Description

Pre-buried formula ground structure Technical Field The application relates to the technical field of lightning protection grounding, in particular to a pre-buried grounding structure. Background Currently, in facilities such as factory buildings, living buildings, etc., it is often necessary to arrange a grounding structure in order to facilitate quick connection of equipment to a grounding line. The traditional grounding structure exposes the grounding lead-out conductor outside the building, thereby not only affecting the beauty, but also leading-out points of the grounding lead-out conductor can not be well protected, thereby bringing inconvenience to the grounding of later-stage equipment, and further having potential safety hazards of tripping pedestrians. For example, the patent of CN207149717U discloses a wall concealed grounding terminal box and an antistatic grounding terminal box, which, although the shell is embedded in the wall, the grounding terminal, i.e. the grounding lead-out conductor, is exposed outside the wall and protected by the connecting terminal cap, however, the grounding terminal exposed outside the wall can make the surface of the wall uneven, affect the beauty, and also cannot fully protect the grounding terminal exposed outside the shell, and is easy to collide with moving personnel or equipment, thus having potential safety hazard. Disclosure of utility model Based on this, it is necessary to provide a pre-buried grounding structure, and the specific technical scheme is as follows. A pre-buried grounding structure, comprising: the embedded part comprises a sleeve and a leveling plate, wherein the leveling plate is connected to the end part of the sleeve; The grounding terminal comprises a terminal body and an end plate connected to the end part of the terminal body, wherein the terminal body is provided with a grounding hole for connecting with external equipment; the base plate is propped against the supporting ear plate and is provided with a through hole for accommodating the terminal body to pass through; the base plate is connected with the base plate, the base plate and the base plate clamp the end plate, the base plate is provided with an exposure hole exposing the grounding hole, and the height of the base plate does not exceed the outer surface of the leveling plate. Specifically, the sleeve is pre-buried in the building, the leveling board is parallel and level with the building surface. Specifically, the side of sleeve is equipped with the cardboard, the cardboard extends outward the sleeve along the radial direction of sleeve. Specifically, the end face of the sleeve is provided with a bearing part, a step is formed between the bearing part and the leveling plate, and the pressing plate is pressed on the bearing part. Specifically, the device also comprises a cover plate, wherein the cover plate covers the pressing plate. Specifically, the outer diameter of the pressing plate is smaller than the inner diameter of the leveling plate, so that an annular gap is formed between the pressing plate and the leveling plate, the cover plate comprises a top plate and a coaming, the top plate covers the pressing plate, and the coaming is inserted into the annular gap. Specifically, the platen is bolted to the carrier. Specifically, the backing plate is connected with the pressing plate through a first connecting bolt, and the supporting ear plate is provided with a positioning hole for accommodating the first connecting bolt to pass through. Specifically, a limiting plate is arranged between the terminal body and the end plate, and a limiting groove for accommodating the limiting plate to pass through is formed in the base plate. Specifically, the grounding hole is a threaded hole. The embedded type grounding structure has the beneficial effects that the leveling plate is leveled with the surface of a building when the embedded type grounding structure is embedded, the grounding terminal is positioned in the embedded part and is connected with equipment to be grounded outside through the grounding hole, so that no bulge exists on the surface of the building, the appearance of the surface of the building is ensured, meanwhile, the collision between the grounding terminal and movable personnel or equipment is avoided, the potential safety hazard is eliminated, in addition, the grounding terminal is completely positioned in the embedded part, and meanwhile, the grounding terminal is comprehensively protected.
