Description
本発明は、波形に形成された鋼板で、床材や屋根材などとして使用されるデッキプレートに関する。 The present invention relates to a deck plate which is a corrugated steel plate and is used as a flooring material, a roofing material, or the like.
例えば、デッキプレートに空調ダクトを吊るして配設する場合、予めデッキプレートにインサートナットを取り付けてコンクリートを打設した後に、インサートナットに吊りボルトを取り付け（例えば、特許文献１参照。）、この吊りボルトで空調ダクトを吊るして配設していた。この際、設計上の空調ダクトの配設位置に合わせて、必要な箇所のみにインサートナットをデッキプレートに取り付けていた。また、インサートナットは、空調ダクトのみではなく、配線や配管などを配設する場合にも使用され、空調ダクトと同様に、設計上の配設位置に合わせて、必要な箇所のみにインサートナットをデッキプレートに取り付けていた。 For example, when the air conditioning duct is hung on the deck plate and arranged, an insert nut is attached to the deck plate in advance to cast concrete, and then a hanging bolt is attached to the insert nut (see, for example, Patent Document 1), and this suspension is performed. The air conditioning duct was hung with bolts. At this time, insert nuts were attached to the deck plate only at necessary locations according to the design arrangement position of the air conditioning duct. In addition, insert nuts are used not only for arranging air conditioning ducts but also for arranging wiring and piping, and like air conditioning ducts, insert nuts are placed only where necessary according to the design arrangement position. It was attached to the deck plate.
しかしながら、実際の施工現場においては、施工図の精度の悪さや、仕様の変更、空調ダクトなどの配設位置の変更などによって、予め取り付けられたインサートナットを使用できないケースが多く発生していた。例えば、その使用率は、５０％にも満たない場合があった。このため、空調ダクトなどの配設に際して、正しい配設位置に合わせて、現場で各業者が後打ちアンカーをデッキプレートに打設しなければならず、多大な時間と労力、費用を要していた。 However, at the actual construction site, there are many cases where the pre-installed insert nut cannot be used due to poor accuracy of the construction drawing, changes in specifications, changes in the arrangement position of the air conditioning duct, and the like. For example, the usage rate may be less than 50%. For this reason, when arranging the air-conditioning duct, etc., each contractor must place a post-installed anchor on the deck plate in accordance with the correct arrangement position, which requires a great deal of time, labor, and cost. It was.
しかも、デッキプレートにはコンクリートが既に打設されているため、後打ちアンカーの打設には多大な労力を要し、作業者の大きな負担となっていた。さらには、上方に向けて後打ちアンカーを打設しなければならないため、ローリングタワーなどを使用して安全性を確保する必要があり、多大な手間と費用を要していた。加えて、後打ちアンカーの打設によってコンクリートからの粉塵が飛散し、作業環境が悪化する、という問題があった。 Moreover, since concrete has already been cast on the deck plate, it takes a lot of labor to cast the post-casting anchor, which is a heavy burden on the operator. Furthermore, since it is necessary to place a post-launch anchor upward, it is necessary to ensure safety by using a rolling tower or the like, which requires a great deal of labor and cost. In addition, there is a problem that dust from the concrete is scattered by the placement of the post-casting anchor and the working environment is deteriorated.
そこでこの発明は、任意の位置に空調ダクトなどを配設可能なデッキプレートを提供することを目的とする。 Therefore, an object of the present invention is to provide a deck plate in which an air conditioning duct or the like can be arranged at an arbitrary position.

It differs from conventional deck plates in that it is possible.
このデッキプレート１は、従来のデッキプレートと同様に、鋼板（板材）が折り曲げられて、平坦部２から突出し断面が略三角形状で、筒状の谷部３が形成された波形のプレートである。すなわち、図２に示すように、鋼板が２つ折りされ、その先端側（折り目側）の断面が略三角形状に形成されて、筒状の谷部３が設けられている。この谷部３の三角形の頂部は、平坦部２側に位置し、底辺部３１が平坦部２と略平行になっている。ここで、図中符号３ａは、鋼板が２つ折りされて形成された隙間部である。 Similar to the conventional deck plate, the deck plate 1 is a corrugated plate in which a steel plate (plate material) is bent, protrudes from the flat portion 2, has a substantially triangular cross section, and has a tubular valley portion 3. .. That is, as shown in FIG. 2, the steel plate is folded in half, the cross section on the tip side (crease side) thereof is formed in a substantially triangular shape, and a tubular valley portion 3 is provided. The top of the triangle of the valley portion 3 is located on the flat portion 2 side, and the bottom portion 31 is substantially parallel to the flat portion 2. Here, reference numeral 3a in the drawing is a gap portion formed by folding the steel plate in half.
このような平坦部２と谷部３が、この実施の形態では、２つずつ形成され、一端側（図中左端）から順に、谷部３、平坦部２、谷部３、平坦部２が形成されている。また、一端側の谷部３に連接して、平坦部２と面一の接続面部２１が形成されている。一方、他端側（図中右端）の平坦部２の自由端部は、平坦部２に対して略垂直に谷部３側に曲げられて接続部２２が形成されている。そして、接続面部２１に隣接する隙間部３ａに、別のデッキプレート１の接続部２２を挿入することで、複数のデッキプレート１が接続・連結されるようになっている。 In this embodiment, two such flat portions 2 and two such valley portions 3 are formed, and the valley portion 3, the flat portion 2, the valley portion 3, and the flat portion 2 are formed in order from one end side (left end in the drawing). It is formed. Further, a connecting surface portion 21 that is flush with the flat portion 2 is formed so as to be connected to the valley portion 3 on one end side. On the other hand, the free end portion of the flat portion 2 on the other end side (right end in the drawing) is bent toward the valley portion 3 substantially perpendicular to the flat portion 2 to form the connecting portion 22. Then, by inserting the connecting portion 22 of another deck plate 1 into the gap portion 3a adjacent to the connecting surface portion 21, a plurality of deck plates 1 are connected and connected.
このようなデッキプレート１の板厚や平坦部２と谷部３の大きさ、高さ、および、谷部３と谷部３との間隔（第１の間隔）ｄ１は、デッキプレート１の上方（反谷部３側）に打設されるコンクリートの厚み・重量などに応じて、所定の強度、剛性が得られるように設定されている。また、この実施の形態では、それぞれ２つの平坦部２と谷部３を有する場合を例示しているが、打設されるコンクリートの厚みなどに応じて、異なる数の平坦部２と谷部３を有してもよい。 The thickness of the deck plate 1, the size and height of the flat portion 2 and the valley portion 3, and the distance (first interval) d1 between the valley portion 3 and the valley portion 3 are above the deck plate 1. It is set so that a predetermined strength and rigidity can be obtained according to the thickness and weight of the concrete placed on (the anti-valley portion 3 side). Further, in this embodiment, the case where the two flat portions 2 and the valley portions 3 are provided, respectively, is illustrated, but a different number of flat portions 2 and valley portions 3 are used depending on the thickness of the concrete to be cast and the like. May have.
このような谷部３の底辺部３１には、吊りボルト１０１を取り付けるためのボルト挿入孔（ボルト取付部）３３が、谷部３の長手方向に沿って所定の間隔で複数設けられている。すなわち、各谷部３の底辺部３１の幅方向の中央部に、底辺部３１を貫通するボルト挿入孔３３が、谷部３の長手方向に沿って第２の間隔（所定の間隔）ｄ２で複数形成されている。このボルト挿入孔３３の径は、吊りボルト１０１を挿入可能に設定されている。 A plurality of bolt insertion holes (bolt mounting portions) 33 for mounting the hanging bolts 101 are provided at the bottom portion 31 of the valley portion 3 at predetermined intervals along the longitudinal direction of the valley portion 3. That is, a bolt insertion hole 33 penetrating the bottom portion 31 is provided at the center of the bottom portion 31 of each valley portion 3 in the width direction at a second interval (predetermined interval) d2 along the longitudinal direction of the valley portion 3. Multiple are formed. The diameter of the bolt insertion hole 33 is set so that the suspension bolt 101 can be inserted.
ここで、第１の間隔ｄ１と第２の間隔ｄ２は、ボルト挿入孔３３がデッキプレート１の全面・四方にわたって略均等に配設され、任意・所望のボルト挿入孔３３に吊りボルト１０１を取り付けることで、任意・所望の位置に空調ダクトなどを吊って配設できるように設定されている。例えば、第１の間隔ｄ１は、２００〜３００ｍｍ程度に設定され、第２の間隔ｄ２は、２００ｍｍ程度に設定されている。このような間隔ｄ１、ｄ２は、同寸法にしてもよいし異なる寸法にしてもよい。なお、第１の間隔ｄ１は、上記のように、デッキプレート１に所定の強度、剛性が得られることも考慮して設定されている。 Here, in the first interval d1 and the second interval d2, the bolt insertion holes 33 are arranged substantially evenly over the entire surface and all four sides of the deck plate 1, and the suspension bolts 101 are attached to the arbitrary / desired bolt insertion holes 33. Therefore, it is set so that an air conditioning duct or the like can be hung and arranged at an arbitrary or desired position. For example, the first interval d1 is set to about 200 to 300 mm, and the second interval d2 is set to about 200 mm. Such intervals d1 and d2 may have the same dimensions or different dimensions. The first interval d1 is set in consideration of the fact that the deck plate 1 can obtain a predetermined strength and rigidity as described above.
さらに、このような谷部３の両方の斜辺部３２には、ボルト挿入孔３３に対向し吊りボルト１０１に吊りナット（ナット）１０２を締付可能な開口３４が複数設けられている。すなわち、図３に示すように、谷部３の両方の斜辺部３２に、略四角形で窓状の開口３４が、谷部３の長手方向においてボルト挿入孔３３と同位置に（ボルト挿入孔３３を臨むように）、第２の間隔ｄ２で複数形成されている。この開口３４の形状、大きさは、この開口３４から谷部３内に指やレンチを入れて、吊りナット１０２を締め付けられるように設定されている。ここで、この実施の形態では、谷部３の両方の斜辺部３２に開口３４が形成されているが、谷部３の大きさやデッキプレート１が設置される周囲環境などによっては、谷部３の一方の斜辺部３２のみに形成するようにしてもよい。 Further, both the hypotenuses 32 of the valley 3 are provided with a plurality of openings 34 facing the bolt insertion holes 33 and capable of tightening the suspension nuts 102 to the suspension bolts 101. That is, as shown in FIG. 3, a substantially quadrangular window-shaped opening 34 is provided at both oblique side portions 32 of the valley portion 3 at the same position as the bolt insertion hole 33 in the longitudinal direction of the valley portion 3 (bolt insertion hole 33). (To face), a plurality of them are formed at the second interval d2. The shape and size of the opening 34 are set so that a finger or a wrench can be inserted into the valley portion 3 from the opening 34 to tighten the hanging nut 102. Here, in this embodiment, openings 34 are formed in both hypotenuses 32 of the valley portion 3, but depending on the size of the valley portion 3 and the surrounding environment in which the deck plate 1 is installed, the valley portion 3 is formed. It may be formed only on one hypotenuse portion 32.
このような構成のデッキプレート１は、例えば、床材や屋根材として使用する場合、水平面状に延びるようにして隙間なく複数配置された状態で、上方に鉄筋が配設されてコンクリートが打設される。この状態では、複数のデッキプレート１で構成される床や屋根の全面にわたって、所定の間隔ｄ１、ｄ２で多数のボルト挿入孔３３が配設され（散りばめられ）ている。 When the deck plate 1 having such a configuration is used as a flooring material or a roofing material, for example, a plurality of deck plates 1 are arranged so as to extend in a horizontal plane without gaps, and reinforcing bars are arranged above and concrete is placed. Will be done. In this state, a large number of bolt insertion holes 33 are arranged (studded) at predetermined intervals d1 and d2 over the entire surface of the floor or roof composed of the plurality of deck plates 1.
そして、床や屋根（デッキプレート１）に空調ダクトなどを吊って配設する場合には、図４に示すように、まず、上端部側に吊りナット１０２を取り付けた吊りボルト１０１を、下方から所望のボルト挿入孔３３に挿入する。次に、このボルト挿入孔３３に対向する開口３４から谷部３内に指やレンチを入れて、吊りボルト１０１の上端から別の吊りナット１０２を螺合させ、２つの吊りナット１０２を締め付ける。これにより、２つの吊りナット１０２で谷部３の底辺部３１が挟持され、吊りボルト１０１が谷部３つまりデッキプレート１に取り付けられる。このようにして必要な数の吊りボルト１０１を必要な位置に取り付けて、空調ダクトなどを吊るものである。 Then, when suspending an air conditioning duct or the like on the floor or roof (deck plate 1), as shown in FIG. 4, first, a hanging bolt 101 having a hanging nut 102 attached to the upper end side is desired from below. It is inserted into the bolt insertion hole 33 of. Next, a finger or a wrench is inserted into the valley portion 3 from the opening 34 facing the bolt insertion hole 33, another hanging nut 102 is screwed from the upper end of the hanging bolt 101, and the two hanging nuts 102 are tightened. As a result, the bottom portion 31 of the valley portion 3 is sandwiched between the two suspension nuts 102, and the suspension bolt 101 is attached to the valley portion 3, that is, the deck plate 1. In this way, a necessary number of hanging bolts 101 are attached at necessary positions to hang an air conditioning duct or the like.
以上のように、このデッキプレート１によれば、波形のデッキプレート１の各谷部３に、ボルト挿入孔３３が第２の間隔ｄ２で複数設けられている。つまり、空調ダクトなどの配設位置に関わらず予め、縦横に所定の間隔ｄ１、ｄ２で複数のボルト挿入孔３３がデッキプレート１の全面・四方にわたって設けられている。このため、任意・所望のボルト挿入孔３３に吊りボルト１０１を取り付けることで、任意・所望の位置に容易に空調ダクトなどを配設することが可能となる。この結果、現場で後打ちアンカーを打設する必要がなくなり、作業者の負担を軽減して時間と労力、費用を削減することができるばかりでなく、安全性が向上するとともに、作業環境を改善することが可能となる。しかも、従来のデッキプレートに対して、ボルト挿入孔３３を谷部３に備えるだけであるため、簡易に低コストで構成することが可能となる。 As described above, according to the deck plate 1, a plurality of bolt insertion holes 33 are provided in each valley portion 3 of the corrugated deck plate 1 at a second interval d2. That is, a plurality of bolt insertion holes 33 are provided in advance on all four sides of the deck plate 1 at predetermined intervals d1 and d2 in the vertical and horizontal directions regardless of the arrangement position of the air conditioning duct or the like. Therefore, by attaching the suspension bolt 101 to the arbitrary / desired bolt insertion hole 33, it is possible to easily arrange the air conditioning duct or the like at the arbitrary / desired position. As a result, it is not necessary to place a post-installed anchor at the site, which not only reduces the burden on the operator and saves time, labor, and cost, but also improves safety and improves the working environment. It becomes possible to do. Moreover, since the bolt insertion hole 33 is only provided in the valley portion 3 as compared with the conventional deck plate, it can be easily configured at low cost.
また、ボルト取付部がボルト挿入孔３３で構成されているだけであるため、ボルト取付部を簡易に低コストで構成することが可能となる。従って、最終的に使用されないボルト取付部が生じたとしても、無駄な費用を抑制することが可能となる。 Further, since the bolt mounting portion is only composed of the bolt insertion hole 33, the bolt mounting portion can be easily configured at low cost. Therefore, even if a bolt mounting portion that is not used in the end occurs, it is possible to suppress unnecessary costs.
さらに、谷部３の斜辺部３２に開口３４が設けられ、この開口３４を介して吊りボルト１０１に吊りナット１０２を締め付けることができるようになっている。このため、ボルト挿入孔３３に吊りボルト１０１を容易、迅速かつ適切に取り付けることが可能となる。 Further, an opening 34 is provided in the hypotenuse portion 32 of the valley portion 3, and the suspension nut 102 can be tightened to the suspension bolt 101 through the opening 34. Therefore, the suspension bolt 101 can be easily, quickly, and appropriately attached to the bolt insertion hole 33.
以上、この発明の実施の形態について説明したが、具体的な構成は、上記の実施の形態に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があっても、この発明に含まれる。例えば、谷部３に吊りボルト１０１を取り付ける構造、方法（ボルト取付部）は、上記のものに限らない。例えば、谷部３の底辺部３１にボルト挿入孔３３に代ってネジ孔（雌ネジ）を形成し、このネジ孔に吊りボルト１０１を螺合させて取り付けてもよい。あるいは、谷部３の底辺部３１に吊り金具を取り付けて、この吊り金具に吊りボルト１０１を取り付けるようにしてもよい。 Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above-described embodiment, and even if there is a design change or the like within a range that does not deviate from the gist of the present invention. Included in the invention. For example, the structure and method (bolt attachment portion) for attaching the suspension bolt 101 to the valley portion 3 is not limited to the above. For example, a screw hole (female screw) may be formed in the bottom portion 31 of the valley portion 3 instead of the bolt insertion hole 33, and the suspension bolt 101 may be screwed into the screw hole for attachment. Alternatively, a hanging bracket may be attached to the bottom 31 of the valley portion 3, and the hanging bolt 101 may be attached to the hanging bracket.
