Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a dry-hanging stone system and its installation method. Background Technology

[0002] Dry-hanging stone cladding is a construction technique for building exterior walls. Currently, the main methods for fixing stone include pin-type, slotted-type, and back-bolted type. Back-bolted dry-hanging involves drilling holes in the back of the stone and using back bolts to connect it to the keel structure. This provides a clear anchoring force system, and the stone panel system is not affected by the anchor bolt's load-bearing capacity. It also reduces the support spacing of the stone panels and offers good seismic resistance. Compared to pin-type and slotted-type methods, it is more widely used.

[0003] However, during construction, when using the back-bolted dry-hanging method to dry-hang curved stone, in order to ensure the installation stability of the curved stone, it is usually necessary to ensure that the back bolt assembly on the hanger and the radial direction of the curved stone are roughly coincident. This requires the installation of a relatively complex keel frame, which is troublesome. Summary of the Invention

[0040] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0041] It should be noted that when a component is referred to as being "mounted to," "fixed to," or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] like Figures 1 to 7As shown, this application provides a dry-hanging stone cladding system, including a main load-bearing component 1 and two secondary load-bearing components 2. The main load-bearing component 1 includes a main load-bearing plate 11. Both secondary load-bearing components 2 are installed on the main load-bearing component 1. Each secondary load-bearing component 2 includes a secondary load-bearing plate 21, a secondary bolt assembly 22, and a hanger 23. The secondary load-bearing plate 21 is installed on the main load-bearing plate 11 and is rotatable relative to the main load-bearing plate 11. The secondary bolt assembly 22 passes through the main load-bearing plate 11 and the secondary load-bearing plate 21 and is configured to fix the secondary load-bearing plate 21 to the main load-bearing plate 11. The hanger 23 is hung on the secondary load-bearing plate 21.

[0044] This application provides a dry-hanging stone system. When dry-hanging curved stone, the angle between two secondary support plates 21 can be adjusted according to the curvature and diameter direction of the curved stone, thereby adjusting the angle between two hangers 23. This ensures that the radial directions of the hangers 23 and the curved stone are approximately aligned. Compared to existing technologies, this eliminates the need for a complex keel frame 3 (excluding vertical keels 31 and horizontal keels 32), significantly reducing installation difficulty. Furthermore, the main support plate 11 has two hangers 23, compared to the existing technology which only has one hanger 23. This provides more contact points between the hangers 23 and the stone, thus improving the structural stability between the hangers 23 and the stone, making it less likely for the stone to detach from the hangers 23.

[0045] In one embodiment of this application, please refer to Figures 1 to 7 The main support plate 11 includes a main plate 111 and two first main tooth surfaces 112. The main plate 111 is mounted on the keel frame 3. The two first main tooth surfaces 112 are formed on both sides of the main plate 111 and are correspondingly arranged with the two secondary support plates 21. The secondary support plate 21 includes a horizontal plate 211 and secondary tooth surfaces 212. The secondary tooth surfaces 212 are formed on the side of the horizontal plate 211 facing the main plate 111 and mesh with the first main tooth surfaces 112.

[0046] This configuration, after the secondary support plate 21 rotates relative to the main support plate 11, prevents it from rotating relative to the main support plate 11 through the meshing of the first main tooth surface 112 and the secondary tooth surface 212. This helps improve the structural stability between the secondary support plate 21 and the main support plate 11, and also improves the installation stability of the stone. The secondary bolt assembly 22 prevents the secondary support plate 21 from detaching from the main support plate 11 and stably locks it to the main support plate 11, further enhancing the structural stability between them.

[0047] Optionally, both the first main tooth surface 112 and the secondary tooth surface 212 are composed of multiple straight teeth, which together form a circular tooth surface.

[0048] In one embodiment of this application, please refer to the following: Figures 1 to 7The main load-bearing component 1 also includes an angle steel 12 and a main bolt assembly 13. The angle steel 12 is installed on the keel frame 3, and the main bolt assembly 13 passes through the main load-bearing plate 11 and the angle steel 12, and is configured to fix the angle steel 12 to the main load-bearing plate 11. The main load-bearing plate 11 also includes a second main tooth surface 113 and a waist-shaped hole 114. The second main tooth surface 113 is formed on the side of the main plate 111 facing the angle steel 12, and the waist-shaped hole 114 is opened in the main plate 111. The angle steel 12 includes a first mounting plate 121, an adjusting plate 122, an adjusting tooth surface 123, and a through hole 124. The first mounting plate 121 is installed on the keel frame 3, the adjusting plate 122 is connected to the first mounting plate 121 and is bent relative to the first mounting plate 121, the adjusting tooth surface 123 is formed on the side of the adjusting plate 122 facing the main plate 111 and engages with the second main tooth surface 113, and the through hole 124 is opened in the adjusting plate 122.

[0049] This configuration allows for adjustment of the distance between the two hangers 23 and the keel frame 3 during construction. The distance between the curved stone and the keel frame 3 can be adjusted by changing the position of the main bearing plate 11 on the adjusting plate 122, thus enabling the dry-hanging of stones of different sizes. Fine-tuning is also possible based on the installation scenario, improving applicability and ease of installation. The meshing action of the second main tooth surface 113 and the adjusting tooth surface 123 secures the main bearing plate 11 after adjustment, preventing it from moving relative to the adjusting plate 122 and improving the structural stability between them, thereby enhancing the installation stability of the stone. The main bolt assembly 13 prevents the main bearing plate 11 from detaching from the adjusting plate 122 and securely locks it in place, further improving the structural stability between the two. The through hole 124 allows the main bolt assembly 13 to be fixed to the adjusting plate 122, preventing the main bolt assembly 13 from moving with the main support plate 11 during adjustment. The oblong hole 114 allows the main bolt assembly 13 to be positioned away from the main support plate 11 during adjustment, preventing interference between the main bolt assembly 13 and the main support plate 11 and ensuring the main support plate 11 can move. Furthermore, depending on the installation scenario, when the angle steel 12 is not needed, it can be removed from the main support plate 11, and the main support plate 11 can be installed onto the keel frame 3 using the main bolt assembly 13, making installation convenient.

[0050] In one embodiment of this application, see [reference] Figures 1 to 7The secondary support plate 21 includes a horizontal plate 211 and a vertical plate 213. The vertical plate 213 is connected to the horizontal plate 211 and is bent relative to the horizontal plate 211. The hanger 23 includes a U-shaped plate 231, a first mounting groove 232, a second mounting plate 233, a second mounting groove 234, and a back bolt assembly 235. The first mounting groove 232 is formed in the U-shaped plate 231 and is configured to hang the U-shaped plate 231 on the secondary support plate 21. The second mounting plate 233 is connected to the U-shaped plate 231. The second mounting groove 234 is formed in the second mounting plate 233. The back bolt assembly 235 passes through the second mounting plate 233.

[0051] With this configuration, the U-shaped plate 231 can be stably hung on the vertical plate 213 by the first mounting groove 232. The back bolt assembly 235 can stably fix the stone to the second mounting plate 233. The second mounting groove 234 can avoid misalignment of the back bolt assembly 235, thus preventing interference between the back bolt assembly 235 and the vertical plate 213, which would prevent the back bolt assembly 235 from being installed on the second mounting plate 233. When adjusting the angle between the two hangers 23, this dry-hanging stone system can be used for dry-hanging flat stone when the two vertical plates 213 are in the same plane, making it widely applicable.

[0052] In one embodiment of this application, please refer to Figures 1 to 7 The hanging part 23 also includes an adjusting bolt 236, which is screwed to the U-shaped plate 231 and abuts against the vertical plate 213.

[0053] With this configuration, the relative position between the U-shaped plate 231 and the vertical plate 213 can be adjusted by the adjusting bolt 236, thereby adjusting the position of the back bolt assembly 235. This ensures that the back bolt assembly 235 is always aligned with the stone opening, which helps to improve the applicability and ease of installation.

[0054] In one embodiment of this application, please refer to the following: Figures 1 to 7 The hanging part 23 also includes two first adhesive strips 237, which are respectively snapped onto both sides of the U-shaped plate 231 and abut against the U-shaped plate 231 and the vertical plate 213.

[0055] This design, with the help of the two first adhesive strips 237, prevents direct contact between the U-shaped plate 231 and the vertical plate 213. When the stone is impacted, a buffer zone is formed between the U-shaped plate 231 and the vertical plate 213, which effectively protects the U-shaped plate 231 and the vertical plate 213, making it less likely for the stone to fall off the hanger 23.

[0056] In one embodiment of this application, see [reference] Figures 1 to 7The second mounting plate 233 includes a first plate 2331, a second plate 2332, a third plate 2333, and a fourth plate 2334. The first plate 2331 is connected to the U-shaped plate 231. The second plate 2332 is connected to the end of the first plate 2331 away from the U-shaped plate 231. The third plate 2333 is connected to the end of the second plate 2332 away from the first plate 2331. The fourth plate 2334 is connected to the end of the third plate 2333 away from the second plate 2332. The first plate 2331, the second plate 2332, and the third plate 2333 together form a second mounting groove 234. The hanger 23 also includes a second adhesive strip 238, which is snapped onto the fourth plate 2334 and abuts against the vertical plate 213.

[0057] With this configuration, the fourth plate 2334 provides greater structural stability compared to the third plate 2333 directly abutting against the vertical plate 213, making it less prone to deformation. This allows the back bolt assembly 235 to more stably secure the stone, preventing it from shifting. The second adhesive strip 238 prevents direct contact between the fourth plate 2334 and the vertical plate 213. When the stone is impacted, a buffer zone is formed between the fourth plate 2334 and the vertical plate 213, effectively protecting the U-shaped plate 231 and the vertical plate 213, preventing the stone from easily detaching from the hanger 23.

[0058] In one embodiment of this application, please refer to Figures 1 to 7 The keel frame 3 includes multiple vertical keels 31, all of which are installed on a concrete structure; or, the keel frame 3 also includes multiple vertical keels 31 and multiple horizontal keels 32, with the multiple vertical keels 31 installed on a concrete structure and the multiple horizontal keels 32 installed on the multiple vertical keels 31.

[0059] It should be noted that in this embodiment, the keel frame 3 is described as including multiple vertical keels 31 and multiple horizontal keels 32. Of course, in other embodiments, the keel frame 3 may only include multiple vertical keels 31.

[0060] With this configuration, when installing the main load-bearing component 1 and the two secondary load-bearing components 2, they can be installed using multiple vertical keels 31 and multiple horizontal keels 32, or they can be installed using only multiple vertical keels 31 (i.e., the first mounting plate 121 is directly installed on the vertical keel 31). Compared with the existing technology, there is no need to install additional keels or other structures, which greatly simplifies the installation process and makes installation convenient.

[0061] The working principle of the dry-hanging stone system provided in this application is as follows:

[0062] During installation, before installation, the relative positions between the main support plate 11 and the adjusting plate 122 are pre-adjusted according to the distance between the stone and the keel frame 3, and then fixed with the main bolt assembly 13. Subsequently, according to the curvature of the curved stone, the angle between the two horizontal plates 211 is adjusted until the two hangers 23 approximately coincide with the diameter direction of the curved stone, and then fixed with the auxiliary bolt assembly 22. Under the action of the external bolt assembly, the first mounting plate 121 is installed onto the vertical keel 31 or the horizontal keel 32. After installation, the curved stone is dry-hung onto multiple back bolt assemblies 235.

[0063] like Figures 1 to 3 As shown, this application also provides a method for installing a dry-hanging stone system, which includes at least the following steps:

[0064] Step S1: Install the keel frame 3.

[0065] Step S2: Install main carrier component 1.

[0066] Step S3: Adjust the angle between the two secondary load-bearing components 2 according to the shape of the stone.

[0067] Step S4: Install the stone.

[0068] The dry-hanging stone system installation method provided in this application, compared with the existing technology, does not require the installation of a complex keel structure, and can be used for dry-hanging different types of stone, with a wide range of applications and simple installation.

[0069] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
