Abstract
The utility model discloses a top and bottom plate reinforcing structure for steel box beam, and relates to a steel box beam reinforcing structure of a bridge, which comprises a panel, a horizontal separation plate vertical to the panel and a reinforcing rib vertical to the panel and vertically runs through the horizontal separation plate; the horizontal separation plate is correspondingly provided with through holes; the cross section of the reinforcing rib is U-shaped and is composed of an opening end face, a closing end face and two side faces between the both; the width of the opening end face is greater than that of the closing end face, and the opening end face is ladder-shaped and is fixed with the panel; the two side faces are fixed with the through holes of the horizontal separation plate; a gap is disposed between the closing end face and the through hole of the horizontal separation plate; and the both corners of the closing end face of the through holes are provided with a round hole respectively which are connected with the through holes, and the both corners of the opening end face are also provided with an overwelding hole respectively which are connected with the through holes. The top and bottom plate reinforcing structure for steel box beam is higher in rigidity and more difficult to deform.
Description
Technical field
The utility model relates to a kind of bridge steel box girder ruggedized construction, relates in particular to putting more energy into to top board or base plate.
Background technology
In field of bridge construction, all need counter plate (top, base plate) that stiffening rib is set usually for steel case beam and reinforce, strengthen rigidity, avoid distortion at present.Present widely used stiffening rib is that bar shaped is put more energy into, and it also vertically runs through the stripe board of diaphragm for vertical panel.This structure of putting more energy into exists following problems: 1, the assurance to the integral rigidity of steel case beam has much room for improvement; 2, bar shaped stiffening rib width is generally in 100-120 millimeter scope, behind the cutting forming distortion very big, be difficult to again proofread and correct.3, panel adopts bar shaped to put more energy into, and the bar shaped stiffening rib quantity that needs is many, spacing is little, and very serious welding deformation can take place panel when welding with panel.4, panel adopts bar shaped to put more energy into, and the diaphragm perforate is corresponding need be less, is unfavorable for that stiffening rib passes, and efficiency of construction is low.
The utility model content
The purpose of the utility model is the defective that exists to prior art, propose a kind of integral rigidity more by force, the more on-deformable steel case back base plate structure of putting more energy into.
The purpose of the utility model realizes through following technical proposals:
A kind of steel case back base plate structure of putting more energy into comprises panel, the diaphragm of vertical panel; And vertical panel and vertically run through the stiffening rib of diaphragm, correspondence is provided with through hole on the diaphragm, and said stiffening rib cross section is " U " shape; Form by open end, Closed End and two sides between the two, and the open end width is closely trapezoidal greater than the Closed End width; Its open end and panel are fixed, and two sides and diaphragm through hole are fixed, and leave the gap between Closed End and diaphragm through hole; Two jiaos of said through hole Closed End have one with the circular hole of its UNICOM, two jiaos of open end also have one with the welding hole of crossing of its UNICOM.
The effect of each part is following in the utility model:
" U " shape stiffening rib runs through diaphragm, and fixes with panel, diaphragm simultaneously, makes the three constitute a structural entity, plays good reinforcement effect.
The circular hole that Closed End is two jiaos both can solve local welding stress, and the U-shaped stiffening rib is passed through smoothly.
The welding hole excessively that open end is two jiaos helps weld seam and keeps being communicated with.
The beneficial effect of the utility model:
1, comparing bar shaped puts more energy into; " U " shape section that " U " shape is put more energy into has better structural rigidity and deformation resistance; Also increased simultaneously the fixed-area that contacts with diaphragm and panel, made the integral rigidity of steel case beam be able to strengthen: fixedly risen to two-sided contact and fix by original the contact with the single face of diaphragm; Fixedly rose to two-wire and contact and fix by original the contact with the single line of panel.
2, anti-cutting deformability is higher: " U " shape stiffening rib spreading width promptly uses the justifying cutting generally in 650 millimeter, is out of shape also little.
3, anti-welding deformation ability is higher: panel adopts " U " shape stiffening rib, and the stiffening rib quantity that needs is few, spacing is big, welding deformation can not take place when welding with panel; And the setting of two jiaos of circular holes of Closed End, further solve local welding stress.
4, efficiency of construction is higher: panel adopts " U " shape to put more energy into, and the diaphragm through hole is bigger, and the setting of two jiaos of circular holes of Closed End, helps passing of longitudinal direction stiffening rib, and speed of application is improved.
5, leave the gap between " U " shape stiffening rib Closed End and diaphragm through hole, simply but the utmost point has avoided here the most incidental stress to concentrate effectively.
Description of drawings
Fig. 1 is the cross-sectional configuration sketch map of the utility model;
Fig. 2 is the partial enlarged drawing of X part among Fig. 1.
Among the figure, 1 is top board, and 2 is base plate, and 3 is back, and 4 is diaphragm, and 5 is stiffening rib, and 6 is through hole, and 7 is circular hole, and 8 was welding hole.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, a kind of steel case back base plate structure of putting more energy into comprises panel; The diaphragm 4 of vertical panel, and vertical panel and vertically run through the stiffening rib 5 of diaphragm 4, correspondence is provided with through hole 6 on the diaphragm 4; This panel both can be the top board 1 of steel case beam, also can be base plate 2, and said stiffening rib 5 cross sections are " U " shape; Form by open end 9, Closed End 10 and two sides 11 between the two, and open end 9 width are closely trapezoidal greater than Closed End 10 width; Its open end 9 is fixed with panel, and two sides 11 are fixing with diaphragm 4 through holes 6, and Closed End 10 and 6 of diaphragm 4 through holes leave the gap; Stiffening rib 5 cross sections can also be " V " shape and " Y " shape, and it all has similar U-shaped structure, therefore have similar method for using and effect.Two jiaos of said through hole 6 Closed Ends 10 have one with the circular hole 7 of its UNICOM, two jiaos of open end 9 also have one with its UNICOM cross welding hole 8.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
