Technical field

The utility model relates to a formwork turning device for a climbing scaffold for chimney construction.

Background technique

The turnover formwork of existing chimney construction is to adopt to set up scaffolding along chimney body of wall, fix formwork again, carry out the pouring of concrete. Its disadvantages are: the scaffolding and turning formwork equipment is complicated, the operation is laborious, the work efficiency is slow, and the quality cannot be guaranteed.

Utility model content

The purpose of this utility model is to overcome above-mentioned inadequacies and provide the turning formwork equipment of the climbing scaffold of chimney construction, scaffolding and turning formwork equipment are compact, easy to operate, work efficiency is fast, and quality is guaranteed.

The technical scheme adopted by the utility model to solve its technical problems is: the turning formwork equipment of the climbing scaffolding of chimney construction, the inner wall of chimney building is used to fix support frame and expansion joint with bolts, and the cross brace is on the inner diameter of chimney. A circular base is fixed on the supporting frame, and there is a round hole on the base. There is a movable turntable above the base. A plane bearing is installed between the movable turntable and the base. There is a shaft on the movable turntable extending in the round hole of the base to make it rotate. . There is a latch at the edge position between the movable turntable and the base, and when the movable turntable does not require rotation, the latch is inserted. A guide sleeve is fixed on the movable turntable. The upper end of the guide sleeve is connected with the beam, and a hydraulic jack is arranged above the beam. A supporting steel rod is installed on the ground, and the supporting steel rod passes through the base, the movable turntable, the guide sleeve, the beam and the hydraulic jack. Two elevating frames are respectively installed on both sides of the beam, and movable outriggers are arranged on the elevating frames, and the movable outriggers are respectively connected with the inner formwork and the outer formwork of the chimney. After the formwork is installed, concrete is poured, and after the concrete is set, the formwork is removed, and the hydraulic jack climbs up on the supporting steel rod, driving the lifting frame to lift upwards, and the formwork is continued to be installed.

The effective effect of the utility model is that the formwork equipment of the climbing scaffold used in the chimney construction of the utility model, the scaffolding and the formwork equipment are compact, easy to operate, fast in work efficiency, and guaranteed in quality.

Specific implementation method

The turn-over formwork equipment of the climbing scaffold of chimney construction uses bolted support frame (15) and expansion joint (3) at the inner wall of chimney building, and cross brace is on the inner diameter of chimney. A circular base (14) is fixed on the support frame (15), a circular hole is arranged on the base (14), and a movable turntable (12) is arranged above the base (14), between the movable turntable (12) and the base (14) Plane bearing (13) is housed, and axle stretches in the circular hole of base (14) and makes it rotate on movable rotating disk (12). There is a latch at the edge position between the movable rotating disk (12) and the base (14), and when the movable rotating disk (12) does not require rotation, the latch is inserted. A guide sleeve (11) is fixed on the movable rotating disk (12). The upper end of guide sleeve (11) is connected with crossbeam (8), and hydraulic jack (9) is equipped with above crossbeam (8). Support steel rod (10) is installed on the ground, and support steel rod (10) passes base (14), movable rotating disk (12), guide sleeve (11), crossbeam (8), hydraulic jack (9). Two elevating frames (5) are respectively installed on crossbeam (8) both sides, and movable support leg (7) is housed on elevating frame (5), and movable support leg (7) is connected with the inner formwork, the outer formwork of chimney respectively. After formwork (6) installed, pouring concrete, after concrete set, remove formwork (6), hydraulic jack (9) climbs on support steel bar (10), drives hoist frame (5) to promote upwards, continues to install formwork.
