Abstract

The invention discloses a manufacturing method of an internally arranged thin-wall H-shaped steel and wood composite beam. The manufacturing method comprises the steps that epoxy resin adhesives are brushed on the two sides of a thin-wall H-shaped steel web and the inner sides of web wood plates, the thin-wall H-shaped steel web and the web wood plates are bonded and connected through web connecting bolts, and then thin-wall H-shaped steel and webs on the two sides are closely pasted through pre-tightening opposite-pulling devices; epoxy resin adhesives are brushed on the surfaces of thin-wallH-shaped steel flanges and the inner sides of flange wood plates, the thin-wall H-shaped steel flanges and the flange wood plates are bonded and connected through flange shear-resistant connecting toggle pins, and then the thin-wall H-shaped steel and the flange wood plates are closely pasted through the pre-tightening opposite-pulling devices; and finally, the internally arranged thin-wall H-shaped steel and wood composite beam is formed. According to the manufacturing method of the internally arranged thin-wall H-shaped steel and wood composite beam, efficient steel and wood compositing canbe achieved, the steel and wood composite beam with more excellent properties of bearing capacity, rigidity, durability and the like is formed, and industrial production and standardized constructionof the steel and wood composite beam in a steel and wood composite structure are facilitated.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a method for manufacturing a built-in thin-walled H-shaped steel-wood composite beam that combines steel and wood and is suitable for steel-wood composite structures and wood structures. Background technique [0002] Wooden structures have a long history and a long history in our country. At present, there are still a large number of ancient wooden structures, and a large number of wooden structures are still being built in vast villages, ethnic villages and tourist attractions. The growth cycle of wood is long. With the consumption of wood resources, wood will face the danger of shortage, and the price will inevitably rise, which will restrict the development of pure wood structures. At the same time, the low elastic modulus of wood itself, its mechanical properties are greatly affected by creep, its strength degrades, and it is prone to cracks and other ...
