Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail.
This utility model provides a kind of Novel gallery bridge concrete foundation structure, referring to Fig. 1, including two rows being set up in parallel
Bridge pier 2 and the bridge floor 9 above bridge pier 2, are provided with corridor room above bridge floor 9.Near the one of 9 bottom of bridge floor on each bridge pier 2
End is connected by beam lattice architecture in length and breadth.Beam lattice architecture is included by prestressed frame beam 5 and Vierendeel girder 4 in length and breadth, wherein,
Prestressed frame beam 5 moves towards arrangement along bridge floor and connects each bridge pier 2, and Vierendeel girder 4 will move towards vertical bridge two-by-two with bridge floor
Pier 2 connects.
As shelter bridge load-bearing is than larger, and highway bridge load-bearing is less, if directly built above existing highway bridge
If corridor room, the load of common road bridge floor can be caused to increase 35-40 times, necessarily so that its beam thickness is greatly increased, resulted in
When the beam bottom of highway bridge and shelter bridge is in same plane, the bridge floor of the bridge floor and shelter bridge of highway bridge is difficult to be in sustained height.
If the fine strain of millet of bridge floor 9 is thicker than height, the abutment at shelter bridge two ends will be very high, then need to build higher step by bridge and ground
Connection, gives people the current shelter bridge of car and causes difficulty.
It is and in this utility model, will be connected by beam lattice architecture in length and breadth between bridge post 1 two-by-two, and mixed using reinforcing bar
Solidifying soil is poured and is formed so that form firm tower structure between each bridge post 1, and the load undertaken on bridge floor 9 can pass through
This in length and breadth beam lattice architecture be transferred on bridge pier 2, and bridge floor is not subject to, so so that the beam thickness of bridge floor 9 can be much
It is thick less than the beam of common shelter bridge so that when the beam bottom of shelter bridge and highway bridge is located at same level, the bridge floor of highway bridge and
The bridge floor of shelter bridge is also at sustained height, it is ensured that the overall planarization in road surface.
By taking the shelter bridge of 20 meters of across footpaths as an example, due to 35～40 times that the load of shelter bridge is common road bridge, if according to general
The structure design of bridge accessible by road, then the fine strain of millet thickness of bridge floor 9 need to be designed as 2.5～3 meters, and adopt the application new steel structure shelter bridge
The structure of base structure, the fine strain of millet thickness of bridge floor 9 only need to be designed as 0.8～1 meter, greatly save the cost of shelter bridge.
The basis 8 of underwater foundation is connected to below each bridge pier 2 by cushion cap 7；Each 2 epimere of bridge pier is bridge post 1, each
Girder steel 4 is all connected between each bridge post 1, is connected to the bottom of bridge floor 9 above each bridge post 1 by bearing 6.Walk with bridge floor on edge
Horizontal binder 3 is connected between the post of bridge two-by-two 1 arranged to vertical direction.Horizontal binder 3 can increase by two bridge posts 1
Between stability.
Each bridge post 1 is from bottom to up through the agent structure of the bridge floor 9 and each layer of corridor room of connection shelter bridge.Wherein corridor room
Agent structure includes several steel structural upright columns, girder and secondary beam, and each column is parallel with bridge post 1, girder and secondary beam and bridge post 1
Vertically.
When a corridor room is arranged on bridge floor 9, connected by longitudinal and cross beam between the two neighboring column in corridor room
Form frame structure；It is when the corridor room of two or more than two is arranged side by side on bridge floor 9, two neighboring vertical in every corridor room
Between post, and the adjacent upright posts in adjacent two corridors room between connect to form frame structure by longitudinal and cross beam.
Wherein, longitudinal and cross beam is Vierendeel girder and passes through concreting together, and longeron is along vertical with bridge floor 9
Direction arrange, crossbeam along bridge floor 9 move towards arrangement.As each bridge post 1 is from bottom to up through the bridge floor 9 and each layer of shelter bridge
In the agent structure in corridor room, the integral structure shelter bridge of abutment under upper frame has thus been constructed.So, every layer of corridor room
Load just by joist support load in length and breadth accordingly, and by per layer of beam in length and breadth by load transfer to bridge pier 2 so that shelter bridge it is whole
Body load is born by bridge pier 2, and bridge floor 9 is not subject to so that beam thickness can be far smaller than that the beam of common shelter bridge is thick.
A kind of construction method of new steel structure shelter bridge base structure of this utility model is：First on request bridge foundation,
I.e. cushion cap and bridge pier etc. are built up；Again each bridge post 1 is constructed upwards at the position of 9 bottom of bridge floor, prestressed frame is used
Each bridge post 1 is connected and is formed beam lattice architecture in length and breadth by beam 5 and Vierendeel girder 4, then each is pre- by concrete casting
Stress-frame specimen set a roof beam in place 5 and Vierendeel girder 4 link together with corresponding bridge post 1；Finally, frame structure corridor room is built on bridge floor 9, have
Body is：Each bridge post 1 continues up construction, and in the agent structure in 9 to every corridor of bridge floor room of connection shelter bridge, will per
Connect to be formed by Vierendeel girder between two neighboring column in corridor room, and/or between the adjacent upright posts in two neighboring corridor room
Frame structure.
To sum up, material is thus formed the xoncrete structure of bridge under the exclusive upper frame of this utility model.The load of shelter bridge
Just be transformed on bridge post 1, bridge pier 2 and basic 8 successively by each Vierendeel girder, and bridge floor 9 be not subject to load so that Liang Houke with
The beam of far smaller than common shelter bridge is thick.
