Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fly-neck rubbing tool such as a manhole used for road surface construction, which can be easily installed or removed and can be used repeatedly.

[0002]

2. Description of the Related Art Paved roads are damaged or worn by use. Therefore, it is necessary to reconstruct the pavement by excavating the pavement at an appropriate time. Since the construction of will be the last, if a manhole or water treatment basin is installed on the road to be constructed, the top neck of the manhole etc. will be attached to the road surface after removing the surface layer by the thickness of the surface layer when the surface layer is removed. It will fly out.

Even in this state, the road is opened for the passage of the vehicle. Although this road is regulated as a slow section, it is not only dangerous for the passage of the vehicle but also the flying neck portion. In order to eliminate the impact of the vehicle on the above, a "rubbing material" is applied around the protruding neck portion.

That is, as shown in FIG. 6, the asphalt a is laid in a smooth slope shape at a distance of 70 to 80 cm from the outer circumference of the upper neck b of the manhole, while it must be removed during the surface layer construction. Therefore, the sand c is laid in the portion located on the lower surface of the asphalt a to be laid in consideration of the convenience of peeling. And this is called a rub.

[0005]

Therefore, such a rubbing work must be carried out for each projecting neck portion of each manhole or the like, and the work is not only complicated but also the above-mentioned rubbing work is carried out once. It is also extremely uneconomical because it is used only for the construction work, and since the above-mentioned sizing material or slicing work is usually done at the economical burden of the contractor, the sizing material and sizing work are saved. However, there are various problems such that the slope may be laid on a steep slope.

[0006]

In order to solve the above-mentioned problems, a rubbing tool for a flying neck such as a manhole used for road surface construction according to the present invention (claim 1) has a manhole, etc. A hole having an inner diameter larger than the outer diameter of the protruding neck portion is formed, and the whole is formed in a trapezoidal cross section.

In order to solve the above-mentioned problems, the present invention provides a shaving tool for a protruding neck portion such as a manhole used for road surface construction according to the present invention. A hole having an inner diameter larger than that of the spacer is formed with a trapezoidal cross-section and can be inserted between the outer circumference of the protruding neck portion and the inner circumference of the hole of the main body of the rubbing tool. It was done.

In the above, the main body of the abrasion tool and the spacer are formed of a plurality of divided pieces, which can be connected to each other, or the upper surfaces of the main body of the abrasion tool and the spacer are formed as rough surfaces having irregularities. There is also.

[0009]

[Function] That is, by installing a preformed rubbing tool main body on the outer periphery so as to surround the neck of a manhole or the like protruding to the road surface from which the surface layer has been removed, the rubbing work is completed If there is a gap between the hole in the center of the main body and the outer periphery of the pop-out neck portion, it should be filled with a spacer to facilitate installation or removal in any case and to use it repeatedly. It will be possible to do so.

[0010]

Embodiments Next, an embodiment of a flying neck rubbing tool such as a manhole used for road surface construction according to the present invention will be described with reference to FIGS. 1 to 6. In FIG. Is a doughnut-shaped rubbing tool body, and the inner diameter of the hole 2 is formed to be larger than the outer diameter of at least the neck portion of the manhole or the rod. In the above, the shape of the hole 2 is not limited to the circular shape as in the illustrated embodiment, but may be a quadrangle because it changes depending on the shape of the projecting neck portion such as a manhole or a rod.

As shown in FIG. 2, the main body 1 of the rubbing tool is formed into a trapezoidal shape, and the main body 1 of the rubbing tool is made of a material such as rubber, synthetic resin, wood or metal. That is, it is formed of a material that can withstand the passage of the vehicle on the upper surface of the main body 1 of the rubbing implement.

When the main body 1 of the rubbing implement is used, as will be described later, where the protruding neck portion such as the manhole is to be housed in the hole 2 of the main body 1 of the rubbing implement, the diameter of the neck portion is all The manholes and the like are not necessarily formed in the same manner. Therefore, when the neck portion is inserted into the hole 2, a relatively large void portion may occur between the outer periphery of the neck portion and the hole 2. However, if such a large void is generated, the installation of the main body 1 of the rubbing implement is not stable when the vehicle is passing, and as a result,
Therefore, it is preferable that the outer shape of the projecting neck portion and the inner diameter of the hole 2 are preferably formed so as to coincide with each other. In order to eliminate the practical complication of having to prepare 1 in advance, the spacer 3 may be used by being engaged with the void portion.

That is, the shape of the spacer 3 is such that it can be accommodated in the void portion, and as long as it is,
A plurality of types having different diameters may be concentrically arranged to provide a plurality.

The spacer 3 is also made of rubber, synthetic resin,
A material such as wood or metal, that is, a material whose upper surface can withstand passage of a vehicle is formed.

Also, the main body 1 of the rub and the spacer 3
Can be formed integrally with each other, but the weight may be very large depending on the material used for them, and it is expected that the handling will be inconvenient. These may be formed of a plurality of divided pieces 4 as shown in FIGS. 4 and 5, respectively, and may be connected and used at the time of use. The spacer 3 may be formed in advance, but sand or normal temperature mixture may be used. In any case, the area or amount occupied by the spacer 3 needs to be particularly large. Since it is not a thing, it may be used depending on the situation at the site.

Further, since the vehicle passes through the upper surfaces of the main body 1 and the spacer 3, the unevenness (rough surface) having an appropriate shape may be formed on the upper surfaces to prevent slippage.

However, the main body 1 of the rubbing tool so that the neck portion of the manhole or the like that pops out on the road surface after the peeling of the surface layer enters into the hole 2
Are arranged so as to surround the neck. The rubbing work is completed when the rubbing tool body 1 is integrally formed and the hole 2 has an inner diameter that matches the outer shape of the neck portion.

However, the inner diameter of the hole 2 of the main body 1 of the abrasion tool is formed to be relatively larger than the outer diameter of the neck portion of the manhole,
Therefore, when a relatively large gap is formed between the outer periphery of the neck and the inner periphery of the hole 2, the spacer 3 is arranged so as to fill the gap, or sand or a room temperature mixture is used as described above. Fill.

Further, the main body 1 of the rubbing tool and the spacer 3
When the divided pieces 4 are formed, the rubbing work is completed by connecting the divided pieces 4.

When the main body 1 and / or the spacer 3 are to be removed, they may be removed. The main body 1, the spacer 3 and the like are simply set as described above. Therefore, it is sufficient to simply remove it when removing it.

[0021]

As described above, according to the present invention, the manipulating tool for a protruding neck portion such as a manhole used in road surface construction has an inner diameter larger than the outer diameter of the protruding neck portion of a manhole. With a trapezoidal cross section, or with a main body of the rubbing tool having a hole with an inner diameter larger than the outer diameter of the protruding neck of a manhole, etc. Since it is formed of a spacer having a shape that can be inserted between the outer circumference of the pop-out neck portion and the inner circumference of the hole of the main body of the rubbing tool, the preliminarily molded rubbing tool main body can be used for the road surface without the surface layer. The rubbing work is completed by installing it on the outer circumference so that it surrounds the neck of the manhole, etc. that pops out to the outside, and temporarily creates a gap between the central hole of the rubbing tool body and the outer circumference of the neck of the manhole, etc. In this case, it is possible to fill this with a spacer or sand, a room temperature mixture, etc., and in any case, it is possible to facilitate installation or removal and to enable repeated use. Have.

Further, when the main body of the abrasion tool and the spacer are made of rubber or synthetic resin, since they have flexibility, they are easy to adapt to the shape of the road surface, and thus can be used stably and mass produced. Since it is possible, it is possible to provide it at a low price.

On the other hand, the durability of the main body of the rubbing tool and the spacer formed of metal or wood can be improved.

Further, by constructing the main body of the abrasion tool and the spacer by the combination of the divided pieces, the handling becomes good and the workability is improved regardless of the material or the shape, and the spacer is used. By forming a large hole in the main body of the rubbing tool,
It has the effect that it can be universally used for manholes of any outer diameter.
