Momwe Mungasankhire H Beam pa Ntchito Yanu

Mu kusintha kwachangu kwa malo omanga ndi zomangamanga,Mzere wa H(kapenamtanda waukulu wa flangeKusankha ) kumachita gawo lofunika kwambiri pa chitetezo, kukhazikika komanso ndalama za polojekiti yonse. Kuyambira nyumba zazitali mpaka nyumba yosungiramo katundu yamafakitale, kuyambira mlatho mpaka nyumba zamalonda, kusankha kolakwika kwa kuwala kwa H kungayambitse vuto la kapangidwe ka nyumba, mtengo wokwera, kapena chiopsezo cha moyo.

Zinthu Zofunika Kwambiri Posankha Mzere Woyenera wa H

Maziko a kusankha amayamba ndi kudziwa katundu womwe mtanda uyenera kunyamula. Zina mwa izi ndi:

1. Katundu Wofa (Kulemera Kosatha kwa Nyumba Yokha)

2. Zinthu zambiri zamoyo (anthu, mipando, magalimoto, chipale chofewa, ndi zina zambiri)

3. Katundu wamphamvu (mphepo, mphamvu za zivomerezi)

Akatswiri a zomangamanga amagwiritsa ntchito mapulogalamu owunikira kapangidwe ka zinthu kapena ma code opanga (monga, AISC ku US, Eurocode ku Europe, kapena miyezo ya GB ku China) kuti awerengere nthawi yopindika, mphamvu zodula, ndi malire a kupotoka.

Kutalika kwa Chigawo ndi Mikhalidwe Yothandizira

Ma span ataliatali amafuna kuwala komwe kumakhala ndi nthawi yochepa kwambiri kuti achepetse kupatuka. Mwachitsanzo:

1. Magawo afupiafupi (mpaka 6-8m) m'malo ocheperako nthawi zambiri amachitidwa ndi magawo ang'onoang'ono ~ kutalika kwa 150-200 mm.

2. Magawo apakati (mamita 26-49) m'nyumba zosungiramo zinthu nthawi zambiri amafunikira mipiringidzo ya 10-14" H.

3. Magawo akuluakulu kapena ntchito zolemera (milatho, maholo akuluakulu amafakitale) amafunika magawo okwana 400 mm+ kapena magiredi okhuthala.

Kalasi ya Zinthu ndi Mphamvu

Mitundu yachitsulo yomwe imagwiritsidwa ntchito kwambiri ndi iyi:

1.Mzere wa H wa ASTM A36 / A572 / A992(Muyezo wa US, mphamvu yoyerekeza ya zokolola 250-345 MPa)

2.EN S235 / S275 / S355 H Beam(Zachikhalidwe cha ku Ulaya)

3.GB Q235 / Q345 H Beam (Chitchaina)

Ma grade amphamvu kwambiri (monga Q345B kapena S355) amalola zigawo zopepuka kuti zikhale ndi katundu womwewo, zomwe zimachepetsa kulemera konse kwa zinthu ndi mtengo wa maziko - izi zimakopa makamaka m'malo ozungulira zivomerezi kapena pomanga nyumba zazitali.

Kukula ndi Mafotokozedwe a Miyeso

Matabwa a H amasankhidwa ndi kutalika × m'lifupi × makulidwe a ukonde × makulidwe a flange (metric) kapena kuzama kwa dzina + kulemera pa phazi lililonse (mfumu, mwachitsanzo, W8 × 40).

Masayizi otchuka ndi awa:

1. Ntchito yopepuka: 100 × 100 mm mpaka 200 × 100 mm

2. Ntchito yapakati: 250×250 mm mpaka 300×300 mm

3. Wolemera kwambiri: 400×200 mm ndi kupitirira apo

Nthawi zonse onani matchati a kukula koyenera kuti mudziwe makhalidwe a magawo (nthawi ya kulephera, gawo la magawo, kulemera pa mita imodzi) kuti zigwirizane ndi zosowa za polojekiti.

Zoganizira Zachilengedwe ndi Ntchito Zapadera

Kukana dzimbiri: Gwiritsani ntchito chitsulo cholimba, chopakidwa utoto, kapena chotentha (monga Corten) panja kapena pamalo onyowa komanso onyowa.

Kutha kulumikiza ndi kupangika: Onetsetsani kuti mulingo wake ukugwirizana ndi njira zolumikizira zomwe zimagwiritsidwa ntchito pamalopo.

Mtengo ndi kupezeka: Ganizirani momwe zinthu zilili poyerekeza ndi unyolo wogulira zinthu zakomweko—kusankha zinthu mopitirira muyeso kungapangitse kuti mtengo uwonjezereke ndi 20–50%.

Funsani Akatswiri

Kulemba ma code koyambirira kungagwiritse ntchito makina owerengera pa intaneti kapena matebulo a span, koma kusankha komaliza kuyenera kutsimikiziridwa ndi mainjiniya wovomerezeka. Kukula kokhazikika kudzakhala kogwirizana ndi ma code komanso koyenera kapangidwe kake - sikudalira kuwerengera kokha.

Pezani Mtengo Waulere kapena Funsani Mafunso Okhudzana ndi Zamalonda!
