Polyphenyl core panel composite heat insulation external wall panel

Abstract

The invention belongs to the technical field of building engineering and particularly relates to a polyphenyl core panel composite heat insulation external wall panel. The polyphenyl core panel composite heat insulation external wall panel is characterized in that the front side and the back side of a polyphenyl core panel in the length direction are respectively provided with linear longitudinal steel bar grooves, the polyphenyl core panel is provided with annular steel bar grooves in the width direction, linear steel bars and annular steel bars are arranged in the longitudinal steel bar grooves and the annular steel bar grooves, the linear steel bars and the annular steel bars form a steel bar mesh cage, the polyphenyl core panel is surrounded in the steel bar mesh cage, steel wire mesh sheets are arranged on the steel bar mesh cage, light-weight heat insulation mortar wraps the steel wire mesh sheets and the steel bar mesh cage to from a light-weight heat insulation mortar case layer, the polyphenyl core panel is arranged in the light-weight heat insulation mortar case layer, a connecting iron element is welded with the steel bar mesh cage, and the end part of the connecting iron element is exposed out or extends out of the light-weight heat insulation mortar case layer. The polyphenyl core panel composite heat insulation external wall panel has the advantages that the industrial production can be adopted, the panel case light-weight heat insulation mortar raw materials adopt the electronic metering and the mechanical grouting, the grouting pressure is monitored through a computer, the electronic temperature control is adopted, and the panel specification size and the thickness of each layer of the panel are enabled to be respectively in the control requirement range.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a polyphenylene core board composite thermal insulation outer wall panel which is used for structural engineering such as frames, bent frames, and shear walls, and has the functions of thermal insulation and enclosure structure. Background technique [0002] At present, in domestic industrial and civil construction projects, the outer protective walls of frames, bent frames, shear walls and other projects mainly use medium and small block walls, such as aerated concrete blocks or hollow brick block walls, etc., and the outside of the masonry Paste or spray organic insulation materials, such as polystyrene board insulation board, foam plastic and so on. The above-mentioned method has many processes, heavy engineering construction and management tasks, and is prone to problems such as hollowing, cracking, water seepage, and shedding, and has poor firep...

AI Technical Summary

Problems solved by technology

The above-mentioned method has many procedures, heavy engineering construction and management tasks, and is prone to problems such as hollowing, cracking, water seepage, and falling off, and has poor fireproof performance and great potential safety hazards.

In recent years, the practice of utilizing the thermal insulation performance of aerated concrete masonry has been introduced in China, that is, B05-grade aerated blocks are used for aerated concrete walls, no additional insulation materials are added, and low-density B03 and B04-grade aerated materials are used for beams and columns. Concrete is used as the insulation layer. This method undoubtedly makes the construction easier and has better fire resistance. However, due to the high production requirements, low output and high cost of the aerated blocks B03, B04, and B05, this product cannot be produced in many areas, resulting in It is difficult to implement this method of utilizing the thermal insulation performance of air-entrained concrete itself
