Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to a beam-slab connection method and structure. Background Art

[0002] China is rich in bamboo resources. The prefabricated building profiles made of bamboo resources at present have good mechanical properties and are rare green and low-carbon building materials. The application mode of round bamboo in building structures is mainly round bamboo landscape buildings, which have good ornamental properties. However, since round bamboo belongs to a raw material with a cavity structure, its stress is complex, and the connection between round bamboos and between round bamboos and other materials requires the aid of special connection devices, which greatly limits its application in construction.

[0003] An assembled building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through a reliable connection method. The building mainly includes precast concrete structures, steel structures, modern timber structures, etc. Because of its standardized design, factory production, assembled construction, information management, and intelligent application, it is a representative of modern industrial production methods.

Among them, the top plate is located at the top of the wallboard, the first side plate is fixed at one end of the top plate, the second side plate is fixed at the other end of the top plate, and the wallboard is clamped and fixed between the first side plate and the second side plate. The end of the third side plate is fixed to the side of the second side plate, and the end of the floor slab is lapped and fixed on the third side plate. This connection node can realize the fixed connection between the wallboard and the floor slab. However, the above connection node can only be used in bamboo-based buildings with low bearing capacity and no cross beam, and it is impossible to complete the tight connection of the wallboard, cross beam and floor slab in a building with a cross beam, which has limitations.
