[0002] During the normal maintenance of stone curtain walls, it is necessary to repair the stone curtain walls or replace damaged stones;

[0003] Currently, there are the following options for stone curtain wall maintenance or stone replacement:

[0004] 1. For the maintenance of stone with straight seams (through seams at the top and bottom), the existing repair plan is to first change the stone hanger to 4 picks, then drill holes at the rear pick position of the stone, fill the holes with marble glue or stone AB glue, move the undamaged stone upwards during installation, and then install the new stone;

[0005] 2. For the maintenance of I-shaped stone joints, the existing repair plan is to move the two upper stones upward. If the gap between the stones is smaller than the overlap length of the stone hangers, it will lead to moving three or more stones for position adjustment.

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] like Figure 1-Figure 5 As shown, the utility model provides a stone maintenance and replacement pendant, comprising:

[0045] A position-adjustable fixing member 1 connected to a load-bearing beam 4;

[0046] The hanging part 2 is connected to the back of the replacement stone 3, and the hanging part 2 is suspended and connected with the fixing part 1.

[0047] In this embodiment, when replacing a stone, the hanging member 2 is connected to the back of the replacement stone 3. The construction workers remove the damaged stone and the original stone installation hanging member at the construction site, and connect the fixing member 1 to the load-bearing beam 4. The replacement stone 3 is hoisted to the construction site by a hoisting machine. The construction workers cooperate with the hoisting machine to move the replacement stone 3 so that the hanging member 2 on the back of the replacement stone 3 is suspended and connected to the fixing member 1. If the installation position of the replacement stone 3 is inaccurate, the hanging connection between the hanging member 2 and the fixing member 1 is released, the position of the fixing member 1 is adjusted, and the hanging connection between the hanging member 2 and the fixing member 1 is re-established. The accurate installation of the replacement stone 3 is achieved through the above process.

[0048] The hanging connection between the hanging member 2 and the fixing member 1 realizes the fixed connection between the replacement stone 3 and the load-bearing beam 4. When replacing a stone, there is no need to move other stones. The installation operation is simple and convenient, which helps to improve the construction efficiency.

[0049] By adjusting the connection position of the fixing member 1 on the load-bearing beam 4, the installation adjustment of the replacement stone 3 is achieved, ensuring that the replacement stone 3 is accurately installed.

[0050] like Figure 1 and Figure 3As shown, in an optional embodiment of the present invention, four hanging members 2 are provided, and the four hanging members 2 are respectively close to the four corners of the replaced stone 3; the fixing members 1 correspond to the hanging members 2 one by one.

[0051] In this embodiment, by respectively arranging four hanging parts 2 near the four corners of the replacement stone 3, and arranging fixing parts 1 corresponding to the hanging parts 2 on the load-bearing beam 4, the connection between the replacement stone 3 and the load-bearing beam 4 is achieved through the hanging connection between the hanging parts 2 and the fixing parts 1, which can ensure the installation stability of the replacement stone 3.

[0052] like Figure 2 As shown, in an optional embodiment of the present invention, the fixing member 1 is L-shaped, the horizontal portion of the fixing member 1 is connected to the load-bearing beam 4 in an adjustable manner, and the vertical portion of the fixing member 1 is penetrated by a hanging hole 11;

[0053] The suspension member 2 includes:

[0054] Stone back bolt 22, stone back bolt 22 is connected to the back of the replacement stone 3;

[0055] A suspension column 21 is formed at the end of the stone back bolt 22;

[0056] The positioning nut 23 is threadedly connected to the suspension column 21. Two positioning nuts 23 are provided, and a limiting cavity 24 is formed between the two positioning nuts 23. The width dimension of the limiting cavity 24 is adapted to the thickness dimension of the vertical part of the fixing member 1. The outer diameter dimension of the positioning nut 23 is smaller than the inner diameter dimension of the suspension hole 11.

[0057] In this embodiment, when the hanging member 2 is suspended and connected to the fixing member 1, the hanging column 21 and the positioning nut 23 are passed through the hanging hole 11 until the vertical portion of the fixing member 1 corresponds to the limiting cavity 24. Under the action of gravity, the replacement stone 3 is lowered so that the vertical portion of the fixing member 1 enters the limiting cavity 24. The two positioning nuts 23 are respectively located on both sides of the vertical portion of the fixing member 1 and positioned, thereby completing the hanging connection between the hanging member 2 and the fixing member 1, realizing the connection between the replacement stone 3 and the load-bearing beam 4, and completing the installation and fixation of the replacement stone 3. The overall operation is simple and convenient, ensuring the installation stability of the replacement stone 3 while improving construction efficiency.

[0058] In this embodiment, during the specific construction process, the two positioning nuts 23 are screwed and adjusted to adjust the position of the limiting cavity 24, ensuring that the limiting cavity 24 can accurately correspond to the vertical portion of the fixing member 1. After the installation of the replacement stone 3 is completed, the replacement stone 3 is flush with the surface of the other stones.

[0059] During the specific construction process, the width of the limiting cavity 24 is slightly larger than the thickness of the vertical part of the fixing member 1. After the installation of the replacement stone 3 is completed, the verticality of the replacement stone 3 is fine-tuned by filling supports between the replacement stone 3 and the two other adjacent stones above and below, so that the replacement stone 3 is flush with the surface of the other stones, ensuring the installation effect of the replacement stone 3.

[0060] like Figure 2 As shown, in an optional embodiment of the present invention, the suspension member 2 further includes:

[0061] The limiting nut 25 is threadedly connected to the suspension column 21, and the limiting nut 25 abuts against the positioning nut 23 away from the replacement stone 3.

[0062] In this embodiment, a limiting nut 25 is provided to limit the positioning nut 23 away from the replacement stone 3 to prevent it from moving, thereby ensuring the installation stability of the replacement stone 3.

[0063] like Figure 5 As shown, in an optional embodiment of the present invention, the hanging hole 11 includes:

[0064] A first through hole 111, wherein the inner diameter of the first through hole 111 is larger than the outer diameter of the positioning nut 23;

[0065] The second through hole 112 is connected to the first through hole 111 and is located below the first through hole 111 . The outer diameter of the second through hole 112 matches the outer diameter of the suspension column 21 .

[0066] In this embodiment, when the hanging member 2 is suspended and connected to the fixing member 1, the hanging column 21 and the positioning nut 23 are passed through the first through hole 111 until the vertical portion of the fixing member 1 corresponds to the limiting cavity 24. Under the action of gravity, the replacement stone 3 is lowered so that the vertical portion of the fixing member 1 enters the limiting cavity 24. At this time, the hanging column 21 enters the second through hole 112. Since the outer diameter of the second through hole 112 is compatible with the outer diameter of the hanging column 21, the hanging column 21 can be limited by the second through hole 112, thereby ensuring the installation stability of the replacement stone 3.

[0067] like Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, the stone maintenance and replacement pendant further includes:

[0068] A second mounting groove 41 is formed through the surface of the load-bearing beam 4 and extends along the length direction of the load-bearing beam 4;

[0069] A first mounting groove 12 is formed through the horizontal portion of the fixing member 1 and is perpendicular to the second mounting groove 41 ;

[0070] The mounting bolt 5 has an end portion that passes through the first mounting groove 12 and the second mounting groove 41 in sequence, and the end portion of the mounting bolt 5 is threadedly connected with the mounting nut 7 .

[0071] In this embodiment, when connecting the fixing member 1 to the load-bearing beam 4, the fixing member 1 is placed on the load-bearing surface so that the first mounting groove 12 and the second mounting groove 41 are perpendicular and connected, and the end of the mounting bolt 5 passes through the first mounting groove 12 and the second mounting groove 41 and is located below the load-bearing beam 4. The mounting nut 7 is threadedly connected to the end of the mounting bolt 5 so that the mounting nut 7 is in close contact with the load-bearing beam 4, thereby completing the connection between the fixing member 1 and the load-bearing beam 4.

[0072] When the installation position of the replacement stone 3 is not accurate, it is necessary to adjust the position of the fixing member 1. Loosen the mounting nut 7 and adjust the fixing member 1 along the first mounting groove 12. Figure 4 The position adjustment in the Y direction is realized by the second mounting groove 41. Figure 4 The position adjustment in the X direction is carried out by adjusting the position of the fixing member 1 on the surface of the load-bearing beam 4 so that the hanging member 2 can be accurately suspended with the fixing member 1, thereby ensuring the accurate installation of the replacement stone 3 and ensuring the installation quality.

[0073] like Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, the stone maintenance and replacement pendant further includes:

[0074] The pressing block 6 is located on the surface of the horizontal portion of the fixing member 1 , and the end of the mounting bolt 5 passes through the connecting hole 61 on the surface of the pressing block 6 .

[0075] In this embodiment, a pressure block 6 is provided to press the horizontal portion of the fixing member 1, and at the same time, the friction between the pressure block 6 and the horizontal portion of the fixing member 1 is utilized to achieve relative stability between the pressure block 6 and the fixing member 1, thereby ensuring the installation stability of the fixing member 1 and the installation stability of the replacement stone 3.

[0076] like Figure 2 As shown, in an optional embodiment of the present invention, the bottom surface of the pressing block 6 and the surface of the horizontal portion of the fixing member 1 are both provided with anti-slip grooves.

[0077] In this embodiment, by providing anti-slip grooves on the bottom surface of the pressing block 6 and the surface of the horizontal portion of the fixing member 1, the friction between the pressing block 6 and the horizontal portion of the fixing member 1 can be increased, thereby achieving relative stability between the pressing block 6 and the fixing member 1, ensuring the installation stability of the fixing member 1, and ensuring the installation stability of the replacement stone 3;

[0078] The anti-slip pattern in this embodiment adopts a tooth structure. In specific applications, the anti-slip pattern can be other structures that can increase the friction between the pressing block 6 and the horizontal part of the fixing member 1, which is not specifically limited here.

[0079] like Figure 2 As shown, in an optional embodiment of the present invention, the stone maintenance and replacement pendant further includes:

[0080] The pad 8 is located between the horizontal portion of the fixing member 1 and the load-bearing beam 4 , and the end of the mounting bolt 5 passes through the connecting groove 81 on the surface of the pad 8 .

[0081] In this embodiment, when the height of the hanging hole 11 is not suitable and the installation position of the replacement stone 3 is not accurate, the spacer 8 of different thicknesses can be replaced. Figure 2 The height of the fixing member 1 is adjusted in the middle Z direction, thereby adjusting the height of the hanging hole 11 to ensure that the replacement stone 3 is accurately installed.

[0082] like Figure 2 As shown, in an optional embodiment of the present invention, the connecting groove 81 extends along the width direction of the load-bearing beam 4 , and the connecting groove 81 passes through the side surface of the cushion block 8 .

[0083] In this embodiment, by extending the connecting groove 81 along the width direction of the load-bearing beam 4 and passing through the side of the pad 8, the pad 8 can be pulled out and inserted without removing the fixing member 1, which facilitates the disassembly, assembly and replacement of the pad 8, meets the height adjustment of the fixing member 1, and helps to improve construction efficiency.

[0084] The specific process of stone replacement:

[0085] Drill holes near the four corners of the back of the replacement stone 3, and try to ensure that the four holes are distributed in a rectangular shape;

[0086] The connection between the hanging column 21 and the replacement stone 3 is achieved through the stone back bolt 22 and the drill hole, so that the back of the replacement stone 3 near the four corners is connected to the hanging column 21;

[0087] Screw the positioning nuts 23 onto the hanging posts 21 so that the limiting cavities 24 formed by the positioning nuts 23 on the four hanging posts 21 correspond to each other. Screw the limiting nuts 25 onto the hanging posts 21 so that the positioning nuts 23 away from the replacement stone 3 are limited by the limiting nuts 25 to prevent them from moving.

[0088] Construction workers removed damaged stone and original stone installation pendants at the construction site;

[0089] The construction personnel place the pad 8 and the fixing member 1 on the surface of the load-bearing beam 4 in sequence, and place the pressing block 6 on the horizontal surface of the fixing member 1, so that the first mounting groove 12 is perpendicular to the second mounting groove 41, and the connecting groove 81 is perpendicular to the second mounting groove 41, and the first mounting groove 12, the second mounting groove 41 and the connecting groove 81 are correspondingly connected, and the connecting hole 61 is correspondingly connected to the first mounting groove 12. The end of the mounting bolt 5 is passed through the connecting hole 61, the first mounting groove 12, the connecting groove 81 and the second mounting groove 41 in sequence and is located below the load-bearing beam 4. The mounting nut 7 is threaded onto the end of the mounting bolt 5 so that the mounting nut 7 is in close contact with the load-bearing beam 4, completing the connection between the fixing member 1 and the load-bearing beam 4. The above process is used to realize the installation of the four fixing members 1, so that the fixing member 1 corresponds to the suspension member 2;

[0090] The replacement stone 3 is hoisted to the construction site by a hoisting machine. The construction personnel cooperate with the hoisting machine to move the replacement stone 3, so that the four suspension columns 21 and the positioning nuts 23 on the suspension columns 21 respectively pass through the corresponding first through holes 111, so that the vertical parts of the four fixing members 1 respectively correspond to the corresponding limit cavities 24. The replacement stone 3 is lowered by the hoisting machine, and the four suspension columns 21 respectively enter the corresponding second through holes 112, completing the suspension connection between the suspension member 2 and the corresponding fixing member 1;

[0091] The correct installation of the replacement stone 3 is determined by the horizontality and verticality of the edges of the replacement stone 3 and whether the front surface of the replacement stone 3 is flush with the other stones;

[0092] When the replacement stone 3 is not installed correctly, the replacement stone 3 is lifted by a lifting machine, so that the suspension column 21 is separated from the second through hole 112 and enters the first through hole 111, and the replacement stone 3 is pulled away from the load-bearing beam 4 until the suspension column 21 and the positioning nut 23 are completely separated from the first through hole 111, and the suspension connection between the suspension member 2 and the fixing member 1 is released, and the replacement stone 3 is removed. Adjust the fixing member 1 and the suspension member 2 according to the specific situation, as follows:

[0093] When the horizontality and verticality of the edge of the replaced stone 3 do not meet the construction requirements, loosen the mounting nut 7 and realize the fixing member 1 along the first mounting groove 12. Figure 4 The position adjustment in the Y direction is realized by the second mounting groove 41. Figure 4 The position adjustment in the X direction can realize the position adjustment of the fixing member 1 in the horizontal direction; by replacing the pads 8 of different thicknesses, the position of the fixing member 1 can be adjusted along the X direction. Figure 2 The height of the fixing member 1 is adjusted in the middle Z direction, thereby achieving the height adjustment of the hanging hole 11; the horizontal position and height adjustment of the fixing member 1 are achieved through the above adjustment method, and the replacement stone 3 is reinstalled; by adjusting the position of the fixing member 1, the horizontality and verticality of the edge of the replacement stone 3 meet the construction requirements, and the replacement stone 3 is accurately installed;

[0094] When the front surface of the replacement stone 3 is not flush with the other stones, the positioning nut 23 is screwed to adjust the position of the positioning nut 23 on the hanging column 21, thereby realizing the position adjustment of the limiting cavity 24 on each hanging column 21, and re-installing the replacement stone 3; by adjusting the position of the limiting cavity 24 on the hanging column 21, the front surface of the replacement stone 3 is made flush with the other stones; in the specific construction process, in order to facilitate the hanging connection between the hanging piece 2 and the fixing piece 1, the width of the limiting cavity 24 is slightly larger than the thickness of the vertical part of the fixing piece 1. After completing the installation of the replacement stone 3, the verticality of the replacement stone 3 is fine-tuned by filling supports between the replacement stone 3 and the two other adjacent stones above and below, so that the surface of the replacement stone 3 is flush with the surface of the other stones, ensuring the installation effect of the replacement stone 3;

[0095] The above process is used to achieve accurate installation of the replacement stone 3. The present application realizes the fixed connection between the replacement stone 3 and the load-bearing beam 4 through the hanging connection of the hanging part 2 and the fixing part 1. When replacing the stone, there is no need to move other stones. The installation operation is simple and convenient, which helps to improve construction efficiency. By adjusting the connection position of the fixing part 1 on the load-bearing beam 4 and the position of the upper limit cavity 24 on the suspension column 21, the installation adjustment of the replacement stone 3 is achieved to ensure that the replacement stone 3 is accurately installed.

[0096] The above is a preferred embodiment of the present invention.
