Integrally decorated abnormity prefabricated core sandwich concrete panel

Abstract

The invention provides an integrally decorated abnormity prefabricated core sandwich concrete panel comprising a right angle wall, a linear wall and a joint portion; the right angle wall comprises a first board wall, a second board wall and a corner board wall forming an integral moulding structure, wherein one ends of the first and second board walls are connected with the corner board wall, and the other ends are connected with the linear wall through the joint portion. In the prior art, joint mounting is needed in corners when the panels are installed, the wall surface secondary decoration construction operation is complex, and the surface layer has shedding, water leakage and cracking quality problems; the integrally integration sandwich panel can be directly used, is easy to mount, reliable in quality, and durable.

Description

technical field [0001] The invention belongs to the field of building prefabricated wall panels, and in particular relates to an integrated decorative special-shaped prefabricated sandwich concrete wall panel. Background technique [0002] At present, the prefabricated lightweight wall panels traditionally used in buildings mainly include the following categories: ALC panels: porous concrete forming panels (including steel mesh sheets) made of fly ash, cement, lime, etc. as the main materials through high-pressure steam curing ). Light in weight, good in thermal insulation and sound insulation, it is mainly used as non-load-bearing enclosure wall panels and roof panels; there are no special-shaped corner panels, and the corners are bonded and butted with adhesives before surface treatment. [0003] ASA board: It is a building board made of fly ash as filler, cement as gelling agent, and alkali-resistant glass fiber mesh or steel mesh as reinforcement. Light weight, thermal...

Problems solved by technology

[0004] The above-mentioned lightweight prefabricated wallboard bases can be used for non-load-bearing enclosure walls; when used for exterior wall corners, two wallboards need to be bonded and spliced, and then the surface is pasted with grid cloth, second batch embedding and paint construction. The part is prone to hidden dangers such as cracking and water seepage

There is no decorative surface on the outer surface, and putty is required for surface decoration, and cracks are likely to be caused at the lap joints; the surface strength is insufficient, and it is easy to break during transportation; the installation with the structure is more complicated
