Steel internet kongiri: features, GOST

Steel faibha rinotarisirwa kuvandudza Qualitative zvechadenga kongiri shure Chinobudirira ayo patani simba. Zvinokosha kuziva kuti kushandisa faibha nyore chaizvo, asi unyanzvi yakasiyana pakuti rinogona kushandiswa kunyange vanhu vasina ruzivo zvikuru pasango kuvakwa.

Izvi zvinhu anozadzika basa simba, uye anopa kuvimbika kwamahwendefa. Metal faibha unoumba munhu unitary chivako chine mhinduro panguva nokusanganisa, izvo zvinogona kuitwa manually kana mechanically. It kunoitika zvakawanda uye stalefibrobetona, riri nekongiri rudzi iyo vharafu mabasa anoshanda simbi fibers. Vari richiparadzirwa munyika vhoriyamu, uye kushandisa kongiri hurongwa dzakadaro kunoita kuti kubvisa imwe nhengo chisimbiso, uye dzimwe nguva anogona siya zvachose kuvapo kwakajairika hunde vharafu.

Kunyatsoshanda pakushandisa kwakaita sesimbi internet kongiri zvakagadzirwa kunokwanisika Akaroromesawo nesimba pamusoro unowedzera basa uye mhinduro uye simbi chekubuda rutapudzo. Process akavhiyiwa zvinogoneka chokubatanidza uye pakupedzisira yanyatsosimba kongiri gobvu ndawana, izvo zvinoderedza kunzwisisa 27% uye mari pamusoro zvokuvakisa 1 mamita ³ vakapedza chigadzirwa.

Munda kushandiswa mashoko

Steel faibha inogona kushandiswa:

• maindasitiri floorings;
• Yakaturikwa pangoro;
• inoungana;
• bhesimendi masvingo;
• screeds.

Pakati pezvimwe zvinhu, mashoko akashandiswa pakuberekwa kutsva bwezvingoro, zvivako prefabricated, mumigwagwa uye rutsigiro ukomba.

The chikuru zvakanakira simbi fibers

Kana kutsiva munhu pajira riya pamusoro faibha, kuti screed ukobvu ipfupi zvikuru, apo kwayo kutakura vanokwanisa kuramba. Saka stalefibrobetonnnye maumbirwo vane refu kuramba kunofambira mberi uye vakagwinya zvinorema. Magadzirirwo anotora nokunaka mutswe nemishonga, abrasion nemishonga, vibration kunowanda kutsungirira uye simba.

Pakunoenzaniswa chinyakare simbi internet chisimbiso, zvinogona kucherechedzwa kuti nguva yakawandisa kugadzwa mavharuvhu, ipfupi. Izvi imhaka yokuti simbi faibha inowedzerwa kupinda chisanganiso kana mufekitari, uye kuvhenganisa nguva agare kubva 5 kusvika 15 maminitsi. Vibration kuramba nokuti kuti mitoro anoparadzirwa zvakaenzana uye asingauyi zvinokonzera kuparadzwa kongiri. Asi kana imi akaisa muedzo mbariro panguva kudira nheyo, havangavi kuvhiringidza paumbwe makatsemuka duku. Stalefibrobetona ane rakawedzera nemishonga kuti ngura. Kana akadaro Migumisiro zvichava pasi chisimbiso, vhoriyamu kwayo achawedzera yekudyidzana pamasikiro kuti achaita kuparadzwa runodzivirira.

Key zvinhu

Kana simbi faibha inowedzerwa kongiri pakusika zvivako siyana, ekupedzisira achava mukuru unhu vachikotama simba uye elongation, pakati pezvimwe zvinhu, kubudirira paunogumira yacho compressibility uye yakakwirira zvazvinoita simba. Kushandisa date zvinhu zvingaderedzwa shrinkage uye zvinokambaira deformation. Products vakawana thermo-, chando, uye moto nemishonga, uye anewo refu anokwanisa kudzivisa abrasion.

rwokugadzira unhu

Steel faibha nokuti kongiri, mifananidzo iyo dzinoturwa munyaya iri chidimbu kubva waya, kureba zvinogona dzinosiyana 0.5 kusvika 1,2 mm. Kureba okunze zvichisiyana 25 kusvika 60 mm. Kana uine tikanyatsoongorora faibha, izvozvo akacherechedza kuti ayo miromo vane chinokosha configuration, kunosimudzirawo wakabata pamwe mumushonga.

Zvinhu zviri kubva pasi kabhoni waya, raiva imwe matatu makirasi simba. It dzinoratidzwa wokutanga 1.150 MPa, apo rechipiri nerechitatu vane simba muna 1335 uye 1550 MPa, ukuwo. Kushandiswa simbi fibers mune zvimwe zviitiko ane zvakwakanakira pamusoro pokushandiswa vharuvhu. Steel faibha nokuti kongiri, kunwa yokudengenyeka m3 riri pamusoro 25-50 makirogiramu, anoumba rimwe-dimensional matatu Chimiro iyo inokwanisa withstanding tensile mupfungwa uye anobvisa microcracks kuburitsa. The yokupedzisira inogona kuumbwa pasi pokudzora mupfungwa uye nesimba unyoro. Pakupedzisira, simbi internet chaicho chinogona kushanda pasina kudikanwa kugadziriswa.

Zvoupfumi zvakanakira kushandisa faibha

Steel faibha nokuti kongiri, aibuda iyo yave ataurwa pamusoro hakubvisi kunonoka anokonzerwa kugadzwa kwakajairika fasteners. Naizvozvo, kuisa grid pasi hakusi zvakakodzera kana kugadzirwa rinoitwa pasi nzvimbo huru kongiri Slabs. Kana achiwedzera izvi simbi zvinhu dzingasanganisira usingashandi nhamba yevashandi uye chesamende kuvakwa kwayo uchava yepamusoro unhu, varehwa pakuti tensile uye flexural simba inowedzera nokuda 2 nguva, uye kufadza tensile kugozha iri nani nokuda ka20. Vakawana kushandisa internet mamiriro kunyange seismically nengozi nharaunda angashandiswa.

mamiriro mitemo

Steel faibha nokuti kongiri, rinotarira kufanana GOST 3282-74 inomirira Mbambo zvinhu izvo zvakaitwa Stainless waya. Chinonyanya kukosha parameter kuti anosarudza kugadzira mitemo - iri pfupi nemishonga, iyo inotanga kubva chiratidzo 900 N / mm ^2. Izvi zvinhu rinoshandiswa kuti kugadzirwa emura uye screed, muedzo nezvigadziko uye kupora pavements. faibha ichi chinoshandiswa anchor the maindasitiri zvokushandisa, masvingo, bhiriji zvivako, runways uye waterworks.

In wezvokutengeserana uye anogona kusangana mukuru-kabhoni simbi fibers kubva waya, izvo panguva gadzira yendarira zvemapuranga nezvakasanganiswa. Muchiitiko ichi zvinoita sokunge GOST 9389-75, uye simba tensile emashoko anotanga kubva 1200 N / mm ^2.

Zvinoitwa Dramix fibers

Kana uchifarira simbi internet kongiri Dramix, unofanira vanyatsonzwisisa mamiriro ayo. Zvinonzi kubva pasi kabhoni simbi waya, iyo inopa-dimensional matatu chisimbiso. faibha Izvi zvokuti nayo inoomerera zvakanaka chesamende chizvaro. Shandisa mashoko aya anogona kuva flooring mubhizimisi, anogadzira zvinhu Tubing tunnels, kongiri spraying kugadzirwa uye chero zvazvingava kana zvichidiwa kuvandudza zvechadenga kongiri.
