qhov chaw ncej ib leeg steel truss

(1) Kev tsim khoom thiab kev teeb tsa ntawm cov qauv hlau yuav tsum ua raws li cov kev cai ntawm "Code for Construction and Acceptance of Steel Structures" (GB50205-2001).

(2) Kev tshuaj xyuas qib ntawm vuam zoo
Rau lub Hoobkas splicing-slag welds ntawm cov khoom tseem ceeb ntawm cov khoom thiab cov yaj welds ntawm qhov chaw sib dhos interface, cov vuam seam yuav tsum raug tshuaj xyuas los ntawm qib II, thiab cov welds thiab cov tsis yaj welds yuav tsum raug tshuaj xyuas los ntawm qib III.

(3) Vuam seam ntawm cov yeeb nkab sib tshuam interface:
Tag nrho cov yeeb nkab steel sib tshuam welds yog fillet welds, thiab daim ntawv vuam yuav tsum ua kom tau raws li qhov yuav tsum tau ntawm kev tsim lossis lwm yam specifications.

(4) lub splicing ntawm lub truss lub ntsiab chord yuav tsum tsis txhob tshwm sim nyob rau hauv tib seem, thiab splicing weld daim ntawv ntawm lub ntsiab chord yuav tsum tau raws li qhov yuav tsum tau ntawm tus tsim thiab lwm yam specifications.

(5) Tag nrho cov trusses yuav tsum tau ua nyob rau hauv seem, thiab lub Hoobkas yuav tsum ua nruj me ntsis pre-assembly.Kev sib dhos tag nrho yuav tsum tau ua tom qab dhau qhov kev tshuaj xyuas ntawm cov khoom siv (nrog rau kev tshuaj xyuas ntawm vuam seam ntawm kev sib dhos) ntawm qhov chaw.
(6) Hauv cov txheej txheem ntawm kev khaws cia thiab kev thauj mus los, kev ntsuas yuav tsum tau coj los tiv thaiv kev khoov thiab deformation ntawm cov khoom.
