Description

Description of the invention

The claimed group of inventions relates to the woodworking industry, namely to elements for 2 floor coverings. It can be used in the technological cycle of their production and when laying floor coverings in residential premises, offices, theaters and other objects.

At this time, the floor covering is subject to a set of requirements related to its quality, in particular to its strength characteristics, and to the possibility of giving it decorativeness. A wide range of floor covering elements is needed to meet the numerous demands of the consumer. 70 The closest thing to the claimed object is the floor covering element described in the OA patent

Mo29364. It is a plate consisting of a set of lamellas, and the plate is a cut of bars glued along the side surfaces. The cut is a plane perpendicular to the direction of the wood fibers.

A known floor covering element intended for gluing on a shield, while the resulting structure 72 makes it possible to reduce labor costs for installation work. But when a known floor element is laid, it bends under its own weight and its destruction is possible, since the arrangement of fibers perpendicular to the plane of the floor does not contribute to the acceptance of tensile loads.

The specified location of the fibers can cause the coating to chip due to shock loads.

In addition, the known floor covering element is characterized by insufficient resistance to moisture, which leads to deformation and distortion of its shape.

The task of the present invention is to improve the element of the floor covering by changing the tectonic loads on the wood fibers, as a result of which tensile strength, resistance to impact loads is achieved and the probability of deformation of the covering and distortion of its shape is eliminated.

The problem is solved by the fact that the floor covering element, which is a plate, which with 22 consists of a set of lamellas made of wood, according to the invention, the lamellas are characterized by the arrangement of wood fibers in a horizontal plane, and the plate is a section of bars glued together side and end surfaces.

The known method of manufacturing an element for covering the floor (patent OA Mo29364) includes the following technological operations: -- 30 - bars made of various types of wood, which have been previously dried, are placed on the shield in such a way that the wood fibers are located perpendicular to the shield; - the bars are glued together with their side surfaces, the block is cut into plates in the direction transverse to the M arrangement of the fibers; If necessary, the F plate is glued to the shield or strengthened in another way.

But the prototype method has inherent disadvantages, which are due, first of all, to the location of M wood fibers in the lamellas, which are joined by gluing. The known element for covering the floor is not sufficiently resistant to compressive-tensile loads, which increases the probability of its breakage during installation work. And, in addition, it does not withstand impact loads well, which leads to chipping. Excessive water absorption, which is inherent in the known method of covering the floor, leads to its deformation. With 40 The existing restrictions on the resistance of the known floor covering to certain loads are compensated by reducing the dimensions of the plate. z" Preliminary drying of the bars is a very long process, since the subsequent gluing of the bars and sawing of the resulting block into plates involves the use of bars of significant thickness.

The task of the second invention is to develop a method of manufacturing a floor covering element by changing 45 sets of technological operations, as a result of which higher consumer properties of the specified e element are achieved, and the labor intensity of its manufacture is reduced. (Te) The task is solved by the fact that in the method of manufacturing an element for covering the floor, which includes gluing wooden bars with their side surfaces, cutting the resulting block of bars into plates, shk according to the invention, gluing the bars is carried out both with their side surfaces and with their ends , and cutting ka 20 into plates is performed parallel to the planes of fiber arrangement.

The claimed method allows you to glue bars of different shapes and sizes. In addition, bars can be made of different types of wood.

Features of the proposed method include the execution of a decorative pattern or ornament on the outer surface of the plates.

In the proposed element, gluing of bars with their side and end surfaces and the following

ГФ) cutting the obtained blocks into plates parallel to the planes of the fiber arrangement in their entirety determine the high consumer properties of the floor covering. o Longitudinal arrangement of fibers in the lamella helps to increase the resistance to tensile-compressive loads and shock loads, as a result of which the resulting floor covering element is subject to significantly less breakage during installation work and chipping compared, for example, to the prototype.

The indisputable advantage of the protruding element is its high resistance to moisture, which is explained by the location of the fibers in the lamellae.

The production technology of the proposed element involves the use of bars of a smaller thickness, but at the same time a larger plane, which allows you to speed up the process of their preliminary drying. because the elements of the floor covering, made in accordance with the prototype method, are placed on the shield,

fix them on the shield, for example, by gluing. This technology is the least time-consuming, as it allows to perform many preparatory operations in factory conditions, including polishing the surface, adding decorative properties to it.

The proposed method expands the possibilities of automating the process of serial production of parquet blocks.

The essence of the invention is explained by the drawings, where Fig. 1 shows a block of glued bars according to the invention, while the direction of the fibers coincides with the longitudinal axis of the element itself, and Fig. 2 shows a plate that is an element of the floor covering according to the invention and which is obtained from block shown in Fig. 1 / about the means according to the invention.

Figure 3 shows a block of glued bars, in which the axes of the bars form an angle with the longitudinal axis of the block itself;

Figure 4 shows a plate obtained from the block in Figure 4 according to the invention.

Figure 5 shows a block of glued bars, in which the axes of the bars form any angles with the axis of the block itself;

Fig. b6 shows a plate obtained from the block in Fig. 5 according to the invention.

Fig. 7 shows a block of glued bars, which have a figured shape with a decorative purpose,

Figure 8 shows a plate obtained from the block in Figure 7 according to the invention.

In addition, the invention is explained by an example of a specific implementation of the method.

Example

Parquet blanks (bars) that are not suitable for the production of high-quality parquet due to their small linear dimensions (length 100-300 mm) are dried and processed accordingly, and their side and end surfaces are glued into a monolithic piece with dimensions of approximately 3000x1000x1000mm. Gluing is carried out by any known method.

Then the board obtained from the glued bars is sawn in the direction of the longitudinal axis into blocks 1 with a size of approximately 200x3000x10 mm.

After that, each block 1 is sprayed onto plates 2 with a thickness of 3-1 mm and the dimensions in plan the same as those of the corresponding block: approximately 200x300 mm.

The resulting plates are a set of lamellas 3, significantly exceeding the lamellas in size. Then i) plates are glued, like lamellas, on a wooden or concrete base.

Thus, the proposed object has a number of advantages, consisting of high consumer properties, technological simplification of installation works and reduction of labor costs associated with them, and increase of economic indicators. s « (o) « - . and? sh» se) sh» ime) - ime) 60 b5 shk ih a aeh.
