Description

この発明は、鉄骨建物における構造部材どうしの長手方向の端部を突き合せた状態で接合する接合構造において、ハイテンボルトを用いないで接合するための接合構造に関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure for joining structural members of a steel frame building with their longitudinal ends facing each other without using high-tensile bolts.

従来、鉄骨建物における梁部材等の構造部材どうしの接合は、梁部材（Ｈ型鋼等）のウェブ面とフランジ面に接合プレートを当接させ、接合プレートと梁部材をハイテンボルトにより締め付け接合していた。 Conventionally, structural members such as beam members in steel-framed buildings are joined together by placing a joining plate in contact with the web surface and flange surface of the beam member (H-beam steel, etc.), and then tightening and joining the joining plate and the beam member with high-tensile bolts. rice field.

しかしながら、現在、ハイテンボルトが極度の品薄状態のため発注してからハイテンボルトが納品されるまで最低８か月が必要である。
（１）そのため建築業者に、お客様から建物の竣工時期の目途が立たないため事業計画が立てられないといった苦情が寄せられている。
特に、競争の早い製造業者等では工場・倉庫等の完成が遅れることにより合理化が達成できず、競合他社との価格競争力において多くの問題が発生している。
（２）すでに建築を請け負った業者の場合は、請負契約をしてから長期にわたり建物の着工ができないため、資材等の価格の値上がりにより、当初契約した請負金額では建物を完成できない、といった問題が発生している。However, due to the extreme shortage of high-tensile bolts at present, it takes at least eight months from the time an order is placed until the high-tensile bolts are delivered.
(1) As a result, customers complained to builders that they could not make business plans because they could not predict when the building would be completed.
In particular, manufacturers with fast competition cannot achieve rationalization due to delays in the completion of factories and warehouses, etc., and many problems are occurring in price competitiveness with competitors.
(2) In the case of a contractor who has already contracted for construction, there is a problem that the building cannot be completed with the contract amount initially contracted due to the price increase of materials, etc., because it is not possible to start construction for a long time after signing the contract. It has occurred.

さらに、ハイテンボルトで構造部材どうしを接合する場合には、ナットの接触面に油分が付着しないように注意すると共に、鉄骨部材の接合部の表面を摩擦面処理する必要があった。 Furthermore, when joining structural members with high-tensile bolts, it was necessary to take care to prevent oil from adhering to the contact surfaces of the nuts, and to apply friction surface treatment to the joint surfaces of the steel frame members.

この発明は、従来の接合構造における上記の問題を解決すべくなされたもので、その目的とするところは、鉄骨建築用の構造部材どうしを隅肉溶接により接合することにより、ハイテンボルト等を用いることなく構造部材の接合が容易にできる新たな接合構造を提供することを課題とする。 The present invention has been made to solve the above-mentioned problems in conventional joint structures, and its object is to join structural members for steel frame construction by fillet welding, using high-tensile bolts and the like. It is an object of the present invention to provide a new joint structure that facilitates jointing of structural members without any joints.

さらに、接合プレートを当接させる構造部材のウェブ面とフランジ面を、構造部材と同様に塗装することができる接合構造を提供することを課題とする。 A further object of the present invention is to provide a joint structure in which the web surface and flange surface of the structural member against which the joint plate abuts can be coated in the same manner as the structural member.
