Embodiment 1

[0030] Embodiment 1: The construction method of flat roof. Firstly, thermal insulation tiles are laid sequentially on the structural surface of the flat roof, and polystyrene foam concrete is pumped and poured on the tiles; that is, one thermal insulation tile is placed on the lap joint, and one is poured at any time, and at the same time, the thickness and peace are in accordance with the design. Level waterproofing and slope finding require scraping. That is to say, the cast-in-place polystyrene foam concrete layer also has the function of waterproofing and slope finding on the flat surface, and it is operated in this way until the entire working surface is completed. When the cast-in-place polyphenylene foam concrete layer is in a semi-dry state, start to spray the polymer emulsion, the strength can be improved, and then scrape the waterproof coating, and bond the polymer non-woven waterproof membrane, the polymer non-woven After the woven fabric waterproofing membrane is ...

Embodiment 2

[0031] Embodiment 2: The construction method of slope roof. First of all, put the thermal insulation tiles sequentially on the structural surface of the slope roof, and use a nail gun to nail the thermal insulation tiles on the structural surface. The tail of the nail must be 10mm higher than the thermal insulation tile, so that the tail of the nail can hold Wrapped in the cast-in-place polystyrene foam concrete layer to prevent the waterproof and thermal insulation layer from sliding on the structural surface. While placing, lapping, and nailing the insulation tiles, the polystyrene foam concrete can be pumped and poured, and scraped according to the designed thickness until the entire working surface is completed. When the cast-in-place polyphenylene foam concrete layer is in a semi-dry state, start to spray the polymer emulsion, and after the strength can be reached, apply waterproof coating and bond the polymer coil. If the polymer membrane is resistant to solar radiation...

Abstract

The invention relates to a heat insulation and water prevention integration building roof and a construction method thereof, relating to the technical field of building. So-called integration firstly means heat insulation and water prevention function integration and secondarily means that a seamless integral roof is formed through a cast-in-site construction method so that the building roof has better heat insulation and water prevention effect. The heat insulation and water prevention integration building roof comprises a heat insulation tile layer and a water prevention layer sandwiched infoam concrete. The heat insulation and water prevention integration building roof is characterized in that the heat insulation tile layer is positioned on the lowest end of the building roof and formed by overlapping heat insulation tiles, and overlapping positions are provided with water-stop groove faces; and the water prevention layer is formed by casting polystyrene foam concrete on the heat insulation tile layer in site and then strickling, then spraying high molecular polymer emulsion and then coating waterproof paint in a strickling way, then paving waterproof roll materials and finally casting the foam concrete in site. The invention is not only suitable for severe cold regions in the national north, but also suitable for extremely hot regions in the national south and also has the advantages of low project cost, easy construction process operation, wide material source and suitability for wide popularization.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a thermal insulation and waterproof integrated building roof and a construction method thereof. Background technique [0002] At present, in the practice of roofing engineering in our country, the long-standing problems that have plagued the construction industry for a long time are the two problems of roof leakage and insulation performance attenuation. These two problems are due to the poor integrity of the insulation material, resulting in a large water storage space or water vapor retention space. At the same time, the moisture content of the slope finding material is too high, local water leakage on the roof, and internal condensation caused by temperature differences in winter will all make the water under the waterproof layer. With the increase of water vapor, even if the waterproof layer is well maintained and the quality of the waterproof material is high, it will not ...
