Description

Technical Field

[0001] This utility model belongs to the field of prestress testing technology, and specifically relates to an anchor installation device for prestress tensioning. Background Technology

[0002] Prestressing tensioning is a technique that applies tensile force to structural members in advance. Its purpose is to induce deformation in the member before it bears external loads, thereby improving its bending resistance and stiffness, delaying crack initiation, and increasing its durability. Before prestressing tensioning, the reinforcing bars need to be passed through anchorages, and then the anchorages are moved to the anchor plate position. During construction, workers pass each reinforcing bar through the anchorage holes and then repeatedly strike the anchorage with hollow steel pipes to move it towards the anchor plate. This anchorage installation process is time-consuming and labor-intensive, resulting in low installation efficiency. Therefore, we propose an anchorage installation device for prestressing tensioning. Utility Model Content

[0003] The purpose of this utility model is to provide an anchor installation device for prestressed tensioning, which aims to solve the technical problem of low anchor installation efficiency in the prior art mentioned above.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An anchor installation device for prestressed tensioning includes a bracket with a "U"-shaped structure. The bracket includes a top plate, with support columns perpendicularly connected to both sides of the top plate. A fixing plate is provided at the end of each support column. A receiving cavity is provided within each support column, with a first sliding groove on one side. A threaded rod is hinged within the receiving cavity, extending along the length of the support column. A rotating rod at one end of the threaded rod passes through the top plate, and a gear is provided at the end of the rotating rod. A turntable is provided on one side of the top plate, and a stepper motor is provided on the other side. The stepper motor drives the turntable to rotate. A gear ring is fitted onto the turntable, meshing with gears on both sides. A sliding block, threadedly connected to the threaded rod, is fitted onto the threaded rod. The sliding block slides within the receiving cavity. A connecting rod is provided on one side of the sliding block, extending through the first sliding groove. A fixing member is provided at the end of the connecting rod, and the fixing members on both sides cooperate to push the circular anchor.

[0006] Furthermore, the fixing member includes a first arc-shaped plate and a second arc-shaped plate connected vertically. The first arc-shaped plate is used to fit the arc-shaped sidewall of the circular anchor, and the second arc-shaped plate is used to push the circular anchor.

[0007] Furthermore, an electric push rod is provided between the connecting rod and the fixing member, and the telescopic end of the electric push rod is connected to the first arc-shaped plate.

[0008] Furthermore, the electric push rod has a second sliding groove on each side of its outer shell, the second sliding groove slidably connecting the slide rod, and the slide rod is connected to the first arc-shaped plate.

[0009] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0010] 1. This utility model provides an anchor installation device for prestressed tensioning. The bracket is set on the reinforcing bar, the stepper motor drives the turntable to rotate, and the gear ring meshes with the gear to drive the lead screw to rotate. The circular anchor is pushed towards the anchor plate through the sliding seats on both sides, the support rod and the fixing parts. Compared with the installation method of repeatedly impacting the anchor with hollow steel pipe, this anchor installation device has a higher installation efficiency.

[0011] 2. An electric push rod is installed between the connecting rod and the fixing component. The distance between the two fixing components is adjusted by the electric push rod to accommodate round anchors of different sizes. Sliding rods are installed on both sides of the electric push rod to help improve the connection stability between the electric push rod and the fixing component. Attached Figure Description
