Kodi kuwerengera masitepe paokha

Musanayambe kuika staircase mu dziko nyumba kapena nyumba, inu muyenera mawerengedwe a magawo amafotokoza, ntchito mfundo luso malamulo.

Pali mitundu iwiri ya makwerero: ndi masitepe zabezhnymi ndi wononga.

Pansipa pali njira mmene kuwerengera makwerero a mitundu onse.

Njira ya mawerengedwe masitepe ndi masitepe zabezhnymi

Mawerengedwe a masitepe ndi masitepe zabezhnymi kuchitika ndi kutsatira luso:

- 15h30 siteji ambiri ndi miyeso, i.e., sitepe kutalika 15 cm, m'lifupi - 30 cm;

- tatchulawa magawo amalola kuti njira makwerero ndi ulendo kukondera mu chiŵerengero cha munthu awiri;

- m'lifupi staircase ndi ayenera kukhala mazana makumi awiri chimodzi masentimita;

- m'lifupi PAD ayenera kukhala osachepera m'lifupi masitepe;

- chiwerengero cha masitepe mu kuguba zambiri ranges ku asanu ndi khumi ndi asanu.

Koma nthawi zina pamakhala zochitika kumene anakonzeratu magawo luso sangathe ntchito chifukwa cha zovuta wokwera masitepe.

Kodi kuwerengera makwerero mu nkhani iyi?

Pakuti Pankhaniyi, pali njira ina kwa kuwerengetsa masitepe ndi masitepe zabezhnymi.

Kugwiritsa ntchito njira imeneyi, muyenera mutidziwe ndi terminology zotsatirazi:

- ndi kuyenda m'lifupi - mtunda pakati m'mbali yaikulu ya masitepe moyandikana ndi amaimira «b» kalata;

- riser kutalika - kutalika pakati pa ndege la magawo awiri ndipo amaimira Latin kalata «H».

Kudziwa kutalika ndi m'lifupi zochokera mawu otsatirawa:

2 × H + B = 60 - 65 masentimita

Ie Uwerenge kawiri kutalika kwa riser ndi kuyenda m'lifupi ayenera kukhala wochokera makumi asanu ndi masentimita makumi asanu ndi limodzi.

Komanso akhoza kugwiritsidwa ntchito mu mawerengedwe masitepe ndi mawu awiri masamu, amene maina zikuyendera: "zogwiritsa ntchito chilinganizo" ndi "chitetezo chilinganizo".

"Amatonthoza chilinganizo" ali chiwerengero zotsatirazi: bh = 12 cm.

"Chilinganizo chitetezo": b + H = 46 m.

Kuwonjezera kuwerengetsera pamwamba kuti muwone tsogolo makwerero, inu ayenera kutsatira malamulo otsatirawa:

- m'lifupi ndege masitepe kukhala osachepera mita imodzi;

- ngati makwerero ndi masitepe oposa atatu, ndiye ayenera akhale okonzeka ndi handrails;

- mtunda pakati pa khoma ndi masitepe sayenera oposa asanu - sikisi masentimita;

- katundu pazipita, amene ayenera kulimbana makwerero - kuchokera zana makumi asanu ndi atatu ndi mazana awiri mphambu makumi awiri, ndi chipongwe - osachepera zana makilogalamu.

Njira ya mawerengedwe a staircase mwauzimu

masitepe mwauzimu ali makamaka ntchito m'madera amenewa zimene mukufunika kupulumutsa malo abwino.

Koyamba, ndi mawerengedwe a staircase mwauzimu akuoneka zovuta. Koma, koma, ndi mphamvu ya aliyense, ngakhale amene sali wabwino kwambiri pa masamu.

Chifukwa ndi losavuta kumva, njira kumaonekeranso mmene kuwerengera makwerero, ndicho ndi wononga, chitsanzo chenicheni.

Nthawi yomweyo ayenera kutchula kuti kukula akadakwanitsira a mwauzimu staircase m'lifupi akhale 0,8 - 0,9 mamita.

Ndipo Mwachitsanzo, m'pofunika kuwerengera makwerero, ndi m'lifupi mamita 0,85 ndi msinkhu wa mamita 2,7. Ndipotu, pachithandara makwerero ayenera awiri chapakati mamita 0,25, m'lifupi siteji - 0.2 mamita Msinkhu wa Poyankha wina -. 2,05 m.

Choyamba kofunika kudziwa awiri akukhudzidwira ndi jambulani dongosolo lonse, ndi mawu akuti: 2 × 0.85 + 0,25 = 1.95 m.

E. Total awiri ndi Uwerenge awiri makwerero m'lifupi ndi m'mimba mwake wa pakati chipilala.

Kufunika chifukwa amaika circumference wina bwalo monga mwa mawu awa: 0,85 / 2 + 0,25 / 2 = 0,55 m.

Kodi 0,85 - sitepe m'lifupi, 0,25 - awiri a ndime chapakati.

Bwalo chifukwa ndi njira yodutsamo chikweza anthu.

Kenako onani nambala ya masitepe kuti nthawi imodzi mgwirizano wa:

2 × 3,14 × 0,55 / 0,25 = 13.816

Kodi 3,14 - PI.

Anamaliza digiri 14.

Ndiye ife kudziwa kutalika kwa mapazi a: 2.05 / 14 = 14.64 cm.

Kodi 2,05 - kutalika kwa iwonso limodzi.

Kudziwa chiwerengero cha masitepe monga akuti: 2.7 / 18.44 = 0.1464. Ife adzakhale mpaka 19.

Mu sitepe otsiriza malingana ndi njira mmene kuwerengera makwerero wononga ulendo patsogolo chomaliza gawo kutalika: 2.7 / 19 = 0.142 m.
