Process for constructing metal roof of building with super-large space

Abstract

The invention discloses a process for constructing a metal roof of a building with super-large space. The process includes steps of 1), laying a steel lining plate on the lowermost layer of a roof structure; 2), laying a non-woven dustproof layer on the lining plate; 3), laying a glass wool sound absorbing layer on the non-woven dustproof layer and compacting the glass wool sound absorbing layer; 4), laying a vapor barrier on the glass wool sound absorbing layer; 5), laying lower-layer glass wool on the vapor barrier and compacting the lower-layer glass wool; 6), laying upper-layer heat-insulation rock wool on the lower-layer glass wool and compacting the upper-layer heat-insulation rock wool; 7), mounting support purline; 8), laying supporting steel plates; 9), laying a gypsum fiber board; 10), laying a waterproof vapor-permeable layer on the gypsum fiber board; 11), laying an ultrafine glass cotton anti-noise layer on the waterproof vapor-permeable layer; 12), mounting an aluminum-magnesium-manganese alloy roof panel on the uppermost layer of the roof structure. The process for constructing the metal roof has the advantages that a waterproof effect of the metal roof is improved, water seepage at pierced positions is prevented, outdoor noise is prevented from being transmitted into a room, and heat-insulation, damp-proof and vapor-permeable effects of the metal roof are improved.

Description

technical field [0001] The invention relates to a super large space building metal roof. Background technique [0002] For super large space buildings, there are several main problems as follows: [0003] 1. The waterproof level of the roof is high. Once leakage occurs, it will cause huge political impact and economic losses; [0004] 2. As the rain falls on the roof panel, there will be impact sound on the roof panel, and at the same time, due to the action of the wind, there may be wind noise on the roof, or other outdoor noises will eventually be transmitted to the room through the roof layer; [0005] 3. In addition, as we all know, glass wool or rock wool has been widely used as roof / wall insulation materials in modern buildings because of its light weight and good performance. However, if the moisture-proof treatment of the enclosure system is not good, the indoor water vapor will It is easy to penetrate into the enclosure system, making the insulation cotton moldy a...

AI Technical Summary

Problems solved by technology

[0003] 1. The waterproof level of the roof is high. Once leakage occurs, it will cause huge political influence and economic loss;

[0004] 2. As the rain falls on the roof panel, there will be impact sound on the roof panel, and at the same time, due to the action of the wind, there may be wind noise on the roof, or other outdoor noises will eventually be transmitted to the room through the roof layer;

[0005] 3. In addition, as we all know, glass wool or rock wool has been widely used as roof / wall insulation materials in modern buildings because of its light weight and good performance. However, if the moisture-proof treatment of the enclosure system is not good, the indoor water vapor will It is easy to penetrate into the enclosure system, making the insulation cotton moldy and deteriorated, thereby greatly reducing the insulation performance;

[0006] 4. The aluminum alloy support is fixed by self-tapping screws, so the roof is inevitably pierced by self-tapping screws, and there are hundreds of thousands of such holes in the entire metal roof, and the waterproofing of the holes becomes the top priority
