Description
Technical field
The utility model is related to staircase structure, more particularly to applicable scissor stair structure when a kind of floor height is relatively low.
Background technology
Cantilever stair also referred to as overlaps stair, intersects stair or set ladder, is usual between linking building floor
One of form.It is in a pair of two overlapped and not connected stair of same staircase setting.In the bench of its staircase
Generally single flight vertical ladder section.The most important feature of cantilever stair is that two stair are provided in same staircase, has two
The function of vertical direction fire escape.In planar design, using the space of relatively narrower, two stair are arranged in cantilever stair, this
Two stair adhere to two different fire compartments separately, thus improve construction area utilization rate.It is most to save space, most at present
Passageway for fire apparatus that is economic, most can rationally meeting the requirements again, has reached benefit.
The Chinese patent that notification number is CN205134795U disclose a kind of floor height it is relatively low when applicable scissor stair structure,
It includes lower layer's ladder beam, upper layer ladder beam and gangboard, by rolling over beam connection between lower layer's ladder beam and upper layer ladder beam；Described
Gangboard is made of 5mm thickness checkered steel plates, which is anchored on folding beam.Applicable scissor stair structure when this floor height is relatively low
Although simple in structure, reasonable design, efficiently avoid conventional shears staircase structure be only applicable to floor height it is higher when the case where,
Safeguard procedures are few, intersect be easy at stair because the stream of people is crowded or other reasons to cause personnel to fall the safety such as stair hidden
Suffer from, it would be highly desirable to solve.
Utility model content
The purpose of this utility model be to provide a kind of floor height it is relatively low when applicable scissor stair structure, there is protective device to increase
Add the effect of stair safety.
The above-mentioned technical purpose of the utility model technical scheme is that：It is suitable when a kind of floor height is relatively low
