M'zaka zaposachedwapa, monga ndalama dziko mu zomangamanga padziko lalikulu tauni ndi zomangamanga ntchito kwambiri ntchito zitsulo dongosolo, ndi lalikulu-kakulidwe wandiweyani-mipanda.mapaipi amakona anayi chifukwa cha maonekedwe okongola, mphamvu yololera, yosavuta processing nodesetc., motero m'mabwalo a ndege, mabwalo a masewera ndi msonkhano wachigawo wa truss structural system, ndi dongosolo lothandizira khoma lotchinga monga zigawo zazitsulo zimagwiritsidwa ntchito ponseponse.

Komabe, muzogwiritsira ntchito, chitoliro chachitsulo cha square ndi rectangular chinakumananso ndi mavuto ofulumira.Choyamba, zoweta zoweta zitsulo zooneka mu msika zambiri wamba mwatsatanetsatane m'mimba mwake, woonda-mipanda ozizira mawonekedwe zitsulo, zinthu zambiri Q235, pamene 300mm * 300mm * 12mm kapena kuposa mkulu-mphamvu, wandiweyani-khoma, lalikulu. -kakulidwe amakona anayi chitsulo chitoliro, chipinda kutentha Intaneti mosalekeza akamaumba luso luso, ndalama, ndipo pali ngozi zambiri, ndipo motero zigawo zambiri zotere mu zomangamanga zitsulo anayenera ankaitanitsa kuchokera kunja, kuletsa chitukuko cha zitsulo zomanga China.Chachiwiri, amakona anayi zitsulo chitoliro mamembala zitsulo nayenso anakumana ndi vuto la kufewetsa mkulu-kutentha, ziribe kanthu nthawi zimene ayenera kukhala mankhwala moto, mbali imeneyi yawonjezera katundu ndi mtengo wa polojekiti, komanso mlingo wina wa chikoka cha phwando zitsulo chubu mawonekedwe okongola zithunzi zotsatira.

Yaikulu-kakulidwe mkulu mphamvu ndi mkulu zivomezi kumasulira mkulu moto zosagwira nyengo wandiweyani-mipanda ozizira mawonekedwe amakona anayi zitsulo chitoliro kudzaza mipata m'munda wa zoweta zomangira.Kotero kuti mtundu watsopano wa gawo la mtanda, zigawo zazitsulo za zinthu zatsopano zimatha kugwiritsidwa ntchito kwambiri kumalo osungiramo masewera, mabwalo a masewera, malo a msonkhano ndi zina zopangira malo ndi dongosolo la truss, zomwe zimagwiritsidwanso ntchito m'zaka zaposachedwa, kuwuka kwa chitsulo. dongosolo zogona adzakhala bwino kulimbikitsa ozizira kupanga zitsulo structural kusintha, ndi kulimbikitsa chitukuko cha nyumba zitsulo.
