Umkhiqizi othengisa ngqo i-turnbuckle scaffold Umkhiqizi
Incazelo Yomkhiqizo
>>>
I-turnbuckle scaffold iwuhlobo olusha lwe-scaffold, eyethulwa ivela eYurophu ngeminyaka yawo-1980. Kungumkhiqizo othuthukisiwe ngemuva kwesikafula sebhande lesitsha. Yaziwa nangokuthi i-chrysanthemum disc scaffold system, i-plug-in disc scaffold system, i-wheel disc scaffold system, i-buckle disc scaffold, ifreyimu yengqimba kanye nohlaka lwe-Leia, ngoba umgomo oyisisekelo we-scaffold wasungulwa yinkampani ye-layher eJalimane futhi ibizwa nangokuthi. "Leia uhlaka" ngabantu embonini. Isetshenziselwa ikakhulukazi ifreyimu yokukhanyisa kanye nohlaka lwangemuva lwekhonsathi yezinga elikhulu.), Isokhethi yalolu hlobo lwe-scaffold idiski enobubanzi obungu-133mm nogqinsi luka-10mm. Izimbobo ezingu-8 zisethwe kudiski φ 48 * 3.2mm, ipayipi yensimbi ye-Q345A isetshenziswa njengengxenye eyinhloko. Induku eqondile ihlanganiswe ne-disc njalo ngo-0.60m ubude obuthile bepayipi lensimbi. Le noveli nediski elihle lisetshenziselwa ukuxhuma induku yesiphambano ngomkhono wokuxhuma ngezansi. I-cross bar yenziwe ngepulaki enephinikhodi eshiselwe emaphethelweni womabili wepayipi lensimbi.
I-scaffold iyinkundla yokusebenza esungulwe ukuze kuqinisekiswe ukuqhubeka kahle kwenqubo ngayinye yokwakha. Ihlukaniswe i-scaffold yangaphandle kanye ne-scaffold yangaphakathi ngokusho kwendawo yokumiswa; Ngokwezinto ezihlukene, ingahlukaniswa ibe isikafula sokhuni, isikafula se-bamboo kanye nesikafula sepayipi lensimbi; Ngokwesakhiwo sesakhiwo, ihlukaniswe yaba isikafula sesigxobo esime mpo, isikafula sebhuloho, isikafula sengosi, isikafula esilengisiwe, isikafula esilengayo, isikafula se-cantilever nesikafula esikhuphukayo. Izikafula ngezinhloso ezahlukene zizokhethelwa izinhlobo ezahlukene zokwakha ubunjiniyela. Iningi lezisekelo zebhuloho zisebenzisa izikafula ezibopha izitsha, kanti ezinye zisebenzisa nezikafula zephothali. Iningi lezikafula zaphansi zokwakhiwa kwesakhiwo esikhulu zisebenzisa izikafula zokubopha, kanti ibanga elide lezigxobo zescaffold ngokuvamile liyi-1.2 ~ 1.8m; Ibanga eliphambeneyo ngokuvamile liyi-0.9 ~ 1.5m.
Uma kuqhathaniswa nesakhiwo esijwayelekile, izimo zokusebenza ze-scaffold zinezimpawu ezilandelayo:
1. Ukuhluka komthwalo kukhulu;
2. Ijoyinti yokuxhuma i-fastener i-semi-rigid, futhi ukuqina kwesihlanganisi kuhlobene nekhwalithi ye-fastener kanye nekhwalithi yokufaka, futhi ukusebenza kwesihlanganisi kuyahluka kakhulu;
3. Isakhiwo sezikafula kanye nezingxenye zineziphambeko zokuqala, njengokugoba kokuqala nokugqwala kwamalungu, iphutha elikhulu lokuma kwe-eccentricity, njll;
4. Ukuhluka okubophezelayo kwendawo yokuxhuma nodonga ku-scaffold kukhulu. Ucwaningo olumayelana nezinkinga ezingenhla alunakho ukuqoqwa okuhlelekile kanye nedatha yezibalo, futhi alunayo imibandela yokuhlaziya amathuba azimele. Ngakho-ke, inani lokumelana nesakhiwo eliphindwe nge-coefficient yokulungisa ngaphansi kuka-1 linqunywa ukulinganisa ngento yokuphepha eyamukelwe ngaphambilini. Ngakho-ke, indlela yokuklama eyamukelwa kulokhu kucaciswa i-semi probabilistic kanye ne-semi empirical empeleni. Kuwumbandela oyisisekelo wokuklama nokubala ukuthi isikafula sihlangabezana nezidingo zesakhiwo ezicaciswe kulokhu kucaciswa.
