EA008486B1 - Laminated element for fixing panel parquet - Google Patents

Abstract

The invention relates to parquet fabrication and, in particular, to a method of fixing parquet boards or panel parquets therebetween.A laminated element of panel parquet fixing is placed in their longitudinal side edges and has a cross-shaped configuration (1), each radial plate of which is interposed in response longitudinal interstices (3) of adjacent edges of panel parquet (2).The laminated element is made of a sheet material and symmetric in shape, wherein the length of each radial plate constitutes at least 0.15 of the length of the panel adjacent edge.Depending upon the use of panel parquet the laminated element can be made of different materials: ferrous metal, e.g. steel, a non-ferrous metal, e.g. aluminum alloy, a thermoplastic, a thermoset plastic, composite materials, e.g. glass or coal-plastic.A laminated element being shaped as a cross and fixing parcel parquet provides quality flooring, simplifies laying of panel parquet and better parquet levelling.

Description

Technical field

The invention relates to parquet production, in particular, to the construction of interconnecting parquet boards or parquet boards.

State of the art

GOST 862.4-87 “Parquet boards” is known, according to which grooves must be made in the edges of the parquet boards to connect the parquet boards to each other with the help of dowels (Fig. 4, p. 1, 3).

Known parquet boards (Fig. 2), consisting of a wooden base, the upper front cover of parquet strips of the same width with straight milled edges and glued to the base in the form of square elements arranged in a checkerboard pattern. Grooves are made in the edges on all sides of the parquet boards to connect the boards between each other by means of inserting inset keys (advertising brochure of the White Forest Trade and Industry Company, Internet site. \ Ν \ ν \ ν.ρί iggaShgsh.gi).

The disadvantage of analogues is that the longitudinal key does not allow the parquet boards to move in only one direction perpendicular to the key, and in the direction of the length of the groove and the key there are no restrictions on the movement of the parquet boards. Installation of panels in this direction is carried out only visually or in a line by the carpenter-floorer. As a result of this, when laying the shields, they are installed with an inevitable displacement from one another. When laying large areas of parquet, the total value of the onset displacement can reach significant values that will be noticeable to the eye.

SUMMARY OF THE INVENTION

The aim of the invention is to ensure high-quality installation of panel parquet, eliminating the displacement of parquet boards in mutually perpendicular directions.

This goal is achieved due to the fact that the plate element for connecting parquet boards, placed in their longitudinal end grooves located at least at the corners of the panels, according to the invention is made in the form of a cross, each of the beam plates of which is designed to be placed in reciprocal longitudinal grooves of the mating ends of the connected shields.

The cross is made of sheet material and has a symmetrical design, while the length of each of the radial plates of the cross is at least 0.15 of the length of the mating end of the shield.

Depending on the intended use of parquet boards, the cross is made of various materials: ferrous metal, for example steel, non-ferrous metal, for example aluminum alloys, thermoplastic plastic, thermoset plastic, composite materials, for example glass or carbon fiber.

Disclosure of invention

The plate element for connecting the parquet boards 2, placed in the longitudinal end grooves 3, is made in the form of a cross 1 of sheet material, and the thickness of the cross 1 corresponds to the size of the groove 3 at the end of the shield 2, with which the cross 1 interacts.

In most cases, the cross 1 is performed in a symmetrical design, but it can also have an asymmetric configuration (not shown), while the length of each of the radial plates of the cross 1 in any case is at least 0.15 of the length of the mating end of the shield 2.

Depending on the intended use of the parquet boards, the cross is made of various materials: ferrous metal, for example steel, non-ferrous metal, for example aluminum alloys, thermoplastic plastic, thermoset plastic, composite materials, for example glass or carbon fiber.

Information confirming the possibility of carrying out the invention

Installation of parquet boards using a plate element for their connection, made in the form of a cross, is carried out in the following order.

Depending on the room, parquet laying is done from the center or from the wall. The first shield 2 is laid and a cross-shaped lamellar element 1 is installed in its end grooves 3 so that both of its mutually perpendicular beam plates reach the stop in the grooves 3. Then the second parquet board 2 is laid all the way into the first, while ensuring the entry of two other radial plates of the cross 1 in the grooves 3 of the installed parquet board 2, and align the shields 2 from the installed cross 1 in one obverse line.

Further installation of parquet boards is greatly simplified, since it is performed without the operation to align the front line of the boards, because each panel is diagonally sent to the stop on both mutually perpendicular sides of the cross. Next to the next installed parquet shield mortgages

- 1 008486 a lamellar element in the form of a cross is installed, the next parquet board is installed and the previous operations are repeated.

The achieved technical result consists in the fact that the design of the lamellar element in the form of a cross does not allow parquet boards to move in two mutually perpendicular directions and ensures high-quality floor laying. In addition, the installation of parquet boards is simplified, since there is no need to align the front line of parquet boards because it is obtained “automatically”.

A plate element for joining parquet boards placed in their longitudinal end grooves was introduced on a number of parquet floors laid for sports and dance events, and showed the reliability of the connection of boards, increasing the rigidity of parquet floors and reducing the likelihood of crevices at the junction of the panels.
