Description
Technical field：
The invention belongs to steel structure bridge technical fields, and in particular to the no-welding ruggedized construction of steel box-girder side plate and reinforcing side
Method.
Background technique：
With the development of Chinese national economy, the volume of traffic is continuously increased, and vehicle develops to heavy-duty, Longspan Bridge construction
Increase year by year, closing steel box-girder is widely used in medium-and-large-sized bridge construction.Steel box-girder is closed generally by top plate, side plate and U rib
It is formed by connecting by welding, and key position of the U rib as load-bearing, structure quality of connection is required very high.
On the one hand the heat generated during steel box-girder welding can generate adverse effect to steel box girder.Another party
Face steel box-girder is influenced due to action of rust in the long-term use, U rib lower end and the side plate junction strength of materials can be lower and
It deforms, to generate security risk.
Summary of the invention：
The purpose of the invention is to overcome the deficiencies in the prior art, and provide a kind of structurally reasonable, easily manufactured, reinforcing
The good steel box-girder side plate reinforcing construction of effect.
Embodiments of the present invention are：A kind of steel box-girder assembling type node reinforcing construction, it includes U rib, on the U rib
End is connected with top plate, and the U rib and top plate vertical welding are on side plate.The U rib lower end and side plate add list by angle steel
Side bolt is reinforced, and angle steel is attached by bolt A with side plate, is attached by bolt B and U rib lower end.
The connection type of the U rib and top plate and side plate is welding.
Described bolt A, the B is unilateral bolt and is connected with nut and gasket.
The steel box-girder is the closing box beam of U-shaped box beam, triangle box beam, rectangular box beam or arbitrary section.
One side of the angle steel is attached reinforcing by bolt A and side plate.
Another side of the angle steel is attached reinforcing by bolt B and U rib lower end.
Beneficial effects of the present invention：
U rib lower end and side plate are reinforced by the angle steel and bolt, U rib is avoided with lateral plate structure and corrodes thinning cause
The case where structural behaviour reduces；Angle steel and bolt combination can be influenced in bridge by crosswind load and earthquake etc. due to its architectural characteristic
When dissipation bridge vibrational energy；The angle steel adds the combination of bolt to be conveniently replaceable, when irreversible transformation and fracture occur for angle steel
New angle steel can be dismantled and then replaced with to original structure when destruction；To sum up, the present invention has structurally reasonable, easily manufactured, replacement
Advantage easy, consolidation effect is good.

Specific implementation method：
Following further describes the present invention with reference to the drawings.
Embodiment 1：
As shown in Figure 1 to Figure 3, a kind of steel box-girder assembling type node reinforcing construction, it includes side plate 1, the side plate 1
There is a U rib 2 in front end, and there are a top plate 3 in the side plate 1 and 2 upper end of U rib, the side plate 1, U rib 2 and top plate 3 all by be welded to connect at
To close steel box-girder.
The unilateral bolt is made of screw rod 7, nut 8, washer 9, sleeve 10, split type washer 11 and nut 12, at angle
Screw hole 13 and screw hole 16 are opened on steel, screw hole 14 is opened on side plate, are provided with screw hole 15 in U rib.
The U rib 3 is connect by bolt 5 with angle steel 4；The side plate 1 is connect by bolt 6 with angle steel 4；The side plate 1
It is reinforced and is connected by angle steel 4, bolt 5 and bolt 6 with U rib 3.
The contact surface of angle steel and steel box-girder needs to do frosted processing, so that contact surface coefficient of friction meets design requirement.
Specific construction scheme：
1) angle steel is suitably positioned, specific requirement is that one side is bonded with U rib lower end on the outside of angle steel, outside other one
Face is bonded with side plate；
2) rib aperture 15 is determined by 13 position of angle steel aperture, rib aperture 14 is determined by 16 position of angle steel aperture；
3) the angle steel aperture 13 is positioned with U rib aperture 15 by bolt 5 it is just stubborn, by bolt 6 by the angle
Steel aperture 16 and side plate aperture 14 are twisted at the beginning of being positioned；
4) realize that be located by connecting and then carry out bolt twists eventually, realizes and applies bolt pretightening.
The present invention implement when, the side plate 1, the closing steel box-girder that U rib 2 and top plate 3 are welded into normal operating range it
There is the reinforcing combined member being made of the combination of angle steel 4, bolt 5 and bolt 6 to be reinforced outside.The reinforcing combined member can be
Side plate 1 and U rib 2 occur to play the role of thickening component when corrosion is thinning, while a part of vibrational energy can be absorbed.Except this
Except angle steel when irreversible transformation occurs and destroying, that is, replaceable new angle steel.
This hair can be understood and applied the above description of the embodiments is intended to facilitate those skilled in the art
It is bright.Person skilled in the art obviously easily can make various modifications to these embodiments, and described herein
General Principle is applied in other embodiments without having to go through creative labor.Therefore, the present invention is not limited to implementations here
