Square chitoliro ndi dzina lalikulu chitoliro ndi amakona anayi chitoliro, ndiye chitsulo chitoliro ndi wofanana ndi wosiyana mbali utali. Amapangidwa ndi chitsulo chopindika pambuyo pochiza. Nthawi zambiri, chitsulo chamzere chimatsegulidwa, chowongoleredwa, chophwanyidwa ndi chowotcherera kuti chipange chitoliro chozungulira, kenaka amakulungidwa mu chitoliro chozungulira kuchokera ku chitoliro chozungulira, ndikudula mu utali wofunikira.

1. Kupatuka kololeka kwa makulidwe a khoma la chitoliro chamzere sikuyenera kupitilira kuphatikizira kapena kuchotsera 10% ya makulidwe a khoma pomwe makulidwe a khoma siwopitilira 10mm, kuphatikiza kapena kuchotsera 8% ya makulidwe a khoma pamene makulidwe a khoma ndi ochulukirapo. kuposa 10mm, kupatula makulidwe a khoma la ngodya ndi madera otsekemera.

2. The mwachizolowezi yobereka chitoliro lalikulu amakona anayi chitoliro ndi 4000mm-12000mm, makamaka 6000mm ndi 12000mm. Chubu cha rectangular chimaloledwa kupereka zinthu zazifupi komanso zosakhazikika zosachepera 2000mm, komanso zitha kuperekedwanso ngati mawonekedwe a chubu, koma Demander azidula mawonekedwe a chubu akamagwiritsa ntchito. Kulemera kwa geji lalifupi ndi zinthu zosakhazikika siziyenera kupitirira 5% ya voliyumu yonse yobweretsera. Kwa machubu a mphindi yayikulu okhala ndi zolemetsa zochulukirapo kuposa 20kg / m, sizingadutse 10% ya voliyumu yonse yobereka.

3. Digiri yopindika ya chitoliro cha makona anayi sikhala wamkulu kuposa 2mm pa mita, ndipo digirii yopindika sikhala yayikulu kuposa 0.2% yautali wonse.

Malinga ndi kamangidwe kameneka, machubu apakati amagawidwa kukhala machubu otentha opindika opanda msokonezo, machubu ozizira osasunthika osasunthika, machubu akunja opanda msoko ndi machubu akulu akulu.

The welded lalikulu chitoliro chagawidwa mu

1. Malinga ndi ndondomeko - arc kuwotcherera lalikulu chubu, kukana kuwotcherera lalikulu chubu (mkulu pafupipafupi ndi otsika pafupipafupi), mpweya kuwotcherera lalikulu chubu ndi ng'anjo kuwotcherera lalikulu chubu

2. Malinga ndi weld - molunjika welded lalikulu chitoliro ndi ozungulira welded lalikulu chitoliro.

Gulu lazinthu

Machubu a square amagawidwa kukhala machubu wamba a carbon steel square ndi low alloy square chubu malinga ndi zinthu.

1. Wamba mpweya zitsulo anawagawa Q195, Q215, Q235, SS400, 20 # zitsulo, 45 # zitsulo, etc.

2. Chitsulo chochepa cha alloy chimagawidwa mu Q345, 16Mn, Q390, St52-3, etc.

Zopanga muyeso classification

Square chubu lagawidwa dziko muyezo lalikulu chubu, Japanese muyezo lalikulu chubu, British muyezo lalikulu chubu, American muyezo lalikulu chubu, European muyezo lalikulu chubu ndi sanali muyezo lalikulu chubu malinga ndi mfundo kupanga.

Gawo la mawonekedwe

Mapaipi a square amagawidwa molingana ndi mawonekedwe a gawo:

1. Gawo losavuta lalikulu chubu: chubu lalikulu, chubu lamakona anayi.

2. Square chubu ndi gawo zovuta: duwa zooneka lalikulu chubu, lotseguka lalikulu chubu, malata lalikulu chubu ndi wapadera woboola pakati chubu lalikulu.

Gulu lamankhwala apamwamba

Mapaipi apakati amagawidwa m'mapaipi otentha, mipope yamagetsi yama electro galvanized square, mapaipi apakati opaka mafuta ndi mipope yamapaipi osakaniza molingana ndi chithandizo chapamwamba.

Gwiritsani ntchito magulu

Machubu a square amagawidwa ndikugwiritsa ntchito: machubu apakati okongoletsa, machubu akulu azida zamakina, machubu akulu akulu amakampani opanga makina, machubu akulu akulu amakampani opanga mankhwala, machubu akulu akulu azitsulo, machubu apamtunda opangira zombo, machubu apamtunda agalimoto, machubu akulu zitsulo zitsulo ndi mizati, ndi masikweya machubu zolinga zapadera.

Gulu makulidwe a khoma

Machubu amakona anayi amagawidwa molingana ndi makulidwe a khoma: machubu owonjezera okhala ndi mipanda amakona anayi, machubu amipanda amakona anayi ndi machubu opyapyala okhala ndi mipanda yamakona anayi. Fakitale yathu ili ndi ukadaulo wopanga pamsika, ndipo ndi waluso kwambiri. Takulandilani anzanu apadziko lonse lapansi kuti mukambirane. Tidzayesetsa kukwaniritsa zosowa zanu zosiyanasiyana.
