A kind of Wind-proof cushion for rock wool composite plate
Technical field
The present invention relates to the windproof structure of a kind of rock wool-steel plywood building, especially relate to a kind of windproof pad for rock wool-steel plywood and purlin junction.
Background technology
Rock wool-steel plywood is that rock wool-steel plywood, through high-temperature fusion fibroblast, adds appropriate cementing agent with basalt and other natural crystal etc. for primary raw material, and solidification processing is made.Rock wool-steel plywood product is widely used in steel-structure factory building, the roofing of simple and easy prefabricated house, body of wall, the furred ceiling of air cleaning room and partition now.The major advantage of rock wool-steel plywood product has: 1, fireproof performance is good.2, heat-insulation and heat-preservation.3, bright in colour.4, flexible for installation etc.
But in present rock wool-steel plywood uses, general be all used in environment thermal insulation fire-resistant and high architectural of facade aesthetic, so metope does not generally allow to see that tapping screw is on surface, the labyrinth tongue-and-groove structure of rock wool-steel plywood just arises at the historic moment, as shown in Figure 1.But other problem occurs, this tongue-and-groove structure wind loading rating is more weak thereupon, in typhoon region or the larger area of wind pressure ratio, the metope that often there will be composite plate answers typhoon to wreck.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of windproof pad can strengthening rock wool-steel plywood wind resistance is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of Wind-proof cushion for rock wool composite plate, this windproof pad is arranged in the tongue and groove of the rock wool-steel plywood be connected with purlin, described tongue and groove comprises the groove and tenon that cooperatively interact, tapping screw is provided with in tongue and groove, rock wool-steel plywood is positioned at the purlin below rock wool-steel plywood by this self-drilling connection, described windproof pad pad is located between tapping screw and rock wool-steel plywood, and windproof pad is provided with location structure, is fixed by this location structure and tenon.
Described location structure is be located at the windproof pad side buckle consistent with tenon shape.
The screw hole that windproof pad passes for tapping screw is provided with one or more, and multiple screw hole is arranged along interval, purlin direction.
The edge of described windproof pad is provided with reinforcing rib.
Described windproof pad is the windproof pad of galvanized steel plain sheet material.
Compared with prior art, the present invention has the following advantages:
1, because material is that galvanized steel plain sheet is made, price is low, is conducive to marketing, produces considerable benefit.
2, by the past at the point type at tapping screw place, stressed to change face into stressed, strengthen the intensity of rock wool-steel plywood and purlin junction, its wind resistance is improved greatly, and because be the inside being hidden in rock wool-steel plywood, original composite plate outward appearance and functional requirement can not be changed.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in figs. 2 to 4, a kind of Wind-proof cushion for rock wool composite plate, this windproof pad adopts galvanized steel plain sheet material, side is provided with buckle 1, as the location structure fixing with tenon in tongue and groove, the edge of windproof pad is provided with reinforcing rib 2 for improving the intensity of himself, and in the central authorities of windproof pad, has offered three screw holes 3 passed for tapping screw.
When mounted, as shown in Figure 5, be arranged in the tongue and groove of the rock wool-steel plywood be connected with purlin 4, this tongue and groove includes the groove 5 and tenon 6 that cooperatively interact to this windproof pad, attractive in appearance in order to roofing, and tapping screw 7 is hidden in tongue and groove.Windproof pad pad is located between tapping screw 7 and rock wool-steel plywood, and the buckle 1 of its side is consistent with tenon 6 shape, can just in time snap in tenon 6.
The present invention by the past at the point type at tapping screw place, stressed to change face into stressed, increase the intensity of rock wool-steel plywood and purlin 4 junction, make it not yielding, like this when bearing wind outside load, not yielding, thus enhance the wind resistance of whole plate, and because be the inside being hidden in rock wool-steel plywood, original composite plate outward appearance and functional requirement can not be changed.
