The invention relates to the construction, in particular to devices for mounting and repairing wooden decks and floors.

A device for repair of wooden floors in the form of a fastener stud, installed all the way into the ceiling. (Ed.St. 547513, M CL E 04 F 15/02, publ. bull. 7, 1977.) A device for repair of wooden floors, containing a threaded stud. Passing through the deck and beam, a threaded stud rests VG.) A device for repair of wooden floors, containing the threaded sleeve and fabric cover placed between the flooring and the base surface, in which I store the hardening mixture. (Ed.St. 1000534, M CL 5 E 04 F 15/02, publ. 1983.) The use of hardening the mixture and extracted studs does not allow subsequent adjustment of the position of the floor.

A device for repair of wooden floors containing sleeve with internal thread and the threaded rod, the upper surface of which is installed above the floor surface. The sleeve is provided with legs having a width larger than the width of the wall sleeve, and thread on facing the sleeve ends. The stud is passed through the sleeve with fixing last legs by turning them all the way to the floor below when interacting feet with a moving pin. (Ed.St. 1206415, M CL 5 E 04 F 15/02, publ. 1981.) The sleeve and the threaded stud is used only at the time of discharge rapid hardening mixture. Use extracted from their holes studs and sleeve does not allow subsequent adjustment of the position of the floor.

Known closest to the proposed device for repair of wooden floors, comprising a housing in the form of a tubular element with an external thread and the internal bands of the Yan). The cavity of the housing is filled with an adhesive composition with her flowing toward the supporting part of the stud (stud) to improve the reliability of fastening of a support. (Ed.St. 1560705, M CL 5 E 04 F 15/02, publ. 1990) Using the adhesive composition creates a permanent connection and does not allow subsequent adjustment of the position of the floor. During the repair, you may create local stresses, which in a subsequent operation, and often after a few days, cause the raising of separate areas requiring additional adjustment.

The use of anchor studs one constant length requires long lengths of expensive housing for repair floors with variable depth of the space between the floor and the base. It is necessary to adjust the cutting of studs or to have a large supply of pins of different lengths.

All this increases labor costs, reduces productivity and does not ensure the quality of repair due to the impossibility of subsequent adjustment.

The task of the invention is to reduce labor costs, increase productivity and quality of repair.

This task is achieved in that the device for repair of wooden floors containing co is set to the stop and it and fixed, during this movement of the rod to rest on a concrete Foundation produce axial movement of the body relative to the floor. The rod can be made teams of several elements and is equipped with a resistant and sound insulating elements and the casing is placed in the sleeve, fixed to the floor.

In the drawings shown: Fig.1 - General view of the proposed device; Fig. 2 - the same, with a core made of several elements, and the housing mounted in the sleeve; Fig.3 - the same, with threaded connection of the sleeve with the floor.

The device for repair of wooden floors includes a housing 1 (Fig.1) with an external thread and the rod 2. In the lower part of the housing 1 is made blind hole 3, which houses the upper end of the rod 2 until it stops. The rod 2 is fixed in the hole 3 with a thread or landing with tension.

Movement of the rod 2 in the desired position until it stops in the concrete base 4 produces axial movement of the body 1 relative to the floor 5 by its rotation. Depending on the height H - floor level 5 on the concrete base 4 use one terminal 2 of the required length or bulk terminal 2 of several elements 6, 7 (Fig.2).

The terminal 2 may be provided with a thrust element 8 and sound . Tolka 10 (Fig.2,3) can be fixed to the floor 5, for example, using a threaded connection 11 (Fig.3).

The device operates as follows. Perform in the floor of the screw hole 12 and measure the distance H from floor level to the concrete base 4. Choose the length of the rod 2 with regard to the length of the housing 1 so that its upper part is not played above floor level 5. Assemble the housing 1, terminal 2, resistant cement 8 and sound insulating element 9. The entire complex is injected into the hole 12 of the floor 5 by rotation of the housing 1 until it stops in the concrete base 4. The hole in the floor 5 of the muffle tube 13.

Execution openings deaf fixed install rod until it stops and move the rod in the desired position (fully down to the concrete base with axial movement of the body) simplifies the design, does not require additional devices associated with the use of glue, and allows in operation for more adjustment.

The implementation of the core teams of several elements reduces the time and effort of the rod to the appropriate length.

The supply rod thrust element increases the contact area of contact with the concrete base.

and housing increases the reliability of connection with the floor by increasing the area of contact with the floor and increases the carrying capacity.
