BEST MODE FOR CARRYING OUT THE INVENTION A specific mode for carrying out the present invention will be described below with reference to the drawings. [First Embodiment of the Invention] First, in the first embodiment of the present invention, referring to FIGS. 1 and 2, for a first reinforcing bar holder having two fitting portions in upper and lower two stages, respectively. While explaining. Here, FIG. 1 is a perspective view showing the appearance of the first reinforcing bar holder. FIG. 2 is a diagram showing a state where the reinforcing bars are fitted in the first reinforcing bar holder.

In FIG. 1, the reinforcing bar holder 10 is formed by a working method such as pressing or molding a metal plate, and its height is about 50 to 500 mm according to the Building Standards Law. . The rebar holder 10 has a leg portion 18, a base portion 14, and two fitting portions 12 and 16. Leg 1
8 has legs 22 and 30 which are bifurcated, and end pieces 20 and 24 extending in mutually opposite directions are provided at the tips of the legs 22,
Similarly, the tip of the leg 30 has end pieces 26 and 28 extending in mutually opposite directions. This leg portion 18 is a holder 1 for the reinforcing bar.
It plays the role of preventing 0 from falling. Therefore, the leg portion 18 is not limited to this structure, and may have a structure in which the reinforcing bar holder 10 does not fall down like a plurality of leg portions 206 shown in FIG. 13, for example.

The base portion 14 is a portion extending upward from the leg portion 18 to the fitting portion 12. The base portion 14 is formed by bending it into a "]" shape when viewed from the side direction (or cross section), and a part of the base portion 14 together with the holding piece 48 is fitted into the fitting portion 16.
Is part of. The base portion 14 is not limited to the "]" shape, but may be formed by bending into an arbitrary shape such as a ")" shape or a ">" shape that can hold the reinforcing bar fitted in the fitting section 16. May be. The reason that the base portion 14 is formed by bending is that the reinforcing bars held by the fitting portion 12 and the fitting portion 16 are located at the same position in the vertical direction. Therefore, when it is not necessary to position the reinforcing bars at the same position in the vertical direction, the base portion 14 may be formed in any shape such as a straight line or a curved line.

The fitting portion 12 is on the upper portion of the base portion 14, two holding pieces 42 and 44 are formed in a "Y" shape, and two supporting pieces 40 and 40 are formed at the central portions of the holding pieces 42 and 44, respectively. Four
6 is formed in a "U" shape. Of these, the support piece 40 has a structure in which a part of the holding piece 42 is cut out and bent outward. This structure has a supporting piece 46 and a holding piece 4.
The same applies to 4. Further, the holding pieces 42, 44 and the support pieces 40, 46 have a structure in which the reinforcing bars fitted therein intersect at a right angle. The supporting pieces 40 and 46 and the holding pieces 42 and 44 are not limited to the above-described shapes, and the reinforcing bars may be fitted in such a shape as a “J”, “S”, “V” shape, etc. It may be formed in a shape that can be formed and can be held thereafter. Further, the structure is not limited to the structure in which the two reinforcing bars fitted in the holding pieces 42, 44 and the supporting pieces 40, 46 intersect at a right angle, but intersects at a predetermined angle (for example, a narrow angle of 30 degrees or 45 degrees). Structure,
It is also possible to form parallel structures. further,
Depending on the shape of the holding pieces 42, 44, two or more reinforcing bars can be fitted at the same time.
The same applies to 0, 46 and other holding and supporting pieces.

The fitting portion 16 is located on the upper portion of the leg portion 18 (or the lower portion of the base portion 14), and has a support piece 32 and three holding pieces 3.
4, 36, 48 and a part of the base portion 14. Support piece 32
Is an end piece extending from the lower end of a notch 38, which is a part of the base 14 cut away, and serves as a base for the reinforcing bars. Holding piece 34,
Reference numeral 36 is a part of the holding piece 4 which is cut away.
Like 2,44, it is formed in a "Y" shape. Also,
The holding piece 48 and a part of the base portion 14 are also formed in a “Y” shape. The holding pieces 34, 36 and the holding pieces 48 and a part of the base portion 14 hold the reinforcing bars by passing the reinforcing bars over both of them. Further, the support piece 3
2 and the holding pieces 34, 36, the holding piece 48, and a part of the base portion 14 have a structure in which the reinforcing bars fitted in each cross at a right angle. In this structure, the notches 38 and the holding pieces 34, 36 are partially cut out so that the reinforcing bars can be easily guided to the support pieces 32. Further, the holding pieces 34 and 36, and the holding pieces 48 and a part of the base portion 14 can be fitted so as to lower the reinforcing bar from above like the above-mentioned supporting pieces 40 and 46, and can be held thereafter. It may be formed in a shape. Further, the holding pieces 34, 36 and the holding pieces 48 and a part of the base portion 14 are not limited to the structure in which the reinforcing bars fitted in the respective holding pieces intersect at a right angle, but are formed in a structure intersecting at a predetermined angle. It is also possible.

FIG. 2 shows a state in which the reinforcing bars are fitted and held in the reinforcing bar holder 10 having such a structure. In FIG. 2, two reinforcing bars 50 and 52 can be fitted in the fitting portion 12, and another two reinforcing bars 54 and 56 can be fitted in the fitting portion 16. Here, in the actual reinforced concrete construction and the like, the rebars 50 to 56 having a thickness of about 6 to 16 mm are often used, and the fitting portions 12 and 16 are formed so that the rebars having this thickness can be exactly accommodated. In this way, one rebar holder 10 can simultaneously hold up to four rebars. Moreover, in the fitting portions 12 and 16, the two reinforcing bars intersect each other at a right angle in each of the fitting portions, so that the two reinforcing bars can intersect at a right angle without performing special work. In this way, it is possible to save the labor of binding the two reinforcing bars with the smoothed iron wire and the labor of crossing at right angles, so that the time required for the assembling work of the reinforcing bars can be significantly shortened. Moreover, the linearity of the reinforcing bar can be maintained by using the plurality of reinforcing bar holders 10 along the reinforcing bar. Further, the proper position of the reinforcing bar can be made robust, and at the same time, the disturbance generated after the conventional reinforcing bar construction can be eliminated (prevented). It should be noted that if ribs are appropriately arranged on each part (especially the flat plate part) of the reinforcing bar holder 10, it is possible to provide rigidity while preventing deformation. By this rib, it becomes possible to sufficiently oppose the load applied to the reinforcing bar holder 10 when concrete is driven in, and the reinforcing bar can be reliably held at the same position. Further, if the leg portion 18 is formed in a shape capable of holding a reinforcing bar such as the holding portions 42 and 44, the reinforcing bar holder 10
It is possible to attach to the rebar and to hold the rebar on it.

Next, the spirit level attached to the above-described rebar holder 10 will be described with reference to FIGS. 3 to 6. This level is also called “leveling”, and is an instrument that indicates the cover thickness (that is, the proper distance between the concrete surface and the reinforcing bar) and also indicates the concrete crown. Further, regarding the drawings, FIG. 3 is a view showing a configuration of a spirit level, FIG. 4 is a view showing a fitting portion and a spirit level, and FIG. 5 is a state in which a spirit level is attached to the fitting portion. It is a figure. FIG. 6 is a diagram showing a configuration of another attachment portion of the spirit level.

The spirit level is composed of an adjusting member 60 and a mounting member 70. The structure of the adjusting member 60 is shown in FIG.
FIG. 3A is a front view showing the structure of the mounting member 70.
It is shown in a three-sided view in (B). The adjusting member 60 includes a head 64 and a screw member 66. The head 64 is formed in a substantially hemispherical shape, and the pin 62 is provided at the apex thereof. Threads are provided on the screw member 66. On the other hand, the mounting member 70 is composed of a main body 74 and a clip 76. The main body 74 is the screw member 6 described above.
Screw 6 from above (arrow D2 direction shown),
It is provided with a female screw 72 for adjusting the cover thickness.
The clip 76 is composed of an end piece for sandwiching the main body 74 in the reinforcing bar holder 10, and the tip of the end piece is formed so as to spread so as to be easily sandwiched. Further, a stopper 78 that prevents the clip 76 from coming off after being attached to the reinforcing bar holder 10 is provided on the end piece that constitutes the clip 76.

The level bar having the above structure is used as the rebar holder 1.
An example of attachment to 0 will be described with reference to FIGS. 4 and 5. As shown in FIG. 4, the spirit level in which the adjusting member 60 is screwed into the mounting member 70 is lowered from above the holding piece 42 of the reinforcing bar holder 10 (direction of arrow D4 shown in the drawing),
All that is required is to clip the clip 76 of the electronic level to the holding piece 42. FIG. 5 shows a state in which the spirit level is thus attached to the reinforcing bar holder 10. Therefore, since the spirit level can be attached to the reinforcing bar holder 10 with one touch, the workability is very good. Further, since the end piece of the clip 76 is not so thick, the reinforcing bar can be fitted even after the spirit level is attached to the reinforcing bar holder 10. With the level attached in this way, the cover thickness or the top of the concrete can be easily identified, and the concrete can be easily driven. On the other hand, it is provided with an adjusting part 60 capable of adjusting the covering thickness, and is provided with the reinforcing bar holder 10 and other members (for example, reinforcing bars, beams,
Since it has a mounting portion 70 for mounting it on a mold, wire, etc., it can be used as a single body. Further, the cover thickness can be adjusted only by attaching the cover portion 70 to another member. When the holding piece 42 is provided with the hole 43, the stopper 76 is used to insert the hole 4 into the hole 4 when pinching.
3 and engage. Therefore, it becomes difficult for the level to come off after the level is attached to the reinforcing bar holder 10.

As described above, the spirit level includes two types of members each having a simple shape (that is, the adjusting member 60).
And the mounting member 70) are combined, the size of the entire spirit level can be reduced, and the manufacturing cost thereof can be kept low. Here, the spirit level is a holder 10 for the reinforcing bar.
However, it may be formed integrally with the reinforcing bar holder 10. In particular, when it is made of metal, plastic, or the like, the leveling member 70 and the reinforcing bar holder 10 can be integrated, and even when the adjusting member 60 is only the pin 62, Can be united.
It should be noted that at least the pin 62 is sufficient as the level, and other members and parts such as the head 64 and the screw member 66 can be arbitrarily added.

The clip 76 has a structure for attaching to the flat plate portion of the reinforcing bar holder 10. Instead of the structure (structure or member) of the clip 76, a clip, a pin, a thumbtack, or the like is used. It may be formed of a member having a sharp tip, may be formed of a magnetic material such as a magnet, or may be formed of a viscous material such as clay. Further, one of the portion corresponding to the clip 76 and the mounting portion of the reinforcing bar holder 10 may be formed in a concave shape and the other in a convex shape, and both may be fitted together. That is, the clip 74
The part corresponding to (3) may have a structure for attaching the level to other members. Even with these structures, workability is good, the size of the entire spirit level can be reduced, and the manufacturing cost thereof can be kept low.

Instead of the leveling member 70 as described above, a mounting portion 80 as shown in FIG. 6 may be used. FIG. 6A is a perspective view of the mounting portion 80, and FIG.
It shows in (B). Here, the mounting part 80 is different from the mounting member 70 in that instead of the female screw 72, a notch part 82 which is formed by radially cutting out several (four in the figure) from the hole 84 of the main body 86 is provided. Is. Since the notch 82 is formed so as to float (spirally) from one end to the other end, the screw member 66 of the adjusting member 60 can be screwed. Further, the notch 82 eliminates the need for the female screw 72, so that the manufacturing cost can be further reduced. The shape of the clip 88 is the clip 7.
Although the shape is different from that of No. 6, the function is the same including the point of having a stopper.

Next, the structure in which the retaining portion is provided in the fitting portion of the reinforcing bar holder 10 will be described with reference to FIG. Here, the hook portion is a portion having a structure for hooking the reinforcing bar. In FIG. 7, in the fitting portion 12 of the reinforcing bar holder 10, the protrusion 4 serves as a hooking portion on the holding piece 42.
2a is provided, and the protrusion 44a is provided on the holding piece 44. These convex portions 42a and 44a are formed at positions so that the holding pieces 42 and 44 respectively project toward the inside and, further, hold down the reinforcing bar after fitting. With this structure, the convex portions 42a and 44a allow the holding pieces 42 and 44 to elastically act when the reinforcing bars are fitted, and then the reinforcing bars can be securely hooked. Therefore, due to the positional relationship between the convex portions 42a and 44a, the fitted reinforcing bars are not easily removed. It should be noted that the same effect can be obtained even if the hooking portions (projections 42a, 44a) are formed by ribs. Further, the hooking portion may have a structure in which the reinforcing bars are hooked, other than the rib.

[Embodiment of the Second Invention] Next, in the embodiment of the second invention, a second reinforcing bar holder having two fitting portions in upper and lower two stages is shown in FIG. This will be described with reference to FIG. Here, FIG. 8 is a perspective view showing the appearance of the second reinforcing bar holder. FIG. 9: is a figure which shows the state which fitted the reinforcing bar in the 2nd reinforcing bar holder.

In FIG. 8, the reinforcing bar holder 90 is formed by a processing method such as press working or molding of a metal plate as in the reinforcing bar holder 10. This rebar holder 90
Has a base portion 94 and two fitting portions 92 and 96.
The base portion 94 is a flat plate that connects between the two fitting portions 92 and 96. Although the two fitting portions 92 and 96 are provided in opposite directions, they have the same structure as the fitting portion 12 described in the embodiment of the first invention. Therefore, detailed description of each part is omitted. In the relationship between the fitting portion 92 and the fitting portion 12, the holding pieces 108 and 110 are
44, the support pieces 106, 112 correspond to the support pieces 40, 4
Corresponds to 6. Similarly, regarding the relationship between the fitting portion 96 and the fitting portion 12, the holding pieces 98 and 100 are the holding pieces 42 and 44.
The support pieces 114 and 102 correspond to the support pieces 40 and 46. In addition, each fitting portion 92,
If the hook 96 is provided with a hook, the fitted rebar can be prevented from coming off.

Here, since the base 94 is formed of a flat plate, the reinforcing bars held by the holding pieces 108 and 110 and the reinforcing bars held by the holding pieces 98 and 100 are consequently parallel to each other. Similarly, the reinforcing bars held by the support pieces 106, 112 are parallel to the reinforcing bars held by the support pieces 114, 102. Therefore, it is possible to easily hold the two reinforcing bars in parallel, and FIG. 9 shows a state in which the reinforcing bars are fitted into the reinforcing bar holder 90. Although the base portion 94 is formed as a flat plate, it may be formed by twisting and bending the flat plate (or assigning a member other than the flat plate) to form a predetermined angle. In this way, the reinforcing bar held in the fitting portion 92,
A predetermined angle can be obtained with the reinforcing bar held by the fitting portion 96 without performing any special work.

FIG. 10 shows an example in which the reinforcing bar holder 10 and the reinforcing bar holder 90 are used in combination. This FIG.
As is apparent from the above, by alternately using the reinforcing bar holder 10 and the reinforcing bar holder 90, a plurality of reinforcing bars are held in proper positions in two steps, and are held at right angles in the vertical and horizontal directions. It will be. In an actual reinforced concrete construction or the like, the distance between the reinforcing bar holders 10 is about 1.5 m. Therefore, when assembling the reinforcing bars, there is no need to bind them with the smoothed iron wire, so that the time required for assembling the reinforcing bars can be greatly reduced. Further, since the reinforcing bars are held vertically and horizontally at right angles, it is possible to maintain the linearity of the reinforcing bars. Furthermore, since the two reinforcing bars are held by the fitting portion so as to intersect at a right angle, movement of the reinforcing bar holder 10 is restricted by the two reinforcing bars, and as a result, the reinforcing bar holder 10 itself is also constant. It has the advantage of being held in position.

The structure, shape, size, material, number, arrangement, operating conditions and the like of the other portions of the above-mentioned reinforcing bar holder are not limited to the above-mentioned one form. For example, it is also possible to implement each of the following modes to which the above-described one mode is applied. (1) When the fitting portion of the reinforcing bar holder 10 has a single stage, the base portion 14 is not necessary, and either the fitting portion 12 or the fitting portion 16 may be omitted. In this case, a reinforcing bar holder having the fitting portion 12 and the leg portion 18 or a reinforcing bar holder having the fitting portion 16 and the leg portion 18 is formed. With any of the reinforcing bar holders, the actions and effects described in the above-described embodiments of the invention can be obtained. (2) Instead of the support pieces 40 and 46 of the fitting portion 12, the holding pieces 42 and 44 may be provided with a cutout portion having a shape similar to that of the support pieces 40 and 46. Even in this case, it is possible to reliably hold the reinforcing bar by the notch.

(3) The fitting portions of the reinforcing bar holder may be formed in upper and lower three stages as shown in FIG. 11, and may be similarly formed in more stages (n stages). When specifically forming the upper and lower n stages, the fitting portion 16 shown in FIG.
1) The step may be formed, the uppermost step may be formed by the fitting portion 12, and the fitting portion 12 may be connected by the base portion 14. This way, 1
Since it is possible to hold a plurality of reinforcing bars at appropriate positions with the single reinforcing bar holder, it is possible to significantly reduce the number of reinforcing bar holders required for reinforced concrete construction and the like. Therefore, it is possible to keep the construction cost low. (4) As shown in FIG. 12, the reinforcing bar holder 90 described above.
The fitting portions 92 and 96 may be formed by extending one holding piece in each fitting portion. 12A and 12B are views showing a state where the reinforcing bar holder 90a is arranged between the molds 130 and 132. FIG. 12A is a front view and FIG. 12B is a plan view. Show. Here, the same elements as those in FIG. 8 are denoted by the same reference numerals, and description thereof will be omitted. In this example, the reinforcing bar holder 90a has reinforcing bars 120, 122, 12
4, 126 and holding pieces 98a, 110
The space (wall thickness) between the molds 130 and 132 is maintained at a predetermined distance by a. In this way, one reinforcing bar holder 90a can have a reinforcing bar holding function (a role of a spacer) and an interval holding function between molds (a separator). Therefore, when the reinforcing bar holder 90a is used, the separator is not required, and the construction cost can be further reduced. In addition, not only one holding piece may be extended and formed, but both holding pieces that configure the fitting portion may be extended and formed. In this case, the space between the molds is held by the two holding pieces, so that the space can be held more reliably.

(5) The material for forming the reinforcing bar holder is not limited to metal, but includes plastics (including thermoplastics, thermosetting plastics, fiber reinforced plastics [FRP], etc.), ceramics (including fine ceramics), It is also possible to use other materials such as metal matrix composite material [FRM] and shape memory alloy. When using such a material, it is possible to reduce the weight and cost, especially in the case of plastic, and in the case of metal matrix composite material [FRM] or shape memory alloy, durability and corrosion resistance. It is possible to prevent concrete destruction because it is excellent.
