Abstract
The utility model relates to a cantilever box girder structure with a brace rod, which is characterized in that at least one group of sway rods are arranged between a cantilever and a web. When in use, the cantilever box girder structure with the brace rod of the utility model is provided with a steel stray rod between a traditional long cantilever box girder and the web, wherein the stray rod commonly adopts the circular cross section, and has 0.2-0.4m diameter and 10mm-16mm wall thickness. And the design changes the double cantilever mode of the transverse forcing of a box girder top board into four-point support mode, thereby effectively reducing the transverse internal force of the box girder top board, and increasing the transverse rigidity of a box girder.
Description
Technical field:
The utility model relates to the technical field of civil engineering bridge design, specifically a kind ofly chooses the arm box-beam structure with strut.
Background technology:
In highway and the design of urban road bridge, having the box-beam structure of choosing arm greatly is the superstructure form that often adopts, this form of structure can effectively must reduce the superstructure scale of construction, and the mutually deserved substructure scale of construction that reduces, minimizing takies soil and space, make beam body landscape effect more very thin, have more dynamics U.S. of structure.And owing to choose the existence of arm greatly, the beam body side surface can be avoided the sunlight direct projection substantially, can reduce the influence that the temperature difference produces for structural internal force.
But if it is excessive or to choose the arm portion load heavier to choose arm, in order to satisfy stressed needs, choose the arm roots structure height and need strengthen or adopt ribbed structure, these two kinds of design forms have all increased the structure scale of construction and deadweight, and bridge view and economy all can be affected.
Summary of the invention:
What the purpose of this utility model was to provide a kind of improved band strut chooses the arm box-beam structure, and the design form that it can overcome outrigger in the prior art has all increased the some shortcomings of the structure scale of construction and deadweight.
To achieve these goals, the technical solution of the utility model is: a kind ofly choose the arm box-beam structure with strut, it mainly comprise choose arm with choose the web that arm links to each other, choose between arm and the web and to form the case beam, it is characterized in that: choose and be provided with at least one group of hound between arm and the web.
During use band strut of the present utility model choose the arm box-beam structure, choose arm case beam greatly in tradition and choose the steel work hound is set between arm and the web, hound generally adopts circular cross-section, diameter 0.2～0.4m, wall thickness 10mm～16mm.This design makes that case back plate is lateral stressed to change 4 support modes into by two cantilever mode, effectively must reduce the horizontal internal force of case back plate, has increased case beam lateral stiffness.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the lateral view of Fig. 1
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprise choose arm 1 with choose the web 2 that arm links to each other, choose between arm and the web and to form the case beam, it is characterized in that: choose and be provided with at least one group of hound 3 between arm and the web.Be provided with diaphragm in the case beam, the position of hound is corresponding with the position of diaphragm.Hound is a steel work, and its cross section is circular, and the diameter of hound is 0.2-0.4m, and the wall thickness of hound is 10-16mm.The distance of tie point between hound and the web and web bottom is 0.3～0.5m, and hound and the tie point of choosing between the arm are 0.2-0.4m with the distance of choosing the arm edge.
In force, hound is a steel work, and its cross section is circular, and the diameter of hound is 0.4m, and the wall thickness of hound is 15mm.The intersection point that hound and case beam are chosen arm should be noted and choose the arm edge and leave 0.2m, avoid conflicting with railing or crashproof railing relative configurations; The intersection point of hound and case web should be tried one's best near case beam base plate, and the distance of tie point between hound and the web and web bottom is 0.3m, avoids producing in the case web extra internal force; If in the case beam diaphragm is set, the hound position should be corresponding with the diaphragm position, if no diaphragm in the case beam, then the hound spacing is determined than choosing by the multi-scheme of considering factors such as strut size, spacing; Hound can be constructed simultaneously with case beam agent structure and be finished, and also can implement according to the load deployment scenarios is at a specified future date, and the joint construction that only need implement to choose with the case beam arm and web in the recent period gets final product; The steel work hound scale of construction is less, and permeability is better, can not have a negative impact to the box girder integral view, and will increase the Beauty of Rhythm of structure according to the oblique strut of certain pitch arrangement.
The arm box-beam structure of choosing of this band hound provides a new thinking for the transverse design of choosing arm case beam greatly, and is big or choose the arm load and have general directive significance than the design of loaded van girder construction to similarly choosing arm from now on.
