The support bar 5 is galvanized steel bar straight-bar, and support bar one end is welded and fixed with angle steel, and the other end is welded and fixed through the cover plate 6 above parapet and curtain wall and the cambered middle part of support card 2 vertically upward along parapet side and plays a part of additional reinforcement support card；The cover plate 6 is 30mm thickness granite slabstones.After the cover plate installs, cover plate gap, cover plate hole are needed to be blocked with fluid sealant, it is ensured that water-tight.
The lighting proof strip 3 is galvanized steel bar, lighting proof strip suspension frame is above curtain wall top, and welded with some support card front ends, lighting proof strip is connected with one end of lighting proof strip ground lead 9, the other end connection roof lightning grid 10 of lighting proof strip ground lead, the lighting proof strip device of the anti-sideflash of roofing skeleton layer curtain wall is consequently formed, wherein：All a diameter of 12mm of galvanized steel bar：The welded lap length of all galvanized steel bars and galvanized steel bar is not less than 12 times of galvanized steel bar diameters：All weld weld seams should be full, must not there is slag inclusion, crackle, gas hole defect, and postwelding weld seam should brushing antirust paint.
Embodiment 2
The lighting proof strip distribution method of the anti-sideflash of roofing skeleton layer stone curtain wall of the present invention, suitable for two level Lightning Protection Building, reinforced concrete roof is taken shelter from the thunder belt supporting frame and secretly deposited lighting proof strip forms by surface, in lightning-arrest grid of the roofing composition no more than 10m*10m or 12m*8m.Earthing or grounding means is formed using building reinforcement foundation and artificial earth electrode, and building lightning protection measures are set by code requirement.Bright dress lighting proof strip makees bright dress lighting proof strip using the galvanized steel bars of φ 12, along the horizontal laying such as top between roofing eave, ladder, support level spacing 1.0m, corner 0.5m, one of aluminium paint of red lead two is applied in weld after installing.The tie point of lighting proof strip and arrester is middle reliably to be welded with steel grid in each floor plate using two diagonal reinforcing bars of φ 16mm in building reinforced column, lower end and the main reinforcement welding of two, foundation beam bottom, upper end and roof lightning welding.Grounding resistance is not more than 0.5 ohm.The lighting proof strip distribution method construction process of the anti-sideflash of roofing skeleton layer stone curtain wall of the present invention is：It is familiar with drawing → materials arrival inspection → cooperation and reserves → unwrapping wire pinpoints → welding Auxiliary support angle steel → welding auxiliary support bar → fixation support card → parapet upper cover plate and take hole → lightning conduction installation → correction inspection → cover plate holes blocking → paint brushing → mark.
It is that lightning current is introduced to the passage of the earth in order to prevent thunderbolt from destroying building that the roof lightning band of the present invention, which is set, not only wants well conducting, and reliable and stable.The roof lightning band of the present invention is to connect to form lightning conduction as support card, then with φ 12mm galvanized steel bars by being extended to the cambered φ 12mm galvanized steel bars in wall side in beam.
The lighting proof strip distribution method of the anti-sideflash of roofing skeleton layer stone curtain wall of the present invention specifically includes following steps：
A, lightning protection earthing lead is reserved
In civil engineering parapet of roofing, galvanized steel bar in the reinforcing bar and parapet of each lightning protection downlead of building is welded, form roof lightning grid and drawn out of parapet, as the ground lead of roof lightning band, length must is fulfilled for the connection request of later stage lighting proof strip；
B, the welding of support bar angle steel
Using L40*40*4 angle steel as fixing point below support bar, angle steel is close to parapet side, and both ends are welded on curtain wall embedded iron parts or curtain wall square steel keel and antirust mopping processing is done to welding position；
C, lighting proof strip support card is fixed
Roof lightning band is fixed in support card, support card is that wall side is extended to from parapet into radian, due to spanning half of parapet, curtain skeleton installing space and stone curtain wall thickness, so that the round steel span of radian is larger, less stable, in order to ensure the stability of lighting proof strip, the auxiliary support bar of support card is additionally arranged；50mm in parapet is squeezed into support card one end, and the other end welds with lighting proof strip galvanized steel bar, middle by aiding in Rod Bracing bar, the requirement of monolithic stability sexual satisfaction；
D, cover plate takes hole and closure
Due to above parapet and curtain wall using 30mm thickness granite as bearing down on one, therefore before being welded after lighting proof strip support card and auxiliary support bar, lay the cover plate that bears down on one cover plate is carried out taking hole.Cover plate takes Kong Qianxian to measure the lighting proof strip support card and Auxiliary support distance that are welded, then arranges brick according to the specification of brick, determines hole, takes hole, hole size only needs that φ 12mm galvanized steel bars can be passed through.After installing cover plate, cover plate gap, cover plate hole are needed to be blocked with fluid sealant, it is ensured that water-tight.
E, lightning conduction is installed
Lighting proof strip uses φ 12mm galvanized steel bars, is welded in support card front end.Because lighting proof strip laying is often very long, the lap of splice of galvanized steel bar and galvanized steel bar is not less than 12 times of galvanized steel bar diameters, lighting proof strip welds the same lap of splice with ground lead and is not less than 12 times of galvanized steel bar diameters, weld weld seam is answered full and has enough mechanical strengths, there must not be the defects of slag inclusion, crackle, stomata, postwelding need to knock out coating and do antirust mopping processing.
The present invention has substantive distinguishing features and significant technological progress, the lighting proof strip distribution method of the anti-sideflash of roofing skeleton layer stone curtain wall of the present invention, make to be arranged at the lighting proof strip of parapet of roofing and frame girder to cover curtain wall edge lightning protection effect, lighting proof strip support card spans half of parapet, curtain skeleton installing space and stone curtain wall thickness and into radian, so that support card and whole lighting proof strip less stable, in order to solve lighting proof strip support card fixation problem, it is additionally arranged the auxiliary support bar of support card, it is ensured that the stability of whole overhanging lighting proof strip.
By earth resistance, lighting proof strip grounding connection is good, and supervisory station, the favorable comment of quality association have also been obtained in terms of high grade project quality examination so that the support of overhanging lighting proof strip is fixed into for bright spot at one.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or change.Therefore, all equivalent technical schemes should also belong to scope of the invention, should be limited by each claim.
