Kudalirika mothandiza nyumba adzapereka I-mtengo

Ine_ zitsulo matabwa ntchito ndi pafupifupi masiku ano kumanga malo, onse mafakitale ndi boma. Ndi yokoka wotsika yeniyeni, iwo ndi mkulu katundu mphamvu kuchimwa kuti angathandize kugawa katundu pa nyumba ya akuthandiza. Izi zopangidwa pakubwezeretsa zitsulo mankhwala (mankhwala zitsulo, wosachedwa adagulung'undisa awiri poponya mtanda) kapena njira kuwotcherera. The yachigawo ndi H woboola pakati mamangidwe a linga ndi flanges awiri perpendicular kwa izo. The maalumali mwina ndi kukondera mkati kuti amveke zina. mankhwala amenewa ali oyenera zolimba ndi mikondo amveke (mndandanda C ndi masinthidwe amtundu wa 16%) ndi inaimitsidwa ogwiritsa njira (mndandanda wa M ndi otsetsereka a 12%).

Adagulung'undisa awiri poponya mtengo komanso kutchedwa I-mtengo. Ntchito yaikulu ya mankhwala amenewa zitsulo - nyumba apansi, zomangamanga mlatho, njira inaimitsidwa, zipilala ndi mizati. Malinga ndi cholinga cha nyumba inamangidwa, steelI I-mtanda akhoza kusintha kwa workloads osiyana. Amapanga, I-Zigawo ndi osiyana khoma makulidwe a maalumali, ndi maalumali unali mbali (nkhope zawo mumtima mwina kufanana kapena otsetsereka). Ubwino ali ndi kusankha njira kupanga, cholinga ndi magawo luso.

Zitsulo mtengo awiri poponya angathe kukhala mogwirizana ndi miyezo ya boma (GOST 8239 - 89, Standard 19425 - 74, GOST 26020 - 83 ndi ena), komanso mogwirizana ndi specifications a Mlengi. Mu nkhani ya chuma anagubuduza ndi mpweya zitsulo structural wamba khalidwe. nyumba imeneyi zitsulo monga iwiri poponya mtengo anapangidwa kuchokera welded zitsulo structural otsika-aloyi kwa nyumba welded.

Angapo osiyana mitundu ya I-mitanda ndi nkhope kufanana maalumali: yachibadwa (B), ndime (K), wide- (W), Normal (SB), ndi mndandanda zina (L ndi LH). Anapanga awiri poponya mtengo pa mfundo malinga cholinga, ali ndi kutalika kwa 4 ndi 12 mamita (mogwirizana ndi makasitomala - 24 m). Kodi kukhala mkulu (A) kapena zachilendo (B) anagubuduza molondola.

Welded zitsulo I-matabwa anapangidwa ndi pepala zitsulo mu magawo angapo. Choyamba anapanga preform chofunika kukula ndi slicing iwo ku zitsulo, ndiye milled m'mphepete. Kukolola Mzere Crane ndi kunditumiza ku pazimalamba zozungulira, crimped ndi scald unsembe basi. Komanso, mankhwala wopindidwa mu msasa wapadera kuchotsa vuto zotheka ndi kukonzedwa ndi kabotolo mmela pakuti decontamination. Khalidwe la welded I-mtanda ayenera akwaniritsa zofunikira za GOST 23118-99 ndi GOST 26020-83 (kapena magawo ake zafotokozedwa pasadakhale ndi makasitomala).

I-matabwa athe 30% kuti magawowa katundu zobala nyumba poyerekeza ndi miyendo otentha. mtima kuyambirira mitanda zamitundu kwambiri kuchepetsa kuchuluka kwa zinyalala. The kuipa monga ine-matabwa osatetezedwa dzimbiri ngati palibe ❖ kuyanika zoteteza, ndipo kufunika kwa zida apadera, popanda zomwe iwo sangathe wokwera.
