した補強材締付部付き係止具に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking member with a reinforcing member fastening portion, and more particularly to a locking member with a reinforcing member fastening portion suitable for use in a concrete form or the like.

手に入り、比較的安価のものである。2. Description of the Related Art Conventionally, a U-shaped locking member (conventional example) called a U-clip as shown in FIG. 6 has been used for a steel concrete form or the like. This is a convenient locking tool that strongly supports and locks the back of the formwork at the required points.The material is a low-carbon or medium-carbon steel bar that can be obtained anywhere, and is relatively inexpensive. Things.

合せ型枠全体の強度が不足し勝ちであるため、しばしば
型枠背面に１対の鋼管などの補強材を数箇もしくは数１
０箇の型枠に井桁状に渡して用いるのが普通であった。Usually, when a large-sized concrete structure is manufactured, a large number of unit forms having a unit weight of about 10 to 30 kg are often added to each other for handling. In this case, since the strength of the combined formwork as a whole tends to be insufficient, it is often necessary to provide a pair of reinforcing materials such as a pair of steel pipes on the backside of the formwork.
It was usual to use it by passing it in a girder shape to zero formwork.

【０００４】このような鋼製型枠の一般的な組立固め方
法は、大別すると型枠と補強材の締付方法の違いで２つ
ある。ただし型枠係止具および係止方法自体は同一であ
る。[0004] There are two general methods of assembling and hardening such a steel formwork in terms of the method of fastening the formwork and the reinforcing material. However, the form locking device and the locking method itself are the same.

【０００５】第１の方法はよく用いられる施工法である

Ａ周辺に別途穿設した孔Ｂに締付具を挿入して行ってい
た。この方法では構造上セパレータ同軸延長部で補強材
を締付けられないというデメリットがあった。[0005] The first method is a commonly used construction method, but does not perforate the mold face plate, but uses a hole A formed in the mold frame to form a plate-like separator at the end portion into two molds. Sandwich with a frame and clamp and fix with a fastener that penetrates them. In this case, the tightening of the reinforcing member is performed by inserting a fastener into a hole B separately formed around the hole A of the frame. This method has a disadvantage that the reinforcing member cannot be tightened at the separator coaxial extension due to the structure.

【０００６】第２の方法は、先ず型枠面板に孔Ｃを開

ンクリート固化後に余分な凹凸を生じ、仕上げ面の平滑
性を損ない、鋼製型枠自体の寿命（繰り返し使用可能回
数）を減ずるという問題点があった。In a second method, first, a hole C is formed in the mold face plate, a rod-shaped separator tip is inserted into the holes C, C of the double-sided plate, and a rod-shaped fastening member is inserted into a screw at the separator tip from the outside of the face plate. And tightening the reinforcing material. In this case, there is an advantage that the reinforcing material can be tightened by the coaxial extension of the separator. However, since a hole is formed in the face plate itself, extra irregularities are generated after solidification of the concrete, the smoothness of the finished surface is impaired, and the life of the steel formwork itself (the number of times it can be used repeatedly) is reduced.

り、作業が極めて困難であった。[0007] In addition, the conventional fasteners for steel formwork require additional fasteners (fasteners) for the reinforcement, so that it is not easy to secure them to these reinforcements. In particular, in dangerous places such as high places with poor scaffolding or in narrow places, using a separate fastener to secure the reinforcing material to the steel formwork requires a U-shaped locking tool and a straight rod Three types of parts, a fastener and a fastening washer, are required, and it is extremely difficult to work with accurate positioning of these parts, which is extremely difficult.

結果本発明に到達した。The inventor of the present invention has found that this problem can be solved all at once by adding a reinforcing member tightening portion to a part of the conventional locking device and integrating it. Reached.

上主として作業性の見地でβの範囲が決定される。In FIG. 1, the reinforcing member tightening portion 15 is threaded on the upper portion (a hot press process is also possible), and has a columnar shape. At its root, the horizontal projecting portion 20 and the extended linear portion are formed at angles β and γ, respectively. Connects to 11. At the rising angle α (80 ° ≦ α ≦ 130 °) from the extended straight portion 11, (γ and δ are almost 90).
゜) The narrow mouth U-shaped locking portion 5 stands up continuously.
The narrow mouth U-shaped locking portion 5 is a U-shaped surface 5A including the center line of the central portion.
The rising angle α is the angle formed by the plane 6 and the extended linear portion 11 in a plane including the center line of the reinforcing member fastening portion 15 orthogonal to the plane 6. is there.
Also, the angle β formed between the reinforcing material fastening portion 15 and the extension straight portion 11
Is desirably 85 ° ≦ β ≦ 110 °. The reason is that when β is less than 85 °, when the narrow-mouth U-shaped locking portion 5 is fully beaten, an extra inclination remains in the reinforcing member tightening portion 15, and conversely β
Exceeds 110 °, unless the α is reduced or the depth of the U-shaped portion of the narrow U-shaped locking portion 5 is increased, an extra inclination remains in the reinforcing member fastening portion 15 and is not practical. is there. The range of β is determined mainly from the viewpoint of workability.

C are substantially parallel to each other, and the gap 5D is slightly smaller than the sum of the thickness of the pair of frames 40, 40 and the separator end 50A. Therefore, three plates (the frame 40, the separator end 50A, In a state where the frame 40) is inserted (a pinching state), the frame 40 is expanded outward by elastic deformation, and
One plate (hereinafter referred to as a heavy plate) is pressed in the thickness direction, and the nut 27 and the spring washer 28 are pressed.
In combination with the tensile stress of the reinforcing material locking portion 15, the three members of the formwork (frame), the separator, and the reinforcing material can be firmly fixed without gaps (see FIGS. 1 and 2).

【００２０】この固着に至るプロセスは次の通りであ

で叩き込む事によってなされる。In FIG. 2, if 60A and 60B are a back face plate and a front face plate of a concrete wall, respectively, first, an end 50A of a separator 50 is sandwiched between frames 40 and 40 of a pair of face plates 60A and 60B, and respective holes are formed. 40B, 50B,
40B (hereinafter referred to as a heavy hole), and the horizontal projection 20 of the locking device of the present invention is inserted into the heavy hole. Usually, this insertion is performed by hitting with a hammer in the arrow X direction (horizontal projection axis direction) in FIG.

I hit it. That is, the reinforcing member tightening portion 15 is rotated about the horizontal projection 20 in the direction of arrow Z to be substantially horizontal or perpendicular to the predetermined portion of the concrete wall surface.

照）。At this time, the separator 50 simultaneously passes through the concrete 100 (however, fresh concrete will be injected later and still has a cavity at this time) and is connected to the joint of the front face plate 60B which is the opposite face (between the front face plates). The joints are the same as between the above-mentioned rear face plates), each concrete formwork is fixed in an I-shape, and a crossed reinforcing material is firmly fastened and fixed to the outside outside and the outside outside the concrete wall. By repeating this operation, a strong assembly form having a huge wall area can be easily formed. The reinforcing material may be in one direction without crossing according to the wall thickness and the wall area, or may be one piece instead of one pair (see FIG. 5).
