Object of the invention is to provide a new type of connecting structure, which would allow connection logs, possessing strength, flexibility, ability to retain heat and provide convenience and ease of Assembly, and, if necessary, ease of disassembly, and not requiring the use of nails, bolts, rods or other connecting devices made of metal or other materials. Connecting structure for connecting walls built from stacked on each other logs containing the rack and connect the swallow's tail, made in the front and on the ends of logs, to connect together the rack and logs, characterized in that hour at least on one side of the dovetail connection is closing the ledge, made as an integral part in one piece with it and overlying the sides of the logs at a certain distance from their end. 9 C. p. F.-ly, 9 Il.

The present invention relates to a connecting structure, characterized in restrictive part pubbie connection collected by performing matching profiles or grooves on the opposite surfaces of the logs, i.e., on surfaces that are installed at each other, which allows be laid firmly crossed logs one on top of another. Robovie compound is obtained as a whole load allocation, and appearance.

There are a number of problems and disadvantages associated with corners. Lots of logs, protruding beyond the corner, significantly increase the consumption of timber. Intersecting logs gradually bent, compressed, swell and move in different ways, which leads to the formation of gaps between them, impairing the insulation of the angle. The next problem is that building a solid frame with a tight-fitting logs is difficult and painstaking work, and that robovie connection can connect together only two walls.

Another disadvantage srubowo design is manifested in the fact that the construction of wooden buildings generally must be performed sequentially on a single crown, and this means that the build log frame is slow and fraught with significant zatrudnieniu design, in which the angle formed by the bar, to which logs are attached with their ends by means of a dovetail connection.

However, this solution is impractical, as in the case of performing tight-fitting joints with neat appearance, the Assembly of such construction becomes almost impossible. On the other hand, if the connections are made more free, which allows the Assembly of the design, they are loose, stiff enough and look messy.

The aim of the present invention is to eliminate the above disadvantages. A particular object of the invention is to create a new type of connecting structure for making a log walls, which would allow to get the connection logs, possessing strength, flexibility, ability to retain heat, density, and provides convenience and ease of Assembly, and if necessary, ease of disassembly. Another objective of the invention is to provide a connecting structure for trunks that do not require the use of nails, bolts, rods, or any other individual connecting devices made of metal or other materials.

Connection dovetail used in the proposed design, are preferably run at the end of a log pile, and a rack grooves. The design also allows reverse the decision at which the groove perform at the end of the logs, and tongue - in rack. Furthermore, in the amount of us the alignment of the logs and the rack in grooves can be inserted Board with two grooves, the profile of which corresponds to a space formed by the grooves, so that a wedge-shaped Board connects logs and rack.

The rack preferably has at least two elements of the dovetail connection oriented or open in different directions and which can be located in relation to each other at right angles, the expanded angle or any other angle. You may also attach to a single rack of several log walls, going in different directions.

In one embodiment, the stand has a groove and removable fringing the bar with the closing ledge running the length of the rack. This strap allows you to fully open the groove with one hand so that the logs can be opened from the side and stacked on top of each other in the groove of the rack, and then surrounding the bar again set on the rack, thereby securing the logs in place. Fringing strap can be fastened with appropriate screws, and if necessary even with glue.

In yet another embodiment, a strut connecting the two corner wall at an angle of 90oto each other, sostoaowith constructed walls. Thus, the same profiles with the element connection dovetail can be used to create an exploded angle, i.e., to continue the wall in the same direction, by gluing these profiles together at their contact surfaces. In addition, in this embodiment, preferably between contact surfaces can be glued narrow wedge-shaped element. Thus, using the same basic shapes and suitable wedge-shaped element, one can construct the corners, the walls of which are at different angles, the components preferably 120 and 135o.

In another embodiment, a compound dovetail contains addictive element used to pull logs to the rack in a longitudinal direction. So addictive element may consist of wedges, a length which essentially corresponds to the height of the log and which, when the wall is injected into the gap between the tongue and groove, which leads to dense pressing the inclined contact surfaces of the tongues and grooves to each other. Even at the base of the tongue or groove of the groove, allowing the use of thicker and more the Yong as addictive Reiki with the tabs, and in this case, the stand has a wedge-shaped protrusions corresponding to the protrusions on the rail. During the construction of the log walls of the projections on the rail and the tabs on the rack as close as possible to each other. At the end of the Assembly on one end of the rail strike, so that the rake moves away from the rack through her ribs, pressing thereby the logs close to the joints dovetail rack.

The length of the projection on the rail is preferably equal to the height of logs, each log is pressed the corresponding protrusion. Another possible design solution, in which the rack has no tabs, but instead uses two oppositely oriented rail having oppositely located projections. In this case, after the installation logs in place of one of the rails being held in a stationary position, while the other strike, while logs are compacted in place. In this embodiment, the logs can be easily released from the compound by the attack on the rod, which when tightening the logs was motionless.

Addictive element used in the proposed connection designs may also consist of various eccentric elements which are located agema connection design has significant advantages compared with the known constructions. It is sewn and self-restrained, i.e., does not require the use of separate fasteners. If necessary, it can be easily tightened to obtain a sealed connection. Since the length of the joining surfaces of this design is the relatively large and is always greater than the length of the remaining surfaces lying between the logs, percolation of moisture through such a connection to be insignificant. In addition, due to the presence of the closing tabs, connection parts dovetail may have a size that provides enough free fit these parts for easy Assembly of the connection, both sides of logs delay between the closing edges. The design provides free, natural movement and stacking of logs relative to the vertical post. Another advantage of the design is that it is very simple and quick Assembly and disassembly without any damage to its components during these operations, due to the lack in the design of mounting accessories. Thus, using the proposed connection designs possible the construction of various parts built what's designs, subject to further complete the rebuilding or dismantling.

Below the invention is described in detail with reference to the accompanying drawings, in which:

Fig. 2 depicts a section view of the structure, essentially corresponding structures in Fig. 1;

Fig. 3 depicts one embodiment of the invention;

Fig. 4 depicts another embodiment of the invention;

Fig. 5 depicts a third embodiment of the invention;

Fig. 6 depicts a tightening device;

Fig. 8 depicts another addictive device, and

Fig. 9 depicts the construction of the rack.

The connecting structure shown in Fig. 1 and 2, includes a rack 2, connecting the two log walls 1 at right angles to each other. At the ends of the logs made vertical coupling grooves 3 in the dovetail, and the rack 2 has corresponding grooves 4. Therefore, the piles of logs 1 can be wound in the grooves with the upper end of the rack to attach the log 1 to the rack 2. Thanks to the wedge-shaped design of the connection swallows the us to the counter only this connection. An essential part of the design of the rack are closing the tabs 5, passing through the sides of the logs at a certain distance from their ends. These protrusions close the connection and any traces of machining, which may remain on the ends of logs. Thus, immediately after the installation logs obtained a complete connection.

In Fig. 2 depicts hour 2, assembled from several parts, glued to each other, allowing you to get more hard and straight rack. In addition, parts of the surface of hours that remain visible after Assembly, may be made from the wood of higher quality with fewer knots, while the inner part stand out more knotty and raw material.

In Fig. 2 also shows the door frame 16 attached to the rack 2. This box is attached a separate Board 17 having a groove in the dovetail shape of which corresponds to the groove 4 in the rack 2. It is obvious that the tongue can be made in the carton.

In addition, the hour, the profile of which is shown in Fig. 2 additionally has a through hole 20 that performs two functions. When connecting and sclause. A hole may be inserted into the corresponding rod or tube, through which part of the profile accurately align with the connection and pressing them to each other. In the ready rack in the hole can be located threaded rod that allows you to pull the lower beam, lying under the counter, and the upper beam lying on top of the rack, and to obtain a rigid structure. In this design the logs attached to the rack, can not feel any pressure; on the contrary, logs, depending on the specific circumstances, can move freely and be installed.

In Fig. 3 depicts an embodiment of the invention, in which two adjacent log walls, passing in one direction, is attached to the rack 2 via elements 6 connections dovetail. In this case, one of these walls forms the outer wall 7 and the other inner wall 8, and between them is the insulation gap that can be filled with an appropriate insulating material 9, such as, for example, cellulose wadding, which is administered by injection. In General such wall is designed to provide ventilation, and thus corresponds to a solid log wall.

In Fig. 4 sobre logs attached to the rack by means of a separate Board 11 with two grooves, profile which conforms to the shape of two opposite grooves. In this embodiment, the Board 11 is set at the location of the pieces, the length of which corresponds to the height, for example, one or three logs, because installation of the whole length of the Board 11 may be difficult, and these pieces put in place after installation of an appropriate number of logs.

In an embodiment of the invention shown in Fig. 5, the rack 2 contains a removable fringing the bar 10 attached thereto by bolts 18. This bracket forms part of the groove 4 hours and also has a closing protrusion overlying side of an end of the log. In this case, log 1 can be stacked on top of each other and placed in front of 2, with no need for winding logs into the groove with the end of the bar 2. After laying logs in place of the bar 10 establish into place and firmly fixed with a bolt, thus assuring to place logs in the rack.

With the application of the proposed connection dovetail usually get quite tight and rigid connection, strengthening the structure as a whole, and for this it is enough to make the logs into the grooves of the uprights and put these logs each other with the example by entering wedge 12 in the gap between the rack 2 and the end of each log 1, as shown in Fig. 6. The wedge presses the beam 1 and the rack 2 in opposite directions, causing the tight pressing of the inclined surface 14 of the sheet corresponding to the inclined surface 15 of the groove (Fig. 7).

The tongues and grooves can be made so that their sizes provide free boarding, so that between them can be inserted into the wedge 12 of appropriate size. As shown in Fig. 7, in the bottom of the grooves can also be made as a separate key groove 21 for tightening wedge. In addition, you can use this groove addictive element 13, which is shown in Fig. 8 and which is an addictive rail ledges. In this case, in the bottom of the key groove of the corresponding protrusions having the opposite orientation. It is also possible to use two addictive rails 13, which are located in the key groove with the opposite orientation, so that the protrusions are located opposite each other, while after installation logs these rails and tighten rasklinivanie.

You can also use groove 21 as a sealing channel, in other words, this groove set the corresponding sealing rail is pressed against the end of the log. In addition, the Fig. 9 shows the profile of one way of carrying out the invention, in which the rack consists of two identical profiles 18 with a dovetail connection. Each individual profile 18 can be made of one or several parts. If such profiles are connected to each other directly, their surface connections are angled 45oto the walls, which are attached to these profiles, so that the profiles form an angle of 90o. However, in the case shown in Fig. 9, between profiles with dovetail connection can be pasted wedge-shaped profile 19, designed to create the necessary angle between the walls, which are attached to the rack. Thus, applying the same profiles 18, you can get different angles between the walls, components, such as 45, 60, 120, 135, 150 and 180oby using only the wedge-shaped profile.
