Description

Technical Field

[0001] The utility model relates to the technical field of concrete hollow square piles, in particular to a reinforced prestressed concrete 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, and are widely used.

[0003] Some of the corners of today's hollow square piles are easily damaged by impact during transportation due to their small force-bearing area. At the same time, after the installation of the hollow square piles, the hollow groove is exposed to the outside, and rainwater, soil and other debris can easily enter the hollow groove, resulting in the need for staff to clean the hollow groove when small steel bars are needed for subsequent core pouring. However, this increases labor costs and reduces work efficiency.

[0004] Therefore, we made improvements and proposed reinforced prestressed concrete hollow square piles. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0011] As a preferred technical solution of the utility model, the upper end surface of the pile body is fitted with the bottom end surface of the first mounting block, and the bottom end surface of the pile body is fitted with the upper end surface of the second mounting block.

[0012] As a preferred technical solution of the utility model, the reinforcing strip and the pile head are both made of steel, and the surfaces of the reinforcing strip and the pile head are provided with an anti-corrosion layer.

[0013] As a preferred technical solution of the utility model, the size of the hollow groove is equal to the size of the groove.

[0014] As a preferred technical solution of the utility model, one side of the clamping block is a beveled surface.

[0015] The beneficial effects of the utility model are:

[0016] 1. Through the use of the installation block 2 and the pile head, when the pile driver drives the pile body, the pile body generates a downward thrust on the installation block 2, and the installation block 2 generates a downward thrust on the pile head.

[0028] Among them, a compression spring 503 is installed on one side of the slide slot 5, and the other end of the compression spring 503 is connected to one side of the limit block 501. The compression spring 503 generates a thrust on the block 502 through the limit block 501, pushing the block 502 into the slot 302.

[0029] A handle 402 is installed on the upper end surface of the baffle 4, and the handle 402 facilitates the movement of the baffle 4.

[0030] Among them, a connecting rod 601 is installed at the bottom end of the mounting block 2 6, and a thread is provided on the surface of the connecting rod 601. The upper end surface of the pile head 7 is provided with a mounting groove 701 matching the thread on the surface of the connecting rod 601. The matching of the connecting rod 601 and the mounting groove 701 facilitates the installation of the pile head 7.

[0031] The sizes of the clamping block 502 and the clamping slot 302 are adapted to each other, and the blocking block 401 can be fixed by the cooperation between the clamping block 502 and the clamping slot 302 .

[0032] Among them, the upper end surface of the pile body 1 is in contact with the bottom end surface of the mounting block 1 3 , and the bottom end surface of the pile body 1 is in contact with the upper end surface of the mounting block 2 6 .

[0033] Among them, the reinforcing strip 2 and the pile head 7 are both made of steel, and the surfaces of the reinforcing strip 2 and the pile head 7 are provided with an anti-corrosion layer. The reinforcing strip 2 protects the corners of the pile body 1 and can also reinforce the pile body 1.

[0034] The size of the hollow groove 101 is equal to the size of the groove 301 .

[0035] One side of the block 502 is a beveled surface.

[0036] Working principle: when the pile driver is driving the pile body 1, the pile body 1 generates a downward thrust on the mounting block 2 6, and the mounting block 2 6 generates a downward thrust on the pile head 7. When encountering a harder ground, since the pile head 7 is conical and made of steel, the pile body 1 can be quickly inserted into the ground. After the pile body 1 is inserted into the ground, the baffle plate 4 is first moved by the handle 402 to push a pair of blocks 502 into the slide groove 5, and then the blocking block 401 is inserted into the groove 301. The baffle plate 4 is rotated by the handle 402, and the baffle plate 4 drives the blocking block 401 to rotate. When the blocks 502 on both sides of the blocking block 401 move to the position of the slot 302, under the action of the compression spring 503, the compression spring 503 is passed through The limit block 501 pushes the card block 502 into the card slot 302, so that the blocking block 401 can be fixed, thereby preventing rainwater, soil and other debris from entering the hollow groove 101, and further avoiding the need for staff to clean the hollow groove 101 when small steel bars need to be placed in the core later. When the blocking block 401 needs to be removed, the baffle plate 4 is rotated by the handle 402, and the baffle plate 4 drives the blocking block 401 to rotate. Since one side of the card block 502 is a beveled surface, when the blocking block 401 rotates, the card block 502 can be pushed into the slide groove 5, and then the baffle plate 4 is moved upward by the handle 402, and the baffle plate 4 drives the blocking block 401 to move upward, so that the blocking block 401 can be quickly removed.
