Angle-adjustable-type guy cable system of ultra-high steel pipe support

Abstract

The invention discloses an angle-adjustable-type guy cable system of an ultra-high steel pipe support. The angle-adjustable-type guy cable system comprises an adjustable-type jack device, a steel pipesupport guy cable, a reinforced concrete ground anchor tensioning end, a connector and a steel pipe support anchoring end. The steel pipe support anchoring end is connected with the adjustable-type jack device through the steel pipe support guy cable, and the reinforced concrete ground anchor tensioning end is rotationally connected with the adjustable-type jack device through the connector. Theadjustable-type jack device comprises a tensioning equipment storing box and a jack placed in the tensioning equipment storing box. A reserved hole is formed in the upper end of the tensioning equipment storing box, and the steel pipe support guy cable penetrates through the reserved hole and is fixed into the jack through a clamping piece. According to the angle-adjustable-type guy cable system,in the prestress applying process, the tensioning angle is automatically adjusted, adjusting can be conducted in different planes, and safety, stability, convenience and rapidness of construction areensured.

Description

technical field [0001] The invention relates to a fixing device for a building bridge, in particular to an angle-adjustable cable wind system for an ultra-high steel pipe support. Background technique [0002] With the improvement of modern bridge technology, more beautiful bridges are pursued, and bridge construction is more complicated. Construction units often use ultra-high steel pipe supports as temporary facilities to cooperate with bridge construction, which greatly facilitates bridge construction. Generally, steel pipe supports with a height of more than 50m are super-high Steel pipe support, the stability of the steel pipe support decreases as the height increases. However, when fixing similar ultra-high steel pipe supports, they are often fixed by simple cable wind ropes, and tension is not applied to the steel pipe support in advance to offset its own overturning force and the external force during construction, or the value of the prestress applied to the steel p...

Problems solved by technology

However, when fixing similar ultra-high steel pipe supports, they are often fixed by simple cable wind ropes, and tension is not applied to the steel pipe support in advance to offset its own overturning force and the external force during construction, or the value of the prestress applied to the steel pipe support does not match. , leading to insufficient or excessive prestressing, there is a great potential safety hazard, so it is necessary to develop an angle-adjustable cable wind system for ultra-high steel pipe supports, which can automatically adjust the tension angle during construction, and apply accurate, Reliable prestressing increases the stability of the steel pipe support and ensures safety during construction
