Description

Double-layer waterproof and thermal insulation metal roof

Technical field:

The utility model belongs to the technical field of construction engineering metal roofs, in particular to a double-layer waterproof and thermal insulation metal roof.

Background technique:

The traditional metal roof system uses insulation cotton and metal plates directly installed on the steel structure. This kind of roof system has only one insulation layer and waterproof layer. The insulation layer of the roof system has poor waterproof performance. It is suitable for general industrial and civil buildings with roof waterproof grade III , and this kind of roof system will be exposed to the sun and rain for a long time, which will cause the aging of the sealing silica gel and the surface corrosion of the metal plate. Once the metal roof plate is damaged, it will cause roof rainwater to leak, which will affect the normal use of the building. 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 the roof from the gap where the metal roof panels meet, causing water leakage. In recent years, some double-layer waterproof, thermal insulation and sound insulation roof systems have also appeared in the industry. However, most of these roof systems do not have noise reduction and sound absorption layers, nor do they have interior and exterior decoration effects, and the waterproof effect is not good.

Utility model content:

The purpose of this utility model is to provide a double-layer waterproof and heat-retaining metal roof for the above-mentioned problems, which can effectively isolate outdoor noise and absorb indoor noise.

Above-mentioned purpose realizes by following technical scheme:

The double-layer waterproof and thermal insulation metal roof comprises: secondary purlins installed on the main purlins of the building, perforated decorative panels are installed under the secondary purlins, non-woven fabric layers are laid on the perforated decorative panels, and the non-woven A sound-absorbing cotton layer is laid on the woven fabric layer, a galvanized steel wire mesh is laid on the above-mentioned sub-purlins, glass wool with aluminum foil is laid on the galvanized steel mesh, and several-shaped brackets are connected on the above-mentioned sub-purlins, and the several-shaped The support is connected to the profiled steel plate through the angle steel, the waterproof layer is set on the profiled steel plate, the Uncas net is laid on the waterproof layer, and the Uncas net is connected to the metal via a fixed support with a thermal insulation pad. layers panel.

For the double-layer waterproof and heat-preserving metal roof, the zigzag bracket is connected with the lower sub-purlin and the upper angle steel through self-tapping screws, and a layer of heat-insulating gasket is added between the zig-zag bracket and the sub-purlin.

Beneficial effect:

1. The utility model adopts the aluminum-magnesium-manganese alloy roof panel or the metal layer panel of the profiled color steel plate or the profiled titanium-zinc plate as the rigid waterproof layer, and protects the lower structure. The lower layer is made on the profiled steel plate Coating film waterproof layer (such as polyurethane coating film, JS waterproof coating film, etc.) The hidden danger of water leakage at the joints, due to the adoption of this waterproof form, the entire roof can form an integral waterproof system without gaps, and can meet the standards of waterproofing grades I and II. The noise reduction layer is set between the two waterproof layers, and the Uncass net is arranged on the second waterproof layer.

． In the utility model, the angle steel is connected with the several-shaped support through self-tapping screws, and the heat-insulation pad is set under the several-shaped support, which is connected with the sub-purlins through self-tapping screws, which avoids welding, reduces fire risks during construction, and avoids cold bridges. The height of the cavity between the profiled plate and the sound-absorbing cotton is increased, the insulation material is fluffy, the air layer is increased, the insulation effect is improved, and the amount of steel is saved at the same time.

． The utility model has reasonable layer arrangement, can effectively isolate outdoor noise, absorb indoor noise, has a beautiful and elegant structure, is convenient to install, and has excellent waterproof and thermal insulation properties.
