Muhimman Abubuwan Da Ke Taimakawa Wajen Zaɓar Hasken H Mai Dacewa

Tushen zaɓi yana farawa ne da sanin nauyin da dole ne katakon ya ɗauka. Daga cikin waɗannan akwai:

1. Matattu Nauyi (Nauyin Ginin Da Kansa Na Dindindin)

2. Yawan rayuwa (mutane, kayan daki, motoci, dusar ƙanƙara, da sauransu)

3. Nauyin da ke aiki (iska, ƙarfin girgizar ƙasa)

Ƙwararrun injiniyan gine-gine suna amfani da software na nazarin tsari ko lambobin ƙira (misali, AISC a Amurka, Eurocode a Turai, ko ƙa'idodin GB a China) don ƙididdige lokutan lanƙwasawa, ƙarfin yankewa, da iyakokin karkatarwa.

Tsawon Lokaci da Yanayin Tallafi

Dogayen tsayi suna buƙatar haske mai ƙarfi tare da ƙarin lokacin inertia don rage karkacewa. Misali:

1. Gajerun layuka (har zuwa mita 6-8) a cikin tallan haske yawanci ana yin su da ƙananan sassa ~ tsayin mm 150-200.

2. Matsakaicin tsawon (ƙafa 26-49) a cikin rumbunan ajiya gabaɗaya suna buƙatar hasken H mai tsawon inci 10-14.

3. Manyan wurare ko wuraren aiki masu nauyi (gadaje, manyan dakunan masana'antu) suna buƙatar sassa 400 mm+ ko maki mai kauri.

Matsayin Kayan Aiki da Ƙarfi

Nau'ikan ƙarfe da ake yawan amfani da su sune:

1.ASTM A36 / A572 / A992 H Beam(Matsakaicin Amurka, kimanin ƙarfin yawan amfanin ƙasa 250-345 MPa)

2.EN S235 / S275 / S355 H Beam(Dokar Turai)

3.GB Q235 / Q345 H Beam (al'adar Sinanci)

Ma'aunin ƙarfi mafi girma (misali, Q345B ko S355) yana ba da damar sassa masu sauƙi don nauyin iri ɗaya, wanda ke rage jimlar nauyin kayan aiki da farashin harsashi - wannan yana da kyau musamman a yankunan girgizar ƙasa ko don gine-gine masu tsayi.

Girman da Bayani dalla-dalla

Ana sanya hatimin H ta hanyar tsayi × faɗi × kauri na yanar gizo × kauri na flange (metric) ko zurfin da ba a san shi ba + nauyi a kowace ƙafa (imperial, misali, W8×40).

Girman da aka fi sani sun haɗa da:

1. Mai sauƙin aiki: 100 × 100 mm zuwa 200 × 100 mm

2.Matsakaicin aiki: 250×250 mm zuwa 300×300 mm

3. Nauyin nauyi: 400×200 mm da sama

Koyaushe duba jadawalin girman da aka saba amfani da shi don halayen sashe (lokacin inertia, modules na sashe, nauyi a kowace mita) don dacewa da buƙatun aikin.

Abubuwan da Za a Yi La'akari da su Kan Muhalli da Aiki

Juriyar Tsatsa: Yi amfani da ƙarfe mai galvanized, fenti, ko na yanayi (misali, Corten) a waje ko kuma a wurare masu danshi.
