that it can serve as a lower fixing element for the next row. Application ‘761 describes a system that allows the disassembly and new non-destructive assembly of the construction elements. In preferred embodiments, the ‘761 application describes positioning devices to keep the bricks in the right place. The application ‘761 is oriented to brick walls for facades in houses with wooden structure. No data are given on the load capacity of the walls.

In the German patent application brochure DE 34 44 465 A1 a gear pin is shown, in which a gear chamber is incorporated. In the gear chamber there is a double threaded toothed crown, at which end an expansion pin is respectively attached. The gear pin works according to the principle of a tightening screw and thus can firmly hold an object together, and release it again.

OBJECTIVE OF THE INVENTION

It is therefore objective of the invention to provide a stable joining system, usable in many ways, for various types of construction elements.

It is another object of the invention to make possible a union of construction elements, which enables an elastic movement of the construction elements with each other.

It is another object of the invention to provide a bonding system that enables efficient construction of buildings such as houses, even under adverse environmental conditions.

These objectives are achieved through the provision of a joint system for fixing a first construction element to a second construction element. The joining system comprises a first pin, with a first inner hole of the pin, and with a first inner hole axis of the pin, which is inserted into a first construction element, being able to be fixed in a first hole with a first shaft of the hole, and a second pin with a second inner hole of the pin, and with a second axis of inner hole of the pin, which is introduced into a second construction element and can be fixed in a second hole with a second axis of the hole. The inner hole of the pin of the first pin and the second pin respectively has an inner hole of the upper pin in the upper part of the pin, with an inner hole radius of the upper pin, and an inner hole shaft of the top pin, and an inner hole of the bottom pin in the bottom of the pin, with an inner hole radius of the bottom pin, and an inner hole shaft of the bottom pin. The radius of the inner hole of the upper spike is larger than the radius of the inner hole of the lower spike. The shaft of the inner hole of the pin of the first upper part of the pin and the axis of the inner hole of the pin of the first lower part of the pin, as well as the axis of the inner hole of the pin of the pin of the second upper part of the pin and the shaft of the inner hole of the pin of the second lower part of the pin are not coaxially shaped, in order to block the entire joint system with the construction elements, in which the bushing and the plug they deform and compress against the corresponding wall of the spike. A bushing with an inner and outer bushing radius is fixed between the pins in the first inner hole of the pin and in the second inner hole of the pin. A plug with a radius of the plug is fixed in the socket. The plug can be fixed between the pins in the first and second inner bottom hole of the pin.

The use of a joint system according to the invention makes it possible to join building elements of a large number of types of materials, which allow sufficiently stable holes. The materials for the spike, the bushing and the plug can be adapted in its structure, for example to the structure of its surface. The materials for the spike, the bushing and the plug can also be adapted in their properties, for example, to the elasticity of the materials of which the building elements are composed. Typical diameter

10 of the holes is in an area that allows efficient drilling of holes in the materials of the building elements.

The movement of the constructive elements joined together with respect to each other is determined primarily through the elastic properties of the joint, since the union between the constructive elements through the joint systems occurs only at certain points, as well as additionally by

15 friction forces between the joined construction elements. In particular, the elastic properties of these joints can be adjusted, in relation to the materials used for the joint systems. In this way it is possible to construct a non-rigid wall, especially suitable for buildings in seismic environments.

Build with the published bonding system is independent of the ambient temperature. The constructive elements can be provided with the drills before transport to the construction site, or

20 directly at the construction site. The assembly of the construction elements can be done by unskilled labor. Waiting time for mortar hardening is eliminated.

The connection can be formed, for example, by bending the plug and the bushing at an obtuse angle. The elastic forces and the resulting plastic deformations in the joint system mesh the joint system with the construction elements.

The joint originates through the deformation of the bushing and the pin by means of an eccentricity of an axis of the hole of the upper pin with respect to an axis of the hole of the lower pin. In this way the bushing and the plug are pressed against the wall of the spike, and fix the entire system of union with the construction elements.

The union is formed through deformations and torsions that are formed through the mismatch of the axes

30 of the inner pin hole of a first pin installed with respect to the axes of the inner pin hole of a second pin.

The joint can be formed through deformations and torsions, which occur, for example, through the compression of the bushing, pin and pin together, for example by recessing the plug into an inner hole of the cone-shaped spike , when, for example, the plug has a diameter greater than the inner hole of the

35 spike that runs conically, to its corresponding embedment depth.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a connection system 10 of the disassembled invention. A first constructive element 20 has to be joined with a second constructive element 30. The first constructive element 20 and the second constructive element 30 may be of any material, including, but not limited to, stone, brick, concrete or wood. A first hole 40 is drilled in the first constructive element 20 and a second hole 50 is drilled in the second constructive element 30. A first pin 60 is inserted into the first hole 40 and a second pin 70 is inserted into the second hole 50. The first pin 60 has a first hole 80 inside the pin and the second pin 70 has a second hole 90 inside the spike.

In advantageous embodiments of the invention, the first pin 60 and the second pin 70 are subdivided into two zones. The first pin 60 has a first upper part 62 of the pin and a first lower part 64 of the pin. The first upper part 62 of the pin is coupled to the surface of the first constructive element 20 and the first lower part 64 of the pin is inside the first constructive element 20. The first upper part 62 of the spike and the first lower part 64 of the spike are joined by an intermediate piece 66, which runs in a conical shape. The diameter of the inner hole of the pin of the first upper part 62 of the pin is larger than the diameter of the inner hole of the pin of the first lower part 64 of the pin.

Similarly, the second pin 70 has a second upper part 72 of the pin and a second lower part 74 of the pin. The second upper part 72 of the tang engages the surface of the second constructive element 30 and the second lower portion 74 of the tang is inside the second constructive element 30. The second upper part 72 of the spike and the second lower part 74 of the spike are joined by an intermediate piece 76, which runs in a conical shape. The diameter of the inner hole of the spike of the second upper part 72 of the spike is larger than the diameter of the inner hole of the spike of the second bottom part 74 of the spike.

The length of the upper first part 62 of the shank and the upper second part 72 of the shank are basically the same and are described in Figure 1 by a D. The depth of the first hole 40 and the second hole 50 are also basically the same and are described by a C.

A bushing 100 is inserted into the first inner hole 80 of the pin to a depth of about 1 / 3D, and a pin 110 is inserted into the second hole 50. The bushing 100 is typically shaped as a hollow cylinder. Pin 110 may be shaped, for example, as a hollow cylinder or a solid cylinder.

In an embodiment of the invention, by way of example, the first constructive element 20 and the second constructive element 30 are concrete slabs. The first pin 60 and the second pin 70 are made of synthetic material, or of silicate polymer. In a plastic, such as polyethylene, for example, silicate particles can also be added in order to form a silicate reinforcement. The first pin 60 and the second pin 70 may be provided with a ceramic coating, for improved bonding. By means of this ceramic coating, or reinforcement with silicates, the friction between the respective construction elements 20 and 30, the respective pins 60 and 70 and the respective bushing 100 and the respective plug can be increased, for example.

110.

The upper first part 62 of the shank and the second upper part 72 of the shank have a length of 120 mm., An internal bore diameter of the shank of 25.8 mm. and an outer diameter of the spike of 49.6 mm. The lower first part 64 of the spike and the lower second part 74 of the spike are 80 mm long, with an internal bore diameter of the spike of 20.2 mm. and an outer diameter of the spike of 49.6 mm. Pin 110 is made of St37 steel, with a length of 398 mm. and a diameter of 19 mm. The first hole 40 and the second hole 50 have a hole diameter of 50 mm. and a depth of 200 mm. The bushing 100 is made of St37 steel, with an inner diameter of the bushing of 19.8 mm., An outer diameter of the bushing of 25 mm. and a length of 238 mm. This sizing is only by way of example, and the invention is not limited by these dimensions.

In an embodiment of the invention, the first pin 60 and the second pin 70 are made in one piece. In another embodiment of the invention, the first pin 60 and the second pin 70 are made of two respective pieces, corresponding to the upper parts 62 and 72 of the pin and the lower parts 64 and 74 of the pin. The spike formed by two parts is eventually easier to produce from the point of view of manufacturing.

Figure 2a shows another embodiment of the invention, in which both the first pin 60 and the second pin 70 are formed in two parts. In this embodiment of the invention, the first pin 60 is divided into a first upper part 62 of the pin with a first upper inner hole 82 of the pin and a lower first part 64 of the pin with a first lower inner hole 84 of the spike, and the first top part 62 of the spike and the first bottom part 64 of the spike are respectively formed as a single piece. Similarly, the second pin 70 is divided into a second upper part 72 of the pin with a second upper inner hole 92 of the pin and a second lower portion 74 of the pin with a second lower inner hole 94 of the pin, and the second upper part 72 of the spike and the second lower part 74 of the spike are respectively formed as a single piece. The first upper part 62 of the spike and the second upper part 72 of the spike are respectively 54 mm. long, with an outer diameter of 44 mm. and a diameter of the inner hole of the spike of 21.5 mm. The first bottom part 64 of the spike and the second bottom part 74 of the spike are respectively 36 mm. long, with an outer diameter of 44 mm. and a diameter of the inner hole of the spike of 18 mm. The inner hole 82 of the pin of the first upper part 62 of the pin and the inner hole 84 of the pin of the first lower part 64 of the pin are not coaxial in this embodiment of the invention, that is, the shaft 63 of the inner pin hole of the first upper part 62 of the pin and the shaft 65 of the inner hole of the pin of the lower first part 64 of the pin are offset relative to each other, and the shaft 63 of the inner hole of the pin of the first upper part 62 of the pin and the shaft 65 of the inner hole of the pin of the first lower part 64 of the pin are eccentric. Similarly, the inner hole 92 of the pin of the second upper part 72 of the pin and inner hole 94 of the pin of the second lower part 74 of the pin are not coaxial in this embodiment, that is to say that the shaft 73 of the inner pin hole of the second upper part 72 of the pin and the shaft 75 of the inner hole of the pin of the second bottom part 74 of the pin are offset with respect to each other and that the axes 73, 75 of the inner hole of the spike are eccentric. For example, the shaft 63 of the inner pin hole of the first upper part 62 of the pin and the shaft 73 of the inner pin hole of the second upper part 72 of the pin, as well as the shaft 65 of the inner hole of the pin of the first bottom part 64 of the pin and the shaft 75 of the inner hole of the pin of the second bottom part 74 of the pin may be offset about 1 mm. with respect to the corresponding shafts of the tang of the piece, which coincide with the shafts of the drills. The first upper part 62 of the spindle is rotated with respect to the first lower part 64 of the spike, just as the upper second part 72 is rotated with respect to the second lower part 74, then rotated with each other in 15 ° in the first bore 40, or in the second hole 50., for joining with the eccentricities. The eccentricities of the first pin 60 can then be additionally rotated with respect to the eccentricities of the second pin 70. For the material of the first pin 60 and the second pin 70, polyethylene can be used, with about 8 , 9 percent by weight silicate particles. The connection system 10 is formed together with a pin 110 made of steel, with a length of 180 mm. and a diameter of 18 mm., and a steel bushing 100 with an inner diameter of bushing of 18 mm., an outer diameter of bushing of 21.5 mm., and a length of 108 mm.

In Figure 2b, the upper part 230 of the pin, which is equivalent to the upper parts 62, 72 of the pin of Figure 2a, is uniquely represented for the first or second pin. In Figure 2c, the bottom part 220 of the pin, which is equivalent to the bottom parts 64, 74 of the pin of Figure 2a, is uniquely represented for the first or second pin. In the embodiment shown, the lower part 220 of the pin is provided with springs 232, which can fit into the slots 222 of the upper part 230 of the pin, and thus prevent the upper part 230 of the pin from rotating with respect to the bottom 220 of the spike.

Figure 3 shows the connection system 10 of Figure 1 assembled. Pin 110 is completely fitted to bushing 100. Pin 110 and bushing 100 are held in this position by force (F), which is exerted on bushing 100 by the first pin 60 and the second pin 70 .

Figure 4 shows an embodiment of the invention, whereby the shaft 63 of the inner hole of the pin of the upper first part 62 of the pin and the shaft 65 of the inner hole of the pin of the first lower part 64 of the pin, as well as the axis 73 of the inner hole of the pin of the second upper part 72 of the pin and the axis 75 of the inner hole of the pin of the second lower part 75 of the pin, are not coaxially shaped.

Other embodiments of the joint system are shown in Figures 5-7. These use as material for the first pin 60 and for the second pin 70 polyethylene with about 8.9 percent by weight silicate particles. Pin 110 (shown as an example separately in Figure 9), is made of steel with a length of 180 mm, and a diameter of 18 mm. The bushing 100 (shown as an example separately in Figure 8), is made of steel with an inner diameter of 18 mm., An external diameter of 21.5 mm., And a length of 108 mm. The first pin 60 and the second pin 70 respectively comprise an upper part 62, 72 of the pin and a lower part 64, 74 of the pin. The first bottom part 64 of the spike and the second bottom part 74 of the spike comprise, respectively, hooks 240. The hooks 240, for example 3 mm thick, 6 mm. wide in profile, with a length of 33 mm., they can protrude from the lower first part 64 of the spike and from the second lower part 74 of the spike. For this fixing system 10, however, there are several configurations of the first pin 60 and the second pin

70:

1st. Example (figure 5): The upper part 230 of the spike has a length of 55 mm., A diameter 250 of the inner hole of the spike, conical decreasing from 24 mm. at 21.5 mm, which then remains for another length of 11 mm. with a constant value of 21.5 mm., and an outer diameter of the spike of 44 mm. The lower part 220 of the pin has a length of 33 mm., A diameter 225 of the inner hole of the pin, conical which decreases from 19 mm. to 18 mm., and an outer diameter of the spike of 44 mm. The transition between

The upper part 230 of the pin and the lower part 220 of the pin can be made by an intermediate piece 255, which runs in a conical shape along a length of about 1 mm. The bottom 220 of the spike can be grooved.

2nd. Example (Figure 6): The upper part 310 of the spindle has a length of 55 mm., A diameter 315 of the inner hole of the spigot of 24 mm. and an outer diameter of the spike of 44 mm. The lower part 320 of the spike has a length of 33 mm., A diameter 325 of the inner hole of the spike of 18 mm. and an outer diameter of the spike of 44 mm. The transition between the upper part 310 of the shank and the lower part 320 of the shank is carried out by means of an intermediate piece 330 which runs in a conical shape along a length of about 3 mm. The shaft 301 of the inner pin hole of the bottom part 320 of the pin is twisted about 2 mm. with respect to axis 316 of the inner hole of the pin of part 310

15 top of the pin, which corresponds to the axis of the pin, which in this embodiment coincides with the axis of the hole. The position of the axes is illustrated in the cross-sectional drawing of Figure 6.

3rd. Example: In the measurements of the pin 200 of the first example (Figure 5), the inner hole 415 of the pin of the upper part 410 of the pin and the inner hole 425 of the pin of that of the lower part 420 of the pin is eccentrically offset with respect to the pin 400. This means that the shaft 20 416 of an inner hole 415 of the upper pin and an inner hole 425 of the lower pin, is displaced, for example, about 2 mm . with respect to the shaft 401 of the pin, as illustrated in the cross-sectional drawing of Figure 7. If this pin 400 is placed in the joint system according to the invention, the shaft 401 of the pin coincides with the hole shaft. When using the exemplary embodiment of the pin 400 as the first pin 60 and as the second pin 70, the first pin 60 and the second pin 70

25 are offset from each other about 15 ° when making the connection, that is to say, they are introduced in the first and second holes with an orientation of the eccentricities of the axis 416 in the first pin 60 and of the axis 416 in the second pin 70 which is not coincident.

In figure 9b and c three other ways of executing the plug are shown. In the embodiment of Figure 9c, a pin 110 has a flange 810, as shown in the detailed view of Figure 9c. Pin 110 has

30 an outer diameter of 18.8 mm. The depth (3.5 mm.) Of the flange 810 is greater than the eccentricity of the shaft of the inner hole of the pin of the corresponding pin 60, 70. Figure 9c shows two ways of executing the pin. Both embodiments of the plug 910 and 920 have longitudinal grooves 930 on the surface of the plug. In an embodiment of the pin 910, those longitudinal grooves 930 are deep. In another embodiment of the pin 910, those longitudinal grooves 930 are configured flat.

35 Figure 10 shows a system 1000 comprising the two constructive elements 1010 and 1020, with pre-assembled 1030 pins, 1040 bushings and 1050 pins. The 1030 pins, the 1040 caps and the 1050 pins can be mounted in advance on one of the elements 1010 and 1020 constructive - for example in the factory of constructive elements - and the constructive elements 1010, 1020 can therefore be quickly mounted on site.

40 Figure 11 illustrates another embodiment of the system 1000. A wall is formed of a number of constructive elements 1110, the pins, pins and bushings being defined as 1120 in this example, previously mounted on the constructive elements 1110.
