[0001] The utility model belongs to the field of precast concrete piles, and in particular relates to a precast square pile end plate connection structure. Background Art
[0002] Precast concrete piles are widely used in the fields of construction and water conservancy support. Generally, end plates are set at both ends of precast concrete piles. The functions of the end plates are threefold: first, to prevent the pile hammer from directly acting on the concrete pile body during pile driving; second, to facilitate the connection of the upper and lower sections of the pile body by welding the end plates; third, when preparing the piles, the prestressed steel bars of the steel cage are connected and tensioned through the end plates to form prestress.
[0003] Existing patents propose installing limiting angle irons at the four corners of the end plate body to improve the installation stability of the end plate body on the square pile. However, the height of the limiting angle irons is greater than the thickness of the end plate body, causing the limiting angle irons to protrude from the end plate body, resulting in an uneven surface and the end plate body cannot be stacked, which affects the ease of handling of the end plate body.
[0004] Therefore, in order to solve the above problems, a prefabricated square pile end plate connection structure is proposed. Utility Model Content

[0008] As a further improvement of the present invention, the opposite surfaces of the two limiting angle irons are respectively provided with limiting plates, and the width of the limiting plates is greater than the width of the upper and lower end openings of the movable groove.

[0010] As a further improvement of the present invention, the threaded rod is mounted on the right-angle base via a bearing.
[0011] The beneficial effects of the present utility model are as follows: the present utility model is provided with a limiting angle iron that can be telescopically moved in the groove, and the position of the right-angle base can be adjusted by rotating the threaded rod.

[0018] The present invention will be described in detail below with reference to the accompanying drawings.
[0019] like Figure 1-5As shown, a prefabricated square pile end plate connection structure includes an end plate body 1, and pads 13 are respectively provided on the upper and lower surfaces of the end plate body 1. Grooves 11 are opened at the four corners of the end plate body 1, and the grooves 11 are L-shaped. A connecting mechanism 2 is movably connected in the groove 11; the connecting mechanism 2 is L-shaped, and the connecting mechanism 2 includes a right-angle base 21 and two limiting angle irons 29. A threaded rod 26 is rotatably connected at the right angle of the right-angle base 21, and the threaded rod 26 is connected to the right angle of the groove 11 through a thread. A movable groove 23 is provided in the right angle base 21, which runs through the upper and lower parts. The two limiting angle irons 29 are located in the movable groove 23 and are arranged up and down. A spring 25 is provided between the two limiting angle irons 29. The top of the upper limiting angle iron 29 abuts against the upper pad 13, and the bottom of the lower limiting angle iron 29 abuts against the lower pad 13.
[0020] Spring slots 28 are formed on opposite sides of the two limiting angle irons 29 , and the springs 25 are arranged in the spring slots 28 corresponding to the two limiting angle irons 29 .
[0021] The opposite surfaces of the two limiting angle irons 29 are respectively provided with limiting plates 24 , and the width of the limiting plates 24 is greater than the width of the upper and lower openings of the movable slot 23 .
[0022] The inner side walls of the two right-angled sides of the right-angled base 21 are respectively provided with guide rods 22 , and the inner side walls of the two right-angled sides of the groove 11 are respectively provided with guide grooves 12 . The guide rods 22 are slidably arranged in the guide grooves 12 in a one-to-one correspondence.
[0023] The threaded rod 26 is mounted on the right-angle base 21 through a bearing.
[0024] The position of the right-angle base 21 in the groove 11 can be adjusted by rotating the threaded rod 26. During transportation, the limiting angle iron 29 is pressed into the movable groove 23 and the position of the right-angle base 21 is adjusted by the threaded rod 26, so that the right-angle base 21 is stored in the groove 11, and the upper and lower limiting angle irons 29 are respectively against the surfaces of the upper and lower pads 13, and the two limiting angle irons 29 are clamped between the two pads 13, so that the appearance of the device is flat, easy to stack and transport, and stable to store. During construction, the position of the right-angle base 21 is adjusted by the threaded rod 26, so that the right-angle base 21 moves to the outside of the groove 11. When the limiting angle iron 29 is located outside the pad 13, the pad 27 releases the limit on the limiting angle iron 29. The limiting angle iron 29 can then extend from the movable groove 23 under the elastic action of the spring 25 and protrude from the surface of the pad 13, thereby realizing its limiting function.
[0025] The positions of the right-angle base 21 and the limiting angle iron 29 can be adjusted according to the actual size of the square pile, so that the limiting angle iron 29 can be fitted to the square pile, thereby increasing the firmness and greatly improving the construction quality.
[0026] During the movement of the right-angle base 21, the guide rod 22 slides in the guide groove 12 to guide the movement of the right-angle base 21. The limiting plate 24 limits the movement of the limiting angle iron 29 to prevent the limiting angle iron 29 from falling out of the movable groove 23.
