As shown in FIG. 2, concrete 2 is cast between the dams 1, and the dam 1 is used to hold the dams 1 at a predetermined interval.
The space is joined by the separator 3.

スチック製のコーン４をセパレータ３の端部に結合し、
脱型時にせき板１とともにコーン４も除去する。In this case, when the surface of the concrete 2 after demolding becomes a bare surface, a wooden or plastic cone 4 is attached to the end of the separator 3 so that the end of the separator 3 does not protrude from the surface of the concrete 2. Joined to the department,
At the time of removal from the mold, the cone 4 is also removed together with the dam 1.

は無収縮性のモルタルで跡埋め処理を行っている。[0004] The hole from which the cone 4 has been removed after the demolding is filled with mortar or the like in order to prevent the separator 3 from rusting and prevent water from leaking into the concrete 2. In buildings, mortar moldings are embedded in cone traces using adhesives in consideration of waterproofness and beauty of the exposed surface, but in civil engineering structures, compared to buildings in general,
Since the cones are large and large in number, the mortar or non-shrinkable mortar is used to fill the traces.

【発明が解決しようとする課題】特に自然環境に暴露さ
れやすい構造物において、モルタルで跡埋め処理を行う
場合は、跡埋めしたモルタルの収縮、セパレータネジ部
の腐食膨張等が原因で、跡埋め材の剥離、落下が発生し
やすい。In a case where a mortar is used to fill a trace in a structure which is easily exposed to the natural environment, the trace fill may be caused due to shrinkage of the mortar filled, erosion of a separator screw portion, and the like. Peeling and falling of the material easily occur.
【０００６】かかる跡埋め材の剥離、落下を防止するに
は、跡埋め材の材質を高品質のものにし、無収縮で接着
性の高いものを使用すればよいが、コスト高となる。In order to prevent the trace filling material from peeling and falling, it is sufficient to use a high quality material for the trace filling material and use a non-shrinkable material having high adhesiveness, but this increases the cost.
【０００７】本発明の目的は前記従来例の不都合を解消

ジのピッチに同期させたことを要旨とするものである。According to the present invention, in order to achieve the above-mentioned object, a concrete formwork is attached to an end of a separator. The main body is formed in a truncated conical megaphone shape. A screw hole for coupling is provided, and in the cone in which a screw is formed by a spiral groove in the screw hole, an uneven portion is formed on the outer peripheral surface of the main body so that an uneven portion is formed on the inner surface of the cone hole after removing the mold. The gist of the present invention is that a spiral projection is formed so as to project, and the pitch of the spiral projection is synchronized with the pitch of the screw in the screw hole.

だモルタルは、この凹部に入り込むから、収縮しても穴
から落下しない。According to the present invention, the concave and convex portions formed on the outer peripheral surface of the cone body form the concave and convex portions in the hole formed on the concrete surface after demolding. Therefore, the mortar embedded in the hole enters the recess, and does not fall from the hole even when contracted.

By making the pitch of the spiral projection the same as the pitch of the screw formed on the cone body, removal of the cone from the separator is not hindered.

きってある。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a cone according to the present invention. A cone 4 according to the present invention is attached to an end of a separator 3 in a concrete formwork as already known with reference to FIG. The main body 4a is made of wood or plastic and is formed in the shape of a truncated cone megaphone, and a screw hole 5 for coupling to the separator 3 is provided at the center on the small diameter side. It is.

り、本体４ａの外周面に凹凸部を形成する。In the cone 4, a helical projection 6 is integrally provided on the outer peripheral surface of the main body 4a.
Is synchronized with that of the screw 5a. Thereby, an uneven portion is formed on the outer peripheral surface of the main body 4a.

去を妨げることにはならず、容易に抜ける。As described above, in order to remove the cone 4 from the separator 3 after the mold has been released, the cone 4 can be pulled out by rotating the cone. At this time, since the pitch of the spiral projection 6 and the pitch of the screw 5a are formed to be the same, even if the spiral projection 6 is newly provided, this does not hinder the removal of the cone 4 from the separator 3 and is easy. Exit.

下することはない。Since the spiral groove is formed on the inner surface of the hole after removing the cone 4 by the spiral protrusion 6, if the mortar is embedded in the hole, the mortar enters the spiral groove. Therefore, even if shrinkage occurs in the mortar after that, the mortar does not drop because the mortar fills the groove.

である。As described above, the corn of the present invention can be used even when a cheap and shrinkable mortar is used for the mortar filling mortar.
The mortar can prevent the mortar from dropping and peeling, and especially when used on roads or structures adjacent to public amenities, it can prevent the cone from falling and can ensure safety.
