Metal roof of building with super-large space

Abstract

The invention discloses a metal roof of a building with super-large space. The metal roof is characterized in that an ultrafine glass cotton anti-noise layer is filled between an aluminum-magnesium-manganese alloy roof panel and a gypsum fiber board, support purline is arranged at the bottom of supporting steel plates and supports the supporting steel plates, a non-woven dustproof layer is laid on a lining plate, a glass wool sound absorbing layer is arranged on the non-woven dustproof layer, heat-insulation cotton is filled between the glass wool sound absorbing layer and the support purline, a vapor barrier is arranged between the heat-insulation cotton and the glass wool sound absorbing layer, and a waterproof vapor-permeable layer is arranged between the ultrafine glass cotton anti-noise layer and the gypsum fiber board; the waterproof vapor-permeable layer is compressed by aluminum alloy supports, the aluminum alloy supports are fixed onto the supporting steel plates under the aluminum alloy supports by self-tapping screws, heat-insulation cushions are laid under the bottom surfaces of the aluminum alloy supports, and butyl rubber tapes are arranged among the heat-insulation cushions and the waterproof vapor-permeable layer. 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
