Steel pipe truss prestressed concrete laminated slab

Abstract

The invention discloses a steel pipe truss prestressed concrete laminated slab which comprises a reinforced concrete bottom plate and a steel pipe truss; a plurality of longitudinal prestressed steel bars are distributed in the reinforced concrete bottom plate; the steel pipe truss comprises a steel pipe and wavy steel bars welded to the two sides of the steel pipe; a wave trough section or / and a web member lower section of each wave steel bar is / are transversely bent to form a bent V-shaped bearing force transmission component; the wave trough section or / and the transverse lower section of a transverse bent web member is / are transversely embedded into the reinforced concrete bottom plate; the vertical lower section of the web member is embedded into the concrete bottom plate; longitudinal prestressed steel bars are arranged on the bent V-shaped bearing force transmission component; and the longitudinal prestressed steel bars and the bent V-shaped bearing force transmission component are glued into a whole by concrete. The structure strength is guaranteed, and meanwhile the characteristics of being convenient for industrial, standardized and mechanical production and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of lightweight building materials, in particular to steel pipe truss prestressed concrete laminated panels. Background technique [0002] In the existing technical field of lightweight building materials, concrete truss laminated slabs are more and more widely used in the construction industry, because concrete truss laminated slabs can reduce the number of construction formwork and scaffolding in the construction process, improve construction efficiency, and then reduce construction costs. . The existing concrete truss laminated slab is mainly composed of a base plate and a truss, and the concrete truss laminated slab integrated with the steel pipe truss is poured through the base plate. The internal structural strength of the existing concrete truss laminated slab is not guaranteed, the stability of the connection between the truss and the bottom plate is limited, and there is no restriction on the layout...

AI Technical Summary

Problems solved by technology

This kind of steel tube and steel bar composite truss is applied to the prestressed concrete laminated slab. When the components need to be installed, it is inconvenient to lay out the components. When the steel tube truss is manufactured, it is not easy to accurately position and weld, and it is not convenient for mechanized production.
