Abstract
The invention discloses a steel box beam with the high bending resistance, torsion resistance and distortion resistance. The steel box beam comprises a box steel frame comprising an upper flange plate, a right web plate, a lower flange plate and a left web plate which are connected end to end, wherein horizontal stiffening rib plates of the two flange plates and horizontal stiffening rib plates of the two web plates are vertically crossed at the same position to form rectangular strengthening structures; the strengthening structures are fixedly installed in the box steel frame, and are distributed along the span direction of the box steel frame at intervals; longitudinal strengthening rib plates of the flange plates are respectively fixedly arranged on the upper flange plate and the lower flange plate, and are fixedly connected with the crossed parts of the strengthening structures; longitudinal strengthening rib plates of the web plates are fixedly arranged on the right web plate and the left web plate respectively, and are fixedly connected with the crossed parts of the strengthening structures. The steel box beam is simple in structure, and is capable of effectively improving the bending resistance, torsion resistance and distortion resistance.
Description
Technical field
The present invention relates to a kind of box beam, more particularly, relate to a kind of bending resistance, steel plate box ellbeam that antitorque and anti-distortion ability is strong.
Background technology
Steel plate box beam with T font has following characteristics compared with general steel plate box beam: 1, lightweight, material is economized, because box beam adopts orthotropic plate face, beam rib and top, base plate is made with steel sheet, the supporting capacity of the more effective performance steel of energy, can saving steel about 20% compared with the general steel plate box beam of same span, and span is more saved more greatly; 2, greatly, this is determined by the characteristic in closed thin wall cross section itself for bending resistance and torsional rigidity; During uniform section, section form of remaining silent can provide larger bending resistance and torsional rigidity than other section form; 3, conveniently, case beam can make large-scale installation unit in factory for installation and maintenance, thus reduces the workload of building site connection, is applicable to the construction method of longitudinal pull and pushing tow; Box-type section simple structure, during maintenance, paint is convenient, and form a closed space because it is inner, corrosion resistance improves; 4, lightly attractive in appearance, because box depth of beam is lower, and stiffening element and diaphragm are all located at the inside of beam, so profile is succinct, the lines flow smoothly.Early stage box beam is generally middle span, adopt many casees or single-box multi-cell cross section, analytical method continues to use the concept of load relieving system, is divided into by box-type section some i-shaped beamses to calculate, not considering the overall torsional rigidity of box-type section, is obviously coarse approximation method.Afterwards due to the appearance of Long span list case thin-wall box beam, box beam was analyzed as by the curved thin-wall member turned round by side.
Summary of the invention
