Rigid-bone homogeneous external wall panel and manufacturing process thereof

Abstract

The invention discloses a rigid-bone homogeneous external wall panel and a manufacturing process thereof. The rigid-bone homogeneous external wall panel specifically comprises a bottom protection layer, a middle rigid frame layer and a top layer, wherein the middle rigid frame layer comprises a rigid framework formed by connecting and combining C-shaped fins, straight-plate-shaped fins and pulling and pressing rods, a plurality of pouring cavities are formed in the rigid framework, and lightweight concrete is poured in the pouring cavities; and the C-shaped fins are arranged in a longitudinal and transverse queue mode, a plurality of grids are defined by the C-shaped fins, through holes are formed in the C-shaped fins, pulling and pressing rods are arranged in the through holes in a penetrating mode, the pulling and pressing rods are arranged in a longitudinal and transverse queue mode, and the C-shaped fins are connected and fixed through the pulling and pressing rods. According to the rigid-bone homogeneous external wall panel and the manufacturing process thereof, various defects of an existing composite external wall can be overcome, and the manufactured external wall panel has the performance of being multi-dimensionally high in rigidity, small in deformation amount and good in heat preservation performance.

Description

technical field [0001] The invention relates to a rigid bone homogeneous exterior wall panel and a manufacturing process thereof, belonging to the technical field of prefabricated buildings. Background technique [0002] At present, prefabricated exterior wall panels are generally divided into external-mounted technology and built-in technology. Due to different materials, they are divided into different technical solutions. [0003] At present, the main types of wall panels that can be used as prefabricated external wall panels in China are: load-bearing concrete rock wool composite external wall panels, thin-walled concrete rock wool composite external wall panels, concrete polystyrene composite external wall panels, and concrete perlite composite external wall panels. Wall panels, steel mesh cement insulation sandwich panels, SP prestressed hollow panels, aerated concrete exterior wall panels and vacuum extrusion fiber cement panels (ECP for short). [0004] 1. Load-bear...

AI Technical Summary

Problems solved by technology

[0021] 1. Cracking, slippage, and plane warping caused by the composite type of the current exterior wall, layered composite of different materials, multiple moldings, internal and external multi-layers, different materials, inconsistent temperature deformation, and differences in physical properties, etc., resulting in rain erosion , freezing and thawing, falling off and other disadvantages

[0022] 2. Most sandwich composite wall panels use ordinary concrete as the structural layer, and there are relatively few studies on lightweight aggregate concrete as the surface layer. There is a lack of literature on the point-supported flexural load-bearing performance of composite wall panels, and The basic mechanical indicators of the structural layer required to complete the basic installation and use of the wall panels are not clear

[0024] In summary, the existing technology obviously has inconvenience and defects in actual use, so it is necessary to propose a rigid bone homogeneous exterior wall panel and its manufacturing process to solve the deficiencies of the existing technology
