Embodiment 1
[0037] like Figures 1~5 Among them, a multi-rib three-way prestressed prefabricated trough body reinforcement installation platform, the main beam trough body 1 is located on both sides, and a plurality of secondary beam platforms perpendicular to the main beam trough body 1 are arranged between the main beam trough bodies 1 The frame hole 6, the sub-beam installation area frame 2 is formed between each sub-beam frame hole 6;
[0038] The depth of the two ends of the main beam groove body 1 is greater than the depth in the middle, and there are also end reinforcement grooves 9 near the two ends of the main beam groove body 1. The end reinforcement grooves 9 are parallel to the secondary beam platform holes 6. The depth is greater than the depth of the secondary beam stand hole 6 . In a preferred solution, the main beam groove body 1 , the secondary beam platform hole 6 and the end reinforcement groove 9 are all located below the ground 11 . With this structure, it is conven...
Embodiment 2
[0047] On the basis of Example 1, as Figures 1~6In the above, an installation method of the above-mentioned multi-rib three-way prestressed prefabricated groove body reinforcement installation bench, comprising the following steps:
[0048] 1. According to the structural dimensions of the long-span multi-rib prefabricated trough body, the detailed dimensions of the special bench for the installation of the multi-rib steel bar for the large-span trough body are designed. 9. Before excavation, use measuring instruments to accurately set out;
[0049] Preferably, the main girder groove body 1 is excavated mechanically, and the bench 2 in the secondary girder installation area is excavated manually.
[0050] 2. The base layer of the steel bar installation platform is hardened and leveled, the horizontal surface is made of concrete, the facade is made of brick structure, and the surface of the brick structure is set with mortar plastering;
[0051] 3. Install two lateral elevati...
