【考案の詳細な説明】
本考案はラチス筋で上下に結合された上弦材と下弦材と
の側面部間に、横架材の端部を連結するための側面プレ
ートを設けてなるラチス梁に関する。[Detailed description of the invention] The present invention relates to a lattice beam in which a side plate for connecting the end of a horizontal member is provided between the side parts of an upper chord member and a lower chord member that are vertically connected by a lattice bar. .
従来、このようなラチス梁に側面プレートを設ける場合
に、側面プレートの上端部を型鋼よりなる上弦材の内側
に、また、側面プレートの下端部を型鋼よりなる下弦材
の内側にそれぞれ接合して？着していた。Conventionally, when installing side plates on such a lattice beam, the upper end of the side plate was joined to the inside of the upper chord made of shaped steel, and the lower end of the side plate was joined to the inside of the lower chord made of shaped steel. ? I was wearing it.
それ故、側面プレートの熔接作業を上弦材と下弦材の内
側より行わなければならないために、作業性が悪いこと
と、側面プレートの正確な位置決めが難かしいために、
品質斉一な或品が得難いという欠点があった。Therefore, the work of welding the side plates must be done from the inside of the upper and lower chord members, resulting in poor workability and difficulty in accurately positioning the side plates.
The drawback was that it was difficult to obtain certain products with uniform quality.
本考案の目的とするところは、このような従来の欠点を
克服し、側面プレートの熔接作業を上弦材と下弦材の外

をずらせて設けてもよい。In the illustrated embodiment of the present invention, both side edges 2, 2 of the upper chord member 1 made of shaped steel and both side edges 7 of the lower chord member 6 made of shaped steel are shown.
. 4
The outer surface of the upper end portion 5 is the outer surface of both side edges 2, 2 of the upper chord member 1, and the outer surface of the lower end portion 9 of the side plate 4 is the outer surface of the both side edges 7, 7 of the lower chord member 6. , and the side edges of the upper end portion 5 and lower end portion 9 are welded 1 to the side edges 2 and 7 of the upper chord member 1 and the lower chord member 6, respectively.
0, a pair of side plates 4, 4 are provided in parallel between the side surfaces of the upper chord member 1 and lower chord member 6 of the lattice beam, but these side plates 4, 4 do not necessarily need to be provided in parallel. Alternatively, the mounting positions may be shifted from each other in the length direction of the lattice beam.

いため、作業能率は大巾に向上する。In this way, the present invention draws plate fitting recesses on both side edges of the upper chord made of shaped steel and on both sides of the lower chord made of shaped steel so that they face each other vertically, and The upper and lower ends of the side plate are placed in the matching recess, the outer surface of the upper end of the side plate is connected to the outer surface of both edges of the upper chord, and the outer surface of the lower end of the side plate is connected to both sides of the lower chord. Fit into the outer surface of the edge so that each becomes a smooth surface,
Since the side edges of these upper and lower ends are welded to both side edges of the upper and lower chords, the side plates can be welded from the outside of the upper and lower chords, unlike conventional Compared to the case where the welding work of the side plate is performed from the inside of the upper and lower chord members, the welding work is performed in a more comfortable position, and the work efficiency is greatly improved.

品を容易に得ることができる。In addition, in the present invention, the upper and lower ends of the side plate are fitted into vertically opposing plate fitting recesses formed on both side edges of the upper chord member and both side edges of the lower chord member. Since welding is performed, it is possible to accurately position the side plate without tilting or shifting the position, so it is possible to easily obtain a product with uniform quality.
