Bamboo and wood combined hollow flat beam

Abstract

The invention provides a bamboo and wood combined hollow flat beam which is jointly composed of horizontal bamboo and wood combined box beam blocks, vertical bamboo and wood combined box beam blocks and L-shaped beams. The horizontal bamboo and wood combined box beam blocks, the vertical bamboo and wood combined box beam blocks and the L-shaped beams are bonded together through E1-level phenol glue. Each horizontal bamboo and wood combined box beam block is composed of multiple specially-shaped I beams. Each vertical bamboo and wood combined box beam block is composed of multiple specially-shaped I beams. Each specially-shaped I beam is composed of a specially-shaped web and a thin long beam. The two ends of each specially-shaped web are bonded to the edges of the corresponding up-down staggered thin long beams through the E1-level phenol glue. In the bamboo and wood combined hollow flat beam, used materials are bamboo and wood materials, the thin long beams and the L-shaped beams aremade of recombined bamboo, and the specially-shaped webs are made from OSBs; the flat beam is hollow inside and good in environmental protection property and economical efficiency; the flat beam is manufactured in a box beam mode, so that the flexural property of the flat beam is improved; the flat beam can bear shear force in the mode of the flat beam, and practical significance for building clearance improvement is achieved; and the flat beam is simple in structure, easy to produce and capable of being used in a beam structure in a wooden structure building.

Description

technical field [0001] The invention relates to a bamboo-wood composite hollow flat beam, which is applied to beam components of various light wooden bridges and bamboo-wood buildings, and belongs to the field of civil engineering. Background technique [0002] my country has abundant biomass resources. Bamboo has the characteristics of strong reproduction and regeneration ability, short growth cycle, and excellent material. With the promotion of bamboo and wood structures in my country, bamboo and wood structures, especially bamboo structures, have gradually been accepted and loved by the public. However, in the existing bamboo structures, the beam members made of recombined bamboo are rarely used in buildings, and most of the member cross-sections have a single form. In the bamboo-wood structure, in order to create a large-space architectural form, the headroom height of the building is also very important, so in this case, by changing the cross-sectional form of the beam ...

Problems solved by technology

However, the inner and outer steel sleeves set up to increase the rigidity increase the weight of the entire member, and the excessive height of the beam section also makes the beam member difficult to be sheared and easily unstable
