Wooden I-msebe. Ukucacisa, isicelo

abenzi yanamhlanje mihla zisiwe emarikeni lwasekhaya yokwakha izinto uluhlu enkulu iimveliso ezisemgangathweni, kubandakanywa kuthandwa kutshanje ukwandisa waqalisa ukoyisa I-Imiqadi, nto leyo abe imilo ekhethekileyo cross-yecandelo. Indima ngumkhinkqi idlala ngamaplanga (oko kukuthi, i-OSB preform), nto leyo ethe phakathi nemivalo. ekwakheni ubuhlobo kwesakhiwo lwenziwa kusetyenziswa iglu ekhethekileyo beengxenye ngomthi asebenza phantsi imithwalo emikhulu. I-umqadi, iimpawu zobugcisa kuya kuqwalaselwa ngezantsi, ibhekisela neenkokeli zoyilo zokwakha kakhulu mihla kakuhle.

Iimpawu I-msebe

iinkcukacha I-beam uye phezulu ngokwaneleyo. Ngokuxhomekeke kuyilo yayo ezizodwa, le zokwakha iba imigangatho ephakamileyo bokuxhathisa kwaye ukuqina, nto leyo eyenza kunokwenzeka ukusetyenziswa kwayo kwiindawo imithwalo enzima.

Ukusetyenziswa I-echweliweyo

Ngenxa yokuba iinkcukacha I-umqadi ezihle kakhulu, iye yasetyenziswa ngempumelelo:

• ekwenziweni yophahla;
• njengoko element wenqununu ekwakhiweni ndawo;
• Ayanda system mansard;
• kuba ulwakhiwo lophahla;
• ngexesha ukwakhiwa isakhiwo yesakhelo;
• njenge itheko kwinkqubo formwork (formwork girder).

Kwimeko nganye kwezi embodiments ukusebenzisa izinto zokwakha lisebenza element esisiseko, ngokuba livuma imithwalo eninzi kunene.

Ukukwazi ukusebenzisa izinto kokwakhiwa isizukulwana esitsha ivula inani elikhulu ngamathuba kwishishini lokwakha kwaye kunceda ukusombulula iingxaki ezininzi ezinxulumene nokusingqongileyo, iindleko eziphezulu izinto, iindleko eziphezulu, yaye yokungabikho kwexesha njengeyunithi.

Wooden I-, iyimithi; iimpawu kunye neempawu

Naziphi na izinto zokwakha ingachazwa njengento HIV kunye icala elibi. At the I-ngeeplanga wood eziliqela neengxaki, Noko ke, ilifa eziluncedo ezininzi ivumela kuluncedo ukwaba umbandela phakathi kwabanye.

I-imiqadi kufuneka iinkcukacha zilandelayo:

• Ukukwazi ukumelana imithwalo emikhulu. Oku kunegalelo I-ezimilise icandelo iimpawu umnqamlezo ukuba kunyuke uphawu kuthelekiswa amacandelo uxande okanye setyhula emnqamlezweni. Ukongeza, I-imiqadi, iimpawu zobugcisa apho abe umthamo omkhulu umthwalo, anokuba iindidi zobungakanani, eyenza kube lula ukukhetha ubude elilelona kubagubungela kweminwe enkulu.
• inkqubo yokufaka elula. Ngenxa kuyilo ekhethekileyo imveliso kunye nobunzima encinci kuba ngokukhawuleza nangokulula enze umsebenzi indibano ngaphandle kokusebenzisa uyaziphakamisa izixhobo. Weight I-echweliweyo kuba ngaphantsi kakhulu kunalowo ngekhonkrithi okanye ebuntsimbi nqaku, ngenxa yesi sizathu, ukusebenza ngezinto ezifana lula yaye kulula kakhulu.
• lokuhlola enoqoqosho. Ngenxa ukuphakama aphantsi ngokwentelekiso candelo i- yemiqadi yokuhlanganisa iinkuni osetyenzisiweyo imali.
• Inqanaba aphantsi conductivity thermal. Xa kuthelekiswa ne imveliso ngesinyithi okanye ufakelo lwesamente, izakhiwo ngomthi baligcine ubushushu nokuthintela kwii-abandayo.

Imilinganiselo umbandela kwenza kube lula ukusingatha umthwalo kwaye nibanike nezinye iimpawu ezikhethekileyo zobugcisa, ngenxa apho ukusebenza ixesha elide kunye umthwalo aphezulu kwi-I-imiqadi ayitshintshi zejometri parameters zayo, akubangeli deformation kunye genge, elisuke kakhulu ubomi isakhiwo ngokwaso.

beam I: ezizodwa zobugcisa

iimpawu ezikhethekileyo lobugcisa bala izinto angavela kuphela ukuba usebenzisa kakuhle kuzo zokwakha nokuhambelana nemithetho zokusebenza. Phambi kokuba ukwakha zinonxibelelwano kufuneka wenze ubalo lasekunene I-beam cross-amacandelo dimensions ezigoso kunye nomthwalo (kuthathelwa ingqalelo yayo), ilungelo lokukhetha inkxaso efanelekileyo kunye nezinto ukulungiswa.

I beam (I-umqadi) ngokungqinelana GOST kunye što AISU standard kulawulwa ngolu hlobo lulandelayo: GOST - 26020-83 izikhululo AISU 20-93.

Yintoni efanele kuqwalaselwa xa ufaka le I-echweliweyo

abakhi abanamava bayazi ukuba kubagubungela kweminwe elide kungafuna imiqadi ezinkulu cross-amacandelo - ukuze ukwakhiwa a kuphambuka phantsi umthwalo. Efunekayo ngexesha ufakelo idlulela izixhobo khumbula ukuba ngenxa yokugoba imikhosi eziphambili umthwalo kwenza ebhantini intonga yokusebenza asezantsi kakhulu ekusoluleni. Ukuba iindonga hayi kubalwa okanye uqikelelo kuba ezingachanekanga, isiphumo ukugotywa, baya kuphulukana uzinzo zabo, kwaye Iqonga liya kuba mgangathweni, "ukudlala". Yenza izibalo ekunene kwaye uphephe misinga elizayo H-echweliweyo zinokuba specialist kuphela.
