Bridge support problem
Thread Content
I would like to ask, when installing the bridge, what distance should be used as a support point? Is there any special specification? For example, 800* 200 bridge
When the bridge is laid horizontally, the support spacing is generally 1.5-3m. When it is laid vertically, the spacing between the supports fixed on the building structure should be less than 2m.
It seems there are no regulations! The specific decision should be made based on the situation on site. First of all, it should be sturdy and durable, then beautiful and elegant, and thirdly, material saving.
"Code for Construction and Acceptance of Automated Instrument Engineering" GB 50093-2002 stipulates that "When installing cable troughs and protective tubes, the spacing between metal brackets should be 2mm, and brackets should be installed at corners, terminals and other required locations. ”

The specification says 1.5 to 2m, but it also depends on the maximum span of the bridge you choose. If there is a long span, the distance can be larger, but you must ensure that there are supports at both ends of the bridge. You can check the manufacturer's sample for this. Some have written support distances.
