Construction method of upturned beam foundation bottom plate and overhead plate

Abstract

The invention discloses a construction method of an upturned beam foundation bottom plate and overhead plate. The construction method comprises the following two steps that an overhead plate reservedsteel bar is arranged, a foundation beam steel bar is bound, a foundation bottom plate steel bar is bound, the overhead plate reserved steel bar is mounted, a beam side template is mounted, concrete is cast, the beam side template is removed, the overhead plate reserved steel bar is protected, and superstructure construction is conducted; and overhead plate construction is conducted, bottom layertop plate support is removed, the overhead plate reserved steel bar is cleaned, a sleeper wall is embedded steel bars, the sleeper wall and the overhead plate reserved steel bar are supported and arranged, an overhead plate reserved steel bar is bound and welded, inspection and acceptance are conducted, the concrete is cast, maintenance is conducted, and a surface layer is decorated. According tothe construction method, construction is convenient, stress is clear, safety of the structure is effectively ensured, the construction period can be effectively saved, stress is concise, the structureis safe, the problem of supporting the template when the foundation bottom plate and the overhead plate are cast together can be solved, safety of foundation affected due to the fact that construction joints are arranged on a foundation beam when construction is carried out in a conventional manner is avoided, and the problem that the construction method of a postposition prefabricated plate cannot solve the plate end cannot bear bending moment is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for an overhead slab of an upturned beam type foundation floor. Background technique [0002] With the growth of the country's economic strength and the acceleration of urbanization, the construction scale of individual projects continues to increase, and the land resources in large cities represented by Beijing, Shanghai, and Guangzhou are becoming increasingly scarce. Many buildings adopt main buildings and group buildings, or more The foundation of this building is an integral raft foundation, and the basement is equipped with multiple layers to effectively use the underground space. Due to the different loads of the superstructure, different parts of the overall foundation will be subjected to different forces, which may cause uneven settlement of the foundation and affect structural safety. For this reason, different designers adopt diffe...

Problems solved by technology

Now it is necessary to solve the problem of formwork support when the base slab and the overhead slab are poured together, avoid setting construction joints on the foundation beam during construction according to the conventional method and affect the foundation safety, and solve the problem that the slab end cannot bear the bending moment that cannot be solved by the post-installed prefabricated slab construction method The problem
