Cov ntaub ntawv raws li cov qauv saum toj ntawm qhov qhib, pom kev thauj khoom los ntawm cov phab ntsa thiab qab nthab, tau tshwm sim ntev dhau los, thaum tib neeg pib tsim cov pob zeb pej xeem cov tsev thiab vaj tse.
keeb kwm me ntsis
Feem ntau ntawm cov lintels saum toj no qhib tau arched, raws li lub sab sauv semicircular contour ntawm lub qhov rais me ntsis tsis muaj zog load. Lawv tau ua los ntawm cov pob zeb loj. Cov pob zeb no tau ua tib zoo hewn, kho rau ib leeg, kev ua haujlwm zoo li no yuav tsum muaj kev nqis peev tseem ceeb ntawm lub sijhawm thiab kev rau siab.
Kev tsim vaj tsev tau mus ntev, qhov tsis raug me ntsis hauv kev teeb tsa cov pob zeb lintel, tshwj xeeb tshaj yog lub hauv paus, lub tsev fuabtais, tuaj yeem ua rau muaj kev cuam tshuam thiab kev puas tsuaj ntawm cov qauv. Tab sis thaum lub tsev zoo kawg nkaus tau tsim, nws lub neej raug xam nyob rau hauv ib-paus xyoo.
Nrog rau qhov tshwm sim ntawm cib ua khoom siv hauv tsev, lintels tseem arched thaum xub thawj. Tab sis nws tau yooj yim dua rau kev ua haujlwm, txij li cov cib yog qhov loj tib yam, thiab thaum npaj lub jumper, nws muaj peev xwm ua seams ntawm txawv thicknesses, vim hais tias qhov xav tau qhib vojvoog tau tiav
Slab reinforced pob zeb lintels
Thaum neeg ua tsev los ntawm ntoo, ib lub lintel hla lub qhov rais los yoglub qhov rooj yog ib lub log tuab sib tshooj lub qhov rais nrog ntau chav.
Nrog rau kev txhim kho ntawm kev tshawb fawb, thev naus laus zis, kev tshawb pom ntawm cov thev naus laus zis tshiab hauv kev tsim kho, tshwj xeeb nrog kev qhia txog cov pob zeb ua kom muaj zog, cov pob zeb ua pob zeb tau tshwm sim. Cov jumpers no muaj cov duab plaub, lawv qhov dav tsis ntau tshaj 250 mm. Lawv yog npaj rau kev thaiv cov qhov qhib hauv cov phab ntsa cib ntawm cov tsev nyob thiab cov tsev pej xeem. Cov khoom no yog tsim nyob rau hauv series 1.038.1- 1.
Daim duab saum toj no qhia tau hais tias bar lintels. Ntxiv rau qhov bar, slab, beam, facade lintels thiab girders yog tsim. Tag nrho cov ntawm lawv yog fireproof lug.
Jumper marks
Tag nrho cov npe jumper muaj tsib pawg ntawm cov lej thiab cov tsiaj ntawv. Piv txwv, jumper 2 PB 19-3-p.
- 2 txhais tau tias tus lej hla;
- PB stands rau lub npe - bar lintel;
- 19 - qhov ntev ntawm cov khoom hauv decimeter;
- 3 - tsim load hauv kN/m (kgf/m);
- p txhais tau tias mounting loops.
thawj tus lej hauv qhov cim, ntawm 1 txog 5, qhia qhov ntev ntawm ntu ntu ntawm cov khoom.
Cov kab ntawv kab ntawv, nyob rau hauv lub npe ntawm tus lej thawj yog 1, nrog qhov ntev ntawm 120x65 (qhov siab) mm, tuaj yeem thaiv qhov qhib hauv qhov tsis yog cov kabmob cib partitions 120 mm tuab.
Yog thawj tus lej yog 2, ces qhov ntev ntawm qhov hla yuav yog 120x140 (qhov siab) hli. Cov lintels no tuaj yeem tiv taus qhov hnyav txog 400 kgf / m thiab siv rau hauv cov phab ntsa txhawb nqa tus kheej. Yog thawj tus lej yog 3, ces qhov ntev ntawm qhov sib txawv yuav yog 120x220.(qhov siab) mm. Cov jumpers no tau txhawb nqa, lawv tiv taus lub nra ntawm qhov sib tshooj.
Txhua lub lintel muaj qee qhov tob ntawm cov kabmob ntawm phab ntsa, nyob ntawm nws lub peev xwm bearing. Yog hais tias lub load ntawm lub jumper tsis tshaj 400 kgf / m, ces qhov kev txhawb nqa qhov tob yuav yog 120 hli, yog hais tias lub load yog ntau tshaj 400 kgf / m, ces qhov kev pab cuam qhov tob yuav yog los ntawm 170 hli mus rau 230 hli.
Yuav kom xaiv lub jumper txoj cai, koj yuav tsum paub qhov dav ntawm qhov qhib kom npog, lub thickness ntawm phab ntsa qhov chaw qhib, thiab seb lub qab nthab nyob ntawm nws.
Nyob ntawm qhov tuab ntawm phab ntsa, ob lossis peb lub pob zeb tau muab tso rau saum qhov qhib, thiab ib qho ntxiv yog muab tso rau ntawm lub qab nthab.
Txoj kev thauj mus los thiab kev teeb tsa
Qee zaum, tshwj xeeb tshaj yog ua ntej kev thauj mus los, nws yog ib qho tsim nyog los xam qhov ntim ntawm cov kab hauv qab. Thaum xam, nws yuav tsum raug coj mus rau hauv tus account tias cov pawg thauj khoom yuav tsum muaj qhov siab tsis tshaj 2 m, thiab txhua tus jumper yuav tsum tau muab tso rau ntawm ob lub qhov rooj ntoo. Lub dav hlau sab saum toj ntawm lub lintel yuav tsum yaug nrog rau sab saum toj ntawm lub masonry.
Cov lintels yog ntsia rau ntawm ib txheej ntawm M100 cement-xuab zeb mortar. Cov lintel, nyob rau ntawm ntug sab nrauv ntawm phab ntsa, yog ntsia 65 hli hauv qab ntawm lwm tus, tsim ib lub quarter, tsim nyog thaum txhim kho qhov rais kom cua tsis txhob tuaj rau lawv.
