"sw building system" (sprayed
concrete
sandwich
wall English abbreviation for sprayed concrete sandwich wall) is a This permanent energy-saving technology is integrated into the wall to form a new steel mesh sandwich concrete shear wall structural system. "sw building system" is to install steel mesh sandwich panels prefabricated on special equipment on the beam foundation cast on site, and after installing clamping columns and clamping beams, a concrete layer is sprayed on the steel mesh sandwich panels , and then carry out on-site pouring of clamped beams and clamped columns, so that the poured concrete and the sprayed concrete layer are densely consolidated to form a frame-type lightweight sandwich concrete load-bearing wall. The invention integrates building structure, energy saving and thermal insulation, and the thermal insulation has the same life span as the building. In line with the requirements of housing industrialization, industrial modernization, and component standardization, 70 housing products are completed in factories. The "sw building system" is different from the current energy-saving status quo of using "externally attached" insulation layers on the exterior of the building's main body. Its biggest advantage is that it eliminates the need to repair or replace the insulation layer throughout the building's life cycle. It solves the problems of easy cracking, hollowing, leakage, falling off and other hidden dangers caused by the current common external wall pasting and external insulation layer technology, as well as the short lifespan that causes a large amount of construction waste and a large amount of maintenance investment in the later period. Can directly carry out various exterior wall decoration projects.
Definition of prefabricated structure
PC (precastconcrete) is the abbreviation of prefabricated concrete structure. It uses prefabricated concrete components as the main components and is assembled, connected and partially cast in place. finished concrete structure.
It can be seen from the above that the sw building system does not belong to the prefabricated structure system.
