Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a steel tripod construction platform for the edge of a concrete structure. Background Art

[0002] At present, for construction projects such as river courses and water conservancy, the use of retaining walls has become more and more common. Considering economic cost savings, the retaining wall structure needs to consider water retaining standards, structural safety, seepage safety, etc., and at the same time needs to bear the support for bridge body maintenance. The existing structure using a single pile or a single-sided wall is only a block structure composed of concrete, which plays a role in blocking water. If maintenance operations need to be carried out on the bottom part of the bridge, a steel pipe scaffold needs to be installed on the original retaining wall. The existing steel pipe scaffolds are often formed by cross-connecting steel pipes, with relatively high manufacturing costs. At the same time, the steel pipe scaffold equipment is exposed outdoors for a long time, and due to reasons such as rust at the joints of the steel pipes, structural risks are likely to occur. If the steel pipe scaffold is disassembled, due to the cross-arrangement of multiple steel pipes, the disassembly and installation are extremely inconvenient. It often requires a lot of manpower to load and unload within a specific time. This increases the usage cost and at the same time cannot meet the requirements of being installed and disassembled at any time, with poor flexibility. Due to the complexity of disassembling the traditional steel pipe scaffold, the operation efficiency is low. Summary of the Utility Model
