[0019] like Figure 1-Figure 19 As shown, the present invention discloses a construction method and device for a large-span space ceiling partition unit module 1, the method comprising the following steps: Step 1: Divide the ceiling into multiple unit modules 1 based on the ceiling shape, and draw a layout diagram of the unit module 1. Arrange electromechanical lamps, fire sprinklers, vents, etc. on the layout diagram. The lamps and fire sprinklers are evenly and symmetrically arranged on the unit modules 1, and the vents are evenly and symmetrically arranged on the cover plates between the unit modules 1. On the one hand, uniform lighting is guaranteed, and on the other hand, the overall effect of the ceiling shape is guaranteed.

[0020] The electromechanical pipelines are comprehensively arranged using BIM technology based on design drawings, unit module 1 layout drawings, and ceiling steel frames 2. After BIM modeling is completed, the on-site situation is reviewed and then adjusted according to the actual on-site situation; multiple construction units 3 are divided according to the support and hanger 4 of the electromechanical pipelines, and the electromechanical pipeline construction sequence is formulated according to the arrangement sequence of the construction units 3. At the same time, the ceiling steel frame 2 is constructed as a guide rail system. The ceiling steel frame 2 includes hanging columns 2.4, reverse diagonal braces 2.3, guide rail horizontal bars 2.1, and cross braces 2.2. The hanging columns 2.4 are arranged at equal intervals and fixed at the bottom of the structural plate 8. The bottom end bolts are connected to the guide rail horizontal bars 2.1, and the guide rail horizontal bars 2.1 are connected to the cross braces 2.2 with horizontally equidistant bolts to form a ceiling hanging steel frame system, wherein the reverse diagonal braces 2.3 are connected between the structural plate 8 and the hanging columns 2.4, and the guide rail horizontal bars 2.1 are T-shaped steel horizontal bars.

[0021] Assemble the hoisting unit 5 and the mobile lifting unit 6 in advance. The hoisting unit 5 includes a roller assembly and a lifting assembly. The roller assembly includes a driving wheel group 5.1 and a driven wheel group 5.2. The driving wheel group 5.1 is transmission-connected to the micromotor 5.3. The driving wheel group 5.1 and the driven wheel group 5.2 each include a pair of rollers, and the opposite sides of the rollers are installed on the base 5.4; the lifting assembly includes an upper pulley 5.5, a lower pulley 5.6 and a toothed belt 5.7. The upper pulley 5.5 is installed between the two bases 5.4 and located below the roller assembly, and is used as a fixed pulley. The lower pulley 5.6 is used to be installed on the unit module 1 and used as a movable pulley. One end of the toothed belt 5.7 is connected to the upper pulley 5.5, and the other end bypasses the lower pulley 5.6 and the upper pulley 5.5, and drives the lower pulley 5.6 to move upward through the toothed belt 5.7.

[0022] The base 5.4 is provided with a micro motor 5.3 which is connected to the upper pulley 5.5. The micro motor 5.3 drives the upper pulley 5.5 to rotate, thereby assisting the lifting. The upper pulley 5.5 and the lower pulley 5.6 are provided with teeth which match the toothed belt 5.7.

[0023] During hoisting, a four-point synchronous hoisting method is adopted to ensure that the components can be hoisted to a position close to the ceiling steel frame 2 for installation. A group of hoisting units 5 is installed corresponding to each hoisting point. The two groups of hoisting units 5 along the travel direction of the hoisting units 5 are connected by connecting steel frames 7. The connecting steel frames 7 are assembled with steel sections with fixed-distance holes. The steel sections are bolted to facilitate the hoisting of unit modules 1 and electromechanical pipelines of different projects and different specifications. The design of the hoisting unit 5 takes into account the reduction of its own weight on the one hand, and avoids the conflict of the trolley in the height direction with the cross brace 2.2 of the top ceiling steel frame 2 and the position of the electromechanical pipelines.

[0024] The mobile lifting unit 6 includes a base 6.1 and a universal wheel 6.2 installed on the bottom surface of the base 6.1. The universal wheel 6.2 has a built-in locking function. The lower pulley 5.6 is installed on the outer side of the base 6.1. The mobile lifting unit 6 can be directly installed on the component for lifting, or two groups of mobile lifting units 6 distributed along the length direction of the cross brace 2.2 can be connected by a connecting rod 6.3, and the component is placed on the connecting rod 6.3 for lifting. The cross section of the connecting rod 6.3 is C-shaped, and bolt holes are evenly spaced on the side. The connecting rods 6.3 are connected by C-shaped connectors to lengthen the rods, which can be freely matched and assembled according to the on-site conditions.

[0025] Step 2: On the ground, the electromechanical pipelines are installed in advance on the support and hanger 4 according to the construction unit 3, and then the mobile lifting unit 6 is installed on the side of the support and hanger 4. The construction unit 3 of the assembly number is moved to the installation position by the mobile lifting unit 6. The installation position is positioned, and the lifting unit 5 on the guide rail horizontal rod 2.1 is moved to the corresponding construction unit 3 in place with the help of a laser plumb meter to wait for lifting and installation. The mobile lifting unit 6 is driven to rise to the installation position by pulling the toothed belt 5.7, and then the support and hanger 4 is connected and fixed with the structural plate 8. The connection between the mobile lifting unit 6 and the support and hanger 4 is released, and the lifting unit 5 is moved to the next installation position. The mobile lifting unit 6 transports and lifts the next construction unit 3; after installing a section of construction unit 3, the construction unit 3 module 1 is inserted.

[0026] Step 3: Draw a processing drawing of the unit module 1 according to the layout diagram, set up a processing area on the ground on site, and carry out prefabrication and processing of the unit module 1 and the sealing plate between the unit modules 1. The unit module 1 includes a secondary keel 1.1, a flame retardant board 1.2, a gypsum board 1.3 and an inorganic coating layer 1.4 arranged in sequence from top to bottom, and a transverse keel 1.5 is connected between the secondary keels 1.1; angle steel hangers 1.6 are installed on the end faces of the unit modules 1. In the embodiment of the present application, two angle steel hangers 1.6 are arranged on the front and rear sides of the unit module 1, and four angle steel hangers 1.6 are arranged on the left and right sides; in addition, the unit module 1 also includes reserved openings for electromechanical lighting points and inspection ports, and the sealing plate includes reserved openings for ventilation and smoke exhaust ports. The mobile lifting unit 6 is connected through the connecting rod 6.3, the assembled unit module 1 is placed on the mobile lifting unit 6, and the unit module 1 is moved to the installation position by the mobile lifting unit 6, and the toothed belt 5.7 is used to pass through the upper pulley 5.5 and the lower pulley 5.6 for lifting in place. Each time the unit module 1 is lifted, it is necessary to lift it 200mm off the ground and then check it. After the inspection is correct, it is officially lifted to the ceiling position. After it is in place, the four angle steel hangers 1.6 of the front and rear rows of the unit module 1 are fixed with the ceiling rods. After the mobile lifting unit 6 is placed on the ground, the lifting unit 5 is moved forward to the next lifting position, and finally the eight angle steel hangers 1.6 on both sides of the unit module 1 are fixed.

[0027] In the early stage of this application, comprehensive layout planning is carried out, and the long-span electromechanical pipelines are divided into construction units 3 according to the support brackets 4. Similarly, the long-span ceiling shape is also divided into unit modules 1 for construction. During construction, the ceiling steel frame 2 is first constructed as a guide rail system for hoisting, and the hoisting unit 5 and the mobile lifting unit 6 are assembled for the hoisting construction of the electromechanical pipelines and unit modules 1, and the unit modules 1 are processed on site at the same time. After a part of the electromechanical pipeline construction is completed, when it reaches the water flow insertion point, the ceiling construction is interspersed. The unit module 1 also uses the hoisting unit 5 and the mobile lifting unit 6 to move and hoist the processed unit module 1. The entire installation work is provided by a small mobile lifting vehicle to provide a working surface for the construction personnel.
