【考案の詳細な説明】
（産業上の利用分野）
この考案は耐力、特に曲げ耐力を高めた合成梁
に関するものである。[Detailed description of the invention] (Field of industrial application) This invention relates to a composite beam with increased strength, especially bending strength.
（考案が解決しようとする問題点）
鉄骨造における合成梁では、スラブは普通型
枠、デツキプレートのいずれの場合も全面に亘つ
て等厚であり、しかも通常薄肉であるため鉄筋を
多く配筋すること、また太い鉄筋を入れることが
難しく、合成梁としての耐力、特に曲げ耐力に限
界があるのが実情である。(Problem that the invention aims to solve) In composite beams in steel structures, the slab has the same thickness over the entire surface, whether it is ordinary formwork or deck plate, and is usually thin, so many reinforcing bars are arranged. The reality is that it is difficult to do so, and it is difficult to insert thick reinforcing bars, and there is a limit to the strength of composite beams, especially the bending strength.
この考案はこうした合成梁の実情を踏まえ、耐
力の向上を図る目的からなされもので、合成梁を
構成する一部のスラブを肉厚にし、ここの十分な
配筋をすることによりこれを解決しようとするも
のである。 This idea was created based on the actual situation of composite beams, with the aim of improving their strength.This problem could be solved by making some of the slabs that make up composite beams thicker, and by arranging sufficient reinforcement there. That is.
（問題点を解決するための手段）
本考案では鉄骨梁上部のスラブ厚を他より部分
的に大きくし、この部分に十分な数の鉄筋を入れ
ることによつて耐力の向上を図る。(Means for solving the problem) In the present invention, the thickness of the slab in the upper part of the steel beam is made larger than in other parts, and a sufficient number of reinforcing bars are inserted in this part to improve the strength.
スラブの厚肉部には鉄筋を上下２段に、その周
囲にスターラツプを配筋し、更にスターラツプの
内側にPC鋼材を配置する。 In the thick part of the slab, reinforcing bars are placed in two layers, upper and lower, and stirrups are arranged around the reinforcing bars, and prestressing steel is placed inside the stirrups.
PC鋼材は柱間に懸垂線状に配置されて緊張さ
れ、これによつて合成梁としてのスラブ部分に懸
垂力が与えられ、曲げ耐力が高められる。 The prestressing steel materials are arranged in a catenary line between the columns and are tensioned, giving suspension force to the slab section as a composite beam and increasing its bending strength.
（実施例）
以下本考案の一実施例を示す図面に基づいて説
明する。(Embodiment) An embodiment of the present invention will be described below based on the drawings.
この考案の合成梁Ａは第１図に示すように鉄骨
梁１の上部のスラブ２を厚肉にし、ここに上端筋
３ａ、下端筋３ｂ、スターラツプ４及びPC鋼材
５を配筋してなるものである。 As shown in Fig. 1, the composite beam A of this invention is made by thickening the slab 2 at the top of the steel beam 1, and arranging upper end reinforcements 3a, lower end reinforcements 3b, stirrups 4, and prestressing steel materials 5. It is.
スラブ２の厚肉部２ａは鉄骨梁１上の両側に一
定の幅を有し、この幅は目標の耐力に応じて決め
られる。 The thick portion 2a of the slab 2 has a constant width on both sides of the steel beam 1, and this width is determined according to the target proof strength.
この厚肉部２ａに所定のかぶり厚を確保して複
数列の上端筋３ａ、下端筋３ｂ及びスターラツプ
４を配筋するとともに、スターラツプ４の内側に
PC鋼材５を配置する。PC鋼材５は厚肉部２ａの
中心線の両側に入れられる。 A predetermined cover thickness is ensured in this thick part 2a, and multiple rows of upper end reinforcements 3a, lower end reinforcements 3b, and stirrups 4 are arranged, and inside of the stirrup 4.
Place the PC steel material 5. The PC steel material 5 is placed on both sides of the center line of the thick walled portion 2a.
またPC鋼材５は第２図に示すように柱６，６
間に、厚肉部２ａをPC梁とみなしたときの引張
側に懸垂線状に配置されてプレストレス力を導入
される。 In addition, the PC steel material 5 is used for columns 6 and 6 as shown in Fig. 2.
In the meantime, when the thick wall portion 2a is regarded as a PC beam, it is arranged in a catenary shape on the tensile side, and a prestress force is introduced.
なお、鉄骨梁１上の上部フランジにはスタツド
ジベル７が取り付けられる。 Note that a stud dowel 7 is attached to the upper flange on the steel beam 1.
（考案の効果）
この考案は以上の通りであり、合成梁を構成す
るスラブを厚肉にし、ここに十分な配筋を施すも
のであるため合成梁としての耐力を高めることが
でき、またPC鋼材の緊張により懸垂力が加えら
れるため特に曲げ耐力の向上を図ることが可能で
ある。(Effects of the idea) This idea is as described above.The slab that makes up the composite beam is thickened and sufficient reinforcement is placed here, which increases the strength of the composite beam. Since a suspension force is applied by tensioning the steel material, it is possible to particularly improve the bending strength.
