CN2825891Y - Metal-plastic composite section bar - Google Patents

Abstract

The utility model relates to a metal-plastic composite section bar, a main body of which is made of solid plastics and the external surface is partly or entirely covered by an aluminum layer or a stainless steel layer. Because the solid section bar has high strength, the thickness of the metal layer can be decreased and metal consumption amount can be reduced. In addition, because of the solid structure, all screw threads of mounting screws can be forced and firmness degree is obviously raised.

Description

The metal-plastic composite material

Technical field:

The utility model relates to architectural shape, particularly a kind of metal-plastic composite section.

Background technology:

Existing section bar is aluminium alloy extrusions and steel plastic section bar, generally all makes hollow type, is guaranteed strength, and aluminium alloy extrusions need have enough wall thickness, and the consumption of aluminium is big; The steel plastic section bar then needs the steel plate bar as reinforcing rib, processed complex, and the plastics long term exposure is easily aging in the sun, influences application life.In addition owing to be hollow structure, the screw that connects during installation can only be in the section bar wall thickness range a few circle screw threads stressed, fastness is installed and is used in influence.

Summary of the invention:

The purpose of this utility model provides that a kind of cost is low, intensity is high, the metal-plastic composite material of long service life.

The solid plastic that is characterised in that of the present utility model constitutes the section bar main body, its local or whole external surface covered with metal layer.

The utility model constitutes the section bar main body with solid plastic, and external surface covers aluminium lamination or stainless steel layer, because solid profile has higher intensity, so metal level can reduce thickness, reduces expensive day by day metal consumption.In addition, because solid construction, all screw threads of mounting screw are all force-applied, and firmness obviously improves.

Description of drawings:

Fig. 1 is the local sectional view that covers metal level embodiment of window frame profile.

Fig. 2 is the sash profile sectional view that is used with Fig. 1 section bar.

Fig. 3 is the sectional view of the whole covered with metal layer embodiment of window frame profile.

Fig. 4 is the sash profile sectional view that is used with Fig. 3 section bar.

The specific embodiment:

Embodiment 1:

With reference to Fig. 1, Fig. 2, at first with the engineering plastics pressure injection or be extruded into the solid profile main body 1 of required form, adopt the copper clad plate technology with aluminium skin or the stainless steel sheet| 2 deposited local external surfaces of section bar main body that are connected on then, the position that people are difficult for seeing under the user mode of back promptly is installed need not to apply metal level.

Embodiment 2:

With reference to Fig. 3, Fig. 4, at first routinely aluminium alloys or stainless steel are pulled into the thin section bar formation metal external coating 2 of wall thickness, then to the plastics of inner chamber pressure injection melting state, solidify the back and constitute solid plastic section bar main body 1; Also but pressure injection is gone into the solid foamed plastic layer of the adiabatic filling of fluorinefree polyurethane expanded material formation.Mark 3 is the screw position groove among the figure, and 4 is the wool top mounting groove, and 5 is glass installation groove.

Claims (1)

1, a kind of metal-plastic composite material is characterized in that solid plastic constitutes section bar main body (1), its local or whole external surface covered with metal layer (2).
