Description

Technical Field

[0001] This invention relates to the field of stone dry-hanging support technology, specifically a support limiting device for dry-hanging stone wall construction and its usage method. Background Technology

[0002] Dry-hanging stone cladding, also known as stone curtain wall or dry-hanging method, is a high-end construction technique widely used in modern building exterior wall decoration. It involves directly suspending stone onto the building structure surface using metal hangers to form a decorative surface layer.

[0003] When dry-hanging stone, it is usually necessary to open grooves on the top and bottom sides of the stone and support the stone by connecting the hanging parts to the grooves. When connecting, glue is also needed to fill the grooves to ensure the firmness of the connection between the hanging parts and the stone.

[0004] During the connection process between the hanger and the groove, the hanger and the groove are usually fitted with a clearance, meaning the groove size is slightly larger than the hanger size to ensure that the hanger can be smoothly inserted into the groove. However, in actual operation, the clearance between the hanger and the groove is very small, which can easily lead to installation errors. Harmful point or line contacts can easily form between the hanger and the groove, causing a sharp increase in local stress in the groove. This can lead to the groove breaking when the stone is under stress. Furthermore, since the groove is filled with glue, whether the glue fails after long-term use, or other situations cause the stone connection to loosen or the stone itself to be damaged, it is necessary to replace the individual stone pieces. This requires forceful destruction to remove the stone, which can also easily damage the grooves of adjacent slabs, resulting in a situation where "replacing one results in multiple losses". Summary of the Invention

[0005] The purpose of this invention is to provide a support and limiting device for dry-hanging stone wall construction and its usage method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support and limiting device for dry-hanging stone wall construction, comprising: a bracket; further comprising: a receiving plate, which is hollow and fixedly connected to the bracket, wherein a through groove and a first sliding groove are formed on the receiving plate, and a support hanger is slidably installed on the first sliding groove; a swing positioning mechanism, which is disposed within the support hanger, wherein symmetrically arranged support plates are connected to the swing positioning mechanism, and a locking limiting mechanism is disposed within the receiving plate, wherein the locking limiting mechanism can drive the support plate to perform a swinging action through the swing positioning mechanism, and perform a locking action on the support plate when the support plate abuts against the inner wall of the stone groove.

[0007] As a further aspect of the present invention: the sway positioning mechanism includes a second sliding groove formed in the support bracket, a movable plate movably disposed in the support bracket, and a guide block fixed on the movable plate that slides and engages with the second sliding groove; it also includes an elastic component and a follower component disposed in the support bracket and connected to the movable plate.

[0008] As a further embodiment of the present invention: the elastic component includes a guide post fixed inside the support bracket and inserted into the movable plate, a spring sleeved on the guide post, and the two ends of the spring abutting against the inner wall of the support bracket and the movable plate respectively.

[0009] As a further embodiment of the present invention: the follower component includes convex columns fixed to the side wall of the movable plate and arranged symmetrically, and a first hinge rod and a second hinge rod arranged symmetrically are hinged to the support bracket. The first hinge rod and the second hinge rod are respectively hinged to the support plate, and a slot is formed on the first hinge rod to slide and engage with the convex column.

[0010] As a further embodiment of the present invention: the end of the movable plate is inclined, and a limiting groove is formed on the inclined surface of the movable plate in a through manner.

[0011] As a further embodiment of the present invention: the locking and limiting mechanism includes a screw threadedly connected to the receiving plate, and a push plate rotatably mounted at the end of the screw and slidably connected to the receiving plate.

[0012] As a further embodiment of the present invention: the locking and limiting mechanism further includes limiting posts fixed on the push plate and arranged symmetrically, the limiting posts slidingly engaging with the limiting grooves, and a limiting plate fixed on the limiting posts that abuts against the inclined surface of the movable plate.

[0013] As a further aspect of the present invention: the end of the screw away from the push plate has an internal hexagonal groove for assisting the rotation of the screw.

[0014] As a further embodiment of the present invention: the bracket is fixed with a baffle for supporting and limiting the position of the stone.

[0015] A method for using a support and limiting device for dry-hanging stone wall construction includes the following steps: Step 1: Install the support bracket into the first slide groove; Step 2: Transfer the stone material with the groove that matches the support bracket onto the receiving plate, and insert the support bracket into the groove; Step 3: Under the action of the locking and limiting mechanism, the two support plates are controlled to swing by the swing positioning mechanism; Step 4: When the support plate is in contact with the inner wall of the stone groove, the stone is supported and positioned. At the same time, under the action of the locking and limiting mechanism, the position of the support plate is locked by the swing positioning mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Before stone installation, the present invention eliminates the need for precise alignment of the support brackets and the groove; the groove can simply be fitted onto the support brackets and support plate. This improves the error tolerance during installation and eliminates problems such as groove edge cracking and scratches caused by misalignment. Furthermore, during subsequent installation, the support plate can move from a retracted state to an extended state, ensuring uniform contact between the support plate and the two side walls of the groove. This ensures even stress distribution on the stone. In this way, the slight eccentricity between the brackets and the groove during traditional installation avoids the problem of stress concentration caused by the slight eccentricity between the brackets and the groove, where the load is not symmetrically borne by the groove but rather by line support between the brackets and the groove.

[0017] After being positioned by the center, the stone can move smoothly to the position where it fits against the baffle. Since the stone is installed, its force is directed towards the wall where the vertical keel is installed, that is, towards the baffle. With the double cooperation of the baffle and the support plate, the support force on the stone can be further increased, so as to avoid the problem that when the stone is under stress, the load generated is entirely applied to the support plate and the groove, causing the groove to break due to stress.

[0018] To remove or replace the stone, simply reverse the screw to separate the limiting post and limiting plate from the limiting groove and the movable plate, respectively. The spring will then release, causing the movable plate to return to its end of its stroke, away from the support bracket. At this point, the stone can be detached from the receiving plate and moved by the groove, which in turn moves the support bracket. The support bracket will then move the movable plate, which, under the action of its inclined surface, will smoothly detach from the groove. In this way, the dry-hanging stone can be quickly disassembled and replaced without the need for tools or forceful destruction. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0023] Please see Figures 1-10In this embodiment of the invention, a support and limiting device for dry-hanging stone wall construction includes: a vertical keel 1 and a horizontal keel 2 fixed on the vertical keel 1, with a bracket 3 fixed on the horizontal keel 2; it also includes: a receiving plate 5, which is hollow and fixedly connected to the bracket 3, the receiving plate 5 having a through groove 501 and a first sliding groove 502, with a support hanger 10 slidably installed on the first sliding groove 502; and a swing positioning mechanism disposed within the support hanger 10, with symmetrically arranged support plates 16 connected to the swing positioning mechanism, and a locking limiting mechanism disposed within the receiving plate 5, the locking limiting mechanism being able to drive the support plate 16 to perform a swing action through the swing positioning mechanism, and locking the support plate 16 when it abuts against the inner wall of the stone groove.

[0024] The bracket 3 is fixed with a baffle 4 for supporting and limiting the position of the stone.

[0025] Specifically, when dry-hanging stone, it is necessary to support and limit the stone. During construction, the support bracket 10 can be installed in the first sliding groove 502. Under the action of the swing positioning mechanism, the distance between the two support plates 16 and the support bracket 10 is minimized, meaning the two support plates 16 are in a retracted state, and the distance between the two support plates 16 is less than the groove formed by the sidewall of the stone. Therefore, when the stone is transported and placed on the receiving plate 5, the two support plates 16 can smoothly enter the groove. At this time, the movement of the locking and limiting mechanism can be controlled, and the swing positioning mechanism can be used to achieve this. The mechanism drives the two support plates 16 to swing, and when the support plates 16 abut against the side wall of the stone groove, the stone is centered and positioned, so that one side of the outer wall of the stone abuts against the baffle 4. The support plates 16 also lock the position of the stone through the groove. At the same time, the locking and limiting mechanism will lock the position of the support plates 16 through the swing positioning mechanism to ensure the stability of the stone. When the stone needs to be replaced individually, simply control the locking and limiting mechanism and the swing positioning mechanism to separate. During the separation process, the support plates 16 will retract, and then the stone can be taken out to complete the replacement.

[0026] Please see Figures 1-8 , Figure 10The sway positioning mechanism includes a second sliding groove 1001 formed within the support bracket 10, a movable plate 13 movably disposed within the support bracket 10, and a guide block 1301 fixed on the movable plate 13 that slides and engages with the second sliding groove 1001; it also includes an elastic component and a follower component disposed within the support bracket 10 and connected to the movable plate 13, the elastic component including a guide post 11 fixed within the support bracket 10 and inserted into the movable plate 13, a spring 12 sleeved on the guide post 11, and the two ends of the spring 12 respectively connected to the support bracket 10. The inner wall of the support bracket 10 abuts against the movable plate 13. The follower component includes symmetrically arranged protruding columns 14 fixed to the side wall of the movable plate 13. The support bracket 10 is hinged with a symmetrically arranged first hinge rod 15 and a second hinge rod 17. The first hinge rod 15 and the second hinge rod 17 are respectively hinged to the support plate 16. The first hinge rod 15 has a slot 1501 that slides and engages with the protruding column 14. The end of the movable plate 13 is inclined, and a through-hole limiting groove 1302 is formed on the inclined surface of the movable plate 13.

[0027] In detail, when dry-hanging stone, corresponding grooves need to be opened on the upper and lower sides of the stone. The stone can be fixed by limiting the grooves. Taking the fixing of the lower groove as an example, the first hinge rod 15 and the second hinge rod 17 are combined to form an equilateral quadrilateral structure. According to the quadrilateral law, under the action of the first hinge rod 15 and the second hinge rod 17, the support plate 16 always remains vertical and parallel to the movable plate 13. In the initial state, the support hanger 10 is not yet connected to the receiving plate 5, and the movable plate 13 is located at the end of its stroke away from the support hanger 10, so that the protrusion 14 is located at the end of its stroke on the side of the slot 1501. The column 14 will control the angle between the first hinge rod 15 and the support hanger 10 to be minimized through the slot 1501, thereby cooperating with the second hinge rod 17 to control the distance between the support plate 16 and the support hanger 10 to be minimized. Since the distance between the movable plate 13 and the inner wall of the support hanger 10 is the largest, and the extension of the spring 12 in its natural state is greater than the maximum distance between the movable plate 13 and the inner wall of the support hanger 10, the spring 12 is in a pre-compressed state and always provides the movable plate 13 with a thrust in the direction away from the support hanger 10. When dry hanging of stone is required, the support hanger 10 can be slidably connected to the corresponding first sliding groove 502. During the installation process, since the movable plate 13 extends out of the support hanger... In addition to component 10, the movable plate 13 can be manually controlled to retract into the support bracket 10 to ensure that the support bracket 10 can be smoothly fitted into the first sliding groove 502. When the support bracket 10 is inserted to the end of its stroke in the first sliding groove 502, the movable plate 13 moves to the position of engaging with the through groove 501. At this time, the spring 12 is released elastically and pushes the movable plate 13 to move away from the support bracket 10, so that the movable plate 13 enters the receiving plate 5 through the through groove 501. When the movable plate 13 reaches its maximum extension, the support plate 16 is in a retracted state, and the movable plate 13 no longer moves. At this time, the stone can be transported onto the receiving plate 5, and the groove can be fitted onto the support bracket 10. Since the support plate 1 When the 6 is in a retracted state, the support plate 16 will not interfere with the trough when the groove and the support bracket 10 are inserted into each other. After the stone is placed, the locking and limiting mechanism cooperates with the inclined surface of the movable plate 13. Since the vertical surface of the movable plate 13 is in contact with the side wall of the through groove 501, the movable plate 13 can only move towards the support bracket 10 and compress the spring 12. At the same time, the movable plate 13 will also drive the protrusion 14 to move. Under the action of the protrusion 14 and the slot 1501, the first hinge rod 15 will swing around the hinge point, thereby driving the second hinge rod 17 to swing synchronously through the support plate 16. In this way, the two support plates 16 will move in a direction away from each other.Since the dimensions of the grooves cut into the sidewalls of the stone are processed according to installation specifications, the dimensions of the grooves are fixed. When the support plates 16 move to the end of their travel in the opposite direction, the distance between the sides of the two support plates 16 on the opposite side is exactly the same as the width of the groove. Therefore, the support plates 16 will fit against the sidewalls of the groove. Under the action of the support plates 16, the groove performs a center positioning action on the stone, causing the outer wall of the stone facing the baffle 4 to fit against the baffle 4. Simultaneously, in conjunction with the support plates 16 supporting the groove, the stone can be supported and fixed through the groove.

[0028] Preferably, before stone installation, since the two support plates 16 are in a retracted state, the combined size of the support plates 16 and the support brackets 10 is smaller than that of the stone groove. Therefore, during stone installation, it is not necessary to precisely align the support brackets 10 and the groove; the groove only needs to be fitted onto the support brackets 10 and the support plates 16. This improves the error tolerance during installation and eliminates problems such as edge cracking and scratching of the groove caused by misalignment. At the same time, during subsequent installation, the support plates 16 can move from the retracted state to the unfolded state, allowing the support plates 16 to fit evenly against the two side walls of the groove, thus ensuring uniform stress on the stone. In this way, the slight eccentricity between the brackets and the groove during traditional installation can be avoided, which causes the load to be not symmetrically borne by the groove when the brackets are supported, but rather the brackets and the groove create line support, leading to stress concentration.

[0029] Meanwhile, the stone, after being positioned by the center, can move smoothly to the position where it fits against the baffle 4. Since the stone is installed, its force direction is towards the wall where the vertical keel 1 is installed, that is, towards the baffle 4. Therefore, with the double cooperation of the baffle 4 and the support plate 16, the support force on the stone can be further increased, so as to avoid the problem that when the stone is under force, the load generated is completely applied to the support plate 16 and the groove, causing the groove to break due to the force.

[0030] Please see Figure 5 , Figure 6 , Figure 8 , Figure 9 The locking and limiting mechanism includes a screw 6 threadedly connected to the receiving plate 5, and a push plate 7 rotatably mounted on the end of the screw 6 and slidably connected to the receiving plate 5. The locking and limiting mechanism also includes a limiting post 8 fixed on the push plate 7 and symmetrically arranged. The limiting post 8 is slidably engaged with the limiting groove 1302. A limiting plate 9 is fixed on the limiting post 8 and abuts against the inclined surface of the movable plate 13. The end of the screw 6 away from the push plate 7 has an internal hexagonal groove for assisting the rotation of the screw 6.

[0031] Furthermore, the end of the receiving plate 5 is threaded, allowing the screw 6 to translate horizontally when it rotates. The limiting plates 9 are mirror-symmetrically arranged, with one limiting plate 9 engaging with the inclined surface of the movable plate 13 for bottom support, and the other limiting plate 9 engaging with the inclined surface of the movable plate 13 for top support. Taking the limiting plate 9 engaging with the movable plate 13 for bottom support as an example, in the initial state, under the action of the screw 6, the pushing plate 7 controls the limiting post 8 and the limiting plate 9 to be at the end of their stroke away from the baffle 4, ensuring that the limiting post 8 and the limiting plate 9 do not come into contact with the movable plate 13. Interference occurs when the support bracket 10 is inserted into the first groove 502. After the support bracket 10 is inserted, the movable plate 13 is controlled to enter the receiving plate 5 through the through groove 501 under the action of the spring 12. The limiting groove 1302 on the movable plate 13 and the limiting post 8 are on the same axis. Subsequently, the screw 6 with the internal hexagonal groove can be rotated by the hexagonal wrench. Under the action of the thread, the screw 6 will gradually enter the receiving plate 5. The screw 6 will also drive the push plate 7 to move. Since the push plate 7 is slidably connected to the receiving plate 5, the push plate 7 will not rotate with the screw 6. The push plate 7 will also drive the limiting post 8 to move. The positioning post 8 and the limiting plate 9 enter, so that the limiting post 8 first inserts into the limiting groove 1302. Since the movable plate 13 is located at the end of its stroke away from the support bracket 10, the distance between the limiting post 8 and the side of the limiting groove 1302 away from the support bracket 10 is the largest. When the limiting plate 9 moves to the position of abutting against the inclined surface of the movable plate 13, it pushes the movable plate 13 to move, so that the movable plate 13 first abuts against the side wall of the through groove 501, and then pushes the movable plate 13 towards the support bracket 10. The limiting post 8 will slide relative to the movable plate 13 along the limiting groove 1302. The movable plate 13 will be controlled by the protrusion 14 and the slot 1501. The first hinge rod 15 is rotated to guide the two support plates 16 to swing away from each other. When the two support plates 16 open to their maximum size, the limiting post 8 is located at the end of the stroke of the limiting groove 1302 on the side away from the support bracket 10. Under the action of the limiting post 8 and the limiting groove 1302, the movable plate 13 is prevented from continuing to move into the support bracket 10. Under the action of the limiting plate 9 and the inclined surface of the movable plate 13, the movable plate 13 is also prevented from moving away from the support bracket 10. In this way, the position of the two support plates 16 after reaching the maximum distance can be locked through the double limiting method.

[0032] If the stone needs to be removed and replaced, simply reverse the screw 6 to separate the limiting post 8 and the limiting plate 9 from the limiting groove 1302 and the movable plate 13, respectively. The spring 12 will be released elastically, so that the movable plate 13 is once again at the end of its stroke away from the support bracket 10. At this time, the stone can be controlled to detach from the receiving plate 5 and move the support bracket 10 through the groove. The support bracket 10 will then move the movable plate 13. Under the action of the inclined surface of the movable plate 13, the movable plate 13 can smoothly detach from the through groove 501. In this way, the dry-hanging stone can be quickly disassembled and replaced without the need for tools to violently destroy it.

[0033] A method for using a support and limiting device for dry-hanging stone wall construction includes the following steps: Step 1: Install the support bracket 10 into the first slide groove 502; Step 2: Transfer the stone material with the groove that matches the support bracket 10 onto the receiving plate 5, and insert the support bracket 10 into the groove; Step 3: Under the action of the locking and limiting mechanism, the two support plates 16 are controlled to swing by the swing positioning mechanism; Step 4: When the support plate 16 is in contact with the inner wall of the stone groove, the stone is supported and positioned. At the same time, under the action of the locking and limiting mechanism, the position of the support plate 16 is locked by the swing positioning mechanism.
