Ukwandiswa joint: Oku kuthintela uhlaba isakhiwo

Ukutshintsha kwamaqondo obushushu, ukufuma, umoya, imithwalo obuluqilima jikelele kunye neenyikima - izinto ezidla kukhokelela deformation eso sakhiwo. Ukutshintsha ivolyum yokwakha izinto (ukwanda okanye ukurhwaqela ngenxa umahluko lobushushu), okanye ukutshona iziqalelo (ngenxa iimpazamo ekubalweni isiseko okanye umhlaba ukuthembeka zaneleyo) akuzange kubangele ekutshatyalalisweni isakhiwo liphela, kungakuhle ukuba ukusebenzisa joint ukwanda.

Types of amalunga ukwanda

Kuxhomekeke kuhlobo yothintelo lwe deformation beentanda kuyimfuneko ukwahlula ubushushu, shrinkage, antiseismic kusombiwa.

Thermal ukwanda joint isetyenziselwa ukuthintela utshintsho tye. Xa kubalwa i industrial isakhiwo ngokubiyela scheme yoyilo beentanda kufuneka ungabi ngaphantsi kwe 60 m ukuya kuma-40 m kwaye ndinobushushu izakhiwo okulala. Ngokuqhelekileyo, ukwanda amalungu ziquka ubume ephakamileyo kuphela, ngoxa isiseko ixhomekeke kangako umahluko lobushushu.

Intlenge ukwanda joint kuyimfuneko ukuze aphephe inkangeleko iintanda amacandelo zezakhiwo ngenxa yokuba umthwalo isasazwa edyokhweni okanye imihlaba abahluphekayo ezinye iziqalelo kuthotha. Ngokungafaniyo ingenamthungo thermal esahlula yodaka nesiseko.

ukwanda amalungu Anti-yenyikima kwizakhiwo zibekwe kummandla nokonyuka ziintshukumo zenyikima, phantse kuyimfuneko. Ngeendleko zabo isakhiwo zahlulwe phakathi zaziibloko, eyona elizimeleyo omnye komnye, ngoko kwimeko yentshabalalo inyikima okanye deformation yeyunithi omnye akayi kuchaphazela nabanye.

Ukuba design sakho iquka a iindonga monolithic eziphathekayo, sofinyela ukwanda joint iyafuneka. Inyaniso kukuba lo eziphathekayo lidla ukuba sofinyela, zinciphise ubukhulu - oko kukuthi, udonga, ahlambe ngqo esakhiweni, kunokuba ndawonye ukusuka panels eziphathekayo, ngokuqinisekileyo ziya kuncitshiswa kulo mqulu, ekudaleni abana. Kuba lula umsebenzi ngakumbi yenziwe nciphisa edityanelweyo phambi bathele udonga elandelayo, kwaye emva kokuba eziphathekayo owomileyo, natywinwa beentanda kunye izikhewu.

Uphawu kunye nokuthintela ubushushu amalungu

Lo mba ubaluleke kakhulu ukunikela ingqalelo kakhulu eku: amalungu kufuneka zikhuselwe kakuhle kwimpembelelo yangaphandle. Ukulungiselela le njongo, iintlobo ezahlukeneyo yokwambathisa lokufaka. Lyu okanye epoxy yokuncamathelisa - okunye okuhle, babe lukhuni eliphezulu kwaye nezimo kakhulu; enye indlela - Sebenzisa polyethylene amagwebu Intambo elandelayo kweConvenco sealant. Enye indlela - ukugcwaliswa ukwanda ngokudibeneyo bezimbiwa yoboya. Ilunga movement eludongeni ezaliswe uboya ezimbiwa, kuyimfuneko ukuvala ubunzima elastic leyo iyamelana yemozulu kwaye ikhusela isikhombisi ukusuka ukufuma kunye ngamathontsi. Ngaphandle fillers, omhlophe ibe ukhuselwe yabucala okanye umtya ubungakanani efanelekileyo.

Amacala beentanda

Ububanzi namalungu yahluka ukusuka cm 0.3 ukuya kwi-100, kuxhomekeka kuhlobo joint, kwakunye nemiqathango yokusebenza ye kwesakhiwo. Amalunga Ukwandiswa ukufikelela 4 cm (emxinwa), kunye shrinkage ukulinganisela (4-10 cm) ububanzi (10-100 cm).
