The invention relates to wood processing industry and agriculture, and may find application in the construction of agricultural storage facilities, shelters and residential premises.

Famous wooden structure, made of edged boards or logs or panels of timber, the latter is connected to the panel by means of a tension anchor bolts perpendicular to the joined elements, while the tension anchors are outside the joined panels [1].

The main disadvantages of this design are insufficient strength and rigidity, and tarcrete and roof.

There is also known a method of manufacturing panels of wooden beams, according to which is used to bond the bonded bars protracted bolts are in the holes formed in the bars [2].

The main disadvantage of these structures is the presence of a large number of internal openings in the bars, which entails a large number of internal microdefects in the joints of wood and metal, and therefore, the need for additional sealing elements and the complexity of the construction as a whole.

Closest to the invention to the technical essence and the achieved result is wooden brusovaya panel for roofs and floors, which consists of beam elements of wood, connected by means of anchor tie-rods passing through the holes located on one straight line perpendicular to the longitudinal direction of the beam elements under tension [3].

The main disadvantage of this design is the lack of free deformation and shrinkage, which entails the need for periodic tightening of anchor ties. This makes it virtually impossible to use these structures as panels for roofs and floors, providing uniform shrinkage designs and increased stiffness at bond.

The problem is solved wood timber panel for roofs and ceilings, consisting of rails fastened by tie-rods passed through aligned holes in the bars, in which the panel edges are placed parallel bars with a cross section greater than the cross-section other bars 1.5 - 2.5 times, while they are placed with one side flush with the bars the entire panel.

This ties in a wooden timber panels made in the form of a rod having at one end a heel attached to the beam, and the other thread with nut.

In addition, screed panels can be made in the form of a threaded rod and nut on both ends.

The essence of the invention lies in the fact that in the proposed wooden timber panels on its sides, i.e. on the one and on the other side of the panel fit profiled bars are 1.5 to 2.5 times larger cross section than the remaining bars of the panel. Thus these boards of the one side to fit flush with the beams of the entire panel and the other party to act with respect to all of the bars, resulting in the panel are formed ribs.

This design gives increased rigidity of the Proposed panel can be laid ribs up and down. If the panel is placed ribs up, on the one hand it is a smooth wooden surface, does not require additional finishing, and on the other side between the ribs possible soundproofing and insulation.

If the panel is placed ribs down, a decorative beamed ceiling and the possibility of the original design, then the other side of the panel can serve as a smooth floors that do not require additional processing.

In Fig. 1 shows a General view of wooden timber panels for roofs and ceilings; Fig. 2 - mount two of the panels (option 1); Fig. 3 shows the fastening two panels together (option 2); Fig. 4 - node a in Fig. 3; Fig. 5 - mount two of the panels (option 3).

Wooden brusovaya panel (Fig. 1 and 2) is assembled as follows.

Example 1. Roof panel or overlay 1 are made of profiled timber 2 size 140 mm Connection bars 2 between them using tabs and slots, and along one edge of the beam is performed ledge and along the other edge of the groove. In bars 2 is a through hole with a diameter of 30 mm, which are the beam 2. The holes inserted tightening the rods 3 with a thickness of 30 mm, one side of which is welded anchor "heel", and on the other made the thread. By tightening the nuts on the threaded panel pull together as a result of neproporcionala reference "heel", in which there is a small hole, and through him it is fastened with a nail to the beam 2. The edges of the panel place the profiled bars 4 with a size of 280 mm, which on one side are placed flush with the beams of the entire panel, and the other are relatively bars the entire panel. To bond the panels 1 with each other in bars 4 perform through holes and insert the studs 5 and fix them with nuts 6 with two ends. In this case, the metal rods 3 are threaded at both ends and secured by nuts on both sides.

Example 2. Wooden square panel 1 manufactured in example 1, can be bonded together under option 2 (Fig. 3) as follows.

In the hole for a rod inserted a metal tube 3, one side of which is welded rear with holes in the middle with a diameter slightly exceeding the outer diameter of the pipe, and on the other hand do the carving. To connect panels optional use with the coupler 3. The rod 8 is made so that on the one hand they have a welded nut, and on the other thread. When connecting parala welded to the rod 5 thread is beyond extreme boards of the panel and the nut 6 is screwed on the thread. The final fastening of the panel through the washer with the nut 6 on the last thread of the rod 3.

Example 3. Wooden panel 1 manufactured according to example 1 can also be fixed between a version 3, is shown in Fig. 4.

The holes for fastening panels insert the rods 3, the first panel are used rods with 3 "heel" and carvings, and in the second panel is carved on both sides. The threads on the ends of the rods 3 screw sleeve 9 is threaded at both ends.

The use of the proposed wooden timber panels for roofs and floors allows you to provide the following benefits:

increased strength and rigidity of the panel;

uniform shrinkage design;

the full Assembly of the panel in the shop;

the simplicity and reliability of fastening of the panels during installation of the structure, which greatly speeds up commissioning.

1. Wooden brusovaya panel for roofs and floors, the situation is that the edges of the panels parallel bars with a cross section, greater than the cross-section other bars 1.5 to 2.5 times, while they are placed with one side flush with the bars the entire panel.

2. The panel p. 1, wherein the coupler is made in the form of a rod having at one end a heel attached to the beam, and another thread with a nut.

3. The panel p. 1, wherein the coupler is made in the form of a threaded rod and nuts on both ends.
