Description

The bridgeing rail type attached lift scaffold

The utility model belongs to the highrise building external scaffolding, especially a kind of bridgeing rail type attached lift scaffold.

In high-building construction, the polytype hoisting scaffold is arranged, as integral hoisting scaffold, guide tracked from climbing scaffold, security insurance integral hoisting scaffold, mutual climbing type scaffold, the scaffold of these types, though satisfied construction requirement to a certain extent, but the some shortcomings part is also arranged, as unreasonable structure, troublesome poeration, work efficiency is low, it is big to expend plant capacity, and safeties are safe inadequately, influences construction operation safety.

The purpose of this utility model is: provide a kind of rational in infrastructure, cost is low, the work efficiency height, and processing ease, safe and efficient, anti-drop function is good, can bear the hoisting scaffold of big working load, for low-consumption high-efficiency provides safeguard.

Scheme of the present utility model is: the built-in fitting 10 of outrigger 5 one ends and building is fixing, and its middle part is installed outrigger and supported 2, and outrigger pull bar 4 supports 2 tops and building built-in fitting 10 tractives from outrigger 5 outer ends through outrigger; Lock rod 21, the excellent spring 16 of lock, suspension ring 23, suspension ring spring 22 with automatic anti-drop function also is installed in outrigger 5 outer ends, anti-faller 8 fuses by a plurality of points and scaffold 13, anti-faller 8 also passes guiding crossbeam 7, the gathering sill of outrigger 5 and the guide ring 12 of guide pipe outer end, in the scaffold upper floor steel pipe strengthening frame 1 is installed, guide pipe guide ring 12 is installed on steel pipe strengthening frame 1.Advantage of the present utility model:

1. supporting member---the installation of outrigger is not subjected to the restriction of next level structure, can finish with first floor.

2. the improvement stage can promote the height of two floors at every turn, satisfies the requirement of two floors construction,

3. multiple fall arrest, anti-flare device are arranged, scaffold is promoted steadily, quick, safety.

4. processing ease, cost is low, and is good in economic efficiency.Below in conjunction with accompanying drawing, the utility model is described in detail.
