Japanese Utility Model Publication No. 06-047926

  As shown in FIG. 5, the conventional curb and drainage unit (steel drainage and autoguard unit) 100 is laid between the road surface 102 of the road bridge 101 and the balustrade 103, that is, on the road shoulder 104 as described above. It is installed on the mortar 105. The curb and drainage groove unit 100 includes a water channel portion 106 and a cover portion (auto guard portion) 107. The water channel portion 106 is covered with the cover portion 107 from above, and is configured in a substantially cylindrical shape. Is. The water channel portion 106 is fixed to the road surface 102, the balustrade 103, and the floor mortar 105 in a stationary state by, for example, a buried anchor 108 or the like.

  A pair of receiving portions (L-shaped steel) 106a is formed in the water channel portion 106, and a water channel portion side insertion hole (insertion ring) 106b for inserting a pin to be described later is formed. On the other hand, the cover portion 107 is formed with a water collection surface 107a and an inclined surface portion (tire support portion) 107b formed integrally with the water collection surface 107a. Further, the cover portion 107 is connected to the water channel portion 106 with the pair of receiving portions. A cover part side insertion hole (insertion ring) 107c is formed so as to communicate with the water channel side insertion hole 106b when covered with (L-shaped steel) 106a. The cover portion side insertion hole 107c is fixed to a reinforcing plate 107d formed on the back surface of the cover portion 107 and extending in the vertical direction by welding or the like.

  When the cover portion 107 is placed on the water channel portion 106 and the both insertion holes 106b and 107c communicate with each other, rubber fixing pins (pins) 109 are inserted into the both insertion holes 106b and 107c. As a result, the cover 107 is fixed to the water channel 106. The water collection surface 107 a has a drain hole 110 that opens to the water channel portion 106, and rainwater that has fallen on the road surface 102 flows into the water channel portion 106 through the drain hole 110. Further, the inclined surface portion 107b corrects the direction of a tire (not shown) riding on the inclined surface portion 107b toward the road surface 102 (pushes the tire back toward the road surface 102).

  By the way, the road bridge 101 on which the curb stone / drainage unit 100 constructed as described above is installed generally has a long overall length. Therefore, in order to cope with this, the curb and drainage groove unit 100 is connected in the length direction thereof, and the drainage groove (the water channel portion 106) continues to the sewer (not shown) provided outside the bridge. Functioning as a groove). At this time, depending on the overall length of the road bridge 101, it is necessary to install a considerable number of curbstone / drainage unit 100.

However, in the above case, the following problems occur. That is, conventionally, the cover portion 107 is placed on the water channel portion 106 and fixed by the fixing pin 109. For example, for one reason (accident etc.), one end portion of the cover portion 107 as described above. In some cases, car tires may get on.
At this time, if the downward force due to the weight of the tire or the vehicle, the so-called external force exceeds the coupling force between the water channel portion 106 and the cover portion 107 in the fixing pin 109, the other end of the cover portion 107 is caused by the external force. As a result, the fixing pin 109 is removed from the water channel side insertion hole 106b, and sometimes the entire cover 107 is released from the water channel 106 and jumps up and jumps out to the road surface 102 or the like.

In order to cope with this, it is only necessary to securely fix the cover portion 107 to the water channel portion 106 with a chain (not shown) or the like. The degree of freedom is greatly limited, and the water channel portion 106 and the cover portion 107 cannot be completely removed.
The present invention has been made in view of the above circumstances. Therefore, the object of the present invention is to provide a curbstone / drainage unit having a cover portion that is difficult to be removed by an external force due to tire contact or the like and is easily removed by human operation. Is to provide.

  In order to achieve the above object, the curbstone / drainage unit of the present invention comprises a water channel portion and a cover portion detachably attached to the water channel portion so as to close the open portion of the water channel portion from above. An engaged portion is fixed to the water channel portion, and when the cover portion is moved upward by a predetermined distance, the cover portion engages with the engaged portion and moves further. The to-be-engaged part to be regulated is fixed, and the engagement with the engaged part is released when the engaging part is moved in a direction different from the upward direction in the engaged state. It is comprised so that it may be comprised (Invention of Claim 1).

  According to this configuration, first, in the case of cleaning work, the cover part is moved upward by a predetermined distance, and when the engaging part is engaged with the engaged part, it is only moved in a direction different from the above direction. Since the cover part can be easily removed from the water channel part by operation, the removal work of the cover part by human operation can be made very simple. Furthermore, even if an external force from a tire or the like is applied to one end portion of the cover portion and the other end portion is lifted, if the cover portion moves upward by a predetermined distance, the engaging portion of the cover portion is engaged. Is engaged and stopped, and further movement is restricted, so that it is possible to make it difficult for the cover portion to come off by such an external force.

In the above case, the cover portion may be configured to have an inclined surface portion inclined downward with respect to the installation surface (invention of claim 2).
According to this configuration, even if the tire rides on the curbstone / drainage unit, the tire direction is immediately corrected to the road surface side, so that it is difficult to cause an accident or the like. Furthermore, rainwater can be efficiently guided to the water channel.

Further, in the above case, a plurality of fitting pins are formed in the water channel portion, and a fitting hole for fixing the cover portion to the water channel portion by engaging with the fitting pin is formed in the cover portion. (Invention of claim 3).
According to this configuration, first, the cover portion can be further prevented from coming off from the water channel portion by the fitting pin and the fitting hole.

  In the above case, the engaged portion protrudes toward the cover portion, the engaging portion protrudes toward the water channel portion, the engaged portion includes a horizontal surface portion, and the engaging portion is A vertical surface portion that is positioned below the horizontal surface portion with the cover portion covered with the water channel portion and that engages perpendicularly to the horizontal surface portion when the cover portion is moved upward by a predetermined distance. And the portion of the vertical surface portion that engages with the horizontal surface portion may be formed so as to be inclined obliquely downward with respect to the horizontal surface portion (invention of claim 4).

  According to this configuration, the horizontal plane portion and the vertical plane portion are engagements (an engagement close to a so-called line contact) between the base end portion of the vertical plane portion and the tip end portion of the horizontal plane portion. Therefore, when the cover part 4 is moved in the inclination direction after the engagement, it suffices if the cover part 4 is moved along the inclination direction of the vertical surface part, so that the inclination serves as a guide and the cover part 4 is further easily removed.

  As described above, according to the curb and drainage groove unit of the present invention, the cover part has an excellent effect that it is difficult to be removed by external force due to tire contact or the like with respect to the water channel part and is easily removed by human operation. Obtainable.

An embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the curb / drainage unit 1 is continuously installed over the entire length of the road bridge, for example, on the shoulder 2 of a road bridge (not shown, for example, a general bridge over a river). It is composed of a long water channel portion 3 having an opening 3a in the upward direction, and a cover portion 4 that is detachably attached to the water channel portion 3 so as to close the opening 3a. . The road shoulder 2 is located between the road surface 5 and the balustrade 6, and the curb and drainage groove unit 1 is laid on the installation surface 7 between the road surface 5 and the balustrade 6. 8 is installed.

  The water channel 3 of the curb and drainage groove unit 1 includes a drainage surface 3b through which drainage such as rainwater flows, a first mounting surface 3c that is positioned on the balustrade 6 side of the drainage surface 3b and extends upward, and a road surface 5 side. And a second mounting surface 3d that extends upward and is shorter than the first mounting surface 3c. The water channel portion 3 is installed side by side in the length direction of the road bridge, and thus functions as a drainage groove continuing to a sewer (not shown) provided outside the bridge. In the curb / drainage unit 1, the water channel portion 3 integrates the buried anchor 9 formed on the first mounting surface 3 c with the balustrade 6, and integrates the back surface of the drainage surface 3 b with the mortar 8. By fixing it, it is fixed in a stationary state.

  On the first mounting surface 3c, as shown in FIG. 2 which shows a perspective perspective view of the curb / drainage groove unit 1 alone with the cover part 4 slightly removed from the water channel part 3, the length of the curb / drainage groove unit 1 is long. A plurality of first fitting pins 10 are provided along the length direction, and a plurality of second fitting pins 11 are provided on the second mounting surface 3d. Further, an engaged portion protruding toward the road surface 5 side (left side in FIG. 1) is provided at a substantially central portion (a lower portion than the first fitting pin 10) in the height direction of the first mounting surface 3c. A plurality of 12 are fixed by welding. The engaged portion 12 is composed of a vertical plane portion 12a (hereinafter referred to as a rib 12a) and a reinforcing surface portion 12b formed integrally with the rib 12a, so that its cross section is L-shaped. Is formed.

  The water channel portion 3 is covered with the cover portion 4 so as to close the opening 3 a of the water channel portion 3. The cover portion 4 is formed so as to be substantially flush with the road surface 5 and a rainwater guide surface portion 4a formed integrally with the rainwater guide surface portion 4a and inclined downward with respect to the installation surface 7 It is comprised from the surface part 4b. As shown in FIG. 2, a plurality of drainage holes 13 having a horizontally long shape for allowing rainwater or the like from the road surface 5 to flow into the drainage surface 3 b of the waterway part 3 are formed in the rainwater guide surface part 4 a. Further, the road surface side end portion of the rainwater guiding surface portion 4a is bent downward to form a bent surface portion 4c, and a second fitting that fits the second fitting pin 11 is formed on the bent surface portion 4c. A plurality of fitting holes 14 are formed, and the second fitting pin is fitted into the fitting hole 14, so that the rainwater guiding surface portion 4 a is in an immobile state.

  On the other hand, the inclined surface portion 4b is formed so as to cover the space between the drain hole 13 and the balustrade 6 without a gap. An extended fitting surface portion 4d extending downward is fixed to the back surface of the inclined surface portion 4b by, for example, welding. As shown in FIG. 2, the extended engagement surface portion 4c is formed with a plurality of first fitting holes 15 for fitting with the first fitting pins 10 provided on the first mounting surface 3c. By fitting the first fitting pin 10 into the first fitting hole 15, the inclined surface portion 4 b is in an immobile state. As described above, the first and second fitting pins 10 and 11, and the first and second fitting holes 15 and 14 fitted with the first and second fitting pins 10 and 11, The cover part 4 is detachably attached to the water channel part 3.

  Further, the lower surface of the inclined surface portion 4b in the height direction (the lower portion than the rib 12a) is formed integrally with the rear surface reinforcing surface portion 16a and the rear surface reinforcing surface portion 16a and engages with the rib 12a. The engaging portion 16 composed of the fin 16b which is a vertical surface portion is fixed by welding. As shown in FIG. 2, the fins 16b are respectively formed at positions corresponding to the ribs 12a in the longitudinal direction of the curbstone / drainage unit 1, and the fins 16b are obliquely below the ribs 12a ( In FIG. 1, it is formed so as to incline in the lower right direction).

  Now, in the curb / drainage unit 1 configured in this way, for example, rain water from the road surface 5 of the road bridge at the time of rain (the road surface 5 is generally formed so as to be inclined downward toward both ends in the width direction). Therefore, the rainwater on the road surface 5 naturally flows in the direction toward the shoulder 2) reaches the rainwater guide surface portion 4a, and this rainwater flows into the drainage surface 3b of the water channel portion 3 from the drain hole 13 of the rainwater guide surface portion 4a. . At this time, the curb and drainage groove unit 1 is continuously installed over the entire length of the road bridge and has a drainage groove (having a drainage function) as described above. The rainwater that flows in flows through the continuous drainage surface 3b, that is, the drainage groove, and is eventually guided to the sewer.

  By the way, the rainwater flowing into the drainage surface 3b flows through the road surface 5 and then into the drainage surface 3b. Therefore, various contaminants such as asphalt dust, tire wear dust, tree branches and vehicles Garbage thrown away from is mixed. For this reason, if the drainage surface 3b is left for a long period of time, these contaminants are clogged and sometimes the drainage function of the road surface 5 cannot be performed, and the road surface 5 is flooded when the amount of rainfall is large. Therefore, it is necessary to periodically remove the cover part 4 and clean the drainage surface 3b (in the water channel part 3).

  Here, in the curb stone / drainage unit 1 in the present embodiment, the cover portion 4 is fitted into the first and second fitting holes 15 and 14 with respect to the water channel portion 3. Since the cover pins 4 are attached by the mating pins 10 and 11, when the cover portion 4 is artificially removed for the cleaning work, the cover portion 4 is moved upward, as shown in FIG. Remove the holes 14 and 15 from the respective fitting pins 10 and 11 (At this time, since the fitting pins 10 and 11 and the fitting holes 14 and 15 are only fitted, the cover portion 4 moves upward. If it is lifted, it can be easily detached from the water channel part 3).

  When the proximal end portion 16c of the fin 16b of the cover portion 4 is engaged with the distal end portion 12c of the rib 12a, as shown in FIG. 4, the direction different from the upward direction, that is, the inclination direction of the fin 16b (in this embodiment) In this case, since the engagement between the fins 16b and the ribs 12a is easily released by moving in the upper left direction in FIG. 1, the cover part 4 can be removed from the water channel part 3 by a very simple operation.

  Further, by inclining the fins 16b obliquely downward, mutual engagement becomes engagement between the base end portion 16c of the fin 16b and the tip end portion 12c of the rib 12a (engagement close to so-called line contact). Therefore, when the cover part 4 is moved in the tilt direction after the engagement (in order to remove it), the tilt serves as a guide, and there is no weight due to the friction of the engagement. The cover part 4 can be slightly rotated around the center (the engagement is close to a line contact, and thus can be the center of rotation), and the cover part 4 can move relatively in the direction of movement (accurately in the inclined direction). There is no need to move it, and it is only necessary to move it roughly diagonally to the left.), It is easier to remove the cover 4.

  Further, since the cover portion 4 is not provided with a chain for fixing the cover portion 4 or the like, the cover portion 4 can be completely removed from the water channel portion 3 and the degree of freedom in moving the cover portion 4 is increased. Since it becomes favorable, not only can the water channel portion 3 be reliably cleaned, but also the cover portion 4 can be cleaned. Furthermore, when the cover part 4 is obstructive in the cleaning work, the cover part 4 can be temporarily collected in a place different from the cleaning work part.

  On the other hand, if the tire approaches the road shoulder 2 due to a mistake in driving operation or the like and the tire rides on one end of the cover part 4, an external force is applied to this part in the downward direction. In the curb and drainage groove unit 1 in this embodiment, the cover portion 4 is provided with the fins 16b and the water channel portion as described above. 3 is provided with a rib 12a. For this reason, even if the other end of the cover portion 4 tries to float upward, the fin 16b (the base end portion 16c depends on the direction of the external force when it moves upward by a predetermined distance). And the entire fin 16) engage with the rib 12 a, and further upward movement is restricted. Therefore, the cover part 4 is difficult to come off due to an external force due to tire contact or the like, thereby preventing a situation in which the cover part 4 jumps out on the road surface 5.

  Moreover, in the cover part 4, since the inclined surface part 4b inclines below with respect to the installation surface 7, even if a tire rides on this inclined surface part 4b, it will immediately push the direction of this tire back to the road surface 5 side. In order to correct (having a guide function), it is possible to make it difficult to cause an accident such as a collision of the vehicle with the railing. Furthermore, rainwater can be efficiently guided to the drain hole 13.

In this embodiment, the curb / drainage unit 1 is applied to the shoulder 2 of the road bridge. However, the present invention is not limited to this, and may be applied to, for example, an ordinary general road or a median strip. .
Moreover, although the shape of the fin 16b was formed so as to be inclined obliquely downward with respect to the rib 12a, it is not limited thereto, and may be parallel to the rib 12a, for example. Furthermore, a claw like a hooking part may be formed at the end of the rib, and a convex part hooked with the claw may be formed on the fin. In this case, the mutual engaging force is strengthened, and the cover part 4 is further less likely to be detached from the water channel part 3 by an external force.

  Alternatively, the rainwater guiding surface portion 4a may be eliminated, the entire surface may be configured as an inclined surface portion, and the drain hole 13 may be formed in a lower portion of the inclined surface portion.
