Technical field
The present invention relates to the underground structure technical field of rail traffic, more particularly, to station accessory structure foundation pit power transmissions
The short support construction of steel and construction method of component.
Background technology
Subway station accessory structure (Ru Fengting, entrance etc.) construction carries out after generally binding at main body station, attached knot
Structure construction is set up often by the building enclosure of agent structure foundation pit supports the construction for carrying out excavation of foundation pit and accessory structure, and
Accessory structure and the connecting portion of agent structure set post-cast strip, but need in post empiricism first to cut the main body of connecting portion
Fender post, the support needs between accessory structure fender post and main body fender post are removed before being poured in post-cast strip, accessory structure base
The outer lateral earth pressure in hole is acted on accessory structure, and because post-cast strip is not constructed also, accessory structure is not yet connected as a single entity with agent structure,
There are the risks of sidesway for accessory structure fender post.Currently used method is to be applied below accessory structure bottom plate and bottom plate entirety
Power is transferred on the fender post below bottom plate by the armoured concrete slab poured, then cuts top fender post；And in structure roof
First of support of side needs to directly act on agent structure beam.This method complex procedures, and agent structure beam is set
Meter also needs to consider the lateral force of accessory structure foundation pit, and very big inconvenience is all brought to design and construction.
It is currently used to apply and the armoured concrete slab of bottom plate one-piece casting or pushing up below accessory structure bottom plate
First of support of setting is directly acted on agent structure beam above plate, and construction is more complicated, is unfavorable for execute-in-place.
Invention content
In view of the drawbacks described above of the prior art, technical purpose of the invention is to provide the use that a kind of attached foundation pit is stablized
In the short support construction of the steel of station accessory structure foundation pit Force transmission parts and construction method.
In order to achieve the above objectives, present invention employs following technical proposals：One kind of the present invention is used for station accessory structure
The short support construction of steel of foundation pit Force transmission parts, the short support tectonic level setting of steel, the short support construction of steel are arranged in post-cast strip,
Contact surface of the short support construction both ends of steel respectively with station agent structure and station accessory structure is held out against, the attached knot in station
Structure is made of top plate and bottom plate, and the short support construction of steel sets the lower edge of the top plate of accessory structure and bottom plate AT STATION, the top
Plate and bottom plate lower edge are provided with reinforcing bar, and the short support construction of steel carries out spot welding with reinforcing bar and fixes.
Further, the short support of the steel is configured to I-steel or steel pipe.
Further, pick up the car the 1/2-1/ of station accessory structure top plate and bottom plate for the position of the supporting point of the short support construction of the steel
At 3.
Further, the post-cast strip is reserved with waterstop, the short support construction of steel AT STATION accessory structure b top plates and
The waterstop that post-cast strip is reserved is avoided in the thickness range of bottom plate.
The present invention also provides a kind of steel for station accessory structure foundation pit Force transmission parts it is short support construction construction method,
Include the following steps：
(1) between attached fender post and main body fender post, first of support and second support are set up, with digging with support
It opens, digs to foundation pit bottom surface；
(2) the attached bottom plate of construction in foundation pit after more than 75% reach design strength, sets up the short support construction of steel, and remove
Second supports；
(3) it constructs attached side wall and attached top plate, after more than 75% reach design strength, sets up the short support construction of steel, and
Remove first of support；
(4) main body fender post, Construction Later Casting Zone are cut.
Beneficial effects of the present invention：
Stable structure of the present invention is reliable, simple in structure, and making is easy for construction, at low cost, for the power transmission of deep basal pit post-cast strip
In, agent structure entirety stress is good, ensure that main body fender post is cut and during supporting removal, attached foundation pit is stablized, and avoids
The accessory structure sidesway poured in advance.
