Mwachidule
Chitsulo chosinthira ichi ndi cholumikizira chachitsulo cholowera / zogwiritsidwa ntchito konkriti zolimbitsa thupi ndikulimbikitsidwa. Amapangidwa kuchokera ku chitsulo chofatsa ndipo chimapatsidwa nthiti zabwino zomata kwa konkriti. Kuwonongeka kwa nthiti chifukwa cha gawo la nthiti, ndipo konkriti imatha kugwirizanitsa kwambiri, yomwe imapiriranso mphamvu zakunja. Bala yopunthidwa ndi ndodo yachitsulo, yokhazikika yolimbikitsira bala yachitsulo, ndipo itha kugwiritsidwa ntchito komanso zitsulo zitsulo. Maonekedwe a nthiti yotsekera ndi wozungulira, herringbone, wopangidwa ndi atatu. Direji mwa mwadzina mwa nyumba yopumirayo imafanana ndi mainchesi angapo a gawo lozungulira la gawo lofanana. Konkriti yolimbitsa konkriti mu kupsinjika kwakukulu.

Mitundu ya zotumphukira
Kutengera mtundu wa zinthu zomwe zimagwiritsidwa ntchito popanga, mitundu yosiyanasiyana ya zopaka zili
L 1. European Reprear
European Repluar imapangidwa ndi manganese, zomwe zimawapangitsa kuzimiririka mosavuta. Sayenera kugwiritsa ntchito madera omwe amakonda nyengo zochulukirapo kapena zotsatila, monga zivomezi, mkuntho, kapena zakumwa. Mtengo wa kubwezeretsa uku ndi kotsika.
l 2. Carbon Steel Reser
Monga momwe dzinalo likuyimira, limapangidwa ndi chitsulo cha kaboni ndipo limadziwika kuti wakuda bar chifukwa cha mpweya. Cholepheretsa chachikulu kwa kubwezeretsaku ndikuti chimachita bwino, chomwe chimapangitsa konkriti ndi kapangidwe kake. Chiwerengero champhamvu cha Tunsile chimaphatikizidwa ndi mtengo wake umapangitsa kubwezeretsa wakuda chimodzi mwazosankha zabwino kwambiri.
l 3. epoxy-opota
Kubweza kwa epoxy-kozizira ndikubwezeretsedwanso kwa chikhoto cha epoxy. Ili ndi mphamvu yomweyo yofanana, koma ili ndi 70 mpaka 1,700 nthawi yolimbana ndi kututa. Komabe, zokutidwa ndi epoxy ndizowoneka bwino. Chokulirapo kuwonongeka kwa zokutira, zosagwirizana kwenikweni ndi kutukuka.
l 4.
Kubwezeretsanso kwagalukirako kumakhala kovuta kwambiri kuposa kutukuka kuposa kubalanda kwakuda, koma ndizovuta kwambiri kuwononga zokutira za Galvanasid Renar. Mwakutero, ili ndi phindu kwambiri kuposa kutulutsa kwa epoxy-koterera. Komabe, ili ndi pafupifupi 40% yokwera mtengo kuposa epoxy-yopaka.
l 5. Phukusi lagalasi-fiber (GFRP)
Gfrp imapangidwa ndi kaboni. Monga momwe zimapangidwira ndi fiber, kukonzekera sikuloledwa. Zimakhala zolimbana kwambiri ndi kutukuka ndipo ndizokwera mtengo poyerekeza ndi zobwezera zina.
l 6. Chitsulo chosapanga dzimbiri
Kubwezeretsa kopanga dzimbiri ndikofunikira kwambiri kupezeka, pafupifupi zisanu ndi zitatu mtengo wa epoxy-yobweza. Ndinso rechar wabwino kwambiri pantchito zambiri. Komabe, pogwiritsa ntchito chitsulo chosapanga dzimbiri mu zonse koma zokhala ndi zovuta zambiri nthawi zambiri zimakhala zochulukirapo. Koma, kwa iwo omwe ali ndi chifukwa chogwiritsira ntchito, chitsulo chosapanga dzimbiri chobwezeretsa 1,500 nthawi zambiri chogonjetseka kuposa bar yakuda; Imakhala yolephera kuwonongeka kuposa mitundu ina iliyonse yopanda mphamvu kapena yopanda tanthauzo; Ndipo itha kukwiya m'munda.
