Abstract

The utility model relates to an aluminum plastic compound window, which is high strength weld corner aluminum plastic compound windows comprising the window sash or window frame. In the hollow cavity of each profile edge at the angle joint of the two edges of the window sash or the window frame, a section of plastic plug-in is inserted inward aligned with the end part. The joint part of the profiles is filled with the plug-in and the outer end of the plug-in is aligned with the outlet of the profiles. Thus, when the two angles of the window sash or the window frame is butt welding, the contact area is enlarged and the joint strength is enhanced. Thus the welding quality is ensured and the requirement for use is met. The welding site of the angle joint of the window sash or the window frame is designed with the structure of filling up the cavity of the profile which realizes the purpose of meeting the requirement for use through making some simple modifications to the existing profile. The safe and reliable utility model has simple structure, reasonable design and lower costs.

Description

High strength leg aluminum plastic compound window

Technical field

The utility model relates to a kind of aluminum plastic compound window, i.e. high strength leg aluminum plastic compound window.

Background technology

In prior art, emerging aluminum plastic compound window is to adopt 45 degree lap fillet weldings to be connected into frame plastic material, then aluminium alloy extrusions is embedded on the plastics sash or window frame that assembles, its shortcoming is if also adopt common plastic material, bonding strength in adjacent framework junction is relatively poor, fragile; If adopt special section bar, cost height then.

The utility model content

The purpose of this utility model is to provide a kind of under the situation that does not change plastic material material and structure at above-mentioned deficiency, improves the high strength leg aluminum plastic compound window of aluminum plastic compound window angle bonding strength.

Technical solution of the present utility model is: high strength leg aluminum plastic compound window comprises sash or window frame, in the section bar cavity of every limit of sash or window frame both sides corner connection place, inwardly is plugged with one section plastic plug by concordant with the end.Because the section bar junction is filled with plug-in unit and the plug-in unit outer end is concordant with the section bar mouth, when sash or window frame two angle-butt welds, promptly increased contact area and increased bonding strength again like this, guaranteed welding quality, satisfy instructions for use.

Have multiplely in section bar cavity plug-in part mode, as by at all section bar cavity interpolation connectors, but processing charges and materials height are inadvisable.Being exactly in addition in a plurality of section bar cavitys, under the situation that guarantees bonding strength, pegging graft selectively, is preferred version.So the grafting principle is at the cavity interpolation connector of section bar near the stressed strong point.

The utility model has the advantages that: connect weld at sash or window frame angle, adopt the structure design of filling up the section bar cavity, make existing section bar is improved a little, just can satisfy instructions for use, simple in structure, reasonable in design, with low cost, safe and reliable.

Below in conjunction with accompanying drawing the utility model is described in further detail.

2,3 is plugged near in the section bar cavity of the stressed strong point.

Referring to Fig. 4, high strength leg aluminum plastic compound window comprises window frame 2.

Referring to Fig. 5, be the enlarged drawing of window frame 2 both sides corner connections place.In the section bar cavity of every limit,, weld along diagonal then by the concordant one section plastic plug 4,5 that inwardly is plugged with the

end.Plastic plug

2,3 is the hard PVC moulding, and an end is processed into miter angle, inserts in the window frame 2 section bar die cavities, after wood screw is fixing, carries out the miter angle welding with the principal mode material.

Referring to Fig. 6, be window frame 2 transverse section of section material schematic diagrames.Plastic plug 4,5 is plugged near in the section bar cavity of the stressed strong point.

Claims

1, a kind of high strength leg aluminum plastic compound window, comprise sash (1) or window frame (2), it is characterized in that in every limit section bar cavity of sash (1) or window frame (2) both sides corner connection place, by concordant one section plastic plug (2), (3), (4) or (5) of inwardly being plugged with the end.

2,, it is characterized in that plastic plug (2), (3), (4) or (5) are plugged near in the section bar cavity of the stressed strong point according to the described high strength leg of claim 1 aluminum plastic compound window.
