Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a quick-installation ceiling for building decoration and its assembly method. Background Technology

[0002] In the field of building decoration, ceiling installation is one of the key aspects of interior design. Ceilings not only serve a decorative purpose but also conceal pipes, equipment, and other structural elements on the building's ceiling, enhancing both the aesthetics and practicality of the interior space.

[0003] A search revealed that Chinese patent publication number CN119145570A discloses a quick-installation ceiling for building decoration and its assembly method. While this technical solution can shorten ceiling assembly time, reduce operational difficulty, and improve assembly efficiency, and provides a firm and reliable assembly that effectively ensures safety after assembly, traditional ceiling installation typically involves on-site assembly. Construction workers must operate within the building's ceiling space to install components such as the main keel, secondary keel, and ceiling panels. This installation method has the following main problems:

[0004] When installing ceiling panels, the keel must first be fixed to the top of the building. Then, the ceiling panels are installed one by one onto the keel. Each ceiling panel needs to be fixed with multiple screws or rivets, which not only increases installation time but also easily leads to loose connections due to improper operation. After traditional ceiling installation, if maintenance or replacement of parts is needed, the disassembly process is very cumbersome. Due to the large number of connection points, each screw or rivet needs to be loosened during disassembly, which is not only time-consuming and labor-intensive but also easily damages the ceiling panels and keel.

[0005] In summary, traditional ceiling installation methods have many shortcomings in terms of construction efficiency, installation stability, operational difficulty, and maintenance convenience. Therefore, there is a need for a new type of quick-installation ceiling for building decoration and its assembly method, which can overcome the shortcomings of existing technologies and achieve efficient, fast, stable, and easy-to-maintain ceiling installation. Summary of the Invention

[0006] One of the objectives of this application is to solve the problems of difficult disassembly and maintenance, complex connection points and easily damaged parts after traditional ceiling installation, which affect stability, and to provide a quick-installation ceiling for building decoration and its assembly method.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: a quick-installation ceiling for building decoration and its assembly method, comprising: a steel beam, a fixing component, a connecting component, and a pressing component. The fixing component is provided at the bottom of the steel beam and is distributed on both sides of the bottom of the steel beam. The fixing component is used to connect the steel beam. The number of fixing components is at least four. One end of the bottom of the connecting component is connected to the main keel. An adjusting component is provided at the bottom of the main keel. A secondary keel is provided below the adjusting component. The main keel is connected to the secondary keel through the adjusting component. The secondary keel and the main keel are distributed at a perpendicular angle to each other. A pressing component is provided at the bottom of the secondary keel. The pressing component is fixedly installed on the surface of the ceiling panel. Multiple ceiling panels are provided, and the ceiling panels are tightly fitted together.

[0008] Preferably, the fixing component includes a first connecting block, one end of which has a slot, and the top and bottom surfaces of the slot are provided with a first fixing nut. Both ends of the first connecting block have slots, and the slots at both ends of the first connecting block are threadedly connected to positioning bolts.

[0009] One end of the positioning bolt is embedded inside the positioning plate, which is rotatably connected to the first connecting block via a connecting shaft. Multiple circular grooves are provided on one side surface of the positioning plate, arranged in a ring-shaped, equidistant pattern. By incorporating the first connecting block, positioning bolt, positioning plate, and connecting shaft, the fixing assembly can achieve flexible rotation and angle adjustment. This design allows for rapid adjustment during installation based on the actual angle and position of the steel beam, ensuring the suspension rods remain vertical, thereby improving the flexibility and adaptability of ceiling installation. Simultaneously, the cooperation between the positioning bolt and the positioning plate effectively fixes the adjusted angle, ensuring installation stability and reliability, further enhancing the overall performance and quality of the ceiling system.

[0010] Preferably, a clamp is provided on one side of the positioning plate. The clamp is welded to one side of the positioning plate, and one end of the clamp is provided with a U-shaped groove. A first fastening bolt is provided at the bottom of one end of the clamp. The first fastening bolt is threadedly connected to the inside of the clamp and fits tightly against the surface of the steel beam. By providing a clamp and a first fastening bolt on one side of the positioning plate, the fixing component can achieve a tight and stable connection with the steel beam. The U-shaped groove design of the clamp can adapt to the shape of the steel beam, ensuring its fit with the steel beam. The threaded connection of the first fastening bolt provides reliable fixing force, allowing the fixing component to be firmly attached to the surface of the steel beam during installation. Even if there is an angular deviation or unevenness in the steel beam, the stability and reliability of the connection can be ensured by adjusting the angle of the positioning plate. This design not only improves the flexibility and adaptability of ceiling installation, but also enhances the overall stability and safety of the ceiling system, effectively avoiding loosening or falling off due to insecure fixing.

[0011] Preferably, the connecting assembly includes a suspension rod, one top end of which is inserted into the first connecting block and threadedly connected to a first fixing nut. The bottom end of the suspension rod is welded to a second connecting block. A slot is formed at the bottom of the second connecting block, which is connected to a third connecting block via a second fastening bolt. The bottom of the third connecting block is welded to the top of a fixing bolt. The fixing bolt is inserted into a slot on the surface of the main keel and threadedly connected to a second fixing nut. Through the combination of these multiple components, the connecting assembly can firmly connect the steel beam and the main keel, ensuring the structural stability of the ceiling. The threaded connection between the suspension rod and the positioning bolt, as well as the cooperation between the fixing bolt and the main keel, provides reliable fixing force, enabling the ceiling to withstand a certain weight and external force after installation without easily loosening or falling off. Simultaneously, this connection method facilitates installation and disassembly, improving construction efficiency and the maintainability of the ceiling system.

[0012] Preferably, the adjusting component includes a connecting rod. One top end of the connecting rod is inserted into the main keel, and the top end of the connecting rod is threaded and threadedly connected to a third fixing nut. The bottom end of the connecting rod is fixedly connected to a groove at the top of a slot, and the bottom of the slot has a bottom groove that engages with the surfaces of both sides of the secondary keel. By setting up the adjusting component, especially the connection method between the connecting rod and the main and secondary keels, flexible adjustment and stable connection between the main and secondary keels are achieved. The threaded design at the top of the connecting rod and the cooperation of the third fixing nut ensure that the connecting rod is firmly fixed inside the main keel, ensuring connection stability. Simultaneously, the engagement of the groove at the bottom of the connecting rod with the secondary keel not only enables quick installation but also allows adjustment of the secondary keel's position as needed, enhancing the overall adaptability and flexibility of the ceiling system. This ensures the stability and reliability of the ceiling during use, effectively avoiding loosening or deformation caused by insecure connections, and improving the overall performance and service life of the ceiling system.

[0013] Preferably, the pressing assembly includes a lower guide block, the bottom of which is connected to the top of the ceiling panel via a third fastening bolt. An upper guide block is positioned on top of the lower guide block, and a fixing rod is provided between the upper and lower guide blocks. One end of the fixing rod is welded to the lower and upper guide blocks, respectively. The upper guide block has a groove inside, and a telescopic column is installed inside the groove. A locking block is welded to the top end of the telescopic column. By configuring the pressing assembly, particularly the combined structure of the lower guide block, upper guide block, fixing rod, telescopic column, and locking block, the ceiling panel is suspended. The quick and secure connection between the ceiling panel and the secondary keel makes the installation process of the ceiling panel simpler and faster. The connection between the ceiling panel and the secondary keel can be completed simply by pressing, without complicated tools or cumbersome steps. At the same time, the cooperation of the telescopic column and the locking block can provide reliable fixing force, ensuring the stability of the ceiling panel during use and effectively avoiding loosening or falling off due to insecure connection. In addition, the design of this pressing component is also easy to disassemble and maintain, further improving the practicality and economy of the ceiling system and reducing maintenance costs and time.

[0014] Preferably, the bottom of the upper guide block and the top of the lower guide block are provided with ratchet teeth, and the ratchet teeth on the bottom of the upper guide block and the top of the lower guide block face opposite directions. The surface of the ratchet teeth is provided with four grooves. A limit block is provided between the upper and lower guide blocks. The limit block is welded to the outer wall surface of the telescopic column, and four limit blocks are provided, evenly spaced. The limit blocks slide in contact with the surfaces of the upper and lower guide blocks. By providing mutually cooperating ratchet teeth between the upper and lower guide blocks and limit blocks welded to the outer wall of the telescopic column, a unique self-locking and limiting mechanism is formed. The design enables the pressing component to automatically position and fix itself during installation, ensuring a more secure and stable connection between the ceiling panel and the secondary keel. When the ceiling panel is pressed, the telescopic column slides within the upper guide block, and the limiting block rotates under the action of the ratchet, thereby achieving the engagement of the locking block with the groove at the bottom of the secondary keel. This self-locking mechanism not only improves installation efficiency but also ensures the stability of the ceiling panel during use, effectively preventing loosening or detachment caused by external forces. At the same time, the equidistant distribution and sliding contact design of the limiting blocks further enhance the reliability and durability of the pressing component, extending the service life of the ceiling system.

[0015] Preferably, the telescopic column slides in contact with the inner wall of the upper guide block, a spring is fitted on the outside of one top end of the telescopic column, and an annular protrusion is provided at one top end of the telescopic column. The top locking block of the telescopic column engages with the bottom groove of the secondary keel through rotational engagement. Through the sliding contact design between the telescopic column and the upper guide block, as well as the spring and locking block structure at the top of the telescopic column, a quick and reliable connection and convenient disassembly between the ceiling panel and the secondary keel are achieved. The elasticity of the spring allows the telescopic column to generate appropriate displacement during the pressing process, thereby driving the locking block to engage or disengage with the groove at the bottom of the secondary keel. This design not only improves the efficiency of ceiling panel installation and disassembly, but also enhances the stability and reliability of the ceiling system.

[0016] Preferably, the steps are as follows:

[0017] S01. Install the fixing components on both sides of the building steel beam. By clamping the groove on one side of the clamp onto both sides of the steel beam, and then tightening the first fastening bolt, one end of the first fastening bolt can abut against the surface of the steel beam, so that the clamp can be fixedly connected to the steel beam. When the steel beam is at an angle, by loosening the positioning bolt, one end of the positioning bolt can be moved out of the positioning plate groove, so that the first connecting block can be rotated, so that the suspension rod can be kept in a vertical state. Then tighten the positioning bolt, so that one end of the positioning bolt can be inserted into the groove of the positioning plate, so that the angle of the suspension rod can be fixed.

[0018] S02. Then, insert the fixing bolt at one end of the bottom of the suspension rod into the hole groove on the surface of the main keel, connect the main keel to the fixing bolt through the second fixing nut, then insert the connecting rod into the groove on the surface of the main keel, connect the connecting rod to the main keel through the third fixing nut, and then engage the slot at the bottom of the connecting rod with the secondary keel, so that the main keel and the secondary keel can be installed quickly.

[0019] S03. By aligning and inserting the locking block of the pressing component at the top of the ceiling panel with the groove at the bottom of the secondary keel, pressing the ceiling panel causes the telescopic column to slide inside the upper guide block when the pressing component is compressed. The ratchet on the surface of the lower guide block contacts the limiting block. The slope of the ratchet on the surface of the lower guide block forces the limiting block to rotate 45 degrees around the axis of the telescopic column. When the pressure on the ceiling panel is released, the telescopic column moves upward inside the upper guide block under the push of the spring. The telescopic column can then drive the limiting block to contact the ratchet at the bottom of the upper guide block. The slope of the ratchet on the upper guide block forces the limiting block to continue rotating 45 degrees around the axis of the telescopic column. This allows the limiting block to drive the locking block to rotate 90 degrees through the telescopic column, so that both ends of the locking block can engage with the groove at the bottom of the secondary keel. Thus, pressing the pressing component allows the ceiling panel to be quickly connected to the secondary keel, greatly improving installation efficiency. Conversely, pressing the ceiling panel allows it to be disassembled.

[0020] Compared with the prior art, the beneficial effects of this application are as follows:

[0021] Significantly Improved Installation Efficiency: This solution greatly simplifies installation steps by optimizing the ceiling assembly structure and method. The design of the connecting and pressing components allows for faster connection between the main keel, secondary keel, and ceiling panels. The locking blocks of the pressing components engage with the grooves at the bottom of the secondary keel, allowing for simple pressing operations to complete the installation of the ceiling panels without the need for complex screw fixings or other tools, significantly reducing installation time. Simultaneously, the flexible design of the fixing and connecting components allows for rapid adjustments during installation to adapt to steel beams at different angles and positions, ensuring the suspension rods remain vertical, further improving installation flexibility and efficiency. The optimized overall assembly process avoids cumbersome steps and repetitive operations in traditional installation methods, making ceiling installation more efficient, significantly shortening the construction cycle, and reducing labor costs.

[0022] Enhanced installation firmness and stability: The telescopic column and locking block design in the pressing assembly, through the elasticity of the spring and the limiting action of the ratchet, achieves rapid fixing and stable support of the ceiling panel. During installation, when the pressing assembly is squeezed, the telescopic column slides inside the upper guide block, and the ratchet on the surface of the lower guide block contacts the limiting block, forcing the limiting block to rotate around the axis of the telescopic column, thereby driving the locking block to rotate and engage in the groove at the bottom of the secondary keel. This structural design not only ensures the rapid installation of the ceiling panel, but also provides additional stability and vibration resistance through the elasticity of the spring and the limiting action of the ratchet, effectively avoiding the loosening and deformation problems that may occur in traditional installation methods, and improving the overall stability and service life of the ceiling.

[0023] Easy disassembly and maintenance: The push-button component design of this solution is not only easy to install but also easy to disassemble. The ceiling panel can be separated from the secondary keel with a simple press operation, without complicated tools and steps, which greatly reduces maintenance costs and time. This disassembly makes ceiling maintenance and component replacement more convenient, improving the practicality and economy of the ceiling system. When it is necessary to replace a damaged ceiling panel or perform other maintenance work, the construction personnel can easily remove the ceiling panel from the secondary keel for replacement or repair simply by pressing it. This design not only facilitates daily maintenance but also reduces the impact of maintenance work on the building decoration, further improving the overall performance of the ceiling system and the user experience.

The design of the telescopic column 706 and the locking block 708 in the pressing assembly 7 allows for... The elastic force of spring 707 and the limiting effect of ratchet enable the rapid fixing and stable support of ceiling panel 8. During installation, when pressing component 7 is squeezed, telescopic column 706 slides inside upper guide block 704, and ratchet on the surface of lower guide block 701 contacts limiting block 705, forcing limiting block 705 to rotate around the axis of telescopic column 706, thereby driving the locking block 708 to rotate and engage in the groove at the bottom of secondary keel 6. This structural design not only ensures the rapid installation of ceiling panel 8, but also provides additional stability and vibration resistance through the elastic force of spring 707 and the limiting effect of ratchet, effectively avoiding the loosening and deformation problems that may occur in traditional installation methods, and improving the overall stability and service life of the ceiling.

[0039] Example 2:

[0040] One preferred embodiment of this application, such as Figures 1 to 9As shown, a quick-install ceiling for building decoration and its assembly method are disclosed. The fixing component 2 includes a first connecting block 201. One end of the first connecting block 201 has a slot, and the top and bottom surfaces of the slot are provided with first fixing nuts 202. Both ends of the first connecting block 201 have slots, and the slots at both ends of the first connecting block 201 are threadedly connected to positioning bolts 203. One end of the positioning bolt 203 is embedded inside a positioning disc 205. The positioning disc 205 is rotatably connected to the first connecting block 201 via a connecting shaft 204. One side surface of the positioning disc 205 has multiple circular grooves, which are distributed in an annular, equidistant pattern. A clamp 206 is provided on one side of the positioning disc 205, and the clamp 206 is connected to the positioning disc 205. 05 is welded on one side, and a U-shaped groove is provided at one end of the caliper 206.

One end of 07 can abut against the surface of the steel beam 1, allowing the clamp 206 to be fixedly connected to the steel beam 1. When the steel beam 1 is at an angle, by loosening the positioning bolt 203, one end of the positioning bolt 203 can be moved out of the groove of the positioning plate 205, thereby allowing the first connecting block 201 to rotate, so that the suspension rod 301 can remain in a vertical state. Then, by tightening the positioning bolt 203, one end of the positioning bolt 203 can be inserted into the groove of the positioning plate 205, so that the angle of the suspension rod 301 can be fixed.

[0041] Example 3:

[0042] A method for assembling a quick-installation suspended ceiling for building decoration, comprising the following steps:

[0043] S01. Install the fixing component 2 on both sides of the building steel beam 1. By clamping the groove on one side of the clamp 206 onto both sides of the steel beam 1, and then tightening the first fastening bolt 207, one end of the first fastening bolt 207 can abut against the surface of the steel beam 1, so that the clamp 206 can be fixedly connected to the steel beam 1. When the steel beam 1 has an angle, by loosening the positioning bolt 203, one end of the positioning bolt 203 can be moved out of the groove of the positioning plate 205, so that the first connecting block 201 can rotate, so that the suspension rod 301 can be kept in a vertical state. Then tighten the positioning bolt 203, so that one end of the positioning bolt 203 can be inserted into the groove of the positioning plate 205, so that the angle of the suspension rod 301 can be fixed.

[0044] S02. Then, the fixing bolt 305 at one end of the bottom of the suspension rod 301 is inserted into the hole groove on the surface of the main keel 4, and the main keel 4 is connected to the fixing bolt 305 by the second fixing nut 306. Then, the connecting rod 501 is inserted into the groove on the surface of the main keel 4, and the connecting rod 501 is connected to the main keel 4 by the third fixing nut 502. Then, the slot 503 at the bottom of the connecting rod 501 is engaged with the secondary keel 6, so that the main keel 4 and the secondary keel 6 can be installed quickly.

[0045] S03. By aligning and inserting the locking block 708 of the pressing component 7 at the top of the ceiling panel 8 with the groove at the bottom of the secondary keel 6, the ceiling panel 8 is pressed. When the pressing component 7 is compressed, the telescopic column 706 slides inside the upper guide block 704, and the ratchet on the surface of the lower guide block 701 contacts the limiting block 705. The slope of the ratchet on the surface of the lower guide block 701 forces the limiting block 705 to rotate forty-five degrees around the axis of the telescopic column 706. When the pressure on the ceiling panel 8 is released, the telescopic column 706 moves upward inside the upper guide block 704 under the push of the spring 707. Then, the telescopic column 706 can drive the limiting block 705 to contact the bottom ratchet of the upper guide block 704. The slope of the ratchet of the upper guide block 704 can force the limiting block 705 to continue to rotate 45 degrees around the axis of the telescopic column 706. This allows the limiting block 705 to drive the locking block 708 to rotate 90 degrees through the telescopic column 706, so that both ends of the locking block 708 can engage with the groove at the bottom of the secondary keel 6. Thus, by pressing the pressing component 7, the ceiling panel 8 can be quickly connected to the secondary keel 6, greatly improving the installation efficiency. Conversely, by pressing the ceiling panel 8, it can be disassembled.

6. The assembly method of a quick-installation suspended ceiling for building decoration as described in claim 5, characterized in that, The steps are as follows: S01. Install the fixing component (2) on both sides of the building steel beam (1). By clamping the groove on one side of the clamp (206) onto both sides of the steel beam (1), and then tightening the first fastening bolt (207), one end of the first fastening bolt (207) can abut against the surface of the steel beam (1), so that the clamp (206) can be fixedly connected to the steel beam (1). When the steel beam (1) has an angle, by loosening the positioning bolt (203), one end of the positioning bolt (203) can be moved out of the groove of the positioning plate (205), so that the first connecting block (201) can be rotated, so that the suspension rod (301) can be kept vertical. Then tighten the positioning bolt (203), so that one end of the positioning bolt (203) can be inserted into the groove of the positioning plate (205), so that the angle of the suspension rod (301) can be fixed. S02. Then, insert the fixing bolt (305) at one end of the bottom of the suspension rod (301) into the hole groove on the surface of the main keel (4), and connect the main keel (4) with the fixing bolt (305) through the second fixing nut (306). Then, insert the connecting rod (501) into the groove on the surface of the main keel (4), and connect the connecting rod (501) with the main keel (4) through the third fixing nut (502). Then, engage the slot (503) at the bottom of the connecting rod (501) with the secondary keel (6), so that the main keel (4) and the secondary keel (6) can be installed quickly. S03. By aligning and inserting the locking block (708) of the pressing assembly (7) at the top of the ceiling panel (8) with the groove at the bottom of the secondary keel (6), the ceiling panel (8) is pressed. When the pressing assembly (7) is squeezed, the telescopic column (706) slides inside the upper guide block (704), and the ratchet on the surface of the lower guide block (701) contacts the limiting block (705). The slope of the ratchet on the surface of the lower guide block (701) forces the limiting block (705) to rotate forty-five degrees around the axis of the telescopic column (706). When the pressing on the ceiling panel (8) is released, the telescopic column (706) moves upward inside the upper guide block (704) under the push of the spring (707). The telescopic column (706) moves, and the telescopic column (706) can drive the limiting block (705) to contact the ratchet at the bottom of the upper guide block (704). The slope of the ratchet of the upper guide block (704) can force the limiting block (705) to continue to rotate 45 degrees around the axis of the telescopic column (706). This allows the limiting block (705) to drive the locking block (708) to rotate 90 degrees through the telescopic column (706). This allows the two ends of the locking block (708) to engage with the groove at the bottom of the secondary keel (6). Thus, by pressing the pressing component (7), the ceiling panel (8) can be quickly connected to the secondary keel (6), greatly improving the installation efficiency. Conversely, by pressing the ceiling panel (8), it can be disassembled.
