Description

TECHNICAL FIELD The present application relates to a board joining method, in particular to a board splicing edge structure and splicing assembly, and also to an assembly method.

As a natural material, wood has good ventilation and environmental protection and sufficient support strength, and if a virtuous cycle of tree planting can be established, it can also be used as a continuous building material. As evidenced by the facts, in terms of fire protection, the fire resistance performance of wooden beams and columns is no worse than that of steel structures. With people's increasing awareness of environmental protection and demand for housing, wooden building structures are becoming more and more popular. As a plate building, the wallboards or roofs require large plate members, which can reach several meters in length to facilitate quick construction on site. Therefore, it is an important part of promoting the development of wooden construction how to make the plate materials to be joined relatively strong and easy to construct.

At present, there are metal joints, wood screw joints, mortise and tenon joints, etc., as joining and fixing methods for large plate materials and wooden structural walls. , the operation is inconvenient, the overall strength is low, and the durability performance is relatively poor.

The advantage of a tenon-and-mortise joint is that the tenon and mortise are firmly butted, usually an interference fit or transition fit (transitional fit), and the joint is robust. However, when mortise joints are processed on large-sized plates or walls, since the size of the plates is relatively large, it is necessary to lift them with a crane when assembling. Also, since the tenon joint requires a tight joint, it is difficult to manipulate when lifting a large board or wall to butt and secure the tenon joint. For relatively long plate joining edges, it is necessary to ensure that the tenon joint is firm and that there is no accumulated error even if the length is several meters, so when joining two plates together Secondly, it is necessary to apply an external force to hammer the splice joint, but in practice, this can hardly be realized. Even with conventional dovetail groove and dovetail tenon structures, there is the problem of difficulty in butt jointing as described above.

Another problem with plate joining structures is that the two plates that join together are locked together in one direction, but are prone to disengagement in other directions. For example, in the case of the conventional dovetail groove and dovetail tenon structure, it is locked in the vertical direction, but it is easy to come off in the horizontal or vertical direction. If three-dimensional locking can be achieved after splicing, a relatively ideal joining structure will be obtained.

SUMMARY OF THE INVENTION The present application provides a plank insert joint structure that is convenient for building construction to address the deficiencies existing in the prior art described above.
