Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a stably installed suspended ceiling structure. Background Art

[0002] The common existing ceiling structure mainly hides pipelines, wires and other facilities, makes the room more tidy and beautiful, and increases the sense of hierarchy and design of the space. Correspondingly, the structure of the ceiling mainly includes mounting parts and ceiling panels. Among them, the mounting parts are generally fixed on the ceiling, while the ceiling panels are perpendicular to the wall and lower than the ceiling.

[0003] Therefore, the necessary conditions for the stability of the suspended ceiling structure at least include: the mounting parts are stable on the ceiling and the mounting parts are firmly connected to the plate body.

[0004] For example, the Chinese utility model patent with authorization announcement number CN220978540U and authorization announcement date 2024.05.17 discloses a device for connecting and fixing a suspended ceiling, whose structure includes: a mounting plate, expansion screws, through holes, angle steel, bolt one, vertical beam, bolt two, nuts, mounting blocks, hanging frames, tenons, extension plates, tenons, guide grooves, locking rods, pull plates, springs, bevel grooves, lock grooves, and locking components.

[0005] The main advantages of the ceiling device in this utility model patent are: through the coordinated use of the mortise and tenon, the hanging frame can be easily replaced to avoid damage to the hanging frame, and the overall components can be replaced, which reduces the cost of use, and the replacement is convenient and quick, providing convenience of use.

[0006] However, the ceiling device still has at least the following shortcomings during actual use, namely:

[0007] The overall stability of the device is relatively low. Specifically, it is difficult to find the expansion screw structure in time after it falls, and the hanging frame and the ceiling panel only have a plug-in relationship, so the latter is relatively easy to slide laterally on the former and then fall. Summary of the invention

[0008] The present invention provides a stably installed suspended ceiling structure, and the technical problem to be solved is how to ensure sufficient installation stability between the suspended ceiling plate and the installation piece, and between the installation piece and the ceiling.

[0009] The technical solution adopted by the present invention to solve the above-mentioned problem is: a stably installed ceiling structure, including a ceiling panel, a mounting plate, fastening bolts, a connecting column, and a plug-in frame, and also including a perforated hanging plate unit arranged on the upper surface of the ceiling panel and used to insert the plug-in frame, a plug-in rod unit arranged on the connecting column and used to plug the perforated hanging plate unit, a perforated inclined plate unit sleeved on the connecting column, and an elastic lifting baffle unit arranged on the connecting column and supporting the perforated inclined plate unit, and changing the shading amplitude of the light strip by pressing down the perforated inclined plate unit after the fastening bolt falls, so as to display that the fastening bolt has fallen.

[0010] A further preferred technical solution is that the perforated suspension plate unit includes a vertical plate arranged on the upper surface of the ceiling plate, a transverse plate arranged on the vertical plate, and a limiting hole arranged on the transverse plate and used for plugging the plug-in rod unit.

[0011] A further preferred technical solution is that the plug-in rod unit includes a wall side perforated plate arranged on the connecting column, and a limiting rod plugged into the wall side perforated plate and inserted into the limiting hole to laterally fix the ceiling panel.

[0012] A further preferred technical solution is that the perforated inclined plate unit includes an inclined plate whose lower surface is arranged on the elastic lifting baffle unit and is used to receive the fastening bolts that have fallen, and a transverse limiting hole arranged on the inclined plate and is used to insert the connecting column.

[0013] A further preferred technical solution is that the elastic lifting baffle unit includes a side perforated plate of the light strip arranged on the connecting column, a lifting vertical plate which is plugged into the side perforated plate of the light strip, supports the inclined plate, and is used to perform shading operations on the light strip, a limit block which is arranged on the lifting vertical plate and is located above the side perforated plate of the light strip, and a lifting spring which is arranged on the side perforated plate of the light strip and is used to support the limit block.

[0014] A further preferred technical solution is that: the upper surface of the ceiling plate is also provided with a bolt blocking strip for changing the luminous amplitude of the light strip by blocking the fastening bolts that slide off the elastic lifting baffle unit.

[0015] A further preferred technical solution is that: an anti-loss baffle for preventing the fastening bolts from sliding off the elastic lifting baffle unit is provided on one side of the mounting plate close to the light strip.

[0016] A further preferred technical solution is that the plug-in rod unit also includes a movable ring sleeved on the limit rod and located above the wall side perforated plate, and a support spring arranged on the wall side perforated plate and used to support the movable ring.

[0017] A further preferred technical solution is that the perforated inclined plate unit also includes a blocking and silencing dual-purpose strip arranged on the inclined plate and used to block the fastening bolts that have fallen or pressed on the elastic lifting baffle unit.

[0018] A further preferred technical solution is that: the upper surface of the ceiling plate is further provided with positioning grooves which are located at both sides of the connecting column and the plug-in rod unit and are used to install the light strip.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] First, the mounting piece of the ceiling structure includes a mounting plate, a connecting column and a plug-in frame, and the ceiling plate is plugged in with the mounting piece through a hanging plate unit with holes and limited by a plug-in rod unit, thereby ensuring that the ceiling plate and the mounting piece are stably mounted.

[0021] Second, after the fastening bolt falls, it may fall on the perforated inclined plate unit or the ceiling plate. The above two results can change the luminous amplitude of the light strip, thereby indicating that a fastening bolt has fallen. The user can install it back and tighten it in time, which indirectly makes the installation between the mounting piece and the ceiling stable.

[0022] Third, the above-mentioned ceiling plate anti-falling function and the function of timely detection after the fastening bolt falls do not affect each other, and it does not matter whether the plug-in rod unit supports the perforated inclined plate unit;

[0023] Fourthly, the fastening bolts are not easily lost after falling, that is, they are always located on the ceiling structure and are not easily dropped on the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0043] like Figure 1-Figure 10As shown, a stably installed ceiling structure includes a ceiling panel 11, a mounting plate 12, a fastening bolt 13, a connecting column 14, and a plug-in frame 15, and also includes a perforated suspension plate unit 1 arranged on the upper surface of the ceiling panel 11 and used to insert the plug-in frame 15, a plug-in rod unit 2 arranged on the connecting column 14 and used to plug the perforated suspension plate unit 1, a perforated inclined plate unit 3 sleeved on the connecting column 14, and an elastic lifting baffle unit 4 arranged on the connecting column 14, supporting the perforated inclined plate unit 3, and changing the shading amplitude of the light strip a by pressing down the perforated inclined plate unit 3 after the fastening bolt 13 falls, so as to display that the fastening bolt 13 has fallen.

[0044] In this embodiment, the mounting member of the ceiling structure includes a mounting plate 12, a connecting column 14 and a plug-in frame 15. The mounting member has the advantage of indirect and stable mounting between the mounting member and the ceiling. One implementation method can refer to the attached Figure 3 , as follows:

[0045] After the fastening bolt 13 loosens and falls, it falls on the perforated inclined plate unit 3, and the elastic force and the self weight of the elastic lifting baffle unit 4 are relatively small. Even the weight of one fastening bolt 13 is enough to make the elastic lifting baffle unit 4 drop significantly. At this time, the light strip a, which originally had a uniform luminous brightness everywhere, becomes significantly dimmer at this place, and then it can be displayed and indicated that the corresponding fastening bolt 13 at this place has fallen. The user who has already understood the use of the ceiling structure in advance can promptly reinstall the fallen bolt and tighten it, thereby finally achieving the effect of stable installation of the mounting parts.

[0046] The second implementation method can refer to the attached Figure 4 , as follows:

[0047] Similarly, the fastening bolt 13 loosens and falls, but it only rolls on the perforated inclined plate unit 3 and finally falls on the upper surface of the ceiling plate 11. At this time, it is not the elastic lifting baffle unit 4 that blocks the light strip a, but the fastening bolt 13 itself. The subsequent principle and response method are the same as one of the above methods, which also makes the installation part indirectly stable for a long time.

[0048] On the other hand, the guarantees for the ceiling panel 11 to be stably installed on the mounting member are: first, the perforated suspension panel unit 1 is horizontally inserted into the plug-in frame 15, so that the ceiling panel 11 is vertically stable and will not fall downward; second, the plug-in rod unit 2 is vertically inserted into the perforated suspension panel unit 1, so that the ceiling panel 11 is horizontally stable and will not easily slide outward.

[0049] The ceiling board 11 is a gypsum board or a wooden board, and the main materials of the mounting plate 12, the connecting column 14, the plug-in frame 15, the perforated suspension board unit 1, the plug-in rod unit 2, the perforated inclined board unit 3 and the elastic lifting baffle unit 4 are light steel or aluminum alloy. The correct installation method of the ceiling board 11 is to be horizontal and one side is against the wall b, which is the inner side of the ceiling structure, and the light strip a is on the relatively outer side of the ceiling structure.

[0050] In addition, the length of the ceiling plate 11 is 1-3m, and the mounting plate 12, the connecting column 14, the plug-in frame 15 and the perforated suspension plate unit 1 together constitute the mounting and connecting structure of the ceiling plate 11, and 3-5 of the structures are evenly arranged on a single ceiling plate 11. For details, please refer to the attached Figure 7 .

[0051] The perforated suspension plate unit 1 includes a vertical plate 101 arranged on the upper surface of the ceiling plate 11 , a horizontal plate 102 arranged on the vertical plate 101 , and a limiting hole 103 arranged on the horizontal plate 102 and used for plugging the plug-in rod unit 2 .

[0052] In this embodiment, the vertical plate 101 and the ceiling plate 11 are screwed together, the transverse plate 102 and the plug-in frame 15 are appropriately interference fit, and the insertion end point of the transverse plate 102 on the plug-in frame 15, that is, the plug-in frame 15 abuts against the vertical plate 101.

[0053] At this time, the limiting hole 103 is located directly below the plug-in rod unit 2. Before the ceiling panel 11 is installed or removed together with the perforated suspension panel unit 1, the plug-in rod unit 2 needs to be pulled upward in advance to release the lateral limiting effect on the perforated suspension panel unit 1.

[0054] The plug-in rod unit 2 includes a wall-side perforated plate 201 arranged on the connecting column 14 , and a limiting rod 202 inserted into the wall-side perforated plate 201 and inserted into the limiting hole 103 for transversely fixing the ceiling panel 11 .

[0055] In this embodiment, in order to stably install the ceiling panel 11, it is necessary to ensure that the limit rod 202 will not spontaneously separate from the limit hole 103. One way to achieve this effect is to appropriately interfere with the limit rod 202 and the opening structure on the wall side opening plate 201 to prevent the limit rod 202 from falling downward.

[0056] Of course, the structural rigidity of the plug-in rod unit 2 and the perforated suspension plate unit 1 is equally important, so the entire installation and connection structure is made of lightweight steel or aluminum alloy with relatively high rigidity.

[0057] At this point, the position of the ceiling panel 11 has been completely fixed. Unless the entire installation and connection structure itself is broken or disintegrated, the ceiling panel 11 is always in a stable installation state.

[0058] The perforated inclined plate unit 3 includes an inclined plate 301 whose lower surface is arranged on the elastic lifting baffle unit 4 and is used to receive the fastening bolts 13 that have fallen, and a transverse limiting hole 302 arranged on the inclined plate 301 and is used to insert the connecting column 14.

[0059] In this embodiment, the main function of the perforated inclined plate unit 3 is to trigger and maintain the relatively downward state of the elastic lifting baffle unit 4 by the weight of the fallen fastening bolt 13. At this time, the corresponding elastic lifting baffle unit 4 significantly increases the shading range of the light strip a, and a darker area will appear on the light strip a, and the fallen fastening bolt 13 can be discovered in time, thereby indirectly making the above-mentioned mounting part have the advantage of continuous stability.

[0060] Among them, the cross-sectional shape of the connecting column 14 is a rectangle, and the vertical projection shape of the horizontal limiting hole 302 is also a rectangle, and has the same size as the former, thereby ensuring that the inclined plate 301 cannot rotate vertically, cannot move and rotate horizontally, and can only be lifted vertically, that is, pressing down triggers the shading amplitude changing function of the elastic lifting baffle unit 4.

[0061] Correspondingly, the weight of the inclined plate 301 is relatively small, and lubricating oil or balls can be provided at the transverse limiting holes 302 as needed.

[0062] The elastic lifting baffle unit 4 includes a light strip side perforated plate 401 arranged on the connecting column 14, a lifting vertical plate 402 which is plugged into the light strip side perforated plate 401, supports the inclined plate 301, and is used to perform shading operation on the light strip a, a limit block 403 which is arranged on the lifting vertical plate 402 and is located above the light strip side perforated plate 401, and a lifting spring 404 which is arranged on the light strip side perforated plate 401 and is used to support the limit block 403.

[0063] In this embodiment, the weight of the elastic lifting baffle unit 4 and the elastic coefficient of the lifting spring 404 are relatively small, the lifting vertical plate 402 is rectangular in shape, and the light strip side perforated plate 401 is provided with a rectangular hole matching the lifting vertical plate 402, so that the lifting vertical plate 402 is not easy to tilt. Similarly, the opening on the light strip side perforated plate 401 can also be provided with lubricating oil or balls as needed.

[0064] In addition, the lifting plate 402 and the limit block 403 are integrally formed, and the width of the lifting plate 402 is relatively small, that is, the entire lifting plate 402 passes through the lifting spring 404. So far, as long as the fastening bolt 13 falls on the inclined plate 301, the lifting plate 402 will move down and maintain a relatively low position, thereby first reducing the luminous brightness of the light strip a at that location, and finally indicating that at least one fastening bolt 13 has fallen at the installation connection structure.

[0065] It should be noted that in the width direction of the ceiling board 11, that is, the inner and outer directions of the ceiling structure, the lifting plate 402 can be on the inner side, directly above or outer side of the light strip a. As long as the lifting plate 402 is vertically close to the light strip a, the latter will have a significant decrease in brightness at this location, thereby indicating that the fastening bolts 13 have fallen off.

[0066] In principle, even if the lifting vertical plate 402 is in the initial state without being pressed down and is much higher than the light strip a, it still has a shading effect on the light strip a, but the shading effect is relatively small at this time.

[0067] A bolt blocking strip 5 is also provided on the upper surface of the ceiling plate 11 for changing the luminous amplitude of the light strip a by blocking the fastening bolts 13 that slide down from the elastic lifting baffle unit 4 .

[0068] In this embodiment, the attached Figure 4 The second way to implement the function of timely discovering the corresponding fastening bolt after it falls requires: first, the fallen fastening bolt 13 hits the inclined plate 301, but cannot stay on the inclined plate 301, but continues to fall downward onto the ceiling plate 11; second, the fallen fastening bolt 13 cannot fall from the ceiling plate 11 to the ground, otherwise it is easy to be lost.

[0069] The first point mentioned above may occur occasionally, but the second point needs to be specially provided, that is, the bolt blocking strip 5 is located further outward than the light strip a, to ensure that the falling or rolling fastening bolts 13 are not easy to cross the bolt blocking strip 5, and then are located near the light strip a, which also plays the role of shading and positioning, and reminding that the fastening bolts 13 have fallen.

[0070] Furthermore, the length of the bolt blocking strip 5 is equal to that of the ceiling panel 11, and the vertical cross-sectional shape of the former is a right triangle with the hypotenuse of the right triangle facing inward, so that the final resting position of the fallen and rolling fastening bolt 13 is as close to the light strip a as possible, making the above-mentioned shading, positioning and prompting effects more obvious, which is very practical.

[0071] An anti-lost baffle 6 for preventing the fastening bolts 13 from sliding off the elastic lifting baffle unit 4 is provided on one side of the mounting plate 12 close to the light strip a.

[0072] In this embodiment, the fallen fastening bolt 13 may slide off the inclined plate 301, and may also slide over the ceiling plate 11 and fall directly to the ground due to the fast sliding speed. This needs to be avoided, which is the role of the anti-loss baffle 6.

[0073] Generally, after the fallen fastening bolt 13 hits the anti-lost baffle 6, its kinetic energy is greatly reduced, and it is difficult to be thrown back and fall on the inner side of the light strip a, which ensures that the above-mentioned shading effect is always effective.

[0074] Furthermore, the vertical plate 101 can be set to be relatively wide, which blocks the fastening bolts 13 thrown out in the reverse direction, and finally makes the fastening bolts 13 fall near the light strip a.

[0075] The plugging rod unit 2 further includes a movable ring 203 which is sleeved on the limiting rod 202 and located above the wall-side perforated plate 201 , and a supporting spring 204 which is arranged on the wall-side perforated plate 201 and is used to support the movable ring 203 .

[0076] In this embodiment, the anti-slip effect of the limit rod 202 on the horizontal plate 102 does not require the former to be elastically raised and lowered, and the movable ring 203 and the support spring 204 cooperate so as to mainly provide a more symmetrical elastic support effect for the inclined plate 301, and further ensure that the inclined plate 301 can only move straight up and down, that is, the limit rod 202 and the lifting vertical plate 402 together elastically support the inclined plate 301 one inside and one outside.

[0077] The difference is that the limit block 403 and the lifting vertical plate 402 are integrally formed, while the movable ring 203 and the limit rod 202 are sleeved. The elastic support function of the former is always effective, while the elastic support function of the latter can be selectively turned off. The specific method is: the movable ring 203 can be manually shifted upward on the limit rod 202, and the upper end of the limit rod 202 leaves the inclined plate 301.

[0078] The perforated inclined plate unit 3 further includes a blocking and silent dual-purpose strip 303 which is arranged on the inclined plate 301 and is used to block the fastening bolts 13 that have fallen off or to press on the elastic lifting baffle unit 4 .

[0079] In this embodiment, when the ceiling structure is initially installed, it is necessary to select the blocking and mute dual-purpose strip 303 to be on the top or on the bottom. During normal use of the ceiling structure, the above-mentioned "blocking" and "mute" functions cannot be switched.

[0080] Among them, the mounting plate 12 and the connecting column 14 are screwed together, and the blocking and silent dual-purpose strip 303 is on top, so it plays a "blocking" function, making it difficult to achieve the second function of the fastening bolt 13 being discovered in time after falling, thereby greatly reducing the probability of the fastening bolt 13 falling directly to the ground.

[0081] If the blocking and silent dual-purpose strip 303 is directly below, it will play a "silent" function, so that the original metal-to-metal method between the inclined plate 301 and the lifting vertical plate 402 is changed to the blocking and silent dual-purpose strip 303 with rubber material in the middle, which greatly reduces the probability of harmful friction noise between metals. This is also very practical. For details, please refer to the attached Fig.10 .

[0082] The upper surface of the ceiling plate 11 is also provided with positioning grooves 7 which are located at both sides of the connecting column 14 and the plug-in rod unit 2 and are used to install the light strip a.

[0083] In this embodiment, the length of the positioning groove 7 is equal to that of the ceiling plate 11, that is, the former is a through groove for stably installing the light strip a.

[0084] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
