H nur nima?
Strukturaviy po'lat 1890 yilda qurilgan Rand Mcnally Building birinchi po'latdan yasalgan binodan beri savdo binolarni qurishda keng qo'llanilgan.
O'shandan beri po'lat yirik qurilish loyihalari uchun ishlatilgan. Po'latning mavjudligi uni ishlatishni ancha osonlashtiradi.
Birinchidan, u beton bilan yaxshi bog'lanadi va ko'plab xususiyatlarga ega, bu qurilish loyihalari haqida gap ketganda uni betondan ham yaxshiroq qiladi.
Chelik hali ham qurilishda eng maqbul moddiy variantlardan biri hisoblanadi, chunki uni qurish uchun ozroq vaqt ketadi va engillik, yuqori quvvat va ishlab chiqarish qulayligining mukammal kombinatsiyasiga hissa qo'shadi.

H-Beam va I-Beam o'rtasidagi farq
H-Beam va I-Beam asoslari
H nurlari, nomidan ko'rinib turibdiki, haddelenmiş po'latdan yasalgan H shaklidagi konstruktiv element bo'lib, keng gardishli nur sifatida tanilgan.
Bu Qo'shma Shtatlarda eng ko'p ishlatiladigan tarkibiy qismlardan biridir. Bu tasavvurlar bo'ylab "H" ga o'xshaydi va nihoyatda kuchli va nurning kesimida katta sirtga ega.
Boshqa tomondan, men nurni H nur deb ham atashadi, lekin u kesmaning "I" siga o'xshaydi. Bu asosan haddelenmiş po'latdan yasalgan nur yoki I bosh harf shaklida kesimiga ega nur.
