Description
Technical Field
The invention relates to the field of metal roof maintenance systems, in particular to a double-layer waterproof gutter system and a construction method thereof.
Background
In recent years, metal maintenance system roofs are favored by more and more owners and investors, and are widely applied to the fields of industrial buildings and public buildings in view of the advantages of low cost, short construction period, wide application range of building appearance and the like, and building waterproofing always pursues an optimal solution, and buildings adopt different roof waterproofing grades according to different application occasions and service lives.
According to projects above domestic medium-scale in recent years, the waterproof grade of the metal roof is designed to be the first-level roof waterproof grade, namely the roof is provided with two waterproof fortifications. According to current metal roofing construction technology, the combination commonly used is upper metal roof boarding + lower floor TPO polymer waterproofing membrane (TPO for short hereafter), and two kinds of materials are soft one just rigid intercoupling, and the perfect one-level roofing waterproof requirement of satisfying. But still have deficiencies from the standpoint of gutter systems alone. Fig. 1 is a conventional gutter system, and fig. 2 is a partial enlarged node diagram, which mainly has the following two disadvantages:
first, there is a drainage defect at the junction of the roofing system and the gutter system. Roofing TPO and gutter system TPO should realize whole linking up, and the gutter board exists in gutter TPO top alone again, and according to the drainage principle, inside roofing system rivers should flow into the gutter, because of gutter system and roofing system TPO do not carry out the structural connection, can't guarantee that the rivers get into the gutter system completely.
Secondly, the metal roof gutter system is mostly made of austenite 304 or austenite 316 stainless steel materials, and is formed in a factory according to actual sizes and then is spliced and welded on site. The normal construction flow is that the gutter is put in place and then is spliced and welded, the argon arc welding process can generate high temperature of more than 2000 ℃, and TPO is melted and deformed at the temperature of 700-800 ℃. How to control the integrity of TPO in the welding process of the gutter plate is taken as the control key point of the roof waterproof performance.
