Axial tension and compression composite force type prefabricated wood strut

Abstract

The invention discloses an axial tension and compression composite force type prefabricated wood strut. The axial tension and compression composite force type prefabricated wood strut comprises steelend plates, a wooden strut body, pull rods, nuts and steel pins; the steel end plates are installed at both ends of the wooden strut body; connecting lug plates used for connecting the prefabricated wood strut with other components are welded to the outer sides of the steel end plates, and shearing plates or shear-resistance steel plates resisting the shearing force applied to the end parts of thewood strut body are welded to the middle parts of the inner sides of the steel end plates; and long round holes are formed in the positions, corresponding to screw holes, of the strut in the longitudinal direction, the pull rods penetrate the long round holes, the end parts of the pull rods penetrate through pre-formed screw holes on the steel end plates, threads are arranged on the end parts ofthe pull rods, and the pull rods and the steel end plates are fixed through nuts. The axial tension and compression composite force type prefabricated wood strut is mainly used for solving the problemthat end part connecting joints and the strut have insufficient tensile strength and are prone to cracking when the wood strut is in tension state or compression state under different working conditions, and the assembly process can be completed at the factory, and has the advantages such as high compression resistance and high tensile strength, simple and reliable end part joint structure, and high degree of prefabrication.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a prefabricated wooden brace of an axial tension-compression composite force type. The pull rod inside the wooden brace mainly bears the axial tension of the wooden brace, and the wood itself bears the to pressure. Background technique [0002] Wood is a natural, environment-friendly material and is considered the preferred building material for "green buildings". Wood is beneficial and harmless to the environment in the process of generation, production, use and disposal. The application of wood to buildings can effectively reduce the comprehensive energy consumption of buildings and the negative impact of buildings on the environment, which is conducive to the construction of an environmentally friendly society in my country. [0003] With the gradual popularization of wooden structure buildings, the structural forms adopted are becoming more and more c...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of the existing connection structures, such as the cumbersome structure and low efficiency of the wooden structure nodes in the tension-compression compound stress, and to provide an axial tension-compression compound stress type prefabricated wooden strut, which has the Strong tensile and compressive capacity, beautiful and reliable joints, high degree of prefabrication, etc., the present invention adopts steel end plate transition through tie rods to resist tension and wood, and the force is clear, which is convenient for structural design checking and calculation
