Connection structure of column-supported integrated building modules

Abstract

The invention discloses a connection structure of a column-supported integrated building module, which includes a steel pipe built-in butt connector for connecting the upper corner column and the lower corner column, and is arranged on the upper long side beam of the lower integrated building module and the upper integrated building module. For the shear connector between the lower long side beams, at least one horizontal connecting steel plate is respectively fixed between two horizontally adjacent long side beams or short side beams to connect two horizontally adjacent integrated building modules to prevent the modules from The horizontal separation between the upper and lower integrated building modules is provided with vertical tie rods between the upper and lower corresponding horizontal connecting steel plates. The present invention provides corresponding force transmission paths for each possible node force transmission mode, and designs corresponding force transmission components, thereby fully considering the complex node load conditions of the module under various working conditions, which are some Key nodal force forms provide multiple force transfer paths and structural measures.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a connection structure of column-supported integrated building modules Background technique [0002] Integrated modular building is a new type of construction mode. The building modules with a high degree of completion complete more than 90% of the construction in the factory environment, and then transported to the construction site with large-scale transportation equipment for assembly. The assembly process is mainly through the on-site structural connection of the key module nodes to form the overall rigidity of the structure, followed by matching the joints between the building modules to ensure its safety, waterproof, sound insulation and anti-corrosion and other architectural requirements. Because of the limitations of transportation, lifting and installation, integrated modules are often produced, transported and installed in the form of cuboid modules. The longest ...

Problems solved by technology

[0004] 2. Modular buildings require high manufacturing and installation precision, small fault-tolerant space for on-site construction, high construction difficulty, and many restrictions on construction plans, resulting in low shear resistance between upper and lower modules of modular buildings and insufficient connection strength, which is not suitable for high-rise buildings. Suitable for areas with high seismic requirements;

[0005] 3. Column-supported modular buildings mostly adopt a double-beam structure. The floor beams of the upper module are separated from the ceiling beams of the lower module. Large, so the overall structural efficiency is low, and the steel consumption is large, and at the same time, the building structure is high, so it occupies a large indoor space and increases the construction cost;
