Upright lockrand roof system and construction method thereof

Abstract

The invention relates to a vertical lockrand roof system. The vertical lockrand roof system comprises a plurality of supports vertically arranged on a net rack. The house lower-layer purline structureis fixedly arranged on the support and is close to the net rack. The bottom plate is laid on the purline structure of the lower floor of the house. The vapor barrier film is laid on the bottom plate.The first heat preservation layer is laid on the vapor barrier film. The first waterproof layer is laid on the first heat preservation layer. The roof upper-layer purline structure is fixedly arranged on the support, and a gap is reserved between the bottom end of the roof upper-layer purline structure and the first waterproof layer. wherein the cavity layer is formed between the bottom end of the roof upper-layer purline structure and the first waterproof layer, and the second waterproof layer is laid on the roof upper-layer purline structure. The roof plate is paved and mounted on the second waterproof layer. The first heat preservation layer is prevented from being damaged by water vapor through the first waterproof layer and the vapor-proof film, the heat preservation layer is well protected, the heat preservation effect of the roof is enhanced through the first heat preservation layer and the cavity layer, and the waterproof and seepage-proof effects of the roof are enhanced through the vapor-proof layer, the first waterproof layer and the second waterproof layer.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a standing seam roof system and a construction method thereof. Background technique [0002] The standing seam roof system is often used in the roof system of public buildings such as airport terminals and large stadiums. There are still many defects in the waterproofing in the prior art, and rainwater or snowwater easily penetrates into the roof from the joint gap between the roof panels, causing water leakage. Especially in the winter heating period, when the indoor temperature is high and the outdoor temperature is low, the water molecules in the air diffuse from indoor to outdoor into the roof under the action of steam pressure, thereby destroying the roof insulation layer, reducing the roof insulation effect, and easily causing indoor water leakage. . Therefore, the heat preservation and waterproofing of the roof system are two major problems. If not handled properly, it...
