Description

Technical Field

[0001] The invention relates to the technical field of assembled ceilings, and in particular to an assembled stepped ceiling. Background Art

[0002] In the process of interior decoration, in order to increase the various functions of the ceiling or improve the aesthetics of the ceiling, the ceiling is often set in the form of a step-down structure. At present, the traditional ceiling step-down device is generally made of multiple gypsum boards spliced ​​together. The traditional gypsum board ceiling step-down device is generally made of a wooden keel or a light steel keel as a keel frame. First, the wooden keel or the light steel keel is fixed on the indoor ceiling, and then the spliced ​​gypsum board is nailed to the keel with a gun nail, and then an anti-rust layer is applied. The gap part is flattened with putty, and then painted with latex paint after drying. It can be seen that the construction process of the traditional ceiling step-down device is relatively complicated, and it is necessary to process the panels and apply the paint on site. It is not only easy to affect human health due to the pollution of the construction site environment, but also this traditional construction cycle is relatively long, increasing labor costs, and cannot achieve rapid construction. Therefore, it is very necessary to design a ceiling step-down device with simple process, short construction period and low pollution, so as to overcome the above-mentioned defects of the traditional ceiling step-down device.

DETAILED DESCRIPTION

[0025] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] An assembled drop ceiling, such as Figure 1 As shown, it includes a high-position ceiling 1, a low-position ceiling 2 and a step-down plate 3 for connecting the high-position ceiling 1 and the low-position ceiling 2.

[0027] During installation, the high-position ceiling 1 is first connected to the top wall. In this embodiment, the stability of the high-position ceiling 1 is jointly ensured by keel hanging and square tube connection. Keel hanging means: first, a number of parallel keels are installed on the back of the high-position ceiling 1, and then the keels are connected to the top wall through expansion bolts. In this embodiment, a "J"-shaped keel is selected, which includes a top plate, side plates arranged at both ends of the top plate, and flange plates respectively arranged on the side plates. The flange plates are used to connect with the high-position ceiling 1, and the top plate is used to connect with the top wall through expansion bolts. When the flange plate is connected to the high-position ceiling 1, it can be directly connected with screws, or a pressing piece can be first set on the back of the high-position ceiling 1. This pressing piece includes an extension plate connected non-parallel to the high-position ceiling 1, and a pressing plate connected non-parallel to the extension plate. A pressing groove is formed between the pressing plate, the extension plate and the high-position ceiling 1, and the flange plate of the keel can be inserted into the pressing groove. If the extension plate is directly connected to the high ceiling 1, there will be problems such as small connection area and easy falling off. Therefore, the pressed part also includes a fixed plate parallel to and connected to the high ceiling 1. The extension plate is arranged on the fixed plate. The fixed plate, the extension plate and the pressed plate are formed in one piece. Furthermore, threaded holes can be arranged on the pressed plate. At the same time, the pressed part also includes fastening nails threadedly connected to the threaded holes. After the flange plate is inserted into the pressing groove, the fastening nail is rotated so that the fastening nail moves downward under the action of the thread until the end of the fastening nail is pressed against the flange plate. Square tube connection refers to: if Figure 2 As shown, the high ceiling 1 is used to set the two ends of the step-down plate 3, which are overlapped on the square tube 11 respectively. The two ends of the square tube 11 are respectively connected to the second side wall perpendicular to the side wall through fixed lines. The fixed line includes a second connecting plate 12 parallel to and connected to the second side wall, and a receiving plate 13 perpendicular to the second connecting plate 12 for the square tube 11 to overlap. An L-shaped limiting line is also provided on the fixed line, and the limiting line includes a connecting plate connected to the receiving plate 13 and a limiting plate connected to the square tube 11. A reinforcing hook body is also provided, which is connected to the top wall through an expansion screw, and the middle part of the square tube 11 is overlapped on the reinforcing hook body.

[0028] After the installation of the high ceiling 1 is completed, the step-down board 3 can be installed. Figure 3 As shown, in this embodiment, the step-down plate 3 is a flat plate perpendicular to the high ceiling 1. Directly connecting the end of the step-down plate 3 to the high ceiling 1 has the problem of small connection area and easy falling off. Therefore, a contact plate 31 parallel to and connected to the high ceiling 1 is provided at the end of the step-down plate 3. The step-down plate 3 and the contact plate 31 are integrally formed. Figure 3 As shown, the abutting plate 31 is designed to be thicker, so that the abutting plate 31 can also abut against the receiving plate 13, that is, the abutting plate 31 is clamped between the high ceiling 1 and the receiving plate 13, thereby improving the installation stability of the step-down plate 3.

[0029] The abutment plate 31 can also be connected to the high ceiling 1 through a connecting member. This connecting member can include a first lap plate inserted between the high ceiling 1 and the square tube 11, and a first connecting plate connected to the abutment plate 31. A reinforcing connecting plate for connecting to the step-down plate 3 can also be provided at the end of the first connecting plate. This plug-in connection method has the characteristics of convenient and stable installation and easy disassembly. At the same time, the first lap plate is tightly pressed against the square tube 11 by the ceiling 1 with a certain mass, thereby ensuring the connection stability of the step-down plate 3. In order to further improve the structural strength and connection strength of the connecting member, the first connecting plate and the first lap plate are connected by a U-shaped plate. The U-shaped plate includes a bottom and side portions respectively arranged at both ends of the bottom, and a limiting groove for the insertion of the square tube 11 is formed between the bottom and the side portions. At this time, one side is connected to the first lap plate, and the other side is connected to the first connecting plate.

[0030] After the installation of the step-down plate 3 is completed, the low-position ceiling 2 can be installed. The low-position ceiling 2 requires at least two connection points, one connection point is at the side wall connection end of the low-position ceiling 2, connected to the side wall; the other connection point is connected to the step-down plate 3, which can be set on the free end of the low-position ceiling 2 opposite to the side wall connection end, or set on the part of the low-position ceiling 2 located between its center and the free end. In this embodiment, this connection point is set on the back of the low-position ceiling 2, and the connection point divides the low-position ceiling 2 into a non-installation part close to the side wall and an installation part away from the side wall. The installation part can be installed with additional structures such as lighting lamps. In order to prevent the additional structure from falling from the installation part, a stopper is also set at the end of the installation part. The stopper includes a stopper plate parallel to the step-down plate 3, and two clamps are vertically arranged on the stopper plate. A groove for inserting the end of the installation part is formed between the two clamps. In order to facilitate the removal of the stopper, the clamping plate located below is L-shaped, including a connecting portion perpendicular to the stopper plate and a clamping portion perpendicular to the connecting portion, and the end of the clamping portion abuts against the mounting portion.

[0031] In order to improve the installation and removal efficiency of the low-position ceiling 2, the present application uses an overlapping method, such as Figure 3 As shown, the low-position ceiling 2 is connected to the side wall and the step-down plate 3 respectively through a hanging structure, and the hanging structure includes a fixed plate 41 arranged on the side wall or the step-down plate 3, and a hanging member arranged on the low-position ceiling 2, and the hanging member includes a lap plate 42 overlapped on the fixed plate 41. The installation of the low-position ceiling 2 can be completed by overlapping the lap plate 42 on the fixed plate 41. In order to ensure the stability of the overlap, the fixed plate 41 is preferably arranged parallel to the low-position ceiling 2.

[0032] In order to install the lap plate 42, as Figure 4As shown, the hanging parts also include a mounting plate 43 which is parallel to and connected to the back of the low ceiling 2. The lap plate 42 and the mounting plate 43 are connected via the side plate 44, so that a space for the fixing plate 41 to be inserted is formed between the lap plate 42 and the low ceiling 2, which is convenient for installation. During installation, it is preferred to insert the fixing plate 41 to the bottom so that the side plate 44 abuts against the side of the fixing plate 41. At the same time, the height of the space can be made consistent with the thickness of the fixing plate 41, so that the fixing plate 41 abuts against the back of the low ceiling 2, and the connection strength can be further improved through the effect of abutment friction. In addition, as Figure 5 As shown, in order to further improve the installation stability, the hanging member further includes a reinforcing plate 45 parallel to and connected to the side wall or the step-down plate 3 , and the reinforcing plate 45 is connected to the lap plate 42 .

[0033] The fixing plate 41 is the main bearing member of the overlap structure, and its stability is also very important. When the low-position ceiling 2 overlaps the side wall, the fixing plate 41 is first installed on the side wall. In order to ensure the stability of the fixing plate 41, the side wall and the fixing plate 41 are connected by a first connecting plate 46. The first connecting plate 46 is parallel to and connected to the side wall, and the first connecting plate 46 and the fixing plate 41 are integrally formed. Then, a hanging piece is set on the low-position ceiling 2 so that its overlapping plate 42 is overlapped on the fixing plate 41. Figure 1 As shown, in order to reduce consumables, the hanging pieces can be set to be narrower, and then a fixing plate 41 is connected to at least two hanging pieces to ensure the overlapping strength.

[0034] When the low-position ceiling 2 is overlapped with the step-down board 3, the fixing board 41 is first installed at the end of the step-down board 3. In order to ensure the stability of the fixing board 41, the step-down board 3 and the fixing board 41 can be directly formed into one piece. Then, a hanging piece is arranged on the low-position ceiling 2 so that the overlapping board 42 is overlapped with the fixing board 41.

[0035] In addition, the fixing plates 41 of the side wall and the step-down plate 3 are in contact with the non-installation portion, so that the free ends of the two fixing plates 41 are opposite to each other, so that the low-position ceiling 2 is not easy to fall off when it moves left and right due to external force.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
