Description

  A concrete frame form made of concrete constructed on a glue (law) surface has a separator (hoop tie) interposed between opposing metal meshes, with a vertical gutter and a horizontal gutter fastened together, and the vertical gutter is placed in the separator. The present invention relates to a reinforcing bar fixture for a frame frame used when fixing the reinforcing bar to the separator.

  A separator-like groove-like engaging portion is provided on one end side of the main body piece having a through hole for a vertical wall of the separator in the intermediate portion, and between the vertical wall on the other end side of the main body piece. There is a structure in which an elastic holding piece that partially engages an engaged reinforcing bar is erected, and this conventional structure has a main piece piece that has a vertical hole penetrating through a through hole. In this example, the reinforcing bar fixture is combined with the vertical shaft of the separator, moved to the intersection of the vertical rod and horizontal rod (lowered or raised along the vertical rod), and then rotated around the vertical rod. Thus, a reed is fitted inside the engaging portion, and a reinforcing bar is engaged and fixed between the elastic holding piece and the vertical reed facing each other when it is fitted (for example, Patent Document 1).

JP 2005-61015 A

  In the conventional structure, the vertical rod must be in the shape of a straight bar because the vertical rod needs to penetrate (relatively) the through hole provided in the main body piece when assembled to the separator. There are restrictions on application, and after assembling to a downspout, it is necessary to rotate the downside about the downspout and to assemble it with a downside, so that the assembling operation is complicated.

  The present invention was devised for the purpose of providing a reinforcing bar fixture for a formwork for a glue frame that can reduce application restrictions and easily perform an assembling operation as compared with the conventional example.

  Reinforcing bar for the formwork for the frame, in which a separator composed of a vertical bar and a horizontal bar fixed to each other is interposed between opposing metal meshes, and the reinforcing bar arranged at the crossing part of the vertical bar and the horizontal bar is fixed to the separator. The fixing tool has a groove-shaped holding frame provided with a first and a second pair of holding pieces for elastically holding the recumbent fitting fitted therein, and the pair of holding pieces of the holding frame have the above-mentioned A notch for engaging the vertical hook when the horizontal hook is clamped by the holding piece is provided in an intermediate portion along the axis of the horizontal hook, and the vertical hook is provided at one end of the first holding piece in the axial direction. It is set as the structure which provided the holding piece which engages partially with the peripheral side of the said reinforcing bar interposed between.

  According to the present invention, a horizontal bar can be interposed between a pair of holding pieces, and at the same time, a vertical bar can be engaged with a notch provided in the holding piece. It is possible to provide a reinforcing bar fixing tool that can be easily assembled at the crossing portion between the horizontal bar and the horizontal bar and that can securely hold the reinforcing bar with the holding piece and the vertical hook.

  FIG. 1 shows an embodiment of a reinforcing bar fixing tool for a frame according to the present invention, FIG. 1 is a schematic front view showing a use state, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. FIG.

  According to the present invention, the rebar fixing tool A of the formwork for the glue frame is composed of the vertical bar 1a and the horizontal bar 1b constituting the separator 1 with the reinforcing bar 2 provided between the separators 1 and 1 of the formwork F of the glue frame C. It is used for fixing to the crossing part (fastening part), and the above-mentioned form frame F is fixed to each other by arranging a pair of said vertical rods 1a, 1a and horizontal rods 1b, 1b in a substantially cross-beam shape. The attached separator 1 is arranged between wire meshes 3 and 3 arranged opposite to each other, and these are coupled to each other.

  The reinforcing bar fixing tool A is formed by pressing a metal plate, and has a groove shape (U-shape) including a first and a second pair of sandwiching pieces 4 and 5 for interposing and sandwiching the horizontal bar 1b. ) And a holding piece 7 provided at one end of the first holding piece 4 of the holding frame 6 in the axial direction of the horizontal bar 1b.

  The holding frame 6 includes a notch 8 that engages the vertical rod 1a at an intermediate portion of the pair of holding pieces 4 and 5 in the longitudinal direction (the axial direction of the horizontal rod 1b when pinched). A locking ridge 9 that bulges in the direction of the first clamping piece 4 is provided at an appropriate position of the second clamping piece 5 so that the holding state of the horizontal rib 1b by both the clamping pieces 4 and 5 is securely held. It is.

  The holding piece 7 connected to one end of the first holding piece 4 of the holding frame 6 is bent substantially in a V shape at the free end side of the main body piece 7a holding the reinforcing bar 2 with the vertical rod 1a. Thus, a folded portion piece 7b is provided, and the leading end of the folded portion piece 7b is bifurcated to provide an engagement notch 7c.

  Thus, the ladle 1b faces the pair of sandwiching pieces 4 and 5 constituting the sandwiching frame 6 and the vertical fence 1a faces the notch 8 provided in the sandwiching pieces 4 and 5, respectively. When the fixing bracket A is disposed at the intersection of the vertical rod 1a and the horizontal rod 1b of the separator 1 constituting the frame form F and pressed in the direction of the separator 1, the horizontal rod 1b is sandwiched between the clamping pieces 4 and 5 While being fitted (relatively) against the elastic biasing of the pieces 4 and 5 and being sandwiched by the sandwiching pieces 4 and 5, the vertical rod 1 b is engaged (relatively) with the notch 8. Therefore, the fixing bracket A is assembled to the intersection of the vertical and horizontal ribs 1 a and 1 b of the separator 1, and in the assembled state, between the holding piece 7 of the fixing bracket A and the vertical rod 1 a of the separator 1. An engagement gap a of the reinforcing bar 2 is formed.

  When the peripheral side of the reinforcing bar 2 is engaged with the engagement gap a, the reinforcing bar 2 is sandwiched between the main body piece 7a of the holding piece 7 and the vertical rod 1a by elastic deformation of the holding piece 7. On the other hand, the tip of the folded-back piece 7b of the holding piece 7 is pressed against the rebar 2 circumferential side, the rebar 2 is partially held by the holding piece 7, and the reinforcing bar is inserted into the engagement notch 7c provided at the tip. The protrusions 2 ′ provided on the two circumferential sides engage with each other so that the reinforcing bar 2 is securely fixed at the crossing portion of the vertical rod 1 a and the horizontal rod 1 b of the separator 1.

The schematic front view which shows a use condition. The partially expanded view of FIG. FIG. 3 is a partially cutaway plan view of FIG. 2.
