Abstract
The utility model discloses a lightning-protection structure of a building. The building comprises a foundation below the horizon, a grounded counterpoise at the bottom of the foundation, a main building body above the horizon and a lightning-protection unit on the top of the main building body. The outer wall of the main building body is connected with the foundation and the lightning-protection unit. The outer wall, especially, is internally provided with a conductive grounding downlead. One end of the grounding downlead is in conduction connection with the lightning-protection unit, and the other end passes through the foundation and is in conduction connection with the grounded counterpoise. The grounding downlead is externally wrapped with a heat dissipation unit. By applying the lightning-protection structure, the cases of damage and misoperation of electric appliances and electronic systems due to lightning electromagnetic impulse can be reduced, thereby guaranteeing personal safety and property safety; and meanwhile, the grounding downlead is added with the heat dissipation unit, thereby prolonging the service life of a lightning-protection system of the building, and reducing the failure rate of the lightning-protection system.
Description
Technical field
The utility model relates to a kind of lightning protection structure, relates in particular to a kind of lightning protection structure of building.
Background technology
Along with development in science and technology, rapidly, high buildings and large mansions are in a compact mass, lightning strike accident showed increased in building trade development, LEMP also can cause electrical equipment and electronic system is damaged or the problem of error running, and thunderbolt also can produce the serious consequence such as loss of life or personal injury and property loss.
In prior art, building interior has earth connection, and the resistance of earth connection is larger, in lightning-arrest process, usually occurs the phenomenons such as heating, and severe patient, can cause earth connection fusing, makes the lightning protection system paralysis of building, causes the condition of a disaster to occur.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the lightning protection structure that proposes a kind of building.
The purpose of this utility model, to be achieved by the following technical programs: a kind of lightning protection structure of building, building comprise ground below horizon, counterpoises, more than horizon main building body and the lightning-arrest unit at main building body top of basal part, the exterior wall of described main building body is connected with ground, lightning-arrest unit, it is characterized in that: the described outer down conductor that is provided with within the walls conduction, one end of described down conductor is connected with lightning-arrest cell conduction, the other end is connected with counterpoises conducting through ground, and described down conductor is surrounded by heat-sink unit outward.
Further, described heat-sink unit is physics radiating subassembly and/or chemical radiating subassembly.
Further, described lightning protection structure is provided with and is connected to the ground test point of down conductor, underground test point and test point within the walls.
Apply lightning protection structure of the present utility model, can reduce the generation that LEMP causes electrical equipment and electronic system damage or error running, guarantee personal safety and property safety, on down conductor, set up heat-sink unit simultaneously, improve the lightning protection system useful life of building, reduced the failure rate of lightning protection system.
Brief description of the drawings
Fig. 1 is the structural representation of the lightning protection structure of a kind of building of the utility model.
Embodiment
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.
As shown in Figure 1, a kind of lightning protection structure of building, building comprises the ground 1 below horizon, the counterpoises 2 of ground 1 bottom, the lightning-arrest unit 4 at main building body 3 more than horizon and main building body 3 tops, exterior wall 31 and the ground 1 of main building body 3, lightning-arrest unit 4 is connected, especially, in exterior wall 31, be provided with the down conductor 5 of conduction, one end of down conductor 5 is connected with 4 conductings of lightning-arrest unit, the other end is connected with counterpoises 2 conductings through ground 1, in the time that the lightning-arrest unit of generation is subject to being struck by lightning, the electric current of thunder and lightning prolongs down conductor 5 and enters counterpoises 2, can not exert an influence to building interior personnel and electrical equipment etc., and the outer heat-sink unit 6 that is surrounded by of down conductor 5, can lower the temperature to down conductor, the process that prevents lightning current causes down conductor 5 excess Temperatures to cause fusing, reduce the failure rate of the lightning protection system of building, wherein, heat-sink unit 6 is physics radiating subassembly and/or chemical radiating subassembly.
In addition, lightning protection structure is also provided with and is connected to the ground test point of down conductor, underground test point and test point within the walls, when civil engineering, the convenient Construction Condition that detects down conductor, also can be used for the routine testing to building, can monitor the situation of down conductor.
Visible by above description: to apply lightning protection structure of the present utility model, can reduce the generation that LEMP causes electrical equipment and electronic system damage or error running, guarantee personal safety and property safety, on down conductor, set up heat-sink unit simultaneously, improve the lightning protection system useful life of building, reduced the failure rate of lightning protection system.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection range of the present utility model.
