Nyob rau hauv niaj hnub architecture, kev siv tus nqi ntawm pem teb bearing phaj yog siab dua thiab siab dua. Nrog rau cov qauv steel ntawm lub tsev ntawm cov plag tsev sib txawv, ntau tus kuj siv cov slabs hauv pem teb los ua. Kuv ntseeg hais tias ntau tus neeg muas zaub sab laj: yuav ua li cas tuab cement thickness ntawm lub rooj tsavxwm? Hnub no, cia's muaj lus zoo txog qhov teeb meem no.
Raws li ib tug ruaj khov daim ntawv ntawm lub tsev, nws load coefficient yog lub hauv paus ntawm kev tsim thiab kev tsim kho. Yog li ntawd, nyob rau hauv feem ntau ntawm kev ntsuas thiab kev tsim kho, lub thickness ntawm cov cement nteg feem ntau yog hais txog 120mm, uas yog raws li cov thickness ntawm hauv pem teb ntawm tsoos steel pob zeb qauv. Tau kawg, peb tsis txiav txim siab tshwj xeeb hauv qee qhov haujlwm tshwj xeeb. Piv txwv li, lub thickness ntawm pem teb yog thicker; Ib lub tsev ntau - tsev ntawm ob lossis peb lub tsev; Yuav tsum tau muab cov khoom siv cog qoob loo ntau, cov load rau hauv pem teb loj dua. Tseem muaj qee qhov kev cob qhia ntau lawm, thaum lub tshuab yuav tsim kev vibration load. Raws li cov kev xav tau tshwj xeeb no, cov cement thickness feem ntau yog teem rau ntawm 150mm, thiab qee zaum txawm mus txog 200mm.
Tsis tas li ntawd, kev xaiv ntawm pem teb slab thickness kuj cuam tshuam los ntawm ntau yam. Piv txwv li: nyob rau hauv cov ntaub ntawv ntawm hluav taws tsis kam txwv ntawm 1.5 teev, lub thickness ntawm lub hauv pem teb kuj raug cuam tshuam.
Ua ntej ntawm tag nrho cov, pem teb bearing phaj nyob rau hauv lub steel qauv tsev yuav tsum ncav cuag qhov hluav taws kub tsis kam ntawm 1.5 teev, thiab peb pawg ntawm qhib phaj, shrinkage phaj thiab kaw phaj yuav xaiv tau. Hauv qhov tshwj xeeb, cov cement nteg yuav tsum yog 80 hli siab tshaj qhov saum npoo ntawm lub phaj qhib, thiab hauv pem teb yuav tsum tau nruab nrog lub hauv qab qhov cuab lub zog ntawm lub phaj.
Qhov thib ob, lwm yam yog hluav taws kub retardant txheej. Hauv qab ntawm lub phaj qhib hauv pem teb yuav tsum txhuam cov hluav taws kub retardant txheej, txheej thickness ≥15, kom cov cement tsuav raws li cov txheej txheem yuav tsum tau, 50 hli siab tshaj qhov siab ntawm cov tav tuaj yeem ua tau.
