Prestressed tension auxiliary construction stage device

Abstract

The invention discloses a prestressed tension auxiliary construction stage device used for engineering such as railways, roads, industrial buildings, water conservation, energy and rock and soil anchorage. The prestressed tension auxiliary construction stage device comprises an outer formwork, an inner formwork, an anchor pedestal, a tensioning anchor and a pulley component, the outer formwork and the inner formwork consist of scaffold steel pipes, the inner formwork is placed in the outer formwork, the anchor pedestal is placed on the inner formwork, the tensioning anchor is placed on the anchor pedestal, the pulley component is connected onto the outer formwork, and universal rotating wheels are disposed at the bottom of the outer formwork. The anchor pedestal consists of square timber, a reinforcing mesh and reinforcing guardrails, the reinforcing mesh is placed on the square timer, and the reinforcing guardrails are placed on the reinforcing mesh. The prestressed tension auxiliary construction stage device is simple in structure and convenient to operate, and materials of the prestressed tension auxiliary construction stage device are available easily. In addition, engineering practices show that tensioning speed is fast, construction is safe, and construction expense is lowered after the novel stage device is used.

Description

technical field [0001] The invention belongs to the technical fields of railways, highways, industrial buildings, water conservancy, energy and geotechnical anchoring, and specifically relates to a bench device made of on-site materials, which is used for auxiliary prestressed tensioning. Background technique [0002] After decades of engineering practice and continuous research, prestressing technology has developed into a relatively mature engineering technology. Its principles are widely used in railway and highway bridge engineering, industrial housing construction, and water conservancy and geotechnical engineering. In slope anchoring engineering, it has broad development prospects and practical value. [0003] Applying prestress to the steel strand is the key process of prestress technology, so the quality control, safety assurance and construction progress of prestress stretching are particularly important. Usually, when the prestress is stretched, a temporary steel ...

AI Technical Summary

Problems solved by technology

With the large-scale promotion of prestressing technology, this traditional scaffolding can no longer meet the needs of construction progress and construction safety.

For example, in the prefabrication of centralized box girders in high-speed railways, the erection of scaffolding and tensioning can no longer meet the construction requirements, the crane cannot assist in the tensioning of cast-in-place continuous box girder saw-tooth grooves, and the tension anchors are difficult to lift into place, etc., all need to be solved; At the same time, during tensioning operations with tight construction schedules and heavy tasks, a large number of construction personnel and mechanical equipment on site work at the same time, which not only causes construction interference, affects the construction progress, but also easily induces safety accidents
