Abstract
The utility model discloses a steel-plastic composite profile that eliminates the defects such as proneness to heat conduction and poor heat protection in current profile with integral steel line, comprising a steel line and a plastics base material. The model is characterized in that the steel line consists of two pieces of independent steel profiled bars that connect with each other by an I-shaped heat insulation plastic connector or a polyurethane cast heat insulation plastic connector. The utility model separates the integral steel line under the prior art into two independent steel profiled bars, which reduces the processing difficulty and procedures as well. Due to the heat conduction connection of plastic parts, the model has the advantages of low coefficient of heat conduction, good heat protection, energy saving, etc. After combining the corners by sweating soldering, the plastic parts connecting the profiled bars are melted into a whole with high corner strength and could be exclusively used in the industrial and civil building doors and windows.
Description
Technical field
The energy-saving heat preserving composite material that it is discontinuous that the utility model relates to a kind of construction(al)steel plastic door and window section bar, especially steel lining.
Background technology
At present, the steel plastic door and window is anticorrosion with it, anti-wind pressure good, and nonferrous metal resource consumption has replaced early stage common steel sash and aluminum alloy doors and windows less, is widely used in dwelling house and industrial and mining enterprises.Existing composite steel-plastic sections mainly contains disclosed ZL982049838 on October 20th, 1999 " a kind of steel and rigid foamed co-extrusion profile shapes ", it organically combines high mechanical properties and the working of plastics advantage in light weight, erosion-resisting that steel possess, and has remedied the deficiency of steel sash and aluminum window.But its case hardness is low, easily produces cut, because the thermal expansion coefficient difference of steel and plastics is big, steel lining and plastic basis material are easy to generate delamination and ftracture again.Disclosed ZL012269972 on March 13rd, 2002 " environment-friendly type steel skeleton hollow profile shapes " on section bar surface-coated magnetic glazing top layer, has improved the intensity and the ageing resistance on section bar surface, but that steel lining and plastic basis material easily produce the problem of delamination is still unresolved.Aforesaid two kinds of section bar products also have common shortcoming: the one, and steel lining is the integral sealing formula, and manufacturing procedure is many, and heat transmits fast by steel lining, and the door and window heat insulating ability of making is poor, and is not energy-conservation; The 2nd, after the group angle becomes door and window, the steel lining boring, the bight bonding strength is low.Therefore, people expect low, the good heat preservation performance of a kind of thermal conductivity factor, and the steel lining manufacturing is simple, intensity high composite steel-plastic sections in bight behind the group angle.
Summary of the invention
Steel plastic door and window section bar heat insulating ability is poor in order to overcome in the existing background technology field, the low deficiency of intensity behind the group angle, it is discontinuous, low, the good heat preservation performance of thermal conductivity factor that the utility model provides a kind of steel lining, and steel lining inside is the composite steel-plastic sections of real core integral type behind the soldering group angle.
The technical scheme that its technical problem that solves the utility model adopts is: composite steel-plastic sections comprises steel lining and plastic basis material, it is characterized in that steel lining by two independently the steel profile shapes constitute, two steel profile shapes are connected by working of plastics.
Described working of plastics is the heat insulation connection strap that the cross section is " worker " font.
Described working of plastics is the heat insulation connector of cast polyurethane.
Described plastic basis material tool surface-treated layer.
Described surface-treated layer is the PVC weatherability film, tool natural wood grain effect.
Described surface-treated layer is spraying of fluorine charcoal or glazing spraying, the various colors of tool.
The utility model composite steel-plastic sections, steel lining by two independently the steel profile shapes constitute, the steel lining manufacturing is simple, manufacturing procedure reduces, and two profile shapes are connected by the working of plastics of good heat-insulation effect, the thermal conductivity factor of the utility model product is reduced, heat insulating ability improves, behind the soldering group angle, the working of plastics that connects profile shapes is melt into one, and bight intensity height can be widely used in industry and the civil buildings door and window.

The specific embodiment
As shown in Figure 1, 2, the utility model composite steel-plastic sections comprises plastic basis material 1 and by two steel linings of constituting of steel profile shapes 2,3 independently, is connected by working of plastics 4 between the steel profile shapes 2,3.
The utility model steel lining by two independently steel profile shapes 2,3 constitute, make difficulty and reduce greatly than integral sealing formula steel lining, manufacturing procedure reduces.The good effect of heat insulation of working of plastics 4 tools between the steel profile shapes 2,3 improves the heat insulating ability of the utility model product, and energy-saving effect is obvious.Plastic basis material 1 surface forms surface-treated layer 5 after treatment, PVC weatherability film wherein, and tool natural wood grain effect is through spraying of fluorine charcoal or glazing sprayed coating, the various colors of tool.When the utility model product adopts thermal weld mode group angle, but working of plastics 4 hot melts of adjacent profiles be integral, the bonding strength in bight is improved.
Working of plastics 4 among Fig. 1 is heat insulation connection straps that the cross section is " worker " font, it is after being through between the steel profile shapes 2,3 earlier, is made by co-extrusion to the utility model product again.
Working of plastics 4 among Fig. 2 is the heat insulation connectors of cast polyurethane, it is after forming with hot-melt plastic cast between the steel profile shapes 2,3, is made by co-extrusion to the utility model product again.
Fig. 3 to Figure 10 be use the utility model technology produce flat-opening window-leaf material, push-and-pull fan material, push-and-pull frame material and in the sectional view of section bar very, its internal structure is identical with Fig. 1, Fig. 2, also belongs to the claimed scope of the utility model.
In sum, the utility model composite steel-plastic sections will be broken into two independently behind the steel profile shapes between the whole steel lining in the prior art field, and difficulty of processing reduces, and operation reduces.Two steel profile shapes are by the heat insulation connection of working of plastics, make that this product tool thermal conductivity factor is low, good heat preservation performance, advantage such as energy-conservation.Behind the sweat soldering group angle, the working of plastics that connects profile shapes is melt into one, bight intensity height.
