Description

本発明は、少なくとも一方の表面に鋼板を有するコンクリート構造の内部に、強度メンバーとなる根太材として細長い鋼材を埋設して施工される鋼板コンクリート構造体に形成した埋設電路、その埋設電路にケーブルを埋設する方法および前記鋼板コンクリート構造体に埋設電路を形成する方法に関する。   The present invention relates to an embedded electric circuit formed in a steel plate concrete structure constructed by embedding a long and narrow steel material as a joist as a strength member inside a concrete structure having a steel plate on at least one surface, and a cable to the embedded electric circuit. The present invention relates to a method of burying and a method of forming a buried electric circuit in the steel plate concrete structure.

ビルや高層マンション、工場建物などの大型建築物、あるいは橋梁などの構造体は鉄筋コンクリート構造（ＲＣ構造）または鉄骨・鉄筋コンクリート構造（ＳＲＣ構造）により建設される場合が多い。これら構造物には電気設備や通信設備のケーブル挿通用の電線管からなる電路がコンクリート中に敷設される。   Large buildings such as buildings, high-rise condominiums, and factory buildings, or structures such as bridges are often constructed with a reinforced concrete structure (RC structure) or a steel frame / reinforced concrete structure (SRC structure). In these structures, an electric circuit composed of a conduit for inserting a cable for electric equipment and communication equipment is laid in the concrete.

例えばビルや高層マンションなどの多層階建築物では、床スラブに電線管からなる電路が埋設され、その埋設電路にケーブルを敷設することが多い。鉄筋コンクリート構造の場合は、床の上部と下部にそれぞれ補強用の鉄筋が配設され、それら鉄筋の中間部に電線管が埋設されるが、この場合は上下の鉄筋の間に比較的大きな電線管敷設用のスペースが取れるので問題はない。一方、少なくとも一方の表面に鋼板を有するコンクリート構造の内部に、Ｈ型鋼を補強材としてコンクリート中に埋設した鋼板コンクリート構造（ＳＣ構造）が最近開発され注目されている。   For example, in a multi-story building such as a building or a high-rise apartment, an electric circuit composed of a conduit is embedded in a floor slab, and a cable is often laid in the embedded electric circuit. In the case of a reinforced concrete structure, reinforcing bars are arranged at the upper and lower parts of the floor, respectively, and a conduit is buried in the middle of the reinforcing bars. In this case, a relatively large conduit is placed between the upper and lower reinforcing bars. There is no problem because there is space for laying. On the other hand, a steel plate concrete structure (SC structure) in which H-shaped steel is embedded in concrete as a reinforcing material inside a concrete structure having a steel plate on at least one surface has recently been developed and attracting attention.

鋼板コンクリート構造に電路を埋設するには、鉄筋コンクリート構造の場合と同様に、Ｈ型鋼より上方の間隙に電線管を埋設する方法が考えられる。図３は鋼板コンクリート構造体で形成した床スラブに対し、上記考え方に基づいて（常法により）電線管を埋設した場合を示す縦断面図である。この例では鋼板コンクリート構造体１の上面が上階の床２を構成し、下面が下階の天井３を構成する。鋼板コンクリート構造体１の上部には鉄筋４が上端筋として縦横に配置され、下部にＨ型鋼からなる複数の鋼材５が強度メンバーとなる根太材として所定間隔で配置される。そして鉄筋４と鋼材５の間隙を埋設電路のスペースとして利用し、該部分に電線管６を埋設して埋設電路、すなわちケーブルを挿通できる埋設された電気配線経路を形成する。   In order to embed the electric circuit in the steel plate concrete structure, as in the case of the reinforced concrete structure, a method of burying the electric conduit in the gap above the H-shaped steel can be considered. FIG. 3 is a longitudinal sectional view showing a case where a conduit tube is embedded in a floor slab formed of a steel plate concrete structure based on the above-described concept (by a conventional method). In this example, the upper surface of the steel plate concrete structure 1 constitutes the upper floor 2 and the lower surface constitutes the lower ceiling 3. Reinforcing bars 4 are arranged vertically and horizontally at the upper part of the steel plate concrete structure 1, and a plurality of steel materials 5 made of H-shaped steel are arranged at predetermined intervals as joists as strength members at the lower part. And the space | interval of the reinforcing bar 4 and the steel material 5 is utilized as a space of the buried electric circuit, and the electric pipe 6 is buried in this portion to form an embedded electric circuit, that is, an embedded electric wiring path through which the cable can be inserted.

図３のように埋設電路を形成するには、先ず鋼板に根太材としての鋼材５を接合し且つ多数のスタッド５ａが溶接固定されたものを、既に設置した壁部の上に固定し、その上方に電線管６を敷設する。さらにその上方に鉄筋４を設定し、最後にコンクリート８を打設する。そしてコンクリート８が硬化すると図３のように電線管６が埋設された鋼板コンクリート構造体１が完成する。   In order to form an embedded electric circuit as shown in FIG. 3, first, a steel member 5 as a joist member is joined to a steel plate and a number of studs 5a are welded and fixed to the already installed wall portion. The conduit 6 is laid on the upper side. Further, a reinforcing bar 4 is set above, and finally concrete 8 is placed. And when the concrete 8 hardens | cures, the steel plate concrete structure 1 with which the electric pipe 6 was embed | buried like FIG. 3 will be completed.

しかし鋼板コンクリート構造体１は鉄筋４と鋼材５の間隔が狭いので電線管の配設スペースの確保が難しい。そのため埋設電路の形成に多くの手間と煩雑さを伴い、場合によっては埋設施工が困難な場合もある。さらに、完成した鋼板コンクリート構造体からなるスラブに例えば上側の床から後打ちアンカーなどを打込む場合、床位置から電線管６までの距離が短いため、アンカーの先端が上部の鉄筋４の間隙を通過して電線管６またはその中に挿通したケーブルを損傷することもある。   However, since the steel plate concrete structure 1 has a narrow space between the reinforcing bar 4 and the steel material 5, it is difficult to secure a space for arranging the conduit. Therefore, the formation of the buried electric circuit involves a lot of labor and complexity, and in some cases, the buried construction may be difficult. Further, when a post-casting anchor or the like is driven into the slab made of a steel plate concrete structure from the upper floor, for example, the distance from the floor position to the conduit 6 is short, so the tip of the anchor has a gap between the upper reinforcing bars 4. It may damage the conduit 6 or the cable inserted therethrough.

そこで本発明は係る諸問題を解決することを課題とし、そのための新しい埋設電路を提供することを目的とする。また本発明は前記埋設電路を利用したケーブルの埋設方法を提供することも目的とする。さらに本発明は前記埋設電路の形成方法を提供することも目的とする。   Then, this invention makes it a subject to solve the various problems which concern, and it aims at providing the new buried electrical circuit for it. Another object of the present invention is to provide a cable burying method using the buried electric circuit. Another object of the present invention is to provide a method for forming the buried electric circuit.

前記課題を解決する本発明に係る埋設電路は、少なくとも一方の表面に鋼板を有するコンクリート構造の内部に、強度メンバーとなる根太材として細長い鋼材を埋設してなる鋼板コンクリート構造体に形成した埋設電路である。そして、前記鋼材が内部に細長い閉鎖空間を形成する管状鋼とされ、該管状鋼には閉鎖空間と鋼板コンクリート構造体の外部を連通する連通部が設けられると共に、その閉鎖空間に埋設電路が形成されることを特徴とする（請求項１）。   An embedded electric circuit according to the present invention that solves the above-described problems is an embedded electric circuit formed in a steel plate concrete structure in which a long steel material is embedded as a joist member serving as a strength member inside a concrete structure having a steel plate on at least one surface. It is. The steel material is a tubular steel that forms an elongated closed space inside, and the tubular steel is provided with a communication portion that communicates the closed space and the outside of the steel plate concrete structure, and an embedded electric circuit is formed in the closed space. (Claim 1).

上記埋設電路において、前記管状鋼に分岐電路を連通することができる（請求項２）。   In the buried electric circuit, a branch electric circuit can be communicated with the tubular steel (claim 2).

上記いずれかの埋設電路において、前記連通部は前記管状鋼に連結した接続ボックスにより構成することができる（請求項３）。   In any one of the above-described buried electric circuits, the communication part can be constituted by a connection box connected to the tubular steel (Claim 3).

また前記課題を解決する本発明に係るケーブル埋設方法は、前記いずれかの埋設電路にケーブルを埋設する方法であって、前記連通部を利用してケーブルを鋼板コンクリート構造体の外部から埋設電路に引き込み、または埋設電路からケーブルを鋼板コンクリート構造体の外部に引き出すことを特徴とする（請求項４）。   Moreover, the cable burying method according to the present invention for solving the above-mentioned problem is a method of burying a cable in any one of the buried electric circuits, and the cable is transferred from the outside of the steel plate concrete structure to the buried electric circuit using the communication portion. The cable is drawn out or pulled out from the buried electric circuit to the outside of the steel plate concrete structure (claim 4).

さらに前記課題を解決する本発明に係る埋設電路の形成方法は、少なくとも一方の表面に鋼板を有するコンクリート構造の内部に、強度メンバーとなる根太材として細長い管状鋼を埋設して施工される鋼板コンクリート構造体に埋設電路を形成する方法である。そして、前記鋼材として内部に細長い閉鎖空間を形成する管状鋼を用い、その管状鋼の所定位置に閉鎖空間と鋼板コンクリート構造体の外部を連通する連通部を設け、その連通部を残して前記管状鋼をコンクリートに埋設することにより、前記閉鎖空間に連通部を介して鋼板コンクリート構造体の外部と連通する埋設電路を形成することを特徴とする（請求項５）。   Furthermore, the method for forming an embedded electric circuit according to the present invention that solves the above-mentioned problem is a steel plate concrete that is constructed by embedding a long and narrow tubular steel as a joist material to be a strength member inside a concrete structure having a steel plate on at least one surface This is a method of forming an embedded electric circuit in a structure. And the tubular steel which forms the elongate closed space inside is used as said steel material, The communication part which connects the closed space and the exterior of a steel plate concrete structure is provided in the predetermined position of the tubular steel, The said tubular part is left leaving the communication part By embedding steel in concrete, a buried electric circuit communicating with the outside of the steel plate concrete structure is formed in the closed space via a communicating portion (Claim 5).

本発明に係る鋼板コンクリート構造体の埋設電路は、内部に細長い閉鎖空間を形成する管状鋼を使用し、その管状鋼に閉鎖空間と鋼板コンクリート構造体の外部を連通する連通部を設け、その閉鎖空間に埋設電路を形成したので、従来のように電線管を埋設するスペースが不十分な鋼板コンクリート構造体であっても容易に埋設電路を形成できる。   The buried electric circuit of the steel plate concrete structure according to the present invention uses tubular steel that forms an elongated closed space inside, and the tubular steel is provided with a communication portion that communicates the closed space and the outside of the steel plate concrete structure. Since the embedded electric circuit is formed in the space, the embedded electric circuit can be easily formed even in the case of a steel plate concrete structure in which the space for embedding the electric conduit is insufficient as in the prior art.

また鋼板コンクリート構造体における上方の床などから後打ちアンカーを打込む場合、ケーブルは床などから比較的大きな距離が確保された電路に挿通されているので、アンカーの先端で該ケーブルが損傷を受けるおそれれもない。さらに埋設電路は電線管より断面空間を大きく取れる管状鋼の閉鎖空間に形成されるので、ケーブルの敷設や更新作業が容易になる。また１つの埋設電路に多数のケーブルを並行して敷設できる。さらには鋼板コンクリート構造体に電線管が存在しないので、鋼板コンクリート構造体の強度低下等を防止でき、施工コストも低減できる。   In addition, when a post-fixed anchor is driven from an upper floor or the like in a steel concrete structure, the cable is damaged by the anchor tip because the cable is inserted through an electric circuit that is secured at a relatively large distance from the floor or the like. There is no fear. Furthermore, since the buried electric circuit is formed in a closed space of tubular steel that can take a larger cross-sectional space than the conduit, cable laying and renewal work can be facilitated. In addition, a large number of cables can be laid in parallel in one buried electric circuit. Furthermore, since there is no electric conduit in the steel plate concrete structure, it is possible to prevent a decrease in the strength of the steel plate concrete structure and to reduce the construction cost.

上記埋設電路において、前記管状鋼に分岐電路を連通する場合は、ケーブルの敷設ルートの自由度を大きくできると共に、ケーブルの敷設や更新等をより容易に行うことができる。さらに前記連通部を前記管状鋼に連結した接続ボックスにより構成する場合は、ケーブルの敷設や更新等をより容易に行うことができると共に、管状鋼に複雑な加工等を行う必要がなくなる。   In the buried electric circuit, when the branch electric circuit is communicated with the tubular steel, the degree of freedom of the cable laying route can be increased, and the cable can be laid or renewed more easily. Further, when the communication part is constituted by a connection box connected to the tubular steel, the cable can be laid or renewed more easily, and complicated processing or the like is not required for the tubular steel.

また本発明に係るケーブル埋設方法によれば、ケーブルの敷設や更新等を容易に行うことができ、１つの埋設電路に多数のケーブルを並行して敷設することもできる。さらに本発明に係る鋼板コンクリート構造体における埋設電路の形成方法によれば、前記効果を奏する埋設電路を容易に形成することができる。   Moreover, according to the cable embedment method according to the present invention, cable laying and updating can be easily performed, and a large number of cables can be laid in parallel in one buried electric circuit. Furthermore, according to the method for forming an embedded electric circuit in a steel plate concrete structure according to the present invention, an embedded electric circuit that exhibits the above-described effects can be easily formed.

次に本発明の最良の実施形態を図面により説明する。図１は本発明に係る埋設電路を形成した鋼板コンクリート構造体の縦断面図であり、図２は図１のＡ−Ａ断面説明図（コンクリート部分を省略）である。この例では床スラブを構成する鋼板コンクリート構造体１の上面は建物の上階の床２を構成し、下面は例えば下階の天井３を構成する。   Next, the best embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a steel plate concrete structure in which a buried electric circuit according to the present invention is formed, and FIG. 2 is an AA sectional explanatory view of FIG. 1 (concrete portion omitted). In this example, the upper surface of the steel plate concrete structure 1 constituting the floor slab constitutes the floor 2 of the upper floor of the building, and the lower surface constitutes the ceiling 3 of the lower floor, for example.

鋼板コンクリート構造体１の上部に鉄筋４が上端筋としてメッシュ状に設定（配置）され、下部に断面が方形の複数の細長い管状鋼１０が強度メンバーを構成する根太材として配置される。なお本実施形態では隣接する管状鋼１０の間の一部において、強度は有しないがケーブルを挿通できる管もしくは電線管のような分岐電路１１ａを連通している。しかし場合によっては分岐電路１１ａを省略することもできる。   Reinforcing bars 4 are set (arranged) as upper end bars in the upper part of the steel plate concrete structure 1, and a plurality of elongated tubular steels 10 having a square cross section are arranged in the lower part as joists constituting strength members. In this embodiment, a part between adjacent tubular steels 10 communicates with a branching electric circuit 11a such as a pipe or a conduit that does not have strength but can be inserted with a cable. However, in some cases, the branch circuit 11a can be omitted.

管状鋼１０の内部は細長い閉鎖空間を形成し、その閉鎖空間がケーブルを敷設する埋設電路１１とされる。そしてケーブルの引き込み部分と引き出し部分、本例では管状鋼１０及びそれと分岐電路１１ａの連通部分等に、前記埋設電路１１と鋼板コンクリート構造体１の外部を連通する連通部１２が設けられる。連通部１２は管状鋼１０に連結した接続ボックス１３を含む。その接続ボックス１３は鋼板パネル７を介して管状鋼１０に連通する。なお管状鋼１０と接続ボックス１３の接続部分を予め製造工場などにおいて形成しプレハブ化することができる。そのように接続部分をプレハブ化すると、現場での管状鋼１０と接続ボックス１３の接続精度が向上し、施工効率を高めることができる。   The inside of the tubular steel 10 forms an elongated closed space, and the closed space serves as a buried electric path 11 for laying a cable. And the connection part 12 which connects the said underground electric circuit 11 and the exterior of the steel-plate concrete structure 1 is provided in the drawing part and drawing part of a cable, and the connection part of the tubular steel 10 and this and the branch electric circuit 11a in this example. The communication part 12 includes a connection box 13 connected to the tubular steel 10. The connection box 13 communicates with the tubular steel 10 via the steel plate panel 7. In addition, the connection part of the tubular steel 10 and the connection box 13 can be previously formed in a manufacturing factory etc., and can be prefabricated. If the connection portion is prefabricated in this manner, the connection accuracy between the tubular steel 10 and the connection box 13 at the site is improved, and the construction efficiency can be increased.

図１に示すように、接続ボックス１３に接した部分の管状鋼１０にケーブル貫通孔１４が形成され、さらにその管状鋼１０に連通する分岐電路１１ａの部分にもケーブル貫通孔１４が形成される。また、接続ボックス１３の外側には露出電線管１５が接続される。なお図１の一番右側の位置における管状鋼１０には接続ボックス１３が接続されていないが、該部分の管状鋼１０には図示のように予備用としてケーブル貫通孔１４を形成しておくことができる。   As shown in FIG. 1, a cable through hole 14 is formed in a portion of the tubular steel 10 in contact with the connection box 13, and a cable through hole 14 is also formed in a portion of the branch electric circuit 11 a communicating with the tubular steel 10. . An exposed conduit 15 is connected to the outside of the connection box 13. In addition, although the connection box 13 is not connected to the tubular steel 10 in the rightmost position of FIG. 1, the cable through-hole 14 is formed in the tubular steel 10 of this part as a reserve as shown in the figure. Can do.

図１において、例えば左側の露出電線管１５より接続ボックス１３に引き込まれたケーブル１６は、そこからケーブル貫通孔１４を介し左側の管状鋼１０に入る。そして、その左側の管状鋼１０の埋設電路１１を図２に示す如く一端から他端に導かれ、左側の管状鋼１０に連通する分岐電路１１ａを経て中央の管状鋼１０に入り、そこから図１の如く下側のケーブル貫通孔１４を介して中央の露出電線管１５から引き出される。なお、ケーブル１６を一つの管状鋼１０内のみを一端から他端に挿通して、その両端より露出電線管に接続してもよい。さらには、図２において、ケーブル１６を中央の管状鋼１０内を図の上方に導き分岐電路１１ａを介して右の管状鋼１０内に導いてもよい。   In FIG. 1, for example, the cable 16 drawn into the connection box 13 from the left exposed conduit 15 enters the left tubular steel 10 through the cable through hole 14. Then, the buried electrical circuit 11 of the left tubular steel 10 is guided from one end to the other end as shown in FIG. 2, and enters the central tubular steel 10 through the branch electrical circuit 11a communicating with the left tubular steel 10, and from there As shown in FIG. 1, it is pulled out from the central exposed conduit 15 through the lower cable through hole 14. Note that the cable 16 may be inserted through only one tubular steel 10 from one end to the other end and connected to the exposed conduit from both ends. Further, in FIG. 2, the cable 16 may be guided in the middle tubular steel 10 upward in the figure and led into the right tubular steel 10 through the branch electric circuit 11 a.

図１のように埋設電路１１を形成するには、先ず管状鋼１０およびスタッド５ａを溶接接合した鋼板パネル７を図示しない壁部の上に固定し、次に管状鋼１０の上側の所望位置に分岐電路１１ａを固定する。次に分岐電路１１ａの上方の所定位置に鉄筋４を設定し、最後にコンクリート８を打設してそれらを埋設することにより、埋設電路１１が形成された鋼板コンクリート構造体１が完成する。なおコンクリート打設前に埋設電路１１および分岐電路１１ａの所望ルートにメッセンジャーワイヤを挿通しておくことが望ましい。   In order to form the buried electric circuit 11 as shown in FIG. 1, first, the steel plate panel 7 to which the tubular steel 10 and the stud 5 a are welded and joined is fixed on a wall portion (not shown), and then the desired position on the upper side of the tubular steel 10. The branch circuit 11a is fixed. Next, the steel bar concrete structure 1 in which the embedded electric circuit 11 is formed is completed by setting the reinforcing bar 4 at a predetermined position above the branch electric circuit 11a, and finally placing concrete 8 and embedding them. In addition, it is desirable to insert a messenger wire into a desired route of the buried electric circuit 11 and the branch electric circuit 11a before placing concrete.

次に上記のように形成した埋設電路１１に図２のようにケーブル１６を埋設する方法を説明する。先ずケーブル１６の先端を埋設電路１１に予め引き込んだメッセンジャーワイヤの後端に接続し、次にメッセンジャーワイヤを引き出すことによりケーブル１６が埋設電路１１の所定経路に埋設される。このようにケーブル１６は補強用の管状鋼１０に形成した埋設電路１１に沿って敷設されるので、前記のような効果を奏する。   Next, a method of burying the cable 16 as shown in FIG. 2 in the buried electric circuit 11 formed as described above will be described. First, the front end of the cable 16 is connected to the rear end of a messenger wire previously drawn into the embedded electric circuit 11, and then the cable 16 is embedded in a predetermined path of the embedded electric circuit 11 by pulling out the messenger wire. Thus, since the cable 16 is laid along the embedded electric circuit 11 formed in the tubular steel 10 for reinforcement, the above-described effects are exhibited.

本発明の埋設電路等は鋼板コンクリート構造物にケーブルを敷設する分野に利用できる。   The buried electric circuit or the like of the present invention can be used in the field of laying a cable on a steel plate concrete structure.
