[Previous technology]

 When building concrete walls for various types of buildings or structures at a construction / construction site, in the past, first, foundation work was performed, and one end of the reinforcing bar was fixed to the foundation, and the required number of A single row or a plurality of rows are arranged in the direction, and further, the reinforcing bars are attached and fixed in the horizontal direction to a number of rows or a plurality of rows and to the longitudinal reinforcing bars to the extent that the height of the concrete wall is commensurate. As for the metal fittings used for mounting and fixing, no special locking metal fittings are found.In almost all construction / construction sites, a convenient wire is cut into a certain length to cross the vertical and horizontal reinforcing bars. The part was locked and fixed. There was a method in which the reinforcing bars embedded in the concrete wall were entangled with each other and locked and fixed.

[0003]

[Problems to be solved by the device]

 Prior to the concrete wall formation at the building or construction site, the rebars embedded in the concrete wall were fastened to each other with wires cut to a certain length. Therefore, first of all, it took a lot of time and labor to cut the wire, and since the cutting was also by visual measurement, the wire was long, short, or had different lengths. It was a waste of money. Also, when the reinforcing bars are locked and fixed with this wire, the crosswise portions of the vertical and horizontal reinforcing bars are locked and fixed one by one. It is wrapped around, locked and fixed. For this reason, it takes a considerable amount of time and labor to lock and fix one crossing portion, and as a whole, it takes a lot of time and labor to secure and fix the reinforcing bars to each other, resulting in work efficiency. Was bad, and sometimes the rebars were displaced or tilted. Furthermore, the arrangement of the reinforcing bars embedded in the concrete wall complicates the arrangement of the reinforcing bars even when the vertical and horizontal reinforcing bars are locked and fixed by themselves. There were some drawbacks and inconveniences, such as the fact that the horizontal reinforcing bars were not firmly fixed.

[0004]

[Means for Solving the Problems]

 In order to eliminate such conventional drawbacks and inconveniences, in a tubular body formed of a single plate, one side wall of the tubular body is formed with a slight opening, and both ends of the opening portion are formed into a young body. The two tubular bodies that are formed by bending the tubular body outwardly are oriented so that one side wall of the tubular body having the opening is directed in the opposite direction, and one tubular body is oriented in the longitudinal direction. The other I-body is achieved by using a reinforcing bar locking fixture, which is formed by joining and fixing the central back portions of the tubular body in the lateral direction. Thus, the present invention seeks to provide a reinforcing bar locking fixture, which has never been seen before.

[0005]

[Work]

 The reinforcing bar locking fixture according to the present invention is formed in a tubular body having a slight opening, and the tubular bodies are fixed back-to-back, one body vertically and one body horizontally. It is formed by. Therefore, at the intersections of the vertical and horizontal rebars that form the concrete wall, the vertical rebars are fitted into the longitudinally oriented tubular body through its openings, and the horizontal rebars are Insert it into the tubular body facing in the lateral direction from its mouth. By doing so, the reinforcing bars embedded in the concrete wall are fixed at the vertical and horizontal intersections, the reinforcing bars do not shift or tilt, and no wire is used. It has the action and effect of good efficiency.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a reinforcing bar locking fixture according to the present invention, and FIG. 2 is a usage state diagram showing a usage state of the reinforcing bar locking fixture. (1) is a rebar locking fixture main body. This rebar locking fixture body (1) consists of two identical tubular bodies each having a slight opening, one body oriented in the longitudinal direction and one body oriented in the lateral direction, fixed back to back. It has been formed. However, the tubular body does not always have to be the same body and may be formed of different sizes. It is possible to form various kinds of reinforcing bar locking and fixing metal fitting bodies (1) according to the thickness of the reinforcing bar. The material of the main body (1) of the reinforcing bar locking and fixing metal can be made of iron material, steel material, synthetic resin material or the like having elasticity to some extent. The two tubular bodies are fixed back-to-back with almost no movement, which allows the reinforcing bars to shift when the reinforcing bar locking fixture body (1) is used at the crossing of the reinforcing bars. , It is what prevents you from leaning. (2) is a tubular body forming the reinforcing bar locking fixture main body (1). The pipe hull (2) is formed to some extent by a convenient material such as an elastic iron material or steel material or a synthetic resin material. In this embodiment, iron material is used. The tubular body (2) is formed in a cylindrical shape, and one end of a side wall of the cylindrical shape is opened. This tubular body (2) does not necessarily have to be cylindrical. It is also possible to form it according to the shape of the reinforcing bar. The tubular bodies (2) are not all the same size but can be formed in various sizes, and the cylindrical inner diameter can be formed in various sizes. it can. In this embodiment, it is formed in a cylindrical shape. (3) is an opening provided in one side wall of the pipe hull (2). This opening part (3) is formed by forming the tubular body (2) without joining both ends of the single plate when forming the tubular body (2) with a single plate material. . The opening (3) is formed on one side wall of the tubular body (2) by the length of the side wall. A reinforcing bar is inserted into the tubular body (2) through the opening (3). (4) is the end of the tubular body (2) forming the opening (3). This end (4) is a single plate and is an end of the single plate when forming the tubular body (2), and is both ends forming the opening (3). The end (4) is formed by bending a part of the end (4) outward of the pipe slab (2) after forming the opening (3). By bending the end (4) outward of the tubular body (2), a slight stopper function is achieved. The two bodies of the tubular body (2) thus formed are respectively provided with openings (3) formed on one side wall of the tubular body (2) in opposite directions, that is, for example, one tubular body. If the opening part (3) of (2) is directed to the right side, the opening part (3) of the other tubular body (2) is directed to the left side, and so on. The body is oriented vertically and the other tubular bodies (2) are oriented transversely, and fixed by jointing at the center of the back of each tubular body (2). (5) is a joining member. The joining member (5) can be integrally formed without using it. In this embodiment, it is supposed that the joint member (5) is used for fixing. The joining member (5) may be a bit or a nail as long as it is a member capable of fixing the two tubular bodies (2). By this joining member (5), the two tubular bodies (2) are fixed in the vertical and horizontal directions, respectively, to form one rebar-retaining metal fitting body (1). In order to use the reinforcing bar locking metal fitting (1) formed in this way, when forming a concrete wall, the reinforcing bar embedded in the concrete wall is assembled to reinforce the concrete wall. Is normal. Usually, a plurality of (reinforcing) reinforcing bars are provided vertically and horizontally. The reinforcing bar locking fixture (1) is used at the crossing part of the reinforcing bar, and one body is used at one crossing part of the vertical and horizontal reinforcing bars. To use it, insert the longitudinal reinforcing bars into the vertical tubular body (2) through the opening (3) in the vertical tubular body (2) of the reinforcing bar locking fixture (1), and similarly, The rebar in the direction is fitted into the tubular body (2) through the opening (3) of the lateral tubular body (2). By doing so, the reinforcing bars for concrete wall reinforcement are fixed vertically and horizontally at the vertical and horizontal intersections. This will prevent the rebar from being distorted or tilted. Further, the reinforcing bar can be simply fitted into the tubular body (2) through the opening (3) of the tubular body (2). Incidentally, (6) and (6 ') are reinforcing bars.
