Curvature, the consistent size at the curvature of this bracing frame 3, size and this curved reflector 2 back sides.These bracing frame 3 openings are a bit larger tham the opening of this curved reflector 2, and these bracing frame 3 openings are a bit larger tham 1.2m, and the centre distance of two adjacent bracing frames is 2.4m.
This plane glass structure 6 is of a size of that 1.22m is long, and 2.4m is wide, and 3mm is thick, and the material of this plane glass structure 6 is the simple glass of edging and/or non-tempering not.
This intermediate adhesive layer 7 has certain thickness, and for example about 0.2mm, can be hot-melt film, and it adopts is multipolymer (EVA), the polyvinyl butyral (PVB) of the good high-quality ethene of weatherability and vinyl acetate.And the size of this hot-melt film is more slightly larger than these plane glass structure 6 sizes, as this hot-melt film is of a size of 1.25m * 2.5m.
This intermediate adhesive layer 7 can be also hot-melt film and reinforce sizing thing, and this hot-melt film is arranged on this reinforcing sizing thing.And it is more slightly larger than the size of this flat glass 6 that this reinforces sizing thing size, as this reinforcing sizing thing is of a size of 1.25m * 2.5m, and this reinforcing sizing thing material is glass fabric or nonwoven fabrics.
This intermediate adhesive layer 7 also can adopt general chemistry cementing agent, and this general chemistry cementing agent is single component, bi-component or polycomponent cementing agent.In addition, this intermediate adhesive layer 7 can be also general chemistry cementing agent and reinforce sizing thing, so that this flat glass mirror 8 bonds to merge with this flat glass 6 completely, closely be combined as a whole equably.This kind adopts the intermediate adhesive layer of general chemistry cementing agent, with low cost and simple to operate, but effect is not the most desirable.In order to obtain the physical strength of maximum curved reflector 2, prevent from breaking, optimum intermediate adhesive layer 7 comprises that at least 2 layers are reinforced on sizing thing.
These flat glass mirror 8 sizes are thick more slightly smaller than these plane glass structure 6 dimensional thickness, as this flat glass mirror 8 is of a size of 1.2m * 2.4m, and the not edging that thickness is 2mm and/or the simple glass of non-tempering.
In Fig. 3, upwards, the minute surface of this flat glass mirror 8 (scribbling the one side in reflection horizon) down and its next-door neighbour's intermediate adhesive layer 7 for the curved surface of this mirror holder 1.This kind is placed in inner mode by the reflecting surface that scribbles reflection horizon, greatly reduced wearing and tearing and the destruction of coating.
Plane glass structure 6 in the above Fig. 1 to Fig. 3 is structures of one deck flat glass.In fact, the structure that this plane glass structure 6 can be multilayer planar glass.The following stated Fig. 4 will, with plane glass structure 6 by example that two-layer flat glass is configured to, elaborate the structure of multilayer planar glass; And the plane glass structure 6 of describing in Fig. 5 can be single flat surface glass structure, it can be also the multilayer planar glass structure being formed by multilayer planar glass.
Fig. 4 is the perspective view of curved reflector in accordance with another embodiment of the present invention.This curved reflector comprises flat glass mirror 8, intermediate adhesive layer 7 and plane glass structure.Wherein, this plane glass structure comprises the first flat glass 13, tack coat 20, the second flat glass 12.
It should be noted that, this plane glass structure is not limited to the double-layer structure shown in Fig. 4, i.e. the present invention is not limited at and only comprises the first flat glass 13, the second flat glass 12, can also comprise multilayer planar glass, thereby forms multilayer planar glass structure.
In Fig. 4, plane glass structure is fixed after forming curved surface by two-layer flat glass (i.e. the first flat glass 13, the second flat glass 12) by tack coat 20; And the concrete structure of this tack coat, principle of work are identical with structure and the principle of work of described intermediate adhesive layer 7 above.
In Fig. 4, this plane glass structure (comprising the first flat glass 13, tack coat 20, the second flat glass 12) is positioned under this flat glass mirror 8.
