Description

本考案は、コンクリート型枠工事における組立時から解体時までの作業を、効率的に行なうことができる型枠工事用金槌に関するものである。  The present invention relates to a metal mold for formwork that can efficiently perform operations from assembly to dismantling in concrete formwork.

従来、型枠用金槌は片方に首の長い金槌部と反対側に釘抜き部を持つもので、釘打ちと釘抜きを一つの道具で出来るようになっている。コンパネ等に釘を打ち込む際は、打ち込み部位に釘の先端を突き刺すまでは、一方の手に金槌の柄を持ち、他方の手で釘を支えて釘を位置決めするため、両方の手を使って打ち込み作業を行っている。また、作業中や解体時にコンパネ及び桟木に付着したコンクリートを除去しなければならない時、除去するのに適した道具(例えば、ケレン棒)を使用するのが面倒である為、金槌部で叩いて除去するのが一般的である。  Conventionally, a metal mold for molds has a long metal neck on one side and a nail punch on the opposite side, so that nailing and punching can be performed with a single tool. When driving a nail into a control panel, etc., hold the handle of the hammer in one hand and position the nail with the other hand until you pierce the tip of the nail. I'm working on driving. Also, when it is necessary to remove the concrete attached to the control panel and pier during work or dismantling, it is troublesome to use a tool suitable for removal (for example, a keren rod). It is common to remove.

このような作業を改善するために、様々な工夫がなされている。例えば、釘頭を打面に磁着させることによって片手で釘を打てる金槌が開示されている(特許文献1、特許文献2参照。)。また、釘打ち作業およびコンクリート固化物除去作業ができ、コンクリート固化物除去作業による槌頭上面部分の磨耗が小さくて長寿命であるとされる金槌が開示されている(特許文献3参照。)。  Various improvements have been made to improve such work. For example, a hammer that can be nailed with one hand by magnetically attaching a nail head to a striking surface is disclosed (see Patent Document 1 and Patent Document 2). Further, a hammer that is capable of performing a nailing operation and a concrete solidified material removing operation, and has a small wear on the upper surface of the wharf due to the concrete solidified material removing operation and having a long life is disclosed (see Patent Document 3).

特許文献1及び2に開示されている金槌は、釘を打ち付ける打面に磁石を埋設したものであり、打面に釘頭を磁着させ、釘を起立させて、打ち込み部位に釘の先端を位置させ、磁石を配置した打面で叩いて釘の先端を突き刺し、そのまま、磁石を埋設した打面で、突き刺した釘を強く叩き、釘を打ち込んでゆくものである。しかしながら、打面に磁石を埋設することで強度が低下し、釘頭を金槌の打面で繰り返し強く叩くと、打面が損傷して使用できなくなるという問題があった。  The hammers disclosed in Patent Documents 1 and 2 are magnets embedded in the striking surface for hitting the nail, the nail head is magnetized on the striking surface, the nail is raised, and the tip of the nail is placed at the driving site. The nail is struck by hitting with the striking surface on which the magnet is placed, and the tip of the nail is stabbed, and the stabbed nail is struck with the striking surface with the magnet embedded, and the nail is driven. However, the strength is lowered by embedding a magnet in the striking surface, and there is a problem that when the nail head is repeatedly hit with a hammering surface repeatedly, the striking surface is damaged and cannot be used.

また、特許文献3に開示されている金槌は、槌頭の上面をコンクリート固化物よりも硬い硬質板体を有する集合板体で被覆した構成にしており、該集合板体は槌頭とは別個独立に構成され、槌頭の上面にビスで着脱自在に取り付けられている。この金槌によれば、ケレン掛けの作業者が金槌の柄を手で持ち、解体後の型枠材料の表面に残ったコンクリート固化物を槌頭の上面で柄の軸心方向に押して剥ぎ取っていくことができる。しかしながら、この構造では槌頭の長さ(打面から釘抜き部までの長さ)以上の幅がある場所のケレン掛けしかできず、狭隘な場所のケレン掛けはできないという問題があった。  Further, the metal hammer disclosed in Patent Document 3 has a structure in which the upper surface of the wharf is covered with a collective plate having a hard plate harder than a concrete solidified material, and the collective plate is separated from the wharf. It is configured independently and is detachably attached to the upper surface of the wharf with screws. According to this hammer, the worker who hangs the kettle with the handle of the hammer, presses the concrete solid material remaining on the surface of the formwork material after dismantling and pushes it off in the axial direction of the handle on the upper surface of the pier. I can go. However, this structure has a problem that it can only be applied to a part having a width equal to or greater than the length of the wharf (the length from the hitting surface to the nail extraction part), and cannot be applied to a narrow part.

本考案は、上記問題を解決するためになされたものであり、釘打ち及びケレン掛け作業を効率的に行なう型枠工事用金槌(以下、金槌という)を提供するものである。  The present invention has been made to solve the above-described problems, and provides a formwork work hammer (hereinafter referred to as a metal hammer) that efficiently performs nailing and keren-hanging operations.

本考案の金槌は、釘を打つ槌頭に柄が取り付けられている金槌において、前記槌頭近傍の柄部の両面に円筒状の磁石を埋設し、該磁石を保護する略コ字形の磁石保護体で、前記磁石を保護したことを特徴としている。このように構成すれば、金槌の柄を片手で把持し、磁石に釘頭を磁着させた状態でコンパネ等に仮止めし、次に金槌の打面で釘を打ち込むことで、連続した作業が可能となり、作業効率が向上する。  The hammer of the present invention is a hammer with a handle attached to a pier where a nail is struck, and a cylindrical magnet is embedded on both sides of the handle near the pier to protect the magnet. The magnet is protected by a body. If comprised in this way, the handle of the hammer is held with one hand, the nail head is magnetically attached to the magnet, and then temporarily fixed to the control panel, etc. Work efficiency is improved.

また、本考案の金槌は、前記槌頭の釘打ち部の打面が、槌頭の長手方向が長辺となる楕円形又は長円形に形成されていることを特徴としている。このように構成すれば、槌頭の打面を形成する楕円形又は長円形の短辺幅以上の隙間があれば、コンパネ等に付着したコンクリート付着物のケレン掛けを、金槌の打面で行なうことができるので、作業効率が向上する。  The hammer of the present invention is characterized in that the hitting surface of the nailed portion of the pier is formed in an oval shape or an oval shape having a long side in the longitudinal direction of the pier. If comprised in this way, if there is a gap more than the short side width of the ellipse or oval which forms the hitting surface of the wharf, the concrete adhesion adhering to the control panel etc. will be applied with the hammering surface of the hammer. Work efficiency is improved.

本考案の金槌は、槌頭近傍の柄部の両面に磁石が取り付けられている。また、前記槌頭の釘打ち部の打面が、槌頭の長手方向が長辺となる楕円形又は長円形に形成されている。この構成により、金槌の柄を片手で把持し、前記磁石に釘頭を磁着させた状態でコンパネ等に仮止めして金槌の打面で釘を強く打ち込むことができる。また、槌頭の打面を形成する楕円形又は長円形の短辺幅以上の隙間があれば、コンパネ等に付着したコンクリート付着物を打面で押す又は引くことにより、ケレン掛けを行なうことができる。これにより、釘打ちとケレン掛けを同じ金槌で効率的に行なうことができるので、格段に作業効率が向上する。  The hammer of the present invention has magnets attached to both sides of the handle near the wharf. The hitting surface of the nailed portion of the wharf is formed in an elliptical shape or an oval shape having a long side in the longitudinal direction of the wharf. According to this configuration, the handle of the hammer can be gripped with one hand, and the nail can be driven strongly with the hammer hitting surface by temporarily fixing it to the control panel or the like with the nail head magnetically attached to the magnet. In addition, if there is an oval or oval gap with a short side width or more that forms the hitting surface of the wharf, the concrete can adhere to the control panel or the like by pushing or pulling it on the hitting surface. it can. As a result, nailing and keren hanging can be efficiently performed with the same hammer, so that the working efficiency is remarkably improved.

以下、本考案の金槌について、図面を参照して説明する。図1は本考案の一例を示す金槌の正面図であり、図2は、本考案の一例を示す金槌の磁石保護体の斜視図である。図1、図2において、1は金槌、2は槌頭、3は柄、4は磁石、5は磁石保護体である。前記金槌1は、片方に首の長い金槌部21と反対側に釘抜き部22が形成されており、釘打ちと釘抜きを一つの道具で出来るようになっている。磁石4は円板状であるが、円筒状や角状としてもよく、柄3の両側面に嵌入されており、繰り返し強い衝撃を受けると損傷するおそれがあるので、磁石保護体5で保護されている。  Hereinafter, the hammer of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a hammer with an example of the present invention, and FIG. 2 is a perspective view of a magnet protector of the hammer with an example of the present invention. 1 and 2, 1 is a gold hammer, 2 is a wharf, 3 is a handle, 4 is a magnet, and 5 is a magnet protector. The hammer 1 is provided with a nail punch 22 on the opposite side to the hammer 21 having a long neck, so that nailing and punching can be performed with a single tool. The magnet 4 has a disk shape, but may be cylindrical or square, and is fitted on both side surfaces of the handle 3 and may be damaged by repeated strong impacts. Therefore, the magnet 4 is protected by the magnet protector 5. ing.

コンパネ等に釘(図示しない)を打ち込む際は、一方の手に金槌1の柄3を持ち槌頭2の近傍の柄3に設けられた磁石4が位置する磁石保護体5に釘頭を磁着させた状態で、打ち込み部位に釘の先端を軽く突き刺す。この状態で柄3を釘頭から離すと釘はコンパネ等に軽く刺さった状態で立設する。次に、前記釘頭を前記金槌の打面で強く打ち込むと、釘はコンパネ等に打ち込まれる。なお、右手で柄3持つときは釘を左保護部51に磁着し、左手で柄3を持つときは右保護部52に磁着する。  When a nail (not shown) is driven into a control panel or the like, the nail head is magnetized on the magnet protector 5 where the magnet 3 provided on the handle 3 near the wharf 2 is held with the handle 3 of the hammer 1 in one hand. While wearing, lightly pierce the tip of the nail into the driving site. In this state, when the handle 3 is separated from the nail head, the nail is erected in a state where the nail is lightly stuck in a control panel or the like. Next, when the nail head is strongly driven with the hammering surface, the nail is driven into a control panel or the like. When the handle 3 is held with the right hand, the nail is magnetically attached to the left protective portion 51, and when the handle 3 is held with the left hand, the nail is magnetically attached to the right protective portion 52.

図2において、5は磁石保護体、51は左保護部、52は右保護部、53は連結部である。磁石保護体5は強磁石体である鉄板を用いて、左保護部51と右保護部52を連結する連結部53からなる略コ字形に一体形成されており、槌頭近傍の柄部に磁石4を保護するように被着されている。なお、前記磁石保護体5は、コ字形に替えて単独の平板として、夫々の磁石を被着してもよい。  In FIG. 2, 5 is a magnet protector, 51 is a left protector, 52 is a right protector, and 53 is a connecting part. The magnet protector 5 is integrally formed in a substantially U-shape including a connecting portion 53 that connects the left protecting portion 51 and the right protecting portion 52 using an iron plate that is a strong magnet body. 4 is attached to protect. The magnet protector 5 may be attached as a single flat plate instead of the U-shape.

図3は、本考案の一例を示す金槌の打面の正面図であり、(a)は楕円形、(b)は長円形を示したものである。従来の金槌の打面は、首の基部から打面に向かって漸次太くなるように形成されており、打面の形状は円形や八角形である。この形状では狭隘な部分のケレン掛けができないため、本考案では打面を楕円形又は長円形としている。なお長円形とは、図3(b)に示すように、二つの等しい長さの平行線と二つの半円形からなる形状をいう。本考案の金槌の打面は、このように形成されているので、金槌1の柄3を手で持ち、打面23の縁をベニヤ板等の表面と接するよう当接させた状態とし、この縁でコンクリート固化物を押すか又は引くことにより、コンクリート固化物を剥離させることができる。  FIG. 3 is a front view of a hammering surface showing an example of the present invention, wherein (a) shows an oval shape and (b) shows an oval shape. The hitting surface of a conventional hammer is formed so as to gradually become thicker from the base of the neck toward the hitting surface, and the shape of the hitting surface is circular or octagonal. In this shape, it is not possible to squeeze a narrow portion, so that the hitting surface is an ellipse or an oval in the present invention. In addition, as shown in FIG.3 (b), an ellipse means the shape which consists of two parallel lines of equal length, and two semicircles. Since the hammering surface of the hammer of the present invention is formed in this way, the handle 3 of the hammer 1 is held by hand, and the edge of the hammering surface 23 is brought into contact with the surface of a plywood board or the like. The concrete solidified material can be peeled off by pressing or pulling the concrete solidified material.

本考案の金槌は、型枠工事用金槌として最適に使用できるものであるが、これに限定されることなく、一般的な金槌として広く利用することができる。  The metal hammer of the present invention can be optimally used as a metal hammer for formwork, but is not limited to this and can be widely used as a general metal hammer.
