(Prior art) When the cover of a manhole, etc. is hinged, a retaining ring into which the hinge fitting is inserted is provided integrally with the frame, so the direction in which the cover opens is uniquely determined. The relationship of a certain hand or side mass to a step is determined. On the other hand, during construction, the direction in which the lid is opened and closed is determined by the direction of the flow and the direction in which the vehicle is traveling, so the positional relationship with the handles and steps is not necessarily compatible. Moreover, after that,
If the location of curbs, guardrails, etc., lanes, etc. change, and the conditions on the road and ground change, the lid may come into contact with the curb or guardrail, etc., or end up in the opposite lane when the lid is opened. If you change the direction of opening the lid after the fact to avoid this, conventionally it would be necessary to remove the frame and replace it. Note that the flow direction is a problem because the hinge position may be specified in relation to the flow direction.

(Technical issue) Therefore, the purpose of this invention is to make it possible to change the opening direction of the lid without changing the frame even if there are changes in ground conditions, etc., not only before construction but also after construction. A movable hinge mechanism for underground structures in which a concave portion is formed over a certain length inside a frame body that receives a body, and a retaining ring for receiving a hinge fitting can be fixed at an appropriate position in the concave portion. Our goal is to provide the following.

(Function of the invention) The invention has a recess 3 which is long in the circumferential direction inside the frame body 2.
Since the retaining ring 7 is moved in the same direction and its position is changed via the mounting board 8 housed therein, the installation position of the retaining ring 7 and the opening direction of the lid body 1 are continuous. can be changed. Furthermore, the retaining ring 7 can be moved by loosening the bolt 9 and sliding it within the recess 3, which greatly facilitates position selection.

(Embodiment) The illustrated embodiment relates to an underground structure having a circular manhole iron cover. Flange-like convex portions 10 and 11 are provided at the inner middle and lower part of the frame body 2 that receives the cover body 1.
A recessed portion 3 consisting of the above is provided over almost the entire circumference, and the upper convex portion 10 can be used as is with the existing receiving piece 12 to prevent the inner circumferential surface of the lid taper from digging in. Only the protrusion 11 needs to be newly provided, and the engagement edges 4 and 5 with the mounting board 8, which will be described later, are integrally provided at the inner end of each protrusion 10 and 11. 13,
14 indicates a notch for inserting the mounting board 8 into the recess 3 and removing it. The mounting board 8 has a straight or gentle arc shape, and has a slit 1 between the engaging edges 4 and 5.
5 is integrated with a frame-shaped retaining ring 7 for receiving the hinge fitting 6. 17 and 18 are locking surfaces that come into contact with the inner surfaces of the engagement edges 4 and 5; 19 is a screw hole that screws into the bolt 9; 20 is a receiving hole that receives the hinge 6; 21 is a retaining protrusion of the hinge 6;
22 is a handle.

When installing, insert the retaining ring 7 into the recess 3 on the mounting board 8.
The basic installation position, for example A, is determined by considering the conditions of the installation location and the relationship with the step, and at that position, insert the bolts 9, 9 into the screw holes 19, 19 on both sides of the board. When they are screwed together and tightened, the bolt tip hits the innermost part of the recess, and the mounting board 8 is engaged with the upper and lower engaging edges 4 and 5, and is fixed in a pressed state. After that, if a curb, guardrail, lane, etc. are formed in the direction of position A, making it impossible or difficult to open the lid, or if the flow direction changes, remove the bolts 9, 9, and install the Place the substrate 8 in the recess 3 at an appropriate position, for example B.
At this point, the bolts 9, 9 are tightened and pressed again to change the mounting position of the retaining ring 7 and change the opening direction of the lid.

(Effect of the invention) Therefore, according to the present invention, the mounting board 8 provided on the retaining ring 7 can be moved along the recess 3 in the circumferential direction of the frame body and fixed by pressing at any position, so that the flow can be prevented during initial construction. It can be installed while adjusting the positional relationship with the step and the direction of travel of the car, and when changing the opening direction due to changes in ground conditions after installation, the frame 2 can be installed as usual.
The hinge position can be easily changed without any replacement work, and the direction can be changed or selected continuously, so the setting range is very wide, and the installation is easy and reliable. This has the effect of providing stable lid opening performance that does not change between the front and back.
