CN2675760Y - Assembled external heat-insulation plate for external wall - Google Patents

Abstract

The utility model relates to an assembled external heat-insulation plate for an external wall, which is characterized in that: the plate is formed from inside to outside by an inner surface decorative layer, a vibrating-free foot wall layer made of haydite and reinforced concrete, an adhesive layer of polymer mortar, a heat-insulating layer of polyphenyl plate, an adhesive layer of polymer mortar, and a coating layer. The plate is also pre-buried with a crampon and connecting parts which are adaptive to steel construction and frame construction. A sealing strip is provided at the seam between the two plates. The utility model is suitable for mass production in the factory, transportation and on site hoisting, and is free from seasonal influence in operation. And in addition, the utility model has the advantages of heat insulation, sound insulation, high durability, good weatherability, non-scale, environmental protection, and low cost, overcoming the cold bridge phenomenon.

Description

Prefabricated external wall insulation wall panels

1. Technical field

The utility model relates to a prefabricated component of building materials, in particular to an exterior thermal insulation wall panel for an exterior wall matched with a steel structure and a frame structure in an assembled building structure system.

2. Background technology

Prefabricated buildings are the mainstream of the development of construction technology in the world construction industry in the 21st century. Prefabricated buildings mainly adopt new multifunctional building material components that are prefabricated, factory-produced, and can be flexibly assembled on the construction site, and are assembled with steel beams and column frames to form exterior walls, roofs, and interior walls. the whole building. Prefabricated buildings have the advantages of light weight, short construction period, high degree of industrialization, and good seismic performance. At present, prefabricated buildings are developing in the direction of fully assembled, multi-storey or high-rise building structures. my country's building systems are mostly brick-concrete structures, frames, and shear wall structures, and steel structures are also beginning to develop gradually. In the entire prefabricated building structure system, the exterior wall panel is an important link. Due to the improvement of building energy-saving technology requirements, the technology of prefabricated building systems is not very mature. At present, the durability, weather resistance, scope of application and construction quality of wall panels have certain defects. Some external wall panels have cracks in the wall within one year. , paint peeling, cracking, peeling, moldy houses, condensation and other phenomena. In addition, some building adhesives for exterior wall panels do not meet environmental protection requirements and are harmful to human health.

3. Contents of the invention

The purpose of this utility model is to provide a prefabricated exterior thermal insulation wall panel, which is suitable for prefabricated building systems, can be produced in a factory, assembled on site, and has the functions of heat preservation and sound insulation. The wall has good durability and weather resistance. No cracks, good wall surface decoration, no peeling, cracking, peeling, can overcome the cold bridge phenomenon, environmental protection, and economical cost.

The purpose of this utility model is achieved in that:

A prefabricated external thermal insulation wall panel, which is characterized in that: the wall panel consists of an inner surface decoration layer, a vibration-free ceramsite reinforced concrete base wall layer, a polymer mortar adhesive layer, and a polystyrene board from the inside to the outside. Insulation layer, polymer mortar bonding layer and paint layer, the wall panel also pre-embeds lifting hooks, connecting pieces matching the steel structure and frame structure, and sealant is installed at the seam between the two wall panels strip.

In the above solution, the wall panel may be provided with mounting holes for doors and windows.

The utility model has the advantages that it is suitable for mass production in factories, can be transported and hoisted on site, the construction is not affected by the seasons, and has the functions of heat preservation and sound insulation, the wall has good durability and weather resistance, and the wall surface is well decorated. No peeling, cracking, and peeling, can overcome the cold bridge phenomenon, environmental protection, and economical cost.
