Description

Technical Field

[0001] This utility model relates to the field of thermal insulation metal plate fixing technology, specifically to a rotary expansion anchoring integrated plate installation structure. Background Technology

[0002] Traditional construction methods for integrated thermal insulation panels involve using screw-in expansion bolts and anchors. The process involves first marking the anchor positions with a chalk line, drilling holes, pre-embedding plastic expansion tubes, installing the integrated panel anchors (ensuring the anchor holes align with the expansion tubes), and finally tightening with self-tapping screws. This method has several problems. First, the construction steps are cumbersome, time-consuming, and labor-intensive, increasing construction costs. Second, if the wall is made of porous aerated concrete blocks, the expansion bolts cannot be firmly embedded, and even if they are, the anchor tension may not meet the standard value, resulting in insecure installation and safety hazards. Furthermore, traditional installation structures are prone to deviations during installation, affecting the overall aesthetics and construction quality. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary expansion anchoring integrated plate installation structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary expansion anchor integrated plate installation structure, comprising an L-shaped installation strip, a rotary expansion screw, and a positioning plate. The positioning plate is integrally formed by a gasket and a positioning cylinder. The outer diameter of the gasket is larger than the cross-sectional diameter of the positioning cylinder, and the inner diameter of the gasket is the same as the inner diameter of the positioning cylinder. The expansion fixing end of the rotary expansion screw passes through the gasket and the positioning cylinder and is placed in the base wall. The rotary nut section of the rotary expansion screw abuts against the gasket. The vertical end surface of the L-shaped installation strip is provided with an installation hole. The diameter of the installation hole is adapted to the cross-sectional diameter of the positioning cylinder, and the length of the positioning cylinder is greater than the vertical end thickness of the L-shaped installation strip. The horizontal end surface of the L-shaped installation strip is provided with a fixing hole.

[0005] In some embodiments, the fixing hole is provided as a waist-shaped hole.

[0006] In some embodiments, the mounting hole is a stepped slot, and the gasket is placed inside the larger end of the stepped slot. In some embodiments, the thickness of the gasket is the same as the height of the larger end of the stepped slot.

[0007] In some embodiments, a pull-out rivet is provided in the fixing hole, and the side of the integrated metal insulation panel is fixedly connected to the horizontal end of the L-shaped mounting strip by the pull-out rivet. In some embodiments, a level is magnetically attached to the L-shaped mounting strip.

[0008] Compared with the prior art, the beneficial effects of this utility model are: through the cooperative design of the positioning plate and the rotary expansion screw, and the matching structure of the mounting hole of the L-shaped mounting strip and the positioning cylinder, fast and accurate installation is achieved, while enhancing the anchoring force.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the traditional installation process of integrated thermal insulation panels, the mating of screw-in expansion bolts with anchors requires multiple steps, including marking lines for positioning, drilling holes to embed plastic expansion tubes, secondary alignment and installation of anchors, and tightening with self-tapping screws. This process involves repetitive positioning operations. When applied to low-density walls such as aerated concrete blocks, the frictional resistance between the expansion bolts and the wall decreases significantly, making it difficult for the anchors to meet the pull-out strength specified in GB / T 30595-2014 "Anchoring Connections for Building Curtain Walls," thus affecting the reliability of the connection between the external insulation system and the building's main structure.

[0016] For example, in high-rise building exterior wall insulation projects, when aerated concrete blocks are used as the base wall, the construction team installs anchors using traditional methods. After drilling, a gap of 0.5-1.2mm exists between the plastic expansion tube and the hole wall, resulting in incomplete filling. During the subsequent screwing in of self-tapping screws, the expansion tube is prone to radial displacement, failing to generate effective expansion pressure. At this point, the actual contact area between the anchor and the wall is only 60%-70% of the theoretical value. In wind load tests, multiple anchor points experience slippage failure below 5kN, far below the standard requirement of 6.3kN tensile strength limit.

[0017] If the above problems are not addressed, the external insulation system will face the risk of complete detachment, especially in typhoon-prone areas or high-rise buildings in areas with negative wind pressure. Anchoring failure could trigger a chain reaction of damage. Furthermore, the extended construction period caused by repeated repositioning will increase the safety risks of working at heights, and the construction waste generated during rework and repair will significantly increase the total life-cycle maintenance costs.

[0018] Faced with the aforementioned problems, this application first considers how to simplify the multiple repetitive positioning steps in traditional processes and improve the pull-out resistance of anchors in low-density walls. Analysis revealed that the separate installation of traditional expansion screws and anchors leads to poor positioning accuracy, and the inability to effectively fill the gap between the plastic expansion tube and the hole wall is the key reason for insufficient contact area. To address this, this application attempts to integrate the expansion mechanism with the positioning function, designing an integrally molded positioning plate structure. The positioning cylinder directly guides the insertion path of the expansion screw, avoiding secondary alignment errors. Simultaneously, a rotary expansion screw forms a frictional self-locking mechanism with the positioning cylinder. The rotational expansion force of the rotary nut section forces three-dimensional compressive stress between the outer wall of the positioning cylinder and the wall hole wall, thereby increasing the contact area. To solve the connection stability problem between the installation strip and the positioning plate, the length of the positioning cylinder is further set to be greater than the thickness of the vertical end of the installation strip, allowing the tail of the expansion screw to fully embed into the deep, dense area of ​​the base wall. A stepped groove structure ensures that the gasket and installation strip form surface contact for pressure bearing.

[0019] As shown in Figures 1-4, this application proposes a rotary expansion anchor integrated plate installation structure, including an L-shaped installation strip 1, a rotary expansion screw 2, and a positioning plate. The positioning plate is integrally formed by a washer 3 and a positioning cylinder 4. The outer diameter of the washer 3 is larger than the cross-sectional diameter of the positioning cylinder 4, and the inner diameter of the washer 3 is the same as the inner diameter of the positioning cylinder 4. The expansion fixing end of the rotary expansion screw 2 passes through the washer 3 and the positioning cylinder 4 and is placed in the base wall. The rotary nut section of the rotary expansion screw 2 abuts against the washer 3. The vertical end surface of the L-shaped installation strip 1 is provided with an installation hole 5. The diameter of the installation hole 5 is adapted to the cross-sectional diameter of the positioning cylinder 4, and the length of the positioning cylinder 4 is greater than the vertical end thickness of the L-shaped installation strip 1. The horizontal end surface of the L-shaped installation strip is provided with a fixing hole 6.

[0020] The L-shaped mounting strip 1 refers to a metal or plastic component with mutually perpendicular vertical and horizontal ends. It can be manufactured using stamping or injection molding processes. The vertical end is used to fix the positioning cylinder 4, and the horizontal end is used to connect the integrated insulation panel. In this design, the load-bearing and fixing functions are separated, reducing installation complexity. The rotary expansion screw 2 refers to a fastener with a threaded expansion structure, which can be achieved using a metal screw and an expandable sleeve. The expansion fixing end passes through the positioning plate and embeds into the wall. The rotary nut section generates axial pressure through rotation, and in this design, mechanical self-locking enhances the anchoring force. The positioning plate is an integrally formed component of the gasket 3 and the positioning cylinder 4, which can be manufactured using welding or casting processes. The gasket 3 restricts the horizontal displacement of the positioning cylinder 4. The positioning cylinder 4 passes through the vertical end of the L-shaped mounting strip 1 and extends to the base wall. In this design, precise guidance ensures the expansion screw is aligned with the mounting hole 5. The mounting hole 5 is a through hole opened at the vertical end of the L-shaped mounting strip 1, which can be achieved by drilling or laser cutting. The hole diameter matches the outer diameter of the positioning cylinder 4. In this design, a clearance fit allows the positioning cylinder 4 to be inserted to form a vertical support. The fixing hole 6 is a through hole opened at the horizontal end of the L-shaped mounting strip 1, which can be achieved by stamping or milling. It is used to connect the integrated insulation panel with rivets or screws. In this design, the construction efficiency is improved by separating the anchoring and panel fixing steps. The core innovation of this application lies in combining the positioning piece with the L-shaped mounting strip 1, through the positioning cylinder 4...

[0021] The installation path of the rotary expansion bolt 2 is precisely guided, while the pressure of the nut is dispersed by the washer 3, so that the expansion bolt forms a stable anchor in the loose wall, thereby simplifying the construction process and improving the reliability of the anchor.

[0022] The working process and principle of this application are as follows: The rotary expansion anchor integrated plate installation structure includes an L-shaped installation strip 1, a rotary expansion screw 2, and a positioning plate. The positioning plate is integrally formed by a washer 3 and a positioning cylinder 4. The outer diameter of the washer 3 is larger than the cross-sectional diameter of the positioning cylinder 4, and the inner diameter of the washer 3 is the same as the inner diameter of the positioning cylinder 4. The expansion fixing end of the rotary expansion screw 2 passes through the washer 3 and the positioning cylinder 4 and is placed in the base wall, with the rotary nut section abutting against the washer 3. The vertical end surface of the L-shaped installation strip 1 is provided with an installation hole 5, the diameter of which is adapted to the cross-sectional diameter of the positioning cylinder 4, and the length of the positioning cylinder 4 is greater than the thickness of the vertical end of the L-shaped installation strip 1. The horizontal end surface of the L-shaped installation strip 1 is provided with a fixing hole 6.

[0023] During installation, first place the positioning plate into the pre-drilled hole in the base wall, and then embed the positioning cylinder 4 into the hole. Next, pass the rotary expansion screw 2 through the positioning plate, allowing the expansion fixing end to enter the base wall. The rotary nut section 9 abuts against the washer 3, and rotating the screw causes the expansion fixing end to expand and fix within the wall. The L-shaped mounting strip 1 is installed through the mounting hole 5 and engages with the positioning cylinder 4. The length of the positioning cylinder 4 is greater than the thickness of the mounting strip to ensure a secure connection. Finally, fix the integrated plate through the fixing hole 6 at the horizontal end of the L-shaped mounting strip 1.

[0024] The key to this structure lies in the design of the positioning plate. The gasket 3 and the positioning cylinder 4 are integrally molded, improving positioning accuracy. The length of the positioning cylinder 4 is greater than the thickness of the mounting strip, increasing the embedding depth. The rotary expansion screw 2 cooperates with the positioning cylinder 4, utilizing the rotational expansion force of the rotary nut section to generate three-dimensional compressive stress between the outer wall of the positioning cylinder 4 and the wall of the hole, increasing the contact area and improving the anchoring strength.

[0025] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0026] First, pre-drill holes in the base wall according to the design positions. Place the positioning plate in the pre-drilled hole, embed the positioning cylinder 4 into the hole, and fit the washer 3 against the wall surface. Then, pass the rotary expansion screw 2 through the positioning plate, so that the expansion fixing end enters the base wall. Rotate the screw so that the rotary nut section abuts against the washer 3, and at the same time, the expansion fixing end expands and fixes itself in the wall.

[0027] Next, align the mounting hole 5 of the L-shaped mounting strip 1 with the positioning cylinder 4, and push the mounting strip in so that the positioning cylinder 4 passes through the mounting hole 5. Since the length of the positioning cylinder 4 is greater than the thickness of the vertical end of the mounting strip, the positioning cylinder 4 will protrude from the surface of the mounting strip. Finally, fix the integrated insulation panel to the mounting strip through the fixing hole 6 at the horizontal end of the L-shaped mounting strip 1.

[0028] During installation, the installation height and flatness of the integrated panel can be finely adjusted by adjusting the position of the L-shaped mounting strip 1 on the positioning cylinder 4. The fixing holes 6 can be fitted with appropriate fixing methods as needed, such as screws or rivets.

[0029] Through the above solutions, this application achieves the goals of simplifying installation procedures, improving positioning accuracy, and enhancing anchoring strength. The integrated design of the positioning piece avoids the problem of repeated positioning in traditional processes, thus improving construction efficiency. The cooperation between the rotary expansion bolt 2 and the positioning cylinder 4 increases the contact area with the wall, significantly improving the pull-out resistance in low-density walls. The cooperation design between the L-shaped installation strip 1 and the positioning cylinder 4 increases connection stability, ensuring a reliable connection between the external insulation system and the main building structure. These improvements effectively solve the problem of insufficient anchoring strength in low-density walls such as aerated concrete using traditional processes, improving the safety and durability of the external insulation system.

[0030] In some of the above-mentioned solutions in this application, the horizontal end surface of the L-shaped installation strip 1 is provided with fixing holes 6 for connecting the integrated metal insulation panel 8. However, in the actual installation process, due to the limitations of the panel size error or the unevenness of the base wall, the connection position between the fixing hole 6 and the side of the panel is prone to deviation, resulting in reduced installation efficiency.

[0031] This application further proposes that the fixing hole 6 be set as a waist-shaped hole.

[0032] The long axis of the oblong hole extends along the horizontal length of the L-shaped mounting strip 1, forming a horizontal adjustment space. The inner wall of the oblong hole has a smooth transition, with semi-circular arc structures on both sides and a parallel straight edge structure in the middle. The length-to-width ratio of the oblong hole is 3:1 to 5:1, with the specific length determined according to the installation error range. When used in conjunction with the pull-out rivet 7, the rivet can move along its long axis within the hole to achieve horizontal position adjustment.

[0033] Specifically, during installation, when the side of the integrated metal insulation panel 8 is fixedly connected to the horizontal end of the L-shaped mounting strip 1 via pull-out rivets 7, the oblong hole provides horizontal movement allowance for the rivet. If the panel's installation position shifts due to processing errors or wall tilt, the rivet can be adjusted to the corresponding position along the long axis of the oblong hole, avoiding the need for re-drilling or replacing the mounting strip. For example, when the oblong hole length is set to 15 mm, the panel can be adjusted within a range of ±7.5 mm. Therefore, strict alignment of the panel and fixing hole 6 is not required during installation, reducing construction difficulty. Furthermore, the oblong hole structure maintains connection stability after adjustment through the contact surface between the rivet and the hole wall, preventing the panel from loosening in the horizontal direction.

[0034] As a preferred embodiment, the solution of this application is implemented as follows: The fixing hole 6 is a slotted hole. The long axis of the slotted hole is parallel to the horizontal length direction of the L-shaped mounting strip 1. The length of the slotted hole is 20mm and the width is 8mm. Both ends of the slotted hole are semi-circular. There are multiple slotted holes, which are evenly distributed along the horizontal end of the L-shaped mounting strip 1.

[0035] Through the above technical solution, this application achieves an adjustable connection between the L-shaped mounting strip 1 and the integrated metal insulation panel 8. The slotted hole design allows for fine-tuning of the L-shaped mounting strip 1 in the horizontal direction, thereby adapting to different installation requirements and wall conditions. This adjustability improves the flexibility and accuracy of installation, helping to solve potential errors during installation. Simultaneously, the slotted hole design also reduces stress concentration during installation, improving the stability and durability of the overall structure.

[0036] In some of the solutions described above in this application, the fit between the mounting hole 5 and the positioning cylinder 4 may be compromised due to the inability of the gasket 3 to effectively limit the movement, resulting in loose contact between the swivel nut and the gasket 3 during installation, which in turn affects the stability of the overall structure.

[0037] This application further proposes that the mounting hole 5 is a stepped groove hole, and the gasket 3 is placed in the large end hole of the stepped groove hole.

[0038] The inner diameter of the large end of the stepped slot matches the outer diameter of the gasket 3, ensuring that the gasket 3 is fully embedded in the hole. The inner diameter of the small end of the stepped slot matches the outer diameter of the positioning cylinder 4, limiting the radial displacement of the positioning cylinder 4. The height of the large end of the mounting hole 5 is the same as the thickness of the gasket 3, so that the surface of the gasket 3 is flush with the end face of the mounting hole 5 after it is embedded. Through the segmented structure of the stepped slot, the gasket 3 is confined within the large end hole, preventing it from tilting or shifting during installation.

[0039] Specifically, when installing the L-shaped mounting strip 1, the positioning cylinder 4 passes through the small end hole of the stepped groove into the base wall, and the washer 3 is pre-positioned in the large end hole. After the expansion fixing end of the rotary expansion bolt 2 passes through the washer 3 and the positioning cylinder 4, the rotary nut section tightly abuts against the surface of the washer 3. Because the washer 3 is confined within the large end hole, its position will not shift due to tightening of the bolt. The height of the large end hole of the stepped groove is consistent with the thickness of the washer 3, further ensuring that the washer 3 remains horizontal after insertion, avoiding localized stress concentration. This structure improves the contact stability between the washer 3 and the rotary nut through physical restraint, thereby enhancing the overall tensile strength of the anchoring system.

[0040] As a preferred embodiment, the solution of this application is implemented as follows: the mounting hole 5 is configured as a stepped groove, and the gasket 3 is placed inside the large end hole of the stepped groove. The stepped groove includes a large end hole and a small end hole, with the diameter of the large end hole being larger than the diameter of the small end hole. The outer diameter of the gasket 3 matches the diameter of the large end hole, and the outer diameter of the positioning cylinder 4 matches the diameter of the small end hole. During installation, the gasket 3 is first placed into the large end hole of the stepped groove, and then the positioning cylinder 4 is passed through the small end hole. This design allows the gasket 3 to be securely embedded in the vertical end of the L-shaped mounting strip 1, while the positioning cylinder 4 can accurately pass through the L-shaped mounting strip 1.

[0041] Through the above technical solution, this application achieves a stable connection between the gasket 3 and the L-shaped mounting strip 1, improving the overall structural stability. The stepped slot design allows the gasket 3 to be fully embedded within the L-shaped mounting strip 1, avoiding potential interference from exposed parts. Simultaneously, this design simplifies the installation process, reduces installation errors, and improves installation efficiency and accuracy.

[0042] In some of the above-mentioned solutions in this application, the mounting hole 5 adopts a stepped groove structure, and the gasket 3 is placed in the large end hole. However, due to the deviation between the thickness of the gasket 3 and the height of the large end hole, the gasket 3 may not be fully embedded in the hole during installation, which affects the clamping effect of the rotary expansion screw 2 and the positioning cylinder 4, thereby reducing the stability of the overall structure.

[0043] This application further proposes that the thickness of the gasket 3 is the same as the height of the large end hole of the stepped slot.

[0044] The height of the large end of the stepped slot is set to be equal to the thickness of the gasket 3, forming a tight fit. The outer diameter of the gasket 3 is larger than the cross-sectional diameter of the positioning cylinder 4, while the inner diameter of the gasket 3 is consistent with the inner diameter of the positioning cylinder 4. The expansion fixing end of the rotary expansion screw 2 passes through the gasket 3 and the positioning cylinder 4 and enters the base wall, where the rotary nut section contacts the gasket 3.

[0045] Specifically, when the height of the large end hole of the stepped groove is the same as the thickness of the washer 3, after the washer 3 is embedded in the large end hole, its upper and lower surfaces are completely in contact with the stepped surface of the stepped groove and the outer surface of the vertical end of the L-shaped mounting strip 1, respectively. During the tightening process of the rotary nut section, the washer 3 is subjected to uniform axial pressure, avoiding local stress concentration due to thickness deviation. The length of the positioning cylinder 4 is greater than the thickness of the vertical end of the L-shaped mounting strip 1, so that the end of the positioning cylinder 4 can remain exposed after installation, ensuring the anchoring depth of the expansion bolt to the base wall. This size matching method eliminates the gap between the washer 3 and the stepped groove, allowing the tightening force of the rotary nut section to be completely transmitted to the positioning cylinder 4 through the washer 3, effectively improving the tensile strength of the anchoring structure.

[0046] As a preferred embodiment, the solution of this application is implemented as follows: the thickness of the gasket 3 is the same as the height of the large end hole of the stepped groove. For example, the thickness of the gasket 3 can be set to 5 mm, and the height of the large end hole of the stepped groove can also be set to 5 mm. This design allows the gasket 3 to be completely embedded in the large end hole of the stepped groove, flush with the surface of the L-shaped mounting strip 1.

[0047] Through the above technical solution, this application achieves a tight fit between the gasket 3 and the L-shaped mounting strip 1, avoiding gaps between them and improving the stability of the installation structure. At the same time, the flush design of the surfaces of the gasket 3 and the L-shaped mounting strip 1 makes the entire installation structure more aesthetically pleasing and reduces potential safety hazards caused by protruding parts.

[0048] In some of the above-mentioned solutions in this application, the horizontal end surface of the L-shaped installation strip 1 is provided with fixing holes 6 for connecting the integrated metal insulation panel 8. However, the traditional process of using self-tapping screws for fastening has problems of low installation efficiency and insufficient connection strength, especially in the case of loose wall conditions, the anchor tension is difficult to meet the standard.

[0049] This application further proposes that a pull-out rivet 7 be installed in the fixing hole 6, and the side of the integrated metal insulation panel 8 is fixedly connected to the horizontal end of the L-shaped mounting strip 1 by the pull-out rivet 7.

[0050] The diameter of the shank of the pull-out rivet 7 matches the inner diameter of the fixing hole 6, while the diameter of the rivet head is larger than the diameter of the fixing hole 6 to prevent it from coming loose. The pull-out rivet 7 is made of carbon steel or aluminum alloy, and its surface can be galvanized to improve corrosion resistance. The installation direction of the pull-out rivet 7 is perpendicular to the horizontal end surface of the L-shaped mounting strip 1, and a gapless connection between the integrated metal insulation panel 8 and the mounting strip is achieved through mechanical riveting.

[0051] When the fixing hole 6 is a slotted hole, the pull-wire rivet 7 can be adjusted along the length of the slotted hole to adapt to the assembly requirements of metal insulation integrated panels 8 of different sizes.

[0052] Specifically, after the pull-thread rivet 7 passes through the pre-drilled hole on the side of the integrated metal insulation panel 8 and the fixing hole 6 at the horizontal end of the L-shaped mounting strip 1, axial pressure is applied to the tail of the rivet using a special tool, causing it to undergo plastic deformation and form an upset head, thereby pressing and fixing the two together. The increased contact area between the rivet upset head and the surface of the integrated metal insulation panel 8 effectively disperses the anchoring load and avoids connection failure caused by local stress concentration. This connection method does not require pre-embedded plastic expansion tubes or step-by-step tightening of self-tapping screws; installation can be completed in a single riveting operation, simplifying the operation steps while improving the stability of the connection strength. By adjusting the diameter and number of pull-thread rivets 7, the weight and wind pressure load requirements of different specifications of integrated metal insulation panels 8 can be matched. Especially in low-strength base walls such as aerated concrete blocks, the riveting method with multi-point uniform force distribution can ensure the overall reliability of the anchoring system.

[0053] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0054] A pull-out rivet 7 is installed inside the fixing hole 6. The side of the integrated metal insulation panel 8 is fixedly connected to the horizontal end of the L-shaped mounting strip 1 by the pull-out rivet 7. The pull-out rivet 7 consists of a rivet body and a pull core. The rivet body is inserted into the fixing hole 6 and the pre-drilled hole in the integrated metal insulation panel 8, and the pull core passes through the rivet body. By pulling the pull core with a special tool, the rivet body deforms and expands, thereby fastening the L-shaped mounting strip 1 and the integrated metal insulation panel 8 together. The specifications of the pull-out rivet 7 can be selected according to actual needs, such as an aluminum pull-out rivet 7 with a diameter of 4mm and a length of 12mm.

[0055] Through the above technical solution, this application achieves a quick and reliable connection between the integrated metal insulation panel 8 and the L-shaped mounting strip 1. The use of pull-out rivets 7 simplifies the installation process, eliminating the need for additional bolts or welding. Simultaneously, pull-out rivets 7 provide sufficient connection strength to ensure that the integrated metal insulation panel 8 will not loosen or fall off during use. Furthermore, the installation of pull-out rivets 7 facilitates later maintenance and replacement, improving the maintainability of the overall structure.

[0056] In some of the solutions described above in this application, when fixing the integrated metal insulation panel 8 with the L-shaped mounting strip 1, it is necessary to ensure that the horizontal position is accurate during the installation process. Traditional methods require repeated adjustments using an external level, which reduces installation efficiency.

[0057] This application further proposes that the L-shaped mounting strip 1 is magnetically equipped with a level.

[0058] The level is magnetically attached to the surface of the L-shaped mounting strip 1, allowing for quick positioning and removal during installation. The contact surface between the level and the L-shaped mounting strip 1 is provided with a magnetic material layer, which can be fixed to the surface of the mounting strip by adhesive or embedding. The dimensions of the level are matched to the installation area of ​​the L-shaped mounting strip 1 to avoid interference with other components.

[0059] Specifically, during installation, the level is magnetically attached to the horizontal or vertical end of the L-shaped mounting strip 1. Workers adjust the strip's orientation in real-time by observing the bubble position on the level. Once adjusted, the level can be removed directly without dismantling or loosening the fixed structure. This design allows the leveling process to be completed simultaneously with the installation, reducing repetitive adjustments. The magnetic attachment of the level avoids the need for additional holes on the mounting strip surface, maintaining structural integrity. For example, a strong magnet can be integrated inside the level, its magnetic force sufficient to resist vibrations or displacements generated during installation, ensuring calibration accuracy.

[0060] As a preferred embodiment, the solution of this application is implemented as follows: A level is magnetically attached to the L-shaped mounting strip 1. The level is a small electronic level with a built-in magnet. A magnetic material coating is applied to the outer surface of the vertical end of the L-shaped mounting strip 1. During installation, the electronic level is magnetically attached to the outer surface of the vertical end of the L-shaped mounting strip 1. The levelness of the L-shaped mounting strip 1 is adjusted by observing the angle value displayed by the electronic level. After adjustment, the electronic level is removed, and subsequent fixing steps are performed.

[0061] Through the above technical solution, this application can quickly and accurately adjust the levelness of the L-shaped installation strip 1, improving installation accuracy. Meanwhile, the magnetic design allows the level to be reused, avoiding one-time consumption and reducing installation costs. Furthermore, the electronic level is compact and does not interfere with subsequent installation operations, improving construction efficiency.

[0062] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
