Two half space 305 turnover L-type connects, and in Fig. 2, positive second staircase boards 302 and lateral third story gangboard 303 turning point are formed
Space be vertical lift space 4, the second staircase boards 302 lower end and the first half space 304 junction setting stair stringer 306 and
The newel 307 of two support stair stringers, newel 307 is located at stair stringer 306 two ends, the second half space 305 and third story ladder
Plate 303 junction setting stair stringer 306 and newel 307, in Fig. 2, the second staircase boards 302 and lateral third story gangboard 303 are transferred
Place is provided with the newel 307 of two stair stringers 306 and lower section.Turning point newel often takies platform function room area, laterally
Newel below the staircase boards space formed below with positive staircase boards can directly be closed in finishing, incline and account for platform passageway,
So that stair underlying space is not fully utilized, impact station permeability, lofty Mechanical Builds have a strong impact on station attractive in appearance and
Building uses function.
Content of the invention
The purpose of this utility model seeks to solve the deficiency of above-mentioned background technology, provides a kind of convenient construction, construction letter
Semi-mounted stair under subway station plate that is single, cancelling side coil newel, increased platform public use spatial dimension, improve ground
The attractive in appearance and security performance at ferrum station.
The technical solution of the utility model is：Semi-mounted stair under a kind of plate of subway station, including from platform slab successively upwards
Forward direction first staircase boards of setting, the second staircase boards, lateral third story gangboard are logical between described first staircase boards, the second staircase boards
Cross the first half space to connect, the second staircase boards and third story gangboard pass through the second half space transition junctions it is characterised in that
It is provided for supporting the support column of stair stringer below setting stair stringer and stair stringer on described second staircase boards, middle plate is down-set
Hang wall, described third story gangboard lateral surface is connected on extension wall.
Preferably, described Gua Qiang cross section be inverted L shape, wherein the horizontal component of inverted L shape Gua Qiang upper end stretch out laterally with
The middle plate-girder of middle plate connects, and the vertical portion of lower section is connected with third story gangboard lateral surface.
Further, horizontal component internal reinforcing bar in described Gua Qiang upper end is connected with reinforcing bar binding in middle plate-girder.
Further, below described extension wall, the internal reinforcing bar of vertical portion is connected with reinforcing bar binding in third story gangboard.
Preferably, described stair stringer is located at the second staircase boards between the upper and lower ends.
The beneficial effects of the utility model are：
1. eliminate the side newel between the second staircase boards and third story gangboard, solve excessive newel and occupy platform
The use function of spacial influence platform and the problem of aesthetic.
2. the mode hanging wall had both ensured stair bonding strength, overcomes cranked slab stairs (stringer type stairway) and cancels side stair
Post is likely to result in the problem of staircase structure potential safety hazard, decreases the impact to station layer for the stair beam column again, improves passenger's
Comfort level and the utilization ratio in station space.
3. this utility model has the advantages that design is simple, construction is convenient, ensure that structure is safe, in agent structures such as subways
Engineering field has preferable application prospect.
