DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to protecting an existing wooden building from earthquakes, and more particularly to a metal reinforcing material for a wooden building, which is fixed on a foundation to prevent the foundation from rising. It is.

[0002]

2. Description of the Related Art In a conventional wooden house, the base is generally fixed to a foundation by anchor bolts.

[0003]

However, even if the anchor bolts to be fixed to the base are insufficient, or if the anchor bolts or the like are used for fixing to the foundation, the anchor bolts may loosen due to aging. If the anchor bolts are insufficiently fixed, there is a problem in that the base rises due to the rising force of the earthquake, destroying the frame and causing the house to collapse.

The present invention has been made in view of the above problems, and has as its object to fix the foundation of an existing wooden house to the foundation, from outside the building and from inside the building. However, the present invention provides a reinforcing metal fitting for a base that can be mounted.

[0005]

In order to achieve the above object, a foundation reinforcing metal fitting for a wooden building according to the present invention comprises a side engaging portion and a through hole formed by bending an upper end of the side engaging portion. It has a horizontal upper surface engaging portion and a horizontal connecting surface portion with a through hole formed by bending the lower end, and has a U-shaped cross section integrally formed with reinforcing ribs on both longitudinal edges. An upper member, a flat plate having a predetermined area, a mounting surface portion having a large number of through holes, and a tip of an extended portion that is partially extended vertically upward from the center of the mounting surface portion to form a through hole. A lower member having a perforated horizontal mounting surface portion and integrally formed with reinforcing ribs on both edges of the extension portion and the horizontal portion, and a bolt and a nut for connecting the upper member and the lower member And the like. Further, it comprises a fixing member such as a bolt or a lag screw for fixing the upper member to the base, and a mounting member such as a hole anchor or an all anchor for fixing the mounting surface of the lower member to a foundation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a reinforcing bracket, and FIG. 2 is a sectional view showing an upper member and a lower member connected to each other. The reinforcing member A includes an upper member 1 and a lower member 2 and a tightening member 3 such as a bolt and a nut for connecting and tightening the upper member 1 and the lower member 2. The upper member 1 is attached to a side surface 4 a of a base 4. The upper surface 4b of the base 4 is formed by bending the upper end of the side surface engaging portion 5 at a right angle.
And a horizontal connecting surface portion 7 that supports one end of the clamp 3 by bending and extending the lower end at a right angle in a direction opposite to the upper surface engaging portion 6 to support the one end of the fastening 3. The reinforcing ribs 8a and 8b are integrally formed along the entire edges of the side surface engaging portion 5, the upper surface engaging portion 6 and the connecting surface portion 7 to form a U-shaped cross section. The upper surface engaging portion 6
Is formed with a through-hole 10 through which a fixing metal 9 such as a bolt or a lag screw is inserted, and a through-hole 11 through which the fastening metal 3 is inserted and supported is formed in the connecting surface 7. The through holes 10 and 11 are preferably formed as long holes so as to appropriately correspond to the mounting position of the upper member 1. Further, the side engaging portion 5 of the upper member 1 includes
A small hole 13 through which a stopper 12 such as a wood screw is inserted is formed,
The side engaging portion 5 is fixedly installed on the base 4 with the stopper 12.

The lower member 2 has a flat mounting surface portion 15 adhered to the side wall surface of the foundation 14.
The extension 16 has a horizontal connecting surface 17 which is bent at right angles at the tip of an extension 16 which is partially extended upward from above, and which supports the other end of the clamp 3 and both of the extension 16 and the connecting surface 17. Reinforcement ribs 18a and 18b are provided on the edges to be integrally formed. Further, a through hole 19 for inserting and supporting the tightening fitting 3 is formed in the connecting surface portion 17, and a mounting bracket 20 such as a hole anchor or an all anchor is inserted into the mounting surface portion 15. The plurality of bolt holes 21 are formed by drilling. It is preferable that the through-hole 19 is formed as a long hole so as to appropriately correspond to the mounting position of the upper member 1, and that the mounting surface portion 15 disperses the force as the area is increased, and Is preferably installed on the side surface of the foundation 14 in a firm and stable state.

FIG. 3 is a front view showing an example of use of the reinforcing metal fitting according to the present invention, and FIG. 4 is a cross-sectional view thereof. This figure shows a state in which it is used in combination with a corner reinforcing metal member capable of fastening a paddle. The corner metal reinforcing member B has an isosceles triangular plate portion 22 made of an iron plate and having a right angle at one corner. Side plates 23a, 2b, each of which is bent from two sides sandwiching a right angle of the portion 22 and whose corners are integrally connected by welding.
3b, a through hole 24 for inserting a bolt, a lag screw or the like, and a small hole (not shown) for a wood screw are formed in these two side plate portions 23a and 23b.
Is formed to have a through hole 26 for a bolt for fastening a brace 25 and a small hole 27 for a wood screw.

The corner fitting reinforcing metal B is installed at the corner between the base 4 and the column 28, and in this state, the upper member 1 of the reinforcing metal A of the present invention is attached to the upper surface engaging portion 5 and the corner. It comes into contact with the side plate portion 23a installed on the base 4 of the reinforcing metal B, and penetrates the through hole 10 of the upper surface engaging portion 6 and the through hole 24 of the side plate portion 23a to penetrate the fixing metal 9 such as a lag screw. It is screwed into the base 4 through the holes 10 and 24 and fixed. Next, the mounting surface portion 15 of the lower member 2 of the reinforcing metal A is fixedly installed via a mounting bracket 20 such as a hole anchor or an all anchor which is embedded and installed in the foundation 14. And
The upper member 1 and the lower member 2 are installed by connecting and tightening the connecting surfaces 7 and 17 of each other with a tightening fitting 3 such as a bolt and a nut. Reference numeral 29 denotes a tree that fills a gap between the side engaging portion 5 of the upper member 1 of the reinforcing member A and the base 4.

FIG. 5 is a front view showing a state in which the reinforcing metal fitting of the present invention and the corner-mounting reinforcing metal are used together, and FIG. 6 is an enlarged perspective view of a main part thereof. -A bracing is provided. In this state, the base 4 is stably installed on the foundation 14 by using the reinforcing metal A according to the present invention in combination with the corner reinforcing metal B in the same manner as described above. The mouth is reinforced, preventing the column from being pulled out. As a result, it is possible to prevent the collapse of the house due to the earthquake by increasing the reinforcement of the structure of the whole building.

In FIGS. 3 to 5, the reinforcing metal of the present invention is used together with the reinforcing metal at the corner, but it is a matter of course that the horizontal upper part of the reinforcing metal can be directly installed on the base and used alone. .

[0012]

Since the present invention has the above configuration,
By installing the reinforcing hardware, the anchor bolts can be reinforced, the base can be prevented from rising, and the frame of the wooden house can be prevented from being destroyed. As a result, the house can be prevented from collapsing. In particular, when used in combination with the corner reinforcement metal, there is an effect that it is possible to prevent the columns from being lifted up and to more effectively prevent the house from collapsing.
