Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to an overhanging operation platform with an airside extension. Background Art

[0002] During the construction process, due to the existence of overhanging structures, during external wall operations such as curtain wall construction and fireproof coating construction, since the construction site is airside, an operation platform extending outward needs to be erected to facilitate personnel to operate outside the overhanging structure. Currently, a relatively conventional solution is to set up overhanging I-beams and then erect steel pipe scaffolds to form a fixed operation platform. However, the erection of such an operation platform takes a long time, uses a large amount of materials, and is rather cumbersome. Therefore, more and more integral movable overhanging operation platforms are adopted on-site.

[0003] To solve the above problems, the Chinese patent with the application number 202211094733.7 discloses an overhanging operation platform. The disclosed overhanging operation platform includes a base, a counterweight, a vertical frame, overhanging beams, and a platform. Among them, the counterweight is configured on the base, and the vertical frame is detachably connected to the base; the number of overhanging beams is two, and they are detachably horizontally connected to the opposite sides of the vertical frame; the platform includes a shelf and a floorboard. The two sides of the shelf are respectively clamped at one end of the two overhanging beams away from the vertical frame, and the floorboard is lapped on the shelf to form a working platform for placing tools or for construction personnel to stand on. The Chinese patent with the application number 202211419210.5 discloses a cantilever type operation platform. The disclosed cantilever type operation platform includes a top bracket, a support frame body, and a bottom bracket that are detachably connected in sequence from top to bottom, as well as a support plate, a long jack, a short jack, and a counterweight; a cantilever support rod extends forward from the upper side of the front end of the support frame body; an inclined support rod is arranged on the lower side of the front end of the support frame body, and the upper end of the inclined support rod is fixedly connected to the cantilever support rod; a guardrail is arranged on the side of the top bracket, and a plurality of support plates are laid on the upper surface of the top bracket; a plurality of universal wheels are installed on the lower surface of the bottom bracket, and a counterweight part is arranged at the rear end of its upper surface, and a plurality of counterweights are arranged on the counterweight part; the long jack is arranged at the rear end of the support frame body and is in lifting cooperation with the support frame body; short jacks are arranged at both the front and rear ends of the bottom bracket, and the short jacks are in lifting cooperation with the bottom bracket.

[0034] Specific construction steps:

[0035] 1. Check the drawings

[0036] Obtain parameters such as the specific location and cantilever length of the structural cantilever part by checking the drawings.

[0037] 2. Site preparation

[0038] According to the workload of the structural cantilever part, prepare the corresponding number of cantilever operation platforms to meet the synchronous operation requirements. The operation platforms are welded and fabricated from the materials available on site, and the specific dimensions are designed according to the different cantilever lengths of the structure.

[0039] 3. Installation of the embedded ring 3

[0040] Determine the embedding location of the embedded ring 3 according to the length and width dimensions of the operation platform. Install the embedded ring 3 while binding the floor slab steel bars, and then pour the floor slab concrete.

[0041] 4. Fixing of the operation platform

[0042] Lift the operation platform through the handle 2021 of the support framework 12, making the overhead part 102 of the cantilever platform 1 tilt forward. Then, use the rollers 2011 at the bottom of the first support column 201 of the support framework 2 as a support for movement. After the operation platform reaches the designated operation location, first insert one side of the fixing part 2022 into the embedded ring 3 on that side until it reaches the bottom, ensuring that the fixing part 2022 on the other side can just align with the middle of the embedded ring 3 on that side. Then, move the entire operation platform towards that side to ensure that the lengths of the fixing parts 2022 extending out of the embedded ring 3 on both sides are the same. Finally, fill the gap between the embedded ring 3 and the second support column 202 of the support framework 2 with materials such as steel pipes to prevent the operation platform from shaking left and right, causing one side of the fixing part 2022 to run out of the embedded ring 3.

[0043] 5. Cantilever operation

[0044] After the operating platform is fixed, the operator climbs onto the cantilever platform 1 through the ladder 103 and walks to its overhead part 102 to carry out construction operations on the externally cantilevered part of the structure. When the operations at this part are completed and it is time to move to the next working location, simply remove the steel pipe stuck between the embedded ring 3 and the second support column 202. Then, move the operating platform until the fixing part 2022 on one side is disengaged from the embedded ring 3, and then take out the fixing part 2022 on the other side using the same steps. Finally, lift the handle 2021 to transfer the operating platform to the next working point, and fix the operating platform according to the operations in step 4.

[0045] 6. Removal of the operating platform

[0046] After all the operations on the cantilevered parts of the structure are completed, unload the operating platform and place it centrally according to the operations in step 5 above. Then, use a cutting machine to cut off the embedded ring 3 from the floor surface, and use a grinder to smooth the excess part.
