Problems solved by technology
[0005] The property company needs to clean the curtain wall frequently. Because the lightning-terminating belt is higher than the roof, it will often encounter the lightning-terminating belt when installing and moving the hanging basket, hanging plate, and safety rope, causing the lightning-terminating belt and the support frame to bend and shake. If things go on like this, it will Cause the holes on the stone to expand, and water leakage will occur in rainy days

Embodiment Construction
[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0052] A construction technique of stainless steel lightning-terminating strips on stone curtain wall roof, refer to figure 1 , including the following steps:
[0053] S1: Lofting and positioning, the civil engineering personnel will stake out and show the position where the stainless steel angle steel 51 needs to be installed on the roof 1.
[0054] S2: The straight section is prefabricated. The stainless steel air-termination belt adopts 40*4mm 304 stainless steel angle steel 51. Its curvature, side width, side thickness, top angle, theoretical weight and other properties should meet the requirements of the national acceptance standard. The chemical composition of the stainless steel angle steel 51 The content of chromium in the medium is ≥16%, the content of nickel is ≥8%, and the content of carbon is ≤0.08%.
[0055] refer to figure 2 and im...

Abstract
The invention discloses a construction process of a stainless steel flashover belt on the roof of a stone curtain wall, which relates to the technical field of building lightning protection construction and comprises the following steps: S1, setting out and positioning; S2: prefabricating a straight section, connecting several sections of stainless steel angle steel; S3: installing, bonding the prefabricated stainless steel angle steel envelope to the stone curtain wall, overlapping connecting the stainless steel angle steel with the lightning protection down lead, and connecting the lightningprotection down lead with the grounding device; S4: installing the stone sealing plate, connecting the stone sealing plate with the top of the roof, the overlap of the stainless steel angle steel andthe lightning protection downlead, so that the upper surface of the stainless steel angle steel horizontal side and the upper surface of the stone sealing plate are on the same plane. The stainless steel angle steel is installed close to the top of the stone curtain wall and does not pass through the stone sealing plate, the roof is relatively flat, the damage of the stainless steel angle steel caused by external force can be avoided, the leakage phenomenon is avoided, the service life of the stone curtain wall is prolonged, and the existing hidden danger of safety is solved.
Description
technical field [0001] The invention relates to the technical field of building lightning protection construction, more specifically, it relates to a construction technique of a stainless steel lightning-terminating belt on a stone curtain wall and roof. Background technique [0002] With the continuous development of construction projects, stone curtain walls have been widely used in medium and high-end construction projects. In order to prevent or reduce personal injury and property loss caused by lightning strikes on building curtain walls, and to achieve safety, reliability, and economical rationality, it is increasingly important to take good lightning protection measures for building curtain walls. [0003] A complete set of lightning protection devices includes lightning receptors, down conductors and grounding devices. Among them, the lightning receptor is the part used to receive the lightning current, which is in the form of metal components such as lightning rods...
