Description

Technical Field

[0001] The utility model relates to the technical field of hollow square piles, in particular to an earthquake-resistant hollow square pile. Background Art

[0002] Hollow square piles, also known as prestressed square piles, are hollow cylindrical slender concrete precast components made using the prestressing technology and centrifugal forming method. They are mainly composed of a square pile body, end plates and steel hoops.

[0003] The most vulnerable part of hollow square piles is the connection between two hollow square piles. Traditional hollow square piles are mainly connected by welding, but welding is only done on the surface. Once an earthquake occurs, the welding point is prone to breakage, affecting the safety quality of the building.

[0004] Therefore, we made improvements and proposed earthquake-resistant hollow square piles. Utility Model Content

[0007] As a preferred technical solution of the utility model, a pile head is installed at the bottom end of the lower pile.

[0008] As a preferred technical solution of the utility model, a compression spring is installed on one side of the slide slot, and the other end of the compression spring is connected to one side of the limit block.

[0009] As a preferred technical solution of the utility model, the thread on the surface of the bolt is matched with the thread on the inner wall of the thread groove.

[0010] As a preferred technical solution of the utility model, the number of the card slots is equal to that of the card blocks, and the sizes of the card slots and the card blocks are matched.

[0011] As a preferred technical solution of the utility model, the size of the connecting block is adapted to that of the connecting groove.

[0012] The beneficial effects of the utility model are:

[0013] 1. Through the use of the compression spring, the card block, the card slot and the spiral rib, first push the card block outside the circular block at the bottom of the spiral rib into the slide slot, and put the spiral rib into the mounting groove on the surface of the lower mounting block. When the card block moves to the position of the card slot, under the action of the compression spring, the compression spring pushes the card block into the card slot through the limit block, so that the bottom end of the spiral rib can be fixed in the mounting groove on the surface of the lower mounting block. Then push the card block outside the circular block at the top of the spiral rib into the slide slot, and install the upper pile at the top of the lower pile. At this time, the top of the spiral rib enters the mounting groove on the surface of the upper mounting block, and when the card block outside the circular block at the top of the spiral rib moves to the position of the card slot, the compression spring pushes the card block into the card slot through the limit block, so that the top end of the spiral rib can be fixed in the mounting groove on the surface of the upper mounting block. The spiral rib can improve the bearing capacity and seismic performance between the upper pile and the lower pile, and ensure the safety and reliability of the building.

[0014] 2. Through the coordinated use of the connecting block, the connecting groove, the locking bolt and the threaded groove, when the upper pile is installed on the top of the lower pile, the connecting block is also inserted into the connecting groove, and then the locking bolt is screwed into the threaded groove by a tool, so that the connecting block can be fixed, and then the connection between the upper pile and the lower pile can be strengthened, thereby increasing the seismic resistance.
