Description

The present invention relates to a reinforcing bar positioning jig having a design for calibrating the position of the reinforcing bar and its use and a jig shelf using the same.

In the design of the wire mesh structure, it is usually manufactured using a jig shelf, which saves time for manual work. FIG. 1 is a conceptual diagram of a conventional jig shelf. The jig shelf 10 has a structure having a frame 12, and a plurality of poles 14 are straddled on two sides of the frame 12, and each pole 14 has a stereotactic seat 16 installed at intervals. The stereotaxic seat 16 has slotters 16a and 16b in different directions (see FIG. 2). Reinforcing bars 18a and reinforcing bars 18b in different directions are placed on each other and superposed to form a mesh, and are welded and formed.

However, in the conventional technique described above, the slotter of the stereotaxic seat becomes wider as it approaches the upper opening (see FIG. 3), and the position of the reinforcing bar 18a placed on the upper layer shifts. 2 and 3 are conceptual diagrams of placing reinforcing bars by a conventional jig shelf. Some of the upper rebars are well positioned in the middle position of the stereotaxic seat, except that the positions of some of the upper rebars are away from the middle position of the stereotaxic seat. For example, the reinforcing bar 18a-1 and the reinforcing bar 18a-2 are not located in the middle position of the stereotaxic seat, the former position is slightly shifted to the left, and the latter is shifted slightly to the right (see FIG. 3). In this case, an error from the original design occurs in the wire mesh structure after welding, and the position of each reinforcing bar must be adjusted one by one by human power, and a lot of time is spent. It also affects the progress of construction. In view of these, there is a need to improve the current jig shelf and the stereotaxic seat used there.

Therefore, the present inventor considered that the above-described drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems with a rational design.

The present invention has been made to solve the above-described problems of the prior art. That is, an object of the present invention is to provide a reinforcing bar positioning jig and a jig shelf using the same.

In order to solve the above-described problems and achieve the object, the reinforcing bar positioning jig of the present invention includes a first side plate having a first upright surface installed in a first direction,
A second side plate having a second upright surface installed in a direction crossing the first direction, and connected to the first side plate and the second side plate, and further to the first side plate and the second side plate Each of the openings is formed, and the opening includes a top plate portion positioned at a bottom portion of the first side plate and the second side plate.

According to the present invention, the welding efficiency of the upper and lower reinforcing bars is increased.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment described below does not limit the contents of the present invention described in the claims of the utility model registration. In addition, all the configurations described below are not necessarily essential requirements of the present invention.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 4A, the reinforcing bar positioning jig 100 includes a first side plate 110, a second side plate 120, and a top plate portion 130. The first side plate 110 has a first upright surface 112 installed toward the first direction a. The second side plate 120 has a second upright surface 122 installed in a direction crossing the first direction a. In another embodiment, the second upright surface 122 is installed toward the second direction b perpendicular to the first direction a. The top plate 130 has a notch 132 formed at one end away from the first side plate 110 and the second side plate 120 by being contracted toward the first side plate 110 and the second side plate 120. The reinforcing bar positioning jig 100 further includes a rotation connecting member 150 fixed to the top plate portion 130. The rotation connecting member 150 interlocks the first side plate 110 and the second side plate 120 to rotate in parallel with the plane of the top plate portion 130.

Further, the first side plate 110 and the second side plate 120 are further formed with an opening 116 and an opening 126, respectively. The opening 116 and the opening 126 penetrate the first upright surface 112 and the second upright surface 126, respectively. The positions of the bottom 114 and the bottom 124 of the first side plate 110 and the second side plate 120 are wide, and the widths of the opening 116 and the opening 126 gradually converge toward the top plate 130. As shown in FIGS. 4A and 4B, the two inner side surfaces (1161, 1162) of the first side plate 110 and the two inner side surfaces (1261, 1262) of the second side plate 120 are formed from the bottom portion 114 and the bottom portion 124 to the top plate portion 130. The widths of the opening 116 and the opening 126 decrease as the distance from the bottom 114 and the bottom 124 of the first side plate 110 and the second side plate 120 gradually increases. The plate 130 has a slightly arc shape and is connected to the first side plate 110 and the second side plate 120 (see FIG. 4B). In addition, the outer shape of the top plate portion 130 has more space on one side away from the first side plate 110 and the second side plate 120 (that is, one side close to the notch portion 132) so as to suit the arc-shaped design. Therefore, the reinforcing bar positioning jig has a larger notch 132.

Next, the jig shelf 200 includes a frame 210, a plurality of poles 220, a plurality of lower positioning seats 230, and a plurality of reinforcing bar positioning jigs 100 (see FIG. 5). The frame 210 has a first side 211 and a second side 212. The pole 220 is connected to the first side 211 and the second side 212 and is distributed along the first side 211. The lower positioning seat 230 is installed on the pole 220, and a plurality of reinforcing bars are superimposed on the lower positioning seat 230. The lower positioning seats 230 of the poles 220 are installed at regular intervals, and the lower positioning seats 230 of adjacent poles 220 are spaced from each other.

As shown in FIG. 6, each lower positioning seat 230 has a first slotter 231 and a second slotter 232. The first slotter 231 is parallel to the first direction a, and the second slotter 232 is parallel to the second direction b. Each lower positioning seat 230 has the first layer rebar 310 placed in the first slotter 231, and the second layer rebar 320 placed in the second slotter 232. Are superimposed on each other to form a crossed installation. The rebar positioning jig 100 to be aligned is positioned above the pole 220 and is installed corresponding to the intersection of the first layer rebar 310 and the second layer rebar 320, and the notch 132 of the rebar positioning jig 100 is viewed from above. It is exposed at the crossing point of the rebar, avoiding the activity space from above to below the welding device (not shown).

Moreover, it has the reinforcing bar positioning jig 100 above the location where the first layer reinforcing bar 310 and the second layer reinforcing bar 320 intersect (see FIG. 7A). The first layer rebar 310 is located at the center position between the slotters, but the first layer rebar 310-1 and the first layer rebar 310-2 shift.

According to FIG. 7B, the reinforcing bar positioning jig 100 is rolled down, and the reinforcing bar located in the upper layer (in this embodiment, the first layer reinforcing bar) approaches the pole 220 according to the reinforcing bar positioning jig 100, and approaches the inner surface of the opening 116. The first layer rebar 310-1 that contacts and moves to a predetermined position (for example, the center position between the slotters) on the second layer rebar 320 as the opening 116 converges, The first layer rebar 310-2, which is guided to the inner side surface 1161 and moved to the center position between the slotters, is guided to the center position between the slotters by being guided according to the inner side surface 1162 of the opening 116. As a result, the shifted rebar is adjusted to the necessary position, and reworking of the wire mesh is required, thereby avoiding unnecessary time.

Furthermore, it has the reinforcing bar positioning jig 100 above the location where the first layer reinforcing bar 310 and the second layer reinforcing bar 320 intersect (see FIG. 8A). The difference from the above-described embodiment is that the first side plate 110 and the second side plate 120 of the reinforcing bar positioning jig 100 are rotated in different directions and are changed so as to be directed to the first layer reinforcing bar 310 from the opening 126 of the second side plate 120. It is a point to be done. According to FIG. 8B, the reinforcing bar positioning jig 100 is rolled down, and the first layer reinforcing bar 310 approaches the pole 220 according to the reinforcing bar positioning jig 100 and is fixed at the center position between the slotters.

In addition, according to FIG. 9, since the 1st layer reinforcing bar 310 is short, the reinforcing bar positioning jig 100-1 located in the position of an edge compared with the reinforcing bar positioning jig 100 is based on arrangement | positioning of the reinforcing bar positioning jig 100. Since the first side plate does not contact the first layer rebar 310, the effect of adjusting the rebar cannot be achieved. In this case, the reinforcing bar positioning jig 100-1 is rotated and modified so as to press the first layer reinforcing bar 310 by the other side of the second layer reinforcing bar 320 of the second side plate. Thereby, the position of the reinforcing bar can be adjusted at any position of the wire mesh.

Accordingly, the embodiments disclosed herein are for the purpose of explaining, not limiting the present invention, and the spirit and scope of the present invention are not limited by such embodiments. The present invention should be construed according to the claims, and all technologies within the equivalent scope should be construed as being included in the scope of the present invention.
