Roadway pressure-resistant door
The invention discloses a roadway pressure-resistant door. The periphery of a door body is of a frame structure formed by splicing a top door frame and side door frames, wherein the top door frame is transversely arranged on the top of the door body, and the side door frames are vertically arranged on the two sides of the door body. The door body is sleeved with a protective shell in the length direction of the top door frame and the side door frames. The protective shell is of a channel steel structure. Leg plates are clamped on the two sides of the top door frame and the side door frames. Gaps are reserved between a wainscot and the top door frame as well as between the wainscot and the side door frames. Long holes are transversely formed in the top of the protective shell side by side, and long holes are longitudinally formed in the two sides of the protective shell. Connection holes are formed in the positions, corresponding to the long holes of the protective shell, on the top door frame and the side door frames, and the top door frame and the side door frames are used for fixing the protective shell through bolts. By means of pre-tightening force of the bolts, direct extrusion of a roadway on the door frames is resisted, the peripheral roadway is supported, deformation amount is dispersed on the protective shell, and deformation amount of the door body is reduced. The problem that a door body is prone to deformation in a coal mine roadway is solved.
