Description

 The invention relates to construction, in particular to devices for installation and repair of wooden flooring and floors.

A device for repairing wooden floors in the form of a fastener - studs, installed all the way into the ceiling. (Aut. St. 547513, M. cl. E 04 F 15/02, publ. Bull. 7, 1977.)
A device for repairing wooden floors containing a threaded rod is known. Passing through the flooring and the beam, the threaded stud abuts against the slab, forming a floor support, while the stud does not protrude beyond the floor surface. (Aut. St. 445736, M. class. F 04 F 15/00, publ. 1974)
A device for repairing wooden floors is known, comprising a threaded sleeve and a fabric cover located between the flooring and the surface of the base into which the hardening mixture is pumped. (Aut. St. 1000534, M.C. 5 E 04 F 15/02, publ. 1983)
The use of a hardening mixture and a removable hairpin does not allow subsequent adjustment of the floor position.

A device for repairing wooden floors, comprising a sleeve with a female thread and a threaded rod, the upper surface of which is installed above the floor surface. The sleeve is provided with tabs having a width greater than the width of the sleeve wall, and the thread is on the ends facing the sleeve. The hairpin is passed through the sleeve with the last paws fixing by turning them all the way to the bottom floor when the paws interact with the moving hairpin. (Aut. St. 1206415, M.C. 5 E 04 F 15/02, publ. 1981)
The sleeve and the threaded rod are used only for the time of injection of the quick-hardening mixture. The use of studs and bushings removed from their holes does not allow subsequent adjustment of the floor position.

Known closest to the proposed device for the repair of wooden floors, containing a housing in the form of a tubular element with an external thread and an internal cavity, inside of which a support pin (rod) is freely mounted with a gap with the possibility of axial movement. The cavity of the body is filled with an adhesive composition with the possibility of flowing it in the direction to the supporting part of the stud (rod) to increase the reliability of mounting of the support. (Aut. St. 1560705, M.C. 5 E 04 F 15/02, publ. 1990)
The use of the adhesive composition creates an inseparable connection and does not allow subsequent adjustment of the floor position. During repair, it is possible to create local stresses, which during subsequent operation, and often after a few days, cause the lifting of individual sections that require additional adjustment.

 The use of a support pin of one constant length requires a large length of an expensive case for the possibility of repairing floors with a variable depth space between the floor and the base. You have to deal with the trimming-trimming of the studs or have a large supply of studs of different lengths.

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

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

 This task is achieved by the fact that in the device for the repair of wooden floors, comprising a body with an external thread and an axial hole and a rod, the axial hole of the rod is blind, and the rod is installed all the way and fixed and fixed, while moving the rod all the way into the concrete base axial movement of the housing relative to the floor. The rod can be made prefabricated from several elements and is equipped with persistent and soundproof elements, and the housing is installed in a sleeve fixed to the floor.

The drawings show:
figure 1 - General view of the proposed device;
FIG. 2 - the same, with a rod made of several elements, and with a housing installed in the sleeve;
figure 3 is the same with the nipple connection of the sleeve with the floor.

 A device for repairing wooden floors comprises a housing 1 (Fig. 1) with an external thread and a rod 2. A blind hole 3 is made in the lower part of the housing 1, in which the upper end of the rod 2 is placed until it stops. The rod 2 is fixed in the hole 3 with a thread or a tight fit.

 The rod 2 is moved to the desired position all the way into the concrete base 4 by axial movement of the housing 1 relative to the floor 5 by rotation. Depending on the height H - level of the floor 5 relative to the concrete base 4, one rod 2 of the required length or a prefabricated rod 2 of several elements 6, 7 are used (Fig. 2).

 The rod 2 can be equipped with a thrust element 8 and a soundproofing element 9.

 The housing 1 can be equipped with a sleeve 10 mounted in the floor 5, connected to the housing 1 by a thread. The sleeve 10 (Fig.2,3) can be fixed in the floor 5, for example, using the nipple connection 11 (Fig.3).

 The device operates as follows. A threaded hole 12 is made in the floor and the distance H is measured from the floor level to the concrete base 4. The length of the shaft 2 is selected taking into account the length of the body 1 so that its upper part does not protrude above the floor level 5. The body 1, the shaft 2, and the resistant cement 8 are assembled. and a soundproofing element 9. The whole complex is introduced into the hole 12 of the floor 5 by rotating the housing 1 all the way into the concrete base 4. The opening of the floor 5 is plugged with a stopper 13.

 Making the housing hole deaf with the rod fixed in it until it stops and moving the rod to the desired position (all the way to the concrete base using axial movement of the body) simplifies the design, does not require additional devices associated with the use of glue, and allows additional adjustment.

 The implementation of the rod prefabricated from several elements reduces the time and labor required to create a rod of the required length.

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

 The use of a soundproofing element reduces noise phenomena.

 The use of a sleeve for mounting the housing increases the reliability of the connection to the floor by increasing the area of contact with the floor and increases the bearing capacity.
