Description

本発明は、締緩工具に装着されるソケットに関し、特にコンクリート構造物にインサートを埋設する作業の一環として、型枠にインサートを取り付ける取付用治具をコンクリート硬化後に取り外す際に使用される。 The present invention relates to a socket to be mounted on a tightening tool, and is particularly used when removing a mounting jig for attaching an insert to a formwork after the concrete has hardened, as part of the work of embedding the insert in a concrete structure.

周知のようにコンクリート構造物、例えばトンネルやボックスカルバートのコンクリート壁・天井などにはセラミック製のインサートが埋設され、該インサートに所望の被固定部材が締結されている。 As is well known, a ceramic insert is embedded in a concrete structure, for example, a concrete wall / ceiling of a tunnel or a box culvert, and a desired fixed member is fastened to the insert.

図９に基づき概略を説明すれば、インサート１は雌ねじ孔２を有するインサート本体３と、雌ねじ孔２に連通する連通孔４ａ，４ｂが軸方向に形成されたスリーブ５ａ，５ｂとを備え、プラスチックホルダ（取付用治具）８により型枠６に着脱自在に取り付けられている。 To explain the outline based on FIG. 9, the insert 1 includes an insert body 3 having a female screw hole 2 and sleeves 5a and 5b in which communication holes 4a and 4b communicating with the female screw hole 2 are formed in the axial direction, and is made of plastic. It is detachably attached to the mold 6 by a holder (attachment jig) 8.

このプラスチックホルダ８は、一端部に形成された雄ねじ部９と、他端部に形成されたストッパー１０と、を備える。このストッパー１０は、弾性変形可能な一対のストッパー片１０ａと、最先端１０ｂに形成されたプラスチックホルダ８の抜脱用のナット穴１０ｃと、を備えている。このナット穴１０ｃは、横断面六角形状の六角穴に形成され、図示省略の六角レンチの端部が嵌入可能となっている。 The plastic holder 8 includes a male screw portion 9 formed at one end and a stopper 10 formed at the other end. The stopper 10 includes a pair of elastically deformable stopper pieces 10a and a nut hole 10c for removing and removing the plastic holder 8 formed at the cutting edge 10b. The nut hole 10c is formed in a hexagonal hole having a hexagonal cross section, and an end portion of a hexagon wrench (not shown) can be fitted.

そして、インサート１の埋設時には、雄ねじ部９を連通孔４ａ，４ｂに通して雌ねじ孔２に螺入させた後に頭部１０を取付孔７に挿通する。その後に型枠６内にコンクリートを打設し、コンクリート硬化後にナット穴１０ｃに前記六角レンチの端部を嵌入させる。この状態のまま前記六角レンチを回転させて両者２，９の締結を緩め、プラスチックホルダ８を取り外す。 Then, when the insert 1 is embedded, the male screw portion 9 is passed through the communication holes 4a and 4b and screwed into the female screw hole 2, and then the head 10 is inserted into the mounting hole 7. After that, concrete is poured into the mold 6, and after the concrete is hardened, the end portion of the hexagon wrench is fitted into the nut hole 10c. In this state, rotate the hexagon wrench to loosen the fastening of both 2 and 9, and remove the plastic holder 8.

特開２００３−２７５９７Japanese Patent Application Laid-Open No. 2003-27597

確かに特許文献１によれば、ナット穴１０ｃに前記六角レンチの端部を嵌入させて回転させれば、プラスチックホルダ８を取り外すことは可能である。 Certainly, according to Patent Document 1, the plastic holder 8 can be removed by fitting the end of the hexagon wrench into the nut hole 10c and rotating it.

しかしながら、プラスチックホルダ８を取り出す際にナット穴１０ｃを滑めてしまう事態が想定される。この場合、ナット穴１０ｃの六角の部分が削られて変形するため、その後はプラスチックホルダ８の取り外しができないおそれがある。 However, it is assumed that the nut hole 10c slips when the plastic holder 8 is taken out. In this case, since the hexagonal portion of the nut hole 10c is scraped and deformed, the plastic holder 8 may not be removed thereafter.

本発明は、このような問題を解決するためになされ、インサートから取付用治具を確実に取外し可能な工具の提供を解決課題としている。 The present invention has been made to solve such a problem, and an object of the present invention is to provide a tool capable of reliably removing a mounting jig from an insert.

It is characterized by including an inlet and an engaging portion that engages with the engaged portion formed in the mounting jig.

例えば前記取付用治具は、前記インサートの雌ねじ穴に締結される雄ねじ部と、前記インサートを型枠に取り付ける頭部と、該両部間のフランジ部と、該フランジ部に形成された前記被係合部と、を備える。このとき締緩工具用ソケットは、前記頭部を収容する収容口をさらに備える。なお、前記係合部は、前記収容口の開口端部に設けることが好ましい。 For example, the mounting jig includes a male screw portion to be fastened to a female screw hole of the insert, a head for mounting the insert to a mold, a flange portion between the two portions, and a covering formed on the flange portion. It is provided with an engaging portion. At this time, the socket for the tightening / loosening tool further includes a storage port for accommodating the head. It is preferable that the engaging portion is provided at the open end portion of the accommodating port.

前記被係合部および前記係合部の一態様としては、前記被係合部を係合孔部として形成する一方、前記係合部を前記係合孔部に嵌入可能な係合突起として形成することができる。この場合に複数の前記係合孔部を前記フランジ部に形成し、前記開口端部の前記各係合孔部に応じた位置に前記係合突起をそれぞれ形成することが好ましい。 In one aspect of the engaged portion and the engaged portion, the engaged portion is formed as an engaging hole portion, while the engaging portion is formed as an engaging projection that can be fitted into the engaging hole portion. can do. In this case, it is preferable to form a plurality of the engaging holes in the flange and to form the engaging protrusions at positions corresponding to the engaging holes in the opening end.

その際は、収容口３３ａを頭部２２と対向させるとともに、各係合突起３４を各係合孔部３０に対向させる。この対向状態のままソケットレンチを図６（ｈ）の矢印Ｈ方向に移動させれば、収容口３３ａ内に頭部２２が収容され、各係合突起３４が各係合孔部３０に嵌入する。 In that case, the accommodating port 33a faces the head 22, and the engaging protrusions 34 face each engaging hole 30. If the socket wrench is moved in the direction of the arrow H in FIG. 6H in this facing state, the head 22 is accommodated in the accommodating opening 33a, and each engaging protrusion 34 is fitted into each engaging hole portion 30. ..

これにより係合孔部３０の内周に係合突起３４が係合し、両者１１，３１が接続される。ここで使用されるソケットレンチ５０は市販品でよいので、工事にあたって最小限の専用工具、即ち締緩工具用ソケット３１を購入するだけでよく、この点でコストの抑制に貢献できる。 As a result, the engaging projection 34 engages with the inner circumference of the engaging hole portion 30, and both 11 and 31 are connected. Since the socket wrench 50 used here may be a commercially available product, it is only necessary to purchase a minimum dedicated tool, that is, a socket 31 for a tightening / loosening tool, which can contribute to cost reduction.

この接続後にソケットレンチ５０を図６（ｉ）の矢印Ｉ方向に回転させ、雄ねじ部２３ａと雌ねじ穴１５との締結を緩める。これにより雄ねじ部２３ａが雌ねじ穴１５から螺出し、図６（ｊ）の矢印Ｊに示すように、取付用治具１１がインサート１２から抜脱され、インサート１２がコンクリート３２に埋設される。 After this connection, the socket wrench 50 is rotated in the direction of arrow I in FIG. 6 (i) to loosen the fastening between the male screw portion 23a and the female screw hole 15. As a result, the male screw portion 23a is screwed out from the female screw hole 15, the mounting jig 11 is pulled out from the insert 12 and the insert 12 is embedded in the concrete 32 as shown by the arrow J in FIG. 6 (j).

このとき係合孔部３０および係合突起３４は、特許文献１のナット穴１０ｃのように滑めるおそれがなく、インサート１２から取付用治具１１を確実に取り外すことができ、この点で工事の作業性向上に貢献できる。 At this time, the engaging hole portion 30 and the engaging protrusion 34 do not have a risk of slipping unlike the nut hole 10c of Patent Document 1, and the mounting jig 11 can be reliably removed from the insert 12, and at this point. It can contribute to improving the workability of construction.

特に係合孔部３０と係合突起３４とは、それぞれ複数個が形成されているため、その一部が破損しても両者１１，３１を接続して回転させることができる。したがって、締緩工具用ソケット３１を利用すれば、係合孔部３０群の一部に破損があったとしても、取付用治具１１を再利用することが可能である。 In particular, since a plurality of engaging holes 30 and engaging protrusions 34 are formed, even if a part of the engaging holes 30 and the engaging protrusions 34 are damaged, both 11 and 31 can be connected and rotated. Therefore, if the tightening / loosening tool socket 31 is used, the mounting jig 11 can be reused even if a part of the engaging hole portion 30 group is damaged.

なお、取付用治具１１の抜脱後は、インサート本体１４の雌ねじ穴１５に足場ボルトなどの所望の被固定部材が締結される。 After the mounting jig 11 is removed and removed, a desired fixed member such as a scaffolding bolt is fastened to the female screw hole 15 of the insert body 14.
