Description
Technical Field
The invention relates to the field of constructional engineering, in particular to an assembled building floor slab and a construction method.
Background
The assembly type building structure is a building structure which is designed and built in a field assembly mode by mainly taking prefabricated components produced in factories, and is one of important directions for building structure development in China. Compared with the traditional building structure, the assembly type building structure can reduce building garbage, and better meets the requirements of energy conservation, material conservation, water conservation, environmental protection, sustainable development and the like of green construction; the components can be produced in a factory, the production cost is reduced, and the working efficiency is improved. The stress performance of the fabricated building structure is mainly influenced by the force transmission reliability of the prefabricated part connecting node, and the stress of the column-column connection, the beam-slab-column connection and the beam-beam connecting node is very complex and is particularly prominent under the action of an earthquake. Meanwhile, the connection mode of the assembly type components also influences the structure transmission and the engineering installation construction.
At present, beams and columns of an assembly type building structure generally need to be prefabricated independently, and floor slabs mainly adopt the forms of prefabricated floor slabs, cast-in-place or laminated slabs. When in site construction, the beam and the column are assembled in a bolt or welding mode, and the floor slab is installed after the beam and the column are assembled. The modular construction in this form presents the following disadvantages: the cast-in-place concrete floor slab has low construction speed and large template consumption, and is easy to cause environmental pollution; the traditional precast concrete floor has poor integral performance; although the overall performance of the laminated slab is superior to that of the traditional precast concrete floor slab, the construction efficiency is affected due to on-site wet operation; the structure nodes are more, the site operation is complex, and the site welding construction quality of the node area is difficult to guarantee.
Moreover, the design and production processing of the prior domestic prefabricated concrete building are disjointed under most conditions. Most prefabricated part processing factories still adopt the traditional processing mode, the prefabricated part production generates a part processing drawing according to a design institute drawing, manual sample turning is carried out, a production floor slab is manufactured and then transported to a field for assembly, the assembly process is mastered by field workers, in the traditional production mode, information formed in the design stage is not completely and effectively transmitted to the production construction stage, the data reuse rate is very low, time and labor are wasted, and the experience of deepening processing personnel seriously influences the processing efficiency and the processing error rate; moreover, the designer does not know the production and assembly process, and the owner only occasionally visits the site and can only know the specific conditions of the production and assembly by site workers, so that the blind area for knowing the conditions of the production and assembly exists for the owner and the designer.
