DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a structural member in a wooden building, for example, a connecting structure of a column and a beam, a connecting structure of a beam and a beam, a connecting structure of a foundation and a column, and the like. It is an object of the present invention to provide a connection structure excellent in earthquake resistance.

[0002]

2. Description of the Related Art In recent years, earthquake-resistant structures in wooden buildings have been reviewed with lessons learned from the collapse of houses due to the earthquake.

[0003] Such a review of the seismic structure has been carried out from various viewpoints, but the most worrying point is that in a conventional wooden building, the connection structure of columns and beams sufficiently withstands the impact of an earthquake. It has no strength. The main cause of house collapse is that the conventional connection structure mainly focuses on supporting the load of the house in a stationary state, so if it is shaken or impacted by an earthquake, the connection part is easily separated and the load is applied there. Seen at the point of collapse.

Therefore, as a method for improving the conventional connection structure, a so-called metal fitting construction method of connecting and fixing components together by a connection metal fitting has been attracting attention without satisfying the traditional connection structure using a tenon.

[0005]

Various connecting fittings have already been proposed for implementing the above-mentioned fitting method, but there are still many unsolved problems.

[0006] In general, the connecting fitting is fixed to the wooden structure by bolts and nuts. However, the techniques proposed so far do not take into account the locking of the bolts and nuts. Therefore, wooden buildings using connecting metal fittings may have excellent seismic resistance at the completion of construction, but if bolts and nuts become loose due to aging, the connecting metal fittings may fall off, reducing the significance of the metal fitting method by half. I do. For this reason, it is desired to provide a technique provided with a reliable loosening prevention means.

[0007] When constructing a wooden building by the metal fitting method, it is preferable to standardize the structure and the connecting metal fittings, and to make them manual so that site workers such as carpenters can perform construction work according to predetermined procedures. . Therefore, in this case, the standardized structure and the connection fitting are manufactured at the factory. However, the components of a wooden building
Even in the case of factory production, it is inevitable that dimensional variations occur in the wood, and there is a limit to the accuracy of the standard. Therefore, a dimensional error occurs when assembling on site. This dimensional error can be corrected by a site worker by cutting or the like, but forcing such a process to the site is
Does not conform to the purpose of standardization and manualization. For this reason, it is desired to provide a technique capable of absorbing the dimensional error as described above by the connection fitting.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

(First Embodiment) FIGS. 1 and 2 show a first embodiment, in which a wooden pillar 4 (attached body 1) and a kiguchi end facing the pillar 4 from a cross direction. The structure in which the selected wooden beam 5 (attachment body 2) is connected by the connection fitting 3 is shown.

The connecting metal fitting 3 integrally includes a thick plate-shaped base plate 6 made of a thick metal plate and a wing piece 7 made of a metal plate projecting substantially perpendicularly from the base plate 6 by welding or the like. A support plate 8 made of a metal plate is provided extending from the lower end of the base plate 6 and fixed along the lower end of the wing piece 7 by welding or the like.

The board-shaped base 6 has a plurality of first insertion holes 9 perforated at a plurality of positions, in the example shown in FIG.
The insertion hole 9 has a large-diameter opening 9 a which forms a hole of a different diameter and faces the surface of the base plate 6. On the other hand, the wing piece 7 has a plurality of, in the illustrated example, two second insertion holes 10 arranged in the vertical direction and is notched at the upper edge of the wing piece 7. A pin receiving portion 11 is provided. Pin receiver 11
Is opened at the upper edge of the wing piece portion 7, and a tapered guide edge 11a is formed at the opening edge.

The pillar 4 (the body 1 to be mounted) has a shallow recess 12 formed in the surface thereof and a first bolt hole 13 formed near the four corners of the recess 12. Bolt hole 1
The reference numeral 3 is formed so as to penetrate the column 4 in the X direction. Then, as shown in FIG. 2 (A), when the base plate 6 of the connection fitting 3 is fitted into the seat recess 12, the first insertion hole 9 and the first bolt hole 13 are aligned with each other. The first base bolt 14 is inserted and the nut 15a is tightened, so that the board-shaped base 6 can be connected to the seat recess 1.
2 In this state, the head 14 of the bolt 14 is
a or the nut 15a is housed in the large-diameter opening 9a. The surface portion 6 a of the thick base 6 protrudes from the shallow seat recess 12 and protrudes from the surface of the column 4.

The beam 5 (attachment 2) is provided with a slit 30 cut from the end of the opening so that the wing 7 of the connection fitting 3 can be inserted, and a base plate 6 protruding from the surface of the column 4. A receiving recess 15 is formed to receive the surface portion 6a, and a second bolt hole 16 is formed in the Y direction passing through the slit 30 and crossing the beam 5. The second bolt hole 16 is formed in the second through hole 10 of the wing piece portion 7,
10 are provided at two places. Furthermore,
The slit 3 is located above the upper second bolt hole 16.
A pin 17 is inserted in the Y direction passing through the beam 0 and crossing the beam 5, and the pin 17 corresponds to the pin receiving portion 11.

Therefore, when connecting the beam 5 to the connection fitting 3 attached and fixed to the column 4, the beam 5 is lowered with the upper end of the wing piece portion 7 and the lower end opening of the slit 30 aligned. For example, the pin 17 is fitted into the pin receiving portion 11 while the wing portion 7 enters the slit 30, and the bottom of the beam 5 is supported by the support plate 8. The pin 17 is connected to the guide edge 11a.
The beam 5 enters the pin receiving portion 11 while attracting the beam 5 to the column 4 along the surface of the base 6.
a, and the positioning is automatically performed so that the second insertion hole 10 and the second bolt hole 16 coincide with each other, so that the second bolt 18 is inserted as shown in FIG. At the same time, the wing piece 7 is fixed to the beam 5 by tightening the nut 19a. In the drawing, reference numeral 18a denotes a head of the second bolt 18.

In the state where the beam 5 is connected and fixed to the column 4 via the connection fitting 3, as shown in FIG. 2, the bottom of the receiving recess 15 of the beam 5 (the mounting body 2) is The slack stopper 20 abuts or approaches the bolt head 14a or the nut 15a. In the case of the illustrated embodiment, the loosening stopper 20 closes the large-diameter opening 9a that accommodates the bolt head 14a or the nut 15a.

In the case where the loosening prevention portion 20 is configured to contact the bolt head 14a or the nut 15a, the bolt head 1

5a, the bolt head 14a or the nut 15a is rotatable in the slack direction until the bolt head 14a or the nut 15a comes into contact with the slack stopper 20. So that the bolt 14
And the nut 15a does not loosen.

FIG. 3 shows the relationship between the column 4 and the beam 5 produced at the factory and the connection fitting 3. In contrast to the distance L1 between the pillar centers set in the architectural design, the distance L2 between the pillar surfaces to be actually constructed has variations due to a dimensional error at the time of lumber. Therefore, when the beam 5 having the same length as the distance L2 based on the design numerical value is factory-produced, the beam 5 does not fit between the columns 4 and 4 at the time of assembling at the site, or the tip end of the beam 5 and the column 4 This causes a situation in which there is a play space between them.

Therefore, in the present invention, the seat recess 12 is machined and formed with reference to the center of the column 4 at the time of factory production. That is, processing is performed so that the dimension T1 between the bottom of the seat recess 12 and the center of the column becomes a constant value. Then, the connecting bracket 3

For this reason, when producing the beam 5 at the factory,
The distance L4 between the receiving recesses 15 at both ends of the beam 5 is L
4 = L3, the loosening prevention portion 2 of the beam 5
The beam 5 and the column 4 can be connected and fixed in a state where 0 is always adapted to the surface of the base plate 6. And at this time,
If the actual overall length L5 of the beam 5 exceeding the receiving recess 15 is formed to be slightly shorter than the distance L2 between the column surfaces expected in advance, for example, about 2 mm shorter, the beam 5 will be It does not happen that it does not fit in.

By forming L5 <L2 as described above, as shown in FIG. 2A, the end face of the beam 5 (the end face of the portion projecting beyond the receiving recess 15) and the surface of the pillar 4 are formed. However, as described above, the anti-loosening portion 20 and the board-shaped base portion 6 are always fitted, and the pillar 4, the connecting fitting 3 and the beam 5 are strongly connected and fixed.
