Description

本発明は、部材接合方法に関する。  The present invention relates to a member joining method.

周知のように、架構構造物とは、柱部材及びこれに接合された梁部材によって床や屋根等を支持する構造物を指す。これら柱部材及び梁部材は、それぞれ工場で製造された後、架構構造物の建築現場（現地）に運搬されて当該現地にて接合される。現地での一般的な柱部材と梁部材の接合方法は以下の通りである。   As is well known, the frame structure refers to a structure that supports a floor, a roof, and the like by a column member and a beam member joined to the column member. These column members and beam members are each manufactured at a factory, then transported to a construction site (site) of a frame structure and joined at the site. The general method for joining column members and beam members in the field is as follows.

まず、Ｈ鋼である柱部材のフランジ部に、柱側仮止め孔及び柱側位置決め孔を有するラグプレートを予め溶接しておく。一方、同じくＨ鋼である梁部材のウェブ部に、梁側仮止め孔及び梁側位置決め孔を予め形成しておく。上記の柱部材を水平面に対して垂直となるように設置した後、柱側仮止め孔と梁側仮止め孔が対向し、且つ柱側位置決め孔と梁側位置決め孔が対向するように梁部材を配置する。   First, a lug plate having a column side temporary fixing hole and a column side positioning hole is welded in advance to a flange portion of a column member made of H steel. On the other hand, a beam-side temporary fixing hole and a beam-side positioning hole are formed in advance in a web portion of a beam member that is also H steel. After installing the above column member so as to be perpendicular to the horizontal plane, the beam member so that the column side temporary fixing hole and the beam side temporary fixing hole are opposed to each other, and the column side positioning hole and the beam side positioning hole are opposed to each other. Place.

この状態で、柱側位置決め孔及び梁側位置決め孔にシノ（位置決め用治具）を貫通させて位置決めを行った後、柱側仮止め孔及び梁側仮止め孔に仮止めボルトを貫通させてナットで固定することで柱部材と梁部材を仮止めする。仮止め終了後、柱部材と梁部材の本溶接を行うことで接合作業は完了する。なお、ラグを用いた部材同士の接合方法については下記特許文献１を参照されたい。  In this state, after positioning by inserting a shino (positioning jig) into the column side positioning hole and beam side positioning hole, the column side temporary fixing hole and beam side temporary fixing hole are passed through temporary fixing bolts. The column member and the beam member are temporarily fixed by fixing with a nut. After the temporary fixing, the joining work is completed by performing the main welding of the column member and the beam member. In addition, please refer to the following patent document 1 about the joining method of the members using a lug.

特開昭６１−２１８８８７号公報JP-A-61-218887

上記のような接合作業の完了後、シノ、仮止めボルト及びナットは除去されるため、柱部材と梁部材の接合部には２つの貫通孔が残されることになる。これら貫通孔の内面の塗装は不十分になることが多く、そのまま放置すると錆が発生して腐食の原因となることから、これらの貫通孔を塞ぐ必要がある。   After completion of the joining operation as described above, the shino, the temporary fixing bolt and the nut are removed, so that two through holes remain in the joint portion between the column member and the beam member. The inner surfaces of these through-holes are often insufficiently painted, and if left as they are, rust is generated and causes corrosion, so it is necessary to close these through-holes.

従来では、貫通孔の両端に板材を溶接するか、或いは貫通孔に樹脂系のパテ材等の充填材を充填する等の作業を行うことで貫通孔を塞いでいた。しかしながら、前者の方法では、板材の製作と現地での板材溶接作業に手間が掛かるという問題があり、後者の方法では、同様に現地での充填材の充填作業に手間が掛かり、また充填材のコストが掛かるという問題がある。  Conventionally, the through-holes are closed by performing work such as welding plate materials to both ends of the through-holes or filling the through-holes with a filler such as a resin-based putty material. However, in the former method, there is a problem that it takes time to manufacture the plate material and welding the plate material in the field, and in the latter method, it takes time to fill the filler material in the field as well. There is a problem that costs are increased.

本発明は上述した事情に鑑みてなされたものであり、コストを掛けずに現地での防錆作業を容易とする部材接合方法を提供することを目的とする。    The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a member joining method that facilitates on-site rust prevention work without incurring costs.

上記目的を達成するために、本発明では、部材接合方法に係る第１の解決手段として、予め仮止めボルトが溶接された第１の構造部材と、予め仮止め孔が形成された第２の構造部材とを、前記仮止めボルトが前記仮止め孔に貫通し且つ両部材の表面が接するように配置する第１の工程と、前記仮止めボルトのナット締めによる仮止め後、前記第１の構造部材と前記第２の構造部材との本溶接を行う第２の工程と、前記ナットを外した後、前記仮止め孔から突出している前記仮止めボルトの先端部を切断する第３の工程と、前記仮止め孔と前記仮止めボルトとの隙間を埋める第４の工程と、を有することを特徴とする。  In order to achieve the above object, in the present invention, as a first solving means related to the member joining method, a first structural member to which a temporary fixing bolt is welded in advance and a second structural member in which a temporary fixing hole is formed in advance are provided. A first step of arranging the structural member so that the temporary fixing bolt penetrates the temporary fixing hole and the surfaces of both members are in contact with each other; and after the temporary fixing by tightening the nut of the temporary fixing bolt, A second step of performing a main welding between the structural member and the second structural member; and a third step of cutting a tip end portion of the temporary fixing bolt protruding from the temporary fixing hole after removing the nut. And a fourth step of filling a gap between the temporary fixing hole and the temporary fixing bolt.

また、本発明では、部材接合方法に係る第２の解決手段として、予め仮止めボルト及び位置決めピンが溶接された第１の構造部材と、予め仮止め孔及び位置決め孔が形成された第２の構造部材とを、前記仮止めボルトが前記仮止め孔に貫通し、前記位置決めピンが前記位置決め孔に貫通し且つ両部材の表面が接するように配置する第１の工程と、前記仮止めボルトのナット締めによる仮止め後、前記第１の構造部材と前記第２の構造部材との本溶接を行う第２の工程と、前記ナットを外した後、前記仮止め孔から突出している前記仮止めボルトの先端部と前記位置決め孔から突出している前記位置決めピンの先端部を切断する第３の工程と、前記仮止め孔と前記仮止めボルトとの隙間、及び前記位置決め孔と前記位置決めピンとの隙間を埋める第４の工程と、を有することを特徴とする。   Further, in the present invention, as a second solving means related to the member joining method, a first structural member in which a temporary fixing bolt and a positioning pin are welded in advance, and a second structural member in which a temporary fixing hole and a positioning hole are formed in advance. A first step of arranging the structural member such that the temporary fixing bolt penetrates the temporary fixing hole, the positioning pin penetrates the positioning hole, and the surfaces of both members are in contact with each other; A second step of performing a main welding between the first structural member and the second structural member after temporary fixing by tightening a nut; and the temporary fixing protruding from the temporary fixing hole after removing the nut. A third step of cutting the tip of the bolt and the tip of the positioning pin protruding from the positioning hole, a gap between the temporary fixing hole and the temporary fixing bolt, and a gap between the positioning hole and the positioning pin Fill A fourth step, characterized by having a.

また、本発明では、部材接合方法に係る第３の解決手段として、上記第１または第２の解決手段において、前記第４の工程では、充填材を充填することによって、或いは溶接によって前記隙間を埋めることを特徴とする。   In the present invention, as a third solving means related to the member joining method, in the first or second solving means, in the fourth step, the gap is formed by filling with a filler or by welding. It is characterized by filling.

本発明に係る部材接合方法では、仮止めボルトを、仮止め孔を埋めるための孔埋め部材として兼用しているため、孔埋め用の部材を製作する必要がある点では従来と同様であるが、これらの孔埋め部材の溶接作業は工場内での第１の構造部材の製作時に完了するため、現地でのシール溶接作業は不要になると共に、本溶接の完了後は不要な部分を切断するだけで良いので現地での作業が容易となる。
また、従来では充填材を用いて孔全体を埋めていたのに対し、本発明では仮止め孔と仮止めボルトの隙間のみ埋めれば良いため、充填材の使用量も大幅に削減できる。
すなわち、本実施形態に係る部材接合方法によると、コストを掛けずに現地での防錆作業を容易とすることが可能となる。 In the member joining method according to the present invention, since the temporary fixing bolt is also used as a hole filling member for filling the temporary fixing hole, it is the same as the conventional one in that a member for hole filling needs to be manufactured. Since the welding work for these hole-filling members is completed when the first structural member is manufactured in the factory, on-site seal welding work is not necessary, and unnecessary parts are cut after the main welding is completed. It is only necessary to work on site.
Further, in the past, the entire hole was filled using a filler, but in the present invention, only the gap between the temporary fixing hole and the temporary fixing bolt needs to be filled, so that the amount of filler used can be greatly reduced.
That is, according to the member joining method according to the present embodiment, it is possible to facilitate local rust prevention work without incurring costs.

本実施形態における部材接合方法の各工程を表す模式図である。It is a schematic diagram showing each process of the member joining method in this embodiment.

以下、本発明の一実施形態について、図面を参照しながら説明する。
図１（ａ）はＨ鋼である柱部材１０と梁部材２０の接合状態を示す側面図であり、図１（ｂ）は図１（ａ）のＡ−Ａ矢視断面図である。柱部材１０のフランジ部には、予め仮止めボルト１１ａ及びテーパ形状を成す位置決めピン１１ｂがスタッド溶接されたラグプレート１１（第１の構造部材）が予め溶接されている。一方、梁部材２０のウェブ部２１（第２の構造部材）には、仮止め孔２１ａ及び位置決め孔２１ｂが予め形成されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig.1 (a) is a side view which shows the joining state of the column member 10 and beam member 20 which are H steel, FIG.1 (b) is AA arrow sectional drawing of Fig.1 (a). A lug plate 11 (first structural member), in which a temporary fixing bolt 11a and a positioning pin 11b having a tapered shape are stud-welded in advance, is welded to the flange portion of the column member 10 in advance. On the other hand, a temporary fixing hole 21 a and a positioning hole 21 b are formed in advance in the web portion 21 (second structural member) of the beam member 20.

本実施形態における部材接合方法の各工程は以下の通りである。まず、上記の柱部材１０を水平面に対して垂直となるように設置した後、図１（ａ）（ｂ）に示すように、仮止めボルト１１ａが仮止め孔２１ａに貫通し、位置決めピン１１ｂが位置決め孔２１ｂに貫通し且つ両部材１１、２１の表面が接するように梁部材２０を配置する（第１の工程）。位置決めピン１１ｂが位置決め孔２１ｂに貫通することによって、ラグプレート１１と梁部材２０のウェブ部２１、つまり柱部材１０と梁部材２０との位置決めがなされる。なお、位置決めピン１１ｂはテーパ形状を成しているため、位置決め孔２１ｂに対する位置決めピン１１ｂの挿入作業（位置決め作業）が容易となる。   Each process of the member joining method in this embodiment is as follows. First, after the column member 10 is installed so as to be perpendicular to the horizontal plane, as shown in FIGS. 1A and 1B, the temporary fixing bolt 11a penetrates the temporary fixing hole 21a and the positioning pin 11b. The beam member 20 is arranged so as to penetrate the positioning hole 21b and the surfaces of both the members 11 and 21 are in contact with each other (first step). When the positioning pin 11b penetrates the positioning hole 21b, the lug plate 11 and the web portion 21 of the beam member 20, that is, the column member 10 and the beam member 20 are positioned. Since the positioning pin 11b has a tapered shape, it is easy to insert the positioning pin 11b into the positioning hole 21b (positioning operation).

次に、図１（ａ）（ｂ）に示すように、仮止めボルト１１ａをナット３０によって締付け固定することで仮止めを行った後、ラグプレート１１と梁部材２０のウェブ部２１、つまり柱部材１０と梁部材２０との本溶接を行う（第２の工程）。次に、図１（ｃ）に示すように、ナット３０を外した後、仮止め孔２１ａから突出している仮止めボルト１１ａの先端部と、位置決め孔２１ｂから突出している位置決めピン１１ｂの先端部を切断し（第３の工程）、さらに、仮止め孔２１ａと仮止めボルト１１ａとの隙間、及び位置決め孔２１ｂと位置決めピン１１ｂとの隙間に樹脂系のパテ材等の充填材４０を充填することによって、各隙間を埋める（第４の工程）。   Next, as shown in FIGS. 1A and 1B, the temporary fixing bolt 11a is temporarily fixed by tightening and fixing with a nut 30 and then the web portion 21 of the lug plate 11 and the beam member 20, that is, the column. The main welding of the member 10 and the beam member 20 is performed (second step). Next, as shown in FIG. 1 (c), after removing the nut 30, the tip of the temporary fixing bolt 11a protruding from the temporary fixing hole 21a and the tip of the positioning pin 11b protruding from the positioning hole 21b (Third step), and further, the gap between the temporary fixing hole 21a and the temporary fixing bolt 11a and the gap between the positioning hole 21b and the positioning pin 11b are filled with a filler 40 such as a resin-based putty material. Thus, each gap is filled (fourth step).

以上のような本実施形態における部材接合方法では、仮止めボルト１１ａと位置決めピン１１ｂを、仮止め孔２１ａと位置決め孔２１ｂを埋めるための孔埋め部材として兼用しているため、孔埋め用の部材を製作する必要がある点では従来と同様であるが、これらの仮止めボルト１１ａと位置決めピン１１ｂの溶接作業は工場内でのラグプレート１１の製作時に完了するため、現地でのシール溶接作業は不要になると共に、本溶接の完了後は不要な部分を切断するだけで良いので現地での作業が容易となる。
また、仮止め孔２１ａと位置決め孔２１ｂを完全に塞ぐためには充填材４０が必要であるが、従来のように充填材で孔全体を埋めていたのに対し、仮止め孔２１ａと仮止めボルト１１ａとの隙間、及び位置決め孔２１ｂと位置決めピン１１ｂとの隙間にのみ充填材４０を充填すれば良いため、充填材４０の使用量も大幅に削減できる。
すなわち、本実施形態における部材接合方法によると、コストを掛けずに現地での防錆作業を容易とすることが可能となる。 In the member joining method in the present embodiment as described above, the temporary fixing bolt 11a and the positioning pin 11b are also used as a hole filling member for filling the temporary fixing hole 21a and the positioning hole 21b. However, since the welding operation of the temporary fixing bolt 11a and the positioning pin 11b is completed when the lug plate 11 is manufactured in the factory, the on-site seal welding operation is not necessary. In addition to being unnecessary, after the completion of the main welding, it is only necessary to cut the unnecessary portion, so that the work at the site becomes easy.
Further, in order to completely close the temporary fixing hole 21a and the positioning hole 21b, the filler 40 is necessary, but the entire hole is filled with the filler as in the prior art, whereas the temporary fixing hole 21a and the temporary fixing bolt are used. Since the filler 40 only needs to be filled in the gap between the positioning hole 21b and the positioning pin 11b, the amount of the filler 40 used can be greatly reduced.
That is, according to the member joining method in the present embodiment, it is possible to facilitate local rust prevention work without incurring costs.
