Spot supply nangula bawuti wophatikizidwa mbali zowotcherera zomata za nangula

Pamene zida zamakina zimayikidwa pamaziko a konkire, malekezero a J-woboola pakati ndi L a ma bolt amayikidwa mu konkire.

Mphamvu yamphamvu ya bolt ya nangula ndi mphamvu yachitsulo yozungulira yokha. Kuthekera kovomerezeka kwapang'onopang'ono pamapangidwe ndi gawo lophatikizana lomwe limachulukitsidwa ndi mtengo wovomerezeka wapakatikati (Q235B: 140MPa, 16Mn kapena Q345: 170Mpa).

Maboti a nangula nthawi zambiri amapangidwa ndi chitsulo cha Q235, chomwe chimakhala chosalala komanso chozungulira. Rebar (Q345) ili ndi mphamvu zambiri, ndipo sikophweka kupanga ulusi wopota wa mtedza kukhala wosalala komanso wozungulira. Kwa ma bolt osalala ozungulira, kuya kokwiriridwa nthawi zambiri kumakhala kuwirikiza ka 25 m'mimba mwake, ndiyeno pangani mbedza ya digirii 90 yokhala ndi kutalika pafupifupi 120mm. Ngati bawuti awiri ndi lalikulu (mwachitsanzo 45mm) ndi kukwiriridwa kuya ndi kuya kwambiri, mbale lalikulu akhoza welded kumapeto bawuti, ndiye kuti mutu waukulu akhoza kupangidwa (koma pali zofunika zina). Kuzama kokwiriridwa ndi mbedza ndikuwonetsetsa kuti pali kukangana pakati pa bawuti ndi maziko, kuti asatulutse ndikuwononga bawuti.

Cholinga: 1. Fixed anchor bolt, yomwe imadziwikanso kuti short nangula bolt, imatsanuliridwa pamodzi ndi maziko kuti akonze zida popanda kugwedezeka kwamphamvu ndi mphamvu.

2. Boti ya nangula yosunthika, yomwe imadziwikanso kuti nangula wautali, ndi chingwe chochotsa, chomwe chimagwiritsidwa ntchito kukonza makina olemera ndi zida zokhala ndi kugwedezeka kwamphamvu ndi kukhudzidwa.

3. Zingwe za nangula zowonjezera nthawi zambiri zimagwiritsidwa ntchito kukonza zida zosavuta zokhazikika kapena zida zothandizira. Kuyika kwa mabawuti owonjezera a nangula kudzakwaniritsa zofunikira izi: mtunda wochokera pakati pa bawuti mpaka pamphepete mwa maziko suyenera kukhala wochepera ka 7 m'mimba mwake mwa mabawuti a nangula okulitsa; Mphamvu zoyambira pakuyika mabawuti okulirapo siziyenera kuchepera 10MPa; Sipadzakhala ming'alu pa dzenje lobowola, ndipo chisamaliro chiyenera kulipidwa kuti zisawonongeke kuti zisagwirizane ndi chitoliro cholimbitsa ndi kukwiriridwa mu maziko; Kubowola ndi kuya kwake kumagwirizana ndi bawuti ya nangula yakukulitsa.

4. Bondi la nangula ndi mtundu wa bawuti wa nangula womwe umagwiritsidwa ntchito kwambiri m'zaka zaposachedwa. Njira ndi zofunikira zake ndizofanana ndi za nangula wa nangula. Komabe, panthawi yolumikizana, tcherani khutu kuti muthamangitse ma sundries mu dzenje ndikupewa chinyezi.
