Description
Technical field
The utility model relates to bridge structure technical fields, and being suitable for two sides in particular to one kind is that long the United Nations General Assembly's stroke is public
Iron is layered bridge pier beam integrated structure.
Background technique
It requires larger for span and is the bridge location deeper across a wide range of waters, the depth of water, foundation engineering often accounts for throwing
More than half for providing total value need to reduce pier in water to the greatest extent and number is arranged.Region span arrangement conventional at present is all difficult to be applicable in,
It generally requires using the long connection continuous arrangement form of Loads of Long-span Bridges.Rail-road is layered in science of bridge building, using existing for the arrangement form
Problem be long connection Loads of Long-span Bridges continuously be arranged cause temperature across length, the setting of rail temperature expansion and cotraction regulator is difficult, beam-ends corner is superimposed
Lead to supergage limit value.When solving the above problems at present, conventional way and existing some problems are as follows:
1, for general layout, beam-ends corner is caused to be superimposed supergage limit value to avoid two long connection Loads of Long-span Bridges from being continuously arranged
Problem, between two long connection Loads of Long-span Bridges, add 1~2 transition across, increase pier number in water, for guarantee one of them or it is more
A hole is required across navigation, need to adjust remaining hole across ratio, terrain adaptability is poor.
2, bridge is layered for rail-road, causes beam-ends corner to be superimposed supergage to avoid two long connection Loads of Long-span Bridges from being continuously arranged
Limit value problem can also be taken greatly across the continuous structural arrangement form of multitower.Bridge structure across multitower greatly, often to each hole across ratio
There is strict demand, it is contemplated that the factors such as integral arrangement, bridge tower stress, structure ballast, it is desirable that each main aperture is smaller across difference, is
Meet one of hole across requiring, often needs to increase other holes across span, so that the structure entirety scale of construction is excessive, bridge structure rigidity
It is low.
3, difficult, solution is set across length, rail temperature expansion and cotraction regulator to solve the problems, such as that length joins Loads of Long-span Bridges temperature
Articulated manner is used in bridge tower position for beam portion, increases setting beam and stitches, the program can effectively solve temperature across long problem, but drop
The low ride comfort of train and automobilism, and articulated position structure beam-ends corner is difficult to control, and largely reduces structure
Overall stiffness.
Summary of the invention
The purpose of this utility model seeks to the existing long connection Loads of Long-span Bridges for solving to mention in above-mentioned background technique, and there are bridges
The problem that pier is excessive, bridge stiffness is low, ride comfort is poor, providing one kind to be suitable for two sides is that long the United Nations General Assembly's stroke rail-road is layered bridge pier
Beam integrated structure.
The technical solution of the utility model are as follows: it is that long the United Nations General Assembly's stroke rail-road is layered the combination of bridge pier beam that one kind, which is suitable for two sides,
Structure, the bridge pier including cushion cap and on cushion cap, it is characterised in that: further include pier beam adapter section and beam portion；The pier
Beam adapter section is to pour the reinforced concrete structure for being fixed on bridge pier upper end, and pier beam adapter section includes to both ends along bridge for supporting
The beam section support portion of the long the United Nations General Assembly's stroke beam in two sides and the intermediate beam portion support portion for being used to carry beam portion；The beam portion is fixed on
For being connected long the United Nations General Assembly's stroke beams of two sides on beam portion support portion, beam portion is along bridge to long the United Nations General Assembly's stroke beam at both ends and two sides
Between there are expansion joint, beam portion includes the upper deck of bridge being connected with long the United Nations General Assembly's stroke beam upper layer highway bridge and stretches with long the United Nations General Assembly
Lower layer's bridge floor of Suo Liang beam lower layer's railway deck linking.
The suitable bridge that the further beam section support portion is fixed on beam portion support portion is formed to side and beam portion support portion
Up big and down small and upper end area is greater than the pyramidal structure of bridge pier cross-sectional area.
The bridge floor area of the further upper deck of bridge is greater than the bridge floor area of lower layer's bridge floor, upper deck of bridge and lower layer
The web member being arranged in a vertical direction and the diagonal brace being vertically in tilted layout are provided between bridge floor；The web member lower end is fixed on
The direction across bridge side of lower layer's bridge floor, upper end are supported in the lower end surface of upper deck of bridge；The diagonal brace upper and lower ends are respectively supported at
The direction across bridge side of upper deck of bridge and lower layer's bridge floor.
The beam portion along bridge to length be 20~50m.
The pinner that long the United Nations General Assembly's stroke beam is shelved is disposed on the further beam section support portion.
The advantages of the utility model, has: 1, the pier beam integrated structure, realizes that two sides are that long the United Nations General Assembly's stroke rail-road is layered bridge
Drop-over cancels the transition between when routine is arranged across structure arrangement effectively reduces bridge pier and basic quantity, economic performance are good
It is good；
2, the pier beam integrated structure terrain adaptability is strong, requires especially for span compared with a wide range of waters of Great span, the depth of water
Deeper bridge location can overcome disadvantage present in conventional span distribution, for special bridge location design provide it is a kind of completely new
Structural arrangement form reference；
3, the pier beam integrated structure structure is simple, and adaptability is good, can facilitate and urban environment ecology rapid fusion；
4, the pier beam integrated structure dexterously solves long connection Loads of Long-span Bridges by a series of measures generation continuously be arranged
A series of problems effectively promote bridge hole across integral arrangement, and safety that structure is reasonable, economic benefit is good, is a kind of be worth
The structure type being widely popularized.
