Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, and relates to a lightning protection bracket for electrical engineering, in particular to a lightning protection bracket which is particularly suitable for steel-concrete structures and has good waterproof effect. Background Art

[0002] Lightning has great destructiveness, with its voltage reaching millions to tens of millions of volts and its current reaching hundreds of thousands of amperes. Lightning strikes can blow up buildings or cause fires, resulting in casualties of people and livestock, and also causing accidents such as power outages in the power system. Therefore, buildings vulnerable to lightning strikes must be equipped with lightning protection devices. During the construction process of electrical engineering, lightning protection brackets are often used. Currently, there are mainly two common lightning protection brackets for electrical engineering: one is fixed on the concrete parapet wall; the other is directly welded on the steel members.

[0003] At present, the gradual expansion of the application of steel-concrete structures has brought some disadvantages to the application of existing lightning protection brackets - there are great problems in waterproof treatment. Specifically, when the steel columns and steel beams of the building adopt steel structures, the roof is a concrete roof, and the exterior wall is a sandwich panel wall. At this time, the waterproofing between the exterior wall and the parapet wall only depends on the parapet wall cover plate. The installation of the lightning protection bracket will damage the integrity of the cover plate, and the later sealing is complex and the waterproof effect is poor.

[0004] Therefore, it is of great practical significance to develop a waterproof and lightning protection bracket that is particularly suitable for steel-concrete structures. Content of the Utility Model

[0005] Due to the above-mentioned defects in the prior art, the utility model provides a waterproof and lightning protection bracket that is particularly suitable for steel-concrete structures, overcoming the defects that the existing lightning protection brackets are difficult to be applicable to steel-concrete structures and have poor waterproof effect.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lightning protection bracket for electrical engineering, comprising an internal and external threaded column embedment, a lightning protection bracket column and a lightning protection wire clamp head;

[0008] The internal and external threaded column embedment includes an internal and external threaded column and a washer I. The internal and external threaded column is a cylindrical structure with threaded structures on the inner and outer walls. The washer I is sleeved outside the internal and external threaded column and is coaxially and fixedly connected with the internal and external threaded column. The end of the internal and external threaded column with the washer I is embedded into the position to be fixed;

[0009] The lightning protection bracket column includes a connecting rod. One end of the connecting rod is provided with an internal threaded hole on the connecting rod coaxial with the connecting rod. The outer wall of the other end of the connecting rod is provided with an external fixed threaded structure matching the internal threaded structure of the internal and external threaded column. After the connecting rod is inserted into the internal and external threaded column, it is threadedly connected with the internal and external threaded column;

[0010] The lightning protection wire clamp includes an arched clamping plate, a flat clamping plate and a lower fixing stud of the clamp. The lower fixing stud of the clamp is vertically fixed to the flat clamping plate and is matched with the internal threaded hole on the connecting rod. After the lower fixing stud of the clamp is inserted into the internal threaded hole on the connecting rod, it is threadedly connected with the internal threaded hole on the connecting rod. The side of the flat clamping plate away from the lower fixing stud of the clamp is fixedly connected with the arched clamping plate through a clamping plate fixing bolt. The external thread structure on the outer wall of the internal and external tooth column is used to increase the contact surface between the internal and external tooth column and the embedded concrete and improve the bonding strength between the internal and external tooth column and the embedded concrete.

[0011] The lightning protection bracket for electrical engineering of the present utility model has a reasonable structural design. The lightning protection bracket is divided into three parts, and each component is fixedly connected by threaded connection. It is convenient to install and the height can be adjusted according to actual needs, with good applicability. The internal and external tooth column embedment is used as an embedded part, and the opening at the position to be fixed is small. Cooperating with gasket I can cover the opening on the parapet cover plate, which can significantly improve the waterproof effect. The above-mentioned bracket is not only applicable to concrete structures, but also applied to pure steel structures that require lightning protection brackets. The internal and external tooth columns can be directly welded to the steel structure, with good applicability and good application prospects.

[0012] As a preferred technical solution:

[0013] For a lightning protection bracket for electrical engineering as described above, a gasket II coaxially fixedly connected with the connecting rod is also sleeved outside the connecting rod. The end of the connecting rod provided with the gasket II is inserted into the internal and external tooth column. The cooperation between the gasket II and the gasket I can further improve the waterproof and sealing effect.

[0014] For a lightning protection bracket for electrical engineering as described above, after the connecting rod is threadedly connected with the internal and external tooth column, the gasket II completely covers the gasket I, that is, the size of the gasket II is slightly larger than that of the gasket I.

[0015] For a lightning protection bracket for electrical engineering as described above, both the gasket I and the gasket II are in a flared structure;

[0016] The gasket I opens towards the embedded end of the internal and external tooth column, and the gasket II opens towards the direction of connection with the internal and external tooth column.

[0017] For a lightning protection bracket for electrical engineering as described above, a nut is also sleeved outside the connecting rod (field operators can use the nut to tighten and loosen the lightning protection bracket column with a wrench, making the operation more convenient), and the nut is fixedly welded to the connecting rod.

[0018] For a lightning protection bracket for electrical engineering as described above, the internal and external tooth column is welded to the gasket I;

[0019] The connecting rod is welded to the gasket II;

[0020] The flat clamping plate is welded to the lower fixing stud of the clamp.

[0021] A lightning protection bracket for electrical engineering as described above, the outer surfaces of the internal and external threaded columns, washer I, connecting rod, washer II, nut, arched splint, flat splint, lower fixing stud of the chuck and clamping plate fixing bolt are all provided with galvanized layers to improve the durability of the components;

[0022] The galvanized layers of washer I and washer II are also provided with PE layers, which can reduce the damage to the parapet cover plate caused by metal friction and prevent rusting.

[0023] The above technical solutions are only one feasible technical solution of the present utility model, and the protection scope of the present utility model is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0024] The above-mentioned utility model has the following advantages or beneficial effects:

[0025] (1) The lightning protection bracket for electrical engineering of the present utility model is convenient for the installation of the parapet cover plate through a three-section design, which is beneficial to the hole opening positioning of the parapet cover plate, reduces the hole opening area at the same time, reduces the damage to the parapet cover plate, and increases the waterproof effect;

[0026] (2) The lightning protection bracket for electrical engineering of the present utility model, through the cooperation of washer I arranged on the internal and external threaded column embedment and washer II on the lightning protection bracket column, can significantly improve the overall waterproof and sealing effect. During the fastening process of the internal and external threaded column embedment and the lightning protection bracket column, the parapet cover plate will arch and deform due to the presence of the washer, thus achieving a waterproof effect. Sealant can be applied at the hole opening to fill the gap between the washers, making the washer area integrally impermeable;

[0027] (3) The lightning protection bracket for electrical engineering of the present utility model, the PE layers on washer I and washer II reduce the damage to the parapet cover plate caused by metal friction, prevent rusting, improve durability, and have good application prospects.
