Since the inorganic filler is contained in the above ratio, the anti-rattle material of the present invention can suppress the stickiness peculiar to asphalt, and can achieve the hardness and ease of handling like clay in combination with the presence of the fibrous material. In addition, since the inorganic filler is contained in the above ratio, flame retardancy can be obtained while being an asphalt product. In addition, an effect as an aggregate can be obtained.

Next, a rattling preventing method according to an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding members are denoted by the same or similar reference numerals, and duplicate description is omitted.

FIG. 1 is a perspective view (a), an AA sectional view (b), and a partially enlarged sectional view (c), (d) illustrating a first embodiment of a rattling preventing method according to the present invention. ).
The partially enlarged cross-sectional view (c) is an example of a typical manhole,
(D) is an example of a typical handhole. The manhole cover 1 as a road surface component is formed so as to fit into the edge member 2 of the manhole as a support member for supporting the road surface member. That is, the lid 1 is configured to include a side surface 1a from which a part of a cylinder is taken out, and a plane 1b obtained by cutting the side surface at a right angle. The edge member 2 includes a cylindrical inner surface portion 2a facing the side surface 1a, Step 2b facing plane 1b
It is comprised including. Both the lid 1 and the edge member 2 are made of, for example, cast iron. The rim member 2 is mounted on the ground 3 on the ground on a suitable concrete basis.

The lid 1 and the edge member 2 are castings and cannot be made very precisely. In addition, in order to absorb distortion and distortion caused by twisting during installation on the ground, the side surfaces 1a and 2a of the two are combined. There are some gaps between them. In addition, a gap is generated between the flat surface 1b and the stepped portion 2b where the flat surface 1b overlaps due to wear due to rotational movement and vibration during use of the lid 1. In order to prevent rattling due to such gaps, in the present embodiment, three packs of rattling preventing material (described in FIG. 2) according to the embodiment of the present invention are used.
It is applied to parts.

In the embodiment shown in FIG. 1A, the anti-rattle material pack 11 is used at three places. However, it is sufficient that one or more places are provided, preferably two or more places, more preferably three places. Most preferably, it is four places. Although the economy gradually decreases, five or more locations may be used. It is a typical usage method to attach the anti-rattle material pack 11 so as to cover both the side surface 2a and the stepped portion 2b.

The anti-rattle material 11 is made of cellophane paper 13
The bag 13 is provided with a cut on one side (back side) of the bag 13 (see FIG. 2 (b)) to prevent the anti-rattle material 1.
2 is exuded on one side, and that side is adhered to the edge member 2. The lid 1 is placed with the cellophane paper on the surface as it is. The protruding portion of the cellophane paper bag may be cut off after the lid 1 is closed.

At this time, the cellophane paper on the back surface may be peeled off (see FIG. 2C), the back surface of the anti-rattle material may be exposed, and the exposed surface may be attached to the edge member 2.

The anti-rattle material 12 is used to cover the lid 1 like clay.
And the edge member 2. The remaining cellophane paper 13 on the front side rotates very little by little due to the action of the vehicle or the like on which the lid 1 passes, but is consumed and peeled off accordingly. However, at that time, the anti-rattle material 12 also has reduced adhesiveness, and typically remains attached to the edge member 2 so that when the lid 1 is opened, the lid 1 is attached. But remains on the edge member 2. When the lid 1 is closed again, the rattle preventing material 12 is effective as it is, but it is preferable to use a new rattle preventing material 12 at a place other than the initial three places just in case.

Referring to FIG. 2, an embodiment of the anti-rattle material of the present invention will be described. The anti-rattle material 12, which is an embodiment of the present invention, is weighed into a cellophane paper 13 by an appropriate amount, for example, 30 grams. This is rolled to form a flat shape having a thickness of 5 mm, a width of 70 mm, and a length of 90 mm. The color is black and the hardness is about the size of the earlobe. Because it is stored in cellophane paper, it is easy to handle.

As shown in FIG. 2B, the cellophane paper can be easily cut. As shown in the figure, if a large cross mark is made, the anti-rattle material oozes out of the cut, and this surface can be attached to the edge member of the manhole.

As shown in FIG. 2C, the cellophane paper can be easily torn, and for example, the cellophane paper on one of the front surface and the back surface can be peeled off and removed. In this manner, as described with reference to FIG. 1, it is possible to apply an application such as attaching the side from which the cellophane paper has been peeled to the edge member. A large cross-cut may be made on the surface to be peeled, and the whole or at least a part thereof may be peeled off.

The size of the bag, and thus the size of the flat anti-rattle material, is 5 mm thick, 70 mm wide and 90 mm long.
In addition to mm, it can be appropriately determined. The amount of one pack is 30 grams, 20 grams, 50 grams, and 70 grams.
It can be appropriately determined as grams.

It is preferable that the size of the bag is determined with a margin larger than the length of the flat and rattling preventing member. Preferably, the length is not less than 2/3 and about 2 times, but most preferably about 2 times.

In the embodiment shown in FIG. 2A, the length of the flat anti-rattle material is 90 mm, which is twice as long as 180 mm.
mm bag 13 is used. By doing so, the surplus portion is bent to the edge portion of the manhole or the ground portion as shown in an example in FIG. 1C, and a weight (not shown) is placed thereon to prevent rattling. It is easy to hold the material at the edge, especially when there is no step on the edge unlike the illustration, and by holding in this way, the work of putting the lid on becomes easy.

The surplus portion of the bag 13 is substantially equal in length to the flat rattling preventing material portion, so that it can be easily handled without being obstructed even when it is folded over here.

Although the description has been made with cellophane paper, other plastic sheet bags such as vinyl sheets may be used, or oil paper may be used. If a sheet of a material that does not penetrate the organic solvent and does not penetrate the asphalt, which is a component of the rattling prevention material, can be stored for a long period of time and does not stain the hands during handling. Therefore, handling in distribution is easy.

As another application, a non-woven bag can be used. Alternatively, the nonwoven fabric sheet may be flattened and applied to the front and back surfaces of the anti-rattle material. The nonwoven fabric penetrates organic solvents and asphalt, so it needs to be consumed in a short period of time. It can act as an inhibitor. It can also be used as a packing. The nonwoven fabric is preferably made of chemical fiber.

Another embodiment of the anti-rattle material according to the present invention will be described with reference to a perspective view (a) of FIG. 3 and a partially enlarged cross-sectional view (b) of FIG. In this embodiment, in addition to the case of FIG. 2, a mesh 14 as a core material disposed near one surface of a flat anti-spreading material 12 having a front surface and a rear surface is provided. Is provided. The mesh 14 is a net woven with a fibrous wire. The mesh is generally a stitch material having an opening of a size equal to or greater than the thickness of a wire constituting the mesh. In one example, a grid-like mesh having a chemical fiber wire having a thickness of about 0.5 mm and a wire interval of 2.5 to 4 mm was used. With this configuration, a sufficient reinforcing effect during use was obtained, and the effect of preventing scattering was also high.

The shape of the mesh may be a honeycomb shape or a diamond shape in addition to a grid shape. The mesh may be formed by weaving a wire, or may be formed by forming plastic into a mesh.

The core 14 may be a non-woven fabric or a woven fabric in addition to the mesh. Core material 14
May be not only one or the vicinity of the front and back surfaces, but also both surfaces or the vicinity thereof.

With this structure, the core member 14 is provided, so that the anti-rattle material is reinforced. If the core material 14 is made of, for example, a fine mesh or nonwoven fabric, an effect of preventing scattering can be exerted.

Although the core member 14 exerts a reinforcing effect even without a bag, it is preferable to be housed in the bag 13 as shown in the figure for handling.

Vertical and horizontal wires (threads) of a grid-like mesh
May be woven in a plain weave, but as shown in the partially enlarged cross-sectional view of (b), the warp and the weft are placed on only one of the front side and the back side, respectively, and are manufactured by sticking to each other. In this case, if the weft yarns orthogonal to the direction from the opening to the bottom of the bag 13 are arranged so that the weft yarn orthogonal to the bag 13 is on the side closer to the bag 13 and the warp yarns orthogonal to the weft yarns are on the inner side, the anti-rattle material is added to the bag 13. The work becomes easier when packing into 13,
At the time of use, the weft thread is hung on the edge portion 2 to prevent slipping and is good.

Even if the core material 14 is disposed on the front surface or the back surface of the anti-rattle material 12, the anti-rattle material 12 permeates into the core material 14 with time, or the core material 14 1
As a result, it is arranged near the front surface or the back surface. Further, the core member 14 is made of the anti-rattle material 1.
2 may be located substantially at an intermediate position between the front surface and the back surface, but preferably, as shown in FIG. 3B, one of the front surface and the back surface or its vicinity.

With reference to FIG. 4, another embodiment of the anti-rattle material of the present invention will be described. (A) shows a case in which cellophane paper 13a is applied to the upper and lower surfaces of a rattling preventing material formed in a thick flat shape, that is, an ingot shape. At the site, first, the cellophane paper on one of the upper surface and the lower surface is peeled off, the cellophane paper is placed on the ground side, and then the cellophane paper on the opposite side is peeled off, and the road surface component may be placed. The cellophane paper on the opposite side does not have to be peeled off.

(B) is a sandwich-like material in which the anti-rattle material which is flatter than (a) is sandwiched between wider cellophane papers 13b. As compared with the embodiment of FIG. 2, the work is further facilitated because only one of the two sheets needs to be peeled off rather than breaking the bag of cellophane paper.

(C) shows an anti-rattle material formed into a tape and wound into a roll. At this time,
Cellophane paper may be applied to one side, and cellophane paper may be perforated at an appropriate length to facilitate cutting. Cellophane paper may be applied to both sides as well as to one side. At this time, when perforations are to be made, it is necessary to make them at substantially the same position on both sides.

In the above embodiment, a core material as described with reference to FIG. 3 may be used in combination.

As described above, cellophane paper has been described as an example of the separation member of the rattling prevention member. However, as described above, a plastic sheet or oil paper may be used, or a tape made of Teflon (registered trademark) may be used. So asphalt,
Alternatively, if a material that is sparse with respect to the organic solvent is used, it is easy to peel it off and the working efficiency can be improved.

Referring to FIG. 5, another embodiment of the present invention will be described. This embodiment is an example in which the anti-rattle material of the present invention is applied to a lining plate for covering a road surface opening during subway construction or the like to secure traffic. In the figure, a lining plate 31 as a road surface component is placed on an H-shaped steel beam 32 as a support member that is passed over an opening in the road surface. At that time, first, the anti-rattle material of the present invention is applied to the upper surface of the H-shaped steel beam,
In particular, the anti-rattle material 12 formed in an ingot shape as described with reference to FIG. The lining plate 31 is placed thereon.

In this way, even if the H-shaped steel beam 32 is distorted, or if the lining plate 31 is distorted, the rattling preventive material 12 fills it, so that the rattling is reduced. Does not occur.

In the above embodiment, the anti-rattle material of the present invention has been described in the case where the anti-rattle material is molded in a bag or cellophane paper or the like is applied to the upper and lower surfaces. It is possible to prevent rattling by transporting, making an appropriate amount of dumplings on site, and sandwiching them in gaps. Although the manhole has been described as being circular, it may be elliptical, square, or rectangular. In the case of a square or a rectangle, it may be applied to each of four sides or each of four corners, that is, to four places. Alternatively, it may be applied to a total of eight places on both ends of each side or both sides of each corner.

Although the above embodiment has been described with reference to a manhole, a handhole may be used.

As described above, the anti-rattle material is formed in a pack or ingot shape at intervals, and is used continuously, that is, in the example of FIG. May be used. Although the amount is necessary, the function of the packing for blocking odors can be exhibited particularly in sewage manholes and the like.

[0061]

As described above, according to the present invention, 5 to 15
Since the fiber material is contained in parts by weight, the anti-rattle material does not become loose and can maintain its integrity, and since it contains 65 to 160 parts by weight of the inorganic filler, it is possible to suppress the stickiness peculiar to asphalt. Easy to handle.
