Izihlanganisi zokwandisa irabha zidlala indima ebalulekileyo kwizicelo ezininzi zoshishino ezifuna ukuguquguquka kunye nokuhamba kweenkqubo zemibhobho. Zisetyenziswa kakhulu ukuhlawula ukwanda kobushushu, ukungcangcazela kunye nokungahambi kakuhle, ukuqinisekisa ukusebenza kakuhle kunye nokuthintela umonakalo kwiinkqubo zemibhobho. Nangona kunjalo, ukukhetha isihlanganisi sokwandisa irabha esifanelekileyo kwisicelo sakho esithile kubalulekile ukuqinisekisa ukusebenza kwayo okuphezulu kunye nobomi benkonzo. Kweli nqaku, sixoxa ngezinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha isihlanganisi sokwandisa irabha.

1. Ubushushu kunye noxinzelelo
Enye yezinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha i-raber expansion joint kubushushu kunye neemeko zoxinzelelo eziya kumelana nazo. I-raber expansion joints zenzelwe ukumelana nobushushu kunye noxinzelelo oluhlukeneyo. Ke ngoko, kubalulekile ukwazi ubushushu kunye noxinzelelo oluphezulu noluncinci oluya kudibana nalo i-joint ukuze kuqinisekiswe ukuba ilinganiswe ngokufanelekileyo. Ukungaphumeleli ukukhetha i-rating echanekileyo kunokubangela ukungasebenzi kakuhle kwe-joint kunye nomonakalo onokwenzeka kuyo yonke inkqubo.

2. Iimfuno zesenzo
Izihlanganisi zokwandisa irabha zivumela intshukumo ye-axial kunye ne-lateral kwiinkqubo zemibhobho. Ngaphambi kokukhetha i-joint yokwandisa irabha, kubalulekile ukumisela intshukumo elindelekileyo kunye nokufuduka okuza kwenzeka kwinkqubo. Oku kuquka izinto ezifana nokujikeleza kwe-angular, ucinezelo lwe-axial kunye nokuphambuka kwe-lateral. Ngokuvavanya ngokuchanekileyo iimfuno zentshukumo, ungakhetha izihlanganisi ezifunxa ngokwaneleyo kwaye zihlawulele intshukumo elindelekileyo, ukuthintela uxinzelelo kwinkqubo yakho yemibhobho.

3. Ukuhambelana okuphakathi
Izihlanganisi zerabha zenziwe ngezinto ezahlukeneyo ezinokuchasana kweekhemikhali ezahlukeneyo. Kubalulekile ukuqwalasela imidiya ehamba kwi-expansion joint kwaye uqinisekise ukuba iyahambelana nezinto zerabha. Iikhemikhali ezithile okanye ulwelo zingonakalisa ezinye iintlobo zerabha, nto leyo ebangela ukungasebenzi kakuhle kwangethuba. Ukwazi ukwakheka kweekhemikhali ze-medium nokukhetha izinto zerabha ezingamelaniyo nezenzo ezinokwenzeka zokubola kubalulekile kwixesha elide kunye nokuthembeka kwe-expansion joint.

4. Ulwakhiwo kunye nokuqinisa
Usetyenziso olwahlukeneyo lufuna ulwakhiwo olwahlukeneyo lwe-raber expansion joints kunye neentlobo zokuqinisa. Zingaba zii-single-arch okanye multi-arch designs, nganye inikezela ngamanqanaba ahlukeneyo okufunxa intshukumo kunye nokuguquguquka. Ukukhetha izinto zokuqinisa (ezifana nelaphu okanye isinyithi) kufuneka kusekelwe kwiimfuno ezithile zokusetyenziswa. Amalungu aqiniswe ngelaphu afanelekile kwiingcinezelo eziphantsi kunye neentshukumo ezithambileyo, ngelixa amalunga aqiniswe ngelaphu angcono kwiingcinezelo eziphezulu kunye neentshukumo ezinkulu.

5. Umgangatho kunye nesatifikethi
Xa ukhetha ijoyinti yokwandisa irabha, kubalulekile ukuqwalasela udumo lomenzi, amava kunye nemigangatho yomgangatho. Ukukhetha umenzi othembekileyo kuqinisekisa ukuba ufumana imveliso ehlangabezana nemigangatho yoshishino kwaye iye yavavanywa ngokuqatha. Isiqinisekiso esivela kwimibutho eyaziwayo efana ne-ISO okanye i-ASTM sibonelela ngesiqinisekiso esongezelelekileyo somgangatho kunye nokusebenza kwejoyinti yokwandisa irabha.

Ukuqukumbela, ukukhetha i-raber expansion joint efanelekileyo kufuna uvavanyo olucokisekileyo lweemfuno zobushushu kunye noxinzelelo, ulindelo lokuhamba, ukuhambelana kwemidiya, ulwakhiwo, ukuqina kunye nodumo lomenzi. Ngokuqwalasela ezi zinto, ungakhetha i-raber expansion joint ehlangabezana neemfuno zakho ezithile, ukuqinisekisa ukusebenza okuthembekileyo nokusebenzayo kwenkqubo yakho yemibhobho.
