Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a lightning protection device for the top of a construction hoist. Background Technology

[0002] Currently, residential and commercial buildings are being designed to be increasingly tall. Construction sites of tall buildings often face the risk of lightning strikes during the summer when thunderstorms are frequent, so it is necessary to install lightning protection devices.

[0003] Since the tower cranes were the tallest structures on the construction site at the beginning of construction, lightning rods were installed on their tops. However, after the tower cranes were dismantled, the construction hoist guide rails erected on the outside of the buildings became the tallest metal structure on the entire construction site. Although lightning protection rings were installed on the parapet walls at the top of the buildings, the construction hoist guide rails were still at risk of being struck by lightning because the top of the guide rails was higher than the parapet walls.

[0004] If a lightning rod is installed directly on the top of the construction hoist guide rail, the lightning current will be transmitted through the guide rail bolts and then conducted to the ground through the grounding wire. This process is highly unstable and has low transmission efficiency. If a tall lightning protection grounding device is erected not far from the construction hoist guide rail, the operation will be cumbersome and require a significant increase in manpower and resources. Summary of the Invention

[0005] The purpose of this utility model is to provide a lightning protection device for the top of a construction hoist, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention can adopt the following technical solution:

[0007] The lightning protection device for the top of the construction hoist of this utility model includes a rubber insulating plate fixed to the top wall of the angle steel beam at the top of the construction hoist guide rail frame. One end of the rubber insulating plate extends outward and is provided with a rubber insulating block that is bent down and fixed to the side wall of the angle steel beam. The rubber insulating block has a vertical insertion hole, and a lightning rod is fixedly inserted into the insertion hole. A down conductor is welded to the lightning rod located above the rubber insulating block. The other end of the down conductor is welded to the lightning protection ring on the parapet wall at the top of the building body.

[0008] Furthermore, a first fixing bolt is embedded vertically through the top wall of the angle steel beam within the rubber insulating plate, and a first fastening nut is screwed onto the first fixing bolt; a second fixing bolt is embedded horizontally through the side wall of the angle steel beam within the rubber insulating block, and a second fastening nut is screwed onto the second fixing bolt. This facilitates the fixing of the rubber insulating plate and the rubber insulating block onto the angle steel beam at the top of the construction hoist guide rail frame, and also greatly improves the stability of the rubber insulating plate and the rubber insulating block.

[0009] Furthermore, the lead wire is a galvanized round steel connector with good conductivity and corrosion resistance.

[0010] The advantage of this invention is that the lightning rod is insulated and installed on the angle steel beam at the top of the construction hoist guide rail frame by using rubber insulating boards and rubber insulating blocks. Then, the lightning rod is connected to the lightning protection ring on the parapet wall at the top of the building by using galvanized round steel down conductors. This easily conducts the lightning current to the ground, improves the lightning current conduction rate, avoids lightning damage to equipment, and enhances the practicality and ease of installation of the entire lightning protection device.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0015] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0016] like Figure 1 , 2 As shown, the lightning protection device for the top of the construction hoist of this utility model includes a rubber insulating plate 1, which is fixed to the top wall of the angle steel beam 100 at the top of the guide rail frame of the construction hoist. The end of the rubber insulating plate 1 near the building body extends outward and folds downward to form a rectangular rubber insulating block 2 fixed to the side wall of the angle steel beam 100. The rubber insulating block 2 and the rubber insulating plate 1 are integrally formed.

[0017] A vertical insertion hole 3 is provided on the rubber insulating block 2. The insertion hole 3 can be a through hole or a blind hole. A lightning rod 4 is fixedly inserted in it. The diameter of the rod part of the lightning rod 4 should be slightly larger than the diameter of the insertion hole 3. In this way, the elasticity of the rubber insulating block 2 can clamp the lightning rod 4 inserted into the insertion hole 3, ensuring that the lightning rod 4 can stand stably on the top of the construction hoist guide rail frame.

[0018] In addition, a down conductor 5 is welded to the lightning rod 4 located above the rubber insulating block 2. The down conductor 5 can be made of galvanized round steel formed by bending, which has good conductivity and corrosion resistance. The other end of the down conductor 5 is welded and fixed to the lightning protection ring 6 installed on the parapet wall 200 at the top of the building. Thus, when the lightning rod 4 is struck by lightning, the lightning current will be conducted to the lightning protection ring 6 through the down conductor 5, and then conducted to the ground by the lightning protection ring 6. This greatly improves the lightning current conduction rate, avoids lightning damage to the lifting equipment on the construction hoist guide rail, and improves the practicality and installation convenience of the entire lightning protection device.

[0019] Furthermore, to ensure that the rubber insulation board 1 is more securely attached to the top wall of the angle steel beam 100, a first fixing bolt 7 can be embedded in the rubber insulation board 1. The first fixing bolt 7 extends vertically downward through the bottom wall of the rubber insulation board 1, and a first fastening nut 8 is screwed onto its protruding end. At this time, a first through hole 9 corresponding to the first fixing bolt 7 is opened on the top wall of the angle steel beam 100. Thus, when the rubber insulation board 1 is attached to the top wall of the angle steel beam 100, the first fixing bolt 7 can just pass through the first through hole 9. Then, the first fastening nut 8 is screwed onto the first fixing bolt 7, so that the first fastening nut 8 is firmly attached to the lower surface of the top wall of the angle steel beam 100, forming a fixed connection between the rubber insulation board 1 and the top wall of the angle steel beam 100, which greatly improves the stability of the rubber insulation board 1.

[0020] Similarly, to ensure that the rubber insulating block 2 is more securely attached to the side wall of the angle steel beam 100, a second fixing bolt 10 can be embedded in the rubber insulating block 2. The second fixing bolt 10 extends horizontally out of the rubber insulating block 2 towards the rubber insulating plate 1, and a second fastening nut 11 is screwed onto its protruding end. At this time, a second through hole 12 corresponding to the second fixing bolt 10 is opened on the side wall of the angle steel beam 100. Thus, when the rubber insulating block 2 is attached to the side wall of the angle steel beam 100, the second fixing bolt 10 can just pass through the second through hole 12. Then, the second fastening nut 11 is screwed onto the second fixing bolt 10, so that the second fastening nut 11 is firmly pressed against the inner surface of the side wall of the angle steel beam 100, forming a fixed connection between the rubber insulating block 2 and the side wall of the angle steel beam 100, which greatly improves the stability of the rubber insulating block 2.
