Description
【考案の詳細な説明】 この考案はデツキプレートの改良に係る。[Detailed explanation of the idea] This invention relates to an improvement of the deck plate.
例えば通例のデツキプレートは逆台形の上部開放形の溝
と、台形の山とが鋼板の長手方向に交互に折曲形成され
た異形の波付鋼板であって、Ｈ型鋼等の粱の上に載せら
れ、溝底が上面からアークスポット溶接等によって梁に
固着され、この上にコンクリートを打設して建造物の床
等を構築するのに使用される。For example, a common deck plate is an irregularly shaped corrugated steel plate in which inverted trapezoidal open-top grooves and trapezoidal peaks are alternately bent in the longitudinal direction of the steel plate, and is placed on top of a steel plate such as H-shaped steel. The groove bottom is fixed to the beam from the top by arc spot welding or the like, and concrete is placed on top of this to construct the floors of buildings.
しかしながら溝の部分に流しこまれるコンクリートは例
えば溝の深さ２５団のデツキプレートにおいては原子面
積に対し平均にして１２．５ｍｍの深さのコンクリート
量になり、厚さ１２−の床を打設するときはその約１０
％のコンクリート量に相当することになる。However, for example, in the case of a deck plate with a depth of 25 grooves, the concrete poured into the groove part will have an average depth of 12.5 mm based on the atomic area, and a floor with a thickness of 12 mm will be poured. Approximately 10 times when
% concrete amount.
この溝に打設されたコンクリートは床コンクリートの強
度を高める効果を殆んど有さないので、コンクリートを
それだけ余分に打つことになってコスト上問題になると
共に、床重量が増すことになるので梁や柱の強度をそれ
だけ大きくしなければならない。The concrete placed in these grooves has little effect on increasing the strength of the concrete floor, so an extra layer of concrete is needed, which poses a cost problem and increases the weight of the floor. The strength of beams and columns must be increased accordingly.
これに対して溝の上部を両側からよせて断面フラスコ形
の閉鎖形の溝を並列させて設けたデツキプレートが提案
されているが、溝にコンクリートが流れこまないように
頚部がしぼっであるため溶接用の電極棒をさしこめない
ので溝の底を梁に溶接固定することができず、やむを得
ず粱の間隔の長さのものをその都度切断して隣接する粱
と梁に両端を載せて端部において梁に溶接して固定する
はかなく、非能率かつ不経済であるほか、粱の間隔に切
断するのも余り短かくては不経済であるし、梁の間隔を
余り狭くはできないので長さの長いものを使用するよう
になる結果、必然的に板厚の厚いもの或いは溝の深さの
深い大形のデツキプレートにしか利用できなかった。For this purpose, a deck plate has been proposed in which closed grooves with a flask-shaped cross section are arranged in parallel with the upper part of the grooves pushed aside from both sides, but the neck is constricted to prevent concrete from flowing into the grooves. Since I couldn't insert the electrode rod for welding, I couldn't weld the bottom of the groove to the beam, so I had no choice but to cut the length of the groove between the wires each time and place both ends on the adjacent wire and beam. Welding and fixing to the beams at the ends is ephemeral, inefficient and uneconomical, and it is also uneconomical if the beams are cut at intervals that are too short, and it is not possible to make the intervals between the beams too narrow. As a result of the use of longer plates, they could only be used for thick plates or large deck plates with deep grooves.
本考案は上記のような問題点を解決するデツキプレート
を提供することを目的とし、鋼板に溝と山とが交互に平
行に折曲形成されたデツキプレートにおいて上部開放形
の溝と溝の間に複数列の上部閉鎖形の溝が形成されてい
ることを特徴とするデツキプレートに係る。The purpose of the present invention is to provide a deck plate that solves the above-mentioned problems.The purpose of this invention is to provide a deck plate in which grooves and peaks are bent alternately and parallel to each other on a steel plate. The present invention relates to a deck plate characterized in that a plurality of rows of closed-top grooves are formed in the deck plate.
次に添付図面に示す実施例について説明する。Next, embodiments shown in the accompanying drawings will be described.
図示のものは両端および中央に上部開放形の溝１が折曲
形成されており、開放形の溝と溝との間に頚部２が絞ら
れて断面にフラスコ形の上部閉鎖形の溝３が二列設けら
れているデツキプレート４である。In the illustrated example, a groove 1 with an open top is formed by bending at both ends and the center, and a neck 2 is squeezed between the open grooves to form a flask-shaped groove 3 with a closed top in cross section. The deck plates 4 are provided in two rows.
左右の両端の溝１は通例のとおり溝の片側の壁が一部欠
けており、一点鎖線で示したように隣接のデツキプレー
ト５の側端部の溝と組合せて梁６上に固定される。The grooves 1 at both left and right ends have a part of the wall on one side of the groove missing as usual, and are fixed onto the beam 6 by combining with the grooves at the side ends of the adjacent deck plate 5, as shown by the dashed line. .
デツキプレート４は開放形溝１と閉鎖形溝３との組合せ
であるから開放形溝の上方から溝１の底をアークスポッ
ト溶接或いは焼抜き栓溶接で梁の上面に溶接することが
できる。Since the deck plate 4 is a combination of an open groove 1 and a closed groove 3, the bottom of the groove 1 can be welded to the upper surface of the beam from above the open groove by arc spot welding or burnout plug welding.
従って長さは通例の長さのものを使用できるようになる
。Therefore, it becomes possible to use a length that is customary.
デツキプレートの幅は通例的６００〜７０−であるから
左右両側端部と中央部で粱に固定すればばたつくことが
ないし、また梁の横座屈に対しても充分に強度を発揮で
きる。The width of the deck plate is usually 600 to 70 mm, so if it is fixed to the wire at both left and right ends and the center, it will not flap and will have sufficient strength against lateral buckling of the beam.
コンクリートが打設される溝はこの例のデツキプレート
では３列の溝のうち１列だけなので従来の開放形溝だけ
のタイプのものに比して溝に打設されるコンクリートの
量はｌ／３になり、溝の深さ２５鴫として床面積に対し
て平均１．９＝厚に過ぎず、例えば１２−厚にコンクリ
ートで床を打設する場合は僅か約１．６％に相当するだ
けであり、無視できるほどでコスト上大きな利益になる
等実用上火きな効果が得られる。Since only one of the three rows of grooves is placed in the deck plate in this example, the amount of concrete poured into the groove is 1/1 compared to the conventional type with only open grooves. 3, and if the depth of the groove is 25mm, the average thickness is only 1.9% of the floor area, and for example, if the floor is poured with concrete to a thickness of 12mm, it corresponds to only about 1.6%. This is a negligible cost, but has great practical effects, such as a large cost advantage.
