Description
【０００１】[0001]
本考案はＳＲＣ造用の形鋼に関する。 The present invention relates to a shaped steel for SRC manufacturing.
【０００２】[0002]
従来、ＳＲＣ造に用いる平鋼にあっては、表面に凹凸を設けた各種の形態（実 開昭６０−８０２２０、実開昭６３−１９８７２５）が提案されている。 また棒鋼にあっても、表面に凹凸を設けた各種の形態（実開昭５８−５７４１ １、実開平３−１０５５１３）が提案されている。 それらの凹凸は、鋼材を包むコンクリ−トへのアンカ−効果を高める働きをす るものであり、凹部については、その分鋼材のボリュ−ムの減少や軽量化が計れ るメリットもある。 表面に凹凸を設けた形態は上記のように平鋼や棒鋼では提供されているが、形 鋼ではこれまで見られない。 Conventionally, in flat steel used for SRC construction, various forms in which unevenness is provided on the surface have been proposed (Sho 60-80220, Sho 63-198725). Further, even for steel bars, various forms in which unevenness is provided on the surface (Actual exploitation Sho 58-57411, Exploratory Act 3-105513) have been proposed. These irregularities serve to enhance the anchoring effect on the concrete wrapping the steel material, and the concave portion also has the merit that the volume of the steel material can be reduced and the weight thereof can be reduced. As mentioned above, the form in which unevenness is provided on the surface is provided for flat steel and bar steel, but it has not been seen so far for shaped steel.
【０００３】[0003]
本考案は上記実情に鑑みてなされたもので、ＳＲＣ造での建築構造部材として の軽量化を計ると共に、鋼材を包むコンクリ−トへのアンカ−効果を効率よく高 める形鋼を提供するものである。 The present invention has been made in view of the above circumstances, and provides a shaped steel that not only reduces the weight as a building structural member in SRC construction but also efficiently enhances the anchoring effect on the concrete wrapping the steel material. It is a thing.

上記課題を解決するために、本考案は、形鋼１の各面の表裏両面に、凹部２を 規則的或いは不規則的に表裏が重ならない部位に穿設したものである。 また、前記形鋼１をＨ形鋼とするものである。 さらに、前記凹部２を所定溝幅を有する劣弧凹部３とするものである。 さらにまた、前記凹部２の深さを板厚の半分以内とするものである。 In order to solve the above-mentioned problems, the present invention is one in which recesses 2 are regularly or irregularly formed on both front and back surfaces of each section of shaped steel 1 at positions where the front and back do not overlap. Further, the shaped steel 1 is an H-shaped steel. Further, the concave portion 2 is a poor arc concave portion 3 having a predetermined groove width. Furthermore, the depth of the recess 2 is within half of the plate thickness.
【０００５】[0005]
【実施例】 以下本考案の実施例を示す図によって説明すると、 図１に示すように、Ｈ形鋼４の表面に接合境界部５を避けて劣弧凹部３を幅方 向に均等割に整列させ表裏が重ならないように交互に等間隔に布設する。 また、図２に示すように、前記劣弧凹部３の深さを板厚の半分より僅か浅くす る。EXAMPLE Referring to the drawings showing an example of the present invention, as shown in FIG. 1, the inferior arc recesses 3 are equally divided in the width direction on the surface of the H-shaped steel 4 while avoiding the joining boundary part 5. Align them and lay them alternately at equal intervals so that the front and back do not overlap. Further, as shown in FIG. 2, the depth of the inferior arc recess 3 is made slightly shallower than half the plate thickness.
【０００６】[0006]
本考案は以上のようで、形鋼１の表面に形成した凹部２によって鋼材を包むコ ンクリ−ト６への強力なアンカ−効果が発生し、形鋼１とコンクリ−ト６とが強 固に一体化する。そのために従来のように形鋼１とコンクリ−ト６とが強度的に 分離されアンカ−効果が殆どない場合と比較して、本考案においては形鋼１の強 度とコンクリ−ト６の強度とがアンカ−効果により相乗的に作用して高耐力構造 を得ることが可能となる。 また、凹部２の欠損体積分の形鋼１の軽量化が実現する。 本考案の形鋼１をＳＲＣ造に使用することによって、容易に軽量強固な建築構 造が可能となった。 The present invention is as described above, and the concave portion 2 formed on the surface of the shaped steel 1 exerts a strong anchoring effect on the concrete 6 enclosing the steel material, and the shaped steel 1 and the concrete 6 are strengthened. Integrated into. Therefore, compared to the case where the shaped steel 1 and the concrete 6 are separated from each other in strength as in the conventional case and there is almost no anchor effect, in the present invention, the strength of the shaped steel 1 and the strength of the concrete 6 are increased. By the anchor effect, and act synergistically, it becomes possible to obtain a high yield strength structure. Further, the weight of the shaped steel 1 corresponding to the missing volume of the recess 2 is realized. By using the shaped steel 1 of the present invention for SRC construction, a lightweight and strong construction structure can be easily achieved.
