TECHNICAL FIELD

[0001] The present application relates to the technical field of mine infrastructure, in particular to a straight-buried rigid wall connecting piece suitable for mine infrastructure engineering. BACKGROUND

[0002] Mine infrastructure engineering refers to the engineering of infrastructure construction of mines. Mine infrastructure engineering includes two ways of open mining and underground mining. Underground mining will need to build large chambers, which can be used to store materials and tools for development. When building large chambers, frames are needed to support the chambers, and wall connecting pieces are needed to fix the frames to the inner wall.

[0003] Chinese patent authorization announcement number CN206815805U, announcement date December 29, 2017, discloses a straight-buried rigid wall connecting piece suitable for high-rise and super high-rise buildings with more external windows and walls. It includes vertical rods, longitudinal horizontal rods and transverse horizontal rods. The vertical rods, longitudinal horizontal rods and transverse horizontal rods are connected and fixed at 90 degrees with each other. One end of the wall connecting piece is connected with the vertical rod through a double buckle, and the other end of the wall connecting piece extends into the beam and is fixed. The utility model completely eliminates the external wall leakage hidden trouble caused by the traditional wall connecting piece. Since the wall connecting piece is buried in the side edge of the concrete edge beam, it does not affect the external wall and the window, and does not produce water seepage points.

[0004] The prior art in the above has the following defects: when fixed, the wall connecting piece needs to be limited by anchor bars, and multiple people need to operate when installed, which is more troublesome to fix. The wall connecting piece fixes the frame composed of other parts, but the fixed position needs to be adjusted separately when fixed, and more time is needed to adjust when installed. They are all assembled separately, and are unstable when used. SUMMARY

[0010] Further, the outer diameter of the limiting ring is greater than the inner diameter of the positioning hole, and the limiting ring is pushed when moving to the position of the fixed bolt under the driving of the reinforcing rod.

[0011] Further, the outer diameter of the telescopic limiting column matches the inner diameter of the telescopic hole, and the thickness of the top plate matches the gap between the reinforcing rod and the telescopic cavity.
