When using scaffolding bar accessories to set up the template support frame and other heavy carrier, should comply with the following provisions:
1) The use of door steel pipe scaffolding accessories erected template support frame and other heavy carrier, the value of ≥ 5kN concentrated load point of action should avoid the middle of the door frame beam 1/3 wide range, or the use of additional brackets, double The overlapping measures of overlapping mast frames.
2) When using a fastener and a bowl-type steel pipe scaffolding lever fitting to set up a template support frame and other heavy loaders, the concentrated load acting on the span should not exceed the following values: corresponding to 0.9m, 1.2m, 1.5m and The allowable values for the 1.8m span are 4.5kN, 3.5kN, 2.5kN and 2kN, respectively.
3) The structure of the support frame must be set to ensure the stability of the overall stability of the provisions of the overall pull bar and other pull pull, even wall measures. And according to the different framework, load conditions and control the deformation requirements, to the horizontal bar with the appropriate arch from the amount.
4) The height of the support frame should be adjusted with adjustable base or adjustable top support. When the use of lap pole, the rotating fastener should be the total anti-skid bearing capacity of not less than 2 times the design load set, and not less than 2 Road.
5) with the vertical transport facilities set up the multi-layer transport platform should be based on the actual use of load design, strict control of the pole spacing, and separate frame and set up walls, support pull measures, prohibited with the scaffolding pole sharing.
6) When the template support frame and other heavy loaders set the man work surface, should be set as mentioned above, security protection.
