Abstract
The utility model discloses a bridge-building-integrated T-shaped station bridge structure, which comprises a bridge pier, a canopy, track beams and station beams, wherein the station beams are arranged on both sides of the track beams; each station beam further comprises a top plate, and an inner side web plate, a middle web plate and an outer side web plate arranged under the top plate along a track. The bridge-building-integrated T-shaped station bridge structure is characterized in that the top plates over the outer side web plates are provided with canopy columns. The T-shaped station bridge structure disclosed by the utility model meets the erecting construction requirement of the canopy columns, can bear load effects of structural dead weight, wind, temperature, earthquake and the like transmitted down by the canopy columns, and meets the requirement of stress.
Description
Technical field
The utility model relates to bridge construction technical field, is specifically related to the T shape platform bridge construction that a kind of bridge is built unification.
Background technology
It is the new structure system occurring in railway construction that bridge is built unification station.It is neither single building structure, and bridge construction that neither be single, but the structural system combining is built in a kind of bridge and room is station building structure and the Station Bridge girder construction common stressed a kind of station structure pattern that combines.Bridge is built in combined structure system, and platform beams must offer building structure awning and effectively support.
Conventional T beam refers to that cross-sectional form is T-shaped beam, and both sides are chosen part and are called the edge of a wing, and intermediate portion is called web.This structure is the equal of in rectangular beam, the inoperative concrete in tension zone of flexural strength to be cut out to rear formation.Outside identical with original rectangle flexural strength, but both can save concrete, alleviate again the deadweight of member, improve span ability.But conventional T beam be take and born deadweight, two perseverances, vehicular load as main, and its load form all can be considered as the evenly distributed load in certain limit, therefore the web of general T-shaped beam section and edge of a wing size are all less.
Bridge is built vertically on the overhead platform beams of combined structure has an awning post, and platform girder construction transmits by bearing by awning post the loads such as dead load, wind, temperature and geological process that get off, thereby produces huge moment of flexure, shear and torsion.Existing structure cannot be born the internal force (moment of flexure, shearing, moment of torsion) of awning, the outer frange plate of conventional T beam is thinner, and awning post suspension column size is generally larger, also can not meet the structure requirement of pre-buried awning suspension column, therefore existing conventional T beam cannot meet the column requirement of " taking root ".
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, the T shape platform bridge construction that has been to provide a kind of bridge to build unification, and this structure meets the column requirement that bridge is built unification, guarantees the reliable form of structure of structural safety simultaneously.
For solving the problems of the technologies described above, the designed a kind of bridge of the utility model is built the T shape platform bridge construction of unification, comprises the platform beams of bridge pier, awning, rail beam and rail beam both sides; Each platform beams also comprise top board and top board under direction along ng a path interior coxostermum, middle pectoral plate and outer coxostermum are set; On top board directly over described outer coxostermum, be provided with awning post.
Further, between described outer coxostermum and top board, be provided with special-shaped piece, the footnote of described awning post is by inserting on top board in special-shaped piece.
Again further, between described interior coxostermum, middle pectoral plate and outer coxostermum, direction along ng a path is provided with diaphragm.
Again further, the spacing of described awning post direction along ng a path on top board is 10～15m.
Again further, the spacing of described diaphragm is 10～15m, and thickness is 0.5～1.0m.
Again further, described in, being provided with the thickness at web position outside special-shaped piece is 0.6～1.8m.
Again further, the thickness of described special-shaped piece is 1.0～1.8m.
The utility model has the advantage of:
1, T-shaped girder construction of the present utility model meets the structure requirement set up awning post, and can bear by awning post and transmit the load effects such as dead load, wind, temperature and earthquake that get off, meets stressed needs.
2, platform beams of the present utility model outside is set up awning post and will be formed larger moment of torsion to platform beams structure, by thickening dividing plate is set, form good torsional property, makes it have more advantage on stressed.
3, of the present utility model by special-shaped piece is set, met the structure requirement of awning suspension column, make suspension column fixing on platform beams reliably.
Accompanying drawing explanation
Fig. 1 is the T shape platform bridge construction schematic diagram that the utility model bridge is built unification;
Fig. 2 is the plan view of platform beams in figure;
Fig. 3 is the cross-sectional view of platform beams in figure;
In figure, 1. bridge pier, 2. rail beam, 3. platform beams, 4. top board, 5. interior coxostermum, 6. middle pectoral plate, 7. outer coxostermum, 8. special-shaped piece, 9. awning post, 10. footnote, 11. diaphragms, 12. awnings.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art understand.
As shown in the figure: a kind of bridge is built the T shape platform bridge construction of unification, comprise the platform beams 3 of bridge pier 1, awning 12, rail beam 2 and rail beam 2 both sides; The span of platform beams 3 is 32.7m, and the spacing of platform beams bridge pier is 32.7m, each platform beams 3 also comprise top board 4 and top board 4 under direction along ng a path interior coxostermum 5, middle pectoral plate 6 and outer coxostermum 7 are set; On top board 4 directly over outer coxostermum 7, be provided with awning post 9.Between outer coxostermum 7 and top board 4, be provided with special-shaped piece 8, the footnote 10 of described awning post 9 is by inserting on top board 4 in special-shaped piece 8.
Between interior coxostermum 5, middle pectoral plate 6 and outer coxostermum 7, direction along ng a path is provided with diaphragm 11, and the spacing of awning post 9 direction along ng a path on top board 4 is 10～15m.
The spacing of diaphragm is 10～15m, and thickness is 0.5～1.0m.The thickness that is provided with the outer coxostermum of special-shaped piece 87 positions is 0.6～1.8m.The thickness of special-shaped piece 8 is 1.0～1.8m.
