[0030] A method for installing an integrated ceiling that is easy to install, for installing the integrated ceiling that is easy to install, comprises the following steps: Step 1: Treat the ceiling at the construction site; Step 2: Carry out hanging construction under the ceiling of the construction site; Step 3: Assemble the integrated ceiling and match the integrated ceiling with the hanging accessories.
[0031] In the present invention, step one includes: firstly, checking the flatness and firmness of the ceiling at the construction site, leveling the uneven areas to ensure that the ceiling surface can provide a stable foundation for the subsequent suspended ceiling installation, and repairing the holes, cracks and other defects on the ceiling to prevent safety hazards or affect the installation effect of the suspended ceiling during the installation process, and finally cleaning the dust and debris on the ceiling surface to ensure that the installation area is clean and tidy so that the pendants can be firmly attached to the ceiling, thereby improving the stability and reliability of the suspended ceiling installation.
[0032] In the present invention, step two includes: according to the design layout and size requirements of the suspended ceiling, accurately mark the installation position of the hanger on the ceiling, use appropriate tools to fix the hanger on the ceiling, ensure that the hanger is firmly installed and the levelness meets the requirements, and the spacing between the hangers should be uniform to ensure that the suspended ceiling is evenly stressed after installation to avoid local sinking or deformation. During the installation of the hanger, pay attention to checking the quality and integrity of the hanger. Defective or damaged hangers should be replaced in time to ensure that each hanger can normally perform its load-bearing function and provide protection for the safe installation of the suspended ceiling.
[0033] In the present invention, step three includes: first, assemble the main support member 2 with the side support member 1 3 and the side support member 2 4: take out a plurality of main support members 2, and install the side support member 1 3 by matching its protrusion 1 with the groove 1 on the side of the main support member 2, ensuring that the protrusion 1 is completely embedded in the groove 1, so that the side support member 1 3 is tightly connected to the main support member 2, and in the same way, install the side support member 2 4 by matching its protrusion 2 with the groove 2 on the other side of the main support member 2, and then insert the protrusion 3 6 of the side support member 2 4 into the groove 3 of the side support member 1 3 on the side of the adjacent main support member 2 to ensure the stability and integrity of the entire support frame.
[0034] Secondly, assemble the adjusting mechanism 5 and the main support member 2: put the slider 7 of the adjusting mechanism 5 into the slide groove 1 above the main support member 2, and ensure that the slider 7 can slide smoothly in the slide groove 1, and then adjust the position of the slider 7 according to the actual installation requirements, so that it is in a suitable relative position in the slide groove 1 of the main support member 2, and then fix the slider 7 to the main support member 2 through a detachable connection method (such as bolt connection, snap connection, etc.) to prevent the slider 7 from being displaced during subsequent use. After the slider 7 is fixed, the construction personnel drive the rotating shaft 19 to drive the adjusting frame 10 to rotate, so that the adjusting frame 10 is perpendicular to the slider 7. After the rotation is completed, put the fixing member 11 into the slide groove 3 of the connecting member 8, and make the fixing protrusion of the fixing member 11 cooperate with the fixing groove of the rotating shaft 9, and then fix the fixing member 11 to the connecting member 8 through a detachable connection method.
[0035] Adjust the height component: The construction personnel can drive the rotating shaft 2 12 to rotate by turning the handle 1, and then the gear 13 drives the rack 14 to move up and down to realize the function of adjusting the height of the ceiling. After adjusting the appropriate height, the construction personnel turn the handle 2 to make the screw 18 drive the protrusion 4 17 to move closer to the rotating shaft 2 12, so that the protrusion 4 17 cooperates with the groove 4 of the rotating shaft 2 12, that is, the "W"-shaped tooth under the protrusion 4 17 is tightly matched with the groove 8, thereby enhancing the fixing effect and preventing it from rotating during use and affecting the stability of the ceiling height.
[0036] Assemble the support plate 22: the construction personnel drive the rotating shaft 3 to rotate through the connecting plate 20, so that the connecting plate 20 is perpendicular to the side of the adjustment frame 10, take the support plate 22, and match the slots on both sides of it with the ends of the connecting plate 20 on the adjacent adjustment mechanism 5, so that the support plate 22 can be stably placed on the connecting plate 20, and then fix the support plate 22 to the connecting plate 20 through a detachable connection method (such as pin connection, snap connection, etc.) to ensure that the support plate 22 will not fall off during use, thereby providing stable support for the ceiling.
[0037] The suspended ceiling cooperates with the hangers under the ceiling: the hanging ring 15 above the adjustment mechanism 5 is connected with the hangers under the ceiling to ensure that each hanging ring 15 is firmly connected to the hanger and the overall levelness of the suspended ceiling frame meets the requirements. Pick up the suspended ceiling panel 1, and cooperate the protrusion five 26 above it with the groove five 23 under the main support 2, the protrusion six 27 with the groove six 25 under the side support one 3, and the protrusion seven 28 with the groove seven 24 under the side support two 4, so that the suspended ceiling panel 1 can be tightly clamped under the main support 2, the side support one 3 and the side support two 4. During the installation process, care should be taken to avoid collision between the suspended ceiling panel 1 and other components to cause damage. At the same time, ensure that the suspended ceiling panel 1 is installed flat, tightly spliced, and without obvious gaps to ensure the beauty and use effect of the suspended ceiling.
