A reinforcement structure for cracked corners of suspended ceilings

Abstract

This utility model relates to the field of ceiling corner reinforcement technology and discloses a ceiling corner crack reinforcement structure, including a lightweight keel, a locking structure including a mounting block, the mounting block being installed inside the mounting groove by bolts, the outer surface of the mounting block having a threaded hole, the threaded hole having a screw threadedly connected to the inside, one end of the screw having a pressing block, and an expansion kit being installed inside the sliding groove, with the pressing block located inside the expansion kit. This utility model utilizes the pressing block to drive the expansion kit and the arc-shaped piece to form a double radial pressure, so that the load is transmitted through surface contact static friction rather than thread engagement, fundamentally eliminating the continuous metal contact interface and destroying the necessary conditions for electrochemical corrosion. During disassembly, rotating the knob counterclockwise directly releases the radial pressure instead of overcoming the resistance of thread corrosion, causing the expansion kit and the arc-shaped piece to contract synchronously and detach from the inner wall of the sliding groove. Even in a humid environment for a long time, oxides only adhere to the non-mating surfaces and do not hinder the release stroke.

Description

Technical Field

[0001] This utility model relates to the field of ceiling corner reinforcement technology, specifically a ceiling corner crack reinforcement structure. Background Technology

[0002] When renovating a house, ceiling installation is a very important part of interior decoration. The installation process usually involves first installing a lightweight ceiling on the part of the ceiling where the ceiling needs to be installed. At the bottom of the four L-shaped corners of the lightweight keel, white latex and self-tapping screws are used to fix the ceiling cover plate that matches the area of ​​the lightweight keel. After the lightweight keel at the four corners is installed, the ceiling cover plate is used to connect the ceiling panels between adjacent corners. Finally, plasterboard is laid on the ceiling and then plastered.

[0003] The utility model patent application with publication number "CN220414646U" discloses a ceiling corner cracking reinforcement structure, which is mainly composed of lightweight keel, ceiling cover plate, load-bearing reinforcement plate and load-bearing components. This technical solution has the effect of reducing the occurrence of cracks at the corners of the ceiling.

[0004] The ceiling corner cracking reinforcement structure disclosed in the aforementioned document has the following defects: The load-bearing components in this ceiling corner cracking reinforcement structure consist of load-bearing columns and load-bearing rods. In use, the load-bearing columns are fixed to the ceiling at the open end of the lightweight keel, and then the load-bearing rods are rotated into the load-bearing columns by hand while holding the ceiling cover plate. After the load-bearing rods are tightened, they can further support the corner of the lightweight keel. However, the fully threaded rigid fit between the load-bearing rods and the load-bearing columns undergoes electrochemical corrosion in the humid space of the ceiling. Expansive oxides are generated at the metal interface, blocking the thread gaps, resulting in a sharp increase in unscrewing resistance during disassembly, making disassembly difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement structure for cracked corners of suspended ceilings, which solves the problem that in existing reinforcement structures for cracked corners of suspended ceilings, the fully threaded rigid fit between the load-bearing rod and the load-bearing column will undergo electrochemical corrosion in the humid space of the ceiling, and the metal interface will generate expansive oxides that block the thread gaps, resulting in a sharp increase in unscrewing resistance during disassembly and making disassembly difficult.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a reinforcement structure for cracked corners in suspended ceilings, comprising a lightweight keel, a ceiling cover plate mounted on the lower surface of the lightweight keel, a load-bearing component inside the lightweight keel, a load-bearing column, an extension seat on the upper surface of the load-bearing column, a sliding groove on the lower surface of the load-bearing column, a load-bearing rod slidably connected inside the sliding groove, an installation groove at the upper end of the load-bearing rod, a locking structure inside the installation groove, the locking structure comprising an installation block, the installation block being bolted inside the installation groove, a threaded hole on the outer surface of the installation block, a screw threadedly connected inside the threaded hole, a compression block at one end of the screw, an expansion kit inside the sliding groove, and the compression block located inside the expansion kit.

[0008] Furthermore, one end of the extrusion block is provided with a connecting rod, one end of the connecting rod passes through the expansion kit and is provided with a baffle, and the other end of the screw is fitted with a limiting plate by bolts, the limiting plate being located inside the mounting groove.

[0009] Furthermore, a movable block is threadedly connected to the outer surface of the screw, an opening is provided on the outer surface of the movable block, an arc-shaped piece is provided on the outer surface of the movable block, a connecting plate is provided on the inner surface of the arc-shaped piece, and the connecting plate is slidably connected inside the opening.

[0010] Furthermore, a limiting groove is formed on the outer surface of the screw, and one end of the connecting plate is fitted inside the limiting groove. Anti-slip stripes are formed on the outer surfaces of both the arc-shaped plate and the expansion kit.

[0011] Furthermore, one end of the load-bearing rod passes through the ceiling cover plate and extends downwards. A groove is provided on the lower surface of the ceiling cover plate, and a knob is installed on the lower surface of the load-bearing rod, with the knob located inside the groove.

[0012] Furthermore, the lower end of the ceiling cover is provided with an outer shell, which is interference-fitted into the inside of the groove, and a load-bearing reinforcing plate is installed on the outer surface of the ceiling cover.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model utilizes the extrusion block to drive the expansion kit and the arc plate to form a double radial pressure, so that the load is transmitted through the static friction force of the surface contact rather than the thread engagement, fundamentally eliminating the continuous metal contact interface and destroying the necessary conditions for electrochemical corrosion. When disassembling, rotating the knob counterclockwise directly releases the radial pressure instead of overcoming the resistance of thread corrosion, so that the expansion kit and the arc plate shrink synchronously and detach from the inner wall of the slide. Even if it is in a humid environment for a long time, the oxides only adhere to the non-fitting surface and do not hinder the release stroke.

[0015] (2) By setting the load-bearing reinforcement plate, this utility model can improve the load-bearing capacity of the ceiling cover plate on the lightweight keel, thereby reducing the occurrence of cracks at the corners of the ceiling.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-6 As shown, this utility model is a ceiling corner crack reinforcement structure, including a lightweight keel 1, a ceiling cover plate 2 installed on the lower surface of the lightweight keel 1, a load-bearing component inside the lightweight keel 1, the load-bearing component including a load-bearing column 301, an extension seat 302 provided on the upper surface of the load-bearing column 301, a sliding groove 303 opened on the lower surface of the load-bearing column 301, a load-bearing rod 304 slidably connected inside the sliding groove 303, an installation groove 305 opened at the upper end of the load-bearing rod 304, a locking structure provided inside the installation groove 305, the locking structure including an installation block 401, the installation block 401 is installed inside the installation groove 305 by bolts, a threaded hole opened on the outer surface of the installation block 401, a screw 402 threadedly connected inside the threaded hole, a pressing block 403 provided at one end of the screw 402, an expansion kit 404 provided inside the sliding groove 303, and the pressing block 403 located inside the expansion kit 404;

[0028] One end of the extrusion block 403 is provided with a connecting rod 405. One end of the connecting rod 405 passes through the expansion kit 404 and is provided with a baffle 406. The other end of the screw 402 is installed with a limiting plate 407 by bolts. The limiting plate 407 is located inside the mounting groove 305.

[0029] The outer surface of the screw 402 is threaded with a movable block 408. The outer surface of the movable block 408 is provided with a through-hole. The outer surface of the movable block 408 is provided with an arc-shaped piece 409. The inner surface of the arc-shaped piece 409 is provided with a connecting plate. The connecting plate is slidably connected inside the through-hole.

[0030] By using the extrusion block 403 to drive the expansion kit 404 and the arc plate 409 to form a double radial pressure, the load is transmitted through surface contact static friction rather than thread engagement, fundamentally eliminating the continuous metal contact interface and destroying the necessary conditions for electrochemical corrosion. During disassembly, rotating the load-bearing rod 304 counterclockwise directly releases the radial pressure instead of overcoming the resistance of thread corrosion, causing the expansion kit 404 and the arc plate 409 to contract synchronously and detach from the inner wall of the slide groove 303. Even if it is in a humid environment for a long time, the oxides only adhere to the non-mating surfaces and do not hinder the release stroke.

[0031] A limiting groove 4010 is provided on the outer surface of the screw 402, and one end of the connecting plate is fitted inside the limiting groove 4010. Anti-slip stripes are provided on the outer surfaces of the arc-shaped piece 409 and the expansion kit 404.

[0032] One end of the load-bearing rod 304 passes through the ceiling cover plate 2 and extends downward. A groove is provided on the lower surface of the ceiling cover plate 2. A knob 5 is installed on the lower surface of the load-bearing rod 304. The knob 5 is located inside the groove.

[0033] The lower end of the ceiling cover plate 2 is provided with an outer shell 6, which is interference-fitted into the inside of the groove, and a load-bearing reinforcing plate 7 is installed on the outer surface of the ceiling cover plate 2.

[0034] In use, first fix the pre-fixed lightweight keel 1 to the ceiling. Then, fix the load-bearing column 301 to the ceiling at both ends of the lightweight keel 1 using expansion bolts. Next, apply white latex to the surface of the uncut ceiling cover plate 2 and the bottom wall of the lightweight keel 1. Align the load-bearing rod 304 with the groove of the ceiling cover plate 2 and insert it so that the knob 5 is located in the groove. Then, install the ceiling cover plate 2 on the lower surface of the lightweight keel 1 so that the load-bearing rod 304 is located inside the slide groove 303. By rotating the knob 5 clockwise, the load-bearing rod 304 drives the mounting block 401 to rotate, and the screw 402 pushes axially. As the extrusion block 403 moves upward, it causes the expansion kit 404 to expand radially, making it tightly adhere to the inner wall of the slide groove 303 to form a friction fixation. Simultaneously, the connecting plate of the arc-shaped piece 409 extends outward from the limiting groove 4010, driving the arc-shaped piece 409 to expand outward and press against the inner surface of the slide groove 303. The expansion kit 404 and the arc-shaped piece 409 form a radial and circumferential double locking, achieving rigid anchoring of the load-bearing rod 304 and the load-bearing column 301. Then, the outer shell 6 is installed into the inside of the groove to complete the sealing of the knob 5. Finally, the excess material on the periphery of the ceiling cover plate 2 is removed to complete the reinforcement of the corner of the hanger.

[0035] When it is necessary to remove the ceiling cover plate 2, take the outer shell 6 out of the groove, and then turn the knob 5 in the opposite direction. The power is transmitted to the mounting block 401 through the load-bearing rod 304, driving the screw 402 to retract and move downward along the axis. The pressing block 403 retracts with the screw 402, releasing the radial pressure on the expansion kit 404, so that the expansion kit 404 elastically contracts and disengages from the inner wall of the slide groove 303. At the same time, the connecting plate of the arc-shaped piece 409 slides inward and resets along the limiting groove 4010, so that the arc-shaped piece 409 separates from the slide groove 303. At this time, the load-bearing rod 304 loses its bidirectional constraint and can be pulled vertically downward to detach from the load-bearing column 301. Then the removal of the ceiling cover plate 2 can be carried out.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
