The pair of the surface steel plates 12 and 13 are connected only by a tie bar fixed to the surface steel plates 12 and 13 at both ends, and the attaching plate 23 is attached at least to a range in which the plurality of the tie bars 15 are attached.

Description

本発明は、例えば、ダクト、配管、ケーブルトレイ、電線管などの長尺物を支持するサポート取り付け構造に関する。   The present invention relates to a support mounting structure that supports a long object such as a duct, piping, a cable tray, and a conduit.

従来、建物などに配設されるダクト、配管、ケーブルトレイ、電線管などの長尺物を支持するサポートの定着部の補強方法として、定着部に対して鋼材からなる補強部材を適宜箇所に溶接補強したり、補強部材をボルト孔により固定しているのが一般的である（例えば、特許文献１参照）。
特許文献１では、少なくとも互いに対向配置された一対の金属板の一方の内側に電気配線用のダクトを取り付けると共に、その開口部を金属板の表面側に設けた金属板ユニットを予め形成し、その金属板ユニットの内側にコンクリートを打設している。
この際、一対の金属板の間はタイバーによって連結されている。また、一対の金属板の内面側には補強用のスタッドが突出して設けられ、このスタッドがコンクリートに埋め込まれることにより、金属板とコンクリートとの剥離が防止されている。 Conventionally, as a method of reinforcing a fixing part of a support that supports long objects such as ducts, pipes, cable trays, and electric pipes installed in a building or the like, a reinforcing member made of steel is welded to the fixing part at an appropriate place. It is common to reinforce or fix the reinforcing member with a bolt hole (for example, see Patent Document 1).
In Patent Document 1, a duct for electric wiring is attached to one inner side of at least one pair of metal plates arranged opposite to each other, and a metal plate unit having an opening provided on the surface side of the metal plate is formed in advance. Concrete is placed inside the metal plate unit.
At this time, the pair of metal plates are connected by a tie bar. Further, a reinforcing stud protrudes on the inner surface side of the pair of metal plates, and the studs are embedded in the concrete, thereby preventing the metal plate and the concrete from peeling off.

しかしながら、従来のサポートの定着部の補強技術においては、以下のような問題があった。
すなわち、サポートを金属板のどの場所に取り付けるかによって、スタッド１本当たりの荷重分担が異なるため、スタッドの耐荷重によってはサポートの取り付け位置が制限されるという問題があった。
また、スタッドはサポートの取り付け位置の反対側に配置され、コンクリートで覆われて見えない状態であるため、スタッドの位置を把握することができない。従って、設計図でスタッドの位置を確認しながらサポートを取り付ける必要があり、サポートの取り付け作業を行う際に施工に時間を要するという問題があった。 However, the conventional technology for reinforcing the fixing portion of the support has the following problems.
That is, since the load sharing per stud differs depending on where the support is attached to the metal plate, there is a problem that the attachment position of the support is limited depending on the load resistance of the stud.
Moreover, since the stud is disposed on the opposite side of the mounting position of the support and is covered with concrete and cannot be seen, the position of the stud cannot be grasped. Therefore, it is necessary to attach the support while confirming the position of the stud on the design drawing, and there is a problem that it takes time to perform the installation when the support is attached.

本発明は、上述する問題点に鑑みてなされたもので、簡素かつ軽量な構造で剛性を高めることができる上、サポート部材の取り付け位置を強度確認した上で取り付けることができるサポート取り付け構造を提供することを目的とする。   The present invention has been made in view of the above-described problems, and provides a support mounting structure that can increase rigidity with a simple and lightweight structure and can be mounted after confirming the strength of the mounting position of the support member. The purpose is to do.

上記目的を達成するため、本発明に係るサポート取り付け構造では、所定間隔を存して互いに対向する一対の表面鋼板同士の間にコンクリートを打設した鋼板コンクリート構造体の表面に、取付板を介してサポート部材を取り付けるサポート取り付け構造において、前記一対の表面鋼板は、両端が各表面鋼板に固定されるタイバーのみによって接続され、前記取付板は、少なくとも複数の前記タイバーが取り付けられている範囲に取り付けられていることを特徴とする。   In order to achieve the above object, in the support mounting structure according to the present invention, the surface of a steel plate concrete structure in which concrete is placed between a pair of surface steel plates facing each other at a predetermined interval is interposed via a mounting plate. In the support attachment structure for attaching the support member, the pair of surface steel plates are connected only by tie bars whose ends are fixed to the surface steel plates, and the attachment plate is attached in a range where at least a plurality of the tie bars are attached. It is characterized by being.

本発明では、サポート部材の取付板をタイバーの存在を確認した上で取り付けることができることから、取付板からの荷重が複数のタイバーに略均等に分散させることが容易に可能となる。   In the present invention, since the attachment plate of the support member can be attached after confirming the presence of the tie bar, the load from the attachment plate can be easily distributed substantially evenly to the plurality of tie bars.

また、本発明に係るサポート取り付け構造は、前記表面鋼板の内面には、該内面に沿って延在するリブが固定されていることを特徴とする。
本発明では、タイバーやスタッドのようなピンポイントの補強と異なり、複数のリブによって少なくとも線状の補強が可能となることから、取付板を設けた場合の荷重の分散を効率良く行うことができる。 The support mounting structure according to the present invention is characterized in that a rib extending along the inner surface is fixed to the inner surface of the surface steel plate.
In the present invention, unlike pin-point reinforcement such as tie bars and studs, at least linear reinforcement is possible with a plurality of ribs, so that load distribution can be efficiently performed when a mounting plate is provided. .

また、本発明に係るサポート取り付け構造は、前記リブの先端に前記表面鋼板と平行な内側鋼板が固定されていることを特徴とする。
本発明では、より一層の強度を確保することができる。尚、この場合においては、コンクリートを打設する際の生コン流入を妨げず、満遍なく表面鋼板間に打設できるようにリブ並びに内側鋼板の位置を考慮するのが好ましい。 Moreover, the support attachment structure which concerns on this invention is characterized by the inner side steel plate parallel to the said surface steel plate being fixed to the front-end | tip of the said rib.
In the present invention, further strength can be ensured. In this case, it is preferable to consider the positions of the ribs and the inner steel plates so that they can be uniformly placed between the surface steel plates without impeding the flow of raw concrete when placing concrete.

また、本発明に係るサポート取り付け構造は、前記リブが、複数の平板部材を格子状に配列してなるものであることを特徴とする請求項２に記載のサポート取り付け構造。
本発明では、平板部材を格子状に配列してリブを構成することにより、リブの強度を一層向上させることができる。また、リブが生コンの流入の妨げになり難い。 In the support mounting structure according to the present invention, the rib is formed by arranging a plurality of flat plate members in a lattice shape.
In the present invention, the strength of the ribs can be further improved by arranging the flat plate members in a lattice pattern to form the ribs. In addition, the ribs are unlikely to hinder the inflow of raw kon.

また、本発明に係るサポート取り付け構造は、前記リブが、断面略Ｌ字型を有する複数のアングル材を格子状に配列してなるものであることを特徴とする。
本発明では、断面略Ｌ字型の一片を表面鋼板に当接させて固定することができるので、簡単且つ強固にリブを表面鋼板に固定することができる。 The support mounting structure according to the present invention is characterized in that the rib is formed by arranging a plurality of angle members having a substantially L-shaped cross section in a lattice shape.
In the present invention, a piece having a substantially L-shaped cross section can be fixed in contact with the surface steel plate, so that the rib can be fixed to the surface steel plate easily and firmly.

また、本発明に係るサポート取り付け構造は、前記リブが、断面略Ｃ字型を有する複数のチャンネル材を格子状に配列してなるものであることを特徴とする。
本発明では、チャンネル材の一片を表面鋼板に当接させて固定することができるので、簡単且つ強固にリブを表面鋼板に固定することができる。 In the support mounting structure according to the present invention, the rib is formed by arranging a plurality of channel members having a substantially C-shaped cross section in a lattice shape.
In the present invention, since one piece of the channel material can be fixed in contact with the surface steel plate, the rib can be fixed to the surface steel plate easily and firmly.

本発明のサポート取り付け構造によれば、簡素かつ軽量な構造で剛性を高めることができる上、サポート部材の取り付け位置を強度確認した上で取り付けることができる。   According to the support attachment structure of the present invention, the rigidity can be increased with a simple and lightweight structure, and the attachment position of the support member can be attached after confirming the strength.

FIG.

以下、本発明の実施の形態によるサポート取り付け構造について、図面に基づいて説明する。   Hereinafter, a support mounting structure according to an embodiment of the present invention will be described with reference to the drawings.

（第１の実施の形態）
図１に示すように、本第１の実施の形態によるサポート取り付け構造１０Ａは、ダクト２１（長尺物）を支持するサポート部材２２の取付板２３を鋼板コンクリート構造体１１に取り付けたものである。 (First embodiment)
As shown in FIG. 1, the support attachment structure 10 </ b> A according to the first embodiment is obtained by attaching an attachment plate 23 of a support member 22 that supports a duct 21 (long object) to a steel plate concrete structure 11. .

鋼板コンクリート構造体１１は、所定間隔を存して互いに対向する一対の表面鋼板１２，１３の間にコンクリート１４を打設している。また、一対の表面鋼板１２，１３は、両端が各表面鋼板１２，１３の内面に溶接にて固定されるタイバー１５のみによって接続されている。   In the steel plate concrete structure 11, concrete 14 is placed between a pair of surface steel plates 12 and 13 facing each other at a predetermined interval. Moreover, a pair of surface steel plates 12 and 13 are connected only by tie bars 15 whose both ends are fixed to the inner surfaces of the respective surface steel plates 12 and 13 by welding.

タイバー１５は、表面鋼板１２，１３を連結してコンクリート１４から受ける圧力によらずその間隔を一定に保持するためのものであり、表面鋼板１２，１３の縦横に均等間隔で配置されている。本実施形態では、図１に示すように、縦方向１０行×横方向１０列で合計１００本のタイバー１５が、表面鋼板１２，１３に略直交して延びるようにそれぞれ配置されている。また、タイバー１５は、同一直径で同一強度のものが用いられており、表面鋼板１２，１３とタイバー１５との接続には、スタッド溶接等が用いられている。
例えば、一方の表面鋼板１２の上に頭付きタイバー１５をスタッド溶接により溶植した後、予め栓溶接のための孔１３ａが穿設されている他方の表面鋼板１３を頭付きタイバー１５の上に載置し、アークスタッド溶接で溶接材料としてのスタッドの先端部分を溶融して孔１３ａを埋める（栓溶接）ことにより、タイバー１５の頭部と表面鋼板１３とを固定する。尚、これらのタイバー１５の接続工法は特に限定されるものではなく、少なくともサポート部材２２を取り付ける側の表面鋼板１３の表面にタイバー１５の頭部が見えていれば（突出はしない）良い。 The tie bars 15 are for connecting the surface steel plates 12 and 13 to keep the distance constant irrespective of the pressure received from the concrete 14, and are arranged at equal intervals in the vertical and horizontal directions of the surface steel plates 12 and 13. In the present embodiment, as shown in FIG. 1, a total of 100 tie bars 15 in a vertical direction of 10 rows and a horizontal direction of 10 columns are arranged so as to extend substantially orthogonal to the surface steel plates 12 and 13. In addition, the tie bar 15 having the same diameter and the same strength is used, and stud welding or the like is used to connect the surface steel plates 12 and 13 and the tie bar 15.
For example, after the headed tie bar 15 is welded on one surface steel plate 12 by stud welding, the other surface steel plate 13 in which a hole 13a for plug welding is previously drilled is placed on the headed tie bar 15. The head portion of the tie bar 15 and the surface steel plate 13 are fixed by placing and melting the tip portion of the stud as a welding material by arc stud welding to fill the hole 13a (plug welding). Note that the connection method of these tie bars 15 is not particularly limited as long as at least the head of the tie bar 15 is visible on the surface of the surface steel plate 13 to which the support member 22 is attached (does not protrude).

このような鋼板コンクリート構造体１１を施工するには、図１に示すように、一対の表面鋼板１２，１３を対向させ、それらの内面に、各タイバー１５の両端をそれぞれ溶接固定する。このようなプレキャスト化されたものを多数製造して施工現場に搬入し、縦横に接続する。
そして、表面鋼板１２，１３の間の空間にコンクリート１４を打設し、そのコンクリート１４が硬化することによって鋼板コンクリート構造体１１が完成する。尚、鋼板コンクリート構造体１１は、主に建物の外壁や仕切壁、床スラブ（基礎スラブ）等として施工されるが、一般に建物における種々の機器類等の長尺物を含めた後付部材（以下、ダクト２１を例に説明する）が、サポート部材２２に支持された状態で設置される。 In order to construct such a steel plate concrete structure 11, as shown in FIG. 1, a pair of surface steel plates 12 and 13 are opposed to each other, and both ends of each tie bar 15 are welded and fixed to the inner surfaces thereof. A large number of such precast products are manufactured, carried to the construction site, and connected vertically and horizontally.
And concrete 14 is cast in the space between surface steel plates 12 and 13, and steel plate concrete structure 11 is completed when concrete 14 hardens. In addition, although the steel plate concrete structure 11 is mainly constructed as an outer wall of a building, a partition wall, a floor slab (foundation slab), etc., generally a retrofitting member including long objects such as various devices in a building ( Hereinafter, the duct 21 will be described as an example), but is installed in a state of being supported by the support member 22.

取付板２３は、表面鋼板１２，１３の表面であって、その裏側に少なくとも複数のタイバー１５が取り付けられている範囲に取り付けられている。ここで、タイバー１５はその先端が表面鋼板１３の表面に露出しており、均一間隔で縦横に配置されていることと相俟って、取付板２３を複数のタイバー１５に跨らせる際に荷重負荷を考慮した位置で溶接固定することができる。   The attachment plate 23 is attached to the surface of the surface steel plates 12 and 13 in a range where at least a plurality of tie bars 15 are attached to the back side thereof. Here, when the tip of the tie bar 15 is exposed on the surface of the surface steel plate 13 and is arranged vertically and horizontally at a uniform interval, the mounting plate 23 is straddled across the plurality of tie bars 15. It can be welded and fixed at a position considering the load.

ダクト２１は、プラント設備の制御室の排気を目的として配設され、サポート部材２２によって支持された状態で表面鋼板１３の表面に沿って延設されている。ダクト２１は、断面形状が円形状の丸ダクトであり、比較的、薄肉の鋼板からなる円柱状のものが用いられているが、例えば、角ダクト等、長尺物の種類は限定されるものではない。   The duct 21 is disposed for the purpose of exhausting the control room of the plant facility, and extends along the surface of the surface steel plate 13 while being supported by the support member 22. The duct 21 is a circular duct having a circular cross-sectional shape, and a cylindrical column made of a relatively thin steel plate is used. For example, the type of a long object such as a square duct is limited. is not.

サポート部材２２は、Ｈ型鋼からなり、取付板２３を介して鋼板コンクリート構造体１１に固定されている。具体的には、ダクト２１を支持する横材２４と、この横材２４を支持する補強材２５とからなる。なお、サポート部材２２は、Ｈ型鋼のほかに、Ｌ型鋼やチャンネル材であっても良い。   The support member 22 is made of H-shaped steel, and is fixed to the steel plate concrete structure 11 via a mounting plate 23. Specifically, the cross member 24 includes a cross member 24 that supports the duct 21 and a reinforcing member 25 that supports the cross member 24. The support member 22 may be L-shaped steel or channel material in addition to H-shaped steel.

取付板２３は、平面視で四角形状の鋼板であって、各辺を溶接によって表面鋼板１３の表面に固定されている。この取付板２３は、少なくとも複数のタイバー１５が取り付けられている範囲に、すなわち表面鋼板１３の裏側に複数のタイバー１５が設けられている領域に取り付けられている。本実施形態では、図１に示すように、表面鋼板１３の表面であってその裏側に縦方向２列×横方向２行で合計４本のタイバー１５が位置する領域に、取付板２３を固定している。そして、上下２つのＨ型鋼２４，２５を、縦方向２行のタイバー１５とそれぞれ同じ高さ位置になるように、且つ、横方向２列のタイバー１５の略中央部にそれぞれ位置するようにして配置している。尚、取付板２３の表面鋼板１３への固定位置や、Ｈ型鋼２４，２５の取付板２３への固定位置は、本実施形態に限定されず適宜設計変更が可能である。   The mounting plate 23 is a rectangular steel plate in plan view, and each side is fixed to the surface of the surface steel plate 13 by welding. The attachment plate 23 is attached in a range where at least the plurality of tie bars 15 are attached, that is, in a region where the plurality of tie bars 15 are provided on the back side of the surface steel plate 13. In the present embodiment, as shown in FIG. 1, the mounting plate 23 is fixed to the surface of the surface steel plate 13 in a region where a total of four tie bars 15 are located in the back side by 2 columns × 2 rows. is doing. The two upper and lower H-shaped steels 24 and 25 are positioned so as to be at the same height as the tie bars 15 in two rows in the vertical direction, and at substantially the center of the two rows of tie bars 15 in the horizontal direction. It is arranged. Note that the fixing position of the mounting plate 23 to the surface steel plate 13 and the fixing position of the H-shaped steels 24 and 25 to the mounting plate 23 are not limited to the present embodiment, and can be appropriately changed in design.

このように、一対の鋼板１２，１３がタイバー１５のみによって接続されるので、取付板２３やＨ型鋼２４，２５やダクト２１の荷重が、表面鋼板１３だけで支持されることなく、各タイバー１５を介して表面鋼板１２及びコンクリート１４によっても支持される。これにより、表面鋼板１２，１３に設けたスタッド（不図示）にてダクト２１等の荷重を負担する場合と比較すると、鋼板コンクリート構造体１１を構成する各部で損傷等が生じ難く、鋼板コンクリート構造体１１の全体としての強度を向上させることができる。従って、サポート部材２２の表面鋼板１３への取り付け位置が制限されず、任意の場所に取り付けることができる。   In this way, since the pair of steel plates 12 and 13 are connected only by the tie bars 15, the loads on the mounting plate 23, the H-shaped steels 24 and 25 and the duct 21 are not supported only by the surface steel plates 13, and each tie bar 15 It is also supported by the surface steel plate 12 and the concrete 14 via Thereby, compared with the case where the load of the duct 21 or the like is borne by the studs (not shown) provided on the surface steel plates 12 and 13, it is difficult to cause damage or the like in each part constituting the steel plate concrete structure 11, and the steel plate concrete structure. The strength of the body 11 as a whole can be improved. Therefore, the attachment position of the support member 22 to the surface steel plate 13 is not limited, and the support member 22 can be attached to an arbitrary place.

このように、本発明のサポート取り付け構造１０Ａにあっては、表面に頭部が露出しているタイバー１５を基準として取付板２３を溶接固定することができるので、ダクト２１からの負荷を略均等にタイバー１５に分散することが可能となる。
また、タイバー１５の頭部が露出しているため、取付板２３を表面鋼板１３に取り付ける作業を行う際に、タイバー１５の位置を確認しながら作業を行うことができ、短時間での施工が可能である。 Thus, in the support mounting structure 10A of the present invention, the mounting plate 23 can be welded and fixed on the basis of the tie bar 15 whose head is exposed on the surface, so that the load from the duct 21 is substantially equal. It is possible to disperse the tie bars 15.
Moreover, since the head of the tie bar 15 is exposed, when performing the work of attaching the mounting plate 23 to the surface steel plate 13, the work can be performed while checking the position of the tie bar 15, and the work can be performed in a short time. Is possible.

（第２の実施の形態）
図２に示すように、第２の実施の形態によるサポート取り付け構造１０Ｂは、第１の実施形態によるサポート取り付け構造１０Ａと比較すると、リブ１６及び内側鋼板１７を備える点で異なっている。尚、それ以外の構成は、第１の実施の形態と同じであるため、同じ符号を用い、ここでは説明を省略する。 (Second Embodiment)
As shown in FIG. 2, the support mounting structure 10 </ b> B according to the second embodiment is different from the support mounting structure 10 </ b> A according to the first embodiment in that it includes a rib 16 and an inner steel plate 17. Since the other configuration is the same as that of the first embodiment, the same reference numerals are used and description thereof is omitted here.

リブ１６は、細長い矩形形状を有する複数の平板部材が格子状に組まれたものであって、表面鋼板１２，１３の内面全体に延在するようにしてそれぞれ固定されている。また、リブ１６の先端すなわち表面鋼板１２，１３と逆側の端部に固定して、表面鋼板１２，１３と略平行に配置された内側鋼板１７が設けられている。   The ribs 16 are formed by a plurality of flat plate members having an elongated rectangular shape assembled in a lattice shape, and are fixed so as to extend over the entire inner surfaces of the surface steel plates 12 and 13. Further, an inner steel plate 17 is provided which is fixed to the tip of the rib 16, that is, the end opposite to the surface steel plates 12 and 13, and is arranged substantially parallel to the surface steel plates 12 and 13.

本第２の実施の形態のサポート取り付け構造１０Ｂによれば、表面鋼板１２，１３の内面にリブ１６と内側鋼板１７を固定したことにより、表面鋼板１２、１３の剛性を高めることができる。これにより、第１の実施の形態と比較して、鋼板コンクリート構造体１１の全体としての強度を一層向上させることができる。
尚、コンクリート１４を打設する際の生コン流入を妨げず、満遍なく表面鋼板間に打設できるようにリブ１６並びに内側鋼板１７の位置を考慮するのが好ましい。同じ目的でリブ１６や内面鋼板１７に生コン流入用の孔等を設けても良い。 According to the support mounting structure 10B of the second embodiment, the rigidity of the surface steel plates 12 and 13 can be increased by fixing the ribs 16 and the inner steel plate 17 to the inner surfaces of the surface steel plates 12 and 13. Thereby, compared with 1st Embodiment, the intensity | strength as the whole steel plate concrete structure 11 can be improved further.
In addition, it is preferable to consider the position of the rib 16 and the inner side steel plate 17 so that it can be poured evenly between the surface steel plates without disturbing the flow of raw concrete when the concrete 14 is placed. For the same purpose, the rib 16 or the inner steel plate 17 may be provided with a hole for injecting raw concrete.

（第３の実施の形態）
図３に示すように、第３の実施の形態によるサポート取り付け構造１０Ｃは、第２の実施の形態によるサポート取り付け構造１０Ｂと比較すると、リブ１８の構成が異なっている。尚、それ以外の構成は、第２の実施の形態と同じであるため、同じ符号を用い、ここでは説明を省略する。 (Third embodiment)
As shown in FIG. 3, the support mounting structure 10C according to the third embodiment is different in the configuration of the ribs 18 from the support mounting structure 10B according to the second embodiment. Since the other configuration is the same as that of the second embodiment, the same reference numerals are used and description thereof is omitted here.

リブ１８は、断面Ｌ型形状を有する複数のアングル材が格子状に組まれたものであって、表面鋼板１２，１３の内面全体に延在するようにしてそれぞれ固定されている。また第２実施形態と同様に、リブ１８の先端に固定して、表面鋼板１２，１３と略平行に配置された内側鋼板１７が設けられている。尚、リブ１８は、縦方向に延びる複数のアングル材と横方向に延びる複数のアングル材とを上下２段に積み上げることによって格子状に組まれている。   The ribs 18 are made of a plurality of angle members having an L-shaped cross section assembled in a lattice shape, and are fixed so as to extend over the entire inner surfaces of the surface steel plates 12 and 13. Further, as in the second embodiment, an inner steel plate 17 is provided which is fixed to the tip of the rib 18 and arranged substantially parallel to the surface steel plates 12 and 13. The ribs 18 are assembled in a lattice shape by stacking a plurality of angle members extending in the vertical direction and a plurality of angle members extending in the horizontal direction in two upper and lower stages.
