A lightweight self-insulating prefabricated panel system for grid roofs

Abstract

The invention provides a light self-insulation prefabricated slab system for grid roofs. The system is characterized in that purlins are unidirectionally (along the length or width direction of the building) arranged on the top chord of a grid; a constant-size light self-insulation prefabricated slab is covered between two adjacent purlins and is vertical to the purlins; the spacing between the two adjacent purlins is matched with the length of the constant-size light self-insulation prefabricated slab; one end of the constant-size light self-insulation prefabricated slab is fixedly put on one purlin and the other end thereof is fixedly put on the adjacent purlin; gaps are reserved between the constant-size light self-insulation prefabricated slabs which are put on the same purlin, are arranged in the direction vertical to the purlins and are arranged oppositely; and the adjacent constant-size light self-insulation prefabricated slabs are butted with each other in parallel in the direction parallel to the purlins. The system is convenient to transport and maintain, is quick to construct, is suitable for roofs or wall surfaces with complex load conditions, and has strong wind resistance and high reliability, thus improving the rigidity of the whole roof system.

Description

technical field [0001] The invention relates to the technical field of civil engineering prefabricated structural components, in particular to a lightweight self-insulating prefabricated panel system for grid roofs. Background technique [0002] The grid roof structure has been widely used in long-span buildings, and has the advantages of beautiful appearance, energy saving, and quick construction. In particular, the grid structure itself and the lightweight roof panel can give full play to the advantages of the grid structure. Roof panels with lightweight self-insulation characteristics have become the mainstream of structural component development today. In addition to load-bearing, this type of component also has the function of heat preservation and energy saving. It can meet the requirements of building heat preservation and energy saving without additional heat preservation treatment. According to the composition of materials, production technology process and structu...

Problems solved by technology

The relatively long period of production, transportation and installation of customized boards will affect the quality and installation progress of the boards to a certain extent

[0015] The steel skeleton is not only the main force-bearing member but also a one-time formwork required for panel making, which requires a large amount of steel, low degree of automated production, and low production capacity

[0016] Generally speaking, compared with composite color steel plates, steel skeleton plates have the advantages of fire prevention, large load-bearing capacity, and long service life, and are suitable for permanent buildings. However, due to customized production, low production efficiency and high cost affect popularization and application.
