Description

  The present invention relates to a side groove block. The present invention also relates to a method for placing inverted concrete in the side groove block.

  As side groove blocks for collecting and draining rainwater on the road surface, there are a side groove block used with a uniform gradient and a side groove block used with a free gradient. The side groove block used in a uniform gradient cannot be expected to have a drainage effect when the amount of drainage is small, but the free gradient side groove block has a gradient in the bottom wall, so that drainage can be efficiently discharged.

  As a method of placing invert concrete to form a gradient, after laying a U-shaped side groove block, an operator draws a black line on the inner surface of the side wall using an ink pot while looking into the side groove according to the design. There is a method of forming inverted concrete so as to coincide with this black line, using this black line as a guide. Further, as in Patent Document 1, a base plate material is laid, mortar is placed on the base plate material, an invert plate is formed on the gradient plate before the mortar is cured, and then an inverted U-shaped side groove block is formed. There is also a method of arranging in a manner that straddles the inverted version.

JP-A-7-189331

However, since the U-shaped side groove block withstands the stress applied to both side walls, it is necessary to form both side walls thickly, resulting in a problem that the cost is increased.
In addition, in the method of straddling the inverted U-shaped side groove block on the invert plate, after forming the gradient with the invert plate, the inverted U-shaped side groove block is placed on the base plate material and joined, so it takes time to work on site, The construction cost will increase.

  On the other hand, due to the good work efficiency when laying the side gutter block, the top wall, bottom wall, and both side walls are integrated, and a side gutter block with a drainage slit has appeared on the top wall, but this is structurally Because of the problem, it is impossible to form a gradient in the side groove block. Therefore, by laying a gutter block on the slope road to form a gradient and drain rainwater, or when laying under a uniform gradient, it has a drainage effect only when a certain amount of drainage can be secured, making it versatile There is a problem of being scarce.

  The present invention has been made to solve the above-described problems. That is, a side groove block integrally formed with the upper wall, both side walls, and the bottom wall, and a slit and an invert that allow a handle of a leveling jig to pass through the upper wall and move in the long side direction. A gutter block having an opening for pouring concrete.

According to the side groove block of the present invention configured as described above, when placing invert concrete,
Put concrete through the opening,
Pass the handle of the leveling jig through the slit,
By adjusting the length of the handle of the leveling jig protruding from the slit, the gradient of the poured concrete can be formed.

Therefore, the work of laying the side groove block is facilitated without having to join the base plate material and the side groove block in the field as in the prior art.
In addition, it is possible to adjust the length of the pattern of the leveling jig that protrudes from the slit while on the ground without forming the inked concrete by marking the inside of the side groove and attaching the ink line. Since the gradient in the side groove can be formed, inverted concrete can be easily placed.

  Examples of the present invention will be described below.

FIG. 1 is a perspective view of the side groove block of the embodiment. The side groove block 1 has a top wall 2, side walls 3, and a bottom wall 4 formed integrally.
FIG. 2 shows the shape of the upper wall 2. The upper wall 2 has a slit 5 and an opening 6 in the long side direction. The shape of the slit 5 is not particularly limited as long as it can pass the handle 11 of the leveling jig 10, but the width is preferably slightly longer than the diameter of the handle 11. This is to prevent dust from falling while guiding the handle 11 of the leveling jig 10 to the slit 5. Further, in addition to the case where the slit shape is continuous, as shown in FIGS. 2B and 2C, a part of the slit can be closed so as not to hinder the operation of the leveling jig 10. . As a result, since the mechanical rigidity of the side groove block can be enhanced, the thickness of the side wall can be reduced. Therefore, the side groove block can be reduced in weight and cost.
The length of the slit closing portion 7 in the slit long side direction is shorter than the length of the lower plate 12 of the leveling jig in the same direction. Thereby, the placing work of the invert concrete 20 below the slit closing portion 7 can be facilitated.

The slit 5 is continuously formed in the center of the upper wall 2 in the long side direction. Thereby, it becomes easy to apply the lower plate 12 of the leveling jig 10 to the entire bottom surface of the side groove block 1, and the efficiency of the invert concrete placing work is improved. If the upper wall 2 is wide, two or more slits 5 can be formed.
The shape and thickness of the side wall 3 and the bottom wall 4 can be arbitrarily designed according to the use of the side groove block 1. Moreover, it is also possible to embed a reinforcing member such as a reinforcing bar therein.
The bottom wall 4 can be formed with a recess, a through hole, a bottomed groove, and a slit. Thereby, weight reduction of the block 1 for side grooves can be achieved. Moreover, the invert concrete wraps around these, and the integrity of the invert concrete 20 and the bottom wall 6 improves.

Since the opening 6 is used for charging concrete and inserting a leveling jig when the side groove block is laid, the opening 6 has a size suitable for work. After laying, cover the shape according to the application and play the role of management groove. The opening 6 can be formed at an arbitrary position on the upper wall 2. For example, in the example shown in FIGS. 2C and 2D, the opening 6 is formed at the end of the upper wall 2. The shape of the opening 6 is arbitrary, and a polygon, a round shape, an oval shape, or the like can be adopted in addition to a rectangle.
The side groove block 1 having such a configuration is formed by a general-purpose concrete material.

  FIG. 3 shows an invert concrete placing method in the side groove block 1 according to the present invention. After the invert concrete 20 is introduced from the opening 6, the lower plate 12 of the leveling jig 10 is inserted from the opening 6. The portion of the handle 11 of the leveling jig 10 is passed through the slit 5, and the invert concrete 20 is moved by pushing or pulling along the slit 5, and the invert concrete 20 is placed.

  When the gradient is formed in the side groove block 1, it is necessary to adjust the thickness of the inverted concrete 20 of the bottom wall 2. Therefore, as shown in FIG. 4A, a tension wire 8 is stretched above the side groove block 1. On the other hand, as shown in FIG. 4B, the leveling jig 10 is previously provided with a reference mark 13. Then, the leveling jig 10 is pushed forward while aligning the mark 13 with the tension wire 8 to form a gradient of the inverted concrete 20. According to this method, since a black line is drawn in the side groove and the gradient of the inverted concrete is formed based on this, a reference can be provided outside the side groove block so that workability is improved. To do. Accordingly, the gradient can be formed on the inverted concrete 20 more accurately (as designed).

Next, the method for placing invert concrete at a place where it cannot be stretched is shown.
As shown in FIG. 5, a memory 14 is attached in advance to the portion of the handle 11 of the leveling jig 10. The lower plate 12 of the leveling jig 10 is inserted from the opening 6, and the concrete 11 is placed while the handle 11 of the leveling jig 10 is placed along the slit 5. At that time, since the handle 11 of the leveling jig 10 protrudes from the slit 5, the gradient of the inverted concrete can be formed while using the memory 14 as a guide. As in the first embodiment, since the reference can be provided at an easily visible outside, workability is improved.

  The present invention is not limited to the description of the embodiments and examples of the invention described above. Various modifications may be included in the present invention as long as those skilled in the art can easily conceive without departing from the description of the scope of claims.
