Amakuru - Ibisobanuro, Ibikoresho n'Imikoreshereze ya ASTM H Beam | Umutanga Umushinga w'Umutako w'Ibyuma Binini

Nubwo ishoramari mu bikorwa remezo mpuzamahanga ririmo kwiyongera muri Amerika ya Ruguru, Amerika y'Epfo, no mu majyepfo y'uburasirazuba bwa Aziya,ASTM H BeamIracyari mu bice by'ibyuma bikunzwe cyane bikoreshwa mu bwubatsi bw'ubucuruzi, inganda, n'ibikorwa remezo. Ifite umutwaro mwinshi, ihamye kandi ijyanye n'ibipimo bya Amerika. Ikoreshwa cyane mu nyubako zitanga umusaruro mwiza ku isi.

ASTM-A572-Gr50-A992-Ubugari-Bwa-Ipe-270-Ipe-300-Heb-260-Hea-200-Ubwubatsi-Buri-Buri-Buri (1)

Ibisobanuro by'ingenzi bya ASTM

Imirasire ya ASTM H (izwi kandi nka imirasire y'urukiramende rugari) ikunze gukorwa hakurikijwe ibi bikurikira:

ASTM A36 Umurabyo wa H– Ibyuma bya karuboni byubatswe muri rusange ku nyubako no ku mishinga yoroheje y'inganda
ASTM A572 Umurabyo wa H– Icyuma cya HSLA gifite igipimo cyo gukomera hagati y’uburemere n’ubunini cyazamuwe
ASTM A992 Umurabyo wa H– Igipimo cyiza ku mirasire y'ubwubatsi bw'urukuta rugari ku isoko rya Amerika
ASTM A588 Umurabyo wa H– Icyuma kidakozwa n'inkongi ku biraro no hanze

Muri izi, ubwoko bukunze kugaragara cyane muri Amerika niUmuringa wa ASTM A992 w'urukiramende rugari, ifite imbaraga zingana cyane, ubushobozi bwo gusudira no gutwara ibintu mu buryo buringaniye.

Imiterere y'ibikoresho n'imikorere ya mekanike

Porogaramu z'ingenzi

Imiterere isanzwe ya mekanike (itandukana bitewe n'urwego):

Imbaraga z'umusaruro: 250–345 MPa (36–50 ksi no hejuru yayo)
Imbaraga zo Gukurura: 400–550 MPa
Ubusoderi bwiza cyane kandi bunoze
Ubudahangarwa bukomeye bwo kunama no gukanda

Igice cy'umurambararo gifite ishusho ya H gitanga:

1. Moduli y'igice kinini

2. Gukwirakwiza imizigo neza

3. Ikoreshwa ry'icyuma ryagabanutse ugereranije n'imiringa isanzwe ya I

4. Imikorere myiza cyane mu bihe by'imitingito n'imiyaga

Umwanzuro wa ASTM H Beam

ASTM H Beam cyangwa Wide Flange Beam ni ibicuruzwa bikomeye mu bwubatsi bw'ibyuma muri iki gihe. Nubwo umushinga waba ari uw'ububiko bw'inganda, ubw'ibyuma by'ubucuruzi, cyangwa ubwubatsi bw'ibiraro, imitako ya H y'imiterere ya ASTM itanga imbaraga, ukwizerwa no kubahiriza amategeko ku isi yose.

Ku bashoramari bohereza ibyuma mu mahanga n'abubatsi, bizaba ngombwa ko bahitamo umucuruzi w'ibyuma bya H wizewe ushobora kuzuza ibisabwa mu rwego rwo hejuru kandi byemejwe n'ibipimo mpuzamahanga kugira ngo bakomeze guhatana mu mwaka wa 2026 no mu yindi myaka itaha.
