Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated buildings, and particularly relates to a lightweight prefabricated gypsum ceiling. Background Technique

[0002] The prefabricated structure is a concrete structure mainly composed of prefabricated components assembled or connected. The prefabricated building refers to transferring a large amount of on-site operation work in the traditional construction method to the factory. The building components and fittings are processed and manufactured in the factory, and then transported to the building construction site and assembled and installed on-site through reliable connection methods. At the same time, the prefabricated decorative ceiling, that is, the gypsum board ceiling, first installs the keel steel frame on the roof structure, and then lays and seals the gypsum board.

[0003] The patent with the authorization announcement number CN217500744U discloses a gypsum board prefabricated ceiling. In this technical solution, the gypsum board is preliminarily fixed by a buckle group. Due to the limited connection strength of the buckle group, screws are ultimately needed for installation and fixation, which affects the work efficiency. And due to the existence of the buckle group, after the gypsum board is installed, a complete plane is formed between the gypsum boards, and there is only a very small gap between the gypsum boards. When it is necessary to replace the gypsum board, it is difficult to find an effective force application point to separate the gypsum board from the buckle group. Therefore, the disassembly is very difficult, and even the original structure of the gypsum board needs to be damaged to complete the removal.

[0004] Therefore, we propose a lightweight prefabricated gypsum ceiling to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art that the connection strength of the buckle group is limited, screws are needed for installation and fixation, which affects the work efficiency and is not convenient for disassembly, and a lightweight prefabricated gypsum ceiling is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A lightweight prefabricated gypsum ceiling, including an installation keel and a gypsum board. A suspension rod is fixedly arranged on the installation keel, and the suspension rod is fixed to the roof. A quick installation and disassembly mechanism is arranged between the installation keel and the gypsum board;

[0008] The quick installation and disassembly mechanism includes an installation ring fixedly arranged on the bottom surface of the installation keel. A positioning column is installed on the gypsum board, and a connection cap is fixedly arranged on the top of the positioning column. The diameter of the connection cap is smaller than the inner diameter of the installation ring. A clamping structure for limiting the connection cap is arranged in the installation ring;

[0009] A disc-shaped piece for controlling the connection cap to disengage from the installation ring is slidably arranged on the positioning column.

[0010] Furthermore, at least four positioning posts are installed on a single gypsum board, and the four positioning posts are equidistantly distributed. The installation rings on the installation keel are distributed in one-to-one correspondence with the positioning posts.

[0011] Furthermore, one end of the connecting cap close to the installation ring is a conical surface.

[0012] Furthermore, the clamping structure includes a plurality of sliders slidably arranged radially on the installation ring. An installation frame corresponding to the sliders is fixedly arranged on the outer side of the installation ring, and a first spring is arranged between the installation frame and the sliders.

[0013] Furthermore, the slider has an inclined side and a flat side, and the inclined side corresponds to the conical surface of the connecting cap.

[0014] Furthermore, a guiding groove is formed on the side of the slider, and a guiding strip is arranged inside the installation ring. The guiding strip is slidably connected with the guiding groove.

[0015] Furthermore, the disc-shaped piece has an upper inclined surface and a lower inclined surface. A hidden groove is formed on one side of the connecting cap close to the disc-shaped piece, and the hidden groove is consistent with the contour of the upper inclined surface of the disc-shaped piece.

[0016] Furthermore, a second spring coaxially arranged with the installation ring is also arranged on the installation keel, and a butting ring capable of butting and cooperating with the connecting cap is arranged at the bottom end of the second spring.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0026] As Figures 1-3 , a lightweight prefabricated gypsum ceiling includes an installation keel 1 and a gypsum board 2. Two installation keels 1 are installed side by side to form a group. A suspension rod 11 is fixedly arranged on the installation keel 1, and the suspension rod 11 is fixed to the roof. A quick installation and disassembly mechanism 3 is arranged between the installation keel 1 and the gypsum board 2. Through the quick installation and disassembly mechanism 3, the gypsum board 2 can be quickly fixed on the installation keel 1 without using screws, and can be easily removed, improving the construction efficiency.

[0027] The quick installation and disassembly mechanism 3 includes an installation ring 31 fixedly arranged on the bottom surface of the installation keel 1. A positioning post 21 is installed on the gypsum board 2. A connecting cap 22 is fixedly arranged at the top of the positioning post 21. The diameter of the connecting cap 22 is smaller than the inner diameter of the installation ring 31. The positioning post 21 can be coaxially corresponding to the installation ring 31 to pass the connecting cap 22 through the installation ring 31. One end of the connecting cap 22 close to the installation ring 31 is a conical surface. A clamping structure for limiting the connecting cap 22 is arranged in the installation ring 31. After the connecting cap 22 enters the installation ring 31, the connecting cap 22 can be axially limited through the clamping structure, so that the connecting cap 22 cannot be pulled outwards, realizing the connection between the positioning post 21 and the installation ring 31, and further fixing the positions of the gypsum board 2 and the installation keel 1.

[0028] As Figures 2-4, the snap connection structure includes a plurality of sliders 32 slidably arranged radially on the mounting ring 31. An installation frame 33 corresponding to the sliders 32 is fixedly arranged on the outer side of the mounting ring 31. A first spring 34 is arranged between the installation frame 33 and the sliders 32. Under the elastic force of the first spring 34, the sliders 32 extend towards the center of the mounting ring 31. The sliders 32 have a bevel edge 321 and a flat edge 322. The bevel edge 321 corresponds to the conical surface of the connecting cap 22. By pressing the gypsum board 2 towards the installation keel 1 side, the connecting cap 22 enters the mounting ring 31, so that the conical surface of the connecting cap 22 abuts against the bevel edge 321 of the slider 32, causing the slider 32 to receive a radially outward thrust along the mounting ring 31, making the slider 32 slide outward and compress the first spring 34 until the bevel edge 321 disengages from the conical surface of the connecting cap 22, then the first spring 34 resets, and the slider 32 extends again, so that the flat edge 322 of the slider 32 abuts against the lower edge of the connecting cap 22, and the connecting cap 22 is supported by the flat edge 322 of the slider 32, making the connecting cap 22 unable to be pulled out in the reverse direction.

[0029] Refer to Figures 2-4 , a second spring 12 coaxially arranged with the mounting ring 31 is further provided on the installation keel 1. An abutting ring 13 that can abut and cooperate with the connecting cap 22 is arranged at the bottom end of the second spring 12. When the positioning post 21 is inserted into the mounting ring 31, the connecting cap 22 abuts against the abutting ring 13 and compresses the second spring 12 as the connecting cap 22 moves. Through the elastic force of the second spring 12, the connecting cap 22 is tightly abutted against the flat edge 322 of the slider 32, improving the stability of the installation of the gypsum board 2 and reducing the risk of the gypsum board 2 shaking.

[0030] As Figures 2-4 , a guiding groove is formed on the side of the slider 32, and a guiding strip is arranged inside the mounting ring 31. The guiding strip is slidably connected with the guiding groove. Through the mutual cooperation of the guiding strip and the guiding groove, the slider 32 is limited, ensuring the accuracy and stability of the position movement of the slider 32.

[0031] As Figures 1-4 , at least four positioning posts 21 are installed on a single gypsum board 2, and the four positioning posts 21 are equidistantly distributed, ensuring that the forces at each position are balanced after the gypsum board 2 is fixed during installation, improving the installation stability. The mounting rings 31 on the installation keel 1 are distributed in one-to-one correspondence with the positioning posts 21, ensuring that the positioning posts 21 and the mounting rings 31 can be aligned. When the gypsum board 2 is installed, it needs to cooperate with a group of installation keels 1, and the positioning posts 21 on the gypsum board 2 cooperate with the mounting rings 31 on different installation keels 1 respectively, ensuring the installation stability.

[0032] To facilitate the disassembly of the gypsum board 2, a disc-shaped piece 23 for controlling the disengagement of the connecting cap 22 from the mounting ring 31 is slidably arranged on the positioning post 21. The disc-shaped piece 23 is located below the connecting cap 22. The disc-shaped piece 23 has an upper inclined surface and a lower inclined surface. A hidden groove 221 is formed on one side of the connecting cap 22 close to the disc-shaped piece 23. The hidden groove 221 has the same contour as the upper inclined surface of the disc-shaped piece 23. When the disc-shaped piece 23 slides upward into the hidden groove 221, the upper inclined surface of the disc-shaped piece 23 is completely shielded in the hidden groove 221, so that the joint of the upper inclined surface and the lower inclined surface of the disc-shaped piece 23 coincides with the bottom surface of the connecting cap 22.

[0033] By pressing the gypsum board 2 upward, the positioning post 21 continues to move upward, compressing the second spring 12. In the state where the gypsum board 2 is installed and fixed, the slider 32 is located between the connecting cap 22 and the disc-shaped piece 23. As the gypsum board 2 moves upward, the upper inclined surface of the disc-shaped piece 23 abuts against the inclined edge 321 of the slider 32, causing the slider 32 to receive a radially outward thrust along the mounting ring 31, so that the slider 32 slides outward and compresses the first spring 34. Until the inclined edge 321 disengages from the upper inclined surface of the disc-shaped piece 23, the first spring 34 resets, and the slider 32 extends out again, making the flat edge 322 of the slider 32 abut against the lower inclined surface of the disc-shaped piece 23. At this time, the gypsum board 2 is pulled out downward. Under the elastic force of the second spring 12, the gypsum board 2 moves downward without manual force. While the flat edge 322 of the slider 32 remains in contact with the lower inclined surface of the disc-shaped piece 23, it drives the disc-shaped piece 23 to move upward until the disc-shaped piece 23 coincides with the hidden groove 221 in the connecting cap 22. At this time, the disc-shaped piece 23 is blocked by the connecting cap 22 and cannot move anymore. The pressing force between the flat edge 322 of the slider 32 and the lower inclined surface of the disc-shaped piece 23 increases, causing the slider 32 to receive a radially outward thrust along the mounting ring 31, so that the slider 32 slides outward and compresses the first spring 34. Until the slider 32 disengages from the lower inclined surface of the disc-shaped piece 23, the first spring 34 resets, and the slider 32 extends out directly to the outside of the conical surface of the connecting cap 22 to achieve disengagement.

[0034] The working principle of the present utility model is as follows:

[0035] During installation, two installation keels 1 are installed side by side to form a group and fixed to the roof by the hanging rods 11. The installation spacing of each group of installation keels 1 is controlled so that the sides of the gypsum board 2 are in contact when installed. By pressing the gypsum board 2 against one side of the installation keel 1, the connecting cap 22 enters the mounting ring 31, so that the conical surface of the connecting cap 22 abuts against the inclined edge 321 of the slider 32, causing the slider 32 to receive a radially outward thrust along the mounting ring 31, so that the slider 32 slides outward and compresses the first spring 34. Until the inclined edge 321 disengages from the conical surface of the connecting cap 22, the first spring 34 resets, and the slider 32 extends out again, making the flat edge 322 of the slider 32 abut against the lower edge of the connecting cap 22. The connecting cap 22 is supported by the flat edge 322 of the slider 32, so that the connecting cap 22 cannot be pulled out in the reverse direction to complete the installation.

[0036] When disassembling, continue to press the gypsum board 2 upward. The upper inclined surface of the disc-shaped piece 23 abuts against the inclined edge 321 of the slider 32, so that the slider 32 is subjected to a radially outward thrust along the mounting ring 31, causing the slider 32 to slide outward until the inclined edge 321 disengages from the upper inclined surface of the disc-shaped piece 23. Then the slider 32 resets, and the flat edge 322 of the slider 32 abuts against the lower inclined surface of the disc-shaped piece 23. At this time, drag the gypsum board 2 downward. The gypsum board 2 moves downward under the elastic force of the second spring 12. When the flat edge 322 of the slider 32 remains in contact with the lower inclined surface of the disc-shaped piece 23, it drives the disc-shaped piece 23 to move upward until the disc-shaped piece 23 coincides with the hidden groove 221 in the connecting cap 22. At this time, the disc-shaped piece 23 is blocked by the connecting cap 22 and cannot move any further. The pressing force between the flat edge 322 of the slider 32 and the lower inclined surface of the disc-shaped piece 23 increases, causing the slider 32 to be subjected to a radially outward thrust along the mounting ring 31 until the slider 32 disengages from the lower inclined surface of the disc-shaped piece 23. Then the slider 32 extends again and directly reaches the outside of the conical surface of the connecting cap 22 to achieve disengagement.
