Problems solved by technology

Those skilled in the art usually use two methods of integrated and separated to form steel-wood composite structures, but this method of integrated combination usually does not take into account the difference between the Poisson's ratio of steel and wood, which will affect its further combined force Deformation ability; and in the steel-wood separation combination, wood and steel form a separate member to bear force, the structure tends to have uneven rigidity, and the wood member forms a weak link

Abstract

The invention relates to a steel-wood combination column and a combination method. The steel-wood combined column comprises profile steel and glued wood. The profile steel comprises cross-shaped steeland short straight-line-shaped steel; the cross-shaped steel is provided with four end parts; short straight-line-shaped steel is welded on two sides of each end part; short straight-line-shaped steel is welded to two sides of each end part of the cross-shaped steel and then the welded cross-shaped steel is in a T shape. The glued wood is clamped in the space between the cross-shaped steel and the short straight-line-shaped steel, the glued wood, the cross-shaped steel and the short straight-line-shaped steel are provided with preset holes corresponding to one another in position, and a plurality of sets of bolts penetrate through the short straight-line-shaped steel on opposite sides of the periphery, the glued wood and the cross-shaped steel between the straight-line-shaped steel to integrally lock and connect the whole. A rubber pad is clamped between the profile steel and the glued wood. The steel-wood combined column combines two materials of steel and wood, improves the mechanical property of steel-wood combined columns, prolongs the service life of connection, and gives play to the combination advantages.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a steel-wood composite column and a composite method. Background technique [0002] How to effectively use green and environmentally friendly materials, improve the mechanical properties of the structure, reduce the weight of the structure, and prolong the service life are frontier issues in today's social development. Among many structures, the composite structure is a structure that can effectively utilize the properties of materials and the advantages of components at the same time, so it has been widely used. At present, the combination of steel and wood is a relatively new form of combined structure. Among them, steel has high strength, uniform material, and flexible connection methods, but its stability and fire resistance are poor. In recent years, wood structures have been gradually applied in my country. The strength loss of wood under high temperature is small, renewabl...
