Chiyero chitsva chesimbi rebar chasvika uye chichaitwa zviri pamutemo mukupera kwaGunyana

Iyo nyowani vhezheni yenyika chiyero chesimbi rebar GB 1499.2-2024 "simbi yekusimbisa kongiri chikamu 2: inopisa yakakungurutswa ribbed simbi mabara" ichaitwa zviri pamutemo munaGunyana 25, 2024.

Munguva pfupi, kushandiswa kweiyo chiyero chitsva kune marginal kukanganisa pamutengo werebarkugadzirwa uye kutengeserana, asi nekufamba kwenguva inoratidza iyo yakazara inotungamira ideology yepolicy inopera kuvandudza kunaka kwezvigadzirwa zvemumba uye kusimudzira mabhizinesi esimbi kusvika pakati nepamusoro pekupedzisira kwemaindasitiri ketani.
I. Kuchinja kukuru muchiyero chitsva: kuvandudzwa kwemhando uye maitiro ekuvandudza
Kuitwa kweiyo GB 1499.2-2024 yakajairwa kwakaunza shanduko dzakakosha dzakati wandei, dzakagadzirirwa kuvandudza mhando yezvigadzirwa zve rebar uye kuunza China rebar zviyero zvinoenderana nepasi rose. Izvi zvinotevera shanduko ina dzakakosha:

1. Chiyero chitsva chinosimbisa zvakanyanya uremu kushivirira miganhu ye rebar. Kunyanya, iyo inotenderwa kutsauka kwe6-12 mm dhayamita rebar ndeye ± 5.5%, 14-20 mm ndeye +4.5%, uye 22-50 mm ndeye +3.5%. Shanduko iyi inozokanganisa kugadzirwa kweiyo rebar, ichida kuti vagadziri vagadzirise mwero wemaitiro ekugadzira uye kugona kwemhando yekudzora.
2. Kune yakakwirira-simba rebar mamakisi akadaiHRB500E, HRBF600Euye HRB600, chiyero chitsva chinoraira kushandiswa kwekunatsa ladle. Ichi chinodiwa chichavandudza zvakanyanya kunaka uye kugadzikana kwekuita kweiyi yakakwirira-simbasimbi mbariro, uye kuwedzera kukurudzira indasitiri kune kutungamira kwepamusoro-simba rekusimudzira simbi.
3. Kune chaiwo mamiriro ekushandisa, mwero mutsva unosuma kuneta kuita zvinodiwa. Shanduko iyi ichavandudza hupenyu hwesevhisi uye kuchengetedzeka kwerebar pasi pemitoro ine simba, kunyanya kumabhiriji, zvivakwa zvepamusoro-soro uye mamwe mapurojekiti ane zvinodiwa zvakanyanya zvekuneta kuita.
4. Iyo yakajairwa inogadziridza nzira dzesampling uye maitiro ekuyedza, kusanganisira kuwedzera reverse bending bvunzo ye "E" giredhi rebar. Shanduko idzi dzichavandudza huchokwadi uye kuvimbika kwekuyedzwa kwemhando, asi zvinogonawo kuwedzera mutengo wekuyedza kune vanogadzira.
Chechipiri, kukanganisa pamitengo yekugadzira
Kuitwa kweiyo chiyero chitsva kuchave kwakanakira mukuru wemabhizinesi ekugadzira tambo kusimudzira mhando yechigadzirwa, kuwedzera kukwikwidza kwemusika, asi zvakare kuunza mari yekugadzirwa kwemahombekombe: maererano netsvagiridzo, mukuru wemabhizinesi ekugadzira simbi anoenderana neiyo chiyero chitsva. mutengo wekugadzira chigadzirwa uchawedzera ne20 yuan / tani.
Chechitatu, kukanganisa kwemusika

Iyo chiyero chitsva ichasimudzira kusimudzira uye kushandiswa kwepamusoro simba zvigadzirwa zvesimbi. Semuyenzaniso, 650 MPa ultra-high-simba seismic simbi simbi mbariro anogona kugamuchira zvakawanda kutarisirwa. Shanduko iyi inotungamira kune shanduko mukusanganiswa kwechigadzirwa uye kudiwa kwemusika, izvo zvinogona kufarira iwo magiyo esimbi anogona kugadzira zvinhu zvepamberi.
Sezvo zviyero zvinosimudzwa, kudiwa kwemusika kwepamusoro-mhando rebar kuchawedzera. Zvishandiso zvinosangana nemiyero mitsva zvinogona kuraira mutengo wekutanga, izvo zvinokurudzira makambani kuti avandudze mhando yechigadzirwa.
