Background

At present, as most buildings in China enter a maintenance period, the maintenance of the roof of the old building becomes a hotspot and a difficulty in the current waterproof field, and the form of the roof of the old building is complex and various. Some roofs are surface layers of the dinnerware, some are surface layers of original aged asphalt coiled materials, some are concrete surface layers pulverized after aging, and some are colored light steel coiled materials. Even some roofing exists in several situations.

The prior common coiled material construction method is a method fully adhered to a base surface, and the method has high requirements on the base surface, and the base surface needs to be flat and solid. The individual bonding methods also require that the base surface be free of moisture or must be wet. Another construction method is a mechanical fixing method, in which the coiled material is fixed on the base layer by screws and gaskets, and the construction method requires that the base surface must be firm and the nail-eating property thereof must meet certain requirements. Which is difficult to reach for most roofing. Another construction method is to use a hollow-laid roof to lay a layer of crushed stone or concrete on the surface of the coiled material. This method increases the load on the old roofing, and some old districts are difficult to reach for the transportation of concrete or gravel, and extremely difficult for the purchase of small quantities of concrete.

The rigid-flexible composite waterproof layer of the glass magnesium board TPO coiled material is formed in a one-step composite mode on a production line. When the waterproof fireproof door is applied to a field, the functions of smooth surface, quick installation, fire prevention and water prevention can be achieved by simple installation.

Compared with the prior art, the utility model beneficial effect who has is:

the utility model provides a glass magnesium board TPO coiled material rigid and flexible composite waterproof layer. Can be directly placed on the surface of a roof, does not need to be bonded with a base layer, does not need to be mechanically fixed with the base layer, and does not need to be pressed against the upper surface of a coiled material. The composite system is directly placed on the roof, and the self weight of the composite system can achieve the effect of stabilizing the coiled material. The weather-resistant TPO carcass layer on the upper surface can still meet the requirement of long-time exposed use, and the TPO carcass layer can be waterproof and fireproof.

The utility model discloses a glass magnesium board TPO coiled material rigid and flexible composite waterproof layer can also solve the influence of weather to water-proof construction when having solved the problem of job site installation. For the traditional full-adhesion method, the base surface is required to be a dry base surface or a wet base surface, and construction becomes a problem in rainy or no-rain weather. The simple installation mode solves the trouble of weather on construction. The waterproof construction period of the old roof of the building is greatly improved.
