Description
Technical Field
The invention relates to the field of industry and civil engineering, in particular to a laminated wood structure beam-column-wallboard integrated assembly and connection device.
Background
The assembled laminated wood structure is one of important directions of development of building structures in China, wood is used as a natural resource with renewable characteristics, and recycling can be realized. Compared with the traditional reinforced concrete structure, the assembled laminated wood structure is beneficial to the industrialized development of the buildings in China, saves energy, has the characteristic of high production efficiency, and is one of important ways for developing green and environment-friendly buildings. The connection node is one of key technologies of the assembled laminated wood structure, and the reliable, effective and convenient connection node is a key for guaranteeing the structural integrity and the earthquake resistance. The node connection in the assembled laminated wood structure is mainly carried out by adopting a mode that steel members and bolts are mutually combined.
At present, the glued wood structure node connection mode is to directly connect frame wood beams and wood columns by using steel members through bolt connection or using self-tapping screws, and the wallboard and the wood frame are not directly connected at the frame node connection part, so that the wallboard is only used as a filling member and cannot be effectively connected with the whole frame to form a whole body so as to provide more lateral rigidity for the structure.
In engineering, the construction process of the glued wood frame and the wallboard is usually carried out separately, namely, the assembly of the frame wood beam and the wood column is carried out firstly, then the assembly of the wallboard is carried out, the assembly process is complicated, the labor cost is increased due to time consumption, and even the dislocation of connecting holes is caused by the processing errors of the earlier-stage components, the wallboard needs to be returned to a factory for reprocessing, and the like, so that the assembly integration degree of the wood structure is too low.
Most traditional connecting pieces of glued wood structures are only composed of transverse steel plates or transverse steel plates and end plates, and in experimental research and engineering application, wood frames are mainly represented by beam end along-grain splitting damage, and steel connecting pieces are mainly represented by tearing damage of narrow-edge welding seams of the transverse steel plates and the end plates. A few traditional connecting pieces are provided with longitudinal steel plates, and researches show that the longitudinal steel plates can effectively prevent the longitudinal splitting damage of the wood at the beam end and the tearing damage of the narrow-edge welding seams of the transverse steel plates and the end plates. However, the longitudinal steel plate is easy to bend due to the fact that only the connecting piece of the longitudinal steel plate is arranged, so that the effect of limiting the wood downstream splitting damage of the beam end is not obvious.
In order to solve the problems, the assembly connecting component based on node connection is necessary to realize the integrated assembly connection of the wood frame beam column and the wallboard and the integral hoisting construction, and meanwhile, the integral performance of the wood structure is enhanced, so that the glued wood frame-wallboard structure achieves better anti-seismic performance, and the splitting damage of the beam end is effectively limited.
