Description

Technical Field

[0001] This utility model belongs to the field of building interior decoration technology, specifically referring to a prefabricated ceiling buckle structure with a reserved maintenance port. Background Technology

[0002] In the field of architectural decoration, prefabricated ceilings have been widely used in various architectural spaces due to their advantages such as high construction efficiency and high degree of industrialization. Their conventional structure mainly consists of a keel frame fixed to the building ceiling via suspension rod assemblies, and ceiling panels that are movably installed within this frame. In such ceiling systems, how to achieve an efficient, reliable, and easy-to-maintain connection between the ceiling panels and the keel has always been a focus of attention for those skilled in the art. Although prefabricated ceilings on the market have achieved modular design, some pain points still exist in practical applications, severely restricting construction efficiency and subsequent maintenance experience. These are specifically manifested as follows: 1. The installation process is cumbersome, relies on tools, and has low security. Traditional prefabricated ceiling panels are often connected to the keel using bolts, spring clips, or adhesive. Bolt fixing requires suspending the panel above the keel, manually aligning the bolt holes, and then using tools such as screwdrivers to lock it in place. This method involves many steps and the panel is prone to falling due to imbalance during the suspension process, posing a construction safety risk. While spring clips do not require bolts, the spring clips need to be manually pried open and inserted into the edge of the panel. In narrow spaces, the spring clips are prone to falling off or not being installed properly, still requiring auxiliary tools for adjustment, thus failing to achieve true tool-free assembly.

[0003] 2. Difficult to disassemble and maintain, easily causing structural damage. When ceilings need maintenance (such as water and electricity pipeline repairs, ventilation equipment maintenance), the existing structure has two major defects: bolt-fixed ceilings require the bolts to be removed one by one, and some bolts are prone to rust and jamming after long-term use. Disassembly requires forceful prying, which can cause damage to the edges of the panels or deformation of the keel; spring-loaded ceilings do not have a clear unlocking structure, and disassembly requires inserting a pry bar from the edge of the panel to forcibly separate it, which can easily damage the elasticity of the spring or scratch the surface of the panel. Utility Model Content

[0004] To address the aforementioned problems of cumbersome ceiling panel installation process, reliance on tools, low safety, and difficulties in disassembly and maintenance that can easily cause structural damage, this utility model provides a prefabricated ceiling snap-on structure with a reserved inspection port.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a prefabricated ceiling buckle structure with reserved maintenance opening, including a ceiling keel frame, several ceiling panels, a buckle mechanism and a maintenance panel. The ceiling keel frame is composed of a main keel and a secondary keel that are perpendicularly connected to each other. The main keel is fixed to the building roof by a hanger assembly. The ceiling panel is a rectangular plate that is movably installed within a frame formed by the main keel and the secondary keel. The buckling mechanism includes an elastic snap-fit ​​component provided on the secondary keel, and snap-fit ​​grooves symmetrically opened on both sides of the ceiling panel. The elastic snap-fit ​​component snaps into the snap-fit ​​groove through elastic deformation; The access panel is installed in the same manner within a frame at a specific location.

[0006] Furthermore, multiple sets of the elastic snap-fit ​​connectors are symmetrically arranged along both sides of the secondary keel; Each set of elastic snap-fit ​​components includes a horizontal groove formed on the secondary keel, a spring horizontally installed in the horizontal groove, and a snap-fit ​​block movably installed in the horizontal groove; One end of the spring is fixed to the inner wall of the transverse groove, and the other end is fixed to the side of the locking block; The card block's locking end is movably inserted into the locking slot.

[0007] Furthermore, the card block is provided with an inclined portion; A lever is fixed to the bottom of the card block.

[0008] Furthermore, a horizontal through groove is provided at the bottom end of the secondary keel, and the through groove is connected to the transverse groove; The lever is horizontally movable within the through groove, with its bottom extending outside the through groove; The secondary keel has multiple sets of vertical grooves, located on both sides of each set of horizontal grooves.

[0009] Furthermore, the two sides of the ceiling panel are secured by corresponding elastic snap-fit ​​components on adjacent secondary keels; Auxiliary blocks are fixed to both sides of the ceiling panel; The auxiliary blocks are located on both sides of the snap-fit ​​groove and can be inserted into the vertical groove of the secondary keel.

[0010] Furthermore, an inverted T-shaped groove is provided at the top of the secondary keel; Multiple sets of sleeve blocks are evenly fitted on the main keel, and a slider that slides in conjunction with an inverted T-shaped groove is fixed at the bottom of each sleeve block.

[0011] Furthermore, the edge structure of the inspection panel is consistent with that of the ceiling panel, and the center of the panel is marked with the words "Inspection Panel".

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure: 1. This utility model achieves truly tool-free, high-efficiency assembly and disassembly of ceiling panels through the coordinated operation of a snap-fit ​​mechanism, a lever, and an auxiliary block. Specifically, this solution adopts an installation method of "first inserting the frame, then pressing down on the panel," abandoning the traditional installation method of lifting the panel upwards and aligning it with the keel. The traditional upward lifting method requires bolt fixing, which is time-consuming, labor-intensive, and increases the risk. In this solution, the inclined part on the snap-fit ​​block forms a guide slope, which automatically converts the downward pressure of the panel into the lateral contraction force of the snap-fit ​​block during installation, guiding the panel to be accurately positioned; when the snap-fit ​​groove is aligned with the snap-fit ​​block, the spring return force pushes the snap-fit ​​block into the groove, achieving self-locking. The entire process is completed in one step, requiring no tools, and both hands are always under the panel for safe force application, significantly reducing the difficulty and time of operation, and improving construction safety and efficiency.

[0013] 2. Clear and precise operation interface for easy and effortless disassembly: The lever, fixed to the bottom of the locking block, extends to the outside of the secondary keel groove, forming a clear and direct manual operation interface. During disassembly, simply press the lever inward to precisely drive the locking block out of the locking groove, making assembly and disassembly convenient. This design avoids direct force on the panel surface, effectively preventing potential damage to the panel or keel in traditional disassembly methods. It is particularly convenient for repeatedly opening and closing the inspection port, greatly improving the ease of maintenance. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-7As shown, this utility model provides a prefabricated ceiling snap-fit ​​structure with a reserved maintenance opening, including a ceiling keel frame 1, several ceiling panels 2, a snap-fit ​​mechanism 3, and a maintenance panel 4. The ceiling keel frame 1 is composed of a main keel 11 and a secondary keel 12 that are perpendicularly connected to each other. The main keel 11 is fixed to the building roof by a hanger assembly 14. The top of the secondary keel 12 is provided with an inverted T-shaped groove 123. Multiple sets of sleeve blocks 111 are evenly fitted on the main keel 11. The bottom of the sleeve block 111 is fixed with a slider 112 that slides in cooperation with the inverted T-shaped groove 123, realizing a quick and flexible connection between the secondary keel 12 and the main keel 11. The ceiling keel frame 1 constitutes the basic load-bearing skeleton of the ceiling system. Through the vertical cross connection of the main keel 11 and the secondary keel 12, a stable and uniformly stressed grid support system is formed, providing a foundation for the modular installation of the ceiling panels 2. The ceiling panel 2 is a rectangular panel that is movably installed within a frame 13 formed by the main keel 11 and the secondary keel 12. The standardized rectangular panel facilitates mass production and rapid installation. Its movable installation within the frame 13 achieves a balance between the overall flatness of the ceiling and the replaceability of individual panels. The snap-fit ​​mechanism 3 includes an elastic snap-fit ​​member 31 disposed on the secondary keel 12 and snap-fit ​​grooves 32 symmetrically opened on both sides of the ceiling panel 2. The elastic snap-fit ​​member 31 snaps into the snap-fit ​​groove 32 through elastic deformation, thereby realizing the fixed connection between the ceiling panel 2 and the secondary keel 12. By applying external force to make the elastic snap-fit ​​member 31 disengage from the snap-fit ​​groove 32, the ceiling panel 2 can be easily disassembled, realizing tool-free quick snap-fit ​​fixing and disassembly of the panel, which greatly improves the installation and disassembly efficiency. The inspection panel 4 is installed in the same way within the frame 13 at a specific location; the edge structure of the inspection panel 4 is consistent with that of the ceiling panel 2, and the center of the panel is marked with the words "Inspection Panel 4" to facilitate maintenance personnel to quickly locate the inspection port, avoid accidentally disassembling ordinary panels, improve maintenance efficiency and safety, maintain the overall appearance of the ceiling, and ensure the accessibility of the maintenance passage.

[0020] like Figure 1-7As shown, multiple sets of elastic snap-fit ​​members 31 are symmetrically arranged along both sides of the secondary keel 12; each set of elastic snap-fit ​​members 31 includes a transverse groove 311 opened on the secondary keel 12, a spring 312 horizontally installed in the transverse groove 311, and a snap-fit ​​block 313 movably installed in the transverse groove 311; one end of the spring 312 is fixed to the inner wall of the transverse groove 311, and the other end is fixed to the side of the snap-fit ​​block 313; the snap-fit ​​end of the snap-fit ​​block 313 is movably inserted into the snap-fit ​​groove 32; the snap-fit ​​block 313 is provided with an inclined part, which... The inclined part forms a guide slope. When the ceiling panel 2 is installed, the lower edge of the ceiling panel 2 will first contact this inclined part. As the ceiling panel 2 continues to move downward, the inclined part converts the vertical downward movement of the panel into the horizontal inward displacement of the locking block 313, thereby compressing the spring 312 and realizing the automatic alignment and tool-free locking of the panel. The bottom of the locking block 313 is fixed with a lever 314, which serves as a direct manual operation interface and provides a clear force application point for disassembling the panel. During installation of the ceiling panel 2, as the panel moves downwards, its edge presses against the inclined portion of the locking block 313, causing it to overcome the spring force of the spring 312 and move inwards towards the horizontal groove 311. The spring 312 is then compressed. When the locking groove 32 on the panel aligns with the locking block 313, the spring 312 loses its external pressure and, under its own restoring force, pushes the locking block 313 outwards. The locking end of the locking block 313 then inserts into the locking groove 32, thus firmly fixing the ceiling panel 2 to the secondary keel 12. During disassembly, pressing the lever 314 moves the locking block 313 inwards towards the horizontal groove 311, compressing the spring 312 again. The locking end of the locking block 313 disengages from the locking groove 32, releasing the ceiling panel 2 from its fixation. After the ceiling panel 2 is removed, the spring 312 returns to its initial extended state, preparing the panel 313 for the next installation. The entire process requires no additional tools; automatic locking and easy unlocking are achieved solely through the elastic change of spring 312, ensuring a stable connection and convenient operation.

[0021] like Figure 2 , 3 As shown in Figure 6, a horizontal through groove 121 is provided at the bottom of the secondary keel 12, which is connected to the horizontal groove 311. The lever 314 is horizontally movable in the through groove 121 and extends out of the through groove 121. When disassembling, by driving the lever 314 to move, the locking block 313 can be directly driven to overcome the force of the spring 312 to move horizontally, so that it can accurately and reliably disengage from the locking groove 32 of the ceiling panel 2, thereby releasing the horizontal locking. Multiple sets of vertical grooves 122 are vertically provided on the secondary keel 12, which are located on both sides of each set of horizontal grooves 311.

[0022] like Figure 7As shown, the two side edges of the ceiling panel 2 are secured by corresponding elastic snap-fit ​​pieces 31 on adjacent secondary keels 12; auxiliary blocks 21 are fixed to the two side edges of the ceiling panel 2. Before final locking using the snap-fit ​​mechanism 3, the auxiliary blocks 21 are inserted into the vertical grooves 122 to pre-position the ceiling panel 2 precisely. This mechanism effectively prevents the panel from shaking and misaligning before final locking, ensuring that the snap-fit ​​pieces 313 can be accurately aligned and snapped into the snap-fit ​​grooves 32 of the panel; the auxiliary blocks 21 are located on both sides of the snap-fit ​​grooves 32 and can be inserted into the vertical grooves 122 of the secondary keels 12.

[0023] In practical use 1. Installation of the keel frame 13 First, the main keel 11 is fixed to the building roof at the designed spacing using the hanger assembly 14. Then, the inverted T-shaped groove 123 at the top of the secondary keel 12 is aligned with the slider 112 of the upper sleeve block 111 of the main keel 11, and the secondary keel 12 is slid to the predetermined position so that it intersects the main keel 11 perpendicularly and forms a stable grid frame 13.

[0024] 2. Installation of ceiling panel 2 During installation, if there is sufficient space in the frame 13, the ceiling panel 2 can be directly extended vertically into the frame 13 enclosed by the main keel 11 and the secondary keel 12; if the length of the frame 13 cannot meet the requirement for the overall vertical installation of the ceiling panel 2, the ceiling panel 2 is tilted so that the ceiling panel 2 is gradually extended into the frame 13 along the diagonal direction until the panel is completely inserted into the space between the building top surface and the frame 13. After the panel enters the installation space, slowly adjust the panel to a horizontal position. Hold the bottom edge of the panel with both hands and gently pull it downwards. At the same time, observe and adjust the position of the panel so that the auxiliary blocks 21 on both sides of the panel are initially aligned with the vertical grooves 122 on the corresponding secondary keel 12, completing the pre-positioning. Continue to pull the panel downwards. The bottom of the panel will first contact the locking block 313 on the secondary keel 12 and press it. At this time, the locking block 313 moves inwards along the horizontal groove 311 under the action of external force, and the spring 312 in the horizontal groove 311 is compressed. As the panel continues to move downwards, when the locking grooves 32 on both sides of the panel are aligned with the locking block 313, the spring 312 pushes the locking block 313 outwards under the action of the restoring force. The locking block 313 automatically inserts into the locking groove 32. At this point, the ceiling panel 2 is stably locked onto the secondary keel 12, and the installation is completed.

[0025] 3. Installation of access panel 4 The installation steps for the access panel 4 are exactly the same as those for the ordinary ceiling panel 2. Its edge structure, auxiliary block 21, and snap-fit ​​groove 32 are identical, ensuring a consistent connection method. During installation, simply place it at the pre-planned access point and follow the panel installation method described above. The center of the panel is marked with the words "Access Panel 4" for easy identification in the future.

[0026] 4. Disassembly procedure (applicable to ceiling panel 2 and access panel 4) During disassembly, hold the levers 314 at the bottom of the corresponding secondary keel 12 on both sides of the panel with both hands and manually push them outward away from the panel. The levers 314 move horizontally along the horizontal through groove 121 of the secondary keel 12, simultaneously moving the locking block 313 inward into the horizontal groove 311. The spring 312 in the horizontal groove 311 is compressed again, and the locking block 313 disengages from the locking groove 32 of the panel, releasing the horizontal locking fixation of the panel. Then, hold the bottom edge of the panel with both hands and gently push upward, so that the auxiliary blocks 21 on both sides of the panel gradually disengage from the vertical groove 122 of the secondary keel 12. After the auxiliary blocks 21 are completely disengaged from the vertical groove 122, choose the removal method according to the space of the frame 13: if there is enough space, the panel can be kept horizontal and removed directly upward; if space is limited, tilt the panel to one side and move it out gradually along the diagonal direction of the frame 13 until the panel is completely removed from the frame 13, and the disassembly is complete.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
