Yuav Ua Li Cas Ntsuam Xyuas Qhov cuam tshuam ntawm Terrazzo Prefabricated Panels? Puas yuav rub cov khoom hnyav ua rau tawg hauv Terrazzo Prefabricated Panels?

Kev sim txoj kev rau kev cuam tshuam ntawm terrazzo prefabricated panels thiab kev tsom xam ntawm kev cuam tshuam ntawm cov khoom hnyav luag
1, Kev sim txoj kev rau kev cuam tshuam kev ua haujlwm
Qhov cuam tshuam tsis zoo ntawm terrazzo prefabricated panels yuav tsum tau soj ntsuam los ntawm cov qauv kev sim, nrog rau cov khoom kuaj tseem ceeb xws li lub zog flexural, compressive zog, thiab kev cuam tshuam kev simulation. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:

Bending zog kuaj
Cov qauv xeem: Raws li qhov yuav tsum tau ua ntawm "Kev Sib Sau ntawm Cov Khoom Siv Hauv Tsev", siv cov qauv txiav rau hauv 150mm × 100mm, nrog rau qhov nruab nrab ntawm 100mm ntawm kev txhawb nqa cylinders, thiab uniformly thauj cov qauv ntawm qhov ceev ntawm 30-50N / s kom txog thaum lawv tawg.
Kev txiav txim siab: Lub zog flexural yuav tsum tau ua kom tau raws li cov qauv tsim (feem ntau Ntau dua lossis sib npaug rau 10MPa), thiab qhov tsawg kawg nkaus tus nqi ntawm ib qho thaiv yuav tsum tsis pub tsawg dua 80% ntawm cov lej lej. Qhov saum npoo hardness ntawm siab - lub zog terrazzo tuaj yeem ncav cuag 6-8 qib, thiab nws tuaj yeem tiv taus hnyav dov yam tsis muaj tawg.
Compressive zog test
Kev sim txoj kev: Siv lub tshuab ntsuas siab los siv lub nra rau cov qauv qauv (xws li 100mm × 100mm lub voos xwmfab), sau cov load tsis ua haujlwm, thiab suav lub zog compressive.
Cov ntaub ntawv siv: Lub zog compressive ntawm siab- zoo terrazzo tuaj yeem ncav cuag 30-50MPa, ntau dua li cov pob zeb zoo tib yam (20-30MPa), ua kom nws muaj peev xwm tiv taus cov kab ntsug.
Dynamic impact simulation (yeem)
Kev sim poob rauj: Simulate qhov cuam tshuam ntawm cov khoom hnyav poob, thiab sim ntsuas qhov kev puas tsuaj rau ntawm lub rooj tsavxwm los ntawm kev kho qhov hnyav (xws li 50kg) thiab qhov siab (xws li 1m) ntawm qhov poob rauj.
Pendulum impact test: Ntsuas qhov toughness ntawm cov ntaub ntawv nyob rau hauv siab -kev cuam tshuam ceev, haum rau siab thov scenarios xws li industrial flooring.

2, Kev cuam tshuam ntawm cov khoom hnyav rub ntawm terrazzo prefabricated panels
Txawm hais tias rub cov khoom hnyav ua rau tawg yuav tsum muaj kev tsom xam ntawm cov khoom siv, kev tsim kho, thiab kev siv cov xwm txheej:

Khoom siv tau zoo
High hardness thiab hnav tsis kam: Lub hardness ntawm terrazzo nce mus txog 6-8 qib, nrog kev hnav zoo dua li cov vuas hauv pem teb, thiab tuaj yeem tiv taus kev sib txhuam ntawm cov khoom hnyav.
Crack resistance: Cov qauv kho terrazzo yog ntom, nrog qis shrinkage deformation tus nqi, thiab tsis yooj yim tawg vim muaj kev ntxhov siab hauv zos.
Muaj peev xwm tawg txaus ntshai thiab kev tiv thaiv kev tiv thaiv
Cov teeb meem hauv cov hauv paus hniav: Yog tias cov av rov qab ntawm cov hauv paus hauv paus tsis muaj zog, lub thickness ntawm lub cushion txheej tsis sib xws, los yog tsis muaj steel mesh tau teeb tsa, rub cov khoom hnyav yuav ua rau muaj kev cuam tshuam.
Kev Tiv Thaiv: Ua kom lub hauv paus txheej yog compacted txheej los ntawm txheej, lub thickness ntawm lub cushion txheej yog uniform (Ntau tshaj los yog sib npaug zos rau 50mm), thiab ob -txoj kev steel tuav (xws li Φ 6 @ 200mm) yog ntxiv nyob rau hauv loj cheeb tsam.
Kev tsim daim phiaj tsis tsim nyog: Cov kab sib tw me me yog qhov yooj yim rau kev tawg vim muaj kev ntxhov siab shrinkage.
Kev Tiv Thaiv: Qhov dav ntawm txoj kab sib faib yuav tsum yog 10-15mm, nrog qhov sib nrug tsis tshaj 6m, kom tsis txhob muaj qhov nqaim thiab elongated cheeb tsam.
Kev tsim kho tsis xws luag: Cov kav dej zais zais siab dhau lawm thiab cov mortar tsis ruaj ruaj, uas yuav ua rau muaj kev tawg hauv zos.
Kev Tiv Thaiv: Lub thickness ntawm cov txheej tiv thaiv nyob rau sab saum toj ntawm lub raj xa dej yuav tsum siab dua los yog sib npaug ntawm 20mm, thiab nws yuav tsum tau nchuav nruj nrog cov pob zeb zoo.
Kev txheeb xyuas qhov tseeb
Daim Ntawv Thov Chaw Nres Tsheb: Terrazzo flooring yog dav siv nyob rau hauv hnyav- cov xwm txheej xws li chaw nres tsheb thiab chaw thauj khoom vim nws qhov siab tawv thiab ua haujlwm rau dov, thiab tsis tau ntsib teeb meem tawg tom qab siv sijhawm ntev -.
Kev lag luam hauv pem teb: Hauv kev cob qhia kev tsim kho tshuab, terrazzo prefabricated panels tuaj yeem tiv taus ntau zaus los ntawm forklifts thiab tswj cov qauv kev ncaj ncees, ua pov thawj lawv cov kev cuam tshuam cuam tshuam.

3, Cov lus xaus thiab cov lus qhia
Kev cuam tshuam kev ua tau zoo: Terrazzo prefabricated panels tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm hnyav -cov haujlwm xwm txheej los ntawm kev khoov thiab kev ntsuas lub zog thiab kev sim ua kom muaj zog, thiab lawv cov kev cuam tshuam kev ua haujlwm zoo dua li cov vuas hauv pem teb thiab pob zeb.
Kev nyab xeeb ntawm cov khoom hnyav rub tawm: Raws li qhov chaw ntawm kev kho cov nyom kom zoo, tsim nyog daim phiaj tsim, thiab kev tsim kho tsis raug, kev thauj khoom hnyav yuav tsis ua rau tawg. Nws raug nquahu kom tsis tu ncua xyuas kev sib khi ntawm cov kab sib faib thiab kev sib haum xeeb ntawm cov txheej txheem kom ntev nws lub neej kev pab cuam.
Kev xaiv cov khoom siv thiab cov ntsiab lus ntawm kev tsim kho: Ua ntej xaiv qhov siab ci thiab siab hardness terrazzo prefabricated panels, thiab xyuas kom meej tias pab neeg tsim kho muaj kev tsim nyog, nruj me ntsis raws li "Code for Acceptance of Construction Quality of Building Ground Engineering" (GB50209) rau kev ua haujlwm.
