Roof color steel plate lap-joint structure and mounting method thereof

Abstract

The invention discloses a roof color steel plate lap-joint structure and a mounting method thereof. The lap-joint structure comprises roof purlines, roof lower plates and roof upper plates, and the roof lower plates and the roof upper plates are all roof color steel plates; reinforced plates are arranged on the top surfaces of the roof purlines, and top segments of the roof lower plates and bottomsegments of the roof upper plates form lap-joint segments on the reinforced plates; among the lap-joint segments, male ribs and female ribs in the roof lower plates and the roof upper plates are cutrespectively, notches are formed, and the roof lower plates and the roof upper plates in the lap-joint segments are attached to each other through interlacing of the notches; multiple waterproof blocks are arranged at the positions, where the notches are formed, on the top segments of the roof lower plates by using waterproof cement gum; the roof upper plates, the roof lower plates and the reinforced plates are fixedly connected from top to bottom by using waterproof self-tapping screws. By adopting the roof color steel plate lap-joint structure, the structure of the cut portions of the super-long roof color steel plates is stable, the cut portions do not collapse, ponding does not exist, and the waterproof effect is guaranteed.

Description

technical field [0001] The invention relates to a lap joint structure of roof color steel plates and an installation method thereof, in particular to lap joints applied to the termination parts of roof color steel plates of large-span steel structure factories and an on-site production and installation method thereof. Background technique [0002] With the rapid development of steel structure buildings, green and environmentally friendly steel structure residences and high-rise steel-concrete structures are increasing. Due to the large span of the large-span steel structure factory building and the length of the whole board reaching more than 30 meters, the roof color steel plate needs to be interrupted for installation, resulting in insufficient waterproofing, and water leakage occurs from time to time. The strength of the overlapping parts is low, resulting in the collapse of the overlapping parts of the roof color steel plate, forming water accumulation and causing large-...

AI Technical Summary

Problems solved by technology

Due to the large span of the large-span steel structure factory building and the length of the whole board reaching more than 30 meters, the roof color steel plate needs to be interrupted for installation, resulting in insufficient waterproofing, and water leakage occurs from time to time. The strength of the overlapping parts is low, causing the overlapping parts of the roof color steel plate to collapse, forming water accumulation and causing large-scale water leakage, which seriously affects production and office
