Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a road crossing groove block, which is suitable for running pressure of heavy objects such as automobiles. It was developed to make the structure before and after the road crossing ditch block difficult to cause subsidence. It is a thing.

[0002]

[Prior art]

  A conventional road crossing groove block has a step groove on the upper surface of which a grating is placed. It was a letter block.

[0003]

[Problems to be solved by the device]

  This will cause the ground to sink before and after the road crossing groove block, Only the hooks protrude above the road surface, deteriorating the riding comfort of the car and, in some cases, the groove block. There was a problem that even the damage of Ku was brought.

[0004]

[Means for Solving the Problems]

  The present invention was developed for the purpose of solving the above-mentioned drawbacks. In a U-shaped block having a step groove for mounting a lid such as a permeable water-permeable lid, It is characterized in that the step 2 of the subsidence prevention plate 10 is formed in the middle part.

[0005]   Road crossing gutter blocks may have rectangular sides but roads run from the center to the sides. Since there is a flow gradient, from the center of the road so that it is possible to meet at the center The slope of the abutting surface 3 with respect to the bottom surface 4 should be deviated from 90 ° so that it almost matches the slope to the side. It is convenient to use a graded road crossing groove block.

[0006]

[Action]

  The mounting step 2 is formed in the middle portion of the side wall 5, and the flat ground subsidence prevention plate 10 is installed on this. By embedding in the road surface, the ground before and after the road crossing groove block is strengthened, The flatness between the upper surface of the road crossing groove block and the road surface is maintained.

[0007]   In this groove block, hit the road so that it almost matches the slope from the center to the side of the road. By tilting the slope of the vertical surface 3 with respect to the bottom surface 4 from 90 °, There is no gap in the groove block abutting part, so it is necessary to cast joint concrete on site. Disappear.

【Example】

  FIG. 1 is a road cross section showing a state in which a subsidence prevention plate is placed on a road crossing groove block of the present invention. It is a figure. FIG. 2 is a side view of only the road crossing groove block.   As can be seen in these figures, this road crossing gutter block 1 has a grate on the upper surface. The step groove 6 on which the ring 11 and a normal concrete lid are placed at the upper and opposite positions of both side walls. It is a U-shaped block having. A subsidence prevention plate 10 is provided on the outer middle portion of the block side wall 5. Forming a mounting step 2 on which one edge of In this example, the mounting position of the mounting stage 2 is a block. It should be installed in the middle of the area and slightly below the thickness of the subsidence prevention plate 10 from above. There is. This mounting step 2 has a connecting pin insertion hole, for example, a middle diameter is large and both ends are The tapered connecting pin 7 is inserted to prevent the pin from sinking. One edge of the stop plate 10 is placed, and the connecting pin 7 is inserted into the pin hole on the back surface of the sinking prevention plate 10. It is designed so that it cannot be removed once it is inserted. This subsidence prevention plate 10 has a pavement material on its upper surface. Covered and invisible.

[0009]   The connection between adjacent road crossing groove blocks 1 is, for example, a joint as shown in FIGS. The metal fitting 8 is used. The structure of the joint metal fitting 8 is composed of the anchor bars 8a embedded in the block. For the integral connecting bolt hole 8b, connect the triangular connecting The rate 8c is screwed by the connecting bolt 8d.

[0010]   Conventionally, this kind of road crossing groove block has been constructed as shown in FIG. The butting surface 13 of is perpendicular to the bottom surface, that is, the inclination to the bottom surface 14 of the block is 90 °. Met. Therefore, in the central part of the road, there is a wide groove in the upper part, so there is a median strip. There is no problem if it is used, but in-situ concrete 15 I needed to.   FIG. 5 shows an example of the present invention. It is clear from the comparison with FIG. 6 showing the conventional block. The bottom surface 4 of the abutting surface 3 so as to almost match the slope from the center to the side of the road. The gradient for is deviated by W from the dashed-dotted line of 90 °. With this, the construction Can be easily completed just by installing the blocks while connecting them with the above fittings Became.

[0011]

[Effect of device]

  The road crossing groove block of the present invention has the above-mentioned structure, so that the heavy load such as automobiles It became difficult for the land subsidence to occur even under the running pressure of. Road crossing ditch block The ground subsides before and after, and only the road crossing groove block protrudes from the road surface The deterioration of the ride quality of the car is resolved, and further damage to the groove block is prevented. The effect was also obtained. In addition, the construction is easy.
