Abstract

An aluminium-plated steel window (door, or curtain wall) features that the frame of window (door, or curtain wall) is made up of steel and a layer of aluminium film is plated on the surface of steel frame to form a comprehensive anticorrosion coating. Its advantages include special structure design for easy installation and maintenance, good appearance and sealing function aluminium alloy window has, and high strength steel windows has.

Description

A kind of steel sash of aluminium-coating surface

The invention belongs to door, window, the curtain wall field of building.

Along with The development in society and economy, the steel sash of producing according to prior art more and more can not adapt to (containing door, window, curtain wall) needs of modern building at present, and its defective is mainly:

1,, and needs often japanning because corrosion makes its outward appearance not beautiful.

2, because structure design is unreasonable, make glass install and use putty, thus influence attractive in appearance, putty often comes off and cause glass to fall and the difficult maintenance of common people's (refer to not grasp blending putty, standing raw material, smear the people of putty technical ability).

3, poorly sealed, can not adapt to the needs of building energy-saving, air-conditioning.

Existing steel sash because above-mentioned defective, and more and more is extruded the building materials market, and considerable building adopts alumium alloy door and window and for it.But aluminum window costs an arm and a leg, and intensity is low, and is yielding and leak in strong wind and coastal violent typhoon area.More serious is, considerable building is the employing steel sash that reduces cost when building, and the user knocks out steel sash when fitting up and changes aluminum window, thereby causes bigger waste.

The objective of the invention is to overcome the defective of above-mentioned steel sash and change alumium alloy door and window price height, deficiency that intensity is low.

The present invention in order to achieve the above object, adopt steel (shaped steel, sheet material bend, cast steel accessory) to constitute the matrix (window frame, window sash frame) of (weldering, riveting, securing member connection, stationary fit all can be adopted) window for base material, on matrix, plate layer of aluminum metal film (said aluminium then here, be meant that other constituent content is not more than 2% aluminium, generally adopts commercial-purity aluminium.Also can be to contain that zinc 1%～80%, other element are lower than 2%, surplus is the alloy aluminum of aluminium.With hereinafter all identical therewith) further make aluminum metal element and iron-based element of volume between its interface, spread, permeate again, make the external surface oxidation of aluminum metal film, generate Al ₂O ₃Film, thus iron-based material, iron aluminium diffusion layer, Fe formed at steel sash matrix surface (from the inside to surface) ₂Al ₅, aluminum metal layer, Al ₂O ₃The coat structure of layer.[for allumen, the coat structure of steel sash in Fig. 4 is from the inside to surface: 11 iron-based bodies, 12 iron aluminium zinc diffusion layers, 13 Fe ₂Al ₅FeZn ₇FeZn ₁₃FeZn ₂₁, 14 aluminum zinc metal layers, 15 Al ₂O ₃ZnOZn (HO) ₂].

Above-mentioned method of aluminizing metal film on the window matrix can adopt vacuum coating (vacuum evaporation, magnetron sputtering, vacuum ion plating ... all can etc. method, aluminium or pre-processed allumen are as coating materials) method, plating the layer of aluminum metal film through elder generation on the steel sash matrix of purified treatment, and then it is inserted be heated in the heating clamber below 600 ℃, make phase counterdiffusion, infiltration and reaction between aluminium, ferro element.Also the matrix after aluminizing can be placed conventional environment to allow it spread voluntarily, to permeate and to react.

Above-mentioned method of on the window matrix, aluminizing metal film can also adopt hot-dip aluminizing method realize.Be about to window base material and do oil removing, rust cleaning, purification ... Deng pre-treatment, be heated to again about 600 ℃, insert in advance and flood certain hour (1～6 minute) in the molten aluminum liquid (or allumen liquid), propose rapidly, make the certain thickness aluminum metal film of deposition on the steel, the diffusion between the film forming of aluminum metal during hot dipping (perhaps allumen) and aluminium, iron, infiltration are finished simultaneously.

Self-evident both had the alumium alloy door and window beautiful appearance with above-mentioned door, the window that covers the making of aluminum steel material, has the intensity of steel sash and the constructed of aluminium layer that covers on its surface again and have very strong corrosion resistance in moist, acidity, salt mist environment atmosphere.Compare low cost of manufacture with alumium alloy door and window.

Obviously, adopt that above-mentioned to cover the aluminium extruded sections (structurally similar) that the aluminum steel material replaces pandemic plug-type alumium alloy door and window in the society now for the door and window matrix be to realize preferred example of the present invention.

For traditional open-type door and window, the invention provides the example of easy realization as Fig. 1.

Need the door and window of double pane glass for cold district (or air-conditioning, energy-conservation requirement), the invention provides the example (Fig. 1, Fig. 2, Fig. 3 are the cross-section sectional drawings in window frame place) of easy realization as Fig. 2, Fig. 3.

Fig. 1, Fig. 2, Fig. 3 are the primary structure figure that open-type is covered the aluminum steel door and window, wherein: the 1st, window frame, the 2nd, hinge group, the 3rd, window sash frame, the 4th, window glass (or equivalent), the 5th, press strip is installed, the 6th, weather strip (adopts rubber, plastics, cork, leather ... Deng soft material), the 7th, securing member, the 8th, the sealing installed part (adopts rubber, plastics, cork, leather ... Deng soft material), A, B be part 1, part 3, the surface coating structure amplify, Fig. 4 is its enlarged drawing, C is the sash opening direction.

Wherein, part 1,2,3, by above-mentioned vacuum aluminum-coated or hot-dip aluminizing method make to cover aluminium and handle.

Part 5 (can be identical with part 1,3 materials, also other material is as plastics, timber, aluminium etc.), 6,7,8 the I﹠M that is arranged so that window glass become easily, easily and seal.

11 is iron-based bodies, the 12nd among Fig. 4, iron aluminium soluble solids, the 13rd, Fe ₂Al ₅, the 14th, aluminum metal, the 15th, Al ₂O ₃[for allumen, the coat structure of steel sash in Fig. 4 is from the inside to surface: 11 iron-based bodies, 12 iron aluminium zinc diffusion layers, 13 Fe ₂Al ₅FeZn ₇FeZn ₁₃FeZn ₂₁, 14 aluminum zinc metal layers, 15Al ₂O ₃ZnOZn (HO) ₂].

Above-mentioned steel sash is because the Al in the coat structure ₂O ₃Chemical stability, sacrificial action, the Fe of aluminum metal in the chemical attack process ₂Al ₅The comprehensive effect of the resistance to corrosion of itself, make this coat structure in high temperature, humidity, acidity, salt mist environment atmosphere, have very strong corrosion stability, add that covering the aluminum steel window adopts the new structure design, thus make originally cover the aluminum steel window have good looking appearance, intensity height, installation and maintenance convenience, good airproof performance, resistant to rust ability by force, need not second painting, advantage such as low cost.
