Dab tsi yog lintel hauv kev tsim kho? Txhais: qhov no yog ib qho qauv uas muab faib, los yog theej, yog nyob rau hauv kab rov tav thiab siv lub siab los ntawm saum toj no los ntawm phab ntsa lossis hauv pem teb slabs. Cov qauv zoo li no yog siv los tsim cov qauv monolithic, cov tsev ua vaj tse ntxiv, cov qauv cib, nrog rau cov qauv ua los ntawm cov pob zeb lossis cov khoom siv ntuj tsim. Cov pob zeb uas muaj zog ntxiv no muaj qhov qhib rau saum qhov rais thiab qhov rooj. Tsim cov plag tsev siv cov qauv uas siv lub nra.
Nyob ntawm jumpers
- Monolithic.
- Team.
thawj cov khoom tsim tawm ntawm qhov chaw tsim kho. Tom qab lub formwork raug ntsia, lub reinforcing mesh yog tsau, uas yog tom qab sau nrog cement qhob mortar. Prefabricated qhov chaw yog tsim nyob rau hauv ntau lawm thiab ces xa nyob rau hauv qhov yuav tsum tau kom muaj nuj nqis rau cov chaw tsim kho los ntawm tshwj xeeb tsheb.
Jumper classification
Muaj jumpers:
Squared type. Dav mus txog250 hli. Nws muaj PB cim
Slab. Dav ntau tshaj 250 mm. Muaj PP cim
Beam. Nws yog siv thaum txhawb los yog sib txuas qhov chaw ntawm hauv pem teb slab. Muaj GHG cim
Facade. Dab tsi yog façade lintel? Qhov no yog cov khoom siv los thaiv qhov qhib. Lub thickness ntawm phab ntsa nyob rau hauv lub qhov rais los yog lub qhov rooj qhib uas protrudes yuav yog los ntawm 250 millimeters los yog ntau tshaj. Nws yog cim PF
Production
Dab tsi yog jumper? Qhov no yog cov khoom tsim los ntawm cov pob zeb ua kom muaj zog, hauv kev tsim cov pob zeb hnyav thiab cov pob zeb ntxiv dag zog siv. Hom cement pob zeb sib tov thiab hom kev txhawb nqa lub tawb yog xaiv raws li qhov tsim nyog lub zog xav tau rau yav tom ntej cov khoom siv ntxiv dag zog. Kuj jumpers yog ua los ntawm cellular pob zeb. Lawv yog cov yam ntxwv ntawm lub ntiajteb txawj nqus, tsis tshua muaj thermal conductivity, uas tso cai rau koj tsis txhob txhawj txog kev rwb thaiv tsev ntxiv.
Lawv muaj ob hom kev txhawb nqa:
- ntawm kev ntxhov siab ntxiv;
- ntawm qhov tsis muaj kev ntxhov siab;
Nws raug kho tawm tsam lwm yam uas tuaj yeem cuam tshuam rau lub tawb ntxiv, xws li corrosion. Reinforced qhob cov khoom sib txawv hauv cov duab, xov tshuab thiab cov kabmob muaj peev xwm.
Siv lub yuag jumpers
Dab tsi yog aerated pob zeb lintel? Qhov no yog ib yam khoom uas, txawm tias nws qhov hnyav tshwj xeeb, tiv taus qhov tsim nyog compressive thiab tawg loads. Qhov no yog muab los ntawm kev txhawb zogqhov zoo ntawm aggregates thiab clarity ntawm lub tshuab ua raws li. Lub tshuab nqus tsev perceives compressive loads, thiab lub zog tensile. Aerated qhob khoom yog siv nyob rau hauv kev tsim kho ntawm cov qauv mus txog tsib plag tsev siab, vim hais tias lawv tsis muaj lub zog inherent nyob rau hauv cov khoom siv ntxiv dag zog.
Marking
Dab tsi yog jumper? Qhov no yog ib yam khoom uas cim nrog cov tsiaj ntawv thiab cov lej, piv txwv li, 3PB-33.16-3p. Cov lej hauv lub cim qhia qhov loj ntawm qhov hla ntu (ntev, dav, qhov siab) thiab qhov taw qhia uas qhia txog qhov ntsuas qhov hnyav rau cov khoom siv. Cov tsiaj ntawv qhia txog nws hom, thiab tsab ntawv kawg "P" (yog tias muaj) qhia tias muaj kev nqa lub voj voog.
Kev thauj mus los thiab khaws cia
Dab tsi yog lintels hauv kev tsim kho? Cov no yog cov khoom pabcuam uas tau yooj yim thauj kab rov tav hauv cov tsheb tshwj xeeb. Thaum thauj khoom, lawv tau ntim nruj rau ib leeg, thaum siv gaskets. Ua ntej ua tiav cov kab hauv qab ntawm cov jumpers, cov ntaub qhwv tau muab tso rau hauv perpendicularly. Feem ntau yog ua los ntawm cov ntoo, vim tias lawv muaj ntau dua li lwm cov ntaub ntawv uas muaj peev xwm faib cov hluav taws xob tau txais los ntawm cov jumpers. Thaum kawg ntawm kev tso cov jumpers, lawv tau tsau rau hauv lub tsheb thauj khoom, tawg tawm tsam cov npoo, yog tias lawv tsis tau muab tso rau hauv cov ntaub ntawv tshwj xeeb rau lawv. Thaum loading thiab unloading lub jumpers, load-kuav mechanisms thiab lifting khoom yog siv. Jumpers raug tshem tawm hauv cov blocks.
