Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated suspended ceilings, and particularly relates to a stepped structure of a prefabricated suspended ceiling and an installation method thereof. Background Art

[0002] Prefabricated decoration is a decoration method in which components produced in a factory are assembled and installed on site, mainly including dry construction methods for floors, integrated kitchens, integrated bathrooms, separation of pipelines and structures, etc. Compared with traditional decoration, prefabricated decoration has low on-site pollution, low requirements for finished product protection, factory batch processing, good installation quality, while traditional decoration is time-consuming and laborious and has a high cost.

[0003] For prefabricated decoration, a common prefabricated suspended ceiling is installed in the form of aluminum gusset plates, which is only suitable for the installation of suspended ceilings in small spaces and can only be installed as a flat ceiling structure. After installation, due to the conventional spraying process, the appearance effect is not good.

[0004] In common prefabricated suspended ceilings, support card suspended ceilings, 38-card suspended ceilings, suspended ceilings or snap-together ceiling structures are usually adopted. Among them, for the installation of snap-together gusset plates, it can only be adapted to the installation of flat ceiling structures and cannot display more complex ceiling shapes.

[0005] Among them, a stepped suspended ceiling refers to a suspended ceiling with a lowered elevation that is not on the same plane, in a form similar to a staircase. Artistic suspended ceilings will include the form of steps, but they are much more complex.

[0006] The existing stepped suspended ceilings have the following technical problems:

[0007] 1. For the installation at the stepped position, the traditional installation usually adopts the installation method of multiple small plates, and the operation process is complex;

[0008] 2. In the traditional installation of the stepped position, multiple high-altitude operations are required, and the construction efficiency is low;

[0009] 3. For the installation at the stepped vertical frame position, there is a risk of cracking at the corners in traditional decoration. In traditional decoration, the general method is to cover it by applying putty. For the position of the floor plate, a notch is generally cut in the gypsum board for installation, and corner reinforcement operations are carried out;

[0010] 4. At the joint seams surrounded by the stepped vertical frames, the control effect of the seams at the splicing joints in prefabricated decoration is poor, and the situation of uneven seams will occur;

Detailed implementation mode

[0047] The following will make a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0048] As Figures 1-12 shown, an assembled ceiling stepped structure includes a high-level flat top 1, an enclosing vertical frame 3, and a low-level ceiling 2 arranged in sequence from top to bottom. The high-level flat top 1 is connected to the top of the enclosing vertical frame 3, the low-level ceiling 2 is connected to the bottom of the enclosing vertical frame 3, and a stepped structure is formed between the enclosing vertical frame 3 and the low-level ceiling 2; the enclosing vertical frame 3 is formed by enclosing relatively arranged long sides 3-1 and relatively arranged short sides 3-2, and external corner connecting parts 3-3 are provided at both ends of the long sides 3-1, and clamping parts 3-4 corresponding to the external corner connecting parts 3-3 are provided at both ends of the short sides 3-2; the high-level flat top 1 includes a connected keel 1-1, hanging strip 1-2, and support plate 1-3. The support plate 1-3 is connected to the top of the enclosing vertical frame 3, and leveling parts 6 are provided on both the outside of the enclosing vertical frame 3 and the keel 1-1; a connecting part 2-2 connected to the inside of the enclosing vertical frame 3 is provided on the low-level ceiling 2, and a fixed strip 2-3 is installed on the low-level ceiling 2.

[0049] Both the long sides 3-1 and the short sides 3-2 are hollow structures, and corresponding ribs are provided inside the long sides 3-1 and the short sides 3-2. The cavity has a good heat insulation effect, which can save a certain amount of energy. At the same time, the cavity design can save materials to achieve the purpose of light weight. In addition to improving the overall strength of the plate, the middle ribs can also provide better nail holding force and nail driving support for the plate.

[0050] The overall enclosing vertical frame 3 adopts a 600 modulus design and can be cut according to the required height on site. The conventional width can be cut into two. The two ends of the enclosing vertical frame 3 are designed with bevels, which can be fixed more tightly when nailing, and the seam control effect on the appearance will be better. The extrusion process is mainly based on the cross-section design and actual material selection. Other production forms can still meet the use effect when making this cross-section shape.

[0051] The size of the high-position flat top 1 is consistent with the horizontal cross-sectional size of the enclosing vertical frame 3. The high-position flat top 1 forms a blockage of the middle frame structure of the enclosing vertical frame 3. At the same time, the high-position flat top 1 is horizontally arranged at the top of the enclosing vertical frame 3, and the low-position ceiling 2 is horizontally connected to the bottom of the enclosing vertical frame 3. Moreover, the size of the low-position ceiling 2 is larger than that of the enclosing vertical frame 3, so that a stepped structure is formed between the low-position ceiling 2 and the enclosing vertical frame 3.

[0052] The bottom of the enclosing vertical frame 3 is a vertical structure, and the low-position ceiling 2 is a horizontal structure. The low-position ceiling 2 is connected to the inner and outer sides of the enclosing vertical frame 3. A stepped structure is formed between the outer side of the enclosing vertical frame 3 and the low-position ceiling 2, and the inner side of the enclosing vertical frame 3 is connected to the low-position ceiling 2.

[0053] A keel hanger 1-4 is hung at the bottom of the keel 1-1. Insertion holes corresponding to the hanging strips 1-2 are formed on the keel hanger 1-4. And the hanging strips 1-2 pass through the corresponding keel hangers 1-4 on all the keels 1-1 at the same time. The hanging strips 1-2 are vertically arranged with respect to the keels 1-1, and the hanging strips 1-2 are located below the keels 1-1. Under the action of the keel hanger 1-4, the connection between the hanging strips 1-2 and the keels 1-1 is realized, and the hanging strips 1-2 and the keels 1-1 are connected in a vertical and horizontal manner.

[0054] Clamping edges are formed on both sides of the keel 1-1. Flanging edges adapted to the clamping edges are formed at the top of the keel hanger 1-4. The keel hanger 1-4 is hung on the keel 1-1, and the keel hanger 1-4 can slide along the length direction of the keel 1-1. Thus, the keel hanger 1-4 can be moved on the keel 1-1 according to actual needs, which is convenient for the connection between the keel 1-1 and the hanging strips 1-2.

[0055] A frame bone connector 4 connected to the keel hanger 1-4 is provided on the outer side of the enclosing vertical frame 3. The frame bone connector 4 is connected to the outer wall of the long side 2-1. The frame bone connector 4 includes a horizontal plate, a vertical plate and an inclined plate connected in sequence from top to bottom. The horizontal plate, the vertical plate and the inclined plate are connected in sequence to form a C-shaped structure.

[0056] The keel hanger 1-4 is of a U-shaped structure. The horizontal plate is placed on the bottom of the keel hanger 1-4. The vertical plate is in contact with the outer side of the support plate 1-3. The inclined plate abuts against the bottom of the support plate 1-3. The inclined plate slopes upward. Thus, under the action of the inclined plate, the end of the inclined plate is clamped at the stepped structure formed by the outer side of the support plate 1-3 and the outer side of the long side 2-1. At the same time, the vertical plate is in contact with the outer side of the support plate 1-3, and the vertical plate has better stability.

[0057] Under the action of the frame bone connector 4, the keel hanger 1-4 can be tightened, thereby increasing the connection between the frame bone connector 4 and the keel hanger 1-4 and making the connection more stable.

[0058] On the outside of the enclosing vertical frame 3, there is a vertical frame hanging member 5 corresponding to the leveling member 6. The leveling member 6 includes a screw rod and a locking nut connected to each other. Both the keel 1-1 and the vertical frame hanging member 5 are formed with slot holes adapted to the leveling member 6.

[0059] There are at least two locking nuts formed on the screw rod. By rotating the screw rod, the two locking nuts are respectively located on the inner and outer sides of the slot hole of the keel 1-1. Similarly, the two locking nuts are respectively located on the upper and lower sides of the vertical frame hanging member 5.

[0060] After the lower locking nut is positioned under the action of hand or tool, by rotating the screw rod, the telescopic length of the screw rod is adjusted. When adjusted to a certain length, the upper locking nut locks the position of the screw rod, so as to realize the adjustment of the length of the screw rod and the adjustment of the distance between the keel 1-1 and the roof or the distance between the roof and the enclosing vertical frame 3.

[0061] The vertical frame hanging member 5 is of L-shaped structure, and the top of the vertical frame hanging member 5 abuts against the bottom of the support plate 1-3. And the bottom of the vertical frame hanging member 5 is fixedly connected to the short side 2-2 by screws. The top of the vertical frame hanging member 5 is a horizontal structure, and the bottom of the vertical frame hanging member 5 is a vertical structure. There is an inclined structure formed between the vertical structure and the horizontal structure. The inclined structure relative to the outer side of the support plate 1-3 and the stepped structure formed by the outer side of the short side 1-2 can provide better support for the horizontal structure.

[0062] An inner concave structure 3-8 is formed on the external angle connecting member 3-3. An arched structure 3-9 corresponding to the inner concave structure 3-8 is formed on the clamping member 3-4. And an upper end mating opening 3-5 and a lower end mating opening 3-6 are formed at the inner concave structure 3-8. A clamping head 3-7 adapted to the upper end mating opening 3-5 or the lower end mating opening 3-6 is formed at the arched structure 3-9.

[0063] Two clamping members 3-4 are provided at the end of the short side 3-2. The two clamping members 3-4 are respectively located on the upper and lower sides of the short side 3-2.

[0064] The bottoms of the upper end mating opening 3-5 and the lower end mating opening 3-6 are both horizontal structures. And the top of the upper end mating opening 3-5 is communicated with the top of the external angle connecting member 3-3. An opening-downward clamping groove is formed between the two ends of the corresponding clamping member 3-4 and the clamping head 3-7. The bottom of the clamping groove is a horizontal structure.

[0065] After the clamping member 3-4 is clamped to the corresponding upper mating opening 3-5 or lower mating opening 3-6, under the action of the bottom of the clamping groove of the horizontal structure and the bottoms of the upper mating opening 3-5 and lower mating opening 3-6 of the horizontal structure, the bottom of the clamping groove is horizontally attached to the bottoms of the upper mating opening 3-5 and lower mating opening 3-6, ensuring a better contact area between the clamping member 3-4 and the corner splicing member 3-3 while ensuring that the clamping member 3-4 is horizontally arranged on the corner splicing member 3-3.

[0066] The low ceiling 2 includes a low board 2-1 of a frame structure. The connecting member 2-2 and the fixing strip 2-3 are both fixedly connected to the low board 2-1, and the connecting member 2-2 and the fixing strip 2-3 are located on the inner and outer sides of the enclosing vertical frame 3.

[0067] The connecting member 2-2 is of an L-shaped structure. The bottom of the connecting member 2-2 is fixedly connected to the low board 2-1, and the top of the connecting member 2-2 is fixedly connected to the inner side of the enclosing vertical frame 3. The connecting member 2-2 and the low board 2-1 are fixedly connected by screws. Similarly, the connecting member 2-2 and the enclosing vertical frame 3 are also fixedly connected by screws.

[0068] During the actual use process, it includes the following steps:

[0069] Step A: Design the sizes of the high ceiling 1, the enclosing vertical frame 3, and the low ceiling 2 according to actual needs, and design the long side 3-1, short side 3-2, keel 1-1, hanging strip 1-2, low board 2-1, and fixing strip 2-3 with certain sizes. The length of the long side 3-1 is greater than the length of the short side 3-2. The horizontal cross-sectional sizes of the high ceiling 1 and the enclosing vertical frame 3 are the same. The low ceiling 2 is also of a frame structure, and the size of the low ceiling 2 is greater than the size of the enclosing vertical frame 3.

[0070] Step B: The splicing and installation of the enclosing vertical frame 3. Clamp the corner connecting member 3-3 on the long side 3-1 with the clamping member 3-4 on the short side 3-2, and splice each long side 3-1 and short side 3-2 in sequence to form the enclosing vertical frame 3 of a frame structure. The enclosing vertical frame 3 includes two long sides 3-1 and two short sides 3-2, and the two long sides 3-1 are arranged oppositely. Similarly, the two short sides 3-2 are also arranged oppositely. The height of the long side 3-1 is the same as the height of the short side 3-2. Connect the long side 3-1 and the short side 3-2 at the same horizontal height. Both ends of the long side 3-1 are connected to the two oppositely arranged short sides 3-2 at the same time. Similarly, both ends of the short side 3-2 are connected to the two oppositely arranged long sides 3-1 at the same time.

[0071] Step C: Insert the keel hanging member 1-4 onto the hanging strip 1-2, insert several hanging strips 1-2 onto the corresponding support plate 1-3, move the keel hanging member 1-4 to the corresponding position on the hanging strip 1-2, and place the keel 1-1 on the corresponding keel hanging member 1-4 to connect the keel hanging member 1-4 with the keel 1-1, thus realizing the connection among the support plate 1-3, the hanging strip 1-2 and the keel 1-1.

[0072] Slot holes corresponding to the hanging strip 1-2 are formed on the keel hanging member 1-4. After inserting the keel hanging member 1-4 onto the hanging strip 1-2, insert the hanging strip 1-2 onto the corresponding support plate 1-3 to realize the fixed connection among the keel hanging member 1-4, the support plate 1-3 and the hanging strip 1-2.

[0073] Then insert the corresponding keel 1-1 into the corresponding keel hanging member 1-4 to realize the overall connection.

[0074] Step D: After assembling the keel 1-1 and the hanging strip 1-2, install the leveling member 6 on the keel 1-1, install the keel 1-1 on the roof, connect the leveling member 6 with the roof, lift the entire enclosing vertical frame 3, and fixedly connect the support plate 1-3 with the top of the enclosing vertical frame 3 to realize the connection between the enclosing vertical frame 3 and the high-level flat top 1.
