Bolt connection plate for connecting tunnel inverted arch steel frame with arch angle steel frame

The utility model discloses a bolt connection plate for connecting a tunnel inverted arch steel frame with an arch angle steel frame and solves the problems in the tunnel construction process that when the inverted arch steel frame is connected with the arch angle steel frame, because of the unreasonable connection plate structure, the bolt holes on the connecting plate are difficult to align at, the connection is improper and the potential safety hazard exists. The bolt connecting plate comprises a bolt connecting plate A and a bolt connecting plate B, wherein four to ten bolt holes are drilled on the bolt connecting plate A; on the bolt connecting plate B, bolt holes are drilled on the positions corresponding to the bolt holes on the bolt connecting plate A; and two to four adjustable bolt holes are respectively drilled at two sides of the bolt holes along the length direction on the bolt connecting plate B by taking the bolt holes opposite to the bolt holes on the bolt connecting plate A, on the bolt connecting plate B as centers. To some extent, the bolt connection plate in the utility model can solve the problems that the bolt holes on the bolt connecting plate cannot be aligned at and the connection is improper. The connection is more stable and the potential safety hazards are reduced by using the dynamic adjustable connection method and the method for arranging the bolt slot or changing the arranged positions of the bolt holes.
