點(diǎn)擊數:
U型鋼支架主要用于礦井巷道、礦井巷道二次支護、以及穿山隧道的支撐支護等用途。使用U型鋼支架有效降低冒頂、片幫等事故的發(fā)生,安全可靠,提高了礦井通風(fēng)系統穩定性。選用U型鋼可縮性支架,較好解決了掘進(jìn)支護的難題。
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型鋼支架是一種橫截面形狀像英文字母“U”的鋼鐵。各國生產(chǎn)的U型鋼的斷面形狀、幾何參數以及材質(zhì)等有所不同,目前中國生產(chǎn)的U型鋼型號主要有U18、U25、U29、U36這四種。其中U18和U25屬腰定位;U29、U36屬耳定位。U18由于承載能力很低,現很少生產(chǎn)。
U型鋼支架具有高初撐力、支護強度大、安裝簡(jiǎn)易、不易變形等優(yōu)點(diǎn),因此常用于制造巷道可縮性金屬支架,作礦井巷道、礦井巷道二次支護、以及穿山隧道的支撐支護等用途。
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

結構組成
柱腿有3種形式,一種是上部為圓弧形,下部為直線(xiàn)段;第二種是全部為曲線(xiàn)形,且只有一個(gè)曲率半徑;第三種是全部為曲線(xiàn)形,但有兩個(gè)曲率半徑。柱腿下面焊有底座,底座的大小視底板軟硬而定。
頂梁為圓弧拱形,其數量視巷道斷面大小、支架受力、運輸條件的不同有1節和多節之分。
連接件是支架節與節間的卡緊裝置,可以起節間的連接作用,還可以將連接的兩節型鋼接頭部分壓緊,提供預緊力,使U型鋼之間具有摩擦力,從而保證拱形支架具有一定的工作阻力和一定的可縮量。
架間拉桿的作用是增強支架整體相對穩定性,將支架從縱向聯(lián)接起來(lái),形成整體。
產(chǎn)品特點(diǎn)
U型鋼支架承受壓力大,支撐時(shí)間久,
具有易安裝不易變形等特點(diǎn)。
U type steel under pressure, support for a long time,
Has the features of easy installation, not easy to deformation etc
U型鋼支架較其他剛性支架具有可縮性和穩定可靠的
承載能力,適應松軟圍巖的載荷和變形。
U type steel support than other rigid support has the capacity of contraction and stable and reliable,
To adapt to the load and deformation of soft rock
U型鋼支架斷面利用率高
支架支回方便、維修量小。
U type steel section high utilization rate
Support to repair convenient, small amount of
U型鋼支架回收復用率高,
減少坑木使用,環(huán)保效益十分明顯
U3 type steel high recovery rate,
Reduce pitwood use, environmental benefits are obvious
