Description
Technical field
The utility model relates to traffic engineering field, specifically be applied to a kind of T-shaped connector in steel structure bridge.
Background technology
At present, steel work obtains universal and sustainable development in China, and steel work has been widely applied to the aspect such as railroad bridge, highway bridge.Comparatively concrete structure has from heavy and light steel work, intensity is high, anti-seismic performance good, be convenient to the features such as suitability for industrialized production again, the building structure being also energy-conserving and environment-protective, can recycling simultaneously.Along with the enforcement of nation-building conservation-minded society strategic decision, development housing and public buildings that use less energy and land are more and more subject to central and local governments and pay attention to, a large amount of steel work has all been built across river, bridge spanning the sea and the engineering such as highway, railway bridge in the ground such as Beijing, Shanghai, Guangdong, Zhejiang, Jiangsu, embodies steel structure bridge good momentum of growth.
T-shaped connector is widely used in steel work as a kind of important component, and this connector is specially adapted in the semirigid frame in highlight lines area.At present, the rectangle edge of a wing T-connecting piece of Type of Welding is applied in structural engineering more at home and abroad, but existing rectangle edge of a wing T-connecting piece but also exists some defects.On the one hand, in this T-connecting piece, welding capacity is comparatively large, and web and frange plate connecting portion exist more serious residual stress and permanent set.In theory, residual stress can not affect to some extent on the static(al) supporting capacity of component, but the existence of residual stress will have influence on component fatigue performance, ductility and stability etc. greatly; And the existence of permanent set will have influence on the specious degree of component, also the mechanical property of component will be weakened simultaneously.So, when making this kind of T-connecting piece, need higher welding procedure and aftertreatment technology, minimizing residual stress and permanent set are on the impact of element mechanics performance as far as possible, on the other hand, in domestic and international project, the energy-dissipating property of T-connecting piece is paid little attention to, existing T-connecting piece stock utilization is extremely low, energy dissipation capacity is poor, , domestic and international correlative study shows, under the T-connecting piece geological process of the rectangle edge of a wing, the frange plate of T-connecting piece can form plastic hinge because sub-fraction regional stress concentrates, and bolt there will be larger stress concentrate, and now the material of other part of T-connecting piece is also in elastic stage.The mode of failure of existing T-connecting piece is generally: occur drawing crack crack in commissure, the edge of a wing, and extend along width and thickness, until rupture completely, now rectangle T-connecting piece bearing capacity completely loses, reduce the safety factor of node area, and then bring potential safety hazard to bridge construction.
In sum, in building structure, existing rectangle T-connecting piece is adopted will to face following problem: 1. weld seam ductility is poor, and corrosion problem easily appears in position while welding; 2. welding process requirement is high, loaded down with trivial details; 3. the residual stress of welding and permanent set greatly, easily produce installation deviation; 4. the problem of the energy-dissipating property difference of connector; Durability, the mechanical property of 5.T shape connector are poor; 6. stock utilization problem.These problems above-mentioned all will affect the structural performance of steel work under all kinds of operating mode significantly, and design margin evaluation is lower.
Summary of the invention
In order to the deficiency that the weld seam ductility overcoming existing rectangle T-connecting piece is poor, welding process requirement is high, durability, mechanical property are poor, stock utilization is lower, design margin evaluation is lower, the utility model provides two L shape combination type T types power consumption connectors that a kind of weld seam ductility is better, welding procedure is low, durability, mechanical property better, stock utilization is higher, design margin evaluation is higher.
