Technology based on building roof leakage prevention

Abstract

The invention discloses a technology based on building proof leakage prevention. By means of the technology based on building roof leakage prevention, construction is convenient and fast, the leakage prevention effect is good, and the waterproof term is long. The technology includes the steps that firstly, a layer of cloth film is laid on the upper surface of a roof till the upper surface of the roof is completely covered with the cloth film; secondly, non-woven fabric is laid on the upper surface of the cloth film, and a fluffy structure is adopted on the non-woven fabric; thirdly, the non-woven fabric and the cloth film are fixed above the roof through at least one pressing plate; fourthly, nutrient soil is scattered on the non-woven fabric; and fifthly, plants are planted on the non-woven fabric, and water is applied. By means of the roof leakage prevention technology, on one hand, the cloth film can be protected, the roof water prevention term can be prolonged and can be prolonged to several tens of years from three to five years; and on the other hand, the green plants are planted on the cloth film, and the effects of greening, cooling and noise lowering can be achieved on the roof.

Description

technical field [0001] The invention relates to roof leak-proof technology, in particular to a leak-proof process based on building roofs, which is convenient and fast in construction, has good leak-proof effect and long waterproof life. Background technique [0002] Buildings, especially civil buildings, mostly use prefabricated panels or reinforced concrete or iron sheet roofs. Therefore, after a period of use, they are damaged by natural stresses such as temperature, humidity, shock waves, and settlements. Cracks often appear and cause water leakage. Cement roofs The micropores and capillary pores formed in the process of hydration hardening cause leakage, and the gap between the original cement board prefabricated parts or between the cement prefabricated parts and the wall is poor, causing cracks, while the iron roof is After long-term use, the iron sheet is easy to age, rust and perforate to cause water leakage. The existing solutions include: 1. Use reinforced mesh co...

[0002] Buildings, especially civil buildings, mostly use prefabricated panels or reinforced concrete or iron sheet roofs. Therefore, after a period of use, they are damaged by natural stresses such as temperature, humidity, shock waves, and settlements. Cracks often appear and cause water leakage. Cement roofs The micropores and capillary pores formed in the process of hydration hardening cause leakage, and the gap between the original cement board prefabricated parts or between the cement prefabricated parts and the wall is poor, causing cracks, while the iron roof is After long-term use, the iron sheet is easy to age, rust and perforate to cause water leakage. The existing solutions include: 1. Use reinforced mesh concrete to cast in place; 2. Use asbestos fiber cloth and waterproof adhesive to coat the gaps; 3. Use oil blankets 4. Cover with asbestos tiles; 5. Lay a waterproof membrane on it; however, after a long time, reinforced concrete still cracks due to thermal expansion and contraction, and the original gaps between concrete prefabricated parts are due to Poor adhesion and even large cracks, and the use of asphalt has a strong smell, which will affect human health and even cause cancer. The use of waterproof membranes is also due to thermal expansion and contraction, and long-term exposure to sunlight. It is easy to cause cracks, and it is time-sensitive, even if it is a first-class waterproof, it can only last for 10 years;
