Ub 914*419*388 UC 356*406*393 Hea Heb Hem 150 Imishayo Eshiselwe Eshiselwe Okushisayo H enamanani Angcono Kakhulu Umkhiqizi waseChina

Imishayo ye-HEA, HEB, ne-HEM inohlu olubanzi lwezinhlelo zokusebenza ezimbonini zobunjiniyela bezakhiwo. Okunye ukusetshenziswa okuvamile kuhlanganisa:

1. I-HEA beam (i-H-beam engasindi): Ifanele izinhlelo zokusebenza ezinomthwalo ophansi nezilula.

Izinzuzo eziyinhloko isisindo esilula, ukusetshenziswa okuphezulu kwezinto ezibonakalayo, nokufaka kalula. Izakhiwo zayo zemishini zihlangabezana nezidingo zokuthwala isisekelo, ziqeda isidingo sokuthwala imithwalo eyeqisayo. Izicelo zayo eziyinhloko yilezi:

Izakhiwo zomphakathi: imishayo yesibili, izikebhe zezindonga ezihlukanisayo, namafreyimu e-balcony ezakhiweni zokuhlala ezinezitezi/amafulethi;

Izinsiza zezimboni ezincane: izinhlaka ezisizayo zokweseka amafekthri angasindi (njengeplatifomu yemishini imishayo yesibili kanye namafreyimu ezindlela zokuhamba zokulungisa), namakholomu/imishayo yokubeka impahla;

Izicelo ezingathwali imithwalo noma ezithwele umthwalo ophansi: izikebhe zosilingi ezindaweni zentengiso (inxanxathela yezitolo, amahholo emibukiso), namafreyimu eshede angasindi esikhashana.

2. I-HEB Beam (I-H-Beam Emaphakathi): Ifanele izimo ezijwayelekile zokulayisha okuphakathi

Izinzuzo eziyinhloko zemishayo ye-HEB yizici zemishini ezilinganiselayo (ukugoba okumaphakathi nokumelana nokugunda), ukuguquguquka okunamandla, nokusebenza kahle kwezindleko okuphezulu. Zilala phakathi komklamo ongasindi wemishayo ye-HEA kanye nomklamo osindayo wemishayo ye-HEM. Ziwuhlobo olusetshenziswa kakhulu ekwakhiweni nakwengqalasizinda, ngezicelo eziyinhloko ku:

Izakhiwo zezimboni nezohwebo: Imishayo/amakholomu amakhulu amafekthri anosayizi omaphakathi, amafreyimu athwala imithwalo ezakhiwo zamahhovisi ezinezitezi, kanye nemishayo emikhulu ethwala imithwalo yezitolo ezinkulu nezindawo zokugcina impahla;

Ingqalasizinda emincane nephakathi nendawo: Imishayo emikhulu yamabhuloho emigwaqo yasemakhaya, izakhiwo ezithwala imithwalo ezindaweni ezidlula abahamba ngezinyawo emadolobheni, kanye nezisekelo zezindawo ezincane zokonga amanzi (njengemisele yamanzi);

Izinto zokusebenza nezakhiwo: Amafreyimu ayisisekelo emishini yosayizi omaphakathi (njengabasekeli bamathuluzi omshini), ozimele abakhulu bama-canopies ensimbi, namakholomu athwalayo ezindaweni zokupaka.

3. I-HEM beam (I-Heavy Duty H-Beam): Ifanele imithwalo ephezulu nezimo zokusebenza ezidlulele

Izinzuzo eziyinhloko zemishayo ye-HEM ama-web/ama-flange aminyene, izikhathi ezinkulu eziphambanayo ze-inertia, namandla aphezulu kakhulu okuthwala umthwalo. Bangakwazi ukumelana nezikhathi ezinkulu zokugoba, amandla aphezulu e-axial, nemithwalo eyinkimbinkimbi (njengomthelela nokudlidliza). Asetshenziswa ngokuyinhloko ku:

Izakhiwo zezimboni ezisindayo: Imishayo/amakholomu amakhulu ezimbonini zemishini esindayo (njengezindawo zemikhumbi nezitshalo zensimbi), amafreyimu asekelayo eziko lokwenza insimbi, nezisekelo zemishini esindayo (amakhreni nezigayo eziginqikayo);

Ingqalasizinda emikhulu: Imishayo emikhulu yomgwaqo onguthelawayeka/amabhuloho kaloliwe, ama-bearings amabhuloho awela umfula, kanye nemishayo yokuxhuma ikholomu yemigwaqo emikhulu yasemadolobheni ephakeme;

Izinhlelo zokusebenza ezikhethekile ezinengcindezi ephezulu: Ingxenye ethwala imithwalo engaphansi yemibhoshongo yokudlulisa, isekela imishayo yamasongo amathangi amakhulu okugcina (amathangi kawoyela ongahluziwe namathangi amakhemikhali), kanye nezisekelo zamathrekhi okuthutha athwala kanzima ezimayini ezingaphansi komhlaba.
