【考案の詳細な説明】 本考案は、内部にｐｃ鋼線を挿通、緊張し、長手方向に
数個の中空孔を形成した中空孔付プレストレストコンク
リート板の建て起しに用いる支持金具に関する。[Detailed Description of the Invention] The present invention relates to a support fitting used for erecting a prestressed concrete plate with hollow holes, in which a PC steel wire is inserted and tensioned, and several hollow holes are formed in the longitudinal direction.

この種のプレストレストコンクリート板（以下ｐｃ板と
記す）は、内部に配筋したｐｃ鋼線により、特に引張り
や曲げに対する強度が補強され、また中空孔により断熱
性、遮音性、耐火性等の面で優れていることから床や壁
等を構成する建築用材、構築用品として使用されている
。This type of prestressed concrete board (hereinafter referred to as PC board) is reinforced with internally reinforced PC steel wires, especially for tensile and bending strength, and has hollow holes to improve heat insulation, sound insulation, fire resistance, etc. Because of its excellent properties, it is used as a building material and construction supplies for making floors, walls, etc.

従来、このｐｃ板の建て起しは、横方向にワイヤーを掛
は渡し、このワイヤーをクレーン等で持ち上げて端面の
下辺を中心に、ここにあて木を施しながら回転させて行
っていた。Conventionally, this PC board was erected by passing a wire across it, lifting the wire with a crane, etc., and rotating the board around the lower edge of the board while placing battens there.

しかし、近時、ｐｃ板に断熱材等の柔らかい材質のもの
を張り合わせたものが開発され、この断熱材の端面の下
辺を中心に回転させれば、ここが崩れてしまう欠点が生
じた。However, recently, a PC board has been developed in which a soft material such as heat insulating material is pasted onto the PC board, which has the disadvantage that if the end face of the heat insulating material is rotated around the bottom edge, it will collapse.

また、通常このｐｃ板は基盤上に成形後、これを基盤と
してその上に重ねて成形されるため、両者間に全く隙間
がなく、これを建て起こす際にはバール等でこれを動か
す必要があり、この作業が面倒であるばかりでなく、傷
の発生の原因になってしまう欠点があった。In addition, since this PC board is usually molded on a base and then layered on top of that as a base, there is no gap between the two, so it is necessary to move it with a crowbar etc. when erecting it. However, this work is not only troublesome, but also has the drawback of causing scratches.

本考案は上記に鑑み、ｐｃ根板間隙間なく積層されてい
ても、この建て起しを容易に行うことができ、また断熱
材等の柔らかい材質を張り合わせたものでも端面の下辺
を傷つけることなく確実に建て起しを行えるものを提供
せんとして案出されたものである。In view of the above, the present invention allows for easy erection even when the PC base plates are laminated with no gaps between them, and even when soft materials such as insulation materials are laminated together, without damaging the lower edge of the end surface. It was devised to provide something that could be reliably rebuilt.

以下、図示の実施例に基づいて本考案を詳細に説明する
と、１は垂直部１ａと水平部１ｂにより断面り字形に形
成された本体で、この垂直部１ａと水平部１ｂとの間に
は補強材２が取付けられている。Hereinafter, the present invention will be described in detail based on the illustrated embodiment. Reference numeral 1 denotes a main body formed in a cross-sectional shape by a vertical part 1a and a horizontal part 1b, and there is a space between the vertical part 1a and the horizontal part 1b. Reinforcement material 2 is attached.

この本体１は後述のように、ＰＣＣ板肉建て起しの際、
その水平部の起端下辺１ｃを中心に回転するものであり
１、また断面り字形に形成したのはその水平部１ｂを広
くして安定させるとともに軽量化を図るためである。As will be described later, this main body 1 is
It rotates around the lower end 1c of the horizontal portion 1, and the reason why the cross section is formed into an angular shape is to widen the horizontal portion 1b for stability and to reduce the weight.

３は上記本体１の垂直部１ａにその水平部１ｂと反対方
向に突設したピンで、ｐｃ板Ａの中空孔Ｂに挿入自在に
形成されている。Reference numeral 3 denotes a pin which is provided on the vertical portion 1a of the main body 1 and protrudes in a direction opposite to the horizontal portion 1b, and is formed so as to be insertable into the hollow hole B of the PC board A.

また、このピン３には係止板４が取付けであるが、これ
はＰＣＣ板肉端面を支持し、この端面と本体１の垂直部
１ａとの間にあそびを持たせるためのものであり、本考
案では必ずしも必要ではなく、ｐｃ板Ａの端面を直接本
体１の垂直部１ａに接合させて、これを支持してもよい
。Also, a locking plate 4 is attached to this pin 3, and this is for supporting the end face of the PCC plate and providing a play between this end face and the vertical portion 1a of the main body 1. This is not always necessary in the present invention, and the end surface of the PC board A may be directly joined to the vertical portion 1a of the main body 1 to support it.

なお、図示の実施例ではＰＣＣ板肉コンクリート部Ａ１
に断熱材んを張り合わしたものを示している。In addition, in the illustrated embodiment, the PCC plate concrete part A1
The figure shows a structure in which insulation material is pasted on the surface.

次に、本考案の使用方法について説明すると、建て起し
金具を２個使用し、先ず、本体１に突設したピンをＰＣ
Ｃ板肉一端部両側の中空孔Ｂに夫夫挿入する。Next, to explain how to use the present invention, first, use two erecting metal fittings and connect the pin protruding from the main body 1 to the PC.
Insert the screw into the hollow hole B on both sides of one end of the C plate.

そしてＰＣＣ板肉他端を持ち上げることにより、本体１
の水平部１ｂの起端下辺ＩＣを中心に回転させこれを建
て起こすのである。Then, by lifting the other end of the PCC plate, the main body 1
The horizontal part 1b of the horizontal part 1b is rotated around the starting end lower side IC to raise it up.

このとき回転の中心は前述のように起端下辺ＩＣとなる
ので、ＰＣＣ板肉端面の下辺は崩れることなく、建て起
される。At this time, since the center of rotation is the lower edge IC as described above, the lower edge of the PCC plate end face is erected without collapsing.

本考案は上記のような構成であるので、ＰＣＣ板肉隙間
なく積層されていても、これを動かすことなく建て起こ
しを行うことができ、従って、この作業で傷等が発生す
ることがない。Since the present invention has the above-described configuration, even if the PCC plates are stacked without any gaps, it can be erected without moving the PCC plates, and therefore no damage will occur during this operation.

また、ＰＣＣ板肉建て起しの際の回転の中心が本体１の
水平部１ｂの起端下辺１ｃであるので、ＰＣＣ板肉端面
の下辺がこの回転の中心となってここが崩れてしまう従
来の欠点はなくなり、従って断熱材等の柔らかいものを
張り合わせたものでも、回転を防止しながら確実に建て
起こすことができ、更に、ＰＣＣ板肉中空孔Ｂを利用し
ているので従来のものをそのまま使用することができる
ばかりでなく、構造が簡単で、取扱いが容易である等の
諸効果がある。In addition, since the center of rotation when raising up the PCC plate is the lower edge 1c of the starting end of the horizontal portion 1b of the main body 1, the lower edge of the end face of the PCC plate becomes the center of rotation and collapses. This eliminates the drawbacks of , and therefore, even materials laminated with soft materials such as heat insulating materials can be reliably erected while preventing rotation.Furthermore, since the hollow hole B in the PCC plate is used, the conventional method can be used as is. Not only can it be used, but it also has various effects such as a simple structure and easy handling.
