Description
Technical Field
The invention relates to an external wall panel, in particular to a polyphenyl concrete sandwich composite heat-preservation batten filled external wall.
Background
The outer wall sandwich heat insulation is to fill a material with heat insulation and heat insulation performance between an inner leaf wall and an outer leaf wall of a building outer wall, so that the outer wall has a good heat insulation effect.
The traditional outer wall with sandwich insulation engineering is divided into two types: one is a bearing stress outer wall, which comprises a masonry bearing wall and a cast-in-place reinforced concrete shear wall; the other is a prefabricated reinforced concrete outer wall.
For the stressed outer wall of the masonry load-bearing wall containing the sandwich insulation, the polystyrene board is pre-filled in the masonry block body and then is built on site, and the defects of low construction speed, cold and hot bridge formed by building mortar and no waterproof performance exist. Belongs to the traditional construction process and does not belong to the assembly type technical range.
For the stressed outer wall of the cast-in-place reinforced concrete shear wall with the sandwich insulation, the polystyrene board is installed when a template is bound on a construction site, then a steel bar is bound, and concrete such as an SW system, a CL system and the like is cast on the site. The method has the defects of low construction speed, complex node and low standardization rate, belongs to the traditional construction process, and does not belong to the technical range of assembly type.
A prefabricated reinforced concrete outer wall belongs to a novel wall body after an assembly type building is widely applied, and has two types according to the processing technology of a sandwich heat-insulation polystyrene board: one type does not contain heat insulation performance, only aims to realize the purpose of adding the sandwich polystyrene board in the prefabricated reinforced concrete outer wall, only aims to reduce the weight of hoisting weight, and needs to be additionally constructed on site after the prefabricated outer wall is installed on site and the heat insulation, the water resistance and the building outer decorative layer are finished;
the other type of prefabricated reinforced concrete sandwich outer wall is a heat insulation system which is formed by placing heat insulation materials such as polystyrene boards in the middle of a concrete wall body and pouring the heat insulation materials and the whole wall body together in a prefabricated part factory. In the wall body, the inner leaf wall is a stressed structure layer, the middle part is an insulating layer, and the outer leaf wall is a protective layer, wherein the protective layer can be made into various effects such as clear water, paint, tiling, stone and the like in a factory. The integral performance, the heat preservation performance, the sound insulation performance, the fire prevention performance and the waterproof performance of the wall all meet the relevant requirements, but because the inner wall is a reinforced concrete wall body and is connected with the structural main body into a whole, the lateral stiffness of the wall body is considered, the wall body belongs to the structural main body wall body in theory, and does not belong to a light filling wall body, and the defects of high processing difficulty, heavy weight, high on-site hoisting and installation difficulty and the like exist.
According to the analysis of the external wall material, a light-weight filling external wall panel which is small in processing difficulty, simple and convenient to assemble on site and capable of meeting the requirements of heat preservation, sound insulation, fire prevention and water prevention is urgently needed in the market at present, and conditions for market demands are created for the invention.
