Description

Technical Field

[0001] The utility model relates to the technical field of formwork supports, in particular to a formwork support device for bridge construction. Background Art

[0002] In the construction of bridges, it is usually necessary to use multiple supporting members to support the formwork from both the inside and the outside, and then pour concrete. After estimating that the concrete has hardened, the formwork is removed piece by piece. The commonly used formwork fixing method is to first fix the building formwork, then reinforce the outside of the formwork, and then carry out pouring.

[0003] An existing formwork support bracket for bridge construction uses a setting method in which a first support rod and a sleeve cooperate. Through the cooperation of the first support rod and the second support rod, the bearing plate drives the ball to rotate in the circular groove of the main beam, and then the relative fixation of the slide rail and the first support rod is achieved through a positioning pin. At this time, the inclination angle adjustment of the bearing plate is completed. The support angle of this support bracket is convenient to adjust, and the angle of the bearing plate can be adjusted according to the shape of the lower surface of the bridge. However, adjusting the support angle of the bearing plate by rotating the sleeve is not convenient enough. When the upper load is large, the sleeve may reverse under the action of pressure, affecting the support effect. For this reason, a formwork support device for bridge construction is proposed for improvement. Summary of the Utility Model
