Wooden I-danda. Magadzirirwo, kushanda

Modern Vagadziri daily akapa epamba kumusika kuti zvokuvakisa guru-siyana uhwu zvigadzirwa, kusanganisira ichangopfuura vachiwedzera mukurumbira vakatanga kukunda I-matanda, vane chaiwo muchinjikwa-sectional chimiro. Basa kuomarara chinoita plywood (kureva preform OSB), izvo glued pakati mbariro. Structural Bonding rinoitwa kushandisa chaiyo namira nokuda emapuranga zvinhu kuti anoshanda pasi mitoro zvikuru. I-danda, ari hwokugadzira unhu nayo ichakurukurwa pazasi, zvinoreva vatungamiri kupfuura ano uye vakarongeka chivakwa mazano.

Features I-danda

I-danda nokurondedzerwa ane zvakakwana kumusoro. Nokuda kwayo chinokosha design, ichi chivako zvinhu zvava yakakwirira nhanho kurwisa uye kuomarara, izvo chinoita kuti kushandiswa kwayo munzvimbo dzine mitoro inorema.

Kushandiswa I kunemisara

Nokuti kuti I-danda nokurondedzerwa akanaka chaizvo, rave richishandiswa zvinobudirira:

• ari zvaAtemisi pasirin'i;
• sezvo chikuru chinhu pakuvaka pamapuriro;
• Kubhururuka mansard hurongwa;
• pakuvaka pedenga;
• panguva erection pamusoro pamatanda mamiriro;
• somunhu scaffold nokuda formwork hurongwa (formwork girder).

In nerimwe embodiments kushandisa chivako zvinhu kushanda so chinokosha, nokuti anobvuma yakawanda chaizvo mitoro.

Kukwanisa kushandisa zvinhu zviri kuvakwa vezera itsva dzakazonaka zhinji tarisiro pakuvaka indasitiri uye kubatsira kugadzirisa matambudziko akawanda chokuita zvakatipoteredza, kudhura nezvinhu, kudhura, uye kushaya nguva sechinhu chimwe.

Wooden I-matanda: unhu uye mamiriro

Chero hworusvingo zvinhu zvinogona kuzivikanwa somunhu akanaka uye kunaka divi. Zvisinei, panguva I-namatanda omuakasia ane nhamba payakaipira, nhaka mikana yakawanda zvinoita zvinobetsera govera mashoko pakati vamwe.

I-matanda vane zvinotevera nokurondedzerwa:

• Kukwanisa kutsungirira zvikuru zvinorema. Izvi zvinobatsira kuti maitiro I-zvakaumbwa muchinjikwa chikamu wakati yakawedzera mamirire ichienzaniswa rectangular kana dzeraundi muchinjikwa zvikamu. Uyezve, I-namatanda ayo, hwokugadzira unhu vane yakakwirira kutakura, anogona kuva akasiyana-siyana hukuru, zvichiita kusarudza optimum kureba hwekushanda pamaoko guru.
• Simple kugadzwa kwacho. Nokuda chinokosha pamasikiro chigadzirwa uye vakawanda duku kunogona kukurumidza uye kuita zviri nyore basa gungano pasina kushandisa nokusimudza mano. Weight I-matanda zviri zvishoma pane kuti nekongiri kana esimbi article, nokuda kwechikonzero ichi, kushanda zvinhu zvakadai yekudyidzana isingadhuri uye nyore.
• Mari feasibility. Nokuda pfupi yakaderera pakakwirira Chikamu I- joists huni ukapisa kupfuura zvishoma.
• The pasi pamwero chafariz conductivity. Tichienzanisa zvinobikwa simbi kana Akazadzisa kongiri, yematanda zvivako varambe kupisa uye kudzivisa kupinda kuti chando.

The kukura acho anoita kuti zvive nyore kuita mutoro uye kupa vamwe nevamwe zvekushandisa features, nokuda izvo kwenguva oparesheni uye inonyanya mutoro pamusoro I kunemisara haachinji ayo geometrical parameters, haakonzeri deformation uye cracking walnut, izvo yekudyidzana rinokoka upenyu chacho pachacho.

I danda: michina nokurondedzerwa

Nevamwe hwokugadzira zvechadenga mashoko anogona kuonekwa chete kana zvakanaka kushandisa navo kuvaka uye zvaidiwa uchishandisa mitemo. Usati kuvaka bindepinde vanofanira kuita zvakanaka kukarukureta kuti I-danda muchinjikwa zvikamu ari kukura, makakombama uye mutoro (kufungisisa yayo), kodzero yokusarudza rutsigiro zvakakodzera uye kugadzira zvinhu.

I danda (I-danda) maererano GOST uye što AISU mureza inodzorwa sezvinotevera: GOST - 26020-83 nhepfenyuro AISU 20-93.

Chii chinofanira kufungwa kana kugadzwa zviri I kunemisara

vavaki ruzivo vanoziva kuti ipedze refu span kungada matanda makuru muchinjikwa zvikamu - kuti kuvakwa asingadi vanokunga pasi mutoro. Inodiwa panguva kugadzwa pindana mano yeuka kuti somugumisiro vaikunga chikuru mutoro mauto kuita pamusoro uchishandisa tsvimbo ezasi bhandi kunonyanya pamusoro ndichisveerera. Kana masvingo zvisina akaverenga kana vanofungidzira kuratidza kururama, nemhaka vachikotama, vacharasikirwa isimbe dzavo, uye pasi zvichaita murombo quality, "kutamba". Ita zvakanaka Masvomhu uye kudzivisa ramangwana dzegirini H-matanda zvinogona chete kuva nyanzvi.
