Description

Plastic-aluminum combined energy saving window

The utility model relates to building window, is a kind of energy-saving building window with push-and-pull opening ways that utilizes different section bar combinations and constitute specifically.

At present, adopt the building window of section bar splicing structure to mainly contain steel profile window, aluminium extruded sections window, plastic material window and glass fiber reinforced plastic (FRP, glass fiber reinforced plastics) section bar window.Along with improving constantly of public's energy-saving and environmental protection consciousness, also more and more higher to the requirement of the doors and windows of ratio maximum in the loss of building total heat energy.So-called forms are energy-conservation, exactly under the prerequisite that does not influence functional performance, stop or lower the thermal energy exchange of the indoor and outdoor that produces by forms.The major technique of the energy-conservation employing of current form has: the metal window high to coefficient of thermal conductivity separates its frame material, and the middle thermal insulation material that adopts connects, and constitutes on " heat insulation bridge "; Perhaps directly use plastics, the glass-reinforced plastic material of low thermal conductivity to make forms.Though these two kinds of methods can both reduce the thermal energy exchange of indoor and outdoor effectively, reach the forms purpose of energy saving, but also exist defective separately: adopt the internal and external parts of the metal frame material of " heat insulation bridge " to only depend on thermal insulation material to connect, its heat-proof quality and bonding strength mutual restriction are difficult to take into account, and the complex process cost is also very high simultaneously; Though the PVC louver of plastic has than low heat transfer coefficient, its intensity is low, could satisfy the strength and stiffness requirement by adding the heavy section sectional dimension and add steel lining material in inner chamber.Especially at present a large amount of sliding sashs that use, for guaranteeing that certain anti-blast grade has to increase the thickness of sash, could guarantee to have corresponding stiffness, thereby make and be tightly linked relative stressed less window frame with building, the increased in size of also having to double, this will strengthen manufacturing cost undoubtedly.Although adopted these measures, plastic window still is unsuitable for use on the high highrise building of Wind-Pressure Resistance class requirement; Though the glass fiber reinforced plastic forms can reach higher standard on energy-conservation and intensity, also have manufacturing process complexity, the higher deficiency of the cost of raw material.

The purpose of this utility model is the functional cost that makes full use of calorifics, the mechanical characteristic of aluminium, three kinds of materials of plastic and glass steel and take all factors into consideration material, by the optimum organization structure design, a kind of intensity height, life-span length, easy to use are provided, insulation, sound insulation value satisfy the energy-conserving and environment-protective requirement of modern architecture, have the plastic-aluminum combined energy saving window of good economy simultaneously again.

The technical scheme that realizes above-mentioned purpose is: a kind of by window frame that chute is set and the plastic-aluminum combined energy saving window formed with the sliding window sash of its configuration, its window frame is by the empty stomach aluminium extruded sections and plastic material is compound constitutes, aluminium extruded sections places the outside, plastic material places the inboard, and the two is by filled heat insulating material in the cavity that is connected and constitutes after compound on the chimeric limit of corresponding setting; Its sash by empty stomach glass fiber reinforced plastic shapes and setting-in thereon card article and constitute through the glass of this card article assembling.

The technical solution of the utility model also comprises: form the plastic material of window frame and the glass fiber reinforced plastic shapes of composition sash and be provided with groove, be equipped with weather strip in corresponding grooves; Between the glass of forming inboard itself and insert of glass rib on the glass fiber reinforced plastic shapes of sash, be provided with sealant tape.

The utility model compared with prior art has following advantage:

1, window frame adopts aluminium extruded sections and plastic material to be incorporated in the structure of filled heat insulating material between the two again, its aluminium extruded sections is as strength member, plastic material is as building blocks of function, filler is as the thermal insulation layer, given full play to three kinds of materials characteristic separately, when guaranteeing the window structure function, make it have excellent heat insulation property, processing performance and the ratio of performance to price.

2, sash adopts the glass fiber reinforced plastic drawing and extruding section bar to make, the characteristics that its light weight is high-strength, coefficient of thermal conductivity is low have been made full use of, under the prerequisite that guarantees sash mechanics, thermal property, make the thickness of section bar reduce 30%, greatly reduce cost of production, also allow some leeway for reducing the window frame size than PVC section bar.

3, comprehensively adopt multiple spot sealing, compound heat-insulation, reduce technical measures such as thermal exposure, make forms have energy-conservation, environmental protection characteristics such as good airtight, insulation, sound insulation.Machine simulates as calculated, and comparable conventional window body segment can reach as high as 80% (low radiation hollow glass is installed) more than 60% (installation hollow glass).

Accompanying drawing 1 is this plastic-aluminum combined energy saving window overall structure front view;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is the B-B sectional drawing of Fig. 1.

The utility model is described in further detail below in conjunction with drawings and Examples:

Provide as accompanying drawing 1, this plastic-aluminum combined energy saving window is formed by the window frame 1 that chute is set with the sliding window sash 2 of its phase configuration.As shown in accompanying drawing 2, Fig. 3, its window frame 1 is incorporated in filling foamed plastics heat insulating material 4 constitutes in the cavity after compound section bar again by empty stomach aluminium extruded sections 3 and plastic material 5 to carry out mechanical connection through joint angle and is assemblied to form.During assembling its aluminium extruded sections place the outside, in plastic material places then.Window sash frame and setting-in plastics card article 7 thereon and glass 8 formations of assembling that sash 2 adopts glass fiber reinforced plastic drawing and extruding section bar 6 to connect to form through mechanical angle through card article.When being installed, glass sealant tape 9 is set in the glass rib inboard of glass fiber reinforced plastic shapes 6.Sash 2 is installed on the window frame 1 by the chute that is provided with on the plastic material 5, and its face place that is slidingly matched mutually is provided with dovetail groove on the glass fiber reinforced plastic shapes of the plastic material of window frame and sash, is equipped with weather strip 11 in corresponding grooves.As shown in Figure 2, below the glass fiber reinforced plastic shapes 6 that constitutes sash 2 lower frame bodies, can assemble two slide blocks made from wear-resistant plastic 12 and form friction pair with glide path, the sliding-frictional resistance when being used to reduce the sash unlatching; On the glass fiber reinforced plastic shapes 6 of lower frame body, cushion block 10 is set, is used to avoid glass directly to contact, reduce the influence that extraneous factor produces forms glass with the sash lower frame body.As shown in Figure 3, the sealing profile 13,14 that cooperatively interacts can be set on the facade that interior outer leaf 2 combines, the tightness when being used for strengthening sash and closing.
