A kind of multifunctional metal roof and its construction method

Abstract

The invention relates to the technical field of building engineering, in particular to a multifunctional metal roof and a construction method thereof. The multifunctional metal roof made by the construction method comprises a plurality of roof purlins mounted at the top of a building and pressed steel plates fixed to the top of the roof purlins and also comprises leveling steel plates, waterproof coils, a ventilation denoising wire mesh and a plurality of aluminum-magnesium-manganese alloy gussets, the leveling steel plates are fixed to the top of the pressed steel plates, and the waterproof coils are fixed to the top of the leveling steel plates; the aluminum-magnesium-manganese alloy gussets are fixed to the top of the waterproof coils, and the ventilation denoising wire mesh is spread between the waterproof coils and the aluminum-magnesium-manganese alloy gussets. The multifunctional metal roof is better than the traditional planting roofs, water storage roofs and elevated roofs, is lower in overall manufacturing cost and has functions such as waterproofing, denoising, thermal insulation, acoustic insulation and decorating.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a multifunctional metal roof and a construction method thereof. Background technique [0002] The construction of large public buildings, industrial buildings, and flat-to-slope residential projects requires special roof construction. There are three main types of traditional roof construction, the first is planted roofs, the second is water storage roofs, and the third is elevated roofs. Among them, the planted roof uses green plants planted in various culture media to achieve the effect of heat insulation and cooling, but this kind of planted roof needs to be covered with soil, which will increase the weight of the roof and impose requirements on the load-bearing performance of the building. High, the cost of the building will increase accordingly. In addition to the waterproof requirements of the building, the biggest problem of the water storage roof is the...

AI Technical Summary

Problems solved by technology

Among them, the planted roof uses green plants planted in various culture media to achieve the effect of heat insulation and cooling, but this kind of planted roof needs to be covered with soil, which will increase the weight of the roof and impose requirements on the load-bearing performance of the building. high, the cost of the building will increase accordingly

In addition to the waterproof requirements of the building, the biggest problem of the water storage roof is the timely supply of water sources. The deep water storage depth of the water storage roof is generally 500mm, and the shallow water storage depth is generally 200mm. In summer, if the water source cannot be replenished in time, It is easy to cause the water-storage roof to dry up, which will cause the rigid waterproof layer of the building to crack and cannot be repaired; at the same time, the water-storage roof also requires high load-bearing performance of the building, and the cost of the building will increase accordingly

Finally, the overhead roof lowers the temperature of the lower surface of the roof by setting a ventilated air space on the roof to achieve the purpose of heat insulation and cooling, but the noise reduction function of the overhead roof is deteriorated due to the existence of the overhead structure

To sum up, the roofs of buildings in the prior art cannot integrate functions such as waterproofing, noise reduction, heat preservation, heat insulation, sound insulation, and decoration.
