U型钢支架主要用于矿井巷道、矿井巷道二次支护、以及穿山隧道的支撑支护等用途。使用U型钢支架有效降低冒顶、片帮等事故的发生,安全可靠,提高了矿井通风系统稳定性。选用U型钢可缩性支架,较好解决了掘进支护的难题。
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型钢支架是一种横截面形状像英文字母“U”的钢铁。各国生产的U型钢的断面形状、几何参数以及材质等有所不同,目前中国生产的U型钢型号主要有U18、U25、U29、U36这四种。其中U18和U25属腰定位;U29、U36属耳定位。U18由于承载能力很低,现很少生产。
U型钢支架具有高初撑力、支护强度大、安装简易、不易变形等优点,因此常用于制造巷道可缩性金属支架,作矿井巷道、矿井巷道二次支护、以及穿山隧道的支撑支护等用途。
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

结构组成
柱腿有3种形式,一种是上部为圆弧形,下部为直线段;第二种是全部为曲线形,且只有一个曲率半径;第三种是全部为曲线形,但有两个曲率半径。柱腿下面焊有底座,底座的大小视底板软硬而定。
顶梁为圆弧拱形,其数量视巷道断面大小、支架受力、运输条件的不同有1节和多节之分。
连接件是支架节与节间的卡紧装置,可以起节间的连接作用,还可以将连接的两节型钢接头部分压紧,提供预紧力,使U型钢之间具有摩擦力,从而保证拱形支架具有一定的工作阻力和一定的可缩量。
架间拉杆的作用是增强支架整体相对稳定性,将支架从纵向联接起来,形成整体。
产品特点
U型钢支架承受压力大,支撑时间久,
具有易安装不易变形等特点。
U type steel under pressure, support for a long time,
Has the features of easy installation, not easy to deformation etc
U型钢支架较其他刚性支架具有可缩性和稳定可靠的
承载能力,适应松软围岩的载荷和变形。
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型钢支架断面利用率高
支架支回方便、维修量小。
U type steel section high utilization rate
Support to repair convenient, small amount of
U型钢支架回收复用率高,
