Single-story lightweight gantry structure refers to the light-welded H-beam (equal section or variable cross-section), hot-rolled H-shaped steel (equal section) or cold-formed thin- Lattice lattice door frame as the main load-bearing skeleton, with cold-formed thin-walled steel (groove, Z-shaped, etc.) for purlin, wall beams; to pressure metal plate Surface; using polystyrene foam, rigid polyurethane foam, rock wool, mineral wool, glass wool, etc. as a thermal
insulation material and the appropriate set of support a light housing structure system. First, what are the characteristics of single-story lightweight gantry structure 1 lightweight light-protection structure using pressure metal plate, glass wool and cold-formed thin-walled steel and other materials, roofing, wall quality are very light. According to the statistics of domestic engineering examples, the amount of steel used in the load-bearing structure of single-storey light-
weight portal frame is 10 ~ 30kg / �O, and its weight is only about 1/20 ~ 1/30 of that of reinforced concrete under the same span and load Due to the light weight of the structure, the corresponding foundation can be made smaller and the cost of foundation treatment lower. At the same time, the seismic response of the structure under the same seismic intensity is small. However, when the wind load is larger or the house is higher, the wind load may become the
