Installation scheme of cable bridge in an underground garage
1. The underground bridge is wide and there are many cables to be laid. The support must be solid, firm and reliable, followed by beautiful and practical. Therefore, angle steel support must be used to strengthen its firmness. As the construction unit requires the use of suspender support, after comprehensive consideration, it is decided to use angle steel support and suspender support together. 2. There are many bridges in the underground garage, which are beautiful, practical and simple. Bridge supports are divided into two types: the first type of shared support: when the main cable bridge and the fire bridge go together, they share a support. This support needs to load all the weights of the bridge, main cable and weak current cable, so the specification of the support steel is large. The second type of single support: this support only loads the weight of the small bridge and small cable, Therefore, the specification of support steel is small. 3. Angle steel support and suspender support shall be installed. The angle steel support shall be installed at the structural beam, responsible for the stability of the bridge in the horizontal direction, to avoid the displacement and deformation of the support during cable laying. Secondly, it is responsible for the vertical load of bridge and cable here. The hanger bracket is responsible for the vertical load of the bridge and cable at the top plate.
