Hauv kev tsim kho niaj hnub no, siv ntau yam khoom siv kho vajtse ntau heev. Nyob rau tib lub sijhawm, nws yog qhov tsis xav ua yam tsis muaj qhov ntev tshaj plaws tshwj xeeb fastener, uas yog hu ua "foundation bolt". Nws kuj muaj lwm lub npe nrov - "hairpin"

Raws li nws tsim, lub hauv paus ntsia liaj qhov rooj yog ib puag ncig ntawm qhov ntev, ua los ntawm cov hlau. Ntawm nws qhov kawg muaj ib txoj xov uas tsim los rau ib qho ntawm qhov ntau thiab tsawg ntawm cov txiv ntoo. Rau kev tsim cov khoom siv kho vajtse no, ntau hom hlau siv. Lawv tuaj yeem txheeb xyuas tau yooj yim los ntawm cov cim uas siv rau lub fastener no. Cov kev txwv ntawm lub hauv paus bolts yog tswj los ntawm GOST 24379.1-80. Nws qhia txog hom, ntev, version, txoj kab uas hla thiab suab ntawm cov xov, qib steel. Kuj tseem muaj cov lus piav qhia ntxaws thiab kos duab ntawm ntau yam ntawm cov fasteners.

Nyob ntawm qhov xwm txheej ntawm qhov thauj khoom thiab qhov loj, hom ntawm lub hauv paus, kev txhawb nqa, cov bolts txawv raws li cov qauv sib txawv:

  • raws li kev khiav haujlwm: tsim (lub zog) thiab tsim qauv (hloov me me);
  • bydesigns;
  • by installation method: embedded thiab lag ntseg;
  • raws li txoj kev kho hauv lub hauv paus - embedded hauv lub hauv paus thaum lub sij hawm tsim khoom, ntawm cov kua nplaum, ntawm cov cement-xuab zeb sib tov, wedged.

Lub hauv paus ntsia liaj qhov rooj tuaj yeem siv ntau txoj hauv kev. Feem ntau nws yog siv los tsim cov pob zeb ua kom muaj zog ntawm txoj kev teeb tsa. Nrog kev pab los ntawm lub hauv paus studs, kev sib txuas muaj zog nrog cov hauv paus ruaj khov yog tsim. Yog li kev xyaum siv cov fastener no rau kev teeb tsa cov cuab yeej loj (tswj cov cuab yeej, conveyors) yog dav. Qhov no yog vim qhov ntev heev ntawm cov studs thiab threaded kev twb kev txuas. Cov yam ntxwv ntawm lub hauv paus bolts ua rau nws muaj peev xwm los tsim ib qho fastening uas zoo kawg nkaus resists me me dynamic loads nyob rau hauv daim ntawv ntawm kev co los ntawm hluav taws xob motors.

Nyob hauv paus studs

Raws li GOST, tag nrho cov fasteners no tau muab faib ua 6 hom. Lub hauv paus bolts tuaj nyob rau hauv qhov ntev sib txawv thiab muaj cov xov sib txawv ntawm lawv qhov kawg. Nyob ntawm lawv tus qauv tsim, lawv tuaj yeem muaj qhov sib txawv txuas rau lub hauv paus. Hauv qab no yog cov feem ntau hom ntawm hom mounts:

  • Lub ntsia liaj qhov rooj yog nkhaus. Nws tuaj yeem yog ob hom: tus pas nrig ncaj nraim rau qhov khoov lossis khoov ntawm lub kaum sab xis (15-30 degrees). Fasteners ntawm hom thib ob tuaj yeem tiv taus qhov hnyav.
  • Khob bolt. Nws tuaj nyob rau hauv ob subspecies: nrog txiv ntseej raws li GOST 5915-70 thiab GOST 10605-72. Cov bolts no tuaj yeem ua taunce nyob rau hauv ntev. Qhov kev txuas ntxiv yog nqa tawm siv lub tes tsho hlau ntsia hlau rau hauv ib feem ntawm lub fastener tsau ntawm lub hauv paus.
  • Bolt nrog thauj tog rau nkoj phaj. Muaj peb hom. Thawj ob muaj qhov sib txawv ntawm cov txiv ntseej, thaum lub thib peb muaj cov phaj tshwj xeeb zoo li cov thauj tog rau nkoj.
  • Txhim kho qhov ntsia hlau. Lub fastener no yog ntawm peb hom. Tag nrho cov ntawm lawv txawv ntawm ib leeg los ntawm thauj tog rau nkoj fittings thiab ib tug sab nraud txiv ntseej. Tshem tau fasteners yuav luag txhua qhov ntev. Cov yeeb yam no piav qhia vim li cas lub hauv paus bolts thiaj li nrov. GOST 24379.1-80 muab rau 3 hom kev ua tiav ntawm cov fasteners. Lawv txawv nyob ntawm txoj kab uas hla ntawm cov xov. Foundation thauj tog rau nkoj bolts feem ntau yog siv rau hauv kev ruaj ntseg cov cuab yeej. Lawv ua kom yooj yim thiab yooj yim rau mount lossis dismantle ib lub tshuab.
  • Ncaj bolt. Hom fastener no suav hais tias yog classic. Nws cov ntug qis tuaj yeem welded yooj yim rau kev txhim kho ntawm cov pob zeb ua kom muaj zog ua ntej nws tau nchuav nrog pob zeb.
  • A bolt nrog tapered kawg. Nws txawv ntawm lwm hom nyob rau hauv cov duab ntawm qhov kawg ntawm lub hardware, uas yog txuas nrog lub hauv paus. Nws muaj ib tug expanding conical duab. Ua tsaug rau nws, lub hauv paus ntsia liaj qhov rooj yog ruaj khov thiab nws tsuas yog tsis yooj yim sua kom rub nws tawm ntawm lub pob zeb. Muaj ntau ntau yam ntawm hom fastener no.
