Mabhoti ndiwo akajairika zvigadzirwa zvehardware muhupenyu hwedu hwezuva nezuva uye anoita basa rakakosha muhupenyu hwedu.Nekudaro, vanhu vazhinji havanzwisise kutsanangurwa uye saizi yemabhaudhi.Nhasi, tichakupa sumo yesainzi kune iyo chaiyo inomiririra yeanchor bolts, tichitarisira kukubatsira.
1. Nheyo yebhaudhi yekusarudza zvinhu
Kazhinji kutaura, zvinhu zve anchor bolt zvinofanirwa kunge zviri Q235.Kana simba racho risina kukwana, iyo 16Mn anchor bolt inogona kusarudzwa kuburikidza nekuverenga.Kazhinji, Q235 anchor bhaudhi inoshandiswa, uye bhaudhi iri kusimba uye inodhonza-kunze inoshingirira.
Sezvineiwo, mabhaudhi anchor haachazotamba basa rakakura muchimiro chesimbi chakaiswa.Chikamu chete chesimba rekugera chiripo, nekuti basa guru nderokutsigira mushure mekuiswa, saka iyo yakatarwa inofanirwa kutaurwa pakusarudza mabhoti anchor.Muchokwadi, isu tinowanzo shandisa Q235B kana Q235A, uye kazhinji hatishandise Q345 hoko, nehurefu husingasviki 150mm.
Anchor mabhaudhi: anogona kukamurwa kuita midziyo anchor mabhaudhi uye magadzirirwo anchor mabhaudhi.Kusarudzwa kwemabhoti anchor kunofanirwa kutariswa kubva pakuona kwekunetsekana, ndiko kuti, shear, tensile uye torsional masimba anotakurwa neakagadziriswa mabhoti ekutsigira.Panguva imwecheteyo, semabhoti anchor, anofanirwa kunyanya kutakura simba rekugera.Naizvozvo, Q235 (uye kufunga nezve tembiricha yezvakatipoteredza kudzivirira "blue brittleness") inofanira kusarudzwa muzviitiko zvakawanda.Kana zvivakwa, zvimiro kana zvigadziriso zvakagadziriswa nemabhaudhi anchor emuno zvine kunetsa kuri pachena kana torsion pamabhaudhi anchor, yekutanga inofanirwa kuverengerwa uye kusarudzwa nedhayamita kana kusarudza zvakananga 16Mn ine yakanyanya kusimba simba, uye iyo yekupedzisira inofanirwa kugadziriswa nekuwedzera iyo. nhamba yemabhoti anchor.Mushure mezvose, zvinhu zvinodhura zvino.
Zviri nani kushandisa Q235A.Q235B inodhura kupfuura Q235A.Mabhaudhi eanchor haadi kusungwa, saka zvakanaka kushandisa Giredhi A.
2. Kugadzirisa tekinoroji yenheyo bolt zvinhu
Kugadziriswa kwechibatiso cheancho: tendeutsa shinda kutanga, wobva wakotamisa chirauro, woyambuka Q235 ine hurefu hwakafanana hwe150mm padyo nechiredzo.Mukuwedzera, zvinofanira kuonekwa kuti A3 inhamba yekare yechiratidzo, uye ikozvino inoenderana neQ235A.A3 simbi, iro ndiro zita rakapfuura.Kunyange zvazvo ichiri kushandiswa, inongogumira kumutauro unotaurwa.Zviri nani kusaishandisa mumagwaro akanyorwa.Isimbi yeClass A.Mugadziri wemhando iyi yesimbi anongovimbisa mashandiro emuchina asi kwete kuumbwa kwemakemikari kana abva mufekitori, Naizvozvo, izvo zvinosvibisa zvakaita seS uye P zvinogona kunge zvishoma, uye kabhoni yemukati inenge 0.2%, yakaenzana ne Nhamba 20 simbi, iyo yakaenzana neQ235 muhutano hutsva.A3 neA3F ndiwo mazita ekare eQ235-A, Q235-A.F A3 simbi uye Q235, Q345 ndiwo mamakisi kabhoni structural simbi.A3 ndiyo giredhi resimbi muyero yekare, asi yazvino chiyero (GB221-79) haina giredhi rakadaro.
Mune yazvino chiyero, A3 inosanganisirwa muQ235.Q235 inomiririra kuti simba regoho resimbi iyi 235MPa.Saizvozvo, 345 muQ345 inogona kupatsanurwa muzvikamu zvakawanda, kusanganisira: A - kuve nechokwadi chemichini zvinhu, B - kuve nechokwadi chemichini zvinhu uye inotonhora yekukotama zvinhu, C - kuve nechokwadi chekugadzirwa kwemakemikari ... Muchiyero chekare, zvinoreva A. , B, C haina kunyanya kusiyana neiyo muyero mutsva (Ndinofungidzira kuti iyi ndiyo nyaya), uye 1, 2, 3...... Inoshandiswa kuratidza simba.1 inomirira simba regoho re195MPa, 2 inomirira simba regoho re215MPa, uye 3 inomirira goho re235MPa.Saka A3 yakaenzana neQ235A mumhando nyowani.Mushure mezvose, A3 yakashandiswa kare, saka vanhu vakawanda vakajaira kuishandisa, sezvakangoita vamwe vakajaira kushandisa zvikamu zve "jin, liang".Q235 isimbi yekabhoni.Kuenzaniswa neyekare mwero GB700-79 mamakisi, A3 uye C3 Q345 yakaderera alloy structural simbi.Kuenzaniswa neyekare chiyero 1591-88 mamakisi, kune yakawandisa zvivakwa uye mashandisiro e12MnV, 16Mn 16MnRE, 18Nb uye 14MnNb Q345 - shaft uye weldment zvine yakanaka yakazara ma mechanical zvivakwa, yakaderera tembiricha zvivakwa, yakanaka plasticity uye weldability.Iwo anoshandiswa seane simba anotakura zvinhu zvinotakura zvimiro, mechanicha zvivakwa, uye akajairwa simbi zvimiro zvepakati uye zvakaderera midziyo yekumanikidza, matangi emafuta, mota, crane, michina yemigodhi, zvidyarwa zvemagetsi, mabhiriji, nezvimwewo, uye zvinogona kushandiswa mukupisa. kukunguruka kana normalizing mamiriro.Inogona kushandiswa kune akasiyana zvimiro munzvimbo dzinotonhora pazasi - 40 ℃.
