Abstract

To provide a joint structure of a wooden building having high strength.SOLUTION: There is provided a joint structure of a wooden building that joins members constituting a framework using a drift pin, in which the drift pin is arranged in a direction oblique to a side face of the member.SELECTED DRAWING: Figure 1

Description

本発明は、木造建物、特に木造軸組建物において用いられる接合構造に関するものである。   The present invention relates to a joint structure used in a wooden building, particularly a wooden framed building.

木造軸組建物においては、柱や横架材など軸組を構成する部材同士を、金物を介して接合することが一般的になっている。
特に、柱と横架材の接合においては、連結パイプをそれぞれの下穴に挿入し、側方からドリフトピンを挿通して固定する方法が知られている。 In a wooden framed building, it is common to join members constituting a frame, such as pillars and horizontal members, via hardware.
In particular, in joining a column and a horizontal member, a method is known in which a connecting pipe is inserted into each prepared hole, and a drift pin is inserted and fixed from the side.

特開２０１７−２０２２２号公報JP 2017-20222 A

従来の連結パイプを用いた接合構造において、ドリフトピンは部材の面に対して垂直に挿入するため、ドリフトピンの長さは短くなる（図５）
地震等により柱に作用した力は、連結パイプからドリフトピンを介して横架材に伝達する。
ドリフトピンの長さが短いと、横架材に作用するドリフトピンの単位長さあたりの力は大きくなり、横架材が破損するおそれがある。 In a conventional joining structure using a connecting pipe, the length of the drift pin is reduced because the drift pin is inserted perpendicularly to the surface of the member (FIG. 5).
The force acting on the column due to an earthquake or the like is transmitted from the connecting pipe to the horizontal member via the drift pin.
If the length of the drift pin is short, the force per unit length of the drift pin acting on the horizontal member increases, and the horizontal member may be damaged.

本発明は、高強度な木造建物の接合構造を提供することを目的とする。   An object of the present invention is to provide a joint structure for a wooden building with high strength.

上記目的を達成するためになされた本願の第１発明は、ドリフトピンを用いて軸組を構成する部材同士を接合する、木造建物の接合構造であって、前記部材の側面に対して斜めの方向にドリフトピンを配置することを特徴とする、木造建物の接合構造を提供する。
本願の第２発明は、柱と横架材とを連結パイプを介して接合する、木造建物の接合構造であって、前記横架材と前記連結パイプを接合するドリフトピンは、前記横架材の側面に対して斜めの方向に配置することを特徴とする、木造建物の接合構造を提供する。
本願の第３発明は、第２発明の木造建物の接合構造において、前記柱と前記連結パイプを接合するドリフトピンは、前記柱の側面に対して斜めの方向に配置することを特徴とする、木造建物の接合構造を提供する。 A first invention of the present application made to achieve the above object is a joining structure of a wooden building, in which members constituting a frame are joined using a drift pin, wherein the joining structure is oblique to a side surface of the member. Provided is a joining structure for a wooden building, wherein a drift pin is arranged in a direction.
A second invention according to the present application is a joining structure for a wooden building, in which a pillar and a lateral member are joined via a connecting pipe, wherein the drift pin that joins the lateral member and the connecting pipe includes the lateral member. The present invention provides a joining structure for a wooden building, wherein the joining structure is arranged in a direction oblique to a side surface of a wooden building.
A third invention of the present application is the joint structure for a wooden building according to the second invention, wherein the drift pins that join the column and the connection pipe are arranged obliquely to a side surface of the column. Provides a joint structure for wooden buildings.

本発明は、上記した課題を解決するための手段により、次のような効果の少なくとも一つを得ることができる。
（１）ドリフトピンを部材に対して斜めに配置することにより、ドリフトピンの長さが長くなる。これにより、部材に作用するドリフトピンの単位長さあたりの力は小さくなり、部材が破損するおそれが少なくなり、高強度の接合構造とすることができる。
（２）ドリフトピンを斜めに配置することにより、他の部材や受け金物などの金物に干渉せず、最適な手順で部材を接合することができる。 According to the present invention, at least one of the following effects can be obtained by means for solving the problems described above.
(1) By arranging the drift pins obliquely with respect to the member, the length of the drift pins becomes longer. Accordingly, the force per unit length of the drift pin acting on the member is reduced, and the member is less likely to be damaged, and a high-strength joint structure can be obtained.
(2) By arranging the drift pins diagonally, the members can be joined in an optimal procedure without interfering with other members or hardware such as receiving hardware.

以下、図に示す実施例に基づき、本発明を詳細に説明する。   Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

［実施例１］
（１）接合構造
本発明の接合構造は、木造軸組建物において、横架材１と柱２とを接合して固定する構造である。
本発明の接合構造は、横架材１と柱２の内部に位置する連結パイプ３、横架材１に挿通する長ドリフトピン４１、および、柱２に挿通する短ドリフトピン４２と、を有する。（図１） [Example 1]
(1) Joint structure The joint structure of the present invention is a structure in which a horizontal member 1 and a column 2 are joined and fixed in a wooden frame building.
The joint structure of the present invention has a connecting pipe 3 located inside the horizontal member 1 and the column 2, a long drift pin 41 inserted into the horizontal member 1, and a short drift pin 42 inserted into the column 2. . (Fig. 1)

（２）連結パイプ
連結パイプ３は円筒状の部材である。（図２）
連結パイプ３は軸と直交する方向に長ドリフトピン４１または短ドリフトピン４２を挿通する側孔３１を設ける。
本実施例において、連結パイプ３に設ける側孔３１は、横架材１側には３カ所、柱２側には２カ所設ける。
連結パイプ３の下部は柱２に設けた下穴２１に挿入する。また、連結パイプ３の上部は横架材１に設けた下穴１１に挿入して固定する。 (2) Connecting pipe The connecting pipe 3 is a cylindrical member. (Fig. 2)
The connecting pipe 3 is provided with a side hole 31 through which the long drift pin 41 or the short drift pin 42 is inserted in a direction orthogonal to the axis.
In this embodiment, three side holes 31 provided in the connecting pipe 3 are provided on the side of the horizontal member 1, and two side holes 31 are provided on the column 2.
The lower part of the connecting pipe 3 is inserted into a pilot hole 21 provided in the column 2. The upper part of the connecting pipe 3 is inserted and fixed in a prepared hole 11 provided in the horizontal member 1.

（３）ドリフトピンの配置
柱２側の短ドリフトピン４２は、四角形の柱２の側面に直交するように、かつ、互いに平面視直交する方向に設けたピン孔２２に挿通する。このため、短ドリフトピン４２は、柱２の幅とほぼ同じ長さとなる。
一方、横架材１側の長ドリフトピン４１は、横架材１の側面に対して斜めになるように設けたピン孔１２に挿通する。このため、長ドリフトピン４１は横架材１の幅よりも長くなる。本実施例においては３本のピン孔１２のうち真ん中のピン孔１２を他のピン孔１２に対して平面視交差するように設けるが、３本を平行に設けてもよい。 (3) Arrangement of Drift Pin The short drift pin 42 on the column 2 side is inserted into the pin hole 22 provided so as to be perpendicular to the side surface of the rectangular column 2 and to be perpendicular to each other in a plan view. For this reason, the short drift pin 42 has substantially the same length as the width of the column 2.
On the other hand, the long drift pin 41 on the side of the horizontal member 1 is inserted into the pin hole 12 provided obliquely with respect to the side surface of the horizontal member 1. For this reason, the long drift pin 41 is longer than the width of the horizontal member 1. In the present embodiment, the center pin hole 12 of the three pin holes 12 is provided so as to intersect the other pin holes 12 in a plan view, but the three pin holes 12 may be provided in parallel.

（４）連結パイプの側孔
連結パイプ３には、ピン孔１２、２２に対応する位置に側孔３１を形成する。
横架材１側の長ドリフトピン４１は横架材１の側面に対して斜めになるように設け、柱２側の短ドリフトピン４２は柱の側面に直交するように設ける。
このため、横架材１側の側孔３１の組と、柱２側の側孔３１の組は、異なる角度を呈する。 (4) Side Holes of Connection Pipe Side holes 31 are formed in the connection pipe 3 at positions corresponding to the pin holes 12 and 22.
The long drift pin 41 on the side of the horizontal member 1 is provided to be oblique to the side surface of the horizontal member 1, and the short drift pin 42 on the side of the column 2 is provided to be orthogonal to the side surface of the column.
For this reason, the set of the side holes 31 on the horizontal member 1 side and the set of the side holes 31 on the column 2 side have different angles.

（５）長ドリフトピンの作用
長ドリフトピン４１は横架材１に対して斜めに配置されるため、直交するように配置される場合に比べて長さが長くなる（図２）。
地震等により柱２に作用した力は、連結パイプ３から長ドリフトピン４１を介して横架材１に伝達するが、長ドリフトピン４１の長さが長いため、横架材１に作用するドリフトピンの単位長さあたりの力は小さくなり、横架材１が破損するおそれが少なくなり、高強度な接合構造となる。 (5) Operation of Long Drift Pin Since the long drift pins 41 are arranged obliquely with respect to the horizontal member 1, the length thereof is longer than that in the case where they are arranged orthogonally (FIG. 2).
The force acting on the column 2 due to an earthquake or the like is transmitted from the connecting pipe 3 to the transverse member 1 via the long drift pin 41. However, since the long drift pin 41 is long, the drift acting on the transverse member 1 is increased. The force per unit length of the pin is reduced, and the risk of damaging the horizontal member 1 is reduced, resulting in a high-strength joint structure.

また、横架材１と直交する別の横架材１ａを受け金物５により接合する場合、横架材１に対して斜めにピン孔１２を設けることにより、横架材１ａや受け金物５がピン孔１２に干渉せず、受け金物５や横架材１ａを取り付けた後でも、柱２と横架材１を接合することができる。   When another horizontal member 1a orthogonal to the horizontal member 1 is joined to the metal member 5 by receiving the metal member 5, the pin member 12 is provided obliquely with respect to the horizontal member 1 so that the horizontal member 1a and the metal member 5 can be joined. The column 2 and the horizontal member 1 can be joined even after attaching the receiving hardware 5 and the horizontal member 1a without interfering with the pin hole 12.

［実施例２］
（１）柱側のドリフトピンの配置
上記実施例において、柱２側のドリフトピンは、柱２の側面に直交するように設けたが、柱２の対角線方向にピン孔２２を設けてもよい。
対角線方向にピン孔２２を設けることで、柱２の側面に直交する構成よりも長い長ドリフトピン４１となり、高強度な接合構造となる。 [Example 2]
(1) Arrangement of Pillar Drift Pin In the above embodiment, the pillar 2 side drift pin is provided so as to be orthogonal to the side surface of the pillar 2, but the pin hole 22 may be provided in the diagonal direction of the pillar 2. .
By providing the pin holes 22 in the diagonal direction, the long drift pin 41 becomes longer than the configuration orthogonal to the side surface of the column 2, and a high-strength bonding structure is obtained.
