Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the structure of the streak in the frame of a wooden house, and particularly in the streak structure in the frame in which the strength of the streak is increased to increase the earthquake resistance, especially the strength against lateral wobbling. Regarding

[0002]

2. Description of the Related Art As shown in FIG. 5, a vertical column 1 called a through column and a horizontal column 2 such as a column 2a, a body insert 2b, a center insert 2d, and a base 2c are used in the framework of a wooden house. Each square member (or plate member) 3 is obliquely (diagonally) assembled so that the inclination angle θ becomes an obtuse angle in the square space formed by. The streak is attached to reinforce such a square space,
The purpose is mainly to increase the strength against the stress from the vertical direction, and therefore, when the stress from the lateral direction acts due to an earthquake, a strong wind, a collision of an object, etc., this square space cannot be maintained. That is, due to the impact from these lateral directions, the vertical columns 1 forming a square space,
If the horizontal pillar 2 is deformed or damaged, a disaster or an accident will occur. Such disasters and accidents have been experienced in the recent Great Kansai Earthquake, and although various methods of requesting the earthquake and various methods for reinforcing wooden houses have been proposed and implemented, each one of the conventional methods has been proposed. There is a limit to how strong the timber structure made of wood can maintain its strength, and for houses that use the current timber structure, it is possible that the damage and collapse of a house that had been damaged by the previous earthquake could be reproduced. The high of is more obvious than seeing the fire. Further, since the conventional Shinkai is composed of one piece of wood, it has a limit in strength against external force from the up and down direction and is not sufficient at all.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and is not only the strength against the external force from the lateral direction, which is the drawback of the conventional streak structure, but also the strength against the external force acting in the vertical direction. It is an object of the present invention to provide a thin structure that can realize a simple and low-cost structure and can be a countermeasure against an earthquake or the like. Further, in the streak structure of the present invention, since a unitized streak is prepared in advance and assembled at a predetermined location of the shaft assembly on site, the workability of assembling can be greatly improved.

[0004]

In order to achieve the above object, the invention of claim 1 is a streak used in a frame of a wooden house, and a plurality of streak crossing at a predetermined intersecting angle. It is characterized in that it is composed of wooden members, and that the crossing portion of each wooden member is a tenon-like fitting structure in which each wooden member central portion is provided in a similar manner. The invention according to claim 2 is characterized in that the above-mentioned streak is detachably assembled and fixed in a space formed between two vertical columns and upper and lower horizontal columns.

According to a third aspect of the present invention, there is provided a ridge structure in which the ridges made of the plurality of wooden members are assembled in a square frame body, and the square members are passed along the diagonal direction of the frame body. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is an example of a shaft assembly to which the shinkai 10 of the present invention is applied. In a square space excluding an opening 11 serving as a window, a doorway, etc., that is, each space formed by a vertical column 1 and a horizontal column 2, Assembling is completed by fitting the sliding unit 10 as shown in FIG. 2 and then fixing it with nails, bolts or the like. As the wooden member forming the shinkai, a square bar, a plate, etc. having a smaller diameter and a narrower width than the conventional shinkai can be used. FIG.
(1) The vertical unit 10 of (a) and (b) is a frame body 12 assembled in advance in a square shape so as to match the shape of the square space of the shaft-assembled column to be assembled, and the frame body 12 is slanted in a lattice pattern. And a plurality of wooden members 13 assembled so as to intersect with each other. Inclination angle of each wooden member 13,
The interval, the number, etc. can be appropriately selected. As a method of connecting the intersecting portions of the wooden members 13, the method of fitting the tenons with each other is the best in terms of strength. Since the mating structure of the mortises is well known, although not particularly shown, the half-notched groove formed at the proper position of one wooden member and the half-notched groove formed at the proper position of the other wooden member are fitted to each other. By doing so, both are connected and integrated. The connection between the outer peripheral frame 12 and the end of each wooden member 13 is performed, for example, by fitting the end of the wooden member in a recess provided in the frame 12 and then fixing the wooden member with nails, bolts, or the like. Good.

In the square space on the left side of the window-forming portion 11 of the shaft assembly of FIG. 1, there is no center insert 2c, and a vertically long slender unit is assembled. With this configuration, the number of steps for assembling the insert 2c can be saved, while maintaining the strength (strength in the lateral direction and the strength in the vertical direction) higher than that when the insert 2c is present.

When the sliding unit 10 itself is assembled in the square space of the shaft assembly, it is sufficient to simply fit the sliding unit 10 in the space and fix it with nails, bolts or the like. Workability is extremely excellent.
Incidentally, FIG. 3 is an example in which the sled unit of the present invention is applied to a Western-style shaft assembly, and when the spacing between the vertical columns is large as described above, a sled unit using a large number of wooden members is used accordingly. It will be created and applied.

FIG. 4 is a perspective view of a modified example of the present invention. The sled unit of this form example has a square bar (or plate member) 20 along a diagonal line with respect to the slid unit of the above form example.
It is characterized by the fact that it is integrated across all the. Both ends of the timber 20 are formed so as to fit in the corners of the frame body 12 as shown in the drawing, and at the location where the timber 20 intersects the wooden member 13, both the timber side and the wooden member side are required. By forming a groove and fitting both grooves together, it is taken into consideration that the square bar 20 does not extremely project from the frame 12. In this embodiment, the two square members 20 are attached to the front and back sides of the shinkai unit 10 so as to intersect each other along a diagonal line. However, only one of the square members 20 may be attached. According to this embodiment, the mechanical strength in the lateral direction and the vertical direction can be significantly improved as compared with the case of the above embodiment.

[0010]

As described above, according to the present invention, not only the strength against the external force from the lateral direction, which is a drawback of the conventional streak structure, but also the strength against the external force acting in the vertical direction is simple and the cost is low. It is possible to provide a fine structure that can be realized by the structure and can be used as a countermeasure against an earthquake or the like. Further, in the streak structure of the present invention, since a unitized streak is prepared in advance and assembled at a predetermined location of the shaft assembly on site, the workability of assembling can be greatly improved.
