Description

  The present invention relates to a reinforcing bar for reinforcing bar used in, for example, a concrete pile, a hoop bar, and a reinforcing bar bar using them.

  Conventionally, for example, a steel bar used for a concrete pile has been developed (for example, Patent Document 1).

  In general, a reinforcing bar rod consists of a plurality of main bars, which are rod-shaped materials extending in the longitudinal direction, a circular hoop bar for fixing the main bars in a circular shape, and a main bar arranged in a circular shape like the hoop bar. The main frame and the hoop line, and the main bar and the reinforcing frame are fixed to each other using a means such as welding at a predetermined position.

  According to a conventional method for manufacturing a reinforcing bar rod, a plurality of main bars are temporarily arranged on the inner periphery of a hoop bar or a reinforcing frame using an assembly jig, and then the main bar and the hoop bar, Then, the main bar and the reinforcing frame are fixed to each other by means of welding or the like, thereby completing the reinforcing bar rod. And as shown in FIG. 7, the completed reinforcing bar 200 is installed in the hole H for installing a concrete pile using a crane etc. As shown in FIG.

  Of course, in addition to the above-described manufacturing method, for example, when assembling the reinforcing bar rod 202 having a relatively large diameter, an operator enters the bottom of the hole H formed in advance as shown in FIG. While raising the main bar 210 of the book and assembling the scaffold, the hoop bar 212 and the reinforcing frame 214 may be arranged and fixed to the main bar as appropriate.

<Structure of reinforcing bar>

  With reference to FIG. 1 and FIG. 2, the whole structure of the reinforcing bar rod 100 concerning this Embodiment is demonstrated. The reinforcing bar rod 100 of the present embodiment has a double rod structure, which is roughly an outer main bar 110, an inner main bar 120, a reinforcing frame 130, a hoop bar 140, and a fixed hardware 150 used as necessary. And.

  The reinforcing bar 100 is a structure used for shear reinforcement of a concrete pile supporting a high-rise building or a bridge. After the reinforcing bar 100 is installed in a hole drilled in the ground, a concrete pile is completed by assembling a mold or the like around the reinforcing bar 100 and pouring (casting) concrete into the mold.

  The outer main reinforcement 110 is a reinforcing bar that mainly bears the tensile force applied to the concrete pile. In the present embodiment, a long reinforcing bar having a round cross section is used as the outer main reinforcing bar 110 (of course, the shape of the outer main reinforcing bar 110 is not limited to this). The plurality of outer principal bars 110 are arranged on a virtual circle VC1 centered on a certain point C in a cross section whose longitudinal directions are substantially parallel to each other and orthogonal to the longitudinal direction. Thus, a substantially cylindrical structure is configured by the plurality of outer principal bars 110. In addition, the shape of the structure formed by the plurality of outer principal bars 110 is not limited to a substantially cylindrical shape, and may be a substantially rectangular tube shape or other shapes.

  The inner main bar 120 is basically the same reinforcing bar as the outer main bar 110. A plurality of inner main bars 120 are arranged on an inner virtual circle VC2 that is concentric with the virtual circle VC1 in which the outer main bar 110 is arranged and has a smaller diameter than the virtual circle VC1. Thereby, a substantially cylindrical structure is configured by the plurality of inner main bars 120. As in the case of the outer main reinforcement 110, the shape of the structure formed by the plurality of inner main reinforcements 120 is not limited to a substantially cylindrical shape, and may be a substantially rectangular tube shape or other shapes. Moreover, the shape of the structure of the outer principal muscle 110 and the inner principal muscle 120 may be different.

  As shown in FIG. 3, the reinforcing frame 130 includes a main body member 132, a second main body member 134, a fixing member 135, a main bar holding member 136, and a second main bar holding member 138. The number of reinforcing frames 130 is determined according to the lengths of the outer main bars 110 and the inner main bars 120 used (three reinforcing frames 130 are used in the example of FIG. 1). In view of the strength of the reinforcing bar 100, the interval between the reinforcing frames 130 adjacent to each other is preferably within 3 m.

  The main body member 132 is a belt-like member surrounding the side periphery of a substantially cylindrical structure composed of a plurality of outer principal bars 110, and is formed in a substantially circular shape by being bent with a predetermined curvature. Similar to the arrangement of the outer main bar 110 and the inner main bar 120, the appearance shape of the main body member 132 is not limited to a substantially circular shape, and is substantially square or other shapes according to the arrangement of the outer main bar 110 or the inner main bar 120. It may be “annular”. That is, throughout the present specification, “annular” is a concept that includes not only a substantially circular shape but also a substantially square shape. Further, the term “annular” is not limited to the case where both ends of the member are connected to each other as shown in the figure, and is a concept including the case where both ends are separated from each other.

  The second main body member 134 is a band-shaped member that surrounds the side periphery of the substantially cylindrical structure formed by the plurality of inner main bars 120 and is substantially bent by being bent with a predetermined curvature larger than that of the main body member 132. It is formed in a circular shape and is disposed inside the main body member 132.

  The fixing member 135 is a member that fixes the main body member 132 and the second main body member 134 to each other. Specifically, one end of the fixing member 135 is connected and fixed inside the main body member 132, and the other end of the fixing member 135 is connected and fixed outside the second main body member 134. In the present embodiment, four fixing members 135 are used, and by these fixing members 135, the second main body member 134 is concentric with the main body member 132 and is the same as a virtual plane including the periphery of the main body member 132. The second main body member 134 is disposed at a position including the periphery of the second main body member 134 on the plane. Of course, the structure of the fixing member 135 is not limited to this, and the main muscles 110 and 120 are fixed to each other by shifting the main body member 132 and the second main body member 134 in the longitudinal direction of the main bars 110 and 120 and fixing them together. The workability provided on the holding members 136 and 138 can also be improved.

  The main bar holding member 136 is a member that holds the outer main bar 110 in a predetermined position, and protrudes toward the inner side of the main body member 132. The main reinforcement holding members 136 are attached to one main body member 132 by the number of the outer main reinforcements 110.

  By the way, as will be described later, since the reinforcing frame 130 is used standing upright from the ground when assembling the reinforcing bar 100, the main body member 132 has an upper end 132A and a lower end 132B. . That is, when the reinforcing frame 130 is erected on the ground, the position on the ground side is the lower end 132B, and the position facing this is the upper end 132A.

  The shapes of the plurality of main bar holding members 136 are classified into two types depending on the position of the main body member 132 to which they are attached. The main bar holding member 136B protruding from the lower half of the main body member 132 (that is, the lower half including the lower end 132B when divided by a virtual horizontal line VH passing through the center C of the main body member 132 in an upright state) is substantially It is formed in a straight line, and one end thereof is connected to the inside of the main body member 132 as described above, and the other end is disposed so as to extend toward the center C of the virtual circle VC1.

  Further, the main bar holding member 136A protruding from the upper half of the main body member 132 (that is, the upper half including the upper end 132A when divided by the virtual horizontal line VH passing through the center C of the main body member 132 in the standing state) It has the 1st member 162 formed in the substantially linear form, and the 2nd member 164 extended in the direction substantially orthogonal to the 1st member 162 from the end of the said 1st member 162 concerned. The other end of the first member 162 is connected to the inside of the main body member 132, and one end of the first member 162 is disposed so as to extend toward the center C of the virtual circle VC1. Therefore, the second member 164 is disposed so as to extend substantially in parallel with the tangent VT1 of the virtual circle VC1 that is the arrangement reference of the main body member 132 and the outer principal muscle 110.

  As described above, by properly using the shape of the main bar holding member 136 depending on the position where it is attached to the main body member 132, the outer main bar 110 can be accurately and easily placed at a desired position when the reinforcing bar rod 100 is assembled.

  That is, in the case of the outer main reinforcement 110 arranged in the lower half of the main body member 132, by arranging the outer main reinforcement 110 at the upper corner 166 formed by the inner surface of the main body member 132 and each main reinforcement holding member 136B, The outer main bar 110 is held by the inner surface of the main body member 132 and the main bar holding member 136B. That is, the main bar holding member 136B needs to protrude from the inner surface of the main body member 132 slightly below the position where the outer main bar 110 is disposed.

  Further, in the case of the outer main reinforcement 110 arranged in the upper half of the main body member 132, the outer main reinforcement 110 is arranged on the hook-shaped portion 168 formed by the first member 162 and the second member 164 of the main reinforcement holding member 136A. Thus, the outer main muscle 110 is held by the main bar holding member 136A. That is, the main bar holding member 136 needs to protrude from the inner surface of the main body member 132 slightly below the position where the outer main bar 110 is disposed.

  The second main bar holding member 138 is a member that holds the inner main bar 120 in a predetermined position, and protrudes from the inner side of the second main body member 134. The second main bar holding members 138 are attached to one second main body member 134 by the number of inner main bars 120.

  Similar to the main body member 132, the second main body member 134 also has an upper end 134A and a lower end 134B. That is, when the reinforcing frame 130 is erected on the ground, the position on the ground side is the lower end 134B, and the position facing this is the upper end 134A.

  The shape of the plurality of second main bar holding members 138 is basically the same as that of the main bar holding member 136 described above, and is divided into two types according to the position of the second main body member 134 to which they are attached. The second main reinforcement projecting from the lower half of the second main body member 134 (that is, the lower half including the lower end 134B when divided by a virtual horizontal line VH passing through the center C of the second main body member 134 in the standing state) The holding member 138B is formed in a substantially linear shape, and is disposed so that one end thereof is connected to the inside of the second main body member 134 and the other end extends toward the center C of the virtual circle VC2. .

  Further, the second main body member 134 protrudes from the upper half (that is, the upper half including the upper end 134A when divided by the virtual horizontal line VH passing through the center C of the second main body member 134 in the standing state). The main bar holding member 138A includes a first member 172 formed in a substantially linear shape, and a second member 174 extending from one end of the first member 172 in a direction substantially orthogonal to the first member 172. The other end of the first member 172 is connected to the inside of the second main body member 134, and one end of the first member 172 is disposed so as to extend toward the center of the virtual circle VC2. Therefore, the second member 174 is disposed so as to extend in parallel with the tangent line VT2 of the virtual circle VC2 serving as a placement reference for the second main body member 134 and the inner main muscle 120.

  As described above, by properly using the shape of the second main bar holding member 138 depending on the position to be attached to the second main body member 134, the inner main bar 120 can be accurately and easily arranged at a desired position when the reinforcing bar rod 100 is assembled. it can.

  That is, in the case of the inner main bar 120 arranged in the lower half of the second main body member 134, the inner main bar 120 is formed at the upper corner 176 formed by the inner surface of the second main body member 134 and each second main bar holding member 138B. The inner main bar 120 is held by the inner surface of the second main body member 134 and the second main bar holding member 138B. That is, the second main bar holding member 138B needs to protrude from the inside of the second main body member 134 slightly below the position where the inner main bar 120 is disposed.

  Further, in the case of the inner main muscle 120 arranged in the upper half of the second main body member 134, the inner main muscle 120 is formed on the hook-shaped portion 178 formed by the first member 172 and the second member 174 of the second main muscle holding member 138 </ b> A. The inner main muscle 120 is held by the second main bar holding member 138A. That is, the second main bar holding member 138A needs to protrude from the inner surface of the second main body member 134 slightly below the position where the inner main bar 120 is disposed.

  As shown in FIG. 4, the hoop muscle 140 has a first hoop muscle 142 and a second hoop muscle 144. The first hoop bar 142 is a reinforcing bar having a diameter smaller than that of the outer main bar 110 wound between the reinforcing frames 130 on the side periphery of the substantially cylindrical structure formed by the plurality of outer main bars 110. The first hoop muscle 142 and the plurality of outer principal muscles 110 are fixed to each other at a position where each outer principal muscle 110 and the first hoop muscle 142 are close to each other.

  The second hoop bar 144 is a reinforcing bar having a diameter smaller than that of the inner main bar 120 wound between the second main body members 134 on the side periphery of the substantially cylindrical structure formed by the plurality of inner main bars 120. is there. The second hoop muscle 144 and the plurality of inner main muscles 120 are fixed to each other at a position where each inner main muscle 120 and the second hoop muscle 144 are close to each other.

  The fixed hardware 150 includes an outer main bar 110 and a main body member 132 (see FIG. 5. For convenience of explanation, the fixed hardware 150 is illustrated only in FIG. 5 and is omitted in other drawings). And, it is a hardware used for fixing the inner main bar 120 and the second main body member 134 to each other. In the present embodiment, the same type of fixed hardware 150 is used for fixing the outer main muscle 110 and the inner main muscle 120, but instead, different types of fixed hardware 150 may be used. . Alternatively, the outer main bar 110 and the main body member 132, and the inner main bar 120 and the second main body member 134 may be fixed to each other using other means such as welding without using the fixed hardware 150.

  The same applies to the method of fixing the first hoop muscle 142 and the outer main muscle 110 and the second hoop muscle 144 and the inner main muscle 120 to each other, and the fixed hardware 150 may be used, or other types. Other means such as fixed hardware and welding may be used.

<Manufacturing method of double rebar bar according to this embodiment>
Next, a method for manufacturing the double reinforcing bar 100 according to the present embodiment will be described. First, the plurality of reinforcing frames 130 are arranged in a state where they are raised with respect to the ground at predetermined intervals. At this time, the reinforcing frame 130 is erected with the lower end 132B of the main body member 132 and the lower end 134B of the second main body member 134 facing downward.

  Thereafter, the outer main bar 110 and the inner main bar 120 are arranged at predetermined positions on the reinforcing frame 130. More specifically, the outer main reinforcing bar 110 is bridged between the reinforcing frames 130 so that the distal end penetrates between the main body member 132 and the second main body member 134, and then the corner portion 166 or the saddle shape. The parts 168 are arranged respectively. Further, after the inner main bars 120 are spanned between the reinforcing frames 130 so as to penetrate the inside of the second main body member 134 in a necessary number, the corners 176 or the hook-shaped portions 178 are placed one by one. Placed in.

  After the outer main bar 110 and the inner main bar 120 are arranged at predetermined positions on the reinforcing frame 130, the outer main bar 110 and the inner main bar 120 are connected to the reinforcing frame 130 (more precisely, the main body member 132 and the second main body using the fixed hardware 150. It fixes to member 134).

  At the same time, the hoop muscle 140 (the first hoop muscle 142 and the second hoop muscle 144) is fixed to the outer main muscle 110 and the inner main muscle 120 as necessary.

  As described above, the double reinforcing bar rod 100 is completed while being laid on the ground. Production of the reinforcing bar 100 is generally performed at a site where a concrete pile is installed, but it may be transported to the installation site after being manufactured from the installation site at a remote factory or the like.

  Then, as shown in FIG. 6, the hole H for installing a concrete pile is dug in the ground, and the reinforcing bar 100 is installed in the hole H using a heavy machine etc. Then, a concrete formwork is provided around the reinforcing bar 100 and concrete is poured into the concrete pile to complete the concrete pile.

<Characteristics of rebar bar according to this embodiment>
According to the reinforcing bar rod 100 according to the present embodiment, there is no need to temporarily arrange a plurality of main bars on the inner periphery of the reinforcing frame using an assembly jig as in the prior art. The problem that it becomes difficult to remove the tool can be solved.

  In recent years, double-bar reed rods with a combination of large-diameter and small-diameter rebar rods have also been used for concrete piles. A technique is adopted in which, after producing a heel and a small-diameter rebar rod separately, the small-diameter rebar rod is suspended from above the large-diameter rebar rod previously installed in the hole H. However, with such a technique, it is difficult to fix the small-sized reinforcing bar rod that is lifted and unstable to the large-diameter reinforcing rod rod with high accuracy.

  In this regard, according to the reinforcing bar rod 100 according to the present embodiment, the double reinforcing bar rod 100 having the plurality of main body members 132 and 134 is used to manufacture the double reinforcing bar rod 100, thereby allowing a large diameter reinforcing bar rod and a small diameter. Conventionally combining large and small rebar rods, such as hanging a small diameter rebar rod from above the large diameter rebar rod previously installed in the hole H. There is no need to adopt a construction method. For this reason, the double rebar rod 100 can be manufactured with high accuracy. In addition, work in an unstable state, such as welding and fixing a small-diameter rebar rod in a suspended state to a large-diameter rebar rod, is no longer necessary. It can be shortened. As a result, the cost related to the construction can also be reduced.

  In addition, since the main bars 110 and 120 can be arranged with high accuracy, the positions of the main bars 110 and 120 protruding from the top of the manufactured concrete pile are accurately determined. As a result, it is also possible to systematically avoid interference between the reinforcement of the underground beam and the main bars 110, 120 arranged in a direction substantially perpendicular to the direction in which the concrete pile extends above the concrete pile. It becomes.

<Modification>

It may be. Further, the main bar holding members 136 and 138 may be projected from both the reinforcing frame 130 and the hoop bar 140. That is, although not shown, the first hoop muscle 142 is constituted by a first hoop muscle main body member and a first main muscle holding member, and the second hoop muscle 144 is constituted by a second hoop muscle main body member and a second main muscle holding member. It will consist of As described above, when the main bar holding members 136 and 138 are protruded from the hoop bar 140 as described above, a single hoop bar may be used as long as a single bar bar is manufactured. If it is manufactured, it is sufficient to use a corresponding number of hoop muscles. Moreover, when using the several hoop muscles 142 and 144 with which the main reinforcement holding member protruded, it is necessary to use the hoop muscle fixing member (not shown) which fixes each hoop muscle 142,144. Furthermore, the direction in which the holding member protrudes from each of the hoop bars 142 and 144 may be mixed inside or outside.
