[0038] Working Principle: When the metal roof structure needs to be installed and fixed, it needs to be carried out according to the following steps:

[0039] (1) Installation of angle steel 10 and second bolts 11: a. At the intersection of the divided grid, use an electric hammer (existing equipment) to drill holes required for the installation of the second bolts 11 (do not penetrate the concrete layer, two holes at each intersection); b. Fix the angle steel 10 with the second bolts 11; c. Weld the supporting square tube 7 to the angle code 10;

[0040] (2) Installation of the keel square tube 6: a. Transport the keel square tube 6 to the required roof according to the required quantity and size; b. Weld the keel square tube 6 to the supporting square tube 7;

[0041] (3) Installation process of the insulation layer 8: a. Check the specifications, quantity, thickness, packaging, and moisture conditions. Unqualified ones, especially those that have been exposed to rain, must be cleared or processed. Thickness measurement: The insulation cotton is fully compressed after being rolled and packaged. The thickness can be measured after the insulation cotton is fully rebounded after being unrolled and patted or rolled over for more than 4 hours; b. The storage site should be in a warehouse, which should be kept dry and equipped with windproof, rainproof and fireproof facilities. When temporarily stacked on site, the surface should be covered with fireproof cloth and fire-fighting equipment should be provided; c. The materials are lifted to the roof by installing a fixed pulley on the roof. The insulation materials transported to the roof should be used up at the same time to avoid large-scale stacking; d. The insulation cotton should be close to the surface of the base layer, the plane joints should be squeezed and tightly joined, and the joints of the upper and lower layers should be staggered; when the roof slope is large, it is advisable to use metal or plastic special fixings to fix the insulation cotton to the base layer; once the insulation cotton is filled, people are not allowed to step on it;

[0042] (4) Installation process of the bearing layer 5: a. The length of the bearing layer 5 is measured by the engineers at the construction site, and the measured values ​​of each part are summarized as a bearing layer 5 processing order, which is then handed over to the factory for processing; b. The bearing layer 5 is transported to the construction site, and then moved to the roof operation area by a combination of manual and mechanical methods, and stacked in the material area, paying attention to rain and waterproof measures; c. Before installation, the bearing layer 5 installation control line must be popped out according to the bearing layer 5 panel design drawing to control the installation position, and it must be laid above the roof keel square tube 6, and then fixed to the keel square tube 6 with self-tapping screws; d. The laying time of the bearing layer 5 The distance must meet the design requirements, and the connection and fixation with the keel square tube 6 should be reliably anchored. When fixing the laid bearing layer 5 with self-tapping screws, the self-tapping screws should be on a horizontal line and checked with a ruler. Any error exceeding 8mm should be re-trimmed and fixed so that the exposed screws will naturally become a straight line when they are straight and an arc when they are curved, with a smooth transition; e. The longitudinal overlap length between each bearing layer 5 shall not be less than 80mm, and the horizontal overlaps shall be a wave crest. If a large gap occurs when the plates contact each other, aluminum rivets should be used to properly tighten them; f. The installed bearing layer 5 has tight joints, straight joints, reliable anchoring, and a straight longitudinal and transverse overlap, and the plate surface is flat and clean;

[0043] (5) Installation of leveling layer 4: a. After the leveling layer 4 is sent to the site from the factory, pay attention to the amount of each roof when hoisting on site; b. The leveling layer 4 and the bearing layer 5 are fixed with rivets at a spacing of 250mm*500mm; c. Each board from top to bottom of the bearing layer 5 must be overlapped; d. The bearing layer 5 should be flat after construction;

[0044] (6) Installation of waterproof layer 3: a. Deliver 1.5 mm thick double-sided waterproof layer 3 to the construction site; b. Deliver as many as needed to the roof, and then transport it to the installation site manually for paving; c. Before installing the waterproof layer 3, clean the debris on the leveling layer 4, and then lay the waterproof layer 3 on it. It must be fully laid without missing or underlaying, and the corners must still be laid tightly; d. When the roof slope is greater than 25%, the waterproof layer 3 is fixed by full bonding and nailing. The waterproof layer 3 is laid parallel to the ridge, and the upper and lower waterproof layers 3 are not The waterproof layers 3 parallel to the ridge should be laid vertically. The overlapping seams of the waterproof layers 3 parallel to the ridge should be in the direction of the water flow. The overlapping seams of the short sides of the two adjacent waterproof layers 3 should be staggered and should not be less than 100mm. The overlapping seams of the long sides should be staggered and should not be less than 100mm. When laying the waterproof layer 3, the isolation paper at the bottom of the self-adhesive should be completely torn off. The air under the waterproof layer 3 should be exhausted and the waterproof layer 3 should be rolled and pasted firmly. The rolled material should be smooth and straight, the overlapping size should be accurate, and it should not be twisted or wrinkled. When constructing at low temperature, the joints should be heated with hot air and then pasted immediately.

[0045] (7) Installation of noise reduction layer 2: The 6 mm noise reduction layer is installed together with the metal roof panel 1. Before installing the metal roof panel 1, the noise reduction layer 2 is laid flat on the 1.5 mm waterproof layer 3. The laying should be smooth and no gaps should be left;

[0046] (8) Installation of metal roof panels 1: a. Put the metal roof panels 1 in place. When installing the metal roof panels 1, place each panel in the correct position according to the detailed construction drawing. The male buckle of the panel must be completely hooked by the stainless steel fastener. There should be no missing buckle that is not connected to the fixed locking plate. When laying the metal roof panels 1, lay the noise reduction layer 2 first. During the installation of the metal roof panels 1, do not walk on the unfixed metal roof panels 1. For safety reasons, the metal roof panels 1 must be locked immediately after being fastened to achieve composite force and enhance its bearing capacity. b. Installation of stainless steel fasteners: The metal roof panels 1 are connected to the leveling layer 4 by stainless steel fasteners. The fasteners are fixed by 2 aluminum rivets. The roof is installed from the parapet or the middle direction according to the design, and the installation direction is from the large side to the small side. Each panel is measured and laid first, and then fixed on the small side with stainless steel fasteners at a spacing of 400mm. The large side of the next metal roof panel 1 bites the small side of the previous metal roof panel 1 and then fixes the small side of the next metal roof panel 1. In this project, each stainless steel fastener needs 2 screws. In addition, the number of stainless steel fasteners determines the wind resistance of the metal roof panel 1. Therefore, the number of stainless steel fasteners along the length of the board should be strictly installed according to the design drawings, and no missing or insufficient installation is allowed; c. Metal roof Edge locking of board 1: The use of the metal roof board 1 locking machine (existing equipment) should be matched with its board. The tension adjustment device should be checked frequently during edge locking. The edge locking machine can be checked to see if it is working properly by measuring the diameter of the board rib after edge locking. When locking the edge of the metal roof board 1, a worker first walks along the bite of the boards in front, fastening the female buckle of the upper board and the male buckle of the lower board while walking; the next person uses a biter to manually bite the metal roof board 1 tightly. For this project, the key to the quality of edge locking lies in whether the overlapping edges are tightly joined with strong force during the edge biting process. The metal roof board 1 in place on the same day must complete the edge biting to ensure that it is done at night. The panels installed during the evening wind will not be damaged by bad weather; d. Setting of the fixing points of the metal roof panel 1: The setting of the fixing points of the metal roof panel 1 is very important, because after the stainless steel fasteners are engaged with the metal roof panel 1, the metal roof panel 1 can still slide relative to the stainless steel fasteners. In order to prevent the installed roof from sliding down, after fixing it to the stainless steel fasteners, use scissors to cut the small edge of the metal roof panel 1 above the stainless steel fasteners and roll it back on the stainless steel fasteners, and then engage it with the large edge of the next metal roof panel 1 to prevent the metal roof panel 1 from sliding down due to weather reasons. Each panel should be fixed at 2-3 points depending on its length and slope.

[0047] The first reinforcing plate 903 and the second reinforcing plate 904 are buried in the thermal insulation layer 8 , so as to significantly improve the structural strength of the thermal insulation layer 8 .
