Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a prestressed anchor pipe pile structure. Background Art

[0002] With the rapid development of my country's national economy and the continuous advancement of engineering technology, my country's construction industry has also made great progress. At present, in the construction of construction projects, prestressed concrete pipe piles have the advantages of good crack resistance, fast construction speed, and high pile strength. They are widely used in construction projects. Research on the static load test of prestressed concrete pipe piles has important practical significance.

[0003] After searching, the published patent number CN218667500U mentioned a compressive prestressed anchor pipe pile structure, which includes a pedestal, a reinforcement component and an anti-rust component. The pedestal is plugged with a reinforcement component for strengthening the compressive prestressed anchor pipe pile structure. The reinforcement component includes a prestressed anchor end plate, a pad, steel bars and a reinforcing rib plate. The pedestal is plugged with a prestressed anchor end plate. The top of the prestressed anchor end plate is fixedly provided with a pad and there are four groups of pads. The steel bars pass through the pad and the prestressed anchor end plate and are plugged into the pedestal. The reinforcing rib plate is evenly distributed along the circumference of the inner ring of the pad. The top of the steel bar is plugged into the main body of the pipe pile. The utility model solves the problem of long-term exposure and deformation of steel bars, which cannot ensure the compressive, bending and pull-out resistance of the pipe pile, through the reinforcement component. The anti-rust component prevents the steel bars from rusting and extends the service life of the steel bars.

[0004] Although the above solution solves the problems raised in the background technology, it still has the following shortcomings: when limiting the steel bars, the limiting effect is poor, resulting in poor compression, bending and pull-out resistance, and low practicality.

[0008] The fixing structure includes a connecting rod fixedly connected to the top of the prestressed anchor end plate through a groove, the outer side of the connecting rod is movably connected to a movable frame, and a second spring is provided on the outer side of the connecting rod close to the movable frame.

[0009] As a preferred solution of the present invention, the outer diameter of the steel bar is equal to the inner diameter of the protective sleeve.

[0010] As a preferred solution of the present invention, a fixing groove is provided on the top of the movable frame.

[0011] As a preferred solution of the present invention, a slot is provided on the inner side of the support platform.

[0012] As a preferred solution of the present invention, the number of the protective sleeves is four.

[0013] As a preferred solution of the present invention, the top end of the fixing plate is fixedly connected to a fixing seat adapted to the protective sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the utility model, a splint, a first spring, a prestressed anchor end plate, a fixed structure, a pedestal and a protective sleeve are arranged in a prestressed anchor pipe pile structure, so that the movable frame is pulled through the fixed groove to move along the connecting rod, and the second spring is deformed under the force. The steel bar is limited by the cooperation of the splint, the first spring, the prestressed anchor end plate, the pedestal and the protective sleeve, thereby improving the compression resistance, bending resistance and pull-out resistance and enhancing the practicality.
