Description

Technical Field

[0001] This utility model relates to the field of construction technology for ultra-high-rise buildings, specifically to an all-steel attached lifting scaffolding structure for ultra-high-rise building attachment and conversion construction. Background Technology

[0002] Attached lifting scaffolding, as an effective means of protecting the exterior facades during structural construction, has been widely used in the building engineering field. While it fully meets protection requirements in ordinary residential projects, it has certain limitations in high-rise buildings. One significant challenge lies in the construction of refuge floors. Because refuge floors in high-rise buildings serve as transitional floors for building equipment and functional areas, their height is considerably higher than standard floors. However, the initial design of the climbing scaffolding must ensure its height is appropriate for the building's standard floors. This makes the protection of refuge floors a major challenge.

[0003] Existing attachment methods involve using additional concrete frame beams or steel beams for support. Installation and dismantling often involve working near edges, especially during the later stages of dismantling, which requires significant investment in safety measures. The dismantling process generates a lot of dust and noise, posing a high risk. The dismantled concrete columns are mostly broken pieces, requiring a combination of bulldozers and manual labor to remove as construction waste. This process is labor-intensive, has low material utilization, and a significant environmental impact, resulting in low economic and environmental benefits. Utility Model Content

[0015] In a preferred embodiment, the steel column stiffening ribs are also included. The steel column stiffening ribs are rectangular chamfered steel plates, and one steel column stiffening rib is provided every 800mm along the height direction of the steel column.

[0016] In a preferred embodiment, the ear plate is a double ear plate type, and a first ear plate for connecting the horizontal connecting rod and a second ear plate for connecting the vertical diagonal tie rod are provided on the steel column located below the attachment end plate, and the lower end of the vertical diagonal tie rod is fixed to the anchor plate reserved on the structural plate surface.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model provides a construction structure for situations where the top support of an attached lifting scaffold cannot be attached when it is raised to a non-standard floor (refuge floor, roof pergola beam, or other special structures). This utility model provides an attachment point for the attached lifting scaffold by fixing steel columns to the base and attachment end plates, and connecting the attachment end plates to the wall-mounted support bolts. This allows the scaffold to be raised, ensuring the overall protective height of the working surface. Simultaneously, the connection between the steel columns and the wall-mounted support reduces the cantilever height of the scaffold. The free end height of the all-steel attached lifting scaffold in this project is less than 6 meters (and less than 2 / 5 of the total scaffold height), greatly improving the safety of the scaffold itself and the workers, meeting the requirements of safe and civilized construction.

Two column foot stiffening ribs 6 are provided on each of the four sides of the column foot of the steel column 2, and the bottom of the column foot stiffening ribs 6 is welded to the top of the base plate 11. The column foot stiffening ribs 6 are triangular steel plates.

[0030] Furthermore, the lower part of the vertical section of the steel plate corner plate 12 is provided with two third threaded holes. The vertical section of the steel plate corner plate 12 is fixedly connected to the structural anti-sill 10 through the through bolt 112, and two stiffening ribs are provided on the outer side of the vertical section of the steel plate corner plate 12.

[0031] Furthermore, the attachment end plate 3 is a rectangular steel plate. Based on the location of the attached lifting scaffold, six sets of threaded holes are symmetrically opened on the rectangular steel plate. The threaded hole in the middle is used for the connection of the wall-mounted support 100, and the threaded holes on both sides are the attachment points for the hanging seats. Since the attachment end plate 3 is set on both sides, 40mm steel pipes are used to connect the threaded holes to protect the screws from rust caused by rainwater erosion. The steel column 2 is an I-beam, and multiple connecting plates 7 and stiffening ribs 8 are set at the location of the attachment end plate 3 to enhance the torsional resistance and rigidity of the attachment end plate and ensure the load-bearing requirements of the attachment point of the attached lifting scaffold. The connecting plate 7 is a rectangular steel plate, with two attachment end plates 3 connected to each end of the connecting plate 7, serving as a horizontal support to reduce the cantilever length of the attachment end plate. The stiffening rib 8 is a triangular steel plate, supporting the bottom of the connecting plate 7 and welded laterally to the steel column 2 on both sides, enhancing the rigidity and stability of the attachment end plate.

[0032] Furthermore, it also includes steel column stiffening ribs 9, which are rectangular chamfered steel plates, and one steel column stiffening rib 9 is set every 800mm along the height direction of the steel column.

[0033] Furthermore, the ear plate 5 is a double-ear plate type, and a first ear plate for connecting the horizontal connecting rod 51 and a second ear plate for connecting the vertical diagonal tie rod 52 are provided on the steel column 2 located below the attachment end plate 3. The first ear plate is welded and fixed on both sides of the steel column 2. The horizontal connecting rod 51 is fixed between the two columns by inserting a pin into the ear plate 5. The upper end of the vertical diagonal tie rod is fixed to the second ear plate, and the lower end of the vertical diagonal tie rod is fixed to the anchor plate reserved on the structural plate surface.

[0034] Example 2

[0035] The specific installation and construction methods of this utility model are described below:

[0036] In this embodiment, the steel column 2 is available in 3-meter and 4.5-meter specifications. The column body is made of 30# I-beams. 8mm thick stiffening ribs 9 are installed at 0.8-meter intervals along the height of the steel column 2. The steel column 2 is fixed to the structural retaining wall 10 via a base plate 11. The base plate 11 of the steel column 2 is made of 12mm thick rectangular steel plate. 35mm diameter threaded holes are pre-drilled at the four corners of the base plate in the factory. To accommodate the column base installation with the on-site concrete flange, inverted L-shaped steel plate corner plates 12 are installed. The base plate 11 is fixedly connected to the horizontal part of the steel plate corner plates 12 via a first threaded rod. The vertical parts of the two steel plate corner plates 12 are fixedly connected to the structural retaining wall 10 via through-bolts. Two 12mm thick, 0.73m long, and 0.38m wide attachment end plates 3 are welded to the top of the column. Six holes are opened on the attachment end plates, and connecting plates 7 and stiffening ribs are added to maintain sufficient torsional resistance and rigidity.

[0037] After the entire component is hoisted to the corresponding position on the attached lifting scaffold using a tower crane, connecting rods 51 are installed between the steel columns to form a whole. After the horizontal connecting rods are connected, vertical tie rods 52 are installed on each steel column, perpendicular to the outer contour. The lower ends of the vertical tie rods are fixed to the anchor plates reserved on the structural slab to enhance the lateral displacement resistance of the steel columns in the Y direction.

[0038] Specifically, it includes the following steps:

[0039] (1) Level the top surface of the concrete flange to ensure that the base plate of the steel column base is fully in contact with the flange without arching or depression.

[0040] (2) After the steel column is installed in place, the column body is reinforced by diagonal bracing. The diagonal bracing adopts adjustable vertical tie rod 52. The top of the vertical tie rod is fixed to the second ear plate and fixed with M28 screw rod. The bottom of the vertical tie rod 52 is connected to the embedded plate of the floor slab.

[0041] (3) After the vertical tie rod is fixed, the connecting rod 51 is immediately set. The horizontal connecting rod 51 is an adjustable tie rod, and both ends are connected to the first ear plate on the side of the steel column 2 and fixed.

[0042] (4) After the entire tie system is installed, the wall supports of the all-steel attached lifting scaffold can be installed. At this time, it should be noted that three sets of wall supports are needed in the formal use state of this project. Before lifting, one set of supports should be reserved for the top floor pre-installation to ensure that the three sets of supports are restored immediately after the all-steel attached lifting scaffold is lifted.
