Abstract

The utility model discloses a waterproof light-steel roof, which comprises a structural steel plate, wherein the structural steel plate is provided with an air partition layer which is provided with a thermal insulation layer, an isolation layer is arranged on the thermal insulation layer, the isolation layer is welded with a waterproof roll material layer, the isolation layer is fixed on the structural steel plate via a second fixing bolt and a fixing gasket, the thermal insulation layer is fixed on the structural steel plate via a first fixing bolt and a fixing gasket, the fixing gaskets are in thin-type structure, the fixing gaskets are provided with grooves, and bolt holes through which the fixing bolts can pass are arranged in the grooves. With the technical scheme, the utility model has the advantages that the isolation layer and the thermal insulation layer are fixed on the structural steel plate via the fixing bolts and the fixing gaskets, so that the connection is firmer, the arrangement of the air partition layer and the thermal insulation layer makes the moisture-proof and thermal insulation effects of the light-steel roof better, and the isolation layer is welded with the waterproof roll material layer so as to enhance the waterproof performance of the light-steel roof.

Description

A kind of waterproof light-steel roofing

Technical field

The utility model relates to a kind of light-steel roofing, particularly a kind of waterproof light-steel roofing.

Background technology

Demand for development along with China's city integral level, all kinds of light-duty industrial premises, stadiums, the public place of entertainment, public building, warehouse and storage and handling facility, the exhibition hall, commerce services industries such as supermarket retail also increase year by year, corresponding all kinds of Roof system building is also more and more, the roofing of this type of building adopts light-steel roofing usually, and traditional light-steel roofing structural member exposes at present, heat insulating ability is poor, after long-time the use, the aquatic rust of leakiness, and shortcomings such as can't absorbing echo is within doors arranged, the China national Department of Intellectual Property patent No. is that 99225557.0 utility model patent discloses a kind of sound insulation sound absorption, the light-steel roofing member of insulation, comprise the metal crimp template, under the metal crimp template secondary joist is arranged, under the secondary joist main joist is arranged, there is bolt to connect supporting member with holes on the secondary joist, layer of non-woven fabric is arranged on the supporting member, glass fibre cotton is arranged on the nonwoven, one deck aluminium foil is arranged on the glass fibre cotton, the layer of metal perforated plate is arranged under the supporting member, though this light-steel roofing member has solved the problem of sound absorption and insulation, but because the restriction of its structure, waterproof, humidity resistance is relatively poor, is unsuitable at large-scale factory building, the airport, the sports palace, be extensive use of in the building classification such as supermarket.

The utility model content

The technical problem that will solve of the present utility model is at technique scheme not

A kind of waterproof light-steel roofing for insulation and good water-proof effect.

For solving the problems of the technologies described above the technical solution of the utility model be:

A kind of waterproof light-steel roofing, comprise structural steel and iron, it is characterized in that: described structural steel and iron is provided with vapour barrier, insulation layer is set on the vapour barrier, separation layer is set on the insulation layer, be welded with the waterproof roll layer on the separation layer, separation layer is fixed on the structural steel and iron by second set bolt and setting-up piece, and insulation layer is fixed on the structural steel and iron by first set bolt and setting-up piece.

Below be to further improvement in the technical proposal:

Setting-up piece is the sheet type structure.

Setting-up piece is provided with groove, has in the groove to hold the bolt hole that set bolt passes.

Adopt technique scheme, the utility model has the advantages that, separation layer and insulation layer are fixed on the structural steel and iron by set bolt bolt and setting-up piece, make connection more firm, the setting of vapour barrier, insulation layer is protection against the tide, the better heat preservation of light-steel roofing, be welded with the waterproof roll layer on the separation layer, strengthened the water proofing property of light-steel roofing.

Below in conjunction with drawings and Examples technique scheme is described further:

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Accompanying drawing 2 is the structural representation of setting-up piece.

Among the figure: 1-waterproof roll layer, 2-separation layer, 3-insulation layer, 4-first set bolt, 5-setting-up piece, 6-structural steel and iron, 7-vapour barrier, 8-second set bolt, 9-bolt hole, 10-groove.

The specific embodiment

Embodiment, as shown in Figure 1, a kind of waterproof light-steel roofing, comprise structural steel and iron 6 and the vapour barrier 7 that is arranged on the structural steel and iron 6, insulation layer 3 is set on the vapour barrier 7, separation layer 2 is set on the insulation layer 3, be welded with waterproof roll layer 1 on the separation layer 2, described separation layer 2 is identical material with waterproof roll layer 1, during installation, separation layer 2 is connected together with waterproof roll layer 1 hot gas welding, and separation layer 2 is fixed on the structural steel and iron 6 by second set bolt 8 and setting-up piece 5, and insulation layer 3 is fixed on the structural steel and iron 6 with setting-up piece 5 by first set bolt 4.

As shown in Figure 2, setting-up piece 5 is the sheet type structure, and setting-up piece 5 is provided with groove 10, has in the groove 10 and can hold the bolt hole 9 that set bolt passes.

Adopt technique scheme, the utility model has the advantages that separation layer and heat-insulation layer pass through set bolt Be fixed on the structural steel and iron with setting-up piece, make connection more firm, the setting of vapour barrier, heat-insulation layer is light steel The protection against the tide of roofing, better heat preservation are welded with the waterproof roll layer on the separation layer, strengthened light-steel roofing Water proofing property.
