Mortise structure for floors

Abstract

The invention discloses a mortise structure for floors. The mortise structure comprises a tenon face (1) and a groove face (2) which are matched with each other, the upper portion of the tenon face (1) inclines inwards by 0.5 degree, the upper portion of the groove face (2) inclines inwards by 0.5 degree, the outer side end of the tenon face is a 45-degree chamfer, and the upper contact parts of the tenon surface (1) and the groove surface (2) are in surface contact. By means of the structure, when the floors are spliced, harsh noise cannot be generated when the floors are treaded even if thefit clearance between a tenon and a groove is slightly large, and the problem that the harsh noise is generated when the solid wood floors in the prior art are treaded due to the fact that the fit clearance between the tenon and the groove is slightly large is effectively solved.

Description

technical field [0001] The invention relates to a floor, in particular to a tongue and groove structure for the floor. Background technique [0002] At present, when the solid wood flooring we use is spliced ​​and installed, the tenons and grooves have an inward angle. The tenon surface is generally inwardly inclined by 4°, and the groove surface is generally inwardly inclined by 2°. The contact part between the tenon and the groove of the floor forms a gap. When the floor is spliced, the contact between the tenon and the groove is a straight line. Relative displacement occurs, the strength of the force on the contact surface increases, and harsh noises are generated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tenon-and-groove splicing structure of a solid wood floor, so that the installed solid wood floor will not produce harsh noises when stepped on. [0004] In order to solve the above-mentioned techn...

AI Technical Summary

Problems solved by technology

[0002] At present, when the solid wood flooring we use is spliced ​​and installed, its tenons and grooves have an inward angle, of which the tenon surface is generally inwardly inclined by 4°, and the groove surface is generally inwardly inclined by 2°, so that the The contact part of the tenon and the groove of the floor forms a gap. When the floor is spliced, the contact between the tenon and the groove is a straight line. If the gap between the tenon and the groove is slightly larger, it will cause the floor to be stuck between the boards when stepping on it. Relative displacement occurs, the strength of the force on the contact surface increases, and harsh noises are generated
