Kodi awerenge chiwerengero cha matabwa mu kyubu ndi?

Akuyendera kuti kuwerengetsera wa mphamvu kiyubiki a mitundu yosiyanasiyana ya matabwa, ndipo muyankhe funso ili: "Kodi matabwa ambiri mu kyubu" - muyenera kuganizira tanthauzo la mawu akuti "mita kiyubiki wa matabwa," ndipo kuti limapereka yomanga msika.

mitundu matabwa ndi makulidwe awo

Matabwa amapangidwa ndi kotenga kumaliza zipika. Ndi kusakhulupirika ali ku mamita 4 mpaka 6 m'litali. M'lifupi ndi osiyana. The thinnest a kalasi ya akalowa - awiri ndi theka masentimita, namtsata shalevka bolodi amene makulidwe ndi zayamba wofanana masentimita awiri (koma zimachitika ndi 2.5, ndi 4 ndi 5 cm). More mtengo - konsekonse yomanga bolodi, amene miyeso ndi yovomerezeka zokwanira m'lifupi ndi nthawi woposa ake awiri kutalika, ndi kutalika kwa 4 (kawirikawiri 4.5) ndi mamita 6. matabwa chachikulu zimatchedwa mtanda. Pakuti mayiko nkhuni anachekedwa anagulitsa cubes, ndi kwa nyumba ndi kofunika kudziwa matabwa angati 1 kyubu.

Battens adzakhala kukhala, chifukwa chakuti mtundu wa matabwa ntchito makamaka kwa kumalizitsa ntchito ndi kuchita masamu payokha.

Choyamba, pantchitoyo adzafunika bolodi-shalevka, amene ali kangapo mtengo odulidwa ndi kufunika formwork chipangizo binder denga battens zipangizo akhakula apansi, ntchito yomanga maofesi ancillary.

M'lifupi matabwa amenewa kungakhale 10-15 cm m'litali, iwo tadulidwa mu muyezo thuu kapena atatu-mita. Kudziwa kukafika kutsogolo kwa tsogolo la maziko ndi magawo shalevki mosavuta kuwerengetsa mmene matabwa mu kyubu ndi angati kiyubiki mamita ambiri mukufuna kugula formwork lapansi. Pakuti kuwerengetsera zolondola, inu mukhoza kugwiritsa ntchito Intaneti toŵerengera kuti ali pa malo ambiri ogulitsa matabwa.

N'chifukwa chiyani tiyenera zili kiyubiki?

Ngati ufulu muyankhe funso ili: "matabwa angati kyubu pa" - mwayi udzakhala - mita kiyubiki. Tifunikanso deta kutchula. Mwachitsanzo, mmene malo akhoza atavala ndi kyubu imodzi ya makulidwe ena a matabwa?

Conventionally potanthauza m'lifupi bolodi - W, makulidwe - T, kutalika - D. The chifukwa kudzadalira pa makulidwe (T). Square chilinganizo (II) adziwika ku sukulu:

• P (m ²⁾ = wxl / T (1 mamita × 1 m / 0,02 mamita 50 mamita = ^2).

Ndiko kuti, ngati ife kutenga mita kiyubiki ya bolodi makulidwe a masentimita 2, adzaika 50 mamita ^2.

Nthawi zina muyenera kudziwa okwana kutalika (L) za mtengo mu 1 mita ^3.

Tikambirana mfundo zotsatirazi:

• D = 1 mita ³ / × T S.

Pomaliza, yankho ku funso lakuti: ". Kodi yambiri ya bolodi mu kyubu ndi (.. Mabala, billets chonse, etc.)" Ngati inu mukudziwa magawo a matabwa, chifukwa akhoza akamagwira ntchito njira:

• K = W × T × D.

Malinga ndi mfundo masamu zili izi kiyubiki wa gulu limodzi, koma musaiwale kusamutsa miyeso onse meters.

Zitsanzo za mawerengedwe a mabuku Eaves

Wotchuka kwambiri gulu edging, omwe umagwiritsidwa ntchito pa mpanda wa chipangizo, simenti, kudenga, makoma, kudenga ndi masitepe. Aliyense kukula ali ngakhale wake "dzina": dyuymovka, sorokovke, asanu, bala (yomweyo bwino, ndi za m'lifupi bolodi).

Kuwerengetsa Mwachitsanzo, mmene matabwa ambiri kyubu akhoza dyuymovka kudziwa m'lifupi. Choncho, pamene m'lifupi masentimita 10 - ndi zidutswa 66, ndipo m'lifupi mwake masentimita 15 - zidutswa 44. Wina mita kiyubiki chotha kubisa 40 mamita ^2.

Yowerengera Chitsanzo cubing dyuymovka m'lifupi asanu mita wa masentimita 15:

• 0,15 mamita × 0,025 mamita × 6 mamita = 0,0225 mamita ^3.

Ngati ndi kotheka kuwerengera buku la, mwachitsanzo, floorboards (spiked) pa dongosolo limeneri ndicho mmalo yekha ntchito m'lifupi bolodi (popanda sitadi a). Ngati blockhouse masamu (bolodi, simulating chipika), makulidwe a akusonyeza chimbuzi.
