Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile production, in particular to a pipe mold fixing device for pipe pile tensioning. Background Art

[0002] A pipe pile is a hollow cylindrical concrete member formed by a steel reinforcement cage or axial main reinforcement and concrete in a pipe mold. In the production of pipe piles, the steel reinforcement cage or axial main reinforcement needs to be prestressed and tensioned first. Prestress tensioning means applying a tensile force in advance in the member, so that the prestressed tensioned member bears tensile stress, and then causing it to produce a certain deformation to cope with the loads received by the steel structure itself.

[0003] When the pipe pile is tensioned, the steel reinforcement cage or axial main reinforcement is placed in the pipe mold, and the pipe mold is placed on the workbench. The tensioning machine is arranged at one end of the workbench (pipe mold). The tensioning machine is connected to the steel reinforcement cage or axial main reinforcement through a tensioning plate to achieve tensioning. In the prior art, the fixing of the pipe mold on the workbench is poor, and the pipe mold is prone to shift during the tensioning process, affecting the quality of the pipe pile. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipe mold fixing device for pipe pile tensioning, which can well fix the pipe mold during the tensioning process, has strong stability and is not prone to shift.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pipe mold fixing device for pipe pile tensioning, including a base, a support frame and a support plate. The support frames are arranged on the base and there are multiple of them. The multiple support frames are arranged at intervals along the axis direction of the pipe mold. There are two support plates, and the two support plates are respectively arranged at the two side edges of the multiple support frames. The support plate is provided with a groove Ⅰ for limiting the centrifugal support ring of the pipe mold and a buckle ring for buckling the pipe mold. The two ends of the buckle ring are respectively connected to the two support plates.

[0006] As a preference of this technical solution, a plurality of support seats are correspondingly arranged on the support plate. One end of the buckle ring is rotatably connected to a support seat, and the other end is detachably connected to the corresponding other support seat. The arrangement of the support seats enables the buckle ring to buckle on the upper semi-circle of the pipe mold.

[0007] As a preference of this technical solution, the support plate includes a base plate and a movable plate. The side surface of the base plate facing the other support plate is provided with a groove Ⅱ. The groove Ⅱ is open on three sides, and the groove opening facing the other support plate is bent inward to form a limiting boss. The movable plate is slidably limited in the groove Ⅱ. The groove Ⅰ is arranged on the movable plate. The arrangement of the groove Ⅱ can replace different movable plates for different pipe molds. The positions and sizes of the groove Ⅰ on the movable plate are different for corresponding different pipe molds.

[0008] As an optimization of this technical solution, a fixed plate is arranged outside the substrate. The fixed plate is fixed on the support frame. An expander is arranged on the fixed plate. The output end of the expander is connected to the substrate to drive the substrate to approach or move away from another support plate. The expander is provided to adjust the distance between the two support plates to accommodate different sizes of pipe molds.

[0009] As an optimization of this technical solution, the bottom wall of the groove Ⅰ is inclined with the outer side higher than the inner side, which can better support the pipe mold.

One end of the buckle ring 4 is rotatably connected to a support seat 5 through a hinge, and the other end is connected to another support seat 5 through bolts and nuts. The support seats are provided so that the buckle ring 4 buckles on the upper semi-circle of the tube mold, rather than buckling on the bolts at the connection of the upper mold and the lower mold. The buckle ring 4 is in an arc shape, and the arc shape is adapted to the outer shape of the upper mold of the tube mold. Different buckle rings are replaced corresponding to different sizes of tube molds.
