Steel fibre ukhonkolo: izici, GOST

Steel fibre kuhloswe ukuba ngcono izici qualitative we ukhonkolo ngemva kokuba lithola amandla nomklamo walo. Kuyaphawuleka ukuthi ukusetshenziswa fiber silula, kodwa ubuchwepheshe ihlukile kuleyo ingasetshenziswa ngisho abantu abangenayo nelemuko elithe tjha endleleni emkhakheni wokwakha.

Lokhu kwaziswa efeza indima amandla, futhi inikeza nokwethenjelwa amapuleti. Metal fibre yakha isakhiwo ebumbeneko ikhambi ngesikhathi ukuxuba, okungase kwenziwe ngesandla noma ngomshini. Litholakala ngaphezulu futhi stalefibrobetona, okuyinto uhlobo ukhonkolo lapho umphini imisebenzi usebenze Imicu yotshani steel. Basuke yasakazwa kulo lonke ivolumu, futhi ukusetshenziswa okunjalo izakhiwo zikakhonkolo ivumela ukuze ususe kusukela engxenyeni ethile ukuqinisa, futhi ngezinye izikhathi kungaba ngakususi ngokuphelele khona ezivamile stem valve.

Ukwenza kahle ukusetshenziswa steel fibre ukhonkolo izakhiwo ibangelwa ukunciphisa umzamo ku umsebenzi yokugcizelela futhi isixazululo kanye nokwehla steel ukugeleza. Inqubo imisebenzi kungenzeka ukuhlanganisa futhi ekugcineni kwagcizelela mass ukhonkolo etholwe, esehlisa eyinkimbinkimbi by 27% futhi imali kwi zokwakha 1 m ³ eseqedile umkhiqizo.

Inkambu ukusetshenziswa kwento

Steel fibre ingasetshenziswa:

• floorings zezimboni;
• panel Kumisiwe;
• yinqwaba;
• izindonga engaphansi;
• screeds.

Phakathi kwezinye izinto, lo ezisetshenziselwa ukuvuselelwa izisekelo, izakhiwo prefabricated, emgwaqweni nokusekelwa panel.

Izinzuzo main imicu steel

Uma esikhundleni anezikhala phezu fibre, ukushuba screed kuyehla kakhulu, kuyilapho esithwele umthamo wayo bahlale. Ngakho isakhiwo stalefibrobetonnnye abe ukumelana imithwalo static kanye ashukumisayo. Umklamo kuthatha izinga ufa ukumelana, nemihuzuko ukumelana, vibration inyuka ukukhuthazela amandla.

Uma iqhathaniswa nezinhloko-bendabuko steel fibre ukugcizelela, kungase kuqashelwe ukuthi isikhathi esichithwa ukufakwa ama-valve, sinciphile. Lokhu kungenxa yokuthi i-fibre steel is sesingezwa mixer noma embonini, kanye nesikhathi ukuxuba zingaba khona cishe usuku imizuzu 5 kuya ku-15. Vibration ukumelana ngenxa yokuthi ukuthi imithwalo zabiwa ngokulinganayo futhi akusho nesandla ekubhujisweni ngokhonkolo. Kodwa uma ubeka nemigoqo yokugcizelela ngesikhathi ukuthelwa isisekelo, ngeke iphazamise kumiswa ukuqhekeka okuncane. Stalefibrobetona ine ukumelana kakhudlwana ukugqwala. Uma imiphumela emibi izoba ngaphansi ukuqinisa, umthamo yayo kuzokhulisa kakhulu ekuklanyweni ukuthi kuzokwenza lapho kubhujiswa lesi ungqimba zokuzivikela.

imphawu letibalulekile

Uma steel fibre sengezwe ukhonkolo lapho kudalwa izakhiwo ezihlukahlukene, lwakamuva bayoba izimfanelo ephakeme eguqa amandla futhi ukunwebeka, phakathi kwezinye izinto, lekumele azuzwe umkhawulo we compressibility namandla okusezingeni eliphezulu nomthelela. Ukusebenzisa izakhi idatha zingancishiswa ukuncipha futhi ukusonteka ungangena. Imikhiqizo etholakele thermo-, isithwathwa ukumelana nomlilo, futhi Ubuye ikhono eliphezulu ukuba simelane nemihuzuko.

izici lobuchwepheshe

Steel fibre for ukhonkolo, izithombe ezingafaneleki okusesihlokweni esithi liyingxenye wire, ubude baso ziyahlukahluka kusuka 0.5 kuya 1.2 mm. Ubude izakhi kuhluka 25 kuya ku-60 mm. Uma une sihlolisise fibre, kwazeke ukuthi injongo yawo ludinge ukuhlelwa okukhethekile, lwenza sikwazi ukubambelela siqinise ikhambi.

Izakhi zenziwa kusukela ongaphakeme carbon wire, elingelakwaJuda omunye ezintathu amakilasi amandla. It libhekene ngowokuqala 1.150 MPA, kuyilapho lesibili nelesithathu ibe namandla e 1335 kanye 1550 MPA, ngokulandelana. Ukusetshenziswa imicu steel kwezinye izimo kunezinzuzo phezu ukusetshenziswa valve. Steel fibre for ukhonkolo, ukusetshenziswa m3 ngamunye okuyinto mayelana 25-50 kg, yakha isakhiwo ngakuthathu olukwaziyo withstanding ukucindezeleka eqine futhi aqede microcracks ukudalulwa. Lesi sakamuva singabangela zimiswe bedle ukucindezeleka futhi umzamo umswakama. Ekugcineni, steel fibre ukhonkolo kungenziwa eziqhutshwa ngaphandle kwesidingo ukulungisa.

Zinkulu izinzuzo zokonga usebenzisa fibre

Steel fibre for ukhonkolo, ukugeleza eye eshiwo ngenhla aqede ukubambezeleka ukusebenza okubangwa yileli ukufakwa iziqobosho ezivamile. Ngakho-ke, ukubeka igridi phansi akudingekile uma ukukhiqizwa kwenziwa ezindaweni eziningi enezisekelo zikakhonkolo. Uma wengeza lezi zinto steel kungabandakanya inombolo sakugcina kwebasebenti kanye ukwakhiwa ukhonkolo yalo kuyomelwe izimfanelo ephakeme, okuyinto obonakaliswe yokuthi eqine futhi flexural amandla ukhula ngokuphindwe izikhathi ezingu-2, kanye esiphezulu eqine uhlobo kuyathuthuka by izikhathi ezingu-20. Etholwe usebenzisa isakhiwo fibre ngisho izifunda ukugadlwa ukuzamazama komhlaba enobungozi lingasetshenziswa.

amazinga isimo

Steel fibre for ukhonkolo, okuyinto ifana GOST 3282-74 limelela i material ihange okwenziwé wire engagqwali. Umngcele we-ebaluleke kakhulu ukuthi inquma imithetho yokukhiqiza - lena ukumelana yesikhashana, nezoqala kusukela uphawu 900 N / mm ^2. Lokhu kwaziswa isetshenziswa womshini liquid screed, lezisekelo yokugcizelela futhi izindawo zokuhamba yokutakula. Lokhu fibre isetshenziswa ihange imishini industrial, izinqaba, ibhuloho izakhiwo, zezindiza kanye imisele yamanzi.

Ngo ukuhweba futhi ingabhekana ephezulu carbon Imicu yotshani steel kusukela wire, okuyinto ngesikhathi womshini zethusi camera ingxube. Kulokhu kubukeka sengathi GOST 9389-75, namandla eqine we indaba iqala kusukela 1200 N / mm ^2.

Izimpawu Dramix Imicu yotshani

Uma unesithakazelo steel fibre ukhonkolo Dramix, kufanele bajwayelane nezici zayo. Yenziwe carbon ongaphakeme steel wire, esihlinzeka ukuqinisa ngakuthathu. Lokhu fibre emise ngakho ithobela kahle matrix ukhonkolo. Sebenzisa le nto kungaba flooring ebhizinisini, womshini tubing imigudu, ukukhiqizwa sishaye ukhonkolo kanye noma kunjalo uma kukhona isidingo ngcono izici ikhwalithi ukhonkolo.
