Description

Technical Field

[0001] This utility model specifically relates to a quick-connecting patch for repairing interior ceilings of public buildings, belonging to the field of building repair technology. Background Technology

[0002] Cracks in a building's ceiling not only affect its aesthetics but can also threaten the building's structural safety and functionality. During building use, leaks from upstairs are a common cause of ceiling leaks. When upstairs pipes burst or the waterproofing layer fails, water seeps into the ceiling below, causing the ceiling material to become damp, soften, and even rot, ultimately forming leaks. Long-term leaks can lead to water stains and peeling on the downstairs ceiling, and in severe cases, holes. In the event of a fire, the high temperatures can cause the ceiling material to burn and deform, leading to structural damage and leaks. Even after a fire is extinguished, uneven heating can cause cracks and holes in the ceiling. Furthermore, buildings are subjected to various external impacts, such as falling heavy objects or human collisions. If the impact force is large enough to exceed the ceiling's bearing capacity, it can cause the ceiling to break, creating leaks.

[0003] For small holes, first sand the edges around the hole smooth. Then, cut a patch of paper or fiber material that matches the ceiling color to the appropriate size and glue it to the hole with special adhesive. Ensure the patch adheres tightly to the surrounding material without air bubbles. After the adhesive dries, paint the area with the same color as the ceiling to blend it seamlessly with the surrounding environment. For drywall ceilings, first clean away any loose plaster around the hole. Then, mix plaster powder and water to form a paste, fill the hole, and smooth the surface with a scraper. After the plaster dries, sand it smooth and then apply latex paint that matches the ceiling color.

[0004] For medium-sized leaks, although the leak area is relatively large, the surrounding ceiling material remains intact. First, accurately measure the size and shape of the leak with a ruler, then cut a panel of the same size from a ceiling panel of the same material. Carefully cut off the panel around the leak, taking care not to damage the surrounding joist structure. Install the newly cut panel in its original position, securing it with screws or special glue. Finally, fill and sand the joints, and apply paint matching the original ceiling. This repair process is a conventional method, but it is slow and the repair quality is difficult to standardize. For public buildings with different uses, some involving day and night use, the need for rapid repair and maintenance is higher. While expanding the universality of current repair methods requires more complex processing of the filler components, and custom-made fillers can save steps, their limitations in single-use are obvious, resulting in high costs and long production cycles. Currently, there are no universal filler replacement components that can save repair steps; in fact, the larger the leak area, the more difficult the repair becomes, especially since the edge connection between the leak edge and the newly cut panel is difficult to standardize, leading to secondary cracking and repair issues, failing to fundamentally solve the problem.

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0020] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 This embodiment describes a quick-connecting patching plate for repairing indoor ceilings in public buildings. It includes a top plate 1, at least two patching strips 2, two strip baffles 3, and at least one connecting strip 4. The at least two patching strips 2 are arranged horizontally side by side directly below the top plate 1. The top surface of each patching strip 2 is detachably bonded to the top plate 1. The two strip baffles 3 are integrally connected to both sides of the top plate 1. At least one connecting strip 4 is provided between the bottoms of the at least two patching strips 2. Each connecting strip 4 is detachably connected to the bottom of the at least two patching strips 2 in the same direction along the width of the patching strip 2.

[0021] In this embodiment, the connecting strip 4 serves to fill and level the surface, and also serves to connect multiple filler strips 2, thus playing a dual role of support and leveling the space.

[0022] This quick-connecting patch strip has a simple structure and is easy to assemble, saving the process of repairing gap 11. It can also ensure the flatness of the repaired ceiling with the original ceiling 10. It is especially suitable for the ceiling repair process of frequently used public buildings, which helps to standardize the repair operation process and ensure uniform repair quality.

[0023] In this embodiment, the top piece 1 is the main connecting piece of two interpolating strips 2 and strip baffles 3. Its own flexibility allows at least two interpolating strips 2 and two strip baffles 3 to enter the gap 11, so that the present invention can be arranged from above the original ceiling 10. With the support of the original ceiling 10, the present invention fills the gap 11 to achieve the repair effect.

[0024] In this embodiment, the original ceiling 10 is an existing plasterboard, sauna board, plywood or other board with a frame, and the gap 11 on the original ceiling 10 is a hole location caused by maintenance or other reasons.

[0025] In this embodiment, the top plate 1, at least two interpolating strips 2, two strip baffles 3, and at least one connecting strip 4 are all made of lightweight plastic or other lightweight and easily cut materials.

[0026] When at least two interlocking strips 2 are installed in the gaps 11 of the original ceiling 10, a leveling layer 7 is installed below the at least two interlocking strips 2.

[0027] This utility model can be made into various specifications. One of them is a quick self-connecting patch strip with a small area of ​​regular square or rectangle that does not require on-site cutting. It is used to fill gaps 11 in small and medium areas. When using it, first cut the hole on the original ceiling 10 to form a gap 11 with a regular shape that is consistent with the existing square or rectangle of this utility model. Then install this utility model in the gap 11.

[0028] Combination Figure 8As shown, another structural form of this utility model is a rectangular quick-connecting gap strip with a length between 2.5 and 4.5 meters, used to fill small and medium-sized gaps 11 or slender holes. In use, the holes on the original ceiling 10 are first cleaned and cut to form a regular rectangular gap 11. The size of this utility model is adjusted by removing at least two gap strips 2 that are connected by adhesive in the middle to complete the width reduction process. The length adaptation process is completed by cutting this utility model as a whole from the width direction. Finally, the utility model with the adjusted size is installed in the gap 11, and the relative positions of the remaining gap strips 2 are fixed by the connecting strip 4.

[0029] Other necessary operational steps, such as smoothing and surface treatment, involved in vulnerabilities not mentioned in this embodiment are consistent with the existing technology for repairing ceilings.

[0030] In this embodiment, the end corners of each supplementary strip 2 are chamfered and polished to facilitate collision when it rotates and opens and closes with the top plate 1.

[0031] In this embodiment, the filler strip 2 can be machined with scales along its length to indicate the size and position, making it convenient for operators to cut on-site.

[0032] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One or Two. In this implementation method, the top piece 1 is a flexible and rigid sheet or a rigid hinged sheet. When the top piece 1 is a flexible and rigid sheet, the top piece 1 is composed of a flexible fabric sheet 1-1 and two component pieces 1-2. The two component pieces 1-2 are arranged horizontally side by side and are connected to each other through the flexible fabric sheet 1-1. A strip baffle 3 is fixedly connected to the outside of each component piece 1-2. The lower side of the strip baffle 3 is the side that fits the original ceiling 10.

[0033] Furthermore, each component piece 1-2 is fixedly connected to its adjacent strip baffle 3 to form an integrated structure, thereby improving the simplification and compactness of the structure of this utility model.

[0034] In this embodiment, the flexible fabric piece 1-1 is a conventional building flexible fabric piece. The width of the flexible fabric piece 1-1 determines the number of detachable replacement strips 2. All detachable replacement strips 2 are arranged below the area where the flexible fabric piece 1-1 is located. Since the flexible fabric piece 1-1 and its corresponding replacement strip 2 are bonded together, it is easy to peel the replacement strip 2 from the flexible fabric piece 1-1. After the replacement strip 2 is peeled off, the flexible fabric piece 1-1 bends above the two component pieces 1-2. The size of the rectangular structure formed by the remaining replacement strips 2 is adapted to the notch 11 and is used to fill the notch 11.

[0035] In this embodiment, the filler strip 2 located below the component piece 1-2 is fixedly connected to the component piece 1-2.

[0036] In this embodiment, the working process of the top plate 1, which is in the form of a flexible and rigid sheet, in conjunction with at least two interpolating strips 2, two strip baffles 3, and at least one connecting strip 4 is as follows: Clean and cut the holes in the original ceiling 10 to form a regularly shaped gap 11. Based on the size of the gap 11, remove one or more interlocking strips 2 located below the flexible fabric 1-1, ensuring the width of the remaining interlocking strips 2 matches the width of the gap 11. Cut the length of this invention according to the length of the gap 11, ensuring the lengths match. Then, by bending the flexible fabric 1-1, insert at least two interlocking strips 2 and two strip-shaped baffles 3 into the gap 11. Place the two strip-shaped baffles 3 against the top surface of the original ceiling 10 on both sides of the gap 11, starting from above the original ceiling 10. This utility model is installed by connecting nails inserted between the strip baffle 3 and the original ceiling 10. Excess flexible fabric 1-1 is bent and pressed between or above the two component pieces 1-2. The flexible fabric 1-1 has adhesive properties, facilitating self-sealing and bonding. This further shortens the distance between the two component pieces 1-2 after use. The connecting strip 4 is then fixed to multiple interpolation strips 2 to complete the positioning process, thus completing the installation process and achieving a standardized and smooth repair of the gap 11. When the bottom surface of the interpolation strip 2 is concave to the bottom surface of the original ceiling 10, a leveling layer 7 can be applied to achieve a smooth surface. When the bottom surface of the interpolation strip 2 is at the same level as the bottom surface of the original ceiling 10, no leveling operation is required.

[0037] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 2. In this implementation method, the flexible fabric piece 1-1 is replaced with a hinge. The hinge is used to hinge between the two component pieces 1-2. With the cooperation of the hinge, the two component pieces 1-2 are in the maximum unfolding limit state and are in the same plane state, which is conducive to driving the patch strip 2 in a horizontal self-supporting state, forming a stable repair state at the repair site, which is convenient for the operator to control.

[0038] In this embodiment, the hinge is specifically selected from existing multi-angle adjustable hinges or large-angle buffer hinges. The minimum limit angle of the hinge is less than 180 degrees, with the optimal range being between 90 and 45 degrees. This facilitates the two component pieces 1-2 extending from the notch 11 into the original ceiling 10 at a relatively small opening angle. The maximum limit angle of the hinge is 180 degrees, ensuring that the device can unfold horizontally after being positioned above the original ceiling 10. The strip baffle 3 directly overlaps the two sides of the notch 11, achieving a self-connecting effect on both sides of the edge, eliminating the need for external equipment support during assembly.

[0039] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One, Two or Three. In this implementation method, at least two interpolation strips 2 are sequentially attached to form a self-removing interpolation main board 5. The self-removing interpolation main board 5 is sequentially and parallelly processed with multiple strip grooves 6 along its width direction. The strip grooves 6 are arranged in a one-to-one correspondence with the connecting strips 4. Each connecting strip 4 is set in its corresponding strip groove 6. The thickness of each connecting strip 4 is matched with the groove depth of the strip groove 6. The lower side of each connecting strip 4 is flush with the bottom surface of the self-removing interpolation main board 5.

[0040] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Method 1, 2, 3 or 4. In this implementation method, each connecting strip 4 is processed with a plurality of first connecting holes 8 along its length direction. Each connecting strip 4 is detachably connected to the self-disassembling replacement motherboard 5 through the plurality of first connecting holes 8.

[0041] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. In this implementation method, the length direction of the strip baffle 3 is the same as the length direction of the top piece 1, and the top side of each interpolating strip 2 is connected to the top piece 1 through an adhesive layer. The adhesive layer is an adhesive layer.

[0042] When the top piece 1 is a flexible and rigid sheet, it consists of a flexible fabric piece 1-1 and two component pieces 1-2. The flexible fabric piece 1-1 and the two component pieces 1-2 are aligned in length. The flexible fabric piece 1-1 is positioned between the two component pieces 1-2. Multiple support strips 2 are arranged side-by-side along the length of the component pieces 1-2 below the flexible fabric piece 1-1 and the two component pieces 1-2. The support strips 2 below the flexible fabric piece 1-1 are detachable. These support strips 2 are bonded to the flexible fabric piece 1-1 through an adhesive layer, making it easy to detach the support strips 2 from the flexible fabric piece 1-1. The reduction in the overall width of this invention is used to accommodate gaps 11 of different widths. The support strips 2 located below the component pieces 1-2 are fixedly connected to the component pieces 1-2 to enhance the overall structural support strength.

[0043] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four, Five or Six. In this implementation method, when the self-connecting repair part of the building's interior ceiling is set in the gap 11 of the original ceiling 10, the two sides of the self-removing and filling main board 5 are respectively attached to the inner walls of the two sides of the gap 11, and the two ends of the self-removing and filling main board 5 are respectively attached to the inner walls of the two ends of the gap 11.

[0044] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four, Five, Six or Seven. In this implementation method, after the present invention is installed, each strip baffle 3 is detachably connected to the original ceiling 10 by connecting nails.

[0045] In this embodiment, the strip baffle 3 can be machined with a second connecting hole along its length. When the edge of the strip baffle 3 near the notch 11 is close to the top surface of the original ceiling 10, the matching of the second connecting hole facilitates the connection nail to be inserted between the strip baffle 3 and the original ceiling 10.

[0046] This utility model achieves length and width adaptation and reduction to a predetermined size through the cooperation of the top plate 1, at least two interpolating strips 2, two strip baffles 3, and at least one connecting strip 4, which can be operated on the construction site.

[0047] The working principle of this utility model: Clean and cut the holes in the original ceiling 10 to form a regularly shaped notch 11. Measure the size of the notch 11 and adjust the size of this utility model to match the notch 11. The overall structural width is reduced by removing the interlocking strip 2. The length of this utility model is adapted by cutting the top piece 1, strip baffle 3, and interlocking strip 2 along the width direction of the interlocking strip 2. Finally, the adjusted utility model is installed in the notch 11. After the top piece 1 bends and moves upward, it moves the interlocking strip 2 and the two strip baffles 3 upward. The top piece 1 unfolds so that the two strip baffles 3 overlap on both sides of the notch 11 in the original ceiling 10. After fixing the relative positions of the remaining interlocking strips 2 and the two strip baffles 3 by the connecting strip 4, the utility model is installed. Finally, depending on the specific situation, a smoothing layer and sealant can be used to complete the entire repair process.
