Kanjani ukubala izitebhisi bebodwa

Ngaphambi kokuthi uqale ukufakwa ezitebhisini endlini yezwe noma ifulethi, udinga ukwenza ukubala nemingcele yayo eziyisisekelo, usebenzisa iziqondiso izinga lobuchwepheshe.

Zimbili izinhlobo isitebhisi: ngezinyathelo zabezhnymi futhi isikulufa.

Ngezansi indlela kanjani ukubala ngokugibela isitebhisi sokuphumelela kokubili zilwane.

Indlela ekubalweni izitebhisi nge izinyathelo zabezhnymi

Ukubalwa izitebhisi nge izinyathelo zabezhnymi eyenziwa mazinga alandelayo lobuchwepheshe:

- 15h30 esiteji ngokujwayelekile Ubukhulu, ngamanye amazwi, isinyathelo ukuphakama 15 cm, ububanzi - 30 cm;

- nemingcele oshiwo ngenhla avumela ukwenza isitebhisi izinyathelo nge mashi nokuchema isilinganiso amabili;

- ububanzi ezitebhisini kumele okungenani ibe eziyikhulu namashumi amabili ngamasentimitha;

- ububanzi pad Kumelwe kungabi ngaphansi kuka ububanzi izitebhisi;

- titepisi le mashi ngokuvamile zokhahlamba kusuka amahlanu nanhlanu.

Kodwa ngezinye izikhathi kukhona isimo lapho predetermined nemingcele lobuchwepheshe ayikwazi ukusetshenziswa ngenxa eziyinkimbinkimbi ukukhwezwa izitebhisi.

Kanjani ukubala isitebhisi kulesi simo?

Ngenxa yalesi simo, kukhona enye indlela kuhlaziywa izitebhisi nge izinyathelo zabezhnymi.

Ukuze usebenzise le ndlela, kumele uzijwayeze amagama alandelayo:

- ububanzi Nyathela - ibanga phakathi emaphethelweni ehola izinyathelo eduze futhi okhonjiswe «b» incwadi;

- yesikhuphukeli ukuphakama - ukuphakama phakathi izindiza of the izigaba ezimbili futhi luchazwa ngegama incwadi Latin «h».

Ukuze sithole ukuphakama nobubanzi esekelwe Inkulumo elandelayo:

2 x h + b = 60 - 65 cm

okungukuthi isamba kabili ukuphakama yesikhuphukeli ububanzi yimpandla kumelwe zisuke ayisithupha ukuba amahlanu nesithupha cm.

Futhi ingasetshenziswa kulesi sibalo izitebhisi ashiwo ezimbili izibalo, esimagama azikhulumele: "Izinsiza ifomula" futhi "ifomula ukuphepha".

"Ukunethezeka Formula" has abanesibalo ezilandelayo: bh = 12 cm.

"Umthetho ofingqiwe ukuphepha": b + h = 46 m.

Ngaphezu izibalo ezingenhla ukuze uthole okukhethwayo isitebhisi esizayo, kumele wena uholwe le mithetho elandelayo:

- ububanzi indiza ka izitebhisi ukuba hhayi ngaphansi kuka imitha elilodwa;

- uma isitebhisi izinyathelo ezingaphezu kwezintathu, khona-ke kumelwe ifakwe handrails;

- ibanga eliphakathi kodonga futhi izitebhisi akufanele kube engaphezu kwemihlanu - amasentimitha ayisithupha;

- umthwalo esiphezulu, okumele ukumelana isitebhisi - kusukela eziyikhulu namashumi ayisishiyagalombili ukuba namashumi amabili nambili, futhi umgoqo - hhayi amakhilogremu ngaphansi kwekhulu.

Indlela ekubalweni ezitebhisini Kuvunguza

izitebhisi Kuvunguza ngokuyinhloko asetshenziswa kulezo zindawo lapho udinga ukulondoloza indawo ewusizo.

Uma uthi nhlá, ukubala ezitebhisini Kuvunguza ubonakala nzima. Kodwa, noma kunjalo, kuba ngamandla wonke umuntu, ngisho nalabo abangebona okuhle kakhulu ngesikhathi izibalo.

Ngokucaca, indlela kuboniswa kanjani ukubala isitebhisi, okungukuthi nesikulufu, isibonelo esiwusizo.

Ngokushesha kumelwe kuphawulwe ukuthi ubukhulu elikhulu Kuvunguza ezitebhisini ububanzi kufanele kube 0.8 - 0.9 amamitha.

Kanjalo-ke, isibonelo, kubalulekile ukubala isitebhisi, kokuba ububanzi 0.85 metres uphinde uthele kancane ukuphakama 2.7 amamitha. Ngaphezu kwalokho, lokhu yokubeka isitebhisi kufanele abe ubukhulu ephakathi ye 0.25 metres, isigaba ububanzi - 0.2 m Ukuphakama elilodwa ithuba -. 2.05 m.

Okokuqala okudingekile ukunquma ubukhulu jikelele bese udweba wonke isakhiwo, kusukela nkulumo: 2 x 0.85 + 0.25 = 1.95 m.

E. ubukhulu Ubude yinani lika kabili isitebhisi ububanzi futhi ububanzi kwensika isikhungo.

Isidingo okuholela ukufaka omunye selilonke umbuthano ngokuvumelana la mazwi alandelayo: 0,85 / 2 + 0,25 / 2 = 0,55 m.

Lapho 0.85 - isinyathelo ububanzi, 0.25 - ububanzi kukholomu emaphakathi.

Umbuthano ewumphumela trajectory yokwenyuka womuntu.

Okulandelayo, nqumani indlela titepisi oyedwa ithuba ubuhlobo:

2 x 3.14 x 0,55 / 0,25 = 13.816

Lapho 3.14 - pi.

Imikiswe degrees 14.

Sabe ukubala ukuphakama izinyathelo: 2.05 / 14 = 14.64 cm.

Lapho 2.05 - ukuphakama ukujika olulodwa.

Ukucacisa inombolo inani izinyathelo ngokuvumelana isisho: 2.7 / 18.44 = 0.1464. Thina abopha ukuba 19.

In the isinyathelo sokugcina ngokwendlela indlela kanjani ukubala isitebhisi isikulufa mashi phambili yokugcina ukuphakama esiteji: 2.7 / 19 = 0.142 m.
