[0002] As a common decorative material for modern building facades, stone curtain walls are widely used in the exterior wall design of high-rise buildings, commercial buildings and public facilities due to their excellent aesthetic effects, durability and weather resistance. Stone itself has a natural texture and is not easy to fade, which can provide a stable visual effect in the building appearance.

[0003] The installation structure of stone curtain wall usually adopts dry hanging method, that is, using metal hangers to fix the stone on the building structure instead of directly sticking it with cement. The dry hanging method includes hanger dry hanging structure, back bolt dry hanging structure and keel + hanger system. The dry hanging method is widely used in high-rise buildings due to its safety and durability. However, the existing dry hanging method also has some disadvantages: 1) During the construction of the traditional stone curtain wall dry hanging installation structure, the connection method between the installation bracket and the stone plate is relatively complicated, and often requires manual docking. Position deviation is prone to occur during the installation process, making it difficult to control the installation accuracy, affecting the overall curtain wall effect and safety; 2) The installation process requires lifting and precise docking piece by piece. The entire installation process takes a long time, with low construction efficiency and high installation difficulty. Safety hazards often occur during the construction process, increasing the risk of construction; 3) Once the stone slab is damaged or needs to be replaced, the traditional dry hanging installation structure lacks a convenient maintenance design, making the subsequent maintenance work complicated and costly, increasing the difficulty of maintenance.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] Combination Figures 1 to 8The present embodiment is described. The present embodiment provides a stone curtain wall installation structure, which includes a keel frame 1, a mounting frame 2, a plug-in component 3 and a stone plate 4. The keel frame 1 is fixedly connected to the building exterior wall through embedded components. 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 a plurality of angle pieces 22. The angle pieces 22 are symmetrically welded to the bottom plate 21 in pairs. The angle pieces 22 have elastic cantilevers 23. The free ends of the elastic cantilevers 23 are bent to form plug-in components 24. The connector 3 is used to be inserted between the two angle pieces 22 and the connector 3 abuts against the connecting portion 25 of the elastic cantilever 23 and the plug connector 24. A plug groove 41 is provided on the corner side of the stone plate 4, and the plug groove 41 matches the plug connector 24. The stone plate 4 is placed on the inner side of the matrix-distributed angle pieces 22, and the inner surface of the stone plate 4 abuts against the bottom plate 21. During the specific installation, a rubber pad can also be attached to the upper surface of the bottom plate 21 to improve the seismic resistance of the stone plate 4. After the stone plate 4 is installed in place, the plug connector 24 is plugged into the plug groove 41.

[0021] like Figure 4-5 As shown, the keel frame 1 includes a vertical keel 11 and a transverse keel 12. The vertical keel 11 is a square tube structure, and the transverse keel 12 is a square tube structure or an angular steel bar. In this example, the transverse keel 12 is a right-angle steel bar. The vertical keel 11 is fixedly connected to the embedded parts. The embedded parts are provided in multiple numbers. This part is an existing conventional structure and is not described in detail here. The transverse keel 12 is provided between two adjacent vertical keels 11 and both ends of the transverse keel 12 are welded to the vertical keels 11. The transverse keel 12 is fixed after the vertical keel 11 is fixedly installed as required by the installation design, and the width of the transverse keel 12 is consistent with that of the vertical keel 11.

[0022] like Figure 2 , 6 As shown, the bottom plate 21 is a cross structure, and the two 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, and the two 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, and the bolts 6 are hexagon socket bolts, and the angle pieces 22 on the bottom plate 21 are set to four and distributed in a circular array with the center of the bottom plate 21 as the center of the circle, and the four angle pieces 22 form a cross gap, and the connector 3 is filled in the cross gap, and the corner direction of each angle piece 22 is consistent with the corner direction of the cross plane on the keel frame 1, and the angle piece 22 is set at the corner of the stone plate 4, and is used to fix the corner of the stone plate 4. Specifically, the corner pieces 22 on the base plate 21 are not limited to four. In this example, the stone plate 4 is a cube structure. Therefore, the corner pieces 22 on the base plate 21 are set to four, and every four matrix-distributed mounting frames 2 are distributed at the four corners of the stone plate 4 to fix the four corners of the stone plate 4.

[0023] like Figure 5As shown, an angle steel 7 is welded to the side of the vertical keel 11, and a through hole for the bolt 6 to pass through is opened on the angle steel 7. The cross-section of the transverse keel 12 is angular, and the transverse keel 12 is fitted with the angle steel 7. The bolts 6 on the bottom plate 21 pass through the angle steel 7 and are fixedly connected to the vertical keel 11. The provision of the angle steel 7 improves the installation strength of the transverse keel 12.

[0024] like Figure 2 , 3 As shown in Figures 6 and 7, the angle piece 22 includes two plates 26 of an integral structure, and the angle between the two plates 26 is 0-180°. The angle between the two plates 26 is determined according to the corner angle of the stone plate 4. In this example, the angle between the two plates 26 is 90°. The elastic cantilevers 23 are respectively arranged on the two plates 26, and the plug connector 24 faces the inner side of the angle piece 22, that is, the plug connector 24 faces the side of the stone plate 4. The material of the angle piece 22 is aluminum alloy or stainless steel, and can also be other alloy materials, and the angle between the plug connector 24 and the elastic cantilever 23 is less than 90°, so that when the stone plate 4 is pressed and installed, the elastic cantilever 23 can be pressed to move away from the stone plate 4. After the stone plate 4 is installed in place, the elastic cantilever 23 rebounds so that the plug connector 24 is inserted into the plug groove 41 in the stone plate 4 to complete the fixation of the stone plate 4.

[0025] Of course, the angle between the two plates 26 can also be 180°, that is, the angle piece 22 is formed into a straight plate structure, so that the angle piece 22 can be fixed to the side of the stone plate 4. In this way, each mounting frame 2 only needs two angle pieces 22 to fix the side of the stone plate 4. This structure is suitable for stone plates 4 with larger sizes.

[0026] like Figure 7 As shown, further, the connecting portion 25 between the plug connector 24 and the elastic cantilever 23 is an arc-shaped structure, and the elastic cantilever 23 is inclined toward the outside of the angle piece 22. On the one hand, it is convenient for the elastic cantilever 23 to rebound and swing, and on the other hand, the arc-shaped structure handles the corner in the form of a smooth transition, thereby reducing stress concentration and improving shock resistance.

[0027] like Figure 2 , 6As shown, the plug-in connector 3 is inserted into the cross gap in a cross structure. The plug-in connector 3 includes a cross strip 31 and a cross plug-in plate 32 of an integrated structure. An embedding groove 33 is provided on the side of the cross plug-in plate 32. The embedding groove 33 and the plug-in connector 24 match the connecting portion 25 of the elastic cantilever 23. After the plug-in connector 3 is inserted into the cross gap, the connecting portion 25 is placed in the embedding groove 33, which can fix the plug-in connector 3 without any auxiliary components. At the same time, due to the existence of the embedding groove 33, the distance of the front and rear displacement of the plug-in connector 24 is different. Therefore, the depth of the plug-in groove 41 is greater than the length of the plug-in connector 24. Of course, the width of the plug-in groove 41 is also slightly greater than the thickness of the plug-in connector 24. The bottom of the cross plug-in plate 32 is a conical structure and the minimum size of the conical structure is smaller than the minimum distance between the two elastic cantilevers 23 in the two adjacent angle pieces 22 on the bottom plate 21 and the connecting portion 25 of the plug-in connector 24, which facilitates the insertion of the cross plug-in plate 32. The height of the angle piece 22 is smaller than the thickness of the stone plate 4, and the gaps between adjacent stone plates 4 are sealed by the sealant 8, thereby ensuring the integrity of the sealant 8. The sealant 8 is a weather-resistant silicone sealant or a polyurethane sealant, or other sealants. Example

[0028] This example takes the installation structure of the stone curtain wall in Example 1 as an example to specifically illustrate the construction method of the installation structure of the stone curtain wall, which includes the following steps: S1, the vertical keel 11, the horizontal keel 12 and the plug-in connector 3 in the keel frame 1 are produced in the factory, and the rivet holes are drilled on the vertical keel 11 according to the design requirements. The factory prepares the bottom plate 21 and the angle piece 22 in the mounting frame 2, and the elastic cantilever 23 and the plug-in connector 24 are prepared on the angle piece 22. The angle piece 22 and the bottom plate 21 are welded according to the design, and the two sides of the corner of the stone plate 4 are grooved in the stone factory to form the plug-in groove 41; S2, transport the vertical keel 11, the horizontal keel 12, the mounting frame 2 and the stone plate 4 to the construction site, and rivet the two ends of the mounting frame 2 through the rivet holes to fix them to the vertical keel 11; S3. According to the design, the vertical keel 11 is fixedly connected to the embedded parts on the building, the vertical keel 11 is installed, and the transverse keel 12 is welded between two adjacent vertical keels 11. The intersection of the transverse keel 12 and the vertical keel 11 forms a cross plane, and the bottom plate 21 is fixedly connected to the transverse keel 12 by bolts 6 to complete the installation of the curtain wall frame; S4, filling the plug-in slot 41 of the stone plate 4 with structural adhesive, the structural adhesive being polyurethane structural adhesive or epoxy resin structural adhesive, and installing the stone plate 4 in the space surrounded by four mounting frames 2 distributed in a matrix, so that the stone plate 4 fits with the bottom plate 21 in the mounting frame 2, and the plug connector 24 is plugged into the plug-in slot 41 in the stone plate 4, completing the pre-installation of the stone plate 4; S5. Insert the connector 3 between the two angle pieces 22 in the mounting frame 2, the connector 3 abuts against the connection portion 25 between the elastic cantilever 23 and the plug connector 24, and the connector 3 is clamped and fixed, and the gap between the adjacent stone panels 4 is sealed by a sealant.

[0029] When the stone plate 4 needs to be replaced, it is only necessary to break and dismantle the original stone plate 4, take out the connector 3 at the corner of the stone plate 4, install the new stone plate 4 in the original empty position, and after it is installed in place, insert the connector 3 to complete the replacement and maintenance of the stone plate 4. The maintenance is simple, and the maintenance cost and difficulty are low.

[0030] The working principle of the present invention is as follows: the stone plate 4 is fixed by the plug connector 24 in the mounting frame 2, and the angle piece 22 can position the corner of the stone plate 4. During the construction process, the stone plate 4 and the mounting frame 2 do not need too much manual docking. The installation is convenient and can be quickly installed, which simplifies the construction process, greatly shortens the construction time, and significantly improves the construction efficiency. It can ensure the overall accuracy of the stone curtain wall, improve 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 and ensures its safety in high-rise buildings. When a single stone plate 4 in the stone curtain wall has a problem or needs to be replaced, it only needs to remove the plug connector 3 without overall dismantling. The subsequent maintenance work is simpler, which greatly reduces the maintenance cost and difficulty.
