Mitundu ndi mawonekedwe achitsulo

I. Mbale yachitsulo ndi Mzere
Chitsulo mbaleamagawidwa mu mbale wandiweyani zitsulo, mbale woonda zitsulo ndi zitsulo lathyathyathya, specifications ndi chizindikiro "a" ndi m'lifupi x makulidwe x kutalika mu millimeters. Monga: 300x10x3000 kuti m'lifupi mwake 300mm, makulidwe a 10mm, kutalika kwa 3000mm zitsulo mbale.

Wandiweyani zitsulo mbale: makulidwe kuposa 4mm, m'lifupi 600 ~ 3000mm, kutalika 4 ~ 12m.
Woonda zitsulo mbale: makulidwe zosakwana 4mm, m'lifupi 500 ~ 1500mm, kutalika 0.5 ~ 4m.
Chitsulo chathyathyathya: makulidwe 4 ~ 60mm, m'lifupi 12 ~ 200mm, kutalika 3 ~ 9m.
Ma mbale ndi mizere yachitsulo amagawidwa motsatira njira yogudubuza:ozizira adagulung'undisa mbalendiotentha adagulung'undisa mbale; malinga ndi makulidwe: mbale zoonda zachitsulo (pansi pa 4mm), mbale zachitsulo (4-60mm), mbale zowonjezera (pamwamba pa 60mm)

2. Chitsulo choyaka moto
2.1Ndi - mtengo
Chitsulo cha I-beam monga momwe dzina lake likusonyezera, ndi mawonekedwe a I-woboola pakati, ma flanges apamwamba ndi apansi amatuluka.
Chitsulo cha I-mtengo chimagawidwa kukhala wamba, kuwala ndi mapiko m'lifupi mwa mitundu itatu, ndi chizindikiro "ntchito" ndi chiwerengero cha ananena. Ndi nambala iti yomwe imayimira kutalika kwa gawo la nambala ya centimita. 20 ndi 32 pamwamba pa mtengo wamba wa I, nambala yomweyi ndikugawidwa kukhala a, b ndi a, b, c mtundu, makulidwe ake a ukonde ndi m'lifupi mwake ndi 2mm motsatana. monga T36a kuti mtanda gawo kutalika 360 mm, ukonde makulidwe a kalasi wamba I-mtengo. I-beams ayenera kuyesa kugwiritsa ntchito thinnest ukonde makulidwe a mtundu a, amene ali chifukwa cha kulemera kwake, pamene mphindi ya gawo la inertia ndi yaikulu.
Mphindi ya inertia ndi radius ya gyration ya matabwa a I-m'mbali mwake ndi yaying'ono kwambiri kuposa yomwe ili pamtunda. Chifukwa chake, pali zoletsa zina pakugwiritsa ntchito, zomwe nthawi zambiri zimakhala zoyenera kwa mamembala anjira imodzi.
3.chitsulo njira
Channel zitsulo lagawidwa mitundu iwiri ya zitsulo wamba njira ndi opepuka njira zitsulo. Mtundu wachitsulo wachitsulo ndi chizindikiro """" ndi chiwerengero cha adanena." Chomwecho ndi mtengo wa I, chiwerengero cha masentimita chimaimiranso kutalika kwa gawoli. Monga [20 ndi Q [20], m'malo mwa gawo la kutalika kwa 200mm zitsulo zachitsulo ndi zitsulo zopepuka. Ndi - mtengo.

 

4. ngodya zitsulo
Ngongole zitsulo lagawidwa mitundu iwiri ya equilateral ngodya zitsulo ndi wosafanana ngodya zitsulo.
Equilateral ngodya: mbali zake ziwiri perpendicular m'litali wofanana, chitsanzo chake ndi chizindikiro "L" ndi nthambi m'lifupi x nthambi makulidwe mu millimeters, monga L100x10 m'lifupi nthambi 100mm, makulidwe a 10mm equilateral ngodya.
Osafanana ngodya: mbali zake ziwiri perpendicular perpendicular awiri si ofanana, chitsanzo ndi chizindikiro "" ndi yaitali nthambi m'lifupi x lalifupi nthambi m'lifupi x makulidwe a nthambi mu millimeters, monga L100x80x8 kwa kutalika kwa 100mm m'lifupi, lalifupi nthambi m'lifupi 80mm, makulidwe a 8mm osafanana ngodya.

 
5. H-mtengo(wokulungidwa ndi weld)
H-mtengo ndi wosiyana ndi I-mtengo.
(1) flange lalikulu, kotero pakhala pali flange lalikulu I-mtengo anati.
(2) Pakatikati mwa flange sichiyenera kukhala ndi malo otsetsereka, malo apamwamba ndi apansi amafanana.
(3) kuchokera ku mawonekedwe a kugawa zinthu, I-mtengo mtanda gawo la zinthu makamaka anaikira ukonde mozungulira, kwambiri mpaka mbali ya kutambasuka, zitsulo zochepa, ndi adagulung'undisa H-mtengo, kugawa zinthu kuganizira m'mphepete mwa gawo.
Chifukwa cha izi, mawonekedwe a H-beam cross-sections mwachiwonekere ndi apamwamba kuposa ntchito zachikhalidwe, njira, ngodya ndi kuphatikiza kwawo kwa magawo, kugwiritsa ntchito zotsatira zabwino zachuma.
Malinga ndi masiku ano dziko muyezo "hot adagulung'undisa H-mtengo ndi gawo T-mtengo" (GB/T11263-2005), H-mtengo lagawidwa m'magulu anayi, amene amatchulidwa motere: lonse flange H-mtengo - HW (W kwa Chotambala English prefix), specifications 100mmx100mm ~ 400mmx40; pakati flange H-mtengo - HM (M for Middle English prefix), specifications from 150mmX100mm~600mmX300mm: Narrow Cui-m'mphepete H-mtengo - HN (N for Narrow English prefix); mipanda yopyapyala ya H-beam - HT (T ya Thin English prefix). Kuzindikiritsa kwa H-mtengo kumagwiritsidwa ntchito: H ndi mtengo wa kutalika kwa h mtengo x m'lifupi mwa mtengo wa b x mtengo wa makulidwe a intaneti t mtengo x mtengo wa makulidwe a flange t2 mtengo wanenedwa. Monga H800x300x14x26, ndiye kuti, kutalika kwa gawo la 800mm, flange m'lifupi mwake 300mm, makulidwe a ukonde 14mm, makulidwe a flange a 26mm H-mtengo. Kapena anasonyeza poyamba ndi zizindikiro HWHM ndi HN anati H-mtengo gulu, kenako "m'litali (mm) x m'lifupi (mm)", monga HW300x300, ndiko kuti, gawo kutalika kwa 300mm, flange m'lifupi 300mm lonse flange H-mtengo.
6. T-mtengo
Sectional T-mtengo (Chithunzi) lagawidwa m'magulu atatu, kachidindo ndi motere: lonse flange mbali ya T-mtengo - TW (W kwa Wide English mutu); mu flange mbali ya T-mtengo - TM (M kwa Middle English mutu); yopapatiza flange mbali ya T-mtengo - TN (N kwa Narrow English mutu). Gawo T-mtengo ndi lolingana H-mtengo pakati pa ukonde wofanana anagawanika. Magawo a T-mtengo wamtengo wolembedwa ndi: T ndi kutalika h mtengo x m'lifupi b mtengo x makulidwe a intaneti t mtengo x makulidwe a flange t mtengo. Monga T248x199x9x14, ndiye kuti, kutalika kwa gawo 248mm, mapiko m'lifupi ndi 199mm, makulidwe a 9mm, makulidwe a flange a 14mm T-mtengo. Angagwiritsidwenso ntchito ndi H-mtengo kuimira ofanana, monga TN225x200 kutanthauza, gawo kutalika 225mm, flange m'lifupi 200mm yopapatiza flange gawo T-mtengo.

7.structural zitsulo chitoliro
Chitoliro chachitsulo monga gawo lofunikira la chitsulo ndi zitsulo, chifukwa cha kupanga kwake ndi mawonekedwe a chitoliro chomwe chimagwiritsidwa ntchito muzoyipa zosiyanasiyana ndipo chimagawidwa kukhalaChitoliro chachitsulo chosasinthika(zozungulira zoipa) ndiwelded zitsulo chitoliro(mbale, ndi zoipa) magulu awiri, onani Chithunzi.
Chitsulo dongosolo ambiri ntchito otentha adagulung'undisa zitsulo chitoliro ndi welded zitsulo chitoliro, welded zitsulo chitoliro adagulung'undisa ndi welded kuchokera Mzere zitsulo, malinga ndi kukula kwa m'mimba mwake chitoliro, ndipo anawagawa mu mitundu iwiri ya kuwotcherera msoko molunjika ndi kuwotcherera kozungulira.Chitoliro chachitsulo cha LSAWmfundo za m'mimba mwake akunja 32 ~ 152mm, khoma makulidwe a 20 ~ 5.5mm. Miyezo ya dziko la "LSAW chitsulo chitoliro" (GB/T13793-2008). Structural zitsulo chitoliro mopanda malire malinga ndi dziko muyezo "structural msokonezo chitoliro" (GB/T8162-2008), pali mitundu iwiri ya otentha adagulung'undisa ndi ozizira kukokedwa, chitoliro ozizira kukokedwa ndi malire ang'onoang'ono chitoliro m'mimba mwake, otentha adagulung'undisa opanda chitsulo chitoliro kunja awiri a 32 ~ 630mm, khoma makulidwe a 25mm ~ 75mm.
Zofotokozera zakunja kwa m'mimba mwake x makulidwe a khoma (mm), monga φ102x5. Welded zitsulo chitoliro akupindika ndi welded ndi Mzere zitsulo, mtengo ndi otsika. Chitsulo chitoliro mtanda gawo symmetry diso m'dera kugawa ndi wololera, mphindi ya inertia mbali zonse ndi utali wozungulira gyration ndi chimodzimodzi ndi zazikulu, kotero ntchito mphamvu, makamaka pamene axial kuthamanga ndi bwino, ndi mawonekedwe ake pamapindikira kumapangitsa kukhala wochepa kukana mphepo, mafunde, ayezi, koma mtengo ndi okwera mtengo kwambiri ndi dongosolo kugwirizana nthawi zambiri zovuta.
