DE19834324C1 - Parquet floor for building has recessed blocks fitting onto support grid - Google Patents

Abstract

The parquet floor for a building has connected massive wooden blocks with each block (6) connected to adjacent blocks by a grid (2) of rods. The grid rods are secured in the blocks by pressure buttons without the use of glue.

Description

The invention relates to a solid wood parquet floor for floating installation according to the preamble of claim 1)

It is known that country house planks or plane planks on wooden ceiling beams or massive ceilings on wooden supports with nails, screws or clips, Country house floorboards made of chipboard or plywood with veneer floating in stock  wooden or screed.

Parquet made of solid wooden slips, bars or slats made of wood such as Oak, beech, pine, ash and other hardwood and coniferous woods, all shapes made of solid wood are laid with parquet glue, rarely with nail technique. Board and finished parquet, solid or veneered, is used according to the state of the art Parquet glue glued to appropriate sub-floors. Conclusion: all solid parquet floors are mainly glued on, some nailed or screwed, however not laid floating. If you take the life cycle assessment into account, everyone is behind State of the art glued solid wood parquet foot available on the market Floors and floors made from planks, chipboard or plywood Veneer are made the same. There are large amounts of glue on these floors consumed. The moisture in the subfloor is crucial for gluing problems occurring, it can e.g. B. with glued floors no guarantee be taken if the residual moisture in the screed floor is not exactly what is required Number when laying. However, this is a factor that depends on nature. Moisture from the adhesive also gets into the wood on the floor. By air or other moisture, the wood swells or shrinks Joints can no longer be closed and there is no arching of the floor more avertable. Whole single pieces of wood are also torn from the adhesive or screed. Therefore, if you don't have to stick, you have facts like residual moisture, Outgassing has nothing to do, there are fewer operations.

Expansion is a natural thing, only the system must be able to expand.  

A floating floor must be system-fixed in relation to the sub-floor his. This means that no frictional force may arise. The replacement of individuals Parts after laying have no bad results with tongue and groove elements not possible. The prior art floors, which are system-fixed, are floors glued on screed, with their above defects.

A floating floor must also be system-fixed, why? When a floating floor is expanded, pressure and pressure develop Shear forces in every direction that cannot be prevented, the floor stretches depending on the fluctuations in humidity, it gets bigger. When shrinking this process is reversed, the floor contracts, it becomes smaller. This process is repeated continuously as long as the floor is not loaded. However, if the furniture brings heavy loads to the floor, then if he is held at the load points, fixed, he can no longer get together pull. The result is, it becomes vulnerable to fluctuations in humidity pulled apart because he has no return and it always arises larger joints and then bulges because the floor is no longer can contract.

There are many disadvantages with prior art systems. The lack of return for example. Others are not fixed to the sub-floor. The recyclability of a floor, the more adhesive, the worse the ecological balance. The short lifespan of the systems is also a factor in a poor ecological balance. With all of these prior art facts described above, however, can  the catalog of requirements for the title cannot be met technically.

This object is achieved according to the invention by a floor, as defined in the characterizing part of claim 1).

Contrary to the prior art, the floor according to the invention becomes perfect made without glue. It is made from relatively small solid woods, this is an economic and ecological advantage.

The floor has a total grating that extends either from the connection sockets 1 , 15 , or 20 , a perfect angular speed, or the extraordinarily important factor, which guarantees counter-pull in the floor. All floor timbers are used from above, this is a crucial point for easy installation and the type of attachment by plugging in from above complies with the main load on the floor from above.

All possible floor patterns 30 , over solid wood 6 , or panels 7 , rectangular or polygonal, also round shapes, inlays, can also be conceptualized or put on.

Full recycling, even humification is possible, the ecology is perfect Taken into account.

Drawings in greatly simplified versions serve to explain the inven dung.

Show it:

Fig. 2 shows the assembly of the connection socket 1, and individual catch mechanisms possible foundations 2.

Fig. 3 shows a section through a connection socket 20 with catch mechanisms foundation 2 for insertion of the plates 7 of solid wood or 6 by push-button pin 10 and snap mount 11.

FIG. 4 shows a section and top view of the parquet floor when using the connection frame 15, the open top version 28 .

Fig. 6 is a section and top view of the parquet floor with the use of the connection socket 15 closed at the top type 29.

The state-of-the-art flooring is still considered today: the sub-floor is the only decisive factor for the stability of the floor in the direction of the surface, it was simply glued or nailed on. In the flooring according to the invention, the subfloor has only the supporting function. On it, the connection versions 1 , 15 , 20 are the basis for a system fixation of the floating solid wood parquet floor compared to the underfloor screed 33 or a wooden structure. So that the connection frames 1 , 15 , 20 have the expansion of the sub-floor and are in relation to it, they are made accordingly in steel 31 for reinforced concrete, or in wood for a sub-structure made of wood, or with material combinations such as plastics or aluminum.

The solid wood 6 is fixed in place by pushing on or pushing it in via the grid pegs 2 accommodated in the connection sockets. This and the choice of a sufficient joint dimension 32 prevents the joints from adding up if the wood swells too much when there is a change in air humidity, because only one fixed individual wood can expand relative to the other and thus prevents the floor from arching.

The assembly or laying of the floor according to the invention happens as follows:

The parts 4 u. 5 in the composite half offset over the holes 21 , the grid pin 9 and the grid pin 2 of the connection socket 1 joined together.

Then either solid wood 6 or plates 7 are plugged into the bore 13 , the bore 23 and grid pin 9 and connected via the locking cross pin 39 . Now the version with the connection socket according to the push button system 3 . The same series of processes applies here, only the solid woods 6 and plates 7 are joined together by pushing on the push button pin 10 and push button socket 11 via the bore 13 . When using the connection socket 15 , the parts 9 , 16 , 17 , 18 and 19 are assembled via the bores 22 , 23 , 24 , 26 and 27 to form the overall grid 34 'and then the factory-made plates 7 with connection socket 1 or 20 according to the push-button strip system 35 indented. With this version you can still choose between the 28 open or closed 29 versions or plates 7 with 20 connection.
