Description

Technical Field

[0001] This invention relates to the field of construction, and further to a prefabricated ceiling panel and building. Background Technology

[0002] Prefabricated ceilings belong to the modular integrated ceiling system. All components are prefabricated in a standardized manner in the factory and then directly assembled on the construction site. The entire system mainly consists of standardized units such as load-bearing keel, decorative panels, and special connecting accessories. Compared with traditional on-site wet ceiling construction, prefabricated ceilings have the significant advantages of fast assembly speed and significantly shortened construction period. At the same time, the components are disassembled and reassembled, making later inspection, renovation and modification operations simple.

[0003] In existing technologies, metal embedded plates are usually pre-embedded in the preset position during the pouring of the concrete roof slab of the building. Then, the top of the tie rod is connected and fixed to the metal embedded plate by welding. Welding is prone to weld safety hazards, damages the anti-corrosion layer of the component and causes rust. The welding operation is large-scale and the weld quality is difficult to guarantee. This not only increases the construction and maintenance costs, but also fails to meet the requirements of modern buildings for flexible functions and efficient construction.

[0004] Traditional prefabricated ceilings use standardized components with fixed and unadjustable specifications (sizes), resulting in insufficient flexibility. When the size conditions at the construction site do not match the standard components, on-site cutting (cutting ceiling panels and / or frames) is still required to meet the installation needs. This not only makes installation cumbersome and complicated, but also requires high skill from craftsmen, and affects construction efficiency and the aesthetics of the ceiling.

[0005] Traditional prefabricated ceiling panels, such as aluminum panels, are fixed with exposed self-tapping screws, which can easily lead to stress cracking of the panel surface, screw corrosion and contamination of the surface, stripping and damage to the panels during disassembly and assembly, and low reusability. Overall, traditional prefabricated ceiling components have poor adaptability and flexibility, making it difficult to meet the construction needs of modern buildings for efficient construction, flexible modification and component recycling.

[0047] refer to Figures 1 to 8 This application provides a prefabricated ceiling panel 100, which includes an embedded part 10, a decorative panel 20, and a suspension rod 30. The embedded part 10 includes a base plate 11, an anchor rod 12, and a connecting sleeve 13. The first end 121 of the anchor rod 12 is connected to the base plate 11, and the second end 122 extends away from the base plate 11 and is adapted to be embedded in the concrete ceiling slab 200. The connecting sleeve 13 is installed on the base plate 11 and has an installation space 130. The end of the connecting sleeve 13 away from the second end 122 of the anchor rod 12 has an installation opening 131 communicating with the installation space 130.

[0048] Preferably, the concrete roof slab 200 is, for example, but not limited to, the top wall of a building interior, and the decorative panel 20 is adapted to be disposed below the concrete roof slab 200 at a predetermined distance from the concrete roof slab 200.

[0049] The hanger rod 30 is adapted to be disposed between the concrete roof slab 200 and the decorative panel 20. The top of the hanger rod 30 is adapted to be detachably installed within the installation space 130 of the connecting sleeve 13, and the bottom of the hanger rod 30 is adapted to be connected to the decorative panel 20. That is, one end of the hanger rod 30 is connected to the concrete roof slab 200, and the other end is connected to the decorative panel 20. The decorative panel 20 can be fixedly installed below the concrete roof slab 200 by means of the hanger rod 30.

[0050] In this application, the embedded part 10 is not only provided with anchor rod 12, but also with connecting sleeve 13. During use, the embedded part 10 needs to be embedded in the preset position of the concrete top plate 200. When connecting the hanger 30 to the embedded part 10, it is only necessary to insert the top end of the hanger 30 into the installation space 130 of the connecting sleeve 13. The operation is simple and the installation is convenient.

[0051] Preferably, the top of the lifting rod 30 is generally round, and the end of the lifting rod 30 connected to the connecting sleeve 13 and the inner wall of the connecting sleeve 13 are provided with mutually compatible threads. The lifting rod 30 and the connecting sleeve 13 are detachably connected by the threaded connection. During assembly, the lifting rod 30 can be installed on or removed from the connecting sleeve 13 by rotating the lifting rod 30 relative to the connecting sleeve 13. In some modified embodiments, the top end of the lifting rod 30 can also be detachably connected to the connecting sleeve 13 by snap-fit. As long as the detachable connection between the lifting rod 30 and the connecting sleeve 13 can be achieved, the specific connection method between the lifting rod 30 and the connecting sleeve 13 should not constitute a limitation of this application.

[0052] refer to Figure 1 and Figure 2 The anchor rod 12 includes a first anchor rod 123 and a second anchor rod 124, which are disposed on the base plate 11 at a predetermined distance from each other. The connecting sleeve 13 is disposed between the first anchor rod 123 and the second anchor rod 124, and the connecting sleeve 13, the first anchor rod 123, and the second anchor rod 124 are disposed on the same side of the base plate 11. The base plate 11 has a communicating opening 110 corresponding to the mounting opening 131 at the position corresponding to the connecting sleeve 13.

[0053] refer to Figure 3 The number of the first anchor rod 123 and the second anchor rod 124 are two each, and the total number of anchor rods 12 is four. The connecting sleeve 13 is located at the center of the four anchor rods 12.

[0054] The top end of the hanger 30 is adapted to pass through the communication opening 110 on the base plate 11 and the mounting opening 131 of the connecting sleeve 13 into the mounting space 130 to achieve connection with the connecting sleeve 13.

[0055] There are two anchor rods 12. The first anchor rod 123 and the second anchor rod 124 are located on both sides of the connecting sleeve 13, which can increase the uniformity of force and improve the stability of the connection between the embedded part 10 and the concrete top plate 200.

[0056] In some modified embodiments, both the first anchor rod 123 and the second anchor rod 124 are inclined at a predetermined angle relative to the base plate 11. Specifically, the length extension directions of the first anchor rod 123 and the second anchor rod 124 are both inclined at a certain angle to the length extension direction of the hanger 30. When the hanger 30 is subjected to a vertical force applied by the decorative panel 20, the inclined first anchor rod 123 and the second anchor rod 124 will have a greater bonding force with the concrete top slab 200, improving the stability of the bond between the anchor rod 12 and the concrete top slab 200.

[0057] refer to Figure 1 and Figure 2 The embedded part 10 further includes a limiting block 14 disposed on the side surface of the second end 122 of the anchor rod 12. When the anchor rod 12 is embedded in the concrete top slab 200, the limiting block 14 extends outward from the outer surface of the anchor rod 12 by a certain length, and can be engaged inside the concrete top slab 200, thereby improving the stability of the anchor rod 12 when embedded in the concrete top slab 200.

[0058] refer to Figure 5 In one modified embodiment, the anchor rod 12 and the connecting sleeve 13 are integrally formed, and the base plate 11 has a communicating opening 110 corresponding to the installation opening 131 at the position of the anchor rod 12. In this modified embodiment, the integral formation of the anchor rod 12 and the connecting sleeve 13 reduces the space occupied by the pre-embedded part 10 in the concrete roof slab 200 when it is embedded in the concrete roof slab 200, thus helping to maintain the overall structural stability of the concrete roof slab 200. On the other hand, when the top of the hanger 30 is installed in the installation space 130, the tension of the decorative panel 20 on the hanger 30 will be directly transmitted to the anchor rod 12. Since the anchor rod 12 is directly embedded in the concrete roof slab 200, the number of points where the force is applied can be reduced, improving the stability and load-bearing capacity of the pre-embedded part 10 when it is embedded in the concrete roof slab 200.

In this modified embodiment, the top of the hanger rod 30 or the entire hanger rod 30 is in the shape of an angle steel, and the top of the hanger rod 30 can be stacked with the second transition plate 42 of the transition plate 40. In this modified embodiment, the first adapter plate 41 and the second adapter plate 42 of the adapter plate 40 are set at approximately 90°. The first adapter plate 41 and the second adapter plate 42 allow the hanger 30 and the connecting sleeve 13 to be staggered in the vertical direction, which facilitates the operation of the first fixing member 51 to fix the first adapter plate 41 and the connecting sleeve 13.
