Description

Technical Field

[0001] This utility model relates to the field of hidden frame glass curtain wall technology, and in particular to a hidden frame glass curtain wall. Background Technology

[0002] A frameless glass curtain wall is a modern architectural curtain wall form that completely or partially conceals a metal frame behind glass. The glass is directly bonded to the aluminum or steel frame using structural adhesive, creating a continuous and transparent facade. Because frameless glass curtain walls eliminate the metal dividing lines of traditional curtain walls, achieving a "large glass surface" effect, they can create an architectural texture that blends solid and void. Therefore, they are widely used in public buildings such as airports, museums, opera houses, exhibition halls, and hospitals, not only satisfying people's aesthetic requirements for architecture but also improving the building's lighting needs.

[0003] To ensure the flatness of the surface of the frameless glass curtain wall, it is necessary to ensure that the thickness of the frameless glass used is consistent. However, during the construction process, there is often a shortage of frameless glass of the same thickness, which requires the use of frameless glass of different thicknesses in the same frameless glass curtain wall, thus increasing the construction difficulty of the frameless glass curtain wall. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a frameless glass curtain wall that reduces construction difficulty while ensuring the flatness of the frameless glass curtain wall.

A pressure plate is used to press two horizontally adjacent hidden frame glass panels onto the middle column so that the hidden frame glass curtain wall remains flat in the horizontal direction. The upper and lower ends of the thick hidden frame glass are respectively fixed to the corresponding horizontal beams by the first glass sub-frame, and the upper and lower ends of the thin hidden frame glass are respectively fixed to the corresponding horizontal beams by the second glass sub-frame, wherein the second glass sub-frame is provided with a thickness adjustment block to keep the hidden frame glass curtain wall flat in the longitudinal direction.

[0006] Furthermore, a first connecting screw is provided on the column, and a first connecting nut is provided on the first connecting screw. The first connecting screw and the first connecting nut cooperate to connect the pressure plate to the column.

[0007] Furthermore, the pressure plate is also connected to a detachable decorative cover, which is used to decorate and protect the pressure plate.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] This embodiment provides a frameless glass curtain wall, which includes a keel structure and multiple frameless glass panels assembled on the keel structure. The thickness of each frameless glass panel can be the same or different, so as to reduce the construction difficulty of the frameless glass curtain wall.

[0023] In this embodiment, the frameless glass curtain wall's keel structure includes multiple columns 1 whose length direction is vertical or forms a predetermined angle with the vertical direction. These columns 1 can be made of aluminum alloy and are distributed sequentially. Between every two adjacent columns 1, multiple horizontal beams 2 at different heights are provided. These horizontal beams 2 are also made of aluminum alloy, thus forming a grid-like keel structure. Each grid is fitted with a frameless glass 3, which is not only adhered to its corresponding grid but also connected at its left and right ends to the left and right columns 1 of its corresponding grid, and at its top and bottom ends to the top and bottom horizontal beams of its corresponding grid.

[0024] Since the thickness of the hidden frame glass 3 in the hidden frame glass curtain wall is different, in order to facilitate the description of the technical solution of this utility model, in this embodiment, the hidden frame glass 3 with the largest thickness is first identified, the thickness of the hidden frame glass 3 is used as a set thickness threshold, and the hidden frame glass 3 with the thickness of the set thickness threshold is used as thick hidden frame glass, and the hidden frame glass 3 with the thickness less than the set thickness threshold is used as thin hidden frame glass.

[0025] In this embodiment, if two adjacent hidden frame glass panels 3 in the hidden frame glass screen are both thick hidden frame glass, the connection method between these two hidden frame glass panels 3 and the crossbeam 2 in the middle is as follows: Figure 1 As shown, in the two adjacent frameless glass panes 3, the bottom end of the upper frameless glass pane 3 is attached to a first glass sub-frame 411 by a first structural adhesive 421, and the top end of the lower frameless glass pane 3 is attached to another first glass sub-frame 411 by a second structural adhesive 422. Both first glass sub-frames 411 are fixed to the crossbeam 2 between the two frameless glass panes 3, thereby fixing the two frameless glass panes 3 to the keel structure.

[0026] If one of the two adjacent frameless glass panes 3 in a frameless glass screen is a thick frameless glass pane and the other is a thin frameless glass pane, then the connection method between these two frameless glass panes 3 and the crossbeam 2 in the middle is as follows: Figure 2In the two adjacent frameless glass panes 3 shown, assuming the upper frameless glass pane 3 is thin and the lower frameless glass pane 3 is thick, the top of the lower frameless glass pane 3 is adhered to a first glass sub-frame 411 using a second structural adhesive 422, and the bottom of the upper frameless glass pane 3 is adhered to a second glass sub-frame 412 using a first structural adhesive 421. The second glass sub-frame 412 is equipped with a thickness adjustment module 413, and the sum of the thickness of the thickness adjustment module 413 and the thickness of the upper frameless glass pane 3 is equal to the thickness of the lower frameless glass pane 3. Both first glass sub-frames 411 are fixed to the crossbeam 2 between the two frameless glass panes 3, thus not only fixing the two frameless glass panes 3 of different thicknesses to the keel structure, but also ensuring the longitudinal flatness of the frameless glass curtain wall.

[0027] If the two adjacent hidden frame glass panes 3 in the hidden frame glass screen are both thin hidden frame glass panes, then the connection method between these two hidden frame glass panes 3 and the crossbeam 2 in the middle is as follows: Figure 3 As shown, in the two adjacent frameless glass panels 3, the bottom end of the upper frameless glass panel 3 is attached to a second glass sub-frame 412 using a first structural adhesive 421, and the bottom end of the lower frameless glass panel 3 is attached to another second glass sub-frame 412 using a second structural adhesive 422. Both second glass sub-frames 412 are equipped with corresponding thickness adjustment modules 413, and the sum of the thickness of each frameless glass panel 3 and the thickness of the thickness adjustment module 413 on the connected second glass sub-frame 412 equals a set thickness threshold. Both first glass sub-frames 411 are fixed to the crossbeam 2 between the two frameless glass panels 3, thus not only fixing the two frameless glass panels 3 to the keel structure in the middle but also ensuring the longitudinal flatness of the frameless glass curtain wall.

[0028] In this embodiment, if two adjacent frameless glass panels 3 in the frameless glass screen are both thick frameless glass panels, the connection method between these two frameless glass panels 3 and the central pillar 1 is as follows: Figure 4As shown, the left and right ends of the exterior of the column 1 are respectively provided with a first glass groove 101, a second glass groove 102, and a connecting structure 110, and a first connecting screw 103 is provided on the connecting structure 110. The right end of the inner side of the left-side concealed frame glass 3 is connected to the first glass groove 101 via a first adhesive strip 121, and the left end of the inner side of the right-side concealed frame glass 3 is connected to the second glass groove 102 via a second adhesive strip 122. The left and right sides of the pressure plate 13 are respectively provided with a third glass groove 131 and a fourth glass groove 132. The right end of the outer side of the left-side concealed frame glass 3 is connected to the third glass groove 131 via a third adhesive strip 141, and the left end of the outer side of the right-side concealed frame glass 3 is connected to the fourth glass groove 132 via a fourth adhesive strip 142. A through hole is provided on the pressure plate 13. The first connecting screw 104 passes through the through hole and is threadedly connected to the first connecting nut 104. Thus, the pressure plate 13 is connected to the column 1 under the cooperation of the first connecting screw 104 and the first connecting nut 104, so as to press the two hidden frame glass 3 onto the column 1, thereby improving the stability of the two hidden frame glass 3 assembled on the keel structure.

[0029] If one of the two adjacent frameless glass panes 3 in a frameless glass screen is a thick frameless glass pane and the other is a thin frameless glass pane, then the connection method between these two frameless glass panes 3 and the central pillar 1 is as follows: Figure 5 As shown, the left-hand hidden frame glass 3 is a thick hidden frame glass, and the right-hand hidden frame glass 3 is a thin hidden frame glass. A thickness compensation component 12 is installed in the second glass slot 102 located to the right of the column 1. This thickness compensation component 12 can be made of aluminum alloy and is snap-fitted into the second glass slot 102. A second adhesive strip 122 is provided on the thickness compensation component 12, and the sum of the thickness of the thickness compensation component 12 and the thickness of the thin hidden frame glass is equal to a set thickness threshold. Under the action of the pressure plate 13, the two hidden frame glass 3s are pressed onto the column 1, which can improve the stability of the two hidden frame glass 3s assembled on the keel structure. Furthermore, the thickness compensation component 12 can keep the two hidden frame glass 3s flat, thereby ensuring the horizontal flatness of the hidden frame glass curtain wall.

[0030] If the two adjacent frameless glass panels 3 in the frameless glass screen are both thin frameless glass panels, then the connection method between these two frameless glass panels 3 and the central pillar 1 is as follows: Figure 6 As shown, thickness compensation components 12 are respectively installed in the first glass slot 101 on the left side of the column 1 and the second glass slot 102 on the right side. These two thickness compensation components 12 can be made of aluminum alloy and are respectively snapped into the first glass slot 101 and the second glass slot 102. The sum of the thickness of each thickness compensation component 12 and the thickness of its corresponding thin frameless glass is equal to the set thickness threshold, thereby ensuring the flatness of the frameless glass curtain wall in the horizontal direction.

[0031] As described above, in this embodiment, the left and right ends of the thin, frameless glass with a thickness less than a set thickness threshold are connected to corresponding glass slots via thickness compensation components, and the upper and lower ends are fixed to corresponding horizontal beams via second glass sub-frames. The second glass sub-frames are equipped with thickness adjustment blocks, thereby ensuring the frameless glass curtain wall remains flat horizontally under the action of the thickness compensation components and vertically under the action of the thickness adjustment blocks. Therefore, this embodiment allows the frameless glass curtain wall to remain flat when using frameless glass of different thicknesses, thus reducing the construction difficulty of the frameless glass curtain wall.

[0032] In the above embodiment, the pressure plate 13 is connected to the column 1 through the cooperation of the first connecting screw 103 and the first connecting nut 104. Since the through hole on the first connecting screw 104 can be opened first during the process of connecting the pressure plate 13 to the column 1, the pressure plate 13 can be positioned by the first connecting screw 104, which improves the convenience of assembling the hidden frame glass 3.

[0033] In other embodiments of this utility model, the pressure plate 13 can be connected to the column 1 in other ways. For example, a screw hole can be provided on the connecting structure 110. During the process of connecting the pressure plate 13 to the column 1, a bolt can be inserted from the outside into the through hole on the pressure plate 13 and threadedly connected to the screw hole on the connecting structure 110, thereby connecting the pressure plate 13 to the column 1.

[0034] In some embodiments of this utility model, the pressure plate 13 is also connected to a detachable decorative cover 14. For example, the decorative cover 14 can be made of aluminum alloy, and the decorative cover 14 can be detachably connected to the pressure plate 13 by threads or snap-fitted to the pressure plate 13.

[0035] After the pressure plate 13 is connected to the column 1, a decorative cover 14 can be fitted onto the pressure plate 13 to decorate and protect it, preventing the first connecting screw 103 and the first connecting nut 104 from sticking together due to corrosion. If it is necessary to remove the frameless glass 3, the decorative cover 14 can be removed from the pressure plate 13, and then the first connecting nut 104 can be removed from the first connecting screw 103 to disengage the clamping connection between the two frameless glass panes 3 and the column 1.

[0036] Since the decorative cover 14 in this embodiment can improve the protection of the pressure plate 13, the first connecting screw 103, and the first connecting nut 104, the safety of the hidden frame glass curtain wall can be improved.

[0037] In some embodiments of this utility model, in every two adjacent hidden frame glass panes, the glass sub-frame connected to the lower end of the upper hidden frame glass 3 and the glass sub-frame connected to the upper end of the lower hidden frame glass 3 are connected to the crossbeam 2 by corresponding pressure blocks 40.

[0038] In this embodiment, the glass sub-frames connected to the concealed frame glass 3 are either a first glass sub-frame 411 or a second glass sub-frame 412, and each glass sub-frame is provided with a U-shaped frame. The pressure block 40 is provided with a through hole and is located in the area formed by the two U-shaped frames. A second connecting screw 401 is provided on the crossbeam 2. The second connecting screw 401 passes through the through hole on the pressure block 40 and is threadedly connected to a second connecting nut 402 to fix it to the crossbeam 2. The glass sub-frame frames of adjacent concealed frame glass 3 are assembled between the pressure block 40 and the crossbeam 2, thereby fixing the glass sub-frames of adjacent concealed frame glass 3 to the crossbeam 2 under the action of the pressure block 40. To improve the reliability of the glass sub-frame pressing on the crossbeam 2, in this embodiment, a first rubber pad 51 is provided between the glass sub-frame connected to the lower end of the upper concealed frame glass 3 and the crossbeam 2, and a second rubber pad 52 is provided between the glass sub-frame connected to the upper end of the lower concealed frame glass 3 and the crossbeam 2.

[0039] In this embodiment, the pressure block 40 is used to fix the glass sub-frames of the adjacent hidden frame glass 3 to the crossbeam 2, which will not damage the glass sub-frames of the hidden frame glass; and a second connecting screw 401 is provided on the crossbeam 2. During the assembly of the pressure block 40, the second connecting screw 401 can play a positioning role for the pressure block 40, thereby improving the convenience of assembling the pressure block 40.

[0040] In the above embodiment, the glass sub-frames of two adjacent hidden frame glass 3 are pressed onto the crossbeam 2 by pressure block 40; in other embodiments, other connection methods can be used to connect the glass sub-frames of two adjacent hidden frame glass 3 to the crossbeam 2. For example, corresponding screw holes can be provided on the glass sub-frames of the two hidden frame glass 3 respectively, and two bolts can be passed through one screw hole and threadedly connected to the crossbeam 2 to connect the glass sub-frames of the two hidden frame glass 3 to the crossbeam 2 respectively.

[0041] In other embodiments, the pressure block 40 can be connected to the crossbeam 2 in other ways. For example, a screw hole can be provided on the crossbeam 2, and then a bolt can be passed through the through hole on the pressure block 40 and threaded into the screw hole to connect the pressure block 40 to the crossbeam 2.

[0042] In some embodiments of this utility model, each crossbeam 2 is provided with a sub-frame cover 410, which is used to protect the glass sub-frame connected to the crossbeam 2.

[0043] In this embodiment, the sub-frame cover 410 is made of aluminum alloy and can be fixed to the crossbeam 2 by pasting or detachably assembled to the crossbeam 2 by snap-fitting. That is, a slot is provided on the crossbeam 2 and a clip is provided on the sub-frame cover 410. Through the cooperation between the slot and the clip, the sub-frame cover 410 is detachably assembled to the crossbeam 2.

[0044] In this embodiment, the glass sub-frame connected to the crossbeam 2 can be either a first glass sub-frame 411 or a second glass sub-frame 412, or both. Since the second glass sub-frame 412 contains a thickness adjustment module 413, its width is greater than that of the first glass sub-frame 411. Accordingly, to improve the protective effect on the glass sub-frames, the width of each sub-frame cover 410 in this embodiment matches the width of its corresponding glass sub-frame.

[0045] In this embodiment, a sub-frame cover 410 is provided on each crossbeam 2 to protect the glass sub-frame. This can prevent the glass sub-frame from being damaged and thus prevent the hidden frame glass 3 from being unable to be connected to the crossbeam 2. Therefore, it can improve the reliability of the hidden frame glass 3 in the frameless glass curtain wall assembly on the keel structure.

[0046] In some embodiments of this utility model, each frameless glass 3 is provided with a corresponding glass support 61 at its bottom, and each glass support 61 is connected to the crossbeam 2 below its corresponding frameless glass 3 to provide support for the frameless glass 3.

[0047] In this embodiment, the glass support 61 can be made of aluminum alloy and connected to the crossbeam 2 below the corresponding frameless glass 3, for example, by welding it to the crossbeam 2 or by bolting it detachably to the crossbeam 2, in order to support the downward gravity of the frameless glass 3 and prevent it from falling off the keel structure.

[0048] Therefore, in this embodiment, a corresponding glass support 61 is provided at the bottom of each frameless glass 3, which can improve the stability of the frameless glass 3 on the keel structure and thus further improve the safety of the frameless glass curtain wall.

[0049] In some embodiments of this utility model, a foam 62 is provided between adjacent frameless glass 3, and a sealant is used for sealing.

[0050] In this embodiment, the filling foam 62 can be foam rods. Not only is filling foam 62 provided between every two adjacent hidden frame glass 3s on the top and bottom, but filling foam 62 is also provided between every two adjacent hidden frame glass 3s on the left and right. Furthermore, the adjacent hidden frame glass 3s are sealed with sealant after the filling foam 62 is provided to prevent the filling foam from absorbing moisture and dust.

[0051] In this embodiment, foam is filled and sealed between adjacent frameless glass 3 to prevent moisture or dust from accumulating in the gaps of the frameless glass 3 and corroding the frameless glass 3, thereby improving the service life of the frameless glass curtain wall.

[0052] In some embodiments of this utility model, each crossbeam 2 has a core 20 at both ends, and each core 20 is made of aluminum alloy. Each core 20 is connected to the column 1 via a corresponding pin 201. Each crossbeam 2 is inserted into its corresponding core 20 at both ends, and each crossbeam 2 is connected to its corresponding core 20 via a third screw 202. Thus, each crossbeam 2 is connected to the columns 1 on both sides of it via its corresponding core 20.

[0053] In this embodiment, each crossbeam 2 is connected to the columns 1 on both sides by insert 20, which not only improves the reliability of insert 20 assembly on crossbeam 2, but also improves the convenience of assembly process.

[0054] In some embodiments of this utility model, a corresponding third rubber pad 21 is provided between each crossbeam 2 and the column 1 it is connected to.

[0055] In this embodiment, the thickness of each crossbeam 2 matches the thickness of the frameless glass 3 it is connected to. The greater the thickness of the frameless glass 3, the smaller the thickness of its corresponding crossbeam 2; conversely, the smaller the thickness of the frameless glass 3, the greater the thickness of its corresponding crossbeam 2. Therefore, in order to ensure the reliability of the connection between each crossbeam 2 and its two side columns 1, the size of each third rubber pad 21 corresponds to the thickness of its corresponding crossbeam 2.

[0056] In this embodiment, a third rubber pad 21 is provided between the crossbeam 2 and the column 1 it is connected to. This not only seals the gap between the crossbeam 2 and the column 1 under the action of the third rubber pad 21, but also improves the reliability of the connection between the crossbeam 2 and the column 1, thereby improving the stability of the hidden frame glass curtain wall.

[0057] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
