Description of the drawings

Fig. 1 is the structural representation of this utility model new steel structure shelter bridge base structure.

In figure, 1. bridge post, 2. bridge pier, 3. horizontal binder, 4. girder steel, 5. bridge floor, 6. bearing, 7. cushion cap, 8. basic.

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 new steel structure shelter bridge base structure, referring to Fig. 1, including two rows being set up in parallel Bridge pier 2 and the bridge floor 5 above bridge pier 2, are provided with corridor room above bridge floor 5.Near the one of 5 bottom of bridge floor on each bridge pier 2 End is connected by beam lattice architecture in length and breadth.Beam lattice architecture includes several girder steels 4 in length and breadth.Wherein, girder steel 4 is according to following Structure setting：Move towards to connect by girder steel 4 between each bridge pier 2 for arranging along bridge floor, edge is moved towards vertical direction with bridge floor and set Connect also by girder steel 4 between the bridge pier two-by-two 2 put.

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 5 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 5 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 5 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 5 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 5 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 5 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 5 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 5, 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 5, 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 girder steel 4, and along the direction vertical with bridge floor 9, longeron arranges that crossbeam is along bridge floor 9 Move towards arrangement.As each bridge post 1 runs through in the agent structure of bridge floor 5 and each layer of corridor room of shelter bridge, so from bottom to up The integral structure shelter bridge of abutment under upper frame has been constructed just.So, the load in every layer of corridor room is just by accordingly in length and breadth Joist support is carried on a shoulder pole, and by per layer of beam in length and breadth by load transfer to bridge pier 2 so that the Integral Loading of shelter bridge is born by bridge pier 2, and Bridge floor 5 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 concrete bridge post 1 is constructed to upwards at the position of 5 bottom of bridge floor, then will The built-in fitting of steel construction is nuzzled the top of each bridge post 1 in advance, then with girder steel 4 by the built-in fitting connection at the top of each bridge post 1 shape Into beam lattice architecture in length and breadth, then each girder steel 4 is linked together with corresponding bridge post 1 by concrete casting；Finally, exist Frame structure corridor room is built on bridge floor 5, specially：Each bridge post 1 continues up construction, and through connection shelter bridge bridge floor 9 to In the agent structure in every corridor room, by the adjacent upright posts between the two neighboring column in corridor room, and/or two neighboring corridor room it Between by girder steel 4 connection form frame structure.

To sum up, bridge structure under the exclusive upper frame of this utility model is material is thus formed, wherein beam lattice system is tied in length and breadth Frame structure between structure and corridor room is steel construction.The load of shelter bridge is just transformed into bridge post 1,2 and of bridge pier successively by girder steel 4 On basis 8, and bridge floor 5 is not subject to load so that beam thickness can be far smaller than that the beam of common shelter bridge is thick.And, this utility model The structure on each 1 top of bridge post is connected using girder steel 4, the engineering time can be caused to shorten；Meanwhile, it is being unsuitable for taking completely in river surface Where hall frame, shelter bridge basis is built using this utility model new steel structure shelter bridge base structure, deep water can be solved and be applied A difficult problem for work.
