Self-drilling anchors imhando yakakosha yetsvimbo anchor.Masimbi ekuzviboorera anosanganisira mabhiti ekubaira, masimbi asina mhango emadhayamita akakodzera ekunze nemukati, uye nzungu dzinobatanidza.
Muviri weanchor wakagadzirwa nehollow simbi pombi ine shinda yekunze.Iyo chubhu yesimbi ine chibairo chidimbu kune imwe mugumo uye inoenderana nati ine simbi yekupedzisira ndiro.
Kuzviboorera anchors anoshandiswa nenzira yekuti hollow rebar (tsvimbo) ine inowirirana chibayiro bhiti pamusoro payo pachinzvimbo chezvakajairwa bhiti.
Mudziyo wepakati unovimbisa kuvharika kwegrout kwakatenderedza buri rebar uye kuti rebar inoramba iri pakati pegomba rakacherwa.
Anchoring hollow mabara anogadzirwa mumaprofiles ane mwero hurefu hwe2.0, 3.0 kana 4.0 m.Iyo yakajairwa yekunze dhayamita yesimbi isina masimbi inotangira kubva pa30.0 mm kusvika 127.0 mm.
Kana zvichidikanwa, masimbi esimbi asina maburi anobatanidzwa nekubatanidza nzungu.Zvichienderana nemhando yevhu kana dombo, marudzi akasiyana ezvibairo anoshandiswa.Hollow mabara akakwirira kune akasimba mabara ane yakafanana-chikamu-chikamu nzvimbo nekuda kwezvimiro zvadzo zviri nani maererano nebuckling, perimeter (nzvimbo yakasungirirwa), uye kuomarara kwekukotama.Mhedzisiro ndeyekukwirisa buckling uye kubhenda kugadzikana kune imwecheteyo simbi (material cost).
