Description

  The present invention is directed to a gutter block and an upper lid block fitting configured to perform removal and fixing work via a metal fitting having a predetermined structure that is compatible with both blocks in order to fix and remove the upper lid block to and from the gutter block. And a cover closing fixing structure.

  2. Description of the Related Art Conventionally, when an upper lid block is closed on a gutter block, the upper lid block is displaced or detached due to running vibration of a vehicle or the like. If left unchecked, there is an unexpected danger to pedestrians.

  For this purpose, both blocks are fastened and fixed via bolts, fixtures and the like (for example, see Patent Documents 1 and 2).

  However, even if both blocks are tightened and fixed with bolts, there may be cases where the connection position with bolts is not limited to one place but may be multiple places, or the fixing position needs to be changed according to the installation situation of the top lid block Occurs.

  In such a case, if the position of the fixing device is fixed in advance, it is impossible to change the fixing position corresponding to the situation, and it is not possible to completely close and fix the upper cover block to the gutter block, causing a road accident. It was.

  The present invention has been made in view of such circumstances, and in order to fix or remove an upper lid block to or from a gutter block, a removal and fixing operation can be performed via a metal fitting having a predetermined structure that is compatible with both blocks. The present invention provides a lid-closed fixing structure using metal fittings for the side groove block and the upper lid block.

  In order to solve the above-mentioned conventional problems, in the present invention, a gutter fitting for lid connection is buried at the top end of the gutter block, and the upper surface thereof is exposed flush with the block surface, and is provided on the bottom surface of the side edge of the upper lid block. An upper cover metal fitting made of a flat press-fit body is buried and the surface is exposed flush with the block surface, and the exposed surface of the side groove metal fitting and the exposed surface of the upper lid metal fitting with the upper lid block closed with the side groove block closed. And the upper and lower abutment joining state, and the side groove metal fitting cuts at least a portion of the female screw cylindrical body at least substantially above the cross-sectional center line along the longitudinal direction of the cylindrical body. Is used as a connecting bolt sliding groove portion, and a substantially semi-circular male screw sliding body slidable while being in contact with the female screw without being screwed into the female screw cylinder is housed in the female screw cylindrical body so as to be adjustable in position. Connecting bolts are erected on the top of the moving body At the same time, the upper cover fitting is provided with a connecting bolt insertion hole in the flat pressure contact body, and when the upper cover block is closed in the side groove block, a fastening nut is screwed to the connection bolt protruding upward from the connection bolt insertion hole through the connection bolt insertion hole. Thus, there is provided a closed-close fixing structure of the side-groove block and the upper-cover block, wherein the upper-groove bracket is joined to the side-groove bracket by fastening.

  Further, the lid fixing structure according to the present invention is characterized in that a gutter anchor is vertically provided on the gutter metal fitting and a lid anchor is provided on the upper lid metal fitting.

  In the lid fixing structure according to the present invention, the connection bolts projecting upward from the connection bolt insertion holes and the fastening nuts screwed to the connection bolts are all unfastened from the upper surface water holes provided in the upper cover block. It is characterized by being disposed at a position facing the upper surface water hole so that operation is possible.

  According to the first aspect of the present invention, a gutter fitting for lid connection is buried at the top end of the gutter block, the upper surface thereof is exposed flush with the block surface, and a flat plate-shaped pressure contact is made on the bottom surface of the side edge of the upper cover block. An upper cover bracket consisting of a body is buried and its surface is exposed flush with the block surface, and with the upper cover block closed, the exposed surface of the gutter bracket and the exposed surface of the upper cover bracket are held up and down. The side groove fitting is configured to cut at least a portion of the female screw cylindrical body at least substantially above the cross-sectional center line in the longitudinal direction of the cylindrical body, and to connect the longitudinally cut portion to the connecting bolt sliding groove. A substantially semi-circular male screw sliding body that is slidable while being in contact with the female screw without being screwed into the female screw cylindrical body is housed in the female screw cylinder so that the position can be adjusted, and a connection bolt is provided on the upper surface of the male screw sliding body. The flat shape of the upper cover bracket When it is desired to change the position of the connection bolt protruding upward from the connection bolt insertion hole provided in the press-contact body, that is, to change the joint fixing position of the side groove block and the upper lid block by the connection bolt, the connection bolt is set up substantially in a half. The position can be changed while sliding the arcuate male screw slide along the connecting bolt sliding groove of the female screw cylinder.

  In addition, the more the pressure-contact member of the upper cover metal fitting of the upper cover block is pressed against the side groove metal fitting via the connection bolt and the tightening nut, the more approximately the semicircular arc-shaped male screw slide is in the connection bolt slide groove of the female screw cylinder. Thus, a tight contact state may be generated via the mutual screw grooves, and the risk of inadvertent displacement in the connecting bolt sliding groove portion can be prevented.

  In addition, when the position of the connecting bolt is changed, the connecting bolt and the tightening nut are loosened so that the substantially semi-circular male screw sliding body can be easily slid in the connecting bolt sliding groove. There is an effect that becomes possible.

  According to the second aspect of the present invention, the side groove anchors are provided vertically on the side groove metal fittings, and the lid anchors are provided on the upper lid metal fittings, so that each metal fitting is securely embedded in each block. There is an effect that can be fixed.

  According to the third aspect of the present invention, the connection bolt projecting upward from the connection bolt insertion hole and the fastening nut screwed into the connection bolt is released from the upper surface water hole provided in the upper lid block. The upper lid block is provided with an operation of screwing and tightening a tightening nut to a connecting bolt projecting upward from the connecting bolt insertion hole through the connecting bolt insertion hole by arranging the upper cover block at a position opposed to the upper surface water hole so that operation is possible. Since it can be performed through a jig such as a wrench inserted from the upper water passage hole, there is an effect that the fixing work of both blocks can be easily and reliably performed.
