DETAILED DESCRIPTION OF THE INVENTION

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0040] Combined with Figures 1 to 8 Describing this embodiment, this embodiment provides an installation structure for a stone curtain wall, which includes a keel frame 1, a mounting frame 2, a plug-in member 3, and a stone panel 4. The keel frame 1 is fixedly connected to the building exterior wall through embedded parts. The outer side surface of the keel frame 1 has a cross plane distributed in a matrix. The mounting frame 2 is fixed on the cross plane. The mounting frame 2 includes a bottom plate 21 and several angle members 22. The angle members 22 are symmetrically welded to the bottom plate 21 in pairs. The angle members 22 have elastic cantilevers 23. The free end of the elastic cantilever 23 is bent to form a plug-in head 24. The plug-in member 3 is used to be plugged between two angle members 22, and the plug-in member 3 abuts against the connecting part 25 of the elastic cantilever 23 and the plug-in head 24. A plug-in groove 41 is provided on the side surface of the corner of the stone panel 4. The plug-in groove 41 matches the plug-in head 24. The stone panel 4 is placed inside the angle members 22 distributed in a matrix. The inner surface of the stone panel 4 abuts against the bottom plate 21. When specifically installing, a rubber pad can also be attached to the upper surface of the bottom plate 21 to improve the seismic performance of the stone panel 4. After the stone panel 4 is installed in place, the plug-in head 24 is plugged into the plug-in groove 41.

[0041] As Figures 4 - 5 shown, the keel frame 1 includes vertical keels 11 and horizontal keels 12. The vertical keels 11 are square tube structures. The horizontal keels 12 are square tube structures or angle steel bars. In this example, the horizontal keels 12 are right-angle steel bars. The vertical keels 11 are fixedly connected to the embedded parts. The embedded parts are provided in multiple numbers. This part is a conventional structure in the prior art and will not be described in detail here. The horizontal keels 12 are arranged between two adjacent vertical keels 11, and both ends of the horizontal keels 12 are welded to the vertical keels 11. After the vertical keels 11 are fixedly installed according to the installation design requirements, the horizontal keels 12 are fixed, and the widths of the horizontal keels 12 and the vertical keels 11 are the same.

[0042] As Figure 2 、 6As shown, the bottom plate 21 is in a cross structure, and both ends of the bottom plate 21 along the length direction of the vertical keel 11 are riveted and fixed to the vertical keel 11 by rivets 5. Both ends of the bottom plate 21 along the length direction of the horizontal keel 12 are fixed to the horizontal keel 12 by bolts 6. The bolt 6 is an internal hexagonal bolt. And there are four angle-shaped parts 22 on the bottom plate 21, which are arranged in a circular array with the center of the bottom plate 21 as the center of the circle. The four angle-shaped parts 22 form a cross gap, and the plug-in part 3 is filled into the cross gap. The corner direction of each angle-shaped part 22 is consistent with the corner direction of the cross plane on the keel frame 1. The angle-shaped parts 22 are arranged at the corners of the stone plate 4 and are used to fix the corners of the stone plate 4. Specifically, the number of the angle-shaped parts 22 on the bottom plate 21 is not limited to four. In this example, the stone plate 4 is in a cube structure. Therefore, there are four angle-shaped parts 22 on the bottom plate 21, and every four of the mounting frames 2 distributed in a matrix are located at the four corners of the stone plate 4 and are used to fix the four corners of the stone plate 4.

[0043] As Figure 5 shown, an angle steel 7 is welded to the side surface of the vertical keel 11. A through hole through which the bolt 6 passes is opened on the angle steel 7. The cross section of the horizontal keel 12 is angular. The horizontal keel 12 is attached to the angle steel 7, and the bolt 6 on the bottom plate 21 passes through the angle steel 7 and is fixedly connected to the vertical keel 11. The setting of the angle steel 7 improves the installation strength of the horizontal keel 12.

[0044] As Figure 2 、 3 As shown in FIGS. 6 and 7, the angle-shaped part 22 includes two plate parts 26 of an integral structure. The included angle between the two plate parts 26 is 0 - 180°. The included angle between the two plate parts 26 is determined according to the corner angle of the stone plate 4. In this example, the included angle between the two plate parts 26 is 90°. Elastic cantilevers 23 are respectively arranged on the two plate parts 26. The plug-in head 24 faces the inside of the angle-shaped part 22, that is, the plug-in head 24 faces one side of the stone plate 4. The angle-shaped part 22 is made of aluminum alloy or stainless steel, or can also be made of other alloy materials. And the included angle between the plug-in head 24 and the elastic cantilever 23 is less than 90°. In this way, when the stone plate 4 is pressed and installed, the elastic cantilever 23 can be pressed to move in the direction away from the stone plate 4. After the stone plate 4 is installed in place, the elastic cantilever 23 rebounds so that the plug-in head 24 is inserted into the plug-in slot 41 in the stone plate 4 to complete the fixation of the stone plate 4.

[0045] Of course, the included angle between the two plate parts 26 can also be 180°, that is, the angle-shaped part 22 is formed into a straight plate structure. In this way, the angle-shaped part 22 can be used to fix the side of the stone plate 4. In this case, only two angle-shaped parts 22 are needed for each mounting frame 2 to fix the side of the stone plate 4. This structure is suitable for stone plates 4 with larger sizes.

[0046] As Figure 7As shown in the figure, further, the connecting portion 25 between the plug connector 24 and the elastic cantilever 23 is an arc structure, and the elastic cantilever 23 is inclined towards the outside of the angle member 22. On the one hand, it facilitates the elastic cantilever 23 to rebound and swing. On the other hand, the arc structure processes the corner in a smooth transition form, reduces stress concentration, and improves the seismic resistance.

[0047] As Figure 2 , 6 shown, the plug-in member 3 is inserted into the cross gap in a cross structure. The plug-in member 3 includes an integral cross strip plate 31 and a cross plug-in plate 32. An embedding groove 33 is provided on the side of the cross plug-in plate 32. The embedding groove 33 matches the connecting portion 25 between the plug connector 24 and the elastic cantilever 23. After the plug-in member 3 is inserted into the cross gap, the connecting portion 25 is placed into the embedding groove 33, which can fix the plug-in member 3 without any auxiliary components. At the same time, due to the existence of the embedding groove 33, the distances of the front and back displacements of the plug connector 24 are different. Therefore, the depth length of the plug-in groove 41 is greater than the length of the plug connector 24. Of course, the width of the plug-in groove 41 should also be slightly greater than the thickness of the plug connector 24. The bottom of the cross plug-in plate 32 is a conical structure, and the minimum dimension of the conical structure is smaller than the minimum distance between the connecting portions 25 of the two elastic cantilevers 23 and the plug connector 24 in two adjacent angle members 22 on the bottom plate 21, which facilitates the insertion of the cross plug-in plate 32. And the height of the angle member 22 is less than the thickness of the stone plate 4, and the gaps between the adjacent stone plates 4 are sealed by the sealant 8, which ensures the integrity of the sealant 8. The sealant 8 is a weather-resistant silicone sealant or a polyurethane sealant, or it can also be other sealants. Embodiment

[0048] In this example, taking the installation structure of the stone curtain wall in Embodiment 1 as an example, the construction method of the installation structure of the stone curtain wall is specifically described, which includes the following steps:

The angle member 22 and the bottom plate 21 are welded according to the design. Grooves are opened on both sides of the corners of the stone plate 4 in the stone factory to form plug-in grooves 41;

[0050] S2. Transport the vertical keel 11, the horizontal keel 12, the mounting bracket 2 and the stone plate 4 to the construction site, and rivet and fix the two ends of the mounting bracket 2 to the vertical keel 11 through the riveting holes with rivets;

[0051] S3. Fix the vertical keel 11 to the embedded parts on the building according to the design, install the vertical keel 11, weld the horizontal keel 12 between two adjacent vertical keels 11 by welding, form a cross plane at the junction of the horizontal keel 12 and the vertical keel 11, and fix the bottom plate 21 to the horizontal keel 12 with bolts 6 to complete the installation of the curtain wall framework;

[0052] S4. Fill the insertion slot 41 of the stone panel 4 with structural adhesive. The structural adhesive is polyurethane structural adhesive or epoxy resin structural adhesive. Install the stone panel 4 in the space surrounded by four mounting brackets 2 distributed in a matrix, so that the stone panel 4 fits against the bottom plate 21 in the mounting bracket 2, and the insertion head 24 is inserted into the insertion slot 41 in the stone panel 4 to complete the pre-installation of the stone panel 4;

[0053] S5. Insert the connector 3 between two angle members 22 in the mounting bracket 2. The connector 3 abuts against the connecting part 25 of the elastic cantilever 23 and the insertion head 24, and the connector 3 is clamped and fixed. The gap between adjacent stone panels 4 is sealed with sealant.

[0054] When it is necessary to replace the stone panel 4, only need to break and remove the original stone panel 4, take out the connector 3 at the corner of the stone panel 4, install the new stone panel 4 in the original position. After installation in place, insert the connector 3 to complete the replacement and maintenance of the stone panel 4. The maintenance is simple, and the maintenance cost and difficulty are low.

[0055] The working principle of the present invention is: The stone panel 4 is fixed by inserting and connecting with the insertion head 24 in the mounting bracket 2. At the same time, the angle member 22 can position the corner of the stone panel 4. During the construction process, there is no need for excessive manual docking between the stone panel 4 and the mounting bracket 2. The installation is convenient, and rapid installation can be achieved, which simplifies the construction process, greatly shortens the construction time, significantly improves the construction efficiency, can ensure the overall accuracy of the stone curtain wall, enhances the aesthetics and stability of the curtain wall. At the same time, the stable installation structure also greatly enhances the wind pressure resistance of the stone curtain wall, ensuring its safety in high-rise buildings; when a single stone panel 4 in the stone curtain wall has problems or needs to be replaced, only need to disassemble the connector 3, without overall demolition, and the later maintenance work is more convenient, greatly reducing the maintenance cost and difficulty.
