Nhasi, Savo Kusić inotarisa pa mahwindo emapuranga, wood-aluminium Mahwindo, mahwindo etsika, gonhi uye zvikumbiro zvekotesheni Ichi chinyorwa chinoramba chiri chehunyanzvi hwekuchengetedza uye hachisi chinyorwa chekutengesa chazvino chemapuranga ekuveza.

Chinangwa uye kupatsanura kwekutanga

Mapanera ekuveza anoshandiswa kugadzira magonhi, kupfekedza madziro, fenicha yekugara, nezvimwe. 

Mapuranga emapuranga akakamurwa kuita veneered chete kune rimwe kana mativi ese uye asina kuvharwa; jecha kumativi ose uye asina jecha; kune mahwendefa ezvakajairwa uye kuwedzera kwechokwadi; pamapuranga akanamirwa netsvina dzekugadzira uye pane zvakanamirwa necasin glues. Makuro emahwendefa aya akapihwa mutafura 8.

Maererano nemhando yehuni yemashizha, mapuranga asina kuvharwa anogadzirwa mumhando nhatu: A, AB uye B (tab. 9).

Mapuranga ekuveza akajairwa anogadzirwa mukirasi I uye II. Mapaneru eKirasi I akafukidzwa nemucheka wakachekwa wekirasi I neII.

Kusarudzwa kwemhando dzeveneer yemapuranga ekuveza inoitwa maererano nedata kubva patafura. 10.

Ukobvu hwezvikamu zvese zvepepa rega rega remapofu evhavha yemapuranga asina kuvharwa anofanira kunge ari emapuranga eukobvu.16ku 35 mm - 3,6 mm, kuti ndiro dzipere35 mm- 4,0 mm.   Kune akavharwa mapaneru, ukobvu hwekucheka veneer kunotarirwa zvinoenderana nechiyero chinoshanda. Mune mapaneru akagadzirirwa kugadzira ngoro, ukobvu hwekucheka veneer kunofanirwa kuve 1,5 mm.

Kuvakwa kweiyo musimboti uye veneers

Mapuranga ekuveza anogadzirwa kubva munyoro, softwood uye birch huni. Muchikamu chimwe nechimwe, slats inofanira kuva yemhando imwechete yehuni. Iyo slats mu slab inogona kunamirwa kana kusungirirwa. Kuenderera mberi kwemaslats mumaplateti pamwe nehurefu kunofanirwa kuitwa zvakachinjana nedaro riri pakati pekuenderera mberi kwemaslats ari padyo zvishoma.150 mm. Kune zvivako zvinotsigira, kuenderera mberi kwema slats pamwe chete nehurefu hakubvumirwi.

**Mufananidzo8: Chimiro chebhodhi rekuveza; H - ukobvu; L - kureba: B - upamhi **

Mashizha emapuranga asina kuvharwa anofanirwa kugadzirwa nebirch, alder, beech kana pine veneer iyo mhando isiri pasi pemhando BB zvinoenderana neyakajairwa plywood, uye mapepa emapuranga akavharidzirwa - ekucheka veneer iyo mhando isiri pasi pekirasi II (fig.8)

Mavakirwo emapuranga ekuveza anofanirwa kuenzana, i.e. jira remapanera rinofanira kunge rakakora zvakaenzana. Mapuranga ekuveza akaputirwa kune rumwe rutivi nemucheka wakachekwa anofanirwa kune kune rumwe rutivi chidimbu chekuwedzera chevhavha yakasvibiswa, iyo yakakura yakaenzana nehupamhi hwevhavha yakachekwa pachiso chebhodhi. Nhungamiro yehuni yehuni pamashizha kubva mberi uye kumashure kwemapuranga ekuvhara inofanira kunge yakafanana, uye maererano nehurefu hwema slats - kufanana kana kutungamirirwa. Mumapuranga asina kuvharwa uye akaputirwa, anobvumirwa kuti mapepa ekunze akaunganidzirwa, akasungirirwa kubva kumucheka wevheni zvishoma 100 mm yakafara, nemamiriro ezvinhu ekuti vheji inosarudzwa maererano nehutano hwehuni uye ruvara rwayo, uye nemapuranga akavharidzirwa - maererano nekugadzirwa kwayo.
Mumapepa emashure emashure emapuranga akavharidzirwa ane hutungamiri hwehurefu hwehuni hwehuni, inobvumirwa kuenderera mberi neveneer pamwe nekureba kwemafiber.
Mumapepa ekunze emapuranga ekuveza asina kuvharwa uye akaputirwa, mukaha uri pakati pemajoini maviri anosvika 0,3 mm wakafara unobvumidzwa, pakureba isingapfuuri 250 mm pa 1 m zviso uye zvisingapfuure 3 kuseri kwemajoini. Nzvimbo yakabatanidzwa mumashizha echiso emapuranga akaputirwa inofanira kuzadzwa nekadhi yemuvara wakakodzera.
Kukanganisika kwehuni sehukasha hwemukati, mavanga, kutsemuka kusvika 200 mm pamwe chete nemapfundo ane hutano akasanganiswa kana kuti akasanganiswa zvishoma anobvumidzwa mune slats emapuranga ekuveza. Mapfundo asina kuvharwa uye maburi kubva kwavari anofanira kuzadzwa nematanda ekuisa kana kunamira iyo iyo veneer inogona kunama. Mhando dzose dzekuora uye mold mubhodhi slats hazvibvumirwi.
Mumabhodhi asina kuvharwa emhando AB uye B, pamwe chete nemapuranga akavharidzirwa emhando II, pamapepa ari kumeso, mazaruro kubva kumapfundo akadonha anofanirwa kuzadzwa nenamira kana veneer inoiswa pamusoro peglue, kugadzirisa mafambiro uye ruvara rwehuni.
Pamavheiri ekunze ekumashure, pamwe nemukati mese, mazaruro kubva kumapfundo akadonha ane dhayamita rakakura kupfuura 10 mm anofanira kuzadzwa nenamira kana vheji inoisa pamusoro peglue.
Hapafanirwe kuve nemavara kana zvisaririra zveglue panzvimbo yemahwendefa. Paunenge uchiendesa mapepa, tepi yekunamatira, iyo inobatanidza zvikamu zvemashizha akachekwa evhavha, inofanira kubviswa, uye nzvimbo dzaive pasi payo dzinofanira kucheneswa.

Kunyorova, kupfava uye kusimba

Kurutivi rwekumashure kweplateti, kuputika uye kuputika, kunokonzerwa nekuputika kana kucheka, zvinobvumirwa kusvika 300 mm, zvakanyanya 2 pcs. pa 1 m2 maplate, pamwe chete ne indentations uye zvinoonekwa kubva kune mamwe ma plates kusvika 100 mm.

Hunyoro hwemapuranga ekuveza hunofanira kuva 8 ± 2 %. Kukanganisa kunobvumidzwa kwakanyorwa mutafura. 11.

Mapuranga ekuveza anofanira kunama zvakasimba. Iyo yekupedzisira simba rekugera padanho reglue munzvimbo yakaoma haifanirwe kunge iri shoma pane10 kg/cm2. Dhata pamusoro pesimba rekupedzisira remahwendefa anopiwa mu tab.12.

Nhoroondo zvinodiwa zvechinangwa chakakosha uye bvunzo

Mabhodhi ekuveza akagadzirirwa kushandiswa mukuvaka ngoro anofanirwa kuisirwa imwe inodzivirira moto inodzivirira moto. Mapanera ekuveza anoverengerwa mum3 nemazvo 0,001 m3. Mahwendefa akagadziriswa akaverengerwa, nekuwedzera, mum2 nekururama kusvika 0,01 m2.

Mapuranga anoedzwa hunyoro, simba rekupedzisira rekugera pachikamu cheglue uye simba rekupedzisira rekubhenda.

Makirasi akanyorwa, zviyero, kushivirira uye kukosha zvinotamiswa kubva kune zvakaitika kare uye hazvifanirwe kushandiswa sechinotsiva chiziviso chechigadzirwa chazvino, mwero unoshanda, dhizaini kana kuverenga kwemutoro. Sarudzo yebhodhi uye inonamira inofanira kufunga nezvechinangwa, unyoro, kuburitswa, zvinodiwa nemoto uye nzira yekugadzirisa, uye kucheka nejecha zvinoda kudzora guruva, maturusi akakodzera uye dziviriro yemunhu.
