Box-type modular building corner splicing node structure

Abstract

The invention provides a joint joint structure at the corner of a box-type modular building. The box-type module is composed of four top beams, four bottom beams, four square steel pipe columns and eight corner reinforcements; The web plate arranged in the axial direction of the column and the flanges vertically connected to both sides of the web plate; the two beams intersecting at the same corner are connected by a corner reinforcement, which includes two corner plates and two vertical plates And a steel pipe section with the same height as the crossbeam; the vertical plate of the adjacent corner reinforcement between the upper and lower connected box modules is connected with a joint connecting plate by common bolts, and the upper and lower corners of the adjacent corner reinforcement between the upper and lower connected box modules Plate bolt connection; the vertical plates of the adjacent corner reinforcements between the left and right connected box modules are jointly bolted to a node connection plate. The invention has multiple advantages such as clear force transmission, reasonable structure, simple construction, easy assembly and disassembly, etc., and meets the requirements for prefabricated assembly and installation and multi-storey building load-bearing performance.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building steel structure construction, and in particular relates to a spliced ​​node structure at the corner of a box-type modular building. Background technique [0002] The construction industry is an important material production sector of the national economy, and has a close relationship with the development of the entire country's economy and the improvement of people's lives. The traditional construction method is mainly based on on-site manual wet work, which not only has low production efficiency, long construction period, high energy consumption, and great impact on the environment, but also it is difficult to guarantee the quality and performance of the building, and it is difficult to realize the life cycle. The pace of rapid economic development cannot meet the requirements of sustainable development. Therefore, one direction for the further development of the construction indu...

AI Technical Summary

Problems solved by technology

Among them, the welded joint saves more materials under the premise of ensuring safety, but the on-site construction workload is heavy, and it is inconvenient to dismantle, which does not meet the development needs of industrialized buildings

Compared with welding, the on-site splicing operation of corner piece connection, pad piece connection and corner post connection is slightly simpler, but the bearing capacity is small, so it can only be used in low-rise modular buildings
