Abstract
The superelevation beam-column type bracket, including basis, buttress on basis is set, it is provided with stringer on buttress and is used to support crossbeam, crossbeam is for carrying template, buttress at bridge pier is double-row steel pipe column, uses I-steel lateral connection and oblique connection between every steel pipe column of direction across bridge, along bridge to every steel pipe column between use the longitudinally connected and oblique connection of I-steel.Double-row steel pipe column is set as by the buttress at bridge pier, and steel pipe column direction across bridge to the double-row steel pipe column and entire beam-column type bracket and along bridge to using I-steel lateral connection and oblique connection, form it into grid-system, the overall stability of structure is increased, support cast-in-place construction safely can be carried out to superelevation superelevation bridge.
Description
Technical field
The present invention relates to a kind of superelevation support cast-in-place box-beam structures under complicated landform.
Background technique
The construction technology of domestic high speed railway box girder is varied according to address, the environmental factor difference of bridge, mainly
There are raft support method, MSS method, prefabrication and lifting method and steel pipe, fashioned iron and Bailey beam sectional shelf-unit method, but raft support method
Be primarily adapted for use in the place that ground is good, construction space is unrestricted, MSS method and prefabrication and lifting method be primarily adapted for use in high-volume,
Standard mass concrete construction.But High-Speed Railway Bridge Construction frequently encounter Bridges in Mountainous Areas construction, bridge pier is higher, scene again not
Have the above common beam condition processed, if using modular support cast-in-place construction, and it is difficult to ensure the safety of in-situ beam casting
And high efficiency.
It is too small for clear distance between certain bridge box and beams, Construction Through Form on Traveler can not be used, can only be constructed using support cast-in-place,
And bridge pier is excessively high, is higher than safe altitude defined by all about high-speed railway cast-in-place box beam bracket in prior art regulation.
In this case it is necessary to a kind of superelevation supporting structure, guarantee under the premise of safety and stability to superelevation bridge into
The cast-in-place construction of row box beam.
Summary of the invention
The present invention provides a kind of superelevation beam-column type bracket structure, guarantee under the premise of safety and stability to superelevation bridge into
The construction of row support cast-in-place.
The buttress on basis is arranged in a kind of superelevation beam-column type bracket, including basis, and stringer use is provided on buttress
In support beam, for crossbeam for carrying template, the buttress at bridge pier is double-row steel pipe column, between every steel pipe column of direction across bridge
Using I-steel lateral connection and oblique connection, along bridge to every steel pipe column between use the longitudinally connected and oblique company of I-steel
It connects.
It is set as double-row steel pipe column by the buttress at bridge pier, and to the double-row steel pipe column and entire beam-column type bracket
Steel pipe column direction across bridge and along bridge to I-steel lateral connection and oblique connection is used, form it into grid-system, increase finishes
The overall stability of structure safely can carry out support cast-in-place construction to superelevation bridge.
Detailed description of the invention
Fig. 1 is that the superelevation beam-column type bracket tower sets vertical disconnected plan view.
Fig. 2 is the cross-section diagram in Fig. 1 along the direction A-A.

Specific embodiment
As depicted in figs. 1 and 2, the superelevation beam-column type bracket, including basis, are arranged in the buttress on basis, buttress it
On be provided with stringer and be used to support crossbeam, crossbeam is for carrying template, and the buttress at bridge pier is double-row steel pipe column, direction across bridge
I-steel lateral connection and oblique connection are used between every steel pipe column, along bridge to every steel pipe column between it is vertical using I-steel
To connection and oblique connection.It is set as double-row steel pipe column by the buttress at bridge pier, and to the double-row steel pipe column and entirely
The steel pipe column direction across bridge of beam-column type bracket and suitable bridge form it into lattice body to I-steel lateral connection and oblique connection is used
System, increases the overall stability of structure, safely can carry out support cast-in-place construction to superelevation superelevation bridge.
Below to a specific embodiment for locating the invention.
The superelevation beam-column type bracket system, from top to bottom successively using I 20a I-steel, Bailey truss, I 45a I-steel,
Movable end, steel pipe column, pier cap basis or basic using C25 reinforced concrete strip foundation staking.Strip footing having a size of
2.2 × 1.0m buries 0.8m × 0.8m, is provided with the connection structure of the steel plate and anchor bolt of thick 2cm as steel pipe column, pile foundation is
The drilled pile of diameter 1.0m, it is each setting drilled pile strip footing under 4 pile bases are set.
The connector vertical bar of Bailey truss should be arranged at fulcrum as far as possible, in favor of stress；When Support Position cloth is in Bailey beam
When on node, vertical V-arrangement tilting bar should be reinforced, truss is reinforced；Bailey truss should all be reliable using U-shaped card with distribution beam
Connection, is stoppered between bracket and pier shaft with the lumps of wood, must reinforcement processing at the top of steel column.
Along steel pipe column axis direction every 6m between direction across bridge steel pipe column, and away from 50cm at the top of steel pipe column, with I 20a
I-steel is as lateral connection and oblique connection；Along bridge to steel pipe column axis direction suitable between two rows of steel pipe columns every 6m, and away from
50cm at the top of steel pipe column, uses I 20a I-steel as lateral connection and oblique connection；And two rows of steel pipe columns by the bridge pier it
Between along steel pipe column axis direction every 6m, use I 20a I-steel as sustaining wall and connect together with pier shaft.
The stull of sustaining wall I-steel is connect using hinged with pier shaft；The height of steel pipe column be 40 meters or more, all steel pipe columns from
30m or less fills out core using C30 concrete.
