Firstly, installing gutter 10 at cornice on two sides of a roof steel structure truss structure 1 and purlines 2 which are constructed, measuring gutter 10 before installing gutter 10, ensuring that levelness and straightness of gutter 10 meet the installation standard at cornice position, paying off gutter 10 is required to be identical to roof board 5 at the elevation of gutter 10 position, installing two ends of gutter 10 on concrete parapet 11 and purlines 2 respectively, and sealing the junction between gutter 10 and concrete parapet 11 and purlines 2. The gutter 10 is made of stainless steel, two adjacent gutter 10 are welded, the welding seam is polished smoothly, a water closing test is needed after the gutter 10 is installed, water is poured into the gutter 10 in the water closing test to reach 2/3 of the maximum water quantity of the gutter 10, the water is closed for more than 48 hours, and the bottom of the gutter 10 is fully checked immediately after the gutter 10 is filled until water is not leaked for 48 hours.
Step two, paving a roof peripheral guard board, firstly installing the multi-ribbed plate 3 on the purline 2, firstly releasing a locating plate side line before installation so as to avoid generating larger accumulated installation errors, then sequentially overlapping and installing the multi-ribbed plate 3, releasing a composite line every time ten multi-ribbed plates 3 are placed during installation, compounding the installation size deviation of the multi-ribbed plate 3, and carrying out real-time adjustment according to the actual size of the deviation. The method is characterized in that a steam barrier film 41 is paved on the multi-rib plate 3 after the pavement is finished, the lowest part of a roof is lapped and paved upwards in specific construction, the reserved length 150 mm-300 mm is reserved at the cornice, the reserved section is temporarily fixed at the cornice, two adjacent steam barrier film 41 should follow the principles of ' lap joint parallel to the ridge direction should overlap in the downstream direction ', lap joint perpendicular to the ridge direction should overlap in the annual maximum frequency wind direction ', and the starting and the head collecting positions should be fully pasted and fixed by adopting butyl adhesive tape when the steam barrier film 41 is paved. The insulation cotton layer 42 should be laid flat, without edge lifting, without folding and with tight seams, and has a laying thickness of 70mm to 80mm, preferably 75mm in one embodiment. The steps and requirements for laying the waterproof membrane layer 43 are the same as those of the steam barrier membrane layer 41, and will not be repeated here. And finally, paving the roof plates 5 on the waterproof heat-insulating plates 4, fixedly connecting the roof plates 5 with the purlines 2 by using a fixed support, performing edge locking treatment on two adjacent roof plates 5, and reserving a gap of about 50mm at the intersection of the roof ridges on the roof plates 5 at the two sides of the roof ridge.
Step three, mounting a ridge structure, namely placing a ridge cover plate 71 at a ridge position, fixing the ridge cover plate 71 on the ridge 5 by using a fastener, sealing and connecting the ridge plates 5 at two sides of the ridge by using a ridge connecting structure 7, sealing and installing a ridge plug 73 between the ridge cover plate 71 and the ridge plates 5, sealing the opening between the ridge cover plate 71 and the ridge plates 5, and finally sealing the end part of the ridge cover plate 71 and a concrete wall by using a ridge and concrete wall connecting structure 8.
Step four, the roof ventilator 15 is installed, firstly, a region with a corresponding size is cut on the roof board 5 according to the outline dimension of the roof ventilator 15, in one embodiment, 260 mm-320 mm of the roof ventilator 15 is needed to be cut on one side of the roof board 5 when the reserved position of the roof ventilator 15 is cut, a rainwater splitter plate 93 is installed at the position, then, supporting channel steel is installed on the roof board 5, and in one specific embodiment, three supporting channel steel are installed, wherein two supporting channel steel are along the ridge direction, and the other supporting channel steel is lapped on the first two supporting channel steel. The roof ventilator 15 is fixedly arranged on the supporting channel steel, and a fastener for fixing the supporting channel steel cannot be fixed on the purline 2, so that the influence on thermal expansion and contraction of the roof board 5 is avoided. Finally, the roof ventilator 15, the roof panel 5 and the waterproof insulation board 4 are sealed by using the ventilator connecting structure 9.
The above embodiments are only a few descriptions of the inventive concept and implementation, and are not limited thereto, and the technical solutions without substantial transformation remain within the scope of protection under the inventive concept.
