Description

Technical Field

[0001] The utility model relates to a supporting device, and in particular to a temporary load-bearing supporting device used in a support removal stage. Background Art

[0002] In the construction of the main civil engineering project, it is usually necessary to dismantle the support for the foundation pit construction. The current practice is to directly build a full-height scaffolding at the bottom of the concrete beam to support it, and then fix the frame through overall tensioning to ensure that it has sufficient bearing capacity and anti-lateral stiffness. The full-height scaffolding is connected by multiple "well"-shaped sub-frames.

[0003] The existing dismantling and supporting full-height scaffolding used in foundation pit construction has high requirements on the material of steel pipes and fasteners, which increases the cost of material procurement and limits the range of materials available. Moreover, in order to ensure the stability of the structure, it is necessary to take a variety of reinforcement measures, such as scissors support, column holding measures, lateral fixed support measures, etc., which increases the complexity and cost of construction. In addition, due to the large span of the full-height scaffolding, it is not conducive to the turnover of the construction site, and it must be completely dismantled and rebuilt, which increases the labor cost and time cost. In addition, the disassembly and assembly process requires large-scale assembly and installation, which is time-consuming and labor-intensive, and the disassembly and turnover are difficult. Unified turnover is impossible, which may lead to delays in construction progress and safety hazards. In addition, during the demolition stage of the underground retaining structure, the support beams often need to be cut off in sections. The cut-off part of the support beam will generate its own load. If it is not supported, it may cause structural instability.

[0004] In order to solve the above technical problems, the utility model patent with patent number CN201920683288.5 discloses a support horse stool device, which includes a support beam, an adjustment component and a support base, and the support beam and the adjustment component are stacked at one time in the vertical direction. The above device can be quickly disassembled and assembled, convenient for transportation, and can be processed and manufactured off-site, but the length of the above device is limited. However, the segment length of the concrete support beam when the concrete support beam is segmented during the demolition stage of the underground enclosure structure is determined according to the on-site conditions. Sometimes the segment is relatively long, and sometimes it is relatively short. The support device with limited length has a poor support effect for the concrete support beam with a longer segment; and the thickness of the support beam of the above support horse stool is too large, and the installation of the support beam and the adjustment component is also troublesome. In addition, the above support horse stool is a fixed structure, which is not very convenient to move. After use, it needs to be disassembled before it can be moved, and then assembled at the next location, and the cut concrete support beam cannot be transported. Utility Model Content
