Description

本発明は、木造建築などにおいて、隣接する部材同士を一体化するために用いる連結構造に関する。 The present invention relates to a connecting structure used to integrate adjacent members in a wooden building or the like.

木造建築などの木構造において、隣接する部材同士を一体化する手段は様々だが、部材の加工や現地での作業を簡素化するため、各種金物を用いることがある。この金物の形状や使用方法は様々だが、広く使用されているものとしてホゾパイプが挙げられる。ホゾパイプは、金属管を切り出しただけの単純な形状で、これを隣接する部材同士の境界を跨ぐように埋め込み、さらにホゾパイプの側周面と交差するようにボルトやドリフトピンなどを差し込み、部材とホゾパイプを一体化する。このようにホゾパイプを用いる場合、部材に複雑な加工を施す必要がなく、しかもホゾパイプは、安価であるほか、引張荷重とせん断荷重の両方を受け止めることができるなど、様々な利点を有する。 In a wooden structure such as a wooden building, there are various means for integrating adjacent members, but various hardware may be used to simplify the processing of the members and the work in the field. There are various shapes and usages of this hardware, but one that is widely used is the hozo pipe. The hozo pipe is a simple shape made by cutting out a metal pipe, embedding it so as to straddle the boundary between adjacent members, and inserting bolts and drift pins so as to intersect the side peripheral surface of the hozo pipe, and then the member. Integrate the hozo pipe. When the hozo pipe is used as described above, it is not necessary to perform complicated processing on the member, and the hozo pipe has various advantages such as being inexpensive and being able to receive both a tensile load and a shear load.

本発明と関連のある先行技術の例として後記の特許文献が挙げられ、そのうちの特許文献１では、抜け止め強度が高く、しかも簡易な構成で施工も容易に行うことのできる柱木材との継合具が開示されている。この継合具は、筒状の基体の底部に係止鍔部を設けてあるほか、基体の側周面には係止ピンを差し込むための係止孔を設けてある。そして土台と柱木材など、隣接する二部材の境界を跨ぐように基体を埋め込み、さらに部材の表面から係止孔に向けて係止ピンを差し込むことで、二部材が一体化される。なお係止鍔部は、一方の部材の底面に接触させる。その結果、抜け止め強度が高まり、優れた耐震強度を発揮する。 As an example of the prior art related to the present invention, the patent document described later is mentioned, and in the patent document 1 among them, the joint with the pillar timber which has high retaining strength and can be easily constructed with a simple structure. The condition is disclosed. In this joint, a locking flange is provided at the bottom of the tubular substrate, and a locking hole for inserting a locking pin is provided on the side peripheral surface of the substrate. Then, the two members are integrated by embedding the substrate so as to straddle the boundary between the two adjacent members such as the base and the pillar wood, and further inserting the locking pin from the surface of the member toward the locking hole. The locking flange is brought into contact with the bottom surface of one of the members. As a result, the retaining strength is increased and excellent seismic strength is exhibited.

特許文献２では、部材の破損や変形を防ぐことのできる接合金物が開示されている。この接合金物は、丸棒状または帯状の杵材で構成され、この杵材を二部材の境界を跨ぐように埋め込み、個々の部材の表面から杵材に向けてピンを差し込むことで二部材を接合する。そのため杵材には、ピンを挿通させるための貫通部を複数設けてあるが、この貫通部は、杵材の中心軸から両側へ交互に変位して設けてある。このように貫通部を千鳥足状に並べることで、部材に強い引き抜き荷重が作用した際も、部材の破損や変形などを防ぐことができる。さらにこの文献の各図には、杵材の一端にツバ状の座板を設けることが開示されている。 Patent Document 2 discloses a metal joint that can prevent breakage and deformation of members. This joining hardware is composed of a round bar-shaped or strip-shaped pestle material, and the pestle material is embedded so as to straddle the boundary between the two members, and the two members are joined by inserting a pin from the surface of each member toward the pestle material. do. Therefore, the pestle material is provided with a plurality of penetrating portions for inserting pins, and the penetrating portions are alternately displaced from the central axis of the pestle material to both sides. By arranging the penetrating portions in a staggered pattern in this way, it is possible to prevent the member from being damaged or deformed even when a strong pulling load is applied to the member. Further, each figure of this document discloses that a brim-shaped seat plate is provided at one end of the pestle material.

部材同士を一体化するために各種金物を用いる場合、現地での作業量を削減するため、製材段階で部材に金物を組み込むことがある。その際は、連結される二部材のうち、一方の部材だけに金物を組み込むため、部材の表面から金物が大きく突出することがある。その結果、占有空間が大きくなり、輸送や保管の際の効率が低下するほか、突出する金物との接触で不慮の事故を招く恐れもある。特にＣＬＴなどの集成材を用いた大形の部材は、金物も大形化するため、部材からの突出も大きくなりやすい。 When various hardware is used to integrate the members, the hardware may be incorporated into the member at the sawing stage in order to reduce the amount of work on site. In that case, since the hardware is incorporated in only one of the two members to be connected, the hardware may greatly protrude from the surface of the member. As a result, the occupied space becomes large, the efficiency of transportation and storage decreases, and there is a risk of accidental accidents due to contact with protruding hardware. In particular, a large member using laminated lumber such as CLT tends to have a large protrusion from the member because the hardware is also enlarged.

ＣＬＴは十分な厚さを有するため、そのままで構造材として使用することができ、ＣＬＴを水平に敷設すると、それが床材になり、また直立させると壁材になり、このような床材や壁材を各種金物で一体化するだけで構造物の骨格が完成する。その際は、上下に配置された壁材の間に床材が挟み込まれることになるが、壁材に作用する垂直荷重により、床材の上面や下面が徐々に陥没して骨格構造にゆがみを生じ、様々な不具合を招く恐れがある。なお木材は、繊維方向に沿う圧縮荷重に対しては変形を生じにくいが、繊維方向に対して直交する圧縮荷重に対しては変形を生じやすい。そのため前記の壁材は、垂直荷重による影響を受けにくいが、水平に展開する床材については、変形を生じやすい。 Since CLT has sufficient thickness, it can be used as a structural material as it is. When CLT is laid horizontally, it becomes a flooring material, and when it is erected upright, it becomes a wall material. The skeleton of the structure is completed simply by integrating the wall materials with various hardware. In that case, the floor material will be sandwiched between the wall materials arranged above and below, but the vertical load acting on the wall material will gradually sink the upper and lower surfaces of the floor material and distort the skeletal structure. It may occur and cause various problems. It should be noted that wood is unlikely to be deformed by a compression load along the fiber direction, but is likely to be deformed by a compression load orthogonal to the fiber direction. Therefore, the wall material is not easily affected by the vertical load, but the floor material that expands horizontally is likely to be deformed.

本発明はこうした実情を基に開発されたもので、隣接する部材同士を一体化するために用い、据え付けの前段階において部材からの突出を抑制可能で、また部材の表面の陥没を防ぐことのできる連結構造の提供を目的としている。 The present invention has been developed based on such a situation, and is used to integrate adjacent members, can suppress protrusion from the members in the pre-installation stage, and prevent the surface of the members from collapsing. The purpose is to provide a connection structure that can be used.

前記の課題を解決するための請求項１記載の発明は、隣接する一方材と他方材を一体化するために用いる連結構造であって、基本軸と接続軸とワッシャと固定ピンとを用い、前記基本軸および前記接続軸は円断面の棒状であり、該基本軸の端部は該接続軸を緩みなく収容可能な筒状としてあり、前記ワッシャは該接続軸に緩みなく差し込み可能としてあり、前記基本軸は前記一方材に埋め込み、前記接続軸は前記他方材に埋め込み、且つ該接続軸の一端側は該一方材に向けて突出させてあり、また前記ワッシャは該接続軸に差し込み且つ該一方材と該他方材との境界に挟み込み、前記基本軸および前記接続軸の側周面には貫通穴を設けてあり、前記一方材および前記他方材の表面から該貫通穴に向けて前記固定ピンを差し込むことで該基本軸および該接続軸が固定され、前記他方材から突出する前記接続軸が前記基本軸の内部に入り込み、同心に揃う双方の前記貫通穴を前記固定ピンが貫くことで前記一方材と該他方材が一体化し、前記ワッシャが前記基本軸の端面に接触することで、前記一方材と前記他方材との境界面に作用する圧縮荷重を軽減可能であることを特徴とする連結構造である。 The invention according to claim 1 for solving the above-mentioned problems is a connecting structure used for integrating an adjacent one material and the other material, and uses a basic shaft, a connecting shaft, a washer, and a fixing pin. The basic shaft and the connecting shaft are rod-shaped with a circular cross section, the end of the basic shaft has a cylindrical shape that can accommodate the connecting shaft without loosening, and the washer can be inserted into the connecting shaft without loosening. The basic shaft is embedded in the one material, the connecting shaft is embedded in the other material, and one end side of the connecting shaft is projected toward the one material, and the washer is inserted into the connecting shaft and the one end. It is sandwiched between the material and the other material, and through holes are provided on the side peripheral surfaces of the basic shaft and the connection shaft, and the fixing pin is provided from the surface of the one material and the other material toward the through hole. The basic shaft and the connecting shaft are fixed by inserting the The one material and the other material are integrated, and the washer comes into contact with the end surface of the basic shaft, whereby the compressive load acting on the interface between the one material and the other material can be reduced. It is a connected structure.

本発明による連結構造は、木造建築を始めとする各種の木造構造物において、一方材および他方材と称する部材同士を一体化するためのもので、一方材と他方材は、双方の表面が面接触するものとする。そして本発明による連結構造は、基本軸と接続軸とワッシャと固定ピンの四種類の金属部品を用いている。なお一方材および他方材は、木材であることを前提とするが、ＣＬＴなどの集成材を用いることが多い。 The connecting structure according to the present invention is for integrating members called one-sided material and the other-sided material in various wooden structures such as wooden buildings, and the surface of both the one-sided material and the other-sided material is a surface. Shall be in contact. The connecting structure according to the present invention uses four types of metal parts: a basic shaft, a connecting shaft, a washer, and a fixing pin. It is assumed that the one-sided material and the other-sided material are wood, but laminated lumber such as CLT is often used.

基本軸は、円断面の棒状で一方材に埋め込む。そのため一方材には、基本軸を緩みなく埋め込むための穴をあらかじめ加工しておく。そして基本軸を一方材に固定するため、一方材の表面から基本軸に向けて固定ピンを差し込む。そのため基本軸の側周面には、固定ピンを通すための貫通穴を設ける。貫通穴は、基本軸の軸線方向に沿って複数設けてあり、基本軸は複数本の固定ピンで固定される。また基本軸の端部は、接続軸を収容するため中空状にする必要がある。さらに基本軸を一方材に固定する際は、基本軸の端面が一方材の表面付近に揃うよう、事前に関係箇所の寸法を調整しておく。 The basic shaft is a rod with a circular cross section and is embedded in one material. Therefore, in the one-sided material, a hole for embedding the basic shaft without looseness is pre-processed. Then, in order to fix the basic shaft to one material, a fixing pin is inserted from the surface of the one material toward the basic shaft. Therefore, a through hole for passing the fixing pin is provided on the side peripheral surface of the basic shaft. A plurality of through holes are provided along the axial direction of the basic shaft, and the basic shaft is fixed by a plurality of fixing pins. Further, the end of the basic shaft needs to be hollow to accommodate the connecting shaft. Furthermore, when fixing the basic shaft to one material, adjust the dimensions of the relevant parts in advance so that the end faces of the basic shaft are aligned near the surface of the one material.

接続軸は、丸棒状で他方材に埋め込むが、接続軸については、中空状である必要はない。そして他方材には、接続軸を緩みなく埋め込むための穴をあらかじめ加工しておき、他方材の表面から接続軸に向けて固定ピンを差し込む。そのため接続軸の側周面には、基本軸と同様、貫通穴を設ける。貫通穴は、接続軸の軸線方向に沿って複数設けてあり、接続軸は複数本の固定ピンで固定される。加えて接続軸は、その全体が他方材に埋め込まれる訳ではなく、その一端側は他方材から突出しており、その突出した範囲についても貫通穴が存在するものとする。 The connecting shaft is round and embedded in the other material, but the connecting shaft does not have to be hollow. Then, a hole for embedding the connecting shaft without looseness is formed in the other material in advance, and a fixing pin is inserted from the surface of the other material toward the connecting shaft. Therefore, as with the basic shaft, a through hole is provided on the side peripheral surface of the connecting shaft. A plurality of through holes are provided along the axial direction of the connecting shaft, and the connecting shaft is fixed by a plurality of fixing pins. In addition, it is assumed that the connecting shaft is not entirely embedded in the other material, one end side thereof protrudes from the other material, and a through hole exists also in the protruding range.

一方材と他方材を一体化する際は、他方材から突出する接続軸を一方材側の基本軸の内部に差し込み、さらに同心で並んだ基本軸と接続軸を貫くように固定ピンを差し込む。その結果、基本軸と接続軸が一体化し、基本軸と接続軸を介して一方材と他方材が一体化する。なお、基本軸と接続軸を貫くように固定ピンを差し込むため、双方の貫通穴の位置を調整する必要があるほか、基本軸や接続軸の埋め込み位置もあらかじめ調整する必要がある。 When integrating the one material and the other material, the connecting shaft protruding from the other material is inserted into the inside of the basic shaft on the one side, and the fixing pin is inserted so as to penetrate the concentric basic shaft and the connecting shaft. As a result, the basic shaft and the connecting shaft are integrated, and one material and the other material are integrated via the basic shaft and the connecting shaft. Since the fixing pin is inserted so as to penetrate the basic shaft and the connecting shaft, it is necessary to adjust the positions of the through holes on both sides, and it is also necessary to adjust the embedding position of the basic shaft and the connecting shaft in advance.

ワッシャは、汎用のものと同様、内部が切り抜かれた円盤状で、接続軸に差し込んだ上、一方材と他方材との境界に挟み込むように配置する。なおワッシャは一定の厚さを有するため、一方材または他方材のいずれかの表面には、ワッシャを収容するための丸溝などを加工する。当然ながらこの丸溝は、下穴と同心に揃う。 Like the general-purpose washer, the washer has a disk shape with the inside cut out, and is inserted into the connecting shaft and placed so as to be sandwiched between one material and the other material. Since the washer has a certain thickness, a round groove or the like for accommodating the washer is processed on the surface of either one material or the other material. Naturally, this round groove is concentric with the pilot hole.

さらにワッシャの内径は、接続軸の外径よりもわずかに大きくしておき、ワッシャは、接続軸の側周面に沿って無理なく移動可能とする。その結果、基本軸と接続軸が一体化した状態において、ワッシャは基本軸の端面に接触し、その移動が規制される。したがって、他方材が一方材を押圧する荷重は、ワッシャを介して基本軸でも受け止められ、基本軸を貫く固定ピンを介し、他方材から離れた位置に分散して伝達され、一方材と他方材との境界に作用する荷重が緩和される。 Further, the inner diameter of the washer is made slightly larger than the outer diameter of the connecting shaft so that the washer can move comfortably along the side peripheral surface of the connecting shaft. As a result, in the state where the basic shaft and the connecting shaft are integrated, the washer comes into contact with the end face of the basic shaft, and its movement is restricted. Therefore, the load of the other material pressing the one material is also received by the basic shaft via the washer, and is distributed and transmitted to a position away from the other material via the fixing pin penetrating the basic shaft, and the one material and the other material are transmitted. The load acting on the boundary with is relaxed.

このように、一方材と他方材を一体化する連結構造として、基本軸と接続軸とワッシャと固定ピンの四種類の金属部品を用い、接続軸の一端側を基本軸の内部に差し込み、双方を固定ピンで一体化することで、基本軸の全体を一方材の内部に埋め込み可能で、接続軸についても、一箇所の貫通穴を露出できればよく、これらを各部材に組み込んだ後も占有空間が極端に増大することはなく、輸送や保管に大きな影響を与えることがない。また接続軸にワッシャを差し込み、ワッシャを一方材と他方材との境界に配置するほか、ワッシャを基本軸の端面に接触させることで、一方材と他方材との境界に作用する荷重が緩和され、経年による陥没などを防ぐことができる。 In this way, as a connecting structure that integrates one material and the other material, four types of metal parts, the basic shaft, the connecting shaft, the washer, and the fixing pin, are used, and one end side of the connecting shaft is inserted into the inside of the basic shaft, and both are used. By integrating with a fixing pin, the entire basic shaft can be embedded inside one material, and the connecting shaft only needs to be able to expose one through hole, and the occupied space even after incorporating these into each member. Does not increase significantly and does not significantly affect transportation or storage. In addition, by inserting a washer into the connecting shaft and arranging the washer at the boundary between one material and the other material, and by bringing the washer into contact with the end face of the basic shaft, the load acting on the boundary between one material and the other material is alleviated. , It is possible to prevent depression due to aging.

請求項２記載の発明は、中間階での床材の据え付けなどを考慮したもので、一方材の対向面を挟み込むように他方材を配置してあり、接続軸およびワッシャは、基本軸の両端側に配置してあり、双方の他方材が一方材と一体化していることを特徴とする。建物の中間階などでは、床材の上下両面に壁材が配置されており、これらをまとめて一体化したい場合がある。この発明は、このような状況を想定したもので、一本の基本軸の両端側に接続軸とワッシャを配置するものである。 The invention according to claim 2 takes into consideration the installation of the flooring material on the intermediate floor, the other material is arranged so as to sandwich the facing surface of the one material, and the connecting shaft and the washer are both ends of the basic shaft. It is arranged on the side and is characterized in that the other material of both is integrated with the one material. On the middle floor of a building, wall materials are placed on both the upper and lower sides of the floor material, and it may be desirable to integrate these together. The present invention assumes such a situation, and arranges a connecting shaft and a washer on both ends of one basic shaft.

ここで用いる基本軸は、必然的に一方材の厚さに相当する長さとなり、一方材の内部に全体が埋め込まれる。また接続軸は、個々の他方材の表面から突出しており、この突出している部分を基本軸の内部に差し込んだ後、これまでと同様、一方材の表面から固定ピンを差し込む。そしてこの固定ピンが基本軸と接続軸を一括して貫くことで、中央の一方材と両側の他方材が一体化する。 The basic shaft used here inevitably has a length corresponding to the thickness of one material, and the whole is embedded inside the one material. Further, the connecting shaft protrudes from the surface of each other material, and after inserting the protruding portion into the inside of the basic shaft, the fixing pin is inserted from the surface of the other material as before. Then, when this fixing pin penetrates the basic shaft and the connecting shaft together, one material in the center and the other material on both sides are integrated.

請求項１記載の発明のように、一方材と他方材を一体化する連結構造として、基本軸と接続軸とワッシャと固定ピンの四種類の金属部品を用い、接続軸の一端側を基本軸の内部に差し込み、双方を固定ピンで一体化することで、一方材と他方材との連結が完了する。そして基本軸は、その全体を一方材の内部に埋め込み可能で、接続軸についても一箇所の貫通穴を露出できればよい。そのため、他方材に接続軸を組み込んだ際も、他方材からの突出を抑制可能で、占有空間が極端に増大することはなく、輸送や保管に与える影響を最小限に留めることができる。 As in the invention according to claim 1, four types of metal parts, a basic shaft, a connecting shaft, a washer, and a fixing pin, are used as a connecting structure for integrating one material and the other material, and one end side of the connecting shaft is the basic shaft. By inserting it into the inside of the and integrating both with a fixing pin, the connection between one material and the other material is completed. The entire basic shaft can be embedded inside one of the materials, and the connecting shaft also needs to be able to expose one through hole. Therefore, even when the connecting shaft is incorporated in the other material, the protrusion from the other material can be suppressed, the occupied space does not increase extremely, and the influence on transportation and storage can be minimized.

加えて、接続軸にワッシャを差し込み、ワッシャを一方材と他方材との境界に配置するほか、ワッシャを基本軸の端面に接触させることで、他方材が一方材を押圧する荷重は、ワッシャで受け止められ、その荷重は、基本軸を貫く固定ピンによって広い範囲に分散して伝達される。その結果、一方材と他方材との境界に作用する荷重が緩和され、経年による一方材の表面の陥没などを防ぐことができる。 In addition, by inserting a washer into the connecting shaft and arranging the washer at the boundary between one material and the other material, and by bringing the washer into contact with the end face of the basic shaft, the load that the other material presses on one material is the washer. It is received and its load is distributed and transmitted over a wide range by fixing pins that penetrate the basic shaft. As a result, the load acting on the boundary between the one material and the other material is relaxed, and it is possible to prevent the surface of the one material from being depressed due to aging.

請求項２記載の発明のように、接続軸およびワッシャは、基本軸の両端側に配置することで、建物の中間階など、床材の上下両面に壁材が配置される場合においても、これらをまとめて一体化することができる。なおここで用いる基本軸は、必然的に一方材の厚さと同等の長さになり、一方材の表面から突出することはなく、輸送や保管に影響を与えることはない。 By arranging the connecting shaft and the washer on both ends of the basic shaft as in the invention of claim 2, even when the wall material is arranged on both the upper and lower sides of the floor material such as the middle floor of the building, these Can be integrated together. The basic shaft used here inevitably has a length equivalent to the thickness of the one-sided material, does not protrude from the surface of the one-sided material, and does not affect transportation or storage.

図１は、本発明による連結構造の形状例を示しており、上下に配置された他方材７１で一方材６１を挟み込み、これらを基本軸１１や接続軸２１などの部品で一体化する。なお一方材６１は、平面状に展開する床材を想定しており、他方材７１は、直立する壁材を想定しており、いずれともＣＬＴなど、相応の厚さを有する木材を用いており、これらがそのままの状態で建物などの構造材として機能する。そして図１では、一方材６１の外縁に沿って他方材７１を配置し、それぞれの一側面が段差なく並ぶ。 FIG. 1 shows a shape example of a connecting structure according to the present invention, in which one material 61 is sandwiched between the other materials 71 arranged above and below, and these are integrated by parts such as a basic shaft 11 and a connecting shaft 21. The one-sided material 61 is assumed to be a flooring material developed in a plane, and the other-sided material 71 is assumed to be an upright wall material, both of which are made of wood having an appropriate thickness such as CLT. , These function as structural materials such as buildings as they are. Then, in FIG. 1, the other material 71 is arranged along the outer edge of the one material 61, and one side surface of each is arranged without a step.

この連結構造は、一方材６１に埋め込む基本軸１１と、それぞれの他方材７１に埋め込む接続軸２１と、基本軸１１や接続軸２１を固定する固定ピン４１、４２と、接続軸２１に差し込むワッシャ３１と、を用いている。そのうち基本軸１１は、単純な円断面の中空状であり、一方材６１に埋め込むため、一方材６１の厚さと同じ長さとしてある。また基本軸１１の側周面には、固定ピン４１、４２を差し込むための貫通穴１４、１５を設けてある。当然ながら貫通穴１４、１５は、基本軸１１の中心を挟み込むように両側周面に配置してある。 This connecting structure includes a basic shaft 11 embedded in one material 61, a connecting shaft 21 embedded in each other material 71, fixing pins 41 and 42 for fixing the basic shaft 11 and the connecting shaft 21, and a washer inserted into the connecting shaft 21. 31 and are used. Among them, the basic shaft 11 has a hollow shape with a simple circular cross section and is embedded in the one-sided material 61, so that the length is the same as the thickness of the one-sided material 61. Further, through holes 14 and 15 for inserting the fixing pins 41 and 42 are provided on the side peripheral surface of the basic shaft 11. As a matter of course, the through holes 14 and 15 are arranged on both peripheral surfaces so as to sandwich the center of the basic shaft 11.

一方材６１には、基本軸１１を緩みなく差し込むため、上下面を貫くホゾ穴６３を加工してあり、さらに固定ピン４１、４２を差し込むためのピン穴６４、６５を加工してある。ピン穴６４、６５は、一方材６１の側端面から水平に伸びており、途中でホゾ穴６３と交差しているほか、基本軸１１の貫通穴１４、１５に応じて配置してある。なお図１では、基本軸１１の側周面に上下三箇所の貫通穴１４、１５を描いてあるが、これらは配置が異なるだけで内径などに差はない。 On the other hand, in order to insert the basic shaft 11 into the material 61 without looseness, a hozo hole 63 penetrating the upper and lower surfaces is machined, and further, pin holes 64 and 65 for inserting the fixing pins 41 and 42 are machined. The pin holes 64 and 65 extend horizontally from the side end surface of the one-sided member 61, intersect with the hozo hole 63 on the way, and are arranged according to the through holes 14 and 15 of the basic shaft 11. In FIG. 1, three through holes 14 and 15 are drawn on the side peripheral surface of the basic shaft 11, but these are only different in arrangement and have no difference in inner diameter or the like.

接続軸２１は丸棒状であり、上下の他方材７１のそれぞれに一本埋め込むため、ここでは二本用いているが、いずれとも形状は同じである。また接続軸２１についても、その側周面には、固定ピン４１、４２を差し込むための貫通穴２４、２５を設けてある。そして他方材７１には、接続軸２１を緩みなく差し込むためのホゾ穴７３を加工してあるが、上方に位置する他方材７１については、その下端面から上向きにホゾ穴７３を加工してある。対して下方に位置する他方材７１については、その上端面から下向きにホゾ穴７３を加工してある。加えて他方材７１には、固定ピン４２を差し込むためのピン穴７５を加工してある。ピン穴７５は、他方材７１の側面から水平に伸びており、途中でホゾ穴７３と交差して反対面に到達しているほか、接続軸２１の貫通穴２５に応じて配置してある。 Since the connecting shaft 21 has a round bar shape and one is embedded in each of the upper and lower other materials 71, two are used here, but both have the same shape. Further, the connecting shaft 21 is also provided with through holes 24 and 25 for inserting the fixing pins 41 and 42 on its side peripheral surface. The other material 71 is machined with a hozo hole 73 for inserting the connecting shaft 21 without looseness, but the other material 71 located above is machined with a hozo hole 73 upward from the lower end surface thereof. .. On the other hand, with respect to the other material 71 located below, the hozo hole 73 is machined downward from the upper end surface thereof. In addition, the other material 71 is machined with a pin hole 75 for inserting the fixing pin 42. The pin hole 75 extends horizontally from the side surface of the other material 71, intersects the hozo hole 73 on the way, reaches the opposite surface, and is arranged according to the through hole 25 of the connecting shaft 21.

他方材７１に加工したホゾ穴７３は上下とも有底であり、そこに所定の深さまで接続軸２１を差し込み、貫通穴２５とピン穴７５を同心に揃えた状態において、接続軸２１の一端側は他方材７１から突出する。そしてこの突出した接続軸２１は、一方材６１に埋め込まれた基本軸１１の内部に差し込み、基本軸１１の貫通穴１４と接続軸２１の貫通穴２４を同心に揃えた後、双方を貫くように固定ピン４１を差し込むと、固定ピン４１を介して基本軸１１と接続軸２１が一体化する。したがって接続軸２１については、他方材７１から突出する範囲に貫通穴２４を設けてある。 On the other hand, the hozo hole 73 processed into the material 71 is bottomed both above and below, and the connection shaft 21 is inserted there to a predetermined depth, and in a state where the through hole 25 and the pin hole 75 are concentrically aligned, one end side of the connection shaft 21 is provided. Projects from the other material 71. Then, the protruding connecting shaft 21 is inserted into the inside of the basic shaft 11 embedded in the one-sided member 61, and the through hole 14 of the basic shaft 11 and the through hole 24 of the connecting shaft 21 are concentrically aligned and then penetrate both of them. When the fixing pin 41 is inserted into the fixing pin 41, the basic shaft 11 and the connecting shaft 21 are integrated via the fixing pin 41. Therefore, the connection shaft 21 is provided with a through hole 24 in a range protruding from the other material 71.

ワッシャ３１は、単純な円盤状で接続軸２１に差し込むが、その内径は、接続軸２１の外径よりもわずかに大きく、接続軸２１に対して自在に移動可能である。また一方材６１と他方材７１との境界には、ワッシャ３１を収容するための丸溝７７を加工してある。図の丸溝７７は、他方材７１に加工してあり、ホゾ穴７３と同心に揃っている。なおワッシャ３１は、単に一方材６１と他方材７１との境界に収容される訳ではなく、ワッシャ３１は、他方材７１のほか基本軸１１の端面にも接触させ、荷重を伝達する役割を担う。 The washer 31 has a simple disk shape and is inserted into the connecting shaft 21, but its inner diameter is slightly larger than the outer diameter of the connecting shaft 21 and can be freely moved with respect to the connecting shaft 21. Further, a round groove 77 for accommodating the washer 31 is processed at the boundary between the one-sided material 61 and the other-sided material 71. The round groove 77 in the figure is processed into the other material 71, and is concentrically aligned with the hozo hole 73. The washer 31 is not simply housed at the boundary between the one material 61 and the other material 71, and the washer 31 plays a role of transmitting the load by contacting the other material 71 as well as the end face of the basic shaft 11. ..

図２は、図１に描いた各部品の詳細形状を示しているが、基本軸１１とワッシャ３１は半割の状態を描いてある。ここでは、基本軸１１を上下から挟み込むように接続軸２１とワッシャ３１を配置してあり、ワッシャ３１は接続軸２１に差し込まれるが、基本軸１１の端面に接触することで移動が規制される。また中空状の基本軸１１の側周面には、上下方向に三列の貫通穴１４、１５が並んでいる。そのほか接続軸２１の一端側は、基本軸１１の内部に入り込むほか、個々の接続軸２１には、上下方向に三列の貫通穴２４、２５が並んでいる。 FIG. 2 shows the detailed shape of each part drawn in FIG. 1, but the basic shaft 11 and the washer 31 are drawn in half. Here, the connecting shaft 21 and the washer 31 are arranged so as to sandwich the basic shaft 11 from above and below, and the washer 31 is inserted into the connecting shaft 21, but the movement is restricted by contacting the end surface of the basic shaft 11. .. Further, on the side peripheral surface of the hollow basic shaft 11, three rows of through holes 14 and 15 are arranged in the vertical direction. In addition, one end side of the connecting shaft 21 enters the inside of the basic shaft 11, and the individual connecting shafts 21 are lined with three rows of through holes 24 and 25 in the vertical direction.

個々の接続軸２１において、基本軸１１に一番近い側の貫通穴２４は、基本軸１１の内部に入り込み、この貫通穴２４は、基本軸１１の端部近傍に設けた貫通穴１４と同心に揃え、そこに固定ピン４１を差し込むことで、基本軸１１と接続軸２１が一体化する。また基本軸１１を一方材６１に埋め込んだ後、基本軸１１の中央に位置する貫通穴１５に固定ピン４２を差し込むと、基本軸１１が一方材６１に固定される。同様に、接続軸２１を他方材７１に埋め込んだ後、接続軸２１の貫通穴２５に固定ピン４２を差し込むと、接続軸２１が他方材７１に固定される。 In each connection shaft 21, the through hole 24 on the side closest to the basic shaft 11 enters the inside of the basic shaft 11, and the through hole 24 is concentric with the through hole 14 provided near the end of the basic shaft 11. The basic shaft 11 and the connecting shaft 21 are integrated by aligning them with the fixing pin 41 and inserting the fixing pin 41 into the fixing pin 41. Further, when the fixing pin 42 is inserted into the through hole 15 located at the center of the basic shaft 11 after the basic shaft 11 is embedded in the one-sided material 61, the basic shaft 11 is fixed to the one-sided material 61. Similarly, when the connecting shaft 21 is embedded in the other material 71 and then the fixing pin 42 is inserted into the through hole 25 of the connecting shaft 21, the connecting shaft 21 is fixed in the other material 71.

図３は、図１の一方材６１に基本軸１１を組み込み、他方材７１に接続軸２１を組み込んだ状態を示す。基本軸１１は、一方材６１の内部に完全に埋め込まれており、外部には一切突出していない。そして基本軸１１の中央付近には、固定ピン４２が差し込まれており、基本軸１１は一方材６１に固定されている。なおこの段階においては、一方材６１の上下面近傍のピン穴６４には、固定ピン４１を差し込むことができない。 FIG. 3 shows a state in which the basic shaft 11 is incorporated in one material 61 of FIG. 1 and the connecting shaft 21 is incorporated in the other material 71. The basic shaft 11 is completely embedded inside the one-sided material 61 and does not project to the outside at all. A fixing pin 42 is inserted near the center of the basic shaft 11, and the basic shaft 11 is fixed to the one-sided member 61. At this stage, the fixing pin 41 cannot be inserted into the pin hole 64 near the upper and lower surfaces of the one-sided material 61.

他方材７１については、そのホゾ穴７３に接続軸２１が差し込まれており、さらに接続軸２１と交差するように固定ピン４２を差し込んであり、接続軸２１は他方材７１に固定されている。この状態において、他方材７１から接続軸２１の一端側が突出しており、これを基本軸１１の内部に入り込ませる。また突出する接続軸２１にはワッシャ３１を差し込んであり、これが他方材７１に加工した丸溝７７に収容されている。この図のように、基本軸１１や接続軸２１の組み込みは製材段階で実施可能で、現地での作業を簡素化できる。 As for the other material 71, the connecting shaft 21 is inserted into the hozo hole 73, and the fixing pin 42 is further inserted so as to intersect the connecting shaft 21, and the connecting shaft 21 is fixed to the other material 71. In this state, one end side of the connecting shaft 21 protrudes from the other material 71, and this is inserted into the inside of the basic shaft 11. Further, a washer 31 is inserted into the protruding connecting shaft 21, which is accommodated in a round groove 77 processed into the other material 71. As shown in this figure, the basic shaft 11 and the connecting shaft 21 can be incorporated at the sawing stage, and the on-site work can be simplified.

図３の後、突出する接続軸２１を基本軸１１の内部に入り込ませ、上下の他方材７１を一方材６１に接触させる。さらに同心で並ぶ基本軸１１と接続軸２１を貫くように固定ピン４１を差し込むと、基本軸１１と接続軸２１を介して一方材６１と他方材７１が一体化される。本発明では、従来のホゾパイプに相当する部品を基本軸１１と接続軸２１の二要素に分割し、これらを固定ピン４１で一体化する方式のため、基本軸１１や接続軸２１を部材に組み込んだ後も、部材からの突出を抑制できる。なおホゾ穴６３、７３やピン穴６４、６５、７５は、設計図面などに基づき、所定の位置に加工する必要がある。 After FIG. 3, the protruding connecting shaft 21 is inserted into the inside of the basic shaft 11, and the upper and lower other materials 71 are brought into contact with the one material 61. Further, when the fixing pin 41 is inserted so as to penetrate the basic shaft 11 and the connecting shaft 21 arranged concentrically, the one material 61 and the other material 71 are integrated via the basic shaft 11 and the connecting shaft 21. In the present invention, the component corresponding to the conventional hozopipe is divided into two elements, the basic shaft 11 and the connecting shaft 21, and these are integrated by the fixing pin 41. Therefore, the basic shaft 11 and the connecting shaft 21 are incorporated into the member. Even after that, the protrusion from the member can be suppressed. The hozo holes 63, 73 and the pin holes 64, 65, 75 need to be machined at predetermined positions based on design drawings and the like.

図４は、図１の一方材６１と他方材７１を一体化した状態を示す。他方材７１に埋め込まれた接続軸２１の一端側は、一方材６１に埋め込まれた基本軸１１の内部に入り込んでおり、一方材６１のピン穴６４から固定ピン４１を差し込むと、基本軸１１と接続軸２１が一体化し、必然的に一方材６１と他方材７１も一体化される。なお一方材６１は、水平に展開する広大な床材であり、また他方材７１は、直立する広大な壁材であり、必要な強度を確保するため、連結構造は所定の間隔で複数配置することが多い。 FIG. 4 shows a state in which one material 61 and the other material 71 of FIG. 1 are integrated. One end side of the connecting shaft 21 embedded in the other material 71 is inserted inside the basic shaft 11 embedded in the one material 61, and when the fixing pin 41 is inserted from the pin hole 64 of the one material 61, the basic shaft 11 is inserted. And the connecting shaft 21 are integrated, and inevitably, the one-sided material 61 and the other-sided material 71 are also integrated. The one lumber 61 is a vast flooring material that expands horizontally, and the other lumber 71 is a vast upright wall material. In order to secure the required strength, a plurality of connecting structures are arranged at predetermined intervals. Often.

一方材６１と他方材７１との境界には、ワッシャ３１が挟み込まれており、しかもワッシャ３１は基本軸１１の端面に接触している。そのため、他方材７１が一方材６１を押圧する荷重の一部は、ワッシャ３１を介して基本軸１１に伝達していき、一方材６１の上下面に作用する荷重が緩和され、経年による一方材６１の変形などを抑制可能である。 A washer 31 is sandwiched between the one-side material 61 and the other-side material 71, and the washer 31 is in contact with the end face of the basic shaft 11. Therefore, a part of the load that the other material 71 presses on the one material 61 is transmitted to the basic shaft 11 via the washer 31, and the load acting on the upper and lower surfaces of the one material 61 is relaxed, and the one material due to aging. It is possible to suppress deformation of 61 and the like.

図５は、隣接する二部材を一体化する場合を示す斜視図で、二部材のうちの一方材６１は直立する壁材で、また他方材７１は水平に展開する床材である。本発明による連結構造は、この図のように二部材だけを一体化する場合にも使用可能で、ここでは一方材６１に基本軸１１を埋め込み、他方材７１に接続軸２１を埋め込んでいるが、接続軸２１の上端部が突出しており、これが基本軸１１の内部に入り込む。そして、一方材６１の側面から固定ピン４１を差し込み、これが同心で並ぶ基本軸１１と接続軸２１を貫くことで基本軸１１と接続軸２１が一体化し、一方材６１と他方材７１も一体化する。なおワッシャ３１についても、これまでの各図と同様、一方材６１と他方材７１との境界に挟み込まれ、さらにワッシャ３１は基本軸１１の端面に接触している。 FIG. 5 is a perspective view showing a case where two adjacent members are integrated. One of the two members, 61, is an upright wall material, and the other member 71 is a horizontally expanding floor material. The connecting structure according to the present invention can also be used when only two members are integrated as shown in this figure. Here, the basic shaft 11 is embedded in one material 61 and the connecting shaft 21 is embedded in the other material 71. , The upper end of the connecting shaft 21 protrudes, and this enters the inside of the basic shaft 11. Then, by inserting the fixing pin 41 from the side surface of the one-sided material 61 and penetrating the basic shaft 11 and the connecting shaft 21 which are concentrically arranged, the basic shaft 11 and the connecting shaft 21 are integrated, and the one-sided material 61 and the other material 71 are also integrated. do. The washer 31 is also sandwiched between the boundary between the one material 61 and the other material 71 as in the previous drawings, and the washer 31 is in contact with the end surface of the basic shaft 11.

図６は、基本軸１２を分割構造としてあり、突発的な引張荷重を緩和可能としたものを示す。これまでの各図に示すように、基本軸１１は単純な中空状とすることが可能で、製造価格を抑制できる。ただしこの図に描くように、基本軸１２を分割構造とすることで、突発的な引張荷重を緩和可能になり、地震に遭遇した際の安全性を高めることができる。ここでの基本軸１２は、同心で並ぶ二本の細分管１７を結合具５１で一体化した構造で、結合具５１を意図的に引き伸ばすことで突発的な引張荷重が緩和される。 FIG. 6 shows a basic shaft 12 having a divided structure so that a sudden tensile load can be relaxed. As shown in the drawings so far, the basic shaft 11 can be made into a simple hollow shape, and the manufacturing price can be suppressed. However, as shown in this figure, by forming the basic shaft 12 into a split structure, a sudden tensile load can be relaxed, and safety in the event of an earthquake can be enhanced. The basic shaft 12 here has a structure in which two concentric subdivision pipes 17 are integrated by a coupling tool 51, and a sudden tensile load is relaxed by intentionally stretching the coupling tool 51.

細分管１７は円断面の中空状だが、その内部には内径を絞り込んだ箇所を設け、その中心にメネジ１８を設けてある。さらに細分管１７の一端寄りには、固定ピン４１を差し込むための貫通穴１４を設けてある。また結合具５１は、両端にオネジ５２を設けたスタッドボルトであり、その一端側には、回転を規制できるよう、角断面のヘッド５３を設けてある。当然ながら結合具５１は、想定される引張荷重に対して適切な弾塑性変形を生じるよう、素材や断面径を決定する。なお接続軸２２やワッシャ３１についても、これまでの各図と同様に使用する。 The subdivision tube 17 has a hollow circular cross section, but a portion having a narrowed inner diameter is provided inside the subdivision tube 17, and a female screw 18 is provided at the center thereof. Further, a through hole 14 for inserting the fixing pin 41 is provided near one end of the subdivision pipe 17. Further, the coupling tool 51 is a stud bolt provided with male threads 52 at both ends, and a head 53 having a square cross section is provided on one end side thereof so that rotation can be restricted. As a matter of course, the coupler 51 determines the material and the cross-sectional diameter so as to cause appropriate elasto-plastic deformation with respect to the assumed tensile load. The connecting shaft 22 and the washer 31 are also used in the same manner as in the previous drawings.

二本の細分管１７を一体化する際は、図の右寄りに描くように、まず結合具５１の下方に設けたオネジ５２を細分管１７のメネジ１８に螺合させ、オネジ５２の根元がメネジ１８に噛み込んで回転不能になるまで締め付けを行う。次に、結合具５１の上方から残る一方の細分管１７を接近させ、そのメネジ１８を結合具５１上方のオネジ５２に螺合させ、上下の細分管１７が密着して一体化するまで締め付けを行うと、基本軸１２の組み立てが完了する。 When integrating the two subdivision pipes 17, as shown on the right side of the figure, first screw the male screw 52 provided below the fitting 51 into the female screw 18 of the subdivision pipe 17, and the base of the male screw 52 is the female screw. Tighten until it bites into 18 and cannot rotate. Next, one of the subdivision pipes 17 remaining from above the coupler 51 is brought close to each other, and the female screw 18 is screwed into the male screw 52 above the coupler 51, and tightened until the upper and lower subdivision pipes 17 are in close contact with each other and integrated. This completes the assembly of the basic shaft 12.

組み立てが完了した基本軸１２の取り扱いは、これまの各図と同じであり、その端部に接続軸２２を入り込ませ、同心で並ぶ基本軸１２と接続軸２２を貫くように固定ピン４１を差し込み、基本軸１２と接続軸２２を一体化させる。なお図６では、結合具５１との干渉を防ぐため、接続軸２２についても中空状としてある。そのほか細分管１７や結合具５１については、この図の構成に限定される訳ではなく、他にも様々な構成を導入することができる。 The handling of the assembled basic shaft 12 is the same as in each drawing so far. The connecting shaft 22 is inserted into the end thereof, and the fixing pin 41 is inserted so as to penetrate the concentric basic shaft 12 and the connecting shaft 22. Insert it to integrate the basic shaft 12 and the connecting shaft 22. In FIG. 6, the connecting shaft 22 is also hollow in order to prevent interference with the coupling tool 51. In addition, the subdivision tube 17 and the coupling tool 51 are not limited to the configuration shown in this figure, and various other configurations can be introduced.

図７は、図６の基本軸１２を用いて一方材６１と他方材７１を一体化した状態を示す。なおこの図では、内部構造を示すため、一方材６１や他方材７１は縦断面を描いてある。このように、一方材６１には基本軸１２が埋め込まれ、他方材７１には接続軸２２が埋め込まれ、接続軸２２の端部が基本軸１２の内部に入り込み、固定ピン４１によって基本軸１２と接続軸２２が一体化している。そのため、一方材６１が上下の他方材７１で挟み込まれている。しかし、この連結構造に突発的な引張荷重が作用すると、図の右側に描くように、結合具５１が引き伸ばされて一方材６１や他方材７１の破損を防ぐ。このように結合具５１が引き伸ばされる際、一方材６１に差し込まれている固定ピン４１も移動するため、一方材６１が破損する恐れがある。そこでこの固定ピン４１は、短いものを用いるなどの対策を講じることがある。 FIG. 7 shows a state in which one material 61 and the other material 71 are integrated using the basic shaft 12 of FIG. In this figure, in order to show the internal structure, the one-sided material 61 and the other-sided material 71 have vertical cross sections. In this way, the basic shaft 12 is embedded in the one material 61, the connecting shaft 22 is embedded in the other material 71, the end portion of the connecting shaft 22 enters the inside of the basic shaft 12, and the basic shaft 12 is provided by the fixing pin 41. And the connection shaft 22 are integrated. Therefore, the one material 61 is sandwiched between the upper and lower other materials 71. However, when a sudden tensile load acts on this connecting structure, the binder 51 is stretched to prevent damage to the one-sided material 61 and the other-sided material 71, as shown on the right side of the figure. When the binder 51 is stretched in this way, the fixing pin 41 inserted into the one-sided material 61 also moves, so that the one-sided material 61 may be damaged. Therefore, measures such as using a short fixing pin 41 may be taken.

これまでの各図は、本発明による連結構造の構成例の具体例を示すに過ぎず、基本軸１１、１２や接続軸２１、２２を固定する固定ピン４２の本数は、強度などの条件に基づき、自在に決めることができるほか、基本軸１１、１２と接続軸２１、２２を一体化する固定ピン４１についても、強度との兼ね合いで複数本としてもよい。 Each figure so far only shows a specific example of the configuration example of the connecting structure according to the present invention, and the number of fixing pins 42 for fixing the basic shafts 11 and 12 and the connecting shafts 21 and 22 depends on the conditions such as strength. Based on this, it can be freely determined, and the number of fixing pins 41 that integrate the basic shafts 11 and 12 and the connecting shafts 21 and 22 may be multiple in consideration of strength.
