Side wall trolley

Abstract

The invention discloses a side wall trolley which comprises a plurality of side wall trolley units spliced lengthways, wherein each side wall trolley unit comprises a trolley moving and fixing system and a steel moulding plate connecting and positioning system. The side wall trolley adopts the design of cantilever connection of a steel moulding plate and a trolley, combines hydraulic jacks, screw jacks and walking systems to realize three-position accurate adjustment, realizes bearing and transmission of load through components such as opposite supporting pipe fittings, lateral screw rod jacks, bearing jacks, tail margin guy cables and anti-floating screw rod jacks, and is stable and reliable in structure. Through the adoption of the side wall trolley, construction of a steel pipe bracket and assembly of moulding plates are not need, thus greatly simplifying construction procedures, improving the mounting speed and reliability of the moulding plates and the construction efficiency, meanwhile reducing labor intensity of workers, greatly saving manual labor, wood and steel pipe brackets and lowering the construction cost.

Description

technical field [0001] The invention relates to a side wall concrete construction equipment, in particular to a side wall trolley which does not need to build a steel pipe support and assemble a wooden formwork during construction of a subway station. Background technique [0002] At present, the concrete construction of the side wall generally adopts the construction method of full-wall bracket method + wooden formwork. This process needs to build a steel pipe support with the same width as the foundation pit in the foundation pit, and then assemble the wooden formwork piece by piece. Therefore, there are the following problems in actual construction: [0003] 1. The amount of lap joint of the steel pipe support is large, and the lap speed is slow; [0004] 2. When installing wooden formwork, the operating space is narrow, the working environment is poor, and the formwork assembly speed is slow; [0005] 3. It is difficult to guarantee the quality of the overlapping of fo...

AI Technical Summary

Problems solved by technology

[0003] 1. The amount of lap joint of the steel pipe support is large, and the lap speed is slow;

[0004] 2. When installing wooden formwork, the operating space is narrow, the working environment is poor, and the formwork assembly speed is slow;

[0005] 3. It is difficult to guarantee the quality of the overlapping of formwork and steel pipe support, and the reliability is poor. When concrete is poured, it is easy to cause deformation of the side wall or concrete leakage;

[0006] 4. Wooden formwork has been assembled many times, and the concrete surface has poor flatness, and joints are prone to misalignment;

[0007] 5. It takes a long time to dismantle turnover materials such as wooden formwork and its brackets, the turnover speed is slow, and the usage is large;

[0008] 6. The technical requirements for workers are high, the labor intensity of workers is high, the number of workers required is large, the efficiency is low, and the labor cost is high
