[0002] Generally, the protective operating frames of high-rise buildings during the main structure construction mostly use attached lifting scaffolding, which can be lifted layer by layer as the main structure construction progresses. Attached lifting scaffolding has the advantages of safety, reliability and good protection effect. However, after the dismantling and unloading of the bottom layer of templates, this construction method leaves little time for the construction process in the air-conditioning unit, and basically no working time. For this reason, it is necessary to use the method of hanging basket construction to complete the construction work of the process in the air-conditioning unit. However, the hanging basket construction can only be carried out after the hanging basket scaffolding for the exterior wall operation is installed, and it will overlap with the exterior wall insulation and exterior finishing construction, forming mutual interference, which not only affects the construction period, but also makes construction inconvenient, and cannot avoid the problem of idle work of installation workers during the main structure construction.

The same reference numerals are used to represent the same parts.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-2 , the preferred embodiments of the utility model are further described in detail:

[0023] like Figure 1-2 As shown, a preferred light and simple external scaffolding of the utility model includes an operating platform 1, a load-removing rope 9 and a safety protection rope 10, wherein the operating platform 1 includes two main beams 101 made of 60 angle steel, and the two main beams 101 are connected and fixed by a plurality of secondary beams 102 made of 40 flat steel arranged at intervals, and the secondary beams 102 and the main beams 101 are fixedly connected by welding to form a rectangular frame, and the top of the rectangular frame is fully covered with steel plate mesh as a platform plate 103, one end of the operating platform 1 is fixed to the recessed bay window of the main structure 8 by a locking support 4 and a limit top support leg 5, and the other end is extended to the working area of ​​another main structure 8 as a cantilever end, and a protective fence 2 is arranged at the periphery of the operating platform 1;

[0024] The locking support 4 includes a locking beam 401 and a tie end block 402 made of 60 angle steel. The locking beam 401 is horizontally arranged on the inner cantilever plate of the bay window of the main structure 8, and its outer end is fixedly connected to the operating platform 1, and its inner end is fixedly connected to the tie end block 402. In order to ensure the structural strength, the main beam 101 of the operating platform 1 is preferably used as the locking beam 401, and a secondary beam 102 can also be added to the inner end of the locking beam 401 to improve the integrity of the entire frame. The tie end block 402 is L-shaped, and the L-shaped tie end block 402 is stuck at the inner edge of the inner cantilever plate of the bay window of the main structure 8 in a hooked and tied manner;

[0025] The position-limiting top support leg 5 is passed through the locking beam 401 of the locking support 4, and its bottom end is against the top surface of the inner cantilever plate of the bay window of the main structure 8, so as to support the locking beam 401 from the top surface of the inner cantilever plate of the bay window of the main structure 8, and cooperate with the tie end 402 to clamp the inner cantilever plate of the bay window of the main structure 8;

[0026] The bottom end of the unloading rope 9 is fixed to the pull ring 7 at the front end of the operating platform 1, the front end of the safety rope 10 is fixed to the operator at the operating platform 1, and the rear ends of the unloading rope 9 and the safety rope 10 are fixed to the pull ring 7 of another set of locking supports 4, and the locking supports 4 with pull rings 7 are fixed to the inner cantilever board of the bayonet window of the main structure 8 at the upper position of the operating platform 1 through the limit top support legs 5;

[0027] Taking into account the problem that the concrete structural surface may be uneven, in order to ensure that the fixed end of the operating platform 1 can be stably rooted, it is advisable to add several groups of limit top support legs 5 on the locking beam 401. On the one hand, it can increase the support force and ensure the stability of the tie at the tie end stop 402. On the other hand, it can also reduce the pressure on the concrete structural surface to avoid damage to the structural surface of the inner cantilever of the bay window due to excessive local pressure. At the same time, it can also reduce the span of the supported locking beam 401 to make it more stable. In order to achieve the above purpose, from the perspective of facilitating the installation of multiple groups of limit top support legs 5, an adjustment slide 6 can be provided on the locking beam 401 of the locking support 4 on one side of the fixed end of the operating platform 1. The adjustment slide 6 is arranged along the length direction of the locking beam 401, and several groups of spaced limit top support legs 5 are inserted into the adjustment slide 6;

[0028] like Figure 3 As shown, the limit support leg 5 includes a limit screw 501, a support base 502 and a locking nut 503. The limit screw 501 is inserted into the locking beam 401, and the bottom end thereof is fixedly provided with a support base 502. The support base 502 can effectively increase the contact area between the limit screw 501 and the inner cantilever plate of the bay window, reduce the pressure on the contact surface, and improve the stability of the limit support leg 5. The locking nut 503 is correspondingly sleeved on the limit screws 501 on both sides of the locking beam 401. The limit screw 501 can be switched between the locked and adjustable states by adjusting the upper and lower sets of locking nuts 503, thereby facilitating the adjustment of the support height of the limit screw 501, so that it can better cooperate with the tie end 402 to be clamped and fixed;

[0029] Considering the limited vertical height of the bay window, in order to prevent the height of the protective fence 2 from being too high and affecting the installation of the operating platform 1, the protective fence 2 made of galvanized steel pipe is preferably divided into two sections, the lower section of the protective fence 2 is fixedly arranged on the operating platform 1, and the upper section of the protective fence 2 is detachably fixed to the lower section of the protective fence 2 through the connecting sleeve 3;

[0030] Of course, for safety reasons, the rear ends of the unloading rope 9 and the safety protection rope 10 are respectively fixed to two different pull rings 7 to avoid safety problems.

[0031] The specific installation steps of this utility model are as follows:

[0032] 1. Install the unloading rope 9 of the operating platform 1 in advance: install a set of locking supports 4 with pull rings 7 in advance at the inner cantilever of the upper bay window, and install the unloading rope 9 and the safety rope 10 on the two pull rings 7 corresponding to the locking beam 401, wherein the unloading rope 9 is not fixed at this time, and is held by the operator to cooperate with the subsequent installation of the operating platform 1;

[0033] 2. Installation of the operating platform 1: The staff will place the frame at the working position, lower the unloading rope 9 and the safety rope 10 from the upper layer, fix the bottom end of the unloading rope 9 to the pull ring 7 at the front end of the operating platform 1, and the staff of the outrigger frame will extend the operating platform 1 and adjust it to the required working position. The upper-level operators will cooperate with the outrigger frame staff to gradually release the unloading rope 9, and then fix the frame to the structure, and the anti-tilt tie end block 402 will clamp the inner cantilever plate. The position of the limit top support leg 5 is adjusted by adjusting the slide 6. After adjusting it in place, tighten the locking nuts 503 on both sides at appropriate positions to clamp the inner cantilever plate of the concrete bay window. Then, the upper-level installers will tighten the unloading rope 9 and fix it to the pull ring 7 of the locking beam 401;

[0034] 3. Assembling the protective fence 2: Hang the safety rope 10 on the frame installer, and the installer directly inserts the upper railing into the connecting sleeve 3 on the operating platform 1, and fixes the railing with bolts to ensure that the railing is stable and secure;

[0035] 4. Disassembly sequence: first release the connection between the upper locking support 4 and the unloading rope 9, and then the operator gradually moves the operating platform 1 to the side of the adjacent room. The operator stands on the bay window sill and disassembles the protective fence 2 layer by layer. During this process, the operator standing at the bay window position and the operator on the upper layer must wear a safety rope 10. The safety rope 10 of the upper operator can be directly tied to the pull ring 7 of the unloading rope 9 previously set. The operator on the upper layer pulls the unloading rope 9 and cooperates with the operator on the lower layer to gradually move the operating platform 1 into the room. Then, the operating platform is visually inspected and cleaned to ensure subsequent turnover preparations.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
