The invention relates to a built-in reinforcing steel bar recombined bamboo concrete joint continuous beam and a construction method. Full-length reinforcing steel bars are arranged in a recombined bamboo beam, the rigidity and the bearing capacity of the beam are improved, the reinforcing steel bars at beam ends extend outwards and are reliably connected through straight thread sleeves to form the continuous beam, and the bending moment distribution of an internal force borne by the beam is changed into the continuous beam from a simply supported beam. The stress state of the beam is improved, so that materials are saved. Therefore, the butt joint of the recombined bamboo beam is made into a rigid connection mode, the simply supported beam is converted into the continuous beam, the bending moment distribution of the beam is more reasonable, the material performance is fully utilized, the purpose of reducing deformation or increasing spans is achieved, and the engineering application range of the recombined bamboo beam is widened.
Description
Technical field[0001]The present invention relates to the technical field of bamboo wood structure in civil engineering, and more particularly to a continuous beam and construction method of built-in steel recombinant bamboo concrete nodes.Background technique[0002]Compared with the wood, bamboo has the advantages of green natural, high strength, good toughness, short growth cycle, is known as "plant steel", and various structural projects have emerged in recent years, such as recombinant bamboo and glue bamboo. Wait. Recombinant bamboo is a bamboo new material to reorganize the bamboo and strengthen the shape of the bamboo, so that bamboo is processed to grow strip bamboo, bamboo or crushing into a bunch of bunch, after drying, then dip, then dry to require water content Then, it is then placed in the mold, which is formed by high temperature and high pressure heat. Compared with natural bamboo, the recombinant bamboo has the advantages of green environmental protection, high mater...
