Mukupera kwema1960 uye kutanga kwa1970, nekuvandudzwa kwezvikamu zvidiki uye zvepakati zvakasimbiswa, huwandu hukuru hwemafekitori ezvikamu zvakafanogadzirwa hwakaonekwa mumaguta nekumaruwa.Hollow slab, flat plate, purlin uye inorembera tile plate yezvivakwa zvevagari;Denga remba, mahwendefa akaita F, mahwendefa emugero anoshandiswa muzvivakwa zveindasitiri uye mahwendefa akapetwa akaita seV uye mahwendefa echigaro anoshandiswa mumaindasitiri uye zvivakwa zvevagari zvave zvigadzirwa zvikuru zvemafekitori aya, uye indasitiri yezvikamu zvakafanogadzirwa yatanga kuumbwa.

Pakati pemakore ekuma1970, nekukurudzira kwakasimba kwemadhipatimendi ehurumende, nhamba huru yemafekitori makuru ekongiri uye mafekitori emagetsi emwenje akavakwa, izvo zvakakonzera kukwidziridzwa kweindasitiri yezvikamu zvakafanogadzirwa.Pakazosvika pakati pemakore ekuma1980, makumi ezviuru zvezvirimwa zvakafanogadzirwa zvehukuru hwakasiyana zvakatangwa mumaguta nemaruwa, uye kusimukira kwechikamu cheindasitiri yeChina kwakasvika pakakwirira.Panguva ino, mhando huru dzezvikamu zvakagadzirirwa ndezvinotevera.Civil building components: exterior wall slab, prestressed building slab, prestressed circular orifice plate, precast concrete balcony, etc. (sezvinoratidzwa mumufananidzo 1);

Zvivako zvekugadzira maindasitiri: crane danda, prefabricated column, prestressed roof truss, roof slab, denga remba, etc. (sezvinoratidzwa mumufananidzo 2);

Kubva pakuona kwehunyanzvi, kugadzirwa kwezvikamu zvakafanogadzirwa muChina kwakasangana nedanho rekusimudzira kubva pasi kusvika kumusoro, kubva pakunyanya manyorero kuenda kune mechanic kusanganisa, kuumbwa kwemuchina, uyezve kusvika kune yekugadzira mutsara wekugadzira ine dhigirii repamusoro rekugadzira mufekitori. .

Kubva kuma1990, makambani echikamu ave asina purofiti, mazhinji emafekitari makuru uye epakati nepakati mumaguta asvika pakusagadzikana, uye zvikamu zvidiki muzvivako zvevagari zvakapa nzira kukugadzirwa kwemafekitari madiki mumisha nemataundi. .Panguva imwecheteyo, yakaderera hollow slabs akagadzirwa nemamwe mabhizinesi emadhorobha akazadza musika wekuvaka, izvo zvakawedzera kukanganisa mufananidzo weindasitiri yezvikamu zvakagadzirirwa.Kubva kutanga kwa1999, mamwe maguta akatevedzana akaraira kurambidza kushandiswa kwe precast hollow floors uye kushandisa cast-in-situ kongiri zvivakwa, izvo zvave kukanganisa zvakanyanya kuindasitiri yezvikamu zvakagadzirirwa, iyo yasvika padanho rakaoma rehupenyu uye. rufu.

Muzana ramakore re21, vanhu vakatanga kuona kuti iyo cast-in-situ dhizaini sisitimu haichaenderane zvizere nezvinodiwa zvebudiriro zvenguva.Kune iri kuramba ichikura musika wekuvaka muChina, izvo zvakaipa zvecast-in-situ chimiro system zvinowanzove pachena.Mukutarisana nezvinetso izvi, pamwe chete neruzivo rwakabudirira rwekugadzirwa kwedzimba dzekune dzimwe nyika, indasitiri yekuvaka yeChina yatanga zvakare mafungu e "kuvaka maindasitiri" uye "maindasitiri edzimba", uye kuvandudzwa kwezvikamu zvakafanogadzirwa kwapinda muzera idzva.

Mumakore achangopfuura, pasi pekutungamirwa kwemitemo yakakodzera yemadhipatimendi ehurumende, mamiriro ekusimudzira ekuvaka maindasitiri akanaka.Izvi zvinoitawo kuti mapoka, mabhizinesi, makambani, zvikoro uye masangano ekutsvagisa sainzi awedzere kufarira kwavo kutsvaga kwezvikamu zvakafanogadzirwa.Mushure memakore ekutsvakurudza, vakawanawo zvimwe zvibereko.
