Description

Technical Field

[0001] This application relates to the field of architectural decoration engineering, and in particular to a prefabricated ceiling conversion layer. Background Technology

[0002] In high-rise public buildings, the ceiling transition layer serves as a transitional structural layer connecting the main building structure and the ceiling system. It primarily addresses issues such as height differences between the building structure and the ceiling, load transfer, and spatial pipeline integration. In related technologies, ceiling transition layers in high-rise public buildings typically employ steel structure welding processes. Workers must erect scaffolding support systems on-site and fix the suspension rods to the floor slab through on-site welding. Regarding the aforementioned technologies, the inventors believe that the above-mentioned ceiling construction is quite difficult and requires custom-made rods of different lengths for different floor heights, resulting in poor adaptability. Utility Model Content

[0003] This application provides a prefabricated ceiling transition layer, which is easy to assemble and has good adaptability.

[0004] This application provides a prefabricated ceiling transition layer using the following technical solution:

[0005] A prefabricated ceiling transition layer includes four main hangers vertically arranged at the bottom of a floor slab and horizontal hangers installed at the lower ends of two adjacent main hangers. Each main hanger includes a first hanger, a second hanger, and an adjusting sleeve connecting the first and second hangers along a direction away from the floor slab. The adjusting sleeve has an adjusting through-hole penetrating its upper and lower end faces. The bottom of the first hanger has a first telescopic portion that slides upwards and downwards within the adjusting through-hole. A first locking structure is provided between the first telescopic portion and the adjusting sleeve. The top of the second hanger has a second telescopic portion that slides upwards and downwards within the adjusting through-hole. A second locking structure is provided between the second telescopic portion and the adjusting sleeve.

[0006] By adopting the above technical solution, when arranging the prefabricated ceiling transition layer, the operator first vertically fixes the four main hangers to their respective positions at the bottom of the floor slab. Then, the relative distance between the first telescopic part of the first hanger and the adjusting sleeve, and between the adjusting sleeve and the second telescopic part of the second hanger, is adjusted so that the length of the main hanger can be adapted to the floor height of the building. Finally, a horizontal hanger is installed at the lower end of the main hanger, thereby realizing the construction of the ceiling frame. By sliding the first and second telescopic parts up and down in the adjusting through hole and adjusting them to the appropriate position, and by using the first and second locking structures, the first and second telescopic parts can be locked in the adjusting sleeve respectively, allowing for flexible adjustment of the length of the main hanger, thereby improving the ease of ceiling assembly and adaptability.

[0007] Optionally, the first locking structure includes a plurality of first through holes that penetrate the inner and outer surfaces of the adjusting sleeve and are spaced apart along the height direction, a first locking hole that is opened in the first telescopic part and corresponds to the first through hole, and a first locking screw that is threadedly engaged with the first locking hole.

[0008] By adopting the above technical solution, the first telescopic part can slide up and down in the adjusting sleeve. After the first locking hole of the first telescopic part is aligned with one of the first through holes, the first locking screw is used to lock it in place, so that the first telescopic part is locked in a suitable position in the adjusting sleeve. This allows the length of the main hanger to be flexibly adjusted to adapt to different installation requirements, which helps to improve the adaptability of the ceiling to different floor heights.

[0009] Optionally, the second locking structure includes a plurality of second through holes that penetrate the inner and outer surfaces of the adjusting sleeve and are spaced apart along the height direction, a second locking hole that is opened in the second telescopic part and corresponds to the second through hole, and a second locking screw that is threadedly engaged with the second locking hole.

[0010] By adopting the above technical solution, the second telescopic part can slide up and down in the adjusting sleeve. After the second locking hole of the second telescopic part is aligned with one of the second through holes, the first locking screw is used to lock it in place, so that the second telescopic part is locked in a suitable position in the adjusting sleeve. This allows the length of the main hanger to be flexibly adjusted to adapt to different installation requirements, which helps to improve the adaptability of the ceiling to different floor heights.

[0011] Optionally, the cross-section of the adjusting through hole is L-shaped, the cross-section of the first telescopic part is an L-shaped cross-section adapted to the adjusting through hole, and the cross-section of the second telescopic part is an L-shaped cross-section adapted to the adjusting through hole.

[0012] By adopting the above technical solution, setting an adjustment through hole with an L-shaped cross section, a first telescopic part, and a second telescopic part, the first telescopic part and the second telescopic part are less likely to move when sliding in the adjustment through hole, which helps to improve the stability of the main boom height adjustment.

[0013] Optionally, the upper end of the first hanger has a first mounting component for installing the main hanger to the bottom of the floor slab; the first mounting component includes a first angle steel with one end connected to the upper end of the first hanger and a mounting bolt for locking the other end of the first angle steel to the bottom of the floor slab; the first angle steel has a mounting screw hole for locking by the mounting bolt.

[0014] By adopting the above technical solution, the specific structure of the first mounting component is disclosed. With the cooperation of the first angle steel and the mounting bolts, the mounting screw holes on the angle steel facilitate the locking of the mounting bolts, thus realizing the convenient and stable installation of the main hanger at the bottom of the floor slab.

[0015] Optionally, the horizontal suspension rod includes two transverse suspension rods and two longitudinal suspension rods arranged opposite each other, and the lower end of the second suspension rod has a horizontal connector for detachable installation at both ends of the transverse suspension rods and the longitudinal suspension rods.

[0016] By adopting the above technical solution, horizontal and longitudinal hangers are used as horizontal hangers to form a frame structure to improve stability. Horizontal connectors enable the horizontal hangers and the second hanger to be detachably installed, facilitating assembly and adjustment.

[0017] Optionally, the horizontal connector includes an outer plate fixed to the lower end of the second rod, two inner plates rotatably mounted on both ends of the outer plate, and two pivots arranged at both ends of the outer plate for rotatably mounting the two inner plates; a horizontal groove is formed between the outer plate and the inner plate for sliding the horizontal rod, and the inner plate has a magnetic attraction structure for fixing the horizontal rod in the horizontal groove.

[0018] By adopting the above technical solution, the specific structure of the horizontal connector is disclosed. The horizontal slide groove is formed by the outer side plate, the rotatable inner side plate and the rotating shaft, which realizes the sliding arrangement of the horizontal hanger and the horizontal connector. The magnetic attraction structure of the inner side plate can fix the horizontal hanger in the horizontal slide groove, realize the assembly of the prefabricated ceiling conversion layer, and improve the flexibility and adaptability of the horizontal hanger in disassembly and assembly.

[0019] Optionally, the magnetic attraction structure includes an arrangement groove formed on the inner side plate facing the horizontal slide groove and a magnetic attraction element that fits into the interior of the arrangement groove.

[0020] By adopting the above technical solution, the specific structure of the magnetic suction structure is further disclosed. An arrangement groove is opened on the side of the inner plate facing the horizontal slide groove, and a magnetic suction component is attached inside. The magnetic force of the magnetic suction component can be used to fix the horizontal rod in the horizontal slide groove, thereby facilitating the installation and disassembly of the horizontal connecting parts at both ends of the horizontal rod.

[0021] Optionally, the number of arrangement slots is two and they are symmetrically arranged on the side of the inner side plate facing the horizontal slide groove, and the magnetic suction element is provided in both arrangement slots.

[0022] By adopting the above technical solution, the magnetic attraction components installed in the two symmetrically arranged slots help to enhance the attraction force on the horizontal hanger, making the horizontal hanger more firmly fixed in the horizontal slide.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A prefabricated ceiling transition layer, comprising four main hangers vertically arranged at the bottom of the floor slab and horizontal hangers installed at the lower ends of two adjacent main hangers; when arranging the prefabricated ceiling transition layer, the operator first vertically fixes the four main hangers one by one to the corresponding positions at the bottom of the floor slab, then adjusts the relative distance between the first telescopic part of the first hanger and the adjusting sleeve, and between the adjusting sleeve and the second telescopic part of the second hanger, so that the length of the main hanger can be adapted to the floor height of the building, and finally installs the horizontal hangers at the lower ends of the main hangers, thereby realizing the construction of the ceiling frame and improving the ease of ceiling assembly and adaptability;

[0025] 2. By setting an adjustment through hole with an L-shaped cross section, a first telescopic part, and a second telescopic part, the first telescopic part and the second telescopic part are less likely to move when sliding in the adjustment through hole, which helps to improve the stability of the main boom height adjustment;

[0026] 3. By setting a horizontal connector at the lower end of the main hanger, the horizontal connector forms a horizontal groove through the outer side plate, the rotatable inner side plate and the rotating shaft, realizing the sliding arrangement of the horizontal hanger and the horizontal connector. The magnetic structure of the inner side plate can fix the horizontal hanger in the horizontal groove, realizing the assembly of the prefabricated ceiling conversion layer and improving the flexibility and adaptability of the horizontal hanger in assembly and disassembly.
