Abstract
The utility model belongs to the technical field of bridge structures and relates to a stiffening structure of an orthotropic plate. The stiffening structure comprises a steel bridge deck plate (1), a plurality of U-shaped stiffening ribs (2) and a steel web plate (4), wherein the U-shaped stiffening ribs (2) are symmetrically distributed on two sides of the steel web plate (4); the stiffening structure further comprises two flat steel plate stiffening ribs (3) which are symmetrically arranged the on two sides of the steel web plate (4); each flat steel plate stiffening rib (4) is located between the steel web plate (1) and the U-shaped stiffening ribs (3) on the same side as the flat steel plate stiffening rib (4). Compared with the traditional method, the stiffening structure has the benefits as follows: firstly, the stiffness of a steel bridge deck is improved so as to facilitate prolonging the service life of steel bridge deck pavement between the steel web plate and the U-shaped stiffening ribs; secondly, the fatigue resistance at the joint of the steel web plate and the steel bridge deck plate is improved; thirdly, sufficient welding space is ensured and the construction is convenient.
Description
Technical field
The utility model relates to a kind of stiffening construction of orthotropic plate, relates in particular to the stiffening construction of a kind of steel case web position orthotropic plate.
Background technology
Adopt the steel case beam of orthotropic plate all to be widely applied at home and abroad.Orthotropic plate is comprised of steel bridge deck, longitudinal stiffener and transverse stiffener, complex structure, and weld seam quantity is many, and repeatedly bears the effect of automobile wheel load, stressed comparatively unfavorable.Multiple diseases has appearred in China's part orthotropic slab case beam, and be in particular in: 1. groove is even cheated in paving steel bridge deck crack in various degree, especially near normal the appearance along bridge to the pattern cracking steel web; 2. local location weld seam or steel plate fatigue fracture, wherein the junction of steel web and steel bridge deck is often comparatively serious.According to research, mainly regional steel bridge deck strain is excessive relevant therewith for the above-mentioned disease of steel web position.In order to prevent this type of disease, considered following two kinds of methods in the design: 1. will be close to the 1st U-shaped stiffening rib of web and the spacing between the steel web and dwindle in the past; 2. part thickeies the thickness of slab of this regional steel bridge deck.Method deficiency 1. is, along with reducing of U-shaped stiffening rib and steel web clear distance, the welding space of steel web and steel bridge deck junction is also reducing, and welding quality is difficult to guarantee; Because the welding space is little, part steel work processing factory even disconnects steel bridge deck in the steel web position.Method shortcoming 2. mainly is, for fear of weld seam, concentrates, and the scope of local thickening can not be too small, cause steel using amount bigger than normal, and working procedure is many.
The utility model content
In view of the deficiency of above-mentioned hands-on approach, the purpose of this utility model is to provide a kind of stiffening construction of orthotropic plate, and the job practices of this kind of stiffening construction is provided.The utility model can reduce the strain of this regional steel bridge deck, can guarantee the welding space again, and steel using amount province, and cost is low.To achieve these goals, the technical solution adopted in the utility model is:
A kind of stiffening construction of orthotropic plate, comprise steel bridge deck (1), a plurality of U-shaped stiffening rib (2) and steel web (4), each U-shaped stiffening rib (2) is symmetrically distributed in the both sides of steel web (4), described stiffening construction also comprises two plain plate stiffening ribs (3) that are arranged symmetrically in steel web (4) both sides, and plain plate stiffening rib (3) is positioned between the U-shaped stiffening rib (2) of steel web (4) and homonymy.
As preferred embodiment, plain plate stiffening rib height is not more than 150mm.
With conventional art, compare, the beneficial effects of the utility model are:
(1) on the basis that the utility model is arranged at conventional orthogonal opposite sex plate longitudinal stiffener, increase a plain plate stiffening rib between steel web and U-shaped stiffening rib, improved the rigidity of Steel Bridge Deck, be conducive to extend the life-span of this position paving steel bridge deck;
(2) plain plate stiffening rib height is not more than 150mm, has guaranteed that there are enough welding spaces this position, constructs convenient.
The accompanying drawing explanation
The structural representation that Fig. 1 is orthotropic plate longitudinal stiffener in conventional art;
Fig. 2 is structural representation of the present utility model.
In figure:
1---steel bridge deck 2---U-shaped stiffening rib 3---plain plate stiffening rib
4---steel web 5---weld seam 6---weld seams
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
Fig. 1 is the structural representation of orthotropic plate longitudinal stiffener existing commonly used, because its U-shaped stiffening rib 2 is larger with the spacing of steel web 4, causes this position stiffness deficiency, some diseases occur.Fig. 2 is structural representation of the present utility model, and as shown in the figure: the stiffening construction that the utility model is a kind of orthotropic plate comprises steel bridge deck 1, U-shaped stiffening rib 2, plain plate stiffening rib 3 and steel web 4.U-shaped stiffening rib 2 and the common mixing stiffening construction that forms steel web 4 position steel bridge decks 1 of plain plate stiffening rib 3.
Although the above is described the utility model in conjunction with figure; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that do not break away from the utility model aim, can also make a lot of distortion, within these all belong to protection of the present utility model.
Claims (2)
1. the stiffening construction of an orthotropic plate, comprise steel bridge deck (1), a plurality of U-shaped stiffening rib (2) and steel web (4), each U-shaped stiffening rib (2) is symmetrically distributed in the both sides of steel web (4), it is characterized in that, described stiffening construction also comprises two plain plate stiffening ribs (3) that are arranged symmetrically in steel web (4) both sides, and plain plate stiffening rib (3) is positioned between the U-shaped stiffening rib (2) of steel web (4) and homonymy.
2. the stiffening construction of orthotropic plate according to claim 1, is characterized in that, plain plate stiffening rib height is not more than 150mm.
