Qhov sib txawv thiab zoo sib xws ntawm cov hlau tsis sib luag ceg thiab cov hlau sib luag ceg yog dab tsi?

Galvanized lub kaum sab xis hlaumuaj ob sab ntev sib npaug, tsim kom muaj lub qauv zoo sib xws. Ib qho kev qhia tshwj xeeb, xws li ∠50 × 50 × 5, qhia tias ob sab yog 50 hli dav thiab 5 hli tuab. Vim nws cov duab tsis tu ncua thiab kev faib tawm kev ntxhov siab sib xws, nws feem ntau siv rau hauv cov qauv uas xav tau kev thauj khoom sib npaug.

ceg tsis sib npauggalvanized kaum sab xis bar, raws li lub npe qhia, muaj ob sab ntawm qhov ntev sib txawv. Piv txwv li, ∠100 × 80 × 8 sawv cev rau sab ntev ntawm 100 hli, sab luv ntawm 80 hli, thiab phab ntsa tuab ntawm 8 hli. Qhov kev tsim qauv tsis sib xws no tso cai rau nws ua lub luag haujlwm tshwj xeeb txawm tias nyob rau hauv cov qauv tsis sib xws lossis nyob rau hauv cov kev txwv tshwj xeeb, ua rau muaj kev siv cov khoom siv zoo tshaj plaws.

1. Cov hlau kaum sab ntev sib npaug zos yog tib yam; piv txwv li, cov hlau kaum sab xis No. 4 feem ntau siv yog hais txog 40 × 40 × 4 hlau kaum sab xis. "40x40" qhia tias ob sab yog 40 hli; yog tias ob sab yog tib qhov ntev, nws yog hlau kaum sab xis sib npaug zos; thaum cov hlau kaum sab xis tsis sib npaug zos muaj cov sab ntev sib txawv, nrog ib sab ntev dua lwm sab;
2. Cov lus qhia txog cov hlau uas muaj ceg sib npaug zos txij li No. 2 txog No. 20; cov lus qhia txog cov hlau uas muaj ceg sib npaug zos txij li ∟50*32 txog ∟200*125;
3. Cov hlau sib npaug ntawm lub kaum sab xis yog siv dav hauv cov qauv tsim xws li cov choj, cov pej thuam kis, cov tshuab nqa thiab thauj khoom, nkoj, thiab cov txee rau khoom; cov hlau sib npaug ntawm lub kaum sab xis yog siv dav hauv ntau yam kev lag luam hauv nroog, pej xeem, pej xeem, thiab tub rog, xws li cov nqaj hlau hauv tsev lag luam, cov cub tawg hauv kev lag luam, cov pej thuam teb, thiab cov txee thawv. Vim tias nws siv tsawg dua li cov hlau ib ceg, nws tus nqi siab dua.

1. Cov khoom siv ntawm ceg sib npauglub kaum sab xis hlauthiab ceg tsis sib npauglub kaum sab xisyog tib yam: Q235B lub kaum sab xis hlau thiab Q345B lub kaum sab xis hlau;
2. Feem ntau cov qauv ntev yog: 6m lub kaum sab xis hlau, 9m lub kaum sab xis hlau, thiab 12m lub kaum sab xis hlau;
3. Txoj kev xam kuj zoo ib yam: Qhov hnyav ib 'meter' = 0.00785 * (Dav ntawm sab + Dav ntawm sab - Qhov tuab ntawm sab) * Qhov tuab ntawm sab.
