Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried ground piles, in particular to a pre-buried ground pile with a connection structure. Background Art

[0002] Pre-buried ground piles are components used to connect the ground superstructure to the land. They are currently widely used in the foundation support of photovoltaic brackets to increase the stability of photovoltaic brackets. There are many types of existing pre-buried ground piles, among which the most commonly used is the spiral ground pile. Personnel can use a rotary pile driver to assemble the top flange of the spiral ground pile, and drive the spiral ground pile into the ground by rotating and pressing it downward.

[0003] At present, welding is mostly used to assemble and connect metal structural parts on the ground with embedded spiral piles. After use, the piles and the upper structure can only be separated by cutting, which will cause certain damage to the flange parts on the top of the piles, greatly affecting the secondary recycling of the embedded spirals.

[0004] Existing pre-buried piles have the following drawbacks: there is a lack of a connection structure that can replace the direct welding between the upper structure and the pile body to avoid the problem that the pre-buried spiral is damaged and cannot be reused. To this end, we propose a pre-buried pile with a connection structure. Summary of the invention

[0005] The main purpose of the utility model is to provide a pre-buried pile with a connection structure, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A pre-buried ground pile with a connection structure comprises a spiral ground pile, a connection port and a threaded plug-in column, and also comprises a flange and a metal welding block for replacing the upper metal component directly welded to the flange. The flange is welded to the top of the spiral ground pile, and the center of the flange and the spiral ground pile are provided with a connection port, a threaded plug-in column is inserted in the connection port, and the top of the threaded plug-in column is welded to the metal welding block.

[0008] Furthermore, a rod hole is opened on one side of the metal welding block, and the rod hole is equipped with a metal insertion rod.

[0009] Furthermore, the outer diameter of the metal plug rod is consistent with the inner diameter of the rod hole.

[0010] Furthermore, an internal thread corresponding to the threaded plug-in column is provided at the top of the connection port.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Through the assembly consisting of a spiral ground pile, a connection port, a threaded plug-in column, a flange and a metal welding block, a spiral ground pile with a connection structure is provided for personnel. Through the setting of the metal welding block, a welding connection component of an upper metal structure can be provided for personnel. When facing upper metal frame components on the ground such as photovoltaic brackets, personnel can weld the metal components required to be assembled on the upper layer to the top of the metal welding block to avoid welding and fixing between the upper metal components and the spiral ground pile. Therefore, after use, personnel can keep the spiral ground pile as it is, so that the flange will not affect the assembly with the rotary head of the rotary pile driver used for piling during the secondary use, thereby ensuring the sustainable and cyclic utilization of the spiral ground pile, and the metal welding block can be separated from the upper metal component by cutting, and the damage caused by cutting on the surface of the metal welding block will not affect the secondary welding connection between the upper metal component and the metal welding block.

[0013] 2. The metal welding block is used to provide a good connection structure between the spiral pile and the upper metal structure, thereby solving the problem that the spiral pile cannot be reassembled with the rotary pile driver due to the direct welding connection between the spiral pile and the superstructure, and the spiral pile cannot be recycled.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a pre-buried ground pile with a connection structure includes a spiral ground pile 1, a connection port 3 and a threaded plug-in column 6, and also includes a flange 2 and a metal welding block 5 for replacing the upper metal component directly welded to the flange 2. The flange 2 is welded to the top of the spiral ground pile 1, and the center of the flange 2 and the spiral ground pile 1 are both provided with a connection port 3, and a threaded plug-in column 6 is inserted in the connection port 3. The top of the threaded plug-in column 6 is welded to the metal welding block 5.

[0021] A rod hole 7 is provided on one side of the metal welding block 5, and a metal plug rod 8 is provided on the rod hole 7. The outer diameter of the metal plug rod 8 is consistent with the inner diameter of the rod hole 7. Figure 3-4 As shown, a person inserts a metal insert rod 8 into the rod hole 7 to turn the knob of the metal welding block 5 .

[0022] The top of the connection port 3 is provided with an internal thread 4 corresponding to the threaded plug-in column 6; Figure 2-4 As shown, the internal thread 4 allows the threaded plug-in column 6 to be threadedly inserted.

[0023] It should be noted that the utility model is a pre-buried ground pile with a connection structure. When working, the personnel vertically place the spiral ground pile 1 on the land where the pile needs to be piled, and bolt the flange 2 through the spinning head of the pile driving machine to be used. The spiral ground pile 1 is driven into the land at the corresponding position in sequence by spinning. After the spiral ground pile 1 is completely driven into the ground, the personnel inserts the threaded plug column 6 into the connecting port 3, and uses the internal thread 4 to twist the threaded plug column 6 into the connecting port 3. When turning the knob, the personnel inserts the metal plug rod 8 into the rod hole 7 of the metal welding block 5, and then rotates the metal welding block 5 through the metal plug rod 8 to spirally assemble the threaded plug column 6 into the connecting port 3. The connection is formed, and then the personnel place the upper metal frame components such as photovoltaic brackets that need to be fixedly assembled on the ground on the metal welding blocks 5 at the corresponding positions in turn, and then weld the metal frame components to the metal welding blocks 5 by hot welding, so that the personnel can achieve fixed support for the upper components through the metal welding blocks 5 based on the connection between the threaded plug-in column 6 and the spiral ground pile 1. When the upper components need to be dismantled later, the personnel use a cutting machine to cut and separate the upper components from the metal welding blocks 5, and then remove the metal welding blocks 5 from the spiral ground pile 1, so that the spiral ground pile 1 can remain intact, and will not affect the secondary assembly and spinning operation of the spiral ground pile 1 by the spiral pile driver, so that the spiral ground pile 1 can be recycled.
