Description

Technical Field

[0001] This invention belongs to the field of keel structure technology, specifically, it relates to a light steel keel decorative structure for residential interior decoration and its usage method. Background Technology

[0002] Light steel keel decorative structure is an interior decoration system formed by using light steel keel as the framework and matching it with various covering panels (such as gypsum board, calcium silicate board, etc.). Its core advantages are lightweight, high strength, fire resistance, moisture resistance, and convenient construction: the weight of light steel material is only one-third that of wood keel, but it has a higher resistance to deformation. The galvanizing process effectively resists rust in humid environments and extends service life. The modular design allows the keel and the panel to be quickly connected by clips or screws, which greatly shortens the construction period. This structure is widely used in ceilings, partitions, and background walls. It can achieve various shapes such as straight lines and curves through flexible combination, and can also integrate functions such as pipeline concealment, sound insulation, and heat insulation. It is the mainstream choice in modern interior decoration that combines efficiency and performance.

[0003] Among the common types of light steel keel, clip-on keel has become one of the most commonly used keel types for home decoration ceilings due to its advantages such as strong structural stability, high construction efficiency, good corrosion resistance, diverse functions, and economic and environmental protection. However, the installation position of the main beam requires high precision during the installation process. If the clip teeth of two main beams are misaligned, the secondary beam will be difficult to snap into place with the clip teeth, or the snap-in will be difficult, thus affecting the installation efficiency. Based on this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a light steel keel decorative structure for residential interior decoration that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a light steel keel decorative structure for residential interior decoration, including a main beam, and further including: a limiting slide rail assembly installed on the main beam, with a hanging member slidably connected to the limiting slide rail assembly; a snap-fit ​​member is hung on the hanging member, the snap-fit ​​member has a snap-fit ​​interface, and a secondary beam assembly is snap-fitted onto the snap-fit ​​member; side beams are installed at both ends of the secondary beam assembly, and the side beams are installed on the wall or plasterboard; the snap-fit ​​member and the hanging member are slidably connected, and when the snap-fit ​​interface on the snap-fit ​​member is misaligned with the adjacent one, the snap-fit ​​member can be slidably aligned; the snap-fit ​​member can be slid out and removed from the side, and when the secondary beam assembly is snapped onto the snap-fit ​​member, multiple sets of snap-fit ​​members are fixed as a whole.

[0006] Preferably, the hook-up component includes a first hook-up bend, a support rod, and a second hook-up bend. The support rod is fixedly connected to the first hook-up bend. The support rods on both sides of the hook-up component are designed in an alternating manner. The main beam is provided with a support bend plate. The first hook-up bend is hooked onto the support bend plate. A reinforcing support plate is connected between the support bend plate and the main beam.

[0007] Furthermore, the limiting slide rail assembly includes a limiting groove block, a compression spring, a limiting rod, and a pressing bolt. The limiting groove block is fixedly connected to the limiting rod, the limiting rod is slidably connected to the main beam, the pressing bolt is connected to the main beam via threads, and the pressing bolt is used to press and fix the limiting groove block. The compression spring is connected between the main beam and the limiting groove block.

[0008] Furthermore, the snap-fit ​​component includes a snap-fit ​​plate, a support plate, and a third hook-fit bend. The snap-fit ​​plate has an outward octagonal design and a snap-fit ​​interface. The support plate is located between the two third hook-fit bends and has reinforcing ribs.

[0009] Furthermore, a limiting block is provided on the first hook-up bend, the limiting block is slidably connected to the limiting groove block, and the extrusion bolt extrudes the limiting groove block to push the hook-up piece to fit and fix against the side wall of the support bend plate.

[0010] Furthermore, the second hook bend is provided with a limiting oblique block, and the third hook bend is provided with a limiting oblique opening. The snap-fit ​​component is engaged with the second hook bend through the third hook bend. When the hook components on both sides move towards the middle, the limiting oblique block engages with the limiting oblique opening, and the support rod abuts against the opposite hook component.

[0011] Preferably, the sub-beam assembly includes a sub-beam body, an adjusting bolt, and a pressing block. The adjusting bolt is rotatably connected to the pressing block, and the pressing block is slidably connected to the sub-beam body. The sub-beam body is provided with a snap-fit ​​connector, and the sub-beam body engages with the snap-fit ​​connector through the snap-fit ​​connector.

[0012] Furthermore, the sub-beam body is provided with a limiting pull plate, the limiting pull plate is provided with a guide inclined block, and the extrusion block is provided with an extrusion inclined block. When the extrusion block moves down, the extrusion limiting pull plate pulls the clamping joint to the center for engagement. The adjusting bolt is connected to an adjusting nut by a thread.

[0013] Preferably, the main beam has an installation hole, and a hanger rod is installed in the installation hole and installed in the top wall.

[0014] A method for installing a light steel keel decorative structure for residential interior decoration mainly includes the following steps:

[0015] S1. Fix the hanger and the side beam to the top of the wall and the side wall respectively, and install the main beam on the hanger;

[0016] S2. Attach the snap-fit ​​component to the hanger component and secure the snap-fit ​​component by rotating the compression bolt;

[0017] S3. Insert the sub-beam assembly into the card interface, and make the card connector and card interface tightly fastened by rotating the adjusting nut;

[0018] S4. Connect the main body of the sub-beam to the side beam, fix it with screws, and seal it with plasterboard.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. This invention features adjustable snap-fit ​​connectors on the main beam. This allows the snap-fit ​​connectors to be adjusted to ensure that each set of snap-fit ​​connectors is aligned with the others, even if the main beam is misaligned during installation. This makes it easier for users to snap the sub-beam components into the snap-fit ​​connectors, avoiding rework due to misalignment during installation or drilling, and greatly improving the error tolerance and installation efficiency.

[0021] 2. By setting the snap-fit ​​component as an independent unit and setting the hanger and limiting slide rail assembly in the main beam, the present invention facilitates the installation and disassembly of the snap-fit ​​component and avoids irreversible damage when dismantling or adjusting the installed keel structure.

[0022] 3. By setting up a sub-beam assembly, rotating the adjusting nut allows the adjusting bolt to drive the pressing block downwards, pulling the limiting plate closer to the center. This enables the limiting plate to pull the snap-fit ​​connector tightly into the snap-fit ​​interface, thereby improving the load-bearing capacity of the sub-beam assembly.

[0023] The parts not covered in this device are the same as or can be implemented using existing technology. This invention can adjust the position of the card interface by sliding the card connector so that each group of card interfaces is aligned with each other, avoiding the need for rework due to misalignment during installation or drilling, improving the fault tolerance and installation efficiency during installation, facilitating the installation and disassembly of the card connector, and improving the load-bearing capacity of the sub-beam assembly.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] Example 1: Refer to Figures 1-10 A light steel keel decorative structure for residential interior decoration includes a main beam 1, and further includes: a limiting slide rail assembly 3 installed on the main beam 1, with a hanging piece 2 slidably connected to the limiting slide rail assembly 3; a snap-fit ​​piece 4 is hung on the hanging piece 2, and a snap-fit ​​interface 411 is opened on the snap-fit ​​piece 4; a secondary beam assembly 5 is snap-fitted on the snap-fit ​​piece 4, and side beams 6 are installed at both ends of the secondary beam assembly 5, which are installed on the wall or plasterboard; the snap-fit ​​piece 4 is slidably connected to the hanging piece 2, and when the snap-fit ​​interface 411 on the snap-fit ​​piece 4 is misaligned with the adjacent one, the snap-fit ​​piece 4 can be slidably aligned; when the secondary beam assembly 5 is snap-fitted onto the snap-fit ​​piece 4, multiple sets of snap-fit ​​pieces 4 are fixed as a whole.

[0038] In this invention, since the main beam 1 is often fixed to the wall top with expansion bolts, if the installation position of each set of main beams 1 cannot be guaranteed to be the same during drilling or installation, it will lead to difficulties or failure to connect the subsequent snap-fit ​​sub-beam assembly 5 to the snap-fit ​​interface 411. The difference between this invention and existing devices is that by setting a sliding adjustable snap-fit ​​part 4 on the main beam 1, even if the main beam 1 is offset during installation, the position of the snap-fit ​​interface 411 can be adjusted by sliding the snap-fit ​​part 4, so that each set of snap-fit ​​interfaces 411 are aligned with each other, making it convenient for the user to snap-fit ​​the sub-beam assembly 5 into the snap-fit ​​interface 411. This avoids the need for rework due to misalignment during installation or drilling, greatly increasing the error tolerance during installation. At the same time, since the snap-fit ​​part 4 can slide when the sub-beam assembly 5 is snapped into the snap-fit ​​interface 411, the snap-fit ​​part 4 can automatically slide to the most convenient snap-fit ​​position during the snap-fit ​​process, thus greatly saving the force used during snap-fit ​​and facilitating the installation of construction personnel.

[0039] To ensure the load-bearing capacity of the keel structure, the connection between the sub-beam and the main beam 1 is usually quite tight, making disassembly difficult. In this invention, the snap-fit ​​part 4 is an independent unit, which can freely install and disassemble the snap-fit ​​part 4 and the main beam 1. This allows the snap-fit ​​part 4 and the sub-beam assembly 5 to be directly removed together when the installed keel structure needs to be disassembled or adjusted, thus avoiding the situation where the sub-beam assembly 5 is difficult to disassemble due to the tight connection between the sub-beam assembly 5 and the snap-fit ​​interface 411.

[0040] Once the sub-beam assembly 5 and the snap-fit ​​connector 4 are engaged, the sub-beam assembly 5 and the snap-fit ​​connector 4 are fixed as a whole. This eliminates the need for horizontal fixing with the snap-fit ​​connector 4. The installation can be completed simply by fixing the sub-beam assembly 5 according to the normal procedure at the end, thus avoiding unnecessary installation operations caused by adding a structure.

[0041] Example 2: Refer to Figure 1 - Figure 10 A light steel keel decorative structure for residential interior decoration is basically the same as that in Embodiment 1, but with a further improvement: the hanging member 2 includes a first hanging bend 21, a support rod 22, and a second hanging bend 23. The support rod 22 is fixedly connected to the first hanging bend 21. The support rods 22 on both sides of the hanging member 2 are designed in an interlaced manner. A support bend plate 13 is provided on the main beam 1. The first hanging bend 21 is hung on the support bend plate 13. A reinforcing support plate 12 is connected between the support bend plate 13 and the main beam 1. The limiting slide rail assembly 3 includes a limiting groove block 31, a compression spring 32, a limiting rod 33, and a pressing bolt 34. The limiting groove block 31 is fixedly connected to the limiting rod 33. The limiting rod 33 is slidably connected to the main beam 1. The pressing bolt 34 is connected to the main beam 1 through threads. The pressing bolt 34 is used to press and fix the limiting groove block 31. The compression spring 32 is connected between the main beam 1 and the limiting groove. Between blocks 31, the snap-fit ​​component 4 includes a snap-fit ​​plate 41, a support plate 42, and a third hook-fit bend 43. The snap-fit ​​plate 41 has an outward octagonal design and a snap-fit ​​interface 411. The support plate 42 is located between the two third hook-fit bends 43 and has reinforcing ribs 421. The first hook-fit bend 21 has a limiting block 211, which is slidably connected to the limiting groove block 31. The pressing bolt 34 presses against the surface. The limiting groove block 31 pushes the hook 2 to fit and fix against the side wall of the support bend plate 13. The second hook bend 23 is provided with a limiting inclined block 231, and the third hook bend 43 is provided with a limiting inclined opening 431. The snap-fit ​​4 is engaged with the second hook bend 23 through the third hook bend 43. When the hook 2 on both sides moves towards the middle, the limiting inclined block 231 engages with the limiting inclined opening 431, and the support rod 22 abuts against the opposite hook 2.

[0042] In this invention, such as Figure 4 and Figure 6As shown, the hanger 2 is composed of a first hanger bend 21, a support rod 22 and a second hanger bend 23. The first hanger bend 21 is hung on the support bend plate 13. A reinforcing support plate 12 is connected between the support bend plate 13 and the main beam 1 to increase the support force of the support bend plate 13. A limiting block 211 is fixedly connected to the first hanger bend 21. The limiting block 211 and the limiting groove block 31 are interlocked and form a sliding connection, so that the limiting groove block 31 can drive the hanger 2 as a whole to move horizontally in the direction of the force applied by the compression spring 32. The second hanger bend 23 is used to hang the snap fastener 4. The snap fastener 4 is hung on the second hanger bend 23 through the third hanger bend 43, thereby realizing the installation connection between the snap fastener 4 and the main beam 1.

[0043] The limiting slide rail assembly 3 consists of a limiting groove block 31, a compression spring 32, a limiting rod 33, and a clamping bolt 34. The compression spring 32 mainly provides a continuous elastic thrust for the hook-up piece 2, thereby ensuring that the snap-fit ​​piece 4 can automatically hook onto the second hook-up bend 23 by pushing upwards during installation. The clamping bolt 34 is threadedly connected to the main beam 1. By rotating the clamping bolt 34, the limiting groove block 31 can be pushed forward to make the first hook-up bend 21 fit against the support bend plate 13 to form a clamping fixation. A support rod 22 is fixedly connected to the first hook-up bend 21. The support rods 22 on the two sides of the hanger 2 are arranged in an alternating manner. When the hanger 2 on both sides is pushed and clamped by the compression bolts 34, the support rods 22 abut against the hanger 2 in opposite directions, thereby further improving the stability of the hanger 2. The limiting rod 33 is fixedly connected to the limiting groove block 31, and the limiting rod 33 is slidably connected to the main beam 1, thereby supporting and limiting the limiting groove block 31. At the same time, the construction personnel can also pull the limiting rod 33 from the outside to move the hanger 2 to release the clamping restriction on the snap-fit ​​4, thereby completing the removal operation of the snap-fit ​​4.

[0044] The third hook-up bend 43 has a limiting angled opening 431, and the second hook-up bend 23 has a limiting angled block 231. When the hook-up pieces 2 are close to each other, the limiting angled block 231 will be inserted into the limiting angled opening 431, thereby clamping and fixing the hook-up piece 4 and preventing the hook-up piece 4 from moving in the vertical direction. The third hook-up bends 43 on both sides are connected by a support plate 42, and the support plates 42 are connected by a reinforcing rib 421, which can improve the deformation resistance of the hook-up piece 4 and ensure that no deformation or damage will occur during the docking process of the limiting angled block 231 and the limiting angled opening 431.

[0045] Example 3: Reference Figure 1 - Figure 10A light steel keel decorative structure for residential interior decoration is basically the same as that in Embodiment 2, but with a further improvement: the sub-beam assembly 5 includes a sub-beam body 51, an adjusting bolt 52, and a pressing block 53. The adjusting bolt 52 is rotatably connected to the pressing block 53, and the pressing block 53 is slidably connected to the sub-beam body 51. The sub-beam body 51 is provided with a snap-fit ​​connector 512, which engages with the snap-fit ​​interface 411 through the snap-fit ​​connector 512. The sub-beam body 51 is provided with a limiting pull plate 511, which is provided with a guide inclined block 5111. The pressing block 53 is provided with a pressing inclined block 531. When the pressing block 53 moves down, the pressing limiting pull plate 511 pulls the snap-fit ​​connector 512 to engage with the center. The adjusting bolt 52 is connected to an adjusting nut 521 by a thread. The main beam 1 is provided with an installation hole 11, and a hanger 7 is provided in the installation hole 11. The hanger 7 is installed in the top wall.

[0046] In this invention, the snap-fit ​​plate 41 has a snap-fit ​​interface 411. The snap-fit ​​plate 41 is designed with an outward V-shape, which increases the width of the bottom of the snap-fit ​​plate 41 and improves the stability of the sub-beam assembly 5 after it is snapped with the snap-fit ​​plate 41. The sub-beam assembly 5 is different from the common sub-beam in that it has a limiting pull plate 511 and a pressing block 53 inside. When the pressing block 53 moves down, it can pull the limiting pull plate 511 closer to the center through the pressing inclined block 531, so that the limiting pull plate 511 can pull the snap-fit ​​connector 512 to be tightly fastened with the snap-fit ​​interface 411, thereby improving the load-bearing capacity of the sub-beam assembly 5. The adjusting bolt 52 is rotatably connected to the pressing block 53. By rotating the adjusting nut 521, the adjusting bolt 52 can drive the pressing block 53 to move downward. The bottom of the sub-beam body 51 is connected to the side beam 6, and the fixation between the sub-beam body 51 and the side beam 6 is completed by driving screws from the bottom.

[0047] The mounting hole 11 is positioned opposite to the support rod 22 to prevent the support rod 22 from interfering with the installation of the hanger 7 and the main beam 1.

[0048] Example 4: Reference Figure 1 - Figure 10 A method for using a light steel keel decorative structure in residential interior decoration mainly includes the following steps:

[0049] S1. Determine the installation positions of the hanger 7 and the side beam 6, drill holes in the wall, fix the hanger 7 and the side beam 6 to the wall, insert the hanger 7 into the installation hole 11 and install and fix the main beam 1.

[0050] S2. Push the snap-fit ​​part 4 into the interior of the main beam 1 from below. Under the guidance of the limiting inclined block 231 and the compression spring 32, the snap-fit ​​part 4 automatically hooks onto the second hook-fit bend 23. Then rotate the pressing bolt 34 to push the limiting groove block 31 and the hook-fit part 2 toward the center to initially limit the snap-fit ​​part 4 and ensure that the snap-fit ​​part 4 can slide and adjust.

[0051] S3. Attach the sub-beam assembly 5 to the card interface 411, and align the sub-beam assembly 5 with the card connector 4 by sliding the sub-beam assembly 5, and rotate the adjusting nut 521 to make the card connector 512 move closer to the center and clamp it, and rotate the clamping bolt 34 again to clamp and limit the card connector 4.

[0052] S4. Place the main body of the secondary beam 51 on the side beam 6, and drive in screws to fix the main body of the secondary beam 51 to the side beam 6. Finally, seal the ceiling with plasterboard to complete all the work of the suspended ceiling.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
