Waa maxay sababta loo yaqaan 'pales nalka wadooyinka'?

Wadada, waxaan ku aragnaa in inta badan ulaha khafiifka ah ay yihiin kuwan inteeda badan ee iftiinka ay yihiin, taasi waa, salka sare waa dhuuban oo salka hoose waa qaro weyn, sameysa qaab isku dhafan. Ulaha nalka wadooyinka ayaa lagu qalabeeyay madaxyada laambada waddooyinka ee hogaaminaya ee awooda u dhigma awooda ama tiro ahaanta iyadoo loo eegayo shuruudaha iftiinka, markaa maxaan u soo saarnaa ulaha iftiinka ifaya?

Marka ugu horeysa, sababtuna tahay dhererka sare ee khafiifka iftiinka, haddii lagu sameeyo tuubbo dhexroor ah, iska caabbinta dabaysha ayaa ah mid daciif ah. Midda labaad, waxaan sidoo kale arki karnaa in The Clical Cornical Lion uu yahay mid qurux badan oo deeqsi ah marka loo eego muuqaalka. Saddexaad, iyadoo la adeegsanayo nabarrada iftiinka iskuxirka ah marka la barbar dhigo tuubbada dhexroor isku mid ah. Waxay badbaadin doontaa waxyaabo badan, sidaa darteed dhammaan ulaha nalka nalka iftiinka ee bannaanka u isticmaal ulaha iftiinka tijaabada ah.

Xaqiiqdii, goynta khafiifka ah ee iftiinka waxaa lagu sameeyaa iyada oo la duubay taarikada birta. Marka hore, waxaan dooranaa saxanka bir ee Q235 iyadoo loo eegayo shuruudaha dhumucda ee khafiifka wadnaha, ka dibna aan xisaabino cabirka muuqda ee ku dhaca dheellitirka sare iyo hoose ee wareega wareega, taas oo ah wareegga wareega sare iyo kuwa hoose. In this way, we can get The upper and lower sides of a trapezoid are long, and then a trapezoid is drawn on the steel plate according to the height of the street light pole, and then the steel plate is cut into a trapezoidal steel plate by a large plate cutting machine, and then the cut trapezoidal shape is cut by a light pole rolling machine. Saxanka birta ah ayaa lagu duubay qaab qunyar ah, si jirka ugu weyn ee loo yaqaan 'pat' ee lagu dhejiyo nabarrada iftiinka, ka dibna ay ku dhejinayso isku-darka tikniyoolajiyadda isku-dhafan, ka dibna alxamida alxanka, iyo dayactirka cirifka iftiinka. Qaybaha kale iyo daaweynta boostada.

Haddii aad xiisaynayso cirifka khafiifka ah ee tooska ah, ku soo dhawow inaad la xiriirto soo-saaraha khafiifka ah ee Tirtirka Tianxiang siAkhri wax dheeraad ah.
