Uva 'isiqhoboshi esixhonyiweyo' kwaye uninzi lwabantu, nkqu nabanye abakwishishini, ngokukhawuleza bafanekisela i-J-bolt elula okanye intonga enemisonto ejinga kwidekhi yekhonkrithi. Leyo yimbono yokuqala ephosakeleyo. Asiyonxalenye nje ejingayo; yinkqubo yonke-intsebenziswano phakathi kwe-fastener, umqadi, i-embedment, kunye nemithwalo eguqukayo ekuhambeni kwexesha. Olona celomngeni asikokubambisa namhlanje; iqinisekisa ukuba ayibi luxanduva kwiminyaka emihlanu ngenxa yokungcangcazela, umhlwa, okanye ukudinwa ngokupheleleyo. Ndibone i-specs ebiza i-ankile yekhemikhali ye-M20 yetreyi yentambo ekhanyayo, engaphezulu kakhulu, kunye nabanye abazama ukusebenzisa i-ankile ye-wedge kwikhonkrithi eqhekekileyo kwiyunithi ye-HVAC ebalulekileyo, ecela ingxaki. Ukhetho yinto yonke.

Umsebenzi ongundoqo kunye neMigibe eqhelekileyo

Masiwuchithe umsebenzi. Owona msebenzi uphambili wesiqhoboshi esinqunyanyisiweyo kukudlulisa umthwalo usuka kwinto enqunyanyisiweyo-nokuba ngumbhobho, umbhobho, intsimbi yesibini, okanye igridi yesilingi yobuxoki—ukubuyisela kwisakhiwo esingaphezulu sentloko. Indawo yokungaphumeleli ayifane ibe sisiqhoboshi ngokwaso siqhwabe; iqhelekile kujongano. Ukutsalwa ngaphandle kwekhonkrithi, ukuqhekeka malunga nommandla wokufakela, okanye ukukhulula ngenxa yokungcangcazela. Ndikhumbula iprojekthi apho sasebenzisa i-anchor zokwandisa umgangatho wenkqubo yenkxaso yokuhambisa. Baluphumelele uvavanyo lokuqala lomthwalo, kodwa kwisithuba seenyanga ezintandathu zokusebenza, ukungcangcazela okungaguqukiyo, okuphantsi kwamaza aphantsi kuye kwasebenza isiqingatha sabo sakhululeka. Ukulungiswa kwaba kukuvalwa kweendleko kunye nokutshintshela kwinkqubo efanelekileyo yokumelana nokungcangcazela.

Ukuhambelana kwezinto ngomnye umbulali othuleyo. Kwi-retrofit yesityalo sekhemikhali, sixhome umqadi wenkxaso yensimbi engenasici. I-spec yabiza ii-ankile ezingenasici, kodwa i-slab yekhonkrithi yayinomxholo ophezulu we-chloride ukusuka kwiminyaka yokuvezwa. Siye sagqiba nge-galvanic corrosion kwi-interface yentambo, sibeka esichengeni ngokungqongqo umthwalo we-clamp. Sifunda ntoni? I-fastener material kufuneka ikhethwe ngokusingqongileyo, kungekhona nje i-beam. Ngamanye amaxesha, i-ankile ye-galvanized galvanized carbon steel iankile kumkhono wokwahlula ikrelekrele kunexabiso elingenastained ehleli ngqo kwikhonkrithi enobundlobongela.

Emva koko kukho umba wokufikelela kunye nokufakwa. Wonke umntu uzoba isiqhoboshi esicocekileyo kwisicwangciso. Kwindawo, ufumana iwebhu eshinyeneyo ye-rebar kanye apho kufuneka uqhube khona. Awunako ukuyitshintsha nje nge-10 cm ngaphandle kokuchaphazela yonke iplani yenkxaso esezantsi. Oku kulapho iqondo lokuguquguquka kwinkqubo ye-fastener ihlawula. Ukuba noyilo oluvumela uhlengahlengiso oluthile kwi-bracket okanye ukusebenzisa inkqubo yetshaneli njengeyona ndawo iphambili ye-anchor, apho unokuxhoma khona imiqadi kwiindawo ezahlukeneyo, igcina iiyure ezininzi zabantu kunye neentloko. Asiyothiyori; kukugaya kwemihla ngemihla.

Iinyani zeMveliso kunye neMeko yoMboneleli

Ukukhangela imarike yemveliso ngumsebenzi wayo. Uneempawu ezinkulu zaseYurophu nezaseMelika ezityhala iinkqubo zabo zobunjineli, ezigqwesileyo kodwa ziza nethegi yexabiso elinokuthi livuthulule uhlahlo lwabiwo-mali kwiprojekthi yemizi-mveliso emikhulu. Emva koko uneendawo zokuvelisa zasekhaya, ezihlala zijongelwa phantsi. Thatha indawo efana neSithili saseYongnian eHandan. Sisiseko esikhulu semveliso samalungu asemgangathweni eTshayina. Inkampani esebenza apho, njengaye I-Sunnian Zitai Festener Fishaner Comment Com., ihleli kanye entliziyweni yaloo nkqubo yendalo. Indawo yabo, ekufuphi noololiwe abakhulu kunye nothungelwano lweendlela, ayingomgca nje kwiwebhusayithi (https //wwww.ziitasteners.com); iguqulela kwimpumelelo yolungiselelo kwiiodolo ezininzi. Kwizicelo zomgangatho omisiweyo we-beam-cinga i-MEP yokwakha yorhwebo ixhasa, izibonelelo ezingabalulekanga-imithombo evela kwisiseko esikhethekileyo sokuvelisa inokuba yimali elungeleleneyo yeendleko, umthamo, kunye nomgangatho ongaguqukiyo.

Nangona kunjalo, ipragmatism ifuna ukuqinisekiswa. Ukuodola ibhetshi ye iifasteners ezimisiweyo nakuwuphi na umthengisi, wasekhaya okanye wamazwe ngamazwe, kuthetha ukuba kufuneka ube neyakho iprothokholi ye-QA. Ayikokungathembani, koko kukukhuthala emsebenzini. Siza kuvavanya iibhetshi zeesampulu zokuchaneka komda, ubukhulu bokugquma ukuba bufakwe igalvan, kunye nokomelela kokugqibela. Ndikhumbula uthutho apho intambo yentambo yayicinywe ngeqhezu kwibhetshi yeentonga zemisonto yonke eyenzelwe izibophelelo zemiqadi. Yayingabonakali ngeso, kodwa ibangele i-cross-threading ngexesha lofakelo, ukonakalisa amantongomane kunye nokucotha umsebenzi. Umthengisi uye walungisa, kodwa ukulibaziseka kwaba yinto yethu yokufunxa.

Isitshixo sihambelana nemveliso ekubalulekeni kwesicelo. Ngommandla wenyikima okanye inkxaso yomatshini wokungcangcazela onzima, udinga inkqubo eqinisekisiweyo, enokulandeleka enedatha yomthwalo oguqukayo opapashiweyo. Ukuxhoma inethiwekhi yee-ladders ze-cable lightweight kwisakhiwo seofisi, isisombululo esinokwethenjelwa, esinexabiso eliphantsi esivela kumvelisi wevolumu njengalawo aseYongnian / Handan kwingingqi kaninzi ilona khetho olunengqiqo. Imalunga nokwabiwa komngcipheko weprojekthi kunye nohlahlo lwabiwo-mali ngokufanelekileyo kumawakawaka amanqaku onxibelelwano.

Ukufakela: Apho ithiyori idibana neNyaniso

Kulapho izicwangciso zidla ngokuwa. Ukuqonda kwabasebenzi abafakelweyo kubaluleke kakhulu. Amandla e-ankile yeekhemikhali axhomekeke ngokupheleleyo ekucoceni umngxuma ochanekileyo. Ukuba abayisebenzisi i-brush, bavuthele uthuli, kwaye uphinde, iibhondi ze-resin zibe luthuli, kungekhona ikhonkrithi. Umthwalo wokusilela unokuba sisiqingatha sento elindelekileyo. Ndenze umkhwa ukwenza iitshekhi zeendawo ezingachazwanga, ukutsala isikrufu setorque okanye umvavanyi wempompo elula ukujonga izandi ezingenanto malunga nokushumeka.

I-Torque ngokuchasene noxinzelelo yenye ukubhideka kwendawo yakudala. I-torque ekhankanyiweyo ye-anchor yomatshini kukufezekisa ukulayisha kwangaphambili (i-clamp force) kwintonga. Ukugqwesa i-ankile ye-wedge kunokwandisa umkhono kakhulu kwaye kuqhekeze i-substrate yekhonkrithi, ngakumbi kufuphi nemiphetho. Ukulawula ngaphantsi kuthetha ukuba umqadi onqunyanyisiweyo awubotshwanga kakuhle kwaye unokushukuma. Ukusebenzisa isikrufu esilungelelanisiweyo kunye nokuqeqesha abasebenzi 'kwimvakalelo' linyathelo elisisiseko kodwa elisoloko lingahoywa. Siqale ukubandakanya intetho enyanzelekileyo yemizuzu eli-15 yebhokisi yesixhobo kulo lonke iqela elitsha, kwaye izinga lokufowuna lokubuyela umva kwizinto ezifakiweyo lehle ngokubonakalayo.

Emva koko kukho uqhagamshelo lomqadi ngokwalo. I isiqhoboshi ikwikhonkrithi, kodwa idibana njani nomqadi? Isibambiso somthi, iclevis, ipleyiti edityanisiweyo? Ukudibanisa intsimi kwi-galvanized beam kufuna ukugaya i-coating, i-welding, kwaye emva koko iphinde iphathe indawo, ehlala isenziwa kakubi, idala i-rust spot yekamva. Iiclamp zoomatshini ziyakhawuleza kwaye zigcina i-coating, kodwa kufuneka uqinisekise ukuba i-clamp ilinganiselwe umthwalo kunye nobukhulu be-flange ye-beam. Ndibone iiclamps zityibilika ngenxa yokuba zenzelwe i-10mm flange kodwa zifakwe kwi-12mm enye.

Izifundo ezivela kuMmandla kunye neZenzo eziPhuculayo

Isifundo esibuhlungu sasikwiprojekthi yesitora esinentsimbi ezidibanisa ixesha elide. Sisebenzise i-ankile yokulahla eyaziwayo kwiindawo zokunqunyanyiswa. Ukugalelwa kwekonkile kwakusebusika, kwaye ukunyangwa kwakungafanelekanga. Kamva, ngexesha lofakelo, ii-ankile ezininzi zatsala ngaphantsi nje kokuqinisa isandla. Uphando lwalatha ukuqhekeka okuncinci kwi-ankile ngenxa yokuba amandla ekhonkrithi aselula abengaphantsi kunokuba bekucingelwa. Sitshintshele kwinkqubo ye-anchor ye-undercut yeendawo ezisele, ezenza ngcono kwi-concrete engaphantsi kune-perfect. Yayixabisa ngaphezulu, kodwa yasebenza. Ngoku, kuwo nawuphi na umthwalo onqunyanyisiweyo ngaphaya komda othile, sinyanzelisa inkqubo yovavanyo lofakelo lwangaphambili lweankile kweyona substrate.

Umzila ngoku usiya kwiinkqubo ezidibeneyo, ngakumbi kwiiprojekthi eziqhutywa yi-BIM. Incinci malunga nokuzimela isiqhoboshi esimisiweyo kunye nokunye malunga nenkqubo yenkxaso elungelelanisiweyo: itshaneli ephambili egxininiswe kwi-slab ene-anchors ezinobunzima obunzima, kunye ne-trapeze hangers okanye i-clamps ye-beam ecofa kwijelo. Oku kuvumela ukulungelelaniswa, ukunciphisa ukuguqulwa kwexesha elizayo, kunye nokwenza lula ukubalwa kwendlela yomthwalo. Iinkampani ezenza zombini i-fasteners kunye ne-hardware yenkxaso, enikezela ngenkqubo evavanyiweyo, bafumana umhlaba. Ihambisa uxanduva ukusuka kubasebenzi besiza beyidibanisa kunye kwisisombululo esenziwe ngobunjineli.

Ukujonga emva, olona tshintsho lukhulu kwingcinga yam luye lwavela ekuyiboneni njengento ethengiswayo ukuyijonga njengekhonkco elibalulekileyo kwikhonkco lomthwalo. Awunako nje ukubiyela inxalenye yenombolo kwishedyuli. Kufuneka uqwalasele i-substrate, indalo, uhlobo lomthwalo (i-static, i-dynamic, i-seismic), iimeko zokufakela, kunye nokugcinwa kwexesha elide. Ngamanye amaxesha impendulo echanekileyo yinkqubo ye-premium evela kwi-brand yehlabathi. Ngamanye amaxesha, licandelo elomeleleyo, elingagungqiyo ukusuka kwisiseko esikhulu sokwenziwa kwemveliso efana nale. Handan Zitai Fastener isebenza ngaphakathi. Umnxeba wokugweba phakathi kwezo ndlela zikhethwayo, ngokusekelwe kwiimfuno zeprojekthi ethile kunye nemiqobo, luphawu lokwenyani lwamava. Ayikhe ibeyibholithi nje.
