The technical field to which the invention relates.

The present invention relates to a composite construction element in accordance with the restrictive part of paragraph 1 of the claims.

The level of technology

From patent document FRG No. 10163446 A1 is known a composite construction element of this type, consisting of several layers adjacent to each other elongated plates or boards. Board layers superimposed on one another, have different directions and are connected to each other by nails, clamps, brackets or screws. Due to the different directions of the boards when laying in layers superimposed on each other, achieve a high stability of the composite construction element. In particular quick and economical connection of boards of layers is achieved with simple nails hammered automatic nail hammering devices. However, because of the composite construction elements are subjected to repeated treatment, to provide a smooth outer surfaces or for the manufacture of parts of Windows or doors, steel nails are dangerous tools. Therefore, to prevent the risk of damage to tools in the further processing of the composite construction element was proposed aluminium or synthetic material for nails. It is possible, in the example, plane and the outer surface of the composite construction element in a simple manner without the risk of damage to tools, so that these outer surfaces can either be directly serve as exterior walls, or to serve as a base for painting, stickers, Wallpapers, and other processing. However, such processing of the composite construction element can cut the nail head, which impairs the integrity of the element.

Disclosure of inventions

The problem to which the present invention is directed, is to create a composite building element that provides improved communication between the individual layers.

In accordance with the invention the solution of this problem is achieved by the features set forth in paragraph 1 of the claims. Preferred examples of the implementation and further development solutions of the invention are protected in the dependent clauses.

In the composite construction element according to the invention the fastening pins, made of light metal or synthetic material, provided with annular projections spaced from each other in the longitudinal direction of the fixing pin. Using these annular projections creates a connection between the mounting pin and boards with the kinematic closure and due to this is improved about the relationship between the individual layers of the composite construction element. Annular projections provide improved fastening fastening pins in the Board and prevent the weakening of bonds between layers even in the case when the locking pin has no head or the head is cut off, for example, when the planing Board. So manufactured composite construction elements have a high stability and can easily withstand the shaking during transportation and installation without separation or relative displacement of the layers.

In the preferred exemplary embodiment the fastening pins contain the rod, tapering cone to the tip. Because of this, when driving of the fixing pin Board material effectively shifted to the side, not only the front part of the rod, but in its rear part, so that the rear mounting pin due to deformation of the material is sufficient retention clamping force. Due to this decision, the outer layers of boards also held with high strength. Due to the presence of annular projections of the mounting pins with cylindrical shank also have high holding power for safe connection of the individual layers of the boards of the composite construction element.

According to a preferred exemplary embodiment of the annular protrusions are in longitudinal cross-section symmetrical shape. While retaining pin creates the same derives the Yu strength in both longitudinal directions. The protrusions may be made triangular, rectangular or trapezoidal.

Preferably the protrusions spaced from each other in the longitudinal direction of the fixing pin, have the same dimensions. However, they may also have different widths or heights or different forms.

In the exemplary embodiment, with benefits in terms of constructability and economy of manufacture, the two boards lying one on the other layers are connected in a crossing by means of at least two diagonally spaced mounting pins. Due to such a diagonal connection is also achieved extremely high rigidity of the element.

Especially high density composite construction element can be achieved due to the fact that the boards of the individual layers are connected to each other at their longitudinal sides by connecting the tongue and groove or through sportowego profiling.

Between the individual layers of the boards can be laid intermediate layers of film, paper or other suitable material. As shown, particularly suitable materials are sealing film, allowing the diffusion of wind-proof paper or similar materials.

In the preferred embodiment, the fastening pins can be made in the form of humic substances is SDA with head or without them. However, they can be made in the form of clips, brackets, or other elements.

The implementation of the invention

Figure 1 shows the composite construction element 1 in the form of a wall element, which consists of several layers of 2 boards 3, located in the layer next to each other. On the plot shown in Fig. in a larger view, you can see that Board 3 two layers 2, superimposed one upon the other, are placed with a relative offset of 90°, so that a design of high density and strength with layer shifting elements. Some boards may have the same or different width, as shown in figure 1.

As can be seen in figure 2, a separate Board 3 single layer 2 are connected to each other using sportowego connection 4, which is here made in the form of connections in the quarter, which provides a particularly tight connection boards 3 in the pile. In addition, in the example shown performing on the inner side boards 3 are provided with longitudinal parallel grooves 5. Due to this, between the individual layers can be created with an extra layer of air. In the shown example, the execution of Board 3 layers 2 have the same thickness, which simplifies the construction of the wall. However, the composite construction element 1 may consist of layers of different thickness. Boards of different layers do not necessarily have to be trim or sliced, as shown in figure 2. Especially in the inner layers of the composite construction element can be used so-called side plank, which in the manufacture of lumber go to waste wood. Due to this, may be reduced manufacturing cost. In addition, through the use of so is x boards is an easy way to ensure the creation of air pockets between the layers and to improve the sound insulation properties of the composite construction element.

In the zoomed plot in figure 2 shows that boards 3 a single layer 2 is connected with the boards of the following layer 2 by means of fastening pins 6, which will be described in detail hereinafter. As shown in figure 3, the fastening pins 3 are arranged diagonally so that the boards 3, superimposed on each shift, connected to each other in a crossing or overlapping of the two diagonally spaced mounting pins 6. Due to such a diagonal connection is achieved extremely high rigidity of the element. In the exemplary embodiment of figure 2 mounting pins 6 hit not only in Board 3 adjacent layer 2, but partly also in the boards of the underlying layer.

Manufacture of composite construction element is preferably as follows. First on the table or workbench stack the first layer of several plates 3, arranged in parallel next to each other. Then the number of boards shrink with lateral clamping devices to fit their longitudinal sides. Next, the first layer is placed second layer of boards so that the top boards are transverse to the boards of the bottom layer. Preferably the boards of the upper layer stack on the Board of the lower layer with an offset at a 90°angle. Using the other side of the mounting bracket top Board also unite to plotno who fit their longitudinal sides. Additionally, the top Board 3 is pressed to the underlying boards with vertical clamping device and then fasten them with the bottom boards 3 by means of mounting pins 6. The fastening pins 6 injected with nail hammering device with automatic control. To do this, when laying measure the width and position of the boards using appropriate measuring devices. According to the data obtained can determine the exact position of the mounting pins 6. When this positioning automatic nail hammering device can be controlled so that, for example, in the area of a crossing or overlapping of the two lying one above the other boards 3 anchoring is performed by at least two mounting pins 6, preferably diagonally opposite this area. Further accordingly can be laid following layers of boards with mounting the following mounting pins 6 to achieve the desired total thickness. After that, the Board 3 of the outer layers 2 can be planed in order to serve either the outer wall or base to paint, plasterboard, Wallpaper and similar coverings.

Figure 4-8 shows the different mounting pins for mounting of separate boards. The fastening pins are made of light metal, preferably aluminum. Aluminum on lady high strength, but soft enough to be processed by tools for working wood. The fastening pins may be made of wire, wound into a roll or the Bay. With the help of a special device, the wire can unwind from a roll or Bay, to stand up and be cut into segments of desired length. The fastening pins manufactured in this manner can further without additional machining to meet the store nail hammering device and then be entered into boards, for example, by using air under pressure.

The locking pin 6, is shown in Fig.4-8, made in the form of a rod 8 with annular projections 7, point 9 on the front end and the enlarged head 10 at the rear end. Round in cross section of the rod 8 is narrowed to the tip 9 of the cone, that is, its outer diameter continuously decreases to the edge 9. Annular projections 7 on the outer surface of the rod 8 are separated from each other in the longitudinal direction of the fixing pin and have the same shape and size.

The locking pin 11, is shown in figure 5, differs from the previous example only in that it has no head. Corresponding elements of the fixing pin are denoted by the same positions. Using such a fixing pin 11 without special heads can also be created sufficient retention efforts.

In the example you is filling up on p.4-8 circular protrusions 7 are made in the form of saw teeth with sloping front side 12 and a steep rear side 13. Due to this, may be reduced the force required for driving the mounting pins 6.

The protrusions 7 can also have in cross section the shape of a triangle, rectangle or trapezoid, expanding or Contracting out, as shown in figa-9d.
