Description
本発明は、建築鋼材における溶接法に関するものである。 The present invention relates to a welding method for building steel.
建築鋼材には、アングルピースと呼ばれるL形板があり、これは外壁板を取付けるための手段として必要な部材であり、またプレートと呼ばれる平形板があり、これは隣接する角柱材との継ぎ材を連結する手段として必要な部材であり、基本的にはこれらの部材を組み合わせて建築物の骨組みを構築することになる。 In construction steel, there is an L-shaped plate called an angle piece, which is a member necessary as a means for attaching an outer wall plate, and there is a flat plate called a plate, which is a joint material between adjacent prisms. These members are necessary as means for connecting the two. Basically, these members are combined to construct a framework of the building.
従来、建築鋼材である角柱材やH鋼の一面に対してL形板や平形板を溶接する方法としては、L形板でも平形板でも、鋼材との接触面に対して行う溶接は、その形板の一部に片手を当てて固定しかつ防具面を片手で持って行っていたから、前記接触面に対しては点的な仮溶接しかできず、この後で鋼材との接触面に対して本溶接を行うという手数がかかる方法であったし、また最初の仮溶接部にあっては凸凹面を呈するものであった。 Conventionally, as a method of welding an L-shaped plate or a flat plate to one surface of a prismatic steel or H steel, which is a construction steel material, welding to a contact surface with a steel material, whether an L-shaped plate or a flat plate, Since one hand was applied to a part of the shape plate and the armor surface was held with one hand, the contact surface could only be spot-temporarily welded, and then contact the steel contact surface. This is a time-consuming method of performing the main welding, and the first temporary welded portion has an uneven surface.
このような従来の建築鋼材における溶接法を改善する組み立て溶接において、位置ずれや持ち上がりを防止し、溶接外観と作業性の向上を図ることができる部品の溶接法に関して調査したが、間接的なものとして次のような公知文献しか存せず、本発明に係る建築鋼材における溶接法とはほど遠いものであった。 In the assembly welding that improves the welding method in such conventional construction steel materials, we investigated the welding method of parts that can prevent misalignment and lifting, and improve the welding appearance and workability. However, only the following publicly known documents exist, and it is far from the welding method in the construction steel material according to the present invention.
そこで、本発明は、前記した従来の溶接法を改善し、建築鋼材用部材についての新しい組み立て溶接法を提供することを目的とするものである。 Therefore, the present invention aims to improve the above-described conventional welding method and provide a new assembly welding method for members for building steel materials.
本発明は、短手部と長手部から成るL形板の短手部の中央に仮溶接用小孔を設けるとともに長手部の中央に組み立て用小孔を設け、このL形板の短手部の仮溶接用小孔部を鋼材の一面部に置きこの小孔部に仮溶接してL形板を固定し、平形板の中央部には仮溶接用小孔を設けるとともにその左右側部に組み立て用小孔を設け、この平形板の仮溶接用小孔部を鋼材の一面部に置きこの小孔部に仮溶接して平形板を固定し、しかる後に、L形板と鋼材との接触面の左右両側辺部を本溶接し、平形板と鋼材との接触面の左右両側辺部を本溶接してなる建築鋼材における溶接方法である。 The present invention provides a small hole for temporary welding at the center of the short portion of the L-shaped plate composed of a short portion and a long portion, and a small hole for assembly at the center of the long portion, and the short portion of the L-shaped plate. A small hole for temporary welding is placed on one surface of the steel material and temporarily welded to the small hole to fix the L-shaped plate. A small hole for temporary welding is provided in the center of the flat plate and the left and right side portions thereof are provided. A small hole for assembly is provided, the small hole portion for temporary welding of this flat plate is placed on one surface portion of the steel material, and the flat plate is fixed by temporarily welding to this small hole portion, and then the contact between the L-shaped plate and the steel material This is a welding method in building steel materials in which the left and right side portions of the surface are main welded and the left and right side portions of the contact surface between the flat plate and the steel material are main welded.
建築用鋼材に対して組み合わせる部材として使用するアングルピース(L形板)やプレート(平形板)を鋼材面に溶接する際には、溶接作業員は一人で確実に仮溶接用の組み立て溶接をした後に、安定した状態下において本溶接となる面溶接をすることができるようになるのであり、これにより溶接作業員は安全かつ安心して溶接作業を行うことができるのである。 When welding an angle piece (L-shaped plate) or plate (flat plate) used as a member to be combined with steel for building construction to a steel surface, the welding worker surely performed assembly welding for temporary welding alone. Later, it becomes possible to perform surface welding, which is the main welding in a stable state, so that the welding worker can perform the welding operation safely and safely.
本発明は、建築鋼材における溶接方法において、まずL形板の短手部に設けた小孔に溶接を施して鋼材の所定位置に仮溶接の固定をし、また平形板の中央部に設けた小孔に溶接を施して鋼材の所定位置に仮溶接の固定をする。 The present invention is a welding method for building steel, in which first, a small hole provided in the short part of the L-shaped plate is welded to fix the temporary welding at a predetermined position of the steel material, and is provided in the center of the flat plate. A small hole is welded to fix the temporary welding at a predetermined position of the steel material.
しかる後に、L形板の短手部の両側辺部に本溶接をし、また平形板の両側辺部に本溶接をすることになるのである。 After that, the main welding is performed on both sides of the short portion of the L-shaped plate, and the main welding is performed on both sides of the flat plate.
1は建築鋼材の一種の角柱材で、断面四角面を形成する鋼材である。建築鋼材としては他にH鋼材がある。
2は短手部3と長手部4から成るL形板で、このL形板の短手部3の中央には仮溶接用の小孔5を設け、長手部4の中央には組み立てに必要な組み立て用小孔6,6を間隔をおいて設ける。前記仮溶接用の小孔5は2個でもよい。
そこで、溶接作業員は、角柱材1の所定の一面部上にL形板2の短手部3を置き、この短手部の小孔5に仮止めとしての溶接をしてL形板2を角柱材1の所定位置に固定する。
Therefore, the welding worker places the short portion 3 of the L-
しかる後に、L形板の短手部の左右両側辺部に本溶接8,8を行う。 Thereafter, the main weldings 8 and 8 are performed on the left and right sides of the short part of the L-shaped plate.
9は長尺の平形板で、この平形板の中央には仮溶接用の2個の小孔10,10を設け、その他の部分には組み立てに必要な組み立て用小孔11,11,11,11を設ける。前記仮溶接用の小孔10は1個でもよい。
9 is a long flat plate, and two
