Description

Technical Field

[0001] This application relates to the field of grounding technology, and in particular to a grounding lead-out installation device pre-embedded in a vertical component. Background Technology

[0002] Currently, grounding lead-out installation devices are typically required in facilities such as factories and residential buildings to facilitate quick connection of equipment to the grounding wire. Traditional grounding lead-out installation devices often leave the grounding lead conductor exposed outside the building, which not only affects aesthetics but also fails to adequately protect the grounding lead point, causing inconvenience for subsequent equipment grounding. Furthermore, it poses a safety hazard of pedestrians tripping over it.

[0003] Especially when installing grounding lead-out installation devices for vertical components, it is difficult to control the installation accuracy of the grounding lead-out installation device to ensure that the surface of the grounding terminal is just flush with the surface of the vertical component. If the grounding terminal is recessed inside the vertical component or protrudes outside the surface of the vertical component, there are problems such as failure to ground properly, affecting aesthetics, failure to protect the grounding lead-out point, and creating safety hazards.

[0004] Therefore, there is a need for a grounding lead-out installation device that can make the surface of the grounding terminal flush with the surface of the vertical member. Utility Model Content

[0005] Therefore, it is necessary to provide a grounding lead-out installation device pre-embedded in vertical components, and its specific technical solution is as follows.

[0006] A grounding lead-out installation device pre-embedded in a vertical structural member, comprising:

[0007] A sleeve is pre-embedded in a vertical component; one end of the sleeve has an opening facing the surface of the vertical component;

[0008] The movable part is movably installed inside the sleeve along the axial direction of the sleeve;

[0009] An elastic element has one end connected to the bottom of the sleeve and the other end connected to the movable element; the elastic element has elastic potential energy that drives the movable element to move in the direction of the opening.

[0010] The grounding terminal is connected to the end of the moving part that faces the opening.

[0011] Furthermore, a transition piece is provided between the grounding terminal and the movable part; the transition piece is connected to the grounding lead of the grounding grid.

[0013] Furthermore, one end face of the opening of the sleeve is located inside the vertical member.

[0014] Furthermore, the end face of the grounding terminal is located on the outside of the sleeve, so that a gap is formed between the grounding terminal and the sleeve.

[0015] Furthermore, during the casting of the vertical component, the end face of the grounding terminal abuts against the casting template; after the vertical component is cast, the end face of the grounding terminal is flush with the surface of the vertical component.

[0016] Furthermore, a limiting plate is connected to the movable part, and a limiting element is provided inside the sleeve; after the limiting element abuts against the limiting plate, it restricts the movable part from continuing to move in the direction of the opening.

[0017] Furthermore, a pre-embedded grout sheet is provided on the side of the grounding terminal near the sleeve.

[0018] Furthermore, the grounding terminal has an internal threaded hole on the side away from the sleeve, which is used to connect with the crimping screw.

[0037] Example

[0038] Reference Figure 1 and Figure 2 As shown, this embodiment provides a grounding lead-out installation device pre-embedded in a vertical component, including a sleeve 1, a movable part 2, an elastic part 3, and a grounding terminal 4. It should be noted that, in order to better illustrate the structure of each component, [details omitted]. Figure 2 and Figure 3 The parts have been rendered with a transparent effect.

[0039] The sleeve 1 is embedded in the vertical component. In this embodiment, the vertical component includes, but is not limited to, walls or columns, and can be either precast or cast-in-place. When embedding the sleeve 1, it can be welded or tied to the reinforcing steel structure of the vertical component. One end of the sleeve 1 has an opening 11 facing the surface of the vertical component. One end face of the opening 11 of the sleeve 1 is located inside the vertical component, ensuring that the end face of the opening 11 of the sleeve 1 is not exposed to the surface or exterior of the vertical component.

[0040] The movable component 2 is movably installed inside the sleeve 1 along the axial direction of the sleeve 1. When the sleeve 1 is pre-embedded, the opening 11 faces the surface of the vertical component, so that the axis of the sleeve 1 is arranged horizontally.

[0041] One end of the elastic element 3 is connected to the bottom of the sleeve 1, and the other end is connected to the movable element 2. The elastic element 3 has elastic potential energy that drives the movable element 2 to move in the direction of the opening 11. The grounding terminal 4 is connected to the end of the movable element 2 facing the opening 11. In this embodiment, the elastic element 3 can be a spring. Under the action of the elastic potential energy of the elastic element 3, the grounding terminal 4 can be driven to move towards the outside of the sleeve 1, so that the surface of the grounding terminal 4 abuts against the casting template 6, thereby ensuring that the surface of the grounding terminal 4 is flush with the surface of the vertical member. After the casting is completed, the vertical member wraps around the grounding terminal 4, thereby fixing the grounding terminal 4 in a fixed state.

[0042] The grounding lead-out installation device embedded in the vertical component provided in this embodiment, before pouring, pushes the movable part 2 towards the direction of the opening 11 of the sleeve 1 under the action of the elastic part 3, so that the surface of the grounding terminal 4 abuts against the pouring template 6, thereby making the surface of the grounding terminal 4 flush with the surface of the poured vertical component, avoiding the problem of the grounding terminal 4 protruding or sinking, ensuring the aesthetics of the surface of the vertical component, avoiding the impact of the aesthetics of the surface of the vertical component due to the protrusion of the grounding terminal 4, and also avoiding the inability to ground normally due to the sinking of the grounding terminal 4.

[0043] Specifically, continue to refer to Figure 2 As shown, a connector 5 is also provided between the grounding terminal 4 and the movable part 2; the connector 5 is connected to the grounding lead-out line 7 of the grounding grid. The connector 5 is made of copper, which connects the grounding terminal 4 to the grounding lead-out line 7 of the grounding grid, thereby achieving grounding. The connector 5 is a T-shaped copper tube, with its first end 51 connected to the grounding terminal 4, its second end 52 connected to the movable part 2, and its third end 53 connected to the grounding lead-out line 7 of the grounding grid. A sliding groove 12 extending along the axis of the sleeve 1 is provided on the side wall of the sleeve 1, and the third end 53 of the T-shaped copper tube passes through the sliding groove 12. When the elastic member 3 pushes the movable part 2 to move, the third end 53 of the T-shaped copper tube slides within the sliding groove 12.

[0044] Specifically, the end face of the grounding terminal 4 is located on the outside of the sleeve 1, creating a gap between the grounding terminal 4 and the sleeve 1. This gap allows concrete to enter the sleeve 1 during pouring, thus better securing the grounding terminal 4 and ensuring the stability of the connection between the grounding terminal 4 and the wall. Under the action of the elastic element 3, the size of this gap can be increased or decreased according to the size of the pouring template 6.

[0045] Specifically, during the casting of the vertical component, the end face of the grounding terminal 4 abuts against the casting template 6; after the vertical component is cast, the end face of the grounding terminal 4 is flush with the surface of the vertical component. During casting, the end face of the grounding terminal 4 abuts against the casting template 6 under the action of the elastic element 3, thereby ensuring that the end face of the grounding terminal 4 is flush with the surface of the vertical component after casting.

[0046] Specifically, continue to refer to Figure 2 As shown, a limiting plate 21 is connected to the movable part 2, and a limiting member 13 is provided inside the sleeve 1. After the limiting member 13 abuts against the limiting plate 21, it restricts the movable part 2 from continuing to move in the direction of the opening 11. In this embodiment, the sleeve 1 can be made of PVC pipe, and the limiting plate 21 can be made of a circular plate, so that the outer contour of the limiting plate 21 fits the inner contour of the sleeve 1, thereby ensuring that the movable part 2 is always stably centered. The limiting member 13 can be made of screw, which is inserted into the sleeve 1 through the sleeve 1 to block the limiting plate 21. The maximum stroke of the movable part 2 is limited by setting the limiting plate 21 and the limiting member 13.

[0047] Specifically, the grounding terminal 4 is provided with a pre-embedded grout plate 41 on the side near the sleeve 1. There are two pre-embedded grout plates 41, which are arranged opposite to each other. By setting the pre-embedded grout plates 41, the torsional resistance is improved after the concrete hardens, making the connection between the grounding terminal 4 and the vertical component more stable.

[0048] Reference Figure 3 As shown, the grounding terminal 4 has an internal threaded hole 42 on the side away from the sleeve 1. The internal threaded hole 42 is used to connect with the crimping screw 9. To better illustrate the internal threaded hole 42, when the equipment needs to be grounded, the crimping screw 9 is installed in the internal threaded hole 42 to fix the grounding terminal of the equipment.

[0049] Specifically, continue to refer to Figure 2As shown, during the pouring of the vertical component, a mortar-proof baffle 8 is provided between the end face of the grounding terminal 4 and the pouring template 6; an insert 81 is provided on one side of the mortar-proof baffle 8, and the insert 81 is inserted into the internal threaded hole 42. By setting the insert 81, concrete is prevented from entering the internal threaded hole 42 during pouring, thus avoiding affecting the subsequent normal grounding.

[0050] Installation Process: Before pouring, the sleeve 1 is fixed to the reinforcing steel inside the vertical member, which can be done by binding or welding. When setting up the pouring template 6, the grounding terminal 4, under the elastic potential energy of the elastic element 3, causes its end face to abut against the surface of the pouring template 6, thereby automatically adjusting the position of the grounding terminal 4. It should be noted that, in order to minimize the intrusion of concrete into the internal threaded hole 42 of the grounding terminal 4 during pouring, a mortar-proof baffle 8 can be installed between the grounding terminal 4 and the pouring template 6. During pouring, concrete enters the sleeve 1 through the gap between the grounding terminal 4 and the sleeve 1, thereby fixing the grounding terminal 4 inside the vertical member. When grounding the equipment, the mortar-proof baffle 8 is removed, and the grounding end of the equipment is fixed to the grounding terminal 4 using the crimping screw 9.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
