Self-supporting thermal insulation hollow floor slab and construction method thereof

Abstract

The invention discloses a self-supporting heat insulation hollow floor and a construction method thereof. The self-supporting heat insulation hollow floor comprises a plurality of frameworks consisting of bottom plates and multiple steel bar trusses erected above the bottom plates and connected with the bottom plates, the opposite ends of the bottom plates of the two adjacent frameworks are connected, and concrete is poured on the steel bar trusses. The self-supporting heat insulation hollow floor is characterized in that: the bottom plate comprises a steel wire gauze and heat insulation plates and / or sound insulation plates positioned on the steel wire gauze, and the bottoms of the steel bar trusses are connected with the bottom plates through a plurality of connectors. The self-supporting heat insulation hollow floor has the function of heat insulation or sound insulation; and meanwhile, the consumption of steel is reduced, so that the production cost is reduced. The invention has the advantages that: the construction method is simple in operation and is easy to learn and use.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a self-supporting thermal insulation hollow floor slab and a construction method for the self-supporting thermal insulation hollow floor slab. Background technique [0002] The reinforced truss floor deck is to weld the upper and lower longitudinal steel bars (that is, the upper and lower chords) with the bent and formed small-diameter steel bars (that is, the abdominal bars) to form a small truss that has a certain rigidity and can bear the load. The trusses are welded with profiled steel plates and then cast in-situ concrete. Reinforced truss floor deck has the advantages of high overall rigidity and good seismic performance, and because of its short construction period and easy control of construction quality, it has been widely used in many projects at home and abroad in recent years. [0003] The patent number is ZL200520031277.7, and the Chinese patent titled "reinf...

AI Technical Summary

Problems solved by technology

[0005] 1. The bottom plate only serves as the formwork during the construction process, and does not play any role under normal use conditions, which is not conducive to decoration and increases the project cost

[0006] 2. The bottom plate of the reinforced truss floor deck is generally made of steel plate, which increases the amount of steel used in the building structure, which is not conducive to environmental protection, energy saving and emission reduction

[0007] 3. During use, the maintenance of the bottom plate increases the cost of use and affects the durability of the structure

[0008] Due to the above shortcomings, the steel truss floor deck is currently only used in public and large commercial buildings, which limits its popularization and application in a large number of civil buildings
