2. Design Basis

  1. Drawing Basis: Plan of Automated Stereo Warehouse Provided by Party A

  2. Standard:  CECS23:90      Code for Design of Steel Shelf Structures

                JB/T9018-99     Code for design of high-rise rack warehouse with rail roadway

                JB/T11270-2011  Technical Conditions for Composite Steel Structure Shelf of Stereoscopic Warehouse

                GB50011-2001    Chinese Code for Seismic Design

  3. The seismic fortification intensity is 6 degrees, the design basic earthquake acceleration value is 0.05g, and the design earthquake is grouped into the first group.

3. Shelf requirements

  1. The following conditions should be satisfied under full load of the rack cross beam.

    Prestress is not allowed.

    No residual deformation is allowed.

  2. The shelf material is made of well-known steel products in China, and the main material is Q235.

  3. Standard parts are of grade 8.8 except anchor bolts and locking nuts.

  4. The color is as follows:

4. Manufacturing Technology of Shelf

  1. The surface of the weld seam of the components shall be welded evenly, and there shall be no defects such as cracks, slag inclusion, welding nodules, burning through, arc pits and needle-like air holes.

  2. The limit error of shape and dimension of fillet weld and weld seam should conform to the relevant provisions of GBJ205.

  3. The shelf surface is degreased, phosphated, washed, dried and electrostatic sprayed. The coatings are made of thermosetting epoxy resin (powder), with an average thickness of 60 microns. The quality of the coatings is in accordance with the GB6807-86 standard, which ensures that the coatings are full and smooth, colorless, and do not allow shrinkage, wrapping and other phenomena.
