Description

Technical Field

[0001] The present application relates to the field of energy-saving building technology, specifically to the manufacturing technology of hollow glass doors and windows in the field of energy-saving buildings, and especially to an assembly method of inner-hung film doors and windows. Background Art

[0002] In the field of energy-saving buildings, hollow glass doors and windows are usually used to isolate the temperature difference between indoors and outdoors and to achieve light transmission. Inner-hanging film doors and windows are lightweight energy-saving doors and windows developed on the basis of hollow glass doors and windows. The basic principle is to add one or more layers of transparent plastic film in the inner cavity of the hollow glass, and use the plastic film to isolate the inner cavity of the hollow glass into multiple independent spaces, so that the temperature difference between the inside and outside of the glass doors and windows cannot achieve convection, thereby reducing the weight of the structure while achieving excellent energy-saving effects.

[0003] US 2014 / 0023802 A1 discloses a multi-piece glazing unit with a flexibly mounted suspension film and a method for manufacturing the same, the glazing unit comprising a spacer, a plurality of first flexible mounting components extending from the spacer in a first direction, a plurality of second flexible mounting components attached to the first flexible mounting components, the first flexible mounting components being connected to the spacer at a first end, the second flexible mounting components extending from the spacer in a second direction, the second flexible mounting components being attached to an end of the spacer at a first point, a first flexible film being attached to a second end of the first flexible mounting components, a second flexible film being attached to a second end of the second flexible mounting components, and wherein the first film and the second film are substantially parallel to each other.

The flexible mounting component of the prior art can be a spring or other structural form. In order to maintain tension, a plurality of such springs need to be arranged on both sides of the spacer, and the tension state of the flexible film can be maintained by fully maintaining the tension of the flexible film. Although the above-mentioned prior art discusses that the installation of the flexible mounting component and the spacer can be operated by hand or machine, the connection between the flexible film and the flexible mounting component such as the spring obviously requires manual on-site installation, which is cumbersome and highly dependent on the experience of the installer.

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation of the present application is now described with reference to the accompanying drawings, wherein the same components are numbered the same.

[0031] In view of the difficulty of tensioning and the problem of inconsistent quality in the prior art, the present application proposes an inner hanging film door and window, such as Figure 1 As shown, the inner suspended film door and window of the present application includes two layers of hollow glass 1 arranged in parallel, and at least one layer of inner suspended film 2 is arranged inside the cavity between the two layers of glass 1. Of course, those skilled in the art should understand that, according to needs, two or more layers of inner suspended film 2 can also be arranged between the two layers of glass 1.

[0032] The inner suspension film 2 is made of a plastic film with good heat-resistance and insulation effects, and needs to be stretched between the insulating glass to keep the light transmitted in parallel and avoid visual distortion.

[0033] In order to facilitate installation, the inner suspended film 2 of the present application is arranged in a tensioned state inside a tensioning frame 3. The tensioning frame 3 can be installed between two layers of glass 1 as an independent component with the inner suspended film 2 in the tensioned state. Therefore, when installing the glass door and window, there is no need to consider the problem of on-site tensioning of the inner suspended film 2, which reduces the complexity of installation. Further, in the specific embodiment shown in the figure, the two sides of the tensioning frame 3 can be bonded between the two layers of glass 1 through the spacer 4. For example, the spacer 4 can adopt the existing composite butyl aluminum spacer, and the two sides of the spacer 4 are provided with butyl glue for bonding, and the hollow structure inside the spacer 4 is provided with a molecular sieve for absorbing water vapor. The inner suspended film door and window shown in the figure is only provided with a layer of inner suspended film 2. According to needs, it can also be deformed into a structure with two or more layers of inner suspended film 2 by adding a tensioning frame 3.

[0034] The tensioning operation of the inner suspension film in the prior art is very complicated. During installation, the four sides of the inner suspension film need to be clamped on many elastic elements respectively, and in order to prevent wrinkles, the tensioning force needs to be adjusted repeatedly locally. Figure 2 As can be seen from the exploded perspective view of the tensioning frame 3 shown, the four sides of the inner suspension film 2 of the present application are respectively wound on four reels 21 , and the two ends of the four reels 21 are respectively installed inside the tensioning frame 3 through elastic telescopic devices 5 .

[0035] In a specific embodiment shown in the figure, in order to facilitate the tensioning of the inner suspension film 2 while exposing the two ends of the reel 21, the inner suspension film 2 is a rectangle with four corners cut off, so that the width of the four sides of the inner suspension film 2 is narrower as it is closer to the edge position, so when it is wound on the reel 21, the closer to the middle of the reel 21, the thicker the winding thickness of the inner suspension film 2 on the reel 21, and the thinner the winding thickness of the inner suspension film near the two ends of the reel 21. In other words, the inner suspension film 2 wound on the reel 21 will generally form a spindle shape with a thick middle and thin ends. Therefore, as the inner suspension film 2 is tightly wound on the reel 21, the tensioning force at the middle position of the inner suspension film 2 will gradually become greater than the tensioning force at the corner position, which can offset the film extension and relaxation caused by the thermal expansion of the inner suspension film suspended in the middle. At the same time, the winding edge of the inner suspension film 2 will tend to extend to the two ends with thinner thickness, thereby naturally eliminating the phenomenon of wrinkles caused by local extrusion of the film.

[0036] In order to facilitate the winding of the inner suspension film 2 by the reel 21 to generate a balanced tension force, it is preferred that the cross section of the middle part of the reel 21 used to wind the inner suspension film 2 is circular. In addition, in order to facilitate the connection to the elastic expansion and contraction device 5 after tensioning without relaxation of the tension force, the cross section of the two ends of the reel 21 used to connect the elastic expansion and contraction device 5 is square, so that the reel 21 is not easy to rotate.

[0037] By winding the four sides of the inner suspension film on four reels respectively, the present application can obtain a greater tensioning force in the middle of the inner suspension film, offsetting the thermal relaxation of the inner suspension film, and naturally eliminating wrinkles through winding. Therefore, when installed on the tensioning frame, only the two ends of the tensioning reel need to be tightened, and there is no need to adjust the tensioning force of each point around the inner suspension film one by one, which greatly reduces the complexity of the tensioning operation.

[0038] Furthermore, if Figure 2 As shown, the tensioning frame 3 includes a first frame body 31 and a second frame body 32 clamped on both sides of the inner suspension film 2, and an elastic expansion device 5 is arranged inside a cavity formed by snapping the first frame body 31 and the second frame body 32. The tensioning frame 3 is snapped into a closed annular cavity by snapping the first frame body 31 and the second frame body 32. In the specific embodiment shown in the figure, each reel 21 is correspondingly provided with two elastic expansion devices 5, so a total of eight elastic expansion devices 5 are arranged inside the first frame body 31 and the second frame body 32. Due to the obstruction of the viewing angle, Figure 2 Only six elastic expansion and contraction devices 5 are shown. Every two elastic expansion and contraction devices 5 form a group, which are connected as a whole through an angle connecting piece 6 and are arranged together at the corner position of the tension frame 3.

[0039] The first frame 31 can be formed by splicing four profiles, for example Figure 3 As shown, the partial structure of two profiles at a corner position is shown. The four profiles can be connected as a whole by welding or bonding, or two adjacent profiles can be connected as a whole by screws through a corner connecting piece 6. At this time, the corner connecting piece 6 not only connects a group of two elastic expansion devices 5 at the corner position as a whole (connected as a whole by welding or screwing, etc.), but also connects two profiles as a whole. Figure 3 In the specific embodiment shown, the elastic expansion device 5 is arranged and installed on the first frame 31. Of course, those skilled in the art should understand that in an embodiment not shown, the elastic expansion device 5 can also be arranged and installed on the second frame 32.

[0040] The second frame 32 can be formed by integrally stamping a metal plate, or by integrally forming a metal casting or plastic injection molding, for example. Figure 4As shown. Alternatively, the second frame 32 can also be formed by splicing four profiles like the first frame 31. Alternatively, the first frame 31 can also be formed by metal or plastic as a whole like the second frame 32. Preferably, the frame for installing the elastic telescopic device 5 is spliced ​​by metal profiles so that it can have greater support strength to adapt to the tensioning operation; correspondingly, the other frame can be a metal or plastic one-piece molded part.

[0041] The second frame 32 may be Figure 1 As shown, the buckle is arranged on the inner side of the first frame 31, or in an embodiment not shown, the first frame 31 can also be buckled and arranged on the inner side of the second frame 32. In addition, in order to prevent the first frame 31 and the second frame 32 from being accidentally separated, the sides of the first frame 31 and the second frame 32 can also be reinforced by screws (screw holes are shown in the figure, but screws are not shown).

[0042] like Figure 3 , 4 As shown, the first frame 31 and the second frame 32 respectively have a first annular inner flange 311 and a second annular inner flange 321 in opposite positions, and the first annular inner flange 311 and the second annular inner flange 321 are respectively against two side surfaces of the inner suspension membrane 2 ( Figure 1 The first annular inner flange 311 and the second annular inner flange 321 abutting against the two side surfaces of the inner suspension film 2 clamp the inner suspension film 2, so that the cavities on both sides of the inner suspension film 2 cannot communicate with the interior of the first frame 31 and the second frame 32, so that the cavities on both sides of the inner suspension film 2 are well isolated, avoiding heat exchange of the airflow in the cavities on both sides.

[0043] Furthermore, in order to further improve the isolation effect, in an embodiment not shown, preferably, elastic sealing strips are installed at the tops of the first annular inner flange 311 and the second annular inner flange 321 that abut against the inner suspension membrane 2 .

[0044] Further, in Figure 1In the specific embodiment shown, the heights of the first annular inner flange 311 and the second annular inner flange 321 are just enough to make the inner suspension film 2 in a flat tensioned state, and the inner suspension film 2 is not lifted up by the first annular inner flange 311 or the second annular inner flange 321. In another embodiment not shown, the heights of the first annular inner flange 311 and the second annular inner flange 321 can be changed. For example, the height of the first annular inner flange 311 of the first frame 31 for installing the elastic telescopic device 5 can be slightly higher, so that the inner suspension film 2 is lifted up by the first annular inner flange 311 to form a bending angle after installation, thereby increasing the tension of the inner suspension film 2 and improving the sealing effect of the first annular inner flange 311 against the inner suspension film 2. Of course, in another embodiment not shown, the height of the second annular inner flange 321 can also be set to be slightly higher, so that the inner suspension film 2 is lifted up by the second annular inner flange 321 after installation.

[0045] It can be seen from the description of the structure of the inner suspended film door and window of the present application that in order to reduce the complexity of the tensioning operation of the inner suspended film 2, the inner suspended film 2 needs to be wound on the reel 21 first. Figure 5 As shown, usually, the inner suspension film 2 made of plastic film needs to be cut into a shape that is convenient for winding, that is, the four corners of the rectangular film are cut off, and the inner suspension films 2 cut into the shape are stacked layer by layer. Then, four reels 21 are placed above the edges of the four sides for winding operation, and the edges of the four sides of the inner suspension film 2 are fixedly connected to the four reels 21 respectively, for example, the four edges of the inner suspension film 2 are bonded to the four reels 21 by glue or double-sided tape, and finally the reels 21 are rotated to wind the inner suspension film 2 on the reels 21.

[0046] from Figure 5 It can be seen from the schematic diagram that although winding the inner suspension film 2 on the reel 21 does not seem complicated, in order to keep the inner suspension film 2 in a tensioned state during the winding process, four reels 21 need to be operated simultaneously and cannot be loosened. Any angular deviation will cause the four reels 21 to fail to maintain the correct position after winding, thereby causing the tension of the inner suspension film 2 to fail and cannot be used for installation between insulating glass.

[0047] In order to solve the problem that the tensioning operation of the inner suspended film 2 is complicated and easy to fail, the present application proposes a winding tensioning device that can be used for the inner suspended film door and window of the present application, which is used to tension the inner suspended film 2 by mechanical means, such as Figure 6-7 Through the mechanical structure of the winding tensioning device, the present application can achieve more precise alignment and coordinated winding operation compared to manual operation, avoid the problems of angle deviation and uneven winding tightness, and improve the overall tensioning quality and production efficiency.

[0048] like Figure 6-7As shown, the winding and tensioning device of the present application includes four reels 21 pressed on the four sides of the inner suspension film 2, and four belt clamping mechanisms 7 pressed above the four reels 21. The belt clamping mechanisms 7 rotate the reels 21 through friction force, and the four sides of the inner suspension film 2 are respectively wound on the four reels 21.

[0049] like Figure 8 As shown, the belt clamping mechanism 7 includes a clamping frame 71, in which two pulleys 72 are arranged, and a belt 73 is arranged around the two pulleys 72. The pulleys 72 are driven by a motor 74, driving the belt 73 to reciprocate around the pulleys 72, and the reel 21 is tightly pressed against the lower surface of the belt 73 of the belt clamping mechanism 7.

[0050] The belt 73 can be made of materials such as rubber, has considerable friction and certain elasticity, and can be used to press the lower surface of the belt 73 against the middle of the reel 21. When the belt 73 moves around the pulley 72, the reel 21 can be driven to rotate and the inner suspension film 2 can be wound around the reel 21 layer by layer.

[0051] In the present application, the operation of winding the inner suspension film 2 on the reel 21 is handled mechanically by four belt clamping mechanisms 7. As long as the positions of the stacked inner suspension film 2 and the belt clamping mechanisms 7 are kept accurate, the angle of the winding operation can be guaranteed not to deviate. In addition, since the belt 73 of the belt clamping mechanism 7 is elastic, the force of its downward pressing and rubbing can be kept uniform, and relative sliding will not occur. As long as the speed and time of the motor 74 are controlled, the number of winding layers can be controlled, and the winding accuracy can be well guaranteed without worrying about the influence of human factors.

[0052] Figure 6 The figure shows that the four sides of the inner suspension film 2 are wound on the four reels 21 by the belt pressing mechanism 7, and then the ends of the reels 21 can be fixed by snapping through the temporary corner connectors 60. The four reels 21 fixed at the four corners cannot be displaced relative to each other, thus forming a fixed tensioning state, thus completing the tensioning operation of a sheet of inner suspension film 2. After that, the belt pressing mechanism 7 can be raised, the tensioned inner suspension film 2 can be removed, and four reels 21 can be set above the stacked inner suspension film 2 again, and the belt pressing mechanism 7 can be pressed above the four reels 21, and the next tensioning operation process can be repeated.

[0053] like Figure 6-7As shown, further, in a specific embodiment, the belt pressing mechanism 7 can be fixedly mounted on an operating frame 8, and the operating frame 8 can be connected to a robot arm (not shown in the figure) or other driving mechanisms through structures such as a crossbeam 9, etc., for accurately controlling the pressing down, raising and positioning of the four belt pressing mechanisms 7. In the figure, corresponding to each belt pressing mechanism 7, a connecting column 81 is provided below the operating frame 8, and the belt pressing mechanism 7 is fixedly connected to the end of the connecting column 81.

[0054] Furthermore, if Fig. 9 As shown, the operating frame 8 is provided with positioning hooks 82 corresponding to the end positions of the four reels 21, and the ends of the reels 21 are against the top of the positioning hooks 82. As shown in the figure, each reel 21 is provided with two positioning hooks 82, and there are eight in total. Since the cross-section of the end of the reel 21 is square, the positioning hooks 82 are bent into right angles, so that the end of the reel 21 has two faces that can just fit with the right-angled sides of the positioning hooks 82. The outer width of the two positioning hooks 82 corresponding to each reel 21 can be exactly equal to the length of the reel 21, so when the reel 21 is placed above the two positioning hooks 82, the position of the reel 21 can be well determined. Of course, corresponding to the end shape of the reel 21, other types of positioning hooks 82 can also be provided.

[0055] When placing the reel 21 above the stacked inner suspension film 2, first align the two ends of the reel 21 and place them above the positioning hook 82, the middle part of the reel 21 slightly presses the belt 73 of the belt pressing mechanism 7 upward, so that the belt 73 is slightly bent and deformed upward, and the middle part of the reel 21 is pressed tightly on the lower surface of the belt 73 of the belt pressing mechanism 7, and the reel 21 is firmly stuck. When the belt pressing mechanism 7 presses down on the edge of the stacked inner suspension film 2, the inner suspension film 2 will press against the reel 21 to make the belt 73 further bend upward, and the operating frame 8 fixedly connected to the belt pressing mechanism 7 will move downward relative to the belt 73 as the belt 73 bends, so that the positioning hook 82 is separated from the end of the reel 21, and when the belt pressing mechanism 7 rubs the reel 21 to rotate, the positioning hook 82 will not hinder the rotation of the reel 21.

[0056] Furthermore, if Figure 10-12As shown, in a specific embodiment, the temporary corner connector 60 includes two slots 61 arranged at right angles, and the cross section of the slots 61 corresponds to the cross section of the end of the reel 21 (the size of the slots 61 is slightly larger than the end of the reel 21), so that the ends of two adjacent reels 21 arranged at right angles can be respectively clamped in one of the slots 61. In order to prevent the end of the reel 21 from slipping out of the slots 61, a locking inclined surface 62 is provided at the inner top of the slots 61. During installation, the end of the reel 21 is pressed downward into the slot 61 along the locking inclined surface 62 (the inner suspension film 2 is elastic and will be slightly stretched and then restored), and then the end of the reel 21 will be clamped below the locking inclined surface 62, and under the tension of the inner suspension film 2, the inner side wall of the slot 61 will press against the end of the reel 21. If the temporary corner connector 60 is to be removed, it is only necessary to pull the end of the reel 21 outward a little distance along the slot 61 so that the end is free from the constraint of the locking inclined surface 62, and the temporary corner connector 60 can be removed smoothly.

[0057] As mentioned above, after the inner suspension film 2 is tensioned on the four reels 21 by the winding and tensioning device, the ends of the four reels 21 are first fixed by snapping through the temporary corner connectors 60, so that the tensioned state of the inner suspension film 2 is fixed, and then the tensioned inner suspension film 2 can be transferred and installed inside the tensioning frame 3, that is, the temporary corner connectors 60 at the ends of the four reels 21 are removed one by one and instead clamped on the elastic telescopic device 5.

[0058] Please refer to the attached Figure 13-14 The specific structure of the elastic telescopic device 5 of the present application is further described in detail. As shown in the figure, the elastic telescopic device 5 includes a fixed base 51, a telescopic card seat 52 is arranged below the fixed base 51, and a spring 53 is arranged between the telescopic card seat 52 and the fixed base 51. In order to balance the force, two springs 53 are arranged side by side between the telescopic card seat 52 and the fixed base 51. The end of the reel 21 is hung on the telescopic card seat 52 and the inner suspension film 2 is tensioned by the spring 53.

[0059] Furthermore, the fixed base 51 can be formed by cutting and bending a metal plate as a whole, including a fixed top plate 511 that resists the first end of the spring 53, and the two sides of the fixed top plate 511 are respectively bent to form guide plates 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; a mounting screw hole 5131 is formed on the mounting plate 513, and the entire elastic telescopic device 5 can be installed inside the tensioning frame 3 by means of screws inserted into the mounting screw hole 5131.

[0060] Two positioning screw holes 5111 are provided on the fixed top plate 511 corresponding to the number of springs 53, and a positioning screw 5112 is provided in each positioning screw hole 5111. After the positioning screw 5112 passes through the positioning screw hole 5111, its end is penetrated at the end of the spring 53, so that the spring 53 will not be separated from the positioning screw 5112 and fail during the compression process.

[0061] The telescopic seat 52 can also be formed by cutting and bending a metal plate as a whole, including a movable top plate 521 that resists the second end of the spring 53, the bottom of the movable top plate 521 is bent toward one side of the fixed top plate 511 to form a telescopic guide plate 522, the end of the telescopic guide plate 522 passes through the guide opening 5113 at the bottom of the fixed top plate 511 and is bent upward to form a hanging plate 523, and the end of the hanging plate 523 is formed with a circular hook plate 524; the end of the square cross-section of the scroll 21 is non-rotatably stuck in the concave space formed by the telescopic guide plate 522, the hanging plate 523 and the circular hook plate 524.

[0062] A guide groove 5121 is formed on the guide plate 512 , and protrusions 5211 are respectively formed at both ends of the movable top plate 521 . The protrusions 5211 penetrate the guide groove 5121 and can move forward and backward along the guide groove 5121 .

[0063] When assembling the elastic telescopic device 5 of the present application, the telescopic card seat 52 is first deflected at a certain angle, the protrusion 5211 is inserted into the guide groove 5121, and then the telescopic card seat 52 is returned to the correct position, and the spring 53 is placed between the telescopic card seat 52 and the fixed base 51, and finally the positioning screw 5112 is screwed in to fix the position of the spring 53. After the fixed base 51 is installed on the tensioning frame 3, the telescopic card seat 52 is restricted below the fixed base 51 through the guide groove 5121 and the guide opening 5113. The telescopic card seat 52 can only move parallel to the guide groove 5121, and can provide a stable elastic force on the end of the reel 21.

[0064] The end of the reel 21 is a square cross-section structure, which can be clamped in the concave space of the telescopic guide plate 522, the hanging plate 523 and the circular hook plate 524 without rotation. The buckle structure is simple and effective, and the operation is very convenient. In addition, the elastic telescopic device 5 of the present application has a simple structure and high operating reliability. By converting the compression force of the spring 53 into a tensile elastic force, the elasticity of the entire structure is extremely high, and it can be used for life without maintenance.

[0065] Through the above detailed description of the structure of the inner suspended film doors and windows and the winding and tensioning device of the present application, those skilled in the art should be able to understand the general steps of the assembly method of the inner suspended film doors and windows of the present application. In order to avoid unclear steps, the steps scattered in the aforementioned detailed description are summarized below.

[0066] As mentioned above, the internal suspended film door and window of the present application comprises two layers of hollow glass 1 arranged in parallel, and at least one tensioning frame 3 for tensioning the internal suspended film 2 is arranged inside the cavity between the two layers of glass 1 .

[0067] Correspondingly, the assembly method of the inner suspended film door and window of the present application includes the following steps: first, cut the inner suspended film 2 into a rectangle with the four corners cut off; press four rollers 21 on the four sides of the cut inner suspended film 2; and fix the edges of the four sides of the inner suspended film 2 to the four rollers 21 respectively.

[0068] Among them, in order to facilitate winding, the edges of the four sides of the inner suspension film 2 can be fixedly connected to the four reels 21 respectively, for example, by applying glue to the edges of the four sides of the inner suspension film 2, or pre-bonding a double-sided tape on the reel 21, and tearing off the protective film on the double-sided tape when pressing the reel 21, and then pressing down the reel 21 to allow the four edges of the inner suspension film 2 to be bonded to the four reels 21.

[0069] Then, four belt pressing mechanisms 7 are pressed on the four reels 21 and the reels 21 are rotated by means of friction, so that the four sides of the inner suspension film 2 are respectively wound on the four reels 21 .

[0070] After the inner suspension film 2 is wound onto the reels 21 , the ends of the four reels 21 are buckled and fixed respectively through four temporary corner connectors 60 to keep the inner suspension film 2 in a tensioned state.

[0071] Afterwards, the inner suspension film 2 that is clamped and tensioned by the temporary corner connector 60 is transferred to the cavity of the tensioning frame, and the temporary corner connectors 60 are removed one by one, and the ends of the reels 21 that were originally fixed by the temporary corner connectors 60 are respectively hung on the elastic telescopic devices 5 that are fixedly connected to the tensioning frame 3. For example, one temporary corner connector 60 can be removed first, and the ends of the two reels 21 that were originally fixed by the temporary corner connector 60 are respectively hung on the two elastic telescopic devices 5; then the other three temporary corner connectors 60 are removed one by one, and the ends of the corresponding reels 21 are respectively hung on the other six elastic telescopic devices 5.

[0072] Finally, the tension frame 3 is buckled into a closed annular cavity, and the spacer strips 4 are respectively bonded to both sides of the tension frame 3, and a layer of glass 1 is respectively bonded to the outside of the spacer strips 4, thereby forming a Figure 1 The internal suspended membrane doors and windows shown.

[0073] Of course, in the case of having two or more layers of inner suspended films 2, as mentioned above, it is necessary to increase the number of tension frames 3. In this case, multiple tension frames 3 are buckled into a closed annular cavity, and then spacer bars 4 are bonded between adjacent tension frames 3 to form a whole, and finally a layer of glass 1 is bonded to the outside of the two outermost tension frames 3 through the spacer bars 4, thereby forming an inner suspended film door and window with multiple layers of inner suspended films 2.
