Combined type relief component cast-in-situ hollow building roof and construction method thereof

Abstract

The invention belongs to the field of general building construction, in particular to a combination-typed off-loading component cast-in-situ hollow floor and a construction method. The invention adopts a technical proposal that the invention comprises off-loading components which are fixed between an upper layer reinforcement and a lower layer reinforcement by a fixed connecting part; the concrete is filled in the gaps between the off-loading component and the reinforcement in the whole floor and between the off-loading components; the off-loading component comprises at least two cylindrical or box-shaped or spherical off-loading cells; the off-loading components are intermittently or compactly arranged; the off-loading components with different shapes are combined and applied; the type and form of the off-loading components are smartly arranged according to the requirement, thus having the advantages of good porosity, good quality, light self-weight and optimum section.

Description

technical field [0001] The invention belongs to the field of general building construction, and in particular relates to a combined cast-in-place hollow floor of a load-reducing component and a construction method thereof. Background technique [0002] Due to the characteristics of the cast-in-place hollow-core slab, it can reduce the weight of the structure, save materials, optimize the cross-section, improve the thermal insulation performance, sound insulation performance and bearing capacity of the building, etc., and it has been widely promoted and used in the current construction field. The application of load-bearing components in hollow-core floors is also extensive. At present, cylindrical load-relief components are the most widely used, but the two-way stress of cylindrical components is not good, it is not suitable for floors with relatively high force requirements, and cannot meet engineering requirements, while box-shaped load-relief components have a relatively ...

AI Technical Summary

Problems solved by technology

At present, cylindrical load-relief components are the most widely used, but the two-way stress of cylindrical components is not good, it is not suitable for floors with relatively high force requirements, and cannot meet engineering requirements, while box-shaped load-relief components have a relatively low porosity Low, the amount of steel and concrete is high, the cost is high, and due to the constraints of engineering requirements such as the shape of the floor, the shape of the load-relief member, and the force requirements, a certain gap must be left when the load-relief member is placed. It is used to meet the needs of pouring concrete, and the corners of the floor and other parts where it is not easy to place the mandrel need to be filled with concrete, and the shape of the mandrel to be filled is single, and the bearing capacity of the floor is uneven, so the hollow floor The porosity is relatively low, the amount of concrete is large, the floor is heavy, and the overall cost of the project is high
