Description

Connecting tenon

Technical Field

The invention relates to the technical field of buildings, in particular to a connecting tenon.

Background

The mortise and tenon joint method for connecting all the components in the manufacturing of the building upper plate is a main structural mode for manufacturing various shapes. Various mortise and tenon joint methods are different in application range, but all have the joint function of a physical structure.

If the mortise and tenon joint is properly used, the two wood structures can be tightly buckled, and the seamless degree of the costume is achieved. Several tens of different mortise and tenon joints are classified according to constructional cooperation, and can be roughly divided into three types: the combination of the two sides can be the combination of the two sides or the combination of the two sides. Such as a notch tenon, a tongue-and-groove tenon, a dovetail tenon, a threading tenon, a binding tenon and the like. The other is a point structure method, which is mainly used for transverse and vertical T-shaped combination, angulation combination, cross combination and extension combination of straight materials and arc materials. There is also a construction method of combining and connecting three members to each other, which is a more complex and special method than the above tenon-and-mortise joint structure.

The splicing of the plates is mainly divided into 45-degree and 90-degree splicing according to the angle of the splicing surface, and is mainly divided into detachable connection and non-detachable connection according to the installation and detachment modes.

However, many products are not 90 degrees spliced, for example, 45 degrees spliced on the 01 spliced surface of the plate is required, as shown in fig. 2, if the products are connected by using the round tenons 00, the connection strength is insufficient due to shallower wood tenons.

Therefore, the connecting tenon is convenient to install, firm and reliable, can be used for splicing the splicing surfaces of the plates at other angles except 90 degrees, and is a problem to be solved in the field.
