In addition to the common color steel tile 、 cement Flat roof, tile roof and BIPV Isothermic door Roof type, with the technical innovation of roof waterproof materials in China, new waterproof materials are used more and more widely. among TPO Flexible waterproof roof is also widely used in domestic advanced manufacturing industry IDC Data center, automobile industry, logistics industry, airport and other large buildings.
TPO It is a thermoplastic polyolefin Waterproof roll , longer service life twenty-five It is good at low-temperature flexibility and weather resistance, and has good puncture resistance. At the same time, the bonding strength of the weld is higher than the coiled material itself, which can make the whole waterproof layer form a whole. Therefore, its height is suitable for steel structure factory buildings, color steel roofs, large commercial and civil building roofs, covering the insulation layer and TPO Material layer to solve aging and waterproof problems. It is predicted that the number of flexible roofs in the newly added roofs of industrial plants is about two thousand 10000 square meters.
TPO Flexible roof is generally based on color steel tile structure roof or concrete structure roof. In order to solve waterproof and aging problems, thermal insulation layer and long-life TPO/PVC Material layer.
How to design and construct?
Technical difficulties:
(1) use TPO The roof of waterproof coiled material has no fixed position of conventional photovoltaic support that meets the stress requirements;
(2) If fasteners are used to fix the PV support to purlins or roof steel plates, it is bound to penetrate TPO Waterproof layer, if the penetration position is not properly treated, there will be a hidden danger of water leakage;
(3) If the photovoltaic support is attached to the TPO On the surface, the support is fixed by hot melting, which may tear the waterproof layer of the connection point due to excessive wind.
Construction steps:
The main construction steps of this flexible roof are as follows:
(1) Positioning drilling: according to the design of the support drawing, carry out fixed-point drilling, and then use specific tools to drill holes ;
(2) Hole cleaning and surface cleaning: clean the rock wool in the hole, and use neutral solutions such as ethanol and acetone to clean the area requiring hot air welding around the hole ;
(3) Support installation: use professional tools to install the metal support and fasten the support to ensure firm installation ;
(4) Hot air welding: arrange professional personnel to conduct hot air welding on site ;
(5) Guide rail installation: carry out necessary tests according to relevant specifications, and install aluminum alloy main rails and secondary rails ;
(6) Assembly installation and wiring: Assembly installation and wiring.
