[0010] Beneficial effects: By setting the connecting parts to abut the two sides of the rectangular crossbeam respectively, the two side walls of the groove can hold the crossbeam, and the bottom surface of the positioning part can abut the top surface of the crossbeam, that is, the side wall of the groove and the top surface abut the crossbeam, so that the lifting part and the crossbeam are fixed in three directions to limit the relative rotation between the lifting part and the crossbeam, keep the relative fixation, and improve the stability of the lifting lug.

[0011] In an alternative embodiment, the connecting part extends along the side wall of the crossbeam and is at least partially located below the crossbeam, and the lifting lug is connected with the outer wall of the connecting part.

[0012] Beneficial effects: When the connecting part abuts the crossbeam, the abutting surface between the connecting part and the crossbeam along the side wall of the crossbeam is as large as possible, which reduces the shaking caused by deformation and other factors, and further improves the stability of the structure.

[0013] In an alternative embodiment, the lifting part further comprises a reinforcing part, which is located above the lifting lug and connected with the connecting part and the lifting lug respectively.

[0014] Beneficial effects: The reinforcing part is connected with the connecting part and the lifting lug respectively, which effectively improves the structural strength of the lifting lug and facilitates the installation and fixation of the top plate.

[0017] In an alternative embodiment, the lifting lug extends in a direction away from the crossbeam.

[0018] Beneficial effects: The lifting lug extends in a direction away from the crossbeam, so that the distance between the lifting lugs on the two sides of the same crossbeam increases when installed, which increases the force bearing area of the top plate and the distance between adjacent suspended ceiling structures, reduces the number of suspended ceiling structures within the effective length range, improves the reliability of the suspended ceiling while saving cost.

[0019] In an alternative embodiment, the bottom of the lifting lug has a mounting surface for abutting the top plate, and the mounting surface is horizontally arranged.

[0020] Beneficial effects: The mounting surface is horizontally arranged and used for mounting the top plate, so that the top plate can be arranged to fit the mounting surface when installed, which increases the contact area with the top plate and limits the top plate to a certain extent to keep the top plate horizontal.

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical scheme in the embodiments of the utility model. Obviously, the described embodiments are some embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0032] In the related art, during the traditional decoration construction, the ceiling is usually installed by using the suspended ceiling joist and the top frame. During the construction process of the structure, the top frame needs to be installed first, then the joist is fixed on the top frame respectively and leveling treatment is performed, and then the ceiling is installed on the joist. The construction method is complicated in steps, and the leveling construction of the joist is difficult, and therefore it is necessary to propose a suspended ceiling structure and a suspended ceiling system in view of the above problems.

[0033] The embodiments of the present application will be described below in combination with Figures 1 to 3

[0034] According to the embodiments of the present application, on the one hand, a suspended ceiling structure is provided, which comprises a cross beam 1 and a hoisting piece 2. The two ends of the cross beam 1 are respectively used for connecting side walls. The hoisting piece 2 has a matching position for assembling with the cross beam 1. The hoisting piece 2 is placed on the cross beam 1 from top to bottom through the matching position thereof. The hoisting piece 2 is located on both sides of the cross beam 1 to form a lifting lug 202. At least a part of the lifting lug 202 is lower than the cross beam 1 and is used for connecting a top plate.

[0035] In the application of the suspended ceiling structure, the hoisting piece 2 is assembled on the cross beam 1. The hoisting piece 2 is of a whole structure. In the construction process, the hoisting piece 2 can be directly placed on the cross beam 1 by using the matching position thereof. The assembling method of the hoisting piece 2 and the cross beam 1 is simple and reliable. The two can be connected through a single fixing and connecting step. In addition, since the hoisting piece 2 has the lifting lug 202 which is lower than the cross beam 1, the top plate can be directly connected to the lower side of the cross beam 1 through the lifting lug 202. The assembling and construction steps are reduced, time and labor are saved, and the problem of complicated construction process of the joist is effectively solved.

[0036] Wherein, the up refers to the direction of the arrow in the figure, and the down refers to the direction of the arrow in the figure. Figure 1 Figure 1

[0037] It should be noted that the cross beam 1 is a beam for bearing the hoisting piece 2 between the two side walls. The two ends thereof are respectively connected and fixed with the side walls. The cross beam 1 can be arranged between the opposite two side walls or between the adjacent two side walls.

[0038] Optionally, the connecting method between the cross beam 1 and the side wall includes but is not limited to shaft hole connection, bolt connection, buckle connection, etc.

[0039] Similarly, the shape of the cross beam 1 has various settings. The cross beam 1 can be a hollow pipe or a solid column. The cross section thereof can be but is not limited to rectangular, circular, etc. It can be flexibly selected according to the requirements.

[0040] ​​​It should be noted that the matching position is arranged on the lifting piece 2 for assembling and fixing with the cross beam 1. It can be understood that the matching position has a structure capable of being connected and fixed with the cross beam 1, and the structure can be connected and fixed with the cross beam 1 in the manner of, but not limited to, clamping and welding.

[0041] In addition, the lifting piece 2 is placed on the cross beam 1 from top to bottom and has a lifting lug 202 on both sides of the cross beam 1, that is, the lifting piece 2 should have a structure arranged to extend downward on both sides of the cross beam 1 to be fixed on the cross beam 1 in a manner of semi-enclosing the cross beam 1.

[0042] In addition, the lifting lug 202 is arranged at least partially below the cross beam 1 to avoid affecting the suspended ceiling structure itself when the top plate is fixed on the lifting lug 202, and the structure can leave part of the operation space for the installation of the top plate, facilitating assembly.

[0043] Further, the lifting lug 202 on the lifting piece 2 is used to fix the top plate, so the lifting lug 202 should be arranged to extend along the axial direction of the cross beam 1 or be distributed at intervals to fix the top plate in the axial direction of the cross beam 1.

[0044] It is easy to understand that the lifting piece 2 and the cross beam 1 in the suspended ceiling structure can be prefabricated components, that is, the lifting piece 2 is assembled on the cross beam 1 first, and then the suspended ceiling structure is installed on the side wall through the cross beam 1, or the cross beam 1 is installed on the side wall first, and then the lifting piece 2 is assembled and fixed on the cross beam 1.

[0045] In one embodiment, the lifting piece 2 has a downwardly open groove 201, the groove 201 forms a matching position and extends along the axial direction of the cross beam 1, and the groove 201 is sleeved on the cross beam 1. In this way, the groove 201 is used to form the matching position and is sleeved on the cross beam 1, so that the lifting piece 2 is more stable when placed on the cross beam 1, and the structure is simple and stable, improving the reliability of the suspended ceiling structure.

[0046] It should be noted that the groove 201 is open downward and is sleeved on the cross beam 1, and the top cover of the groove 201 is on the top surface of the cross beam 1, that is, the lifting piece 2 is suspended on the cross beam 1 through the groove 201.

[0047] In addition, the axial direction of the cross beam 1 is the direction from one end to the other end of the cross beam 1 assembled on the side wall, and the groove 201 extends along the axial direction of the cross beam 1, that is, the groove 201 is long strip-shaped and can cover the top surface and the side surface of the cross beam 1.

[0048] Further, the groove 201 has openings at both ends of the cross beam 1, respectively, for the cross beam 1 to pass through, so that the groove 201 can cover the top surface and the side surface of the cross beam 1.

[0049] In one embodiment, the beam 1 is a rectangular bar, the groove top of the groove 201 forms a positioning part 2011, the bottom surface of the positioning part 2011 forms a positioning surface for cooperating with the top surface of the beam 1, and the side wall of the groove 201 forms a connecting part 2012, and the connecting parts 2012 on both sides are respectively in abutting cooperation with the side walls of the beam 1. In this way, by arranging the connecting parts 2012 to be in abutting cooperation with the side walls of the beam 1 on both sides of the rectangular beam 1, the two side walls of the groove 201 can clamp the beam 1, and the bottom surface of the positioning part 2011 cooperates with the top surface of the beam 1, that is, the side wall and the top surface of the groove 201 are in abutting cooperation with the beam 1, so that the lifting part 2 and the beam 1 are fixed in three directions to limit the relative rotation between the lifting part 2 and the beam 1, keep the relative fixation, and improve the stability of the lifting lug 202.

[0050] It should be noted that the rectangular bar means that the cross section of the beam 1 is rectangular, which is used for cooperating with the groove top and the side wall of the groove 201.

[0051] In addition, the groove top of the groove 201 is used as the positioning part 2011, so the groove top surface of the groove 201 is the positioning surface, and the positioning part 2011 should at least cover the top surface of the beam 1 so that the positioning surface cooperates with the top surface of the beam 1.

[0052] Further, the positioning surface cooperates with the top surface of the beam 1 means that the positioning surface is in close contact with the top surface of the beam 1.

[0053] Further, the side wall of the groove 201 is used as the connecting part 2012, and the connecting parts 2012 on both sides are in abutting cooperation with the side walls of the beam 1, so that the positioning surface is in close contact with the top surface of the beam 1 while limiting the relative displacement of the two, and the lifting part 2 is positioned and fixed.

[0054] It is easy to understand that the connecting parts 2012 on both sides clamp the two sides of the rectangular bar respectively, and the positioning surface is in close contact with the top surface of the rectangular bar, so that the lifting part 2 and the beam 1 are fixed to each other, and the lifting lug 202 is prevented from shaking.

[0055] In one embodiment, the connecting part 2012 is arranged along the side wall of the beam 1 and at least partially located below the beam 1, and the lifting lug 202 is connected with the outer wall of the connecting part 2012. When the connecting part 2012 of this structure is in abutting cooperation with the beam 1, it can increase the abutting surface between the connecting part 2012 and the beam 1 along the side wall of the beam 1 as much as possible, reduce the shaking caused by factors such as deformation, and further improve the stability of the structure.

[0056] It should be noted that the part of the connecting part 2012 located below the beam 1 is used for connecting with the lifting lug 202, which can ensure that the lifting lug 202 is located below the beam 1, and on the other hand, it can reserve space for the assembly of the lifting lug 202 and the top plate, facilitating the assembly of the top plate.

[0057] In addition, the outer wall of the connecting portion 2012 is the side of the connecting portion 2012 facing away from the cross beam 1, and the lug 202 is connected to the side of the connecting portion 2012 facing away from the cross beam 1, so that the position of the lug 202 avoids the notch position of the groove 201 and does not affect the normal assembly of the hoisting piece 2 and the cross beam 1.

[0058] In one embodiment, the hoisting piece 2 further comprises a reinforcing portion 203, which is located above the lug 202 and connected to the connecting portion 2012 and the lug 202, respectively. By arranging the reinforcing portion 203 to be connected to the connecting portion 2012 and the lug 202, respectively, the structural strength of the lug 202 is effectively improved, facilitating the installation and fixation of the top plate.

[0059] It should be noted that the reinforcing portion 203 is a component connected to the lug 202 and further fastens the lug 202. As can be easily understood, when the lug 202 is provided with a top plate, the lug 202 will be subjected to a downward force from the top plate. Therefore, the arrangement of the reinforcing portion 203 can generate a lifting force on the lug 202, avoiding deformation of the lug 202 due to its own strength or time, and improving the safety of the device.

[0060] The reinforcing portion 203 can have various structures, including but not limited to a plate shape and a strip shape.

[0061] In one embodiment, the reinforcing portion 203 comprises a plurality of reinforcing plates, which are arranged axially along the cross beam 1. By arranging a plurality of reinforcing plates to be arranged according to the specific position of the top plate installed on the lug 202, the strength of the lug 202 is improved while the material cost is saved.

[0062] It should be noted that the reinforcing plates are arranged perpendicular to the axial direction of the cross beam 1 and are connected to the lug 202 and the connecting portion 2012, respectively, to fasten and limit the lug 202.

[0063] The reinforcing plates are connected to the lug 202 at the position where the lug 202 is assembled with the top plate, so as to as far as possible to improve the strength of the lug 202 and offset the gravity of the top plate acting on the lug 202.

[0064] In one embodiment, the lug 202 extends in a direction away from the cross beam 1. Such a structure increases the distance between the lugs 202 on both sides of the same cross beam 1 during installation, increases the force bearing area of the top plate, and increases the distance between adjacent suspended ceiling structures, thereby reducing the number of suspended ceiling structures within the effective length range, improving the reliability of the suspended ceiling while saving costs.

[0065] It should be noted that the lifting lug 202 extends away from the cross beam 1, that is, the position of the lifting lug 202 where the top plate is assembled is away from the cross beam 1, so that the distance between the positions of the lifting lug 202 on the same cross beam 1 where the top plate is assembled is increased, so that the top plate is more uniform in stress after assembly, prolonging the service life.

[0066] It is easy to understand that the position on the top plate matched with the lifting lug 202 should be spaced from the reserved part, so that the assembly position of the top plate is uniformly distributed on the top plate, so that the top plate is uniformly stressed after assembly.

[0067] In one embodiment, the bottom of the lifting lug 202 has a mounting surface for matching with the top plate, and the mounting surface is horizontally arranged. The mounting surface is horizontally arranged and used for mounting the top plate, so that the top plate can be arranged to fit the mounting surface during installation, increasing the contact area with the top plate, and the top plate can be limited to a certain extent, so that the top plate remains horizontal.

[0068] It should be noted that the mounting surface is the bottom surface of the lifting lug 202 to ensure the stability of the installation of the top plate.

[0069] The horizontally arranged mounting surface can enable the top plate to be assembled by fitting the mounting surface during installation, without the need for separate leveling of the top plate, thereby improving installation efficiency.

[0070] In one embodiment, the mounting surfaces on both sides of the cross beam 1 are located in the same plane. In this way, the mounting surfaces on both sides of the cross beam 1 do not need to be leveled during installation, and the top plate can be directly matched and fixed with the mounting surface, reducing the construction steps and saving manpower and resources.

[0071] It should be noted that the mounting surfaces on both sides of the same cross beam 1 are horizontally arranged and located in the same plane, so that the lifting member 2 can be installed on the cross beam 1 from top to bottom, and the mounting surfaces on both sides of the cross beam 1 can be automatically leveled without the need for re-leveling, thereby saving manpower and resources.

[0072] According to the embodiments of the present application, on the other hand, a suspended ceiling system is also provided, comprising: a top plate and the above-mentioned suspended ceiling structure, and a plurality of suspended ceiling structures are arranged at intervals.

[0073] The suspended ceiling system of the present embodiment uses the above-mentioned suspended ceiling structure, and during installation, only the installation height of the plurality of cross beams 1 needs to be kept the same, so that the mounting surfaces of the lifting lugs 202 on each cross beam 1 are located in the same horizontal plane, without the need for additional leveling operation, thereby improving the construction efficiency and saving manpower and resources.

[0074] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the appended claims.
