Screws rau wood: simplicity, kev cia siab, kav ntev

Nyob rau hauv nqa tawm kev tsim kho ua hauj lwm, kho ntawm cov rooj tog, li zoo raws li rau mounting ntau hom tsev décor khoom (duab, txee thiab thiaj li nyob. P.) Yuav tsis ua li cas tsis xws li ib tug tsim nyog tshaj plaws raws li ib tug self-tapping ntsia hlau. Muaj ob peb hom ntawm fastening cov cuab yeej, tab sis yog nws tus kheej-tapping screws rau cov ntoo, tej zaum, feem ntau siv daim ntawv no. Nws muab ib tug ruaj ntseg tsevneeg ntawm qhov chaw ua los ntawm cov ntoo los yog ntoo ntaub ntawv (chipboard, particle board, plywood), raws li zoo raws li rau fastening ntawm los xij ntawm plasterboard rau cov ntoo puag.

Nyob rau hauv tsos, cov self-tapping screws li. Tab sis txawv ntawm cov fasteners uas threaded rau ib tug 2/3 ntev, uas yog threaded raws lawv tag nrho ntev.

Lub ntsiab feature txawv screws rau cov ntoo los ntawm tib lub hlau yog ib tug tsis tshua xov suab (lub kaum sab xis ntawm ^txog 45 tus txheeb ze mus rau sab saum toj profile), ntsig txog, thiab cov tsawg heev tooj lem. Qhov no yog vim lub fact tias nws cov qauv yog tsis khoom ntoo thiab tuab li hlau.

Yuav ua li cas yog cov screws rau wood

Nyob rau hauv cov tsos, uas nyob rau hauv lub specifics ntawm manufacturing, lawv yog:

• kub (zheltopassirovannye);
• Dawb (galvanized);
• dub (phosphated).

Txawm li cas los ntawm cov xim, cov khoom pab rau zus tau tej cov screws, yog ib tug siab zog cov hlau. Nws undergoes ib tug tshwj xeeb kev kho mob uas tsub kom cov kuj mus ya raws. Tom qab ntawd, steel coated nrog zinc los yog ib tug nyias txheej los yog kho nrog ib tug tshwj xeeb tshuaj, muab nws ib tug daj xim, los yog phosphated los txhim kho slipping rau cov khoom nto thiab kom ntseeg tau ib theem siab ntawm adhesion nrog ib tug hau xov khoom. Nws yuav tsum tau muab sau tseg tias dub ntoo screws yog siv ntau npaum li cas feem ntau.

Structurally, lawv muaj xws li cov nram qab no Cheebtsam:

• Qws. Lub hauv paus ntawm lub ntsia hlau, uas yog threaded.
• Lub taub hau thiab. Nyob rau hauv tsos, muaj conical, carob, voj.
• Schlitz. Nyob ntawm seb lub cuab tam siv rau zawm, muaj tus ntoo khaub lig zoo li tus, ncaj thiab hex.
• Tswv yim. Nws yuav hliav los yog Sverlova daim ntawv.

Nyob ntawm seb lub hom phiaj rau attaching tej yam siv nyob rau hauv cov ntoo screws, qhov ntev lawv yuav ua tau heev txawv - los ntawm 11 mus rau 300 hli nyob rau hauv ntev. Qhov tseem nquag siv ntev screws 35, thiab 3.5 mm dav.

Nta ntawm qhov kev siv ntawm nws tus kheej-tapping screws

• Yuav kom compound yog txhim khu kev qha txaus, nws yog ib qho tseem ceeb los mus xaiv tus tseeb ntev ntawm lub ntsia hlau, uas yuav tsum tau ntau tshaj cov thickness ntawm cov lo qhov chaw nyob rau tsawg kawg nyob rau hauv ib nrab.
• Feem ntau ntawm cov screws siv luag tus yam tsis yuav tsum tau ua ntej drilling. Txawm li cas los, tej zaum peb yuav tau nrog hardwoods. Kom tsis txhob compromising lub sam xeeb ntawm lub qhov nyob rau hauv ib tug hlws ris nyob rau hauv cov ntaub ntawv no nws yog tsim nyog los tho ib lub qhov. Yog hais tias screws yog siv rau cov ntoo muaj ib lub cheeb ntawm ntau tshaj 4 mm, yuav tsum tau ua rau nws los mus tiv thaiv cracking ntawm tus ntoo. Lub qhov drilled nyob rau hauv ib tug ntev ntawm 2/3 ntawm cov ntsia hlau thiab xyaum txoj kab uas hla yuav tsum 1-1.5 hli thinner tshaj lub dav ntawm lub ntsia hlau. Vim nws yog heev yooj yim mus khaws ib tug tshwj xeeb laum rau wood ntawm yam kab uas hla, nws yog tej zaum yuav siv lub tib yam, tab sis cov hlau.
• Thaum uas siv cov rooj tog zaum screws (NTSIA HLAU) laum qhov yog yuav tsum tau. Yog li ntawd nws yog tsim nyog los siv ib tug tshwj xeeb laum muaj ib tug kuj tsis paub meej txoj kab uas hla raws nws ntev, xws li screws yog los ze zog mus rau lub taub hau thooj.
