Yintoni i-expansion joint ibuzwa rhoqo kwishishini lokwakha, nangona ingaqhelekanga ukubonwa kubomi bemihla ngemihla. I-expansion joint, eligama elinikwa izikhewu ezicwangcisiweyo kwiiprojekthi zokwakha, isetyenziswa ngakumbi ngexesha lokwakhiwa kwezakhiwo eziphakamileyo nezinkulu.

Namhlanje, iindlela ezahlukeneyo zisetyenziswa kwaye zisetyenziswa ekwakheni izakhiwo. Enye yazo yi-expansion joint. Kwinqaku lethu elilungiselelwe nguUBaumerk, ingcali yeekhemikhali zokwakha, siza kunika iimpendulo ezineenkcukacha kwimibuzo yokuba yintoni i-expansion joint, kwiindawo eziphi, kwaye zeziphi iindlela esetyenziswa ngazo.

Ukongeza, ukuze ufumane ulwazi oluneenkcukacha malunga nokunamathela, enye yezona ngongoma zibalulekileyo zokwakha iiprojekthi, ungajonga umxholo wethu onesihloko esithiYintoni i-Adherence? Kutheni kubalulekile ukuyisebenzisa i-Adherence Increser?

Yintoni i-Expansion Joint?

Umbuzo wokuba yintoni i-expansion joint ungaphendulwa ngokulula njengocwangciso lwangaphambi kokuba kubekho izithuba ezishiywe ngabom kwicandelo lokwakha. Kutheni ke le miba ishiywa ngabom xa kusakhiwa? Le miba ishiywa ngokuchasene nokuguquguquka okunokwenzeka ngenxa yezinto ezifana nomahluko womhlaba apho kubekwa khona izakhiwo eziphakamileyo nezinkulu zokuhlala, amaqondo obushushu aguquguqukayo, imithwalo engashukumiyo eza kwenziwa zizinto ezithe tye okanye ezithe nkqo eziza kubekwa phezu kwayo, ukuhamba kwezinto ezinje ngokwandiswa, ukuncitshiswa, ukufinyela, kunye nokungachaphazeleki kangako ziinyikima.

I-expansion joint kukuzaliswa kwezi zikhewu ngezinto ezifanelekileyo. Kukho izinto ezininzi ezisetyenziswayo ngexesha lokwakha kwaye utshintsho lobushushu bezinto zahlukile. Ke ngoko, ukuthamba, ukushwabana, kunye nokuziphatha kokwandiswa kwento nganye kwahlukile. Ngenxa yesi sizathu, ezi zikhewu zokwandiswa ngabom ezishiywe kwizakhiwo zibalulekile kwaye zibaluleke kakhulu kwingqibelelo engaguqukiyo yolwakhiwo. Ezi zikhewu emva koko zivalwa ngeeprofayili zokwandiswa ezifanelekileyo. Ukuqina kwezakhiwo kuyanda ngenxa yeeprofayili zokwandiswa kwento, ezithintela umonakalo womzimba kwaye zincede ukuvala izikhewu ngeyona ndlela ilungileyo.

Nangona izakhiwo zihlala zakhiwa kusetyenziswa izinto eziguquguqukayo, ukusetyenziswa kweprofayili yokudibanisa yokwandisa kuyimfuneko xa ubungakanani besicwangciso bukhulu. Ekubeni kukho izinto ezininzi eziguquguqukayo ezifana namaqondo obushushu angaphakathi ngexesha lokwakhiwa kunye nobubanzi bobushushu obulindelekileyo ngexesha lobomi besakhiwo, amaxesha okwandisa kunye nokunciphisa kufuneka acwangciswe ngokufanelekileyo kwiiprojekthi, kwaye izikhewu zokudibanisa zokwandisa kufuneka ziyilwe ngokweenkcukacha ngobunjineli kunye neziseko zobugcisa.

Kutheni i-Expansion Joint ifuneka?

Ngoku ekubeni siphendule umbuzo wokuba yintoni i-expansion joint, singathetha ngesizathu sokuba ifuneka. Xa sicinga ukuba izakhiwo zakhiwe kwindawo enkulu yokuhlala, sikhankanye ukuba ukusebenzisana komgangatho kunye nesixhobo ngasinye sawo kunye nobushushu kwahlukile. Ekubeni izithuba ezakhiwe kule ndawo inkulu yokuhlala zahlula isakhiwo zibe ngamacandelo ahlukeneyo, kuvumela ukuba izinto kunye nomphezulu ezisebenzisana nawo zichaphazeleke ngokwahlukileyo kwiindlela zokuziphatha ezifana nokwandisa, ukuxinana, kunye nokungcangcazela, ngaloo ndlela zenza isakhiwo sibe namandla ngakumbi.

Ngenxa yesi sizathu, izikhewu zokwandisa amalunga, ezikwabizwa ngokuba ngamalunga okwandisa, zibaluleke kakhulu kumandla angashukumiyo esakhiwo. Ekubeni amalunga okwandisa ahlula izakhiwo zibe ngamacandelo ahlukeneyo athe tye nathe nkqo ukusuka kwisiseko ukuya eluphahleni, into nganye ifumana inkululeko yokuhamba kwindawo yayo ngokuchasene nemiphumo yobushushu, ukungcangcazela, kunye nokunyikima komhlaba, ukuze ukwaphuka okunokwenzeka kunciphe. Ngaloo ndlela, isakhiwo siphela siba sikhuselekile kwaye somelele ngakumbi.

Amacandelo okwandisa ajolise ekunciphiseni iintanda ezinokwenzeka kwisakhiwo ngenxa yokuhlaliswa komhlaba, ukwanda kunye nokuxinana kobushushu, ukungcangcazela, kunye nemiphumo yokunyikima komhlaba.

Iimpawu ze-Expansion Joints

Amalungu okwandisa avumela ukufinyela nokwandisa ubushushu ngaphandle kokubangela uxinzelelo ngaphakathi kwesakhiwo. Amalungu okwandisa ayilwe ukuze afunxe ngokukhuselekileyo ukwandiswa nokuncipha kwezinto ezahlukeneyo zokwakha, afunxe ukungcangcazela, kwaye avumele isakhiwo ukuba silungelelanise ngokufanelekileyo iintshukumo zomhlaba ezibangelwa ziinyikima.

Iijoyinti ezivulekayo zifumaneka kwizakhiwo kunye naphakathi kwee-intersection zeebhulorho, iipavumente, imizila kaloliwe, kunye neenkqubo zemibhobho. Iijoyinti ezivulekayo zibandakanyiwe ukumelana noxinzelelo. Ijoyinti evulekayo luqhagamshelo nje phakathi kwamacandelo ezinto ezifanayo. Ekwakhiweni kweebhloko zekhonkrithi, iijoyinti ezivulekayo zibizwa ngokuba ziijoyinti zolawulo. Iimpawu ezibaluleke kakhulu zezinto ezisetyenziselwa ukukhulisa zezi zilandelayo:

• Ifunxa ukwanda kunye nokucutheka kwezinto zokwakha ezibangelwa bubushushu.
• Ifunxa ukungcangcazela.
• Igcina iindawo zihlangene.
• Inciphisa umonakalo ngokuvumela intshukumo ebangelwa ziinyikima zomhlaba.

Iintlobo zeeJoints zoKwandisa

Ukuvala iindawo zokwandisa ukuze kuthintelwe amanzi kwenziwa ngeeteyipu zokwandisa iindawo zokudibanisa. Ezi zinto zingasetyenziswa ngokukhuselekileyo kwiindawo ezahlukeneyo zokusetyenziswa, ukusuka kwisiseko ukuya eluphahleni, phakathi kweebhloko zokwakha, iindonga ezigcina amanzi, kwimigangatho eya kuvezwa yimithwalo enzima, iibhulorho kunye nee-viaducts, kwanakwiindawo ezininzi ezahlukeneyo zokusetyenziswa ezifana nokudibana kweendawo ezimbini ezahlukeneyo zokusetyenziswa.

Iteyiphu yokuKhulisa esekwe kwi-TPE, esekwe kwi-Elastic - i-TPE FLEXKwikhathalogu yemveliso yeBaumerk isetyenziswa njengeteyiphu yokwandisa ethambileyo kakhulu yokuvala izikhewu zokwandisa, amalungu okwandisa ubushushu, kunye nemingxunya. I-TPE FLEX, esetyenziswa ekukhuliseni ngokuthe nkqo nathe tye kuzo zonke izakhiwo, iziseko, amakhethini, iindawo ezingaphantsi komhlaba, unyango lwamanzi amdaka, amanzi okusela, amatanki amanzi, amachibi, iitonela kunye nee-culverts, ikhethini yerafu, amaqabane abandayo okukhusela amanzi, ahlukile ngokumelana kwayo ne-UV kunye nokusebenza okuphezulu kumanqanaba obushushu abanzi.

Uyisebenzisa njani iTape yoKwandisa iJoint?

Okokuqala, umphezulu wokufaka kufuneka wome kwaye ucoceke, ungabi naoyile, uthuli, umhlwa, kunye nokungcola. Iintanda kumphezulu wokufaka kufuneka zizaliswe ngodaka lokulungisa. Emva koko i-epoxy adhesive ifakwa kuwo wonke umgangatho ububanzi obuyi-40/50 mm kunye nobukhulu obuyi-1/1.5 mm.

Ngokwemigangatho eza kusetyenziswa, iteyiphu yokwandisa inqunyulwa ibe nobude obufanelekileyo kwaye iteyiphu inamathele ngokucinezela ngamandla aphezulu. Emva koko, emva kokuba umaleko wokuqala we-epoxy adhesive uqine kancinci, i-1/1,5mm ubukhulu iyafakwa kwakhona. Okwangoku, kufuneka kuqinisekiswe ukuba i-epoxy adhesive ayinamatheli kwiteyiphu yokwandisa kwaye akukho kulahleka kokuqina. I-epoxy adhesive emaphethelweni eteyiphu yokwandisa ifanele ingashukunyiswa ide iqine ngokupheleleyo kwaye kufuneka ikhuselwe emanzini nakwezinye iimpembelelo zoomatshini.
