Description

Technical Field

[0001] The present invention relates to the field of suspended scaffolds, and particularly to a construction method for a unitized high-altitude rapid-assembly suspended scaffold. Background Art

[0002] In recent years, aerial structures such as skywalks between buildings have been widely used because they do not occupy ground space. Facing the high-operation problems brought by the construction of the decorative finishes at the bottom of aerial structures and the subsequent maintenance, at present, most methods such as erecting full-floor scaffolds and vertical aerial work platforms are adopted as the climbing measures for operators. However, the high-altitude bulk-assembly method generally used for suspended scaffolds has, on the one hand, high investment in measures and long construction periods, and on the other hand, has strict requirements for the bearing capacity of the lower ground corresponding to the aerial structure, and the risks of high-altitude falling objects during the erection and demolition processes are huge. Finally, after the building is completed, the ground under the aerial structure is often greened and generally paved. If constructed in these ways, the subsequent maintenance of the bottom of the aerial structure will be very difficult. Summary of the Invention

[0003] To solve the technical problems existing in the prior art, the present invention provides a construction method for a unitized high-altitude rapid-assembly suspended scaffold.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A construction method for a unitized high-altitude rapid-assembly suspended scaffold includes the following steps:

[0006] Step 1, assembling a standard unit with a fence and a standard unit without a fence;

[0007] Step 2, lifting the standard unit with a fence to a specified high-altitude position;

[0008] Step 3, lifting multiple standard units without a fence to the corresponding positions on the sides of the standard unit with a fence in a "pin" shape;

[0009] Step 4, turning down the flip-up grille on the side of the standard unit with a fence and connecting it to the hook on the bottom side of the standard unit without a fence;

[0010] Step 5, repeating the above steps to build the suspended scaffold platform, and finally setting detachable lateral guardrails around the platform.

[0011] As a preferred technical solution, the fenceless standard unit includes a bottom fixed rod, a bottom fixed grid, a hanging rod and an adjustable spherical joint node. In step one, the steps of assembling the fenceless standard unit include enclosing four bottom fixed rods into a rectangular frame; installing another bottom fixed rod on a diagonal line of the rectangular frame; installing the bottom fixed grid in the rectangular frame; setting the adjustable spherical joint nodes at the four corners of the rectangular frame; connecting the ends of the four bottom fixed rods of the rectangular frame with adjustable spherical joint nodes; setting the hanging rod vertically, and installing the bottom end of the hanging rod on each adjustable spherical joint node.

[0012] As a preferred technical solution, the adjustable spherical joint node includes a spherical inner joint and a spherical outer shell, the end of the bottom fixed rod is fixedly connected to the spherical outer shell, the spherical inner joint is arranged in the spherical outer shell, and the bottom end of the suspension rod is fixed on the spherical inner joint.

[0013] As a preferred technical solution, the cross-sectional shape of the spherical shell is a major arc, and the center of the spherical inner joint is located inside the spherical shell.

[0014] As a preferred technical solution, the fenced standard unit includes all the components and structures of the unfenced standard unit, and also includes a flipping mechanism and a side flippable grille. The side flippable grille is axially rotatably connected to the bottom fixed rod through the flipping mechanism.

[0015] As a preferred technical solution, a hook matching the side flip grille is provided on the bottom fixed rod of the fenceless standard unit, and the side flip grille is connected to the bottom fixed rod of the fenceless standard unit through the hook after being flipped.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention prefabricates standard unit modules and then hoists them, converts the lateral protection of the unit modules into bottom protection at high altitude, and does not require assembly of loose parts during the high altitude assembly process, which is not likely to cause objects to fall from high altitudes, and can quickly form an overall high altitude suspended scaffold. The present invention can efficiently, safely, quickly and economically realize the installation and maintenance of the bottom facing of aerial structures such as corridors under all working conditions.

[0025] The technical solution of the present invention will be further described below in conjunction with specific embodiments:

[0026] A construction method for a unit type high-altitude rapid assembly suspension scaffold includes the following steps:

[0027] Step 1, as shown in Figure 1 and Figure 2 , assemble the fence standard unit and the non-fence standard unit;

[0028] Step 2, lift the fence standard unit to the designated high-altitude position;

[0029] Step 3, as shown in Figure 4 , lift multiple non-fence standard units to the corresponding positions on the sides of the fence standard unit in a "pin" shape;

[0030] Step 4, as shown in Figure 5 , turn down the side flippable grille 6 of the fence standard unit and connect it to the hook on the bottom side of the non-fence standard unit;

[0031] Step 5, as shown in Figure 6 , repeat the above steps to build the suspension scaffold platform, and finally set up detachable side guardrail plates around the platform.

[0032] The fenceless standard unit includes a bottom fixed rod 1, a bottom fixed grid 2, a hanging rod 3 and an adjustable spherical joint node 4. The bottom fixed rod 1 encloses a rectangular frame. A longer bottom fixed rod 1 is also installed on a diagonal line of the rectangular frame to improve the stability of the rectangular frame. The bottom fixed grid 2 is installed in the rectangular frame. The adjustable spherical joint node 4 is located at the four corners of the rectangular frame. The ends of the bottom fixed rod 1 are connected through the adjustable spherical joint nodes 4. The hanging rod 3 is vertically arranged and the bottom end is installed on each adjustable spherical joint node 4.

[0033] like Figure 3 As shown, the adjustable spherical joint node 4 includes a spherical inner joint 41 and a spherical outer shell 42, the end of the bottom fixed rod 1 is fixedly connected to the spherical outer shell 42, the spherical inner joint 41 is arranged in the spherical outer shell 42, and the bottom end of the suspension rod 3 is fixed on the spherical inner joint 41, thereby improving the adjustable spherical joint node connecting the suspension rod 3 and the bottom fixed rod 1.

[0034] The cross-sectional shape of the spherical outer shell 42 is a major arc, and the center of the spherical inner joint 41 is located inside the spherical outer shell 42 to prevent the spherical inner joint 41 from detaching from the spherical outer shell 42 .

[0035] The fenced standard unit includes all the components and structures of the unfenced standard unit, and also includes a flipping mechanism 5 and a side flippable grille 6. The assembly steps of the fenced standard unit are as follows: on the basis of the unfenced standard unit, the flipping mechanism 5 is installed on the four sides of the bottom rectangular frame, i.e., the four bottom fixed rods 1, and the side flippable grille 6 is connected to the flipping mechanism 5. Through the flipping mechanism 5, the side flippable grille 6 can be axially rotated around the bottom fixed rod 1.

[0036] The bottom fixing rod 1 of the standard unit without fence is provided with a hook matching with the side flip grille 6, and the side flip grille 6 is connected to the bottom fixing rod 1 of the standard unit without fence through the hook after flipping. In actual operation, the hook can also be replaced with a buckle, so that the side flip grille 6 of the standard unit with fence is connected to the bottom fixing rod 1 of the standard unit without fence in a buckle-type manner.

[0037] This embodiment is only a further explanation of the invention rather than a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the invention, they are protected by the patent law.
