Self-heat-preservation double-formwork composite wall structure and composite wall comprising same

Abstract

The invention discloses a self-heat-preservation double-formwork composite wall structure and a composite wall comprising the same. The self-heat-preservation double-formwork composite wall structurecomprises an inner formwork, an outer formwork and a plurality of connecting ribs, wherein the outer formwork comprises a first surface protection layer, a first A-level fireproof heat preservation material layer and a first reinforcing net rack; the first surface protection layer is connected to the side, back on to the inner formwork, in the first A-level fireproof heat preservation material layer; the first reinforcing net rack is arranged in the first A-level fireproof heat preservation material layer; the plurality of connecting ribs are all positioned between the first A-level fireproofheat preservation material layer and the inner formwork; and the two ends of each connecting rib are connected to the inner formwork and the first reinforcing net rack correspondingly. The structuralstrength requirement and heat preservation performance of the self-heat-preservation double-formwork composite wall structure can be met; and meanwhile, the overall thickness is remarkably reduced, awall supporting system is omitted in the construction process, the prefabrication process and the construction process are further optimized, and effective application and popularization of the composite wall technology are better facilitated.

Description

technical field [0001] The invention relates to a self-insulating double-mode shell laminated wall structure and a laminated wall comprising the same. Background technique [0002] With the development of construction industrialization technology and the problems of labor shortage, low construction efficiency, and uneven construction quality are gradually exposed, prefabricated construction methods have gradually replaced the traditional ones due to their advantages of high construction efficiency, controllable quality, and labor-saving. Building construction method. The laminated wall is favored by the market because it does not require sleeves or grout anchor connections, has good integrity, and the two sides of the board are smooth and clean, and it combines the advantages of fast construction progress of the prefabricated structure and good integrity of the cast-in-place structure. [0003] There are currently two types of wall insulation systems made of laminated walls...

AI Technical Summary

Problems solved by technology

This method has complex construction procedures, long construction period, and many wet operations on site; the other is when the laminated wall components are prefabricated in the factory, one side of the laminated wall is used as an insulation layer (the insulation material is mostly XPS extruded board) or EPS polystyrene board) and the outer slab to replace the original concrete material, and then connect with the formwork on the other side through the steel truss; although this form basically realizes the integration of thermal insulation structure, but due to the factory prefabricated stacking Influenced by the structure of the composite wall components and the types of insulation materials, its overall thickness increases significantly, which has a great impact on the building volume ratio, the actual building area, and the cost.
