Description

Technical Field

[0001] The utility model relates to the field of blue steel sheets, in particular to a shock-resistant blue steel sheet. Background Art

[0002] Steel structure houses are easy to assemble, bear heavy loads, and can be reused. They are popular among enterprises that build standardized factories. The components for assembling steel structure houses include profiles, connectors, and screws. There are currently two main types of profiles: C-shaped profiles and U-shaped profiles. U-shaped profiles are used as components for the roof and floor, and C-shaped profiles are used as components for the columns. The structure of the U-shaped profile consists of a panel and two side panels. The structure of the C-shaped profile consists of a panel, left and right side panels, and the left and right side panels curled inward. The heights of the two side panels are the same. The U-shaped profile and the C-shaped profile are connected and assembled into a steel structure house through connectors. Most of these connectors are made of blue steel sheets. Currently, most blue steel sheets are made of a single material, which makes their seismic performance poor during the construction of the house. For this reason, we have proposed a seismic-resistant blue steel sheet. Utility Model Content

[0011] Preferably, the thickness of the shock absorbing plate is 30 mm, and the shock absorbing plate is made of elastic metal material.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a seismic-resistant blue steel sheet, which has the following beneficial effects:

[0014] 1. The seismic-resistant blue steel sheet evenly distributes the pressure through the fishing net-like grids on the upper blue steel sheet and the lower blue steel sheet, so that the blue steel sheet is evenly stressed as a whole, preventing damage caused by excessive local pressure, and absorbing vibration force through the wave-like ups and downs of the protrusions, thereby achieving the seismic resistance of the overall structure of the blue steel sheet.

[0015] 2. The density of aluminum in the seismic-resistant blue steel sheet is lower than that of steel. The setting of the aluminum layer reduces the overall weight of the blue steel sheet and reduces the production cost. The setting of the galvanized layer, the chrome-plated layer and the waterproof layer improves the overall corrosion resistance and friction resistance of the blue steel sheet, thereby extending the service life of the blue steel sheet.
