Abstract
The utility model relates to a connection structure of orthotropic steel bridge deck board, the orthotropic steel bridge deck board is the steel bridge panel system that comprises roof, cross slab and vertical stiffening rib, sets up the arc breach in cross slab and roof and stiffening rib junction, sets up the circumferential notch in cross slab and stiffening rib bottom junction to with vertical stiffening rib and cross slab and roof welded connection, thereby connect into a whole with roof, cross slab, vertical stiffening rib. Through the breach of seting up the definite shape on the cross slab, make vertical stiffening rib pass through, reduced the stress concentration phenomenon of decking, cross slab, vertical stiffening rib junction, improved the atress performance of connecting details department, improved the life of bridge. And the utility model discloses a connection structure safe and reliable, the construction installation is simple, convenient.
Description
Technical field
The utility model relates to a kind of syndeton of Orthotropic Steel Bridge Deck, belongs to technical field of bridge engineering.
Background technology
Orthotropic plate is since coming out after World War II, and because of from heavy and light, ultimate bearing capacity is large, highly low, is easy to processing and manufacturing, the advantages such as short construction period, is widely used in big or middle span bridge by European, Japan and other countries.At the end of last century, along with the continuous maturation of orthotropic plate theory and the raising of construction technology, the countries such as the U.S. also start more and more to apply orthotropic plate.Since the eighties in 20th century, orthotropic plate obtains in China and develops rapidly, and particularly the construction of China's numerous large span Yangtze Bridge in recent years facilitates development and the application of orthotropic steel bridge deck especially.The accumulated damage that bridge floor causes under various vehicular load repeated action; Steel bridge deck is due to the local action directly by vehicle vehicle simultaneously, and Stress influence line is short, and a car crosses and can cause Cyclic Stress for several times, and add that the stress of welding node is concentrated and unavoidable weld defect, steel bridge deck is easy to fatigue cracking.
Diaphragm is one of important component part of Orthotropic Steel Bridge Deck, and tapping (breach) the stress concentration phenomenon that crossbeam (diaphragm) web allows vertical rib pass through is comparatively obvious, therefore nicked form is very big for the stress distribution impact of diaphragm, and dissimilar nicked form obviously can change its stress state.
Summary of the invention
The purpose of this utility model is to provide the syndeton of Orthotropic Steel Bridge Deck diaphragm and longitudinal stiffener in a kind of bridge engineering, improve the stress performance of steel bridge deck, reduce the stress concentration phenomenon of bridge deck, diaphragm, longitudinal stiffener junction, the technical problem that the stress solving top board, diaphragm and the longitudinal stiffener junction welding node existed in prior art is concentrated.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A syndeton for Orthotropic Steel Bridge Deck, described Orthotropic Steel Bridge Deck comprises top board 1, diaphragm 2 and longitudinal stiffener 3, is vertical connection between top board 1 and diaphragm 2; Longitudinal stiffener 3 is by two sides 31 tilted and the inverted trapezoidal structure that forms of bottom surface 32, and the opening direction of this inverted trapezoidal structure towards the bottom surface of top board 1, and is embedded in diaphragm 2, and its surfaces externally and internally is all connected with diaphragm 2; The axis direction of longitudinal stiffener 3 is perpendicular to the surface of diaphragm 2, its part is positioned at the right angle of the formation of top board 1 and diaphragm 2, the top edge of this surface 31 is connected to the bottom surface of top board 1, and the remainder of longitudinal stiffener 3 exposes outside diaphragm 2 through diaphragm 2; The junction of the side 31 of diaphragm 2 and top board 1 and longitudinal stiffener 3 offers arc notch 4, and diaphragm 2 offers circumferential notch 5 with the junction of the bottom surface 32 of longitudinal stiffener 3.
Preferably, the bottom surface 32 of described longitudinal stiffener 3 be arranged in parallel with top board 1.
Preferably, the connection between the top edge of the side 31 of described longitudinal stiffener 3 and top board 1 is for being welded to connect, and the connection between the surfaces externally and internally of longitudinal stiffener 3 and diaphragm 2 is also for being welded to connect.
Preferably, described arc notch 4 is 1/4 circular arc, and described circumferential notch 5 is 3/4 circular arc, and concrete arc radius specifically according to Practical Project situation and stressedly need to be determined.
Preferably, the side 31 of described longitudinal stiffener 3 is set to lead angle with the junction of bottom surface 32 and is connected.
The beneficial effects of the utility model are: diaphragm is welded in below top board, add the longitudinal rigidity of top board; Longitudinal stiffener is longitudinally connected with top board, is welded in the below of top board, adds the lateral stiffness of top board; Diaphragm offers the breach of definite shape, and longitudinal stiffener is passed through, and reduces the stress concentration phenomenon of bridge deck, diaphragm, longitudinal stiffener junction, improves joint detail place stress performance, improves the application life of bridge; And this syndeton is safe and reliable, construction and installation are simple, convenient.Described top board is Orthotropic Steel Bridge Deck top board, and its thickness meets minimum requirement that is stressed and regulation and stipulation.
