T/GYDX 001-2019 Steel lamppost

Scope

Main technical content: 5.2.1.1.2 Dimensional tolerances for the overall length of top-mounted light poles. The dimensional tolerances for the overall length of top-mounted light poles shall meet the requirements of Table 1. 5.2.1.1.3 Dimensional tolerances for the overall length of cantilever-mounted light poles. The dimensional tolerances for the overall length of cantilever-mounted light poles shall meet the requirements of Table 1. Note: Independent cantilevers can be fixed to light poles via cantilever connectors. 5.2.1.2 Wall thickness of light poles. The wall thickness of light poles shall comply with the design specifications. For light poles made from sheet metal, the thickness tolerances of the sheet metal shall meet the requirements of GB/T 709. 5.2.1.3 Cantilever overhang length. a) The cantilever overhang length shall be determined by the specific road conditions, but the value of w shall not exceed h/4. b) The recommended cantilever overhang length specifications are 1.0 m, 1.25 m, 1.5 m, 2.0 m, 2.25 m, 2.5 m, 3.0 m, and 3.5 m. c) The dimensional tolerances for the cantilever overhang length shall be ±1.5%w. 5.2.1.4 Luminaire installation angle. a) The luminaire installation angle shall be determined by the specific road conditions, and the recommended optimal specifications are 5°, 8°, 10°, 12°, and 15°. b) Under no-load conditions, the tolerance for the luminaire installation angle shall be ±2°, and the offset between the cantilever axis and the installation axis shall not exceed ±2°. 5.2.1.5 Dimensions of luminaire connectors. The diameter d1 of luminaire connectors shall meet the requirements of Table 2. For luminaire connectors of integrally formed conical rods, the dimensions are shown in Figure 2, and the diameter d1 shall be measured at point l1.
