Embodiment 1

[0023] In order to overcome the existing problems of large self-weight of steel bars in the pier body, high difficulty in prefabrication, long construction time of ordinary tire frames, waste of labor and efficient construction without using the pier body, the present invention provides such as Figure 1-3 Shown is a prefabricated steel frame for a large rectangular cross-section pier body and its use method. The invention improves the prefabrication rate of steel bar segments during pier body construction, saves construction time, optimizes construction efficiency, and reduces safety risks.

[0024] A prefabricated steel bar frame for a large cross-section pier body, including a bottom plate 9, a hydraulic system 1, a bottom hydraulic pushing system 2, a movable pole positioning frame 3, an end main reinforcement positioning frame 6 and a horizontal fixing rod 7. The main rib positioning frames 6 are arranged at both ends of the bottom plate 9, the hydraulic system 1 is set un...

Embodiment 2

[0029] Based on Embodiment 1, in this embodiment, preferably, the bottom plate 9 is in the shape of a rectangular frame.

[0030] Preferably, the bottom hydraulic pushing system 2 is a jack or a hydraulic cylinder.

[0031] Preferably, the upper end of the bottom hydraulic pushing system 2 is provided with a steel backing plate.

[0032] In the present invention, the setting of the steel backing plate ensures that the hydraulic jacking system 2 at the bottom exerts uniform force when jacking up the fabricated steel skeleton, and does not damage the fabricated steel skeleton. The steel skeleton made by the certificate is completely jacked up.

[0033] Preferably, the top positioning device 5 and the bottom positioning device 4 are both positioning scales.

[0034] In the present invention, if figure 2 As shown, the positioning dimension provided by the positioning scale enables the movable pole positioning frame 3 to intuitively and clearly move the distance required during...

Abstract

The invention provides a large rectangular-section pier body steel bar prefabricating jig frame and a using method thereof. The jig frame comprises a bottom plate, hydraulic systems, bottom hydraulic pushing systems, movable vertical rod positioning frames, end main bar positioning frames and horizontal fixing rods, the end main bar positioning frames are arranged at the two ends of the bottom plate, and the hydraulic systems are arranged below the bottom plate and is close to the outer edges of front and back sides of the bottom plate. The multiple bottom hydraulic pushing systems are evenly distributed below the bottom plate, the multiple movable vertical rod positioning frames are arranged between the two end main reinforcement positioning frames, and the upper ends and the lower ends of the movable vertical rod positioning frames are provided with top positioning devices and bottom positioning devices respectively. The movable vertical rod positioning frames move on the horizontal fixing rods, and the two ends of the horizontal fixing rod are connected to two end main rib positioning frames respectively. According to the jig frame and the method, the construction time is saved, labor is saved, the construction risk is reduced, the pier body construction effect is optimized, and it is guaranteed that construction is conducted safely and efficiently.

Description

technical field [0001] The invention belongs to the field of steel bar transportation, and in particular relates to a prefabricated tire frame for large rectangular cross-section pier body steel bars and a use method. Background technique [0002] The prefabricated steel frame is a method of prefabricating steel bars in sections in the construction of the pier body. Due to the different project scales of the pier body construction, the high pier can be constructed by segmental ground prefabrication and overall hoisting. For the prefabricated steel tire frame for the large rectangular cross-section pier below 4 meters, the traditional steel prefabricated tire frame generally uses steel plates to position the steel bars, uses the screw to move, and is hoisted by the crane. Due to the heavy self-weight of the steel bars in the pier body, the prefabrication is difficult. Although the ordinary tire frame meets the requirements, the construction time is long, and after the prefabr...
