Description

Technical Field

[0001] The utility model relates to the technical field of pile caps, and more specifically, to a prefabricated concrete square pile cap. Background Art

[0002] Concrete square piles are a type of pile foundation component commonly used in foundation engineering. Concrete square piles can withstand horizontal and vertical loads by penetrating deep into the soil layer, providing stable foundation support. During pile foundation construction, concrete square piles need to be driven into the ground. In order to prevent the pile head of the concrete square pile from being damaged, a pile cap needs to be installed on the pile head.

[0003] When precast concrete square pile caps are in use, most of them are directly put on the pile head. However, the inside of some pile caps is not the same size as the outer wall of the square pile, resulting in a certain gap between the inner wall of the pile cap and the outer wall of the square pile, which reduces the protective effect and adaptability of the pile cap. At the same time, after the pile cap is put on the pile head, it lacks the buffering effect against the impact of heavy objects, which reduces the protective effect of the pile cap on the pile head.

[0030] In this embodiment, when the pile cap body 1 is installed, the pile cap body 1 is sleeved on the pile head of the square pile, and the moving hand wheel 8 is rotated. The moving hand wheel 8 drives a moving sleeve 5 to rotate, and through the transmission effect of the moving gear 6 and the transmission gear 7, all the moving sleeves 5 are driven to rotate synchronously. Through the rotation effect of the moving sleeve 5 and the moving screw 4, the moving plate 3 is clamped and fixed to the square pile, and the clamping stability of the moving plate 3 is improved by the anti-skid pad 16. The thread bite force between the moving sleeve 5 and the moving screw 4 is improved by the moving spring 15, thereby improving the supporting stability of the moving plate 3. When a heavy object falls on the top of the square pile, the heavy object hits the support plate 11 and the support block 10, and the impact force is dispersed and buffered by the support spring 12. The support block 10 drives the sliding block 13 to move in the sliding groove 14, limiting the moving direction and position of the support block 10, and at the same time cooperates with the protective pad 17 in the rectangular sleeve 2 to improve the protective effect of the pile cap body 1 on the square pile.

[0031] See also Figure 5 As an implementation method of the fixing block 18: a plurality of fixing blocks 18 are provided at the bottom of the rectangular sleeve 2, an adjusting screw 19 is provided at the bottom of the rectangular sleeve 2, an adjusting sleeve 20 cooperating with the adjusting screw 19 is provided inside the fixing block 18, an adjusting rod 21 is provided at the bottom of the rectangular sleeve 2, an adjusting groove 22 cooperating with the adjusting rod 21 is provided inside the fixing block 18, and an adjusting nut 23 is provided on the adjusting screw 19.

The fixing block 18 is prevented from rotating through the cooperation of the adjusting rod 21 and the adjusting groove 22, and the fixing block 18 is pressed against the ground to support the pile cap body 1, so that the supporting and protective height of the pile cap body 1 can be adjusted according to the extended length of the square pile.

[0033] In summary, when the overall equipment is in use or running: when the pile cap body 1 is installed, the pile cap body 1 is sleeved on the pile head of the square pile, and the moving handwheel 8 is rotated, the moving handwheel 8 drives a moving sleeve 5 to rotate, and through the transmission action of the moving gear 6 and the transmission gear 7, all the moving sleeves 5 are driven to rotate synchronously, and the moving sleeve 5 and the moving screw 4 are rotated to clamp and fix the moving plate 3 to the square pile, and the anti-slip pad 16 is used to improve the clamping stability of the moving plate 3, and the thread bite force between the moving sleeve 5 and the moving screw 4 is improved by the moving spring 15, thereby improving the supporting stability of the moving plate 3. When a heavy object falls on the top of the square pile, the heavy object hits the support plate 11 and the support block 10, and the impact force is dispersed and buffered by the support spring 12, and the support block 10 drives the sliding block 13 to move in the sliding groove 14, limiting the moving direction and position of the support block 10, and at the same time, cooperates with the protective pad 17 in the rectangular sleeve 2 to improve the protective effect of the pile cap body 1 on the square pile.

[0034] When installing the pile cap body 1 again, the adjusting nut 23 is rotated, and the adjusting nut 23 drives the adjusting screw 19 to rotate. The adjusting screw 19 and the adjusting sleeve 20 rotate relative to each other, driving the fixing block 18 to move downward. The fixing block 18 is prevented from rotating through the cooperation of the adjusting rod 21 and the adjusting groove 22, and the fixing block 18 is pressed against the ground to support the pile cap body 1, so that the supporting and protective height of the pile cap body 1 can be adjusted according to the extended length of the square pile.

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
