Description

本考案はコンクリート構造物に固定固着させるアンカーボルトに関する。  The present invention relates to an anchor bolt fixedly fixed to a concrete structure.

従来のコンクリート構造物に設けられたアンカーボルトを埋め込む穴の形状は円筒形の直管であり、使用されるボルトは複雑な構造のものから、単純なボルトを接着剤に頼る間接的固定固着の工法まで多数の特許公開が行われている。しかし、ボルトを埋め込む穴とボルトの形状とが不適合のため確実な効果が上げられない欠点があった。特にクサビを利用した拡開式ボルトではクサビを利用しながら、ボルトを埋め込む穴の形状が円筒形の直管であるためクサビが作用する圧着力だけで構造的抵抗がないため強い力が加わるとボルトはスリップし抜け落ちてしまう問題がある。また単純なボルトを接着剤に頼り、間接的に固定固着させる場合いも同様であり接着剤を使用する場合いには材料の変質、接着効果の消失、対応年数の不明など経年劣化によるボルトの抜け落ちる危険性の高い欠点がある。  The shape of the hole for embedding anchor bolts provided in conventional concrete structures is a cylindrical straight pipe, and the bolts used are of complicated structure, so simple bolts can be indirectly fixed and fixed using adhesives. Many patents have been published up to the construction method. However, there is a drawback that the positive effect cannot be achieved because the hole for embedding the bolt and the shape of the bolt are incompatible. In particular, in the case of an expansible bolt that uses wedges, when using a wedge, the shape of the hole in which the bolt is embedded is a cylindrical straight pipe. There is a problem that the bolt slips and falls off. The same applies to the case where a simple bolt is relied on an adhesive and fixed indirectly and fixed. When an adhesive is used, the bolt falls off due to deterioration over time, such as deterioration of the material, loss of the adhesive effect, and unknown years of support. There are high risk disadvantages.

考案が解決しようとする課題Problems that the device tries to solve

アンカーボルトでクサビを利用する場合い、クサビが作用する圧着力だけではボルトを埋め込む穴が円筒形の直管であるため穴壁にはボルトに対して抵抗する術はなく、そのため長期の振動により歪みと緩みが生じ強い力が加わるとボルトはスリップし抜け落ちてしまう問題がある。したがってボルトを埋め込む穴はボルトと抵抗し合いスリップを防ぐ形状に変更する必要があり、ボルトも又、穴壁の形状に適合させ、スリップを防ぐ抜止力のある形状に変更することが課題である。  When using wedge with an anchor bolt, there is no way to resist the bolt on the hole wall because the hole for embedding the bolt is a cylindrical straight tube with only the crimping force that the wedge acts on. There is a problem that the bolt slips and falls when a strong force is applied due to distortion and loosening. Therefore, it is necessary to change the hole in which the bolt is embedded into a shape that resists the bolt and prevents slipping, and the bolt is also adapted to the shape of the hole wall and changed to a shape having a retaining force to prevent slipping. .

課題を解決するための手段Means for solving the problem

コンクリート構造物に設けられた逆円錐形の穴1に固定固着させる、アンカーボルトであって、そのアンカーボルトは中空7を有するパイプ状のものであり、その一端にはオスネジ8が外周部に設けられていて対する側には単数又は複数の切込み6が設けられたボルトとクサビ9とからなるアンカーボルトであり、クサビ9は中間に円筒部10と先端部にはドーム形突起11とが設けられ後端は円錐形状部9とからなることが特長のアンカーボルトである。上記の切り込み6にクサビ9を差し上記の穴1に押し込むと、クサビ9の作用によりボルト5は扇形又はロート状に押し開かれ、穴1の頂点3にボルト5本体が直接固定固着され、クサビ9に設けられた円筒部10とドーム形突起11との効果により抜止力が更に強化されることも特長のアンカーボルト。  An anchor bolt fixedly fixed to an inverted conical hole 1 provided in a concrete structure, and the anchor bolt is a pipe-shaped member having a hollow 7, and a male screw 8 is provided at an outer peripheral portion at one end thereof. It is an anchor bolt composed of a bolt 9 and a wedge 9 provided with one or a plurality of cuts 6 on the opposite side, and the wedge 9 is provided with a cylindrical portion 10 in the middle and a dome-shaped projection 11 at the tip. The anchor bolt is characterized in that the rear end includes a conical portion 9. When the wedge 9 is inserted into the notch 6 and pushed into the hole 1, the bolt 5 is pushed into a fan shape or a funnel shape by the action of the wedge 9, and the bolt 5 body is directly fixed and fixed to the apex 3 of the hole 1.

以下図面と符号を基に本考案の実施形態を具体的に説明する。
図1において、アンカーボルト5を埋め込む穴1は開口部2から奥へ拡がる逆円錐形の穴1を確保する。そのためには使用するボルトのサイズに合せた紙管4を作り、作られた紙管4は設計図に記されたボルトの位置、図2の状態でセットした後でコンクリートを打つ。固まった後紙管4を取り除き逆円錐形の穴1を確保する。ここで穴1を確保するための形状物質は紙管だけではなく、発泡スチロールその他コンクリートの圧力に堪えられるものであれば選択は自由であり本考案では紙管4を使用する。
Embodiments of the present invention will be specifically described below with reference to the drawings and reference numerals.
In FIG. 1, a hole 1 for embedding an anchor bolt 5 secures an inverted conical hole 1 extending from the opening 2 to the back. For this purpose, a paper tube 4 is made in accordance with the size of the bolt to be used, and the paper tube 4 thus produced is set in the position of the bolt indicated in the design drawing, in the state shown in FIG. After hardening, the paper tube 4 is removed to secure the inverted conical hole 1. Here, the shape material for securing the hole 1 is not limited to the paper tube, but can be selected as long as it can withstand the pressure of foamed polystyrene or other concrete, and the paper tube 4 is used in the present invention.

上記の穴1に伴アンカーボルト5を埋め込む穴1の形状とボルト5の形状を適合させるため円錐形のクサビ9を使用するものであって、そのボルトは凝固剤が注入できる中空7を有するパイプ状のものであり、その一端にはオスネジ8が外周部に設けられており、対する側には単数又は複数の切り込み6が設けられたボルトとクサビ9とからなるアンカーボルトであり、クサビ9の中間に円筒部10と先端がドーム形突起11とが設けられていて後端は円錐形状部9とからなることが特長のアンカーボルトである。A conical wedge 9 is used to match the shape of the hole 1 and the shape of the bolt 5 in which the anchor bolt 5 is embedded in the hole 1, and the bolt has a hollow 7 into which a coagulant can be injected. It is an anchor bolt composed of a bolt and a wedge 9 provided with a male screw 8 at one end thereof on the outer peripheral portion and a single or plural cuts 6 on the opposite side. An anchor bolt is characterized in that a cylindrical portion 10 and a dome-shaped protrusion 11 are provided at the front end and a conical portion 9 at the rear end.

上記の切り込み6にクサビ9を差したボルト5を上記の穴1に押し込むとクサビ9の作用により扇形又はロート状に押し開かれたボルト5は穴1の中で互いに抵抗し合い構造的にボルト5本体が直接固定固着する。
この時クサビ9に設けられた円筒部10とドーム形突起11の効果により抜止力が更に強化されることも特長のアンカーボルトであり、ボルト5が固定固着した後ボルト5の後孔部7から隙間を埋める凝固剤を注入し隙間が埋まったところで開口部2と後孔部7に流出防止のパッキン具12と13を詰め、その後基本部材であるつり金具14と座金15の順にセットし、最後にメスネジのナット16で締める、その後つり金具14に設置部材が取り付けられるアンカーボルトである。
When the bolt 5 in which the wedge 9 is inserted into the notch 6 is pushed into the hole 1, the bolt 5 pushed into a fan shape or funnel shape by the action of the wedge 9 resists each other in the hole 1 and structurally bolts. 5 The main body is directly fixed and fixed.
At this time, the anchor bolt is also characterized in that the retaining force is further strengthened by the effect of the cylindrical portion 10 provided on the wedge 9 and the dome-shaped protrusion 11, and from the rear hole portion 7 of the bolt 5 after the bolt 5 is fixed and fixed. A coagulant filling the gap is injected, and when the gap is filled, the opening 2 and the rear hole 7 are filled with the outflow prevention packing tools 12 and 13, and then set in the order of the suspension member 14 and the washer 15 as the basic members. The anchor bolt is fastened with a nut 16 of a female screw, and then the installation member is attached to the suspension bracket 14.

したがって逆円錐形の穴1の中でクサビ9の作用により扇形又はロート状に押し開かれたボルト5が互いに抵抗し合う構造で直接固定固着するためコンクリートが破砕しない限り、構造上抜け落ちることのないアンカーボルトあり、従来のアンカーボルトのような接着剤に頼り間接的に固定固着させる施工を不要とするアンカーボルトである。Accordingly, the bolts 5 pushed and opened in a fan shape or funnel shape by the action of the wedge 9 in the inverted conical hole 1 are directly fixed and fixed in a structure that resists each other, so that the concrete will not fall out unless the concrete is crushed. There is an anchor bolt, and it is an anchor bolt that does not require construction to be fixed and fixed indirectly by relying on an adhesive like a conventional anchor bolt.

ここで使用する凝固剤は隙間を埋めるための礎材であってアンカーボルト5を固定固着し荷重を支えようとするものではない。しかし凝固剤はボルト5及びクサビ9の鉄鋼部材を被覆して、空気及び水分を遮断するため錆と腐蝕を防ぎ経年劣化を防止する効果がある。したがって露出している外部ボルト5とナット16に注意点検するだけでメンテナンスが簡単なアンカーバルトである。The coagulant used here is a foundation material for filling the gap, and is not intended to support the load by fixing and fixing the anchor bolt 5. However, the coagulant coats the steel members of the bolt 5 and the wedge 9 and blocks air and moisture, thereby preventing rust and corrosion and preventing aging. Therefore, the anchor bolt is easy to maintain simply by carefully checking the exposed external bolt 5 and nut 16.

紙管4を使用する理由は事前に穴1の確保が先行できることで後付施工による穴1の確保には危険が伴ない時間もかかり粉塵による被害も問題である。紙管を使用することで穴1の確保は容易になり上記の被害も回避され、紙管4の使用範囲は拡く、したがって使用する企業も多くなるアンカーボルトである。The reason for using the paper tube 4 is that the hole 1 can be secured in advance, and the securing of the hole 1 by the post-installation process takes time without danger, and damage caused by dust is also a problem. By using a paper tube, the hole 1 can be easily secured and the above-mentioned damage can be avoided, and the use range of the paper tube 4 is expanded.

コンクリート構造物であるトンネル工事において天井板又は吸排ダクトを設置するため設けられた逆円錐形の穴1に固定固着させるためのアンカーボルトであってそのアンカーボルト5は中空7を有するパイプ状のものであり、その一端には、オスネジ8が外周部に設けられていて、対する側には単数又は複数の切り込み6が設けられたボルトとクサビ9とからなるアンカーボルト5であって、そのクサビ9の中間に円筒部10と先端がドーム形突起11とが設けられ後端は円錐形状部9とからなることが特長のアンカーボルトである。An anchor bolt for fixing and fixing to an inverted conical hole 1 provided for installing a ceiling plate or a suction duct in tunnel construction which is a concrete structure, and the anchor bolt 5 is a pipe having a hollow 7 The anchor bolt 5 is composed of a bolt 9 and a wedge 9 provided with a male screw 8 at one end thereof and provided with one or a plurality of cuts 6 on the opposite side. The anchor bolt is characterized in that a cylindrical portion 10 and a dome-shaped protrusion 11 are provided at the front end and a conical portion 9 is formed at the rear end.

上記の切り込み6にクサビ9を差したボルト5を上記の穴1に押し込むと扇形又はロート状に押し開かれたボルト5本体が穴1の頂点3に直接固定固着する。この時クサビ9に設けられた円筒部10とドーム形突起11との効果により抜止力が更に強化されることも特長のアンカーボルトであり、構造上抜け落ちることのないアンカーボルトである。When the bolt 5 having the wedge 9 inserted into the notch 6 is pushed into the hole 1, the bolt 5 body pushed open in a fan shape or funnel shape is fixed and fixed directly to the apex 3 of the hole 1. At this time, the anchor bolt is characterized in that the retaining force is further strengthened by the effect of the cylindrical portion 10 provided on the wedge 9 and the dome-shaped protrusion 11, and the anchor bolt does not fall out structurally.

アンカーボルト5が固定固着後、ボルト5の後孔部7から隙間を埋める凝固剤を注入し埋まった後、開口部2と後孔部7に流出防止のパッキン具12と13を詰め、その後基本部材のつり金具14と座金15の順にセットし最後にメスネジのナット16で締める。その後つり金具14に設置部材の天井板又は吸排ダクトを取り付けられるアンカーボルトであり、ここで使用する凝固剤もアンカーボルト5を固定固着し荷重を支える材料ではなく、穴1の隙間を埋めると共に鉄鋼部材のボルト5とクサビ9を被覆し空気と水分を遮断し、錆と腐蝕を防ぎ外部のボルト5とナット16の点検だけで済むメンテナンスが簡単なアンカーボルトである。After the anchor bolt 5 is fixed and fixed, a coagulant filling the gap from the rear hole portion 7 of the bolt 5 is injected and buried, and then the opening 2 and the rear hole portion 7 are filled with the outflow prevention packing tools 12 and 13, and then the basic The member's bracket 14 and washer 15 are set in this order, and finally tightened with a female screw nut 16. It is an anchor bolt to which the ceiling plate or suction / exhaust duct of the installation member can be subsequently attached to the hanging bracket 14, and the coagulant used here is not a material that fixes and fixes the anchor bolt 5 to support the load, but fills the gap in the hole 1 and steel. The bolt 5 and wedge 9 of the member are covered to block air and moisture, prevent rust and corrosion, and can be easily maintained by simply inspecting the external bolt 5 and nut 16.

コンクリート構造物においては天井板又は吸排ダクトだけできなく横の壁板・標識・掲示板・照明器具など場合いと場所により、アンカーボルト5は上下、左右、斜めと要求される方向性は様々である。しかし施工、プロセスは実施例1と同様であり、いずれの工事においても設計図に記されたアンカーボルト5の位置に穴1が正確に確保されていれば設置部材は簡単に設置することが可能なアンカーボルトである。  In a concrete structure, not only a ceiling plate or a suction / exhaust duct but also a horizontal wall plate, a sign, a bulletin board, a lighting fixture, and the like and the direction in which the anchor bolt 5 is required to be up and down, left and right, and diagonal are various. However, the construction and process are the same as in Example 1. In any construction, if the hole 1 is accurately secured at the position of the anchor bolt 5 indicated on the design drawing, the installation member can be easily installed. An anchor bolt.
