It states there are four gear supports at least and is arranged at intervals on the main branch back side of ladder.
Further, the hook is L-shaped, and L-type hooking slits are downward, and L-type long side one end and the main branch top rear face of ladder are welded
Meet fixation, L-type short side and the main Zhi Pinghang of ladder.
Further, L-type long side top surface and the main branch either flush of ladder.
Further, gear support is triangular structure, and triangle a line is welded and fixed with the main branch of ladder.
Further, the main Zhi Caiyong 50mm*4mm angle steel of ladder or diameter 12MM round steel.
Further, the spacing of two main branch of ladder is 500mm.
Further, it marks time using diameter 12MM round steel.
Further, the adjacent spacing marked time is 30MM.
Further, it marks time and is fixed between the main branch of ladder using overlap welding, weld bead height 6mm.
Further, the main Zhi Gaodu of ladder is 600mm-900mm.
The beneficial effects of the utility model are embodied in:
1, the utility model cooperates steel column lifting construction steel ladder, and structure is simple, and rationally, material is extensive, price for design
It is cheap, it is easy to make quick, it is no longer necessary to ladder is welded on steel column, is directly sliced off with burning torch after being finished, it will not be to steel column
Component damages.The main branch back side of ladder is provided with the gap being used to support between ladder and steel column, and ladder is avoided to be close to steel column
Gear support, is climbed convenient for construction personnel.Practicability with higher.
2, the utility model cooperates steel column lifting construction steel ladder, and steel ladder stable structure, worker is safe and convenient to use,
And it can be used in turn, reduce construction cost, not will cause the waste of resource.
3, the utility model cooperates steel column lifting construction steel ladder, in order to cooperate steel column to lift, to the maximum extent to apply
Worker person provides the construction channel of handy and safe, provides worker close to construction location, well to worker as far as possible
Construction environment and space.The precision and positioning for greatly improving Steel Structure Installation, ensure that construction quality.
The utility model cooperation steel column lifting construction can be widely applied in steel structure column construction operation with steel ladder.
Other features and advantages of the utility model will illustrate in the following description, and partly from specification
It becomes apparent, or is understood and implementing the utility model.The main purpose and further advantage of the utility model can lead to
Specifically noted scheme in specification, claims is crossed to be achieved and obtained.
Detailed description of the invention
The utility model is described in more detail with reference to the accompanying drawing.
Fig. 1 is the utility model main view.
Fig. 2 is the utility model side view.
Appended drawing reference: the main branch of 1- ladder, 2-mark time, 3-gear supports, 4-hooks.
Specific embodiment
In order to cooperate steel column to lift, the construction channel of handy and safe is provided for construction personnel to the maximum extent, this is practical new
Type provides cooperation steel column lifting construction steel ladder, and the main view of ladder marks time 2 as shown in Figure 1, specifically include the main branch 1 of ladder,
Gear support 3 and hook 4,2 parallel intervals of marking time are arranged between the main branch 1 of two ladders；On the hook 4 and the main branch 1 of ladder
The portion back side is welded and fixed.There are four the gear supports 3 at least and is arranged at intervals on main 1 back side of branch of ladder, and gear support 3 is triangle knot
Structure, triangle a line are welded and fixed with the main branch 1 of ladder, and gear support 3 is mainly used for supporting the gap between ladder and steel column, avoid climbing
Ladder is close to steel column, is not easy to construction personnel's climbing.
Wherein, the hook 4 is L-shaped, and Open Side Down for L-type hook 4, and L-type long side one end and main 1 top rear face of branch of ladder are welded
Fixation is connect, L-type short side is parallel with the main branch 1 of ladder.It L-type long side top surface can be with main 1 either flush of branch of ladder.
As shown in Fig. 2, the main branch 1 of ladder uses 50mm*4mm angle steel or diameter 12MM round steel.2 are marked time using diameter 12MM circle
Steel.The spacing of the main branch 1 of two ladders is 500mm；Main 1 height of branch of ladder is 600mm-900mm.Adjacent 2 spacing of marking time is
30MM。
Cooperate steel column lifting construction as follows with steel ladder Force Calculation:
