るのが普通である。2. Description of the Related Art Wooden buildings can provide high strength against rolling in the event of an earthquake or the like by providing bracing in the wall space between adjacent columns. In recent years, it is desired to construct a high-strength wall with excellent seismic resistance by providing this bracing. The bracing structure for this purpose is
A brace is provided along a diagonal line in a rectangular wall space (the thickness of the space corresponds to the thickness of the pillar) formed by the vertical pillars, the lower base, and the upper girder (horizontal member). Method: A method of intersecting X-shaped bracing along two diagonal lines and a method of connecting and fixing braced materials crossed in X-shape with nails etc. to improve the strength are required. Conventionally, these braces are usually constructed on site.

費のコスト上昇を招くことが問題となる。[0003] As described above, it is recommended to provide a bracing structure to form a bearing wall having a high wall ratio in order to improve earthquake resistance. It is necessary to provide a temporary bracing, so that the number of man-hours required for construction and the period of construction work are prolonged, which leads to a problem that construction costs are increased.

Have been proposed and used in practice. As a conventional example of such a wall strength imparting panel, for example, a precast type panel in which an X-shaped cross brace is previously installed along a diagonal line inside a rectangular (rectangular) frame material is known. I have. The rectangular frame type precast panel is used after being manufactured at a wood processing factory, and then transported to a building construction site by a truck or the like and fitted into a predetermined wall space.

ある。[0005] However, such a rectangular frame structure precast type wall strength imparting panel has the following problems. In other words, in wooden buildings, there are basically no major changes because the adjacent pillars are designed and constructed to have a fixed spacing specified by the Building Standards Law, but the base and girder etc. are at the request of the owner. Since there is a tendency to be designed with various specifications, especially the vertical (vertical) dimensions of the wall space into which the panels are fitted often differ from building to building, and are limited to commonly known combinations of materials such as flooring materials and girder materials. There are about 80 kinds of differences in dimensions,
Therefore, a panel for each of these different dimensions is required. Therefore, the above-mentioned rectangular frame-type wall strength imparting panel is a kind of custom-made type manufactured according to the design dimensions of each building, and is not suitable for mass-producing the same general-purpose product. There are structural disadvantages. As a result, in the case of using such a rectangular frame structure precast type wall strength imparting panel, although the advantage of using a precast type panel that can shorten the period of on-site work can be obtained for the time being, it is not easy to reduce the panel manufacturing cost. In addition, large-scale storage facilities are required to produce and store various types of panels, each of which requires an average of about 50 panels per building, and this is not appropriate. There is a problem that there are many inconveniences.

る。In addition to the above problem, there is another problem that a panel having a rectangular frame structure cannot easily change its outer dimensions. That is, even if the dimensions of the panel are accurately made, it is often unavoidable that the wall space dimensions of the building under construction are slightly out of alignment. Since the panel cannot be fitted into the wall space even with a slight deviation, it is necessary to adjust the external dimensions formed by the rectangular frame material. However, it is unavoidable that this rework is a work to correct the external dimensions of the rectangular frame structure, and it is inevitable that a considerable amount of time will be taken.This will reduce the construction period, which is an advantage of using precast panels. It is not preferable because the result cannot be obtained.

で緊結する構成とすることが考えられる。Therefore, the problem in the conventional precast type panel having such a rectangular frame structure, particularly the problem when there is a slight deviation between the design dimensions of the wall space of the building and the production dimensions of the panel can be solved with a simple operation. It is possible to do so. As such an example, for example, a precast type panel is not proposed.
No. 4253, Japanese Unexamined Patent Publication No. 8-270101, etc., specifically, as shown in FIG. 7A, two bracing members 300, 301 are laminated and crossed in an X-shape. 7B, a precast panel is formed by connecting and fixing with a nail 304 at the intersection 303, or a plywood 305 is laminated on the intersection 303 as shown in FIG. 7B to form a precast panel. The upper and lower ends are attached to the base 306 and the girder 307 by the fastening fittings 308, 309.
It is conceivable to adopt a configuration that ties together.

As can be seen from FIG. 7, slight deviations in the vertical dimension of the wall space and the panel bracing can be absorbed by the ties, and in some cases, the ends of the two crossing braces may be cut off. Therefore, it is possible to perform the fitting operation easily and in a short time because the dimension can be adjusted relatively easily.

【発明が解決しようとする課題】しかし、本発明者が更
に検討したところによれば、基本的には２本の筋かい材
だけで製作するようにした上記の構造のパネルには未だ
改善すべきいくつかの課題があることが分かった。However, according to further studies by the present inventor, a panel having the above structure, which is basically made of only two bracing members, has not been improved. It turns out there are some challenges to be taken.
【００１０】その第一は壁耐力の倍率向上の効果が不十
分という問題であり、第二は壁空間の有効利用を図るた
めには上記構造は適当でないという問題である。The first problem is that the effect of increasing the magnification of the wall strength is insufficient, and the second problem is that the above-described structure is not appropriate for effective use of the wall space.
【００１１】前者の壁耐力の倍率向上については、例え

るだけ太い材の使用が望まれる。しかし、図７に示した
２本の筋かい材を積層交叉する構造では、壁空間の厚み
に制約されて太い材の使用は難しい。For the former improvement in the magnification of the wall proof stress, for example, the following problem arises. That is, even if the structure is such that two bracing members that are more effective in increasing the wall strength than one bracing are provided in an X-shape (cross), if the bracing material used is a thin material. The wall magnification defined by the Building Standards Law is low (for example, 3 times for 30 mm × 90 mm), but becomes high when thick materials are used (for example, 45 mm × 90 m).
Therefore, it is desirable to use a material as thick as possible to enable a high wall magnification. However, in the structure in which two bracing members are stacked and crossed as shown in FIG. 7, it is difficult to use a thick member due to the limitation of the thickness of the wall space.

ど作業が面倒になることが避けられない。The above also leads to a problem that it is not advantageous for effective use of the wall space. That is, the wall space is used not only for providing the bracing, but also as a filling space for the heat insulating material and a mounting space for the drawn-out hardware (hole-down hardware). In the case where is used, since two bracing members are displaced in the thickness direction, it is not easy to secure a space. Also, the work of inserting the panel into the wall space and connecting and fixing it to the base or the like is troublesome, for example, since the posture of the panel is not stable, it is necessary to provide a temporary bracing or to perform it with two or more workers. That is inevitable.

る。Therefore, the present inventor has solved the above-mentioned problems and has proposed a structure of a precast-type wall bearing panel which is suitable for constructing a bearing wall with a high wall magnification, specifically, a bracing material is simply used. The present inventors considered an X-shaped bracing structure that can effectively utilize the wall space by being present in one plane, and can be manufactured easily and at low cost. The present invention proposes a joint which is useful for constructing a panel having such a structure.

る。In the above description, the vertical rectangular shape of the X-shaped bracing structure corresponds to a wall space (an adjacent column,
(A space surrounded by a base and a girder). The standard dimensions of the rectangle are not limited, but the vertical dimension is, for example, two 2730 mm and 2550 mm, which are typical dimensions for a building, and the horizontal dimension is, for example, 790 mm and 1260 mm. Can be
The reference vertical and horizontal dimensions of the panel are determined by the combination of these four types of reference dimensions. The deviation of the wall space to be fitted with the panel from the reference dimension in the vertical direction can be dealt with by modifying the panel manufactured at the reference dimension at the site or at the factory. It is appropriate to perform rework by cutting or cutting the end of the bracing material. Therefore, as the actual panel manufacturing dimensions, the maximum vertical dimension in the range of approximate dimensions that can be reworked is determined by the panel manufacturing. It is good to adopt it as a production standard size for. In this way, when a panel having a slightly shorter dimension is required, the panel can be modified into a panel that fits into a target wall space by shaving or cutting off the end of the bracing material. The bracing material is not limited, but has a thickness 4 capable of forming a high strength wall having a wall magnification of 4.
A material of 5 mm × 90 mm in width is preferably adopted, and the advantage of the present invention as compared with the conventional bracing structure in which the use of such a material is difficult is most typically exhibited.

This joint is used to firmly connect and fix two short bracing members, and the application of the joint is such that the two short bracing members are located in a single (same) plane as the long bracing members. In this manner, the long struts are applied at the positions corresponding to the intersections of the diagonal lines, and the struts located on these single planes are connected and fixed. As a result, it is possible to form a high-magnification load-bearing wall of four times, and to secure a uniform flat space suitable for accommodating a heat insulating material or the like in the wall space. According to the configuration of the present invention, the wall magnification can be increased to 5 times by further attaching a gypsum board.

It has a bent flange portion that bends and adheres to the surface in the thickness direction of these short bracing members, and the bent flange portion can be formed by bending a metal plate. The bent flange portion is for increasing the section modulus, thereby improving the bending rigidity of the joint. The material of the joint only needs to have strength equivalent to the tensile strength and compressive strength (tensile fracture strength and compressive fracture strength) of the bracing material (wood), and the type of metal plate used for this And the thickness are selected from a range satisfying this condition. Generally, a zinc-plated iron plate having a thickness of several mm to about several tens mm is preferably used.

号にダッシュ記号（’）を付して示し説明は省略する。Embodiment 2 The wall strength imparting panel 170 of this example shown in FIG. 6 corresponds to a case where the interval between the columns 201 is set to be wider (longer), for example, 1260 mm, as compared with the configuration of the above-mentioned Embodiment 1. FIG. 2 shows a panel having a configuration similar to that of the first embodiment. That is, the lateral dimension of the panel is, for example, 1259 mm, which is 1 mm shorter than the interval between the columns, and with the increase in the lateral interval, the middle rails 141 (upper side) and 142 (lower side) are each positioned at two positions in the lateral direction. In this case, the outer wall material can be securely fixed by juxtaposing the studs 150. In response to this, the studs 150 are similarly juxtaposed at two lateral positions to securely fix the interior material. However, the types and numbers of the constituent members are the same. Therefore, the configuration of the joint used in this example is only different in dimensions, and the basic configuration is the same. Therefore, the same reference numerals are attached with dashes (') and the description is omitted.

Using fixed hardware such as hardware)
As in the first embodiment, the work of constructing a bearing wall by firmly fixing to a predetermined object such as the base 202, the eaves girder 203, and the pillar 201 can be performed. Further, since the panel 170 is lighter in weight than the conventional panel, the advantage that the operator can perform the work at this time by himself is also exhibited. For this reason, the construction of the load-bearing wall can be performed extremely easily and in a short time, and the temporary fixing using the standing frames 131 and 132 allows the assembling work of the pull-out hardware to be easily and easily performed. The advantage that the temporary fixing work of the standing frames 131 and 132 itself is easy because the reinforcing plate is divided into upper and lower parts and the middle part is opened is also provided.
