Abstract

The invention relates to a steel skeleton expanded rock pressure relief plate and a pressure relief structure using the same. The pressure relief plate comprises a steel skeleton and a steel wire net laid on the steel skeleton, wherein a expanded rock lightweight core material is arranged on the steel skeleton and the steel wire net; a cement-based composite impermeable protective layer is arranged on the expanded rock lightweight core material; a main rib protective layer is arranged below the steel skeleton and the steel wire net; the weight per unit area of the steel skeleton expanded rock pressure relief plate is 40 to 50 kg/m<2>, and the pressure relief threshold value of the steel skeleton expanded rock pressure relief plate is about 8.0 to 10.0 KN/m<2>; the expanded rock lightweight core material is a 350-grade to 450-grade expanded rock core material; the main rib protective layer is 15 to 20 mm in thickness; the cement-based composite impermeable protective layer is 1 to 3 mm in thickness. The steel skeleton expanded rock pressure relief plate provided by the invention has the characteristics of heat preservation, fire resistance, sound insulation, pressure relief, load-bearing property and the like. Through inspections on a series of dynamic destruction tests, the pressure relief plate consisting of the expanded rock has excellent pressure relief performance under the action of dynamic load.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a steel frame puffed stone pressure relief plate and a pressure relief structure utilizing the same. Background technique [0002] In the past, asbestos tiles were used for light pressure relief and light fragile roofs. Due to the presence of harmful and toxic substances in the production process, the country does not allow them to be used. At present, more substitutes are used in the project for profiled steel plate, sandwich panel and solar panel. Profiled steel plates and sandwich panels can meet the requirements of light weight, but do not meet the requirements of fire protection, durability and fragility. The solar panel has poor durability and cannot meet the thermal insulation requirements. In this way, no suitable pressure relief plate can be selected in actual engineering. [0003] The steel skeleton puffed stone pressure relief plate developed and produce...
