Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter structure for installation on a ground mainly using spik shoes such as a baseball field, an athletic field, and a tennis court.

[0002]

[Prior art]

 In various ball playgrounds and athletic stadiums, concrete gutters are formed at the edge of the ground for drainage. Conventionally, the gutters have been covered with concrete, steel grating, wooden lids, or the like. However, riding spike shoes on these could cause the spike pins to slip, causing competitors to fall, and they were often subjected to strong impact at their feet.

For this reason, since the gutter portion is a dangerous place, it is conceivable to put an elastic rubber groove lid on the gutter member made of concrete and cover the concave portion of the gutter member with a lid. Have been published (Japanese Utility Model Publication 60-20717). This is one in which a rubber groove cover is placed and bridged over a pair of side walls of the gutter member to cover the recess.

[0004]

[Problems to be solved by the device]

 By the way, the above-mentioned gutter member is installed on the periphery of the ground or the like. Therefore, it is often the case that there is a retaining wall on one edge of the gutter member and embankment on the other edge. When installing the rubber groove lid, the groove lid is simply placed on the gutter member. At this time, one side of the groove cover is applied to the retaining wall side, and the other side of the groove cover is applied to the embankment side to position the groove cover. However, once the gutter lid was installed, the edge of the embankment collapsed and the surface of a part of the gutter lid (the part on the embankment side) was often buried in the earth and sand. In this case, it is difficult to remove the groove cover, and it becomes difficult to clean the inside of the gutter, repair the groove cover, and replace the groove cover.

An object of the present invention is to prevent a part of the groove lid from being buried in the earth and sand of the embankment after the rubber groove lid is once installed.

[0006]

【Example】

 1 is a partially cutaway perspective view showing a gutter structure 1 according to an embodiment of the present invention, FIG. 2 is a perspective view showing a receiving plate 2A (2B), and FIG. 3 is a partial sectional view of FIG. The bottom portion 4e of the concrete side groove member 4 has a rectangular flat plate shape. Side walls 4c and 4d extend upward from a pair of long sides of the bottom portion 4e. The lid mounting portion 4a is provided on the upper end of the side wall 4c, and the lid mounting portion 4b is provided on the upper end of the side wall 4d. A recess 8 is provided between the pair of side walls 4c and 4d. A flat lid mounting surface 5 is provided on each of the lid mounting portions 4a and 4b.

The lid mounting portions 4a and 4b are slightly thicker than the side walls 4c and 4d. The rubber lid 3 has a substantially rectangular shape in a plan view. Elongated flat portions 3a and 3b are formed on the surface side of the lid 3 substantially parallel to each other, and a slight recess is formed between the pair of flat portions 3a and 3b.

The receiving plate 2A (2B) is made of rubber. In this embodiment, the main body 2d of the receiving plate 2A (2B) has an elongated rectangular parallelepiped shape (square rod shape), and the surface 2c and the bottom surface 2a of the main body 2d are substantially flat surfaces. In this example, a total of five cylindrical protrusions 2b are formed in a line on the bottom surface 2a.

The lid 3 is placed on the pair of lid placing surfaces 5, and the lid 3 is bridged between the pair of lid placing portions 4 a and 4 b. The recess 8 is covered with the lid 3. In this example, a pair of elongated small protrusions 3c is formed on the bottom surface side of the lid 3, and each small protrusion 3c contacts the upper inner wall of the lid mounting portions 4a and 4b.

The receiving plate 2A is fixed to the lid mounting surface 5 of the lid mounting portion 4a, and the receiving plate 2B is fixed to the lid mounting surface 5 of the lid mounting portion 4b. The lid 3 is sandwiched between the receiving plate 2A and the receiving plate 2B. The surface 2c of the receiving plate 2A and the flat surface 3a have substantially the same height, and the surface 2c of the receiving plate 2B and the flat surface 3b have substantially the same height.

The columnar protrusions 2b of the receiving plates 2A, 2B are embedded in the lid mounting portions 4a, 4b by integral molding of raw concrete, whereby the receiving plates 2A, 2B are mounted on the lids. It is fixed to the placing portions 4a and 4b. That is, when forming the gutter member 4 made of precast concrete, first, the receiving plates 2A and 2B are attached to the mold, and then the fresh concrete is poured into the mold. Then, when the concrete is cured and hardened, as shown in FIG. 3, the columnar protrusions 2b are embedded and fixed in the concrete. A column-shaped recess 6 is formed on the lid mounting portion 4a (4b) side in conformity with the outer shape of the columnar protrusion 2b.

According to the above embodiment, the receiving plates 2A and 2B are fixed to both sides of the lid 3. Then, the side edge of the receiving plate 2A contacts the retaining wall side, and the side edge of the receiving plate 2B contacts the embankment side. Therefore, even if the embankment on the ground side collapses with time, the lid 3 is not buried in the sand. Therefore, the removal of the lid 3 is always easy and no trouble occurs in repairing or replacing the lid 3.

Further, since the receiving plates 2A and 2B are also formed of elastic rubber, the receiving plates 2A and 2B can also absorb and reduce the impact of the spike shoes. Since the rubber receiving plates 2A and 2B are physically embedded and fixed in the concrete gutter member, the receiving plates 2A and 2B can withstand long-term weather changes without peeling.

Further, in this example, a large number of small water holes 7 are provided in the side walls 4c and 4d. As a result, the water flowing into the recess 8 can be made to flow into the ground through the water passage hole 7. As a result, even when there is a large amount of rainfall, there is no possibility that water will overflow from the recess 8 and the ground will be blocked.

As described above, the gutter structure of this example is extremely useful in a ball play or the like. In particular, according to the investigation by the present inventor, a gutter member capable of appropriately installing the receiving plates 2A and 2B on the lid mounting surface 5 has not been used at all.

The shapes and dimensions of the respective parts shown in FIGS. 1 to 3 can be variously changed. For example, the shape of the cylindrical protrusion 2b may be a triangular prism, a quadrangular prism, a hexagonal prism, or the like, and a small protrusion may be provided on the side wall surface of the cylindrical protrusion 2b. In this case, the small protrusions further increase the mechanical joining force of the concrete of the receiving plates 2A and 2B.

[Effect of device]

 In the present invention, a rubber-made receiving plate is placed on each of the pair of lid mounting surfaces of the concrete gutter member, and a lid covering the concave portion (groove) of the gutter member is sandwiched between the pair of receiving plates. ing. That is, the receiving plates are fixed to both sides of the lid. Then, the side edge of one of the backing plates contacts the retaining wall side, and the side edge of the other backing plate contacts the embankment side. Therefore, even if the embankment on the ground side collapses with time, the lid is not buried in the sand. Therefore, removal of the lid 3 is always easy, and no trouble occurs when cleaning the inside of the gutter, repairing or replacing the lid.

Further, since each receiving plate is also made of strong rubber, each receiving plate can also absorb and mitigate the impact of the spike shoes.

A protrusion is provided on the bottom surface of each rubber-made receiving plate, and the protrusion of each receiving plate is embedded in the concrete lid placing portion by integral molding of ready-mixed concrete. Is fixed to each lid mounting portion. As described above, since each rubber receiving plate is physically embedded and fixed in the concrete groove member, each receiving plate can withstand long-term weather changes without peeling.
