MF heat insulating and sound insulating fabricated concrete superposed sheet

Abstract

The invention discloses an MF heat insulating and sound insulating fabricated concrete superposed sheet. The MF heat insulating and sound insulating fabricated concrete superposed sheet comprises an MF heat insulating sheet, a prefabricated truss reinforced concrete superposed sheet and MF special accessories. The MF heat insulating sheet comprises multiple flat-put small sheets, the multiple small sheets are connected through H channel steel, the MF heat insulating sheet is arranged below the prefabricated truss reinforced concrete superposed sheet, a self-tapping anchor bolt vertically penetrates through the MF heat insulating sheet from the lower face to be connected with a bottom sheet of the prefabricated truss reinforced concrete superposed sheet, and the problems about heat insulating, sound insulating and fire proofing of the prefabricated superposed sheet are solved. The MF heat insulating sheet stretches out of the bottom of the prefabricated superposed sheet and then entersa post-cast strip, secondary formwork erecting of the post-cast strip is avoided, sheet gas slurry leakage is eliminated, the problem that the mounting efficiency is affected is avoided, meanwhile, the connecting strength and the energy-dissipating capacity after mounting is completed are combined with the advantages of super-high-performance materials and a prefabrication technology, the performance of the materials is exerted, and the influence of the manufacturing cost is lowered.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to an MF thermal insulation and sound insulation assembled concrete laminated board. Background technique [0002] With the rapid development of my country's construction industry, the country is actively promoting the transformation and upgrading of the construction industry, and prefabricated buildings have developed rapidly with their good economic, environmental and social benefits. The proportion of building energy consumption in total energy consumption has risen from 10% in 1978 to 38% at present, and it has become a consensus to vigorously develop energy-saving buildings. With the continuous improvement of building energy saving and environmental protection requirements, the thermal insulation technology of building structures is also increasingly strengthened, especially the floor thermal insulation and sound insulation technology has been developed rapid...

AI Technical Summary

Problems solved by technology

However, due to the secondary formwork used for the post-cast belt of the laminated slab, there are relatively few pouring operations on site

The initial cost of heat preservation, sound insulation and fire prevention in the floor is extremely high, and it is rarely used in prefabricated building structures
