Description

Concealed pressing lock buckle connecting piece and grooved wood floor

Technical Field

The utility model relates to a novel technology for paving a wood floor by utilizing a hidden connecting piece, in particular to a wood floor and connecting piece structure which can be assembled by vertical pressing and clamping.

Background

At present, a plate with a supporting structure is connected in a hidden mode, and a more convenient practical technology does not exist.

Typical common working scenarios are, for example, assembled wood floors with uniform length, width, thickness, including flat-mouth boards, tongue-and-groove boards, and latch boards. The flat-mouth boards are floors with the same standard processing and the edges are flush, and can be directly adhered to cement floors or joinery boards by glue. Although it is possible to directly construct vertically when dismantling or replacement occurs, this type of technology is now applied slightly, since the joint treatment is difficult to meet the construction requirements. The installation of the grooved floor is dependent on the glued floor between the tenon and the mortise, the back surface is provided with an anti-deformation groove, the anti-deformation groove is mutually overlapped when paved, the common grooved floor is required to use special waterproof special glue when being installed, otherwise, the floor can crack, but the tenon and the mortise of the common grooved floor are easy to wet and expand due to uneven construction gluing on the installation site. The locking floor is a floor with tenon and mortise which are correspondingly arranged at opposite edges and can be matched with each other, and a locking structure which is difficult to crack is automatically formed after the locking floor is assembled.

The lock catch is a structure for connecting the floor blocks through the physical force action of the inverted tenons. The locking force of the lock catch is mainly dependent on the connection force of the tongue and groove of the floor. The tensile force that the latch floor can bear is related to the chamfering angle and the chamfering area. Because the locking process has relatively high manufacturing difficulty and the slotting equipment is relatively expensive, the price of adopting the locking to connect the floor is relatively high. For the paving method of the wood floor, based on the limitation of the existing wood floor structure and paving method, the paving pattern is limited, and the I-shaped paving, the herringbone paving method and the fishbone paving method are mainly adopted, and when the limited various other field-shaped splicing methods and the like are spliced, the construction cost is high, and the inconvenience is caused. To solve the above problems, there are few new technologies disclosed successively.

In the technical schemes, the structures of the floor side grooves and the corresponding connecting pieces are researched, so that the installation convenience and the connection strength of the lock catches are improved at the same time, the tradition that two adjacent floor layers can be spliced in an opposite way only by paving common I-shaped patterns can not be eliminated on the premise of ensuring the tight structural strength of the connecting joint, and the mortise lock catch structure can be installed although the construction is inconvenient; for wood floors with herringbone, fishbone and hexagonal patterns, the locking structure is difficult to construct, and under the condition of symmetrical even sides, only two non-locking mortise and tenon edge structural forms can be tried, wherein one is respectively and continuously arranged, and the other is arranged at intervals between adjacent sides. The polygonal floor can not use the lock catch structure, only can use the flat mouth to beat the glue to fix in the prior art, and the installation effectiveness is low, with high costs, cost of maintenance is high. What is unavoidable in the existing locking structure is that the direction of each floor must be correctly placed according to the splicing requirements during typical splicing construction.
