Field of the Invention The present invention relates to a method for mounting a gutter cushion material embedded and fixed on a cover receiving surface of a concrete gutter block or a contact surface of a concrete gutter cover with a gutter block. Formed in the concrete manufacturing form, the lid receiving surface forming portion comprising a groove surface forming portion and a convex portion, in order to prevent the intrusion of concrete from both end portions of the side groove buffer material, The side groove buffer formed slightly wider than the gap between the groove surface forming portion and the convex portion,
The present invention relates to a method for mounting a gutter buffer, which has a feature in that it is forcibly press-fitted and sandwiched between a groove surface forming portion and a convex portion of the lid receiving surface forming portion.

[0002]

2. Description of the Related Art For example, there is a concrete gutter block made of concrete, which is a gutter block provided at a side edge of a road or the like. And conventionally, it is embedded and fixed on the lid receiving surface of the concrete gutter block,
There is a gutter of the gutter lid placed on the lid receiving surface, and a gutter cushioning material formed of a rubber material or various resins for preventing noise caused by the gutter.

[0003] Such a gutter cushioning material is not only embedded and fixed in a concrete gutter block, but also embedded and fixed in a concrete gutter cover made of concrete as a lid of the gutter block. .

Generally, a concrete gutter block or a concrete gutter cover is manufactured by casting concrete in a manufacturing formwork, and the cushioning material for the gutter is placed in the manufacturing formwork before the concrete is cast. In advance. The conventional side groove cushioning material has a flat side end surface as shown in FIG. 10, for example.

[0005]

However, since the conventional side groove cushioning material has a flat side end surface, when concrete is poured into the production formwork, the gap between the side end surface and the production formwork is reduced. Concrete was easy to penetrate into the area.
When concrete intrudes between the side end surface of the gutter cushion and the production formwork, as shown in FIG. 11 or FIG. 12, the gutter cushion of the manufactured concrete gutter block or concrete gutter lid is formed. Unnecessary concrete adhering portions are formed on the side end surfaces of the gutters, causing a problem that the gutter buffer material does not perform its original function.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to prevent concrete from entering between a side end surface of the concrete and a production form when the concrete is poured. Another object of the present invention is to provide a method for mounting a gutter cushion for facilitating easy removal of unnecessary concrete attachment portions even if concrete invades and forms them with a simple configuration.

[0007]

SUMMARY OF THE INVENTION The gist of the present invention adopted to solve the above-mentioned problems is as described in the appended claims, "A concrete gutter block or a concrete gutter cover is formed. A gutter buffer in which a concrete manufacturing form to be used is provided with an anchor portion to be embedded in the concrete gutter block or the concrete gutter cover on one surface of a body having a side end surface formed into a saw blade. A mounting method for mounting a material, wherein a cover receiving surface forming portion formed in the concrete manufacturing form and including a groove surface forming portion and a convex portion includes the gutter buffer material. In order to prevent the intrusion of concrete from both side end portions, the side groove cushioning material formed slightly wider than the gap between the groove surface forming portion and the convex portion is provided between the groove surface forming portion and the convex portion. Forcibly press fit Sometimes the mounting method "gutter cushions, characterized in that lifting.

The gutter cushioning material 10 of the present invention is constructed as described above. Therefore, the following operation will be described below with reference to the reference numerals attached to the drawings. First, a concrete gutter block 20 is provided on one side of the main body 12 of the gutter cushioning material 10.
Alternatively, an anchor portion 11 buried in a concrete gutter 30 for fixing the gutter cushioning material 10 is provided. Therefore, the gutter cushioning material 10 is firmly fixed to the concrete gutter block 20 or the concrete gutter cover 30.

Next, the main body 12 has a side end surface having a saw-toothed cross section. For this reason, if the gutter cushioning material 10 is disposed in the manufacturing form 100, for example, as shown in FIG.
Since the side end surface comes into contact with the production form 100 at the saw-shaped tip, concrete invades from the uppermost saw blade portion 12a of the saw blade temporarily due to the pressure at the time of placing concrete. However, since the intrusion pressure of the concrete is reduced from the casting pressure of the concrete, the amount of the intruding concrete is small, and as shown in FIG. 8, only a small amount of the concrete adhesion portion is formed. Become. Even if the adhered portion of concrete is formed in an unnecessary portion in this way, the adhered portion can be easily removed by flipping it with a finger or the like.

When the concrete enters the lower saw blade portion 12b or lower, the concrete intrusion pressure is further reduced by the lower saw blade portion 12b, so that the concrete hardly penetrates below the saw blade portion 12b. Become.
That is, the intrusion of concrete over the entire height of the side end surface of the gutter cushioning material 10 is caused by the uppermost saw blade portion 12a.
And the lower saw blade portion 12b.

Further, even if the concrete invades below the lower saw blade portion 12b and the concrete adhesion portion is formed over the entire height of the gutter cushioning material 10, the concrete adhesion portion is formed as described above. Since it is formed by concrete that has invaded by the reduced pressure and formed by a small amount of concrete, it can be easily removed by flipping with a finger or the like.

Further, even if the concrete enters into the entire gap between the saw blade-shaped side end faces and the concrete adhesion portion is formed, as shown in FIG. It is very fragile at the side edge surface of the cushioning material 10 and can be easily removed by flipping with a finger or the like. In this case, since the concrete attachment portion is very brittle, even if it is not particularly removed by flipping with a finger or the like, when it is used for the concrete gutter block 20, the gutter cover 30a is naturally impacted when it is placed. If it is removed and is adopted for the concrete gutter 30, it can be naturally removed by an impact when the gutter is placed on the gutter block.

It is integrally formed into a long shape by a rubber material, and is cut into a desired size for use.

The two end surfaces of the main body 12 are each formed in a three-stage saw blade shape in cross section. The shape of the both end surfaces of the main body 12 is not limited to this, but may be a two-stage or four-stage or more saw blade shape as long as the cross section is a saw blade shape.

On one surface of the main body 12, two anchor portions 11 each having a substantially arrow-shaped cross section are provided, and the concrete gutter block 20 or the concrete gutter cover 3 is provided.
When buried in 0, the gutter cushioning material 10 is firmly fixed. The shape of the anchor portion 11 is not limited to this, and may be any shape as long as the gutter cushioning material 10 is firmly fixed when buried in concrete.

Incidentally, the concrete gutter block 20 or the concrete gutter cover 30 is generally formed by casting concrete into a production form 100. Then, the gutter cushioning material 10 of the present invention is pre-arranged in the production mold 100, and then concrete is poured into the production mold 100, and the formed concrete gutter block 20 is formed.
Alternatively, the anchor portion 11 is buried and fixed to the concrete gutter 30.

Next, the concrete gutter block 20
Alternatively, the manufacturing process of the concrete gutter 30 will be described.
In addition, since the manufacturing process of the concrete side gutter cover 30 is the same as the manufacturing process of the concrete side gutter block 20 formed by the manufacturing formwork 100, it is omitted, and the manufacturing process of the concrete side gutter block 20 will be described below.

First, FIGS. 2 to 4 show an example of a production formwork 100 of the concrete gutter block 20. FIG.
The production formwork 100 is made of a concrete gutter block 2.
A groove surface forming portion 111 for forming the groove surface 21 of the first groove, and the buffer material 1 for a side groove of the present invention, which is provided at the lower end of the groove surface forming portion 111 and protrudes.
0 on which the gutter cover 30a of the concrete gutter block 20 is placed, that is, the lid receiving surface 12
Body 11 having a lid receiving surface forming portion 112 that forms
0, and a side plate 120 that is openably and closably supported on both sides of the convex body 110 and forms the side surface 13 of the concrete gutter block, and a concrete side gutter block 20 that is openably and closably supported on both sides of the convex body 110. And an end face plate 130 that forms the end face 24. In the present embodiment, as shown in FIG. 7, a convex portion 113 is provided upright on a side edge of the lid receiving surface forming portion 112, and is placed on the lid receiving surface forming portion 112 during concrete casting. It is possible to sandwich the formed side groove buffer material 10. That is, when the gutter cushioning material 10 is forcibly press-fitted into the lid receiving surface forming part 112 and placed, it is sandwiched between the groove surface forming part 111 and the convex part 113 on both side ends thereof, so that it is possible to prevent displacement. Can be. The projection 113 is formed by welding a steel material.

When concrete is poured into the production form 100, the gutter cushioning material 10 is placed on the lid receiving surface forming portion 112 in advance. Here, since both ends of the side groove buffer 10 have a saw-toothed cross section as described above, the side groove buffer 10 slightly wider than the gap between the groove surface forming portion 111 and the convex portion 113 is used. Then, the groove material 10 can be sandwiched between the groove surface forming portion 111 and the convex portion 113 only by press-fitting the side groove buffer material 10 with a small force. Therefore, the buffer material 1 for the side groove with respect to the distance between the groove surface forming portion 111 and the convex portion 113 is formed.
Even if the width of 0 is slightly increased due to a dimensional accuracy error or the like, no problem occurs.

Next, the side plate 120 and the end plate 130 are closed, and the convex body 110, the side plate 120, and the end plate 130 form a concrete casting space, and concrete is poured into the casting space. . Then, after the concrete has hardened, the side plate 120 and the end plate 130 are opened, and the production form 1

Thus, a high quality concrete gutter block 20 in which 0 is exposed is obtained.

The gutter cushioning material 10 exposed on the lid receiving surface 22 of the concrete gutter block 20 is firmly fixed by its anchor portion 11.
When the concrete side gutter block 20 is withdrawn from the side gutter 0, since both side end surfaces of the side gutter cushioning material 10 are sandwiched between the groove surface forming portion 111 and the projection 113 with a small force as described above, The cushioning material 10 is securely pulled out of the production form 100.

It is assumed that the cushioning material 1 for the gutter on the lid receiving surface 21 of the manufactured concrete gutter block 20.
As shown in FIG. 8, a small amount of concrete adhering portion is formed on the side end surface of No. 0, or concrete adhering portion is formed on all portions of the sawtooth-shaped gap as shown in FIG. 9. However, since the adhesion portion of the concrete is very brittle as described above, it can be easily removed.

On the other hand, when the concrete side groove cover 30 is formed by similarly casting concrete with the production form of the concrete side groove cover 30, the side groove is formed on the contact surface 31 with the side groove block as shown in FIG. A high-quality concrete gutter 30 in which the cushioning material 10 is reliably exposed is obtained. Here, one side end surface of the gutter cushioning material 10 is buried in the concrete gutter cover 30, and the buried saw blade-like side end surface is locked to the gutter cushioning material 10. Therefore, the concrete gutter cover 3 can be formed not only by the anchor portion 11 but also by this side end surface.
Thus, the side groove cushioning material 10 is reliably prevented from being turned up.

[0025]

As described above in detail, the gutter cushioning material of the present invention comprises a main body having a side end surface having a saw-toothed cross section, and an anchor protruding from one side of the main body. It is firmly fixed to the concrete gutter block or concrete gutter lid by the anchor part, and the concrete-attached part is not formed at that part by the side edge surface with a sawtooth-shaped section, and temporarily Even if a concrete adhering portion is formed in the portion, it can be easily removed, and the gutter cushioning material is reliably exposed.

Therefore, according to the present invention, it is possible to prevent concrete from intruding between the side end face and the production form when the concrete is poured, and it is also possible to prevent the concrete from intruding and unnecessary adhesion portions of concrete. Even if it is formed, it is possible to provide a method of attaching the side groove cushioning material with a simple configuration so that it can be easily removed.
