Description
Technical field
The utility model relates to a kind of foot bridges for opening bridge deck for having both piping lane function.
Background technique
Various Option of Piping across Bridge are considered in municipal administration Bridge Design at present.The design scheme of newly building bridge Option of Piping across Bridge is basic
Have following several:
(1) the big pipe such as feed pipe passes through from the vane position evacuated under pavement, i.e. pumping Liang Guoguan；(2) feed pipe etc.
Big pipe is set to outside bridge；(3) pipelines such as telecommunication cable and distribution cable are under side walk slab or the position taken out passes through；(4) by
It is limited in by bridge type and across footpath, some pipelines can not pass through from bridge, need to build special pipe bridge for Option of Piping across Bridge, will both manage
Line is suspended on outside bridge, and pipeline support structure is connect with bridge web or top flange cantilever end, or the bar planting on bent cap, pours one section
Cantilever end is for Option of Piping across Bridge.
Line gap bridge is crossed at present is primarily present following problems:
(1) bridge is unable to satisfy the needs of pipeline dilatation.The bridge built up is needed to lay gap bridge pipeline
First remove bridge certain components, to pipelining after pour again.The way not only causes a large amount of fund to waste, and
And urban operating mechanism is again and again teared down and built, and also results in adverse effect to city；
(2) pipeline is placed on outside bridge, influences urban landscape.Upper part scheme is that pipeline is placed on to bridge structure body
Outside, which influences urban landscape；
(3) maintenance of gap bridge pipeline is more difficult.Since pipelining is in bridge structure body, repair more difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of foot bridge for opening bridge deck for having both piping lane function, structure is tight
It gathers, facilitates the maintenance of the dilatation of gap bridge pipeline and gap bridge pipeline.
The technical solution of the utility model is: a kind of foot bridge for opening bridge deck having both piping lane function, including
The girder of laterally spaced setting is provided with bottom plate between the bottom of adjacent two girder, positioned at the top of adjacent two girder
Between be provided with top plate with girder releasable connection, the region surrounded between adjacent two girder with corresponding bottom plate and top plate is formed
Chamber for laying the line.
Further, the side wall of the girder is provided with to be provided on the bracket and/or bottom plate for laying the line and be used for
The mounting base laid the line.
Further, the both sides of the top plate are longitudinally spaced is provided with counterbore, the edge of a wing setting at the top of the girder
There is the bolt for passing through counterbore from bottom to top, the nut for fixing top plate is bolted on the bolt, blocking in the counterbore has
The rubber sleeve that can be pulled out.
Further, shear connector is evenly equipped on the top plate, the both sides of top plate are additionally provided with hanging ring.
Further, by box or I-shaped and be made of steel, the top plate is coagulation local soil type in the section of the girder
Plywood.
Further, the both sides of the bottom plate mutually weld with girder lower end respectively or are connected through bolt with girder lower end
It connects, draining hole is evenly equipped on bottom plate.
Further, the bottom plate is made of steel plate.
Compared with prior art, the utility model has the advantage that this had both piping lane function opens bridge deck
The bridge deck of foot bridge can open, facilitate maintenance personal to overhaul；It is capable of providing the space of pipeline dilatation in beam body, facilitates pipeline
Dilatation.
Detailed description of the invention
Fig. 1 is the foot bridge structural schematic diagram of the utility model；
Fig. 2 is the top board structure schematic diagram of the utility model；
Fig. 3 is the top plate of the utility model and the removable structure schematic diagram of girder；

Specific embodiment
In order to make the above-mentioned features and advantages of the utility model more obvious and understandable, special embodiment below, and cooperate attached drawing,
It is described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Fig. 4
A kind of foot bridge for opening bridge deck having both piping lane function, foot bridge are mutually indepedent with vehicular bridge.Foot bridge
Girder 1 including laterally spaced setting is provided with bottom plate 3 between the bottom of adjacent two girder, is located at adjacent two girder
Top between be provided with top plate 2 with girder releasable connection, surrounded between adjacent two girder with corresponding bottom plate and top plate
Region formed for lay the line 4 chamber 14.
In the present embodiment, in order to preferably install pipeline, the side wall of the girder is provided with the bracket for laying the line
5 and/or bottom plate on be provided with mounting base 51 for laying the line.
In the present embodiment, the both sides of the top plate are longitudinally spaced to be provided with counterbore 7, and the edge of a wing at the top of the girder is set
It is equipped with the bolt 6 for passing through counterbore from bottom to top, the nut 10 for fixing top plate, envelope in the counterbore are bolted on the bolt
It is stifled to have the rubber sleeve 11 that pulled out, prevent nuts and bolt from getting rusty by the closure of rubber sleeve, and prevent sundries from entering in counterbore.
When needing bridge floor to open (when i.e. top plate is opened), rubber sleeve is pulled out, nut is unscrewed, top plate is sling i.e. using minor crane
It can.
In the present embodiment, in order to improve the connection between top plate steel and concrete, shearing resistance company is evenly equipped on the top plate
Fitting 8.In order to preferably open top plate, the both sides of the top plate are additionally provided with hanging ring 9.
