Abstract
A roof top stainless steel rail grounding terminal comprises a steel plate and a fixing belt; the steel plate and the fixing belt are fixedly connected; one end of the steel plate is provided with a wiring terminal hole; the fixing belt is divided into two half circles respectively fixed on a left side and a right side of the steel plate; a middle portion of the fixing belt is fixed by a fastening bolt. The advantages are that the wiring terminal hole on one end of the roof top stainless steel rail grounding terminal is connected with a connecting hole on an upper end of a lightning protection belt; the roof top stainless steel rail grounding terminal and the lightning protection belt are fixed by a bolt; the stainless steel rail inserts into the circle of the fixing belt of the steel plate and fixed by the fastening bolt, no welding is needed, thereby providing effective lightning protection; intergranular corrosion is not generated between the stainless steel and carbon steel, so the grounding terminal is beautiful and well fixed.
Description
Technical field
The utility model relates to building material field, is specifically related to a kind of balcony stainless steel railing earth terminal.
Background technology:
Thunder and lightning causes serious threat near people and animals' life security, and building is damaged, forest fire, and oil, electric power, meteorology, communication, Aero-Space Architectural Equipment do great damage.Along lightning current flow direction, make several kilometers of spaces around cause powerful drastic change electromagnetic field, the physical effects such as electrostatic field and intense electromagnetic radiation.Inducing lightning voltage, lightning current passes to every family by supply line, signal line and various metal pipe line and causes casualties, especially microelectronic device (computer, TV, communication equipment, electric equipment etc.) is done great damage, cause heavy economic losses, thundering is the natural phenomena that every year repeats generation.There are design specification, construction specification, acceptance specification in country carry out as mandatory term lightning protection.Due to the more and more primary standard design of people's balcony in architectural design lighting proof strip, major part is made lighting proof strip by the round steel originally designing, and changes stainless steel railing into, and doubles as the lighting proof strip into building.But because stainless steel railing is too thin with stainless steel tube wall, weld mutually with former lighting proof strip round steel, directly butt welding does not meet design specification and acceptance specification, the two-sided welding of 6 times of overlap joints, affects again attractive in appearancely, and stainless steel and carbon steel generation intercrystalline corrosion, be unfavorable for taking shelter from the thunder.When occurring, thunder and lightning easily causes the damage of casualties, equipment.
The material and the application conditions thereof that according to < < Code for design of lightning protection of buildings > > GB 50057-2010 5.1.1 lightning protection devices, use should meet table 5. and 1. 1 prescribed material: stainless steel; Be used in atmosphere: single conductor; Twisted wire; Corrosion-resistant situation: good in many environment; 5.1.2 do the smallest cross-sectional that lightning protection equipotential connects each link and should meet the regulation equipotential connection relay part of showing 5.1.2: the bonding conductor from equipotential connection tape splicing to earthing device or between each equipotential connection tape splicing, material: F e (iron) cross section (m m 2): 50.< < architectural electricity engineering construction quality acceptance specification > > GB50303-2011 24.2.1 is when design no requirement (NR), and the earthing device end face depth of burying should not be less than 0.6m.Round steel, angle steel and steel pipe earth electrode should vertically be imbedded underground, and spacing should not be less than 5m.
The welding of earthing device should adopt overlap welding, and the lap of splice should meet the following requirements:
1 band steel and band steel overlap joint is band steel width 2 times, be no less than three weldings;
2 round steel and round steel overlap joint is round steel diameter 6 times, two-sided welding;
3 round steel and band steel overlap joint is round steel diameter 6 times, two-sided welding;
4 band steels and steel pipe, the welding of band steel and angle steel, is close to two sides outside angle steel, or is close to 3/4 steel tube surface, upper and lower both sides welding;
5 welding point, have anti-corrosion measure in being embedded in concrete.
GB50169-2006 erection works of electrical installations code for construction and asseptance of earthed devices
The connection of 3.4 earth electrodes (line)
3.4.1 the connection of earth electrode (line) should adopt welding, and welding must be firmly without rosin joint.Be connected to the earth connection on electric equipment, application galvanized bolt connects; When non-ferrous metal earth connection can not adopt welding, available bolt connection, crimping, thermit welding (heat release welding) mode connect.While connecting with bolt, should establish jam nut or check washer, bolt junction contact-making surface should be by the predetermined processing of existing national standard < < electric device installing engineering bus device construction and acceptance specification > > GBJ149.Connection between different materials earth electrode should be processed.
Summary of the invention:
The technical problems to be solved in the utility model is that a kind of solution stainless steel railing welds inconvenience mutually with lighting proof strip round steel, though welding good after also easily with the problem of carbon steel generation intercrystalline corrosion, thereby design this balcony stainless steel railing earth terminal.
A kind of balcony stainless steel railing earth terminal, its feature is: this balcony stainless steel railing earth terminal is comprising steel plate, fixed band, described steel plate is fixedly connected with described fixed band, one end of described steel plate is provided with binding post hole, described fixed band is divided into two semicircles, be separately fixed at the left and right sides of steel plate, in the middle of fixed band, adopt to tight a bolt and fixed.
According to above-mentioned a kind of balcony stainless steel railing earth terminal, its feature is: described fixed band can design a plurality of, is arranged on steel plate in order.
The utility model has the advantages that: the binding post hole of balcony stainless steel railing earth terminal one end connects the connecting hole of lighting proof strip upper end, adopt bolt that balcony stainless steel railing earth terminal and lighting proof strip are fixed, stainless steel railing inserts in the annulus of the fixed band on steel plate, by tighting a bolt, fixed, without welding, can effectively take shelter from the thunder, stainless steel and carbon steel do not produce intercrystalline corrosion, not only attractive in appearance but also can well fix.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model is installed and used schematic diagram.
In accompanying drawing
