Problems solved by technology

Although the traditional technology can make the connection of prefabricated piles firm, this pile connection method is not only complicated in connection and operation, but also the prefabricated piles connected in this way have poor seismic performance. Since the prefabricated piles are fixedly connected, when vibration occurs , due to mechanical force, it is easy to cause the connection part of the prefabricated pile to break or the upper and lower section piles to be dislocated and separated

Embodiment 1

[0018] Such as figure 1 As shown, a concrete prefabricated pile joint with an anti-seismic groove, two square pile joints are provided with an end plate 6, and an anti-seismic groove 1 is arranged on the end plate 6 of each prefabricated pile joint, and the anti-seismic groove 1 is arranged on In the center of the prefabricated pile, the anti-seismic grooves on the joint surfaces of the two square piles correspond; image 3 shown. Since the anti-seismic slots of the two butted prefabricated piles correspond exactly to each other, the connecting bolts are placed in the anti-seismic slots, leaving a gap between the connecting bolts and the anti-seismic slots.

[0019] The anti-seismic groove is processed together with the prefabricated pile during the production of the prefabricated pile. In the preset position of the anti-seismic groove, the steel pipe of the required size is directly placed. When pouring concrete, the steel pipe will not be poured with concrete. Therefore, th...

Embodiment 2

[0022] Such as Figure 4 As shown, a concrete prefabricated pile joint with anti-seismic grooves, two prefabricated pile joints are provided with end plates 6, and four anti-seismic grooves 1 are arranged on the end plates 6 of each prefabricated pile joint, and the anti-seismic grooves 1 are all The anti-seismic grooves are distributed on the prefabricated piles, and the center of the anti-seismic groove is on the circle centered on the center of the prefabricated piles. The anti-seismic grooves on the joints of the two square piles correspond to each other; Connecting bolt 4 is arranged. Since the anti-seismic slots of the two butted prefabricated piles correspond exactly to each other, the connecting bolts are placed in the anti-seismic slots, leaving a gap between the connecting bolts and the anti-seismic slots.

[0023] The anti-seismic groove is processed together with the prefabricated pile during the production of the prefabricated pile. In the preset position of the ...

Abstract

The invention discloses a joint with anti-seismic slots for precast concrete piles, belonging to the building field. Two precast pile jointing faces of the joint with anti-seismic slots for precast concrete piles (which can be square or circular and solid or hollow) are both provided with end plates, at least one anti-seismic slot is arranged on the end plate of each precast pile jointing face, and the anti-seismic slots on the two precast pile jointing faces correspond to each other. When two precast piles are connected, connecting steel bolts are arranged in the anti-seismic slots. When the joint with anti-seismic slots for precast concrete piles is in use, after the connecting steel bolts are installed in the anti-seismic slots arranged on the jointing faces, staggered displacement between an upper precast pile and a lower precast pile and pile falling which are generated under the situations of seism and the like can be solved, pile breaking and pile falling can be avoided after a welded junction on the precast pile jointing faces is broken, the upper pile and the lower pile are concentrically stressed, and the main building can be protected from being damaged due to foundation disturbance. Meanwhile, by applying the precast pile joint, the traditional precast pile joint connection mode is changed, steel is saved, and the pile jointing process is also simplified.

Description

technical field [0001] The invention relates to the construction field, in particular to a concrete prefabricated pile joint with an anti-seismic groove. Background technique [0002] As various types of prefabricated piles in foundation pile engineering, most of them need to be connected to piles according to the needs of the project. In the traditional pile-connecting process, an end plate and skirt plate, ie, a steel cap, are arranged at the end of the prefabricated pile, and the pile-connecting is to weld the steel caps of two prefabricated piles, or add a welding connection block outside. Although the traditional technology can make the connection of prefabricated piles firm, this pile connection method is not only complicated in connection and operation, but also the prefabricated piles connected in this way have poor seismic performance. Since the prefabricated piles are fixedly connected, when vibration occurs , Due to mechanical force, it is easy to cause the conne...
