Abstract
The utility model discloses a T-shaped stiffening rib steel box girder structure which is composed of a top plate, a bottom plate, a left web, a right web and diaphragm plates in a mutually welded mode, wherein the diaphragm plates are arranged between the top plate, the bottom plate and the two webs. The top plate and the bottom plate are respectively provided with a plurality of T-shaped stiffening ribs arranged at intervals. T-shaped stiffening rib passing holes allowing the T-shaped stiffening ribs to penetrate are correspondingly formed in the upper edge of each diaphragm plate and the lower edge of each diaphragm plate. A connecting lug is arranged at the closed end of each T-shaped stiffening rib passing hole and fixed to a wing plate of each T-shaped stiffening rib in a welded mode. According to the T-shaped stiffening rib steel box girder structure, the T-shaped stiffening ribs are directly welded to each diaphragm plate, so that the strength of a steel box girder is guaranteed, the use amount of steel is greatly reduced, the production cost is saved, the welding amount is reduced, the welding difficulty is lowered, and the welding quality is guaranteed.
Description
Technical field
The utility model relates to steel structure bridge technical field, more particularly, relates in particular to a kind of T shape stiffening rib steel box girder.
Background technology
T shape stiffening rib be the most common in steel structure bridge, be also one of of paramount importance building block.For guaranteeing bridge intensity, T shape stiffening rib is generally designed to continuously, uninterrupted form, therefore on the diaphragm 1 of steel case beam, offer the excessive hole 2 of T rib, as depicted in figs. 1 and 2, being connected between T shape stiffening rib 3 and diaphragm 1, traditional design is to adopt the stiffening plate 4 of two rectangles to weld respectively diaphragm 1 to strengthen with T shape stiffening rib 3.Adopt stiffening plate to connect T shape stiffening rib and diaphragm, the number of spare parts of its use is many, and rolled steel dosage is large, and welding capacity is large, and Welder's potential difference, and difficulty is high, and welding quality is difficult to guarantee.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of T shape stiffening rib steel box girder is provided, and this steel box girder intensity is high, rolled steel dosage is few, and welding capacity is little and difficulty is low, and welding quality is guaranteed.
For achieving the above object, T shape stiffening rib steel box girder provided by the utility model, by the web of top board, base plate, the left and right sides and be arranged on diaphragm between top board, base plate and two webs and be welded to each other and form, on described top board and base plate, be provided with the T shape stiffening rib at some intervals, the upper and lower edge correspondence of diaphragm offers the excessive hole of T rib that can pass through for T shape stiffening rib, described diaphragm is provided with attachment lug on the blind end in the excessive hole of T rib, and the wing plate of this attachment lug and T shape stiffening rib is welded and fixed.
The utility model compared with prior art, saved the use of stiffening plate, but on the blind end in the excessive hole of T rib of steel case beam diaphragm, attachment lug is set, and the wing plate of attachment lug and T shape stiffening rib is welded and fixed, T shape stiffening rib and diaphragm are directly welded together, when guaranteeing steel case beam strength, greatly reduced the consumption of steel, saved cost of production, reduced welding capacity and reduced welding difficulty, made welding quality more guaranteed.
