CS198301B1 - Parquet block - Google Patents

Description

Wooden blocks have been known for decades. It is made of coniferous and deciduous wood like cubes - blocks of dimensions up to 10x15 cm and a height of 6 to 10 cm. It is impregnated with oil against atmospheric and wood decay effects. The blocks are laid individually in the sand bed with sealed joints or asphalt bedding. It was originally used as a paving of streets of entrances and passages, later mainly in the metal industry, where it met the highest demands. It allows versatile use, especially where floors are flexible, durable, durable and unpretentious. It gives the floor a warm, non-slip, dust-free floor with thermal and acoustic insulation properties. It is resistant to wear, impact, binds dust well, has an unlimited lifetime and just sweepes for cleaning.

Furthermore, it is low in weight, advantageous for the static load of multi-storey building structures, low electrical conductivity and thus the reduction of accidents. The use of block paving is also possible in residential and especially public and civic buildings. However, this requires perfect impregnation and abrasion and coatings to excel in the natural beauty of solid wood along with good mechanical and physical properties.

The disadvantage of the existing block paving system is the high consumption of wood and high labor intensity in the construction. Efforts to prefabricate and maximize the use of wood have led to various variants of production and assembly. In particular, it is French Patent No. 1,321,924 which has four variants of joining blocks and interleaving elastic inserts between the blocks of joined blocks. However, the blocks are again of the same height as the previous ones and without surface treatment, connected by gluing or staples to each other, and only the inserts interleave elastic inserts.

There is also a block floor, which is made of small blocks glued to a txtile mat. It is also known to solve the same problem, but without flexible inserts, with watering or interleaving up to the construction site.

Only joining traditional blocks into panes as palletizing did not lead to success and moreover, block floors were greatly reduced for high wood consumption. Now only industrial floors are used in industrial halls. Also, exhibition areas, distribution rooms, shops, schools, etc. have concrete or less valuable floors, often at the expense of workers' health and damage to machines.

These drawbacks and drawbacks are overcome by the present invention, which consists in that blocks of 10-15 mm thickness of the same or different types of wood are joined by gluing a flexible liner to form a block parquet board or frieze. For floors with visual requirements, this allows various combinations of wood colors, annual rings and block shapes, the surface is abraded and impregnated with oil, paraffin, etc. with a wax or varnish finish. No surface treatment of abrasion and coating, only Impregnated, for purposes where there are no visual requirements.

An exemplary embodiment of the parquet is shown in the drawing, in which Fig. 1 shows a block of a square format, Fig. 2 shows a log cut to billet billets, Fig. 3 shows the billet block punch from a billet; Fig. Fig. 5 shows a block of wood blocks in a view and Fig. 6 is a view of a block frieze.

When joining the blocks 1, an adhesive, preferably rubber, is applied to the two opposite side faces of the blocks and allowed to dry. The liner 2, such as a strip of cork pulp, rubber, PVC, etc., is coated with the same adhesive on both sides and, after a slight drying, is adhered to the assembled row of blocks 1. The liner 2 must always be smaller than The glue formed grooves 3 on the reverse side for bonding sealant or glue, by means of which it is glued to the substrate on site. Other rows of blocks 1 in number depending on the size of the board or frieze are glued in the same way. Then, by cutting the insert 2 behind the individual blocks 1, rows of blocks 1 connected by a flexible insert 2 are formed between the blocks

1. These rows of blocks 1 are then joined by the same insert 2 into sheets. The same insert 2 is glued to two adjacent side sides and the panel is pulled into the assembly frame to the prescribed format and left until the adhesive has dried.

In the frieze format, the same insert 2 is glued to two adjacent side faces of the blocks

1. The blocks 1 are manufactured, for example, from round logs 6, by cutting them into billets, from which the blocks 1 are punched. The second procedure is to make prisms 4 for the exact dimensions of the blocks 1 and cut by incision 5, e.g. blocks 1.

In the construction site, block parquet or block friezes are bonded to a flat hard base, for example concrete in asphalt mastics or other suitable adhesives. They are joined together by gluing the side insert with a quick-drying, eg rubber adhesive. They can also be underlayed as a backing, warm floor for working at machines, in shops at the counters, on stairs, corridors, etc.

Claims (1)

Block blocks of thin blocks of various wood, cross-cut, allowing impregnation over the entire block thickness, characterized in that the blocks (1j) are joined to each other by means of a flexible insert (2), e.g. cork, rubber or PVC, which is also provided on two outer adjacent lateral sides of the sheets or friezes and which forms grooves (3) on the bottom surface of the wheels of each block (11) for separately connecting each block (11) to the substrate.
