Chifukwa chiyani akatswiri opanga zomangamanga akutembenukira ku Hollo-Bolts kuti alumikizane ndi zitsulo za Structural Hollow Sections-Chinese hollo bolts

Mawu Oyamba

Kulumikizana ndi zitsulo za Structural Hollow Sections (SHS) kuchokera kumbali imodzi kwatsutsa akatswiri kwa zaka zambiri. Komabe, pali mitundu yambiri ya zomangira ndi njira zolumikizirana ndi zida zomangika zomwe zikuchulukirachulukira, kupatula kuwotcherera. Nkhaniyi iwona ubwino ndi zovuta zina mwa njira zolumikizirana ndi SHS.theChina Hollo-Bolt, bawuti yowonjezera yomwe imafuna mwayi wofikira mbali imodzi yokha ya SHS.

Nthawi zambiri wopanga akasankha kugwiritsa ntchito SHS chifukwa cha kuthekera kwake kwa bi-axial kapena kukongola kwa mawonekedwe owoneka bwino ofananirako, funso lomwe limabuka ndi momwe mungalumikizire membala wina wamapangidwewo. Nthawi zambiri ndi mawonekedwe amapangidwe, kuwotcherera kapena kuwotcherera kwakhala njira yomwe amakonda chifukwa amatha kunyamula katundu wambiri. Koma pakakhala zoletsa pa kuwotcherera kapena pamene mainjiniya akufuna kupeŵa kukwera mtengo kwa ntchito zowotcherera zovomerezeka, kuyika, zolipiritsa zowotchera ndi kutenthetsa malo ozungulira, mainjiniya amayenera kutembenukira ku zomangira zamakina kuti ntchitoyo ithe.

Komabe, thandizo lili pafupi pomwe maupangiri apadziko lonse lapansi amasindikizidwa ndi mabungwe angapo odziwika bwino monga British Constructional Steelwork Association (BCSA), Steel Construction Institute (SCI), CIDECT, Southern African Institute of Steel Construction (SAISC), Australian Steel Institute (ASI) ndi American Institute of Steel Construction (AISC) omwe amathandizira pakupanga ma SHS. Mkati mwa maupangiri awa pali zomangira zamakina zosiyanasiyana, zoyenera kulumikizidwa kwa SHS, zikufotokozedwa ndipo zikuphatikiza:

Common Mechanical Fasteners

Kupyolera mu-Bolts amagwiritsidwa ntchito kawirikawiri, koma kusinthasintha kwachilengedwe kwa makoma a SHS nthawi zambiri kumalepheretsa kugwiritsa ntchito zomangira zokhazikika popanda ntchito yowonjezera, kotero kuti mfundozo zimapangidwira kuti azimeta ubweya wokhazikika. Zimapangitsanso kulumikizana ndi nkhope zotsutsana za membala wa SHS masikweya kapena amakona anayi kuti zikhale zovuta komanso zimatenga nthawi kuti zisonkhane pamalopo. Nthawi zambiri zowumitsa zimayenera kuwotcherera mkati mwa chubu kuti zithandizire, zomwe zimawononga ndalama zowonjezera.

Ma Studed Threaded Stud atha kugwiritsidwa ntchito pankhope za mamembala a SHS, ngakhale zida zolemetsa komanso zosagwira ntchito ziyenera kugwiritsidwa ntchito ngati mfuti yowotcherera ndi zida zogwirizana nazo. Izi zidzafunikanso kulingalira kofanana ndi kuwotcherera mamembala pamodzi poyamba. Iyi ndi njira yomwe ingatheke pasadakhale mumsonkhano wopanga zinthu musanatumizidwe kumalo. Nthawi zina, mabowo otsekeka kapena obowoledwa angakhale ofunikira kuti achotse kolala yomwe imatha kupanga pomwe cholumikizira chimakumana ndi nkhope ya SHS. Chomalizidwacho chidzatulutsa mawonekedwe a kulumikizana kwa bawuti koma kupangidwa mbali imodzi yokha ya SHS.

Blind Threaded Inserts amapezeka nthawi zambiri koma kugwiritsa ntchito kwawo kumakhala kochepa chifukwa cha kuchuluka kwa zinthu zomwe amatha kugwira, zomwe poyamba zidapangidwira zitsulo zachitsulo osati zigawo zachitsulo. Apanso, chida chokhazikitsa chikufunika chomwe chingafune kuyesetsa ngati buku lamanja lasankhidwa.

Ma Rivets Akhungu ngakhale kuti ndi oyenera kugwiritsidwa ntchito pomwe mwayi uli wocheperako, umakhala wopezeka m'madiameter ang'onoang'ono komanso akatundu opepuka. Sizinapangidwe kuti zilumikizidwe ndi zinthu zolemetsa, ndipo nthawi zambiri zimafunikira pneumatic / hydraulic supply pazida zapadera.

Chiyambi cha Maboti Okulitsa

Masiku ano timazindikira ma bolts ngati zomangira zamakina zomwe nthawi zambiri zimakhala ndi bawuti, mkono wokulitsa ndi nati wooneka ngati koni yomwe, pomwe bawuti yakhwimitsidwa, imayendetsedwa m'kati mwa manja kuti ipangitse chomangira ndikukulitsa chomangira. Njira iyi ya 'blind connection' itha kugwiritsidwanso ntchito polumikizana ndi intaneti ya mtundu wina wagawo. Mosiyana ndi zolumikizira wamba kapena zowotcherera, mabawuti okulitsa amatha kukhazikitsidwa mwachangu pongolowetsa cholumikizira mu dzenje lobowoledwa kale ndikumangitsa ndi wrench ya torque. Chifukwa cha kuyika kwachangu, ntchito pamalopo imachepetsedwa, motero mtengo ndi nthawi yomangayo zimachepa.

Kuyika kwa Hollo-Bolt

Kuyika Hollo-Bolts ndikosavuta ndipo kumangofunika zida zoyambira. Chitsulocho chimakumbidwa kale ndi mabowo okulirapo monga mwa zolemba za opanga, kuti agwirizane ndi manja ndi mtedza wooneka ngati cone, koma chisamaliro chiyenera kuchitidwa kuti mabowowo apezeke kuti alole kuti katunduyo atseguke mkati mwa SHS, kutanthauza kuti sangayikidwe pafupi kapena pafupi ndi mphepete.

Chitsulocho chikhoza kukonzedwa mokwanira mumsonkhano wopangira zinthu ndikusamutsidwa ku malo, kumene ubwino wa kukhazikitsa mwamsanga ukhoza kuyamikiridwa mokwanira. Ndikofunika kuzindikira kuti nkhope za mamembala kuti zigwirizane pamodzi ziyenera kukhudzana ndi Hollo-Bolt® isanakhazikitsidwe. Kuti amalize ntchitoyi, kontrakitala ayenera kugwira ntchitoChina Hollo-Boltkolala yokhala ndi sipanela kuteteza thupi kuti lisazungulira poikapo ndipo liyenera kumangitsa bawuti yapakati ku makokedwe ovomerezeka a wopanga pogwiritsa ntchito sikelo ya torque.
