[0003] The existing Chinese patent CN217518108U discloses a cantilever scaffolding for building construction on September 30, 2022, which includes a cantilever steel beam, fixed convex columns and through holes. Two fixed convex columns are arranged at one end of the cantilever steel beam, and the through holes are arranged on the fixed convex columns. Fixed seats are installed at the other end and below the middle of the cantilever steel beam. Connecting screws are arranged at the four corners above the fixed seats. A pressing plate is arranged above the cantilever steel beam corresponding to the fixed seats, and an anti-slip convex block is fixed on the cantilever steel beam on one side corresponding to the position of the pressing plate.

[0004] However, when the above-mentioned cantilever scaffolding for building construction is in use, the construction is carried out through the framework erected on the cantilever steel beam.

[0031] Refer to Figures 1 - 5 , a cantilevered construction scaffold includes an upper beam plate 1, a lower beam plate 2 and a cantilever steel beam 4. The upper beam plate 1 is horizontally above the lower beam plate 2. The upper end surface of the lower beam plate 2 is provided with the cantilever steel beam 4. The lower beam plate 2 and the cantilever steel beam 4 are installed and connected through the steel frame fixing mechanism 3, so that the cantilever steel beam 4 will not fall during cantilever. A frame body positioning rod 41 is fixedly connected above the outer end of the cantilever steel beam 4. The frame body positioning rod 41 is provided with a scaffold erection body 7 around it. The scaffold erection body 7 can be correspondingly installed and placed through the frame body positioning rod 41. An inclination detection mechanism 5 is installed on the outer side of the scaffold erection body 7 on the cantilever steel beam 4. The inclination detection mechanism 5 can be in contact with the outer side of the scaffold erection body 7 to detect the inclination. A pulling steel rope 6 is installed between the cantilever steel beam 4 and the upper beam plate 1 for pulling and fixing. The inclination detection mechanism 5 is electrically connected to an external warning device through a connecting wire. When the inclination detection mechanism 5 detects an inclined state, it can control the external warning device to give a prompt, thus ensuring the safety of personnel during use;

[0032] The tilt detection mechanism 5 includes a resisting spring 51, a hollow casing 52, a touch switch 53, a movable inner block 54 and an outer rubber block 55. The hollow casing 52 is fixedly connected to the cantilevered steel beam 4, so that the hollow casing 52 can be installed and placed accordingly. The inner right end of the hollow casing 52 is fixedly connected to the touch switch 53. Both sides of the touch switch 53 are located on the hollow casing 52 and are fixedly connected to the resisting spring 51. The outer end of the resisting spring 51 is located on the hollow casing 52 and is fixedly connected to the movable inner block 54. The movable inner block 54 The outer end of the scaffold is adhered with an outer rubber block 55, which contacts the outer surface of the scaffold erection body 7. When the scaffold erection body 7 is tilted, the outer rubber block 55 moves inward, and the outer rubber block 55 drives the movable inner block 54 to move inward in the hollow casing 52, so that the movable inner block 54 deforms the contact spring 51. When the movable inner block 54 touches the touch switch 53, the internal electrical circuit of the touch switch 53 is opened, which can control the external warning device to issue a prompt, thereby ensuring the safety of personnel when using it.

[0033] Reference Figures 1 - 3 In a preferred embodiment, the scaffold erection body 7 includes a transverse steel pipe 71, a longitudinal steel pipe 72 and a vertical steel pipe 73. The four vertical steel pipes 73 are transversely fixed with the transverse steel pipe 71 through a cross fitting, and the four vertical steel pipes 73 are longitudinally fixed with the longitudinal steel pipe 72 through a cross fitting, so that the transverse steel pipe 71, the longitudinal steel pipe 72 and the vertical steel pipe 73 can be erected to form a frame for use, and the vertical steel pipe 73 is threadedly rotatably installed and connected to the frame positioning rod 41, so that it can be installed and fixed accordingly;

[0034] The vertical steel pipe 73 is threadedly rotatably mounted on the frame positioning rod 41, making it easy to install and fix.

[0035] Reference Figures 1 - 4 In a preferred embodiment, the steel frame fixing mechanism 3 includes a mounting base plate 31, an upper screw rod 32, a locking nut 33 and a double-hole panel 34. The mounting base plate 31 is fixedly connected to the lower beam plate 2 so that it can be stably placed. Upper screw rods 32 are fixed on both sides of the upper end of the mounting base plate 31, so that the cantilevered steel beam 4 can be located between the two upper screw rods 32. Double-hole panels 34 are installed around the two upper screw rods 32, so that the double-hole panel 34 can be located above the cantilevered steel beam 4. A locking nut 33 is threadedly installed on the upper screw rod 32 above the double-hole panel 34, so that the locking nut 33 can contact the double-hole panel 34 when it is rotated downward. In this way, the double-hole panel 34 is located above the cantilevered steel beam 4 to play a blocking and fixing role, thereby preventing the cantilevered steel beam 4 from falling when it is cantilevered.

[0036] Reference Figure 1 and Figure 2, in a preferred embodiment, the pulling steel rope 6 includes an upper fixed end 61, a lower fixed end 62 and a steel rope body 63. The upper end of the steel rope body 63 is fixedly connected to the upper fixed end 61, and the lower end of the steel rope body 63 is fixedly connected to the lower fixed end 62. The lower fixed end 62 is connected to the cantilever steel beam 4, and the upper fixed end 61 is installed and connected to the upper beam plate 1. Thus, the steel rope body 63 forms a pulling hypotenuse between the cantilever steel beam 4 and the upper beam plate 1, so that it can be stably placed and used.

[0037] Refer to Figures 1 - 4 , in a preferred embodiment, the number of the inclination detection mechanisms 5 corresponds to that of the cantilever steel beams 4. A total of two inclination detection mechanisms 5 are installed, so that they can be correspondingly installed and placed for detection.

[0038] Refer to Figures 1 - 4 , in a preferred embodiment, two steel frame fixing mechanisms 3 are sleeved and installed at the left end of each cantilever steel beam 4, so that the cantilever steel beam 4 is more stable when cantilevered.

[0039] Working principle: During use, the lower beam plate 2 and the cantilever steel beam 4 are installed and connected through the steel frame fixing mechanism 3, so that the cantilever steel beam 4 will not fall when cantilevered. The cantilever steel beam 4 enables the scaffolding erection body 7 to be correspondingly installed and placed through the frame positioning rod 41 above the outer end. A pulling steel rope 6 is installed between the cantilever steel beam 4 and the upper beam plate 1, so that it can be pulled and fixed for use. The inclination detection mechanism 5 can abut against the outside of the scaffolding erection body 7 to detect the inclination degree. When the inclination detection mechanism 5 detects an inclined state, it can control an external warning device to issue a prompt, thus ensuring the safety of personnel during use.
