Reserving hole contraposition, and installed height mark control is inaccurate, unbalance stress is easy to main structure and collides cause to damage in hoisting process
Bad, position inaccurate, this causes very big inconvenience to construction, and installation effectiveness is not high.
Summary of the invention
In view of this, the utility model is directed to a kind of assembled staircase structure, to solve the construction of assembled stair not
Convenient problem.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
The ladder between upper terraced beam and descending stair beam is arranged in including upper terraced beam, descending stair beam, connection in a kind of assembled staircase structure
Section plate；
Pre-buried straight screw sleeve in the upper terraced beam, the straight screw sleeve connect straight thread reinforced bar, and the upper terraced beam is logical
Cross straight thread reinforced bar connection waist slab；The waist slab is equipped with the first cavity, for accommodating straight thread reinforced bar and grouting material,
There are mouth is blocked above first cavity, the junction of the straight thread reinforced bar and the first cavity is additionally provided with cement mortar screeding
Layer；
The straight screw sleeve bottom is C grade bolt, and anchor head is arranged at C grade bolt bottom；
The upper terraced beam, waist slab with and the second cavity for surrounding of straight thread reinforced bar in filled with polyphenyl obturator, it is described
It is additionally provided with PE bar in second cavity, is equipped with gum-injecting port above the PE bar.
Further, the straight thread reinforced bar and straight screw sleeve are to be threadedly coupled.
Further, the straight screw sleeve is equipped with several.
Compared with the existing technology, a kind of assembled staircase structure described in the utility model has the advantage that
The utility model easy construction can accelerate the speed of construction, improve the efficiency of construction, reduce cost, using straight
Screw shell realizes the accurate positionin of straight thread reinforced bar and waist slab, improves the convenience of construction, it is accurate that later period grouting facilitates.
