Description

Technical Field

[0001] This invention relates to the field of building fixtures technology, and in particular to an adjustable base and a dry-hanging leveling component for wall materials. Background Technology

[0002] In architectural decoration projects, the installation of large-format ceramic tiles and sintered stone slabs on walls mainly employs two techniques: wet-laying and dry-hanging. Wet-laying relies on cement mortar bonding, which has drawbacks such as a long construction period, significant susceptibility to environmental temperature and humidity fluctuations, and a high risk of later hollowing and detachment, making it difficult to meet the demands of high-quality decoration. In contrast, the dry-hanging technique uses metal hangers to directly fix the decorative panels to the building's main structure, eliminating the need for on-site grouting. It offers advantages such as secure installation, fast construction speed, and ease of maintenance, making it particularly suitable for large-format, high-quality sintered stone slabs and exterior wall cladding projects. It is currently the mainstream high-end wall construction method.

[0003] Existing dry-hanging technologies mainly include slotted dry-hanging and back-bolted dry-hanging. Slotted dry-hanging requires manual slotting at the top and bottom of the tiles to install fasteners. This process is not only time-consuming and prone to edge chipping or hidden cracks, but the dust generated during slotting also has adverse effects on the health of construction workers and the environment. Back-bolted dry-hanging requires precise drilling of the back of the tiles in the factory and the insertion of back bolts. This process demands highly skilled equipment and operators. Drilling weakens the strength of the tiles, leading to stress concentration and potential cracking. Furthermore, it requires specialized back bolt accessories, significantly increasing material and construction costs. To address these pain points, improved connectors such as CN223482179U have emerged in the industry. These connectors improve structural strength by incorporating through holes and reinforcing ribs on the connecting plate. However, this solution is still limited by the rigid constraints of the circular hole positioning, failing to effectively absorb pre-embedded errors from civil construction and lacking effective three-dimensional adjustment capabilities.

[0004] To further simplify the installation process, keelless hanging structures have emerged. For example, CN217630999U discloses a keelless dry-hanging structure that attempts to eliminate the complex keel frame and save costs by setting mounting plates with internal threads at the corners of the panels. However, such existing technologies generally suffer from limited functionality: their mounting plate structure design can only adapt to a single dry-hanging connection method and cannot be compatible with adhesive processes, resulting in limited applicability when dealing with ultra-thin panels, thin wall materials, or sintered stone. At the same time, traditional square or rectangular adjustment plates are easily interfered with by the corners when finely adjusting the angle around the center, limiting the freedom of circumferential adjustment, and it is difficult to ensure multi-point matrix leveling (uniformity) while also meeting the mechanical interlocking requirements of the structural adhesive after curing.

[0005] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0006] To address the technical deficiencies mentioned in the background section, the present invention aims to provide a universal leveling base and component that combines the dual functions of dry hanging and adhesive bonding of wall materials, and possesses high tolerance for error adjustment. This solution utilizes a circular base body with four radially and circumferentially staggered waist-shaped anchoring holes to achieve rotational fine-tuning and radial displacement compensation based on the central hole, effectively solving the installation difficulties caused by pre-embedded point deviations. Simultaneously, the raised blind holes on the back and the friction texture on the front allow the base to both cooperate with the hanging rail for rapid leveling and hanging of wall panels, and also serve as an independent adhesive fulcrum. The adhesive, penetrating the waist holes and blind holes, forms an H-shaped and T-shaped mechanical interlocking structure after curing, thus achieving compatible installation of two different materials—rock slabs and wall panels—on a single component, significantly improving construction efficiency and system reliability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable base includes a base body and an anchor for anchoring the base body to a wall. The base body has a central reference hole in the middle and four waist-shaped anchor holes that are evenly distributed around the central reference hole. The base body also has at least one protrusion facing the back, and a blind hole is formed on the back of the protrusion.

[0008] Specifically, the anchor includes: Expansion sleeve, pre-embedded in the wall; The expansion screw passes through the central reference hole of the base body and is connected to the expansion sleeve.

[0009] Specifically, the expansion screw is provided with a threaded adjustment section; The anchor also includes at least one adjusting shim, which is disposed between the expansion sleeve and the adjusting base and is threadedly connected to the threaded adjusting section.

[0010] Specifically, two of the waist-shaped anchor holes extend laterally, and the other two waist-shaped anchor holes extend longitudinally. The waist-shaped anchor holes extending laterally and the waist-shaped anchor holes extending longitudinally are alternately distributed around the central reference hole in a circumferential direction.

[0011] Specifically, there are four protrusions, which are evenly distributed around the central reference hole in a circumferential direction.

[0012] Specifically, both the protrusion and the front of the blind hole are formed into a frustum shape by stamping.

[0013] Specifically, the base body is a circular sheet structure.

[0014] A dry-hanging leveling component for wall materials includes: The adjustment base; A hanging rail is fixed to the front of the base body, and the hanging rail is provided with a hanging groove; The anchor secures the base body and the rail anchor together to the wall.

[0015] Specifically, the length of the hanging rail does not exceed three times the diameter of the base body.

[0016] Specifically, the upper part of the hanging rail away from the base body is provided with a hanging plate located on one side of the hanging groove, and the lower part is provided with a stop bar located on one side of the hanging groove. An elastic pad is installed inside the stop bar, and one end of the elastic pad extends out of the front of the stop bar and forms an arched contact surface.

[0017] Beneficial effects: This application breaks through the limitations of traditional square adjustment plates by using a circular base body with four waist-shaped anchor holes arranged radially and circumferentially. This allows the component to achieve radial translation to compensate for pre-embedded deviations during installation, and to perform small-angle rotation correction with the central reference hole as the center, significantly improving the construction error tolerance and leveling freedom. At the same time, the protrusion and blind hole structure on the back of the base body reduces the flatness requirements of installation while reserving space for adhesive. After the adhesive is injected, it forms an inverted T-shaped adhesive nail, achieving mechanical interlocking and greatly enhancing the pull-out and shear resistance of the adhesive connection. In addition, the threaded design of the dual adjustment shims allows for independent control of the flatness and depth of the base body. Combined with the use of segmented short hanging rails, it effectively avoids the deflection deformation of long rails, achieving high-precision multi-point matrix leveling, compatible with both rock slab adhesive and wall panel dry hanging construction scenarios.

Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0021] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] 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 with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0023] In this application, unless otherwise expressly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components, unless otherwise expressly limited.

[0024] Example 1 like Figure 1 and Figure 2 As shown, this embodiment discloses a wall material dry-hanging leveling component, including an adjusting base and a hanging rail 40. The hanging rail 40 is fixed to the front of the base body 10, and the hanging rail 40 is provided with a hanging groove 41 for supporting the back hanger 60 of the wall material 50; the anchor 30 passes through the hanging rail 40 and the base body 10 in sequence, anchoring the two together to the wall 20. By utilizing the circular outline of the base body 10 and the cooperation of the waist-shaped anchor hole 12, the limitation of interference at the corners of the traditional square adjusting plate is broken, so that the hanging rail 40 can not only achieve radial translation during installation, but also rotate and correct itself at a small angle with the central reference hole 11 as the center, thereby greatly absorbing the cumulative error brought about by civil construction, ensuring the straightness and levelness of the hanging rail 40 over long spans, and providing a high-precision reference surface for the rapid hanging of the wall material 50.

[0025] It should be noted that, in addition to the circular structure, the base body 10 can also be selected as a square, hexagonal, or other polygonal or even irregularly shaped sheet structure according to the actual working conditions. As long as it has a central reference hole and waist-shaped anchoring holes distributed around it, it can achieve basic adjustment and anchoring functions. However, the circular structure is the optimal implementation scheme of this application. Its advantages are: the circular outline has natural rotational symmetry. In the construction of concealed works, even if one or more base bodies 10 are deflected at an angle due to on-site errors, they still maintain a neat and uniform appearance and will not produce obvious directional confusion. In contrast, if a rectangular or polygonal structure with sharp edges is used, once an angle deviation occurs during installation, it is very easy to be identified by the naked eye as an irregular arrangement, which seriously affects the overall visual quality of the decoration project. Therefore, the circular base body has an irreplaceable advantage in balancing the freedom of adjustment and visual aesthetics.

[0026] like Figure 3 and Figure 4 As shown, the adjustment base includes a base body 10 and anchors 30 for anchoring the base body 10 to the wall 20. A central reference hole 11 is provided in the middle of the base body 10. This hole serves not only as a passage for the anchors 30 but also as the positioning reference point for the entire adjustment base. The base body 10 also has four waist-shaped anchor holes 12, evenly distributed around the central reference hole 11. The back of the base body 10 has at least one protrusion 13 facing the wall 20, with a blind hole 14 formed on the back of the protrusion 13. This circular, sheet-like structure, combined with the protruding back design, ensures that when the base body 10 contacts the wall, only the edge of the protrusion 13 makes point contact with the wall, rather than the entire plane. This not only reduces the precision requirements for the machined surface but, more importantly, provides space for adhesive between the base body 10 and the wall 20. Furthermore, the blind hole 14 on the back forms an inverted structure after structural adhesive is injected, greatly enhancing the pull-out and shear resistance of the adhesive bond.

[0027] like Figures 5 to 9 As shown, in the actual construction and installation process, regarding Figure 8The example shown involves installing three horizontally arranged wall panels 50. Each wall panel 50 has seven horizontally positioned brackets 60 on its back and four vertically positioned brackets 60. Adjacent wall panels 50 share the central bracket 60. The worker first measures and lays out the lines on the wall 20. Using a horizontal marking method, four horizontal and seven vertical reference lines are drawn on the wall. The intersection of these reference lines is the predetermined location of the wall hole 21. Next, the worker attaches the base body 10 to the wall 20, roughly aligning the central reference hole 11 with the intersection point. Then, using a pen or awl, the worker traces the trajectory of the four positioning holes 22 on the wall 20 through the four waist-shaped anchor holes 12. Because the waist-shaped anchor holes 12 have a certain adjustment range, even if the wall hole 21 is slightly off, it can be compensated for in subsequent steps. After tracing, the base body 10 is removed, and the actual wall holes 21 are drilled according to the trajectory of the positioning holes 22. The depth of the wall hole 21 needs to be slightly greater than the length of the expansion sleeve 31 to ensure that after the expansion sleeve 31 is fully driven in, there is a certain amount of room for movement between its tail and the bottom of the hole, so as to avoid the wall 20 cracking or the base body 10 failing to fit due to rigid jamming.

[0028] like Figure 1 and Figure 2 As shown, the anchor 30 includes an expansion sleeve 31 and an expansion screw 32. The expansion sleeve 31 is pre-embedded and hammered into the wall hole 21 of the wall 20; the expansion screw 32 passes through the mounting hole on the rail 40 and the center reference hole 11 of the base body 10 in sequence, and is then threadedly locked to the expansion sleeve 31. This connection method connects the rail 40, the adjusting base, and the wall 20 into a whole, achieving a rigid connection using the pull-out force of the expansion screw 32. At the same time, since the diameter of the mounting hole on the rail 40 is slightly larger than the diameter of the expansion screw 32 (preferably 2~4mm), the rail 40 can be vertically fine-tuned using this gap before being fully locked, further eliminating processing and installation errors.

[0029] like Figure 2As shown, the expansion bolt 32 has a threaded adjustment section 321; the anchor 30 also includes two adjusting shims 33, both of which are threadedly connected to the threaded adjustment section 321 and are spaced apart between the expansion sleeve 31 and the base body 10. Both adjusting shims 33 use hexagonal nuts for easy wrench operation. The adjusting shim 33 close to the end face of the expansion sleeve 31 is mainly used to adjust the verticality and flatness of the base body 10 relative to the wall 20; while the adjusting shim 33 located at the end of the threaded adjustment section 321 and close to the back of the base body 10 is used to control the distance between the base body 10 and the wall 20. By rotating these two adjusting shims 33, the construction personnel can precisely control the entry and exit position of the base body 10, so that the multiple base bodies 10 arranged in a matrix on the wall 20 form a leveling reference plane with consistent height, thereby ensuring that the subsequently installed hanging rail 40 is in the same plane.

[0030] like Figure 6 and Figure 7 As shown, two waist-shaped anchor holes 12 extend laterally, and the other two waist-shaped anchor holes 12 extend longitudinally. The waist-shaped anchor holes 12 extending laterally and longitudinally are alternately distributed around the central reference hole 11. This staggered arrangement gives the base body 10 a high degree of adjustment freedom: the lateral waist-shaped anchor holes 12 are mainly responsible for absorbing horizontal pre-embedding deviations, while the longitudinal waist-shaped anchor holes 12 are mainly responsible for absorbing vertical pre-embedding deviations. When encountering hollow areas or obstacles inside the wall 20 that prevent nailing at a predetermined location, workers do not need to re-lay out the lines. They only need to slightly rotate the base body 10, using the long groove stroke of the waist-shaped anchor holes 12 to avoid the obstacle area and reselect a suitable anchor point, greatly improving the construction error tolerance and on-site adaptability.

[0031] like Figure 8 As shown, the length of the hanging rail 40 does not exceed three times the diameter of the base body 10, preferably 150mm to 200mm. Compared with the traditional continuous aluminum alloy rail, this segmented short hanging rail 40 design not only significantly reduces the material cost of aluminum profiles, but more importantly, it changes the force transmission path. The short hanging rail 40 directly overlaps two adjacent adjustment bases, avoiding the deflection deformation caused by the weight of the long rail through two-point support. At the same time, each short hanging rail 40 can be independently leveled through the adjustment bases at both ends, changing the wall-mounting system from traditional line control to point control. The leveling operation is more precise and convenient, and the straightness of the entire rail will not be affected by the accumulation of errors at a certain point.

[0032] like Figure 1 and Figure 9As shown, the upper part of the hanging rail 40, away from the base body 10, is provided with a hanging plate 42 located on one side of the hanging groove 41, and the lower part is provided with a stop strip 43 located on one side of the hanging groove 41. An elastic pad 44 is installed inside the stop strip 43, and one end of the elastic pad 44 extends out of the front of the stop strip 43 and forms an arched contact surface. When the hanger 60 on the back of the wall material 50 is inserted into the hanging groove 41 and overlaps with the hanging plate 42, the bottom of the hanger 60 will press against the arched contact surface of the elastic pad 44, causing it to undergo elastic deformation. This elastic pre-tightening force not only eliminates the assembly gap between the hanger 60 and the hanging groove 41, effectively preventing the wall material 50 from shaking or making abnormal noise when subjected to slight vibration, but also absorbs the slight expansion and contraction deformation of the wall 20 caused by temperature changes, avoiding the wall material 50 from being crushed and damaged due to thermal expansion and contraction.

[0033] Example 2 Please refer to Figure 10 In this embodiment, the adjusting shim 33 facing the base body 10 uses a standard hexagonal nut for easy adjustment using tools; while the other adjusting shim 33 close to the wall 20 uses a rectangular shim with threaded holes. This rectangular shim has a larger contact area, providing more stable support on the rough surface of the wall 20 and preventing the base body 10 from tilting or wobbling due to localized point contact. Simultaneously, the edge of the rectangular shim can better fit against the plaster layer or concrete surface of the wall 20, providing a certain degree of sealing and anti-loosening effect, further enhancing the installation stability of the adjusting base in complex wall surface environments.

[0034] Example 3 Please refer to Figures 11-13 This embodiment demonstrates the application scenario of the adjustable base without the hanging rail 40, primarily suitable for direct adhesive dry hanging of large-format slabs or tiles. In this scenario, the base body 10 is first firmly anchored to the wall 20 using anchors 30. Then, adhesive 70 is applied to the back of the wall material 50, and the adhesive-coated wall material 50 is pressed onto the front of the base body 10. Before curing, the adhesive 70 fully flows and fills the waist-shaped anchor holes 12. After curing, it forms an H-shaped structural adhesive column, which provides extremely strong tensile strength in the direction perpendicular to the wall. Simultaneously, the adhesive 70 flowing into the blind hole 14 on the back of the protrusion 13 cures to form a T-shaped adhesive nail. This mechanical interlocking structure further enhances the bonding strength between the base body 10 and the adhesive 70, enabling the entire system to rely on chemical bonding while also possessing physical anchoring force, making it particularly suitable for the installation needs of ultra-heavy and ultra-large decorative materials.

[0035] To ensure that the base body 10 does not deform or tear under high tensile force, there are four protrusions 13, which are evenly distributed around the central reference hole 11. This symmetrical layout allows the anchoring force and the weight of the plate to be evenly distributed to the base body 10 through four support points, avoiding stress concentration. In addition, the front sides of the protrusions 13 and the blind holes 14 are integrally formed into a frustum shape by stamping. This shape not only increases the structural strength of the base body 10 itself, similar to the function of a reinforcing rib, but also provides a larger climbing area and shear force bearing surface for the adhesive 70 on the frustum-shaped blind hole 14 sidewalls, further improving the shear resistance of the T-shaped adhesive nail.

[0036] To further enhance the friction between the base body 10 and the adhesive 70, several stamped anti-slip textures (not shown) can be created on the front side of the base body 10 through grinding, stamping, or other methods. These anti-slip textures disrupt the smoothness of the steel surface, increasing the surface roughness, allowing the adhesive 70 to grip the base body 10 more tightly. This prevents the wall material 50 from slipping along the surface of the base body 10 in extreme cases, ensuring the long-term safety and stability of the entire dry-hanging system.

[0037] Example 4 Please refer to Figure 14 This embodiment provides a dry-hanging and leveling component for wall materials, with the hanging rail 40 having an I-shaped structure. The I-shaped hanging rail 40 has two parallel flanges, connected by a web. The right flange is fixed to the front of the base body 10, while the left flange supports the back hanger 60 of the wall material 50. Compared to conventional single-groove structures, the I-shaped cross-section significantly improves bending and torsional stiffness, effectively resisting lateral overturning moments generated when hanging heavy rock slabs or wall panels, preventing the hanging rail 40 from deforming under pressure. It is particularly suitable for installation scenarios with large spans or high load-bearing requirements.

[0038] Example 5 Please refer to Figure 15 This embodiment provides a dry-hanging and leveling component for wall materials, with the hanging rail 40 having an inverted "h" shaped structure. The lower part of the cross-sectional profile of the hanging rail 40 is closed, while the upper part is open, and the back plane is tightly fitted to the base body 10. This design reduces the weight of the profile while maximizing the compressive and torsional resistance of the hanging rail 40. The flat contact surface on the back increases the welding or bolting area with the base body 10, resulting in a more stable connection. The open hanging groove 41 at the top facilitates the quick insertion and removal of the back hanger 60 of the wall material 50, balancing structural strength and ease of construction.

[0039] Example 6 Please refer to Figure 16This embodiment provides a dry-hanging and leveling component for wall materials, with the hanging rail 40 having an "h"-shaped structure. The hanging rail 40 has a left flange, a right flange, and a web connecting the two. The left flange connects to the base body 10, and the upper surface of the right flange forms a bearing surface to support the back hanger 60 of the wall material 50. Compared to an I-shaped structure, the "h"-shaped hanging rail 40 omits the upper hanging groove sidewall, making the installation space of the hanger 60 more open, facilitating visual observation and manual adjustment. Simultaneously, the right flange provides a large support area, dispersing the pressure of the hanger 60 on the hanging rail 40, reducing the profile wall thickness requirement, and further saving on aluminum profile raw material costs while meeting load-bearing capacity requirements.

[0040] In summary, those skilled in the art should understand that the core concept of this application lies in utilizing the circular contour of the adjusting base and the multi-directional waist-shaped anchoring holes to achieve highly tolerant adjustment of pre-embedded deviations. Based on this, a wall mounting reference is constructed through the rigid connection between the base body 10 and the hanging rail 40. Therefore, regardless of whether the hanging rail 40 is I-shaped, H-shaped, inverted H-shaped, or has other irregular cross-sectional shapes, as long as it uses the aforementioned adjusting base as a support point and serves to support the wall material 50, connect the adjusting base, fasten the back hanger 60, and assist in anchoring to the wall 20, it utilizes the core adjustment mechanism and structural features of this application and falls within the scope of protection defined by the claims of this application.

[0041] The embodiments described above are merely illustrative of one or more specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all such modifications and improvements fall within the protection scope of the present invention.
