Description

Technical Field

[0001] The present invention relates to the technical field of decoration and renovation, and in particular to a method and device for constructing a large-span space suspended ceiling unit module. Background Art

[0002] The decoration and renovation of large public buildings are increasingly characterized by large spans, exceptional heights, and complex stepped forms. These factors present challenges during construction, including large scale, tight deadlines, a low degree of assembly, extensive overhead work, and high labor costs. Large lecture halls are particularly complex, with numerous interdisciplinary and overlapping tasks, including design and decoration, information technology, video conferencing, power and low-voltage systems, HVAC, and smoke exhaust. Furthermore, current aluminum ceilings present high installation requirements and strict flatness requirements, significantly impacting the overall appearance. Panel styles are also limited. Prefabricated modular components are often costly, time-consuming, prone to transport damage, and difficult to adapt to mechanical and electrical installation adjustments. Current traditional construction methods struggle to meet tight deadlines, and interdisciplinary pre-embedded components present positioning challenges and work interface demarcation issues. Furthermore, the extensive overhead routing of mechanical and electrical pipelines and supports, coupled with their multifunctionality, further compresses the space above the ceiling, making conventional modular installation difficult.

[0047] like Figures 1-19 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:

[0048] Step 1: Divide the ceiling into multiple unit modules 1 based on the ceiling shape, and draw a layout diagram of the unit modules 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 ensured, and on the other hand, the overall effect of the ceiling shape is ensured.

[0049] The electromechanical pipelines are comprehensively arranged using BIM technology based on the design drawings, the layout diagram of the unit module 1, and the ceiling steel frame 2. After the 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 brackets 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 to the bottom of the structural plate 8. The bottom end bolts are connected to the guide rail horizontal bars 2.1. The guide rail horizontal bars 2.1 are connected to the cross braces 2.2 with equal horizontal bolts to form a ceiling hanging steel frame system. Among them, 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.

[0050] Assemble the lifting unit 5 and the mobile lifting unit 6 in advance. The lifting 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 passes around 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.

[0051] Among them, a micro motor 5.3 is installed on the base 5.4 and is connected to the upper pulley 5.5. The micro motor 5.3 drives the upper pulley 5.5 to rotate, which plays a role in assisting lifting. The upper pulley 5.5 and the lower pulley 5.6 are provided with teeth that cooperate with the toothed belt 5.7.

[0052] 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 are 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 a connecting steel frame 7. The connecting steel frame 7 is assembled with steel sections with fixed-distance holes, and the steel sections are bolted to facilitate adaptation to different projects and the hoisting of unit modules 1 and electromechanical pipelines of different specifications. The design of the hoisting unit 5 takes into account the reduction of its own weight on the one hand, and the avoidance of conflict between the trolley and the cross brace 2.2 of the top ceiling steel frame 2 and the electromechanical pipeline position in the height direction on the other hand.

[0053] 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 achieve rod lengthening, which can be freely matched and assembled according to on-site conditions.

[0054] Step 2:

[0055] On the ground, the electromechanical pipelines are installed in advance on the support bracket 4 according to the construction unit 3, and then the mobile lifting unit 6 is installed on the side of the support bracket 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 bar 2.1 is moved to the corresponding construction unit 3 in place with the help of the laser plumb line 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 bracket 4 is connected and fixed with the structural plate 8. The connection between the mobile lifting unit 6 and the support bracket 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 interspersed.

[0056] 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 production 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 set on the front and back sides of the unit module 1, and four angle steel hangers 1.6 are set 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.

[0057] Connect the mobile lifting unit 6 through the connecting rod 6.3, place the assembled unit module 1 on the mobile lifting unit 6, and move the unit module 1 to the installation position through the mobile lifting unit 6. Use the toothed belt 5.7 to pass through the upper pulley 5.5 and the lower pulley 5.6 to lift it into place. Each time it is lifted, the unit module 1 needs to be lifted 200mm from the ground and checked. 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 in 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, move the lifting unit 5 forward to the next lifting position, and finally fix the eight angle steel hangers 1.6 on both sides of the unit module 1.

[0058] In the early stage of this application, a comprehensive layout planning is carried out, and the long-span electromechanical pipelines are divided into construction units 3 according to the supports and hangers 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 lifting, and the lifting unit 5 and the mobile lifting unit 6 are assembled for the lifting construction of the electromechanical pipelines and the unit module 1, and the unit module 1 is processed on site at the same time. After a part of the electromechanical pipeline construction is completed, the ceiling construction is interspersed when it reaches the water insertion point. The unit module 1 also uses the lifting unit 5 and the mobile lifting unit 6 to move and lift the processed unit module 1. The entire installation work is provided by a small mobile lifting vehicle to provide the construction personnel with an operating surface.
