Description
【０００１】[0001]
この考案は，建設工事において、型枠支保工に用いる大引受金具に、砂ジャッ キ機能を持たせる金具に関するものである。 This invention relates to a metal fitting that has a sand jacking function for a large metal fitting used for supporting a formwork in construction work.
【０００２】[0002]
従来，型枠支保工に用いる大引受金具は、大引材がジャッキ頭部より外れたり 、すべり落ちたりするのを防ぐために、ジャッキ頭部に載せ用いられているだけ である。−図４。 Conventionally, large undertakings used for formwork support are merely mounted on the jack head to prevent the large material from slipping off the jack head or slipping off. FIG.
【０００３】[0003]
これには次のような欠点がある。 （１）、型枠支保工を解体する時は、大引受金具の下のジャッキネジ部を廻して 支保工を下げ、型枠材を引き出し解体するのであるが、−図５、型枠支保工には 、部分的に多大な重量がかかっていたり、偏心荷重がかかっていたりする為に、 ジャッキネジ部がスムーズに廻らず、支保工を下げ、解体する作業に多大な労力 や時間が費やされている。 （２）、ジャッキネジ部が簡単に廻らない為に、従事する作業員により、無理に ジャッキネジ部をハンマー等で叩いて廻したりする行為が為され、ジャッキネジ 部を壊すなどして、ジャッキを利しての解体作業が不能となる事態も多々、発生 している。−図６ 本考案は、以上の欠点を解決する為になされたものである。 This has the following disadvantages. (1) When dismantling the formwork support, the jackscrew part under the large undertaking fitting is turned to lower the support, and the form material is pulled out and dismantled. Since the jack screw part does not turn smoothly due to heavy weight or eccentric load in some parts, it takes a lot of labor and time to lower the support and dismantle. Have been. (2) In order to prevent the jack screw from turning easily, the worker engaged in the operation forced the jack screw to be turned by hitting it with a hammer or the like. In many cases, disassembly work that makes it impossible to do so has become impossible. FIG. 6 The present invention has been made to solve the above drawbacks.
【０００４】[0004]
鉄板（１）の両端に穴（２）を設け、片面にゴム板（３）を貼りつける。 それから、大引受金具（６）の開口面、両面に、鉄板（１）をそれぞれゴム板 （３）が内側になる様にあてがう。 穴（２）にボルト（４）を通し、ナット（５）にて締めつけ、鉄板（１）と大 引受金具（６）を一体化する。これで大引受金具は箱型構造となる。−図３この 箱型構造となった部分に、砂（７）を詰め均等に均す。−図１ 又、ゴム板（３）がパッキンとなり、砂は箱型構造から出ることはない。 この砂を入れた大引受金具を従来の如くジャキに載せ使用する。 支保工解体時、ジャッキのネジ部が廻らない時には、この大引受金具に取りつ けた鉄板（１）を取りはずし、中の砂を取り除けば、支保工は砂の厚み分だけ下 がり、解体作業を容易に行う事ができる。 本考案は以上の如く、大引受金具に砂ジャッキ機能を持たせる事を特徴とした 、金具である。 Holes (2) are provided at both ends of the iron plate (1), and a rubber plate (3) is attached to one side. Then, the iron plate (1) is applied to the opening surface and both surfaces of the large undertaking metal fitting (6) such that the rubber plate (3) is inside. Pass the bolt (4) through the hole (2) and tighten it with the nut (5) to integrate the iron plate (1) with the large metal fitting (6). Thus, the large undertaking has a box-shaped structure. -Fig. 3 Sand (7) is filled in the box-shaped structure and evenly distributed. -Fig. 1 Also, the rubber plate (3) serves as a packing, so that sand does not come out of the box-shaped structure. The large metal fittings containing the sand are placed on a jack and used as before. If the screw of the jack does not turn when the support is dismantled, remove the iron plate (1) attached to this large underpatch and remove the sand inside, and the support will go down by the thickness of the sand, and the dismantling work will be completed. It can be done easily. As described above, the present invention is a metal fitting characterized by having a sand jacking function in a large undertaking metal fitting.

本考案を使用する時には、大引受金具（６）にゴム板（３）を貼りつけた鉄板 （１）をボルト、ナットにて締めつけ固定し、箱型構造となし、それに砂を入れ て従来の大引受金具同様、ジャッキの上に載せ使用する。そして支保工の解体作 業の際、ジャッキネジ部が廻りにくい時には、この鉄板（１）を取り除き、中の 砂を取り除く事により支保工を下げ、解体作業を容易にするのである。 When using the present invention, the steel plate (1) with the rubber plate (3) attached to the large undertaking (6) is tightened and fixed with bolts and nuts to form a box-shaped structure. It is used on the jack as well as the large underpatch. If the jack screw is difficult to turn during the demolition work of the shoring, the iron plate (1) is removed and the sand inside is removed to lower the shoring and facilitate the demolition work.
【０００６】[0006]
以下、本考案の実施例を述べる。 （イ）、鉄板（１）の両端にボルトを通す穴（２）を設ける。 （ロ）、その鉄板の片面にゴム板（３）を貼りつける。 （ハ）、大引受金具（６）の開口面両面に、鉄板（１）をゴム板（３）が内側に なるようにあてがう。 （ニ）、ボルト（４）を鉄板の穴（２）に通しナット（５）にて締めつけ、大引 受金具（６）と鉄板（１）を一体化し箱型構造となす。 （ホ）、その中に砂（７）を入れ均等に均す。 （ヘ）ゴム板（３）がパッキンとなり、砂は箱型構造から出ることはない。 本考案は以上の構成よりなっている。 本考案を使用する時は、以上の如く構成したもの−図１を、従来の大引受金具 を使用していたように、ジャッキの上に載せて使用する。 そして支保工を解体する際、ジャッキが容易に下げられない場合は、金具を取り はずして中の砂を取り除く。砂を取り除く事により、砂の厚さ分、支保工を下げ る事ができ、解体作業を容易に行うことができる。 通常支保工を下げる作業においては、下げ始めの１〜３センチメートルの間に 、相当の荷重がかかっており、この間を下げるのが困難なのであるが、この間、 砂ジャッキを用いて下げることにより、多大な省力化を成すことができる。 又、金具自体も簡単に工作でき、取りつけ撤去の作業も、ボルト締めとなって いるので手間が掛からず、簡単に行える。 Hereinafter, embodiments of the present invention will be described. (A), holes (2) for passing bolts are provided at both ends of the iron plate (1). (B) A rubber plate (3) is attached to one side of the iron plate. (C) Apply the iron plate (1) to both sides of the opening surface of the large undertaking bracket (6) such that the rubber plate (3) is inside. (D) Pass the bolt (4) through the hole (2) in the steel plate and tighten it with the nut (5). The large metal fitting (6) and the steel plate (1) are integrated to form a box-type structure. (E) Put sand (7) into it and level it evenly. (F) The rubber plate (3) serves as packing, and sand does not come out of the box-shaped structure. The present invention has the above configuration. When the present invention is used, the above-configured one shown in FIG. 1 is placed on a jack, as in the case of using the conventional large undertaking. If the jack cannot be easily lowered when dismantling the shoring, remove the metal fittings and remove the sand inside. By removing the sand, the support work can be reduced by the thickness of the sand, and the demolition work can be performed easily. Usually, in the work of lowering the shoring, a considerable load is applied during the first 1 to 3 cm of lowering, and it is difficult to lower during this time, but during this time, by lowering with a sand jack, Great labor savings can be achieved. In addition, the hardware itself can be easily machined, and the mounting and removing work can be easily performed without bolts because it is bolted.
