Description

Technical Field

[0001] The utility model belongs to the field of precast pile end plates, and particularly relates to a connection structure for precast circular pile end plates. Background Art

[0002] The precast circular pile end plate is a key material used in pile foundation projects. During the construction process, the pile head is often easily damaged, resulting in a reduction in the bearing capacity of the pile. Using the precast circular pile end plate can effectively protect the pile head and extend the service life of the pile. The precast circular pile end plate is mainly used to connect the end of the precast pile and the main reinforcement or other pile segments. When docking with other pile segments, the end plate is often required to achieve the docking. In the existing welding docking method, there are some defects, such as:

[0003] 1. The strength of welding may be inferior to that of mechanical connection, which may affect the construction quality and engineering stability to a certain extent. The connection of precast piles requires good bending resistance, shear resistance, and torsional resistance, while welding may not meet these requirements in some aspects.

[0004] 2. The special properties such as the large diameter and length of precast piles greatly increase the difficulty of welding, and high welding techniques and experience are required. Otherwise, the welding quality cannot be effectively guaranteed.

[0005] 3. During the welding process, if the two circular piles are not aligned, it will be more troublesome to readjust the position. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a connection structure for precast circular pile end plates to solve the problems of inconvenient operation and difficult alignment in the existing pile body docking method.

[0007] The technical solution of the utility model is: a connection structure for precast circular pile end plates, including two sections of pile bodies. The opposite ends of the two sections of pile bodies are respectively provided with annular end plates. One end of the end plate is provided with a connecting sleeve, and the pile body is arranged in the connecting sleeve. The outer wall of the connecting sleeve is provided with a docking component. The docking component includes a mutually cooperating docking groove and a docking block. The docking groove and the docking block are arranged adjacent to each other. One end of the docking block close to the docking groove is provided with a rivet hole. The docking component is provided with an even number of groups and is arranged in central symmetry.

[0008] Further, a pouring channel is opened at the other end of the end plate. The pouring channel is arranged in a circular ring shape along the end face of the end plate. The edge of one end of the connecting sleeve close to the end plate is provided with a merging groove, and the merging groove is communicated with the pouring channel. When the two end plates face each other, the merging grooves are combined. An insertion block is inserted into the combined merging groove, and a pouring hole is opened on the insertion block.

[0009] The beneficial effects of the utility model are:

[0010] 1. In the utility model, the pile body is connected to the end plate through a connecting sleeve. When the pile bodies are butted, the two end plates are opposite to each other. By rotating, the butting block on one connecting sleeve is clamped into the butting groove on the other connecting sleeve. After being completely clamped, the positions of the rivet holes on the butting blocks of the two connecting sleeves are opposite. Then, connecting rivets are used for fixation, and thus the butting of the pile bodies is completed. Through the cooperative connection of the butting components, the alignment positioning and butting fixation of the pile bodies can be quickly completed, with convenient operation and high construction quality.

[0011] 2. In the utility model, a pouring channel is arranged on the end face of the end plate. After the two end plates are butted, the merging grooves are combined, and an inserting block is inserted. Concrete is poured into the pouring channel through the pouring holes on the inserting block. After the concrete solidifies, the fixation between the end plates will be more stable.

[0016] The following will describe the utility model in detail with reference to the drawings.

[0017] As Figures 1-3 shown, a precast circular pile end plate connection structure includes two sections of pile bodies 1. Annular end plates 201 are respectively arranged at the opposite ends of the two sections of pile bodies 1. A plurality of steel bar sockets 5 are arranged on the end plates 201. One end of the end plate 201 is provided with a connecting sleeve 202. The pile body 1 is arranged inside the connecting sleeve 202. The outer wall of the connecting sleeve 202 is provided with a butting component. The butting component includes a butting groove 203 and a butting block 204 that cooperate with each other. The butting groove 203 and the butting block 204 are arranged adjacent to each other. One end of the butting block 204 close to the butting groove 203 is provided with a rivet hole 205. The butting components are provided in an even number and are arranged in central symmetry.

[0018] On the other end of the end plate 201, a pouring channel 302 is provided. The pouring channel 302 is arranged in an annular shape along the end face of the end plate 201. At the edge of one end of the connecting sleeve 202 close to the end plate 201, a merging groove 301 is provided. The merging groove 301 is communicated with the pouring channel 302. When the two end plates 201 face each other, the merging grooves 301 coincide. An insertion block 303 is inserted into the coincided merging grooves 301, and a pouring hole 304 is provided on the insertion block 303.

[0019] Embodiment 1

[0020] In this embodiment, there are 2 groups of docking components and 2 merging grooves 301 on each end plate 201. The merging groove 301 is in a T shape, and when the two merging grooves 301 coincide, they form a cross shape, and the insertion block 303 is in a cross shape.

[0021] When docking two pile bodies 1, the end plates 201 are fixed to the ends of the pile bodies 1 through the connecting sleeves 202 and welded. The end plates 201 on the two pile bodies 1 are made to face each other, and then one of the pile bodies 1 is rotated so that the docking blocks 204 on the two end plates 201 rotate and snap into each other's docking grooves 203. After snapping in place, the positions of the pouring holes 304 of the docking blocks 204 on the two end plates 201 are aligned, and rivets 4 are installed therein for fixation. At this time, the merging grooves 301 on the two end plates 201 coincide, the insertion block 303 is inserted therein, and concrete is poured into the pouring holes 304. The concrete flows into the pouring channel 302 through the merging grooves 301. After the concrete solidifies, the two end plates 201 and the insertion block 302 are connected as a whole, making the two end plates 201 tightly connected, and the appearance of the connecting sleeve 202 is complete and beautiful.

[0022] Compared with the welding docking method, the utility model increases the convenience of pile body docking, is convenient for adjusting the position during docking, and can achieve rapid alignment.
