Square yeeb nkab yog qhov nrov tshaj plaws, xav tau thiab dav hom dov hlau. Qhov tseem ceeb ntawm kev xaiv cov ntaub ntawv no tsuas yog lawv tus nqi tsim nyog.
Ib lub square hlau yeeb nkab muaj ib ntu nrog qhov sib npaug ntawm qhov siab thiab dav, thiab nws lub hom phiaj tseem ceeb yog kev tsim cov khoom siv ntxiv ntawm cov ncej thiab cov qauv kev txhawb nqa. Cov khoom siv yog siv hauv kev tsim kho kev lag luam thiab hauv kev tsim kho tshuab.
Square steel yeeb nkab yog dav siv los ua lub ntsiab load-bearing ntsiab ntawm lub hauv paus, formwork thiab hlau lug. Nws cov duab tshwj xeeb tso cai rau kev txhim kho sai thiab yooj yim, ua kom muaj kev ruaj ntseg ntawm cov tsev. Tsis tas li ntawd, cov khoom tau pom daim ntawv thov hauv kev tsim cov laj kab, rooj vag, thaum tsim cov laj kab zoo nkauj.
Cov yam ntxwv tseem ceeb ntawm cov kav dej square yog tswj hwm los ntawm lub xeev cov qauv uas txiav txim siab ntau yam ntawm cov ntaub ntawv profile. Yog li, cov khoom yog tsim los ntawm kub-kuav los tiag thiabtxias-draw txoj kev, nrog rau siv hluav taws xob vuam.
Nyob ntawm kev tsim tshuab, lub raj square tuaj yeem ua haujlwm txias thiab kub ua haujlwm. Cov hom no yog cov khoom siv seamless. Cov yeeb nkab siv vuam thev naus laus zis yog tsim los ntawm cov ntawv hlau.
Qhov ntev ntawm cov khoom sib txawv tuaj yeem sib txawv hauv cov phab ntsa tuab ntawm 1 txog 14 hli, thaum qhov profile dav tuaj yeem yog los ntawm 1 txog 18 centimeters. Cov yeeb nkab square yog tsim nyob rau hauv ntev los ntawm ib thiab ib nrab mus rau 12.5 meters. Tus nqi ntawm cov khoom yog nyob ntawm ob qho tib si ntawm kev tsim khoom thiab ntawm qhov loj. Yog tias tsim nyog, cov kav dej tuaj yeem ua rau xaj nrog qhov ntev dua li tus qauv.
Rau cov khoom siv, ob qho tib si carbon steel thiab alloy steel yog siv, nrog rau kev sib ntxiv ntawm ntau yam tshuaj. Qhov no tso cai rau koj kom tau txais cov khoom lag luam zoo thiab ua haujlwm zoo.
Square yeeb nkab tau pom dav siv hauv kev tsim kho niaj hnub vim nws cov khoom. Cov khoom muaj plaub lub stiffeners, me ntsis txo qis hauv qhov tawv nqaij ntawm qhov khoov thiab qhov hnyav qis hauv kev sib piv nrog rau lwm hom dov hlau. Qhov no tso cai rau cov khoom siv los ua cov txheej txheem.
Vim cov duab plaub ntawm cov khoom, cov txheej txheem ntawm kev tso cov kav dej rau ntawm qhov chaw tiaj tus yog yooj yim. Vuam yog siv los fasten cov ntaub ntawv, uas ua rau nws muaj peev xwm tsim cov qauv uas muaj peev xwm tsis kam mus rau lojloads.
Cov hlau zoo siv hauv kev tsim cov kav dej muab cov khoom lag luam nrog cov kav ntev, hnav tsis kam thiab corrosion kuj. Vim nws cov yam ntxwv geometric, square raj yog siv rau kev tsim cov chaw ua si, tes tuav, tsev cog khoom, qhov rais grilles, laj kab, qhov chaw siab tshaj, cov qauv tshaj tawm, chimneys, qhov cua racks thiab rooj tog zaum. Cov khoom siv kuj tau pom daim ntawv thov hauv kev lag luam tsheb.
