1. Dab tsi yog Shoring Props?
Shoring Props, tseem hu ua props, steel shores, los yog adjustable shoring props, yog qhov tseem ceeb ntsug load-cov kabmob nyob rau hauv lub formwork txhawb system ntawm kev tsim kho tej yaam num. Lawv yog siv los dais cov ntsug loads thaum lub sij hawm ua vaj tse thiab kev tsim kho, hloov lawv mus rau hauv av los yog cov qauv qis kom ntseeg tau tias cov khoom vaj tse xws li kab teeb, slabs, thiab txhua kab tsis deform los yog dab dej ua ntej lawv lub zog ua tau raws li cov qauv tsim. Nws yog tsuas yog tsim los ntawm lub raj sab nraud, lub raj sab hauv, kho cov txiv ntoo, lub hauv paus, lub phaj sab saum toj, thiab cov khoom siv xauv. Qhov siab adaptation yog ua tiav los ntawm kev kho qhov nthuav dav thiab kev cog lus ntawm lub raj sab hauv, ua tau raws li qhov xav tau ntawm qhov sib txawv hauv pem teb qhov siab thiab loads.
2. Core Functions thiab Application tseem ceeb
1). Dais ntsug Loads thiab xyuas kom muaj kev nyab xeeb ntawm cov qauv
Lub luag haujlwm tseem ceeb ntawm Shoring Props yog los nqa cov khoom ntsug xws li pob zeb ua tus kheej - hnyav, formwork hnyav, cov neeg ua haujlwm tsim kho, thiab cov khoom siv hnyav. Lawv cov kabmob muaj peev xwm ncaj qha txiav txim siab txog kev nyab xeeb ntawm kev txhawb nqa. Lub peev xwm muaj peev xwm ntawm cov pa roj carbon zoo tib yam shoring props yog ntau dua lossis sib npaug li 15kN, thiab hnyav -cov khoom siv tuaj yeem ncav cuag 50-100kN, uas tuaj yeem tiv taus qhov ntsug siab ntawm qib sib txawv ntawm cov pob zeb ntawm C30 txog C80. Nyob rau hauv pem teb kev tsim kho ntawm 32-zaj dab neeg chaw ua haujlwm lub tsev, muab kauv shoring props nrog lub peev xwm ntawm 30kN tau siv nrog qhov sib nrug ntawm 1.2m × 1.2m. Thaum lub sij hawm ua vaj tse, lub shoring props tsis muaj kev sib haum xeeb los yog deformation, thiab hauv pem teb flatness sib txawv yog tsawg dua los yog sib npaug li 3 hli, ua tau raws li cov kev cai ntawmCode rau kev lees txais kev tsim kho zoo ntawm cov khoom siv pob zeb(GB 50204-2015), zam qhov kev pheej hmoo ntawm kev puas tsuaj los ntawm kev txhawb nqa tsis ua haujlwm.
2). Precise Height Adjustment to Adapt to Multi-Scenario Xav Tau
Shoring Props ua tiav qhov siab zoo los ntawm kev kho cov txiv ntoo lossis cov khoom siv hydraulic. Qhov kev hloov kho feem ntau yog 1.0-3.5m (kev hloov kho tshwj xeeb tuaj yeem ncav cuag 5.0m), thiab qhov kev hloov kho raug tsawg dua lossis sib npaug li 5 hli, uas tuaj yeem hloov kho rau qhov siab sib txawv (2.8m, 3.0m, 3.3m, thiab lwm yam) thiab cov qauv qhov siab sib txawv. Hauv kev tsim kho hauv qab daus siab - cov qauv qis qis, cov shoring props tuaj yeem ua kom cov formwork txhawb nqa nto kab rov tav los ntawm kev hloov qhov siab, kom ntseeg tau qhov tseeb ntawm cov khoom ua vaj tse; nyob rau hauv choj lub thawv girder pouring, lub formwork elevation deviation yuav raug kho los ntawm kev nplua -tuning lub sab saum toj phaj siab, xyuas kom meej tus choj kev sib raug zoo raws li tus qauv tsim. Nyob rau hauv txoj kev choj kev tsim kho ntawm tus choj hla hiav txwv, hydraulic shoring props tau siv, thiab los ntawm kev hloov kho synchronous, qhov siab sib txawv ntawm 120 shoring props tau tswj tsis pub dhau 2 hli, kom ntseeg tau qhov zoo ntawm lub thawv girder pouring.
3). Txhim kho kev tsim kho kom zoo thiab txo lub sijhawm tsim kho
Shoring Props txais ib qho qauv tsim nrog lub teeb ib qhov hnyav (20-30kg rau carbon steel hom, 12-18kg rau aluminium alloy hom). Tsis xav tau cov khoom nqa loj, thiab 2 tus neeg ua haujlwm tuaj yeem ua tiav kev teeb tsa thiab tshem tawm nrog kev teeb tsa nrawm ntawm 30-40 daim / teev, uas yog 4-6 npaug ntawm cov khoom siv ntoo (5-8 daim / teev). Siv 1000㎡ pem teb kev tsim kho ua piv txwv, kev teeb tsa ntawm shoring props tsuas yog siv sijhawm 25-30 teev, txuag 80-100 teev piv nrog cov khoom siv ntoo thiab ua kom lub sijhawm siv sijhawm ntev li 4-5 hnub. Tsis tas li ntawd, cov khoom siv shoring tuaj yeem muab tais thiab muab tso rau tom qab disassembly, yooj yim rau kev thauj mus los thiab khaws cia, txo tus nqi ntawm qhov chaw ua haujlwm; cov khoom tseem ceeb tuaj yeem rov qab siv tau 150-200 zaug nrog cov nqi kho mob qis, ntxiv rau kev txhim kho cov nqi tsim kho.
4). Txhim kho kev txhawb nqa kev ruaj ntseg thiab txo cov kev pheej hmoo ntawm kev nyab xeeb
Cov yeeb nkab sab hauv thiab sab hauv ntawm Shoring Props yog ua los ntawm cov kav hlau tsis sib haum lossis siab - zaus welded kav, ua ke nrog kev txhawb nqa rib tsim, uas muaj qhov zoo ntawm kev khoov sab nraud thiab tsis ruaj khov. Lub hauv paus phaj yog ua los ntawm thickened steel phaj (thickness Ntau dua los yog sib npaug rau 8 hli), ua rau thaj chaw sib cuag nrog hauv av, txo qhov siab ntawm ib chav tsev (tsawg dua los yog sib npaug rau 0.3MPa), thiab zam cov shoring props sinking rau hauv av; lub phaj saum toj kawg nkaus yog nruab nrog cov khoom siv los tiv thaiv- cov roj hmab nplaum los txhim kho kev sib txhuam nrog cov formwork thiab tiv thaiv kom tsis txhob ntog. Hauv tag nrho -qhov chaw txhawb nqa kev tsim kho hauv qab daus, hnyav- lub luag haujlwm shoring props nrog qhov sib nrug ntawm 1.0m × 1.0m tau siv, ua ke nrog cov hlua khi kab rov tav los ua ib qho kev txhawb nqa tag nrho. Tom qab kev ntsuas kev thauj khoom, qhov siab tshaj plaws kev sib haum xeeb yog tsawg dua lossis sib npaug li 2 hli, tsis muaj kev co lossis tsis ruaj khov, ua kom muaj kev nyab xeeb zoo ntawm kev ua haujlwm siab - qhov siab.
3. Khoom siv thiab txheej txheem txheej txheem
Cov khoom siv carbon hlau: Cov raj sab nraud thiab cov raj sab hauv yog ua los ntawm Q235 / Q355 qis- carbon steel lossis 40Cr alloy steel, ua raws li GB / T 700-2006 tus qauv, nrog lub zog tensile Ntau dua lossis sib npaug rau 370MPa thiab lub zog tawm los ntau dua lossis sib npaug rau 235MPa;
Aluminium Alloy Khoom: 6061-T6 aluminium alloy yog siv, ua raws li GB / T 3190-2022 tus qauv, nrog lub zog tensile Ntau dua lossis sib npaug rau 260MPa thiab lub zog tawm los ntau dua lossis sib npaug rau 240MPa, thiab muaj zog corrosion kuj;
Kev siv thev naus laus zis: Cov kav hlau steel txais seamless lossis siab - zaus vuam tshuab, nrog vuam qhov siab Ntau dua lossis sib npaug li 3 hli, tsis muaj qhov hws lossis tawg, tsim nyog los ntawm kev kuaj pom qhov tsis zoo; threads txais dov tshuab, nrog precision mus txog 6H qib, thiab kev hloov kho du yam tsis muaj jamming;
Los tiv thaiv- Kev Kho Corrosion: Qhov saum npoo ntawm carbon steel shoring props yog kub-dip galvanized (zinc txheej thickness Ntau dua los yog sib npaug rau 85μm) los yog electrostatically sprayed, nrog ntsev tsuag corrosion kuj ntau dua los yog sib npaug rau 500 teev; aluminium alloy shoring props txais kev kho mob anodization (oxide zaj duab xis Ntau dua los yog sib npaug rau 15μm) nrog zoo corrosion kuj;
Cov cuab yeej siv kev nyab xeeb: Nruab nrog cov khoom siv xauv dual (kho cov txiv ntoo + xauv tus pin) kom tsis txhob xoob thaum siv; hydraulic shoring props yog nruab nrog lub siab tshaj kev tiv thaiv li qub kom tsis txhob overloading.
