Technical Field

[0001] The present application relates to the technical field of stone curtain walls, and in particular to a second-line defense structure of a stone curtain wall. Background Art

[0002] In exterior wall decoration, the installation of stone curtain walls mainly adopts the dry hanging method, which is an installation method in which the stone is directly hung on the wall or hung on the steel frame without grouting and pasting.

[0003] At present, the installation of stone curtain walls mainly relies on the keel for support and fixation. First, the installation position and spacing of the curtain wall need to be determined according to the design drawings, and then the keel is installed as required. The installation of the keel must be firm and reliable. It is necessary to use an electric drill to pre-drill holes in the wall, and then use fixings to fix the keel to the wall; then it is stone processing and installation. According to the design requirements, the stone is cut into the required size and shape using a cutting machine, and then, according to the needs, the stone is grooved, punched, etc., so as to facilitate the connection and fixation with the keel; stone installation is an important part of stone curtain wall construction. First, the stone needs to be placed on the keel in the order and position required by the design. Then, the stone is fixed to the keel with fixings. Common fixing methods include stainless steel hangers, aluminum alloy hangers, back bolts, etc. The back bolt stone curtain wall is fixed with a stainless steel back bolt and an aluminum alloy hook, and then the aluminum alloy hook is fixed to the hook seat to achieve stone fixation.

[0004] However, during long-term use, the fixing strength may decrease due to corrosion, aging and other reasons, thus causing safety problems. That is, as the years of use increase, the stone may become loose or even fall and injure people. Therefore, it is urgent to design an installation structure that can effectively improve the safety of the stone curtain wall system on the original basis. Summary of the invention

[0005] In order to improve the safety of the stone curtain wall system, the present application provides a second line of defense structure for the stone curtain wall.

[0006] The present application provides a stone curtain wall second line of defense structure, which adopts the following technical solutions: A second-line defense structure of a stone curtain wall comprises a keel frame arranged on a wall, the keel frame is provided with a plurality of first fixing members for fixing a stone plate, the keel frame is provided with a protection component for providing a second line of protection for the stone plate, the protection component comprises: A fixing block, wherein the fixing block is arranged on the keel frame; A plug-in block, the plug-in block is plugged and arranged on the fixed block from top to bottom; A support rod, wherein the support rod is rotatably mounted on a side wall of the plug-in block, an end of the support rod away from the plug-in block is rotatably mounted on a stone plate, the support rod is tilted and the height of the contact point between the support rod and the stone plate is higher than the height of the contact point with the plug-in block, and the length of the support rod (43) is retractable.

[0007] By adopting the above technical solution, when the first fixed defense line is damaged and causes the stone slab to loosen or even fall, the stone slab drives the support rod to extend a certain length and rotate on the plug-in block, the fixed block fixes the plug-in block, and finally the fallen stone slab is suspended by the support rod, thereby preventing the stone slab from continuing to fall, reducing the probability of injury caused by the falling stone slab and improving the safety of the stone curtain wall system.

[0008] Furthermore, a first elastic rope is arranged on the keel frame, and the other end of the first elastic rope is arranged on the top of the stone board close to the wall. The connection point of the first elastic rope and the keel frame is equal to or higher than the connection point of the first elastic rope and the stone board, and the first elastic rope can undergo elastic deformation.

[0009] By adopting the above technical solution, during the falling process of the stone slab, the first elastic rope undergoes elastic deformation, thereby reducing the falling speed of the stone slab. At the same time, if the stone slab falls completely, the first elastic rope drives the stone slab to rotate a certain angle, so that after the support rod hangs and fixes the stone slab, the top of the stone slab is closer to the wall, which makes it easy to guide rainwater or impurities on the surface of the stone slab out of the stone curtain wall, effectively reducing the probability of rainwater or impurities falling into the gap between the stone curtain wall and the wall.

[0010] Furthermore, the fixing block is provided with a limit block for limiting the maximum downward rotation angle of the support rod, and the fixing block is provided with a locking piece for locking the plug-in block.

[0011] By adopting the above technical solution, when the stone plate drives the support rod to rotate downward, the locking piece prevents the plug-in block from moving, and the limit block supports the bottom of the support rod, thereby reducing the probability of the support rod colliding with the bottom stone plate.

[0012] Furthermore, the stone plate is provided with a connection assembly for rotationally connecting with the support rod, and the connection assembly includes: a first back bolt, the first back bolt being arranged on the stone plate; A connecting block, the connecting block is pressed against the stone plate and is locked on the first back bolt through a nut; The rotating head is arranged on the connecting block and is rotatably connected with the supporting rod through a rotating bolt.

[0013] By adopting the above technical solution, the first back bolt is first fixedly installed on the stone board, and then the connecting block is installed on the first back bolt and fixed by bolts. Finally, the support rod is rotated and inserted into the rotating head and rotationally connected by rotating the bolts, so as to realize the rotational connection between the support rod and the stone board.

[0014] Furthermore, the stone plate and the keel frame may be connected via a plurality of groups of cables, and the stone plate and the keel frame may be connected via a plurality of groups of cables and / or protective components.

[0015] By adopting the above technical solution, the stone panels and the keel frame are provided with a second layer of protection by using any one of a plurality of groups of cables, protective components, or a plurality of groups of cables and protective components, thereby improving the safety of the stone curtain wall system.

[0016] Furthermore, the length of the cable is greater than the distance between the connection point between the cable and the stone plate and the connection point between the cable and the keel frame.

[0017] By adopting the above technical solution, the cable can be tightened only when the stone slab falls to a certain extent. When the cable is tightened, the fallen stone slab is hoisted. At this time, the stone slab is out of its original position, which plays a good warning role and makes it easy for the staff to discover the falling of the stone slab in time and carry out repairs and replacements.

[0018] Furthermore, the cable is detachably arranged on the stone plate through a second fixing member, and the second fixing member includes: a second back bolt, the second back bolt being arranged on the stone plate; A metal gasket is sleeved on the second back bolt and fixed by a nut, and the cable is welded on the metal gasket.

[0019] By adopting the above technical solution, the second back bolt is pre-fixed and installed on the specified position of the stone plate, and then the metal gasket welded with the cable is sleeved on the second back bolt, and finally the metal gasket is fixed to the second back bolt by bolts, so as to fix the cable to the stone plate, which is convenient for the subsequent cable to lift and fix the fallen stone plate.

[0020] Furthermore, when the second line of protection between the stone slab and the keel frame is connected only by multiple sets of cables, a second elastic rope is provided on the keel frame, and the second elastic rope can undergo elastic deformation. When the stone slab falls, the second elastic rope undergoes elastic deformation and reduces the falling speed of the stone slab. The second elastic rope cooperates with the cable to lift the fallen stone slab.

[0021] By adopting the above technical solution, when the stone slab falls, the multiple groups of cables are in an untensioned state, and the second elastic rope undergoes elastic deformation, thereby providing an upward force on the fallen stone slab, reducing the falling speed of the stone slab, and thereby reducing the impact force of the stone slab on the cables when the cables are tightened. Finally, the fallen stone slab is hoisted and fixed by the second elastic rope and the multiple groups of cables.

[0022] Furthermore, a protection component is provided on the stone plate, and the protection component comprises: An adhesive layer, the adhesive layer being arranged on a side of the stone slab close to the wall; A metal protective net is arranged on the stone plate through an adhesive layer.

[0023] By adopting the above technical solution, the metal protective net is fixed on the stone slab through the adhesive layer. The adhesive layer reduces the probability of water and other harmful substances invading the back of the stone. At the same time, the metal protective net and the adhesive layer cooperate with each other to effectively improve the structural strength of the stone, making the stone slab not easy to break and reducing the probability of the stone slab breaking and falling when it falls.

[0024] Furthermore, a protective layer is provided on the side of the metal protective net away from the stone plate, and the protective layer is made of anti-corrosion paint.

[0025] By adopting the above technical solution, the protective layer can effectively reduce the probability of the metal protective mesh being corroded during long-term use, thereby extending the service life of the metal protective mesh. At the same time, the protective layer can also protect the back of the stone slab from environmental factors, further enhancing the durability of the stone.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the first fixed line of defense is damaged and causes the stone slab to loosen or even fall, the stone slab drives the support rod to extend and rotate on the plug-in block, and finally the fallen stone slab is hoisted by the support rod to prevent the stone slab from falling further. At the same time, due to the inclined setting of the support rod, the stone slab stops falling and moves away from its original position, which is convenient for the staff to find and repair and replace it in time, thereby improving the safety of the stone curtain wall system.

[0027] 2. Through the cooperation between the cables and the support rods, multiple lifting protections are provided for the falling stone slabs, thereby reducing the probability of injury caused by the falling stone slabs and improving the safety of the stone curtain wall system.

[0028] 3. When the stone slab falls, the second elastic rope undergoes elastic deformation, thereby buffering the falling speed of the stone slab. As the stone slab continues to fall, the cable is eventually tightened to suspend the stone slab. At the same time, the second elastic rope is pulled to bring the top of the stone slab closer to the wall, reducing the probability of the falling stone slab hitting the bottom stone slab, reducing the probability of injury caused by the falling stone slab, and improving the safety of the stone curtain wall system.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-9 This application is described in further detail.

[0032] The embodiment of the present application discloses a two-line defense structure of a stone curtain wall.

[0033] Example 1 Reference Figure 1 , Figure 2 and Figure 3 A second-line defense structure of a stone curtain wall includes a keel frame 11 arranged on a wall 1, a plurality of first fixing members 2 for fixing a stone plate 3 are arranged on the keel frame 11, and a protection component 4 for providing a second line of protection for the stone plate 3 is arranged on the keel frame 11.

[0034] Reference Figure 1 and Figure 2 , determine the installation position and spacing of the curtain wall on the wall 1 according to the design drawings, then use an electric drill to pre-drill holes on the wall 1, and then fix the keel frame 11 on the wall 1. Before installing the stone board 3, multiple groups of first fixing members 2 are fixedly installed on the keel frame 11 by bolts. The first fixing members 2 include angle steels 21 and clamping members 22. The angle steels 21 are tightly installed on the keel frame 11 and fixed by multiple groups of first fixing bolts, so as to fix the angle steels 21 on the keel frame 11; then the clamping members 22 are pressed against the upper surface of the angle steels 21, and multiple groups of second fixing members are used to fix the angle steels 21 on the keel frame 11. The bolts fix the clamping piece 22 on the angle steel 21; clamping grooves that cooperate with the clamping piece 22 are opened on the opposite ends of the stone panels 3. During installation, the bottom of the clamping piece 22 is inserted into the top clamping groove of the bottom stone panel 3 among the adjacent stone panels 3, and then the upper stone panel 3 is placed on the bottom stone panel 3 and the clamping piece 22 is inserted into the bottom clamping groove of the upper stone panel 3, so as to clamp and fix the opposite end of the adjacent stone panels 3, and multiple groups of first fixing members 2 cooperate with each other to fix multiple groups of stone panels 3 and form the first fixed defense line of the stone curtain wall.

[0035] Reference Figure 3 Since the first fixed defense line is under stress for a long time during the use of the stone curtain wall, as the service life increases, the first fixing member 2 is prone to corrosion, aging and other reasons, which may lead to a decrease in its fixing strength, thereby causing the stone to loosen or even fall and injure people; in order to reduce the occurrence of such situations, when the first fixed defense line of the stone slab 3 is constructed, a protective component 4 for providing a second layer of protection for the stone slab 3 is arranged on the keel frame 11 to reduce the probability of the stone slab 3 falling and injuring people.

[0036] Reference Figure 4 , Figure 5 and Figure 6 Specifically, the protection assembly 4 includes a fixed block 41, a plug-in block 42 and a support rod 43, the fixed block 41 is fixedly installed on the keel frame 11 by bolts; the plug-in block 42 is plugged and installed on the fixed block 41 from top to bottom, wherein the fixed block 41 is provided with a plug-in slot 411 for facilitating the plug-in of the plug-in block 42; the support rod 43 is rotatably installed on the side wall of the plug-in block 42, and one end of the support rod 43 away from the plug-in block 42 is rotatably set on the stone plate 3, and a rotation slot 412 is provided on the fixed block 41 for facilitating the rotation of the support rod 43; the length of the support rod 43 Retractable, the support rod 43 includes a main rod 431, a sliding rod 432 and a limiter 433, wherein the sliding rod 432 is slidably arranged in the main rod 431, the limiter 433 is fixedly mounted on the sliding rod 432 and slides in the main rod 431, and the limiter 433 is used to limit the maximum sliding distance of the sliding rod 432, thereby limiting the maximum telescopic amount of the support rod 43; wherein the end of the main rod 431 away from the sliding rod 432 is rotatably mounted on the plug-in block 42, and the end of the sliding rod 432 away from the main rod 431 is rotated to be arranged on the stone plate 3.

[0037] Reference Figure 5 and Figure 6 When the stone slab 3 is fixedly installed, the support rod 43 is inclined and in a shortened state. The height of the contact point between the support rod 43 and the stone slab 3 is higher than the height of the contact point between the support rod 43 and the plug-in block 42. Finally, when the stone slab 3 loosens and falls, the support rod 43 extends and rotates to make the stone slab 3 move away from its original position. Then, under the action of the support rod 43, the stone slab 3 is prevented from falling and injuring people. At the same time, the stone slab 3 is moved away from its original position, which serves as a good warning, making it easy for the staff to promptly discover the looseness of the stone slab 3 and replace it in time.

[0038] Reference Figure 5 and Figure 6A connecting assembly 5 for rotatably connecting with the support rod 43 is provided on the stone plate 3, and the connecting assembly 5 includes a first back bolt 51, a connecting block 52 and a rotating head 53, wherein the first back bolt 51 is fixedly mounted on the stone plate 3; the connecting block 52 is pressed against the stone plate 3 and locked on the first back bolt 51 through a nut; the rotating head 53 is fixedly mounted on the end of the connecting block 52 away from the stone plate 3, and the rotating head 53 is rotatably connected to the support rod 43 through a rotating bolt 54, wherein the rotating axis of the support rod 43 and the plug-in block 42 and the axis of the rotating bolt 54 are parallel to each other.

[0039] Reference Figure 3 , Figure 5 and Figure 6 A first elastic rope 6 is also fixedly installed on the keel frame 11, and the other end of the first elastic rope 6 is fixedly installed on the top of the stone board 3 close to the wall 1 through a back bolt. The connection point between the first elastic rope 6 and the keel frame 11 is equal to or higher than the connection point between the first elastic rope 6 and the stone board 3, and the first elastic rope 6 can undergo elastic deformation.

[0040] Reference Figure 3-Figure 8 Specifically, since the loosening of the stone slab 3 includes loosening and falling at the top first or loosening and falling at the bottom first, when the stone slab 3 loosens and falls at the top first, the stone slab 3 drives the support rod 43 to extend and rotate, and finally drives the first elastic rope 6 to undergo elastic deformation, thereby reducing the descending speed of the stone slab 3. At the same time, the inclined stone slab 3 plays a good warning role, which is convenient for the staff to carry out timely maintenance and replacement; when the stone slab 3 loosens and falls at the bottom first, the stone slab 3 drives the support rod 43 to rotate and extend .... The elastic rope 6 undergoes elastic deformation, thereby reducing the descending speed of the stone slab 3. At the same time, the stone slab 3 is driven to rotate a certain angle through the pulling of the first elastic rope 6, and finally the top end of the stone slab 3 is closer to the wall 1, so that rainwater or impurities on the surface of the stone slab 3 are easily discharged out of the stone curtain wall. Before the workers find that the stone slab 3 is loose and replace it, the probability of rainwater or impurities falling into the gap between the stone curtain wall and the wall 1 is effectively reduced; at the same time, the probability of the bottom of the falling stone slab 3 hitting the stone slab 3 below is also reduced.

[0041] Reference Figure 5 and Figure 6In order to reduce the probability that the stone slab 3 drives the support rod 43 to rotate and hit the stone slab 3 below, a limit block 44 is fixedly installed on the fixed block 41 to limit the maximum downward rotation angle of the support rod 43, and the limit block 44 is used to cover part of the rotation groove 412; at the same time, a locking piece 45 for locking the plug-in block 42 is fixedly installed on the top of the fixed block 41; specifically, when the stone slab 3 falls, the stone slab 3 drives the support rod 43 to rotate on the plug-in block 42, and at the same time the first elastic rope 6 buffers the falling speed of the stone slab 3, and finally the support rod 43 contacts with the limit block 44 and stops the support rod 43 from continuing to rotate through the limit block 44, and the locking block prevents the plug-in block 42 from sliding on the fixed block 41, so that the position of the stone slab 3 is finally fixed; the limit block 44 of this embodiment is provided with a buffer pad on one end close to the support rod 43.

[0042] Reference Figure 7 In order to improve the strength of the stone slab 3, a protective component 7 is also provided on the stone slab 3. The protective component 7 includes an adhesive layer 71 and a metal protective net 72. The adhesive layer 71 is fixedly installed on the side of the stone slab 3 close to the wall 1; the metal protective net 72 is fixedly installed on the stone slab 3 through the adhesive layer 71. The structural strength of the stone is significantly improved by the metal protective net 72, so that the stone slab 3 is not easily damaged during processing, warehousing, arranging, transportation and construction attachment operations, and the probability of debris falling when the stone slab 3 falls is also effectively reduced; the adhesive layer 71 of this embodiment is made of epoxy resin, and the adhesive layer 71 can also reduce the probability of water and other harmful substances invading the back of the stone slab 3. The metal protective net 72 is made of stainless steel wire mesh.

[0043] Reference Figure 7 In order to ensure the stability of the metal protection net 72, a protective layer 73 is provided on the side of the metal protection net 72 away from the stone plate 3. The protective layer 73 is made of anti-corrosion paint. The protective layer 73 effectively protects the back of the stone plate 3, reduces the probability of environmental factors affecting the stone plate 3, and ultimately improves the durability of the stone plate 3.

[0044] The working principle of Example 1 of the present application is: When the first fixed defense line is damaged and causes the stone slab 3 to loosen or even fall, the stone slab 3 drives the support rod 43 to extend and rotate on the plug-in block 42, and finally the fallen stone slab 3 is hoisted by the support rod 43, thereby preventing the stone slab 3 from continuing to fall. At the same time, since the support rod 43 is tilted and retractable, the stone slab 3 stops falling and moves away from its original position, making it easy for the staff to find and repair and replace it in time, thereby improving the safety of the stone curtain wall system.

[0045] Example 2 Reference Figure 8The difference between this embodiment and embodiment 1 is that the stone plate 3 and the keel frame 11 are also connected by multiple groups of cables 8, and the stone plate 3 and the keel frame 11 are commonly connected by multiple groups of cables 8 and the protective component 4, wherein the cable 8 is detachably mounted on the stone plate 3 through the second fixing member 81, and the second fixing member 81 includes a second back bolt 811 and a metal gasket 812, and the second back bolt 811 is fixedly mounted on the side of the stone plate 3 close to the wall 1; the metal gasket 812 is sleeved on the second back bolt 811, and then the metal gasket 812 is fixedly mounted on the second back bolt 811 through a nut, one end of the cable 8 is welded and fixed on the metal gasket 812, and at the same time, the connection point of the cable 8 and the metal gasket 812 is treated with anti-corrosion to improve the connection strength between the cable 8 and the stone plate 3; the cable 8 of this embodiment adopts a stainless steel cable 8.

[0046] Reference Figure 8 and Fig. 9 The height of the connection point between the cable 8 and the keel frame 11 is higher than the connection point between the cable 8 and the stone slab 3, which makes it easy for the cable 8 to lift the fallen stone slab 3; the length of the cable 8 is greater than the distance between the connection point between the cable 8 and the stone slab 3 and the connection point between the cable 8 and the keel frame 11, so that when the stone slab 3 falls and the cable 8 is tightened, the position of the stone slab 3 has deviated from the original position, which makes it easy for the staff to promptly discover the falling of the stone slab 3 and carry out timely repair and replacement.

[0047] Reference Figure 8 and Fig. 9 , the length of the cable 8 can be determined according to the installation requirements, specifically: a. The cable 8 is short. When the cable 8 is tightened, the support rod 43 has not yet rotated to the maximum angle value or reached the maximum elongation state. At this time, the lifting force on the stone slab 3 is mainly provided by the cable 8. The support rod 43 only assists in controlling the falling trajectory of the stone slab 3 to reduce the probability of the stone slab 3 hitting the bottom stone slab 3 when it falls. At the same time, when the cable 8 is damaged, the stone slab 3 moves a certain distance again, and the stone slab 3 is lifted and fixed by the support rod 43; b. The length of the cable 8 is medium. When the cable 8 is tightened, the support rod 43 has just rotated to the maximum angle value and is in the maximum elongation state. At this time, the lifting force on the stone plate 3 is provided by the cable 8 and the support rod 43, which reduces the probability of damage to the cable 8 or the support rod 43; c. The cable 8 is relatively long. When the support rod 43 rotates to the maximum angle and is in the maximum elongation state, the cable 8 is still not tightened. At this time, the lifting force on the stone slab 3 is mainly provided by the support rod 43. At the same time, when the support rod 43 is damaged, the stone slab 3 moves a certain distance again, and the cable 8 is used to lift and fix the stone slab 3.

[0048] The working principle of Example 2 of the present application is: The cables 8 and the support rods 43 cooperate with each other to provide multiple lifting protections for the falling stone slabs 3, thereby reducing the probability of injury caused by the falling stone slabs 3 and improving the safety of the stone curtain wall system.

[0049] Example 3 Reference Fig.10 The difference between this embodiment and embodiment 2 is that the second line of protection between the stone slab 3 and the keel frame 11 is connected only by multiple groups of cables 8. A second elastic rope 9 is also provided on the keel frame 11. The second elastic rope 9 can undergo elastic deformation. The height of the connection point between the second elastic rope 9 and the stone slab 3 is higher than the height of the connection point between the cable 8 and the stone slab 3. The length value of the cable 8 can be determined according to the installation requirements. The length values ​​of multiple groups of cables 8 on the same stone slab 3 are the same. In this embodiment, two groups of cables 8 are provided on the same stone slab 3, and the heights of the connection points of the two groups of cables 8 and the stone slab 3 are flush with each other.

[0050] Reference Fig.10 When the stone slab 3 is not loose, the second elastic rope 9 is in a taut but undeformed state. When the stone slab 3 is loose and falls, the second elastic rope 9 is elastically deformed under the gravity of the stone slab 3, thereby providing tension to the stone slab 3, and finally reducing the falling speed of the stone slab 3, which is convenient for the impact force of the stone slab 3 on the cable 8 when the subsequent cable 8 is tightened; at the same time, since the height of the connection point between the second elastic rope 9 and the stone slab 3 is higher than the height of the connection point between the cable 8 and the stone slab 3, the top of the stone slab 3 is closer to one side of the wall 1, reducing the probability of the falling stone slab 3 hitting the bottom stone slab 3; it is also convenient for the staff to more easily see the risk of the stone slab 3 falling, and to repair and replace the stone slab 3, reducing the probability of the stone slab 3 falling and injuring people, and improving the safety of the stone curtain wall system.

[0051] The working principle of Example 3 of the present application is: When the stone slab 3 falls, the second elastic rope 9 undergoes elastic deformation, thereby buffering the falling speed of the stone slab 3. As the stone slab 3 continues to fall, the cable 8 is eventually tightened to suspend the stone slab 3. At the same time, the second elastic rope 9 pulls the top of the stone slab 3 closer to the side of the wall 1, reducing the probability of the falling stone slab 3 hitting the bottom stone slab 3, reducing the probability of the stone slab 3 falling and injuring people, and improving the safety of the stone curtain wall system.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
