Composite floor slab based on polyphenyl granule fiber concrete sandwich insulation and construction method

Abstract

A composite floor slab based on polyphenyl granule fiber concrete sandwich insulation comprises a prefabricated bottom plate concrete layer, a polyphenyl granule fiber concrete prefabricated bottom plate insulation layer is arranged on the prefabricated bottom plate concrete layer, and a post-poured layer is arranged on the polyphenyl granule fiber concrete prefabricated bottom plate insulation layer. The invention further provides a construction method for the composite floor slab. The polyphenyl granule fiber concrete sandwich insulation layer is poured on the basis of a common steel bar truss composite floor slab, and the novel sandwich insulation composite floor slab is formed by combining the prefabricated bottom plate concrete layer, the polyphenyl granule fiber concrete insulation layer and the on-site post-poured layer; load bearing and heat insulation of the floor slab are integrated, later insulation treatment of a roof panel is omitted, and field operations are reduced; and the mode of combining a steel bar truss and a rough surface is further adopted, the steel bar truss penetrates through the three layers of the whole composite floor slab to tightly combine the three layers of the whole composite floor slab, and thus the bearing capacity, shear capacity and integrity of the composite insulation floor slab are improved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a laminated floor slab based on polyphenylene particle fiber concrete sandwich insulation and a construction method. Background technique [0002] The "Thirteenth Five-Year Plan" outline proposes: develop applicable, economical, green and beautiful buildings, improve construction technology, safety standards and engineering quality, and promote prefabricated buildings and steel structure buildings. Prefabricated buildings have standardization of design, industrialization of components, and mechanization of construction, which greatly reduce the use of on-site operations and labor. Green, environmental protection, and energy saving are the development direction of my country's future buildings. Concrete laminated floor slabs have the advantages of industrialization of components, production without seasonal restrictions, greatly shortened cycle, and saving a lot o...

AI Technical Summary

Problems solved by technology

Although the laminated floor slab has fulfilled the basic requirements for the development of prefabricated buildings, there are still some problems: the laminated floor slab still needs to be poured concrete on site; the roof slab still needs to be heat-insulated and waterproofed in the later stage.
