Abstract
Description
Technical Field
[0001] The invention relates to the technical field of modular buildings, and in particular to a construction method of a high-rise concrete module and a high-rise concrete module connection structure. Background Art
[0002] With the rapid development of building industrialization, modular buildings have attracted widespread attention due to their advantages such as high construction efficiency, high degree of standardization, labor saving, low carbon and environmental protection, safety and reliability. Modular buildings decompose buildings into several three-dimensional box modules, prefabricate them in factories, complete integrated decoration, and transport them to the construction site for rapid assembly, thus completing the entire construction process. This construction method not only improves the quality of prefabricated modules, but also minimizes on-site operations, improves construction efficiency, saves labor, and reduces environmental impact. High-rise modular buildings usually use two types of modular units: concrete modules or steel structure modules. Steel structure modules are easy to process, install and connect, but have the disadvantages of poor corrosion resistance, poor sound insulation and poor living comfort. Concrete modules have good fire resistance, heat insulation and sound insulation, and concrete modular buildings have high living comfort.
[0003] However, the connection technology between concrete modules faces a series of challenges. The traditional vertical connection technology of prefabricated concrete components requires a lateral working surface, while the installed concrete modules will limit the outer working surface of the adjacent modules to be installed, and the interior decoration of the concrete modules has been completed, so construction work is not allowed. Therefore, the traditional prefabricated vertical connection technology is not suitable for concrete modular buildings. At present, the concrete modular structural systems that have been actually applied mainly include the Singapore PPVC system and the China Hailong MIC system. The structural design of Singapore does not take earthquake effects into consideration. According to the requirements of my country's seismic code, the connection structure of the PPVC system is difficult to meet and is not suitable for direct application in my country's high-rise residential buildings. The modules of the MIC system use thin shell plates as the module formwork. The formwork is only used as a casting template and does not participate in the structural force, resulting in a reduction in the usable space of the building and a large amount of on-site casting work.
[0004] At present, there is a Chinese patent application publication number CN117988562A that discloses a new method for constructing a high-rise concrete modular building, which is to construct a modular frame by layers with multiple module units, install steel cages in the gaps between adjacent module units, bury steel bars in the L-shaped two-way connecting grooves connected in adjacent module units, and pour concrete by layers to form a whole. At the same time, vertical prestressed steel bars are set in the post-cast layer of the exterior wall to improve the building rigidity and enhance the crack resistance of the exterior wall. After implementing the above steps layer by layer, the entire modular frame is integrated into an integrated modular building. However, this patent requires the setting of numerous L-shaped two-way connecting grooves, in which steel bars are buried, which reduces the connection efficiency and overall performance between high-rise concrete modules.

The vertical dowel bars are simultaneously inserted through the pull rings reserved for the adjacent modules, and the pull rings of the adjacent modules are cross-connected; 3) Use foam glue to seal the side of the joints of the grouting parts between adjacent high-rise concrete modules, and use square wood to seal the side of the staggered connection structure. Pour the grouting material into the wall shell joints of adjacent high-rise concrete modules from the top of the vertical keyway to fill the staggered connection structure and vertical keyway between adjacent modules densely; 4) Arrange the lap reinforcement horizontally at the top of the wall shell joint, tie and connect the lap reinforcement with the truss reinforcement of the adjacent module, then tie the top reinforcement of the superimposed layer, and finally pour the superimposed layer concrete to connect the concrete modules on the same layer into a whole.
9. The construction method of the high-rise concrete module connection structure according to claim 8, characterized in that: The laminated layer includes lap steel bars, top bars and laminated layer concrete placed between adjacent modules. The top bars and lap steel bars are arranged perpendicular to the length direction of the joints between the modules. The lap steel bars are tied and connected to the truss bars of the top plate. The diameter of the lap steel bars should not be less than 8mm, the spacing should not be greater than 300mm, and the length of the lap steel bars anchored in the module laminated layer should not be less than 500mm.
10. The construction method of the high-rise concrete module connection structure according to claim 8, characterized in that: The grouting material is made of ultra-high-strength fiber concrete, whose cubic compression resistance is 80MPa-120MPa, expansion is 600mm-800mm, and slump is 100mm-150mm.
