The invention discloses an external prestress tie bar cable supporting and guiding device which comprises two angle irons, through bolts, pulleys and a connecting steel plate. Each angle iron comprises a first flange plate and a second flange plate which are arranged in an L shape, the first flange plates of the two angle irons are arranged in parallel in a spaced mode, pulleys are arranged on thetwo first flange plates through opposite-penetrating bolts and used for supporting the prestress tie bar cables, and the two ends of the connecting steel plate are fixedly connected with the tops ofthe first flange plates respectively. According to the supporting and guiding device, a pair of angle iron connected with a prestressed bridge serves as a supporting framework, the prestressed tie barcable is limited through the idler wheels and the connecting steel plates, long-distance swinging of the prestressed tie bar cable can be limited, and movement of the prestressed tie bar cable in thelength direction is not hindered; potential safety hazards caused by free shaking of the prestress tie bar cable can be avoided, prestress adjustment is facilitated, and the device has the advantagesof being convenient to install, high in construction efficiency, safe and reliable.
Description
technical field [0001] The invention relates to an external prestressed tie rod cable support and guide device, which belongs to the technical field of bridge prestress. Background technique [0002] With the progress of bridge engineering construction in our country, prestressed structure bridges, as a bridge construction method that improves bridge stress through structure and reinforces the bridge itself without affecting its normal use, has become the mainstream of bridge engineering today. Prestressed technology is currently It is widely used in various fields of engineering, and has been favored in the field of bridges in recent years due to its active bearing, convenient construction, and excellent results. In prestressed bridges, external prestressed tie rods are often used outside the bridge, but the external prestressed tie rods are relatively long, and the position swing is relatively large during layout and installation, and the force is not uniform.
