Description

  The present invention relates to a side groove formwork, and more particularly, to a side groove formwork for forming a side groove main body or a groove lid used as a side groove.

  For concrete side grooves that cover the groove body on the side groove body, the side groove body cover receiving surface and groove cover body are designed to alleviate the impact of pedestrians, bicycles, cars, etc. A rubber cushioning material is interposed between the lower surface and the lower surface.

  In the step of manufacturing the side groove, a procedure of embedding a rubber cushioning material in a predetermined portion of the side groove body or the groove lid at the same time as molding the side groove body or the groove lid has been adopted (for example, Patent Document 1). reference).

  By the way, among the side groove main body and the groove lid body of the side groove, in particular, the groove lid body may be put into the recycling process and reused when the side groove main body is aged or damaged. The groove lid was crushed and used for road repairs and the like.

  In this regard, when reusing the groove lid provided with the rubber cushioning material, it is necessary to perform a sorting operation of removing the cushioning material attached to the groove lid body or the side groove main body from the groove lid body or the side groove body as a previous process. . Such separation work is also required to be performed when the side groove body and the groove lid of the aged side groove are removed.

  Therefore, regarding the workability of the above-described sorting operation, when the rubber cushioning material is embedded in a predetermined portion of the side groove body or the groove lid body at the same time as the molding of the side groove body or the groove lid body, the cushioning material is used in the side groove body or the groove lid body. Since it was embedded in the concrete layer of the lid so that it could not be easily removed, it was difficult to remove the cushioning material.

FIG. 15 is a cross-sectional view of a main part of a conventional groove lid body 100 to which the cushioning material 120 is attached. As shown in the figure, in this groove lid body 100, in the step of molding the groove lid body 100 with concrete, the rubber cushioning material 120 in which the mounting ribs 121 having an inverted trapezoidal cross section are formed. The dovetail-shaped mounting groove 102 is provided in a molding space of a molding frame through an attachment (not shown), and concrete is poured into the molding space of the molding frame, and the concrete is cured. The buffer material 120 is attached to the groove lid body 100.
Then, after curing the concrete, the attachment is pulled out from the attachment groove portion 102 of the groove lid body 100 in the longitudinal direction of the groove lid body 100, and the attachment is removed from the groove lid body 100.
Further, the cushioning material 120 has a length covering the entire length of the groove cover body 100 or substantially the entire length, and the cushioning material 120 is not easily detached from the groove cover body 100 by the inverted trapezoidal mounting rib 121 of the cushioning material 120. It has a structure.

  However, in the groove cover body 100 formed using the conventional side groove mold, the attachment is embedded in the mounting groove portion 102 of the groove cover body 100 immediately after the mold release as described with reference to FIG. Therefore, there is an inconvenience that the attachment has to be removed from the groove lid 100 and collected, and the same inconvenience is the side groove body formed by using the conventional side groove formwork. There was also about.

  Further, in the work of removing the attachment from the groove lid body 100 formed using the conventional side groove mold, the attachment having a relatively long length is pulled out from the mounting groove portion 102 of the groove lid body 100 in the longitudinal direction of the groove lid body 100. There was a problem that it was forced to perform such annoying work. This problem has also existed in the side groove body formed using the conventional side groove formwork.

The present invention has been made in view of the above situation and problems, and when a side groove body or a groove cover body to which a cushioning material is attached is molded from concrete, the attachment is removed from the side groove body or the groove cover body. The need for can be eliminated.
In addition to enabling the cushioning material to be immediately attached to the side groove body or groove lid after molding, the cushioning material can be easily attached, and the cushioning material can be easily removed at the time of sorting. It is an object of the present invention to provide a side groove mold that can form a side groove body or a groove lid body of a side groove that can be formed.

  In addition, the present invention is free to change the arrangement pattern of the cushioning material for the side groove main body or the groove lid body formed by devising the shape of the attachment provided at the time of molding on the mold body forming the molding space. The side groove mold that can increase the degree and eliminates the need to make any modification to the mold body even when changing the arrangement pattern of the cushioning material for the molded side groove body or groove lid body. The purpose is to provide a frame.

  Furthermore, an object of the present invention is to provide a side-groove formwork in which an attachment can be easily attached to and detached from the formwork body in a one-touch manner.

  A side groove mold according to the present invention includes a side groove main body, a groove lid mounted on the lid receiving surface of the side groove main body, and a cushioning material interposed between the lid receiving surface and the lower surface of the groove lid. A side groove mold for forming a side groove, a mold body forming a molding space for the side groove body or the groove lid, and the lid receiving surface or the groove provided in the mold body. Mounting hole molding for forming a mounting hole into which the convex insertion portion of the cushioning material can be fitted on the lid receiving surface or the lower surface of the groove lid by being provided on a molding surface for molding the lower surface of the lid. The mounting hole forming member includes a coupling means for the molding surface, and the outer surface shape becomes narrower as it approaches the top. In this device, the mounting hole forming member corresponds to the attachment described above.

  According to this device, since the outer surface shape of the mounting hole forming member as an attachment is narrower as it approaches the top, the mounting hole forming member is arranged on the molding surface of the mold body to form the mold body. When the concrete is poured into the space and the mold is released after being cured, the mounting hole forming member remains on the molding surface of the mold body, and the molded side groove main body or the groove lid body has the mounting hole forming member missing. A trace remains and the trace of the mark functions as a mounting hole for the cushioning material. For this reason, the buffer material is immediately attached to the side groove body or the groove lid body by fitting the convex insertion portion of the buffer material into the mounting hole formed in the side groove body or the groove lid body. In addition, since the shape of the mounting hole is formed so that the portion closer to the hole bottom is narrower by the mounting hole forming member, the convex insertion portion of the buffer material is attached when the buffer material is mounted and removed. It can be easily inserted into and removed from the hole, which is useful for easily performing an operation for attaching or removing the cushioning material to or from the side groove body or the groove lid.

  In the present invention, the coupling means is preferably a magnet that can be attracted to the molding surface. According to this, when the mounting hole forming member is arranged on the molding surface of the mold body, it is only necessary to adsorb the magnet as a coupling means of the mounting hole forming member to the molding surface, and the mounting hole to the molding surface. Since it is possible to freely select the deployment position of the molded member and the number of the molded members used, it is possible to freely change the arrangement pattern of the cushioning material for the molded side groove main body or groove cover body as necessary. In addition, even when changing the arrangement pattern of the cushioning material for the molded side groove body or groove lid body, it has an excellent effect that it is not necessary to make any modification to the formwork body. The

  In the present invention, the outer surface shape of the mounting hole forming member described above may be narrower as it approaches the top as described above in a broad sense. Therefore, as long as this is the case, the mounting hole forming member may have a long rib shape with directionality. However, a preferable outer shape of the mounting hole forming member is a truncated cone or a polygonal frustum. If the outer surface shape of the mounting hole forming member is set in this way, the mounting hole forming member becomes a small block shape having no directionality, so the arrangement pattern of the cushioning material for the molded side groove body or groove cover body There is an advantage that the degree of freedom of change is remarkably increased.

  As described above, according to the side groove mold according to the present invention, when the side groove body or the groove lid body to which the cushioning material is attached by the retrofitting method is molded with concrete, the molded side groove body or groove lid body is immediately after being molded. There is a convenience that a cushioning material can be attached to. In addition, because the shape of the mounting holes of the side groove body and the groove lid body is so narrow that it approaches the hole bottom, the cushioning material can be easily attached to the mounting holes. In addition, it is possible to mold the side groove body or the groove lid body of the side groove from which the cushioning material can be easily removed at the time of separation.

  Further, according to the present invention, it is possible to employ a magnet as the coupling means of the mounting hole forming member, so that the degree of freedom in changing the arrangement pattern of the cushioning material for the molded side groove body or groove cover body is increased, Moreover, even when changing the arrangement pattern of the cushioning material for the molded side groove body or groove lid body, an advantage or effect that it is not necessary to add any modification to the mold body can be obtained, There is also an effect that the attachment can be easily attached to and detached from the mold body in a one-touch manner.

  FIG. 1 is a schematic perspective view of a mold A according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a mounting hole forming member 7.

  The mold A in FIG. 1 is used for forming the groove cover 1 (see FIG. 6) of the side groove. The mold A includes a box frame 51 that can be opened and closed, a steel plate partition plate 55 assembled to the box frame 51, and a mounting hole forming member 7 provided in the partition plate 55. The formwork body 5 is formed by the formwork 51 and the partition plate 55, and the attachment hole forming member 7 is attached to the partition plate 55 as an attachment. In the example shown in the drawing, the inner space of the box-shaped frame 51 is divided into a plurality of partitions in one direction by a plurality of partition plates 55 so that a plurality of groove lids 1 are formed in a single molding step. However, this point can also be configured such that one groove cover body 1 is formed in one molding step by using one partition plate 55 and a narrow box-shaped frame 51. It is. In any case, one side plate of the box-shaped frame 51 can be used as a partition plate. In the illustrated example, one side plate of the box-shaped frame 51 is used instead as a partition plate.

  In the above-mentioned mold A, the surface of the partition plate 55 forms a molding surface 56 for molding the lower surface 1a (see FIG. 6) of the groove lid body 1. On the other hand, as shown in FIG. 2, the mounting hole forming member 7 has an outer surface shape made of a truncated cone rubber, and a magnet 71 as a coupling means is embedded in the bottom of the wide side. The surface of the magnet 71 is exposed on the bottom surface of the mounting hole forming member 7.

After the heat curing is completed and the molding of the groove lid body 1 is completed, a mold release step is performed as shown in FIG. In FIG. 4, mold release is performed by opening the partition plate 55 substituted for the side plate of the box-shaped frame 51 (see FIG. 1) as indicated by an arrow. In addition, the mounting hole forming member 7 is released from the groove lid body 1 together with the partition plate 55 while adsorbed to the partition plate 55. This is because the magnet 71 of the mounting hole forming member 7 is attracted to the partition plate 55 made of steel plate and the outer surface shape of the mounting hole forming member 7 is a truncated cone. Therefore, only the trace of the mounting hole forming member 7 remains as shown in FIG. 4, and the mounting hole forming member 7 itself does not remain in the molded groove lid 1 that has been released. This trace is the mounting hole 12 itself. A rubber cushioning material 9 is attached to the attachment hole 12 as shown in FIG. In order to leave the mounting hole forming member 7 on the partition plate 55 side by releasing, for example, the mounting hole forming member 7 has a height of about 9 mm, a bottom surface diameter of about 44 mm, and a top surface diameter of about 41 mm. It is good to set in.

  As shown in FIG. 7, the shape of the mounting hole 12 formed in the groove lid body 1 after molding is the same as the shape of the outer surface of the mounting hole forming member 7. Therefore, the attachment hole 12 has a shape that becomes narrower as it is closer to the hole bottom, and more specifically, has a circular hole shape that becomes smaller in diameter as it gets closer to the hole bottom. On the other hand, the cushioning material 9 is provided with a tapered insertion portion 91 having a tapered shape as can be seen in FIG. 9, and only by inserting the convex insertion portion 91 into the mounting hole 12 of the groove lid body 1. , Attached to the groove lid 1.
