Yas Tebchaws Yawg Lub Chaw Nyob, Ib qho kev sib hwm hauv cov chaw sib tw niaj hnub, AMPHECEATERS, thiab cov kws kho mob rau pej xeem, kev sib txuam, thiab ib puag ncig kev yoog. Lub hom phiaj tseem ceeb yog kom muaj kev nyab xeeb thiab durability thaum tseem muaj kev nplij siab thiab pheej yig, ntsib cov neeg xav tau ntawm cov neeg coob coob.
Hais txog cov khoom xaiv, cov pob yas cig councalicing feem ntau siv cov tshuab plastics xws li high- qhov ceev polyethylene (HDPE) lossis polypropylene (PP). Cov ntaub ntawv no muaj kev cuam tshuam zoo heev, huab cua kuj tsis kam, thiab nag, tsis txhob muaj cov teeb meem xeb thiab cov teeb meem ntawm cov hlau. Tsis tas li ntawd, yas yog lub teeb ci, ua kom yooj yim rau nruab thiab tswj hwm, thaum tseem txo cov nqi thauj mus los.
Nyob rau hauv cov nqe lus ntawm cov qauv tsim qauv, rooj zaum yuav tsum tiv thaiv ob qho tib si kev cuam tshuam (xws li kev cuam tshuam ntawm cov spectators nce thiab zaum) thiab lub siab ntawm lub caij nyoog zoo li qub txav). Engineers Siv cov qauv kev tshawb xyuas zoo rau kev ua kom lub rooj zaum zoo ntawm cov ntsiab lus tseem ceeb ntawm lub rooj zaum ntawm lub rooj zaum thiab rov qab). Tsis tas li ntawd, cov rooj zaum feem ntau tsim nrog kev txhawb nqa tav lossis hollow qauv hauv qab los txo qhov hnyav thaum ua kom nruj. Qee qhov siab -} kawg rooj tseem tseem yog cov qauv tsim qauv, tso cai rau kev sib dhos sai thiab cuam tshuam rau kev ua kom muaj ntau qhov chaw.
Ergonomics yog qhov kev txiav txim siab tseem ceeb hauv kev tsim qauv ntawm cov rooj tshiab. Lub rooj zaum recline ru tsev kaum sab xis (feem ntau 5-10 degrees), qhov tob (kwv yees li 40-45 cm), thiab cinrest curvature yog ua tib zoo xav rau ncua lub sij hawm zaum. Tsis tas li ntawd, rooj tog zaum rooj yuav tsum ua raws cov kev cai khiav tawm thiab tso cai rau kev ua ywj pheej kom tsis txhob muaj neeg coob.
Thaum kawg, ib puag ncig kev hloov kho kom muaj cov rooj kom muaj qhov tsis yog - Setardancy (kom tau raws li cov qauv kev nyab xeeb), thiab muaj kev ruaj khov hauv huab cua sov. Qee qhov kev tsim qauv kuj tseem sib xyaw ua ke nrog cov qhov kom tiv thaiv los ntawm cov dej nag.
Hauv cov ntsiab lus, cov qauv tsim ntawm cov rooj yas ua kom sib xyaw ua ke thiab kev txiav txim siab kev xav. Los ntawm cov khoom tsim kho tshiab thiab kev ua kom zoo, lawv ua kom muaj kev sib npaug ntawm tus nqi tswj hwm thiab ua haujlwm zoo, ua rau lawv tsis tseem ceeb ntawm cov chaw pej xeem.
