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.
