Ungafungidzira here? "Chinhu chemuchadenga" chaimboshandiswa mumaroketi nemaburi emhepo chiri kunyora patsva nhoroondo yekusimbisa zvivakwa - zvirimesh yekabhoni fiber.

• Majini emuchadenga muma1960:

Kugadzirwa kwemaindasitiri kwefilamenti dzekabhoni fiber kwakaita kuti chinhu ichi, icho chakasimba zvakapetwa kapfumbamwe pane simbi asi chakareruka kakapetwa katatu pazvina, chiunzwe kuvanhu kekutanga. Pakutanga chaichengeterwa "masekta epamusoro" akadai sendege nemidziyo yemitambo yepamusoro, chairukwa pachishandiswa matekiniki echinyakare emachira, asi chaive nemukana wekushandura nyika.

• Chinjo huru mu "hondo pamusoro pesimbi":

Mesh yekusimbisa yakajairika yakafanana ne "codger yekare" yenyika yekuvaka: inorema seyenzou (inenge 25 kg pa square meter yemesh yekusimbisa), uye inotyawo munyu, mvura, nenguva - - Kukukurwa kwe chloride ion kunoita kuti simbi iwedzere kukura nekutsemuka.
Kubuda kwejira remambure ekabhoni fiberInoputsa zvachose dambudziko iri: kuburikidza nekuruka zvakananga + epoxy resin impregnation, inoita kuti ukobvu hwekusimbisa huve kubva pa5cm kusvika 1.5cm, huremu hwacho hunongova 1/4 ye rebar, asiwo hunodzivirira acid nealkali, mvura yegungwa, uye mukusimbiswa kwebhiriji mugungwa, hapana chiratidzo chekuora kwemakore makumi maviri.

Sei mainjiniya ari kumhanyira kuishandisa? Zvakanakira zvishanu zvakaoma zvakaburitswa pachena

kusimbisa:kuvakwa kunofanira kushandiswa kuenzana nepurasitiki! Dunhu rakashandiswa zvisirizvo, zvichiita kuti madhiramu asimbiswe uye adonhe — kungofanana nekushandisa guruu kunamira girazi, guruu harisi iro rakakodzera sekutambisa basa.

Kubva kuGuta Risingabvumidzwe Kuenda kuBhiriji reMhiri kweGungwa: Zviri Kuchinja Nyika Zvinyararire

• "Bhandiji Risingaonekwe" reNhaka Yetsika neZvivako Zvekare:

Chivako cheBeyer Bau, chivakwa chemakore zana chiri paTechnische Universität Dresden muGermany, chaida kusimbiswa nekukurumidza nekuda kwekuwedzera kwemitoro, asi chaive pasi pemitemo yaiiswa nekuchengetedzwa kwezviyeuchidzo. Mainjiniya ane jira re carbon fiber mesh rakakora 6mm + dhayamita yakatetepa, pasi pedanda "paste" dhayamita ye "transparent band-aid", kwete chete kuti kutakura mutoro kuwedzere 50%, asiwo hazvina kuchinja chivakwa nekutaridzika kwepakutanga, uye kunyange nyanzvi dzeHeritage Board dzakarumbidza: "Sezvakaita chivakwa chekare kuita ganda risina mavanga".

• "Super patch" yeinjiniya yemotokari:

Florida, United States, mabhiriji akayambuka gungwa, akasimbiswa nejira remachira ecarbon fiber muna 2003, simba rinobva ku "vasina simba" rakakwira ne420%, uye ikozvino makore makumi maviri gare gare, madutu achiri kugadzikana segomo riri pamhenderekedzo yegungwa. Purojekiti yeHong Kong-Zhuhai-Macao Bridge island tunnel, yakashandisawo chinyararire kuita kuvandudzwa kwechivako, kudzivirira kukanganiswa kwemvura yegungwa.

• "Chombo chemashiripiti chinodzosa zera" chechinhu chidiki chekare uye chakasakara:

Munharaunda yemakore ekuma1980 muBeijing, matombo epasi akatsemuka zvakanyanya, uye hurongwa hwekutanga hwaive hwekuputsa nekuvaka patsva. Gare gare nejira re carbon fiber mesh + polymer mortar reinforcement, mutengo pa square meter i200 yuan chete, pane kuvaka patsva kwe80% yemari yekuchengetedza, uye ikozvino vagari vanoti: "Inzwai imba iri mudiki nemakore makumi matatu!"
Ramangwana rasvika: Kuzvirapa, kutarisa "zvinhu zvakangwara" kuri kuuya

• "Chiremba anozvirapa" akagadzirwa nesimbi:

Masayendisiti ari kugadzira mesh yekabhoni fiber "inozviporesa" - kana maburi madiki akaitika muchivako, mesh iyi inogona kushandiswa sekusimbisa. - Kana maburi madiki akaonekwa muchivako, makapisi ari muchinhu ichi anoputika kuti abudise zvinhu zvinogadzirisa zvinozadza maburi acho otomatiki. Miedzo yakaitwa parabhoritari muUK yakaratidza kuti chinhu ichi chinogona kuwedzera hupenyu hwekongiri kusvika makore mazana maviri.

• "Chishongo chehutano" chezvivakwa:

inoisa ma sensor e fiber-optic mumesh yekabhoni fiber, se "wachi yakangwara" yezvivakwa: chivako chikuru muShanghai chinochishandisa kutarisa kugadziriswa kwezvivako nekutsemuka panguva chaiyo, uye data rinotumirwa zvakananga kuhofisi yekutarisira, iyo inoshanda ka100 kupfuura kuongororwa kwemaoko kwechinyakare. Inoshanda ka100 kupfuura kuongororwa kwemaoko kwechinyakare.
Mazano ekuchenjera kune mainjiniya nevaridzi
1. Zvishandiso zvinosarudza chakakodzera, zvakapetwa kaviri mhedzisiro nehafu yekuedza:ziva zvigadzirwa zvine simba rekudhonza ≥ 3400MPa uye modulus of elasticity ≥ 230GPa, uye unogona kukumbira vagadziri kuti vape mishumo yekuyedza.
2. Usave neusimbe pakuvaka:Nzvimbo yekumusoro inofanira kukweshwa yakachena, uye polymer mortar inofanira kusanganiswa zvichienderana nehuwandu hwayo.
3. Kugadziriswa kwechivako chekare kunokosha:Zvichienzaniswa nekuputsa nekuvakazve, kusimbiswa kwe carbon fiber mesh kunogona kuchengetedza chitarisiko chepakutanga chechivako, asiwo kuchengetedza mari inopfuura 60%.
Mhedziso
Apo zvinhu zvemuchadenga "zvakaburukira pasi" kumunda wekuvaka, takangoerekana tawana: kusimbiswa kwekutanga hakufaniri kuita mabasa makuru, chivako chekare chepakutanga chinogonawo kuva "kukura kwekudzokera shure".Jira remachira efaibha yekabhoniyakaita se "gamba guru" muindasitiri yekuvaka, ine hunhu hwakajeka, hwakasimba uye hunogara kwenguva refu, zvekuti chivako chega chega chekare chine mukana wekuvandudza hupenyu hwacho - uye izvi zvingangova kutanga kwekuchinja kwezvinhu.
