Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of modular building, and in particular to a concrete wallboard structure modular residence system. BACKGROUND

[0002] Modular building is a construction method that divides a building into modular units, which complete the construction process of structure, decoration, water and electricity, equipment pipeline, etc. in the factory, and then are quickly assembled into a whole building on site through reliable connection technology. It has high engineering and standardization, and has the advantages of reliable quality, high efficiency and environmental friendliness, and is gradually used more and more widely.

[0003] Modular building design is quite different from traditional design, and requires intensive pre-project planning and work. The division of modules and the connection method are key factors affecting the cost and reliability of the whole modular building. In modular design, unlike ordinary fabricated buildings, it is necessary to integrate structure, electromechanical and decoration into one module. The size and shape of the module are limited by the use function, production, transportation and on-site installation conditions, and need to be determined comprehensively. In addition, the module requires a certain standardization to facilitate mass production and assembly.

[0004] The connection method of modular building is the key link to ensure the integrity of the structure, and the connection node should be reliable in force transmission, reasonable in structure and convenient in construction. According to whether secondary pouring is needed on site, the node connection method is divided into two types of wet connection and dry connection. Wet connection is a method of connecting components by reserving steel bars and pouring concrete or grouting on site. It has been proved in practice that wet connection can provide good overall performance, comparable to cast-in-place structure, but the connection method has the disadvantages of complex construction process, difficult quality control and long construction period. Dry connection mainly uses welding or bolt connection technology and does not need secondary pouring on site. Dry connection is fast in construction, convenient in maintenance and conducive to material recycling, fully embodying the trend of building industrialization, so modern modular buildings tend to use dry connection.

[0005] However, the integration level of modular building of concrete structure in China is still low, and most modular buildings still use ordinary fabricated methods to transport separate components (such as beams, columns, walls, stairs, etc.) pre-fabricated in the factory to the site for assembly, and then perform subsequent electromechanical and decoration construction on the basis of on-site assembled buildings, which weakens the industrialization advantage of modular building. Limited by the maturity of technology, dry connection is rarely used in China. The scope and performance of dry connection of prefabricated components are limited. For example, there is a connection method for prefabricated floor slabs and floor slabs, but it does not achieve equal strength connection, thereby limiting the development and application of integrated modular building technology.
