Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic-resistant pull-out reinforcing metal member capable of preventing the pull-out of beams and columns due to an earthquake and easily performing seismic-proof reinforcement.

[0002]

2. Description of the Related Art The wooden frame construction method draws on the flow of traditional Japanese wooden construction, and is structurally based on frame members such as columns and beams. The joints of columns and beams are mainly joined by mortise processing, and the braces are joined by nails.
On the other hand, there are many earthquakes in Japan, and in the case of a particularly large earthquake, a house may be collapsed by the pillar material standing upright coming off from the beam material or the foundation supporting it.

In order to prevent the columns from coming off, various reinforcing metal parts have been devised. As shown in FIG.
-256700 discloses that the connector 81 is a fastener 8
4, a back surface member 86 attached to the first building structure member 82, attached to the first building structure member 82, a first side surface member 87 connected to the back surface member 86, and first and second anchor receiving members 89, 90. Both the first and second anchor receiving members 89, 90 extend laterally between the first and second side members 87, 88 and both the first and second anchor receiving members 89, 90 are first and second. Connected to the side members 87, 88 of the first and second anchor receiving members 89, 90 to attach the connector 81 to the second building structure member 83 between the first and second anchor receiving members 89, 90. So that there is a space therethrough to receive the anchor member 85. In this way, the first building structure member 82
Can be firmly fixed to the building structure member 83.

[0004]

However, the conventional connector 81, which fixes the first building structure member 82 to the second building structure member 83 via the anchor member 85, has already been completed. There is a problem that it cannot be used in houses. Further, it is not possible to prevent columns from coming off by joining columns and beams. Then, the subject which this invention tends to solve is providing a seismic-resistant pull-out reinforcement metal article which can be used also for the completed house and can be reinforced reliably in a short period of time.

[0005]

In order to solve the above-mentioned problems, the seismic-resistant pull-out reinforcing metal article of the present invention is provided with a first elongated member arranged substantially vertically and directly or through another member. In an earthquake-proof reinforcing metal fitting that connects the connected second elongate member, is fixed to a side surface of the first elongate member,
A first flat plate member having a first vertical hole portion, and a first flat plate member arranged on the same plane or a plane substantially orthogonal to the first flat plate member and fixed to a side surface of the second elongated member. ,
A second flat plate member having a second vertical hole portion arranged substantially on the same axis as the first vertical hole portion of the first flat plate member; the first vertical hole portion; It has a rod-shaped connecting member that is inserted into the second vertical hole and connects the first flat plate member and the second flat plate member in a loosely fitted state. In the present invention, since the first and second flat plate members are arranged on the same plane, they can be attached to the side surfaces of the existing first and second elongated members in a short time. Further, since the connecting member is connected in a loosely fitted state through the first vertical hole portion and the second vertical hole portion of the first and second flat plate members, other than the pulling-out direction of the first and second elongated members. It is possible to release the shearing force and bending stress applied to and absorb the rattling that occurs during a long period after construction.

The base portion of the first flat plate member is attached to the first elongated member, and the tip portion thereof is projected laterally from one end of the side surface of the first elongated member. It is also possible to provide one vertical hole at the tip. With this configuration, the second vertical hole portion is provided.
Of the first elongated member can be fixed at a position slightly away from the longitudinal end of the first elongated member, and the second elongated member is disposed so as to intersect at the end of the first elongated member. Even if it is attached, it can be attached easily and surely.

It is also possible to form the first flat plate member in a line-symmetrical shape with the center line arranged in the lateral direction. With such a configuration, the attachment level is the same even when the protruding direction of the first flat plate member is different.

It is also possible to form the base of the first flat plate member to be narrower than half the width of the mounting surface of the first elongated member. With this configuration, two seismic resistant pull-out reinforcing metal fittings can be attached to the same mounting surface, so that the reinforcing strength is doubled.

Further, the seismic resistant pull-out reinforcing metal article of the present invention is
An earthquake-resistant pull-out reinforcing metal member for connecting a foundation of a building and a foundation provided on the foundation, which is fixed to a side surface of the foundation and has an upper flat plate member having a first vertical hole portion, and the upper flat plate member. And a lower flat plate member that is disposed on substantially the same plane and is fixed to the side surface of the foundation and that includes a second vertical hole portion, and the first vertical hole portion and the second vertical hole portion. It has a rod-shaped connecting member that is inserted and connects the upper flat plate member and the lower flat plate member in a loosely fitted state.
With this configuration, the foundation, the base and the pillar can be reliably connected.

Further, two bases are arranged so as to intersect the base,
It is also possible to dispose a pillar above the intersection of the bases and provide a cutout portion that engages with one of the bases in the upper flat plate member so as to be fixed to the other base and the pillars. Since it has the notch, the upper flat plate member can be easily positioned.

It is also possible to form a connecting member mounting hole in the upper flat plate member for fixing the lower end portion of the braces arranged at the corner between the base and the pillar. With such a configuration, it is possible to simultaneously reinforce the foundation, the foundation, the pillar, and the brace (bracing) with one member.

Further, the connecting member may be composed of a bolt and a nut screwed with the bolt. With such a configuration, the upper flat plate member and the lower flat plate member can be reliably connected, and it is also possible to adjust the looseness and re-fasten.
