Water-proof heat insulation metal roof

Abstract

The waterproof heat insulating metal roof consists of metal tiles, roof frame, roof surface frame, containing parts and horizontal crossbeam, and is constructed on structure and apart from the top layer ceiling. The metal tile may be corrugated tile, flat tile or composite tile; and there is one lightning arrester earthing wire. The waterproof heat insulating metal roof can play the roles of preventing water and isoalting heat, and has very long service life, over 25 years, without need of maintenance. In addition, the used roof material may be recovered and has no environmental pollution.

Description

1. Technical field: [0001] The invention belongs to the technical field of simultaneously solving the waterproof and heat insulation of roofs in the construction industry, and relates to a metal roof with waterproof and heat insulation. 2. Background technology: [0002] According to investigations, the existing domestic and foreign waterproof and heat insulation technologies for roofs and roofs have not been able to solve these two technologies at the same time. They can only deal with waterproofing first, and then heat insulation; or deal with heat insulation first, and then deal with waterproofing. and there are only two ways to deal with it: flexible and rigid waterproof technology. Flexible roof waterproofing is mainly based on chemical raw materials, such as paper-based petroleum asphalt waterproofing membranes, polymer modified asphalt waterproofing membranes and various synthetic polymers. Coiled materials, etc., its shortcomings are: the construction process is comp...

Problems solved by technology

[0002] According to investigations, the existing domestic and foreign waterproof and heat insulation technologies for roofs and roofs have not been able to solve these two technologies at the same time. They can only deal with waterproofing first, and then heat insulation; or deal with heat insulation first, and then deal with waterproofing. and there are only two ways to deal with it: flexible and rigid waterproof technology. Flexible roof waterproofing is mainly based on chemical raw materials, such as paper-based petroleum asphalt waterproofing membranes, polymer modified asphalt waterproofing membranes and various synthetic polymers. Coiled materials, etc., its shortcomings are: the construction process is complicated, especially the service life of this type of waterproof material is short, generally not more than 25 years, and the discarded waterproof coiled material has a greater pollution to the natural environment; The above-mentioned materials cannot solve the heat insulation of the roof well, and additional heat insulation boards must be installed.

Rigid waterproof technology is mainly to make a rigid waterproof layer on the prefabricated board, that is, the overall cast-in-place rigid waterproof layer. Problems such as temperature changes are more sensitive, so admixtures or synthetic polymer materials must be added to cement mortar or concrete after reasonable blending to reduce or inhibit porosity and block capillary pores, so as to achieve the purpose of waterproofing, but Can not solve the heat insulation problem better

The disadvantage of this patent is that it cannot adapt to the needs of various roofs, such as the roofs of the stairwell entrances and exits of common buildings, the edges and corners of garden-shaped roofs and other technical problems, especially to solve the problem of roof insulation. It is proposed to use the reflective light of the metal sheet for heat insulation, which will inevitably cause light pollution in the air, and even have a certain impact on air traffic
