Chilimwe chilichonse, pafupifupi milungu iwiri msasa usanayambe, wina amapeza vuto.

Kuyenda kokonza zinthu kukuwonetsa mng'alu womwe uli m'bwalo lapamwamba la bedi lothandizira. Boluti yoteteza yatuluka m'bowo lake. Utoto wa ufa womwe unali pa gulu la chaka chatha ukuwonetsa kale mawanga a dzimbiri mozungulira ma weld chifukwa wogulitsayo adagwiritsa ntchito kumaliza kwa gawo limodzi m'malo mwa maziko oyenera a epoxy.

Woyang'anira msasa akutcha wogulitsa woyamba. Wogulitsayo akuti mabedi amenewo anali "oyenera kukhala m'nyumba" ndipo sagwiritsidwa ntchito pamalonda. Mtengo wosintha ndi katatu kuposa womwe adalipira. Ndipo tsopano pali anthu 60 ogona m'misasa omwe akufika m'masiku 10.

Izi si zongopeka. Ndamvapo nkhani kuchokera kwa ogwira ntchito m'misasa, oyang'anira mahosteli, ndi oyang'anira malo m'makontinenti atatu. Chifukwa chachikulu nthawi zonse chimakhala chimodzimodzi: kugula malo ogona m'nyumba kumaonedwa ngati mipando, pomwe ziyenera kuonedwa ngati zomangamanga.

Ngati mumagula mabedi kamodzi pa zaka 10-15 zilizonse pa malo omwe amagona anthu mazana ambiri pa nyengo iliyonse, masamu amasintha. Umu ndi momwe mungachitire bwino.

Chimene Chimasiyanitsa Mabedi a Bunk a Zamalonda ndi Zinthu Zomwe Zili mu Kabukhu ka Sitolo ya Zipando

Lowani mu sitolo iliyonse ya mipando yayikulu ndipo mupeza mabedi achitsulo okhala ndi mabedi $.$ Amaoneka ngati ofanana — awiri pamwamba pa awiri, chimango chopakidwa ufa, makwerero ophatikizika. Koma ikani ana azaka 12 pa iwo kwa milungu isanu ndi itatu yotsatizana ndipo kusiyana kwake kumawonekera mwachangu.

Mabedi amalonda ogulira m'misasa yogulitsa amamangidwa mosiyanasiyana. Zigawo za chimangocho zimakhala zokhuthala — nthawi zambiri mapaipi achitsulo a 1.5″ mpaka 2″ kapena chitsulo cha ngodya, osati chubu chopyapyala cha khoma la 1″ chomwe chimagwiritsidwa ntchito m'mabedi okhalamo. Zolumikizira zimalumikizidwa mokwanira, sizimangiriridwa pamodzi ndi mtedza wa m'migolo womwe umamasuka pansi pa mphamvu yosinthika. Ufa wa ufa ndi epoxy-polyester hybrid yomwe imagwiritsidwa ntchito pa ma microns 60–80 pambuyo pa phosphate pre-treatment, osati polyester imodzi yokha yomwe imapopedwa pachitsulo chopanda kanthu.

Kulemera kwake kukufotokoza theka la nkhaniyi. Bulangeti lachitsulo lokhala ndi zipinda ziwiri lokhalamo limalemera pafupifupi mapaundi 80–100. Chofanana ndi cha malonda chimalemera mapaundi 140–180. Kulemera kowonjezerako ndi chitsulo komwe kuli kofunika: m'zipilala zamakona, zitsulo zochirikiza zazitali, matiresi opingasa, ndi malo olumikizira makwerero.

Chitsulo Choyezera, Kulumikiza, ndi Kumaliza Komwe Kupulumuka Chotsukira Majeremusi

Malo okhala m'misasa ndi ovuta kwambiri pa mipando. Mabedi amasunthidwa pakati pa zipinda panthawi yopuma pantchito. Ana amawadumphira, amapachika zitsulo zoteteza, ndipo nthawi zina amawakoka pansi pa konkire. Ogwira ntchito yokonza zinthu amawapukuta ndi zotsukira zopangidwa ndi bleach pakati pa nthawi yopuma. M'nyengo yozizira, madzi amaundana pa chitsulo chozizira usiku wonse.

Zinthu zinayi zomwe zimatsimikizira ngati mabediwo apulumuka chaka chachisanu:

Kukhuthala kwa chitsulo. Chimango chiyenera kukhala makulidwe a khoma osachepera 1.5mm pa ziwalo zazikulu (zipilala zamakona, zitsulo zam'mbali). Zipilala zopingasa ndi zomangira zimatha kukhala 1.2mm. Chilichonse choonda ndipo mudzapeza kusinthasintha kwa chimango, kenako kutopa kwa weld, kenako kulephera kwakukulu - nthawi zambiri pomwe chothandizira chapamwamba chimakumana ndi chipilala chamakona.

Ubwino wa weld. Yang'anani ma weld okhazikika a MIG pa malo onse olumikizirana, osati ma weld okhazikika okhala ndi zokongoletsa. Ma weld okhazikika amaika mphamvu pamalo olumikizirana. Weld yokhazikika imagawa katundu kudzera mu cholumikizira chonse. Funsani wogulitsa kuti akupatseni chithunzi chapafupi cha weld ya ngodya yochokera kumbuyo kupita kumbali pa chipangizo chomalizidwa. Ngati sakutumiza, ndiye kuti ndi chidziwitso.

Dongosolo la utoto wa ufa. Ufa wosakanizidwa wa epoxy-polyester, wogwiritsidwa ntchito mutatsuka zinc phosphate musanagwiritse ntchito, wothiridwa pa kutentha kwa 180–200°C. Kuphatikiza kumeneku kumakupatsani kukana mankhwala (pazinthu zotsukira), kukana UV (pamabedi pafupi ndi mawindo), komanso kukana kukhudza (pazinthu zina zonse). Funsani za mtundu wa utoto wa ma microns. Pansi pa ma microns 50, yembekezerani dzimbiri mkati mwa zaka ziwiri pamalo aliwonse okhala ndi chinyezi.

Malo olumikizirana pansi. Mabedi abwino kwambiri ogulitsa amakhala ndi zipewa zapulasitiki kapena za rabara pansi pa miyendo, osati zitsulo zopanda kanthu zomwe zimakhala pansi. Izi zimachotsa chitsulocho ku chinyezi cha pansi, zimachepetsa phokoso pamene mabedi akusunthidwa, ndipo zimaletsa kupukutidwa pang'onopang'ono kwa chitsulo chomwe chimatha kudutsa mu ufa pamalo olumikizirana.

ASTM F1427 ndi Miyezo Yachitetezo Yomwe Siyosankha

Ngati msasa wanu uli ku United States, ASTM F1427 ndiye muyezo wofunikira kwambiri pa chitetezo cha mabedi okhala m'nyumba. Imafotokoza kutalika ndi kutalika kwa malo otetezera, kusunga matiresi, kulimba kwa kapangidwe kake pansi pa katundu wosasinthasintha komanso wosinthasintha, komanso zofunikira pa chizindikiro cha chenjezo.

Zofunikira zazikulu zomwe kugula zinthu kuyenera kutsimikizira:

• Zoteteza mbali zonse ziwiri ya bedi lapamwamba (osati mbali yotseguka yokha). Chotetezera cha mbali ya khoma chiyenera kukhala chopitirira ndipo chikhale ndi mainchesi osachepera asanu pamwamba pa matiresi.
• Mpata wa Guardrail: Mipata yomwe ili mu chipinda chotetezera iyenera kukhala yaying'ono mokwanira kuti mutu usatsekedwe - palibe mpata woposa mainchesi 3.5.
• Kutalika kwa matiresi mpaka pa chipata chotetezera: Pamwamba pa chotchingira payenera kukhala mainchesi osachepera asanu pamwamba pa matiresi akamakanizidwa.
• Chilolezo cha denga: Malo pakati pa pamwamba pa matiresi apamwamba ndi denga ayenera kukhala osachepera mainchesi 30 kuti apewe kuvulala mutu akakhala pansi.
• Kutalikirana kwa makwerero: mtunda wofanana ndi kuya kochepa kwa poponda komwe kumakwanira phazi la mwana (nthawi zambiri kuya kwa poponda ndi mainchesi 3–4, mtunda wosapitirira mainchesi 12).
• Thandizo la Foundation: Nsanja ya matiresi iyenera kunyamula katundu wosasinthasintha wa mapaundi 400+ popanda kusintha kosatha (giredi yamalonda; ASTM yocheperako kwa ogula ndi yotsika).

Ngati mukugula kuchokera kwa ogulitsa akunja, funsani mwachindunji kuti: “Kodi chitsanzo ichi chikugwirizana ndi ASTM F1427-21e1?” Ngati akunena kuti “mabedi athu ndi otetezeka kwambiri” koma osatchula muyezo, kapangidwe kake sikadatsimikizidwe paokha.

Pa misasa yakunja kwa US, zofanana ndi izi ndi EN 747 (Europe), AS/NZS 4220 (Australia/New Zealand), ndi BS EN 747 (UK). Zofunikira zake ndi zofanana - fizikiki ya mwana wogwa kuchokera pabedi lapamwamba sikusintha malinga ndi ulamuliro.

Kugula Kwambiri: MOQ, Mitengo Zenizeni, ndi Zomwe Chidebe Chili Nazo
