Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to a modular building composite beam structure. Background Art

[0002] Modular buildings are conducive to comprehensively improving the quality of buildings, reducing environmental pollution and ecological damage, and conforming to the national green development concept and the policy orientation of building a resource-saving society. With the rapid development of prefabricated building technology, modular buildings are widely used in building scenarios such as office buildings, residential buildings, hospitals, schools, etc. due to their advantages of factory prefabrication and rapid on-site installation. However, there are still many technical challenges in the structural adaptability, connection node design, and economic performance of existing modular buildings.

[0003] On the one hand, the integrity of ordinary modular building structures is poor, especially their applicability in high-rise buildings is limited. Since the modular floor slabs are prefabricated in sections and the boxes are independent of each other, and only connected by steel plates at the nodes, it is impossible to effectively form an overall structural system, and the overall stiffness is insufficient, making it difficult to meet the strict requirements of high-rise buildings for earthquake resistance, wind resistance, and bearing capacity. Therefore, strengthening measures such as cast-in-place roofing, rigid connection nodes, setting internal supports, and constructing lateral force resistance systems need to be taken, but these measures significantly increase the construction difficulty and cost, affecting their economy.

[0004] On the other hand, as a key technology of modular building structures, the rationality of the connection node design directly relates to the overall safety of the building, the convenience of construction, and the economic cost. At present, the connection nodes of different projects are often individually designed due to differences in building functions, construction environments, etc., and have not been standardized and generalized, which is not conducive to industrial production and popularization and application.

[0005] In addition, there is a problem of large steel consumption in the existing modular structures in terms of node construction and system configuration. Especially in buildings with high performance requirements, such as hospitals, schools, and high-rise buildings, in order to achieve comfort and safety, energy dissipation and shock absorption components often need to be introduced, resulting in an increase in cost and a more complex design. In terms of structural performance, it is difficult to achieve the cooperative work of beams and the continuity of floor slabs between the upper bottom beam and the lower top beam of the module, as well as between the left and right bottom beams, resulting in low floor comfort. To improve the floor comfort, additional secondary beams usually need to be added or the cross-section of the main beam needs to be increased, further affecting the overall design and economy.
