Steel frame light-duty panels, steel frame light-duty floor panels, steel frame light-duty roof panels, steel frame light-duty grid panels (including gutter panels), reference standards19cj20/19cg12。

   Application Scope: Seismic fortification intensity less than or equal to in non-earthquake areas8Industrial and civil construction in the degree region.

  Steel frame lightweight roof and floor panels are suitable for industrial and civil buildings in Category 1 environments with non-corrosive media. Steel frame lightweight external wall panels are suitable for environments in Category2bLight industrial buildings.

  Component surface temperature is less than or equal to100Industrial and civil buildings. Steel frame lightweight floor slabs are suitable for additional floor slabs in industrial and civil buildings that only bear vertical loads, as well as for pier and bridge deck slabs. Steel frame lightweight exterior wall panels are suitable for buildings with heights not exceeding30mIndustrial partition panels, non-load-bearing wall cladding mounted on steel or concrete structures.

   Material and Performance:

   Steel: The main and end ribs are made of cold-formed thin-walled steel. The auxiliary ribs and reinforcing ribs are made of cold-formed thin-walled steel or ordinary hot-rolled angle steel, channel steel; the embedded parts are made of ordinary hot-rolled steel plate. The selected steel materials areQ235B,Design value for cold-formed thin-walled steel strengthf=205N/m㎡, steel strength design valuef=215N/m㎡。

  Rebar: The tensile reinforcement and distribution reinforcement use cold drawn low-carbon steel wire mesh. Design value of compressive strength for cold-rolled low-carbon steel wiref=320N/m㎡。

  Welding rods: UsedE43Type welding rods.

  Light steel material concrete: UtilizingLC15Axial compressive strength design valuefc=7.2N/m㎡。

  The core board is made of modified cement perlite composite core material (also known as expanded stone lightweight energy-saving material).

The fire resistance limit of the steel frame light board core material is2.0hFirewall panels are designed separately according to the specific project.
