Umuyoboro wa portal ni icyuma gisanzwe cyicyuma kigizwe nurwego rwikariso, inkunga yambukiranya, guhuza inkoni, ikibaho cya buckle ikibaho cyangwa ikariso itambitse, ukuboko gufunga, nibindi, hanyuma bigashyirwaho inkoni ikomeza itambitse, guhuza umusaraba, inkoni yohanagura, inkoni ifunga, bracket na base, kandi ihujwe nuburyo bukuru bwinyubako ukoresheje urukuta ruhuza ibice. Umuyoboro wicyuma wicyuma ntushobora gukoreshwa gusa nkibisohoka hanze, ariko kandi nkibisanzwe imbere cyangwa byuzuye.

intego

1. Ikoreshwa mugushigikira igisenge mubikorwa byinyubako, salle, ibiraro, viaducts na tunel cyangwa nkibikoresho nyamukuru byo kuguruka.

2. Kora gride yimbere ninyuma yinyubako ndende.

3. Urubuga rwimuka rwimuka rwo gushiraho amashanyarazi, gusana hull nibindi bikorwa byo gushushanya.

4. Uburaro bwigihe gito, ububiko cyangwa inzu yakazi birashobora gushingwa ukoresheje portaf scafold hamwe nigitereko cyoroshye cyo hejuru.

5. Byakoreshejwe mugushiraho inzu yigihe gito na grandstand

Scafold yihuta ifite ibiranga gusenya byoroshye, ubwikorezi bworoshye hamwe nisi yose. Kubwibyo, ikoreshwa cyane mubushinwa. Muri scafold engineering, imikoreshereze yayo irenga 60%. Nibikoreshwa cyane kandi bikoreshwa cyane muri iki gihe. Nyamara, ubu bwoko bwa scafold bufite umutekano muke hamwe nubwubatsi buke, kandi ntibushobora guhaza ibikenewe byiterambere ryimishinga yo kubaka imari.

Hano haribisobanuro byinshi nubunini bwibice byingenzi

Hano haribisobanuro byinshi nubunini bwa portaf scafolds kwisi yose, harimo ibice mpuzamahanga nibice byo gupima mubwongereza. Kurugero, ubugari bwa 1219 portal frame mugice cyicyongereza ni 4 '(1219mm) naho uburebure ni 6 ′ (1930mm), naho ubugari bwa 1219 portal frame mubice mpuzamahanga ni mm 1200 naho uburebure ni mm 1900. Ubugari bwa gantry bwamasosiyete ya scafold yo hanze arimo 900, 914, 1200 na 1219 mm. Hariho ibipimo byinshi byuburebure bwa gantry, bikora sisitemu.

Ibicuruzwa byerekana ibicuruzwa byinshi mubushinwa nabyo ntibihuye cyane. Bamwe bigana ibicuruzwa byo hanze bisobanura, kandi ibice bimwe byubushakashatsi bwo murugo bishushanya sisitemu yonyine. Bamwe bemera ubunini bwabongereza abandi bakemera ubunini bwurwego mpuzamahanga. Kurugero, ubugari bwa gantry ni 1219mm muri sisitemu yicyongereza, 1200mm muri sisitemu mpuzamahanga yibice, naho intera ikozwe ni 1829mm na 1830mm. Bitewe nibi bipimo bitandukanye, gantry ntishobora gukoreshwa kuri mugenzi we. Nkurundi rugero, hari uburebure burenga umunani bwihariye nubunini bwa gantry, kandi hariho nubunini butandukanye hagati yimipira ihuza, bivamo ibisobanuro byinshi nubwoko butandukanye bwambukiranya diagonal.

Nubusanzwe kubera ubwinshi bwubunini dukeneye inganda zikomeye nkatwe kugirango zuzuze ibisabwa bitandukanye byabakiriya. Murakaza neza kubaza, nyamuneka twohereze imeri kubisobanuro birambuye.
