Problems solved by technology

However, the reinforced concrete layer of the prefabricated concrete external wallboard and the insulation layer are independent, and the insulation layer mainly adopts polystyrene board (EPS), extruded plastic board (XPS) or rock wool to realize the insulation function, and ordinary concrete (dry density is about 2500kg / m 3 ), the mass of the overall wallboard is large, which is unfavorable to the force of the main structure, and requires high load-bearing capacity of the connecting parts with the main structure

Embodiment 1

[0023] Please refer to Figure 1 to Figure 3 This embodiment 1 provides a composite exterior wall panel 100, which includes a concrete wall 110 prepared by adding heat-insulating materials to Portland cement, and an exterior decorative layer 120 adhered to the inner and outer sides of the concrete wall 110, respectively. And the interior decoration layer 130, the interior of the concrete wall 110 is provided with a double-layer two-way steel mesh 140, and the double-layer two-way steel mesh 140 includes a first layer of steel mesh and a second layer of steel mesh arranged at intervals, and is connected to the The tie bars 150 between the first layer of reinforcement mesh and the second layer of reinforcement mesh. Wherein the concrete wall body 110 can be fixedly connected with the interior and exterior decoration layers in other ways.

[0024] The composite exterior wall panel 100 provided in this embodiment 1 is manufactured by industrial production, thus forming a light-we...

Embodiment 2

[0037] The difference between the second embodiment and the first embodiment is that the material of the decorative surface 121 of the outer decorative layer and the decorative surface 131 of the inner decorative layer can be fluorocarbon paint or paint layer, and the fluorocarbon paint can be used in harsh environments. No pulverization and no falling off, waterproof and dustproof, can guarantee decoration and adhesion for a long time, and has excellent flexibility, full color and good texture.

Abstract

The invention provides a composite external wall panel, which comprises a concrete wall body prepared by adding thermal insulation materials into silicate cement, wherein outer decorative layers and inner decorative layers are respectively arranged on the inner and outer sides of the concrete wall body; a double-layer bidirectional steel mesh is arranged inside the concrete wall body; the double-layer bidirectional steel mesh comprises a first layer of steel mesh and a second layer of steel mesh which are arranged at intervals; and Rachel steel bars connected between the first layer of steel mesh and the second layer of steel mesh. The composite exterior wall panel of the invention is suitable for exterior wall panels in fabricated buildings and has the performances of light weight, high strength, fire prevention, self-insulation, decoration, waterproof, sound insulation, frost resistance, convenient manufacture, environmental protection and the like.

Description

technical field [0001] The invention relates to the technical field of decorative building materials, in particular to a composite exterior wall panel. Background technique [0002] According to the national building standard design atlas 16J110-2 and 16G333 "Prefabricated Concrete Exterior Wall Hanging Panel (1)", the wall structure of the exterior wall hanging panel project can be divided into: sandwich insulation system, internal insulation system and external insulation system according to the type of insulation. The thermal insulation system is composed of a reinforced concrete layer and a thermal insulation layer through connectors. It has the functions of enclosure, fire protection, heat preservation, heat insulation, sound insulation, and decoration. Because of its high integration, mechanization, industrialization, and product quality It is easy to be effectively controlled, saves labor and material costs, and shortens the construction period, making it widely used ...
