Description
Technical field
The invention belongs to road and bridge fields, more particularly to a kind of steel construction honeycomb web box girder.
Background technique
With the fast development of Development of China's Urbanization, China is transformed existing urban bridge at many urban municipal construction,
To meet the growth requirement of urban highway traffic.With the popularization that highway in China is built, the bridge of various large span large-tonnages
Girder construction is also applied and is given birth to.Currently, the freely-supported bridge compared with large span mostly uses T section beam or box-girder.Because of T beam group
At T beam bridge lateral stiffness it is smaller, anti-twisting property is poor, and install when stability it is poor, be not suitable for compared with large span when use.
Simply supported girder bridge compared with large span generally uses box beam.When span is larger, the weight of concrete box girder is very big, to pouring or set up
Bring difficulty.Compound section steel box girder is composed of the steel case and the concrete slab on top flange plate of lower part, passes through shearing resistance
Connector is connected.The feature that concrete anti-compression ability is strong and steel tensile capacity is high is utilized, takes full advantage of material property.
The anti-twisting property of steel box-girder is strong, and erection construction is easy, and is suitably applied highway and Urban Bridge.With China's steel and iron industry and steel
The fast development of structure technology, the quantity of steel structure bridge are also being continuously increased, steel box girder span is big, service life is long,
The characteristics of box section torsional rigidity is big, depth of section is small, good integrity sets steel box girder in municipal administration and highway bridge
It is widely used in meter and building course, has become the first choice of large-span girder form.In science of bridge building field, it is
Meet use function and bearing capacity requirement, steel box-girder using more and more extensive.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of steel construction honeycomb web box girders, primarily to exploitation one
Kind structure is simple, and bearing capacity is big, excellent in mechanical performance, and construction efficiency is high, integrates the high steel construction honeycomb web box girder of chemical conversion degree,
With good practicability, product has substantive distinguishing features and the marked improvement of protrusion compared to existing technologies.
The technical solution adopted by the invention is as follows:
A kind of steel construction honeycomb web box girder, comprising: internal box, outer case, outer fin, inner groovy, honeycomb web, bolt hole
Hole, trapezoidal rubber voussoir, trapezoidal groove are equipped with outer fin between the internal box and outer case of box beam side, another in box beam
It is equipped with inner groovy between the internal box and outer case of side, plugs together connection between outer fin and inner groovy mutually；The top of outer fin
Be equipped with trapezoidal rubber voussoir with lower section, be equipped with trapezoidal groove above and below inner groovy, trapezoidal rubber voussoir with it is trapezoidal
Connection is mutually plugged together between groove；Installing honeycomb web inside the internal box additional, honeycomb web is equipped with several honeycomb holes,
Two neighboring box beam passes through the bolt hole connection on honeycomb web.
Further, the outer fin stretches out the half that the length of box beam is the depth that inner groovy is recessed box beam, outside
Fin with a thickness of 1st/1st to six/5th of box beam height.
Further, the inward flange overall size of the outer fin and the external periphery outline size of internal box are consistent, evagination
The external periphery outline size of rib and the inward flange overall size of outer case are consistent.
Further, the inner groovy inward flange overall size is consistent with the external periphery outline size of internal box, inner groovy
External periphery outline size it is consistent with the inward flange overall size of outer case.
Further, the honeycomb web external periphery outline size is consistent with internal box inward flange size.
Further, the area of the honeycomb hole on the honeycomb web accounts for the 70% ~ 80% of the honeycomb web gross area, and phase
Adjacent two honeycomb hole minimum spacings are 1st/1st to five/10th of box beam height.
Further, honeycomb web installation number in single box beam is 2 ~ 4.
Further, the trapezoidal longer bottom edge of rubber voussoir is flushed with the upper and lower edge of outer case respectively；It is trapezoidal recessed
The longer bottom edge of slot is flushed with the upper and lower edge of outer case respectively.
Further, the length of the trapezoidal rubber voussoir is the half of outer fin length to one third.
Further, sandblasting, dabbing or indentation processing are done in the surface of the outer fin and inner groovy, increase between box beam
Coefficient of friction.
The beneficial effects of the present invention are: box beam is divided into inside and outside cabinet, inside, sliceable evagination is had between outer case
Rib and inner groovy quickly can be positioned and be installed；In the inner box install additional have honeycomb hole web, can be provided for box beam compared with
Big bearing capacity；Meanwhile trapezoidal rubber voussoir is had in box beam upper and lower ends, it, can when box beam generates temperature stress or vibration
By squeezing the energy consumption of rubber voussoir；The configuration of the present invention is simple, bearing capacity is big, excellent in mechanical performance, and construction efficiency is high, integrates chemical conversion
Degree is high, has good practicability.
