Description

Technical Field

[0001] This utility model relates to the field of building decoration engineering technology, and in particular to a close splicing device for aluminum ceiling panels. Background Technology

[0002] Currently, aluminum ceiling panels with steep slopes are widely used in large public buildings such as airports with long spans. The traditional installation method uses a keel hanger system, which has the following technical defects: misalignment is prone to occur at the joints of adjacent ceiling panels, affecting the overall aesthetics; the flatness of the ceiling panels is difficult to control under steep slope conditions, and wavy deformation is easy to occur; repeated adjustments to misalignment and flatness are required during installation, resulting in low construction efficiency; existing leveling devices cannot adapt to steep slope conditions and have insufficient stability.

[0003] The conventional solutions to the aforementioned technical defects are to add suspension points or level the panels on-site using shims. However, this leads to longer construction periods, increased costs, and fails to fundamentally solve the problem of misalignment at the joints. Therefore, there is a need for a close-fitting device for aluminum ceiling panels that can solve the problems of misalignment at the joints of adjacent aluminum ceiling panels and difficulty in controlling the flatness of the ceiling panels in existing technologies. Summary of the Invention

[0004] The purpose of this utility model is to provide a tight splicing device for aluminum ceiling panels, which can solve the problems of misalignment at the joints of adjacent aluminum ceiling panels and difficulty in controlling the flatness of the ceiling panels in the prior art.

[0005] This utility model is implemented as follows:

[0006] A ceiling aluminum panel splicing device includes a ceiling aluminum panel, a limiting washer, and a bolt and nut assembly. Sliding grooves are formed on both sides of the ceiling aluminum panel. One end of the bolt and nut assembly is slidably embedded in the sliding groove of the ceiling aluminum panel, and the other end of the bolt and nut assembly extends upward through the sliding groove. The limiting washer has several connecting holes spaced apart. The other end of the bolt and nut assembly passes through the connecting holes and is adjustablely connected to the limiting washer. The limiting washer is positioned at a fixed suspension point of the ceiling system and at the splicing point of several adjacent ceiling aluminum panels, allowing the adjacent ceiling aluminum panels to be adjusted and spliced ​​tightly below the limiting washer via the bolt and nut assembly.

[0007] The sliding groove has an inverted T-shaped structure. The upper end of the sliding groove extends upward through the top surface of the ceiling aluminum panel. The bolt head of the bolt and nut assembly is slidably set in the horizontal section of the sliding groove. The bolt section of the bolt and nut assembly extends upward through the vertical section of the sliding groove through the ceiling aluminum panel and the limiting washer.

[0008] A reserved hole is formed on the vertical section of the sliding groove. The reserved hole communicates downward with the horizontal section of the sliding groove, and the diameter of the reserved hole is larger than the diameter of the bolt head of the bolt and nut assembly, so that the bolt head of the bolt and nut assembly is fitted into the horizontal section of the sliding groove through the reserved hole.

[0009] The sliding groove is set along the short side of the ceiling aluminum panel, and the length of the sliding groove is the same as the width of the ceiling aluminum panel.

[0010] The bolt section of the bolt and nut assembly is provided with scale lines.

[0011] The limiting gasket has a square planar plate structure. Four connecting holes are symmetrically arranged at the four corners of the limiting gasket, so that when four adjacent ceiling aluminum panels or two adjacent ceiling aluminum panels are spliced ​​together, the limiting gasket is connected to the four adjacent ceiling aluminum panels or two adjacent ceiling aluminum panels through the four connecting holes and four sets of bolt and nut groups respectively.

[0012] The bolt segment length of the bolt and nut assembly is greater than the sum of the depth of the sliding groove and the thickness of the ceiling aluminum plate.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. This utility model, by incorporating a limiting washer and a bolt-nut assembly, allows the ceiling aluminum panel to be connected to the bottom of the limiting washer via vertically arranged bolts. The limiting washer is installed at a fixed suspension point, thereby suspending the ceiling aluminum panel below the fixed suspension point. The installation height of the ceiling aluminum panel is adjusted by rotating the threads between the bolt and nut, avoiding height differences between adjacent ceiling aluminum panels, ensuring the flatness of the ceiling panel after splicing, and improving the aesthetics of the ceiling panel. This solves the problem of difficulty in controlling the flatness of ceiling panels in the prior art. At the same time, the thread engagement between the bolt and nut ensures reliable installation of the ceiling aluminum panel at the fixed suspension point and reliable tight splicing between adjacent ceiling aluminum panels.

[0015] 2. Because this utility model has a sliding groove, the bolt head of the bolt and nut assembly can slide freely along the sliding groove, thereby adjusting the horizontal position of the ceiling aluminum panel installation. This ensures that the joints of each ceiling aluminum panel can be aligned, avoiding construction defects such as misalignment of the joints. In addition, the joints between adjacent ceiling aluminum panels are tight, ensuring the tight splicing and aesthetics of the ceiling panels.

[0016] 3. This utility model has the advantages of convenient installation, easy leveling, high precision, and strong adaptability. It can be applied to the ceiling construction of large-span and steep-slope public buildings such as airports, high-speed rail stations, and convention centers. Through modular construction, it can significantly improve the installation accuracy and construction efficiency of ceiling panels, reduce material waste by more than 30%, and shorten the construction period by 40%, which has significant economic benefits and engineering application value.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Please see the appendix Figure 1 To be continued Figure 7 A ceiling aluminum panel splicing device includes a ceiling aluminum panel 1, a limiting washer 2, and a bolt and nut assembly 3. Sliding grooves 11 are formed on both sides of the ceiling aluminum panel 1. One end of the bolt and nut assembly 3 is slidably embedded in the sliding groove 11 of the ceiling aluminum panel 1, and the other end of the bolt and nut assembly 3 extends upward through the sliding groove 11. A plurality of connecting holes 21 are formed at intervals on the limiting washer 2. The other end of the bolt and nut assembly 3 passes through the connecting holes 21 through the limiting washer 2 and is adjustablely connected to the limiting washer 2. The limiting washer 2 is located at the fixed suspension point of the ceiling system and at the splicing point of several adjacent ceiling aluminum panels 1, so that several adjacent ceiling aluminum panels 1 are adjustablely spliced ​​under the limiting washer 2 by the bolt and nut assembly 3.

[0027] The limiting gasket 2 can be fixedly installed at the fixed suspension point of the ceiling system, such as the bottom of the fixed suspension rod, and can be installed adaptably according to the actual working conditions. Preferably, the limiting gasket 2 can be made of aluminum alloy plate. The ceiling aluminum plate 1 is used to suspend the ceiling aluminum plate 2 at the bottom by bolt and nut assembly 3, thereby installing the ceiling aluminum plate 1 below the fixed suspension point. Several ceiling aluminum plates 1 are installed in sequence to form a ceiling panel. Every two adjacent ceiling aluminum plates 1 or every four adjacent ceiling aluminum plates 1 are adjusted and tightly spliced ​​by the limiting gasket 2 and bolt and nut assembly 3.

[0028] Preferably, the bolt and nut assembly 3 may include bolts, nuts, and washers from the prior art. One end of the bolt is slidably disposed within the sliding groove 11 for connection with the ceiling aluminum panel 1 and its position can be slidably adjusted, thereby allowing the joints of adjacent ceiling aluminum panels 1 to be aligned through relative sliding, improving the aesthetics of the ceiling panels. The other end of the bolt vertically passes through the connecting hole 21 of the limiting washer 2. The nut is screwed onto the bolt and locked onto the limiting washer 2 by the washer. The installation height of the ceiling aluminum panel 1 at the bottom of the limiting washer 2 can be adjusted by rotating the threads between the bolt and the nut, thereby achieving height adjustment and ensuring the flatness of the ceiling panel. At the same time, the thread engagement between the bolt and the nut ensures the reliability of the installation and splicing of the ceiling aluminum panel 1.

[0029] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 7 The sliding groove 11 has an inverted T-shaped structure. The upper end of the sliding groove 11 extends upward through the top surface of the ceiling aluminum plate 1. The bolt head of the bolt and nut assembly 3 is slidably set in the horizontal section of the sliding groove 11. The bolt section of the bolt and nut assembly 3 extends upward through the vertical section of the sliding groove 11 through the ceiling aluminum plate 1 and the limiting washer 2.

[0030] The sliding groove 11 is designed as an inverted T-shaped structure, which allows the bolt head of the bolt and nut assembly 3 to slide freely in the horizontal section of the sliding groove 11 without coming off vertically. This ensures the horizontal adjustment of the ceiling aluminum panel 1, so as to achieve sliding adjustment and alignment of the joint position.

[0031] The shape of the sliding groove 11 can also be adapted to the actual use requirements. The size of the sliding groove 11 can be adapted to the bolt specifications of the bolt and nut group 3, so as to ensure that the bolt head can slide freely in the sliding groove 11 without being too loose.

[0032] Please see the appendix Figure 7A reserved hole 12 is formed on the vertical section of the sliding groove 11. The reserved hole 12 is connected downward to the horizontal section of the sliding groove 11, and the diameter of the reserved hole 12 is slightly larger than the diameter of the bolt head of the bolt nut assembly 3, so that the bolt head of the bolt nut assembly 3 is fitted into the horizontal section of the sliding groove 11 through the reserved hole 12.

[0033] Since the bolt head is larger than the vertical section of the sliding groove 11, the pre-drilled hole 12 facilitates the insertion of the bolt head into the horizontal section of the sliding groove 11. When adjusting the ceiling aluminum panel 1, it is only necessary to offset the final fixing position of the bolt and nut assembly 3 from the pre-drilled hole 12 to prevent the ceiling aluminum panel 1 from falling off the limiting washer 2.

[0034] Preferably, reserved holes 12 can be provided at both ends of the sliding groove 11.

[0035] Please see the appendix Figure 7 The sliding groove 11 is provided along the short side of the ceiling aluminum plate 1, and the length of the sliding groove 11 is the same as the width of the ceiling aluminum plate 1.

[0036] Typically, the ceiling aluminum panel 1 is a rectangular panel. Preferably, the sliding groove 11 can also be set along the long side of the ceiling aluminum panel 1 or along the four sides of the ceiling aluminum panel 1 to meet the horizontal adjustment in different directions and ensure the aesthetic appearance of the overall ceiling panel joints.

[0037] By extending the sliding groove 11 along the entire length of the ceiling aluminum plate 1, the bolts of the bolt and nut assembly 3 can be inserted into the sliding groove 11 from the end of the sliding groove 11, making disassembly and assembly convenient.

[0038] Please see the appendix Figure 6 The bolt section of the bolt and nut assembly 3 is provided with scale lines 31.

[0039] By setting the scale line 31, the rotation adjustment between the nut and bolt of the bolt and nut group 3 can be more precise, so as to ensure the accurate installation height of the ceiling aluminum panel 1.

[0040] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The limiting gasket 2 has a square planar plate structure. Four connecting holes 21 are symmetrically arranged at the four corners of the limiting gasket 2, so that when four adjacent ceiling aluminum panels 1 or two adjacent ceiling aluminum panels 1 are spliced ​​together, the limiting gasket 2 is connected to the four adjacent ceiling aluminum panels 1 or two adjacent ceiling aluminum panels 1 through the four connecting holes 21 and four sets of bolt and nut groups 3 respectively.

[0041] When setting the reserved hole 12, the position of the reserved hole 12 should be offset from the position of the connecting hole 21 on the limiting pad 2, so as to ensure that when the ceiling aluminum plate 1 is installed to the bottom of the limiting pad 2 by the bolt and nut assembly 3, the bolt and nut assembly 3 is offset from the reserved hole 12, thereby ensuring that the bolt and nut assembly 3 is reliably connected to the ceiling aluminum plate 1 through the sliding groove 11, and ensuring that the ceiling aluminum plate 1 will not fall.

[0042] The four pre-drilled holes 12 are symmetrically arranged on the square limiting pad 2. The center of the limiting pad 2 can be firmly connected to the fixed suspension point, ensuring that when two or four adjacent ceiling aluminum panels 1 are spliced ​​under the limiting pad 2, the limiting pad 2 is subjected to uniform force and the installation is reliable.

[0043] Please see the appendix Figure 3 The bolt segment length of the bolt and nut assembly 3 is greater than the sum of the depth of the sliding groove 11 and the thickness of the ceiling aluminum plate 1, so as to ensure that the installation height of the ceiling aluminum plate 1 has a certain adjustment space, thereby meeting the flatness adjustment requirements of the ceiling plate.

[0044] The bolt segment length of the bolt and nut assembly 3 can be adaptively adjusted according to the actual height adjustment requirements. Preferably, the installation height range of the ceiling aluminum panel 1 can be 0-5mm.

[0045] Please see the appendix Figure 1 To be continued Figure 7 The installation method and adjustment method of this utility model are as follows:

[0046] The center of the limiting washer 2 is fixedly installed at the bottom of the fixed hanger of the ceiling system. When installing the ceiling aluminum panel 1, the bolt head of the bolt nut group 3 is embedded into the horizontal section of the sliding groove 11 through the reserved hole 12. A set of bolt nut group 3 is set at each of the four corners of each ceiling aluminum panel 1. The ceiling aluminum panel 1 with bolts is hoisted to the limit washer 2 below the installation position.

[0047] The bolt segment is inserted vertically upwards through the connecting hole 21 on the limiting washer 2, and then connected and fixed to the limiting washer 2 by the washer and nut, thus installing the ceiling aluminum panel 1 at the bottom of the fixed hanger. According to the design elevation of the ceiling aluminum panel 1, the installation height of the ceiling aluminum panel 1 can be adjusted by rotating the thread between the nut and the bolt in the bolt and nut assembly 3.

[0048] When splicing two adjacent ceiling aluminum panels 1, the limiting washer 2 is connected to each ceiling aluminum panel 1 through two connecting holes 21 and two sets of bolt and nut groups 3. When splicing two adjacent ceiling aluminum panels 1, the limiting washer 2 is connected to each ceiling aluminum panel 1 through one connecting hole 21 and one set of bolt and nut groups 3. Multiple ceiling aluminum panels 1 are sequentially hoisted and spliced ​​to form a ceiling panel.

[0049] If there are misalignments between the ceiling aluminum panels 1, the panels 1 can be slid along the sliding groove 11 to align their seams. If there are height differences between the ceiling aluminum panels 1, the height can be adjusted by rotating the threads of the bolts and nuts. Each of the four corners of each panel 1 can be adjusted individually using the bolt and nut assembly 3, ensuring the flatness of the assembled ceiling and guaranteeing precise positioning and tight splicing of the ceiling aluminum panels 1.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
