Abstract

Use: in the manufacture of parquet end shields. The invention of the timber is cut at an acute angle, diagonally from corner to corner, into pieces and form into shields. 1 h. ffl, 8 silt

Description

The invention relates to the construction industry of the national economy and can be used in the manufacture of end flooring in buildings for various purposes,

Methods are known for the manufacture of end floor coverings, including those made of parquet boards assembled from the constituent elements of various wood species, which are glued together by plastic planes, while the glue line is perpendicular to the underlying base.

The known method uses the physicomechanical property of wood to match their requirements to the parquet flooring (increased hardness, abrasion and durability) compared with the arrangement of shield elements (strips) along the seam m1.

However, the known method advantageously uses the advantages of the face arrangement of the wood texture, weakens the strength of the parquet face shield by crushing. Prerequisites are created for the fallout of individual elements from the shields during operation, since in this case the wood fibers are directed along the line of action of the shear force.

The closest known technical solution is a wooden composite plate and a method of manufacturing a wooden composite block by cutting a bar into elements (drafts) at an acute angle to the base, laying them on the end surfaces and gluing their side faces between them.

The disadvantage of this technical solution is the increased thickness of the plate, the increase in labor intensity in the manufacture, and the reduction of the use of wood waste

The purpose of the invention is to increase the durability of the resin while ensuring savings in material consumption due to the use of wood waste.

The goal is achieved by cutting the blank billet diagonally from corner to corner at an acute angle on the checkers (elements), placing them on the end surfaces and gluing the edges. The blank can be glued in a known manner from individual slats, and the checkers (elements) can be laid on face surfaces with their rotation by 180 ° through time

In the method, all four outer edges of the parquet board and the constituent elements are inclined to the base plane.

and the two bordering adjacent edges are inclined at an acute angle, and the other two edges are inclined at an obtuse angle (equal to 180 ° minus the specified acute angle).

The proposed arrangement of the elements with an angle provides an increase in the area of gluing of individual elements between themselves (at an optimum angle by 30%), which leads to an increase in the strength of the parquet board as a whole on the floor, and giving the floors greater durability during operation.

The blank bar 1 is cut diagonally from corner to corner at an acute angle into pieces 2, of which 3 is a shield.
