[0049] S2, install the stainless steel gutter system 11 while installing the roof purlin;

[0050] S3, when installing the steel bottom plate 810 in S1, attention should be paid to the flatness of the bottom plate, and one wave crest is overlapped transversely, used for the installation of the stainless steel roof panel 83 in the later period;

[0051] S4, when installing the stainless steel roof panel 83, continuous welding is adopted first and then 360-degree occlusion system is adopted, the surface is designed in a concealed manner without perforation and puncture;

[0052] In operation, the steel structure main purlin 101 is hoisted by a tower crane, and after hoisting, the metal roof is divided into four areas for construction according to the construction method. In the first step, the secondary purlin 87 and the purlin support 871 of the first area are installed first, in the second step, the stainless steel roof panel 83 of the first area is installed, then the secondary purlin 87 of the second area is installed, in the third step, the decorative aluminum plate of the first area is installed, and the stainless steel roof of the second area is installed, the secondary purlin 87 of the third area is installed, in the fourth step, the decorative aluminum plate of the second area is installed, the stainless steel roof of the third area is installed, and the secondary purlin 87 of the fourth area is installed. While installing in each area, the installation of sound-absorbing cotton 89 and galvanized steel plate 86 and other structures is also required. The secondary purlin 87 is arranged in a specific wavy curve, and the spacing between adjacent purlins is between 900mm-1100mm. The purlin support 871 is connected with the main steel structure 10, and the included angle between the purlin support 871 and the wing plate of the truss steel pipe strip is 90°±1°, and the positional deviation is within 5mm. The aluminum single plate 81 is made of thick fluorocarbon material, and the aluminum single plate 81 is fixed by a keel made of anodized aluminum alloy profile, which is fixed on the stainless steel roof panel 83 by a clamp. The standard plate of the aluminum single plate 81 has a side length of 700mm*3000mm, and the folded edge is 20mm. The plates are designed as a slotted type. The stainless steel gutter main body 1 is a metal roof drainage system, which adopts a matte stainless steel drainage gutter. The natural drainage of the siphon drainage system and the curved surface form itself drains rainwater to the outside. The total area is about 2600㎡, and 15 water collection wells are arranged at the lowest point of the roof. The insulation layer structure 8 is installed on the steel bottom plate 810, which is fixedly connected with the main purlin 101. Then, the air barrier film and the sound-absorbing cotton 89 are laid on the steel bottom plate 810. When installing the air barrier film, it must be ensured that the base layer has no obvious protrusions or depressions to ensure the flatness of the PE air barrier film laying and prevent the sound-absorbing cotton 89 from warping. If there is water, snow and ice, they must be removed to avoid water vapor in the completed roof system. The sound-absorbing cotton 89 is arranged above the air barrier film. When the roof slope is within 3%, the coil material should be parallel to the ridge; when the roof slope is between 3%-5%, the coil material can be parallel or perpendicular to the ridge; and when the roof slope is greater than 15%, the coil material must be perpendicular to the ridge. Since the slope of the project in this embodiment is greater than 15%, the air barrier film is laid longitudinally from bottom to top along the roof slope. The air barrier film laying needs to be water-following lap joint, and the lap joint width should not be less than the design requirement, and the lap joint size is 100mm. When installing the sound-absorbing cotton 89, it is directly laid on the air barrier film, which is required to be completely covered and tightly attached. There should be no gap between the cotton and the cotton. The interfaces of the adjacent two sound-absorbing cottons 89 should be tightly connected without gaps. The sound-absorbing cotton 89 should be laid in a staggered manner with a staggered distance of 300mm. The insulation rock wool 88 is laid on the sound-absorbing cotton 89. The insulation rock wool 88 must be laid flat, without warping, folding and tight joints.The thermal insulation rock wool 88 must be laid and cut according to the condition of the roof, the thermal insulation rock wool 88 is laid in staggered manner, then the galvanized steel plate 86 is laid on the thermal insulation rock wool 88, the waterproof roll material 85 is laid on the galvanized steel plate 86, then the support is laid on the waterproof roll material 85, the noise reduction cotton 84 is laid on the support, the stainless steel roof panel 83 is installed above the noise reduction cotton 84, the stainless steel roof panel 83 is connected with the support, and a continuous welding method is adopted, and a wave-shaped metal roof is formed according to the wave shape, after the welding is completed, the aluminum alloy furring 82 is installed on the stainless steel roof panel 83, and the aluminum veneer 81 is installed on the aluminum alloy furring 82, the roof panel adopts the method that the stainless steel is continuously welded and then is 360-degree engaged, and the surface is hidden type installation without perforation and puncture, wherein the continuous welding is that the automatic or handheld welding equipment is used to continuously and uninterruptedly weld the joint between the adjacent stainless steel roof panels 83 (usually the side or bottom lap joint of the plate rib), the purpose is to melt the metals of the two panels together to form a continuous and homogeneous whole, fundamentally eliminating the possibility of rain, air and dust invading from the horizontal joint of the panel, and at the same time, the overall strength of the roof panel is enhanced, the structural rigidity is improved, which is the first and most critical waterproof line, and realizes the “overall waterproof”, and the 360-degree engagement system is a precise mechanical locking process, the long side (vertical rib) of the roof panel is pre-rolled into a specific shape (usually with an inner hook and an outer roll), during installation, the engagement machine is used to buckle the vertical rib of one panel with the vertical rib of the adjacent panel, and then the machine drives the vertical rib to rotate 360 degrees to tightly roll, lock and understand as two “hooks” are buckled with each other and then are rotated and tightened to form a double-locking closed state, which provides strong anti-pulling force (resisting negative wind pressure and preventing being blown open) and anti-shear force, while being locked, the system usually designs a certain sliding space to allow the metal panel to freely stretch and contract due to temperature changes to avoid stress deformation, and the tight mechanical engagement itself forms a second wind and rain barrier, mainly providing structural strength and dynamic protection, through the above process, the surface is hidden type installation without perforation and puncture, which means that there is no exposed fastener such as screw, rivet and drawn nail on the entire visible surface (large area of the roof panel), the traditional screw fixed roof has a “hole” penetrating the panel for each screw, which is a potential leakage point and weak point. First, the fixing support is fixed on the roof structure layer (such as purlin) by screw, then the vertical rib of the roof panel is buckled on the specific clamping groove of the support 102, and finally, the vertical rib is locked and covered together with the support 102 through the above 360-degree engagement process. In this way, all penetrating fasteners are sealed inside the engaged rib and cannot be seen or contacted by wind and rain.

In this project, a 0.5 mm stainless steel continuously welded roof panel is used as a lightning arrester, and the lightning current is connected through the roof waterproof board. The fixing seat is connected to the purlin through a copper wire and a large number of self-drilling and self-tapping screws, and finally to the entire steel structure.
