Connecting mechanism of solid wood floor blocks for radiant ground heating and machining method thereof

Abstract

The invention provides a connecting mechanism of solid wood floors. The solid wood floors comprise floor bodies. The connecting mechanism comprises tenons and mortises, wherein the tenons and the mortises are mutually buckled and machined on the two sides in the length direction of the floor bodies. The tenons are provided with first convex blocks, second convex blocks and third convex blocks which protrude out in the width and thickness directions of the floors correspondingly, and the mortises are provided with first grooves, second grooves and third grooves which are sunken in the width andthickness directions of the floors correspondingly. The first convex blocks and the first grooves are mutually buckled, and expansion gaps exist after tight buckling; the second convex blocks and thesecond grooves are mutually buckled, and expansion gaps exist after tight buckling; and the third convex blocks and the third grooves are mutually buckled, and expansion gaps exist after tight buckling. Conical gaps are formed in the upper corner areas of the tenons and the mortises.

Description

technical field [0001] The invention relates to the field of solid wood floors, in particular to the field of locking solid wood floors used in floor heating environments. Background technique [0002] Typically, floor boards are connected in the following ways: [0003] The first connection method is tenon joint (flat buckle) connection. When the wooden floor is paved, the connecting parts formed by the tenon (tongue) and the groove are combined with each other between the floors. This is also the most commonly used connection method for solid wood flooring. This connection method is relatively loose. Usually, the keel method is used for paving or the tenon and groove are bonded together with adhesives and the suspension method is used for paving. In the underfloor heating environment, the keel method is not conducive to heat transfer, and there will be a problem of formaldehyde pollution in the sizing suspension pavement. If the adhesive connection is damaged, it will ca...

AI Technical Summary

Problems solved by technology

In the underfloor heating environment, the keel method is not conducive to heat transfer, and there will be a problem of formaldehyde pollution in the sizing suspension pavement. If the adhesive connection is damaged, it will cause damage to the floor

[0004] The second type of connection is the joint connection, that is, between the floorboards, by means of connecting elements made of metal, but this connection is expensive and their preparation and installation are time-consuming

[0007] Compared with other laminated wood flooring (such as laminate flooring or solid wood composite flooring, the dimensional stability in all directions tends to be consistent through the reorganization of wood fibers or the crisscross gluing of veneers), due to the anisotropy of solid wood flooring, especially The dry shrinkage rate and wet expansion rate in the width direction are large. If the shape design of the solid wood floor lock is unreasonable and the moisture content changes, it will either be inconvenient to install, or the structure will be loose after installation and easy to fall off, or the floor buckle will be caused by dry shrinkage and wet expansion. type damage, resulting in unusable floors or noise, etc., the test of the strength of the lock connection is more severe in terms of dimensional stability
