The present invention relates to a fastening aid used when fastening a member.

ボルト及びナットは、各種の被締結部材を締結するときに用いられる一般的な締結具であるが、一例を挙げれば、例えば、太陽電池パネルを建物の屋根などに設置する際に使用される。具体的には、屋根に固定された取付架台に太陽電池パネルのフレームがボルト及びナットにより締結され、これにより、太陽電池パネルが屋根に取り付けられる。尚、このように、ボルト及びナットを用いて設置される太陽電池パネルとして、従来、例えば、特開２０００−１７９１１７号公報に開示されたものがある。 Bolts and nuts are general fasteners used when fastening various types of members to be fastened. For example, the bolts and nuts are used when a solar cell panel is installed on the roof of a building, for example. Specifically, the frame of the solar cell panel is fastened to the mounting base fixed to the roof with bolts and nuts, and thereby the solar cell panel is attached to the roof. In addition, as a solar cell panel installed using a bolt and a nut in this way, there is one conventionally disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-179117.

特開２０００−１７９１１７号公報JP 2000-179117 A

ところで、ボルト及びナットによって被締結部材を締結する場合、通常、ボルトを回らないように固定してナットを回したり、ナットを回らないように固定してボルトを回す必要がある。したがって、作業者が締結作業を行うときには、一方の手でボルト及びナットの一方を固定し、他方の手でボルト及びナットの他方を回さなければならない。 By the way, when fastening a to-be-fastened member with a bolt and a nut, it is usually necessary to fix the bolt so that it does not rotate and turn the nut, or to fix the nut so as not to rotate and to turn the bolt. Therefore, when the operator performs the fastening operation, one of the bolt and the nut must be fixed with one hand and the other of the bolt and the nut must be turned with the other hand.

しかしながら、上述のようにして締結作業を行ったのでは、両手を使って作業しなければならず、煩わしい。また、ボルト及びナットの一方を固定するためには、工具や手を入れるためのスペースが必要であるが、被締結部材の形状や設置場所によっては、このようなスペースを十分に確保することができず、作業し難い場合もある。 However, if the fastening operation is performed as described above, the operation must be performed using both hands, which is troublesome. Moreover, in order to fix one of the bolts and nuts, a space for inserting a tool or a hand is necessary. However, depending on the shape of the member to be fastened and the installation location, such a space can be sufficiently secured. It may not be possible and it may be difficult to work.

本考案は、以上の実情に鑑みなされたものであって、より簡単にボルト及びナットによって被締結部材を締結することを可能にする締結補助具の提供をその目的とする。 This invention is made | formed in view of the above situation, Comprising: The objective is provision of the fastening aid which makes it possible to fasten a to-be-fastened member with a volt | bolt and a nut more easily.

上記目的を達成するための本考案は、
外周にねじ溝が形成された軸部と、少なくとも１対の平行な二平面を外周に有し、前記軸部の一端に設けられる頭部とを備えたボルトと、前記ボルトの軸部に螺合するナットとによって少なくとも２つの被締結部材の締付部を締め付け、両者を締結する際に用いられる補助具であって、
板状の部材から構成されるとともに、
前記ボルト側に対応した被締結部材の締付部近傍に着脱自在に且つ非回転に係止される基部と、
間隔を隔てて対向するように前記基部から延設され、前記ボルトの頭部の二平面と係合可能となった１対の第１係合片と、
前記１対の第１係合片の間で前記基部から延設され、前記ボルトの頭部の上面と係合可能となった第２係合片とを備えていることを特徴とする締結補助具に係る。 In order to achieve the above object, the present invention
A bolt having a shaft portion having a thread groove formed on the outer periphery, at least one pair of parallel two planes on the outer periphery, and a head provided at one end of the shaft portion; and a screw on the shaft portion of the bolt Auxiliary tool that is used to fasten at least two tightened portions of the fastened members with a nut to be joined and fasten both,
It is composed of a plate-shaped member,
A base portion that is detachably and non-rotatably locked in the vicinity of the tightening portion of the fastened member corresponding to the bolt side;
A pair of first engaging pieces that extend from the base so as to face each other at an interval and are engageable with two planes of the head of the bolt;
A fastening aid, comprising: a second engagement piece extending from the base between the pair of first engagement pieces and capable of engaging with an upper surface of a head portion of the bolt. Related to ingredients.

この考案によれば、被締結部材の締付部に配置されたボルトの頭部を１対の第１係合片及び第２係合片の間に入れて、第１係合片とボルトの頭部の二平面とを係合させ、第２係合片とボルトの頭部の上面とを係合させるとともに、ボルト側に対応した被締結部材の締付部近傍に基部を着脱自在に且つ非回転に係止する。これによって、ボルトの頭部が各係合片により保持され、また、ボルトの頭部の回転が規制される。 According to this device, the head of the bolt disposed at the tightening portion of the member to be fastened is placed between the pair of first engagement pieces and the second engagement pieces, Engaging the two flat surfaces of the head, engaging the second engaging piece and the upper surface of the head of the bolt, and detaching the base in the vicinity of the tightening portion of the fastened member corresponding to the bolt side; Lock non-rotating. Thereby, the head of the bolt is held by each engaging piece, and the rotation of the head of the bolt is restricted.

この後、このようにして締結補助具により保持されたボルトにナットを締め付ければ、被締結部材の締付部を締め付けて、少なくとも２つの被締結部材を締結することができる。その際、当該締結補助具によってボルトの頭部の回転が規制され、ボルトが回転しないようになっているので、締結作業を行う作業者は、一方の手でボルトを固定するといったことを行うことなく、ナットを回して締め付けることができる。このため、作業者は、片手で作業を行うことができるし、また、工具や手を入れるためのスペースが不要であり、ボルト側のスペースが狭くても作業し易い。尚、被締結部材の締結後は、当該締結補助具を被締結部材から取り外しても良い。 Thereafter, when the nut is tightened on the bolt held by the fastening aid in this way, the tightening portion of the fastened member can be fastened to fasten at least two fastened members. At that time, since the rotation of the head of the bolt is regulated by the fastening aid and the bolt is prevented from rotating, the operator who performs the fastening work should fix the bolt with one hand. It can be tightened by turning the nut. For this reason, the operator can work with one hand, does not need a space for putting tools or hands, and is easy to work even if the space on the bolt side is narrow. In addition, you may remove the said fastening aid from the to-be-fastened member after fastening to-be-fastened member.

このように、本考案に係る締結補助具によれば、当該締結補助具によってボルトを非回転に保持することができるので、作業者は、ナットを締める作業だけで済み、より簡単且つ効率的に被締結部材を締結することができる。 Thus, according to the fastening aid according to the present invention, the bolt can be held non-rotating by the fastening aid, so that the operator only needs to tighten the nut, making it easier and more efficient. The fastened member can be fastened.

尚、前記締結補助具は、前記第１係合片の対向方向と平行な直線に沿って折り返されるように前記基部から延設された折り返し片を更に備え、前記基部は、前記折り返し片との間に形成される隙間に前記ボルト側に対応した被締結部材の締付部近傍が挿入されることによりこの被締結部材に装着されるように構成されていても良い。この場合、基部と折り返し片との間に形成される隙間に被締結部材の締付部近傍が挿入されて締結補助具が装着されると、折り返し片と締付部近傍との係合関係によって当該締結補助具及びボルトの頭部の回転が規制される。 The fastening aid further includes a folded piece extending from the base portion so as to be folded along a straight line parallel to the facing direction of the first engaging piece, and the base portion is connected to the folded piece. It may be configured to be attached to the fastened member by inserting the vicinity of the fastened portion of the fastened member corresponding to the bolt side into the gap formed therebetween. In this case, when the vicinity of the fastening portion of the member to be fastened is inserted into the gap formed between the base and the folded piece and the fastening aid is attached, the engagement relationship between the folded piece and the vicinity of the fastening portion The rotation of the fastening aid and the head of the bolt is restricted.

また、前記締結補助具は、前記第１係合片の対向方向と垂直な直線に沿って折り返されるように前記基部から延設された折り返し片を更に備え、前記基部は、前記折り返し片との間に形成される隙間に前記ボルト側に対応した被締結部材の締付部近傍が挿入されることによりこの被締結部材に装着されるとともに、前記被締結部材に装着された状態で、前記被締結部材に対し前記垂直な直線と平行な方向にスライド移動自在に構成されていても良い。この場合には、基部と折り返し片との間に形成される隙間に被締結部材の締付部近傍を挿入して締結補助具を装着した後、当該締結補助具をボルト側に被締結部材に対してスライド移動させることにより、第１係合片とボルトの頭部の二平面とを係合させ、第２係合片とボルトの頭部の上面とを係合させる。そして、このときにも、上記と同様、折り返し片と締付部近傍との係合関係によって当該締結補助具及びボルトの頭部の回転が規制される。 The fastening aid may further include a folded piece extending from the base portion so as to be folded along a straight line perpendicular to the facing direction of the first engagement piece, and the base portion is connected to the folded piece. The vicinity of the tightening portion of the fastened member corresponding to the bolt side is inserted into the gap formed between the fastened member and the fastened member, and the fastened member is attached to the fastened member. It may be configured to be slidable in a direction parallel to the vertical straight line with respect to the fastening member. In this case, after inserting the vicinity of the fastening portion of the fastened member into the gap formed between the base and the folded piece and mounting the fastening aid, the fastening aid is attached to the fastened member on the bolt side. The first engaging piece and the two flat surfaces of the bolt head are engaged with each other by sliding, and the second engaging piece and the upper surface of the bolt head are engaged. And also at this time, similarly to the above, the rotation of the fastening aid and the head of the bolt is restricted by the engagement relationship between the folded piece and the vicinity of the fastening portion.

この場合において、前記第１係合片の一方を、前記第１係合片の他方と対向する側とは反対側の側面が、前記ボルト側に対応した被締結部材に当接するように形成すれば、ナット締付時に生じるボルトの回転力によって１対の第１係合片がその対向方向に互いに離れるように開く力がこれに作用しても、その力を第１係合片の一方に当接した被締結部材で受けることができるので、第１係合片が互いに離れるように開くのを防止することができる。これにより、ナットを所定の締付トルクで確実に締めることができる。 In this case, one of the first engaging pieces is formed such that a side surface opposite to the side facing the other of the first engaging pieces comes into contact with a fastened member corresponding to the bolt side. For example, even if a force that opens the pair of first engaging pieces away from each other in the opposite direction due to the rotational force of the bolt generated when the nut is tightened acts on one of the first engaging pieces, Since it can receive by the to-be-fastened member which contact | abutted, it can prevent that a 1st engagement piece opens away from each other. As a result, the nut can be securely tightened with a predetermined tightening torque.

また、前記第１係合片は、互いに対向する対向面の、前記基部側とは反対側の端部に、対向間隔が広くなるように面取りが形成されていても良い。このようにすれば、ボルトの頭部を第１係合片及び第２係合片の間に入れて、第１係合片とボルトの頭部の二平面とを係合させたり、第２係合片とボルトの頭部の上面とを係合させる際に、その作業の容易化を図ることができる。 Further, the first engaging piece may be chamfered so that a facing interval is widened at an end portion of the facing surfaces facing each other on the side opposite to the base side. If it does in this way, the head of a bolt will be put between the 1st engagement piece and the 2nd engagement piece, and the 2nd plane of the head of a bolt and the 1st engagement piece may be engaged, or the 2nd When engaging the engaging piece with the upper surface of the head of the bolt, the work can be facilitated.

また、前記第２係合片の先端側及び付け根側には、前記ボルトの外周面とそれぞれ係合する係合部が形成されていても良い。このようにすれば、第２係合片の延設方向における締結補助具の移動がボルトの頭部外周と係合部との係合関係によって規制され、当該締結補助具が移動しなくなるので、取り付けた締結補助具が位置ずれしたり、脱落するのを防止することができる。 Moreover, the engaging part which each engages with the outer peripheral surface of the said bolt may be formed in the front end side and base side of the said 2nd engagement piece. In this way, the movement of the fastening aid in the extending direction of the second engagement piece is restricted by the engagement relationship between the head outer periphery of the bolt and the engagement portion, and the fastening aid stops moving. It is possible to prevent the attached fastening aid from being displaced or falling off.

また、前記第２係合片は、その付け根側よりも先端側の方が前記第１係合片との間の高さ方向における間隔が狭くなるように傾斜して形成されていても良い。このようにすれば、第２係合片がボルトの頭部の上面と係合する際に弾性変形して、この弾性変形した第２係合片が元の形状に戻ろうとする力によりボルトの頭部が押さえられるため、上記と同様、取り付けた締結補助具が位置ずれしたり、脱落するのを防止することができる。 Further, the second engagement piece may be formed so as to be inclined so that a distance in a height direction between the second engagement piece and the first engagement piece is narrower than a base side. In this way, the second engaging piece is elastically deformed when engaged with the upper surface of the head of the bolt, and the elastically deformed second engaging piece is restored to its original shape by the force of the bolt. Since the head is pressed, it is possible to prevent the attached fastening aid from being displaced or falling off as described above.

また、前記第２係合片は、その付け根側から先端側にかけての部分が前記第１係合片とは異なる高さに設けられるとともに、前記付け根側が屈曲して前記基部に接続されていても良い。 In addition, the second engagement piece may be provided with a portion from the base side to the tip side at a height different from that of the first engagement piece, and the base side may be bent and connected to the base portion. good.

以上のように、本考案に係る締結補助具によれば、ボルト及びナットを用いた被締結部材の締結作業をより簡単且つ効率的に実施することができる。 As described above, according to the fastening aid according to the present invention, the fastening work of the fastened member using the bolt and the nut can be performed more easily and efficiently.

その際、当該締結補助具１によってボルト５０の頭部５３の回転が規制され、ボルト５０が回転しないようになっているので、締結作業を行う作業者は、一方の手でボルト５０を固定するといったことを行うことなく、ナット５５を回して締め付けることができる。このため、作業者は、片手で作業を行うことができるし、また、工具や手を入れるためのスペースが不要であり、ボルト５０側のスペースが狭くても作業し易い。尚、締結後は、当該締結補助具１を取付金具６０から取り外しても良い。 At that time, since the rotation of the head 53 of the bolt 50 is restricted by the fastening aid 1 and the bolt 50 is prevented from rotating, the operator who performs the fastening operation fixes the bolt 50 with one hand. Without doing this, the nut 55 can be turned and tightened. For this reason, the operator can work with one hand, and does not require a space for putting tools or hands, and is easy to work even if the space on the bolt 50 side is narrow. In addition, you may remove the said fastening aid 1 from the attachment metal fitting 60 after fastening.

このように、本例の締結補助具１によれば、当該締結補助具１によってボルト５０を非回転に保持することができるので、作業者は、ナット５５を締める作業だけで済み、より簡単且つ効率的に取付金具６０及び支持金具７０を締結することができる。 Thus, according to the fastening assisting tool 1 of this example, the bolt 50 can be held non-rotating by the fastening assisting tool 1, so that the operator only needs to tighten the nut 55, and it is easier and easier. The mounting bracket 60 and the support bracket 70 can be fastened efficiently.

また、第１係合片１５の対向面と先端面との交差部に面取り１６を形成しているので、ボルト５０の頭部５３を第１係合片１５及び第２係合片２０の間に入れて、第１係合片１５とボルト５０の頭部５３の二平面とを係合させたり、第２係合片２０とボルト５０の頭部５３の上面とを係合させる際に、その作業の容易化を図ることができる。 Further, since the chamfer 16 is formed at the intersection between the opposing surface of the first engagement piece 15 and the tip surface, the head 53 of the bolt 50 is placed between the first engagement piece 15 and the second engagement piece 20. And engaging the first engaging piece 15 with the two flat surfaces of the head portion 53 of the bolt 50, or engaging the second engaging piece 20 with the upper surface of the head portion 53 of the bolt 50, The work can be facilitated.

また、第２係合片２０の先端側屈曲部２１及び付け根側屈曲部２２とボルト５０の頭部５３の上部外周面の面取り部分とを係合させているので、第２係合片２０の延設方向における締結補助具１の移動がボルト５０の頭部５３と屈曲部２１，２２との係合関係によって規制され、当該締結補助具１が移動しなくなるので、取り付けた締結補助具１が位置ずれしたり、脱落するのを防止することができる。 Further, since the distal end side bent portion 21 and the base side bent portion 22 of the second engagement piece 20 and the chamfered portion of the upper outer peripheral surface of the head portion 53 of the bolt 50 are engaged, Since the movement of the fastening aid 1 in the extending direction is regulated by the engagement relationship between the head 53 of the bolt 50 and the bent portions 21 and 22, the fastening aid 1 does not move.
