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、片幫等事故的發生,安全可靠,提高了礦井通風系統穩定性。選用U型鋼可縮性支架,較好解決了掘進支護的難題。

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英文字母“U”的鋼鐵。各國生產的U型鋼的斷面形狀、幾何參數以及材質等有所不同,目前中國生產的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。

U型鋼支架具有高初撐力、支護強度大、安裝簡易、不易變形等優點,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..

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.

柱腿有3種形式,一種是上部為圓弧形,下部為直線段;第二種是全部為曲線形,且只有一個曲率半徑;第三種是全部為曲線形,但有兩個曲率半徑。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工作阻力和可縮量

架間拉桿的作用是增強支架整體相對穩定性,將支架從縱向聯接起來,形成整體。


主要用于煤礦礦井巷道支護,礦井巷道二次支護,以及穿山隧道的支撐支護作用

易安裝不易變形

承受壓力大

支撐時間久

主要原材料為U型鋼,U型鋼冷彎成型後,需切割,然後用U型鋼卡蘭連接而成。

U type steel under pressure, support for a long time, and has the characteristics of easy installation is not easy deformation etc..
U type steel support than other rigid support can fit the load bearing capacity of soft surrounding rock deformation and shrinkage and stable and reliable in.
U type steel section high utilization rate in support of convenient repair in small amount to.
U3 type steel high recovery rate, reduce pitwood use, environmental benefits are obvious

Used in coal mine roadway, roadway two supporting,
And through the tunnel supporting role.
U steel, U steel cold bending forming, cutting, and then use the U type steel Karan connected to.
Under pressure, support for long time, easy to install and not easily deformed

Process: put in the waist, digging pit, column, vertical leg, on the roof beam, reinforcement → backplane (Chong Tian)
According to the midline and design studio size to find the column parameter,
Then press the waistline to column crypt depth excavation
The waist position painting in the column legs, the column on the post fossa, the column on the waist and waist consistent help
