Shanghai Qinkai Industry Co., Ltd. Yatanze imibare ihanitse y'inkunga y'imitingito ku mushinga w'Ingoro z'Ubutabera za Mutagatifu Lucia

CASTRIES, St. Lucia na SHANGHAI, mu Bushinwa — Mu iterambere rikomeye ry’ibikorwa remezo bya Karayibe n’umutekano rusange, Shanghai Qinkai Industry Co., Ltd., ikigo gikomeye ku isi mu gukora no gushushanya imicungire y’insinga n’uburyo bwo gushyigikira imitingito, cyatanze raporo yuzuye y’igishushanyo mbonera cy’inkunga n’ibarura ry’umushinga w’icyubahiro wa St. Lucia Halls of Justice (HOJ). Igaragaza ubuhanga bukomeye mu by’ikoranabuhanga, imibare y’imitwaro, n’igenzura ry’umutekano w’imiterere byakozwe ku buryo bwo gushyigikira imitingito bwahagaritswe mu kigo cy’amategeko cy’ingenzi. Iki cyemezo cy’imiterere ni intambwe ikomeye, igamije kwemeza ko ibikorwa remezo by’ingenzi byo gukwirakwiza amashanyarazi mu kigo cy’ubutabera cy’ibanze cya St. Lucia bishobora kwihanganira ingaruka z’imitingito no gukomeza gukora mu gihe cy’ibibazo byihutirwa.

Uruhare rw'ingenzi rw'ubuhanga mu by'imitingito mu bikorwa remezo bya leta

Inyubako za leta n'iz'ibigo bigezweho zisaba ibirenze ubwiza n'ubuziranenge bw'ibanze bw'inyubako; zisaba imbaraga zo guhangana n'imitingito mu buryo bworoshye. Ibi ni ukuri cyane cyane ku bigo by'ubutabera, by'ubuyobozi, n'ibyihutirwa nka St. Lucia Halls of Justice, bikorera nk'ibigo by'ingenzi by'imitsi ku buyobozi bw'ibanze. Mu turere dukunze kwibasirwa n'ibikorwa bya geologiya, kurinda ibice bitari imiterere—nk'amasahani y'insinga afite amashanyarazi make n'amashanyarazi menshi, imiyoboro y'amazi, na sisitemu za HVAC—ni itegeko ry'ibanze ry'umutekano.

Mu gihe cy'umutingito, ibikoresho bidafite ingufu cyangwa byapimwe nabi bishobora guhinduka cyane, bigatera kwangirika kw'inyubako, ingufu z'amashanyarazi zigacika, ndetse n'akaga gakomeye ku bagituyemo. Sisitemu zishyigikira imitingito zihagaze zikora nk'inkingi zikomeye zigenzura ingendo zo ku ruhande n'iz'uburebure, zigakwirakwiza imizigo ihindagurika mu buryo butekanye mu nyubako ya mbere ya sima.

Kugira ngo habeho ibi bipimo by'umutekano bikomeye, Shanghai Qinkai Industry Co., Ltd. yashyize mu bikorwa ibipimo ngenderwaho by'imiterere mpuzamahanga n'iy'igihugu. Ibipimo ngenderwaho by'ubuhanga mu mushinga wa HOJ birimo:

• GB50017-2003: Amategeko agenga igishushanyo mbonera cy'inyubako z'icyuma
• GB50009-2001: Kode y'igishushanyo mbonera cy'imizigo y'inyubako
• JGJ145-2013: Amategeko Tekiniki yo Gushyiraho Inyubako za Beto Nyuma yo Kuzishyiraho
• GB50303-2002: Itegeko ryemerera Ireme ry'Ubwubatsi bw'Imishinga y'Ubwubatsi bw'Amashanyarazi
• 03S402 & 03SR417-2: Ibikoresho byo gushyigikira imiyoboro yo mu nzu n'amabwiriza yo kuyishyiraho

Aya mategeko agenga ihitamo ry'ibikoresho, imipaka yemewe y'umuvuduko, ibintu by'umutekano, n'ibipimo byo kuyobya kuri sisitemu zihagaze, bigenzura ko buri gice cy'amakuru gikozwe neza kandi gifite umutekano udasanzwe.

Ibisobanuro bya tekiniki n'igishushanyo mbonera cy'aho inkingi zihurira

Itsindasisitemu yo gushyigikira imitingitoYagenewe Ingoro z'Ubutabera za Mutagatifu Lucia ikoresha uburyo bwa multi-tier suspended bracket (ZJ-13 Bracket) kugira ngo itunganye kandi ishyigikire ubwoko butandukanye bw'udusanduku tw'amashanyarazi. Igishushanyo mbonera cyayo gikubiyemo imiyoboro y'amashanyarazi ifite voltage nkeya n'ifite voltage nyinshi inyura ku gisenge cy'ikigo.

Ibipimo by'umutwaro w'agasanduku k'insinga

Imibare ishingiye ku bipimo bikurikira by’umutwaro ugororotse munsi y’intera isanzwe y’inkunga ya metero 1.5:

1. Udusanduku tw'insinga dufite voltage nkeya:
   • 100×100 mm (12 kg/m)
   • 200×100 mm (22.5 kg/m)
   • 300×50 mm (20 kg/m)
   • 300×100 mm (40 kg/m)
2. Udusanduku tw'insinga dufite voltage nyinshi:
   • 100×100 mm (16 kg/m)
   • 200×100 mm (32 kg/m)
   • 300×50 mm (30 kg/m)
   • 300×100 mm (55 kg/m)
   • 400×150 mm (85 kg/m)

Igipimo cy’umutekano cya 1.2 gikoreshwa ku bice byose by’imizigo kugira ngo harebwe ihindagurika ry’ingufu n’izamuka ry’insinga mu gihe kizaza.

Imiterere y'Inteko Ishinga Amategeko

Iteraniro ry'ibanze rikoresha icyuma cya U-slot cya 41 × 41 mm (umuyoboro wa strut) gikozwe mu cyuma cy'imiterere ya karuboni cya Q235 cyiza cyane, gishyizwe mu nkoni za M10 na bolts z'inkingi zishyirwa mu gisenge cya beto.

Hasi hari ishusho irambuye y'igishushanyo cy'ikoranabuhanga kigaragaza ingano nyayo, intera, n'ibikoresho byo gufata byakoreshejwe muri ZJ-13 Suspended Seismic Support:

Nkuko bigaragara ku Ishusho ya 1, imiterere y'urupapuro rwo guhagarara ifite ibyiciro bitatu by'imirongo ya U ya 41 × 41 mm ifite uburebure bwa mm 600 ku ruhande n'intera y'aho ruhagarara ya mm 550. Igabanuka rihagaze rihambiriye neza hejuru ya beto hakoreshejwe bolts za beto za M10 × 80 na adaptateri za M10. Imirongo ya M10 yo guhagarara cyane ihuza imirongo myinshi, ifunze hamwe n'uduti twa M10 tw'impande n'udupira twa M11 dufunganye, bitanga akazu gakomeye kandi kadahindagurika.

Ubwiza bw'ibikoresho: Umuyoboro wa Strut wa 41×41 mm

Urufatiro rw'inyuma rwa Qinkaisisitemu yo gushyigikira imitingitoni imiterere ya U-slot ya 41 × 41 mm. Shanghai Qinkai Industry Co., Ltd. ikora iyi miyoboro ya strut ikoresheje icyuma cyubatswe na karuboni Q235, ibikoresho bisanzwe mu nganda bizwiho uburinganire bwiza bwo gukomera, ubushobozi bwo kugenda, no gusudira.

Kugira ngo ikomeze igihe kirekire mu kirere cy’ubukonje n’ubushyuhe byo mu nyanja ya St. Lucia, iyi miyoboro y’amazi ihabwa ibikoresho byo kurinda ibyuma bigezweho, birimo Pre-Galvanized (Z275), Hot-Dip Galvanized (HDG), na Electroplated Zinc (EZ).

Ishusho ya 2 isobanura neza ubushobozi bwo kwihanganira ibintu, kurangiza kuboneka, n'ubwoko bw'ibikoresho bya mekanike bya Qinkai's 41×41 mm U-slot series (Item No. 004120 / TG-41 GI). Impande z'inyuma zahinduwe zifite imisenyiumuyoboroImiterere itanga ubushobozi bwo kudacika intege no gukomera cyane iyo ihujwe n'imiyoboro y'amazi, bigatuma ihuriro riguma rikomeye mu gihe cy'imitingito.

Kubara ibintu birangira n'imizigo y'imiterere

Ishingiro ry'incamake y'isesengura ry'imiterere y'icyuma ryibanda ku kugenzura ko imbaraga zigoramye, imbaraga zigabanuka, n'ihindagurika rya buri giti cy'icyuma gitambambuga kiri munsi y'umutwaro ntarengwa biri mu rugero rwemewe rw'icyuma cya Q235.
