Abstract

A steel and aluminium compound plate is provided, which comprises a panel, a soleplate and core plates positioned between the former two plates. The section of the core plates is shaped in depression; a plurality of cavity bodies formed by overlaying are arranged between the core plates. The structure as above has good heat preservation and insulation function as well as certain sound insulation effect with convenient transportation and installation, which overcomes the defect as rapid heat transmission of single layer plate. In addition, the compound plate, for the cavity bodies are separated, is light for several times compared with the aluminium plate or steel plate of the same thickness, thus largely reducing the weight of the building and lowering the construction cost.

Description

Steel-aluminium composite board

The utility model relates to the Steel-aluminium composite board that uses in a kind of building.

Along with the variation of terrestrial climate, environment pollution is day by day abominable, and acid rain concentration increases, and seriously corrodes buildings, and traditional galvanized steel plain sheet can't have been resisted the erosion of acid rain.The insulation of lamina in addition, effect of heat insulation are poor, and conducting heat at high temperature season is exceedingly fast, and therefore cause the defective of the high and heat radiation difficulty of the indoor temperature in steel work workshop, public place.

The purpose of this utility model is to provide a kind of Steel-aluminium composite board of in light weight, corrosion-resistant, heat insulation and high insulating effect.

For achieving the above object, the technical solution of the utility model is: a kind of Steel-aluminium composite board, comprise panel, base plate and be located at panel and base plate between central layer, it is characterized in that: the section of central layer is the pit shape.

As further improvement of the utility model, described pit shape is concavo-convex flute profile.

As another kind of improvement the of the present utility model, described central layer comprises two central layers, and they superpose mutually and constitute a plurality of cavitys, fuse by adhesives between the central layer.

As another improvement of the present utility model, described central layer comprises two central layers and middle plate, forms a plurality of cavitys between them, and middle plate is located between the central layer.

As another improvement of the present utility model, between central layer, inject polyurethane or foamed polystyrene body in the formed cavity; Or between central layer and middle plate, inject polyurethane or foamed polystyrene body in the formed cavity; On panel and base plate, also be provided with the weatherability coating layer.

Because the shape of central layer adopts concavo-convex flute profile, constitute a body and form a plurality of cavitys by adhesives between the central layer, or between central layer and middle plate, constitute a plurality of cavitys; This structure not only has good incubation and thermal insulation function, also has certain sound insulation value, transportation and installation are all convenient, overcome lamina heat and transmitted fast shortcoming, because cavity is separated, compare with the aluminium sheet or the steel plate of same thickness in addition, its weight can alleviate several times, alleviate the weight of building so greatly, reduced its building costs.

Fig. 3 is the structural representation of the another kind of embodiment of the utility model;

Fig. 4 is the structural representation of another embodiment of the utility model;

Fig. 5 is the structural representation of another embodiment of the utility model.

Below in conjunction with accompanying drawing several embodiment of the present utility model are specifically described:

Fig. 2 has shown a kind of embodiment of the present utility model, and it is a kind of Steel-aluminium composite board, comprise panel 2, base plate 3 and be located at panel 2 and base plate 3 between central layer 1, the section of central layer 1 is the pit shape; Shown in Figure 1, described pit shape is concavo-convex flute profile.

As be used for the big building of span, the Steel-aluminium composite board that needs thickening is to gain in strength and during thickness, can adopt following embodiment:

Fig. 3 has shown another embodiment of the present utility model, and central layer 1 is formed by stacking mutually by central layer 1-1 and central layer 1-2, and forms a plurality of cavitys 4, fuses by adhesives between central layer 1-1 and the central layer 1-2.Be attached with panel 2 and base plate 3 at the upper surface of central layer 1-1, the soffit of central layer 1-2 by adhesives.

Fig. 4 has shown another kind of embodiment of the present utility model; Central layer 1 comprises central layer 1-1, central layer 1-2 and middle plate 5, and forms a plurality of cavitys 6, and middle plate 5 is located between central layer 1-1 and the central layer 1-2.Be attached with panel 2 and base plate 3 at the upper surface of central layer 1-1, the soffit of central layer 1-2 by adhesives.

Fig. 5 has shown another embodiment of the present utility model, on the basis of embodiment shown in Figure 3, injects polyurethane (PU) or polystyrene (EPS) foaming body 7 in cavity 4, can fill up the space of cavity 4 like this, increases its bulk strength and planeness.Since the countless micropores after the expanded material foaming except that can be heat insulation, the insulation, but more sound insulation, be a kind of very effective light-weight building sheet material, in addition, central layer 1-1, central layer 1-2 and in the plate 5 formed cavitys 6 (shown in Figure 4) also can inject polyurethane (PU) or polystyrene (EPS) foaming body 7.

In the foregoing description, what central layer 1, panel 2 and base plate 3 adopted is aluminium sheet or steel plate, also can adopt other novel synthetic metal material and other sheet metal, give being coated with earlier on panel 2 and the base plate 3 and coat, it is antiacid to increase, the ability of alkali, and bonding with the upper and lower surface of central layer 1, jointing material can use macromolecular material or other heat-resistant, high strength degree jointing material.
