蓋を提供することを目的とする。In the above-mentioned conventional cover for an underground structure, a pivot pin of a seat is inserted into a support groove of a mounting space on the inner periphery of a receiving frame, and a connecting space of the receiving seat is connected to the connecting groove. Since the hinge is locked to the locking space of the seat through the space, when the lid body is turned over or turned to open and close the opening of the receiving frame, the hinge will move up and down. With the movement, the seat itself moves up and down or rotates, the pivot pin comes out of the support groove, the seat comes off the mounting space, and the hinge passes from the locking space of the seat. There is a possibility that the member may move toward the part and separate from the seat. The present invention has been developed in view of the above, and during opening and closing work of the lid body, the seat is detached from the mounting space,
An object of the present invention is to provide a lid for an underground structure that allows a hinge body to be safely and easily detached and opened and closed without a hinge being detached from a seat.

That is, in the lid 1 for an underground structure according to the present invention, as shown in FIGS. 11 to 14, the hinge 15 is swingable with respect to the lid body 3. In addition, the hinge 15 is rotatable with respect to the receiving seat 12 and is movable in the locking space 23 and the communication space 24. In addition, the hinge 15 can be tilted while the stopper portion 20 is locked on the tilt locking surface 26. Meanwhile, seat 1
Reference numeral 2 designates a bearing from a substantially horizontal state in which the base end portion 12a is locked to the ceiling of the mounting space 5 with the shaft piece 10 fixed to the bearing piece 7 and the bearing seat 9 provided on the receiving frame 2 as a fulcrum. The seat 12 is rotatable to a state of being slightly inclined from the vertical position, which is locked to the edge of the inclined fitting portion 4. Therefore, the opening and closing operation of the lid body 3 can be performed extremely smoothly. In addition, since there is no need to support the lid body 3 in an unstable state during the work of mounting the seat 12 and the like, the work can be performed not only easily but also safely.

可能となる。In summary, the present invention comprises a lid body provided with a hinge that oscillates and a receiving frame for closing the opening so that the opening can be opened and closed. form forms a mounting hollow portion to release the interior, and the bearing piece on the left and right sides of the mounting hollow portion having a bearing hole opened in the horizontal direction, a bearing seat having a fastening hole opened vertically or horizontally Are opposed to the center of the receiving frame, and a passing space portion through which a stopper portion provided at the lower end of the hinge is able to pass, and a locking portion where the stopper portion is not passable and locks the hinge. After passing a stopper having a communicating cavity communicating with the passing cavity and the locking cavity, a stopper is inserted into the passing cavity, and a shaft pin is passed through the passing cavity. Inserting the distal end of the shaft pin into the bearing hole and attaching the base end of the shaft pin to the fastening hole. As the hinge pin is rotatably provided on the receiving frame, the shaft pin does not come off from the receiving frame and the seat does not come off, and the hinge pin crosses the passage empty space of the seat, so the hinge It does not fall out of the seat. In addition, the seat and the hinge can be mounted while the lid body is placed on the ground surface, and there is no need for an operator to support the heavy lid body, making the operation extremely easy and safe. become. In addition, since the lid for underground structures according to the present invention has a plurality of mounting cavities formed in the receiving frame and the receiving seat is detachable,
Even after the installation of the receiving frame, the direction of the lid main body can be easily changed by changing the mounting position of the receiving seat.
Therefore, in the case where a curb or a tree is present in the turning direction or the reversing direction of the lid body and becomes an obstacle, the obstacle can be solved only by changing the position of the seat and changing the release fulcrum position of the lid body. Alternatively, even when the design of the lid body does not match the road surface, the position of the seat can be changed to change the design state of the lid body. Moreover, in such a case, the attachment / detachment work of the lid body can be performed without straddling the receiving frame, so that it is safe. Furthermore, since the seat is rotatable in the vertical direction with respect to the receiving frame , when the lid body is released, the amount of protrusion of the seat into the receiving frame is reduced, so that the effective inner diameter of the receiving frame is increased. Not only is it easy and safe for workers to enter and exit, but also large maintenance and inspection equipment can be brought in and out of the manhole.
