Deskripsyon
Konsèp nan twal asye soude / may te premye pwopoze an 1901, pandan y ap premye aplikasyon an pi gwo te nan 1908. Nan 1922, li te teste yo dwe materyèl la ase apwopriye pou wout nan trafik lou. Nan fen Dezyèm Gè Mondyal la, li te montre fòs li paske li mande mwens travay ak tan. Li te wè li kòm materyèl la pafè ranfòse ede Ewòp rebati apre lagè a. Anvan vire nan syèk la, li te aksepte kòm yon fòm solid nan ranfòsman konkrè nan bilding. Li te tou te jwi gwo itilizasyon nan lòt pwojè tankou pis aterisaj ayewopò ak yon kantite bilding inogirasyon achitekti.
Sa a ranfòsman soude fil may panno yo te fè nan ba asye striye estokaj atravè plas soude pou dal ak konstriksyon miray. Baton an asye striye yo itilize ka amelyore lyezon ak konkrè a epi minimize nenpòt fann konkrè ki ka rive kòm yon rezilta nan kontraksyon konkrè. Karakteristik sa a pèmèt may an asye striye soude lajman itilize kòm materyèl bilding pou ranfòse estrikti dal blòk, ak ranfòsman dal kre, ranfòsman miray bilding ak ranfòsman miray sipò. Nan itilizasyon pratik, li se souvan itilize ak chèz ba kòm sipò.
Materyèl ak Kalite:
Ribbed asye ba may ka divize an twa kalite dapre materyèl: Hot plonje galvanised, elektwo galvanised oswa asye pur. Li ka divize an de kalite selon gwosè ba asye yo itilize: kalite lou (dyamèt ba oswa baton 12mm minimòm) ak kalite limyè (dyamèt baton rebar soti nan 3mm jiska 10mm). Ribbed asye soude may ka divize an twou kare ak twou rektangilè selon kalite ouvèti yo.
