Description

  The present invention relates to a metal fitting for reinforcing a house from an outer wall.

  Conventionally, seismic reinforcement plates have been known to reinforce existing houses. This seismic reinforcement plate connects the foundation of the house with the pillars and foundations, and prevents mortises and the like in the event of an earthquake. Since such a conventional seismic reinforcing plate must be attached to a pillar and base of a house, the seismic reinforcing plate is attached to the pillar and base from the surface of the outer wall with a lag screw or the like.

On the other hand, as a conventional house, one using siding as an outer wall is known. This siding is made of plate-like lightweight foamed concrete, etc., and covers the outer surface of the house. A vertical or horizontal trunk edge is attached to the wall surface of the house by nailing, etc. It is attached to the outer periphery of the house.
Moreover, this siding is used as an outer wall for renovation of existing houses as well as newly built houses. In this case, the outer wall of an existing house is attached to a trunk edge, and a siding is attached to the trunk edge to form the outer wall of the house.
When siding is used on the outer wall as described above, if a conventional seismic reinforcing plate is used, it is necessary to provide it outside the siding or to cut off a part of the siding and attach it.

  However, one of the main reasons for using siding on the outer wall is to improve the appearance of the outer wall. However, when the seismic reinforcement plate is exposed, the effect of improving the appearance is greatly reduced. In addition, when part of the siding is cut off, the aesthetic appearance is impaired, and the construction becomes complicated and the cost is increased.

  The present invention aims to improve the reinforcing plate. More specifically, in order to eliminate the inconvenience, the appearance is impaired when performing seismic reinforcement when performing reforming by siding or when constructing a house using siding on the outer wall. It is an object of the present invention to provide a reinforcing plate that is easy to mount.

  In order to achieve the above object, the reinforcing plate of the present invention is a reinforcing plate that reinforces a house provided with a siding that is fixed to a wall surface via a fixture and is mounted with a predetermined distance from the wall surface, It is installed within a predetermined interval between the wall surface and the siding, and is fixed over a plurality of wooden building materials in the vicinity of a connecting portion between the plurality of wooden building materials, and the connecting portion is strengthened with a sleeve.

  Since the reinforcing plate of the present invention is installed in the space between the wall surface of the house and the siding, the reinforcing plate is housed inside the siding and cannot be seen from the outside. Thereby, even if it is a case where siding is used at the time of renovation, or it is a case where siding is used at the time of new construction of a house, it is possible to perform earthquake-proof reinforcement of a house without impairing the appearance. In addition, the reinforcing plate of the present invention is fixed in the vicinity of a joining point of a plurality of wooden building materials, and reinforces the joining of these wooden building materials. For example, by reinforcing the joining between the foundation and the pillar, So-called mortise removal can be prevented.

  In the reinforcing plate of the present invention, it is provided with a buffer part that absorbs the impact when the impact is applied to the plurality of wooden building materials in a direction away from each other, provided in the vicinity of the joining position of the wooden building materials. preferable. When vibration is applied to a house due to an earthquake or the like, there is a case where forces for separating the wooden building materials are applied to the wooden building materials at the connecting points of the plurality of wooden building materials. In such a case, separation between the wooden building materials is allowed to some extent by the buffer portion, so that vibration applied to the attachment location of the reinforcing plate is mitigated. As a result, even if there is a large amount of traffic such as a large truck on a nearby road, and the vibration is often applied to the house, the vibration is buffered by the buffering portion, so that the mounting portion of the reinforcing plate is prevented from being damaged. can do.

  The reinforcing plate of the present invention may be composed of a pair of hard plates disposed on the front and back sides and an elastic member fixed between the pair of hard plates. In this way, when a hard plate such as an iron plate or carbon resin is used on the front and back, and an elastic member such as rubber is fixed therebetween, when the reinforcing plate is attached by a fastening member such as a wood screw, vibration is applied to the house Even so, vibration is absorbed by the elasticity of the elastic member. Further, in the reinforcing plate of the present invention, a fastening member having a fastening hole penetrating the front and back, a flange portion having a diameter larger than that of the fastening hole, and a rod-like fastening portion inserted into the fastening hole, and the flange It is preferable to include a bush made of an elastic member interposed between the portion and the reinforcing plate and between the fastening hole and the fastening portion.

  In this way, by providing the bush at the mounting portion of the reinforcing plate, even if vibration is applied to the house, it is buffered by the bush. Therefore, vibration is hardly transmitted to the fastening member. Looseness and damage are prevented. Moreover, since the said collar part is provided in the said fastening member, since a reinforcement board is attached to the said wall surface via the said bush by the said collar part, a reinforcement board does not remove | deviate from a wall surface.

  Further, the reinforcing plate of the present invention is installed in an orthogonal portion between a vertical building material extending in the vertical direction and a horizontal building material extending horizontally in either one of the left and right sides of the vertical building material, and penetrates the front and back sides. A first attachment portion that has a first fastening hole and is attached to either the vertical building material or the horizontal building material via the first fastening hole by a fastening member, and a length substantially the same as the first attachment portion A second fastening hole that is formed on the front and back and has a second fastening hole that is attached to the other building material via the second fastening hole by a fastening member, and a second mounting part that is orthogonal to the first mounting part, The distance from the end of the first mounting portion to the first fastening hole and the distance from the end of the second mounting portion to the second fastening hole are different from each other by at least the diameter of the fastening member. Is preferred.

  For example, when it is necessary to attach reinforcing plates to both sides of a corner of a house, if the fastening members are screwed or driven into the vertical building material from both sides, the fastening members may interfere with each other. In the reinforcing plate of the present invention, in such a case, the first attachment portion may be attached to the vertical building material on one surface and the second attachment portion may be attached to the vertical building material on the other surface. Thereby, since the 1st fastening hole and the 2nd fastening hole are provided in the position which is more than the diameter of a fastening member, the fastening members of both metal fittings do not interfere.

  Moreover, in the reinforcing plate of this invention, it is preferable to provide the detour part which avoids the said fixing tool when the said fixing tool is fixed to the said wooden building material. When the detour portion is provided, the fixture can be attached to the wooden building material, so that the siding can be attached to the wall surface in the same manner as the conventional siding attachment.

  Or the reinforcement board of this invention WHEREIN: You may provide the mounting part which mounts the said fixing tool. By attaching the fixing tool to the reinforcing plate itself, for example, by attaching the fixing tool to the reinforcing plate in advance, the siding can be mounted simply by attaching the reinforcing plate at the work site.

  The housing reinforced with the reinforcing plate of the present invention is covered with the siding 4 so that the appearance is the same as that of the unreinforced housing. On the other hand, when an earthquake occurs, a so-called “tenon removal” in which, for example, a “tenon” (not shown) provided at the tip of the pillar 3 is removed from a “morte” provided in the base 2 by a reinforcing plate. Can be prevented. Moreover, the metal fitting 8 for attaching the siding is often different for each manufacturer, but according to the reinforcing plate of the present invention, metal fittings of many manufacturers can be attached.

In this case, it is preferable to provide a plurality of screw holes in the reinforcing plate 31 in advance so that the metal fitting 8 can be attached without processing the reinforcing plate 31 at the work site.

  Next, a reinforcing plate 33 according to another embodiment of the present invention will be described with reference to FIG. As shown in FIG. 6, the lower portion of the reinforcing plate 33 is the same as that of the second embodiment except that the reinforcing plate 33 extends upward from the upper portion around the metal fitting 8. By providing the detour portion 6 that detours the metal fitting 8 in this way, the house can be reinforced without being limited by the width of the siding 4.

  Further, the shape of the reinforcing plate is not limited to that disclosed in the above embodiment, and can be various shapes as shown in FIG. For example, as shown to Fig.7 (a), you may make it further reinforce the side part of the reinforcement board 1 of 1st Embodiment. Moreover, as shown in FIG.7 (b), the reinforcement board 1 of 1st Embodiment is made into a curve shape as a whole, Furthermore, the buffer part 32 which bent to the waveform by side view was provided in the approximate center part. Also good.

  Alternatively, as shown in FIG. 7 (c), the wooden building materials in four directions may be reinforced at the positions where the beams 34 are coupled from the left and right of the column 3. Further, as shown in FIG. 7D, the corners of the house may be reinforced by combining two reinforcing plates 21 of the second embodiment. In this case, it is preferable to shift the position of the fastening hole as in the second embodiment.

  Further, as shown in FIG. 7E, a hard plate 35 such as an iron plate may be used on the front and back of the reinforcing plate, and an elastic member 36 such as a rubber plate may be sandwiched between them. When the hard plate 35 is sandwiched between the elastic members 36 in this manner and fixed with the wood screws 10, the hard plate 35 is fixed to the wooden building material via the elastic members 36. Therefore, even when vibration is applied to the house, it is absorbed by the elastic member 36 and the burden on the joint portion between the wood screw 10 and the reinforcing plate is reduced. As the hard plate 35, a carbon resin or the like can be used in addition to an iron plate, and as the elastic member 36, a synthetic resin having elasticity can be used in addition to rubber.

  In each of the above embodiments, the reinforcing plate is formed of a metal plate. However, the present invention is not limited to this, and a synthetic resin such as carbon resin or FRP may be used. Moreover, although the wood screw 10 is used as a fastening member, not only this but a nail, an implantation bolt, etc. may be used.

Hereinafter, an embodiment will be described with reference to FIG. 1 of the accompanying drawings. FIG. 1 is an example in which the reinforcing plate of the first embodiment is attached across a base and a pillar. As shown in FIG. 1, the reinforcing plate 1 is attached across the two members to the orthogonal part of the base 2 and the pillar 3 of the house. In the house reinforced by the reinforcing plate, these reinforcing plates are siding 4. Because it is covered, the appearance is the same as an unreinforced house, but in the event of an earthquake, a mortise (not shown), for example, provided at the tip of the pillar 3 by a reinforcing plate 2 can be prevented from coming out from the “mortise” provided in the mortar 2.
