Description

  The present invention relates to a bar arrangement jig useful for bundling of horizontal bars or bundling of hoops.

  Conventionally, when placing a horizontal bar in the vertical bar, it has been necessary to bind the vertical bar and the horizontal bar with a wire (wire) while the worker holds the vertical bar and the horizontal bar. Also, when hoop muscles are arranged in the main muscle, the main muscle and the hoop muscle have to be tied together with a wire number while the operator holds the main muscle and the hoop muscle. As described above, when the horizontal bars are arranged in the vertical bars, or when the hoops are arranged in the main bars, it may be necessary to have a worker who only needs to hold the reinforcing bars (the horizontal bars or the hoop bars). there were.

  In order to facilitate the work of binding the horizontal muscle to the vertical muscle and the work of binding the hoop muscle to the main muscle, and to eliminate the situation where a number of workers are required only for gripping the horizontal or hoop muscle, A bar arrangement jig as shown is proposed.

  There has been proposed a concrete placement reinforcing bar in which arms for holding horizontal bars are fixed at predetermined intervals. The concrete placing reinforcing bar can hold the reinforcing bar on the arm in a state where it is suspended from the existing horizontal reinforcing bar. Therefore, if this concrete placement reinforcing bar is used, even if the horizontal bar is arranged in the vertical bar, the operator does not need to hold the vertical bar and the horizontal bar. In this concrete placement reinforcing bar, the arm has a saddle shape, and is fixed to the concrete placement reinforcing bar (see, for example, Patent Document 1).

  However, the concrete placement reinforcing bar described in Patent Document 1 is suspended by the existing horizontal bars and then held separately. After that, the concrete horizontal bars are restrained by the held horizontal bars. Can only be rotated together. Therefore, even if a plurality of straight transverse lines can be held, a plurality of hoop lines connecting one end and the other end cannot be held.

  On the other hand, an auxiliary bar has been proposed in which a stopper for holding a horizontal stripe is attached to be rotatable at predetermined intervals. The auxiliary bar can hold the horizontal bar in a state where it is suspended from the existing horizontal bar, in the same manner as the concrete placing reinforcing bar described above. Therefore, when this auxiliary bar is used, it is not necessary for an operator to hold the vertical and horizontal muscles even when the horizontal muscles are arranged in the vertical muscles, and the hoop muscles are arranged in the main muscles. However, since the stopper rotates, the auxiliary bar can newly hold the hoop muscle, and the operator does not need to grasp the main muscle and the hoop muscle (for example, see Patent Document 2).

JP 2001-115600 A JP-A-8-218637

  However, the auxiliary bar described in Patent Document 2 is a long member to which a stopper that holds the horizontal stripe is rotatably attached at every predetermined interval, and is inconvenient to carry.

  The present invention has been made in view of the above, and in the case where the horizontal muscle is arranged in the vertical muscle, or in the case where the hoop muscle is arranged in the main muscle, the worker can An object of the present invention is to provide a bar arrangement jig that does not need to hold a main bar and a hoop bar and is easy to carry.

In this state, the horizontal stripes or the hoop stripes can be held at predetermined intervals. The existing structures are, for example, already stretched horizontal bars, already stretched steel beams, already laid upper floors, or hoop bars already bound to the main bars.

  The bar arrangement jig 1 includes a main rope 2, a hanging tool 3, and a hook 4. The main rope 2 can be hung from an existing structure, and constitutes a reference body that serves as a bar arrangement reference for reinforcing bars (horizontal bars or hoop bars) when the main rope 2 is hung from an existing structure. The main rope 2 can be bent so that each of the plurality of hooks 4 can be moved out of the vertically lower area of the hook (hook 4) when it is suspended from an existing structure (hook 4). Specifically, it is constituted by a belt-like member made of fiber called a belt sling having flexibility that can be bent at an arbitrary position.

  As shown in FIGS. 1 and 2, the main rope 2 has a flat cross section and has two surfaces, a front surface and a back surface. As shown in FIG. 5, one end of the main rope 2 is folded back and sewn to itself (the main rope 2), and this portion constitutes a suspended portion 2a that is annular. The suspended portion 2a may be configured by folding one end of the main rope 2 and weaving it into the main rope (main rope).

  As shown in FIGS. 1, 2, and 5, a hanging tool 3 is attached to the annular hanging portion 2 a. The hanging tool 3 is used to suspend the main rope 2 from an existing structure, and is configured by combining a turnbuckle (adjusting means) 31 and a shackle 32. The turnbuckle 31 is a metal fitting that can be adjusted in length. A frame 31a is formed with a left-hand thread at one end and a right-hand thread at the other end, a hook-shaped hook bolt 31b at the end, and an annular end. Ring bolt 31c. The shackle 32 is a hook that cannot be adjusted in length, and includes a U-shaped crown 32a and a bolt 32b that passes through one end of the crown 32a and is screwed into the other end of the crown 32a.

The plurality of patches 21 are stitched so that the other surface of the main rope 2 (hereinafter, the other surface is referred to as the back surface) has a space between the reinforcing bars when the plurality of reinforcing bars are held. The plurality of patches 21 are stitched so as to be the second interval (for example, 150 mm interval). As shown in FIGS. 3 and 4, the patch 21 is for attaching the hook 4 to the main rope 2, and is constituted by a strip member made of a flexible fiber thinner than the main rope 2. The patch 21 has a flat cross section, and an upper portion and a lower portion are sewn to the main rope 2 so as to have a slack for the hook 4 to be inserted between the main rope 2 and the patch 21. For this reason, an insertion portion 22 through which the hook 4 is inserted is formed between the main rope 2 and the patch 21 and between the upper portion and the lower portion of the patch 21.

  Of the front and back surfaces of the main rope 2, the patch 21 is sewn at an interval (first interval or second interval) that matches the interval between the reinforcing bars (horizontal bars or hoop bars) and the reinforcing bars. The hook 4 is attached to the surface. That is, when the bar arrangement interval is the first interval (for example, 100 mm interval), the hook 4 is attached to the surface of the main rope 2, and the bar arrangement interval is the second interval (for example, 150 mm interval). In this case, the hook 4 is attached to the back surface of the main rope 2.

FIG. 7 is an explanatory diagram showing a state in which the bar arrangement jig according to the first embodiment of the present invention is suspended from an already laid upper floor. The bar arrangement work shown in FIG. 7 is effective when an upper floor F on which the anchor can be driven is laid on the lower surface, and the suspension 3 is combined with the turnbuckle 31 and the shackle 32 described above. Is used.

  In the example shown in FIG. 7, an anchor is driven into the lower surface of an existing upper floor F, and an eyebolt B is screwed into this anchor. The bar arrangement work is performed by suspending the bar arrangement jig 1 on the eyebolt B. In the example shown in FIG. 7, three bar arrangement jigs 1 are used, and adjacent bar arrangement jigs 1 are paired to hold the horizontal bar Y between them. In the tool 1, the horizontal stripes Y overlap. Then, by adjusting the suspension 3 of the bar arrangement jig 1, that is, the turnbuckle 31, the horizontal bar Y arranged on the left side and the horizontal bar Y arranged on the right side overlap without intersecting. Adjusted to

  Then, the horizontal bars Y are held in order from the upper stage to the lower stage between the hooks 4 and hooks 4 of the adjacent bar arrangement jigs 1, and the horizontal bars Y are bound to the existing vertical bars T. Thereafter, the turnbuckle 31 is loosened to widen the space between the uppermost hook 4 and the eyebolt B, and the reinforcing bar 1 is removed from the eyebolt B. Then, the eyebolt B is removed from the lower surface of the existing upper floor F to finish the bar arrangement work.

  Next, based on FIG.8 and FIG.9, the hoop reinforcement arrangement | positioning operation | work using the jig | tool for reinforcement arrangement concerning Embodiment 1 of this invention is demonstrated. FIG. 8 is a plan view showing the arrangement of the bar arrangement jig according to the first embodiment of the present invention in the hoop reinforcement arrangement, and FIG. 9-1 is a side view showing the arrangement of the hoop reinforcement. 9-2 is a side view showing the work of removing the bar arrangement jig. The bar arrangement work shown in FIG. 8 and FIG. 9 is effective when the hoop bar H is disposed on the existing main bar S, and a combination of the above-described turnbuckle 31 and shackle 32 is applied to the suspension 3. I am using it.

  In the bar arrangement work shown in FIGS. 8 and 9, the hoop muscle H serving as the bar arrangement reference is bound to the existing main reinforcement S. Then, the bar placement work is performed by suspending the bar placement jig 1 so that the hook 4 faces the inside of the hoop bar H. In the example shown in FIG. 8 and FIG. 9, the bar arrangement work is performed using two bar arrangement jigs 1 on two opposite sides. At this time, each of the plurality of hooks 4 moves outside the vertical lower region of the hook (hook 4) located directly above itself (hook 4), so that the hoop muscles H are held in order from the upper stage to the lower stage. And the hoop muscle H hold | maintained at each hook 4 is tied to the existing main reinforcement S by an operator (refer FIG. 9-1). Thereafter, the turnbuckle 31 is loosened to widen the distance between the hoop muscle H based on the bar arrangement and the uppermost hook 4, and the jig 1 for bar arrangement is removed from the hoop bar H based on the bar arrangement. The work is finished (see FIG. 9-2). In addition, by removing the bolt 32b from the shackle 32 without loosening the turnbuckle 31, the main rope 2 is removed from the shackle 32, and the turnbuckle 31 is removed from the hoop muscle H based on the bar arrangement reference to complete the bar arrangement work. You may do it.

  The above-described bar arrangement jig 1 according to the first embodiment of the present invention is provided with a main rope 2 suspended from an existing structure and a plurality of main ropes 2, and the main rope 2 is suspended from the existing structure. Since the hook 4 that holds the reinforcing bars (lateral bars Y) in the direction intersecting with the main rope 2 is provided when the lower bars are lowered, the vertical bars T can be obtained without the operator holding the vertical bars T and the horizontal bars Y. The transverse muscles Y can be bound together. In addition, the bar arrangement jig 1 according to the first embodiment can be moved out of the vertically lower area of each of the plurality of hooks 4 in a state where it is suspended from an existing structure. Since the reference body is constituted by the main rope 2 made of flexible fiber, the hoop muscle H newly held by the main rope 2 being bent is held by the hook 4 after avoiding the hook 4. Therefore, the operator can bind the hoop muscle H to the main muscle S without holding the main muscle S and the hoop muscle H. Moreover, by folding the bar arrangement jig 1 (main rope 2) according to the first embodiment at an arbitrary position, the bar arrangement jig 1 can be easily carried.

  Moreover, the suspension position of the main rope 2 can be adjusted by using the turnbuckle 31 for the hanging tool 3 of the reinforcing bar 1. Further, by loosening the turnbuckle 31, the distance between the existing structure and the uppermost hook 4 can be widened, and the bar arrangement jig 1 can be removed after the horizontal bars Y or the hoop bars H are bound.

  Further, the bar arrangement jig 1 sews the patch 21 so as to have the first interval on the surface, and sews the patch 21 so as to have the second interval on the back surface, and selects one of the front surface and the back surface. Since the hook 4 is attached, when the surface is selected and the hook 4 is attached, the horizontal stripe Y or the hoop reinforcement H can be arranged at the first interval, and the rear face is selected and the hook is attached. When 4 is attached, the horizontal stripe Y or the hoop reinforcement H can be arranged at the second interval.

The carabiner 81 is an O-shaped annular connecting means that can be partially opened. The clamp 82 can be opened and closed by connecting a pair of semi-cylindrical metal fittings 821 and 822 with a hinge 823, and a butterfly bolt 824 inserted through one semi-cylindrical metal fitting 821 is connected to the other. By screwing into a screw hole formed in the semi-cylindrical metal fitting 822, the metal fittings 821 and 822 can be kept closed. In addition, by attaching an internal tooth washer 825 having teeth on the inside of the butterfly bolt 824 through which one of the metal fittings 821 is inserted, the butterfly bolt 824 is not dropped from the one metal fitting 821.

  On the other hand, the bar arrangement jig 6 can be connected to the connection portion 7b by connection means (not shown) such as a carabiner or a shackle. By doing so, it is possible to arrange the necessary reinforcing bars at once.

  In addition, on one surface of the main rope 7, as in the case of the bar arrangement jig according to the first embodiment, when a plurality of reinforcing bars are held, the interval between the reinforcing bars is a predetermined interval (for example, an interval of 100 mm). ), A plurality of patches 71 are stitched together. As shown in FIGS. 12 and 13, the patch 71 is for attaching the hook 9 to the main rope 7 and has a color different from that of the main rope 7 (for example, blue when the main rope 7 is green). The belt is made of a flexible fiber-like member thinner than the main rope 7. Similarly to the bar arrangement jig according to the first embodiment, the patch 71 has a flat cross section and has a slack for allowing the hook 9 to be inserted between the main rope 7 and the patch 71. And the lower part are sewn to the main rope 7. Here, the color of the suture thread that sews the upper part and the lower part is different from the main rope 7 and the patch 71 (for example, orange), and at least the lower part is sewn so as to be double vertically.

  The patch 71 sewn to the main rope 7 is numbered. The numbers are attached so as to be raised one by one from the upper side to the lower side when the bar arrangement jig 6 is suspended, so that it can be used as a guide when the hook 9 holds the reinforcing bar. It has become.

  As described above, the main rope 7 sewed with the patch 71 is between the main rope 7 and the patch 71 and between the upper and lower portions of the patch 71 in the same manner as the bar arrangement jig according to the first embodiment. An insertion portion 72 through which the hook 9 is inserted is formed therebetween. The hook 9 is attached to the main rope 7 by inserting the hook 9 through the insertion portion 72.

  Similarly to the bar arrangement jig according to the first embodiment, the hook 9 is a reinforcing bar (horizontal bar or hoop bar) in a direction crossing the main rope 7 when the main rope 7 is suspended from an existing structure. Each of the hooks 9 is configured so that the size of the hook 9 is not more than one half of the reinforcing bar arrangement interval. The hook 9 has a bowl-like shape when viewed from the side, and is configured by bending a round bar-shaped steel material. The hook includes a shaft portion 91, a pair of leg portions 92, and a pair of hook portions 93. The shaft portion 91 is a portion that is inserted into an insertion portion 72 formed between the main rope 7 and the patch 71 described above, and is formed to be at least wider than the patch 71. The pair of leg portions 92 extend from one end and the other end of the shaft portion 91 so as to incline toward the center, and the tips thereof are formed to be wider than the thickness of the patch described above. is there. Therefore, although the tips of the leg portions 92 do not intersect, the shape of the isosceles triangle is exhibited together with the shaft portion 91 described above. The pair of hook portions 93 are extended from the leg portion 92 to the near side so as to have a predetermined diameter while maintaining a predetermined interval, and then folded back obliquely upward by approximately 135 degrees, so that the opening angle α is approximately 45 degrees. It is formed to be a degree. The hook portion 93 preferably has a small diameter and a sharp opening angle α within a range in which the reinforcing bars (horizontal bars and hoop bars) can be held, but the turning angle is approximately 135 degrees. If the reinforcing bars (horizontal bars, hoop bars) are not easily caught between the hook 9 and the main rope 7, they are folded back approximately 180 degrees and the opening angle is set to 0 degrees. Also good.

  The hook 9 configured as described above is inserted through the insertion portion 72 in the order of the hook portion 93, the leg portion 92, and the shaft portion 91, whereby the shaft portion 91 is inserted into the insertion portion 72 and the hook 9 is rotated around the main rope 7. Mounted movably.

  The bar arrangement jig 1 according to Embodiment 1 described above is configured by combining the turnbuckle 31 and the shackle 32 as the suspending tool 3. For this reason, the overall length of the hanging tool 3 must be long, and the interval between the existing reinforcing bar in which the reinforcing bar 1 is suspended and the reinforcing bar in the uppermost stage of the reinforcing bar 1 is desired. The interval may be exceeded. In this case, it is necessary to separately arrange the reinforcing bars regardless of the reinforcing bars.

  In contrast, the bar arrangement jig 6 according to the second embodiment is configured by combining a carabiner 81 and a clamp 82 as the hanging tool 8. For this reason, the overall length of the hanging tool 3 can be shortened, and the interval between the existing reinforcing bar and the reinforcing bar arranged on the uppermost stage of the reinforcing bar 6 is secured by suspending the reinforcing bar 6. Can do. Therefore, unlike the bar arrangement jig according to the first embodiment, it is not necessary to separately arrange reinforcing bars.

  In the bar arrangement jig 1 according to the first embodiment described above, when reinforcing bars are arranged on all the hooks 4, a large load acts on the hanging tool 3. For this reason, there is a large force between the hanger 3 (particularly the turnbuckle 31) suspended from the existing reinforcing bars and the reinforcing bars arranged at the uppermost stage of the reinforcing bar 1 (reinforcing bars). Will remain, making it difficult to remove the reinforcing bar jig 1.

  On the other hand, the bar arrangement jig 1 according to the second embodiment configures the hanging tool 8 by combining the carabiner 81 and the clamp 82, so that a large load acts on the clamp 82. Since a large load does not act on the butterfly bolt 824, the bar arrangement jig 6 is easier to remove than the bar arrangement jig according to the first embodiment.

  In addition, since the bar arrangement jig 6 according to the second embodiment is configured with the connecting portion 7b on the main rope 7, the bar arrangement jig 6 can be connected to the main rope 7 by connecting means such as a carabiner or a shackle as required.
