Connection node and construction method of wall and floor grille of prefabricated wood structure house

Abstract

The invention relates to an assembly type wood structure house wall and floor grating connecting joint and a construction method. The assembly type wood structure house wall and floor grating connecting joint comprises a wall, a grating floor, a steel base plate and a connecting bolt. The wall is a wood member, the middle of the wall is provided with a wood framework, and the outer side of the wood framework is connected with a wall outside OSB. The wall outside OSB is locked to the wood framework through hobnails. The inner side of the wood framework is connected with a wall inside OSB. The wall inside OSB is locked to the inner side of the wood framework through hobnails. The wall comprises an upper wall layer and a lower wall layer. The grating floor is a wood member, the middle of the grating floor is provided with a wood keel, and the joint of the wood keel and the inner wall is provided with an inner end sealing plate and an outer end sealing plate. The upper wall layer is connected with the grating floor through the connecting bolt which penetrates through the steel base plate, the inner end sealing plate and the outer end sealing plate. The grating floor is connected with the lower wall layer through the connecting bolt.

Description

Technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a connection node between a fabricated wooden structure house wall and a floor grille and a construction method. Background technique [0002] The development of prefabricated buildings has been included in the government work report. The development of prefabricated wood-structured houses can not only meet the needs of building "energy saving and resource saving", it is of great environmental protection significance, and it is in line with the basic national policy of social development. [0003] The development of prefabricated light wood structures to adapt to buildings is similar to steel structures. The prefabricated light wood structure nodes are the key link of the entire structure system, which plays an important role in the bearing capacity, stiffness and ductility of the entire structure, which is different from traditional ancient buildings. In the for...

AI Technical Summary

Problems solved by technology

According to the analysis of a large number of engineering examples, it is found that most of the damage of wood structures occurs at the joints, and the main reason for the damage is due to the insufficient bearing capacity, stiffness or ductility of the joints. Taking the commonly used connectors as an example, usually the wooden grid floor The connection with the wall is mainly through connectors. The vertical force of the wooden grille floor is mainly connected by the shear force of the nails on the connectors. The connection strength is not easy to guarantee, and the construction is more cumbersome and the construction speed is slow.
