Isikulufu sehange
Ama-anchor bolt ama-screw rods asetshenziselwa ukubopha izinto zokusebenza, njll. ezisekelweni zikakhonkolo.Ngokujwayelekile isetshenziswa kwingqalasizinda efana nojantshi, imigwaqo emikhulu, amabhizinisi aphehla amandla kagesi, izimboni, izimayini, amabhuloho, ama-cranes ombhoshongo, izakhiwo zensimbi ezinkulu kanye nezakhiwo ezinkulu.Inokuqina okuqinile.
Ukucaciswa
Amabhawodi okusetshenzwa kulengwa ngokuvamile asebenzisa i-Q235 ne-Q345, eyindilinga.Kubonakala sengathi angizange ngikubone ukusetshenziswa kwemicu, kodwa uma amandla ekudinga, akuwona umqondo omubi.I-Rebar (Q345) iqinile, futhi intambo ye-nati akulula ukuba ibe yindilinga.Ukuze uthole amabhawodi ahange ayindilinga alula, ukujula kokungcwaba ngokuvamile kuwubukhulu obuphindwe izikhathi ezingu-25, bese kwenziwa ihuku engama-degree angu-90 enobude obungaba ngu-120mm.Uma ububanzi be-bolt bukhulu (njengo-45mm) futhi ukujula okungcwatshwe kujule kakhulu, ipuleti yesikwele ingashiswa ekupheleni kwebholithi, okungukuthi, ikhanda elikhulu lingenziwa (kodwa kunezidingo ezithile).Ukujula kokungcwaba kanye nehhuku konke ukuqinisekisa ukungqubuzana phakathi kwebhawodi nesisekelo, ukuze kungabangeli ukuthi ibhawudi likhishwe futhi lonakaliswe.Ngakho-ke, amandla okuqina webhawodi okusetshenzwa kulengwa kuwo amandla aqinile ensimbi eyindilinga ngokwayo, futhi ubukhulu bulingana nendawo enqamula ingxenye ephindwe ngenani lokuklama lamandla aqinile (140MPa), okuwumthamo ovumelekile wokuthwala ukuqina. ngesikhathi sokuklama.Umthamo wokugcina wokuqina uwukuphindaphinda indawo yayo ephambanayo (okumele kube indawo esebenza kahle entanjeni) ngamandla aqinile ensimbi (amandla e-Q235 aqinile angama-235MPa).Njengoba inani lokuklama lisohlangothini oluphephile, amandla aqinile ngesikhathi sokuklama angaphansi kwamandla okugcina.
Inqubo yokufaka
Ukufakwa kwama-anchor bolt ngokuvamile kuhlukaniswa ngezinqubo ezi-4.
1. Ukuma kwamabhawodi okusetshenzwa kulengwa
Amabhawodi okusetshenzwa kulengwa kuwo kufanele afakwe mpo ngaphandle kokuthambekela.
2. Ukufakwa kwamabhawodi okusetshenzwa kulengwa
Ngesikhathi sokufakwa kwamabholiti okusetshenzwa kulengwa, kuvame ukuhlangana nesibili i-grouting ye-anchor bolts efile, okungukuthi, lapho isisekelo sithelwa, izimbobo ezibekelwe izimbobo zehange zigcinwe kusenesikhathi esisekelweni, futhi izimbobo zehange ziyafakwa. ngesikhathi impahla isifakiwe.amabhawudi, bese uthela amabhawodi okusetshenzwa kulengwa kuze afe ngosimende noma usimende.
3. Ukufakwa kwebhawodi lehange - qinisa
4. Yenza amarekhodi okwakha ukuze kufakwe amabhawodi ahange ahambisanayo
Phakathi nenqubo yokufakwa kwamabhawudo okusetshenzwa kulengwa kuwo, amarekhodi okwakha ahambisanayo kufanele enziwe ngokuningiliziwe, futhi uhlobo nezicaciso zamabhawodi okusetshenzwa kulengwa kuzo kufanele kubonakale ngempela, ukuze kuhlinzekwe ulwazi olusebenzayo lwezobuchwepheshe ukuze kugcinwe isikhathi esizayo futhi kushintshwe.
Ngokujwayelekile, izingxenye ezishumekwe ngaphambili ezinokunemba okuphezulu kokufaka kufanele zenziwe amakheji angaphansi komhlaba (amapuleti ensimbi ashumekwe ngaphambili abhotshozwe emigodini yebhawudi kufanele agqokwe kuqala, futhi amantongomane kufanele afakwe ukuze awacindezele phansi. izingxenye ezishunyekiwe ngaphambili kufanele ziboshwe ku-formwork futhi zilungiswe.Usayizi wokufaka wamabhowuthi onyawo ungaqinisekiswa.Uma ufuna ukulondoloza izinto zokwakha, ungasebenzisa futhi izinsimbi zensimbi ukuze uzishise futhi uzilungise.Ngemva kokuba ukushisela kuqediwe, udinga ukuhlola ubukhulu bejiyomethri.Kuleli qophelo, ukufakwa kwebhawodi lonyawo kuqediwe ngempela.
Okujwayelekile
Amazwe anezincazelo namazinga ahlukene, afana nezinga laseBrithani, ezomthetho, lesiJalimane, lase-Australia kanye nezinga laseMelika.
Izimbangela Zokugqwala
(1) Isizathu sendaba.Nakuba amanye ama-anchor bolt engathintani ngokuqondile nendawo ephakathi nendawo, ngenxa yezizathu ezihlukahlukene, indawo edlayo cishe izodluliselwa kumabhawodi okusetshenzwa kulengwa kuwo, okubangele ukuba amabhawodi okusetshenzwa kulengwa agle.
(2) Izizathu zemvelo.Amabhawodi ensimbi ekhabhoni azogqwala ezindaweni ezimanzi.
(3) Isizathu sempahla yebhawodi.Ekwakhiweni, nakuba ama-anchor bolts ekhethiwe ngokuvumelana nemithethonqubo, ngokuvamile acabangela amandla ama-bolts kuphela futhi awacabangi ukuthi ngaphansi kwezimo ezikhethekile, ama-anchor bolts azogqwala ngesikhathi sokusetshenziswa, ngakho-ke izinto ezivimbela ukugqwala ezifana ne-stainless. insimbi ayisetshenziswa.
