Abstract
The utility model provides a highway with stride a formula single track and build the bilateral case section of bridge jointly and construct to reach mesh rational in infrastructure, that the investment economizes. It includes that horizontal bridge establishes left side steel case roof beam, right side steel case roof beam to the interval to and indulge the crossbeam that the bridge set up to the interval, left side steel case roof beam, right side steel case roof beam and crossbeam concrete as an organic wholely, stride a formula single track and set up on the crossbeam between left side steel case roof beam, right side steel case roof beam.
Description
Technical field
The utility model relates to bridge, and particularly a kind of highway and straddle-type monorail build the bilateral case cross-section structure of bridge jointly.
Background technology
In recent years, the construction of domestic city track traffic and municipal administration/highway engineering is in the ascendant, on urban river and large river basin and even sea-crossing engineering, all needs to build highway bridge or rail traffic bridge.And highway and track traffic build jointly must bring save bridge location resource, jointly stressed, increase the number of advantages such as the rigidity of structure, in general, highway and rail traffic building jointly can save total construction investment, and therefore increasing highway and rail traffic building jointly bridge emerges.And straddle-type monorail itself has the plurality of advantages such as land used is little, climbing capacity is large have also been obtained and promote the use of, traditional Straddle type monorail and highway bridge Round Sump, generally directly be arranged on highway bridge, and fail effectively to reduce the engineering quantity of bridge deck structure, the present invention is intended to a kind of novel highway of research and straddle-type monorail with laminated New type section form of building, to reach rational in infrastructure, the object of reduced investment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of highway and straddle-type monorail builds bridge bilateral case section structure jointly, to reach rational in infrastructure, the object of reduced investment.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of highway of the present utility model and straddle-type monorail build the bilateral case cross-section structure of bridge jointly, it is characterized in that: it comprises direction across bridge interval and establishes left side steel box-girder, right side steel box-girder, and vertical bridge is to spaced crossbeam, left side steel box-girder, right side steel box-girder and crossbeam consolidation are integrated, straddle-type monorail is arranged on the crossbeam between left side steel box-girder, right side steel box-girder, and by beam supporting.
The beneficial effects of the utility model are, take full advantage of the carrying span of straddle-type monorail, have farthest played structure tension performance; Straddle-type monorail part does not establish bridge floor, reduces the top area of beam body, decreases bridge engineering quantity; Adopt horizontal beam of lifting to connect two case, both enhance connection and the globality of two panels case beam, also as effective support of straddle-type monorail; Bilateral box structure, substantially reduces the scale of construction of case beam, the execution conditions that the case beam for different structure form is all provided convenience; Bridge is built jointly for highway and straddle-type monorail there is good compliance and referentiability.
Accompanying drawing explanation
This manual comprises following two width accompanying drawings:
Fig. 1 is traditional form of fracture schematic diagram that existing highway and straddle-type monorail build bridge jointly;
Fig. 2 is that a kind of highway of the utility model and straddle-type monorail build the profile of the bilateral case cross-section structure of bridge in crossbeam position jointly.
Component shown in figure and corresponding mark: left side steel box-girder 21, right side steel box-girder 22, crossbeam 23, straddle-type monorail 20.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is traditional form of fracture schematic diagram that existing highway and straddle-type monorail build bridge jointly, this cross-section structure may go out different beam type according to the different manifestations of bridge deck width, such as case beam, choose greatly arm case beam, juxtaposition small box girder etc., the most essential feature of traditional form of fracture is bridge floor itself is full paving continuous print, straddle-type monorail is arranged on continuous print bridge floor, and straddle-type monorail track structure itself is track structure is the bridge construction possessing weight capacity, deck system except track fulcrum there is no demand functionally, only as bridge maintenance platform, adopt traditional Bridge Sections, bridge floor completely spreads, correspondingly waste bridge deck works quantity.
Fig. 2 is that a kind of highway of the utility model and straddle-type monorail build the profile of the bilateral case cross-section structure of bridge in crossbeam position jointly, constructively comprise direction across bridge interval and establish left side steel box-girder 21, right side steel box-girder 22, and vertical bridge horizontally lifts beam 23 to spaced, left side steel box-girder 21, right side steel box-girder 22 are integrated with crossbeam 23 consolidation.Straddle-type monorail 20 is arranged between left side steel box-girder 21 and right side steel box-girder 22, and is supported by crossbeam 23.This form of fracture is the form of fracture of bilateral case, an independently box section (left side steel box-girder 21, right side steel box-girder 22) is respectively set respectively about highway bridge part, and as main longitudinal load-bearing structure, larger span can be set to according to bridge general arrangement; Mid portion arranges straddle-type monorail, and according to the situation of the current straddle-type monorail of successful operation, being track structure in conjunction with Straddle type monorail itself, is again the feature of bridge construction, and its maximum span is 25m.Bilateral case girder can be 50m, 60m, 70m even 100m, 200m or larger according to the different spans of bridge type.Between straddle-type monorail is supported on two case beams on crossbeam, crossbeam spacing is maximum is no more than 25m (maximum span of straddle-type monorail), except straddle-type monorail fulcrum, need not arrange crossbeam between bilateral case.In view of bilateral case exists larger torsion and distortion distortion, concrete edge case easily produces crack, and in web, outside is uneven, and case beam generally selects steel box structure form.
The above just explain through diagrams a kind of highway of the utility model and straddle-type monorail build some principles of the bilateral case cross-section structure of bridge jointly, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
