U type steel support is mainly used for mine roadway, roadway two support,
and through the tunnel supporting etc.. The use of U type steel support, help reduce roof fall accident,
safety and reliability, improves the stability of mine ventilation system.
The U shape yieldable steel ribs, a better solution to the problem of excavation and supporting.

U型鋼支架主(zhu)要(yao)用于礦井巷(xiang)道、礦井巷(xiang)道二次(ci)支護、以及穿山隧道的支撐(cheng)支護等用途(tu)。使(shi)用U型鋼支架有xing)?檔兔岸??  仁shi)故的發生,安全(quan)可靠,提高了礦井通風(feng)系統穩定(ding)性。選用U型鋼可縮性支架,較(jiao)好(hao)解決了掘進(jin)支護的難題。

U type steel frame is a cross-sectional shape like the letter "U" English steel.
U type steel all production of section shape, geometry parameters and the material is different,
the U steel model Chinese production mainly U18, U25, U29, U36 four.
The U18 and U25 belong to U29, U36 belongs to the waist position; ear positioning. U18 due to bearing capacity is low, fewer production.

U型鋼支架是一種橫截面形狀像(xiang)英文字母(mu)“U”的mu)痔8鞁型鋼的斷面形狀、幾何參數以及材質等有所不同(tong),目前中國生產的U型鋼型號(hao)主(zhu)要(yao)有U18、U25、U29、U36這四種。其(qi)中U18和U25屬腰定(ding)位(wei);U29、U36屬耳定(ding)位(wei)。U18由(you)于承載能(neng)力(li)很低,現很少生產。

U型鋼支架具有高初撐(cheng)力(li)、支護強(qiang)度大(da)、安裝簡易、不易變形等優點(dian),因此常用于制(zhi)造(zao)巷(xiang)道可縮性金(jin)屬支架,作(zuo)礦井巷(xiang)道、礦井巷(xiang)道二次(ci)支護、以及穿山隧道的支撐(cheng)支護等用途(tu)。

U type steel has a high initial support force, support strength, simple installation, not easily deformed and other advantages, therefore, commonly used in the manufacture of roadway yieldable metal, as mine, mine roadway two support, and through the tunnel supporting etc..

The connecting piece is clamped device bracket nodes and internodes,
can play the function of connection between the two,
can also be shaped steel joint part pressing connection, providing pre tightening force,
the friction force between the steel with U, so as to ensure the arch support has definite working resistance and the shrinking.

柱腿(tui)有3種形式,一種是上部為圓(yuan)弧形,下部為直線段;第二種是全(quan)部為曲(qu)線形,且只有一個曲(qu)率(lv)半(ban)徑;第三種是全(quan)部為曲(qu)線形,但(dan)有兩個曲(qu)率(lv)半(ban)徑。柱腿(tui)ren)旅婧贛械鬃 鬃拇da)小視底板軟硬而定(ding)
