现有的吊桥折叠式上塔式起重机通道,往往一端
固定在楼层上,另一端固定在塔式起重机标准节上,
随着施工的进程,楼层不断增高,塔式起重机不断升
高,吊桥折叠式上塔式起重机通道距离塔式起重机驾
驶室距离不断升高,此时需要拆掉吊桥折叠式上塔式
起重机通道,在更高楼层重新安装吊桥折叠式上塔式
起重机通道,费时费力,且存在安全隐患。
为此,提出一种吊桥折叠式上塔式起重机通道与
爬架同步提升施工技术。

提升技术工艺原理
吊桥折叠式上塔式起重机通道与爬架同步提升
技术首先通过40 mm×60 mm ×2 mm 的方管焊接形
成通道整体受力框架,然后在通道整体受力框架上
焊接冲孔防护网片,受力框架两侧纵向方管上焊接
40 mm× 60 mm×2 mm及20 mm× 20 mm×2.5 mm的
方管防护栏杆。再同样利用40 mm ×40 mm ×2.5 mm

THE APPLICATION OF SYNCHRONOUS LIFTING TECHNOLOGY FOR THE CHANNEL
AND CLIMBING FRAME OF THE FOLDING TOWER CRANE WITH
SUSPENSION BRIDGE IN THE CONSTRUCTION SITE

[Abstract ] The synchronous lifting technology of folding tower crane passage and climbing frame is suitable
for the high-rise lifting bridge with all-steel attached lifting scaffolding (climbing frame) and super high-rise building
and tower crane. First, the overall force frame of the channel is formed through the square pipe welding, and the
protective railing is formed on both sides of the frame. Then, the punching protective mesh is welded on the overall
stressed frame to form the folding tower crane channel of the crane bridge. After the passage of the folding tower
crane of the overall fixed suspension bridge is lifted to the position of the fourth step of the climbing frame, the tail
of the channel is connected with the climbing pole keel. In the middle and front of the channel are welded with the
round steel lifting ring. One end of the wire rope is connected with the round steel lifting ring of the channel, and the
other end of the wire rope is connected with the guide rod of the climbing rail. After the first floor is completed, the
tower crane driver will withdraw the turning plate at the front end of the channel and lock the protective door near
the climbing frame. The whole steel is attached to the lifting scaffold to drive the overall fixed suspension bridge to
upgrade the folding tower crane channel synchronously.
