Circular arc locking buckling floor board

Abstract

The invention discloses a circular arc locking buckling floor board. A clamping tenon and a first side face are arranged at one end of the floor board. The clamping tenon comprises a tenon head, a second side face and a tenon body. The tenon head protrudes out of the second side face and is connected with the tenon body into a whole. The tenon head comprises a section of first circular arc face. The tenon body comprises a section of second circular arc face. The first circular arc face and the second circular arc face are connected into a whole. A groove is defined by the clamping tenon and the first side face. A third side face and a wedge block are arranged at the other end of the floor board. The wedge block protrudes out of the third side face. A clamping groove is defined by the third side face and the wedge block. The clamping groove comprises a groove head and a groove body. The groove head is located inside the clamping groove. The clamping tenon and the clamping groove are matched, the tenon head and the groove head are matched, and the tenon body and the groove body are matched. The circular arc locking buckling floor board is simple in paving, high in paving efficiency, firm in floor board combination, not prone to occurrence of a looseness phenomenon in the process of use, moisture-proof and capable of preventing the floor board from deformation or decay caused by moisture absorption.

Description

technical field [0001] The invention relates to the field of decorative building materials, in particular to a floor with arc locks. Background technique [0002] Wooden floor has advantages such as natural, environmental protection, attractive in appearance, luxury, etc., along with the continuous improvement of social living standard, wooden floor is more and more widely used in the places such as family, hotel. Wooden floors are generally connected by buckles. There are many types of floor buckle structures, mainly including flat buckles and lock buckles. Because the solid wood floor is easy to absorb moisture and expand during use, lose water and shrink, resulting in arching and large expansion joints. The flat button floor usually needs to be glued or nailed to fix the floor during the paving process. The paving process is very troublesome and wastes manpower. At the same time, it is easy to damage and dirty the floor during the paving process. However, after a period...

Problems solved by technology

In this way, the fit between the tongue and the groove is too tight during installation, and there is no buffer space for the deformation of the floor. On the contrary, in the future use of the floor, the deformation of the floor will not be released under the condition of shrinkage and swelling, which will easily cause the floor to deform. arching deformation and loosening
