Sechishandiso chekubatsira chekuvaka, nhoroondo yezvikafu inogona kuteverwa kumashure ekare, uye yanga ichiramba ichishanduka uye ichivandudza mukuvaka kwazvino. Aya anotevera ndiwo akakosha mabviro uye kusimudzira kwe scaffolding:
Kwakabva yekare scaffolding
Scaffolding haisi yemazuva ano yakagadzirwa, uye nhoroondo yayo inogona kuteverwa kumashure kuWarring States Period. Chikafu chekare chakange chakaitwa nematanda, uye mapango acho akaitwa nematanda, uye chiyero chekumisa chakanga chisina kuderera pane teknolojia yemazuva ano. Scaffolding yakashandiswa pakuvaka madziro evhu nemadziro eguta muWarring States Period. Zvivako zvekare zvechiChinese, kusanganisira shongwe dzekare uye madziro eguta, zvese zvakavakwa zvine scaffolding. Tsanangudzo dzechikafu chekare dzinogona kuoneka mumadziro eguta rekare reHenan. Makomba emapuranga echikafu achiri kuchengetedzwa mumadziro, uye zvisaririra zvematanda zvinochengetwa mumakomba.
Iyo prototype yemazuva ano scaffolding
Mukutanga kwema1950, United States yakabudirira kugadzira portal scaffolding kekutanga. Yakakurumidza kusimudzirwa nekuda kwekuiswa kwayo nyore uye disassembly, kufamba kuri nyore, uye kuita kwakanaka kwekutakura mitoro. Mukutanga ma1960, nyika dzeEurope dzakaunzawo nekugadzira portal scaffolding, uye dzakagadzira portal scaffolding masisitimu akafanana neayo portal scaffolding chimiro.
Tsigiro yedzidziso uye hwaro hunoshanda
Muna 1976, Wood, Bruner, naRoss vakakwereta pfungwa yekugadzira zvivakwa kuti vatsanangure kuti vana vangapedza sei mabasa akaoma kunzwisisa kupfuura kugona kwavo kuzvimiririra vachibatsirwa nevanhu vane ruzivo rwakanyanya. Pfungwa iyi inotsigirwa nedzidziso yaVygotsky yenzvimbo yeproximal budiriro uye tsvakiridzo yechinyakare yekudzidzira basa.
Kuvandudzwa uye kushandiswa kwezvitsva scaffolding
Kubva kuma1980s, China yakaunza mhando dzakasiyana dzechikafu senge scaffolding yemasuwo uye cup-hook scaffolding kubva kunze kwenyika. Kubva kuma1990, mamwe makambani epamba akaunza tekinoroji yekune dzimwe nyika uye akagadzira zvakasiyana-siyana zvitsva, senge latch scaffolding, CRAB module scaffolding, disc scaffolding, etc. The disc-hook scaffolding yakatanga muma1990 uye yakatanga kushandiswa munzvimbo dzekuvaka muGuangdong, nyika yangu uye yakakurumbira zvishoma nezvishoma.
Yakasarudzika mabhenefiti eiyo disc-mhando scaffolding
Iyo disc-type scaffolding inoshandisa yakaderera-alloy simbi, iyo ine deformation resistance iyo iri 1.4 times iyo yecarbon structural simbi uye inodzivirira corrosion. Hukukutu hwayo hwekutakura mutoro hwakapetwa katatu pane hwechinyakare chikafu-chikafu, chine kugadzikana kwepamusoro uye mutengo wakaderera.
pfupiso
Scaffolding yakagadziridzwa kubva kune ekare zvivakwa zvemapuranga kusvika kune zvemazuva ano zvivakwa zvesimbi, uye yakave nehunyanzvi hwekuvandudza tekinoroji uye nerutsigiro rwedzidziso. Mabviro ayo anogona kuteedzerwa kumashure kuWarring States Period, ukuwo budiriro yemazuva ano scaffolding yakatanga muma1950s uye yakashandiswa zvakanyanya uye inoramba ichigadzirwa kutenderera pasirese.
