Description

本発明は鋼製パネルから成るコンクリート型枠工事等に使用する釘抜き付きハンマーに関するものである。   The present invention relates to a hammer with a nail punch for use in concrete formwork made of steel panels.

従来、この種のハンマーは、一方に釘の打叩面を形成した打叩部と他方に釘の頭部を掛止して引き抜き可能な略Ｖ字溝状の釘抜き部とを一体に形成したハンマー頭部と、該ハンマー頭部に固着した柄部とからなるものが一般的であった。コンクリート打設工事は型枠組立作業、コンクリート打設、脱型作業を繰り返して行うが、型枠などにコンクリートノロが付着する。それらのノロは組立作業前にケレン棒を使用して清掃作業をしていた。また、鋼型パネル使用の型枠工事においても脱型作業は、バールにて、接続クリップボルトを解除してケレン棒を使用して型枠の清掃作業をしていた。この問題に対し、特開２０００−１９０２５３号には、ハンマー打叩部の側面にコンクリートノロを削り落とす突出片を形成した考案が提案されている。   Conventionally, this type of hammer is integrally formed with a hitting portion in which a hitting surface of a nail is formed on one side and a substantially V-shaped nail extraction portion that can be pulled out by hooking the head of the nail on the other side. Generally, a hammer head and a handle fixed to the hammer head are used. Concrete placement work is performed by repeatedly performing formwork assembly work, concrete placement work, and mold removal work, but concrete sticks to the formwork and the like. These blades were cleaned using keren rods before assembly. Also, in the formwork construction using the steel panel, the demolding work was done by releasing the connecting clip bolt and cleaning the formwork using the keren rod at the bar. In order to solve this problem, Japanese Patent Application Laid-Open No. 2000-190253 proposes a device in which a protruding piece is formed on the side surface of the hammer hitting portion to scrape off the concrete blade.

特開２０００−１９０２５３号公報JP 2000-190253 A

しかし上記のハンマーでは、コンクリートノロを取り除くことは可能であるが鋼製パネルのコンクリート型枠脱型時においては、該ハンマーは何の効果を奏するものではなく、単にハンマーの機能を有するのみである。従って、ハンマーとは別にバールを常時携帯する必要があった。
本発明は、釘の打ち込み不要な釘の引き抜きができると共にコンクリートノロも取除くことができ、鋼製パネルの接続クリップボルトの解除にも兼用できるハンマーを提供することを目的とするものである。 However, with the above-mentioned hammer, it is possible to remove the concrete paste, but when the steel panel is removed from the concrete formwork, the hammer does not have any effect and merely has the function of a hammer. . Therefore, it was necessary to always carry the bar separately from the hammer.
SUMMARY OF THE INVENTION An object of the present invention is to provide a hammer that can pull out a nail that does not need to be driven into a nail and can also remove a concrete chip, and can also be used to release a connection clip bolt of a steel panel.

釘の打叩部と打叩部の反対側を外側に向けて傾斜したをハンマー頭部と該ハンマー頭部の底面に固着した柄部からなるハンマーにおいて鋼製パネルの接続クリップボルト解除用の係合部をハンマー頭部に形成したことを特徴とするハンマーを使用するものである。   A member for releasing a connection clip bolt of a steel panel in a hammer having a hammer head and a handle portion fixed to the bottom surface of the hammer head which is inclined with the opposite side of the nail hitting portion facing outward. A hammer characterized by forming a joint on the hammer head is used.

上記のとおり、本発明によるハンマーによれば、鋼製パネルの型枠に付着したコンクリートノロを容易に削ぎ落すことが可能であるとともに、コンクリート打設後の脱型作業においても、接続クリップボルトを簡単に脱すことが可能となり、該ハンマー１本でこれらの作業を行うことができるようになった。
またハンマー頭部の打叩部反対側を外方に傾斜させたので、頭部頂面を大きくすることができ、コンクリートノロを容易にしかも短時間に削ぎ落とすことが可能になった。 As described above, according to the hammer of the present invention, it is possible to easily scrape off the concrete stick attached to the formwork of the steel panel, and the connection clip bolt is also used in the demolding work after the concrete is placed. It can be easily removed, and these operations can be performed with one hammer.
Moreover, since the opposite side of the hammer head to the hitting portion is inclined outward, the top surface of the head can be enlarged, and the concrete nose can be easily scraped off in a short time.

以下、本発明による最良の実施例を図面に基づいて詳細に説明する。図１は本発明の実施例を示す斜視図、図２は本発明の実施例の斜視図、図３および図４は本発明によるハンマーの使用状態を示す概略図である。
１はハンマー頭部であり、該ハンマー頭部１は打叩部２と他方のケレン刃部３とから構成されている。４はそのハンマー頭部１の底面に固着した柄部である。

ハンマー頭部１の中央の柄部４とは反対側に接続クリップボルト１０に係合する係合部７を設けている。さらに、ハンマー頭部１の柄部４側のケレン刃部３と柄部４の間に係合部６を設けている。図４に示すようにケレン刃部３を下方に向けて鋼製パネル９のクリップボルト１０にハンマー頭部１の係合部６、７が合うように当てる。それから矢印方向に持ち上げるように回動し、接続クリップボルト１０を鋼製パネル９より解除する。
クリップボルト１０とハンマー頭部１の係合部６、７が所定の位置よりもずれていても係合部７は溝部もしくは突部になっており、はずれることなくハンマー１を持ちあげるとクリップボルト１０を解除できる。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view of the embodiment of the present invention, and FIGS. 3 and 4 are schematic views showing a usage state of the hammer according to the present invention.
Reference numeral 1 denotes a hammer head, and the hammer head 1 includes a hitting portion 2 and the other keren blade portion 3. A handle 4 is fixed to the bottom surface of the hammer head 1.

An engaging portion 7 that engages with the connection clip bolt 10 is provided on the opposite side of the central handle portion 4 of the hammer head 1. Further, an engaging portion 6 is provided between the keren blade portion 3 and the handle portion 4 on the handle portion 4 side of the hammer head 1. As shown in FIG. 4, the keren blade 3 is directed downward so that the engaging portions 6 and 7 of the hammer head 1 are brought into contact with the clip bolt 10 of the steel panel 9. Then, it is rotated so as to be lifted in the direction of the arrow, and the connection clip bolt 10 is released from the steel panel 9.
Even if the engaging portions 6 and 7 of the clip bolt 10 and the hammer head 1 are deviated from a predetermined position, the engaging portion 7 is a groove or a protrusion, and if the hammer 1 is lifted without being disengaged, the clip bolt 10 can be released.

鋼製パネル９での型枠組立においては、パネル同士つなぐ場合、片方のパネルの側面の穴部に片方のクリップボルト１０がついたパネルを合わせ、クリップボルト１０を穴部に貫通させる。それからパネル側面部が合うようにクリップボルト１０を上からハンマーで打叩して締め込む。
鋼製パネル９の型枠解体においては、ハンマーのケレン刃部３を下に向けて、鋼製パネル９のクリップボルト１０にハンマー頭部１の係合部６、７を合うように当てて、上方へ持ち上げる。
また、鋼製パネル９のクリップボルト１０側の空間に土、もしくは障害物があって、図４のようにハンマーをクリップボルト１０にハンマーの係合部６、７を合うように当てることができない場合、図３のようにバール部８をクリップボルト１０に掛けて矢印の方向へ押し付けると解除できる。 In the formwork assembly with the steel panel 9, when connecting the panels, the panel with one clip bolt 10 is aligned with the hole on the side of one panel, and the clip bolt 10 is passed through the hole. Then, the clip bolt 10 is struck with a hammer from the top so that the side surfaces of the panel are aligned.
In dismantling the form of the steel panel 9, the hammer's Keren blade part 3 is faced down and the engaging parts 6 and 7 of the hammer head 1 are applied to the clip bolt 10 of the steel panel 9 so as to fit, Lift up.
Further, there is dirt or an obstacle in the space of the steel panel 9 on the clip bolt 10 side, and the hammer cannot be applied to the clip bolt 10 so that the engaging portions 6 and 7 of the hammer are fitted to each other as shown in FIG. In this case, as shown in FIG. 3, the bar portion 8 is hung on the clip bolt 10 and pressed in the direction of the arrow to be released.

また係合部６、７の形状について図７に示すようなものでも良い。   Further, the shape of the engaging portions 6 and 7 may be as shown in FIG.
