Lub tsev ua los ntawm cov kab hluav taws xob lossis cov cav ntoo yuav sov thiab ruaj khov yog tias tsis ua txhaum kev tsim kho. Lawv tsim tau yooj yim dua thiab nrawm dua li cov tsev pob zeb. Kev tsim kho lub tsev cav yuav tsum tau them nqi tsawg, tsis tas yuav nyiam cov khoom siv hnyav, txhua yam khoom siv thiab cov cuab yeej muaj thiab pheej yig. Tab sis txhua lub tsev ntoo tau dhau los ua cov txheej txheem txaus ntshai - shrinkage, uas tuaj yeem cuam tshuam rau nws lub zog thiab cov ntaub ntawv zoo nkauj. Thiab txhawm rau kom tsis txhob muaj qhov tshwm sim tsis zoo, lossis tsawg kawg txo lawv, nws raug nquahu kom siv lub shrinkage compensator thaum lub sij hawm tsim kho lub cav.
Tshuaj ntawm lub tsev ntoo
Lub tsev cav yuav txo qis hauv 3-5 xyoos tom qab nws tsim. Nws tsis tuaj yeem tiv thaiv cov txheej txheem no. Qhov ua rau shrinkage yog noo noo nyob rau hauv lub cav los yog ntoo. Rau kev tsim kho, ntoo yuav tsum tau siv, cov dej noo ntawm qhov tsawg dua 20%. Tab sis tsis yog txhua tus, vim lawv cov nyiaj txiag lossis lwm yam peev xwm, tuaj yeem yuav cov khoom qhuav qhuav. Thiab cav thiab ntoo, zoo li tej ntoo, raug compression thaum qhuav.thiab o thaum ntub.
Npaum ntawm cov phab ntsa ntoo ntawm lub tsev cav tawm los tsis sib xws. Piv txwv li, sab qab teb ntawm lub tsev dries tawm sai, lub crowns nyob rau hauv lub chav tsev, yog hais tias nws yog rhuab, thiab lwm yam tag nrho cov no ua rau tawg ntawm lub beam (cav) thiab, feem ntau txaus ntshai, warping ntawm phab ntsa, ua txhaum ntawm lub lub log geometry.
Nyob rau lub log tsev shrinkage
Cov kws tshawb fawb tau sim ntau xyoo los nrhiav txoj hauv kev los tiv thaiv qhov cuam tshuam ntawm kev ziab tsis sib xws ntawm lub tsev ntoo. Thiab tseem lawv nrhiav tau ib txoj kev daws teeb meem - lawv tau tsim ib lub teeb thiab log shrinkage compensator, ua tsaug rau cov phab ntsa ntawm lub tsev cav ntoo tau ua kom ruaj khov thiab sov.
Yav dhau los, cov phiaj xwm tau siv los ua lawv, uas tau muab tso rau hauv cov ncej ntsug thiab, raws li cov yas ntawm lub cav ntoo qhuav tawm, lawv raug tsoo los yog squashed. Tam sim no muaj ntau lub tuam txhab uas tsim cov khoom tsim rau cov tsev ntoo, suav nrog cov ntsia hlau thiab lub caij nplooj ntoo hlav nthuav dav.
Screw expansion joints
Lawv yog siv los txhim kho cov ncej ntsug los ntawm sab saud (los ntawm hauv qab) ntawm lub terraces ntawm lub tsev ntoo, qhib verandas, sab saud, thiab lwm yam. Nws yog ib qho yooj yim mus ua hauj lwm nrog lawv, koj muaj peev xwm tswj thiab kho cov geometry ntawm lub log tsev koj tus kheej tsis muaj kev koom tes ntawm pab. Cov ntsia hlau shrinkage compensator yog ib lub bolt khov kho rau lub hauv paus phaj, uas yog tsau rau hauv lub hauv paus ntoo nrog tus kheej tapping screws. Nyob rau lwm sab muaj ib tug clamping phaj nrog ib tug txiv ntseej. Raws li cov khoom ntoo dries, nws yuav tsum tau twisted. Thaum xub thawj, nws muab tso rau hauv lub xeev untwisted. Lub clamping bar tseem ruaj khov rau lub cav lossis ntoo.
Nws yog ib qho tsim nyog yuav tsum tau xyaum lub qhov txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nkag mus rau hauv nws. Hauv thawj xyoo, qhov feem pua ntawm shrinkage ntawm lub log tsev yog qhov loj tshaj plaws, koj yuav tsum tau ua raws li cov kev hloov pauv thiab kho cov geometry ntawm lub tsev nrog cov txiv ntseej txhua hli.
caij nplooj ntoos hlav expansion pob qij txha
Caij nplooj ntoos hlav compensators muaj lub caij nplooj ntoos hlav steel muaj zog, ntev tus kheej tapping ntsia hlau thiab capercaillie. Lawv ceev thiab pab txhawb cov txheej txheem ntawm shrinkage ntawm lub cav tsev thiab nyob rau tib lub sij hawm nrees fasten lub crowns rau ib leeg. Txhim kho lawv yog ib qho yooj yim. Thaum lub sij hawm tsim kho ntawm lub tsev cav, lawv tau screwed rau hauv lub pre-drilled qhov nrog ib tug xyaum. Caij nplooj ntoos hlav compensators yuav tsis corrode, vim hais tias lawv raug kho nrog ib tug tshwj xeeb tiv thaiv. Lawv txoj haujlwm tsis tas yuav tsum tau tswj hwm, lawv yuav "automatically" saib xyuas lub shrinkage ntawm lub log tsev thiab, yog tias tsim nyog, them nyiaj rau nws.
Caij nplooj ntoos hlav shrinkage compensator nqi ntau heev. Yog li ntawd, txhawm rau txuag nyiaj, koj tuaj yeem siv nws los kho tsuas yog sab sauv ntawm lub tsev cav, thiab kho hauv qab nrog cov ntoo dowels. Tom qab tag nrho, thawj cov yas yog muab nrog cov khoom tsim nyog, thiab qhov hnyav ntawm lub ru tsev thiab lub ru tsev tsis txaus, yog li cov kev cuam tshuam loj heev yuav tsim, uas yuav ua rau kom sov.
Cov txiaj ntsig ntawm Lub Caij Nplooj Ntoos Hlav Shrinkage Compensator
Lub caij nplooj ntoos hlav sib dhos tsis yog tsuas yog them nyiaj rau qhov shrinkage xwb, tab sis kuj muab cov phab ntsa ntawm lub tsev log nrog qhov hnyav txog 100 kg / s. Thiab ntawm lub cavlos yog lub nqaj yuav tsum tau nruab nrog li 4 lub bolts, yog li muab lub siab ntawm 400 kg / s. Ua tsaug rau qhov no, yuav tsis muaj qhov sib txawv ntawm cov yas thiab tsis tas yuav tsum muaj cov caulking. Cov phab ntsa ntawm lub tsev ntoo yuav tsis warp, thiab chav yuav sov thiab cozy.
Siv cov khoom siv hauv tsev xws li shrinkage compensators hauv kev tsim lub tsev ntoo, ntau yam teeb meem yuav zam tau yav tom ntej. Nws yuav ua tau kom tsis nco qab txog qhov rwb thaiv tsev tas li thiab, qhov tseem ceeb tshaj plaws, tsis txhob ntshai tias lub geometry ntawm tag nrho lub tsev log yuav raug ua txhaum.
