Inverted T-shaped steel-wood-concrete composite beam and construction method thereof

Abstract

The invention discloses an inverted-T-shaped steel-wood-concrete composite beam and a construction method thereof. The inverted-T-shaped steel-wood-concrete composite beam comprises a reinforced concrete plate and an inverted-T-shaped steel beam, and the top of a web of the inverted-T-shaped steel beam is fixedly embedded into the reinforced concrete plate; grooves are defined by the two sides of the inverted-T-shaped steel beam and the bottom side of the reinforced concrete plate correspondingly, and the grooves are fixedly filled with wood beams. When the inverted-T-shaped steel-wood-concrete composite beam bears load, the inverted-T-shaped steel beam and the wood beams bear tensile force, pressure is mainly borne by the reinforced concrete plate, and the advantages that the tensile strength of the wood beam and the inverted-T-shaped steel beam is high and the compressive strength of the reinforced concrete plate is high can be brought into full play; the integrity is good, the bearing capacity of the composite beam can be greatly improved, and the deflection is reduced; the structure is simple and assembling is easy; due to the existence of the wood beam, the direct fire area of the inverted-T-shaped steel beam in a fire disaster is reduced, and the fire resistance is greatly improved.

Description

Technical field [0001] The present invention relates to the field of composite beam structure, and particularly relates to an inverted T-shaped steel - wood - concrete composite beams and construction method. Background technique [0002] As a traditional reinforced concrete building construction, it requires a lot of resources and serious damage to the environment. In the country to promote ecological civilization construction and sustainable development in the context of a series of policy guidelines to speed up the rapid development of green buildings is gradually put out, which clearly requires that each region should vigorously promote the development of the wood structure. Wood as a renewable natural material, drawing easy, environmental pollution. In addition to wood absorb carbon dioxide during the growth process, the molding process of the process is only a small amount of carbon dioxide generated. [0003] Although wood has a high tensile strength, compressive strength ...
