Indlela Yokukhetha i-H Beam Yephrojekthi Yakho

Esimweni esishintsha ngokushesha sobunjiniyela bezakhiwo nokwakha,Umsebe ongu-H(nomaumqadi we-flange obanziUkukhetha kudlala indima ebaluleke kakhulu ekuphepheni, ekuzinzeni kanye nasekunothweni kwephrojekthi yonke. Kusukela esakhiweni esinde kuya endaweni yokugcina impahla yezimboni, kusukela ebhulohweni kuya esakhiweni sezentengiselwano, ukukhetha okungalungile kwe-H beam kungabangela inkinga yesakhiwo, izindleko zokudlula ukusebenza, noma ingozi yokuphila.

Izici Ezibalulekile Ekukhetheni I-H Beam Efanele

Isisekelo sokukhetha siqala ngokwazi imithwalo okumele ithwalwe yi-beam. Phakathi kwale mithwalo kukhona:

1. Imithwalo Efile (Isisindo Esihlala Njalo Sesakhiwo Ngokwaso)

2. Imithwalo ephilayo (abantu, ifenisha, izimoto, iqhwa, nokuningi)

3. Imithwalo enamandla (umoya, amandla okuzamazama komhlaba)

Ochwepheshe bobunjiniyela bezakhiwo basebenzisa isofthiwe yokuhlaziya isakhiwo noma amakhodi okuklama (isibonelo, i-AISC e-US, i-Eurocode eYurophu, noma amazinga e-GB eShayina) ukuze babale izikhathi zokugoba, amandla okusika, kanye nemikhawulo yokuphambuka.

Ubude be-Span kanye Nezimo Zokusekela

Iziphambano ezinde zidinga imisebe enesikhathi esiningi sokungaguquguquki ukuze kuncishiswe ukuphambuka. Isibonelo:

1. Izikhawu ezimfushane (kufika ku-6-8m) ekuthengisweni okulula zivame ukwenziwa ngezingxenye ezincane ~ ukuphakama okungu-150-200 mm.

2. Izinsika eziphakathi nendawo (26-49 feet) ezindaweni zokugcina impahla ngokuvamile zidinga imisebe engu-10-14" H.

3. Izitebhisi ezinkulu noma izinjongo ezinzima (amabhuloho, amahholo amakhulu ezimboni) zidinga izingxenye ezingu-400 mm+ noma amamaki amakhulu.

Ibanga Lezinto Ezibalulekile Namandla

Izinhlobo zensimbi ezisetshenziswa njalo yilezi:

1.I-ASTM A36 / A572 / A992 H Beam(Izinga elijwayelekile lase-US, amandla okukhiqiza alinganiselwa ku-250-345 MPa)

2.I-EN S235 / S275 / S355 H Beam(Isimiso saseYurophu)

3.GB Q235 / Q345 H Beam (isilinganiso sesiShayina)

Amazinga anamandla aphezulu (isb., Q345B noma S355) avumela izingxenye ezilula zomthwalo ofanayo, okunciphisa isisindo sezinto ezisetshenziswayo kanye nezindleko zesisekelo - lokhu kukhanga kakhulu ezindaweni zokuzamazama komhlaba noma ezakhiweni eziphakeme.

Imininingwane Yosayizi Nobukhulu

Imishayo ye-H ichazwa ngokuphakama × ububanzi × ubukhulu bewebhu × ubukhulu be-flange (i-metric) noma ukujula okujwayelekile + isisindo ngonyawo (umbuso, isib., i-W8×40).

Osayizi abadumile bahlanganisa:

1. Umsebenzi olula: 100 × 100 mm kuya ku-200 × 100 mm

2. Umsebenzi ophakathi nendawo: 250×250 mm kuya ku-300×300 mm

3.Umsebenzi onzima: 400×200 mm nangaphezulu

Njalo bheka amashadi osayizi ajwayelekile ukuze uthole izakhiwo zesigaba (isikhathi sokungahlali kahle, i-section modulus, isisindo ngemitha) ukuze kuhambisane nezidingo zephrojekthi.

Izinto Ezicatshangelwayo Ngezemvelo kanye Nephrojekthi

Ukumelana nokugqwala: Sebenzisa insimbi eqinisiwe, ependiwe, noma esesimweni sezulu (isb., iCorten) ezindaweni ezingaphandle noma ezinomswakama.

Ukushibilika kanye nokwakheka: Hlola ukuthi izinga liyahambisana nezinqubo zokushibilika ezisetshenziswa endaweni.

Izindleko nokutholakala: Cabanga ngokusebenza uma kuqhathaniswa neziteshi zokuphakelwa zendawo—ukunikeza imininingwane eyengeziwe kungakhuphula izindleko ngo-20–50%.

Xhumana Nochwepheshe

Ukubhala ikhodi kokuqala kungasebenzisa ama-calculator aku-inthanethi noma amathebula e-span, kodwa ukukhetha kokugcina kumele kuqinisekiswe unjiniyela wesakhiwo onelayisensi. Osayizi abajwayelekile bazohambisana nekhodi futhi bahambisane nesakhiwo - abasoze bancika ekubalweni okusemthethweni kuphela.
