Description

Technical Field

[0001] The invention mainly relates to drilling construction technology, and in particular to an assembled building. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., and are representatives of modern industrialized production methods because they use standardized design, factory production, assembly construction, information management, and intelligent applications.

[0003] The existing prefabricated concrete structures all first lay the foundation, and then pre-embed the anchor bolts on the foundation to achieve the rapid assembly of the wall panels and the foundation. Similarly, the connecting bolts are pre-embedded on the wall panels and beams to achieve the connection of the wall panels, floor slabs and beams on different floors. Since it is impossible to achieve a very high flatness when excavating the foundation, and when placing the anchor bolts, it is difficult to ensure the verticality, height, spacing and horizontal deflection of all the anchor bolts of the entire building, so a lot of manpower is needed on site for manual observation and adjustment of the anchor bolts at each node position. In addition, since the area involved in the arrangement of the anchor bolts on site is very large, even if a lot of manpower and material resources are spent, it is impossible to ensure the consistency of the verticality, height, spacing and horizontal deflection of all the anchor bolts.
