National production of u-shape cross-section shape, geometric parameters and material is different, at present China''''s production of u-shape model mainly include stepping, U25, U29, U36 these four. The stepping and U25 waist position; U29, U36 belongs to the ear.

Structure Of U-Channel Steel Support for Mine Laneway Secondary Support

1.Top Beam

Top beam is circular arch, its amount depending on the cross section of roadway with different sizes, support force, transportation conditions, section 1 and section number.

2.Colum leg

There are three kinds of back leg , one kind is upside for circular arc form, for straight line at the bottom; The second is all for the curved shape, and only one radius of curvature; The third is all for the curved shape, but there are two curvature radius. Back leg in welding under the base, the base of large plate on the hard and soft;

3.Connection parts

Fitting is a support section and internode card device, can the internode connection effect, can also be connected the two compression steel joint parts, provide pre-tightening force, make the u-shape between friction, thereby ensuring that the arch has a certain resistance and certain drop-off.

4.Rod between support

Rod between support is to enhance the relative stability, the support bracket from longitudinal connection, form a whole.

5.Back-up material

Back-up material is u-shaped steel support between supports and surrounding rock filling material, the purpose is to make contact with the surrounding rock u-shape set close together, improve the stress of the support, to improve the bearing capacity and maintain the stability of surrounding rock.
