The sound insulation color corrugated sheet steel
[technical field]
The utility model relates to color painted steel strip, the well behaved chromatic steel sandwich plate of especially a kind of fire-proof sound insulation.
[background technology]
The modern architecture moulding is more and more novel unique, meanwhile also more harsh to the performance of roofing materials, both required building materials specious, durable again light, be convenient to on-the-spot the installation, from heavy and light, intensity height, excellent waterproof, sound insulation, anti-seismic performance become the constructional materials that present use has a large capacity and a wide range to profiled sheet with it.Chromatic steel sandwich plate is a kind of MULTILAYER COMPOSITE steel plate of extensive use, has good heat-insulating property, present stage sandwiched plate also have a lot of defectives, though as EPS plate good heat insulation, but its inflammable fire.Thus with rock wool as the substituting of sandwich place, but its cost is high.
[summary of the invention]
The utility model provides that a kind of price is low, the chromatic steel sandwich plate of fire-proof sound insulation function admirable.
The technical scheme that the prior art problem that solves the utility model is adopted is: a kind of sound insulation color corrugated sheet steel, comprise the die mould flaggy of enameling, following colored die mould flaggy, and about bound edge, the middle container cavity that forms, it is characterized in that: the bonding rock wool layer of described container cavity wall, it is trapezoidal rib that described colored die mould flaggy external surface is formed with the cross section, on the rib of this sound insulation color corrugated sheet steel one side bloop is set.
The beneficial effects of the utility model: chromatic steel sandwich plate adopts rock wool to fill, and laminboard layer is not solid but adopts the hollow form of the bonding rock wool layer of wall that saved the rock wool use amount, and rock wool layer is thinner, process is convenient.Simultaneously, on the rib of this sound insulation color corrugated sheet steel one side bloop is set, sound runs into the sound insulation color corrugated sheet steel and will be absorbed by this bloop, has strengthened the function of sound insulation.
[description of drawings]
Fig. 1 is the structural representation of the utility model sound insulation color corrugated sheet steel;
[specific embodiment]
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail:
As shown in Figure 1, a kind of sound insulation color corrugated sheet steel, comprise the die mould flaggy 1 of enameling, following colored die mould flaggy, and about bound edge 2, the middle container cavity that forms, the bonding rock wool layer 3 of container cavity wall, it is trapezoidal rib 4 that described colored die mould flaggy external surface is formed with the cross section, and two row's bloops are set on the rib of this sound insulation color corrugated sheet steel one side.The draw-in groove that bound edge one side makes things convenient for contour plate to install in addition.
The beneficial effects of the utility model: chromatic steel sandwich plate adopts rock wool to fill, and laminboard layer is not solid but adopts the hollow form of the bonding rock wool layer of wall that saved the rock wool use amount, and rock wool layer is thinner, process is convenient. Simultaneously, on the rib of this sound insulation color corrugated sheet steel one side bloop is set, sound runs into the sound insulation color corrugated sheet steel and will be absorbed by this bloop, has strengthened the function of sound insulation.
The utility model is applicable to coated plate, Al-Mg-Mn plate and aluminium alloy plate too.
