Description

Technical Field

[0001] This utility model relates to the field of wall decoration technology, and in particular to a prefabricated wall keel base leveling structure. Background Technology

[0002] One of the factors affecting the quality of wall decoration is the flatness of the substrate, which is generally achieved through leveling structures.

[0003] Currently, the common method for leveling wall surfaces involves applying materials such as cement mortar or gypsum mortar to the wall surface and then manually scraping and grinding it to achieve the required flatness. This method has the drawbacks of long construction cycles, high material consumption, and a tendency to cause problems such as hollowing and cracking.

[0004] To address the aforementioned technical issues, those skilled in the art have proposed using light steel or wooden keels as the base framework, along with fine-tuning screws, to allow for vertical and horizontal adjustments during installation to accommodate uneven walls or ensure the keel's top surface remains level. However, to meet the specific requirements of leveling accuracy, load-bearing capacity, or special wall structures in certain projects, it is sometimes necessary to manufacture certain key leveling components in the keel system using custom molds. This not only increases the production cost per unit but also results in poor adaptability and insufficient versatility. Furthermore, some existing leveling structures lack stability under long-term loads or external disturbances, easily becoming loose or slipping, which can lead to deformation or subsidence of the originally leveled base layer, affecting the final effect and service life of the decorative layer. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a prefabricated wall keel base leveling structure. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the detailed description that follows.

[0006] The present invention adopts the following technical solution:

[0007] A prefabricated wall keel base leveling structure is provided, comprising: several rows of leveling components arranged sequentially from top to bottom on the wall, each row of leveling components consisting of several leveling nuts, and leveling bolts provided on the leveling nuts; each leveling nut includes: a resin fixing base and a pull nut, the resin fixing base having an installation through hole, the inner end of the pull nut being fixed in the installation through hole, and the leveling bolt being threadedly connected to the outer end of the pull nut; each leveling bolt includes: a bolt body, the bolt body having a hexagonal groove extending through the bolt body.

[0008] Furthermore, the resin fixing base has a disc-shaped structure, and a circular mounting through hole is provided at the center of the resin fixing base. The pull nut has a cylindrical structure, and a threaded groove is provided on the outer end face of the pull nut.

[0009] Furthermore, the resin fixing base has first circular holes on the left and right sides of the mounting through hole, and second circular holes on the upper and lower sides of the mounting through hole, wherein the diameter of the first circular hole is larger than the diameter of the second circular hole.

[0010] Furthermore, the hexagonal groove is a columnar channel with a regular hexagonal cross-section, and the hexagonal groove extends from the inner end face of the bolt body to the outer end face of the bolt body.

[0011] Furthermore, the leveling bolt also includes: a mounting end cap, which is disposed at the outer end of the bolt body, and the mounting end cap has an adjustment hole that is connected to and has the same outline as the hexagonal column groove. A limiting plate extending towards the inner end of the bolt body is provided at the edge of the mounting end cap.

[0012] Furthermore, the prefabricated wall keel base leveling structure further includes: a channel-shaped keel, wherein the installation end cap is embedded in the U-shaped channel of the channel-shaped keel, and an elongated adjustment hole is provided on the channel-shaped keel at the position corresponding to the leveling bolt.

[0013] The beneficial effects of this utility model are:

[0014] 1. The leveling nut is broken down into a resin fixing base and a rivet nut. The resin fixing base does not need to be molded separately for each project, reducing material manufacturing costs. The rivet nut can be replaced with different specifications as needed, so that the whole system can flexibly adapt to the needs of different projects and different wall conditions, improving adaptability.

[0015] 2. The design of the hexagonal groove inside the leveling bolt allows for the injection of a slow-release gel. After curing, the gel bonds the leveling nut and the leveling bolt together, effectively preventing bolt loosening and rotation caused by vibration, load, or the passage of time, and improving the overall stability and durability of the leveling keel base.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] like Figure 1-9 As shown in some illustrative embodiments, a prefabricated wall keel base leveling structure is provided to solve the problems of high cost, poor adaptability, and insufficient stability in existing wall leveling technologies. Specifically, it includes: several rows of leveling components arranged sequentially on the wall from top to bottom. Each row of leveling components consists of several evenly distributed leveling nuts 100. The arrangement of the leveling nuts 100 is planned according to the original flatness of the wall and the layout of the subsequent keel to ensure that the ideal base flatness can be achieved in the end.

[0028] The leveling nut 100 includes: a resin fixing base 110 and a pull nut 120.

[0029] The resin mounting base 110 directly contacts and fixes itself to the wall. The choice of resin material gives the base a certain degree of flexibility and insulation, while also keeping costs relatively low. The resin mounting base 110 has a disc-shaped structure, and a circular mounting through hole 111 is provided at the center of the resin mounting base 110 to accommodate and fix the rivet nut 120.

[0030] The resin mounting base 110 has two first circular holes 112 on the left and right sides of the mounting through hole 111, and two second circular holes 113 on the top and bottom sides. The diameter of the first circular holes 112 is larger than the diameter of the second circular holes 113. The structural design and arrangement of the first circular holes 112 and the second circular holes 113 provide options for multiple fixing methods and offer more flexible installation methods on different wall materials. For example, the larger hole diameter can be used with expansion bolts of different diameters, while the smaller hole diameter can be used for self-tapping screws or specific anchors.

[0031] The inner end of the pull nut 120 is fixed within the mounting through hole 111, with the inner end referring to the end facing the wall. Specifically, the inner end of the pull nut 120 is fixed to the mounting through hole 111 of the resin fixing base 110 using a riveting process. Riveting is an existing connection method that can securely fix the metal pull nut 120 to the non-metallic resin fixing base 110. The pull nut 120 has a cylindrical structure, and its outer end face has a threaded groove 121 for threaded connection with the leveling bolt 200.

[0032] A leveling bolt 200 is provided on the leveling nut 100. The leveling bolt 200 includes: a bolt body 210 and a mounting end cap 220.

[0033] A hexagonal groove 211 is provided on the bolt body 210, and the hexagonal groove 211 passes through the bolt body 210. The hexagonal groove 211 is a columnar channel with a regular hexagonal cross section. The hexagonal groove 211 passes through the inner end face of the bolt body 210 to the outer end face of the bolt body 210. The inner end of the bolt body 210 refers to the end that is connected to the leveling nut 100.

[0034] The first function of the hexagonal groove 211 is to provide a drive interface: the hexagonal groove 211 extends from the inner end face of the bolt body 210 to the outer end face, allowing for direct rotation using a standard hexagonal wrench or drill bit, making the adjustment process convenient and quick.

[0035] The second function of the hexagonal groove 211 is to achieve structural reinforcement and prevent loosening: Since the hexagonal groove 211 is hollow, its hexagonal inner wall can be used as a channel to inject a slow-release gel. After the gel cures, it tightly bonds the leveling nut 100 and the leveling bolt 200 together, forming a solid whole. This not only prevents the leveling bolt 200 from loosening or rotating due to vibration or stress during use, greatly improving the overall stability of the leveling keel base, but also resists shear force to a certain extent.

[0036] The bolt body 210 has external threads on its exterior for engagement with the threaded groove 120 on the rivet nut.

[0037] A prefabricated wall keel base leveling structure further includes: a channel-shaped keel 300, which is made of light steel or aluminum alloy and has a standard U-shaped cross-section. The channel-shaped keel 300 is fastened onto the mounting end cap 220 of the leveling bolt. The surface of the channel-shaped keel 300 can be fixed with gypsum board or other decorative panels. The mounting end cap 220 is embedded in the U-shaped channel of the channel-shaped keel 300, and the channel-shaped keel 300 has elongated adjustment holes 310 at positions corresponding to the leveling bolts 200.

[0038] The mounting end cap 220 is located at the outer end of the bolt body 210 to provide support and positioning for the grooved keel 300. The mounting end cap 220 has an adjustment hole 221 that is connected to the hexagonal column groove 211 and has the same outline. This allows the bolt body 210 to be rotated through the elongated adjustment hole 310 on the back of the grooved keel 300 to adjust the depth of the leveling bolt 200 screwed into the leveling nut 100, thereby achieving concealed secondary leveling.

[0039] A limiting plate 222 extending toward the inner end of the bolt body 210 is provided at the edge of the mounting end cover 220. The limiting plate 222 can prevent the channel keel 300 from moving or falling off relative to the leveling bolt 200 during installation or use, ensuring the stable installation of the keel.

[0040] Installation steps:

[0041] Assemble the leveling nut 100: First, use a rivet gun to fix the rivet nut 120 into the mounting through hole 111 of the resin fixing base 110. This step can be prefabricated in the factory or completed on site. The advantage is that the rivet nut 120 is a standardized metal part, which can improve the overall strength of the leveling nut 100. Moreover, the resin fixing base 110 does not need to be molded separately for each project, which greatly saves mold costs and time and improves the adaptability of the project.

[0042] Wall treatment and positioning: The original structural wall surface is cleaned and treated as necessary. Then, according to the design requirements and the actual situation of the wall, the fixing points of the leveling nut 100 are determined, and precise positioning lines are drawn on the wall surface.

[0043] Install the leveling nut 100: Fix the assembled leveling nut 100 to the wall according to the positioning line. The fixing method depends on the wall material. For example, expansion bolts can be used on concrete or brick walls, and self-tapping screws can be used on thin plates or other lightweight walls. The multiple round holes on the resin fixing base 110 provide different fixing options, increasing flexibility.

[0044] Install the leveling bolt 200: Screw the leveling bolt 200 into the rivet nut 120 part of the leveling nut 100 fixed on the wall. At this time, a preliminary leveling operation can be performed so that the bolt body 210 is roughly in the required position.

[0045] Install the channel keel 300: Attach the channel keel 300 to the mounting end cap 220 of the leveling bolt 200, so that its U-shaped channel faces the wall. At this time, the hexagonal column groove 211 opened on the leveling bolt will be exposed through the adjustment hole 221 on the mounting end cap 220 and located in the elongated adjustment hole 310 opened on the channel keel 300. The position of the channel keel 300 can be precisely adjusted by rotating the leveling bolt 200 until the ideal flatness is achieved. The limiting plate 222 ensures the stability of the keel.

[0046] The prefabricated wall keel base leveling structure of this application has the following advantages:

[0047] 1. High cost-effectiveness and strong adaptability: The leveling nut 100 is decomposed into a resin fixing base 110 and a rivet nut 120. The resin fixing base 110 does not need to be molded separately for each project, which significantly reduces material and manufacturing costs. The rivet nut 120 is a universal part and can be replaced with different specifications as needed, so that the whole system can flexibly adapt to the needs of different projects and different wall conditions, greatly improving market adaptability.

[0048] 2. High structural stability: The design of the hexagonal groove 211 inside the leveling bolt 200 allows for the injection of a slow-release gel. After curing, the gel bonds the leveling nut 100 and the leveling bolt 200 together, effectively preventing bolt loosening and rotation caused by vibration, load, or the passage of time. This greatly improves the overall stability and durability of the leveling keel base layer, ensuring the long-term reliability of the wall decoration effect.

[0049] 3. Prefabricated, efficient and convenient installation: The entire system is composed of prefabricated standard parts, which reduces the amount of on-site assembly work and makes it easy to install. In particular, the design of secondary fine adjustment through the elongated adjustment hole 310 on the back of the channel keel 300 makes precise leveling easier to achieve, reduces the time spent on repeated adjustments, and improves construction efficiency.

[0050] 4. Strong precision leveling capability: By rotating the leveling bolt 200, the position of each support point can be precisely controlled, effectively compensating for the unevenness of the original wall surface. The multi-row, multi-point arrangement, combined with precise adjustment, can achieve a highly flat keel base.

[0051] 5. Flexible design with multiple installation options: The round holes of different diameters on the resin fixing base 110 provide convenience for selecting the most suitable fixing method on different wall materials, enhancing the system's versatility.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
