Description
Technical field
This utility model relates to railway traffic engineering, goes out in particular to a kind of subway gateway
Ground surface platform reinforcement structure.
Background technology
In prior art, subway gateway goes out the usual way of ground surface platform and is, structure discipline root
Require to design to the strong point on building, gateway staircase according to building function, and the design of landing slab
Complete design drawing is required according to function and finishing by architectural discipline.Owing to architectural discipline sets
Soil properties under landing slab is understood the most deep enough by meter personnel, especially on East China weak soil ground
District, gateway landing slab of constructing again after structure personnel complete building staircase knee wall, easily occur
Differential settlement between gateway landing slab and building staircase knee wall, causes building on landing slab
Build finishing surface layer cracking, even have influence on gateway use and the pedestrains safety that comes in and goes out is asked
Topic.
For the problems referred to above, although part designing unit takes enters soil layer under landing slab
The processing scheme of row lime-soil cushion, or take landing slab with building staircase headwall bar planting even
The mode connect.As shown in Figure 1-2, passenger rises to stair from underground by gateway stair 4
Landing slab 9, landing plate 9 supported by stair support column 8 and with building staircase knee wall 2
Connecting, staircase knee wall 2 both sides, building connect a side wall 7, bottom connects that there is any discrepancy mouth base plate
6, it is provided with bar planting junction A between gateway landing slab 1 and building staircase knee wall 2, comes in and goes out
Mouth landing slab 1 is below for change the grey soil layer 5 filled out, and gateway landing slab 1 upper strata is finishing face
Layer 3.In said structure, soft clay area ash soil layer 5 the most easily settles, and bar planting is even
The mode that connects only strengthens the globality of gateway landing slab and building staircase knee wall, but solum settlement
Time still can ftracture, so relative settlement problem between the two can not be solved all the time at all.
Accordingly, it would be desirable to develop a kind of be avoided that in soft clay area with building staircase headwall produce poor
Different sedimentation go out ground level platform structures.
Summary of the invention
The purpose of this utility model seeks to solve the deficiency of above-mentioned background technology, it is provided that a kind of
A kind of be avoided that in soft clay area and building staircase headwall produce relative settlement subway gateway
Go out ground surface platform reinforcement structure.
The technical solution of the utility model is: a kind of subway gateway goes out ground surface platform and strengthens knot
Structure, including gateway landing slab and building staircase knee wall, staircase knee wall both sides, building are provided with side
Wall, bottom are provided with gateway base plate, it is characterised in that described gateway landing slab is held up with building
Ladder knee wall, gateway base plate one-piece casting molding, be provided with below the landing slab of described gateway
For supporting the supporting construction of gateway landing slab, described supporting construction includes scene 2 entrance side
The outrigger that portion is outwards arranged within the walls, described gateway landing slab is positioned horizontally on two outriggers.
Further, described outrigger and gateway landing slab and building staircase knee wall, gateway
Base plate one-piece casting molding.
Further, in described outrigger, reinforcing bar anchorage depth in side wall is not less than 35 times
The main stress bar diameter of outrigger.
The beneficial effects of the utility model are:
1. gateway landing slab and building staircase knee wall, gateway base plate one-piece casting molding,
Gateway landing slab is integrally formed with building staircase knee wall, the support below the landing slab of gateway
It is firmly supported by structure, it is to avoid differential settlement between the two, and then solves
State the series of problems such as gateway platform surface layer cracking, pedestrains safety.
2. when gateway landing slab length is less than three meters, it is adaptable to propping up of this utility model outrigger
Support structure, it is ensured that gateway landing slab be firmly connected with building staircase knee wall while economy
Higher.
3. this utility model has that design is simple, it is convenient to construct, be avoided that gateway landing slab
With advantages such as building staircase knee wall differential settlements, avoid under existing scheme landing slab simultaneously
The secondary excavation of lime-soil cushion and fill compaction problem, improve construction efficiency, it is ensured that execute
Working medium amount has well application in subway and other municipal administration underground exit and entrance designs
Prospect.

Detailed description of the invention
With specific embodiment, this utility model is made the most below in conjunction with the accompanying drawings
Bright.
Go out ground level platform structures schematic diagram for existing subway gateway as shown in Figure 1-2, exist
Background technology is explained in detail, repeats no more in this.
As shown in Figure 3-4, the subway gateway that the present embodiment provides goes out ground surface platform and strengthens knot
Structure, including gateway landing slab 1 and building staircase knee wall 2, staircase knee wall 2 both sides, building
Be provided with side wall 7, bottom is provided with gateway base plate 6, and gateway stair 4 are connected to stair and put down
Platen 9, landing plate 9 is supported by stair support column 8 and connects with building staircase knee wall 2
Connecing, staircase knee wall 2 both sides, building connect side wall 7 (sidewall structure is identical with Fig. 2),
Bottom connects there is any discrepancy mouth base plate 6, and wherein side wall 7, gateway base plate 6, building staircase support
Wall 2 is one-piece casting molding.
The support knot for supporting gateway landing slab 1 it is provided with below gateway landing slab 1
Structure, supporting construction includes that scene 2 entrance side wall 7 internal outwards (i.e.) is arranged in Fig. 4 to the right
Outrigger 10, gateway landing slab 1 is positioned horizontally on two outriggers 10.Outrigger 10 and discrepancy
Mouth landing slab 1 and building staircase knee wall 2, gateway base plate 6 one-piece casting molding.Outrigger
In 10, reinforcing bar anchorage depth in side wall 7 is not less than main stress reinforcing bar in 35 times of outriggers 10
Diameter d, i.e. anchorage length are not less than 35d.
Outrigger 10, gateway landing slab 1 are integrated with building staircase knee wall 2, even if so
Below gateway landing slab 1, soil layer settles, and outrigger 10 remains on support gateway and puts down
Platen 1 makes it to settle therewith, begins between gateway landing slab 1 and building staircase knee wall 2
It is integrated eventually, it is to avoid rupturing of finishing surface layer 3.
When landing slab length≤3 meter, gateway, it is suitable for the supporting construction of the present embodiment, warp
Ji is efficiently.
