Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a temporary attachment device for climbing scaffolding in open areas. Background Technology

[0002] Attached lifting scaffolding, also known as climbing scaffolding, is a new type of scaffolding system that has become increasingly popular in recent years. It is mainly used in high-rise buildings and can ascend or descend along the building. Due to the diversification of building shapes and the increasing complexity of building facades in recent years, climbing scaffolding requires attachment points during ascent or descent. In particular, when climbing scaffolding encounters open areas, the universality of traditional climbing scaffolding is relatively poor.

[0003] Chinese utility model patent CN213297080U discloses a temporary attachment component for a climbing scaffold in an open area. This device includes embedded parts in the structural floor slab, an adjustable attachment section, and a diagonal brace assembly. The lower end of the adjustable attachment section is fixed to the embedded parts with bolts. An inner anchor is hinged to the diagonal brace, and the other end of the diagonal brace is connected to the embedded parts in the floor slab. An attachment device for the climbing scaffold is installed on the outer side, supplemented by lateral reinforcement with steel wire ropes. By adjusting the height of the adjustable attachment section in conjunction with the climbing scaffold's ascent, the problem of no attachment points in open areas is solved, achieving stable lifting of the climbing scaffold.

[0004] However, the patented adjustable attachment section is assembled by stacking two or more standard attachment frame sections. The design of the standard attachment frame section realizes the function of adjusting the height of the temporary attachment component of the climbing frame. However, due to the design of the standard attachment frame section, the standard section needs to be installed repeatedly until the designed adjustable attachment section height is reached, which results in low installation efficiency and affects the construction progress. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a temporary attachment device for scaffolding in open areas, which solves the problem of low installation efficiency in existing technologies where the attachment point height is adjustable.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a temporary attachment device for a climbing scaffold in an open area, comprising a steel column composed of two channel steels arranged opposite each other and a tie plate on each side of the steel column; the channel steel has an opening facing outward, a base welded to the bottom end, an upper limit welded to the top end, and a lower limit welded to the middle; the tie plate has two openings evenly distributed along the central axis; the base of the steel column is fixedly connected to the main structural beam by vertical through-beam bolts, the inner side of the top of the steel column is fixedly connected to anchors, the anchors are fixedly connected to the through-floor bolts by diagonal braces, and the climbing scaffold attachment device is fixedly connected to the outer side of the steel column by the tie plate.

[0007] Furthermore, a fastener is welded to the lower part of the steel column. The fastener further enhances the overall stability of the steel column.

[0008] Furthermore, the channel steel between the upper and lower limits is provided with a groove.

[0009] Furthermore, the tie plate is provided with a protrusion that matches the groove of the channel steel. The groove of the channel steel and the protrusion of the tie plate ensure that the channel steel and the tie plate fit tightly together, preventing relative slippage of the tie plate.

[0010] The beneficial effects of this plan are:

[0011] 1. The steel column has a groove structure between the upper and lower limit positions on the side of the channel steel, which allows the tie plate to be fixed at different height positions by bolts, forming a multi-level adjustment point, which can flexibly adapt to the needs of different climbing stages of the climbing frame.

[0012] 2. The steel columns, made of symmetrical channel steel, can be installed in one go, which improves installation efficiency and speeds up the construction progress. Attached Figure Description
