Fabricated cast-in-place concrete sandwich insulation wall steel frame formwork system and connecting parts

Abstract

The invention provides a fabricated cast-in-place concrete sandwich insulation wall steel frame formwork system (for short, a system) and connecting parts. The system is mainly composed of a concrete protection layer, an insulation layer, a truss, horizontal steel bars and non-dismantling cement boards or formworks. The insulation layer is formed by assembling insulation modules (boards) in a tongue-and-groove insertion mode, each insulation module (board) is fixed to one side of the truss through the connecting parts, and the concrete protection layer is laid outside the insulation layer. Each connecting part comprises a connection tap bolt, a positioning disc and a wire mesh fixing head, wherein a limiting protrusion is arranged on the outer side of the positioning disc. The system can be horizontally assembled on the ground, poured to be molded and integrally hoisted, the truss can be one part of steel bars of a bearing wall, after bearing wall concrete is poured, the system and the concrete structure are integrated, and the concrete composite wall with a sandwich insulation layer is formed. By means of the fabricated cast-in-place concrete sandwich insulation wall steel frame formwork system and the connecting parts, construction procedures of the sandwich insulation composite wall of an energy-saving building can be made simple, the easy construction property is high, the overall construction speed and labor efficiency of the energy-saving building can be greatly improved, construction safety risks are reduced, construction precision is effectively improved, and engineering quality is guaranteed; and meanwhile, technical support is provided for building industrialization.

Description

technical field [0001] The present invention relates to building materials, in particular to a complete set of technology combining thermal insulation materials, wall structures and construction techniques for building energy-saving buildings. Background technique [0002] The thermal insulation module (board) material has been widely used in the insulation of building walls. The usual way of use is to paste the thermal insulation module (board) on the surface of the wall that has been constructed to form an insulation layer, or to use the thermal insulation module (board) ) to form a template, and then pour concrete, so that the thermal insulation module (board) and the concrete are integrated to form a thermal insulation wall or a sandwich thermal insulation wall. However, whether it is the former or the latter, the thermal insulation modules (boards) must be spliced ​​on site, and the on-site construction material loss is large, and the ease of construction is poor, resul...

Problems solved by technology

However, whether it is the former or the latter, the thermal insulation modules (boards) must be spliced ​​on site, and the on-site construction material loss is large, and the ease of construction is poor, resulting in low overall construction speed of energy-saving buildings, long construction period, and high construction costs.

[0003] During the 13th Five-Year Plan period, the country vigorously promoted prefabricated buildings, but there were very few prefabricated component production bases supplying prefabricated buildings. Compared with developed countries, the technical strength and level were still in the initial stage, and they were far from being able to fully enter the construction market. needs
