Description
Technical field
The utility model relates to a kind of rod member and strengthens structure, has been specifically related to a kind of steel bridge frame member and has strengthened structure, be mainly used in mountable steel bridge.
Background technology
In recent years, along with city and economic fast development, China's urban road bridges facility development is very fast, especially steel structure bridge.Steel bridge deck directly bears wheel-borne load effect as bridge deck, it is jointly stressed that steel bridge deck also participates in girder as a girder part, this just makes steel bridge deck easily produce fatigue failure, for because of pressurized, the component and the steel bridge deck that there is pressure zone by curved and being cut etc., if design unreasonable, the stressed weakness of rod member, may make steel work occur overall collapse or local buckling, architecture lost resistivity is made after unstability, so that overall slump.Therefore the utility model provides a kind of steel bridge frame member reinforcement structure, by arranging φ 273 seamless steel pipe and stiffener in general frame rod member junction, alleviate steel bridge overall weight, reinforced frame rod member bonding strength, strengthen the stress performance of stressed node region, ensure the resistance to overturning of steel bridge framework, increase steel bridge service life.
Utility model content
The purpose of this utility model there are provided a kind of steel bridge frame member and strengthens structure, by arranging φ 273 seamless steel pipe and stiffener in general frame rod member junction, alleviate steel bridge overall weight, reinforced frame rod member bonding strength, strengthens the stress performance of stressed node region.
The utility model is achieved by the following technical solution: a kind of steel bridge frame member strengthens structure, comprises steel pipe, the first rod member, stiffener, the second rod member; Framework integral outer structure is in square, and interior diagonal is connected in X font; 4 piece of first rod member interval equal angular is assembled in by being welded to connect outside steel pipe, welded steel pipe outside 4 piece of first rod member, welds 4 piece of second rod member, insert stiffener and be welded to connect between adjacent rod member between the adjacent steel pipe in outside.
Be provided with stiffener between described adjacent two pieces of rod members, stiffener length is identical with adjacent rod member fusion length, and stiffener height is identical with steel pipe height.
Described steel pipe adopts φ 273 seamless steel pipe to make.
The first described rod member and the second rod member all adopt Q345BH shaped steel to make.
The beneficial effects of the utility model are: by arranging φ 273 seamless steel pipe and stiffener in general frame rod member junction, alleviate steel bridge overall weight, reinforced frame rod member bonding strength, strengthen the stress performance of stressed node region, ensure the resistance to overturning of steel bridge framework, increase steel bridge service life.

Reference numeral: 1 is steel pipe, 2 is the first rod member, and 3 is stiffener, and 4 is the second rod member.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail.But embodiment of the present utility model is not limited to this.
As shown in fig. 1, a kind of steel bridge frame member strengthens structure, comprises steel pipe 1, first rod member 2, stiffener 3, second rod member 4; Framework integral outer structure is in square, and interior diagonal is connected in X font; 4 piece of first rod member 2 interval equal angular is assembled in by being welded to connect outside steel pipe 1, and welded steel pipe 1 outside the first rod member 2 welds the second rod member 4 between the adjacent steel pipe 1 in outside, inserts stiffener 3 and be welded to connect between adjacent rod member.Stiffener 3 length is identical with adjacent rod member fusion length, and stiffener 3 height is highly identical with steel pipe 1; Steel pipe 1 adopts φ 273 seamless steel pipe to make, and the first rod member 2 and the second rod member 4 all adopt Q345BH shaped steel to make.
At workbench, 4 piece of first rod member 2 is reserved certain weld width, the identical angle in interval is assembled in outside steel pipe 1, assembled complete after, utilize CO
2gas shield is welded in 4 piece of first rod member 2 and center, steel pipe 1 junction and carries out spot welding and fix; After spot welding is fixing, carry out welded corner joint, complete being welded to connect of the first rod member 2 and center steel pipe 1; Then between adjacent first rod member 2, stiffener 3 is inserted in commissure, to welded corner joint, strengthens the first rod member 2 junction stress-bearing capability; Diagonal angle welded steel pipe 1 outside the first rod member 2, allowance weld carries out assembled between outside steel pipe 1 of the second rod member 4, assembled complete after, utilize CO
2gas shielded arc welding in this connection heart place carries out spot welding and fixes; stiffener 3 is inserted the solder design place that adjacent rod member is reserved, successively to welded corner joint, less welding deformation; ensure the first rod member 2 and the second rod member 4 bonding strength; framework overall structure, as Fig. 3, adopts said frame rod member to strengthen structure, not only alleviates steel bridge deadweight; and strengthen the stress performance of stressed node region; reinforced frame rod member bonding strength, ensures the resistance to overturning of steel bridge framework, increases steel bridge service life.
