It is proposed to have a structure that concentrically surrounds the space c.
【０００３】 従来のこの種の耐火被覆構造に於ては、耐火被覆部ｂを構成している耐火被覆 材ｂ1 はそれぞれ、鉄骨丸柱ａに溶接手段の適用で固着された軽鉄下地ｄとして のリップ溝型鋼に対しタッピンねじｅの適用のもとに取付け固定されているが、 軽鉄下地ｄの溶接には専門職が必要となり、人材確保が困難であるばかりでなく 、溶接作業時に発生する火花の養生が必要となり面倒であった。In the conventional fireproof coating structure of this type, the fireproof coating material b 1 forming the fireproof coating portion b is a light iron substrate d fixed to the steel frame round column a by applying welding means. It is attached and fixed to the lip groove type steel under the application of the tapping screw e, but it requires a professional to weld the light iron substrate d, which not only makes it difficult to secure human resources, but also occurs during welding work. It was troublesome because it needed to cure the sparks.
【０００４】 本考案は、このような従来の問題点を一掃することを目的としてなされたもの である。The present invention has been made for the purpose of eliminating such conventional problems.

Plate-shaped metal pieces 3, 3'are attached and fixed to the upper end and the lower end by applying tapping screws 4.
【００１０】 板状金物３，３′は鋼板好ましくは亜鉛メッキ鋼板製であり、半円筒状耐火被 覆材２の裏面に沿う曲率に湾曲されている。下側板状金物３′は上下巾が比較的 小さく、右半分３ａ′に於て右側の耐火被覆材２の裏面に添接固定され、左半分 ３ｂ′は外側方へ突出している。上側板状金物３は下側のものより上下巾が２倍 程度大きく、下半部の右半分３ａに於て右側の耐火被覆材２の裏面に添接固定さ れ、それ以外の部分は外側方へ突出している。The plate-shaped metal parts 3, 3 ′ are made of a steel plate, preferably a galvanized steel plate, and are curved to have a curvature along the back surface of the semi-cylindrical refractory covering material 2. The lower plate-shaped metal piece 3'has a relatively small vertical width, is fixedly attached to the back surface of the right refractory coating material 2 in the right half 3a ', and the left half 3b' projects outward. The upper plate-shaped metal piece 3 has a vertical width about twice as large as that of the lower piece, and is fixed by splicing to the back surface of the right refractory coating material 2 in the right half 3a of the lower half part, and the other parts are outside. It projects toward.
【００１１】 一方鉄骨丸柱５の表面には、上下の板状金物３，３′に充当する位置に、予め 間隔保持ブロック６が接着剤の適用のもとに接着固定されている。間隔保持ブロ ック６として図には上下，左右に振り分けて４ケ所に設けた場合が示されている が、上下にのみ振り分けて２ケ所に設けても或は全体が一つ物であってもよい。On the other hand, on the surface of the steel-framed round pillar 5, a gap holding block 6 is preliminarily adhered and fixed at a position corresponding to the upper and lower plate-shaped metal pieces 3, 3 ′ by applying an adhesive. In the figure, the space holding block 6 is shown to be installed in four places by allocating it to the top, bottom, left and right, but it may be provided only in the top and bottom, and it may be installed in two places, or the whole block is one. Good.
【００１２】 図２に示す状態で、左右の半円筒状耐火被覆材２，２を円筒を形成するように 継ぎ合せると、左側の半円筒状耐火被覆材２の裏面には、上，下板状金物３，３ ′のうち、下端側では左半分３ｂ′，上端側では下半部の左半分３ｂがそれぞれ 添接する。而してこの状態で左耐火被覆材２の表面側から螺入されるタッピンね じ４を用いて上，下板状金具３，３′を左耐火被覆材２に取付け固定することに より、図３に示すように下段耐火被覆部１Ａを一体に組立てることができる。間 隔保持ブロック６は、タッピンねじ４の螺入操作時には、板状金物３，３′への タッピンねじ４の螺入がスムーズに行われるよう、該板状金物３，３′を図４に 示すように後方側から支えると共に、組立て後に於ては、下段耐火被覆部１Ａと 鉄骨丸柱５との間に間隙７を形成する。In the state shown in FIG. 2, when the left and right semi-cylindrical fireproof coating materials 2 and 2 are joined together to form a cylinder, the upper and lower plates are attached to the back surface of the left semicylindrical fireproof coating material 2. Among the metal parts 3, 3 ′, the left half 3 b ′ is attached at the lower end side, and the lower left half 3 b is attached at the upper end side. Then, in this state, the upper and lower plate-shaped metal fittings 3 and 3'are attached and fixed to the left fire-resistant coating material 2 by using the tapping screw 4 screwed from the surface side of the left fire-resistant coating material 2. As shown in FIG. 3, the lower fireproof coating 1A can be integrally assembled. The space holding block 6 is configured such that when the tapping screw 4 is screwed in, the tapping screw 4 can be smoothly screwed into the plate-shaped metal objects 3, 3'as shown in FIG. As shown, it is supported from the rear side, and after assembly, a gap 7 is formed between the lower stage fireproof coating portion 1A and the steel frame round pillar 5.
【００１３】 以下同様にして、中段耐火被覆部１Ｂ次いで上段耐火被覆部１Ｃを組立てるこ とにより、鉄骨丸柱５の全長、即ち床面８から天井面９を少し超える高さの範囲 まで耐火被覆を施すことができる。この場合、図２に示す上側板状金物３は、下 段と中段の耐火被覆部１Ａ、１Ｂを結合一体化する金物として利用される。同様 にして、中段と上段の耐火被覆部１Ｂ、１Ｃを結合一体化してもよい。In the same manner, by assembling the middle-stage fire-resistant coating portion 1B and then the upper-stage fire-resistant coating portion 1C, the fire-resistant coating is applied to the entire length of the steel-framed round pillar 5, that is, the range from the floor surface 8 to a height slightly above the ceiling surface 9. Can be given. In this case, the upper plate-shaped metal piece 3 shown in FIG. 2 is used as a metal piece for integrally combining the lower and middle fire-resistant coating portions 1A and 1B. Similarly, the middle-stage and upper-stage fireproof coating portions 1B and 1C may be combined and integrated.
【００１４】 耐火被覆部１の上端に於ては、図１及び図５に示すように、周隙７の上端を閉 じるように蓋部材１０を取付けると共に、蓋部材１０より上方の鉄骨丸柱５の裸 部５ａに岩綿等の吹付け層１１を形成することができる。At the upper end of the fireproof coating part 1, as shown in FIGS. 1 and 5, the lid member 10 is mounted so as to close the upper end of the circumferential gap 7, and the steel-framed pillar above the lid member 10 is attached. It is possible to form a spray layer 11 of rock wool or the like on the bare portion 5a of 5.
【００１５】 本考案に於て、耐火被覆材２としては、耐火製材料例えばけい酸カルシウムか らなる成形板を用い得る。間隙保持ブロック６及び蓋部材１０は、耐火被覆材２ と同材質のものでよい。In the present invention, the fireproof coating material 2 may be a molded plate made of a fireproof material, for example, calcium silicate. The gap holding block 6 and the lid member 10 may be made of the same material as the fireproof coating material 2.
【００１６】[0016]
本考案耐火被覆構造によれば、耐火被覆部を溶接作業を必要とすることなしに 、従って経験や熟練性を必要とすることなしに構築することが可能になると共に 、溶接火花の養生などの煩雑な作業を省くことができる。 According to the fireproof coating structure of the present invention, it becomes possible to construct the fireproof coating portion without requiring welding work, and thus without requiring experience and skill, and at the same time, for curing welding sparks. Complicated work can be omitted.
