DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, in a seismic retrofit structure according to an embodiment of the present invention constructed on a Japanese-style wooden house, a sliding door panel 1 is used as an antiseismic reinforcing panel.

First, the configuration of the fusuma panel 1 will be described.

The fusuma panel 1 has vertical frame members 3 made of square steel applied to left and right edges 21 of the structural plywood 2 and is bolted with full screw bolts 31, 31,...

That is, as shown in FIG. 2, pilot holes 22, 22,... Are formed in the left and right edges 21, 21 of the structural plywood 2. In addition, the vertical frame members 3, 3 have internal threads 32, 32,.
... is formed. Then, a full screw bolt 31 having a minus groove formed in the head is screwed into the prepared hole 22 and the female screw 32 by an electric screwdriver to be stopped. Notches 24, 24, 24 are formed in the upper edge portion 23 of the structural plywood 2.
Further, sliding paper is applied to both sides of the structural plywood 2 for finishing. The vertical frame members 3 have a black electrogalvanized finish. The fusuma panel 1 having such a configuration is manufactured in a factory and is carried on site.

The mounting operation of the fusuma panel 1 is performed as follows.

First, as shown in FIG.
Are attached to the groove bottom 102 at predetermined intervals. This attachment is performed by bonding with an adhesive 41 and a nail 4
It is performed by nailing with 2, 42.

Next, as shown in FIG. 4, the sliding door panel 1 is temporarily installed. That is, the fusuma panel 1 is pushed up to the depth of the groove bottom 102 of the Kamoi 101, and the wood piece cotters 4, 4, 4 are engaged with the notches 24, 24, 24. At this time, the lower frame member 5 made of square steel and the lower edge 25 of the sliding door panel 1 and the sill 1
The top end of the sliding door panel 1 is adjusted so that there is no gap above and below the sliding door panel 1 by inserting it from the side instead of the wedge between the groove bottom 104 of FIG. The lower frame member 5 is also subjected to black electrogalvanization. In addition, positioning of a bolt hole 108 (described later) to be opened in the threshold 103 is also performed.

Thereafter, as shown in FIG.
A bolt hole 108 is drilled from above the threshold 103 so as to penetrate the floor plate 105 and the joist material 106. The lower frame member 5 has a bolt hole 5 penetrating through both end portions thereof.
1, 51 are open. Further, female screws 33, 33 are threaded from the lower edge of the vertical frame members 3, 3.
Then, the fusuma panel 1 and the lower frame member 5 are fully inserted, and all the screw bolts 61 and 61 are inserted into the bolt holes 108 from under the floor. It is fixed to the female screw 33 of the frame member 3 by a screw action.
A turnbuckle 6 is provided on the other end of the full screw bolt 61.
The anchor bolts 63, 63 are suspended via the two, 62.

Then, the RC solid foundation 7 is cast under the floor, and the anchor bolts 63 are fixed. Then, the turnbuckles 62 are tightened to fix the feet of the fusuma panel 1 to the foundation 7. A predetermined base 81 is newly installed on the foundation 7, and a reinforcing bundle 8 is provided under the floor immediately below the vertical frame members 3.
2, 82 are fixed. Grooves 83, 8 are provided in reinforcing bundles 82, 82.
3 are formed, and the reinforcing bundles 82, 82 are inserted into the grooves 83, 83 with the full screw bolts 61, 61, turnbuckles 62, 62, and anchor bolts 63, 63 inserted.
Is fixed. Joist hanging material 107, newly installed reinforcing bundle 82,
82, bundle 110 on existing slab stone 109, new foundation 81
The structural plywood 84 is stuck by driving nails 85, 85,.

The upper ends of the vertical frame members 3, 3 and the Kamoi 101
The spacer 43 is fixed between the groove bottoms 102.

Next, the operation will be described.

According to the above-mentioned seismic retrofit structure, the upper and lower sides of the fusuma panel 1 using the structural plywood 2 are placed between the gate 101 and the threshold 103.
And can withstand the seismic shear force of the wooden building by the shear strength of the structural plywood 2.

Further, when the structural plywood 2 tries to fall right and left under the shearing force, the vertical plywood 3, the turnbuckle 62 and the anchor bolt 63 are used.
3 can be suppressed by being tied to the foundation 7.

The vertical frame members 3, 3 and the structural plywood 2 are bolted by full-screw bolts 31, 31,..., And these full-screw bolts 31, 31,. Thereby, not only strength but also toughness can be exhibited during an earthquake.

The fusuma paper is attached to both sides of the structural plywood 2 to form the fusuma panel 1. Therefore, instead of the existing fusuma, if the upper and lower sides of the fusuma panel 1 are attached to the Kamoi 101 and the sill 103, it is like an existing fusuma. Because wooden structures can be seen, wooden buildings do not lose their openness and are easily preserved in their original state.

Left and right edges 21, 21 of the structural plywood 2
Frame material 3, 3 of square steel with black electrogalvanized steel
And are fastened with full screw bolts 31, 31,.... A lower frame member 5, which is also a square steel plated with black electrogalvanized steel, is inserted between the lower edge of the structural plywood 2 and the groove bottom of the sill 103. Thereby, the vertical frame members 3 and 3 and the lower frame member 5 can be made to look like a sliding door edge, and the sliding door panel 1 can be made to look more like a sliding door.

Since the foot of the fusuma panel 1 is fixed to the new foundation 7 via the full screw bolt 61, the turnbuckle 62, and the anchor bolt 63, the fusuma panel 1 is prevented from being pulled out in the event of an earthquake. Fully demonstrates seismic performance.

[0033]

According to the first aspect of the present invention, the original state is preserved as much as possible so that the openness is not impaired as much as possible, and seismic reinforcement of the wooden building by the seismic reinforcement panel is enabled. be able to.

According to the invention described in claim 2, according to claim 1
In addition to the effects similar to those of the invention described in (1), since the sliding door panel looks more like a sliding door, the original state is more easily preserved. In addition, it is possible to further improve the seismic performance by adding tenacity to the seismic retrofitting panel.

According to the invention described in claim 3, according to claim 1
Or in addition to having the same effect as the invention described in claim 2,
In the event of an earthquake, the sliding out of the fusuma panel is prevented, and the anti-seismic performance can be fully exhibited.
