Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a prefabricated building board with a connection structure. Background Art

[0002] Prefabricated buildings are structures that shift much of the on-site work involved in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, and balconies) are manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connections. Prefabricated buildings primarily include prefabricated concrete structures, steel structures, and modern wood structures. They exemplify modern industrialized production methods due to their standardized design, factory-based production, prefabricated construction, information-based management, and intelligent applications. Panel construction is a common type of prefabricated building, reducing structural weight, improving labor productivity, and expanding the building's usable area and earthquake resistance.

[0003] After searching, the Chinese invention patent, publication number: CN112343251A, named: A prefabricated panel with an external connection structure. The invention connects multiple panels to form a wall through external rods, and quickly positions them through locking parts, so that the originally built-in connectors can be directly visible to the outside, especially the connection parts, and the connection status can be directly obtained from the outside, which can meet the acceptance and subsequent maintenance requirements.

[0004] However, in actual use, the above and similar technical solutions still have some problems:

[0005] 1. The current partitions are fixed by clamping with external fixing columns. This design is visually abrupt and poorly coordinated with the overall architectural style, seriously affecting the aesthetic appearance of the building. In addition, the partition layer structure is simple and does not use effective sound insulation materials or structures. It cannot effectively block the transmission of sound, and the sound insulation performance is poor, which is difficult to meet actual usage needs.

[0006] 2. The partitions and columns are installed in a direct contact manner, which requires extremely high dimensional accuracy of the partitions. During installation, in order to ensure the fit, the partitions need to be cut. This not only increases the construction difficulty and time cost, but also easily causes irreversible damage to the internal structure of the partitions due to improper operation during the cutting process, affecting their performance and service life;

[0007] 3. There are connecting gaps between the partitions and the columns. In a humid environment, water vapor in the air can easily penetrate into the interior of the partition through these gaps. Due to the limited hygroscopicity and waterproof performance of the partition material, mold is easily grown inside after being exposed to moisture for a long time, causing the partition to become moldy. This not only affects the appearance, but also reduces the strength of the partition and shortens its service life. Summary of the Invention

[0022] Compared with the prior art, the present invention provides a prefabricated building board with a connection structure, which has the following beneficial effects:

[0023] 1. The assembled building panel with a connection structure installs a pair of columns between two walls that need to be partitioned, and fastens the partition to the fixed column through the clamping claw. The first screw is rotated to drive the clamping claw to close, thereby clamping and limiting the fixed column to prevent the partition from falling off and facilitating disassembly. After multiple partitions are installed, the first worm is rotated to drive the fixed column and the partition to move, so that the partition is inserted into the interior of the column, thereby perfectly closing the partition and the column. Foam glue can be filled between each pair of partitions to increase sound insulation and firmness.

[0024] 2. The prefabricated building board with a connection structure allows gas to enter the air pipe through an air pump, causing the first air bag and the second air bag to expand. When the second air bag expands, it will resist and wrap the outer wall of the partition, thereby reducing the entry of water vapor into the interior of the column and preventing the inner side of the partition from mold. The second screw rod is driven to rotate and the slider moves downward. When the first air bag is expanded, the spring will be compressed. During use, the air inside the first air bag and the second air bag will be lost and leaked. The compression potential energy of the spring will push the pressure block downward, thereby squeezing the first air bag. When the air pipe is connected, the second air bag remains in an expanded state, thereby ensuring the effect of isolating water vapor and ensuring the continuous operation of the second air bag.

[0025] 3. During the disassembly process, the prefabricated building panel with a connection structure rotates the drive rod, thereby driving the first bevel gear and the second bevel gear to rotate, driving the winding disk to reel in the cutting wire, and the cutting wire detaches from the installation groove, bypasses the base, and cuts the foam glue. The cutting wire uses an electric heating wire, which generates heat after being powered on, increasing the cutting ability of the foam glue, thereby facilitating the disassembly and separation of the partition, avoiding damage to the partition, and increasing utilization.

The column 1 is located on the outside of the handle 331 and is buckled with a shielded cover 31, so as to facilitate driving the rotating rod 333 to rotate.

[0043] Example 2: Based on Example 1, a prefabricated building panel with a connection structure is provided, wherein a peeling mechanism 4 is connected to the partition 21, and the peeling mechanism 4 includes a mounting block 41. The mounting block 41 is mounted on the side wall of the partition 21, and a mounting groove 45 is provided on the side of the partition 21 close to the fixed column 32. The partition 21 is bonded with a cutting wire 42 through the mounting groove 45, and both ends of the cutting wire 42 are connected to the mounting block 41, so as to facilitate the cutting of the foam glue and facilitate the disassembly of the partition 21.

[0044] In the present invention, the mounting block 41 is connected to a driving assembly 43, and the driving assembly 43 includes a driving rod 431. The outer wall of the mounting block 41 is embedded with a driving rod 431 that is rotatably connected. The protruding end of the driving rod 431 is provided with a hexagonal groove.

Specifically, the cutting wire 42 is made of Cr20Ni80 material, so that it is heated during the cutting process to improve the cutting effect.

[0046] Example 3: Based on Example 2, an assembled building panel with a connection structure is provided, wherein a closing mechanism 5 is connected to the column 1, the closing mechanism 5 includes a second air bag 59, and a partition 21 close to one end of the column 1 is plugged into the column 1. An annular second air bag 59 is provided at the connection between the column 1 and the partition 21, and the inner side of the second air bag 59 is in close contact with the partition 21, thereby increasing the airtightness and preventing water vapor from entering.

[0047] In the present invention, an embedded air pipe 51 is installed on the column 1, and a gate valve is installed on the embedded end of the air pipe 51. One end of the air pipe 51 is installed on the second air bag 59, and the second air bag 59 is connected to the air pipe 51. A first air bag 58 is installed on the column 1, and one end of the air pipe 51 is installed on the first air bag 58, and the air pipe 51 is connected to the first air bag 58. A pressure block 57 is installed above the first air bag 58, and a slider 54 is connected to the column 1. A spring 56 is installed between the slider 54 and the pressure block 57 to keep the second air bag 59 inflated. The use of air bag sealing facilitates later disassembly, especially in prefabricated buildings and cabins, which is easy to recycle and can be quickly transferred to secondary construction after simple cleaning.

[0048] In the present invention, a second screw rod 55 is rotatably connected to the column 1, and the second screw rod 55 is threadedly connected to the slider 54. A second worm gear 53 is installed on the second screw rod 55. The outer wall of the column 1 is rotatably connected to an embedded second worm rod 52, and the second worm rod 52 is engaged with the second worm gear 53. The protruding end of the second worm rod 52 is provided with a hexagonal groove, so as to facilitate the control of the compression and extension of the spring 56 and facilitate the replenishment of air in the second airbag 59.

[0049] Working principle: A pair of columns 1 are installed between the two walls that need to be partitioned. A strip groove is provided on one side of the column 1, which is convenient for fixing and installing with glue or cement. The partition 21 is buckled onto the fixing column 32 through the clamping claw 26. When the inner side of the clamping claw 26 contacts the fixing column 32, the handle 331 is inserted into the hexagonal groove of the first screw rod 22, and the handle 331 is turned to drive the first screw rod 22 to rotate, thereby driving the push block 23 to slide. The push block 23 has a polygonal structure. The push block 23 passes through the fixed block 24. The push block 23 is located on both sides of the fixed block 24 and is inclined. The push block 23 extends into the inside of the fixed block 24. The push block 23 pushes the fixed block 24 away from the fixed column 32 through the inclined surface to slide. On one side of the partition 21, the partition 21 is pressed tightly by hand to keep the clamping claw 26 in contact with the fixing column 32. The fixed block 24 pulls the clamping claw 26 to move, and the outer side of the clamping claw 26 is in contact with When the cam 330 is in the closed position, the cam 331 is in the closed position, and the cam 332 is in the closed position, so that the cam 332 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position, and the cam 334 is in the closed position, so that the cam 333 is in the closed position, and the cam 336 is in the closed position, so that the cam 333 is in the closed position, and the cam 336 is in the closed position, so that the cam 333 is in the closed position, and the cam 336 is in the closed position, so that the cam 333 is in the closed position, and the cam 334 is in the closed position, so that the cam 333 is in the closed position, and the cam 336 ...

[0050] The valve at one end of the air pipe 51 is inflated by an air pump, so that gas enters the air pipe 51, causing the first air bag 58 and the second air bag 59 to expand. When the second air bag 59 expands, it contacts and wraps the outer wall of the partition 21, thereby reducing the entry of water vapor into the interior of the column 1 and preventing the inner side of the partition 21 from becoming moldy. After the air is fully inflated, the second worm 52 is rotated to drive the second worm gear 53 to rotate, thereby driving the second screw rod 55 to rotate and driving the slider 54 to move downward. When the first air bag 58 is inflated, the spring 56 will be compressed. During use, the air inside the first air bag 58 and the second air bag 59 will be lost and leaked. The compression potential energy of the spring 56 will push the pressure block 57 downward, thereby squeezing the first air bag 58. Under the connection of the air pipe 51, the second air bag 59 is kept in an inflated state, thereby ensuring the effect of isolating water vapor and ensuring the continuous operation of the second air bag 59. When inflating, it is necessary to drive the slider 54 upward to ensure that the first air bag 58 can expand.

[0051] During the disassembly process, the partition 21 is driven to move so that the mounting block 41 at one end is exposed, and the power supply is connected to the plug 441, thereby supplying power to the metal ring 442, so that the cutting wire 42 forms a loop and generates heat. The driving rod 431 is rotated by the handle 331, thereby driving the first bevel gear 432 and the second bevel gear 433 to rotate, driving the winding disk 434 to wind up the cutting wire 42, and the cutting wire 42 disengages from the mounting groove 45, bypasses the base 25, and cuts the foam glue. The cutting wire 42 uses an electric heating wire, which generates heat after being powered on, increasing the cutting ability of the foam glue, thereby facilitating the disassembly and separation of the partition 21, avoiding damage to the partition 21, and increasing utilization. The winding disk 434 is made of metal, which can prevent the heated cutting wire 42 from damaging it.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
