Hereinafter, the reinforcing tool and building of an embodiment are explained in detail with reference to drawings.
FIG. 1 is an exploded perspective view of a reinforcing tool according to an embodiment.

As shown in FIG. 1, the reinforcing tool 1 includes a pair of brackets 2, 2, a mounting shaft 4, and a rod-like body 5. Examples of the constituent material of the reinforcing tool 1 include metals such as stainless steel, resins, and the like.
The bracket 2 has a substantially U shape, and is fixed to an attachment surface such as a column 10 via an attachment (other member) B. The fixture B is, for example, a screw.
The mounting shaft 4 is fixed to each bracket 2 via an internal push nut 3 so as to be rotatable.

  The rod-like body 5 is stretched between the brackets 2 by screwing male screw portions 5 a, 5 a with reverse screws at both ends into screw holes 4 a formed so as to penetrate perpendicularly to the axial direction of the mounting shaft 4.

  Each bracket 2 is formed by pressing a steel plate having a predetermined thickness into a substantially U shape by press forming. Each bracket 2 has a large and small R surface shape at its corners in order to give a design appearance to both side plates 2A. A plurality of mounting holes 2 a for inserting the mounting portion B are formed in the back plate 2 </ b> B of each bracket 2. Moreover, the large-diameter hole 2b for inserting the attachment shaft 4 rotatably is formed in the both side plates 2A of each bracket 2.

A mounting hole 2a of the mounting tool B is formed in the extension portion 2B1 of the back plate 2B extended in the vertical direction (or the front-rear direction) from the shortest position of the shaft center on which the mounting shaft 4 is mounted. The extension 2B1 has a shape extending from the position of the side plates 2A, 2A to which the mounting shaft 4 of the back plate 2B is attached to one of the shortest positions in the vertical direction (or the front-rear direction).
The extension 2B1 may be formed to have substantially the same length in both the upper and lower (or front and rear) directions of the mounting portion of the mounting shaft 4.

  The mounting shaft 4 is obtained by cutting a large-diameter round steel having an outer diameter substantially equal to the inner diameter of the mounting hole 2 a to be slightly larger than the width of the bracket 2. Grooves 4 b for fitting the push nut 3 are threaded on the outer periphery of both ends of the mounting shaft 4. By fitting the push nut 3 into the groove 4b at the side protruding end of the bracket 2, the mounting shaft 4 is rotatably supported by the bracket 2 while being prevented from being pulled out.

The rod-shaped body 5 is composed of a round steel rod having a small diameter such as free-cutting stainless steel. On both sides of the rod-like body 5, male screw portions 5a are provided by reverse screws. The male screw portions 5a and 5a have a pitch opposite to each other, and the screw hole 4a of the mounting shaft 4 also has a screw hole shape with a reverse pitch according to the male screw portions 5a and 5a. The rod-shaped body 5 and the mounting shaft 4 are screwed to the both mounting shafts 4 so as to be tightened and loosened according to the rotation direction of the rod-shaped body 5.
The rod-shaped body 5 may be formed of a square bar or a flat plate bar except for the male screw portions 5a at both ends.
FIG. 2: is the front view which shows the state which attached the reinforcement tool between pillars, and sectional drawing in the AA line.
FIG. 2A shows a case where a pair of a pair of reinforcing tools 1 is mounted so as to cross over the opposing surfaces of the columns 10 in a pair of housing shaft groups.

  The lower horizontal member 11 constitutes a base for erecting the pillar 10. The upper horizontal member 12 has a shaft structure composed of horizontal members such as a girder installed on the upper part of a column or a torso.

By attaching the upper and lower brackets 2 so as to be positioned on the other column 10, the rod-like bodies 5 are arranged so as to intersect with each other in an X shape at a substantially central position in the height direction between the columns 10.
In addition, you may make it fix the reinforcement tool 1 to the pillar 10 from on a finishing material.

  In particular, as shown in FIG. 2 (b), the screw holes 4 a of the mounting shafts 4 of the pair of left and right reinforcing tools 1 are formed to be shifted from the center in the axial direction of the mounting shaft 4 to the left and right. As a result, even if the mounting positions of the left and right brackets 2 are mounted at the same position such as the column center of the column 10, the crossing positions of the rod-shaped bodies 5 cross in an X shape without interfering with each other. In this state, by screwing both ends of each rod-shaped body 5 to the mounting shaft 4 and rotating in the tightening direction, each rod-shaped body 5 is stretched between the columns 10 with a necessary tension being introduced, An X-shaped bracing is formed between the columns 10 as an earthquake-proof reinforcement structure.

  When the reinforcing tool 1 is attached to the column 10, the rod-shaped body 5 is rotated in an inclined direction so that the mounting hole 2 a formed in the extension 2 </ b> B <b> 1 of one bracket 2 is not covered by the rod-shaped body 5. In this state, the fixture B is screwed and fixed to the column 10. In this state, the other bracket 2 is rotated in the direction of the opposite pillar 10 and joined so as to be along the attachment surface of the pillar 10, and the bracket 2 is attached and fixed by the fixture B. Thereafter, the rod-shaped body 5 is rotated in the forward and reverse directions so that the brackets 2 and 2 are pressed against the opposing surfaces of the columns 10 and 10 so as to apply tension to the rod-shaped body 5. .

Both brackets 2, 2 have an extension 2 </ b> B <b> 1 of the bracket 2 attached to the mounting shaft 4, so that when the reinforcing tool 1 is attached between the columns 10, 10 in an obliquely up and down direction, the attachment B can be easily inserted and fixed. 4 is attached so as to face outward.
Next, various structural examples using the above-described reinforcing tool 1 will be described.
FIG. 3 is a front view for explaining a modification in a state where the reinforcing tool is attached to the building as a brace.

  First, FIG. 3A is a diagram showing the attachment range of each reinforcing tool 1 to the column 10. If the total height from the base 11 of the pillar 10 to the horizontal member 12 is H, the distance between the upper and lower brackets 2 is fixed, for example, within a range of 70% of the total height H, and the rods 5 are crossed in the X shape. It is stretched between the pillars 10. Thereby, the earthquake-proof reinforcement structure by X-shaped bracing is completed. The attachment range of each reinforcing tool 1 to the column 10 may be substantially the same as the range of the total height H or a slightly shorter range.

  In FIG. 3 (a), an inter-column 14 is erected between the columns 10, and the lower position and the upper position between the columns 10 are openings partitioned by a window base 15 and a lintel 16 that are horizontally disposed respectively. A portion 17 is formed. A fitting such as a window frame sash 18 is attached to the opening 17. As shown in the figure, the window frame sash 18 can be a snap-in type, a rotation-opening type, a raising-and-lowering type, or a combination of these when the opening size of the column 10 is small.

  In the above structure, after the shaft assembly work, the window frame sash 18 is left and covered with the inner and outer wall portions, and the bar-shaped body 5 is formed in the X shape on the window surface constituted by the window frame sash 18. It will be exposed in a cross shape. Since the rod-shaped body 5 has a small diameter, it can sufficiently ensure a view through the window surface, and is made of stainless steel or the like, so that it can create a novel design appearance that has never existed before.

  Next, FIG. 3 (b) shows a case where, for example, in the new construction or renovation of a building, an opening is formed in a large portion between the pillars 10 and seismic reinforcement is also performed in order to ensure the sunlight. FIG.

  The hatched portion shown in FIG. 3B shows a portion covered with the inner and outer wall surfaces. The same applies to FIGS. 3C and 3D. In FIG. 3 (b), an opening 19 is formed in a portion partitioned by the lower horizontal member 11 serving as a base between the pillars 10 and the lintel 16, and a pair of reinforcing tools 1 are disposed between the openings 19. The rod-shaped body 5 is crossed in an X shape inside the portion 19.

  Here, the width of the bracket 2 is narrower than the width of the side surface of the column 10. Therefore, for example, even when the reinforcing tool 1 is arranged inside the building in the column 10, the window frame sash can be arranged at a place where the reinforcing tool 1 on the side surface of the column 10 is not set (outside the column 10). . As described above, when the opening width between the pillars 10 is narrow, it is possible to use a sash that fits in, a rotation opening type, a raising / lowering type, or a combination thereof.

  Next, FIG. 3 (c) shows that an opening 20 serving as a skylight is formed on the lintel 16 that is horizontally mounted on the upper part between the pillars 10 in order to secure the sunlight in a new construction or reconstruction work of a building. It is a figure which shows the case where earthquake-proof reinforcement is also performed together. A pair of reinforcements 1 is disposed on each pillar 10 while a pillar 14 is erected on the lower part of the lintel 16 between the pillars 10. FIG.3 (c) has shown the case where the rod-shaped body 5 with which the reinforcement tool 1 is provided is stretched between both the pillars 10 in the state which cross | intersected X shape, and this part is covered with the interior and exterior wall surface.

  Further, in FIG. 3 (d), contrary to FIG. 3 (c), an opening portion 21 serving as a ground window portion is provided between the lower portion of the window base 15 and the base 11 which are laid across the lower portion between the columns 10. It is a figure which shows the case where seismic reinforcement is also performed together. In FIG. 3 (d), a pillar 14 is erected on the upper part of the window 15 between the pillars 10. In addition, a pair of reinforcing tools 1 is disposed on each column 10 in the upper part of the window base 15. FIG. 3D shows a case where the rod-like body 5 included in the reinforcing tool 1 is stretched between both pillars 10 in a state of crossing in an X shape, and this portion is covered with the inner and outer wall surfaces.

In addition, the pattern which forms an opening part is not limited to the thing of Fig.3 (a)-FIG.3 (d). For example, it is possible to provide an opening on the entire surface surrounded by the column 10, the lower horizontal member 11, and the upper horizontal member 12.
Moreover, the opening part 19 shown in FIG.3 (b) can also be provided in the part partitioned off by the upper horizontal member 12 and the lintel 16. FIG.
Further, in order to increase the strength of the bearing wall, it is preferable to provide the studs 14, but the studs 14 can be omitted.

Also, the number of openings can be two or more. For example, the positions of the openings shown in FIGS. 3C and 3D can be combined to form two openings at the top and bottom.
FIG. 4 is a front view for explaining various uses of the reinforcing tool.

  Fig.4 (a) shows the example which provided the reinforcement tool 1 in the vertical direction or the horizontal direction, and used it as the tension rod. One or a plurality of reinforcing tools 1 may be provided in the vertical direction, one or a plurality in the horizontal direction, or in the vertical and horizontal directions, depending on the purpose of reforming or the like.

  When the reinforcing tool 1 is provided in the vertical direction or the horizontal direction, the height of the bracket 2 may be increased so that the distance between the end of the rod-like body 5 and the inner wall surface of the bracket 2 is increased. .

FIG. 4B shows an example in which the reinforcing structure 1 of the present invention is adapted to a beam-to-beam or a right-angle intersection between a base and a base so that the reinforcing tool 1 functions as a fire striking material. Indicates.
Furthermore, as shown in FIG.4 (c), the reinforcement tool 1 can also be used as a suspension material of the collar 40 (or shelf).
FIG. 5 is a partial perspective view showing a state in which the reinforcing tool is fixed to the vertical frame of the window frame in the vicinity of the sliding door sash.

  In FIG. 5, the window frame sash 31 is assembled | attached to the outer side part of the window frame 30 comprised by the horizontal rod 30a and the vertical rod 30b attached to a shaft assembly structure. A sliding door sash 33 having a window glass 32 fixed inside is attached to the window frame sash 31 so as to be laterally movable.

  There is a sufficient width on the inner side of the window frame 30. On the other hand, since the width W of the bracket 2 of the reinforcing tool 1 is small, the reinforcing tool 1 can be attached to the vertical rod 30b of the window frame 30. Specifically, the pair of reinforcing tools 1 can be fixed to both sides of the vertical hook, and the rod-like body 5 can be stretched in a state of crossing in an X shape at the center. In this embodiment, since the seismic reinforcement can be performed without changing the frame such as the frame of the building and the interior and exterior of the frame, the seismic construction of the existing building can be simplified.

Further, the mounting position of the bracket 2 in the vertical rod 30b is not limited to the illustrated one, and for example, the bracket 2 may be mounted so that the end of the bracket 2 is in contact with the window frame sash 31. Moreover, you may attach so that the edge part of the bracket 2 may correspond to the edge part of the near side of the vertical hook 30b.
FIG. 6 is a cross-sectional view showing a state in which the reinforcing tool is attached to the column.

Some pillars 10 have a plaster board or a decorative sheet attached inside the pillars 10. For example, as shown in FIG. 6B, when the bracket 2 is attached to a gypsum board 22 provided between the pillars 10, the length of the fixture B is set longer by the thickness of the gypsum board 22. . Thereby, the bracket 2 can be safely attached. Of course, as shown in FIG. 6A, the bracket 2 can be directly attached to the outer surface of the column 10.
FIG. 7 is a partial perspective view showing another embodiment of the rod-shaped body.
FIG. 7 shows an example of a device for giving tension to the rod-like body 5.

  First, FIG. 7A shows an example in which square or flat engaging portions 5b are formed on both sides of an arbitrary outer peripheral portion of the cylindrical rod-like body 5. FIG. By tightening and tightening a tightening tool L such as a wrench in the engaging portion 5b, it is possible to tighten and loosen with a strong force. Needless to say, a part or the whole of the rod-like body 5 excluding the male screw portion 5a may be a square shape such as a quadrangle or a hexagon.

  Moreover, in FIG.7 (b), the rod-shaped body 5 is divided into 2 and the external thread part 5c which consists of a reverse screw is formed in the divided | segmented edge part, respectively. By connecting the rod-like bodies 5 so that they can be tightened and loosened by means of a cylindrical turnbuckle tool TB formed on both sides with female thread portions of a pitch suitable for each male screw portion 5c, the amount of adjustment at the time of tightening is increased. Yes.

In FIG. 7B, the outer periphery of the turnbuckle tool TB is cylindrical, but it can be tensioned by strong tightening and loosening with the tightening tool L by partially flattening.
In any case, these devised portions can be prevented from affecting the tightening / loosening operability by avoiding the position where the operation portion crosses the X-shape of the rod-like bodies 5.

In addition, in this Embodiment, the bracing as a tensile strength material between vertical members, such as a column, was formed by hanging the rod-shaped body 5 of the reinforcing tool 1 in an X shape, but only one piece is obliquely wound. But it functions as a brace. Moreover, as above-mentioned, it can be spanned in parallel between vertical members, or it can be spanned in parallel between horizontal members, and it can also function as a horizontal or vertical tension rod. Moreover, as above-mentioned, it can also be used as a burning material or as a suspension material.
Next, the effect | action of the reinforcement tool 1 when a horizontal force is added to the building which attached the reinforcement tool 1 is demonstrated.
FIGS. 8-10 is a figure explaining the effect | action of a reinforcement tool when a horizontal force is added to the building which attached the reinforcement tool.

  The bearing wall 50 includes columns 10 and 10, a lower horizontal member 11, an upper horizontal member 12, and the reinforcing tool 1. When a horizontal force (force) from the left and right is applied to the load bearing wall 50, the bracket 2 in the reinforcing tool 1 is configured to bear a moment (rotation force). For this reason, the moment concerning the pillar 10 can be reduced. As a result, even if it uses together with the opening parts 17, 19, 20, and 21, damage to the pillar 10 can be reduced. This will be specifically described below.

  As shown in FIG. 8, when a horizontal force from the left side is applied to the bearing wall 50, a moment P <b> 1 is generated in the vicinity of the joint between the column 10 and the reinforcing tool 1 due to the reaction force of the bearing wall 50. When a small amount of applied force is applied to the bearing wall 50, the rod-shaped body 5 of the reinforcing tool 1 expands to some extent. When no additional force is applied, the rod-shaped body 5 expands and contracts and returns to its original state. Thus, according to the load-bearing wall 50, the deformation of the load-bearing wall 50 is suppressed by supporting the distortion of the columns 10 and 10 by the stress.

FIG. 9 shows the bearing wall 50 at the time of small deformation.
When the moment P1 increases and becomes the moment P2 (the moment is equal to or greater than a predetermined amount), the bracket 2 slips downward from the joint portion with the column 10 due to deformation (bending) of the fixture B. Thereby, stress is released to the fixture B and the moment applied to the column 10 is suppressed from increasing. 8 to 10 illustrate a nail as the fixture B. This nail is preferably not hardened. Thereby, since it becomes easy to deform | transform compared with the case where it hardens, it can suppress that a stress is applied to another location and can suppress that the pillar 10 and another location break.

FIG. 10 shows the load-bearing wall 50 during large deformation.
When the moment P2 increases and becomes the moment P3 (the moment is equal to or greater than a predetermined amount), the bracket B further slips from the joint portion with the column 10 by further deforming the fixture B. Further, the rod-like body 5 is also deformed with the horizontal force. Also, at the joint Q between the bracket 2 facing the bracket 2 surrounded by the dotted line in FIG. 10 and the column 10, the fixture B is deformed, and the bracket 2 slips upward from the joint Q with the column 10. Thereby, it can suppress that pillar 10 and other places break.

  In this way, when a small amount of applied force is applied to the load bearing wall 50, the rod-shaped body 5 extends to some extent, thereby stopping the deformation of the load bearing wall 50. However, if the applied force exceeds a certain level, the bracket 2 is slipped by deforming the fixture B, and the moment applied to the column 10 is prevented from increasing. When the applied force is further increased, in addition to the deformation of the fixture B, the rod-shaped body 5 is further deformed, thereby preventing the bracket 2 from slipping greatly and increasing the moment applied to the column 10 and damaging the column 10 and the like. Suppress.

FIG. 11 is a diagram illustrating a comparative example.
FIG. 11A shows a state when the bearing wall 70 is deformed using the brace 60 instead of the reinforcing tool.
When a horizontal force from the left side is applied to the load bearing wall 70 using the brace 60, a rotational force A is generated in the vicinity of the joint between the column 10 and the brace 60 due to the reaction force of the load bearing wall 70. Will occur. As the horizontal force increases, the moment increases, but almost all of this moment is applied to the column 10. As a result, the possibility that the pillar 10 is damaged increases. In addition, when the left force is applied, it is in the direction in which the diagonal line extends because it is a tension bar. For this reason, when a dedicated hardware or the like is used so that the joint portion does not come out, the possibility that the pillar 10 is further damaged increases.

  FIG. 11B shows a state when the load bearing wall 90 using the face material 80 instead of the reinforcing tool is deformed. When a horizontal force from the left side is applied to the load bearing wall 90 using the face material 80, a rotational force A is generated in the vicinity of the joint between the column 10 and the face material 80 due to the reaction force of the load bearing wall 90. A big moment is generated. As the horizontal force increases, the moment increases, but almost all of this moment is applied to the column 10. As a result, the possibility that the pillar 10 is damaged increases.

  On the other hand, as described above, according to the bearing wall 50 using the reinforcing tool 1, the fixture 10 and the rod-shaped body 5 are deformed to suppress a large moment from being generated in the column 10. Suppresses damage such as.

By the way, when the strain of the column 10 is supported by the stress (when the moment is smaller than the moment P2) and when the strain of the column 10 is supported by the deformation of the fixture B (when the moment is the moment P2 or more), the bracket 2 The designer can arbitrarily determine the number by changing the number and arrangement pattern of the fixtures B when attaching to the pillar 10.
In addition to the mounting screws shown in FIG. 1, examples of the mounting tool B include bolts, N nails, CN nails, lag screw bolts, and coach screw bolts.

  An example of the diameter of the mounting screw is 4.5 mm to 6.3 mm. The magnitude | size of the diameter of a volt | bolt is 10-22 mm as an example. As an example, the diameters of the N nails and CN nails are 1.5 mm to 6.65 mm. As an example, the diameter of the lag screw bolt is 18 mm to 25 mm. As an example, the diameter of the coach screw bolt is 6 mm, 9 mm, or 12 mm.

  The length of the mounting screw is 30 mm to 100 mm as an example. The length of the bolt, for example, 120 mm to 210 mm. As an example, the diameter of the N nail and the CN nail is 40 mm to 100 mm. The diameter of the lag screw bolt is 50 mm to 100 mm as an example. As an example, the diameter of the coach screw bolt is 30 to 100 mm.

FIG. 12 is a diagram for explaining an arrangement pattern of fixtures.
FIG. 12A is a diagram for explaining an arrangement pattern of fixtures when the fixture is any one of a screw, a nail, and a coach screw bolt. When the bracket 2 is attached to the column 10 using screws, nails or coach screw bolts, as shown in FIG. 12 (a), one is slightly inclined with respect to the other in the vicinity of the center of the bracket 2. Four mounting holes 2a are opened. Also, two attachment holes 2a are formed in the lower part of the bracket 2 so that one is slightly inclined with respect to the other. Then, the bracket 2 is attached to the column 10 by inserting either a bolt or a lag screw bolt through the mounting hole 2a.

By the way, the reinforcing tool 1 and the face material can be used in combination.
FIG. 16 is a diagram illustrating a combination of a reinforcing tool and a face material.

FIG. 16A is a view showing the face material bearing wall 110 viewed from the outer wall side, and FIG. 16B is a cross-sectional view taken along line BB in FIG. A face material 100 is provided on the face material bearing wall 110 so as to cover the reinforcing tool 1. In this way, by combining the reinforcing tool 1 with the face material 100, it is possible to easily increase the yield strength of the load bearing wall as compared to the load bearing wall using only the face material.
By the way, although the nail was illustrated as the fixture B in FIGS. 8-10, the effect | action of the reinforcement tool 1 at the time of using a volt | bolt as the fixture B is demonstrated below.
FIGS. 17-19 is a figure explaining the effect | action of a reinforcement tool when a horizontal force is added to the building which attached the reinforcement tool. Parts similar to those in FIGS. 8 to 10 are denoted by the same reference numerals.
The bearing wall 120 shown in FIG. 17 fixes the fixture B inserted through the bracket 2 to the column 10 using a washer C and a nut D.
FIG. 18 shows the load-bearing wall 120 during small deformation.
As shown in FIGS. 8 to 10, the load bearing wall 50 using a nail or the like having a narrow diameter as the fixture B deforms the nail to increase the toughness and maintain the yield strength.

  On the other hand, when a fixture B having a large diameter such as a bolt is used as in the load bearing wall 120 shown in FIG. 18, the strength can be maintained by the toughness of the member itself to be joined. That is, as shown in FIG. 18, when the moment P <b> 1 increases to become the moment P <b> 2, the fixture B starts to sink into the column 10. Thereby, the bracket 2 slips downward from the joint portion with the column 10. As a result, stress is released to the fixture B, and an increase in the moment applied to the column 10 is suppressed.

FIG. 19 shows the load-bearing wall 120 during large deformation.
When the moment P2 increases to become the moment P3, in addition to the fitting B further sinking into the column 10, the washer C starts to sink into the column 10. Thereby, the bracket 2 slips further downward from the joint portion with the column 10. Further, the rod-like body 5 is also deformed with the horizontal force.

  As described above, when the fitting B having a large diameter such as a bolt is used as in the case of the load bearing wall 120 shown in FIGS. 17 to 19, the strength can be maintained by the toughness of the member itself to be joined. . The strength can also be maintained by the washer sinking into the wood.

  As mentioned above, although the reinforcement tool and building of this invention were demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part is arbitrary structures which have the same function. Can be substituted. Moreover, other arbitrary structures and processes may be added to the present invention.
