Waterproof and thermal insulation structure for light-steel roofing

Abstract

The invention relates to a waterproof and thermal insulation structure for a light-steel roofing, which belongs to the technical field of roofing waterproofing and thermal insulation for buildings. The waterproof and thermal insulation structure comprises a vapor barrier layer, a thermal insulation layer, a fire protection layer and a waterproof layer, wherein, the thermal insulation layer is arranged on the vapor barrier layer, the fire protection layer is arranged on the thermal insulation layer, and the waterproof layer is combined on the fire protection layer. The invention has the advantages that the invention has ideal waterproof and thermal insulation effects, can ensure that the light-steel roofing is not condensed indoors, has simple structure and can be suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of roof waterproofing and heat preservation of buildings, and in particular relates to a waterproof and heat preservation structure for light steel roofs. Background technique [0002] Light steel roof has the advantages of fast construction, saving materials and reducing construction costs, recyclable and off-site reuse, so it is widely used in standard factory buildings, sports venues, cultural and entertainment venues, public buildings, port terminals, warehouses, exhibitions The construction of restaurants, supermarkets and various markets. However, the light steel roof also has its own poor waterproof and thermal insulation effect. The improvement scheme proposed for the waterproof and thermal insulation of the light steel roof, such as the light steel lightweight roof panel recommended by the Chinese Utility Model Patent Authorization Announcement No. CN2307857Y, is made of The channel-shaped steel co...

Problems solved by technology

However, the light steel roof also has its own poor waterproof and thermal insulation effect. The improvement scheme proposed for the waterproof and thermal insulation of the light steel roof, such as the light steel lightweight roof panel recommended by the Chinese Utility Model Patent Authorization Announcement No. CN2307857Y, is made of The channel-shaped steel cold-bent from the steel plate is used as the frame, that is, as the skeleton, and the steel stringers are used as the beams. The steel stringers are arranged at equal distances in the aforementioned frame and the two directions are perpendicular to form a grid, and light weight is filled in each grid. Light insulation material block, wrap or cover the steel mesh on the upper and lower sides of the light insulation material block, and then spray cement mortar on the outside of the upper and lower steel mesh, so that the steel mesh sheet is wrapped in cement mortar

Because this kind of structure requires both wet construction and dry construction, it is not only troublesome to construct, but also the cement mortar wrapped on the surface of the stencil will crack and lose its waterproof effect as time goes by; the material consumption is large and it is not suitable It is suitable for industrialized production; the above-mentioned patented structure does not have the adaptability to the deformation of the building, and neither the media nor the actual light steel roof has any waterproof and thermal insulation structure similar to the above-mentioned

However, the problem of condensation (condensed water) on the roof of light steel structure has not been solved by people, especially for industries such as papermaking, electronics, light industry and machinery, which have very strict requirements on indoor humidity. Therefore, How to make the light steel roof used by buildings in these industries have a good waterproof and thermal insulation effect has always been concerned by the construction industry and manufacturers of building materials, and it has also become a focus of attention.
