Description

  The present invention relates to a structure reinforcing member.

  Conventionally, a steel plate winding method has been widely used as a measure for reinforcing a structure. In this steel plate winding method, a plurality of reinforcing steel plates (reinforcing plates) are arranged around a structure, such as a column, a beam, or a bridge pier of a building, and welding ends to connect adjacent steel plates. At the same time, the space between the reinforcing steel plate and the structure is filled with epoxy resin, mortar or the like.

  Thereby, the steel plate for reinforcement installed so as to surround the structure is integrated with the structure, and the bending strength, the shear strength, and the toughness of the structure can be significantly improved. In addition, it is possible to significantly improve the resistance to the bulging output acting in the radial direction of the structure such as a column due to a load such as compression.

  On the other hand, as shown in FIG. 8, the joint members 2 and 3 are integrally provided at the end of the reinforcing steel plate 1, and the joint members 2 and 3 at the end of the adjacent reinforcing steel plate 1 are overlapped and engaged. In addition, there is one configured to bolt and couple the pair of joint members 2 and 3 (see, for example, Patent Document 1 and Patent Document 2). Further, the pair of joint members 2 and 3 are formed with the concavo-convex portions (concave portion 5 and convex portion 4) 2a and 3a on the overlapping surfaces engaged with each other, and the concave portions of the pair of joint members 2 and 3 are formed The end portions of the reinforcing steel plates 1 adjacent to each other can be firmly connected by meshing (engaging) the projections 5 with the projections 4.

  Here, in the conventional structural reinforcement members 7 and 8, as shown in FIG. 9, the joint members 2 and 3 are formed so as to secure a predetermined thickness at each portion from the distal end to the proximal end. And the overlapping surfaces 2b, 2c, 3b, 3c on the tip end side and the base end side across the uneven portions 2a, 3a (the overlapping surface 2b of the tip end engaging portions 2d, 3d and the base end engaging portions 2e, 3e , 2c, 3b, 3c) are formed in a planar shape, and a reference plane P including the center in the thickness direction of the reinforcing steel plate 1 in the plane, wherein the overlapping surfaces 2b, 2c, 3b, 3c on the distal end side and the proximal end side The joint members 2 and 3 are integrally attached to the end of the reinforcing steel plate 1 so as to be disposed on the upper side.

  Further, the plurality of convex portions 4 and the plurality of concave portions 5 are formed to have substantially the same diameter and the same size, with the amount of protrusion and the amount of recess being substantially the same on the basis of the reference surface P.

  Then, in the conventional structural reinforcement members 7 and 8 configured in this manner, an external force acts on the structure due to an earthquake or the like, and the very large tensile force R in the direction of separating the connected reinforcing steel plates 1 from each other. Acts on the pair of joint members 2 and 3 (joint structure), the distal end engaging portions 2d and 3d and the proximal end engaging portions 2e and 3e are separated as shown in FIG. Warpage deformation S may occur.

  Further, when a very large tensile force R acts to cause a warping deformation S in the joint members 2 and 3, the tensile force R will be received only by the concavo-convex portions 2a and 3a in the middle part, and the tip engagement portion 2d, The uneven portions 2a and 3a on the 3d side and the proximal end engaging portions 2e and 3e do not contribute to the proof stress (the tolerance proof stress and the ultimate proof stress) of the joint structure.

  An object of this invention is to provide the member for structure reinforcement which makes it possible to raise proof stress conventionally, in view of the said situation.

  In order to achieve the above object, the present invention provides the following means.

  The member for reinforcing a structure according to the present invention is a member for reinforcing a structure, which is disposed adjacent to the surface of the structure, is filled with a filler between the structure and the structure, and is integrally installed on the structure. And a joint member integrally provided at an end of the reinforcing plate and connecting the ends of the adjacent structural reinforcement members, and the joint member is adjacent to the joint member.

  In the structure reinforcing member of the present invention, each joint member makes the concave portion on the distal end engaging portion side larger than the concave portion on the proximal end engaging portion side, and engages the convex portion on the proximal end engaging portion Even if the joint member is warped or deformed due to the application of a very large tensile force by being formed to be larger than the projections on the part side, the pair of projections is engaged with the large recesses. It is possible to hold the engagement state between the tip end engaging portion sides of the joint members and the end end engaging portion sides of the joint members.

  As a result, it becomes possible to receive the tensile force not only by the concavo-convex part of the intermediate part engaged with each other of the pair of joint members but also by the concavo-convex part of the distal end engaging part side and the proximal end engaging part side.

  Therefore, it becomes possible to make the convex part and concave part of the tip end engaging part side and the base end engaging part side surely contribute to the proof stress of the joint structure, and the proof stress as a structure reinforcing member is improved compared to the conventional case.

  Furthermore, in each of the joint members 12 and 13, bolt insertion holes (not shown) are formed through the distal end engaging portions 12d and 13d and the proximal end engaging portions 12e and 13e, respectively. Then, when the joint member 12 of one structure reinforcing member A1 and the joint members 13 of the other structure reinforcing member A2 are superimposed, the bolt insertion holes of the tip end engaging portion 12 d of the one joint member 12 And the bolt insertion hole of the proximal end engagement portion 13e of the other joint member 13 communicate with each other, and the bolt insertion hole of the proximal end engagement portion 12e of one joint member 12 and the distal end engagement portion 13d of the other joint member 13 It communicates with the bolt insertion hole of. At the same time, a bolt is inserted into the bolt insertion hole from the inner surface side, and a nut is screwed and fastened to the bolt protruding from the bolt insertion hole to the outer surface side via a washer.

  The joint member may not necessarily be formed by providing a bolt insertion hole. That is, you may comprise so that a pair of coupling member may be connected only by making the uneven part of each other engage. Also in this case, the end portions of the pair of joint members 12 and 13 and the end of the one structural reinforcing member A1 and the other structural reinforcing member A2 are firmly connected and fixed.

  On the other hand, in the structural member reinforcing members A1 and A2 of the present embodiment, the joint members 12 and 13 are the concave portions 5 (5a) on the distal end engaging portions 12d and 13d side and the concave portions on the proximal end engaging portions 12e and 13e side (Concave part in the middle part of the concavo-convex parts 4a, 5a) 5 (5b) is formed larger and the convex part 4 (4a) on the base end engaging part 12e, 13e side is convex on the tip engaging part 12d, 13d side It is formed to be larger than the part (convex part in the middle part of the concavo-convex parts 4a, 5a) 4 (4b).

  As a result, the area of the engagement surfaces 14 and 15 on the tip end engagement portions 12 d and 13 d side and the base end engagement portions 12 e and 13 e side of the joint members 12 and 13 with which the uneven portions 4 a and 5 a mesh and contact The total engagement area) is formed to be larger than the area of the engagement surfaces 14 and 15 in the middle of the uneven portions 4a and 5a.

  Here, the joint members 12 and 13 of the present embodiment are manufactured by rolling a steel material.

  Specifically, as shown in FIG. 4, for example, as shown in FIG. 4, the joint members 12 and 13 have a pair of work rolls 17 and 18 for rolling which are disposed with a predetermined interval while the rotational axes O1 and O2 are parallel. It manufactures using the rolling processing apparatus 19 provided.

  In addition, one work roll 17 is formed in a cylindrical shape with a constant outer diameter in the direction of the rotation axis O1.

  The other work roll 18 is formed in a substantially frusto-conical shape in which the diameter of the machined portion 18 a decreases from one side to the other side toward the rotation axis O 2. The other work roll 18 forms an engagement surface of the joint members 12 and 13 on the surface of the processing portion 18a at right angles to the rotation axis O2, and includes the recess 5 and the protrusion including the engagement surfaces 14 and 15. A plurality of annular projections 21 for forming 4 and a plurality of annular projections 21 provided on the front side and the rear side in the direction of the rotation axis O1 across the plurality of annular projections 21 respectively. A distal end engaging portion forming portion 22 and a proximal end engaging portion forming portion 23 for forming the proximal end engaging portions 12e and 13e, respectively, are provided.

  Furthermore, in the present embodiment, among the plurality of annular projections 21, the annular projection 21 (21 a) on the proximal end engaging portion forming portion 23 side is longer in projection length and width than the other annular projections 21 (21 a). Etc. are formed. In addition, the recess between the annular projection 21 (21b) on the tip engaging portion forming portion 22 side and the tip engaging portion forming portion 22 is formed with the recess depth, width, etc. made larger than the other portions. ing.

  Then, in the rolling processing apparatus 19, when the steel material (workpiece) 20 is fed between the pair of work rolls 17, 18, the annular projection 21 of the processed portion 18a of the other work roll 18 and the tip engagement portion forming portion 22. The base end engaging portion forming portion 23 presses against one surface of the steel material 20 and bites, and the steel material 20 is rolled between the pair of work rolls 17 and 18 while the recess 5 and one surface are formed on one surface. Concavo-convex parts 12a and 13a which consist of convex part 4, tip end engaging parts 12d and 13d, and base end engaging parts 12e and 13e are formed.

Further, in the present embodiment, at this time, the annular projection 21 (21a) on the side of the base end engaging portion 23 is formed so as to have a projecting length, width and the like larger than other annular projections 21 (21a). It is done. Furthermore, the recess 24 between the annular projection 21 (21b) on the tip engaging portion forming portion 22 side and the tip engaging portion forming portion 22 has a larger recess depth, width, etc. than the recesses of other portions. It is formed.
Therefore, the large convex portion 4 or the large concave portion is formed on one surface of the distal end engaging portions 12d and 13d and the proximal end engaging portions 12e and 13e of the steel member 20 by the large annular projection 21 (21a) and the large recess 24. 5 is formed.

  Then, bolt insertion holes are formed in the rolled steel material 20 as described above, and if necessary, the outer surface and the inner surface are cut, or bolts are attached in advance by spot welding, etc. The manufacture of the coupling members 12, 13 is completed.

  Next, an example of a method of constructing a reinforcing structure B of a structure provided with the structure reinforcing members A1 and A2 of the present embodiment configured as described above will be described.

  First, as shown in FIG. 5, for example, the mounting jig 31 is assembled and fixed to the root portion of the column (structure) 10 erected on the base portion 30. The mounting jig 31 has a base 32 fixed to the base and a base end fixed to the base 32 so that the base end can be freely rotated, and two ladder-like reinforcing plate mounting portions that rotate in the direction of holding the column 10 And 33 (mounting jig assembling step).

  Then, the reinforcing plate mounting portion 33 of the mounting jig 31 is turned to be lowered onto the base portion 30, and the structural reinforcing members A1 and A2 are respectively placed on the inner surface side on these reinforcing plate mounting portions 33. Place it on top. As shown in FIGS. 5 and 6, the reinforcing plate mounting portion 33 is rotated in the direction (the direction of the arrow in the drawing) in which the column 10 is held, and the structural reinforcing members A1 and A2 in the mounted state are Let each stand up. Thus, the pair of structure reinforcing members A1 and A2 are disposed to surround the column 10 in a state in which the pair of structure reinforcing members A1 and A2 face each other and in which a certain gap is provided between the columns 10 Standing process).

  Also, at this time, on the inner surface side of the upper end portion of the pair of structure reinforcing members A1 and A2 connected, filling such as a spacer for securing a fixed gap with the column 10, mortar injected in a later step A sealing member or the like for preventing the agent 11 from leaking is attached.

  Then, while erecting the pair of structure reinforcing members A1 and A2 as described above, the joint members 12 and 13 of one structure reinforcing member A1 and the other structure reinforcing member A2 are overlapped, The uneven portions 12a, 13a of the joint members 12, 13 are engaged with each other, and the distal end engaging portions 12d, 13d and the proximal end engaging portions 12e, 13e are engaged with each other. Further, the joint members 12 and 13 are fixedly connected to each other by bolts and nuts (reinforcing plate connecting step).

  Next, as shown in FIG. 7, the assembled structure reinforcing members A1 and A2 are lifted upward along the column 10, and the upper ends of the pair of structure reinforcing members A1 are beams on the column 10 Contact the lower part of 34. At this time, the temporary fixing bolts are made to pass through the temporary fixing through holes formed in the lower part of the structure reinforcing members A1 and A2, and the temporary formed in the column 10 at a position corresponding to the temporary fixing through holes. By inserting into the locking holes, the structural reinforcement members A1 and A2 are temporarily fixed so as not to slip off. Further, the reinforcing plate standing process, the reinforcing plate connecting process and the reinforcing plate lifting process are repeatedly performed to attach a plurality of structural reinforcing members A1 and A2 in a temporarily fixed state over the entire peripheral surface of the column 10 (reinforcing plate Lifting process).

  After temporarily fixing all the structure reinforcing members A1 and A2, these structure reinforcing members A1 and A2 are finally fixed. Further, the upper end portions of these structure reinforcing members A1 and A2 are respectively sealed using sealing members. The structural reinforcing members A1 and A2 vertically adjacent to each other are appropriately connected and fixed by welding or the like (reinforcing plate fixing step).

Next, a filler 11 such as mortar is injected into the gap between the structure reinforcing members A1 and A2 and the column 10 and filled, and cured until the filler 11 is sufficiently solidified (filler injection step).
Finally, the mounting jig 31 is disassembled, and the construction of the reinforcing structure B of the structure of this embodiment is completed.

  And in structural reinforcement members A1 and A2 (reinforcement structure B of a structure) of the present embodiment configured as described above, each joint member 12 and 13 is a concave portion 5 on the tip engaging portion 12d and 13d side ( 5a) is made larger than the concave portion 5 (5b) on the proximal end engaging portion 12e, 13e side, and the convex portion 4 (4a) on the proximal end engaging portion 12e, 13e side is on the distal end engaging portion 12d, 13d side It is formed to be larger than the convex portion 4 (4b).

  Along with this, the areas of the engagement surfaces 14 and 15 on the tip end engagement portions 12 d and 13 d side and the base end engagement portions 12 e and 13 e side of the joint members 12 and 13 with which the uneven portions 4 a and 5 a mesh and surface contact In a state where the area of the intermediate surfaces of the uneven portions 4a and 5a is larger than the area of the engaging surfaces 14 and 15, the uneven portions 4a and 5a are engaged, and the joint members 12 and 13 are connected to each other.

  Thereby, an external force acts on the structure 10 due to an earthquake or the like, and a very large tensile force R in a direction to separate the connected structural member reinforcing members A1 and A2 acts on the pair of joint members 12 and 13. Even if there are, the large concave portion 5 (5a) of the tip end engaging portions 12d and 13d of one joint member 12 and 13 and the large convex portion 4 on the proximal end engaging portion 12e and 13e side of the other joint members 12 and 13 Since (4a) is engaged and the contact area of the engagement surfaces 14 and 15 is made large, the engaged state between the distal end side and the proximal end of each joint member 12 and 13 is maintained. Therefore, not only the concavo-convex portions 12a and 13a in the intermediate portion of the pair of joint members 12 and 13 engaged with each other, but also the concavo-convex portions 12a and 13a on the distal end engaging portions 12d and 13d side and the proximal end engaging portions 12e and 13e side Can also receive the tensile force R.

  Therefore, the engagement between the uneven portions 12a and 13a of the pair of joint members 12 and 13 and between the distal end engaging portions 12d and 13d and the proximal end engaging portions 12e and 13e become difficult to disengage, and a very large tensile force R acts. The deformation resistance of the joint members 12 and 13 at the time of bonding, and hence the yield strength, is increased.

  That is, in the structure reinforcing members A1 and A2 of the present embodiment, the entire uneven portions 12a and 13a including the distal end engaging portions 12d and 13d and the proximal end engaging portions 12e and 13e are preferable as compared with the conventional case. In addition, it contributes to the proof stress (permissible proof stress, ultimate proof stress) of the joint structure, and the proof stress as the structural member A1 and A2 is improved. Therefore, reinforcement measures are suitably given to structure 10 by providing member A1, A2 for structure reinforcement of this embodiment, and reinforcement structure B of a structure.

  Therefore, in the structural member reinforcing members A1 and A2 of the present embodiment, the joint members 12 and 13 have the concave portions 5 (5a) on the distal end engaging portions 12d and 13d side and the concave portions on the proximal end engaging portions 12e and 13e side The projection 4 (4a) on the proximal end engaging portion 12e and 13e side is made larger than the projection 5 (5b) and is formed to be larger than the projection 4 (4b) on the tip end engaging portion 12d and 13d side Therefore, even if a very large tensile force R acts to cause a warping deformation S on the joint members 12 and 13, the pair of joint members 12 and 13 is engaged by the meshing of the large convex portion 4 and the large concave portion 5. The engagement states of the distal end engaging portions 12d and 13d and the proximal end engaging portions 12e and 13e can be held.

  As a result, not only the concavo-convex portions 12a and 13a in the intermediate portion of the pair of joint members 12 and 13 engaged with each other, but also the concavo-convex portions 12a and 12a on the distal end engaging portions 12d and 13d side and the proximal end engaging portions 12e and 13e side Can also receive the tensile force R.

  Therefore, the convex portions 4 and the concave portions 5 on the distal end engaging portions 12d and 13d side and the proximal end engaging portions 12e and 13e side can be surely contributed to the resistance of the joint structure, compared with the conventional structure. It becomes possible to improve the proof stress as reinforcement members A1 and A2. That is, it becomes possible to reinforce structure 10 more suitably.

  Furthermore, in the structure reinforcing members A1 and A2 of the present embodiment, the respective engaging members are engaged when the adjacent structure reinforcing members A1 and A2 are pulled in the direction of the proximal end and the distal end of the joint members 12 and 13. The angle α between the joint surface 14 and the reference surface P is 90 °> α ≧ 45 °, and the angle β between the engagement surface 15 facing the engagement surface 14 and the reference surface P is α ≧ By setting it as β, the engagement between the engagement surfaces 14 and 15 of the joint members 12 and 13 when the tensile force R acts in the direction in which the reinforcing plates 1 of the adjacent structural reinforcing members A1 and A2 separate from each other It becomes strong and the joint strength of joint members 12 and 13 improves. This makes it possible to reinforce the structure 10 more suitably.

  As mentioned above, although one Embodiment of the member for structure reinforcement which concerns on this invention was described, this invention is not limited to said one embodiment, It can change suitably in the range which does not deviate from the meaning.

  For example, in the present embodiment, the structure 10 to be reinforced has been described as a reinforced concrete pillar, but it is a pillar member other than a reinforced concrete pillar, such as a steel frame pillar, a steel pipe pillar, or a filled concrete steel pipe pillar In addition, the structure according to the present invention may be a horizontal member such as a truss beam, a beam member such as a diagonal member, or the like other than the column member. Furthermore, it is not necessary to limit the cross-sectional shape to a rectangle (square) for structures such as columns and beams.

  In the present embodiment, the structural reinforcing member according to the present invention is a member applied to a steel plate winding method, and the reinforcing plate 1 is described as a steel plate, but the present invention relates to the present invention. In addition to the steel plate, the reinforcing plate may be a reinforcing material such as a stainless steel plate, a duralmin plate, an aluminum plate, a glass fiber, etc. if it can be installed to surround the structure 10 to obtain a reinforcing effect. Other materials such as fiber reinforced plastic (FRP) may be used.

  Although the joint members 12 and 13 are welded to the reinforcing plate 1 and integrally provided, the joint members 12 and 13 may be attached to the reinforcing plate 1 using other joining means such as bolt bonding. Of course it does not matter.
