Sectional Flooring with Coupling Member, and Assembling Method Thereof

Abstract

Sectional flooring is provided. The sectional flooring includes first, second, and third floor boards (10,20 and 30) and a coupling member (40) for connecting the first and second floor boards (10 and 20) that are arranged to be adjacent to each other in a longitudinal direction. The coupling member (40) includes a base portion (41) placed over-adjacent first and second floor boards (10 and 20), a pair of side hooks (42) protruding from opposite ends of the base portion (41) toward top surfaces of the first and second floor boards (10 and 20), and a pair of cantilever hooks (43) spaced apart from each other by a predetermined distance and protruding from a center of the base portion (41). Each of the cantilever hooks (43) includes a hook step (431). The hook step (431) includes an upper portion formed with an inclined surface inclined at a predetermined lead angle (OL) and a lower portion is formed with an inclined surface inclined at a predetermined return angle (OR).

Description

TECHNICAL FIELD[0001]The present invention relates to sectional flooring. More particularly, the present invention relates to sectional flooring with a plurality of floor boards that can be securely coupled to each other by an elastic coupling member, and a method of assembling the same.2. BACKGROUND ART[0002]Generally, sectional flooring is formed with a plurality of floor boards each having a predetermined dimension, which are made separately, and assembled together on the floor of a building. In the conventional sectional flooring, each of the floor boards is formed in a rectangular shape having a pair of longitudinal sides and a pair of lateral sides. Each of the floor boards is provided at longitudinal or lateral sides with a coupling structure by which the floor board can be coupled to another floor board.[0003]That is, the coupling structure includes at least one protrusion and at least one recess. Therefore, the two adjacent floor boards are assembled with each other by the ...

AI Technical Summary

Benefits of technology

[0018]According to the present invention, since the lateral sides of the floor boards are coupled to each other by the coupling member having the above-described structure and material property, the coupling force between the flooring boards can be enhanced and thus the gap and step difference between the floor boards can be suppressed even when the floor boards can contract because of floor heating. Furthermore, since no damage such as a crack occurs on the coupling portion during the assembling process of the sectional flooring, the endurance of the section flooring can be enhanced.

Problems solved by technology

However, such a fixing technique has disadvantages in that it is difficult to remove the floor boards from the floor of the building, and an epoxy-based adhesive that is harmful to the human body should be used.

However, in case the adhesive is frozen or used after long-term storage, the adhesion force of the adhesive is deteriorated.

Further, when the adhesive is not properly applied to the floor boards, a gap or a stepped difference may be formed between the floor boards.
