the mold and wing imitate to adopt the steel template inner pad bamboo gum plank construction craft, the application of the new craft ability bigRaises a box of beam external appearance quality.Its craft process is as follows:(Pay a scaffold) the steel pipe spreads the steel template spreads bamboo gum the plank(spread reinforcing bar) clean up(Sprinkle to build concrete).(2)Box beam crest the template adopt a light material template-Ling mold inside the magnesium.The Ling mold inside the magnesium belongs to permanent sex template,As well calling a time of template of consuming is a template dont tore down after the structure reaches a concrete to sprinkle to build, and constitute to reach a piece dont be subjected toThe dint constitutes part.3.the reinforcing bar process and build(slightly)4.the concrete sprinkle to buildBecause now sprinkle continuous box of beam concrete to measure a little bit greatly, this engineering adopts compulsive type concrete mixer from mix to mix NingSoil transports pump to pump the concrete into a mold with the concrete.Request to match with than should meet rules, the strength matches to establishAccount a request, sprinkle to build the sequence sprinkles to build to the Dun crest from acrossed, horizontal from hang arm plank to sprinkle to build to the Dun crest.The Jin Jin superhighway IV marks mutual communication type in the Chinese harbor highway to sign to hand over the organization design of starting constructionPage 20Figure 4-4 supports put together to packFigure 4-5 Ling molds inside the magnesium start construction

request, square can Zhang La prepare to tie in response to the dint.(1)Zhang Las material and tool elucidation:The steel wrings line:Adopt j 15.2 high strengths low relax 270 class steels to wring line, standard strength BE:RbY=1860 MPas.The anchor man has and enclosure:Adopt OVM15 and BM15 series anchor man to have and kit anchor man plastic sheet and spiral Jin.The anchor man hasThe beard matches current prepare to have and link a machine to apply a technical specification with the anchor man in response to the dint Jin .Prepare to prepare to cover up a gold in response to the dint piping adoptionBelong to a ripples tube to become bore.Above all material beards can use through taking out to check qualified rear of second examinations.Zhang Las machine tool:The jack adopts 1200 kNs and 200 kNs two kinds of specifications.All pieces pulling an equipments are before usingHave to pass by to correct, and pay to authenticate a report, is a reference document for pulling.You Liu promises gastight oil, electricityThe luck turns as usual, the manometer shows a stability.(2)Zhang Las project:Preparing to sprinkle to build in response to the dint beam should the completion, each reinforcing bar net and framework all need colligation to make itBecoming is whole, and accurate the steel preparing to cover up just curved Ju tie a ripples tube.Preparing to pull in response to the dint bunch piece should at be a beam body concrete strengthAttain 100%, and can carry on at sprinkling to build at the back of the 14 d, Zhang La should press syrup in time after completing, the preface of Zhang La Gong BE:0(the beginning starts in response to the dint)0.1 Rs are 1.03 R(the anchor man is solid)s, prepare to pull to depend on in response to the dint bunch piece symmetry originalThen carry on, the cross section wrings line to break silk or slippery the silk tie one silk with should control each time.Prepare to tie an adoption double to control Zhang La in response to the dint,Control in response to the dint contingency double.Zhang La is operated as follows:Zhang La goes forward to go jack and manometer kit examination
