To achieve the above object, the utility model provides a kind of steel structure stairway, including stair cushion cap, and stair cushion cap is set
Have bending place, the first stress point be provided with the outside of bending place, be provided with the second stress point above the first stress point, first by
Drawing is connected between force and the second stress point, between the top of stair cushion cap, stair cushion cap upper end and the second stress point
Rope, the drag-line above stair cushion cap is crossed to form joint in bending place respectively, between the first stress point and the second stress point
Also drag-line is connected between drag-line and joint.
Alternatively, outwardly extending girder steel is provided with the outside of bending place, the first stress point is arranged on girder steel.
Alternatively, girder steel is arranged to horizontal horizontal structure.
Alternatively, the first stress point is arranged on the outside end of girder steel.
Alternatively, the drag-line above stair cushion cap holds that edge of table is parallel with stair, the edge of stair cushion cap and its
Interval is connected with the railing of multiple vertical directions between the drag-line of top.
Alternatively, the second stress point is arranged on beams of concrete.
Alternatively, beams of concrete is arranged to the right-angle structure that right angle is located at upper right side.
Alternatively, the second stress point is arranged on the lower end of beams of concrete.
Alternatively, step is provided with stair cushion cap, railing is arranged at the outer ledge of stair cushion cap.
Alternatively, drag-line is arranged to prestress rope.
The utility model method has the following advantages that：
The steel structure stairway of the utility model, to solve force structure complexity, the occupied space in the presence of the prior art
Greatly, of high cost, the cumbersome, low construction efficiency of construction, from great and span it is small the problems such as, its force structure is reasonable, saves space, into
This is low, and easy construction is quick, and dead weight is small, and span is big, suitable for having to space in the building of particular/special requirement, is also applied for room
Outside.
Brief description of the drawings
Fig. 1 is the structure diagram of the steel structure stairway of the utility model.
In figure, 1 is stair cushion cap, and 2 be step, and 3 be bending place, and 4 be the first stress point, and 5 be the second stress point, and 6 be drawing
Rope, 7 be girder steel, and 8 be beams of concrete, and 9 be railing.
Embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment
A kind of steel structure stairway, as shown in Figure 1, including stair cushion cap 1, stair cushion cap 1 is provided with bending place 3, bending place 3
Outside be provided with the first stress point 4, the top of the first stress point 4 is provided with the second stress point 5, the first stress point 4 and second
Drag-line 6, building are connected between stress point 5, between the top of stair cushion cap 1,1 upper end of stair cushion cap and the second stress point 5
The drag-line 6 of the terraced top of cushion cap 1 is crossed to form joint in bending place 3 respectively, between the first stress point 4 and the second stress point 5
Also drag-line 6 is connected between drag-line 6 and joint.
As it can be seen that the steel structure stairway of the present embodiment, it is propped up by the prestressing force effect between stress point and drag-line 6
Support, power is delivered to another stress point by a stress point by drag-line 6, stair cushion cap 1 is drawn by it by varying stress point
Firmly, its overhanging type structure, can realize the transmission of power, can reduce or without load-bearing pillar, reduce the usage amount of steel, its into
This is low, and construction is fast, and easy to build, dead weight is small, and span is big, can be applied to have in the building of particular/special requirement space, also fits
For outdoor.
The steel structure stairway of the utility model, can further include such as lower structure：The outside of bending place 3 sets oriented
The girder steel 7 of outer extension, the first stress point 4 are arranged on girder steel 7.Girder steel 7 is arranged to horizontal horizontal structure.First stress point 4
It is arranged on the outside end of girder steel 7.Girder steel 7 is arranged to cylindrical beam body.Second stress point 5 is arranged on beams of concrete 8.Coagulation
Native beam 8 is arranged to the right-angle structure that right angle is located at upper right side.Second stress point 5 is arranged on the lower end of beams of concrete 8.Drag-line 6 is set
It is set to prestress rope.The drag-line 6 of the top of stair cushion cap 1 can be parallel with the edge of stair cushion cap 1, stair cushion cap 1
