The suspended ceiling is a common structure in building interior decoration, not only can beautify the indoor environment, but also can create a colorful indoor space artistic image. As shown in fig. 1, in the related art, a suspended ceiling 01 includes a plurality of main runners 02, a runner skeleton formed in an inverted U shape is erected on the plurality of main runners 02, and a secondary runner 03 vertically connected to the main runners 02 and a plurality of panels 04 attached to the secondary runner 03 are sequentially installed inside the runner skeleton, so that the plurality of panels 04 surround a light trough 05.

Wherein, light trough 05 can regard as a decoration molding of furred ceiling 01 to improve furred ceiling 01's interior decoration effect. In addition, decorative lamps such as lamp tubes or lamp strips can be installed in the lamp groove 05 to improve indoor light rendering effect. However, in the light trough structure of the suspended ceiling 01, a keel frame including a plurality of main keels 02 and a plurality of cross keels 03 needs to be previously installed in a contour direction of the light trough 05. Consequently, the main joist 02 and the secondary joist 03 that can use a large amount of that set up of fossil fragments skeleton to make this furred ceiling 01's light trough structure more complicated, can reduce the preparation installation rate of light trough structure.

In order to solve the above problems, it is necessary to simplify the structure of the lamp vessel. Based on this, as shown in fig. 2, embodiments of the present application provide a suspended ceiling 100 mounted adjacent to a roof structure 200. The suspended ceiling 100 includes a troffer structure 10. The troffer structure 10 includes a plurality of first panels 11, a second panel 12, and a plurality of troffer connection assemblies 13. The first panels 11 are divided into two groups, the second panels 12 are respectively connected with the two groups of first panels 11 and enclose a lamp trough 14 with a downward opening, and the openings of the second panels 12 and the lamp trough 14 are arranged oppositely.

With continued reference to fig. 2, the two sets of first panels 11 are distributed in the left-right direction. Correspondingly, a plurality of light trough coupling assembling 13 divide into two sets ofly equally, and the upper end of every group first panel 11 is connected with a set of light trough coupling assembling 13's lower extreme, and light trough coupling assembling 13's upper end all is connected with top structure 200. In this way, the first panels 11 are connected to the top structure 200 through the light trough connecting assemblies 13 to fixedly mount the light trough 14.

Compared with the prior art, the light trough structure 10 provided by the embodiment of the application does not need to set up a keel frame along the outline of the light trough 14. Therefore, the material and the workload for erecting the keel framework are saved, the light trough structure 10 is simpler, the installation operation difficulty of the light trough structure 10 is reduced, and the installation is more convenient. Meanwhile, the installation speed of the light trough structure 10 is improved, and the manufacturing and installation cost of the light trough structure 10 is reduced.

Wherein, the upper end surfaces of the two groups of first panels 11 distributed at the left and right can be flush with the upper side surface of the second panel 12. The upper end surfaces of the two sets of first panels 11 may be attached to the lower side surface of the second panel 12. It is also possible to project the upper ends of the two sets of first panels 11 upwardly above the upper side of the second panel 12. A downwardly opening troffer 14 may be formed. The second panel 12 may be in contact with or even attached to the top structure 200, or may be spaced from the top structure 200.

Illustratively, as shown in fig. 2. First, one set of the first panel 11, the second panel 12 and the other set of the first panel 11 may be sequentially and vertically connected by steel nails or screws to form the light trough 14. In this case, the two sets of first panels 11 are two side walls of the lamp trough 14, and the second panels 12 are bottom walls of the lamp trough 14. Subsequently, two outer side surfaces of the two sets of first panels 11 away from each other are directly and fixedly connected with the top structure 200 through the two sets of light trough connecting assemblies 13, respectively, to form the light trough structure 10.

Alternatively, the two sets of first panels 11 may be first fixedly mounted, and then the second panels 12 may be connected between the two sets of first panels 11 to form the light trough 14.

With continued reference to fig. 2, in the process of connecting the first panel 11 and the light trough connecting assemblies 13, one set of light trough connecting assemblies 13 is connected to the left side surfaces of the left set of first panels 11, and the other set of light trough connecting assemblies 13 is connected to the right side surfaces of the right set of first panels 11. So, the direction of insertion of the screw of connecting light trough coupling assembling 13 and first panel 11 is on a parallel with top structure 200, can avoid top structure 200 to influence the connection operation of light trough coupling assembling 13 and first panel 11, installation convenient and fast.

Further, in the case where the second panel 12 is connected between the two sets of first panels 11, the chute connection assembly 13 may also be connected to the upper end faces of the two sets of first panels 11. And is not limited herein.

In some embodiments, the first panel 11 and the second panel 12 may be any one of a wood board, a metal board, or a plastic board. Because the nail-holding force between the plate and the steel nail or the screw is good, the screw or the steel nail is not easy to loosen, and the plate has high structural strength, which is beneficial to improving the structural strength of the light trough structure 10.

Therefore, the light trough structure 10 is manufactured by the first panel 11 and the second panel 12, and the first panel 11 and the second panel 12 have high structural strength and good nail holding force with a steel nail or a screw, that is, the first panel 11 and the second panel 12 can be used as part of the stress structure of the light trough structure 10, which is beneficial to simplifying the structure of the light trough structure 10.

In addition, the first panel 11 and the second panel 12 may also be a glass mat faced high strength fiber gypsum board, including a gypsum board base layer in the middle, and a glass fiber facing layer (i.e., a glass mat facing) that is in intimate contact with opposite sides of the gypsum board. The channel structure 10 has a higher fire resistance limit due to the use of glass mat-faced high strength gypsum boards having fire resistance of class a as the first panel 11 and the second panel 12. Moreover, the structural strength of the gypsum board can be improved through the double-layer glass felt surface, so that the gypsum board is not easy to crack. In addition, glass fibers may also be filled in the gypsum board base layer to increase the structural strength of the gypsum base layer.

So, can make the holding power between glass felt face high strength fiber gypsum board and steel nail or the screw better, screw or steel nail are difficult for the pine to take off promptly, and panel itself has higher structural strength. In the up-down and left-right directions, the light trough structure 10 made of a plurality of glass-felt-surface high-strength fiber gypsum boards is nailed, so that the first panel 11 and the second panel 12 can bear the whole mass load of the light trough structure 10, and the whole structural strength of the light trough structure 10 is improved.

Illustratively, as shown in fig. 2, in the case where the second panel 12 is located between two sets of the first panels 11. When connecting first panel 11 and second panel 12, use steel nail or screw to insert first panel 11 and the right-hand member (the left end) of second panel 12 from right left (or from left right) in proper order to realize being connected of first panel 11 and second panel 12, the installation is simple convenient. Since the second panel 12 generally bears the gravity from top to bottom, the screws or steel nails transversely arranged from left to right have better bearing capacity for the second panel 12. However, the left and right ends of the second panel 12 may be bonded to the first panel 11, but are not limited thereto.

In some embodiments, referring to fig. 3, the troffer connector assembly 13 includes a troffer connector 131 and a troffer fastener 132, and the troffer connector 131 includes a first connector plate 1311 and a second connector plate 1312 that are vertically connected.

As shown in fig. 3, in the set of the chute connection assemblies 13 located on the left side of the chute 14, the first connection plate 1311 is connected to the left side surface of the first panel 11 on the left side. As can be seen from fig. 2 and 3, in the corresponding set of the light trough connecting assemblies 13 located on the right side of the light trough 14, the first connecting plate 1311 is connected to the right side surface of the first panel 11 on the right side.

The first connection plate 1311 and the first panel 11 may be connected by bonding, or the first panel 11 and the first connection plate 1311 may be directly connected by screws. For example, the first connection plate 1311 may be mounted in contact with the first panel 11, and a cushion layer may be placed between the first connection plate 1311 and the first panel 11, which is not limited herein. For the first connecting member 131, if the first panel 11 is perpendicular to the top structure 200, since the first connecting plate 1311 is perpendicular to the second connecting plate 1312, the first connecting plate 1311 can be attached to the first panel 11, and the second connecting plate 1322 can also be attached to the top structure 200. The angle between the first connecting plate 1311 and the second connecting plate 1312 may be an acute angle or an obtuse angle. Since the roof structure 200 may be a floor slab located above the room, it may also be a roof beam located above the room. The floor and the top beam can be of reinforced concrete structure, wood structure or steel structure. And is not limited herein.

And the second coupling plate 1312 is coupled to the top structure 200 by the troffer fasteners 132. The roof structure 200 is generally a reinforced concrete structure, and thus, the light trough fastening member 132 is fixed to the positioning hole of the roof structure 200 by the expansion sleeve structure.

Illustratively, as shown in FIG. 4, the troffer fastener 132 includes a troffer hanger 1321 and a troffer expansion sleeve 1322. The upper end of the lamp slot suspender 1321 is provided with a lamp slot protruding structure 1323, the lamp slot expansion sleeve 1322 is sleeved on the lamp slot suspender 1321, and the lamp slot suspender 1321 is further provided with an external thread. Then, the upper end of the lamp slot suspender 1321 provided with the lamp slot expansion sleeve 1322 is inserted into the positioning hole, and the nut below the lamp slot expansion sleeve 1322 is screwed, so that the lamp slot projection structure 1323 approaches and is squeezed into the lamp slot expansion sleeve 1322 from the upper end of the lamp slot expansion sleeve 1322, and the upper end of the lamp slot expansion sleeve 1322 is expanded in the positioning hole, so that the upper end of the lamp slot suspender 1321 is squeezed and fixed in the positioning hole. Two nuts are further arranged at the lower end of the lamp slot suspender 1321, the second connecting plate 1312 is located between the two nuts, and the second connecting plate 1312 can be fixed to the lamp slot suspender 1321 at any height by screwing the two nuts, so that the fixed height of the lamp slot connecting piece 131 can be flexibly adjusted.

The light trough hanger 1321 may be a lead screw, among others. Correspondingly, a cone-shaped nut is connected to the upper end of the screw rod to serve as a lamp slot projection structure 1323, the diameter of the upper end of the cone-shaped nut is larger than that of the lower end of the cone-shaped nut, the cone-shaped nut can also be used for blocking the lamp slot expansion sleeve 1322, and the lamp slot expansion sleeve 1322 is enabled to expand in the positioning hole, so that the upper end of the lamp slot suspender 1321 is fixed in the positioning hole in an extruding mode. The nuts used to fasten the second connecting plate 1312 may be three, four or more, so that the second connecting plate 1312 may be fastened more firmly by more nuts.

In addition, the lamp slot fastening member 132 may be an expansion bolt or a screw with an expansion sleeve, so that the upper end of the lamp slot connecting member 131 is installed in the positioning hole of the top structure 200 through the expansion bolt or the screw with the expansion sleeve, which is beneficial to reducing the distance between the lamp slot connecting member 131 and the top structure 200.

When the top structure 200 is a wood structure or a steel structure, the socket fastening member 132 may be a screw or a bolt-nut structure, and is directly and fixedly connected with the positioning hole of the top structure 200. The troffer fasteners 132 may also be welded directly to the top structure 200 if the top structure 200 is steel.

In some embodiments, as shown in FIG. 5, FIG. 5 is a right side view of the troffer structure 10 shown in FIG. 2. Therefore, the set of first panels 11 on the right side shown in fig. 2 is two in number and distributed in the front-rear direction in fig. 5.

To couple and secure the first panel 11 under the top coupling structure 200. The set of light trough connecting assemblies 13 on the left side of fig. 2 and the set of first panels 11 on the left side are correspondingly arranged.

Since the plurality of light trough connectors 131 are arranged at intervals in the front-rear direction, the light trough connectors 131 do not need to be arranged continuously, and the light trough connectors 131 arranged at intervals are beneficial to reducing the material consumption of the light trough 14 when the first panel 11 is connected with the top structure 200.

Wherein the first panels 11 in each group may also be one, three, four, five or even more. If the first panels 11 are provided in two sets disposed left and right, the size and number of the second panels 12 are the same as those of the first panels 11 of one set. Each first panel 11 may also be connected to three, four, five or even more troffer connectors 131.

Illustratively, along fore-and-aft direction, the width of light trough connecting piece 131 is 2 ~ 5cm, and simple structure is small and exquisite. Thus, each of the troffer connectors 131 is typically connected to the top structure 200 by one of the troffer fasteners 132, which facilitates installation and saves material. In addition, in order to increase the stability of the connection of each of the socket connection assemblies 13, it is also possible to provide that each of the socket connection members 131 is connected to two, three or more of the socket fasteners 132.

In other embodiments, as shown in fig. 6, the light trough connecting member 131 may be a long keel, and the length of the light trough connecting member 131 is arranged along the front-back direction and is connected to the group of first panels 11. At this time, the number of the light trough fastening members 132 in each set of the light trough connecting assembly 13 is plural, and the plural light trough fastening members 132 are also distributed at intervals along the front-rear direction, so as to fixedly connect the keel-like light trough connecting member 131 below the roof structure 200.

Wherein each set of first panels 11 may be connected to the roof structure by means of a keel-like light trough connector 131. If the length of each group of first panels 11 in the front-back direction is much greater than the length of the keel-like light trough connectors 131, at this time, each group of light trough connectors 13 includes a plurality of keel-like light trough connectors 131, each group of first panels 11 sequentially connects the plurality of keel-like light trough connectors 131 in the front-back direction, and each keel-like light trough connector 131 is connected with the top structure 200 through a plurality of light trough fasteners 132.

In addition, in the case that the light trough 14 has a box-shaped structure with an opening at one side, the keel-shaped light trough connectors 131 may be a curved structure, and at least three groups of the first panels 11 on the side wall of the light trough 14 are all connected with the top structure 200 through one curved light trough connector 131. At this time, the light trough connecting members 13 are a set including a light trough connecting member 131 of a curved keel structure and a plurality of light trough fastening members 132.

In the embodiment of the socket connector assembly 11 shown in fig. 5 and 6, the socket connector 131 may have an L-shaped structure or a groove-shaped structure (including a third connecting plate connected to the second connecting plate or the first connecting plate), but is not limited thereto.
