< embodiment 1 >
Fig. 1 is a diagram showing a first configuration example of a distribution rib unit according to embodiment 1 of the present invention. The distribution rib unit 10 shown in fig. 1 includes a plurality of distribution ribs 11 and a plurality of connecting members 12. A reinforcement spacing L is provided between each of the plurality of distributed reinforcement materials 11.
The distribution reinforcement 11 is a rod made of Fiber-Reinforced plastic (FRP), and is a member for reinforcing a concrete structure. Here, the FRP used for the distribution rib material 11 is not limited to a specific material as long as it has mechanical strength, heat resistance, corrosion resistance, and the like of the distribution rib as a concrete structure. Examples of FRP used for distributing the reinforcement material 11 include: glass fiber reinforced plastic (GFRP: Glass FRP), Carbon fiber reinforced plastic (CFRP: Carbon FRP), Boron fiber reinforced plastic (BFRP: Boron FRP), Aramid fiber reinforced plastic (AFRP: Aramid FRP), and polyethylene fiber reinforced plastic.
Fig. 2 (a) is a diagram showing an external appearance of the distribution rib material 11 applicable to the distribution rib unit 10 shown in fig. 1, and fig. 2 (B) is a schematic diagram showing an example of a reinforcement structure to which the distribution rib unit 10 shown in fig. 1 is applied. Fig. 2 (B) shows a spreader unit 10 including a plurality of spreader bars 11 and a plurality of connecting members 12 shown in fig. 1, and the plurality of spreader bars 11 are arranged substantially perpendicular to the main bar 20.
Here, as shown in fig. 2 (a), it is preferable that the distribution rib 11 has a surface provided with irregularities by nodes or ribs. In a general concrete structure, cracks may occur due to drying or shrinkage. For example, if cracks occur in the surface of the concrete structure in the direction intersecting the distributed reinforcing material 11 as shown in fig. 2 (B), stress indicated by an arrow is generated in the extending direction of the distributed reinforcing material 11, and the width of the cracks is widened by the stress. Therefore, if the irregularities are provided on the surface of the distribution rib 11 as shown in fig. 2 (a), the width of the crack can be suppressed from expanding.
The connecting member 12 is a flexible member that connects the plurality of distributed rib members 11. The connecting member 12 is not limited to a specific form as long as it has mechanical strength, heat resistance, corrosion resistance, and the like to such an extent that it can be transported to and installed in a construction site without breaking. As the connecting member 12, a string, that is, a string-like object is illustrated. Examples of the material of the string-like object include: polypropylene, nylon, cotton, hemp, silk, and rubber. Alternatively, the connecting member 12 may be a wire. The connecting member 12 is fixed to each of the plurality of distribution ribs 11 so that a reinforcement interval L is provided between the mutually adjacent distribution ribs 11. Here, the method of fixing the distribution rib 11 and the connecting member 12 is not limited to a specific method. The distribution rib 11 and the connecting member 12 may be fixed by integrally joining the connecting member 12 and the distribution rib 11, or may be fixed by an adhesive.
The distribution reinforcement 11 is used as a substitute for a conventional reinforcement forming a concrete structure. The conventional reinforcing bars as the distributed reinforcing material have a problem of low transportability because of heavy weight. Further, in the conventional reinforcement, it is necessary to arrange a heavy reinforcement at an accurate position, and there is a problem that a burden on an operator is large. Further, in the work of fixing the main bar and the distribution bar at the intersection by making the longitudinal directions of the plurality of heavy bars different, the member to be handled is heavy, and therefore, there is a problem that the burden on the worker is large. In this way, if reinforcing steel is used as the distribution reinforcement, there is a problem that workability in reinforcing the reinforcement is low.
On the other hand, in order to reinforce a concrete structure, a wire mesh called a welded wire mesh or a steel mesh is sometimes used. The wire mesh is a mesh-shaped wire mesh in which wires are arranged orthogonally and intersections of the orthogonal wires are welded. When a wire mesh is used to reinforce a concrete structure, the number of steps increases due to the welding step. Further, the wire mesh manufactured through the welding process has a planar shape, and has a problem of low transportability.
Therefore, if the spreader bar 11 included in the spreader bar unit 10 is made of lightweight FRP as in the present embodiment, the weight of each spreader bar can be reduced, and the spreader bar unit 10 can be reduced. Further, if the distribution rib 11 is made of FRP having high strength, the diameter of the distribution rib 11 can be made small. By making the distribution rib material 11 thin, the transportability of the distribution rib unit 10 made into a bundle shape as described later can be improved. Therefore, the distribution rib unit 10 can be easily transported to the construction site, and the distribution rib unit 10 can be easily installed in the construction site. In this way, workability in reinforcement of the reinforcement unit 10 can be improved.
As described above, the distribution rib unit 10 is set with the rib arrangement interval L based on the structural design, and the plurality of distribution ribs 11 are connected by the connecting member 12. Therefore, when the distribution rib unit 10 is provided, the reinforcement interval L is secured between the plurality of distribution ribs 11, and thus reinforcement can be performed without using professional knowledge and skilled techniques regarding reinforcement.
Fig. 3 is a schematic view showing an example of arrangement of the binding portions 13 in the reinforcement structure shown in fig. 2 (B). Conventionally, each of the intersections of the main ribs and the distribution ribs has been bundled as a principle, but in the present embodiment, since the plurality of distribution rib materials 11 of the distribution rib unit 10 are connected by the plurality of connecting materials 12, as shown in fig. 3, the number of bundling sections 13 that bundle the main ribs 20 and the distribution rib materials 11 can be significantly reduced, and workability can be improved.
The distribution rib units 10 can equalize intervals between the distribution ribs 11 adjacent to each other. Therefore, in the distribution rib unit 10, when the number of the distribution ribs 11 is 3 or more, the reinforcement interval L provided between the mutually adjacent distribution ribs 11 can be accurately adjusted. However, the distribution rib unit of the present invention is not limited to the form in which the intervals between the adjacent distribution ribs are equal.
It should be noted that the distribution rib 11 may be of a solid structure or a hollow structure. Fig. 4 is a cross-sectional view of the distribution rib 11 at IV-IV in fig. 1. In fig. 4, a distribution rib 11 of hollow construction is shown. In fig. 4, the distribution rib 11 has a hollow structure that surrounds the space 111 through the side portion 110. The space 111 is formed inside the distribution rib 11 along the direction in which the distribution rib 11 extends. When the distribution rib 11 has a hollow structure, the bending strength is improved as compared with a case where the distribution rib has a solid structure with the same weight. Further, if the distribution rib 11 has a hollow structure, it can be lighter than a solid structure having the same bending strength, and the transportability is improved.
Fig. 5 is a diagram showing the distribution rib unit 10 bundled into a bundle shape. When the plurality of distributed rib materials 11 of the distributed rib unit 10 are bundled into a bundle shape as shown in fig. 5, the distributed rib unit 10 can be conveyed in the bundle shape, and the conveyance performance is dramatically improved. Here, as the binding material, a binding material not shown may be used. Here, as the binding material, a string, that is, a string-like object is exemplified as in the case of the connecting material 12. Examples of the material of the string-like object include: polypropylene, nylon, cotton, hemp, silk, and rubber.
The distribution rib unit 10 made into a bundle shape as described above is transported to a construction site and unbundled. That is, the binding material is loosened at the construction site. Then, the released distributed rib unit 10 is spread in a planar shape and fixed so that the distributed rib material 11 is orthogonal to the main rib. According to the reinforcement construction method using the distributed rib units formed into the bundle shape, reinforcement can be performed by unbundling, spreading, and fixing the distributed rib units formed into the bundle shape on the construction site. Therefore, workability, specifically, assemblability can be improved. Since the reinforcement interval L is secured between the plurality of distributed reinforcement members 11, it is not necessary to use expertise and skilled technique for reinforcement, and even an operator who does not have expertise and skilled technique for reinforcement can perform reinforcement.
As described above, according to the distributed rib unit of the present embodiment, workability in reinforcement can be improved.
