Beam kabini-tee: Imilinganiselo. I-beam ngomthi

Ngemiqadi asetyenziswe ekwakheni xa ukwakha uphahla, iisilingi, imigangatho , njalo njalo. D. Kukho iintlobo-ntlobo. Iintlobo kunazo ndim umqadi - uyilo okhethekileyo, e-cross-Section uphinda unobumba "H". Le izinto zokwakha ezenziwe itoti yesinyithi okanye nemithi.

Steel I-msebe

Ngenxa kokukhululwa kwale iintlobo inokusetyenziswa carbon liqengqiwe kwaye ephantsi ingxubevange ngentsimbi. Faka I-Imiqadi kwiindawo ezininzi zokwakha yoluntu kunye nezoshishino. Kudla esetyenziswa le nto, ukuba kuyimfuneko ukunika isakhiwo isakhelo okanye nayiphi na inxalenye yayo anda amandla nokoma. Kukho I-ngemiqadi welding iveliswayo ehlelayo eshushu. Owokugqibela ke athandwa kakhulu.

amandla .GOKO kule nto kukho enye inzuzo. I- yemiqadi yokuhlanganisa abamelana kakhulu yokuguquguquka lobushushu. Ngoko ke, kumaxesha amaninzi aba nalo asetyenziswe ekwakheni amagumbi okulala.

scope

Ngokusisiseko, Beam kabini-tee, ubukhulu apho zisenokwahluka, esetyenziswa ekwakhiweni imigangatho ekwakhiweni kwezakhiwo mveliso kunye yoluntu. Kananjalo uhlobo irenti isoloko isetyenziswa xa ukwakha iibrorho nangenxa Ukuqinisa emigodini. ngokubanzi kakhulu wasebenzisa eli Umama efumaneka kulwakhiwo emotweni kunye neemoto.

Forms I-echweliweyo

Olu hlobo ihlelwa liqengqiwe hayi kuphela indlela wokwenziwa, kodwa phezu nkcukacha kokwakhiwa. Le umqadi unokuba kabini-tee njengoko iishelfu parallel, ilahlwe kwi-engile. Kwimeko yokugqibela, irenti yahlulahlulwe:

• ekhethekileyo,
• eqhelekileyo (kunye iishelfu ithambeka ukusuka kwisi-6 ukuya ku-12%).

Special I-beam (GOST 19425-74), ke, zahlulwa kwi:

• kujongwe ukubethelela shaft (ziyaphawulwa ngokuzibhala ileta "C");
• ezisetyenziswayo xa kwenziwa imveliso yomendo bobuxoki ( "M").

Imiqadi kunye flanges parallel (GOST 26020-83) zahlulwe:

• eqhelekileyo (ephawulwe "B"),
• elive- (W),
• Tower (K).

Kwakhona metal I-echweliweyo zisenokwahluka ngokutsho Ebubanzini ezishelifini kunye neendonga.

Beam kabini-tee: Imilinganiselo

Ukuphakama kwalo mbono cross-somhlathi of liqengqiwe Unganawo ezahlukeneyo. Eli nani siyahlengahlengiswa yeendwendwe aze agqibe kunokwenzeka yayo inombolo umqadi. Ngoko ke, kukho ukuphakama 140 mm njengoko izinto eziza kumakishwa 14C ngo-360 mm - 36M, etc ...

Ubukhulu ezithile elements ukwakhiwa olu hlobo nomnombo limiselwa iitafile ezizodwa. Kwezi, kunokwenzeka ukuba ukwazi ubunzima I-ug.

legend:

• b - Ububanzi ezishelfini,
• t - balo babulingana nesandla avareji,
• S - udonga balo babulingana nesandla,
• h - ukuphakama I-umqadi ube mnye,
• R - radius lwangaphakathi amagophe ezinyongeni,
• iishelfu radius R-.

Neyophahla imisebe yeplanga

Olu hlobo zokwakha, ezifana intsimbi, lubonakala ngamandla aphezulu kunye nokusebenza kakhulu. Umakad H-beam ngomthi enziwa ucwecwe okanye OSB, ezishelifini - ukusuka imithi uncwelwe. Kukho kwakhona uhlobo ngamaplanga. Kulo mzekelo, ubambo izenzo buKristu laminate. Njo I-echweliweyo mancinane basengozini ezibolayo. Ukongeza, ukuba umlilo kakhulu ukumelana.

Xhume omnye komnye I-echweliweyo eyenziwe ngomthi kunye kwizibiyeli ezikhethekileyo. Le yokugqibela luqulathe iipleyiti zesinyithi enxuseneyo kunye isixhobo lokutshixa. Izihlanganisi kunokuba abe nobukhulu obahlukeneyo. Ukuba kuyimfuneko, kuya kuba lula ukuba liyahambisana khetho, Lifanele ukuphakama imiqadi eziphathekayo.

Ububanzi bokusebenzisa

Used kabini-tee umqadi ngomthi ubukhulu becala ukwakhiwa kwezakhiwo benqwanqwa-ikhaka. Kwakhona, le nto badla ibe inkxaso Iizilebhu ngezitena, ibhloko kunye namakhaya aqinileyo eziphathekayo. Le imigangatho ebekwe yemiqadi yokuhlanganisa ka luphawulwa ngqongqo zininzi iintlobo, musani uvuleka bangaze begoba.

Ngenxa ukwakhiwa uphahla kwezakhiwo ezinkulu ezenziwe I-ngemiqadi kubekwa zingenziwa ihashe. Le izinto ezintsha kunokwenza ngempumelelo indawo ngokwamandulo kusetyenziswa kule njongo, imiqadi zomthi, ngumngundo zesinyithi, iibhulorho. Ngokuqhelekileyo, umenzi enika siqinisekiso kwi I-ezinemiqadi echweliweyo yemisedare phezu yonke imigca isakhiwo nkonzo.

Benefits Product

Izinto eziluncedo ze kabini-tee umqadi ngamaplanga ihleliwe. Le nto zizakubalulwa neempawu ezifana:

• Strength. I-imiqadi ingafakwa imingxunyana elide kakhulu.
• uzinzo ntathu. Ezi imiqadi musa ukugoba kwaye phantsi shrinkage kunye deformation.
• Lula ufakelo. Handle le zokwakha zixhobo ukuchwela oluqhelekileyo.
• Nsimbi. Ukusetyenziswa umqadi kunye ezishelifini ababini ibe ukwakhiwa floor, imigangatho, amadonga, uphahla kunye like. D.
• Ndandifeketha na. Weight I-msebe eyenziwe ngomthi yi 3-4 kuphela kg. Ukukhulisa into enjalo, umzekelo, uphahla akafuni ufuna izinto zokusebenza ezithile. Yenza oko aba- ntu ababini kuphela.
• iindleko Low.

izinto Ubukhulu

Kunye nokwakhiwa kwezakhiwo ungasetyenziswa ezahlukeneyo umqadi kabini-tee. ubungakanani bayo, ngokufuthi esetyenziselwa ukwakha, zezi:

• ubude - 241, 302, 356, 406 mm,
• ububanzi kwi - 64 mm,
• esisangqa ubukhulu - 38 mm.

Ekubeni le nto idla ngokusetyenziswa ibandla nakwiisilingi kwi amathuba abanzi kakhulu, ngamanye amaxesha kuyimfuneko ukwakha up. Isniphu uvunyelwe. Xa amalungu imiqadi ezimbini lock ngexesha elifanayo zapilivaem. entengo olongezelelweyo owenzekayo iibholiti.

Ngokubanzi, izinto zokwakha ixesha elide kakhulu yaye kwizinga eliphezulu Imfono - ngomthi I-echweliweyo. GOST, njengoko kunjalo lweentlobo yesinyithi, ulawula umlinganiselo ubude nobukhulu iinxenye zale hlobo isekela. Jonga ukuba babe ezitafileni ezizodwa.

Njani I-umqadi ekhaya

Ukuba oyifunayo, kwakhiwa onjalo kuveliswa kwaye ekhaya. Oku kuya kufuna icandelo ezimbini bar ubuncinane 35h25 mm. Jumper ezenziwe ngamaplanga okanye OSB. Kananjalo kuya kufuneka ukuba i zombane okanye chainsaw. Umsebenzi oluqhutywa ngolu hlobo lulandelayo:

• Okokuqala, imivalo kunye lonke ubude yekati groove ubunzulu wabo-10% yabo ukuphakama ulungqu.
• Bona ke ngoko, bahlabeka ubude oyifunayo, uze sanded.
• Emva koko, lo ezantsi ngamnye umsele isicelo iglu.
• Running imiqadi ambaxa pairwise usebenzisa ngamaplanga okanye OSB.

Kwinqanaba lokugqibela umqadi ogqityiweyo ukuba sibekwe ngaphantsi eendaba. Ukwenza kube lula kwakhona ngokuzimeleyo. Ukulungiselela le njongo, nemivalo ijelo. Bona ezibekwe ngecala ezishelifini kwaye ukutsala kunye usebenzisa zokuzenzela okanye namabhanti.

izinto zokwakha bayibhalayo kutshiphu kakhulu kuthengwe Beam kabini-tee. Ixabiso lo wokugqibela uyatshintshatshintsha ngeenxa 200-250 engange. Eqokelelwe wena uya kuba kwamnceda izihlandlo 1.5-3 enganeno.

Aluminium I-echweliweyo

Ukwakha olu hlobo zokufunda kwakhona luye lwaphucuka amandla. Kabini-tee umqadi yenziwa aluminium ingxubevange ngokuqhelekileyo AD31. Olu hlobo amaninzi asetyenziswe ukwakhiwa kwezindlu. Kwakhona imiqadi zenziwa aluminium ingxubevange 1915 Olu hlobo iye amandla aphezulu. Aluminium neyophahla namandla ngokukhanya ngaphezu imithi ngentsimbi.

ezahlukeneyo izinto

Kukho aluminium I-, iyimithi;

• lukhuni,
• annealed,
• abaneminyaka.

Le nkcazelo ngeso lenyama ukuba ipeyintwe, steel, umgubo, electrophoretic, isakhiwo umaleko-mbini. Ngokutsho imiqathango yokusetyenziswa aluminiyam I-imiqadi, kunye nesinyithi, lungohlulwa lube elive-, kwikholam kunye eqhelekileyo. Iileyibheli kulo mzekelo isebenzisa efanayo.

Ubukhulu

Aluminium kabini-tee umqadi ubungakanani nazo zinokuba nomahluko. Iilinganiselo kulo mzekelo zimiselwa GOST. Kakuhle wenza nokufaka. Ukuphakama umqadi aluminiyam ziyahluka ukusuka cm-10 ukuya 100 kwimeko yokuqala ngokwe GOST webutho, kuya kuba ububanzi 55 mm ubukhulu -. 4.5 mm. Ukumisela umlinganiselo parameters kwimeko nganye tafile.
