Technical Field

The invention relates to the technical field of civil and architectural engineering, in particular to a metal roof structure assembly.

Background

According to the latest JGJT 473-. Before the standard is released, the metal roof system is mainly waterproof by a metal plate and is assisted by a waterproof cushion layer, so that the waterproof and moistureproof problems of the metal roof system are solved. However, the weather resistance of the waterproof cushion layer is poor, the dependence of construction quality on human factors is too high, so that the leakage problem of a plurality of projects occurs, the waterproof requirement of the metal roof system is also improved, and new troubles, namely the problems of dewing prevention and fire prevention, are brought to the roof system.

The metal maintenance system has poor air tightness and is easy to generate condensation phenomenon in the interlayer of the metal plate. The polymer waterproof roll is airtight, and if the polymer waterproof roll is arranged above the heat-preservation cotton, water vapor in the interlayer cannot be discharged and dewing is carried out on the lower surface of the waterproof roll, so that the heat-preservation cotton is damaged. After the heat insulation cotton is invalid, the building loses the heat insulation capability, and the energy consumption is terrorist.

Since 2011, except for the waterproof cushion layer and the waterproof coiled material, other materials in the metal maintenance system are A-grade non-combustible materials. The raw materials of the common waterproof coiled material and the waterproof cushion layer are petrochemical products and are all inflammable substances, so that national standards cannot force the waterproof coiled material to reach A grade, but every year, some projects are provided, and fire is generated.

The invention aims to solve the problems of fire catching and condensation of a metal maintenance system caused by a metal roof structural assembly.

After the heat insulation cotton loses effectiveness, the building loses the heat insulation capability, and the energy consumption is very serious. Based on this, according to the metal roof structure assembly provided by the technical scheme, two layers of glass fibers are selected as main protective materials, and the characteristics of the metal roof structure assembly are utilized to ensure the high strength and the high weather resistance of the coiled material, so that the tensile strength of the coiled material can reach more than 1000N/50mm, and the metal roof structure assembly is not influenced by high and low temperature environments. The core material is a fire-resistant non-porous waterproof breathable membrane material so as to realize the waterproof and breathable effects of the coiled material.

In addition, the static water pressure of the novel waterproof coiled material can reach 0.3 MPa required by the waterproof coiled material. The pressure-sensitive adhesive is arranged on the single side of the coiled material, so that the construction is simple and rapid. After the material is compounded, the combustion performance reaches A2 level.
