Description

Prefabricated Flooring Materials

The present invention relates to a prefabricated flooring, and more specifically, to one side of the floor having a rectangular plate shape and the other side opposite to the installation is installed at a certain angle for engagement to the fastening protrusion and the fastening groove is fastened by engaging, It relates to a prefabricated flooring material that can be easily coupled to each other by forming an insertion protrusion and an insertion groove to be inserted into each other in a vertical direction simply to each other side is not formed with the fastening protrusion or fastening groove. .

In the past, an integrated floorboard was used on an indoor floor of a building, but in recent years, when building a floor with increasing interest in an indoor interior, it has become common to decorate an indoor floor by connecting block-shaped flooring materials of a certain size to each other.

In particular, the wood or synthetic resin is mainly used as the flooring material, the wood flooring is relatively vulnerable to the external environment is increasing the use of the flooring of the synthetic resin material.

In general, the indoor floor is constructed using the flooring, and a method of applying the adhesive to the upper surface of the indoor floor structure and then attaching the block-shaped flooring material to the floor is mainly used. In this case, an adhesive of epoxy, urethane or acrylic series is used as the adhesive.

However, when the adhesive is applied to the upper surface of the indoor floor structure described above, volatile organic compounds and the like are released from the adhesive, which may cause residents to cause sick house syndrome, and the condition of the floor of the building is poor or moisture on the floor. If it contains a weakened performance of the adhesive has a problem that it is difficult to maintain a stable state of construction of the synthetic resin flooring material.

In order to solve this problem, a construction method that does not adhere the flooring to the base using an adhesive has recently been developed.

On the other hand, the flooring that is installed on the floor of the building is constructed in such a way that the flooring having the same shape is assembled so as to be connected to each other, for this purpose, each of the flooring projections and the projections are connected to each other is inserted into the projection groove It is formed on one side and the other side opposite thereto.

As an example of such a flooring material, WO 2007/015860 is a system for connecting a plurality of flooring materials, the cross section is curved in the form of "S" so that each side can be fastened to each other on one side of the plank and the other side opposite to it. A system for connecting a flooring material and a flooring material is disclosed by forming a curved projection and a groove into which the projection is inserted, and inserting and fastening the curved projection at an angle to the groove.

However, in the prior art, since the edges are formed on the sides of the flooring material with the curved protrusions and the grooves formed on the sides of the flooring material, offsets are formed and fastened to each other. There is a problem in that the fastening force between the flooring material is relatively weak to each other coupled to each other, the position of the flooring material is changed during the construction of the flooring material is not only inconvenient to the construction, but also the construction of the flooring can be distorted after construction.

The present invention has a problem to be solved when the floor surface is installed by connecting a plurality of flooring to each other, each flooring is easily engaged with each other, and the combined flooring to maintain a stable binding force to each other.

The present invention is derived to solve the above problems, the plate-shaped body portion;

A fastening protrusion formed along one side of the body portion, the cross section of which is bent starting from one side and finished to bend the curved end;

A fastening groove formed along the other side opposite to one side of the fastening protrusion, the cross section having a shape corresponding to the fastening protrusion so that the fastening protrusion can be inserted into the fastening protrusion;

A first insertion protrusion formed along one side of the body portion in which the fastening protrusion and the fastening groove are not formed, the cross section being spaced apart from a lower side of the side of the body portion by a predetermined distance, and vertically projecting upwardly from the spaced end;

It is formed along the other side opposite to one side provided with the insertion protrusion, the cross-section is spaced apart from the upper end of the side of the body portion so that the insertion projection can be inserted, protruding vertically downward from the spaced end There is a problem solving means to provide a prefabricated floor covering comprising two insertion protrusions.

The present invention has the effect of simplifying the construction by allowing each flooring to be easily interlocked with each other when installed by installing a plurality of flooring, in particular, prefabricated flooring to each other.

The present invention plate-shaped body portion;

A fastening protrusion formed along one side of the body portion, the cross section of which is bent starting from one side and finished to bend the curved end;
