[0036] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0037] The following combines Figures 1 to 3 , and describes the embodiments of the present utility model.

[0038] In the related art, most of the anti-cracking measures for existing conventional suspended ceilings are for traditional building suspended ceilings and are not fully applicable to the suspended ceiling installation of steel structure modular buildings. For example, some methods improve the crack resistance of the suspended ceiling by increasing the thickness of the suspended ceiling module or using special materials. This method not only increases the weight and cost of the suspended ceiling, which is not conducive to the lightweight and cost control of modular buildings, but also cannot effectively eliminate the height difference at the joint position.

[0039] In addition, in the related art, during the long-term use of the suspended ceiling module, due to factors such as temperature change and humidity change, the height of the joint position is likely to change and cracking occurs.

[0040] According to an embodiment of the present utility model, on the one hand, a ceiling structure is provided, which is applied to a steel structure modular building and includes: a box body 1, a connection component 2, a keel frame 3, and a first hanging plate 4. The box body 1 is adapted to be connected to the indoor top, and a splicing position is formed at the connection position of two adjacent box bodies 1. The connection component 2 includes a guiding structure 201 and an adjusting structure 202. The adjusting structure 202 is movably arranged along the vertical direction on the guiding structure 201. The adjusting structure 202 has an unlocking state in which it can move along the guiding structure 201 and a locking state in which it is fixed to the guiding structure 201. The keel frames 3 are arranged in one-to-one correspondence with the box bodies 1. The keel frames 3 are connected to the corresponding box bodies 1 through a plurality of connection components 2. The keel frames 3 are assembled and connected with the adjusting structure 202 and adjust their own heights as the adjusting structure 202 moves. The first hanging plate 4 is arranged at the bottom of the keel frame 3. The first hanging plate 4 includes a first splicing plate 401 and a first covering plate 402. The first splicing plate 401 is arranged corresponding to the splicing position. Both sides of the first splicing plate 401 are connected to the first covering plate 402. The first covering plate 402 is arranged corresponding to the bottom surface of the box body 1.

[0041] Applying the ceiling structure of this embodiment, the box body 1 and the keel frame 3 are connected through the connection component 2. After the adjacent box bodies 1 and the corresponding keel frames 3 are installed, the height of the keel frame 3 can be adjusted by changing the position of the adjusting structure 202 on the guiding structure 201. Through this fine-tuning operation, the heights at the corresponding splicing positions of the adjacent keel frames 3 tend to be consistent, ensuring the flatness and stability of the ceiling bottom surface. Then, the first splicing plate 401 is installed at the position of the keel frame 3 corresponding to the splicing position. The integrated first splicing plate 401 can further fix the splicing position, improving the reliability at the splicing position while also preventing the joint between the first splicing plate 401 and the first covering plate 402 from coinciding with the splicing position, further reducing the risk of cracking, and effectively solving the problem of poor flatness at the splicing position of the existing ceiling modules.

[0042] Specifically, the connection component 2 is in a point-like connection. Compared with increasing the overall thickness of the ceiling module, the structure of the connection component 2 is simpler and easier to manufacture, and the overall weight is also lighter. At the same time, the height of the keel frame 3 can be flexibly adjusted according to requirements.

[0043] Furthermore, the box body 1, the connection component 2, and the keel frame 3 are all metal components, which are less affected by factors such as temperature change and humidity change, are not easily deformed, and can thus effectively prevent the misalignment and cracking of the splicing positions.

[0044] In this embodiment, the guiding structure 201 includes a connecting seat 2011 and a guiding rod 2012. The guiding rod 2012 extends vertically, and the adjusting structure 202 is sleeved on the guiding rod 2012. The guiding rod 2012 is connected to the box body 1 through the connecting seat 2011. The structure is simple and reliable, which is convenient for processing and manufacturing. Since it is difficult to directly install the guiding rod 2012 on the box body 1, the setting of the connecting seat 2011 can facilitate the installation of the guiding rod 2012.

[0045] Among them, the matching manner between the guiding rod 2012 and the adjusting structure 202 is not limited. The guiding rod 2012 can be a screw rod while the adjusting structure 202 is a nut. The guiding rod 2012 can be a smooth rod body while the adjusting structure 202 is a positioning sleeve with a positioning pin. Through the insertion and positioning of the positioning pin, it can be flexibly selected according to requirements.

[0046] In addition, the relative movement manner between the guiding rod 2012 and the adjusting structure 202 is not limited. The adjusting structure 202 can be directly sleeved on the guiding rod 2012, or the adjusting structure 202 can also cooperate with the guide rail arranged on the guiding rod 2012 through its own slider.

[0047] In this embodiment, the box body 1 includes a main body 101 and secondary beams 102. The secondary beams 102 extend along a preset direction and are arranged inside the main body 101. The connecting seat 2011 is assembled and connected to both the main body 101 and the secondary beam 102 through fastening components 103. The structural strength of the local position where the main body 101 is connected to the secondary beam 102 is relatively high, and this position can more stably and reliably bear the connecting seat 2011.

[0048] Among them, the secondary beam 102 is a structural member that strengthens the inside of the main body 101. A plurality of secondary beams 102 are arranged at intervals inside the main body 101, and each connecting seat 2011 is connected to the corresponding position of the secondary beam 102;

[0049] In addition, the specific type and structure of the secondary beam 102 are not limited. It can be a rod-shaped structure, or structural members such as channel steel and I-beam, which can be selected according to requirements.

[0050] Preferably, the fastening component 103 is a connecting screw. The connecting screw sequentially passes through the connecting seat 2011, the main body 101, and the secondary beam 102 from bottom to top, and fixedly connects the three.

[0051] In this embodiment, the outer wall of the guiding rod 2012 is provided with threads. The adjusting structure 202 includes at least two adjusting nuts that cooperate with the guiding rod 2012. The matching manner is simple and reliable. After the adjusting structure 202 of this form is assembled with the guiding rod 2012, the adjustment process of the adjusting structure 202 is more convenient and rapid.

[0052] Among them, it should be noted that, such as Figure 1 andFigure 3 As shown, a matching structure is provided at the corresponding position of the keel frame 3. A through hole that is penetrated and matched with the guide rod 2012 is provided on the matching structure. One part of the adjusting nut of the adjusting structure 202 is located on the upper side of the matching structure, and the other part of the adjusting nut of the adjusting structure 202 is located on the lower side of the matching structure. By tightening the adjusting nuts on the upper and lower sides, the position of the matching structure is restricted.

[0053] In this embodiment, the connecting seat 2011 includes a first transverse section 20111, a vertical section 20112, and a second transverse section 20113 that are connected in sequence from top to bottom along the vertical direction. The first transverse section 20111 is connected to the box body 1, and the second transverse section 20113 is connected to the guide rod 2012. The connecting seat 2011 in this form can form an installation position on the second transverse section 20113, which can more conveniently supply the guide rod 2012 for installation. The overall structure is simple and reliable, and it is convenient for processing and manufacturing.

[0054] Specifically, as Figure 3 shown, the connecting seat 2011 is arranged in a Z shape.

[0055] In this embodiment, an abutting member 2013 is provided at the upper end of the guide rod 2012. A through hole for the guide rod 2012 to pass through is provided on the second transverse section 20113. The guide rod 2012 is adapted to pass through the through hole from top to bottom and make the abutting member 2013 abut against the upper end surface of the second transverse section 20113. The guiding structure 201 further includes a fixing nut 203. The guide rod 2012 is assembled and fixed to the second transverse section 20113 through the fixing nut 203. The matching method is simple and reliable. The guide rod 2012 can be fixed to the second transverse section 20113 by the cooperation of the abutting member 2013 and the fixing nut 203. The guide rod 2012 and the connecting seat 2011 are detachably assembled, occupying less space during part transportation and being convenient for maintenance and replacement.

[0056] It can be understood that as an alternative embodiment, the guide rod 2012 can also be connected to the second transverse section 20113 by fixing forms such as welding.

[0057] Specifically, each component in the ceiling structure of this embodiment can be precisely processed and assembled in the factory, effectively ensuring the manufacturing accuracy and improving the overall quality of the ceiling.

[0058] In this embodiment, the ceiling structure further includes a second suspension plate 5 provided on the bottom surface of the first suspension plate 4. The second suspension plate 5 can further improve the structural strength and flatness of the first suspension plate 4.

[0059] In this embodiment, the second suspension plate 5 includes a second splicing plate 501 and a second covering plate 502. The second splicing plate 501 is correspondingly arranged with the splicing position. Both sides of the second splicing plate 501 are connected to the second covering plate 502. The first splicing plate 401 and the first covering plate 402 are connected to form a first joint 403, and the second splicing plate 501 and the second covering plate 502 are connected to form a second joint 503. The second joint 503 is arranged in a staggered manner with the first joint 403. By setting the joint positions of the two suspension plates in this way, when the second joint 503 corresponds to the first joint 403, the stress concentration phenomenon caused by temperature change or humidity change can be effectively avoided, so that the two joint positions do not crack simultaneously, thereby greatly reducing the risk of ceiling cracking and improving the service life and safety of the ceiling.

[0060] In this embodiment, the width of the second splicing plate 501 is greater than that of the first splicing plate 401. The second splicing plate 501 can cover the first joint 403 and can play a role in supporting and connecting the first joint 403.

[0061] Specifically, the width range of the first splicing plate 401 is 550 mm to 650 mm; the width range of the second splicing plate 501 is 1150 mm to 1250 mm.

[0062] Preferably, the width of the first splicing plate 401 is 600 mm, and the width of the second splicing plate 501 is 1200 mm.

[0063] In addition, due to the provision of the first splicing plate 401 and the second splicing plate 501, when it is necessary to adjust the height of the keel frame 3, the first splicing plate 401 and the second splicing plate 501 can be removed, and the adjustment can be quickly carried out without removing a relatively large board surface to achieve the adjustment process.

[0064] In this embodiment, the first suspension plate 4 is a flame-retardant board, and the second suspension plate 5 is a gypsum board. The first suspension plate 4 in this form has higher safety.

[0065] Preferably, the first suspension plate 4 is a wooden flame-retardant board. The first suspension plate 4 in this form has better toughness and is not prone to brittle fracture. At the same time, when the first suspension plate 4 is connected to the keel frame 3 through connectors, it is not prone to wire breakage.

[0066] In this embodiment, the ceiling structure further includes a splicing keel 6. The splicing keel 6 is correspondingly arranged with the splicing position. Adjacent keel frames 3 are assembled and connected through the splicing keel 6. After the heights of adjacent keel frames 3 are adjusted to be flat, the splicing keel 6 can more firmly and stably connect the two sides of the keel frames 3, improving the integrity at the splicing position of adjacent keel frames 3 and avoiding joint cracking.

[0067] It should be noted that the entire leveling process of the ceiling structure in this embodiment does not require complex equipment or tools. At the same time, the ceiling structure can be assembled only by simple welding and laying, and the installation process is fast and efficient, reducing the construction difficulty and cost.

[0068] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
