Izikrufu zetruss zizikrufu ezinemilo ethile kunye nemisebenzi, ngokuqhelekileyo isetyenziselwa ukudibanisa iinxalenye ezahlukeneyo zesakhiwo se-truss. Zisetyenziswa ngokubanzi kubunjineli bomatshini, ubunjineli bokwakha, i-aerospace kunye namanye amasimi. Ubume kunye nobukhulu babo buhlala bubenza bafaneleke ngakumbi ukudibanisa i-truss

Kubalulekile ukukhetha izikrufu ezifanelekileyo xa ulungisa udonga lwe-particleboard. Izikrufu zokulungisa eziqhele ukusetyenziswa kwi-particleboard kwimarike yangoku zezi zilandelayo:

1. I-self tapping screws: ifanelekile ukulungisa iibhodi zeengqungquthela kwiindawo zekhonkrithi eziqinisiweyo kunye nentsimbi;

2. Isikrufu somthi: Isikrufu esisetyenziswa ngokubanzi esifanelekileyo ukulungisa iiplanga zamasuntswana kwizakhiwo zokhuni;

3. I-screws ye-socket: ifanelekile ukulungisa iibhodi zeengqungquthela kwiindawo eziphathekayo;

Kufuneka kuqatshelwe ukuba xa usebenzisa izikrini zokulungisa, izikrini ezifanelekileyo kufuneka zikhethwe ngokwemeko yangempela. Izikrini ezide kakhulu okanye ezifutshane kakhulu azifanelekanga, njengoko zinokuchaphazela umphumo wokulungisa ibhodi ye-particle board.

Izikrufu zentloko ye-pan zine-slot kunye ne-cross slot yokukhetha. Ukuba i-screwdriver yombane isetyenziselwa ukufakela, i-slot ye-cross ikhethwa ngokubanzi. I-Cross pan head self tapping screw sisikrufu sofakelo esiqhelekileyo esinentloko emise okwesiphambano esinokuqiniswa ngokulula ngescrewdriver. Into ephambili yolu hlobo lwe-screw yi-self-drilling intloko, oku kuthetha ukuba inokungena ngokuthe ngqo kwizinto eziphathekayo ngexesha lofakelo, iqinisekisa umphumo osisigxina.

Ihexagonal intloko self tapping screws luhlobo lwecandelo lomatshini. Izikrufu zokuzicofa ziqhele ukusetyenziselwa ukudibanisa iipleyiti zetsimbi ezibhityileyo (ezifana neepleyiti zentsimbi, iibhodi zeesarha, njl. njl.).

Izikrufu zentloko ezinehexagonal zibhekisa kwizikrufu zeplastiki ezinehexagonal zoomatshini - onke amazinyo (imethrikhi kunye neBritane) esebenza ngokugqwesileyo, i-non-magnetic, i-thermal insulation, ilula. Ezinye izikrufu zeplastiki ezenziwe ngezinto ezithile zinokumelana nobushushu obuphezulu, ukomelela okuphezulu, kunye nokumelana nomhlwa, kwaye zisetyenziswa kakhulu kwimimandla eyahlukeneyo yemizi-mveliso.

Igama le-drywall screw liguqulelwe ngokuthe ngqo ukusuka kwi-English Drywall Screw, kwaye eyona nto inkulu kwinkangeleko yimilo yentloko yophondo, eyahlulahlulwe yaba yilayini ephindwe kabini yesikrufu sezinyo esomileyo kunye nesikrufu somgca omnye orhabaxa. Umahluko omkhulu phakathi kwezi zibini kukuba owangaphambili unomtya ophindwe kabini, ofanelekileyo ukudibanisa iibhodi ze-gypsum kunye neentsimbi zetsimbi ezinobunzima obungadluli kwi-0.8mm, ngelixa eli lilo lifanelekileyo ukudibanisa iibhodi ze-gypsum ngeentsimbi zokhuni.

Uluhlu lwe-screw eludongeni olomileyo lungenye yeendidi ezibaluleke kakhulu kumgca wemveliso ye-fastener yonke. Le mveliso isetyenziselwa ukufakela iibhodi ezahlukeneyo zegypsum, iindonga ezilula zokwahlula, kunye nothotho lokumiswa kwesilingi.

I-countersunk self tapping screw luhlobo lwe-self tapping screw enezikhonkwane eziteyiweyo ezinokuthi zisetyenziswe ukukhusela izixhobo ezimbini ezahlukeneyo. Isici sayo esikhulu yinaliti ebukhali kunye nentloko ye-hemispherical countersunk. Iimpawu zayo zesakhiwo zinquma ukuba kulula ukungena kwimithi okanye ezinye izinto ezithambileyo, kwaye phantsi kwesenzo se-torque, ingena ngokuzenzekelayo kwizinto eziphathekayo kwaye iqiniswe ngokuqinileyo.

Izikrufu zetruss zinokwahlulwa ngokwesiseko zibe ziindidi ezimbini: ukusika izikrufu zetruss kunye nezikrufu zetruss zokubumba. Ukusika izikrufu zetruss kufezekiswa ngokusika imathiriyeli ekrwada kwiimilo ezisisigxina kwaye emva koko uzenze ngomatshini. Ngoko ke, imilo yabo yangaphandle ihlala rhoqo. Izikrufu zetruss ezibunjiweyo zenziwe ngokufudumeza intsimbi kunye nokusebenzisa umatshini wokubumba. Oku kuthetha ukuba imilo yezikrufu zetruss ezibunjiweyo zinokuba nzima ngakumbi.

I-Cross pan head self tapping screw sisikrufu sofakelo esiqhelekileyo esinentloko emise okwesiphambano esinokuqiniswa ngokulula ngescrewdriver. Into ephambili yolu hlobo lwe-screw yi-self-drilling intloko, oku kuthetha ukuba inokungena ngokuthe ngqo kwizinto eziphathekayo ngexesha lofakelo, iqinisekisa umphumo osisigxina.

Izikrufu zentloko ye-pan zine-slot kunye ne-cross slot yokukhetha. Ukuba i-screwdriver yombane isetyenziselwa ukufakela, i-slot ye-cross ikhethwa ngokubanzi.

Iibholiti zokwandiswa ziquka iibholiti ze-countersunk, iityhubhu zokwandisa, iiwasha ezisicaba, iiwasha zasentwasahlobo, kunye namandongomane angama-hexagonal.

Ukwandiswa kwe-screw yindlela esetyenziswa ngokuqhelekileyo yokulungisa iibholiti, ezifanelekileyo kwizinto ezahlukeneyo ezifana nekhonkrithi, i-aluminium alloy, insimbi, njl. I-screw yokwandisa yenziwe nge-screw kunye ne-wedge-shaped slope, egxininiswe emngxunyeni nge-diameter eguquguqukayo, eyenza ikhuseleke ngakumbi kuneebholiti eziqhelekileyo.

Ibholithi yokwandiswa kwenayiloni luhlobo lokumisa lwebholithi yokwandisa eyenziwe liqokobhe lenayiloni elingagugiyo kunye nebholithi enento yokutshixa. Kufanelekile ukufakwa kwizinto ezisisiseko eziqinileyo ezifana nekhonkrithi, iindonga zezitena, iindonga ze-convex, njl., kwaye zisetyenziselwa ukulungisa oomatshini, izixhobo, ifenitshala, njl.

Izikrufu zetruss zinokwahlulwa ngokwesiseko zibe ziindidi ezimbini: ukusika izikrufu zetruss kunye nezikrufu zetruss zokubumba. Ukusika izikrufu zetruss kufezekiswa ngokusika imathiriyeli ekrwada kwiimilo ezisisigxina kwaye emva koko uzenze ngomatshini. Ngoko ke, imilo yabo yangaphandle ihlala rhoqo. Izikrufu zetruss ezibunjiweyo zenziwe ngokufudumeza intsimbi kunye nokusebenzisa umatshini wokubumba. Oku kuthetha ukuba imilo yezikrufu zetruss ezibunjiweyo zinokuba nzima ngakumbi.

I-Cross pan head self tapping screw sisikrufu sofakelo esiqhelekileyo esinentloko emise okwesiphambano esinokuqiniswa ngokulula ngescrewdriver. Into ephambili yolu hlobo lwe-screw yi-self-drilling intloko, oku kuthetha ukuba inokungena ngokuthe ngqo kwizinto eziphathekayo ngexesha lofakelo, iqinisekisa umphumo osisigxina.

Izikrufu zentloko ye-pan zine-slot kunye ne-cross slot yokukhetha. Ukuba i-screwdriver yombane isetyenziselwa ukufakela, i-slot ye-cross ikhethwa ngokubanzi.

I-Countersunk self tapping screw luhlobo lwesikrufu esinomjelo ojiyileyo okhethekileyo. Intloko yayo yenzelwe ukuba sicaba kwaye inezakhiwo ezininzi zamazinyo kumphezulu, ukuyivumela ukuba izibhobhoze kumphezulu wezinto eziphathekayo kwaye yenze ukulungiswa okuqinileyo. I-Countersunk self tapping screws isetyenziswa ngokubanzi ukulungisa izinto ezahlukeneyo, njengentsimbi, ubhedu, i-aluminiyam, umthi, njalo njalo.

Umsila we-drill tail screw ukwimo yomsila we-drill okanye umsila otsolo, ngaphandle kwemfuneko yokuncedisa. Isikrufu somsila we-drill sinokugrunjwa ngokuthe ngqo, sicofe, kwaye sitshixelwe kwizinto ezimiselweyo kunye nezinto ezisisiseko, ukonga kakhulu ixesha lokwakha. Izikrufu zomsila ogrunjiweyo zizikrufu eziqhelekileyo, ezinokuqina okuphezulu kunye namandla okugcina. Emva kokudibanisa ixesha elide, abayi kukhulula, kwaye ukusetyenziswa kokugaya okukhuselekileyo kunye nokucofa kulula ukugqiba kumsebenzi omnye.

Injongo yokubhoboza izikrufu zomsila kukuba: luhlobo lwesikrufu somthi, esisetyenziselwa ukulungisa iithayile zetsimbi ezinombala kwizakhiwo zetsimbi, kwaye zingasetyenziselwa ukulungisa amacwecwe amancinci kwizakhiwo ezilula. Ayinakusetyenziselwa ukulungiswa kwesinyithi kwintsimbi.
