Makore Gumi eWenchuan Earthquake | Nzira yekuita sei Kusimbisa Kusimba?

Musi waChivabvu 12, 2008, kudengenyeka kwenyika kukuru kwe8.0-magnitude kwakaitika muWenchuan, Sichuan, China, uye kukanganisa kwakakura.

Gore rino rinocherechedza makore gumi kubva pakaitika Kudengenyeka kweNyika kuWenchuan. Hatina kumbokanganwa marwadzo ekufa. Nguva haina kumbobvira yachinja kune shamwari dzedu nenyika. Muna 512, zuva reChina rekudzivirira uye kuderedza njodzi, tinofanira kufungisisa nezvenguva yatinorangarira nekunamata. Kana imba yacho yakanaka zvakakwana, mugumisiro wacho uchava wakasiyana here?

Kusimbisa simbi kwakakosha mukuvaka, uye kusimbisa simbi yekubatanidza kunonyanya kukosha.

Takaita ongororo dzinoenderera, tsvakiridzo, kuyedza, uye yakasanganiswa ruzivo rwemushandisi mhinduro panzira dzekusimbisa simbi dziri kushandiswa pamusika wekuvaka. Takaona kuti kune nzira dzinoverengeka dzinowanzo shandiswa senge lap welding, flash welding, electroslag welding, pressure welding, uye screw connections. Munzira yekubatanidza yekusimbisa mbariro, nzira inopindirana ndeye nzira yekubvisa, uye chiyero chekukodzera cheflash welding ndiyo yakaderera, inenge chikamu chimwe muzvitatu chayo chisina kukodzera; iyo electroslag welding nguva dzakaderera, kunyanya mushure mekuchinjisa welding ye electroslag welding, chiyero chekukodzera chakaderera kwazvo, kazhinji Haikwanise kuita bvunzo dzebvunzo, chete iyo sleeve yekubatanidza nzira inogona kuwana 100% kupasa mwero.

Iko kusimba kwesimba, simba regoho uye zvimwe zvinongedzo zveakakwirira-simba seismic rebar maoko akakwira kupfuura aya eakajairwa anopisa-akakungurutswa ribbed rebars. Izvo zvakakodzera kuvakwa kwezvikuru-zvikuru zvezvirongwa zveveruzhinji zvakadai seyekumhanya-mhanya njanji uye simba remhepo, uye mhando nyowani dzezvivakwa zvekuvaka zvinokurudzirwa uye zvinoshandiswa nenyika.

Kune nzvimbo dzine kudengenyeka kwenyika, yakakwirira-yakasimba, yakakwirira-simba, yunifomu-elongation, yakakwirira-simba, seismic-yakasimbiswa simbi rebars inoshandiswa. Zvivako zvehurumende zvakaiswa mari neHurumende uye dzimba dzinodhura ndidzo dzakatanga kutora simbi dzakasimba zvikuru. Panguva imwecheteyo, kushandiswa kwepamusoro-simba resimbi yekusimbisa sleeve yekusimbisa hutano hwehutano, uye kushandiswa kwepamusoro-simba kusimbiswa kwesimbi sechirongwa cheimba mumaguta uye kumaruwa kuita mibairo yekuvaka imwe yemamiriro ekukurudzira kushandiswa kwesimbi yakasimba rebar.

Yakavambwa muna 1998, Hebei YiDa Rebar Connection Technology Co., Ltd. Iri bhizinesi rinozivikanwa muChinese kuvaka simbi yekusimbisa yekubatanidza indasitiri. Zvigadzirwa zvikuru zvekambani ndeizvi: marudzi akasiyana-siyana uye zvirevo zvesimbi yekubatanidza maoko, uye mhando dzakasiyana dzesimbi yekubatanidza simbi yekubatanidza michina nezvimwe zvine chekuita nazvo, zvinosanganisira simbi yekutenderedza muchina, simbi pombi threader, rolling musoro, rolling vhiri, peeling Rib blades, mechanical wrenches, torque wrenches, etc. huwandu hwekuita kwechigadzirwa zvinoenderana neJGJ107-2016 "General technical specification for reinforced mechanical connection" uye JGT163-2013 "rebar mechanical connection sleeve Izvo zvinodiwa necartridge.
