Abstract

The utility model relates to a compound aluminium-plastics window. The frameworks of a window frame and window sashes of the utility model is formed by the assembly of aluminium alloy profiles facing outdoors and plastics profiles facing indoors, wherein each aluminium alloy profile is provided with two swallowtail-shaped grooves along the longitudinal direction thereof; each plastics profile is provided with the corresponding two swallowtail-shaped grooves convexities along the longitudinal direction thereof; the two swallowtail-shaped convexities of the plastics profile are embedded into the two swallowtail-shaped grooves of the aluminium alloy profile when in assembly. Mechanical pressure is exerted on the transverse direction, and the two swallowtail-shaped convexities of the plastics profile are clamped through the transverse deformation of the two swallowtail-shaped groove edges of the aluminium alloy profile; thereby, the aluminium alloy profile is fixedly connected with the plastics profile together. The utility model has the advantages of easy assembly, firm connection, beautiful appearance, easy realization of mechanization production, etc.

Description

Compound aluminium-plastics window

The utility model relates to building doors and windows, refers to a kind of Compound aluminium-plastics window especially.

Along with the economic construction development, building trade development as one of economic construction pillar is very fast, the building doors and windows kind has also been proposed more demand, aluminium, to mould composite door and window frame be the new varieties of developing in recent years, aluminium alloy extrusions has the Material Strength height, be difficult for advantages such as corrosion, good looking appearance, but its coefficient of thermal conductivity height, heat preservation and insulation is relatively poor.Aluminium, moulding built-up sectional material and can solve heat insulation, insulation problem preferably, is new varieties of middle and high shelves building doors and windows, and in the prior art, being connected of aluminium alloy extrusions and plastics plastic is a more scabrous problem.

The purpose of this utility model provides a kind of aluminium, moulds the composite construction of compound door-window section bar, makes its combination easily, is connected firmly good looking appearance.

The purpose of this utility model is achieved through the following technical solutions, a kind of Compound aluminium-plastics window of the present utility model, the framework of its window frame, sash is combined by aluminium alloy extrusions outside the faced chamber and the plastic material in the faced chamber, on the mating face of aluminium alloy extrusions and plastic material, described aluminium alloy extrusions vertically has the groove of double-swallow-tail shape along it, described plastic material vertically has the projection of corresponding double-swallow-tail shape along it, and the double-swallow-tail shape projection of plastic material longitudinally embeds the double-swallow-tail shape groove of aluminium alloy extrusions during combination.

Double-swallow-tail shape projection on the described plastic material mating face is a loose fit with the double-swallow-tail shape groove on the described aluminium alloy extrusions mating face, should projection during combination embed behind this groove in laterally applying mechanical pressure, the lateral yielding who relies on aluminium alloy extrusions dovetail trough rim is recessed clamping of the double-swallow-tail shape of plastic material, thereby aluminium alloy extrusions and plastic material are fixed together.

The utility model has following actively useful effect:

1, two steaming tails of aluminium alloy extrusions and plastic material are protruding, blind mortise connects structure, and its combination is led accurately, easily to straightforward good.

2. be suitable for using the mechanical compression method to make the two dovetail groove side distortion of aluminium alloy extrusions, clamp the two dovetail tangs of plastic material, with the two fixed engagement together, realize the high efficiency production of mechanization, (the facility separate case of exerting pressure is applied for a patent).

3. be connected firmly the bond strength height.

4. the profile after the combination bonds, and screw connection etc. are more attractive in appearance.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the schematic diagram of a kind of construction window of the utility model embodiment.

Fig. 2 is that Fig. 1 is a 2-2 parting view.

Fig. 3 is the 3-3 parting view of Fig. 1.

Fig. 4 is the enlarged detail that aluminium alloy extrusions and plastic material link structure among Fig. 1.

Fig. 5 shows that mechanical compression realizes the schematic diagram that distortion is affixed.

Fig. 1 shows by a fan casement window, form and the embodiment that upward bright building window is arranged of a fan fixed casement window, and Fig. 2, Fig. 3 are respectively its horizontal and longitudinal profile, show its detail of construction.

In Fig. 2, the aluminium alloy extrusions 1 and the PVC plastics plastic 2 of different cross section formed the limit stile 3 of window frame framework respectively, middle stile 4 (see figure 2)s and upper transverse frame 5, transom 6, lower transverse frame 7 (see figure 3)s, and horizontal very 9 (see figure 3)s of upright very 8 (see figure 2)s of sash frame, described window frame adopts the riveted joint of aluminium alloys group corner fitting for four jiaos, single-glass 10 or double-layer glass 11 are housed in the window frame framework, with pressing glass bar 12 fixing formation fixed casement windows 13, single-glass 10 or double-layer glass 11 are housed in sash frame,, on the faying surface of described casement window sash and window window frame neoprene packing bar 15 are housed with pressing glass bar 12 fixing formation casement windows 14.

The utility model relates generally to being connected between aluminium alloys plastic 1 and 2 two kinds of unlike material section bars of plastic material, and its structure sees Fig. 4 for details.

Compound aluminium-plastics window of the present utility model, the framework of its window frame, sash is combined by the plastic material in aluminium alloy extrusions outside the faced chamber 1 and the faced chamber 2, on the mating face of aluminium alloys plastic 1 and plastic material 2, described aluminium alloy extrusions vertically has the groove 16 of double-swallow-tail shape along it, described plastic material vertically has the projection 17 of corresponding double-swallow-tail shape along it, and the swallow-tail form projection 17 of plastic material longitudinally embeds the double-swallow-tail shape groove 16 of aluminium alloy extrusions during combination.Double-swallow-tail shape projection 17 on the described plastic material mating face is a loose fit with the double-swallow-tail shape groove 16 on the described aluminium alloy extrusions mating face, should see Fig. 5 in laterally applying mechanical pressure 18 in these groove 16 backs of projection 17 embeddings during combination, rely on double-swallow-tail shape projection 17 clampings of the lateral yielding on aluminium alloy extrusions double swallow tailed groove limit, thereby aluminium alloy extrusions 1 and plastic material 2 are fixed together plastic material.

During enforcement, also can use the interval, make the double-swallow-tail shape trough rim of aluminium alloy extrusions produce the double-swallow-tail shape projection clamping of lateral yielding, thereby aluminium alloy extrusions and plastic material are fixed together plastic material suitably apart from the method that presses.

In the embodiment of Fig. 2, Fig. 3, several aluminium alloy extrusions and plastic materials that varying cross-section is arranged have only been exemplified, self-evident, the joint construction of combined aluminium alloy profile of the present utility model and plastic material is applicable to that aluminium, the plastic section bar of other any cross section is compound to form various casement windows, sliding sash, aluminium, mould composite gate etc., this manual does not exemplify one by one.
