Description

Metal plate flexible waterproof roof and roof panel used therein

technical field

The utility model relates to the technical field of steel structures, in particular to a metal roof panel and a metal plate flexible waterproof roof constructed therefrom.

Background technique

At present, the existing steel structure roof waterproof structure has the following two types:

1. Rigid metal plate waterproof roof is pressed with thin steel plate (stainless steel plate, aluminum alloy plate or color-coated steel plate, etc.), mechanically occluded on site or fixed with self-tapping screws to achieve rigid waterproofing. Rigid waterproofing has poor waterproof performance. Under the combined action of strong winds and heavy rain, when there is local wind pressure on the roof, rainwater will leak down the board seams under the action of wind pressure. When there is snow on the roof in winter, the snow in the gutter is thick and then melts, while the snow on the roof is thin and melts first, and the snow that melts first has nowhere to flow and will leak into the roof along the cracks. The rigid waterproof roof of profiled steel plate generally has poor wind resistance.

2. The flexible membrane waterproof roof is laid on the roof of the steel structure with flexible membranes, which has the disadvantages of high cost and short durability.

In order to solve the first technical problem above, the technical solution provided by the utility model is: a roof panel, comprising: a metal panel, which is rectangular and has four sides, and among the four sides of the metal panel, two adjacent One side is folded into a hem, and the other two sides are folded into a groove.

Preferably, an insulating layer is provided on the bottom surface of the metal panel.

Preferably, the bottom surface of the thermal insulation layer is provided with a metal bottom plate, and the thermal insulation layer is wrapped between the metal bottom plate and the metal panel.

In order to solve the second technical problem of the above technique, the technical solution provided by the utility model is: a metal plate flexible waterproof roof, comprising: a plurality of said roof panels arranged side by side, and among the two adjacent roof panels , the hem of one roof panel is fixed to the bottom of the groove of the other roof panel by fasteners, the groove is provided with waterproof cement, and the opening of the groove is provided with a butt joint The two roof panels on both sides are respectively bonded waterproof membrane strips.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

1) Among the four sides of the metal panel, two adjacent sides are folded into folds, and the other two sides are folded into grooves, so when used, among the two adjacent roof panels, one roof The edge of the panel can be placed in the groove of another roof panel, and fixed to the bottom of the groove by fasteners, and then the metal panel is fixed on the support plate or purlin of the lower roof. This structure is convenient for roofing. The connection between the panels is conducive to forming a completely sealed structure.

2) The waterproof mastic forms the first waterproofing in the groove, and forms an anti-corrosion structure on the metal plate and fasteners; a waterproof membrane strip is bonded to the groove and the waterproof mastic, and the waterproof membrane strip and the butt joint The roof panels on both sides are tightly pasted to form a second waterproof and anti-corrosion layer, and the waterproof membrane strip is also a durable protective layer for waterproof cement to prevent aging and heat softening. Under the above two waterproof measures, the joints of the roof panels can be guaranteed to meet the sealing and waterproof requirements, and the wind resistance of the roof panels can be greatly improved.

3) A variety of panels can be designed according to needs, for example, the metal panel can be combined with the thermal insulation layer to form a roof panel with both waterproof and thermal insulation effects, and a metal bottom plate can be further set to wrap the thermal insulation layer between the metal panel and the metal bottom panel space, so that the roof panel integrates bearing, heat preservation and waterproofing. Although the production is a bit more complicated, it is easy to install, low in cost, and has high roof rigidity.

detailed description

Example 1

As shown in FIG. 1 , a metal sheet flexible waterproof roof includes a plurality of roof panels 1 arranged side by side.

As shown in Figure 2, the roof panel 1 includes a metal panel 11 (such as a stainless steel plate, aluminum alloy sheet or color-coated steel plate, etc.), which is rectangular and has four sides. Among the four sides of the metal panel 11, the adjacent two The sides are folded into folds 12 respectively, and the other two sides are folded into grooves 13 respectively.

As shown in Figure 3, during construction, the grooves 13 of two adjacent metal panels 11 are placed on the lower side, the folded edge 12 is placed on the upper side, and the folded edge 12 is pressed in with fasteners such as self-tapping screws 4 or pull rivets. Groove 13, the two are firmly fixed together, and are fixed together on the support plate or purlin below. Fill the groove 13 with waterproof cement 2, fill the gap formed by the groove 13 and the flange 12 and the gap around the self-tapping screw 4 to form the first waterproofing. On the groove 13, use hot melt adhesive or self-adhesive glue to paste a waterproof coiled material strip 3 again, the waterproof coiled material strip 3 and the metal panels 11 on both sides of the butt joint are pasted tightly, and the waterproof coiled material strip 3 forms the second waterproofing, And form a protective layer to the waterproof cement 2 below, prevent from flowing under the high temperature in summer and prevent aging under the sun's ultraviolet radiation. All gaps have two layers of waterproofing, which can better ensure the sealing, waterproofing and windproofing of the roof.

The metal plate flexible waterproof roof only considers the sealing, waterproof and windproof requirements, which is the basic type of the utility model.
