Description

Technical Field

[0001] The present invention relates to the field of architectural decoration, and in particular to a glass curtain wall. Background Art

[0002] Glass curtain wall (reflection glass curtain wall) refers to the building's external protective structure or decorative structure that has a certain displacement capacity relative to the main structure and does not share the effects on the main structure. Glass curtain wall can not only improve the appearance of the building, but also increase indoor lighting.

[0003] There are many types of glass curtain walls, among which the hidden frame glass curtain wall has no obvious metal components on both sides of the curtain wall, and has a better appearance. The traditional hidden frame glass curtain wall is to bond the glass panel to the aluminum alloy frame with silicone structural sealant (referred to as structural sealant), and then move the combination of the glass panel and the aluminum alloy frame to the vicinity of the curtain wall frame columns and beams, and then fix the aluminum alloy frame to the curtain wall frame with fasteners, and finally fill the gaps between the glass panels with sealing materials.

[0004] In order to save the construction cost of the metal frame, a hidden frame glass curtain wall using cables as the supporting structure has emerged. The curtain wall structure has cable anchor clamps pre-fixed on the cables. During construction, the two adjacent glass panels are fixed by the cable anchor clamps. Since the position of the cable anchor clamp cannot be adjusted during construction, the fixing position of the cable anchor clamp needs to be accurately designed according to the floor size. After the cable is pre-tightened at both ends, the actual position of the cable anchor clamp will deviate from the initial position, increasing the difficulty of design and construction. There may be deviations between the sizes and shapes of different glass panels. The tolerance of this structure is poor, and it is difficult to ensure stable docking between two adjacent glass panels. When one of the glass panels needs to be replaced separately, the original glass panel will be damaged, and the construction process is not safe enough. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] In one embodiment, if Figure 1 to Figure 5 As shown, the hidden cable connecting rod fixing the glass curtain wall includes a cable 1 and a cable 1 along the radial direction (reference Figure 1 The glass panels 2 are spliced ​​on both sides of the cable 1 (in the X direction), the cable 1 is fixed with a support 3, and one or more pairs of limit members 4 are installed on the support 3 along the length direction of the cable, and the two limit members 4 in the same pair are arranged on two opposite sides of the cable 1 in the radial direction, and one end of each limit member 4 is a connecting end hinged to the support 3, and the other end is a free end.

[0033] The glass panel 2 is provided with a limiting groove 21 at the edge facing the cable 1. When each limiting member 4 swings to the working position, the free end is inserted into the limiting groove 21 on the corresponding side, and when it swings to the initial position, it is separated from the limiting groove 21.

[0034] A locking member 5 is movably connected to the support 3 , and the locking member 5 has a release position for allowing the limiting member 4 to rotate, and a locking position for limiting the rotation angle of the limiting member 4 .

[0035] The glass panels 2 of this embodiment are prepared in advance before construction. During construction, the cables 1 are installed and pre-tightened outside the building, and then each glass panel 2 is installed on the cables 1 through structures such as the stopper 4. The support 3 can be fixed to the cables 1 in advance before construction, or fixed to the cables 1 during construction.

[0036] According to different on-site conditions, different ways of splicing glass curtain walls can be selected. When the size and position of the building and the glass panel 2 are exactly matched, the first installation method can be adopted, that is, the two limit members 4 belonging to the same pair are fixed to the same position by the locking member 5. Figure 2 The working position shown. At this time, one of the limit members 4 in the same pair extends into the limit groove 21 of the installed glass panel 2, and the other limit member 4 in the same pair is not covered by the glass panel and is in a suspended state. When the new glass panel is assembled with the existing glass panel, the limit member 4 in the suspended state extends into the limit groove 21 of the new glass panel 2. After the installation is completed, the two limit members 4 belonging to the same pair are respectively inserted into the limit grooves 21 on both sides of the cable 1, thereby limiting the relative movement of the two adjacent glass panels 2 along the thickness direction. This method has high installation efficiency and is conducive to shortening the construction period.

[0037] When the installation conditions at the construction site deviate, for example, when the size of the glass panel 2 deviates from the remaining installation space, this embodiment also provides a more flexible second installation method to ensure that the construction process continues. Figure 1 The locking release position is shown, and the stopper 4 is rotated to make it basically consistent with the extension direction of the cable 1. The gap between the new glass panel 2 and the existing glass panels is adjusted according to the remaining space position at the construction site until the gap between the new glass panel 2 and the remaining glass panels is basically consistent. The stopper 4 is then rotated to adapt to the gap between the new glass panels. The two stoppers 4 belonging to the same pair are respectively inserted into the stopper grooves 21 on both sides of the cable 1, and respectively abut against the glass panels 2 on both sides in the direction of the gap width, thereby adapting to the installation space with deviations and in the glass splicing direction (i.e. Figure 1 In the X direction in the figure, a rigid support is provided for each glass panel 2, thereby reducing the pressure of the structural adhesive and making the glass curtain wall structure more stable.

[0038] When one of the glass panels 2 needs to be replaced, for the traditional cable-type curtain wall structure, since the periphery of the glass panel 2 to be replaced is stuck by the stopper 4 pre-fixed to the cable 1, it is difficult to remove it without damaging the glass panel 2 to be replaced. For the glass curtain wall of this embodiment, the locking member 5 can be moved to the unlocking position first, and then the stopper 4 can be rotated to the initial position, so that the glass panel 2 to be replaced and the surrounding glass panels can move relative to each other, and then the entire glass panel 2 can be taken out along the thickness direction of the glass for replacement. The installation process during replacement is opposite to the removal process, so it will not be repeated. After the glass curtain wall is installed, glue can be applied to seal the glass joints.

[0039] The glass curtain wall of this embodiment has no obvious metal components when observed from both inside and outside after installation, has high aesthetics, and is easy to disassemble and assemble. By using the limiters 4 in pairs and arranging them on both radial sides of the cable 1, when the limiters 4 switch between the working position and the initial position, there will be no spatial interference between the limiters 4 and the cable 1, thereby ensuring the overall structural strength of the cable 1 and the limiters 4, and the glass curtain wall structure is stable.

[0040] In order to prevent the end of the stopper 4 from damaging the glass panel 2 when the stopper 4 is rotated during installation and removal, in one embodiment, Figure 3 , Figure 4 As shown, the edge of the glass panel 2 is covered with a reinforcing strip 22, and the cross section of the reinforcing strip 22 has a recessed area for forming a limiting groove 21. In one embodiment, the reinforcing strip 22 is made of a metal sheet, and the reinforcing strip 22 and the glass panel 2 are bonded and fixed.

[0041] In order to increase the friction resistance between the stopper 4 and the glass panel 2 and make the stopper 4 more firmly engaged, in one embodiment, as shown in FIG. Figure 3 , Figure 4 As shown, both ends of the stopper 4 are covered with a rubber layer 41. After the glass curtain wall is installed, in the thickness direction of the glass panel 2, the rubber layer 41 is clamped between the stopper 4 and the reinforcing strip 22, and plays a role of pre-tightening and vibration reduction.

[0042] In the process of the limiting member 4 swinging from the initial position to the working position, in order to ensure that the limiting member 4 can smoothly slide into the limiting groove 21, in one embodiment, as shown in FIG. Figure 3 As shown, the opening of the limiting groove 21 is provided with a transition arc surface 23 for guiding the limiting member 4 to enter. The local shape of the reinforcing strip 22 is adapted to the shape of the transition arc surface 23.

[0043] In one embodiment, the glass panel 1 adopts insulating glass, and the recessed area corresponds to the position of the middle gap of the insulating glass. The insulating glass includes two glass plates and a rigid support member connected between the two glass plates, and the edge of the insulating glass is coated with silicone structural adhesive. The glass plate includes a first tempered glass layer, an adhesive layer, and a second tempered glass layer stacked in sequence. In the thickness direction of the glass panel 1, the two sides of the reinforcing strip 22 are in contact with the edges of the glass plate, and the middle part of the reinforcing strip 22 is in contact with the silicone structural adhesive. The surface shape of the silicone structural adhesive is adapted to the shape of the limiting groove 11. The limiting member 4 adopts a width (width direction is Figure 3 In one embodiment, the width of the stopper 4 is 10 mm.

[0044] In order to adapt to the narrow space between the two glass panels 1, in one embodiment, as Figure 1 , Figure 2 As shown, the support 3 is a rigid cylinder fixedly sleeved on the cable 1. Specifically, in one embodiment, the rigid cylinder is an integrated structure, and the rigid cylinder of the integrated structure can be pre-fixed to the cable 1 before construction. In another embodiment, the rigid cylinder is a split structure that interlocks with each other in the radial direction, so that the fixed position of the rigid cylinder on the cable 1 can be flexibly adjusted at the construction site.

[0045] In one embodiment, the cable 1 is a segmented structure in the length direction, and two adjacent segments are respectively fixedly connected to two opposite sides of the support 3. For example, the cable 1 is a steel wire rope, which is fixed to the support 3 through a lifting ring. For another example, the cable 1 is a steel bar, which is fixed to the support 3 by welding, fasteners, etc.

[0046] In one embodiment, the rigid cylinder has lugs 31 on two opposite sides in the radial direction; two stoppers 4 belonging to the same pair are swingably mounted on the lugs 31 on the corresponding sides. Figure 2As shown, the rigid cylinder has lugs 31 on two opposite sides in the radial direction, and the lug 31 is provided with an extension portion 32 on one side in the length direction of the cable 1 , and the stopper 4 is swingably mounted on the extension portion 32 .

[0047] In order to lock the limiter 4 more firmly in the working position, in one embodiment, when the limiter 4 swings to the working position, the limiter 4 is respectively restrained against the lug 31 and the locking member 5 on both sides of the length direction of the cable 1. In the swinging plane of the limiter 4, the connecting end of the limiter 4 is arc-shaped, and the hinged position of the limiter 4 and the extension 32 is close to the lug 31. When the limiter 4 is in the initial position, the connecting end of the limiter 4 contacts the surface of the lug 31. The lug 31 and the locking member 5 are respectively provided with a first plane portion on the side facing the limiter 4. When the limiter 4 is in the working position, the limiter 4 is provided with a second plane portion on both sides along the length direction of the cable. When the limiter 4 is in the working position, the two second plane portions of the limiter 4 are respectively in contact with the two first plane portions on the corresponding sides, and the limiter 4 and the lug 31 and the locking member 5 are in surface contact, which is not easy to shake, thereby stably keeping the limiter 4 in the working position.

[0048] In one embodiment, if Figure 2 As shown, the locking member 5 is an annular disk slidably mounted on the rigid tube; when the locking member 5 is in the locking position, the radial sides of the locking member 5 respectively abut against the two limiting members 4 of the same pair in the length direction of the cable 1.

[0049] In one embodiment, the radial direction of the annular disk is perpendicular to the length direction of the cable 1. The two lugs 31 arranged opposite to each other in the radial direction form a pair. The two stoppers 4 belonging to the same pair are at the same position in the length direction of the cable 1. When the two stoppers 4 belonging to the same pair are in the initial position, the two ends of the stoppers 4 are close to or in contact with the lugs 31 and the locking member 5, respectively. When the stoppers 4 are in the locking position, the locking member 5 and the pair of lugs 31 clamp the pair of stoppers 4 to fix them in the working position.

[0050] In order to disperse the stress on the glass panel 2, in one embodiment, as shown in FIG. Figure 2 As shown, in the length direction of the cable 1, a pair of lugs 31 are respectively provided at both ends of the rigid tube, and the two locking members 5 are located between the two pairs of lugs 31; the two locking members 5 are respectively abutted against a pair of lugs 31 on the corresponding side to limit the position.

[0051] In order to facilitate the removal and replacement of a glass panel 2 of the glass curtain wall, in one embodiment, Figure 2 As shown, when the limiting member 4 swings to the working position, the connection end of the limiting member 4 is located outside the glass panel 2. With this arrangement, the limiting member 4 can be swung without inserting a tool into the limiting groove 21 during disassembly, which is convenient for operation.

[0052] In one embodiment, if Figure 1 , Figure 2 As shown, the outer circumference of the rigid cylinder is provided with at least two limiting structures arranged in the axial direction, which are used to keep the locking member 5 in the unlocking position and the locking position respectively. The limiting structure is a limiting protrusion 33 provided on the support 3, and the locking member 5 is provided with a limiting recess 51 that matches the limiting protrusion 33. In another embodiment, the limiting structure is a limiting recess provided on the support 3, and the locking member is provided with a limiting protrusion that matches the limiting recess. When the limiting protrusion and the limiting recess cooperate, an appropriate locking force is generated, which can prevent the limiting member 4 from rotating and allow disassembly and separation.

[0053] In order to facilitate the unlocking of the locking member 5 during replacement, in one embodiment, the locking member 5 is provided with a disassembly force applying structure, which is located on the side of the locking member 5 facing away from the limiting member 4. In one embodiment, the disassembly force applying structure is formed by a slot in the locking member 5. In another embodiment, the disassembly force applying structure is detachably mounted on the locking member 5. For example, the disassembly force applying structure is a lifting ring connected to the locking member 5.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
