Problems solved by technology

However, in this utility model, the self-tapping screws are directly connected to the vertical wooden column and the horizontal connecting beam, which is subject to a large force and is prone to shear failure, and the self-tapping screws are located on the side of the component, which has a great impact on the appearance of the component
In addition, this joint is only applicable to planar wooden frame members, but not to three-dimensional frames where wooden columns need to be connected with beams in the out-of-plane direction (perpendicular to two transverse wooden beams), so it is difficult to apply in modern wooden structure systems

Abstract

The invention relates to a wood structure assembly type self-tapping screw and bolt combined joint. The wood structure assembly type self-tapping screw and bolt combined joint is characterized by comprising a first wood component (1), a second component (2), a metal connecting piece (3), a bolt (4) and a self-tapping screw (5), one face of the metal connecting piece (3) is connected with the second component (2) through the bolt (4), the other face of the metal connecting piece (3) is connected with the first wood component (1) through the self-tapping screw (5), and the first wood component (1) and the second component (2) are connected with each other through the metal connecting piece (3). Compared with the prior art, the wood component in the joint does not need slotting, steel filling plate adding and the like, the wood structure assembly type self-tapping screw and bolt combined joint has the advantages of being convenient to construct, simple, effective and the like, meanwhile, the self-tapping screw is obliquely driven in, pull-out damage is avoided to a certain extent, the bearing capacity is improved, joint damage is avoided, and the joint stability is improved.

Description

technical field [0001] The invention relates to the technical field of civil construction engineering, in particular to an assembly type self-tapping screw and bolt combined node of a wooden structure. Background technique [0002] Wood is a natural and very friendly material, and is considered to be the preferred building material for "green buildings", and modern wooden structures are a structural type of "energy saving, land saving, and ecological protection". The joint properties of wood structures directly affect the structural strength, service life and reliability. At the same time, wood has disadvantages such as low tensile strength, easy splitting, and strength changes with moisture content. important link. [0003] At present, steel splint connection, hidden steel plate connection or planting bar connection are mostly used for wood structure node connection, but there are many shortcomings in using the above node connection methods. For example, it is difficult t...
