Rooj tog Screed eccentric hom - pros, cons, hauj lwm

Rooj tog Screed - ib tug me me iav xws li screws, uas yog siv nyob rau hauv qhov siv thiab ua cov rooj tog. Ntawm cov hoob kawm, yog tsis muaj lawv koj yuav tau teem lub rooj tog (nrog screws), tiam sis ntawm no nws yog tsim nyog los noj mus rau hauv tus account cov kev pab cuam ntawm lub ob ties. Firstly, nyob rau hauv sib piv rau nws tus kheej-drilling screws, rooj tog zaum, kaw xws mechanisms yuav saib ntau npaum li cas aesthetic, tsis muaj tej yam cim qhia ntawm fasteners.
Thiab secondly, bolts thiab screws yog haum limited siv, tsis tau hais tias hais txog cov rooj tog zaum npog, uas yuav tsum tau ntsia tau rau hauv tej yam ntawm cov rooj tog, txawm nyob rau hauv lub ces kaum version. Rau hnub tim, lub feem ntau txoj kev daws teeb meem nyob rau hauv lub teb ntawm accessories yog eccentric Screed. Yog li ntawd, cia saib nyob rau hauv nws lub ntsiab zoo thiab disadvantages.

Hauj lwm, yam ntxwv thiab qhov ntev

Eccentric rooj tog screeds yog ib tug 3-feem qauv uas muaj xws li tshwj xeeb racks, Fittings, thiab, tau, tus eccentric. Qhov no mechanism siv rau "evrovintov" hom thiab yog dav siv nyob rau hauv lub rooj tog kev lag luam. Cov cam yuav ua ob los ntawm hlau thiab los ntawm yas (nyob ntawm seb qhov ntxiv siv cov khoom thiab muab cov txee). Piv txwv li, rooj tog zaum rau hauv chav ua noj muaj heev dua lwm yam ntawm steel screws, tab sis tej khoom me me (xws li ib tug txee) yuav tau koom ua ke nrog yas mechanisms.

Nws yuav tsum tau muab sau tseg tias cov rooj tog sib raug zoo nyob rau hauv no txoj kev yog ib tug heev robust thiab txhim khu kev qha. Piv rau lwm cov kev xaiv screeds, cam mechanisms yog tau mas ntau mus ntawm los ua ke / disassembly ntawm cov rooj tog (tab sis tsis muaj ntau tshaj li tsib). Nyob rau hauv lub qhuav ntawm tag nrho cov qhov rau lub screws yog manufactured siv tshwj xeeb drilling thiab zoo machines, tab sis nyob rau hauv tsev yog txaus mus thov ib tug laum los yog ntswj ntsia hlau nrog ib tug tsim nyog nozzle. Lawv yog cov los ntawm txoj kev ib tug dog dig hexagon.

Nrog hais txog qhov luaj li cas, eccentric rooj tog ties yuav muab faib ua peb pawg, cov uas yog cov nram qab no ntau thiab tsawg pab: 7, 50, 7, 70, 5 50 millimeters. Nrog rau cov qhov ntev, thiab, ntawm chav kawm, tus tsim, lawv yuav tsum muaj ntaub ntawv rau yuav luag txhua hom ntawm cov rooj tog thaum twg lub kaum sab xis ntawm inclination. Qhov no feature yog ib txwm tus eccentric nyob rau hauv kev sib piv nrog screws thiab lwm yam kev ties. Nyob rau hauv feem ntau tus neeg mob, lawv muaj peev xwm constrict rooj tog zaum ntawm cov ces kaum ntawm 90, 135 thiab 180 degrees.

cons

Ntawm cov disadvantages ntawm no hom ntawm cable ties peev xwm yuav txawv nws cov high nqi, uas yog ob peb lub sij hawm siab tshaj tus nqi indices ntawm bolts thiab screws. Qhov thib ob drawback yog tias eccentric rooj tog ties tsis tso miscalculations. Yog hais tias cov nroj tsuag mechanisms los yog txiav txim tag nrho mus, ces nyob rau hauv tsev no khi yuav lwj lub rooj tog, yog hais tias tus miscalculation yog ntau tshaj li 5 millimeters.

Nyob rau hauv kev, txawm lub shortcomings, peb yuav hais tau tias eccentric rooj tog ties - lub feem ntau txhim khu kev qha thiab tov daim ntawv ntawm cov rooj tog los ua ke, uas kuj muaj ib tug zoo feem nyob rau hauv tus tsim ntawm cov khoom.
