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 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 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.
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
背衬材料是U型钢支架与围岩之间的填充材料,目的是在于使U型钢支架与围岩接触紧密,改善支架的受力状况,提高其承载能力并保持围岩的稳定性
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。
U type steel under pressure, support for a long time,Has the features of easy install ation, not easy to deformation etc。
U type steel support than other rigid support has the capacity ofcontraction and stable and reliable, To adapt to the load and deformation of soft rock
