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

[0030] 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.

[0031] 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.

[0032] 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.

[0033] In one embodiment, if Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the hidden cable spring-loaded fixed glass curtain wall includes a cable 1 and glass panels 2 radially spliced ​​on both sides of the cable 1. The glass curtain wall also includes a support 3, a limiting groove 21, two limiting sliders 4 and two limiting frames.

[0034] The support 3 is fixed to the cable 1. The limiting groove 21 is opened on the side of the glass panel 2 facing the cable 1. Two limiting sliders 4 are slidably connected to the support 3 along the length direction of the cable 1, and the two limiting sliders 4 have locking positions close to each other (such as Figure 2 as shown) and unlocked positions that are far from each other (as shown Figure 1 shown).

[0035] The two limit frames are respectively located on both sides of the cable 1 in the radial direction, and each limit frame includes two connecting rods 5. The two connecting rods 5 in the same limit frame are respectively hinged to the two limit sliders 4, and one end of the connecting rod 5 hinged to the limit slider 4 is the sliding end, and the free ends of the two connecting rods 5 are hinged to each other. When the two limit sliders 4 are in the locked position, the free ends of the two connecting rods 5 are inserted into the limit grooves 21 on the corresponding side, and the limit frame is in the unfolded state. When the two limit sliders 4 are in the unlocked position, the free ends of the two connecting rods 5 are separated from the limit grooves 21 on the corresponding side, and the limit frame is in the folded state.

[0036] The glass panel 2 of this embodiment is prepared in advance before construction. During construction, the cable 1 is installed and pre-tightened outside the building, and then the glass panel 2 is assembled on one side of the cable 1. After assembly, the two limit frames connected to the cable 1 are respectively inserted into the limit grooves 21 of the glass panel 2 on the corresponding side. The support 3 can be fixed to the cable 1 in advance before construction, or it can be fixed to the cable 1 during construction.

[0037] 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 just match, the first installation method can be adopted, that is, the two limit frames are fixed to the same position by the limit slider 4. Figure 2The expanded position shown. At this time, one of the two limit frames extends into the limit groove 21 of the installed glass panel 2, and the other limit frame 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 frame in the suspended state extends into the limit groove 21 of the new glass panel 2. After the installation is completed, the two limit frames 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 in the thickness direction. This method has high installation efficiency and is conducive to shortening the construction period.

[0038] 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 unlocking position shown is then adjusted according to the remaining space position at the construction site until the gaps between the new glass panel 2 and the remaining glass panels are substantially consistent. The two limit sliders 4 are then moved closer to each other, and the two limit sliders 4 clamp the limit frame from both ends to deform the limit frame. During deformation, the free ends of the two connecting rods 5 gradually move away from the cable 1 until they are aligned with the bottom end of the limit groove 21, thereby adapting the shape and size of the limit frame to the gaps between the new glasses. This embodiment uses a deformable limit frame to not only adapt to installation spaces with deviations, but also to provide a smooth and stable installation in the glass splicing direction (i.e., Figure 2 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.

[0039] 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 rigid limiter pre-fixed on 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 limit slider 4 can be moved to the unlocking position along the gap between the glass panels 2. While the distance between the two limit sliders 4 increases, the free end of the connecting rod 5 is driven to gradually approach the cable 1. Finally, the free end of the connecting rod 5 is disengaged from the limit groove 21, and the limit frame and the glass panel 2 no longer interfere with each other in the thickness direction of the glass panel 2. Then, the entire glass panel 2 is taken out along the thickness direction of the glass panel 2 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.

[0040] 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 limit frames in pairs and arranging them on both radial sides of the cable 1, when the limit frames switch between the working position and the initial position, there will be no spatial interference between the limit frames and the cable 1, thereby ensuring the overall structural strength of the cable 1 and the limit frames, and the glass curtain wall structure is stable.

[0041] In order to prevent the free end of the connecting rod 5 from damaging the glass panel 2 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.

[0042] In order to increase the friction resistance between the limit frame and the glass panel 2 and make the limit frame more firmly connected, in one embodiment, as shown in FIG. Figure 3 , Figure 4 As shown, the free end of the connecting rod 5 is coated with a rubber layer 51. After the glass curtain wall is installed, in the thickness direction of the glass panel 2, the rubber layer 51 is clamped between the connecting rod 5 and the reinforcing strip 22, and plays a role of pre-tightening and vibration reduction.

[0043] In the process of the limiting slide block 4 sliding from the unlocking position to the locking position, in order to ensure that the limiting frame can slide smoothly 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 frame to enter the limiting groove 21. The local shape of the reinforcing strip 22 is adapted to the shape of the transition arc surface 23.

[0044] In one embodiment, the glass panel 2 is made of 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 2, 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 connecting rod 5 adopts a width (width direction is Figure 3 In one embodiment, the width of the connecting rod 5 is 10 mm.

[0045] In order to adapt to the narrow space between the two glass panels 2, in one embodiment, Figure 1 , Figure 2As 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.

[0046] 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.

[0047] In order to minimize the radial dimension of the limit frame along the cable 1 in the folded state so as to facilitate the separate removal of one of the glass panels 2, in one embodiment, as shown in FIG. Figure 2 As shown, the limiting slider 4 includes an annular disk 41 slidably mounted on the rigid cylinder, and a mounting portion 42 extending from the edge of the annular disk 41 along the length direction of the cable; the connecting rod 5 is hinged to the mounting portion 42 on the corresponding side.

[0048] In order to maximize the adjustable range of the limit frame, in one embodiment, Figure 2 As shown, the two connecting rods 5 have the same length. When the limiting slider 4 slides along the support 3, even when the sliding ends of the two connecting rods 5 are close to each other, it can be ensured that the two connecting rods 5 and the support 3 can always form a triangular support structure. Thus, when the gap between the glass panels 2 is large, the limiting frame can also abut against the bottom of the limiting groove 21.

[0049] In order to disperse the stress on the glass panel 2, in one embodiment, when the two limit sliders are in the locked position, the angle between the two connecting rods (i.e. Figure 2 The angle a) in the figure is 45° to 90°. Within this angle range, the triangle formed by the two connecting rods 5 and the support 3 has a larger area, thereby preventing the stress generated by the limit frame from being concentrated near a certain straight line, and the glass panel 2 is not easy to break.

[0050] In order to further reduce the radial dimension of the limit frame along the cable 1 in the folded state, in one embodiment, Figure 1 As shown, when the two limit sliders 4 are in the unlocking position, the two connecting rods 5 extend along the length direction of the cable 1 and are close to the support 3.

[0051] In one embodiment, if Figure 1 , Figure 2As shown, the outer circumference of the rigid cylinder is provided with at least two limiting structures arranged along the length direction of the cable, which are used to keep the limiting slider 4 in the unlocking position and the locking position respectively. The limiting structure is a limiting protrusion 31 provided on the support 3, and the limiting slider 4 is provided with a limiting recess 43 that matches the limiting protrusion 31. In another embodiment, the limiting structure is a limiting recess provided on the support 3, and the limiting slider 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 frame from rotating and allow disassembly and separation.

[0052] In order to facilitate the release of the locking state of the limit slider 4 during replacement, in one embodiment, the limit slider 4 is provided with a disassembly force-applying structure, and the disassembly force-applying structure is located on the side of the limit slider 4 facing away from the limit frame. In one embodiment, the disassembly force-applying structure is formed by a groove of the limit slider 4. In another embodiment, the disassembly force-applying structure is detachably mounted on the limit slider 4. For example, the disassembly force-applying structure is a lifting ring connected to the limit slider 4.

[0053] 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.

[0054] 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.
