(54) PARQUET SHIELD

FIELD OF THE INVENTION The invention relates to woodworking industry and civil engineering, namely to the production and use of parquet flooring for residential and public buildings. The well-known wooden floor panel, including the slats, has longitudinal grooves and ridges for connecting the slats to each other, while the adjacent slats are interconnected by adhesive tapes arranged in two diagonal m of shield i. The closest technical solution to the invention is parquet shit, consisting of slats with slots, having longitudinal grooves and ridges for connecting the slats between themselves and flexible connecting elements, such as twine, pressed into the slits located on the non-face side of the shield 2. The disadvantages of these constructions are the impossibility of re-use of shields after wear of the front surface (by turning them over), as well as their low strength when laying shields on lags due to the presence of slots made The cross of the rails is from the non-face side. In addition, this parquet tape and the SHIELDS cannot be lacquered from it at the factory, since the lack of a tight connection of the rails into the groove and the comb makes it possible to bend the shield and damage the varnish film at the junction of the slats. The aim of the invention is to increase the life of the shield, reducing labor costs, material consumption. This is achieved by the fact that in the parquet board, which includes slotted rails, having longitudinal grooves and ridges for connecting the rails to each other and flexible connecting elements pressed into the slot, the groove is made in one of the ends of each rail and This slot is made in the grooves and ridges x. FIG. 1 shows a mosaic parquet shield, plan; in fig. 2 is a section A-A of FIG. one; in fig. 3 is a section BB of FIG. one; in fig. 4 is an exemplary layout of shields for flooring. The shield consists of a group of rails 1, having a groove and a tongue on the longitudinal edges, and connecting elements 2 in the form of a twine, a corrugated wire or a synthetic thread, pressed into the slot, located

in the central part of the ridge 3 and the groove 4, made on the ends of the rails.

In this way, the possibility of shield deflections in one direction or another is eliminated, and the strength of the shield due to the exclusion of transverse slots increases dramatically, and it can be laid on both a solid base and lags.

Shields can be supplied to the consumer with full factory readiness.

All technological operations for the manufacture of parquet mosaic tiles can be performed on highly mechanized lines assembled from domestic equipment. The mounting of fasteners can be done using a device widely used in the country's enterprises with a slight modernization.

The cost of the floors of the mosaic parquet tiles will be reduced by 30-40% compared to the known mosaic parquet tiles, and the service life of the boards

mr

will increase significantly due to their repeated use.
