It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

The embodiment of the present invention provides a quick-installation aluminum alloy scaffold. As shown in FIG. 30. A plurality of supporting devices 40 for enhancing the stability of the scaffold, a plurality of inclined ladders 50, a plurality of horizontally arranged pedals 60, a working platform 70 and a protective device for preventing personnel from falling. As shown in FIG. 1 and FIG. 2 , each door frame 10 includes a plurality of brackets 11 , and each bracket 11 is detachably connected in the vertical direction. Each support 11 includes two vertically arranged vertical rods 111 and a plurality of horizontally arranged connecting rods 112 . Two poles 111 are arranged side by side. Both ends of each connecting rod 112 are respectively fixedly connected with two upright rods 111 .

Two vertical rods 111 and a plurality of connecting rods 112 are assembled into a bracket 11 , and the plurality of brackets 11 are stacked in sequence in the vertical direction to be assembled into a door frame 10 . Specifically, two ends of each connecting rod 112 are respectively provided with a collar, and the collar is welded to the connecting rod 112 and sleeved on the vertical rod 111 . The process of internal expansion and external pressure is adopted during processing, and the destructive pull-off force of the joint reaches 4100 kg to 4400 kg (the allowable pull-off force of ordinary scaffolding is 2100 kg).

As shown in FIG. 3 and FIG. 4 , each cross bar 20 is perpendicular to the connecting rod 112 . Each cross bar 20 is located between two door frames 10 and has first hooks 21 at both ends. Each first hook 21 is engaged with a corresponding upright pole 111 . Each slanting rod 30 is located between two door frames 10 and has a second hook 31 at both ends. Each second hook 31 is engaged with the corresponding connecting rod 112 . Each oblique rod 30 forms a certain angle with the horizontal plane, and two adjacent oblique rods 30 are arranged in a figure-eight shape.

Each cross bar 20 connects the two door frames 10 as a whole. Both ends of the cross bar 20 are respectively provided with first hooks 21 . When assembling, the two first hooks 21 are respectively snapped onto the corresponding upright bars 111 . Specifically, the first hook 21 is wedge-shaped, wide on the outside and narrow on the inside, which is convenient for assembly and secure in connection.

The diagonal rod 30 improves the connection strength between the two door frames 10 . Two ends of the oblique rod 30 are respectively provided with second hooks 31 , and when assembled, the two second hooks 31 are respectively snapped onto the corresponding connecting rods 112 . Specifically, the second hook 31 is wedge-shaped, wide on the outside and narrow on the inside, which is convenient for assembly and secure in connection. In the vertical direction, each oblique rod 30 is accumulated sequentially, and two adjacent oblique rods 30 are arranged in a figure-eight shape, which has a reasonable structure, saves materials, and has high connection strength.

As shown in FIG. 1 and FIG. 7 , each support device 40 corresponds to each vertical pole 111 one by one. The first end of each supporting device 40 is detachably connected to the corresponding upright pole 111 , and the second end is used to be fixed on the ground. Each supporting device is evenly distributed around the portal frame 10 for enhancing the overall stability of the scaffolding. When the height of the scaffold is greater than 3 meters, construction workers climb onto the working platform, and the overall structure is in a state of being heavy at the top and light at the bottom, which poses a safety risk. Therefore, it is necessary to install a support device 40 to increase the area of the bottom of the entire structure and disperse the pressure. Play the role of counterweight. The support device 40 is detachably connected to the pole 111 for easy assembly or disassembly.

As shown in FIG. 5 and FIG. 6 , each inclined ladder 50 is located between two door frames 10 , and a plurality of third hooks 51 are provided at the ends. Each third hook 51 is engaged with the corresponding connecting rod 112 . Each inclined ladder 50 forms a certain angle with the horizontal plane. Inclined ladder 50 is used for personnel to climb. Since the inclined ladder 50 is located between the two door frames 10 and is arranged obliquely, the personnel are always located inside the overall structure during the climbing process, and the force on the door frames 10 is even and the stability is high. In the prior art, people mostly climb upwards through the portal frame 10, and the force on the whole structure is uneven. The portal frame 10 on one side bears a large force, while the portal frame 10 on the other side bears a small force, so it is easy to tilt or even fall sideways. situation, the security risk is high. Specifically, the angle between the inclined ladder 50 and the horizontal plane is 45 degrees.

Each step 60 is located between two inclined ladders 50 in the vertical direction, and a plurality of fourth hooks 61 are arranged at the end. Each fourth hook 61 is engaged with the corresponding connecting rod 112 . The pedal 60 is used for personnel to temporarily stay and build the superstructure. When the overall height of the scaffold is greater than 3 meters, the construction shall be carried out in stages from bottom to top. After the bottom component is built, the construction personnel climbs onto the pedal 60 through the inclined ladder 50, and then can stand on the pedal 60 to build the component of the upper layer. Specifically, the width of the pedal 60 is smaller than the overall width of the scaffold.

As shown in FIG. 1 and FIG. 11 , the working platform 70 is located above each inclined ladder 50 in the vertical direction. The working platform 70 includes a platform board 71 and a door board 72 arranged horizontally. The end of the platform board 71 is provided with a plurality of fifth hooks, and each of the fifth hooks is engaged with a corresponding connecting rod 112 . Through holes are formed on the platform board 71 . The door panel 72 is located at the through hole and is hinged with the platform panel 71 .

The working platform 70 is close to the construction site, and construction workers climb onto the working platform 70 to work. The platform board 71 is provided with a through hole, and when the personnel approach the platform board 71 by the inclined ladder 50, the door panel 72 is opened, and enters on the platform board 71 from the through hole. The protective device is arranged around the door frame 10 to prevent personnel from falling and being injured.

Since construction personnel need to stand on the platform board 71 to carry out operations, and will carry tools and work supplies with them, the larger the area of the platform board 71, the more convenient the construction personnel's work. However, the larger the area of the platform board 71, the more difficult it is to erect it. When the width is close to the overall width of the scaffold, construction personnel stand on the lower floor pedal 60 and cannot climb onto the platform board 71 after the platform board 71 is erected. Therefore, in this embodiment, a through hole is opened on the platform plate 71, and the door plate 72 is installed at the through hole. After the platform panel 71 is set up, the door panel 72 is opened, and personnel enter the platform panel 71 from the through hole, and then the door panel 72 is closed to work safely on the platform panel 71.
