Ndezvipi zvakasiyana-siyana zvekubatanidza simbi?

Zvisungo zvinhu zvechiumbwa zvinoshandiswa kujoinha nhengo dzakasiyana dzechimiro chesimbi. Steel Structure muunganidzwa wenhengo dzakasiyana dzakadai se "Beams, Columns" ayo akabatana kune imwe, kazhinji panhengo inopera fasteners kuitira kuti iratidze imwechete inoumbwa unit.

Kubatanidza muzvivako zvesimbi

·Riveted Connections

Wakamboona mabhiriji, zvitima, boilers, ndege, kana zvimiro zvakakura zvinobatana nebhatani-sechimiro? Zvakanaka, bhatani iro rinonzi Rivet. Riveted joints imhando ye mechanical fastener iyo inoshandiswa kubatanidza zvidimbu zviviri kana kupfuura zvezvinhu pamwechete. Iwo anosanganisira akatevedzana ma rivets, ayo anopinzwa nemaburi mune izvo zvinhu uye zvobva zvaremara kana kuti "set" panzvimbo yekugadzira yakachengeteka yakabatana.

Rivet chitanda chedenderedzwa chinoshandiswa kubatanidza zviumbwa zviviri zvesimbi sezvo majoini akaumbwa kubva musimbi iyi yakapfava kana matanda emhangura akasimba kupfuura majoini akasungwa uye anopa kubatanidza nekukurumidza.

Mukutaura kwakapfava, riveted joint imhando yechigarire yekusungirira inoshandiswa kubatanidza mahwendefa esimbi kana zvikamu zvesimbi zvakakungurutswa pamwechete. Aya majoini anoshandiswa zvakanyanya muzvivakwa zvesimbi kana mabasa ezvimiro senge mabhiriji, matanda edenga, uye mumidziyo yekumanikidza senge matangi ekuchengetedza & boilers.

·Bolted Connections

The bolted joint is among the most common threaded joints. Ndidzo nzira dzekutanga dzekutakura mutoro muzvikamu zvemuchina. Zvinhu zvikuru zvejojo ​​yakasungwa itambo yakasungwa uye nati inodzivirira kusunungura bhaudhi.

Majoini akasungwa anoshandiswa zvakanyanya mukuvaka uye dhizaini yemuchina senzira yekubatanidza zvikamu pamwechete. Rudzi urwu rwejoints rine chisungiso chemurume chakarukwa, senge bhaudhi, neshinda yechikadzi inoenderana inochengetedza zvimwe zvikamu panzvimbo. Tension joints uye shear joints ndiwo marudzi maviri ekutanga emabolted joint designs. Nepo dzimwe nzira dzekujoinha, dzinosanganisira welding, riveting, adhesives, press fits, pini, nemakiyi, zvakajairika, majoini akasungwa anowanzo shandiswa kubatanidza zvinhu uye kugadzira zvimiro zvemakanika. Chaizvoizvo, bhaudhi rejoini musanganiswa wechisungiso uye nati, ine bhaudhi refu uye nati iri muenzaniso wakajairika.

Bolted Majoini anotsanangurwa semajoini anopatsanurika ayo anoshandiswa kubata muchina zvikamu pamwe chete nenzira yekusunga shinda, kureva bhaudhi uye nati. Sezvo majoini aya ari emhando dzisiri dzechigarire, nhengo dzinogona kupatsanurwa kuti dzigadziriswe, dzitariswe, uye dzitsiviwe pasina kukanganisa kukuvadza kune imwe neimwe zvikamu.

Bolted Joints akanyanya kukwirira kune zvisingaperi majoini senge welds uye rivets, izvo zvinokonzeresa kukuvadza kune zvikamu kana zvikamu zvaparadzaniswa. Zvikumbiro zvinosanganisira kubatanidzwa kwezvikamu zviviri zvinoda kupatsanurwa nguva nenguva.

Majoini akasungwa anonyanya kuumbwa nezvikamu zviviri. Iko kusanganiswa kwefastener uye nut. Inoumbwa nebhaudhi refu ine nzungu pairi. Bhaudhi rinopinzwa mugomba rakafanoboorwa muzvikamu, uye nati yobva yasimbiswa patambo yekubatanidza yebhaudhi. A bolted connection ishoko rekubatanidza rebhaudhi nenati.

Shinda dzinogadzirwa nekugadzira helical groove kunze kwedenderedzwa shaft kana gomba. Kune nzvimbo dzakasiyana-siyana dzekushanda uye kushandiswa kwemajoini akasungwa. Pane zvakatarwa zviyero zvemhando dzese idzi dzakasiyana. Izvi zvinovimbisa kuti majoini akasungwa anochinjika kune akasiyana mabhureki.

·Welded Connections

MAMATYPES OF WELDED CONNECTIONS

Mhando dzakakosha dzemajoini akasungwa anogona kuverengerwa zvichienderana nemhando dze welds, chinzvimbo che welds uye mhando yejoini.

1. Kubva pamhando ye weld

Zvichienderana nemhando ye weld, welds inogona kuiswa mu fillet weld, groove weld (kana butt weld), plug weld, slot weld, spot weld etc. Mhando dzakasiyana dze welds dzinoratidzwa muFigure 15.

1.1. Groove welds (butt welds)

Groove welds (butt welds) uye fillet welds zvinopiwa apo nhengo dzinofanira kubatanidzwa dzakarongwa. Groove welds inodhura sezvo ichida kugadzirira. Groove welds inogona kushandiswa zvakachengeteka munhengo dzakanyanya kushushikana. Square butt welds anopiwa kusvika kune plate ukobvu hwe8mm chete. Mhando dzakasiyana-siyana dzebutt welds dzinoratidzwa muMufananidzo 16.

1.2. Fillet welds

Fillet welds inopiwa apo nhengo mbiri dzinofanira kubatanidzwa dziri mundege dzakasiyana. Sezvo mamiriro ezvinhu aya achiitika kakawanda, fillet welds yakawanda kupfuura butt welds. Fillet welds iri nyore kugadzira sezvo inoda kushoma kwepamusoro kugadzirira. Zvakadaro, iwo haana kusimba senge groove welds uye anokonzera kusangana kwekushushikana. Fillet welds inosarudzwa munhengo dzakasimba zvishoma uko kuoma kwete kusimba kunotonga dhizaini. Mhando dzakasiyana dzefillet welds dzinoratidzwa muMufananidzo 17.

1.3. Slot uye plug welds

Slot uye plug welds inoshandiswa kuwedzera fillet welds uko hurefu hunodiwa hwefillet weld haugone kuwanikwa.

2. Kubva pachinzvimbo che weld

Zvichienderana nechinzvimbo che weld, welds inogona kuiswa mu flat weld, yakatwasuka weld, vertical weld, pamusoro zvakanaka etc.

Kubva pamhando yemajoini

Zvichienderana nerudzi rwemajoini, ma welds anogona kukamurwa kuita butt welded joints, lap welded joints, tee welded joints uye makona welded joints.
