A lightweight self-insulating prefabricated panel system with shear key structure

Abstract

The invention provides a light self-insulation prefabricated slab system with shear connector structures. The system is characterized in that purlins are vertical to a building main structure supporting member; the purlins are arranged in parallel; a constant-size light self-insulation prefabricated slab is covered between two adjacent purlins and is vertical to the purlins; 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 and are arranged oppositely; the adjacent constant-size light self-insulation prefabricated slabs are butted with each other in parallel; and the seams of the two adjacent constant-size light self-insulation prefabricated slabs are connected by shear connector structures. The system is convenient to transport and maintain, 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 with a shear key structure. Background technique [0002] Structural components with lightweight self-insulation features, such as lightweight roof panels and wall panels, have become the mainstream of today's structural components. 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 structural system, it can be divided into composite color steel plates and steel skeletons. Class plates etc. [0003] There are two major systems of light panels in the prior art: [0004] The first is the purlin-free system, mainly comp...

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] There is a gap between the plates in the width direction of the plate, which makes it difficult to form a stressed whole between the plates. When the external force acts, it is easy to cause inconsistent deformation of the plates

[0017] Generally speaking, compared with composite color steel plates, steel frame 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, the production efficiency is low, the cost is high, and the plate seam treatment method is flawed. , affecting promotional applications
