DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brace fixing bracket used to increase the connection strength of a brace provided between a base and a pillar in a wooden building.

[0002]

2. Description of the Related Art In wooden buildings, bracing fixtures for reinforcing the structure of a base and a pillar are used. This fixture is attached to the lower end of a brace that is attached diagonally between the column and the base, and is used to increase the strength of the connection between the brace and the base and the column.

The bracing fixture is a fitting for simultaneously connecting the brace, the pillar and the base, and generally has a plurality of insertion holes for inserting nails or bolts into the plate-shaped fixture. Brace fixing brackets are used.

For example, Japanese Utility Model Application Laid-Open No. 6-49603 discloses a large-diameter hole for inserting a bolt to be passed through a brace and a small-diameter hole for inserting a nail or a wood screw in a plate surface of a fixing bracket. And a fixing bracket having a perforated hole.

On the other hand, in wooden buildings, anchor bolts for connecting a foundation and a base are used. In this anchor bolt, the lower end of the anchor bolt is embedded in a concrete foundation in advance, and the upper end is made to penetrate the base to fix the base to the foundation. When connecting an anchor bolt to a pillar, a pulling fitting is fixed to the side surface of the pillar, and an anchor bolt that has penetrated the base is connected to the pulling fitting.

[0006]

However, when the anchor bolt is connected to the pulling fitting, it is necessary to insert the anchor bolt near the column. Therefore, when the bracing fixture and the pulling hardware are used at the same time, the respective mounting positions are near the intersection between the pillar and the base. In this case, it is necessary to devise a brace and a mounting position of a brace fixing bracket so as not to hinder the connection between the anchor bolt and the drawing hardware.

[0007] Further, since the anchor bolts are to penetrate the core of the base, when these bracing fixing brackets and the pull-in hardware are simultaneously mounted, the anchor bolts penetrating the core are fixed by the bracing brackets. In many cases, the mounting work of the bracing fixture requires a lot of trouble.

[0008] These bracing fixtures and pull-in hardware are both important fittings for increasing the connection strength between the base and the pillar. Therefore, when both metal fittings are attached at the same time, and when the fixing metal fitting for bracing is arranged at a position overlapping the anchor bolt, more labor-intensive work such as making work on the fixing metal fitting for bracing is required. There is a possibility.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide a bracing fixture which can be easily attached even when a pull-in hardware is used. .

[0010]

In order to solve the above-mentioned problems, a first means of the present invention is to provide a pair of connecting means for connecting a column M and a base N from a fixing plate 1 connected to the end side surface of a brace P. In the bracing fixture having the plate 2 bent, the notch 3 through which the anchor bolt Q is inserted is symmetrically positioned at each connecting plate 2.
Has been established.

The fixing plate 1 of the second means has a square shape,
A plurality of connection holes 4 for inserting nails or wood screws are formed in the plate surface of the fixing plate 1 except for the position overlapping with the anchor bolt Q mounted through the cutout 3 of the connection plate 2.

The third means is that the connecting hole 4 of the fixed plate 1 is unevenly distributed on the side of the side edge where the connecting plate 2 is provided.
In addition, it is a means for solving the problem that the side edges are arranged at a position which is substantially radial from the corner where they come into contact.

According to the present invention, the notch 3 provided at the symmetrical position of each connecting plate 2 makes it possible to use the bracing fixture and the pull-in metal R at the same time. Also, since a pair of notches 3 are provided at symmetrical positions of the respective connection plates 2,
It can be attached to the column M at any of the left and right positions.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

The fixing bracket of the present invention is formed by punching a metal plate and forming a bend. The fixing bracket includes a fixing plate 1 connected to the end side surface of the brace P and a pair of connecting plates 2 connected to the column M and the base N, respectively. (See FIG. 4).

The fixing plate 1 has a square shape, and the connecting plate 2
The fixed plate 1 has a substantially rectangular shape bent from a pair of adjacent side edges. Each connecting plate 2 is provided with a notch 3. The notch 3 is a position where a bolt insertion hole N1 for inserting an anchor bolt Q penetrating the base N is opened (see FIG. 1). The anchor bolt Q is arranged at a position where it is connected to the pull hardware R fixed to the column M. The notch 3 is provided at a symmetric position of each connecting plate 2 (see FIG. 4). That is, these notches 3 are provided at equal intervals from the adjacent portion 2A of the connecting plate 2 and the position where the anchor bolt Q penetrates (the position where the pull-in metal R is fixed) is either left or right with respect to the column. This can be handled (see FIG. 1).

On the other hand, a plurality of connecting holes 4
Then, the fixing plate 1 and the side surface of the brace P are connected to each other through the connecting holes 4 through nails or wood screws. These connecting holes 4
Are arranged so as to be removed from a position overlapping the anchor bolt Q through the cutout 3 (see FIG. 2). In particular, it is provided so that the symmetrical side edge of the side edge where the connecting plate 2 is provided (side edge 1B where the connecting plate 2 is not provided) is increased. Furthermore, each of these connection holes 4 is arranged at a position which is substantially radial from the corner 1A where the side edge 1B of the fixed plate 1 where the connection plate 2 is not provided contacts. By arranging the connection holes 4 in this manner, the connection position between the brace P and the fixing plate 1 can be set at a position away from the attachment position of the anchor bolt Q. In addition, since the number of connection holes 4 increases as the distance from the anchor bolt Q increases, the connection work between the fixing plate 1 and the brace P is easy.

A plurality of connecting holes 5 are also formed in the surface of the connecting plate 2 (see FIG. 3). A nail or a wood screw is inserted through the connection hole 5, and each connection plate 2 is connected to the column M and the base N (see FIG. 1). It should be noted that the shape of the notch 3, the number of the connection holes 4 and 5, the arrangement position, and the like can be arbitrarily set without departing from the scope of the present invention.

The metal pull R is inserted into the bolt insertion hole N of the base N.
1 is connected to the anchor bolt Q inserted through
Fixed to Further, the pull hardware R is not limited to the illustrated example.

[0020]

According to the present invention, the above object has been attained.

That is, in a brace fixing bracket formed by bending a pair of connecting plates 2 connected to the column M and the base N from the fixing plate 1 connected to the end of the brace P, at the symmetrical positions of the connecting plates 2, By providing the notch 3 through which the anchor bolt Q is inserted, it is possible to use the pull-in hardware R, so that even when the anchor bolt Q is arranged near the column M, the fixture of the present invention can be attached very easily. Can be.

The fixing plate 1 has a square shape, and is provided with an anchor bolt Q mounted through the notch 3 of the connecting plate 2.
A plurality of connecting holes 4 through which nails or wood screws are inserted are formed in the plate surface of the fixing plate 1 where the position overlapping with the fixing plate 1 is removed, so that the fixing plate 1 can be bent without being hindered by the anchor bolt Q previously mounted. P can be easily connected.

Further, the connecting hole 4 of the fixing plate 1 is located at a position where the symmetrical side edge of the side edge where the connecting plate 2 is provided is unevenly distributed and substantially radially formed from the corner where the side edges contact. With the arrangement, as the distance from the mounting position of the anchor bolt Q at the brace P increases, more nails or wood screws can be used. As a result, the connection force between the brace P and the fixed plate 1 is increased, and a reliable connection strength is obtained.

As described above, according to the present invention, even if the pull-in hardware is used at the same time, it can be easily mounted, and furthermore, it has a beneficial effect that a reliable connection strength can be obtained.
