The height of the assembling racking structure according to the ascension of forklift or other storage and transportation machinery to judge;Integral unity and library type shelf is fixed shelf structure more, its height according to using the general request, usually should not be less than 6 m.Assembling racking structure generally by several vertical and vertical tectonic facies of connecting beam, beam width and length depends on the vertical structure cargo dimensions, width is generally 0.8 ~ 1.5 m, the vertical structure of beam length of 1.0 ~ 4.0 m.
Monolithic structure and the joining together of base frame type shelf structure generally consists of a number of lattice column and the support system of post points limb column spacing distance and direction along the tunnel should be according to the cargo dimensions that.
Assemble type shelf, constructional column construction, fixed shelf structure of lattice column by subsection compression of limb and pillars truss chord and bearing compressive bar first compression member slenderness ratio should not exceed 150, other compression rod and support pressure rod of slenderness ratio should not exceed 200;Tensile component of slenderness ratio should not exceed 350.Shelves pillar shall be set at the bottom of the plate.Assembling racking structure of general facility at the bottom of the constructional column anchor for constructing fixed only;Fixed shelf structure column shall be the basis of anchorage.
