A kind of roofing cornice flashing plank member and installation and application thereof
Technical field
The present invention relates to a kind of member that is used for the roofing cornice as the flashing lath, belong to building field.
Background technology
In vogue day by day along with slope tile roof in building trade; Especially in multilayer, highrise building, use more and more widely; The mode of the tile hanging that the slope tile roof of multilayer, highrise building is adopted is owing to multilayer, FRAME ON THE ROOF OF HIGH-RISE BUILDING are in high blast district; The rainproof water function of tile is affected, and it is very general particularly under the storm environment, to leak.Leak between tile and trickle along cornice, metope easily, the water that trickles is for a long time then left a trace at cornice, metope, likeness in form " urine trace ", the sight effect that thing is built in influence.
To the problems referred to above, this area does not still have ripe solution at present.
Summary of the invention
Problem to prior art exists the invention provides a kind of roofing cornice flashing plank member, and the slope tile roof system cornice that is applied to multilayer, highrise building can be eliminated along cornice, metope and drop down water, and can make that the roof cornice is more attractive in appearance.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of roofing cornice flashing plank member comprises lath, and a side of lath is through the one-body molded alice that is connected with of junction plate, and said alice is the U font structure of indent.
Can be through said structure so that the water on the tile flow out smoothly fast when raining, and can not leave a trace at cornice, metope, prevented infringement to roofing, also guaranteed its aesthetic.
Wherein, said lath with respect to the horizontal plane has the gradient, after installing, can quicken flowing of water.
Wherein, alice surface and vertical direction flow downward thereby help water in angle of 45 degrees.
Roofing cornice flashing plank member of the present invention is processed by metal material, thereby is guaranteed its application life, and used metal material can be that building field is available arbitrarily, includes but not limited to galvanized steel plain sheet, stainless steel or copper alloy, preferably galvanized steel plain sheet.
Further, in order to improve the decay resistance of sheet material, said metal material surface has epoxy coating, the epoxy coating of especially outdoor weather resistant.
Above-mentioned galvanized steel plain sheet, epoxy coating thickness can be adjusted according to actual needs; The present invention does not limit it especially; Preferably the thickness of galvanized steel plain sheet is 0.8mm, and the double side zinc coating amount is no less than every square metre of 180 gram, and epoxy coating thickness is 10um.
Accordingly, the invention provides the installation and application of roofing cornice flashing plank member, it is installed between coiled material and the roof structure plate gets final product.
Improve through said structure; Roofing cornice flashing plank member of the present invention can effectively derive the water on the roofing rapidly when facing the rainwater environment; The water that can not occur trickling for a long time causes leaving a trace at cornice, metope; Because member is built in the roof structure, can not influence the attractive in appearance of slope tile roof simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an installment state sketch map of the present invention;
Fig. 3 is the partial enlarged drawing of Fig. 2 installation place.
The specific embodiment
With reference to figure 1, roofing cornice flashing plank member of the present invention comprises lath 1, and lath 1 is connected with crimping 3 through junction plate 2, the three in one moulding, and the edge of crimping 3 is provided with the U font structure 4 of indent.
Wherein, lath 1 with respect to the horizontal plane has the gradient, tilts; Crimping 3 and vertical direction are in angle of 45 degrees.
With reference to figure 2,3, roofing cornice flashing plank member A of the present invention is fixed between SBS coiled material 5 and the roof structure plate 6 when installing and gets final product, and piece watts 61 is installed on the roof structure plate.Be appreciated that also to be provided with some other functional structure on the roofing that for example anti-slip block piece 7 (specification is 1200), wind resistance are taken off fastener 8, headblock bar 9, cornice wind resistance and taken off fastener 81, eaves batten 10.
Shown in the above structure and the accompanying drawing, be a kind of more excellent realization of the present invention, the improvement that those skilled in the art are carried out on this basis still belongs to protection domain of the present invention like the size of type of material, each device, ratio etc.
