Metal roof structure

Abstract

The invention discloses a metal roof structure. A steel lining plate is arranged on the bottommost layer of the roof structure, an aluminum-magnesium-manganese alloy roof panel is arranged on the topmost layer of the roof structure, a support steel plate and a gypsum fiber plate are arranged between the aluminum-magnesium-manganese alloy roof panel and the lining plate, the support steel plate is supported at the bottom of the gypsum fiber plate, a superfine glass cotton noise proofing layer is filled between the aluminum-magnesium-manganese alloy roof panel and the gypsum fiber plate, support purlines are arranged at the bottom of the support steel plate, a non-woven fabric dustproof layer is paved on the lining plate, a glass cotton sound-absorbing layer is arranged on the non-woven dustproof layer, heat-preserving cotton is filled among the glass cotton sound-absorbing layer and the support purlines, a vapor barrier layer is arranged between the heat preservation cotton and the glass cotton sound-absorbing layer, and a water-proofing and vapor-permeating layer is arranged between the superfine glass cotton noise proofing layer and the gypsum fiber plate. Waterproof effect of a metal roof is improved, outdoor noise is prevented from being transmitted into a room, and a heat preserving, a damp proofing effect and a vapor permeating of the metal roof are improved.

Description

technical field [0001] This invention relates to metal roof structures. 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 and deteriorated, ...
