Amaphutha Okuqeda I-Power Trowel: Amamaki Okusha, Amagagasi, Isikhathi kanye Nokulungiswa Kwe-Angle Ye-Blade

Amaphutha okuqeda i-power trowel awavamile ukuvela endaweni eyodwa kuphela. Amamaki okusha, amagagasi, imigqa yokukhuluma kanye nemigqa ye-blade ngokuvamile avela ngoba isimo se-slab, i-blade pitch, isivinini se-rotor noma isikhathi azisebenzi ndawonye. Indawo yokusetha umshini ezwakala kahle ntambama ingaba namandla kakhulu ngemizuzu engamashumi amabili ngaphambili. Ikhonkrithi iyashintsha ngokushesha ngenkathi ishona, ngakho-ke umqhubi kufanele aqhubeke nokufunda phansi esikhundleni sokukhiya ekhoneni elilodwa le-blade noma ijubane elilodwa.

Amaphutha Okuqeda I-Power Trowel: Lokho Okukutshelayo Phansi

Ngaphambi kokushintsha konke emshinini, bhekisisa uphawu. Isiqephu esimnyama, igagasi kanye nomugqa okhulumayo kuyizinkinga ezahlukene. Ukuziphatha zonke “njengezimpawu ze-trowel” kuvame ukuholela ekulungiseni okungalungile. Umsebenzi wokuqala ukuhlonza uphawu, bese usebenza emuva ngokusebenzisa isikhathi, ukusetha ama-blade, isimo somshini kanye nezigaba zokuqeda zakuqala.

Kungani I-Power Trowel Ishiya Amamaki Okusha?

Amamaki okushiswa kwe-power trowel awawona njalo uphawu lokuthi kukhona okungahambi kahle. Ukufaka i-hard trowel ngokwemvelo kwenza ungqimba oluphezulu lwekhonkrithi lube lude kakhulu, futhi isiqondiso semboni sibeka lolu ngqimba oluqinile cishe ubukhulu obuyi-1–4 mm . Ngokuvamile lubukeka lumnyama kunekhonkrithi engaphansi, ngakho-ke ubumnyama obuthile bungaba yingxenye yokuqeda okune-hard trowel kunokuba kube umonakalo ku-slab.

Isibonakaliso sesixwayiso sinombala ongalingani. Uma indawo eyodwa imnyama, icwebezela noma imakwe kakhulu kunezinye, bheka ukuthi umshini usetshenziswe kanjani lapho. Amaphasi amaningi kakhulu, ingcindezi ephezulu yendawo noma izimo ezahlukene zokusetha kulo lonke i-slab konke kungashiya umehluko obonakalayo. Isiqondiso esifanayo semboni siphawula ukuthi ungqimba oluqinile oluncane olungaphezu kuka- 1 mm lungaguga ngokushesha ngaphansi kwethrafikhi encane evame ukuba khona yama-forklift. Imininingwane eyengeziwe ngalezi zinkinga zokuqeda phansi ingatholakala kulokhu ingxoxo yobuchwepheshe mayelana neziphambeko phansi kokhonkolo olufakwe ngensimbi .

Iphimbo le-blade libalulekile ngoba iphimbo eliqinile lithinta indawo encane ebusweni. Ingcindezi endaweni yokuxhumana iyakhuphuka. Lokho kuyasiza kamuva enkambisweni yokuqeda, kodwa ukuphonsa amaphimbo ngokushesha kakhulu kungenza umshini ukhulume noma ushiye imigqa eqinile. Iphimbo eliningi liwusizo ngesikhathi esifanele. Ngesikhathi esingafanele, limane linikeza phansi irekhodi elicacile lephutha.

Kungani I-Power Trowel Ishiya Amagagasi?

Ukuphela kwekhonkrithi okunamagagasi kuvame ukuqala lapho i-slab isathambile kakhulu ukuba ingathwala umshini kahle. Ucwaningo olufingqiwe ku-Concrete International lubeka ukuqala kwamandla okuntanta cishe ku- 50–150 psi (0.3–1.0 MPa) ukumelana nokungena . Iningi labasebenzi ngeke lihlole ukumelana nokungena eceleni kwe-slab ngayinye, kodwa inombolo iyasiza ukuchaza izimpawu zasensimini.

Uma umshini ucwila kakhulu, usunduza udaka phambi kwezinsika noma ushiya indawo ethambile yokugoqa ngemuva kwawo, ukhonkolo cishe awukakulungeli. Ukulinda isikhashana kungasindisa umsebenzi omningi wokulungisa kamuva.

Akuwona wonke amagagasi aqala nge-power trowel, futhi. Ukusikeka okungekuhle noma ukuntanta okungalingani kungashiya izindawo eziphakeme neziphansi ngaphambi kokuba umshini ufike. umshini wokusikeka ukhonkolo Isebenza ekuqaleni kwenqubo, isiza ekushayeni nasekulinganiseni ukhonkolo omusha ngaphambi kokuba kuqale ukuphotha kokugcina. Uma i-slab ingalingani kakade esigabeni sokuphotha, ukucindezela okwengeziwe kwe-blade kamuva ngeke kuyiguqule ngokuyisimangaliso ibe yiphansi eliyisicaba. I-power trowel ingathuthukisa ubuso; ayikwazi ukwakha kabusha i-geometry ye-slab empofu.

I-Concrete Ikulungele Nini Ukukhishwa Kwamandla?

Isikhathi se-power trowel akufanele sisekelwe ewashini kuphela. Idatha yocwaningo lwenkontileka ye-ASCC ikhombisa ukuthi izinga lokushisa elingakanani elingashintsha isikhathi sokulinda. Abankontileka babike ukuqala okulindelekile kokuntanta kwamandla cishe amahora angu-4.25 ku-10°C (50°F) , amahora angu-2.75 ku-20°C (70°F) kanye namahora angu-1.75 ku-30°C (90°F) .

Isiqondiso esifanayo se-ASCC sithi amandla antantayo avame ukuqala lapho unyawo lushiya ukugoba okungaba ngu- 6 mm (1/4 in.) noma ngaphansi futhi amanzi abonakalayo aphumayo ehambile. Lezi yizinkomba zasensimini kunokuba yimithetho eqinile yeslab ngayinye, kodwa ziwusizo kakhulu kunokuthi, “Sihlala siqala ngemva kwamahora amathathu.” I-Concrete ayinawo iwashi.

Kwenzekani Uma Uqala Kusenesikhathi?

Ukuqala kusenesikhathi kungashiya amagagasi, kucindezele unamathisele nxazonke bese kuvala indawo ngaphambi kokuba amanzi nomoya kuqede ukukhuphukela phezulu. Isiqondiso semboni sibika amabhamuza ekhonkrithi asukela cishe ku -6 kuya ku-100 mm (1/4 kuya ku-4 intshi) ububanzi kanye nokujula okungaba ngu-3 mm (1/8 intshi) . Ukwehlukaniswa kwe-delamination kungasakazeka ezindaweni ezinkulu kakhulu, ngakho inkinga ingadlula kakhulu amamaki ambalwa abonakalayo.

Okuqukethwe komoya kungenza inkinga ibe yimbi kakhulu ezitezi eziqinile eziqinile. Isiqondiso se-ACI esicashunwe ezincwadini zemboni sixwayisa ngokuthi ukuqhekeka nokwehlukaniswa kwezakhi kuba yinto ekhathazayo lapho okuqukethwe komoya okuphelele kukhuphuka ngaphezu kuka- 3% . Lokho akusho ukuthi phansi kuyawa lapho inani lifinyelela ku-3.1%, kodwa kuyisikhumbuzo esiwusizo sokuthi akuyona yonke inkinga yokuqeda eqala ngomqhubi noma emshinini.

Kwenzekani Uma Uqala Sekwephuzile?

Shiya i-slab ibe yinde kakhulu bese kuba nzima ukuyivala. Abasebenzi bavame ukusabela ngokungeza i-blade pitch eyengeziwe kanye nesivinini esengeziwe. Lokho kungadala ukuxokozela, imigqa ye-blade ebukhali noma ukusha okunamachashaza. Ifasitela lokuqeda eliwusizo lihlala phakathi kwekhonkrithi ethambile kakhulu ukuba ingathwalwa umshini kanye nekhonkrithi enzima kakhulu ukuphendula ngokulinganayo.

Kufanele Usebenzise Iphimbo Elingakanani Le-Trowel Blade Elinamandla?

Ayikho i-engeli eyodwa ye-trowel blade enamandla kulo lonke umsebenzi. Ukudlula kokuqala kudinga ukuthintana kakhulu kwe-blade phansi. Njengoba i-slab iqina, ama-blade angaphonswa kancane kancane ukuze kufakwe ingcindezi eyengeziwe ebusweni. Ububanzi bokusebenza komshini, uhlobo lwe-blade kanye nokulungiswa kwe-pitch nakho kuthinta indlela opharetha angazilandela kalula ngayo izimo zekhonkrithi ezishintshayo.

Osonkontileka beqhathanisa okuhlukile imishini yokudonsa amandla Ngakho-ke kufanele kubheke ngale kwamandla enjini kuphela. Ububanzi bokusebenza, ukumiswa kwe-blade, ukwakheka kokulawula kanye nokulungiswa kwephimbo konke kubalulekile ngesikhathi somsebenzi wokuqeda wangempela, ikakhulukazi lapho i-slab isuka ekuntanteni iye ekugcineni.

Uma kuvela ukuxokozela ngokushesha nje lapho ama-blade ephakanyisiwe, buyisela phansi iphimbo bese ubheka umshini. I-ASCC ihlukanisa iphethini elula yokuxokozela ebonakalayo kumaki we-trowel wangempela onesimo esigobile, kuyilapho izinto zokuqeqesha ze-ACI ezishiwo yi-ASCC zixhumanisa iphimbo lephimbo eliningi nebhodi lokuwasha noma izindawo zokuxokozela ezingafanele.

Uma ukunciphisa iphimbo kungasizi, hlola ama-blade kanye nezingalo ze-trowel. Ama-blade agobile, ukulungiswa okungalingani noma izingxenye ezikhululekile kungabonakala njengenkinga yekhonkrithi uma inkinga yangempela iwumshini. Kushibhile ukuhlola umshini kunokuphikisana namamitha-skwele amaningana ekhonkrithi eqinile.

Ingabe Ijubane Le-Rotor Libangela Amamaki E-Power Trowel?

Ijubane le-rotor libalulekile, kodwa ayikho i-RPM enengqondo yendawo yonke yephansi ngalinye. Usayizi womshini, ububanzi be-blade, ukuqina kwekhonkrithi kanye nokuphela okudingekayo konke kushintsha indlela ama-blade asebenza ngayo. I-pass yesivinini esiphezulu efanelana ne-slab eqinile ingase ibe namandla kakhulu kukhonkrithi ethambile.

Ngezitezi ezihlotshisiwe noma ezinemibala, isiqondiso se-ASCC siphawula ukuthi amaphasi ambalwa kanye nesivinini sokujikeleza esiphansi kungasiza ekunciphiseni izindawo ezimnyama noma ezibukeka zishile. Isivinini kufanele silandele isimo sephansi kunomkhuba womqhubi. Okufanayo kusebenza ekuphinjeni kwe-blade: kokubili kudingeka kushintshe njengoba ukhonkolo ushintsha.

Ikhwalithi Yokuqeda Iqala Ngaphambi Kokufika Kwe-Power Trowel

Ukuqeda okuhle kuqala ngaphambi kokudlula komshini kokugcina. Ukufinyelela, ukulungiswa kwesisekelo esingaphansi, ukukala indawo, ukuphathwa kwezinto kanye nokusika konke kuthinta indlela ukuthululwa kukakhonkolo okuhamba kahle ngayo. Ezindaweni zokwakha ezincane, izithwali ze-skid steer zokulungiselela indawo nokubeka amazinga ingaphatha imisebenzi efana nokulinganisa, ukugcwalisa i-backfilling kanye nokunyakaza kwezinto ngaphambi kokuba umsebenzi we-slab uqale.

Lokhu akusho ukuthi i-skid steer ilawula ukuqeda okune-trowell ngqo. Ukuxhumana kuphezulu: ukulungiswa komhlaba okungekuhle noma ukuphathwa kwezinto ezingafanele kungenza ukubekwa kube nzima, kuyilapho ukulungiswa kwendawo enhle kunikeza abasebenzi bekhonkrithi indawo yokuqala ezinzile. Ngesikhathi i-power trowel ifika esitsheni, ezinye izinqumo zekhwalithi sezivele zenziwe.

Indlela Yokugwema Izinkinga Zokuqeda I-Power Trowel

Qala nge-slab eyisicaba ngokwanele futhi ungasheshi ungene emanzini abonakalayo aphumayo. Gcina ama-blade ethe tyaba ngesikhathi sokuqala komsebenzi, sebenzisa izindlela ezihambisanayo futhi ugweme ukuchitha isikhathi eside kakhulu engxenyeni eyodwa kunenye. Njengoba ubuso buqina, engeza i-pitch kancane kancane kunokuba konke ngesikhathi esisodwa. Uma kuvela amagagasi, i-chatter noma imigqa emnyama, yima ubheke uphawu ngaphambi kokufinyelela isivinini esengeziwe.

Isimo somshini sihambisana nomkhuba ofanayo. Ama-blade ahlanzekile, ukulungiswa okulinganayo, izingalo ze-trowel eziqondile kanye nokunyakaza kwe-rotor okubushelelezi kwenza umehluko obonakalayo. I-concrete inomkhuba omubi wokukhumbula wonke amaphutha amancane isikhathi eside ngemva kokuba umqhubi esewakhohliwe.

Imibuzo Evame Ukubuzwa Ngokuqeda I-Power Trowel

Kungani i-power trowel yami ishiya amabala?

Isikhathi esingalungile, ukujikijela kakhulu kwe-blade, ukudlula okungalingani, ama-blade agugile kanye nokuguga kwemishini kuyizimbangela ezivamile. Okokuqala thola ukuthi uphawu lumnyama, lunamaza, lugobile noma lubonakala nje ngaphambi kokushintsha izilungiselelo zomshini.
