Reusable hydraulic combined special-shaped steel template and disassembly method thereof

Abstract

The invention discloses a reusable hydraulic combined special-shaped steel template and disassembly method thereof. The steel template comprises an arc section bent frame, a straight section bent frame, a hydraulic main pipe, a hydraulic oil cylinder, a circular arc panel and a plane panel. The hydraulic main pipe is the same as the bending shape of the elbow section of the pump station flow channel, and the hydraulic main pipe penetrates respectively straight through the center of the arc section bent frame and the straight section bent frame; the hydraulic oil cylinder comprises a radial hydraulic oil cylinder, a central straight hydraulic oil cylinder, a lateral hydraulic oil cylinder and an oblique hydraulic oil cylinder; each hydraulic cylinder is provided with a metering valve. The Hydraulic combined special-shaped steel template capable of being repeatedly used and disassembling method thereof ingeniously uses hydraulic oil cylinder as the support and shaping structure of the elbow section of the pump station flow passage , and corrects the deformation of the arc section bent frame, the straight section bent frame, the circular arc panel and the plane panel to ensure the position accuracy of the template by driving the hydraulic oil cylinder through the hydraulic oil to adjust the corresponding stroke or length, , the steel die can be automatically put up or disassembledafter the concrete takes shape, so that the steel template can be repeatedly used and the positioning accuracy is high.

Description

technical field [0001] The invention relates to a construction temporary support structure for forming concrete pouring, in particular to a reusable hydraulic combined special-shaped steel formwork and a dismantling method. Background technique [0002] As a complex structure of special-shaped ordinary concrete with large volume and variable cross-section, in the traditional construction, the elbow section of the flow channel of the pump station often has honeycomb, pitting, cracks, misalignment, and flatness due to the formwork material, formwork process, and erecting formwork technology. Quality problems such as excessive size will seriously affect the performance and efficiency of the pump unit. Therefore, to improve the quality of concrete, it is necessary to study the formwork material and manufacturing methods and processes. [0003] As a widely used traditional wood formwork, it has many advantages, such as convenient on-site processing, quick installation, low cost, ...

AI Technical Summary

Problems solved by technology

However, for the special-shaped and complex spatial surface of the elbow section of the pumping channel, although the concrete poured with the new steel formwork for the first time basically meets the quality requirements, however, the same new steel formwork is used for the concrete pouring of multiple identical runners. On the one hand, the amount of steel used is larger, the project cost is higher, the production efficiency is lower, and the construction period is longer, which leads to the delay of the construction period of the pumping station for flood control, and the risk of flood control is greatly increased

On the other hand, the steel formwork is deformed after disassembly, and the secondary positioning is not accurate, so it is inconvenient to reuse

If the traditional construction method is used to pour the concrete of the same pump flow channel with the old steel form again, there will be certain quality defects, and the quality defects of the concrete will continue to accumulate with the repeated use of the old steel form, thus affecting the operating life of the flow channel and Unit efficiency
