Wood pin half-tenon joint reinforced by self-tapping screws and manufacturing method of wood pin half-tenon joint

Abstract

The invention provides a wood pin half-tenon joint reinforced by self-tapping screws. The wood pin half-tenon joint reinforced by the self-tapping screws comprises a first wood member with a mortise opening and a second wood member with a tenon; a group of rift grain self-tapping screws are arranged in the axial direction of the tenon on the second wood member in the rift grain direction in a drilling mode, and a group of cross grain self-tapping screws are arranged at the positions, in the cross grain direction, perpendicular to the axial direction of the tenon in a drilling mode; a group ofcross grain self-tapping screws are arranged at the positions, located on the two sides of the mortise opening in the cross grain direction, on the first wood member in a drilling mode; and a corresponding pre-drilling hole is perpendicularly formed in the corresponding position of the tenon and the mortise opening, and a wood pin is inserted into the pre-drilling hole. The wood pin half-tenon joint reinforced by the self-tapping screws has enough initial rigidity, flexural bearing capacity and deformation capacity, prevents the tenon from being broken and damaged and wood cross grain from being split off and damaged, and the stress capacity of the joint is improved.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the reinforcement and transformation of traditional wooden structures, especially the maintenance and reinforcement of mortise and tenon joints. Background technique [0002] The application of wood as a building material has a long history in our country. There are various types of traditional wooden structures, which account for a large proportion of ancient Chinese buildings. Mortise and tenon joints are one of the commonly used forms of component connection in traditional wood structures. Different from concrete structures and steel structures, traditional Chinese wooden structures usually exhibit the characteristics of "strong components and weak nodes", so nodes are the focus of this type of structural system. [0003] Under the action of horizontal load, the mortise and tenon joints of wooden pins are prone to brittle tenon fracture and wood transverse grain splitting. ...

Problems solved by technology

[0003] Under the action of horizontal load, the half-tenon joints of wooden pins are prone to brittle tenon fracture damage and wood transverse grain splitting damage

This makes the bearing capacity and deformation capacity of such nodes not fully utilized
