Iyo dhayamita yepini yekuchengetedza inofanirwa kutariswa zvinoenderana nemamiriro esimba ekuveurwa kana yaremerwa.Kune zvigadzirwa zvepini zvakaita seDIN1 neDIN7, chinodiwa chikuru ndechekunyatsojeka.Kushivirira kwepini yenyika cylindrical 8m6 ndeye φ8m6 (+0.015/+0.006);kutsauka kwepamusoro ndiko +0.015, kuderera kwepasi ndiko +0.006;saizi yepamusoro yekugumira ndeye φ8.015, saizi yediki muganho ndeye φ8.006, uye nzvimbo yekushivirira ndeye 0.009.Kushivirira kwesimbi isina tsvina cylindrical pini 10 h8 ndeye φ10 h8 (0/-0.022), kutsauka kwepamusoro ndeye 0, uye kutsauka kwepasi -0.022.Hukuru hwemuganho saizi ndeye φ10, saizi yediki muganho ndeye φ9.978, uye nzvimbo yekushivirira ndeye 0.022.Pini dzinowanzo shandiswa kubatanidza, kukiya zvikamu kana kumisikidza gungano, uye zvakare inogona kushandiswa sezvikamu zvemidziyo yekuchengetedza.Cylindrical pini dzakagadziriswa mumakomba nekuvhiringidza kugadzirisa zvikamu, kutumira simba, kana kuita sezvikamu zvekuisa.Ma cylindrical pini mapini ekumisa anoshandiswa kugadzirisa hukama pakati pezvikamu.Icho chikamu chakakosha chekubatsira kana chakabatanidzwa kugadzirisa uye kusangana.Cylindrical pini anonyanya kugadzirwa emhando yepamusoro kabhoni structural simbi semidziyo.Mumamiriro ezvinhu akajairika, zvinhu zvinonyanya kuC35 neC45, asi kurapwa kwekupisa kunodiwa.Kutakura simbi kunosarudzwa pasi pesimba rakakwirira zvinodiwa.Simbi isina tsvina inonyanya kugadzirwa ne303 zvinhu uye haidi kurapwa kwekupisa.Iyo elastic cylindrical pini inowanzoita 65Mn.
Anchors ndeemhando dzinotevera:
(1) Kuwedzera anchor bhaudhi
Kuwedzera mabhaudhi anchor, anonzi mabhaudhi ekuwedzera, shandisa mafambiro akaenzana ekoni uye pepa rekuwedzera (kana sleeve yekuwedzera) kusimudzira kuwedzera kwepepa rekuwedzera, kuburitsa simba rekuwedzera uye rekuwedzera nekongiri pamadziro egomba, uye kugadzira. kudhonza-kubuda kuramba kuburikidza neshear friction.Chikamu chinoona kusungirirwa kwechidimbu chakabatana.Kuwedzera anchor mabhoti akakamurwa kuita torque control mhando uye displacement yekudzora mhando zvinoenderana neakasiyana ekuwedzera simba rekudzora nzira panguva yekuisa.Iyo yekutanga inodzorwa ne torque, uye iyo yekupedzisira inodzorwa nekudzingwa.
(2) Reaming mhando anchor bhaudhi
Reaming type anchors, inonzi reaming bolts kana grooving bolts, iri kurovera patsva uye kudzokorodza kwekongiri pazasi pegomba rakacherwa, uchishandisa iyo mechanic interlock pakati pekongiri inotakura nzvimbo yakaumbwa mushure mekudzokorora uye musoro wekuwedzera weiyo anchor bolt. ., chikamu chinoona kusungirirwa kwechidimbu chakabatanidzwa.Reaming anchor bolts yakakamurwa kuita pre-reaming uye yekuzvimisikidza zvinoenderana nenzira dzakasiyana dzekugadzirisa.Iyo yekutanga iri pre-grooving uye reming nechakakosha chekuchera chishandiso;iyo yekupedzisira anchor bhaudhi inouya nechishandiso, iyo inozvimisikidza uye reming panguva yekuisa, uye grooving uye kuiswa kunopedzwa panguva imwe.
(3) Bonded mabhaudhi anchor
Bonded anchor bolts, anozivikanwawo semakemikari bonding bolts, anonzi mabhoti emakemikari kana mabhoti ekubatanidza, anogadzirwa neakakosha makemikari anonamira (anchoring glue) kunama nekugadzirisa screws uye mukati meshinda mapombi mumakomba ekuchera ekongiri substrates.Iyo yekubatanidza uye yekuvhara basa pakati pekunamira uye sikuruu uye yekunamira uye nekongiri gomba madziro kuti uone chikamu chakasungirirwa kune chakabatana chimedu.
(4) Kemikari kudyara tendon
Kemikari yekudyara bhaa inosanganisira simbi yakarukwa uye refu screw rod, inova post-anchor yekubatanidza tekinoroji inoshandiswa zvakanyanya mumatenderedzwa einjiniya enyika yangu.Iyo anchorage yekemikari yekudyara mabara yakafanana neyekusunga mabhaudhi anchor, asi nekuti kureba kwemakemikari ekudyara mabharu uye marefu screws haana kuganhurirwa, yakafanana neanchorage yeakakandirwa-mu-nzvimbo kongiri mbariro, uye kukuvadza fomu. iri nyore kudzora, uye kazhinji inogona kudzorwa sekukuvadzwa kwemaanchor bars.Naizvozvo, inokodzera kubatanidza anchorage yenhengo dzezvimiro kana dzisiri nhengo dzechimiro dzine static uye seismic fortification intensity iri pasi kana kuenzana ne8.
(5) Kongiri
Chimiro uye anchoring mechanism yekongiri screws yakafanana neyehuni screws.Chinhu chakakosha chinoshandiswa kukungurutsa nekudzima shinda yakaoma uye inopinza yebanga.Panguva yekuisa, gomba rakananga rine dhayamita diki rinofanoroverwa, uye ipapo screw inoputirwa mukati, uchishandisa shinda uye gomba.Iyo occlusal chiito pakati pemadziro kongiri inoburitsa simba rekudhonza-kunze uye inoona chikamu chinosungirirwa kune zvakabatanidzwa zvikamu.
(6) Kupfura zvipikiri
Kupfura mbambo imhando yepamusoro-yakaoma zvipikiri zvesimbi, zvinosanganisira screws, iyo inosundwa nepfuti, mukongiri, uye inoshandisa kupisa kwayo kwepamusoro (900 ° C) kugadzira zvipikiri zvesimbi nekongiri zvakabatanidzwa nekuda kwemakemikari fusion uye clamping.Ziva anchoring yezvikamu zvakabatana.
