Intsimbi ephezuluingasetyenziselwa kwizakhiwo zetsimbi ukugcina inani lensimbi esetyenzisiweyo kunye nokunciphisa iindleko zokwenza i-steel structure, ukuthutha kunye nokufakwa.Ekubeni iimpawu mechanical of high-amandla intsimbi zineeyantlukwano non-engahoywayo ngentsimbi eqhelekileyo, abaphengululi ekhaya nakwamanye amazwe baye benza umsebenzi omninzi wophando kwisicelo sentsimbi yesakhiwo esiphakamileyo kwiminyaka yamuva.

Ukongeza kuyilo lwelungu olunengqiqo, izakhiwo zetsimbi eziphezulu zifuna uxhulumaniso olusebenzayo phakathi kwamalungu ensimbi ephezulu ukuze enze isakhiwo esikhuselekileyo nesithembekileyo.

Inkqubela phambili yophando yeendlela ezimbini ezibalulekileyo zokudibanisa intsimbi ephezulu (i-welding kunye ne-bolting) ekhaya nakwamanye amazwe iyaziswa, kubandakanywa: uphando malunga nokusebenza komthwalo wentsimbi ephezulu yokudibanisa i-butt-weld, uphando malunga nomthwalo wokuthwala. ukusebenza koxhulumaniso oluphezulu lwentsimbi yentsimbi yentsimbi, uphando malunga nokusebenza komthwalo wentsimbi ephezulu yamandla e-friction-type bolting, uphando malunga nokunyanzeliswa komthwalo wentsimbi ephezulu yokunyanzeliswa kwe-bolting kunye nophando kwi-hydrogen- ukulibaziseka ukwaphuka kweebholithi zokuqina kwebanga le-12.9, njl. njl., kwaye iqaqambisa inkqubela yophando lweYunivesithi yaseTongji.IYunivesithi yaseTongji, ishwankathela inkqubela yophando olukhoyo kunye nokujonga phambili kuphando lwexesha elizayo.

Ukusetyenziswa kokulinganisa okungaphantsi kwamandla kwi-butt welding yentsimbi ephezulu yokuqina kunokunciphisa ukushisa kwe-welding preheating, ukunciphisa iziphene ze-welding kunye nokuphucula i-ductility ye-joint.

Nangona kunjalo, ukuhambelana okungaphantsi kwamandla kunokuba nefuthe elibalulekileyo kumthamo womthwalo we-welded joint.Abaphandi abaninzi baye babonisa ukuba iziphumo zekhowudi yaseYurophu ye-EC3 kwi-under-strength matching of welded joints strength calculation provisions are basically reasonable or conservative.

High-amandla intsimbi ukuthamba isenzeko emva ukuwelda kunye nobungakanani iqondo ukuthamba kunye nentsimbi ukomeleza indlela, inkqubo rolling kunye novakalelo kunyango ubushushu, ngenxa high-amandla entsimbi kwinkqubo yokuqengqeleka iye enye okanye ngaphezulu unyango ubushushu, intsimbi kufutshane. i-weld kunye negalelo lobushushu kunye nokupholisa umjikelo wokupholisa ubushushu, ukuze ingakwazi ukugcina iipropati ze-original mechanical, kwaye ngoko ke indawo echaphazelekayo ngubushushu.

Imiba ethile echaphazela ukomelela komdibaniso odityanisiweyo ibandakanya ukomelela kwesixhobo se-weld, ububanzi bommandla we-weld, amandla ommandla wokuthamba, ububanzi bendawo ethambileyo, ububanzi bobukhulu bomlinganiselo wenxalenye edibeneyo kunye ne-angle ye-weld bevel.

I-1) iindlela ezahlukeneyo zokuthatha umthwalo we-slip zinempembelelo enkulu kwi-coefficient echasene ne-slip, kwaye ixabiso le-anti-slip coefficient yekhowudi yaseTshayina yi-7% ukuya kwi-20% enkulu kunexabiso lekhowudi yaseYurophu.

I-2) Kwindawo yokudubula i-shot blasting surface, ixabiso elilinganisiweyo le-anti-slip coefficient ye-high-high-high-strey-steel iphakathi kwe-0.45 kunye ne-0.50 ngokwekhowudi yaseYurophu, kwaye ukuba izinga elithile lokuqinisekisa ukhuseleko liqwalaselwa, ixabiso loyilo elihambelanayo liphakathi. 0.4 kunye ne-0.45.

3) TI-anti-slip coefficient yomgangatho obomvu womhlwa emva kokudutyulwa kokudubula kwentsimbi ephezulu kakhulu ngokuqhelekileyo inkulu kunomhlaba oqhushumbayo.

4) Tyena anti-slip coefficient ofphezulu tensilesucingo lobudeumphezulu webrashi ngokwemigaqo yaseYurophu isondele kwixabiso elithathwe ngokwemigaqo yaseTshayina, i-anti-slip coefficient iyancipha ngokunyuka kwebakala lamandla entsimbi.

I-5) Unyango oluphezulu lwentsimbi ephezulu yokudubula kunye nepeyinti ye-zinc ecebileyo ye-inorganic inokunyusa ukuzinza kwe-anti-slip coefficient ye-friction surface, kwaye umgangatho we-anti-slip coefficient ngokuqhelekileyo uncinci kunomnye umphezulu. iindlela zonyango.Ubukhulu bepeyinti yepeyinti ecebileyo ye-zinc inceda ekuphuculeni i-coefficient yokumelana nokutyibilika, kwaye i-coefficient yokumelana ne-slip ye-coefficient ye-coefficient engqingqwa malunga ne-10% ephezulu kune-coefficient ebhityileyo.
