Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a suspended tie beam steel bar support structure for bridge construction using water. Background Technology

[0002] Bridge construction is a branch of civil engineering, mainly involving the surveying, design, construction, maintenance, and inspection of bridges, as well as the scientific and engineering technologies researching this process. The development of bridge engineering depends primarily on the demands of transportation. Suspended beam steel bar construction is a method mainly used in bridge construction, especially in cap beam construction. This method utilizes steel bars as cantilever supports, and through reasonable construction organization and technical measures, efficiently completes cantilever construction while ensuring construction quality. During the construction of suspended beam steel bars, the steel bars need to be supported, thus requiring a suspended tie beam steel bar support structure for bridge construction in water.

[0003] Chinese Patent CN212612007U discloses a non-grounded support structure for column-type cap beams, belonging to the field of bridge construction technology. It includes a support system comprising a pair of support steel plates. One side of each support steel plate is an arc-shaped steel plate that mates with the steel pipe supporting the cap beam. The support steel plates are located on both sides of the steel pipe. A pair of circular holes are pre-drilled on the steel pipe to facilitate the passage of circular steel bars. The ends of the circular steel bars are threaded. After the circular steel bars pass through the support steel plates, the steel pipe, and the support steel plates in sequence, both ends of the circular steel bars are fixed with nuts. A wedge-shaped unloading frame is fixed to the support steel plates, and a longitudinal beam is fixed to the wedge-shaped unloading frame. The upper end of the longitudinal beam is a crossbeam. This invention solves the technical problem of non-grounded support construction for cap beams, eliminates the technical problem of poor stability with a single pin, and fully utilizes the mechanical properties of materials while ensuring construction safety.

[0004] While the steel bar support structure described above eliminates the technical problem of poor stability of a single pin and fully utilizes the mechanical properties of the material while ensuring construction safety, the steel bar support structure is relatively fixed during use and cannot be fine-tuned according to actual needs, which can easily affect the stability of the support. Therefore, we propose a steel bar support structure for suspended tie beams in bridge construction water. Utility Model Content

[0005] The purpose of this utility model is to provide a suspended tie beam steel bar support structure for bridge construction water, so as to solve the problem mentioned in the background art that the support structure of the steel bar is relatively fixed during use and cannot be finely adjusted according to actual needs, which easily affects the stability of the support.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended tie beam steel bar support structure for bridge construction in water, comprising:

[0007] A hollow steel column, wherein clamping blocks are provided on both sides of the hollow steel column, and fixing screws are installed at the connection between the clamping blocks and the hollow steel column. A lifting plate is connected to one side of the clamping blocks, and a connecting column is installed on the outside of the lifting plate.

[0008] A telescopic column is connected below the connecting column. A support column is connected below the telescopic column. A lifting hydraulic push rod is installed inside the connecting column. A linkage block is connected above the lifting hydraulic push rod. The lifting hydraulic push rod forms a telescopic structure with the lifting plate through the linkage block. The lifting plate is fixedly connected to the clamping block. The clamping blocks are symmetrically distributed about the vertical center line of the hollow steel column.

[0009] A movable seat is installed at both ends of the lifting plate. A supporting inclined rod is connected to one side of the movable seat, and a reinforcing block is connected to one end of the supporting inclined rod. A nut seat is connected to the inner side of the movable seat, and a transmission screw is installed inside the nut seat. A drive motor is connected to one end of the transmission screw.

[0010] Preferably, the connecting column forms a tension structure with the support column through the telescopic column, and the telescopic column and the support column are fixed to each other by bolts.

[0011] Preferably, the drive motor and the lead screw form a rotating structure, and the lead screw passes through the interior of the nut seat, and the nut seat is fixedly connected to the movable seat.

[0012] Preferably, the movable seat is fixedly connected to the reinforcing block via a supporting diagonal rod, and the reinforcing blocks are symmetrically distributed about the vertical center line of the hollow steel column.

[0013] Compared with the prior art, this utility model provides a suspended tie beam steel bar support structure for bridge construction in water, which has the following beneficial effects:

[0014] This invention uses a lifting hydraulic push rod to drive the linkage block and lifting plate to rise and fall, thereby facilitating the adjustment of the support structure to a suitable position on the steel bar. A fixing screw connects the clamping block and the steel bar, and a drive motor drives the transmission screw to rotate. The rotating transmission screw can transmit the nut seat and the moving seat horizontally, thus moving the reinforcing block to a designated position. This avoids the problem that the support structure of the steel bar is relatively fixed during use and cannot be fine-tuned according to actual needs, which can easily affect the stability of the support.

[0023] Working Principle: When using the suspended tie beam steel bar support structure in the water supply for bridge construction, firstly, the hollow steel column 1 is installed in the designated position, and then the support column 7 is installed on the ground at the corresponding position of the hollow steel column 1 and fixed. Then, the connecting column 5 and the support column 7 are stretched together by the telescopic column 6 until the support structure is adjusted to a suitable height.
