Imilinganiso yalo isibiyeli metal - Standard

Metal kwikona - imveliso esisetyenziswa ngokubanzi kushishino, kwizakhiwo nezakhiwo, kwakunye nakwezinye iindawo ezoqoqosho. Uyilo ekhethekileyo olu hlobo nomnombo abe ukuqina eliphezulu kwaye zingasetyenziswa indibano scaffolds kunye nomda enkulu ukhuseleko. It is a kwikona imveliso sentsimbi elide, e-cross-kwicandelo efana ileta "G". ngokulinganayo kunye ukungalingani: Kukho ezimbini kuphela ntlobo zalo omkhulu. Kwimeko yokuqala, ububanzi iimveliso 'kwithala' iyafana kwi yesibini - eyahlukileyo. Engqonge isibiyeli yesinyithi, ubunzima kunye nohlobo lwezinto ezisetyenziselwa imveliso silawula GOST.

ngezigaba

angles Equal kunye nokungalingani kungaba:

• goryachekatnymi (bokwenziwa ngokwemigangatho emiselwe GOST 8510-86 kunye GOST 8509-93);

• egosogoso (GOST 19771-93 kunye GOST 19772-93).

Uhlobo lokuqala uye amandla aphezulu. Le ndawo ngokuqhelekileyo asetyenziswe ekwakheni izakhiwo zentsimbi baboniswa layisha phezulu. iikona egosogoso zezona kakhulu zithandwa. Zisetyenziswa kuyo yonke indawo. Lo msebenzi wenziwa ngokugoba njengemicwana yentsimbi kwi izixhobo ezikhethekileyo bale.

Kwakhona, ezi mveliso yesinyithi zahlulwa kwi:

• eqhelekileyo;

• ukuchana eliphezulu.

Uhlobo lokuqala ephawulwe ileta "B", okwesibini - "A".

Ubude angela metal

Ngokutsho parameters wemveliso zihlelwa kwi kulinganiswa ne unmeasured. Kukho kwakhona kwikona ubude ezininzi kwaye lunomnyino. iimveliso mbini kunokuba ubude 6, 7, 9, 10, 11 okanye 12 m. indleko yabo ixhomekeke ubunzima (t. E. Umxhasi ayihlawuli ukuba iyunithi imveliso kunye ubunzima lilonke uthenga noma, kwiimeko kakhulu, kuba yardage). indawo Unmeasured unokuba nayiphi na ubude. Kulo mzekelo, eli nani yahluka ukusuka-4 ukuya m-12. Kwiimeko ezininzi, olu hlobo izinto zokwakha azikho ixesha elide kakhulu, ukususela lokucheba rhoqo nje amanqaku mbini.

Ngamanye amaxesha, ekwenziweni iintlobo ezahlukeneyo lezakhelo, izakhiwo umthwalo-ngokuzala, njalo njalo. D. Akufunayo ukuba ubungakanani kwizibiyeli yesinyithi akumgangatho. Kulo mzekelo, umthengi ithuba ukuyalela imveliso elide ngaphezu m-12.

ubude imposiso

Phakathi kwezinye izinto, ulawula kunye GOST nokumelana kwikona kule parameter. akufuneki ukuba zifunwaEzokugqibela ngaphezu:

• 30 mm ukuba ubude-4 m lembombo;

• 40 mm iimveliso 6 m;

• 70 mm yobude engile-6 ukuya ku-12 m.

Phezu isicelo, i parameters lisenokuthi litshintshwe bejonge ukuchana enkulu (40 mm iimveliso 4-7 m kunye ne-5 mm ngemitha nganye ubude ngaphezu kwe-7 m). GOSTS nokulawula nje kuphela ubungakanani yembombo metal ngokulinganayo olungalinganiyo, ubunzima lwabo kunye nokumelana, kodwa ke iqondo amagophe. Ngapha koko, iimveliso ezikumgangatho ophezulu kufuneka ube ngqo. Elona xabiso liphezulu ugobile lembombo GOST mayingagqithi 0.4% ye ubude. Xa isicelo lweshishini loMthengi, wenza imveliso iimveliso ngesinyithi enziwa kunye ugobile angekho ngaphezulu kwe-0.2% ye ubude. Ukucofa amagumbi kwicala ngeenxa esqwini abavumelekanga.

Ububanzi ezishelfini kunye ubunzima

Yintoni, enyanisweni, anokuba ubungakanani metal engile? GOST kakhulu silawula umlinganiselo ezishelifini Ububanzi ezi mveliso, ubukhulu kunye nobunzima babo. Icandelo lokuqala isusela ukusuka mm-20 ukuya 200. Ububanzi imveliso unako ukufikelela-16 mm. Yintoni kanye ukuba kuba umlinganiselo kobubanzi ezishelfini ubunzima wemitha enye imveliso, funda le theyibhile ingezantsi.

Ngentla thaca amaxabiso ratio ukwenzela iimveliso aku-. Njengoko ubona, xa ububanzi efanayo Ebubanzini ezishelifini zinokohluka. Ngako oko, utshintsho kunye nobunzima. Corner metal dimensions engalinganiyo, hayi kanye mandithi, ububanzi "iishelfu" yayo, angayitshintsha ngaphakathi 20-200 mm. Ixabiso le parameter ubunzima kweempahla kule meko kulawulwa GOST kwaye eboniswe kwITHEBHULE ezizodwa.

grade steel

Iyahlala metal engile kuxhomekeke nje kuphela indlela wokwenziwa, nezinyuko kunye nobubanzi ezishelfini. Unefuthe kule parameter uze onjani izinto yasetyenziselwa eyimveliso imveliso. Yenza indawo ezi ntlobo zilandelayo ngentsimbi:

• Carbon ubunjani obuqhelekileyo;

• ingxubevange ephantsi amandla aphezulu.

Kwimeko yokuqala amanqaku yesinyithi, iimpawu kwentsebenzo kulawulwa GOST 380-88. yodidi Quality ingxubevange esisetyenziselwa nokuveliswa kwizibiyeli, uchaza GOST 19281-89.

Eyona ethandwayo ubungakanani metal engile

Iimveliso uthandwayo olu hlobo ayimveliso baphikele ukusuka ayoni metal kwibakala le 'B'. Olu khetho zitshiphu ngaphezu ekoneni insimbi "A" iklasi. Ukongeza, ezi iikona zehlile e kwaukuzibandeza ezaneleyo zokhuseleko ukuya kwenye angaqokelela zokwakha ixesha elide kwaye zithembeke.

Zeziphi ubukhulu uthandwayo lembombo metal? 40 x 40 mm, 50 x 50, 70 x 70 no 100 x 100 mm - ububanzi ezishelifini ezinjalo ethandwa kakhulu. iimveliso ATHUNYIWEYO Okokuqala, umzekelo, zingasetyenziswa ezivelisa izikhuselo zeseyile, pergolas, izitulo, iitafile, yaye ngoko esitratweni. D. Kuba sezakhiwo ezibalulekileyo kakhulu indawo enjalo kwaukuzibandeza olwaneleyo ukhuseleko.

Amanqaku 50 x 50 mm zingasetyenziswa kwindibano iingcingo, amasango, screens, oojingi ezincinane umntwana kunye t. D. Sebenzisa la manqaku obunjineli boomatshini kwaye uzidibanisa w / iinqwelo. Imilinganiso yalo isibiyeli metal 50h50h5 mm okanye 50h50h6 mm zikuvumela ukuba ukuqokelela zonke iintlobo amathambo abafumana umthwalo encinane. Kwezinye iimeko, ke angásetyenziswa kukho ixesha elide -50 x 50 x 3 okanye 50 x 50 x 4 mm. Le ndawo ubunzima ngakumbi kwaye ngoko neendleko ngaphantsi.

isibiyeli steel kwalenza

rhoqo yenkcenkce uhlobo ezisetyenziselwa indibano izakhiwo zesinyithi, ngexesha nokusebenza kakubi ibingenakunyakama. Ekubeni steel eqhelekileyo kuxhomekeke umhlwa, kule meko wayedla uhlobo olulodwa angle metal - kwalenza. Ingaba olu khetho luyabiza, kodwa kwiimeko ezininzi ezinzima singahlala amashumi. Ubungakanani angela iintlobo metal (ububanzi kunye Ebubanzini ezishelifini) ayafana nje ukuba le eqhelekileyo.

imveliso eyenziweyo of becala ezi zilwanyana carbon ngentsimbi. Galvanizing njalo ingaveliselwa ngeendlela ezininzi. Ekoneni emanzini elula baphele wafumana imveliso ngomaleko ubukhulu ibakhusela microns 150. Maxa wambi galvanizing oluqhutywa ngendlela ujikeleza, atywinwe isikhongozelo kwiqondo lobushushu eliphezulu. Kulo mzekelo, izinc lingena singene umaleko ongaphezulu ngentsimbi, nangona Ebubanzini maleko yaso nayo ulingana microns 150, igcinwe ngcono kakhulu. Kwakhona ehlanganiswa yile intsimbi yesinyithi ukuze wokutshiza. Ngoko ke kunokwenzeka ukuba ukusebenzisa umaleko ziyatyeba kakhulu zinc - up to ngemilimitha eziliqela.
