FRP, ekwabizwa ngokuba yi-fiber-reinforced polymer, yimathiriyeli ehlanganisiweyo eyenziwe ngeentsinga ezomeleziweyo kunye neresin ye-matrix. Injongo yayo ephambili kukusombulula ingxaki yentsimbi yentsimbi eyenza buthathaka izakhiwo zekhonkrithi ezomeleziweyo zemveli.
I-FRP ineendlela ezahlukeneyo zokusetyenziswa kumashishini ahlukeneyo ngenxa yokukwazi ukulungelelaniswa kunye neentlobo ezahlukeneyo ze-resin ezisisiseko ezifana ne-polyester engaxutywanga, i-epoxy, i-vinyl ester, kunye ne-polyurethane. Ezi resin zineempawu ezizodwa ezenza ukuba i-FRP ihlangabezane noluhlu olubanzi lweemfuno.
Ukongezelela, i-FRP iphinda isebenzise iintlobo ezahlukeneyo zokuqinisa iifayili, kubandakanywa i-fiber yeglasi, i-basalt fiber kunye ne-carbon fiber, nganye ineempawu ezikhethekileyo ezifana namandla aphezulu, ukuxhathisa ukubola kunye nokuqina. Ngenxa yoko, i-FRP iba yimathiriyeli eguquguqukayo nesebenzayo yokwakha kunye nolwakhiwo lwezicelo.

Uluhlu lwe-FRPithathwa njengenye indlela esebenzayo kwirebar yentsimbi yemveli kwiiprojekthi zokwakha kwaye iya ithandwa kakhulu ngenxa yeenzuzo zayo ezizodwa.
Esinye sezizathu eziphambili zokuwohloka kweziseko zophuhliso kukugqwala kokuqiniswa kwentsimbi kwikhonkrithi. Oku akugcini nje ukunciphisa ubomi bekhonkrithi, kunokukhokelela ekunyuseni iindleko zokulungisa kunye neengozi zokhuseleko. Nangona kunjalo, ngokusebenzisa i-fiberglass rebar, ingxaki yomhlwa inokupheliswa ngokupheleleyo.
Umzekelo,IGRECHO i-fiberglass rebar iqulunqwe ngokupheleleyo ngezinto ezingezizo isinyithi, inika isisombululo esomeleleyo esikhuphisana neendleko kunye nentsimbi. Ukongeza, ukunganyaniseki kwayo kwe-electromagnetic kuyenza ilungele ukuthunyelwa kwiindawo ezinobuthathaka.
Ezi zilandelayo ziimpawu kunye nokusetyenziswa kwe-FRP rebar:
Ukuxhathisa ukonakala:
Enye yezona zinto ziluncedo kwi-FRP rebar kukumelana kwayo nomhlwa. Ngokungafaniyo nentsimbi, enokuthi ihlasele i-rust kunye ne-corrosion xa ibonakaliswe kumswakama, i-FRP rebar ayidli. Oku kwenza kube yinto efanelekileyo kwizakhiwo kwiindawo zaselwandle, iindawo eziselunxwemeni kunye neendawo ezinomswakama ophezulu.
Amandla aphezulu, Khaphukhaphu:
I-rebar ye-FRP inomlinganiselo ophezulu wamandla ukuya kubunzima, oku kuthetha ukuba inobunzima obungaphantsi kwentsimbi ngelixa igcina amandla afanayo okanye amakhulu. Oku kwenza ukuthumela, ukuphatha kunye nokufakwa lula. Ngaphandle kobunzima bayo obulula, i-rebar ye-FRP inamandla amakhulu okuqina.
Ayiqhubeki:
I-FRP rebar ayiqhubeki, oku kuthetha ukuba ayiqhubi umbane. Le propati yenza ukuba ifaneleke ukusetyenziswa kwizakhiwo ezifana neebhulorho kunye nokufakelwa kombane, apho ubukho bezinto zokuqhuba bungabangela ingozi yokhuseleko.
Ukuqina:
I-rebar ye-FRP inobomi obude benkonzo ngenxa yokuchasana nezinto ezahlukeneyo zokusingqongileyo. Ayichatshazelwa yimitha ye-UV, ukuguquguquka kobushushu okanye imijikelo yokunyibilika komkhenkce. Ezi propati zenza i-FRP rebar ifanelekele iiprojekthi zeziseko zophuhliso apho ukuqina kuyimfuno ephambili.
Non-magnetic kwaye non-conductive:
I-rebar ye-FRP i-non-magnetic kwaye i-non-conductive, iyenza ibe yinto efanelekileyo kwiindawo ezinobuthathaka apho ukuphazamiseka kwe-electromagnetic kufuneka kuncitshiswe, njengezibhedlele, izibonelelo ze-MRI kunye namaziko edatha.
Ukusetyenziswa kweentsimbi zentsimbi ze-FRP ziquka:
Izibonelelo zoluntu:
FRP rebarzisetyenziselwa ukwakhiwa kweebhulorho, iindlela ezinkulu, iitonela kunye nezakhiwo zokupaka ukuqinisa ikhonkrithi kunye nokuqinisekisa ukuhlala ixesha elide kwiimeko ezinzima zokusingqongileyo.
Ulwakhiwo lwaseLwandle:
I-FRP rebars isetyenziswa ngokubanzi kwizakhiwo zaselwandle ezinje ngamazibuko, amazibuko, iidokhi kunye nezakhiwo ezingasemanzini apho ukuvezwa kwamanzi anetyuwa, ukufuma kunye nezinto ezidlekayo ziphezulu.
Ulwakhiwo:
I-FRP rebar isetyenziswa ngakumbi kwizakhiwo zokuhlala kunye nezorhwebo ukuqinisa izakhiwo zekhonkrithi ezifana ne-slabs, iintsika, iindonga kunye neziseko.
Ukulungiswa koLwakhiwo:
I-rebar ye-FRP isetyenziselwa ukulungisa kunye nokomeleza izakhiwo ezikhoyo ezithwaxwa yi-corrosion okanye zifuna ukuqiniswa okongeziweyo.
Iindawo zokucocwa kwamanzi amdaka:
I-FRP rebars isetyenziswa ngokubanzi kwizityalo zokucocwa kwamanzi amdaka ezivezwe kwizinto ezinobumuncu kunye nezonakalisayo.
Izicelo zobuNgcali:
I-FRP rebars ingasetyenziselwa kwizicelo zobuchwephesha ezifana nokufakelwa kombane, izibhedlele, izibonelelo ze-MRI kunye namaziko edatha ngenxa yezakhiwo zabo ezingenamagnetic kunye ne-non-conductive.
Ngokubanzi, i-rebar ye-FRP ibonelela ngeenzuzo ezininzi, kubandakanya ukuxhathisa umhlwa, amandla aphezulu, ukuqina, kunye nepropathi engasebenziyo, iyenza ibe sisisombululo esiguquguqukayo nesisebenzayo kwiimfuno ezahlukeneyo zokwakha.
KUTHENI UKHETHA FRP REBAR
Isigqibo sokukhetha i-rebar ye-FRP sifuna ukuqwalaselwa ngenyameko kwizinto ezifana nomgangatho, ukusebenza kunye neendleko. Ukukhetha ulungelelwaniso phakathi kwezi zintlukwano kubalulekile xa usenza ukhetho olunolwazi. Ngelishwa, abantu bahlala bebeka phambili izibonelelo ezikhawulezayo ngeendleko zeenzuzo zexesha elide ezinokuzuzwa. Ukuba sithatha iindlela ezimfutshane namhlanje kwaye sityeshela isicwangciso esifanelekileyo, ngokuqinisekileyo siya kuchitha imali eninzi ekudilizeni okuphindaphindiweyo kunye nokwakhiwa kwakhona kwixesha elizayo. Nangona iindleko zokuqala ze-FRP rebar zithande ukuba phezulu,iinzuzo zeendleko zexesha elide ukuqina kwayo kunye nokugcinwa okuncitshisiweyo kodlula kakhulu utyalo-mali lokuqala. Ukucwangcisa uxanduva ngoku kubaluleke kakhulu, kubandakanywa nokuvavanya ngononophelo uqikelelo lobomi benkonzo, into ebalulekileyo kubunjineli bexabiso elide elide. Ukwakha iziseko ezingundoqo zelizwe lethu kunye nokwakha amakhaya ahlala ixesha elide kufuna ukusetyenziswa kwezinto ezikumgangatho ophezulu, ezifanelekileyo.
Xa uqwalasela unyawo lwakho lwekhabhoni, kubalulekile ukuba uqaphele ukuba ukuveliswa kwentsimbi kunempembelelo enkulu kakhulu yokusingqongileyo kunokuveliswa kwe-fiberglass rebar. Oku kuyinyani nangaphandle kokuthathela ingqalelo i-carbon footprint eyongezelelweyo eyenziwe ngokudilizwa ngokuphindaphindiweyo kunye nokubuyiselwa.
Ngokuthatha indlela yokujonga phambili kunye nokuqwalasela izibonelelo ezinokuthi zivele kwixesha elizayo, sinokuqinisekisa ukuba izenzo zethu zikhokelela kwiziphumo ezizinzileyo nezihlala zihleli.
