Description

本発明は、鋼板とコンクリートの複合構造からなる建造物の壁面や天井面に物体を取付るための金物に係り、特に原子力発電用建造物に好適な物体取付用の金物を備えた鋼板とコンクリートの複合構造体に関するものである。   The present invention relates to a hardware for mounting an object on a wall surface or a ceiling surface of a building having a composite structure of a steel plate and concrete, and more particularly, a steel plate and a concrete provided with an object mounting hardware suitable for a building for nuclear power generation. It is related with the composite structure of.

コンクリート構造体としては、張力部材に鉄筋を用いた、いわゆる鉄筋コンクリートが一般的であるが、近年、張力部材に鋼板を用いたコンクリートの複合構造体、いわゆるＳＣ造構造体が、コンクリートの打設に形板を必要としない利点がかわれて、例えば原子力発電設備などの建造物に用いられるようになっている。   As a concrete structure, a so-called reinforced concrete using a reinforcing bar as a tension member is generally used. However, in recent years, a concrete composite structure using a steel plate as a tension member, a so-called SC structure is used for placing concrete. The advantage of not requiring a shape plate is changed, and it is used for a building such as a nuclear power generation facility.

ところで、このＳＣ造構造体による建造物の場合、その壁面や天井面に、配管や電気器具などの物体を取付ける際には、別途、所定の取付金物(物体を取付けるための部材)をＳＣ造の鋼板に溶接し、この取付金物を用いて物体などを取付けるようにしていた。   By the way, in the case of a building made of this SC structure, when attaching an object such as a pipe or an electric appliance to the wall surface or ceiling surface, a predetermined mounting hardware (member for attaching the object) is separately made of SC. It was welded to the steel plate of this, and the object etc. were attached using this attachment metal fitting.

しかしながら、この場合、取付けるべき物体によっては荷重が足りないことがあり、このときは、インサートスタッドと呼ぶ埋込部材を用い、ＳＣ造の鋼板にインサートスタッドと同じ大きさの孔を開け、そこにインサートスタッドを挿入し、ＳＣ造の鋼板にインサートスタッドを溶接した上で、当該インサートスタッドを埋込んだ形でコンクリートを打設し、このインサートスタッドに取付金物を取付けていた(例えば、特許文献１参照。)。   However, in this case, depending on the object to be attached, the load may be insufficient. In this case, using an embedded member called an insert stud, a hole made in the same size as the insert stud is made in an SC steel plate, and there is After inserting the insert stud and welding the insert stud to the SC steel plate, the concrete was placed in a form in which the insert stud was embedded, and a mounting hardware was attached to the insert stud (for example, Patent Document 1). reference.).

また、この取付金物として工事用吊り金具が用いられる場合があるが、このとき従来技術では、コンクリート打設現場で工事用吊り金具をボルトなどで取付けていた。
特開２００３−１４７８５９号公報 In some cases, a construction hanging bracket is used as the mounting hardware. At this time, in the prior art, the construction suspension bracket is attached with a bolt or the like at the concrete placing site.
JP 2003-147859 A

上記従来技術は、ＳＣ造構造体の鋼板に対する埋込部材の固定に溶接技法が適用されている点に配慮がされておらず、以下の問題があった。   The above prior art does not take into consideration that the welding technique is applied to the fixing of the embedded member to the steel plate of the SC structure, and has the following problems.

(1)
溶接のための準備や溶接員が必要となるので、作業シーケンス上、工程が長くなり、作業時間と工数が増加する。 (1)
Since preparation for welding and a welder are required, a process becomes long on a work sequence, and work time and man-hours increase.

(2)
溶接による歪み、コンクリート打設等の影響により、インサートしたスタッドが鋼板に対して直角にならないケースが発生し、鋼板とスタッドに隙間ができ、埋込部材に必要な許容荷重が満せなくなってしまうというケースの発生が避けられない。 (2)
Due to the effects of welding distortion, concrete placement, etc., the inserted stud may not be perpendicular to the steel plate, creating a gap between the steel plate and the stud, making it impossible to satisfy the allowable load required for the embedded member. The occurrence of the case is inevitable.

(3)
取付金物や工事用吊り金具の取付が現場での作業になるため、足場が必要になって、作業時間と工数が増加し、且つ、足場が組めない現場の場合、施工が不能になってしまう虞がある。 (3)
Installation of mounting hardware and construction suspension brackets is an on-site operation, which requires a scaffold, increases the work time and man-hours, and makes it impossible to construct if the site cannot be assembled. There is a fear.

本発明の目的は、鋼板の表面に取付金物を備えたＳＣ造構造体における上記した問題を克服することにある。   An object of the present invention is to overcome the above-described problems in an SC structure having an attachment metal on the surface of a steel plate.

上記目的は、鋼板の表面に取付金物を備えたＳＣ造構造体において、前記取付金物の固定に使用される埋込金物が、一方の端部に雌ネジ穴を備えた異形鉄筋材の棒状鋼材で作られ、前記鋼板が、前記ネジ留めのためのボルトを通すための貫通孔を備え、前記取付金物が、基板となる鉄板を備え、前記鉄板と前記棒状鋼材が、前記貫通孔を通した前記ボルトにより、前記鋼板を挟んで当該鋼板にネジ留め固定され、前記棒状鋼材が前記ネジ留め固定されただけの状態でＳＣ造構造体のためのコンクリート躯体に埋め込まれているようにして達成される。   In the SC structure having a mounting metal on the surface of a steel plate, the embedded metal used for fixing the mounting metal is a bar-shaped steel bar of a deformed reinforcing bar having a female screw hole at one end. The steel plate is provided with a through hole for passing a bolt for screwing, the mounting hardware is provided with an iron plate as a substrate, and the iron plate and the rod-shaped steel material are passed through the through hole. The bolt is fixed to the steel plate with the bolt sandwiched between the steel plates, and the rod-shaped steel material is embedded in the concrete frame for the SC structure in a state where the steel plate is simply fixed with the screw. The

このとき、前記棒状鋼材の前記雌ネジ穴にゆるみ止め剤が適用されているようにしてもよい。   At this time, a loosening prevention agent may be applied to the female screw hole of the rod-shaped steel material.

本発明によれば、以下の効果が得られる。   According to the present invention, the following effects can be obtained.

(1) ネジ式固定により、溶接作業が不要となる。 (1) No need for welding work due to screw type fixing.

(2) 先行取り付けが可能となるため、現場取付作業が不要となる。 (2) Pre-installation is possible, so no on-site installation work is required.

(3) 先行取り付けが可能となるため、現場での取り付け用足場組立作業が不要となる。 (3) Since it is possible to attach in advance, there is no need to assemble the scaffold for installation on site.

以下、本発明によるＳＣ造構造体用取付金物について、図示の実施形態により詳細に説明する。   Hereinafter, the mounting hardware for SC structure according to the present invention will be described in detail with reference to the illustrated embodiments.

ここで、図１は、本発明の一実施形態を説明するための部分断面図で、図２は、同じく一実施形態において、コンクリートを打設してＳＣ構造の天井スラブ(又は壁)が形成された状態を説明するための部分断面図であり、これらの図において、１は鋼板、２は貫通孔、３は棒状鋼材、４は鉄板、５は雄ネジ部材である。また、１１は座金(ワッシャー)、１２はコンクリート躯体、そして１３は補強部材(補強用のスタッド)である。   Here, FIG. 1 is a partial cross-sectional view for explaining one embodiment of the present invention, and FIG. 2 is a concrete structure in which a ceiling slab (or wall) of SC structure is formed by placing concrete in the same embodiment. FIG. 2 is a partial cross-sectional view for explaining a state where the heat treatment is performed. In these drawings, 1 is a steel plate, 2 is a through hole, 3 is a rod-shaped steel material, 4 is an iron plate, and 5 is a male screw member. Further, 11 is a washer (washer), 12 is a concrete frame, and 13 is a reinforcing member (reinforcing stud).

鋼板１は、コンクリートの施工現場で、図２に示すように、コンクリート躯体１２が打設されることにより、ＳＣ造構造体として完成され、例えば原子力発電設備などの建造物における床部分を構成するものであり、従って、この図１では、鋼板１の下面が天井面になっている。そして、この鋼板１としては、通常、６ｍｍ程度の厚さのものが使用されている。   As shown in FIG. 2, the steel plate 1 is completed as an SC structure by placing a concrete frame 12 as shown in FIG. 2, and constitutes a floor portion in a building such as a nuclear power generation facility, for example. Therefore, in this FIG. 1, the lower surface of the steel plate 1 is a ceiling surface. And as this steel plate 1, the thickness of about 6 mm is normally used.

このとき補強部材１３は、コンクリート躯体１２の中に埋め込まれ、ＳＣ造構造体の強度の一旦を担っているもので、このため、鋼板１の一方の面に所定のパターンにより所要本数が溶接され、これにより予めＳＣ造構造体用の鋼板として作られているものである。   At this time, the reinforcing member 13 is embedded in the concrete housing 12 and is responsible for the strength of the SC structure. For this reason, the required number is welded to one surface of the steel plate 1 by a predetermined pattern. In this way, it is made in advance as a steel plate for an SC structure.

棒状鋼材３は、従来技術におけるインサートスタッドに相当する部材で、例えば長さが２００ｍｍ程度で、直径が３５ｍｍ程度の異形鉄筋材で作られている。そして、その一方の端部(図１では下側の端部)には、当該端部に開口した形で、ボルト５を係合させるための雌ネジ穴が切ってある。   The rod-shaped steel material 3 is a member corresponding to an insert stud in the prior art, and is made of a deformed reinforcing bar material having a length of about 200 mm and a diameter of about 35 mm, for example. One end portion (the lower end portion in FIG. 1) has a female screw hole for engaging the bolt 5 in a shape opened to the end portion.

このとき、鋼板１の所定の位置には、例えばボール盤などの穿孔機械により予め貫通孔２が形成してあり、これにより鋼板１の他方の側(図１では下側)から棒状鋼材３の雌ネジ穴にボルト５がねじ込めるようになっている。また、このとき、貫通孔３の大きさを、ボルト５が通るには充分であるが、棒状鋼材３の直径よりはかなり小さくなるようにしておく。   At this time, a through-hole 2 is formed in advance at a predetermined position of the steel plate 1 by a drilling machine such as a drilling machine, so that the female side of the bar-shaped steel material 3 is formed from the other side (lower side in FIG. 1) of the steel plate 1. The bolt 5 can be screwed into the screw hole. At this time, the size of the through hole 3 is sufficient for the bolt 5 to pass through, but is made to be considerably smaller than the diameter of the rod-shaped steel material 3.

ここで、鉄板４は、配管や電気器具などの物体を取付ける際に使用する取付金物の基板となるもので、通常、方形や円形の鋼板で作られ、これに、例えば配管支持構造物や工事用吊り金具などの部材が取付けられていて、全体として取付金物を構成するためのものである。そして、これにはボルトを通すための孔、いわゆる透孔が少なくとも２個、設けてある。   Here, the iron plate 4 serves as a mounting metal substrate used when mounting an object such as a pipe or an electric appliance, and is usually made of a square or circular steel plate. A member such as a hanging metal fitting is attached to constitute an attachment hardware as a whole. This has at least two holes for passing bolts, so-called through holes.

そこで、図１に示すように、鋼板１を挟んで、一方の側(図では上側)には棒状鋼材３を、その雌ネジ穴が設けてある方の端部が鋼板１に向くようにして配置し、他方の側(図では下側)には鉄板４を配置した上で、鉄板４の透孔にボルト５を通し、鋼板１の貫通孔２を介して、矢印で示すように、棒状鋼材３の雌ネジ穴にねじ込んで行き、座金１１が介在された状態でボルト５を締付け、鋼板１に棒状鋼材３と鉄板４を固定する。   Therefore, as shown in FIG. 1, sandwiching the steel plate 1, the rod-shaped steel material 3 is placed on one side (upper side in the figure), and the end of the side where the female screw hole is provided faces the steel plate 1. After the steel plate 4 is arranged on the other side (lower side in the figure), a bolt 5 is passed through the through hole of the iron plate 4 and the bar-shaped as shown by the arrow through the through hole 2 of the steel plate 1. The steel plate 3 is screwed into the female screw hole, the bolt 5 is tightened with the washer 11 interposed, and the rod-shaped steel member 3 and the iron plate 4 are fixed to the steel plate 1.

このときのボルト５による鉄板４の固定作業は、鋼板１の製造工場や、コンクリート打設現場近傍の現場ヤード・加工場などにおいて、ＳＣ造構造体とするためのコンクリート打設施工に先立って行なう。そして、このとき棒状鋼材３の雌ネジ穴に合成樹脂などのゆるみ止め剤を注入しておき、ボルト５のゆるみ止め防止が得られるようにする。   At this time, the fixing work of the steel plate 4 with the bolt 5 is performed prior to the concrete placing work for making the SC structure at the manufacturing factory of the steel plate 1 or the on-site yard / processing site near the concrete placing site. . At this time, a locking agent such as a synthetic resin is injected into the female screw hole of the rod-shaped steel material 3 so that the locking of the bolt 5 can be prevented.

ここで、鉄板４に複数個の透孔があり、これに対応して鋼板１にも複数個の貫通孔２がある場合は、透孔と貫通孔、それに棒状鋼材３の数だけ、上記のボルト５による固定作業を実施し、鋼板１に鉄板４を取付け、一体化する。   Here, when the steel plate 4 has a plurality of through holes, and the steel plate 1 has a plurality of through holes 2 corresponding thereto, the number of the through holes, the through holes, and the number of the rod-shaped steel members 3 are the same as those described above. The fixing work by the bolt 5 is performed, and the steel plate 4 is attached to the steel plate 1 and integrated.

そして、一体化したものを、現地の揚重機などにより所定の設置場所に搬入し、位置を設定した後、コンクリートを打設してコンクリート躯体１２を形成させてやれば、図２に示すように、棒状鋼材３が埋込部材としてコンクリート躯体１２の中に埋め込まれ、これにより取付金物の基板となる鉄板４が既に鋼板１に取付られているＳＣ造構造体の天井スラブ(又は壁)を完成させることができる。   Then, after the integrated unit is carried into a predetermined installation place by a local lifting machine, the position is set, and then concrete is cast to form the concrete frame 12, as shown in FIG. Then, the steel slab 3 is embedded in the concrete frame 12 as an embedded member, thereby completing the ceiling slab (or wall) of the SC structure in which the iron plate 4 as the mounting metal substrate is already attached to the steel plate 1. Can be made.

このとき、この実施形態によれば、棒状鋼材３がコンクリート躯体１２に埋め込まれ、これにボルト５がねじ込まれて鉄板４が固定されているので、取付金物の基板である鉄板４に必要とする強度を容易に持たせることができる。   At this time, according to this embodiment, the rod-shaped steel material 3 is embedded in the concrete casing 12, and the bolt 5 is screwed into the steel plate 4 so that the iron plate 4 is fixed. Strength can be easily given.

ここで、図３は、鉄板４を２枚用い、２枚の鉄板４の間に配管支持構造物６を設け、全体を取付金物とした場合の一実施形態で、これによりＳＣ造の構造体による天井面に配管８を取り付けることができる。   Here, FIG. 3 shows an embodiment in which two steel plates 4 are used, a pipe support structure 6 is provided between the two steel plates 4, and the whole is an attachment hardware. The pipe 8 can be attached to the ceiling surface.

従って、この実施形態によれば、埋込部材の取付けがボルト５のネジ留めにより得られるので、溶接作業が不要になり、この結果、溶接のための準備や溶接員が不要で、作業シーケンス上での工程が省け、作業時間と工数を抑えることができる。   Therefore, according to this embodiment, since the mounting of the embedded member can be obtained by screwing the bolt 5, welding work is not required. As a result, preparation for welding and a welder are unnecessary, and the work sequence is not necessary. This saves time and man-hours.

また、この実施形態によれば、取付金物の一部である鉄板４がコンクリート打設前、既に鋼板１に取付けられているので、施工現場での取付金物の取付作業が不要になり、この結果、施工現場での足場の組立て作業が省け、この点でも作業時間と工数を抑えることができ、且つ、足場が組めない現場においても施工が可能になる。   In addition, according to this embodiment, since the iron plate 4 which is a part of the mounting hardware is already mounted on the steel plate 1 before placing the concrete, the mounting work of the mounting hardware at the construction site becomes unnecessary. As a result, the assembly work of the scaffold at the construction site can be omitted, and in this respect, the work time and man-hours can be reduced, and the construction can also be performed at the site where the scaffold cannot be assembled.

次に、本発明の他の実施形態について説明すると、図４は、鉄板４に工事用吊り金具７が設けられ、全体として取付金物を形成している場合の一実施形態で、この実施形態でも、鉄板４の取り付け方法は、図１と図２の実施形態と同様の手順で実施することができる。   Next, another embodiment of the present invention will be described. FIG. 4 is an embodiment in which the construction metal fitting 7 is provided on the iron plate 4 and the mounting hardware is formed as a whole. The method of attaching the iron plate 4 can be carried out in the same procedure as in the embodiment of FIGS.

ここで、図５は、ＳＣ造構造体の壁を構成している鋼板１に棒状鋼材３による埋込金物を複数本、所定の間隔で埋設設定し、これに工事用吊り金具７の鉄板を取付け、配管８をワイヤ９により工事用吊り金具７から吊り下げた場合の本発明の一実施形態である。   Here, FIG. 5 shows that the steel plate 1 constituting the wall of the SC structure is set with a plurality of embedded metal bars made of the rod-shaped steel material 3 at predetermined intervals. It is an embodiment of the present invention in the case where the mounting and piping 8 are suspended from the construction hanging bracket 7 by the wire 9.

また、図６は、ＳＣ造構造体の壁を構成している鋼板１に棒状鋼材３による埋込金物を複数本、所定の間隔で埋設設定し、これに工事用吊り金具７の鉄板を取付け、機器１０をワイヤ９により工事用吊り金具７から吊り下げた場合の本発明の一実施形態である。このときの機器１０としては、機械機器、電気機器、電気盤、ラックなどがある。   In addition, FIG. 6 shows that the steel plate 1 constituting the wall of the SC structure is set with a plurality of embedded metal bars made of rod-shaped steel 3 at predetermined intervals, and an iron plate of the construction hanging bracket 7 is attached thereto. This is an embodiment of the present invention when the device 10 is suspended from the construction hanging bracket 7 by the wire 9. As the device 10 at this time, there are a mechanical device, an electric device, an electric panel, a rack, and the like.

更に、図７は、ＳＣ造構造体の天井スラブを構成している鋼板１に棒状鋼材３による埋込金物を複数本、所定の間隔で埋設設定し、これに工事用吊り金具７の鉄板４を複数枚、取付け、配管８をワイヤ９により工事用吊り金具７から吊り下げた場合の本発明の一実施形態である。   Further, FIG. 7 shows that the steel plate 1 constituting the ceiling slab of the SC structure has a plurality of embedded metal bars 3 embedded therein at predetermined intervals. This is an embodiment of the present invention in the case where a plurality of pipes are attached and the pipe 8 is suspended from the construction hanging bracket 7 by the wire 9.

従って、これら図５と図６、それに図７の実施形態によっても、埋込部材の取付けがボルト５のネジ留めにより得られるので、溶接作業が不要になり、この結果、溶接のための準備や溶接員が不要で、作業シーケンス上での工程が省け、作業時間と工数を抑えることができる。   Therefore, also in the embodiment of FIGS. 5 and 6 and FIG. 7, the mounting of the embedded member can be obtained by screwing the bolt 5, so that welding work is not required. No welder is required, processes on the work sequence can be omitted, and work time and man-hours can be reduced.

また、これら図５と図６、それに図７の実施形態によっても、取付金物の一部である鉄板４がコンクリート打設前、既に鋼板１に取付けられているので、施工現場での取付金物の取付作業が不要になり、この結果、施工現場での足場の組立て作業が省け、この点でも作業時間と工数を抑えることができ、且つ、足場が組めない現場においても施工が可能になる。   Also, according to the embodiment of FIGS. 5 and 6 and FIG. 7, the iron plate 4 which is a part of the mounting hardware is already mounted on the steel plate 1 before placing the concrete. As a result, the assembly work of the scaffold at the construction site can be omitted, and as a result, the work time and man-hours can be reduced, and the construction can also be performed at the site where the scaffold cannot be assembled.

本発明は、ＳＣ造の建屋なら、発電設備に限らず適用可能で、例えば原子力発電設備内の工事にも適用することができる。   The present invention can be applied not only to power generation equipment, but also to construction in nuclear power generation equipment, for example, if it is an SC building.
