The Technique Studying Of Large Span T Beam Prefabrication And Hoistiong

Prepare in response to the dint reinforced concrete beam bridge a building at the domestic and international bridge up occupy an important position, have strength high , self-respect small, economical steel materia , enduring of characteristics, apply scope wide, have already make widely available in the our country, the T form beam bridge is the most widespread in the every kind of assemble type beam bridge, but only 10,13,16 and 20 m four kinds of highway beam bridge standardses design in our country have already dreamed the standard across the path,but along with the development of bridge construction craft and new bridging machine apply, the T beam acrosses path also growing,the 50m T beam is already very widespread in the bridge engineering,also present the situation of significant growth, but prepare to make and mourn cultural heritage data of pack the technique research to the 50 mT beam few,become the check and supervision T beam the bottleneck of the development.Therefore, the 50m T beam that this topic study prepares to make and mourns to pack a technique have huge instruction meaning to the construction. This topic is in the process of study in carried on a great deal of investigation work, Combine just in the construction engineering of Shide,Jingjiu railroad acrosses line bridge engineering of Hengshui downtown segment one class highway, in making reference to the foundation concerning cultural heritage go deep into the spot of 50m T beam to prepare to make,mourn to pack engineering, make theories close the contact be actual, have very strong conviction, collected part picture of prepare to make, mourn to pack in the process of investigating research, make the topic more image to comprehend. Main from the following everywhere the noodles carried on a research in the process of study:â‘ Engineering general situation;â‘¡Prepare to make,Pull to stretch and press syrup craft of the 50m prepares in response to the dint T beam;â‘¢Transport on the 50m T beam bridge;â‘£The bridging machine acrosses railroad beam.At introduce T beam to prepare to make and Pull to stretch 's craft of in the meantime,carried on a set to prepare an arch degree,join addition's concrete match to compare really settle,elongation quantity etc. theories calculation, for promising the safety and rationality of the bridging machine install beam, carry on calculation examination to acrossed the bridge conveyance T beam, in wholely the calculation process, the writer collected a great deal of spot data to carry on analysis, also compute theories formula to calculate of result and bridge constucted the expert's opinion to carry on contrast analysis, make use of engineering construction physically medium, verified the rationality of this literary style ory formula, and for Other alike regions 50m T beam prepares to make with installed construction provide precious experience of 50m T beam.
