Description
Technical field
The utility model belongs to electric fixtures security technology area, relates to a kind of lightning protection device of prefabricated frame trestle.
Background technology
For preventing the building that is struck by lightning, current builing industry generally adopts installation lightning protection device, and to meet direct striking thunder prevention, anti-lightning surge invades and the requirement of Lightning Electromagnetic Pulse.
As the ingredient that lightning protection device is important, down lead requires that it should meet mechanical strength, corrosion-resistant and heat-staple requirement.
Usually to utilize in the reinforced concrete column of building or shear wall two elongated longitudinal reinforcements as down lead.But, because the longitudinal reinforcement of prefabricated frame trestle is connected by straight screw sleeve grouting in prefabricated costruction, longitudinal reinforcement in upper and lower prefabricated frame trestle cannot form continuous conductor, therefore the longitudinal reinforcement of prefabricated frame trestle cannot as the metallic conductor of connecting roof arrester and ground device.
Utility model content
The utility model need solve the problems referred to above be in prefabricated costruction in above-mentioned prior art due to the main muscle of prefabricated frame trestle by straight screw sleeve grouting connect, main muscle in upper and lower prefabricated frame trestle cannot form the deficiency of continuous conductor, and provides a kind of lightning protection device being welded into the prefabricated frame trestle of down lead by metallic conductor order.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of lightning protection device of prefabricated frame trestle, comprise the metallic conductor be preset in prefabricated frame trestle, described metallic conductor longitudinally runs through prefabricated frame trestle, upper and lower two adjacent prefabricated frame trestles are fixedly connected with at construction floor place, two neighbouring metallic conductors carry out bending and being welded to each other in construction floor, the upper end of the metallic conductor in the prefabricated frame trestle of top is connected with arrester, and the lower end of the metallic conductor in the prefabricated frame trestle of described lowermost end is connected with ground device.
Described metallic conductor is round steel or band steel.
Described metallic conductor is 40*4 Hot-dip zinc-coated flat steel sheet.
Described metallic conductor is positioned at the edge of prefabricated frame trestle.
The length of stretching out prefabricated frame trestle after described metallic conductor bending is more than or equal to 150mm.
The length that two neighbouring metallic conductors are welded to each other is more than or equal to 50mm.
Compared with prior art, the beneficial effects of the utility model are:
(1) upper and lower two adjacent prefabricated frame trestles are fixedly connected with at construction floor place, two neighbouring metallic conductors carry out bending and being welded to each other in construction floor, thus form the down lead of lightning protection device in prefabricated frame trestle, the upper end of the metallic conductor in the prefabricated frame trestle of top is connected with arrester, the lower end of the metallic conductor in the prefabricated frame trestle of lowermost end is connected with ground device, form lightning protection device, meet direct striking thunder prevention, anti-lightning surge invades and the requirement of Lightning Electromagnetic Pulse.
(2) metallic conductor is round steel or band steel, meets mechanical strength, corrosion-resistant and heat-staple requirement.
(3) overcome the defect affecting outward appearance that in prior art, down lead lays along skin, just can complete in process of construction meanwhile, very convenient, also not easily by artificial damage.
