Description

Technical Field

[0001] The utility model relates to the technical field of suspended ceilings in steel structure workshops, in particular to a double-layer suspended ceiling installation system for clean workshops with steel structures. Background Art

[0002] For example, China Utility Model Patent Publication No. CN 219411471 U discloses a detachable ceiling system for a clean room, including: ceiling panels, ceiling keels and aluminum in the middle, the ceiling panels overlap the ceiling keels, and adjacent ceiling panels are connected through the aluminum in the middle; the ceiling keel includes: a keel body, a supporting arm and a connecting arm, the keel body connects the supporting arm and the connecting arm, and the supporting arm overlaps the ceiling panels. In the prior art, a single-layer ceiling of a steel structure factory building will result in a higher installation position for the air duct and a higher maintenance position for workers. If the suspension rod is extended to lower the height, the suspension rod is too long and is more likely to shake. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a double-layer ceiling installation system for a steel structure clean workshop, which can facilitate the installation of the double-layer ceiling, lower the installation height of the air duct, reduce the maintenance height of workers, and reduce shaking.

[0004] In order to solve the above problems, a double-layer ceiling installation system for a steel structure clean workshop is adopted, which includes:

[0005] Upper ceiling panels;

[0006] The "X"-shaped connector has its opening facing downward and is fixedly arranged at the four corners of the upper ceiling board;

[0007] The upper fixing plate is U-shaped with the opening facing downwards.

[0008] The main keel of the transfer layer is horizontal and fixed at intervals on both inner sides of the upper fixed plate;

[0009] The lower layer suspension rod, the upper end of which passes through the upper fixing plate and is tightened on the upper fixing plate by a first nut, passes between the two transfer layer main keels and extends downward;

[0010] The lower fixing plate is U-shaped with the opening facing upwards, is closely attached to the bottom and outer side of the main keel of the transfer layer, is passed through by the lower layer suspension rod, and is tightened from below by the second nut;

[0011] An adjusting screw rod is fixedly connected to the lower end of the lower suspension rod;

[0012] A lower ceiling board keel assembly is fixed to the lower end of the adjusting screw;

[0013] A lower ceiling panel is fixed below the keel assembly of the lower ceiling panel;

[0014] The air duct is fixedly arranged on the keel assembly of the lower ceiling panel.

[0015] With such a structure, the upper horizontal surface of the "X"-shaped connector increases the force-bearing area, makes the force uniform, and reduces shaking. The upper fixed plate and the lower fixed plate clamp the transition layer keel in the middle, making the installation of the transition layer keel more stable. The adjusting screw facilitates height adjustment. The air duct is installed on the keel assembly of the lower ceiling panel to reduce the installation height, which reduces the maintenance height and is convenient for workers to inspect.

[0016] As a further improvement of the utility model, a transfer layer main keel filling plate is arranged between two opposite transfer layer main keels respectively fixed on two lower layer suspension rods.

[0017] With such a structure, the main keel filling plate of the transfer layer further limits the lateral displacement relative to the main keel of the transfer layer, further reducing the overall shaking.

[0018] As a further improvement of the utility model, the folded edges on both sides of the "X"-shaped connecting piece are fixed to the upper fixing plate by fixing screws.

[0019] As a further improvement of the utility model, bolts are passed through the four corners of the upper ceiling plate and the "X"-shaped connectors are fixed.

[0020] As a further improvement of the utility model, the lower ceiling panel adopts a steel plate painted blind panel.

[0021] As a further improvement of the utility model, the adjusting screw includes a square tube and a screw rod. The lower end of the lower suspension rod passes through the square tube and is tightened by the third nut; the upper end of the screw rod passes through the square tube and is tightened by the fourth nut.

[0022] As a further improvement of the utility model, a 30° inclined tie rod is provided between the main keel of the conversion layer and the keel assembly of the lower ceiling panel.

[0023] As a further improvement of the utility model, the main keel filler plate of the conversion layer is connected to the purlin on the side.

[0024] As a further improvement of the utility model, a fan filter unit (FFU) is installed at the bottom of the air duct.

[0025] The main beneficial effects of the utility model are: 1. All connecting components are welded without welding, the installation and connection are tight and the installation and disassembly are simple; 2. The overall shaking is small, which can effectively reduce the air leakage rate between the ceiling panels; 3. The double-layer ceiling is convenient for layered construction, which effectively reduces the collision problem of multi-professional construction processes to speed up the overall construction progress.
