Konkire kachulukidwe: mitundu kachulukidwe mawerengedwe

osalimba a konkire - ndi limodzi mwa makhalidwe ofunika chuma ichi, chimene ndi dongosolo pacimake. Ndi zambiri ubwino, koma pali drawback, m'kukoma kulemera kwambiri. Ndi akatswiri amenewa kuika pa siteji ya kapangidwe ndi kumanga. Mbali imeneyi n'kofunika kuganizira kwambiri konkire ndi disassembly, m'kati dismantling.

Zochita konkire Anthu ambiri amagwiritsa ntchito osati mafakitale komanso kumanga payekha. Konzani osakaniza akhoza kukhala paokha monga armature ndi kugwirizana ntchito waya wapadera kukhazikitsa analimbitsa dongosolo konkire. Chifukwa ndi cholimba ndi wangwiro kamangidwe.

The mitundu chachikulu cha konkire

osalimba a konkire akhoza zosiyanasiyana, kuti adzapangitsa pa zikuchokera njira. Ngakhale kulemera zimadalira osalimba. Wachinsinsi analimbitsa ndendende pa khalidwe izi, ndikofunikira kuonetsetsa, pakati ena:

• lolemera kwambiri;
• adalemeradi;
• opepuka;
• opepuka konkire.

osalimba a konkire m'nkhani yoyamba yochepa kuti 2500 makilogalamu / mita ^3, zomwe ndi mtengo chidwi. Okonza boma, mtundu uwu konkire ntchito. formulations akhoza muli placeholders zotsatirazi:

• magnetite;
• limonite;
• barite.

kachulukidwe konkire

Pa katundu konkire kachulukidwe penapake m'munsi, ndi 2,200 amene anafunsidwa makilogalamu / mamita ^3. zambiri mwachizolowezi miyala, wosweka zinthu mwala mwa zosakaniza zimenezi, ndi zina zotero. kachulukidwe wa konkire adzakhala m'munsi ngati ndi opepuka konkire. Izi konkire katundu kwa zolimba chitsulo ndi kudzera-ndege. Pankhaniyi chizindikiro chidwi adzakhala 1800 makilogalamu / mamita ^3.

The kachulukidwe ya opepuka konkire

concretes opepuka ndi osalimba wa makilogalamu 500 / mamita ^3. kolowera ndi zina kukodzedwa dongo, ma, perlite ndi polystyrene konkire. Zinthu zimenezi kumatheka zolimba. The kachulukidwe pafupifupi konkire kumadalira osati kokha pa zikuchokera komanso njira kuponyera. Ngati osakaniza akadali zamadzimadzi tikaumbike ntchito makina vibratory, osalimba ukuwonjezeka ndi makilogalamu 100 / mamita ^3.

mawerengedwe a kachulukidwe

osalimba a konkire, mitundu imene yatchedwa pamwambawa, ndiye titsimikize ngati maziko, chiwerengero cha njira mu mayunitsi wa misa. madzi Tisawasale mawerengedwe, ndilo kale 28 masiku kwathunthu asanduke nthunzi khamu la. Izi kupeza phindu lenileni la osalimba a monolith lapansi.

Nthawi zina omanga ntchito deta ambiri, ngati ife tikudziwa kalasi konkire. Mwachitsanzo, kwa kalasi M-200 zimasiyana kachulukidwe mu osiyanasiyana 2385 ndi 2400 mg / mita ³ pamene mtundu M-250 mtengo zonsezi zimatengera mtundu wa 2390 mpaka 2405 mg / mita ^3. Pakuti zizindikiro M-300, M-350 ndipo M-400 kachulukidwe adzakhala osiyanasiyana kuchokera 2400 mpaka 2415; kuyambira 2405 mpaka 2420 ndipo kuyambira 2410 mpaka 2430 makilogalamu / mamita ^3, motero.

Ngati mukufuna kachulukidwe yeniyeni konkire, ndiye inu mukudziwa kuti pa kulemera kwa mita kiyubiki ukuchititsa ndi zolimba chiwembu. Sizoti ndi chiwerengero cha ndodo, koma gawo lawo. Zokonda izi amakulolani kumasulila ndi buku mkati wotanganidwa ndi zolimba kwambiri. Ndiye mukhoza kugwira kuwerengetsera misa. Malinga ndi cholinga ndi maonekedwe a simenti chimene, angagwiritsidwe ntchito ndodo osiyana awiri. Pankhani Kusinthaku awo, iwo akhoza ili pa mtunda wina ndi mzake.

Pofuna kudziwa osalimba a analimbitsa simenti, molondola wapadera Sikuti, kotero kuchuluka kwa zolimba angathe kumwedwa tentatively. Choncho, kupanga mayendedwe konkire ndi pavings amagwiritsidwa ntchito 8 mm zolimba mauna kukula 200 mm. Mu mita imodzi lalikulu la chuma adzakhala anapitiriza 16 mamita ndodo ndiponso ngati osalimba a zitsulo kufika 7850 makilogalamu / mamita ^3, armature misa adzakhala wofanana ndi makilogalamu 6.3.

Pamene izo zifika pa matabwa yopingasa ndi slabs akundithandiza ndi maziko a armature awiri zambiri zimasiyanasiyana mamilimita 12 mpaka 16. Kukula selo utachepa mpaka 180 mamilimita ndi kutalika amakhalabe sichinasinthe. Mu nkhani iyi, armature misa malire kuchuluka kwa makilogalamu 14 25,2. Pakuti cantilever matabwa ndi slabs armature awiri ndi pakati pa 16 ndi 18 mm, ichi ndi choona ngati kukula selo ndi wofanana 130 mm. La utali wonse wa armature 1 mita ³ konkire adzakhala 49 m, pa mlandu umene zolimba misa adzakhala zimasiyana makilogalamu 77,3 kuti 97,8.

The kachulukidwe ya zomangamanga owonjezera

M'pomveka kuganizira komanso njira makoma ofukula ndi mizati. Pankhaniyi, ndi awiri a armature akhoza kukhala wolingana ndi malire a 14 18 mamilimita pamene kuchuluka kwa maselo mu 130 mm. The okwana kutalika akanali yemweyo, koma kulemera adzakhala wofanana ndi malire a makilogalamu 59,2 kuti 97,8.

Mwamsanga pamene inu mukudziwa chiwerengero cha zovekera ndi machulukidwe zingadziŵike kulemera kwa mita kiyubiki wina konkire. Kuyambira kyubu ndi chimafotokozera buku ambiri omwe amachita ndi ndodo zitsulo. Pomaliza pake, buku la simenti analandira, ndiye manambala ndi kuchulukitsa pa chiwerengero lililonse zakuthupi ndi zotsatira akuwonjezeka.

Mawerengedwe a osalimba pa lamba Mwachitsanzo analimbitsa maziko konkire

Kachulukidwe yowona (makilogalamu / M3) akhoza kuchita masamu ndi chitsanzo cha m'munsi tepi womwe wapangidwa konkire kalasi M-300. Pankhaniyi, ife ntchito 16mm ndodo. Pa gawo loyamba voliyumu wotanganidwa ndi armature mu mita kiyubiki zakuthupi. Kuchita izi, ntchito mawerengedwe zotsatirazi: π · R2 · L = 3,14 · (0,008) 2 = 0.003 · 16 mamita ^3.

Choncho, ukonde amatenga simenti 0,997 mamita ^3. Kuwerengetsa kulemera kwa ikuthandizira ndodo ayenera kuchulukitsa mfundo 0,003h7850, potsiriza kupeza makilogalamu 23,6, pamene misa konkire ayenera kuchita masamu ndi kuchulukitsa 0,997h2400. kuwerengetsera The amatithandiza kudziwa zimene unyinji wa simenti ndi 2392,8 kg. Kamodzi mfundo ndi mwachidule, munthu akhoza kupeza kachulukidwe konkire anapezazo izi adzayang'ana motere: 23.6 + 2392.8 = 2416 makilogalamu / mamita ³ .These mwai zimagwiridwa pa siteji ya kamangidwe ka katundu nyumba maziko.

Information za osalimba a konkire

analimbitsa simenti ndi osalimba konkire ayenera kudziwika kwa omanga. Ngati mtengo woyamba wakhala anafotokoza pamwamba, wachiwiri akhale kulankhula. The chizindikiro chachikulu ntchito simenti ndi anachita pachilichonse ndi psinjika, komanso mphamvu. specifications izi zonse osalimba, umene ndi index thupi anatsimikiza mtima kugawa kulemera ndi buku.

Kumangidwa ndi wamba kugwiritsa ntchito mtengo avareji chizindikiro izi, chifukwa zinthu mosiyana, Pakati:

• khalidwe ndi kuchuluka kwa filler ya;
• mtundu wa filler;
• zikuchokera madzi;
• mlingo wa mbewu ya mchenga.

mitundu waukulu kachulukidwe konkire

The zikutanthauza kachulukidwe ntchito kudziŵa makhalidwe ndi ranges ankaona, imene nkhaniyo lagawidwa mitundu 4. Mwachitsanzo, concretes katundu ndi osalimba pamwamba 2500 makilogalamu / mamita ^3. Mapangidwe awa kulengedwa kuchokera fillers ndi, zitsulo, zitsulo zotha ntchito, magnesite, ndipo si ntchito ntchito yomanga dongosolo miyambo. Izi osalimba mkulu m'pofunika kukhala wotetezeka, kotero mwala ntchito yomanga zomangamanga wapadera. The osachepera pafupifupi kachulukidwe Akuti index amene n'chozama kupitirira mtengo wa makilogalamu 500 / mamita ^3. Zoterezi chimake cha nkhani ntchito monga chimateteza fillers. A kumvetsetsa kokwanira kwambiri za kusiyana konkire mu osalimba, zopangidwa ndi mitundu, komanso minda labwino la ntchito akhoza amanenera kuwerenga nkhani ili m'munsiyi.

konkire makamaka lolemera, zomwe zinachitikadi anatchula pamwamba, zikhoza kukhala ndi zopangidwa zotsatirazi: M550, M600, M700, M800, M900, M1000. Lolemera simenti ndi kachulukidwe mu osiyanasiyana kuchokera 1800 kuti 2500 makilogalamu / mamita ^3, kugwiritsidwa ntchito kwa nyumba akuthandiza a mtundu zapansi. Zopangidwa konkire amenewa motere: M350, M450, M500. Opepuka konkire ali osalimba mu osiyanasiyana kuchokera 500 mpaka 1800 makilogalamu / mamita ^3, chizindikiro ^mwina titsimikize ndi kalembedwe zotsatirazi: M200, M250, M300. Makamaka concretes opepuka ndi osalimba wa makilogalamu 500 / mamita ^3, ndi Zizindikiro zawo ali motere: M15, M50, M75, M100, M 150 ntchito mtundu uwu wa zinthu kulenga matenthedwe wosanjikiza kutchinjiriza ndi kukhazikitsa khoma.

Pomaliza

Analimbitsa - osakaniza zitsulo ndi konkire, amene ali wapadera katundu. Kukhalitsa kwake, kudalirika ndi durability zakuthupi analola kuti iye adzapeze ambiri zomangamanga. Pamene angagwiritse zomangamanga zochokera makhalidwe ambiri, monga mmodzi wa iwo amaima konkire kachulukidwe T / M3 kapena makilogalamu / mamita ³ - ichi chikuperekedwa thupi, amene analandira kuyeza chizindikiro ichi. Mwachitsanzo, ngati mukudziwa osalimba, umene uli wofanana 2200 makilogalamu / mamita ^3, n'zotheka kumasulira mtengo uwu ngakhale tonnes pa mita kiyubiki. Pankhaniyi, mtengo uwu unali 2.2.
