DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic strengthening method, a seismic structure and a seismic fitting for strengthening an earthquake-resistant structure of a wooden house after construction. "Wooden house" in this specification
Means that wooden pillars are used as the main aggregate, and does not matter the material of the outer wall.

[0002]

2. Description of the Related Art In a conventional wooden house, a base wooden pillar placed on a concrete foundation is fixed by bolts projecting upward from the concrete foundation, and a vertical wooden pillar is mounted on the base wooden pillar fixed by the bolt. By constructing pillars and fitting braces appropriately, the framework is completed. In addition, the base wooden pillars installed horizontally, or the base wooden pillars and the vertical wooden pillars vertically built thereon are provided with convex portions and concave portions and are fitted, but they do not provide reinforcement against earthquake. . Therefore, the seismic structure of a traditional wooden house
A rectangular iron plate, an L-shaped iron plate, or the like has been strengthened by being attached to the base wooden pillars and between the base wooden pillars and the vertical wooden pillars.

[0003]

When a large earthquake occurs, such as the Great Hanshin-Awaji Earthquake, horizontal and vertical forces are applied to the base of a wooden house. Thus, a wooden house without bracing is at risk of collapse, even in a modest earthquake. Even in a wooden house with bracing, the vertical force acts in the direction of being pulled out of the concrete foundation, causing the first floor to collapse. Particularly in the case of a large earthquake such as the Great Hanshin-Awaji Earthquake, wooden houses with bracing may cause collapse when the base wooden pillars fixed by bolts on the concrete foundation separate from the concrete foundation. I understood. However, wooden houses built before the Great Hanshin-Awaji Earthquake were not built with sufficient consideration of fixing concrete foundations and foundation wooden pillars.

[0004] In order to solve the above-mentioned problems, the present invention is to fix a concrete base of a wooden house after construction and a base wooden pillar or a vertical wooden pillar built thereon so as to be robust and resistant to earthquakes. It is an object of the present invention to provide a seismic retrofitting method, a seismic structure, and a seismic fitting for a wooden house after construction.

BEST MODE FOR CARRYING OUT THE INVENTION (First invention) In a wooden house, a wooden pillar placed on a concrete foundation is fixed by bolts embedded in the concrete foundation, and the wooden house is vertically perpendicular to the wooden pillar. Wooden pillars have been built, and a frame has been made by inserting braces and the like. The first invention relates to a seismic retrofitting method after the construction at the junction of the concrete foundation, base wooden pillar, and vertical wooden pillar of the wooden house.

In the first step, the outer wall is marked at a predetermined height and width around the vertical wooden pole, and only the outer wall is removed by cutting the marked portion. In this operation, be careful not to damage the internal pillars and vertical pillars when cutting the outer wall. In the second step, nuts whose outer periphery and inside are threaded are driven into the base wooden pillar and the vertical wooden pillar. The nut is aluminum,
It is made of iron, an alloy thereof, or the like in a tapered shape that becomes thinner toward the tip. And
The screw provided on the outer periphery of the nut can bite into the base wooden pole or vertical wooden pole, and at the same time, can absorb a small vibration between the screw and the wood.

In the third step, a bolt embedded in the concrete foundation or a bolt fixed therethrough is provided so as to protrude to the side. The fourth step is a reinforcing and cover receiving plate provided with a mounting hole at a predetermined position,
And a seismic plate having a width and a length capable of fixing the vertical wooden pillar and the base wooden pillar at least partially in a bracing manner is fixed by the nut and the bolt protruding laterally from the concrete foundation. The reinforcing and cover receiving plate serves as a spacer for filling a step between the concrete foundation and the base wooden pillar, a reinforcing role together with the earthquake-resistant plate, and a portion for attaching a cover described later. Further, since the mounting holes provided in the reinforcing and cover receiving plate and the earthquake-resistant plate are opened so as to be aligned with each other, the mounting strength to the concrete foundation and the base wooden pillar is improved.

In a fifth step, a cover is attached to the reinforcing and cover receiving plate. It is preferable that the cover has a shape having a flange on an upper portion and a side portion so that rain or the like does not enter the inside. In the sixth step, post-processing is performed on the cover. For example, by inserting a caulking member into the flange portion of the cover, a process is performed to achieve waterproofness or to make the color of the surface of the cover the same as that of the outer wall.

(Second invention) A second invention is a method of reinforcing a corner portion of a wooden house after construction. That is, a concrete foundation constituting a right-angled portion that is an intersection from two directions, two foundation wooden pillars fixed on the concrete foundation, and a vertical wooden pillar vertically built on the foundation wooden pillar are joined respectively. This method is carried out in the same manner as the first to sixth steps of the first invention. According to the above-mentioned corner part seismic retrofitting method, the wooden house is not collapsed even by a large earthquake because the corner of the wooden house is not pulled out from the concrete foundation.

(Third invention) In a third invention, an opening is provided in a base wooden pillar and a vertical wooden pillar as a sleeve instead of the threaded nut of the first invention or the second invention, and this opening is formed. The cover is inserted through the sleeve, and the reinforcing and cover receiving plate and the earthquake-resistant plate are fixed by bolts and nuts. In the third invention, although the strength is slightly reduced as compared with the threaded nut of the first invention or the second invention, the construction can be performed at low cost.

(Fourth invention) A fourth invention is an earthquake-resistant plate used in a place other than the corner portion, and is used in a portion having relatively low reinforcing strength. Accordingly, the seismic plate of the fourth invention is of the same width up to and including the vertical wooden pillar, the foundation wooden pillar, and the concrete foundation, and cannot be fixed to the brace.

(Fifth invention) The fifth invention relates to an earthquake-resistant structure at a corner of a wooden house after construction. The concrete foundation is provided with upper bolts projecting upward to fix the base wooden pillars horizontally, and side bolts projecting at right and left sides of the concrete foundation on two sides. The base wooden pillar fixed on the concrete foundation is fixed by the upper bolt projecting on the concrete foundation. The vertical wooden pillar is built vertically on the connection of the base wooden pillar. Further, a tapered nut threaded on the outer periphery and inside is screwed into a predetermined position between the base wooden pillar and the vertical wooden pillar.

The reinforcing and cover receiving plate has a thickness substantially equal to the step formed by the concrete foundation and the base wooden pillar, and has a mounting hole at the same position as the nut threaded on the outer periphery and inside. ing. The seismic plate is
It is composed of a wide mounting part extending to the concrete foundation and a narrow mounting part extending to the vertical wooden pole, and has a mounting hole at the same position as the nut and the side bolt. A cover mounting seat is mounted on the reinforcing and cover receiving plate, and a cover that covers the corner is mounted via the cover mounting seat.

Since the earthquake-resistant structure having such a structure is resistant to the force in the pulling-out direction even by a strong earthquake, it does not collapse even in a wooden house after construction. When the step formed by the concrete foundation and the foundation pillar is larger than the thickness of the reinforcing and cover receiving plate, the bolt mounting surface is leveled by replenishing a liner having an appropriate strength. .

(Sixth invention) A sixth invention is an earthquake-resistant structure in a reinforcing portion of a wooden house after construction. The fifth embodiment is different from the fifth embodiment in that, except for the corners, vertical wooden pillars are erected substantially in the middle rather than at the ends of the base wooden pillars, and the other points are the same.

(Seventh invention) In the seventh invention, the above-mentioned reinforcing / cover receiving plate and earthquake-resistant plate are attached by bolts so as to be braced. For example, four mounting holes are provided in the wide mounting part of the earthquake-resistant plate, but if the bolts are tightened at diagonal positions, the brace effect can be exerted, so the mounting strength over the concrete foundation and the base wooden pillar is further increased. Improve.

(Eighth Invention) An eighth invention is an earthquake-resistant structure for reinforcing a concrete foundation, a base wooden pillar, and a vertical wooden pillar between vertical wooden pillars in a wooden house after construction. It depends on. The concrete foundation is provided with upper bolts projecting upward and side bolts projecting at right angles at the sides, on which the base wooden pillars are fixed horizontally. Vertical wooden pillars are erected vertically on the foundation wooden pillars on the concrete foundation.

At a predetermined position between the base wooden pillar and the vertical wooden pillar, an outer periphery and an inside are threaded and a nut is screwed. The reinforcing and cover receiving plate has a thickness substantially equal to the height of the step between the concrete foundation, the base wooden pillar, and has a mounting hole at the same position as the nut. The seismic plate has a length extending from the vertical wooden pillar to the concrete foundation, and has a mounting hole at the same position as the nut and the side bolt. The cover that covers the earthquake-resistant structure is previously attached to a reinforcing and cover receiving plate to which the cover attachment seat is attached.

(Ninth invention) The ninth invention is to provide a concrete foundation of a wooden house after construction, two foundation wooden pillars, and a corner part composed of a vertical wooden pillar vertically built at a joint of the foundation wooden pillars. It depends on the seismic fittings for reinforcement. According to a ninth aspect of the present invention, there is provided a quake-resistant bracket having a plurality of tapered nuts threaded to the outside and inside thereof for screwing into the predetermined positions of the base wooden pillar and the vertical wooden pillar; Two reinforcing and cover receiving plates that have a thickness substantially equal to the thickness of the nut and are provided with mounting holes at the same positions as the nuts, and that are reinforced from two sides, and a wide mounting portion that extends over the concrete foundation portion and the base wooden pillar portion. Two quake-resistant plates, each having a narrow mounting portion extending over a vertical wooden pole and having mounting holes at the same positions as the nuts and side bolts, and a cover mounting seat mounted on the reinforcing and cover receiving plate. And a cover that covers the corner and the upper part attached to the vehicle.

(Tenth invention) A tenth invention is an earthquake-resistant metal fitting for reinforcing the attachment of a concrete foundation, a base wooden pillar, and a vertical wooden pillar between vertical wooden pillars in a wooden house after construction. It depends on. Except for the shape of the cover, the shapes of the nuts threaded on the outer periphery and inside, the reinforcing and cover receiving plate, and the seismic plate are the same as those of the ninth invention. However, the cover of the tenth invention is different from the ninth invention in that the cover covers one side surface.

(Eleventh invention) An eleventh invention is an earthquake-resistant fitting for reinforcing the attachment of a concrete foundation, a base wooden pillar, and a vertical wooden pillar between vertical wooden pillars in a wooden house after construction. The present invention relates to a portion of the quake-resistant metal fitting which is less strong than the tenth invention. The difference from the tenth invention is that the width of the seismic plate is the same until it reaches the concrete foundation and the vertical wooden pillar. The eleventh invention is manufactured at a lower cost than the tenth invention.

(Twelfth invention) A twelfth invention relates to a cover of a seismic fitting. The cover of the earthquake-resistant bracket has a wider side near the concrete foundation than the upper part on the side of the cover, so that the inner bracket cannot be seen from a portion where there is no outer wall.
