It is being fixed to the fixing | fixed part 40 provided in (corner | corner part).

  The reinforcing member in the present invention is a plate-like metal member 31, 32 made of a plurality of spring steels having a curved shape capable of absorbing a pressing force and a tensile force (extension force) applied to a structural member of a building. Opposite ends of the plurality of plate-shaped metal members are formed so as to face each other and form a space between the plate-shaped metal members. The space portion includes a damper member configured by appropriately combining metal members (metal plates) having different shapes.

Specifically, for example, as shown in FIG. 3, the damper member is a combination of a semicircular metal member 311, an S-shaped metal member 312, and a small semicircular metal member 312, In the space formed between the curved plate-shaped metal members 31 and 32, the fixture 60 (for example, a bolt) is in contact with the plate-shaped metal member at the center of the curved plate-shaped metal members 31 and 32. It is fixed with a nut). Specifically, the semicircular metal member 311, the S-shaped metal member 312, and the small semicircular metal member 313 are formed by overlapping the semicircular shape with the S-shape and the small semicircular shape on the outside. Fixed to. The S-shaped metal member 312 and the small semicircular metal member 313 are combined by attaching a small semicircular metal member in contact with the S-shaped curved portion, and a portion denoted by reference numeral 61 with the S-shaped metal member It is fixed with.
4 is a combination of an S-shaped metal member 312 and a small semi-circular metal member 313, and the damper member is provided between the plate-shaped metal members 31 and 32 having a curved shape. Another mode in which the formed space is filled with the synthetic resin foam molded body 314 is shown. The reinforcing members 30 are fixed by connecting portions 41 provided at both ends thereof by means of the connecting members 301 and fixtures 411 such as bolts and nuts, respectively.

  Plate-like metal members 31 and 32 made of spring steel having a curved shape constituting the reinforcing member 30 used in the present invention are disposed in a space formed between the plate-like metal members with the curved surfaces facing each other. Instead of the semicircular metal member as the damper member, a metal member having a circular cross section can be used in combination with an S-shaped metal member. As the metal member functioning as the damper member, a general steel plate or soft iron that can be plastically deformed is used. The width and thickness of the metal member constituting the damper member are appropriately determined depending on the width and thickness of the metal member made of spring steel, the size of the reinforcing member, and the structure of the building to be applied (steel structure or wooden structure). Selected.

  Further, in the space formed between the plate-like metal members with the curved surfaces of the plate-like metal members 31 and 32 made of spring steel having a curved shape constituting the reinforcing member 30 used in the present invention, In addition to the damper member, a synthetic resin foam molded body can be disposed (FIGS. 2 and 4). By disposing the synthetic resin foam molding in the space between the plate-like metal members 31 and 32, the tensile force extending in the both ends of the reinforcing member, that is, the space formed between the plate-like metal members is narrowed. When a load in the direction is applied, the energy is absorbed, and it has a function of complementing the force against the compressive strength of the damper member.

  The synthetic resin foam molding is disposed in contact with the curved surface in the space between the plate-like metal members, and is fixed to the curved surface with an adhesive, an adhesive tape, or the like as necessary. The synthetic resin foam molding may be disposed (filled) over the entire space so as to surround the damper member. However, when the shape of the damper member is irregular and complicated, for example, FIG. As shown in FIG. 4, it arrange | positions so that the space part except the part in which the said damper member exists may be filled.

  As the synthetic resin foam molded article, for example, a polystyrene resin foam or a polyolefin resin foam can be used. These foams may be either extruded foams or bead foams, and are usually used as molded bodies formed so as to conform to the shape and size of the space.

  The corner part where the adjacent structural member (column member and horizontal member) joins the reinforcing member in the present invention in the space formed between the structural members of the horizontal member such as the pillar member and the base, beam, etc. facing each other When the building is a steel structure, the connecting member 301 with the structural member for disposing over the opposite corner portion from one side is H-shaped, U-shaped in cross section, groove-shaped, plate-shaped Steel material such as a prismatic shape is used. In the case of a wooden structure, a prismatic wooden material is used. Further, the fixing portion 40 of the connecting member 301 provided in the structural member is usually made of steel, and the fixing portion 40 is provided with a fixing hole for the connecting member 301 with the structural member, etc. It is fixed to the frame member or the horizontal member with a fastener such as welding or a bolt and nut.

  The reinforcing member in the reinforcing structure of the present invention is a joint between adjacent structural members in a space formed between structural members facing each other, for example, a space formed by a beam and a base between the column members. For example, from one corner where the column member and the beam are joined to the other corner facing the corner, for example, the corner where the column member and the base are joined, via a connecting member with the structural member. And is attached to a fixing portion provided on the structural member. It is preferable that the connecting member of the reinforcing member with the structural member is attached to the horizontal member side of the fixed portion provided at the joint between the column member of the structural member and the horizontal member. The fixing portion of the connecting member is preferably provided within a range of about 20 cm on the side of the horizontal member from the joint (corner) between the column member of the structural member and the horizontal member. A sufficient reinforcing effect is not exhibited at a position where the position of the fixing portion is too far from the joint portion (corner portion) between the structural members.

  Although not shown, a laminated plate spring can be used for the plate-like metal member made of spring steel of the reinforcing member of the present invention. As the overlap leaf spring, a second leaf spring (sub leaf spring) superposed on the first leaf spring (main leaf spring) is attached in a slidable state. Further, the metal member of the above-described damper member is used by combining a cross-sectional shape of an S-shape and a circular shape, or a semicircular or horseshoe-shaped metal member. Although the metal member can be used alone, it is practically preferable to combine the metal members having different shapes from the viewpoint of giving resistance to deformation of the reinforcing member due to stress (load) such as pressing force.

The reinforcing action of the reinforcing member in the reinforcing structure of the present invention will be described.
When a strong pressing force or tensile force (extension force) is applied to the building due to a horizontal load such as an earthquake or strong wind, the column members of the structural members constituting the building are inclined in the pressing direction or the tensile direction, and the horizontal member (For example, a beam) moves in parallel and shifts. At this time, the space formed between the structural members of the building (between the column members and the horizontal members such as the foundations and beams) is joined from one of the corners where adjacent structural members (column members and the beams and foundations) join. A reinforcing member disposed across the other opposite corner via a connecting member with the structural member acts against a pressing force or a tensile force, and the column member is inclined and laterally It is possible to suppress the movement of the building material and minimize the deformation, distortion and displacement of the building.

  In a space formed between the structural members, a joint portion between adjacent structural members, for example, one corner portion where a column member and a beam are joined, and the other corner portion facing the corner portion, for example, a column member, The reinforcing member of the present invention disposed across the corner where the base joins is provided with the curved plate-like metal member 31 constituting the reinforcing member according to the direction of the pressing force or tensile force applied to the structural member. And 32 in the direction in which the space portion expands, that is, the direction in which both curved portions of the curved plate-shaped metal member protrude outward, or the direction in which the space portion narrows, that is, the direction in which both curved portions extend. However, since the curved plate-shaped metal member is made of spring steel, the energy of the pressing force and the tensile force is absorbed and the expansion or narrowing of the space between the plate-shaped metal members is suppressed.

  Furthermore, the reinforcing member in the present invention is provided with a damper member configured by combining different shaped metal members in the space between the curved shaped plate metal members, and the damper member is provided with the curved plate. In cooperation with the metal member, an action of suppressing the expansion and / or narrowing of the space is added. That is, the metal members having different shapes with respect to the expansion and / or narrowing of the space portion, that is, the semicircular metal member 311 and the S-shaped metal member 312 and the small semicircular metal member 313 are plastically deformed. The function of suppressing the expansion and / or narrowing of the space portion is expressed, and the effect of suppressing the expansion and / or narrowing of the space portion is exhibited. The space formed between the plate-like metal members can be filled with a synthetic resin foam molded body, and the synthetic resin foam molded body has an effect of complementing the function of the damper member.

  Absorbs load energy such as pressing force and tensile force on buildings and buildings due to excessive horizontal loads due to earthquakes and strong winds such as typhoons, attenuates shaking, suppresses deformation of buildings, and returns to the original state Provide a building reinforced structure with earthquake resistance and vibration control with excellent restoring force.
