Problems solved by technology

However, after careful analysis, this scheme also has a fly in the ointment. The fasteners are connected by mutual insertion, which requires the pile body to accurately locate the position between each fastener when connecting each other. The connection between the two piles can only be realized when the positions are in one-to-one correspondence. Therefore, the docking process takes a long time to realize

Embodiment 1

[0040] Such as figure 1 As shown, a prefabricated pile with a locking end plate includes a strip-shaped pile body 10, a steel reinforcement cage 11 is arranged inside the pile body 10, and the two ends of the reinforcement cage 11 are thickened to form a pier head 111, so The pile body 10 described includes alternately arranged large section piles 12 and small section piles 13, the cross section shapes of the large section piles 12 and the small section piles 13 can be circular, square or other shapes, and the large section piles 12 and the small section piles The cross-sectional shapes of the piles 13 may be the same or different.

[0041] A locking end plate 20 is respectively fixed at the two ends of the pile body 10. The end of the pile body 10 can be a large-section pile 12 or a small-section pile 13. The shape of the locking end plate 20 is consistent with that of the pile body 10 ends. same shape as Figure 6 As shown, the locking end plate 20 is circular. As shown in...

Embodiment 2

[0053] The structure and connection method of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 2 As shown, the locking groove structure 30 includes a groove 31 provided on the outer wall of the locking end plate 20 . That is, the locking end plate 20 is directly connected to the pile body 10 .

Abstract

The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a prefabricated pile with a locking end plate and a connection method thereof. The variable cross-section pile includes a long strip-shaped pile body, and a steel cage is arranged in the pile body. A locking end plate is respectively fixed at both ends of the pile body. The outer wall of the locking end plate is provided with a locking groove structure. The tight end plate is provided with a plurality of stretching hole structures penetrating through the locking end plate, and the pier head of the steel cage in the pile body can be inserted into the stretching hole structure and blocked by the stretching hole structure. The connection method includes bringing the ends of the two piles close together, inserting locking blocks into the locking groove structures of the locking end plates of the two piles respectively, and the shape and size of the locking blocks inserted into the locking groove structure Compatible with the locking groove structure, screw and lock the locking blocks in the two locking end plates with a pair of locking bolts. The invention has the advantages of fast connection, firmness, easy operation and the like.

Description

technical field [0001] The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a conveniently connected pile and a connecting method thereof, in particular to a prefabricated pile with a locking end plate and a connecting method thereof. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0003] The existing piles are connected by setting metal end plates at both ends of the piles. When two piles need to be connected, they are connected by welding the end plates of the two piles. The welding work is time-consuming and laborious, and the connection is inconvenient , In addition, the weld is easily corroded by the...
