Technical Field

[0001] The utility model relates to the field of square pile connectors, in particular to a prestressed concrete solid square pile connector. Background Art

[0002] Prefabricated piles are piles made of various materials and in various forms in factories or construction sites. They are driven, pressed or sunk into the soil using pile driving equipment. They are characterized by being able to withstand large loads, being strong and durable, and having a fast construction speed, but having a greater impact on the surrounding environment. The construction procedure is prefabrication, transportation, stacking, and pile sinking. When using solid concrete square piles, a pile connector is required to extend them.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a prestressed concrete solid square pile connector comprises a first connecting member 1, a second connecting member 2 is arranged on one side of the first connecting member 1, a mounting structure 3 is installed at the rear end of the first connecting member 1, the mounting structure 3 comprises four assembling rods 4, a fixing box 6 is installed at the front end of the first connecting member 1, a fastening screw rod 7 is arranged inside the fixing box 6, and a fastening plate 8 is installed at the output end of the fastening screw rod 7.

[0024] In this embodiment, two sides of the fastening plate 8 are in contact with two side inner walls of the first connecting member 1 .

[0025] When the fastening plate 8 is in contact with the inner walls on both sides of the first connecting member 1 , the fastening plate 8 can be ensured to move smoothly.

[0026] In this embodiment, four circular holes are formed at the front end of the second connecting member 2 , the output end of the assembly rod 4 passes through the circular holes and a nut 5 is threadedly installed on the outer wall.

[0027] The round hole facilitates the insertion of the rear end of the assembly rod 4 , and the nut 5 is used to tighten the assembly rod 4 .

[0028] In this embodiment, a limiting structure 10 is provided on one side of the first connecting member 1, and the limiting structure 10 includes a limiting plate 11. A limiting screw rod 12 is provided on one side of the second connecting member 2, and one side of the limiting screw rod 12 is rotatably connected to one side of the limiting plate 11.

[0029] The limiting plate 11 is used to push and limit one side of the pile, and the limiting screw rod 12 is used to adjust the position of the limiting plate 11.

[0030] In this embodiment, the rear end of the limiting plate 11 is in contact with the rear end inner wall of the second connecting member 2 , and a handle 15 is fixedly mounted on one side of the limiting screw rod 12 .

[0031] The handle 15 is used to facilitate the operator to easily rotate the limit screw rod 12.

[0032] In this embodiment, a hidden box 13 is installed inside the second connecting member 2 , a telescopic rod 14 is installed on the inner wall of the hidden box 13 , and one end of the telescopic rod 14 is fixedly connected to the limiting plate 11 .
