Here, the anchor bolts and the like exclusively connect and fix the horizontal member of the frame such as the panel forming the wall and the floor member, and the vertical member is not fixed by this.

Therefore, conventionally, a reinforcing metal flat plate has been attached to the side surface of the joint between the vertical member and the floor. However, a metal flat plate has a problem that buckling strength and tensile strength are low.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a joint reinforcing structure capable of reliably reinforcing a joint between a vertical member and a horizontal member.

[0005]

According to a first aspect of the present invention, there is provided a joint reinforcing structure for reinforcing a joint between a wall structure and a lower structure using a joint reinforcing metal. Wherein the joint reinforcing metal is a plate-shaped connecting portion fixed to a side surface of the wall structure and a side surface of the lower structure, and the connecting portion is connected at a right angle to the wall structure. And a reinforcing portion fixed to the side end surface of the body.

According to the first aspect of the present invention, the wall structure and the lower structure are formed by using a joint reinforcing metal having a plate-like connecting portion and a reinforcing portion connected at a right angle to the connecting portion. Can be reliably reinforced.

That is, since the connecting portion is fixed to the side surface of the wall structure and the side surface of the lower structure, the two structures are connected and the joint is reinforced. At this time, since the connecting portion has a plate-like shape, it can be easily fixed to each structure, and can be reliably reinforced with a large contact surface. And since the reinforcement part connected at right angles to a connection part is fixed to the side end surface of a wall part structure, it becomes difficult for a connection part to buckle. Accordingly, the connecting portion is reinforced, and the joint between the wall structure and the lower structure can be reliably reinforced.

[0008] Here, the wall structure means various structures used for constructing a wall of a building. For example, columns, walls, wall panels, and the like are included.

The lower structure refers to a structure located immediately below a wall structure, such as a floor or a ceiling. This includes, for example, semi-bases, trunks, floors, floor panels, and the like.

According to a second aspect of the present invention, in the joint reinforcing structure according to the first aspect, the joint reinforcing metal is connected to the connecting portion and the reinforcing portion, and the wall structure is placed thereon. It has a mounting part.

According to the second aspect of the present invention, since the mounting portion on which the wall structure is mounted is connected to both the connecting portion and the reinforcing portion, the connecting portion is less likely to buckle.

Further, since the mounting position of the joint reinforcing metal is determined by the reinforcing portion and the mounting portion, the mounting operation of the joint reinforcing metal is simplified.

According to a third aspect of the present invention, a pair of wall structures located above and below using a joint reinforcing metal,
A joint reinforcing structure for reinforcing a joint between the pair of wall structures and a transverse member located between the pair of wall structures, wherein the joint reinforcing metal includes a side surface of the pair of wall structures and the transverse structure. A plate-shaped connecting portion fixed to a side surface of the member, a first reinforcing portion connected to the connecting portion at a right angle and fixed to a side end surface of the upper wall structure, and the connecting portion; A second reinforcing portion connected at a right angle and fixed to a side end surface of the lower wall structure.

According to the third aspect of the present invention, by using a joint reinforcing metal having a plate-shaped connecting portion and two reinforcing portions connected at right angles to the connecting portion, a pair of wall structures is used. The joint between the body and the transverse member can be reliably reinforced.

That is, since the connecting portions are fixed to the side surfaces of the pair of wall structures and the side members, the connecting portions are connected to each other, and the joining portions are reinforced. At this time, since the connecting portion has a plate shape, fixing to each structure is easy,
In addition, it is possible to reliably reinforce with a large contact surface. And since the reinforcement part connected at right angles to a connection part is fixed to the side end surface of a wall part structure, it becomes difficult for a connection part to buckle. Accordingly, the connecting portion is reinforced, and the joint between the wall structure and the lower structure can be reliably reinforced. Here, since there is a first reinforcing portion fixed to the upper wall structure and a second reinforcing portion fixed to the lower wall structure, any of the wall structures and the horizontal Buckling hardly occurs even at the joint with the member.

Further, since the connecting portion is fixed to the side surface of the upper wall structure, the side surface of the lower wall structure, and the side surface of the transverse member, two joint reinforcing metal members are used for one joint. The joint can be reinforced at one time. For this reason, cost and labor can be saved by reducing the number of joint reinforcing hardware.

Here, the wall structure means various structures used for constructing a wall of a building. For example, columns, walls, wall panels, and the like are included.

[0018] The horizontal member refers to various members that are laid horizontally. For example, a semi-base, a trunk, a floor, a floor panel, and the like are included.

According to a fourth aspect of the present invention, in the joint reinforcing structure according to the third aspect, the joint reinforcing metal is connected to the connecting portion and the first reinforcing portion, and the upper wall structure is provided. It is characterized in that it has a first mounting portion to be mounted, and a second mounting portion connected to the connecting portion and the second reinforcing portion and on which the horizontal member is mounted.

According to the fourth aspect of the present invention, the first mounting portion on which the upper wall structure is mounted and the second mounting portion on which the horizontal member is mounted are connected to each other by the connecting portion. Since the connection portion is connected to both the reinforcing portion and the reinforcing portion, the connecting portion is more difficult to buckle.

Further, since the mounting position of the joint reinforcing metal is determined by the reinforcing portion and the first and second mounting portions,
The work of mounting the joint reinforcing metal is simplified.

According to a fifth aspect of the present invention, in the joint reinforcing structure according to any one of the first to fourth aspects, the wall structure has a vertical member and a horizontal member assembled in a rectangular shape. It consists of a wall panel having a frame, and the reinforcing portion is fixed to the longitudinal member.

According to the fifth aspect of the present invention, the reinforcing portion is
Because it is fixed to the vertical member that forms the frame of the wall panel,
Not only the joint between the wall panel and the lower structure or the horizontal member, but also the joint between the vertical and horizontal members forming the frame can be reinforced.

That is, in the wall panel having the frame, the cross members are fixed to the lower structure or the like by bolts or the like. Since the vertical members are fixed to the lower structure or the like by the joint reinforcing metal, the positions of the vertical members and the horizontal members are hardly fluctuated, and these joints are not easily broken.
