Description
本考案は、芯棒打ち込みアンカーボルト用ハンドホルダーに関し、特に芯棒に打ち棒を当ててアンカーボルトを設置する際に正確、安全に芯棒打ち込みアンカーボルトを設置出来る芯棒打ち込みアンカーボルト用ハンドホルダーに関するものである。 The present invention relates to a core holder driven anchor bolt hand holder, and more particularly to a core holder driven anchor bolt hand holder that can accurately and safely install an anchor bolt when placing the anchor bolt on the core bar. It is about.
従来の芯棒打ち込みアンカーボルト用ハンドホルダーは芯棒打ち込みアンカーボルトのワッシャーやボルト部分に先端部をあてがい、反対にバネなどの手段で出ている打ち棒部をハンマーで打ちつけて設置している。 In the conventional hand holder for core rod driving anchor bolts, the tip portion is attached to the washer or bolt portion of the core rod driving anchor bolt, and on the contrary, the hitting rod portion protruding by means such as a spring is hit with a hammer.
なお一方で握りグリップが付いた芯棒打ち込みアンカーボルト用ハンドホルダーが有るが、特に芯棒打ち込みアンカーボルトのワッシャーや調整ナットにあてがう部分においては一定のストレートの円筒形のみで構成されているものがほとんどである。 On the other hand, there is a hand holder for a core rod driven anchor bolt with a grip grip, but in particular, the portion applied to the washer and adjustment nut of the core rod driven anchor bolt is composed only of a certain straight cylindrical shape. Is almost.
先述の従来の芯棒打ち込みアンカーボルト用ハンドホルダーを使用する場合、芯棒打ち込みアンカーボルトにあてがう部分から打ち棒の入る部分までが一定のストレートの円筒形のため、数をこなして作業する場合、ハンマーで打ち棒の頭を安定して叩き続けて施工することが困難となり、作業者自身がハンマーで違う部分を打ってしまい、例えば芯棒打ち込みアンカーボルトの芯棒が曲がることが有ったり、作業者自身の手を間違って打って怪我をするという欠点が有った。 When using the above-mentioned conventional core rod driving anchor bolt hand holder, when working with a large number of parts because the part from the portion applied to the core rod driving anchor bolt to the portion where the driving rod enters is a straight cylinder, It becomes difficult to work by hitting the head of the hitting rod stably with a hammer, and the worker himself hits a different part with a hammer, for example, the core rod of the anchor rod driving anchor bolt may be bent, There was a drawback of injury by hitting the operator's hand by mistake.
上記課題を解決するために本考案は、複数の円筒形状から成る芯棒打ち込みアンカーボルト用ハンドホルダー(1)であって、下端面部(4)に有るC面形状(3)の下円筒部(2)の下部内径(5)は芯棒打ち込みアンカーボルト(10)の調整ナット(12)に被せた際にガタツキの無い一定の大きさで調整ナット(12)を保持し、又下端面部(4)は、そのC面形状(3)でワッシャー(11)を押さえるように形成され、更に調整ナット(12)、ワッシャー(11)及び雄ねじ(13)全体を充分に覆うことの出来る高さを有するよう該下円筒部(2)は構成されており、一方の上端面部(6)においては、芯棒打ち込みアンカーボルト(10)の芯棒(14)の頭に打ち棒(20)を当ててハンマーにて打ち込むための一定の上部内径(5A)を有する打ち棒(20)のためのガイド用円筒部(2A)が設けられており、これら下円筒部(2)とガイド用円筒部(2A)とが10mmから20mmの範囲内の長さのテーパー形状の円筒部(2B)で一体形成されていることを特徴とする。 In order to solve the above-mentioned problems, the present invention provides a core holder driven anchor bolt hand holder (1) having a plurality of cylindrical shapes, wherein the lower cylindrical portion (3) has a C-plane shape (3) on the lower end surface portion (4). The lower inner diameter (5) of 2) holds the adjusting nut (12) with a certain size without any play when it is put on the adjusting nut (12) of the anchor rod driven anchor bolt (10). ) Is formed so as to hold the washer (11) with its C-surface shape (3), and has a height that can sufficiently cover the entire adjustment nut (12), washer (11) and male screw (13). The lower cylindrical portion (2) is configured such that, in one upper end surface portion (6), the hammer (20) is applied to the head of the core rod (14) of the core rod driving anchor bolt (10). Constant for driving in A guide cylindrical portion (2A) for a striking rod (20) having an inner diameter (5A) is provided, and the lower cylindrical portion (2) and the guide cylindrical portion (2A) are in the range of 10 mm to 20 mm. It is characterized by being integrally formed by a tapered cylindrical portion (2B) having an inner length.
本考案の芯棒打ち込みアンカーボルト用ハンドホルダーは以上のような構成であるから、ハンドホルダーとして簡単な構造で有りながら、下部内径で調整ナットをしっかりと保持し、更には下端面部に有るC面形状がワッシャーを押さえつけてくれるため、安定して芯棒をガイド用円筒部に挿入して打ち棒にて施工出来るものとなる。
又作業する場所が他の施工物などが有る狭い場所であっても上に高く打ち棒を出して芯棒を叩いて設置出来る優れたものとなる。Since the core holder driven anchor bolt hand holder of the present invention is configured as described above, it has a simple structure as a hand holder, while holding the adjustment nut firmly at the lower inner diameter, and also the C surface on the lower end surface Since the shape presses the washer, the core rod can be stably inserted into the guide cylindrical portion and can be constructed with the hitting rod.
Moreover, even if the place where the work is performed is a narrow place where there is other construction work, it is excellent that it can be installed by hitting the core bar with a high hitting stick.
特にワッシャー部分を抑える下端面部のC面形状の有る下円筒部が上円筒部に比べて大きな円筒形として形成されているので、コンクリートに下穴を開けて、先に芯棒打ち込みアンカーボルトを挿入しておいても安定して本案の芯棒打ち込みアンカーボルト用ハンドホルダーをコンクリート面上に置くことが出来る。この安定して置く事が出来ることで、数が多い設置現場での作業効率が上がるという非常に重要な副次的効果となる。 In particular, the lower cylindrical part with the C-surface shape of the lower end surface part that suppresses the washer part is formed as a larger cylindrical shape than the upper cylindrical part, so drill a pilot hole in the concrete and insert the core bolt into the anchor bolt first However, the core holder driven anchor bolt hand holder can be placed on the concrete surface stably. This stable placement is a very important secondary effect of increasing the work efficiency at a large number of installation sites.
本考案における芯棒打ち込みアンカーボルト用ハンドホルダーの大きさ、形状、円筒部の厚み、デザイン、材質、製造方法等は特に限定されないが施工物である芯棒打ち込みアンカーボルトのボルトの規格に合わせてその下部内径や下円筒部の大きさを決めれば良く、例えばM8であればそれに準じて大きさ、製品厚みを旋盤などの手段で作製すれば良い。
以下、実施側と図面に基づき説明する。The size, shape, cylindrical portion thickness, design, material, manufacturing method, etc. of the core rod driving anchor bolt hand holder in the present invention are not particularly limited, but according to the standard of the core rod driving anchor bolt that is the construction work. What is necessary is just to determine the magnitude | size of the lower internal diameter and a lower cylindrical part, for example, if it is M8, what is necessary is just to produce a magnitude | size and product thickness according to it by means, such as a lathe.
