Background

The bridge-cut-off aluminum door and window is an energy-saving heat-insulation door and window provided with a plastic bridge cut-off with excellent heat-insulation performance between an inner structural member and an outer structural member of an aluminum alloy door and window, and is widely applied to the field of buildings. The outer side and the inner side of the bridge-cut-off aluminum door and window are aluminum alloy sections, inner and outer structural members of the aluminum alloy sections clamp the hollow glass, and the aluminum sections are connected through plastic bridge-cut-off to block heat conduction between the inner and outer structural members of the aluminum alloy sections.

For example, CN 113802955A discloses an energy-saving bridge-cut-off aluminum door window, which includes a window frame assembly, where the window frame assembly includes a first window frame, a second window frame, and a first connecting member for connecting the first window frame and the second window frame, and both the inside of the first window frame and the inside of the second window frame are hollow structures and form a first vacuum cavity; the fan frame assembly comprises a first fan frame, a second fan frame and a second connecting piece for connecting the first fan frame and the second fan frame, the first fan frame is rotatably connected to the first window frame, and the interior of the first fan frame and the interior of the second fan frame are both hollow structures and form a second vacuum cavity; the glass assembly comprises a first glass plate and a second glass plate, the first glass plate and the second glass plate are fixedly arranged between the first sash frame and the second sash frame and are parallel to each other, and a third vacuum cavity is formed between the first glass plate and the second glass plate. This prior art separates heat and noise through making the bridge cut-off aluminium door and window form the vacuum negative pressure region of large tracts of land in, has thermal-insulated noise reduction effect excellent characteristics.

However, for the door and window structure in the civil field, the space structure of the bridge-cut-off aluminum door and window cannot be kept in a vacuum state for years, once the vacuum between the structures fails, the space is filled with air, the air can form convection inside the structure, and heat is transferred between the inside and the outside of the door and window, so that the heat insulation effect of the bridge-cut-off structure is reduced.

The inner suspension film door and window is an energy-saving and heat-insulating door and window with an inner suspension film arranged in hollow glass of the door and window, and has the characteristics of light weight and excellent energy-saving and heat-insulating effects. For example, CN 106968564A discloses a double-suspension-film phase-change heat-insulating hollow glass, which comprises an outer frame and an inner frame, wherein guide plates of two push-pull frames of the inner frame are respectively embedded into a left guide groove and a right guide groove of a reference frame, a compression spring is arranged between the guide plates and the guide grooves, plastic caps for fixing membranes are arranged in clamping grooves of the two push-pull frames, the plastic caps are dumbbell-shaped, two flange guide rails in the clamping grooves clamp the waist of the plastic caps, the double-suspension-film inner frame is embedded into a central groove of the outer frame, the double-suspension-film inner frame is wrapped by two ladder-shaped cavities of the outer frame, the reference frame and the outer frame are connected and positioned by screws and nuts, inner piece glass and outer piece glass are bonded on two sides of the outer frame, and a double-channel sealing structure is formed by hot-melt butyl adhesive and structural adhesive, thereby forming a hollow glass with double-suspension films and four peripheral parts having a phase-change heat-insulating function.

Interior membrane door and window hangs membrane through the interior membrane that hangs that increases plastics and make in cavity glass's inner chamber, isolates into a plurality of mutually independent spaces with cavity glass's inner chamber to the air in making each space can't realize the convection current, thereby can obtain the effect of isolated heat transfer. Therefore, if the inner suspension film is arranged between the hollow glass of the existing bridge-cut-off aluminum door window, the defects of vacuum failure and reduced heat insulation effect caused by internal air circulation convection can be overcome to a certain extent.

However, it is not easy to install the inner suspension film between the hollow glasses of the aluminum door/window. Because the shapes of the inner and outer structural members of the bridge-cut-off aluminum door and window are complex and the installation is difficult, the hollow glass needs to be assembled into an independent component in advance in a factory and then transported to the site to be installed between the bridge-cut-off aluminum profiles. Therefore, the internal suspension film cannot be temporarily set into the insulating glass at the installation site. If the inner suspension membrane is assembled inside the hollow glass in a factory, the two sides of the glass need to be firmly bonded into a whole, so that the two sides of the glass are prevented from being separated and dislocated in the transportation process. In addition, because the inner suspension film is a flexible plastic film, the inner suspension film can not be contacted with glass only by keeping the inner suspension film in a tight state, and the inner suspension film cannot be folded to influence the light penetrability. The two sides of the glass are firmly bonded, the middle inner suspension film is ensured to be in a tensioning state, a heat transfer path does not exist between the two sides of the glass, and great technical difficulty exists.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

As shown in fig. 1, the present application provides a bridge-cut-off aluminum inner suspension film door and window, which comprises an outer profile frame 10 and an inner profile frame 20 connected into a whole through a first heat insulation bridge cut-off 40, wherein a hollow glass assembly 30 is arranged between the outer profile frame 10 and the inner profile frame 20.

In one embodiment, as shown in the figures, the bridge cut-off aluminum inner-suspended membrane door and window of the present application may further include an inner molding 50, the inner molding 50 is snap-coupled to the top of the inner profile frame 20, and the hollow glass assembly 30, which is pre-bonded in one piece, is disposed in a concave space surrounded by the outer profile frame 10, the first insulating bridge cut-off 40, the inner profile frame 20 and the inner molding 50. The first insulating bridge-cut 40 may be a bridge-cut preform of a commercially available nylon material, such as PA66 nylon. In the illustrated embodiment, two first insulating bridges 40 are provided between the outer profile frame 10 and the inner profile frame 20. The insulating glass unit 30 includes two layers of insulating glass 1 arranged in parallel, and at least one inner suspension film 2 is disposed in a cavity between the two layers of glass 1, which will be described in further detail later.

During installation, the outer profile frame 10 and the inner profile frame 20 are connected into a whole through the first thermal insulation bridge 40, and then are buried in the wall opening and fixed with the wall. Then, the hollow glass assembly 30 which is bonded into a whole in advance is horizontally pushed from the inner side and installed above the first heat insulation bridge-cut-off 40, finally, the inner side bead 50 is connected to the top of the inner profile frame 20 in a buckling mode, the outer profile frame 10 and the inner side bead 50 respectively abut against the outer sides of the outer layer glass and the inner layer glass of the hollow glass assembly 30, and the hollow glass assembly 30 is clamped and fixed.

In the embodiment shown, the outer profile frame 10 has an outer profile flange 101 abutting against the outer side of the outer pane of the insulating glass unit 30 for blocking the insulating glass unit 30 by the outer profile flange 101 when mounted from the inside. For sealing, a first sealant strip 102 is provided between the outer profile flange 101 and the outer pane, and a second sealant strip 502 is provided between the inner bead 50 and the outer side of the inner pane of the hollow glass subassembly 30. In order to avoid the indoor warm and humid air from dewing and invading into the aluminum profile to cause corrosion, a drying strip 501 is arranged in the hollow cavity of the inner side strip 50. Since the inner molding 50 is snap-connected to the top of the inner frame 20, the inner molding 50 can be easily removed to facilitate disassembly and maintenance of the hollow glass module 30, and the drying strip 501 can be easily removed and replaced periodically.

To facilitate the flat push installation of the insulating glazing units 30 from the inside over the first insulating bridge 40, the top height of the inner profile frame 20 preferably does not exceed the highest point of the first insulating bridge 40. The advantage of design like this is, when the installation, need not on the scene at the top of first thermal-insulated bridge cut-off 40 add the cushion, therefore does not need to reserve great activity space between the side of cavity glass subassembly 30 and the first thermal-insulated bridge cut-off 40, has reduced the structure gap, has improved sealed heat-proof quality.

In particular, since it is difficult to ensure that the installation units or persons are completely installed according to the specifications, if the movement space of the reserved gap is too large, the installation units or persons may fill the gap with substances such as expansion glue for trouble saving, and as a result, after the door and window are installed, the hollow glass assembly 30 is completely stuck and cannot be detached from the concave space surrounded by the outer profile frame 10, the first heat insulation bridge-cut-off 40, the inner profile frame 20 and the inner side bead 50, and the whole bridge-cut-off aluminum door and window becomes a disposable structure, and the possibility of repairing and replacing components in the later period is completely lost. The present application is designed specifically so that the height of the top of the inner profile frame 20 does not exceed the highest point of the first insulating bridge-breaks 40, which can reduce the anticipated gap to the minimum state for flat-pushing installation, eliminate the possibility of irregular installation, and provide convenience for subsequent replacement and maintenance of the insulating glass unit 30, which is greatly related to the inner suspended membrane in the insulating glass unit 30 of the present application, as will be further explained later.

Fig. 2 shows an exploded view of an insulating glass unit 30 according to an embodiment of the present application, and as mentioned above, the insulating glass unit 30 of the present application comprises two layers of hollow glass 1 arranged in parallel, and at least one layer of inner suspension film 2 is arranged in the cavity between the two layers of glass 1, however, it should be understood by those skilled in the art that two or more layers of inner suspension films 2 may be arranged between the two layers of glass 1 as required. The inner suspension film 2 is made of a plastic film with good heat-resistant and insulating effects, and needs to be tensioned between hollow glasses to keep light rays transmitted in parallel to avoid visual deformation.

In order to facilitate the assembly operation of the hollow glass assembly 30, the inner suspension film 2 is arranged in the tensioning frame 3 in a tensioning state, and the tensioning frame 3 and the inner suspension film 2 in the tensioning state can be installed between the two layers of glass 1 as an independent component, so that the problem of field tensioning of the inner suspension film 2 does not need to be considered when the bridge-cut-off aluminum inner suspension film door window is installed, and the installation complexity is reduced. For ease of understanding, the inner suspended membrane 2 and the tensioning structure in fig. 2, which is originally mounted inside the tensioning frame 3, are shown deliberately disassembled from the tensioning frame 3, the tensioning frame 3 itself not being disassembled.

In addition, if the problem of excessive looseness or aged discoloration of the inner suspension membrane 2 occurs, it is necessary to consider the problem of replacement or repair by detaching the inner suspension membrane 2 from the hollow glass assembly 30, which is a problem to be considered and solved when the convenience of subsequent replacement and maintenance of the hollow glass assembly 30 is required as explained above. This problem does not exist in the existing bridge-cut-off aluminum doors and windows, and thus, the problem of considering the disassembly and replacement of partial structures does not exist. And because the not good problem of durability of plastic film, just have to consider the problem of maintenance change in the interior membrane door and window of hanging, consequently this application sets up the tensioning frame 3 of independent structure, very conveniently just can dismantle tensioning frame 3 together with interior membrane 2 wherein.

Further, in the illustrated embodiment, both sides of the tension frame 3 may be bonded between the two sheets of glass 1 by spacer bars 4. For example, the spacer 4 may be an existing composite butyl aluminum spacer, butyl rubber is provided on both sides of the spacer 4 for adhesion, and a molecular sieve for adsorbing water vapor is provided in a hollow structure inside the spacer 4 (fig. 1). The shown inner suspension film door and window is only provided with one layer of inner suspension film 2, and can be deformed into a structure with two or more layers of inner suspension films 2 by additionally arranging the tensioning frame 3 according to needs.

Further, the operation of tensioning the inner suspension membrane in the prior art is cumbersome, requires four sides of the inner suspension membrane to be clamped on a plurality of elastic elements respectively during installation, and requires local repeated adjustment of the tensioning force in order to prevent wrinkling. In addition, interior membrane is repeated expend with heat and contract with cold in the long-term use, and the tensile force difference can lead to the film to local position extrusion formation fold, and this can influence door and window's permeability, and the outdoor scenery of observation can produce visual deformation because of the refraction.

In order to solve the above problem, as shown in fig. 2 to 3, four sides of the inner suspension film 2 of the present application are wound around four reels 21, respectively, and both ends of the four reels 21 are mounted inside the tension frame 3 through elastic tensioners 5, respectively.

In one illustrated embodiment, in order to facilitate the exposure of both ends of the winding shaft 21 while tensioning the inner suspension film 2, the inner suspension film 2 is rectangular with four corners cut off so that the width of the four sides of the inner suspension film 2 becomes narrower as they approach the edge positions, and thus the winding thickness of the inner suspension film 2 on the winding shaft 21 becomes thicker as it approaches the middle of the winding shaft 21 and becomes thinner as it approaches both ends of the winding shaft 21 when wound on the winding shaft 21. That is, the inner suspension film 2 wound around the bobbin 21 is formed into a spindle shape having a thick middle and thin ends. Therefore, as the inner suspension film 2 is tightly wound on the winding shaft 21, the tension of the middle position of the inner suspension film 2 is gradually greater than that of the corner positions, and the stretching and loosening of the film caused by the thermal expansion of the middle suspended inner suspension film can be counteracted. Meanwhile, the winding edge of the inner suspension film 2 tends to extend towards the two thinner ends, thereby naturally eliminating the phenomenon that the film is locally extruded to generate wrinkles.

In order to facilitate the winding of the inner suspension film 2 by the winding shaft 21 to generate a uniform tension, it is preferable that the section of the middle portion of the winding shaft 21 for winding the inner suspension film 2 is circular. In addition, in order to facilitate that the tension force connected to the elastic tension device 5 is not loosened after the tension, the cross section of the reel 21 for connecting both ends of the elastic tension device 5 is square, so that the reel 21 is not easily rotated.

Fig. 4-5 show the detailed structure of the elastic tensioning device for the bridge-cut-off aluminum inner suspension membrane door and window. As shown in the figure, the elastic tensioning device 5 includes a fixed base 51, a telescopic clamping seat 52 is disposed below the fixed base 51, and a spring 53 is disposed between the telescopic clamping seat 52 and the fixed base 51. Two springs 53 are arranged side by side between the telescopic clamping seat 52 and the fixed base 51 for force balance. The end of the reel 21 is hung on the telescopic clamp 52 and the inner suspension membrane 2 is tensioned by a spring 53.

Furthermore, the fixed base 51 may be formed by integrally cutting and bending a metal plate, and includes a fixed top plate 511 that abuts against the first end of the spring 53, two sides of the fixed top plate 511 are respectively bent to form a guide plate 512, and the bottom of the guide plate 512 is bent to form a mounting plate 513; a positioning screw hole 5111 for positioning the spring 53 is formed on the fixed top plate 511; the mounting plate 513 is formed with a mounting screw hole 5131, and the entire elastic tension device 5 can be mounted inside the tension frame 3 by a screw inserted into the mounting screw hole 5131.

Two positioning screw holes 5111 are provided on the fixed top plate 511 corresponding to the number of the springs 53, and one positioning screw 5112 is provided in each positioning screw hole 5111. After the set screw 5112 passes through the set screw hole 5111, the end of the set screw passes through the end of the spring 53, so that the spring 53 will not break away from the set screw 5112 and fail during compression.

The telescopic clamping seat 52 can also be formed by integrally cutting and bending a metal plate, and comprises a movable top plate 521 which abuts against the second end of the spring 53, wherein the bottom of the movable top plate 521 is bent towards one side of the fixed top plate 511 to form a telescopic guide plate 522, the telescopic guide plate 522 passes through the tail end of a guide hole 5113 at the bottom of the fixed top plate 511 to be bent upwards to form a hanging plate 523, and a clip hook plate 524 is formed at the tail end of the hanging plate 523; the end of the square section of the reel 21 is unrotatably caught in the concave space formed by the telescopic guide plate 522, the hanging plate 523, and the hook plate 524.

The guide plate 512 is formed with a guide groove 5121, and the movable top plate 521 is formed at both ends thereof with protrusions 5211, respectively, and the protrusions 5211 are inserted into the guide groove 5121 and can move back and forth along the guide groove 5121.

When the elastic tensioning device 5 is assembled, the telescopic clamping seat 52 deflects by a certain angle, the protruding part 5211 is inserted into the guide groove 5121, then the telescopic clamping seat 52 is corrected, the spring 53 is placed between the telescopic clamping seat 52 and the fixed base 51, and finally the positioning screw 5112 is screwed to fix the position of the spring 53. After the fixed base 51 is installed on the tension frame 3, the telescopic clamping seat 52 is limited below the fixed base 51 through the guide groove 5121 and the guide opening 5113, and the telescopic clamping seat 52 can only move in parallel along the guide groove 5121, so that a stable elastic action can be provided for the end of the reel 21.

The end of the scroll 21 is of a square section structure, and can be clamped in concave spaces of the telescopic guide plate 522, the hanging plate 523 and the clip hook plate 524 without rotating, the clamping structure is simple and effective, and the operation is very convenient. The elastic tensioning device 5 is simple in structure and high in operation reliability, the compression force of the spring 53 is converted into the tensile elastic force, the elastic continuous effect of the whole structure is extremely high, and the elastic tensioning device can be used in a maintenance-free operation mode for life.

This application is through coiling four limits of interior membrane on four spools respectively, can obtain bigger tensile force at the middle part of interior membrane that hangs, has offset interior membrane that hangs relaxation of being heated, has eliminated the fold through coiling naturally simultaneously, therefore when installing on the tensioning frame, only need the both ends of tensioning spool, need not adjust tensile force one by one to every point position of the periphery of interior membrane that hangs, greatly reduced the complexity of tensioning operation.

Further, as shown in fig. 1 and 3, the tension frame 3 includes a first frame 31 and a second frame 32 disposed on both sides of the inner suspension film 2, the elastic tension device 5 is disposed inside a cavity formed by connecting the first frame 31 and the second frame 32, and the tension frame 3 is connected to the first frame 31 and the second frame 32 to form a closed annular cavity, so as to isolate air and avoid heat transfer caused by air convection.

As can be seen from the cross-sectional view shown in fig. 1, the first frame body 31 and the second frame body 32 have the same structure, and are integrally connected to each other by the second thermal insulating bridge 401. As can be seen from the exploded perspective view shown in fig. 3, the first frame 31 and the second frame 32 may be formed by splicing four section bars, and two corresponding section bars of the first frame 31 and the second frame 32 are connected by a second thermal insulation bridge 401 to insulate heat transfer between the two frame bodies.

The four profiles of the first frame 31 and the second frame 32 may be connected into a whole by welding or bonding, or two adjacent profiles may be connected into a whole by screws through the corner connecting pieces 6. At this time, the corner connecting piece 6 not only connects a set of two elastic tensioning devices 5 at the corner position into a whole (connected into a whole by welding or screwing, etc.), but also can connect two section bars into a whole. In the embodiment shown in fig. 3, the elastic tensioning means 5 are arranged mounted on the first frame 31. Of course, it will be understood by those skilled in the art that in an embodiment not shown, the elastic tensioning device 5 may also be arranged mounted on the second frame 32.

In the illustrated embodiment, two elastic tensioning devices 5 are provided for each reel 21, so that a total of eight elastic tensioning devices 5 are provided inside the first frame 31 and the second frame 32, and only six elastic tensioning devices 5 are shown in fig. 2 due to the view angle blocking. Two elastic tensioning devices 5 are arranged in a group and are connected into a whole through a corner connecting piece 6 and are arranged at the corner position of the tensioning frame 3 together.

As shown in fig. 1 to 3, the first frame body 31 and the second frame body 32 respectively have annular flanges 311 at opposite positions, and in order to improve the isolation effect, in the illustrated embodiment, an elastic sealing strip 402 is mounted on the top of the annular flange 311 abutting against the inner suspension membrane 2. Still further, in the embodiment shown in fig. 1, the height of the elastic sealing strip 402 is just enough to keep the suspended membrane 2 in a flat tensioned state, and the suspended membrane 2 is not lifted by the elastic sealing strip 402. In another embodiment, not shown, the height of the elastic sealing strip 402 may be varied, for example, the height of the elastic sealing strip 402 on one side may be slightly higher, so that the inner suspension membrane 2 is lifted by the elastic sealing strip 402 to form a bending angle after being installed, thereby increasing the tensioning degree of the inner suspension membrane 2 and improving the sealing effect of the elastic sealing strip 402 against the inner suspension membrane 2.

Since the tension frame 3 and the inner suspension film 2 therein are installed as a separate component between the two glass sheets 1, it means that the first frame body 31 and the second frame body 32 of the tension frame 3 are respectively bonded to one glass sheet through a spacer 4. Since one piece of glass has a very large weight, when the hollow glass module 30 is transported, one side of the glass needs to be sucked by the suction cup, and at this time, it is necessary to ensure that the first frame 31 and the second frame 32 are connected very firmly. It may be not very firm to connect the first frame 31 and the second frame 32 by the second thermal bridge 401 made of nylon material alone, for example, when the hollow glass assembly 30 is lifted by the suction cup, the second thermal bridge 401 may be separated from the clamping groove of the frame, and when the hollow glass assembly 30 is laid flat, the second thermal bridge 401 may be broken due to the excessive pressure. Although the first frame 31 and the second frame 32 can be connected into a whole by conventional metal connecting pieces, such connection strength is very high, but heat can be directly transferred between the two frames connected by metal, and the bridge-cut aluminum profile arranged on the outer side has little effect, which is a contradiction existing in combining the existing bridge-cut aluminum profile and the internal suspension membrane structure.

To solve this contradiction, in a specific embodiment of the present application, the first frame body 31 and the second frame body 32 are connected into a whole through the second thermal insulation bridge 401 to insulate the heat transfer, and at the same time, the lateral sides of the two layers of glass 1 are further provided with the adhesive beads 60, and the adhesive beads 60 adhere the two layers of glass 1, and the spacer 4 therein, and the sides of the first frame body 31, the second frame body 32, and the second thermal insulation bridge 401 of the tensioning frame into a whole. In this way, the two sheets of glass 1 are actually bonded together by the adhesive bead 60, and although it appears that the bonding width between the side edges of the two sheets of glass 1 and the adhesive bead 60 is small, the spacer 4 and the first frame 31 or the second frame 32 are sequentially bonded to the peripheral surface of the glass 1, so that the bonding width of the side edges is greatly widened. For example, if the thickness of the single glass sheet 1 is 5 mm, the thickness of the spacer 4 is 9 mm, the side bonding thickness of the frame body is 10 mm, and the side bonding thickness of the second insulating bridge-cut 401 is 12 mm, the bonding width of the entire side of the hollow glass assembly 30 to the bonding bead 60 can be up to 60 mm at maximum, which is strong enough for the bonding bead 60 made of nylon or rubber bonded by using a high strength adhesive. The adhesive bead 60 shown in fig. 2 and 3 is a split structure corresponding to four side frames, and the adhesive bead 60 may be in the form of a whole continuous strip, if necessary, and only a joint (not shown) is formed at the butted head portion.

Further, as shown in one embodiment shown in fig. 1 to 3, the adhesive bead 60 has a bead protrusion 601 extending into a gap between the first frame body 31 and the second frame body 32 of the tension frame 3, and the top of the bead protrusion 601 is adhered against the outer side surface of the second thermal insulation bridge 401. In this embodiment, when the second thermal insulation bridge-cut 401 is disposed, a gap for inserting the bead protrusion 601 of the adhesive bead 60 needs to be specially reserved around the first frame 31 and the second frame 32, so that the bead protrusion 601 can bear the pressing force of the glass to the second thermal insulation bridge-cut 401 when the glass is laid flat, and the second thermal insulation bridge-cut 401 is prevented from being crushed.

Further, in order to minimize heat transfer and moisture ingress into the bonding area while simultaneously compressing the bonding bead 60, in a preferred embodiment of the present application, the bottom of the first bead 102 and the second bead 502 extend below the bottom of the bonding bead 60 to form a sealing and compression relationship by compressing the beads, as shown in FIG. 1.
