The utility model discloses an in one of them embodiment, refer to figure 4, mounting panel 3 adopts the wood-Plastic who is applicable to the flat roofing of steel construction, installs the waterproof board on steel construction fossil fragments earlier, then lays wood-Plastic with the mounting means of referring to the waterproof board on the waterproof board.

The specific installation process is as follows: by adopting a laying method of spreading from front to back to two sides, the rear end of the wood-plastic floor for fixing the column body 2 is provided with a lower clamping groove 31, and the front end of the wood-plastic floor is provided with an upper clamping groove 32 mutually clamped with the lower clamping groove 31. Firstly, mounting is started from the front end of the wood-plastic floor, self-tapping screws penetrate through the first through holes 33, the front end of the wood-plastic floor is locked on a roof keel, meanwhile, the keel is distributed according to the reserved size, the first through holes 33 reserved in the lower clamping grooves 31 of the wood-plastic floor are aligned with the columns 2 one by one, then the self-tapping screws are locked in the first through holes 33, the self-tapping screws penetrate through the columns and are screwed, namely, the rear end of the wood-plastic floor is also fixed on a waterproof board, then the upper clamping grooves 32 of the second wood-plastic floor are buckled on the lower clamping grooves 31 of the first wood-plastic floor, then the self-tapping screws penetrate through the second through holes 34, after screwing, the two ends of the first wood-plastic floor and the front end of the second wood-plastic floor can be fixed on the waterproof board at the same time, and then the wood-plastic floor is sequentially mounted in a left-right spreading mode from front to back; the left side and the right side of the wood-plastic floor are respectively provided with a male groove and a female groove, and a stable male groove structure can be formed only by embedding the male groove into the female groove during installation.

Simultaneously all joint grooves and being connected between the public female groove all use the supplementary bonding of resistant time glue to strengthen the waterproof nature of seam crossing, all screw heads all sink to flush with wood-plastic floor's surface course. The joint of the left wood-plastic floor and the right wood-plastic floor can be arranged in the middle above the drainage groove 12 during installation, even if the joint of the male groove and the female groove leaks water, rainwater can be quickly drained away from the drainage groove 12, and the drainage groove 12 has a sufficient waterproof function after the waterproof board is installed.

The wood-plastic floor of about going up is fixed through self tapping screw after joint groove and public mother's groove mutually support joint through the joint groove, uses special binding off accessory sealed wood-plastic floor and waterproof board at last upper and lower port on whole wood-plastic floor, prevents that the rainwater from flowing in from the last port. Thus, the wood-plastic floor can be made into a wood-plastic floor roof which is light and safe, has heat preservation and insulation performance and high waterproof performance. The embodiment is the wood-plastic floor, and besides the wood-plastic floor, other materials such as cement fiber floor bearing plates and anticorrosive wood can be used in practical application.

The utility model discloses a load main part that the roofing produced only waterproof board and mounting panel compares in traditional cast in situ concrete roofing, and its weight descends by a wide margin, has solved steel construction building and has done the problem that the load that the flat roofing did not solve well is heavy, the expense is high, has lightweight, the installation is swift, advantage that the cost is low, has fine market value and social economic benefits.

In another embodiment of the present invention, the mounting plate 3 is made of flat photovoltaic tiles, and is suitable for an inclined roof of a steel structure. With the development of photovoltaic thin film battery technology, it is not difficult to paste photovoltaic thin films on some tiles to form photovoltaic integrated tiles, but the photovoltaic tiles need mature supporting bases to be matched with each other, so that complete functionality and decoration of the photovoltaic tiles can be realized.

Can make integrative tile of photovoltaic with mounting panel 3, like figure 5, figure 6, the joint groove and public mother's groove can be reserved according to wood-Plastic's pattern to photovoltaic tile's four borders, and the waterproof board that reuses is as supporting the base, can make the photovoltaic tile of big specification as required, and every photovoltaic tile can cover a plurality of water drainage tank and riser simultaneously under the ground, also installs according to wood-Plastic's mounting means around, just can make a section totally enclosed, have super high waterproof function, the integrative tile roofing of photovoltaic that the wholeness is strong on oblique roofing.

At present, the service life of the traditional waterproof method matched with the photovoltaic tile roof is not long enough, the service life of the photovoltaic tile is as long as 25 years, during the period, a plurality of water leaking roofs need to be dismounted for maintenance or be waterproof again, the dismounting and mounting process causes great resource waste, and the return on investment of the photovoltaic tile is influenced. And the utility model discloses a waterproof board base is supported in area adopts engineering plastics or PVC material, and life can reach decades, has solved the supporting traditional waterproof way of photovoltaic tile roofing and because of life is not enough, needs secondary dismouting photovoltaic board to do waterproofly, and reduces the problem of investment return rate, has fine market value and social economic benefits.
