The height of the lightning belt support card is 15-20cm, the spacing is 80-100cm, and the corner is 30cm.
The lightening belt bracket is made of galvanized Angle steel (L25*3) or galvanized flat steel (-25×3) in actual construction, and can be installed with special clips or wire rope clips. The upper mouth of the fixing clip on the support cannot be closed with the Angle steel of the support. The lightning arrester should be straight and flat, and the spacing of the fixed point support parts should be uniform and reliable. Each support part should be able to support the vertical tension of more than 49N (5kg).
The galvanized round steel lightning arrester belt is connected with a single Z lap (it is recommended to use a self-made mold), the lap length is 6 times the diameter of the round steel, and the top and bottom lap. The semicircular plane of the expansion compensation is perpendicular or parallel to the sky plane. The spacing of the lightening belt bracket in the straight section should be evenly divided, and the spacing should be controlled at 0.5-1.5m, and it should generally be determined as 1m.
The lightening belt should be straight and of the same height, and the deviation of flatness should not be greater than 3\/1000 per 2m inspection section.
The height of the lightning belt support card is 15-20cm, the spacing is 80-100cm, and the corner is 30cm. Lightning arrester bracket clamp introduction to direct lightning protection of high-rise buildings emphasizes the basic principle of adhering to the use of open application of lightning connector.
In accordance with the provisions of the specific and clear parts in Appendix II of GB50057-94, the ridge, corner, eaves, corner edges and parapet walls of the building, roof frame, floating plate, roof ladder roof, pool top and other vulnerable parts of the building are all laid with metal lightning connector.
The height of the lightning belt support is 12 ~ 15 cm, the distance between the support is 1 m, and the turning point is 50 cm
The height of the lightening belt bracket is 150mm, the installation height is 10Cm, and the installation distance is not more than 100Cm. Greater than 30Cm at the corner corner.
