The invention relates to the field of construction, and in particular to methods of repair work, and can be used to restore the shape and hardness of the coatings without disassembly (sexual, wall, ceiling)mounted on a rigid base, mainly floors from wood (plank, parquet, particle Board and so on).
During installation and operation of various types of coatings possible deviation of the profile from theoretical form, the appearance of elastic deformation under the influence of workloads (in particular, when moving on wooden floors is their elastic deformation, often leading to the creaking floors).
The design of a number of coatings is as follows (for example, panel type in the sheet piling, wood flooring and so on), which often requires disassembly of a significant part of the coverage for repair (or replacement) weakened or deformed link, i.e. leads to great work. However, to eliminate the defects mentioned coatings in some cases it is possible and without removing coverings.
There is a method of repair of wood floors, namely, that in the place of the deflection of the floor bore through the through hole and is inserted into the studs. Each hairpin pre-cut in two at its upper end. The length of the stud set the rate so that it is approximately 10 mm exceeded the distance from betonovoznoy to the lower surface of the floor. Then with a hammer and nastavi in the cut score metal wedge 6. Forked end of the stud 4 diverges, and both of his half deeply embedded in the wood, forming a support for the floor to avoid subsidence. The upper part of the hole closing plug (Patent RU NO. 2044853, MCI 04F 15/02, 1995).
The known method suitable for the deformation of a sexual candy, however, it is not possible to accurately restore the profile of the floor surface, it is also possible destruction of the tree in places of wedging stud that much reduces the reliability of the achieved results.
There is a method of repair of wooden floors by drilling platform and the lag pair of through holes and then installing one of them threaded metal studs all the way into the concrete base discharge under the lag through the free hole hardening mixture, extraction of the stud the pressure and hardening of the mixture through the vacant hole (USSR Author's certificate No. 547513, MCL 04f 15/00, 1975).
However, the known method does not provide an effective repair of floors, eliminating the bowing of the only lag, but not the floor boards between the joists, which is also not possible to accurately restore the profile of the floor, in addition, the elastic deformation of the boards under the weight of the steps is the main cause of the creaking floor. In addition, atodorov characterized by increased complexity, due to the need of the mixture hardening preparations and additional technological operations.
Closest to the proposed to the technical essence and the achieved result is a method of repair of wooden floors by drilling the flooring and joists through holes and then installing them all the way into the concrete base of the threaded metal studs (USSR Author's certificate No. 445736, MCL 04f 15/00, 1974).
The known method suitable for the deformation of floor boards, but it is not possible to accurately restore the profile of the floor for the following reasons:
- does not resolve the deformation of the floor in the form of protuberances ("humps"), but only "depression"because of the repair effort from the rigid base to the floor;
- while eliminating strain on the screw connection stud-material flooring there are additional efforts that increase friction and can lead to breach of the threaded connection (especially when in contact with non-solid coatings of the type of wood), until its destruction, especially when carrying out adjustment operations.
In addition, on the basis of the above, this method complicates the re-adjustment works, which over time may be necessary, i.e. does not allow is to provide reliable and long-lasting effect when exposed to operational loads.
The present invention is the provision of a repair coating on the hard ground without Dismounting while ensuring recovery of theoretical profile of the floor, increasing the accuracy and the reliability and lifetime of the repaired areas.
This invention also allows you to shape the surface of the original form within strength (elasticity) of the material of the coatings, repair coatings, which expands the scope of its application.
This object is achieved in that the method of repair coatings that are installed on the hard ground without Dismounting, mainly floors from wood-based materials, including determination of the deformation of the coating, the determination depending on the hardness of the coating repair points, drilled in places through holes, installing them all the way into the hard ground studs with the subsequent creation efforts from the rigid base to the floor to reduce deformations, which according to the invention, the repair efforts on the flooring put in a couple of the adjusting elements (for example, a pair of threaded with fine pitch thread) is of a durable and wear-resistant material, than the coating material (excluding damage to the coating material in threaded connection with a pin). And in front of the net assets of the repair efforts through the adjusting elements allows to apply them not only in the direction from the rigid base to the deck, but in the opposite (eliminating deformation of flooring not only in the form of depressions, but in the form of bumps). When this is fixed or pin (if efforts toward the rigid base or in the case of thin coatings)or an element associated with the floor (in case of application of force from the rigid base), then repair (alignment) of the coating, and the efforts put from the points of minimum strain to the point of greatest deformation (especially for large deformations coatings or hard coatings, requiring either large displacements, or more effort), evenly distributing the repair load.
The invention is schematically illustrated in the drawings: figure 1 is conventionally shown cross-sections of the coatings on the hard ground in the places of their deformation:

According to the provided illustration consider the example implementation of the invention.
On the surface of the cover 3 mounted on the rigid base 1, for example at lags 2, determine the deformation (δ+, δ, δmax) (1) or designated squeak (mostly outdoor (figa)), then depending on the magnitude of deformation and rigidity of the coating determine the number of repair points, having them mainly in a radial direction relative to δmaxand drilling in these points cover the through hole of the required diameter (given the strength of the coating and the ease of mounting of the adjusting elements 4-5 (2)).
Depending on the hardness of the coating and the direction of application of force (F1F3or F2F4-F7- figure 2) choose the types of the adjusting elements stored is (with a fixed column (figure 3, 5, 6) or rotating (figure 4)and assemble them in the prepared holes. In particular, for thick coatings set (see figure 4): the adjusting element (5 2) rotate the bar 6 and is rigidly fixed in the hole of the cover and coupled to the reception of a threaded sleeve 7 in the case of the application of force from the rigid base; or (see figure 3) adjusting element (pos.4 figure 2) with a fixed column 8, mounted on the rigid base 1 by using, for example, the plugs 9 and associated threaded connection with the rotating sleeve 10, lay on the floor with the outside - in the case of efforts towards the rigid base. With the possible application of anti-friction elements (11, figure 3-6) to reduce the adjustment effort and wear of contacting surfaces.
In the case of thin coatings (figure 5-6), the thickness of which does not establish the elements of the "body" of the coating, it is possible to install movable elements 10 with emphasis on surface coatings. In the case of the application of force from the rigid base sleeve 10 supply spring legs 12 for insertion into the holes of the deck.
So, after the installation of the adjusting elements in openings of a flooring move the movable elements to the "spread" between the fixed base and the deck (for example, rotating with slotted elements or elements turnkey ITP).
After the above preparatory operations produce alignment coatings (figa) by moving the movable element in the direction of decreasing deformation. For uniform distribution of load leveling flooring is produced from the minimum to the maximum deformation mainly in the radial direction. For hard coatings and coatings with large deformations possible gradual alignment: for example, initially make a preliminary "rough" alignment (figb, F7-F11), then the final "fine" alignment surface flooring. If necessary, the movable elements at the end of the work record. Holes in the floor close up, for example, the tubes of the coating material, furniture tubes.
Thus, the applicant proposed to use a fairly simple and universal method of repair and the formation of different coatings without dismantling in high reliability of the repair and the possibility of subsequent setups.
