Water-proof heat-preserving metal roof system

Abstract

The invention discloses a water-proof heat-preserving metal roof system. In the conventional common metal roof system structure, a decorative plate only plays a role in decorating and has a poor water-proof effect. The water-proof heat-preserving metal roof system consists of a decorative plate (25), a primary keel (20), a secondary keel (21), a shoe, a purlin (2) and a lower steel structure (1); the primary keel (20) and the secondary keel (21) intersect in a longitudinal and transverse way; the decorative plate is fixed on a connecting piece; the other end of the connecting piece is fixed on the keels; the primary keel is fixed on the purlin through an adjusting support piece; a steel plate layer is pressed on the purlin; a water-proof layer (10), a protective layer (91), a heat-preserving layer (8) and an air isolating layer (7) are formed on the steel plate layer from top to bottom; a purlin support (3) is used for supporting the purlin (2) on the lower steel structure (1); and a roof upper layer decorative plate (25) is an aluminum-plastic plate or an aluminum veneer or a honeycomb aluminum plate or a titanium-zinc plate or a copper plate. The water-proof heat-preserving metal roof system is applied to water-proof and heat-preserving metal roofs.

Description

technical field [0001] The invention relates to the engineering technical field of a metal roof of a construction project, in particular to a waterproof and heat-preserving metal roof. Background technique [0002] In the current commonly used metal roof system structure, more and more metal decorative panels are used for the surface layer, and the decorative panels only play a decorative role or some also play a certain waterproof role, but the effect is not very good. The roof waterproof mainly depends on The lower waterproof system is also mainly based on metal roof panels. For hyperbolic roofs, the laying of metal roof panels is very difficult. Moreover, the connection between the metal roof panel and the upper decorative panel cannot be effectively and reliably. In cold regions, the snow accumulation is in the early spring, and it is easy to form snow dams. Because the snow dam prevents the discharge of melted snow water, it forms accumulated water, which seeps into t...

AI Technical Summary

Problems solved by technology

As the snow dam prevents the discharge of melted snow water, it forms accumulated water, which penetrates into the roof from the gap where the metal roof panels meet, causing water leakage

Especially in the winter heating period, the indoor temperature is high, the steam pressure is high, the outdoor temperature is low, the steam pressure is small, and the water molecules in the air diffuse from the indoor to the outdoor under the action of the steam pressure. Pressure, that is, condensation will occur, destroy the roof insulation layer, reduce the roof insulation effect, and easily cause indoor water leakage
