Floor structure formed by prefabricated trough plates and construction method

Abstract

The invention provides a floor structure formed by prefabricated trough plates and a construction method. The floor structure formed by the prefabricated trough plates comprises at least two prefabricated trough plates, longitudinal beams and lightweight filling layers, wherein the prefabricated trough plates are filled with the lightweight filing layers; the two ends of each prefabricated trough plate are erected on a building structure; every two adjacent prefabricated trough plates are arranged at intervals mutually to form a longitudinal beam rear pouring zone; the position of the longitudinal beam rear pouring zone is configured with longitudinal beam reinforcing bars in a through-long mode and filled with concrete to form the longitudinal beams; the prefabricated trough plates are reinforced concrete prefabricated trough type components comprising a base plate and two plate ribs and formed integrally; the plate ribs are arranged at intervals in parallel in the transverse direction of the base plate, and each plate rib is arranged in the longitudinal direction of the base plate in a through-long mode and connects plate blocks together; and plate rib preformed holes are formed in the side faces of the plate ribs in the longitudinal direction at intervals correspondingly. The floor structure formed by the prefabricated trough plates and the construction method solve the technical problems that by adopting a traditional method, constructed floor structures are high in weight, the construction process is complex and the durability is poor.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a floor structure made of prefabricated grooved plates and a construction method. Background technique [0002] As we all know, the floor member in the building is a special building structural member. It bears the upper load and transmits the load to the lower main structure. It is also a horizontal enclosure that separates the upper and lower spaces of the building. member; [0003] As a stressed structural component, the floor structure must have sufficient structural performance and durability, including strength, stiffness and service life; as an enclosure component, the floor structure must have sufficient enclosure performance, including building physics such as sound insulation and heat conduction. performance. [0004] At present, in my country, the vast majority of building floor components are ordinary cast-in-place concrete components (see the concrete structure s...
