At the realm of building construction, lower foundation ditch passage generally adopts simple and easy the setting up of steel pipe can utilize on-the-spot material, draws materials conveniently, but in Super Deep Foundation Pit Construction, pattern foundation pit supporting structure and the Main Underground body structure construction period longer, adopt steel pipe to set up and there is inconvenience.
In the pit earthwork excavation stage, earthwork face declines with excavation progress, and steel tube pathway cannot be set up in scene;
Adopt steel pipe to set up Channel Engineering amount large, set up program loaded down with trivial details;
Passage set up by steel pipe, and floor space is large, is unfavorable for foundation ditch Ground arrangement;
Steel pipe is set up passage peace and is torn complexity open, length consuming time.
Utility model content
The purpose of this utility model is, provides that a kind of safe and reliable, construction and installation are quick, location is simple, good looking appearance is generous, rigidity and globality is good, the lower foundation ditch steel stair passage that can reuse.
Steel stair is mainly reliably connected with inner support beam by the utility model, Appropriate application foundation ditch inner space, reduces lower foundation ditch plank road to the impact of foundation ditch layout.
This lower foundation ditch steel stair passage is made up of the section of marking time, half space, platform and brace summer, the section of marking time comprises girder (1), setscrew (2), steel junction plate (3), supports angle steel (4), foot pedal (5), railing (6), half space by: railing (6), landing slab (7), platform longeron (8), platform beams (9) form, platform by: steel junction plate (3), steel post (10) form.The section of marking time upper end is connected with brace summer, and the section of marking time lower end and platform longeron (8) are welded to connect; Halfpace plate (7) is supported on platform longeron (8), platform beams (9) by welding, and the welding of platform longeron (8), platform beams (9) is supported on steel post (10); Steel post (10) top is connected with platform longeron (8), platform beams (9) by steel junction plate (3), and steel post (10) bottom is connected with brace summer.Described girder (1) lower end is by being welded to connect to platform longeron (8); Foot pedal (5) is by being welded to connect on girder (1); Railing (6) is by being welded to connect on girder (1).
Compared with the plank road that the utility model and steel pipe are set up, have the following advantages:
1) steel structure stairway is steel structures coating, and whole component can be recycled.
2) steel structure stairway is clearly stressed, and stair bench is main bearing member, and load is finally passed to brace summer, and stress point is reliable.
3) steel structure stairway bench step plate is provided with support angle steel in bottom, improves globality and the fastness of whole stair.
4) steel stair is supported on brace summer, and overall appearance is generous, simple economy, is applicable to the base pit engineering adopting inner support system.
