これによると、2つの建材を、複数の連結部材により、2つの建材の間隔の方向と、2つの建材のうちの一方の建材の厚さ方向とに直交する方向に不動状態にして連結することができ、このように不動状態にして2つの建材を連結することができる特許文献1の技術では、それぞれの連結部材の長さ寸法は同じになっている。 According to this, two building materials are steadily connected by a plurality of connecting members in a direction orthogonal to the direction of the distance between the two building materials and the thickness direction of one of the two building materials. In the technique of Patent Document 1, which can connect two building materials in an immovable state in this way, the length and dimension of each connecting member are the same.

本発明の目的は、2つの建材を連結するための複数の連結部材のうち、一部の連結部材の長さ寸法を短縮できて、材料の削減を達成できるようになる建材の連結装置、その連結構造及びその連結方法を提供するところにある。 An object of the present invention is a building material connecting device capable of shortening the length dimension of some of the connecting members for connecting two building materials and achieving a reduction in materials. It is here to provide a connection structure and a connection method thereof.

本発明に係る建材の連結装置は、間隔をあけて配設される2つの建材を連結するために、前記間隔の方向と、前記2つの建材のうちの一方の建材の厚さ方向とに直交する方向に並設され、かつ前記間隔の方向に対する傾きが異なっている複数の連結部材を備えて構成されている建材の連結装置において、前記複数の連結部材には、前記一方の建材に接続された接続部と、前記2つの建材のうちの他方の建材に接続された接続部との間の寸法が大きくなっている第1連結部材と、前記一方の建材に接続された接続部と、前記他方の建材に接続された接続部との間の寸法が小さくなっている第2連結部材とがあり、前記間隔の方向に対する前記第1連結部材の傾き角度が、前記間隔の方向に対する前記第2連結部材の傾き角度よりも大きくなっていることを特徴とするものである。 The building material connecting device according to the present invention is orthogonal to the direction of the spacing and the thickness direction of one of the two building materials in order to connect the two building materials arranged at intervals. In a building material connecting device configured to include a plurality of connecting members arranged side by side in the direction of the building and having different inclinations with respect to the direction of the spacing, the plurality of connecting members are connected to the one building material. The first connecting member having a large dimension between the connecting portion and the connecting portion connected to the other building material of the two building materials, the connecting portion connected to the one building material, and the above. There is a second connecting member having a smaller dimension between the connecting portion connected to the other building material, and the inclination angle of the first connecting member with respect to the direction of the spacing is the second connecting member with respect to the direction of the spacing. It is characterized in that it is larger than the inclination angle of the connecting member.

このため、本発明に係る建材の連結装置において、2つの建材を連結する複数の連結部材には、第1連結部材と第2連結部材があり、2つの建材の間隔の方向に対する第1連結部材の傾き角度は、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくなっているため、2つの建材を、これらの第1連結部材と第2連結部材により、2つの建材の間隔の方向と、2つの建材のうちの一方の建材の厚さ方向とに直交する方向に不動状態にして連結することができ、また、第1連結部材では、2つの建材のうちの一方の建材に接続された接続部と、2つの建材のうちの他方の建材に接続された接続部との間の寸法が大きくなっているが、第2連結部材では、一方の建材に接続された接続部と、他方の建材に接続された接続部との間の寸法が小さくなっているため、この第2連結部材の長さ寸法を第1連結部材の長さ寸法よりも短縮することができ、これにより、材料の削減を達成して2つの建材を連結できるようになる。 Therefore, in the building material connecting device according to the present invention, the plurality of connecting members connecting the two building materials include a first connecting member and a second connecting member, and the first connecting member in the direction of the distance between the two building materials. Since the tilt angle of the two building materials is larger than the tilt angle of the second connecting member with respect to the direction of the distance between the two building materials, the two building materials are separated from the two building materials by the first connecting member and the second connecting member. It can be connected in an immovable state in a direction orthogonal to the direction of the interval and the thickness direction of one of the two building materials, and in the first connecting member, one of the two building materials can be connected. The dimension between the connection part connected to the building material and the connection part connected to the other building material of the two building materials is large, but in the second connecting member, the connection connected to one building material. Since the dimension between the portion and the connecting portion connected to the other building material is small, the length dimension of the second connecting member can be made shorter than the length dimension of the first connecting member. This makes it possible to achieve material reduction and connect the two building materials.

なお、上述のように2つの建材の間隔の方向に対する第1連結部材の傾き角度を、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくすることは、これらの第1連結部材及び第2連結部材についての2つの建材の間隔の方向に対する傾き方向を同じにして行ってもよく、あるいは、2つの建材の間隔の方向に対する傾き方向を互いに逆の方向にして行ってもよく、あるいは、2つの建材の間隔の方向に対する第2連結部材の傾き角度を0度にして行ってもよい。 As described above, making the inclination angle of the first connecting member with respect to the direction of the distance between the two building materials larger than the inclination angle of the second connecting member with respect to the direction of the distance between the two building materials is to make these first connecting members. The tilting direction of the member and the second connecting member with respect to the direction of the spacing between the two building materials may be the same, or the tilting directions of the two building materials with respect to the direction of the spacing may be opposite to each other. Alternatively, the inclination angle of the second connecting member with respect to the direction of the distance between the two building materials may be set to 0 degrees.

また、前述したように第1連結部材では、2つの建材のうちの一方の建材に接続された接続部と、2つの建材のうちの他方の建材に接続された接続部との間の寸法が大きくなっているとともに、第2連結部材では、一方の建材に接続された接続部と、他方の建材に接続された接続部との間の寸法が小さくなっていて、2つの建材の間隔の方向に対する第1連結部材の傾き角度が、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくなっていれば、第1連結部材及び第2連結部材を、任意の形状や構造のものとすることができる。 Further, as described above, in the first connecting member, the dimension between the connecting portion connected to one of the two building materials and the connecting portion connected to the other building material of the two building materials is In addition to being large, in the second connecting member, the dimension between the connection part connected to one building material and the connection part connected to the other building material is small, and the direction of the distance between the two building materials is small. If the tilt angle of the first connecting member with respect to the above is larger than the tilt angle of the second connecting member with respect to the direction of the distance between the two building materials, the first connecting member and the second connecting member can be of any shape or structure. Can be.

その一例は、第1連結部材及び第2連結部材のそれぞれを、細長の板状のものとすることであり、他の例は、第1連結部材と第2連結部材のうち、少なくとも一方の連結部材を、それぞれの長さ方向の両端部が2つの建材に達していて、前記一方の建材の厚さ方向に離れて2個設けられている連結部と、これらの連結部に架け渡されていて、これらの連結部材同士を結合している架け渡し部とを有するものとすることである。 One example is to make each of the first connecting member and the second connecting member into an elongated plate shape, and another example is to connect at least one of the first connecting member and the second connecting member. The members are bridged to two connecting portions having both ends in each length direction reaching two building materials and separated from each other in the thickness direction of one of the building materials. Therefore, it is assumed that it has a bridging portion that connects these connecting members to each other.

これらのうち、後者によると、第1連結部材と第2連結部材のうち、少なくとも一方の連結部材は、それぞれの長さ方向の両端部が2つの建材に達していて、前記一方の建材の厚さ方向に離れている2個の連結部と、これらの連結部に架け渡された架け渡し部とを有するものとなるため、この連結部材の強度は大きくなり、これにより、2つの建材を大きな強度により連結することができるようになる。 Of these, according to the latter, at least one of the first connecting member and the second connecting member has both ends in the length direction reaching two building materials, and the thickness of the one building material is reached. Since it has two connecting portions separated in the vertical direction and a connecting portion bridged over these connecting portions, the strength of this connecting member is increased, thereby increasing the strength of the two building materials. It becomes possible to connect by strength.

また、以上の本発明に係る建材の連結装置において、第1連結部材及び第2連結部材と前記一方の建材とを接続することや、第1連結部材及び第2連結部材と前記他方の建材とを接続することは、任意の接続形式で行うことができ、例えば、溶接によって接続してもよく、あるいは、ビスやリベット等の結合具で接続してもよく、あるいは、第1連結部材及び第2連結部材と前記一方の建材との接続を、溶接と結合具のうちの一方で行い、第1連結部材及び第2連結部材と前記他方の建材との接続を、溶接と結合具のうちの他方で行うようにしてもよい。また、上述の接続を係止や、係合、引っ掛け等により行ってもよい。 Further, in the above-mentioned building material connecting device according to the present invention, connecting the first connecting member and the second connecting member to the one building material, or connecting the first connecting member and the second connecting member to the other building material. Can be connected in any connection form, for example, may be connected by welding, may be connected by a binder such as a screw or a rivet, or may be connected to the first connecting member and the first connecting member. 2 The connection between the connecting member and the one building material is performed in one of the welding and the coupling tool, and the connection between the first connecting member and the second connecting member and the other building material is performed in the welding and the coupling tool. It may be done on the other side. Further, the above-mentioned connection may be made by locking, engaging, hooking or the like.

本発明に係る建材の連結構造は、間隔をあけて配設される2つの建材が、前記間隔の方向と、前記2つの建材のうちの一方の建材の厚さ方向とに直交する方向に並設されている複数の連結部材により連結されているとともに、前記複数の連結部材が、前記間隔の方向に対する傾きが異なって前記2つの建材に架け渡されている建材の連結構造において、前記複数の連結部材には、それぞれの一方の端部が前記一方の建材に接続され、それぞれの他方の端部が前記2つの建材のうちの他方の建材に接続された第1連結部材と第2連結部材とがあり、前記第1連結部材における前記一方の建材と接続された接続部と、前記第1連結部材における前記他方の建材と接続された接続部との間の寸法は、前記第2連結部材における前記一方の建材と接続された接続部と、前記第2連結部材における前記他方の建材と接続された接続部との間の寸法よりも大きくなっており、前記間隔の方向に対する前記第1連結部材の傾き角度が、前記間隔の方向に対する前記第2連結部材の傾き角度よりも大きくなっていることを特徴とするものである。 In the connecting structure of building materials according to the present invention, two building materials arranged at intervals are arranged in a direction orthogonal to the direction of the distance and the thickness direction of one of the two building materials. The plurality of connecting members are connected by a plurality of provided connecting members, and the plurality of connecting members are bridged to the two building materials with different inclinations with respect to the direction of the spacing. In the connecting member, one end of each is connected to the one building material, and the other end of each is connected to the other building material of the two building materials. The dimension between the connecting portion connected to the one building material in the first connecting member and the connecting portion connected to the other building material in the first connecting member is the second connecting member. The dimension is larger than the dimension between the connecting portion connected to the one building material in the above and the connecting portion connected to the other building material in the second connecting member, and the first connection in the direction of the spacing. It is characterized in that the tilt angle of the members is larger than the tilt angle of the second connecting member with respect to the direction of the spacing.

このため、本発明に係る建材の連結構造において、間隔をあけて配設される2つの建材は、2つの建材の間隔の方向と、2つの建材のうちの一方の建材の厚さ方向とに直交する方向に並設されている第1連結部材及び第2連結部材を含む複数の連結部材により連結されているとともに、2つの建材の間隔の方向に対する第1連結部材の傾き角度は、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくなっているため、2つの建材を、これらの第1連結部材と第2連結部材により、2つの建材の間隔の方向と、2つの建材のうちの一方の建材の厚さ方向とに直交する方向に不動状態にして連結することができる。また、第1連結部材における前記一方の建材と接続された接続部と、第1連結部材における前記他方の建材と接続された接続部との間の寸法は、第2連結部材における前記一方の建材と接続された接続部と、第2連結部材における前記他方の建材と接続された接続部との間の寸法よりも大きくなっているため、第1連結部材の長さ寸法よりも第2連結部材の長さ寸法は短くなっており、これにより、第2連結部材の長さ寸法を短縮でき、その分だけ材料の削減を達成して、2つの建材を連結できるようになる。 Therefore, in the connecting structure of building materials according to the present invention, the two building materials arranged at intervals are in the direction of the distance between the two building materials and the thickness direction of one of the two building materials. It is connected by a plurality of connecting members including the first connecting member and the second connecting member arranged side by side in the orthogonal direction, and the inclination angle of the first connecting member with respect to the direction of the distance between the two building materials is two. Since it is larger than the inclination angle of the second connecting member with respect to the direction of the space between the building materials, the two building materials are divided into the direction of the space between the two building materials and the two by the first connecting member and the second connecting member. It can be connected in an immovable state in a direction orthogonal to the thickness direction of one of the building materials. Further, the dimension between the connecting portion connected to the one building material in the first connecting member and the connecting portion connected to the other building material in the first connecting member is the dimension of the one building material in the second connecting member. Since the dimension is larger than the dimension between the connecting portion connected to and the connecting portion connected to the other building material in the second connecting member, the second connecting member is larger than the length dimension of the first connecting member. The length dimension of the second connecting member is shortened, whereby the length dimension of the second connecting member can be shortened, the reduction of materials can be achieved by that amount, and the two building materials can be connected.

この建材の連結構造においても、上述のように2つの建材の間隔の方向に対する第1連結部材の傾き角度を、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくすることは、これらの第1連結部材及び第2連結部材についての2つの建材の間隔の方向に対する傾き方向を同じにして行ってもよく、あるいは、2つの建材の間隔の方向に対する傾き方向を互いに逆の方向にして行ってもよく、あるいは、2つの建材の間隔の方向に対する第2連結部材の傾き角度を0度にして行ってもよい。 Also in this connecting structure of building materials, as described above, the inclination angle of the first connecting member with respect to the direction of the distance between the two building materials may be larger than the inclination angle of the second connecting member with respect to the direction of the distance between the two building materials. , The inclination direction of these first connecting member and the second connecting member with respect to the direction of the distance between the two building materials may be the same, or the inclination directions of the two building materials with respect to the direction of the distance may be opposite to each other. Alternatively, the inclination angle of the second connecting member with respect to the direction of the distance between the two building materials may be set to 0 degrees.

さらに、本発明に係る建材の連結構造においても、第1連結部材及び第2連結部材と前記一方の建材とを接続することや、第1連結部材及び第2連結部材と前記他方の建材とを接続することは、任意の接続形式で行うことができ、例えば、溶接によって接続してもよく、あるいは、ビスやリベット等の結合具で接続してもよく、あるいは、第1連結部材及び第2連結部材と前記一方の建材との接続を、溶接と結合具のうちの一方で行い、第1連結部材及び第2連結部材と前記他方の建材との接続を、溶接と結合具のうちの他方で行うようにしてもよい。また、上述の接続を係止や、係合、引っ掛け等により行ってもよい。 Further, also in the connecting structure of the building material according to the present invention, the first connecting member and the second connecting member are connected to the one building material, and the first connecting member and the second connecting member are connected to the other building material. The connection can be performed in any connection form, for example, it may be connected by welding, it may be connected by a connecting tool such as a screw or a rivet, or the first connecting member and the second connecting member and the second. The connection between the connecting member and the one building material is performed on one of the welding and the coupling tool, and the connection between the first connecting member and the second connecting member and the other building material is performed on the other of the welding and the coupling tool. You may do it at. Further, the above-mentioned connection may be made by locking, engaging, hooking or the like.

また、本発明に係る建材の連結構造において、第1連結部材及び第2連結部材における前記一方の建材と接続された前記接続部を、この一方の建材に設けられた中心軸を中心に第1連結部材及び第2連結部材が回動自在となった回動式接続部としてもよい。 Further, in the connecting structure of the building material according to the present invention, the connecting portion connected to the one building material in the first connecting member and the second connecting member is first connected to the central axis provided in the one building material. A rotary connecting portion in which the connecting member and the second connecting member are rotatable may be used.

そして、このように第1連結部材及び第2連結部材における前記一方の建材と接続された前記接続部を、この一方の建材に設けられた中心軸を中心に第1連結部材及び第2連結部材が回動自在となった回動式接続部とする場合には、第1連結部材及び第2連結部材における前記他方の建材と接続された前記接続部を、第1連結部材及び第2連結部材と前記他方の建材とが結合具により結合された結合式接続部としてもよい。 Then, the connecting portion connected to the one building material in the first connecting member and the second connecting member in this way is connected to the first connecting member and the second connecting member centering on the central axis provided in the one building material. In the case of a rotatable connecting portion in which is rotatable, the connecting portion connected to the other building material in the first connecting member and the second connecting member is replaced with the first connecting member and the second connecting member. It may be a coupling type connecting portion in which the other building material and the other building material are bonded by a coupling tool.

これによると、前記一方の建材と前記他方の建材との間の間隔を調整した後に、第1連結部材及び第2連結部材を回動式接続部を中心に回動させて、これらの第1連結部材及び第2連結部材と前記他方の建材とを前記結合具により結合するという作業を実施することができるようになる。 According to this, after adjusting the distance between the one building material and the other building material, the first connecting member and the second connecting member are rotated around the rotary connecting portion, and the first of these is It becomes possible to carry out the work of connecting the connecting member and the second connecting member to the other building material by the connecting tool.

なお、このように前記一方の建材と前記他方の建材との間の間隔を調整した後に、第1連結部材及び第2連結部材と前記他方の建材とを結合具により結合するための作業を実施できるようにするためには、前記結合具を、第1連結部材及び第2連結部材と前記他方の建材とのうち、少なくとも前記他方の建材をねじ切り孔加工するねじ切り孔加工結合具とすることが好ましい。 After adjusting the distance between the one building material and the other building material in this way, the work for joining the first connecting member and the second connecting member and the other building material with the coupling tool is carried out. In order to be able to do so, the coupling tool may be a threaded hole processing coupling tool for threading at least the other building material among the first connecting member and the second connecting member and the other building material. preferable.

これによると、前記一方の建材と前記他方の建材との間の間隔を調整した後に、上述したように2つの建材の間隔の方向に対する第1連結部材の傾き角度を、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくして、第1連結部材及び第2連結部材を前記他方の建材に接続するための作業を、ねじ切り孔加工結合具によって前記他方の建材の任意の箇所にねじ切り孔加工を行うことによって実施できるようになる。 According to this, after adjusting the distance between the one building material and the other building material, as described above, the inclination angle of the first connecting member with respect to the direction of the distance between the two building materials is set to the distance between the two building materials. The work for connecting the first connecting member and the second connecting member to the other building material by making it larger than the inclination angle of the second connecting member with respect to the direction can be performed by any of the other building materials by a threaded hole processing coupling tool. It can be carried out by drilling a threaded hole in the place.

本発明に係る建材の連結方法は、間隔をあけて配設される2つの建材を、前記間隔の方向と、前記2つの建材のうちの一方の建材の厚さ方向とに直交する方向に並設され、かつ前記間隔の方向に対する傾きが異なっている複数の連結部材により建材の連結方法において、前記複数の連結部材には、前記一方の建材に接続された接続部と、前記2つの建材のうちの他方の建材に接続された接続部との間の寸法が大きくなっている第1連結部材と、前記一方の建材に接続された接続部と、前記他方の建材に接続された接続部との間の寸法が小さくなっている第2連結部材とがあり、前記第1連結部材及び前記第2連結部材における一方の端部を前記一方の建材に接続するための第1作業工程と、前記第1連結部材及び前記第2連結部材における他方の端部を前記他方の建材に接続するとともに、この接続を、前記間隔の方向に対する前記第1連結部材の傾き角度を前記間隔の方向に対する前記第2連結部材の傾き角度よりも大きくして行うための第2作業工程と、を含んでいることを特徴とするものである。 In the method of connecting building materials according to the present invention, two building materials arranged at intervals are arranged in a direction orthogonal to the direction of the distance and the thickness direction of one of the two building materials. In a method of connecting a building material by a plurality of connecting members that are provided and have different inclinations with respect to the direction of the spacing, the plurality of connecting members include a connecting portion connected to the one building material and the two building materials. The first connecting member having a large dimension between the connecting portion connected to the other building material, the connecting portion connected to the one building material, and the connecting portion connected to the other building material. There is a second connecting member having a smaller dimension between the first connecting member and the first working step for connecting one end of the first connecting member and the second connecting member to the one building material, and the above. The other end of the first connecting member and the second connecting member is connected to the other building material, and the connection is made such that the tilt angle of the first connecting member with respect to the direction of the spacing is the first with respect to the direction of the spacing. 2 It is characterized by including a second work step for performing the operation at a size larger than the inclination angle of the connecting member.

このため、本発明に係る建材の連結方法では、第1作業工程の後に実施される第2作業工程において、第1連結部材及び前記第2連結部材における他方の端部を前記他方の建材に接続する作業は、2つの建材の間隔の方向に対する第1連結部材の傾き角度を、2つの建材の間隔の方向に対する第2連結部材の傾き角度よりも大きくして行われるため、2つの建材を、これらの第1連結部材と第2連結部材により、2つの建材の間隔の方向と、2つの建材のうちの一方の建材の厚さ方向とに直交する方向に不動状態にして連結することができる。また、第1連結部材における前記一方の建材に接続された前記一方の端部と前記他方の建材に接続された前記他方の端部との間の寸法は大きくて、第2連結部材における前記一方の建材に接続された前記一方の端部と記他方の建材に接続された前記他方の端部との間の寸法は小さいため、第1連結部材の長さ寸法よりも第2連結部材の長さ寸法を短くすることができ、これにより、その分だけ材料の削減を達成して、2つの建材を連結できるようになる。 Therefore, in the method for connecting building materials according to the present invention, in the second work step carried out after the first work step, the other end portion of the first connecting member and the second connecting member is connected to the other building material. Since the work to be performed is performed by making the inclination angle of the first connecting member with respect to the direction of the distance between the two building materials larger than the inclination angle of the second connecting member with respect to the direction of the distance between the two building materials, the two building materials are used. With these first connecting members and the second connecting member, it is possible to immobilize and connect in a direction orthogonal to the direction of the distance between the two building materials and the thickness direction of one of the two building materials. .. Further, the dimension between the one end connected to the one building material in the first connecting member and the other end connected to the other building material is large, and the one in the second connecting member. Since the dimension between the one end connected to the building material and the other end connected to the other building material is small, the length of the second connecting member is longer than the length dimension of the first connecting member. The dimensions can be shortened, which enables the reduction of materials and the connection of two building materials.

図8には第1連結部材21が示され、図8(A)(B)(C)(D)は、この第1連結部材21の平面図、側面図、底面図、背面図である。金属板の打ち抜き及び折り曲げ品である第1連結部材21には、ドア枠2の厚さ方向となっている中心軸24の軸方向N1に離れている2個の連結部36が互いに対向して設けられ、これらの連結部36における中心軸24の軸方向N1と直交する側の第1連結部材21全体の厚さ方向の端部同士の間には、架け渡し部37が架け渡されている。このため、2個の連結部36は、中心軸24の軸方向N1を幅方向とする架け渡し部37により結合されており、それぞれの長さ方向の両端部がドア枠2と壁4側の補助部材8とに達するこれらの連結部36は、中心軸24の軸方向N1と第1連結部材21全体の厚さ方向とに直交する方向が長さ方向となったものになっている。 FIG. 8 shows the first connecting member 21, and FIGS. 8 (A), (B), (C), and (D) are a plan view, a side view, a bottom view, and a rear view of the first connecting member 21. On the first connecting member 21, which is a punched and bent product of a metal plate, two connecting portions 36 separated from each other in the axial direction N1 of the central shaft 24, which is the thickness direction of the door frame 2, face each other. A bridging portion 37 is provided between the end portions of the connecting portion 36 in the thickness direction of the entire first connecting member 21 on the side orthogonal to the axial direction N1 of the central axis 24. .. Therefore, the two connecting portions 36 are connected by a bridging portion 37 having the axial direction N1 of the central shaft 24 as the width direction, and both ends in the length direction of each are connected to the door frame 2 and the wall 4 side. These connecting portions 36 reaching the auxiliary member 8 have a length direction perpendicular to the axial direction N1 of the central axis 24 and the thickness direction of the entire first connecting member 21.

それぞれの連結部36の長さ方向の両端部36A,36Bのうち、補助部材8側の端部36Aには、図8(A)(C)に示されているように、中心軸24の軸方向N1に対して第1連結部材21の外側への傾斜角度となっているねじり角度θ1が設けられ、このねじり角度θ1は、2個の連結部36について互いに逆の向きのねじり角度となっており、また、ドア枠2側の端部36Bには、図8(A)(C)に示されているように、このようなねじり角度は設けられていない。そして、補助部材8側の端部36Aとドア枠2側の端部36Bとの間は、ねじり角度θ1を少しずつ消滅するための中間部36Cとなっている。ドア枠2側の端部36Bには、中心軸24を挿通させるための挿通部として大径の第1孔38が設けられているとともに、補助部材8側の端部36Aには、図4で示した結合具25を挿入するための小径の第2孔39が設けられている。 Of the both end portions 36A and 36B in the length direction of the respective connecting portions 36, the end portions 36A on the auxiliary member 8 side are the axes of the central shaft 24 as shown in FIGS. 8A and 8C. A twist angle θ1 that is an inclination angle toward the outside of the first connecting member 21 is provided with respect to the direction N1, and this twist angle θ1 is a twist angle that is opposite to each other with respect to the two connecting portions 36. Further, the end portion 36B on the door frame 2 side is not provided with such a twist angle as shown in FIGS. 8A and 8C. An intermediate portion 36C is provided between the end portion 36A on the auxiliary member 8 side and the end portion 36B on the door frame 2 side to gradually eliminate the twist angle θ1. The end 36B on the door frame 2 side is provided with a large-diameter first hole 38 as an insertion portion for inserting the central shaft 24, and the end 36A on the auxiliary member 8 side is shown in FIG. A second hole 39 having a small diameter for inserting the indicated coupling tool 25 is provided.

架け渡し部37には長孔40が設けられ、連結部36の長さ方向に長くなっているこの長孔40は、架け渡し部37の強度を低下させるためにこの架け渡し部37に形成された強度低下部となっている。 An elongated hole 40 is provided in the bridging portion 37, and the elongated hole 40 extending in the length direction of the connecting portion 36 is formed in the bridging portion 37 in order to reduce the strength of the bridging portion 37. It is a weakened part.

以上のように第1連結部材21は、2個の連結部36と、これらの連結部36に架け渡された架け渡し部37とにより形成された全体形状が略コの字状のものとなっているが、2個の連結部36におけるそれぞれの補助部材8側の端部36Aでの形状は、上述したねじり角度θ1のために、第1連結部材21の外側へ開いた、これを言い換えると、中心軸24の軸方向N1の外側へ開いたハの字状となっている。そして、大径の第1孔38が形成されている箇所が、図6及び図7で示した第1連結部材21におけるドア枠2の側枠部材2Aや上枠部材2Cとの接続部30になっているとともに、小径の第2孔39が形成されている箇所が、図6及び図7で示した第1連結部材21における壁4側の補助部材8との接続部31になっている。 As described above, the first connecting member 21 has a substantially U-shape as a whole formed by the two connecting portions 36 and the connecting portion 37 bridged to these connecting portions 36. However, the shape of each of the two connecting portions 36 at the end portion 36A on the side of the auxiliary member 8 is open to the outside of the first connecting member 21 due to the above-mentioned twist angle θ1, in other words. , It has a V shape that opens outward in the axial direction N1 of the central axis 24. The location where the large-diameter first hole 38 is formed is located at the connection portion 30 with the side frame member 2A and the upper frame member 2C of the door frame 2 in the first connecting member 21 shown in FIGS. 6 and 7. The portion where the second hole 39 having a small diameter is formed is the connection portion 31 with the auxiliary member 8 on the wall 4 side in the first connecting member 21 shown in FIGS. 6 and 7.

図9には、図4の結合具25により第1連結部材21における連結部36の補助部材8側の端部36Aを補助部材8に結合するために、それぞれの補助部材8側の端部36Aに、中心軸24の軸方向N1における互いに逆の向きの荷重W1を作用させたときを示している。このような荷重W1をそれぞれの補助部材8側の端部36Aに作用させると、これらの補助部材8側の端部36Aの図8で示したねじり角度θ1は減少又は消滅するとともに、架け渡し部37には、荷重W1の影響により、この架け渡し部37の厚さ方向(第1連結部材21全体の厚さ方向)のうち、第1連結部材21の外側へ突出する方向への湾曲等の変形が生じる。また、補助部材8側の端部36Aに中間部36Cを介して接続されているそれぞれのドア枠2側の端部36Bには、荷重W1の影響により、中心軸24の軸方向N1に対して第1連結部材21の内側への傾斜角度となったねじり角度θ2が生じ、このねじり角度θ2は、これらのドア枠2側の端部36Bについて、互いに逆の方向へのねじり角度となる。 In FIG. 9, in order to connect the end portion 36A on the auxiliary member 8 side of the connecting portion 36 of the first connecting member 21 to the auxiliary member 8 by the coupling tool 25 of FIG. 4, the end portion 36A on the auxiliary member 8 side is shown. Is shown when a load W1 in opposite directions to each other in the axial direction N1 of the central axis 24 is applied. When such a load W1 is applied to the end portion 36A on the side of each auxiliary member 8, the twist angle θ1 shown in FIG. 8 of the end portion 36A on the side of each auxiliary member 8 decreases or disappears, and the bridging portion Due to the influence of the load W1, the 37 is curved in the thickness direction of the bridging portion 37 (the thickness direction of the entire first connecting member 21) so as to project outward from the first connecting member 21. Deformation occurs. Further, the end 36B on the door frame 2 side connected to the end 36A on the auxiliary member 8 side via the intermediate portion 36C is affected by the load W1 with respect to the axial direction N1 of the central shaft 24. A twist angle θ2 that is an inward tilt angle of the first connecting member 21 is generated, and this twist angle θ2 is a twist angle in the opposite directions with respect to the end portions 36B on the door frame 2 side.

これにより、第1連結部材21の全体では、2個の連結部36におけるそれぞれのドア枠2側の端部36Bの形状が、ねじり角度θ2のために、第1連結部材21の内側へ閉じた逆ハの字状となる。 As a result, in the whole of the first connecting member 21, the shape of the end portion 36B on the door frame 2 side of each of the two connecting portions 36 is closed to the inside of the first connecting member 21 due to the twist angle θ2. It becomes an inverted C shape.

なお、架け渡し部37には、この架け渡し部37の強度を低下させるための強度低下部となっている長孔40が設けられているため、荷重W1により架け渡し部37は大きく上述したように湾曲等の変形を行いやすくなっており、このため、補助部材8側の端部36Aのねじり角度θ1の減少又は消滅と、ドア枠2側の端部36Bにおけるねじり角度θ2の発生も、一層確実に生ずるようになっている。 Since the bridging portion 37 is provided with a long hole 40 which is a strength reducing portion for reducing the strength of the bridging portion 37, the bridging portion 37 is largely as described above due to the load W1. Therefore, the twist angle θ1 of the end portion 36A on the auxiliary member 8 side is reduced or disappeared, and the twist angle θ2 is generated at the end portion 36B on the door frame 2 side. It is sure to occur.

図10には第2連結部材22が示され、図10(A)(B)(C)(D)は、この第2連結部材22の平面図、側面図、底面図、背面図である。第1連結部材21と同様に金属板の打ち抜き及び折り曲げ品となっている第2連結部材22は、第1連結部材21と比較して、第1連結部材21の前述した寸法L1が、第2連結部材22では前述した寸法L2となっている点だけが相違したものとなっている。したがって、第2連結部材22も、ドア枠2の厚さ方向となっている中心軸27の軸方向N2に離れている2個の連結部46が互いに対向して設けられたものになっているとともに、これらの連結部46における中心軸27の軸方向N2と直交する側の第2連結部材22全体の厚さ方向の端部同士の間に、架け渡し部47が架け渡されたものとなっている。このため、それぞれの長さ方向の両端部がドア枠2と壁4側の補助部材8とに達する2個の連結部46は、中心軸27の軸方向N2を幅方向とする架け渡し部47により結合されているとともに、それぞれの連結部46は、中心軸27の軸方向N2と第1連結部材21全体の厚さ方向とに直交する方向が長さ方向となったものになっている。 FIG. 10 shows the second connecting member 22, and FIGS. 10 (A), (B), (C), and (D) are a plan view, a side view, a bottom view, and a rear view of the second connecting member 22. The second connecting member 22, which is a punched and bent metal plate like the first connecting member 21, has the above-mentioned dimension L1 of the first connecting member 21 as compared with the first connecting member 21. The difference is that the connecting member 22 has the above-mentioned dimension L2. Therefore, the second connecting member 22 is also provided with two connecting portions 46 separated from each other in the axial direction N2 of the central axis 27, which is the thickness direction of the door frame 2. At the same time, the bridging portion 47 is bridged between the end portions in the thickness direction of the entire second connecting member 22 on the side orthogonal to the axial direction N2 of the central axis 27 in these connecting portions 46. ing. Therefore, the two connecting portions 46 having both ends in the length direction reaching the door frame 2 and the auxiliary member 8 on the wall 4 side are bridged portions 47 having the axial direction N2 of the central shaft 27 as the width direction. Each of the connecting portions 46 is connected in the length direction in a direction orthogonal to the axial direction N2 of the central axis 27 and the thickness direction of the entire first connecting member 21.

また、それぞれの連結部46の長さ方向の両端部46A,46Bのうち、補助部材8側の端部46Aには、図10(A)(C)に示されているように、中心軸27の軸方向N2に対して第2連結部材22の外側への傾斜角度となっているねじり角度θ3が設けられ、このねじり角度θ3は、2個の連結部46について互いに逆の向きのねじり角度となっており、また、ドア枠2側の端部46Bには、図10(A)(C)に示されているように、このようなねじり角度は設けられていない。そして、補助部材8側の端部46Aとドア枠2側の端部46Bとの間は、ねじり角度θ3を少しずつ消滅するための中間部46Cとなっており、ドア枠2側の端部46Bには、中心軸27を挿通させるための挿通部として大径の第1孔48が設けられ、補助部材8側の端部46Aには、図5で示した結合具28を挿入するための小径の第2孔49が設けられている。さらに、架け渡し部47には長孔50が設けられ、連結部46の長さ方向に長くなっているこの長孔50は、第1連結部材21の長孔40と同様に、架け渡し部47の強度を低下させるためにこの架け渡し部47に形成された強度低下部となっている。 Further, of the both end portions 46A and 46B in the length direction of the respective connecting portions 46, the end portions 46A on the auxiliary member 8 side have a central shaft 27 as shown in FIGS. 10A and 10C. A twist angle θ3 which is an inclination angle to the outside of the second connecting member 22 is provided with respect to the axial direction N2 of the above, and this twist angle θ3 is a twist angle in opposite directions with respect to the two connecting portions 46. Further, the end portion 46B on the door frame 2 side is not provided with such a twist angle as shown in FIGS. 10A and 10C. An intermediate portion 46C for gradually eliminating the twist angle θ3 is formed between the end portion 46A on the auxiliary member 8 side and the end portion 46B on the door frame 2 side, and the end portion 46B on the door frame 2 side. Is provided with a large-diameter first hole 48 as an insertion portion for inserting the central shaft 27, and the end portion 46A on the auxiliary member 8 side has a small diameter for inserting the coupling tool 28 shown in FIG. The second hole 49 is provided. Further, the connecting portion 47 is provided with a long hole 50, and the long hole 50, which is elongated in the length direction of the connecting portion 46, is the same as the long hole 40 of the first connecting member 21, and the connecting portion 47 is provided. It is a strength reducing portion formed in the bridging portion 47 in order to reduce the strength of the above.

以上の説明から分かるように、第2連結部材22も、第1連結部材21と同様に、2個の連結部46と、これらの連結部46に架け渡された架け渡し部47とにより形成された全体形状が略コの字状のものとなっているとともに、2個の連結部46におけるそれぞれの補助部材8側の端部46Aでの形状は、上述したねじり角度θ3のために、第2連結部材22の外側へ開いた、すなわち、中心軸27の軸方向N2の外側へ開いたハの字状となっている。そして、大径の第1孔48が形成されている箇所が、図6及び図7で示した第2連結部材22におけるドア枠2の側枠部材2Aや上枠部材2Cとの接続部32になっているとともに、小径の第2孔49が形成されている箇所が、図6及び図7で示した第2連結部材22における壁4側の補助部材8との接続部33になっている。 As can be seen from the above description, the second connecting member 22 is also formed by the two connecting portions 46 and the connecting portion 47 bridged to these connecting portions 46, similarly to the first connecting member 21. The overall shape is substantially U-shaped, and the shape at the end 46A on the side of each auxiliary member 8 in the two connecting portions 46 is the second due to the above-mentioned twist angle θ3. It has a V shape that opens to the outside of the connecting member 22, that is, opens to the outside of the central axis 27 in the axial direction N2. The location where the first hole 48 having a large diameter is formed is located at the connection portion 32 with the side frame member 2A and the upper frame member 2C of the door frame 2 in the second connecting member 22 shown in FIGS. 6 and 7. The portion where the second hole 49 having a small diameter is formed is the connection portion 33 with the auxiliary member 8 on the wall 4 side in the second connecting member 22 shown in FIGS. 6 and 7.

図11には、図5の結合具28により第2連結部材22における連結部46の補助部材8側の端部46Aを補助部材8に結合するために、それぞれの補助部材8側の端部46Aに、中心軸27の軸方向N2における互いに逆の向きの荷重W2を作用させたときを示している。このような荷重W2をそれぞれの補助部材8側の端部46Aに作用させると、これらの補助部材8側の端部46Aの図10で示したねじり角度θ3は減少又は消滅するとともに、架け渡し部47には、荷重W2の影響により、この架け渡し部47の厚さ方向となっている第2連結部材22全体の厚さ方向のうち、第2連結部材22の外側へ突出する方向への湾曲等の変形が生じる。また、補助部材8側の端部46Aに中間部46Cを介して接続されているそれぞれのドア枠2側の端部46Bには、荷重W2の影響により、中心軸27の軸方向N2に対して第2連結部材22の内側への傾斜角度となったねじり角度θ4が生じ、このねじり角度θ4は、これらのドア枠2側の端部46Bについて、互いに逆の方向へのねじり角度となる。 In FIG. 11, in order to connect the end portion 46A on the auxiliary member 8 side of the connecting portion 46 of the second connecting member 22 to the auxiliary member 8 by the coupling tool 28 of FIG. 5, the end portion 46A on the auxiliary member 8 side is shown. Is shown when a load W2 in opposite directions to each other in the axial direction N2 of the central axis 27 is applied. When such a load W2 is applied to the end portion 46A on the side of each auxiliary member 8, the twist angle θ3 shown in FIG. 10 of the end portion 46A on the side of each auxiliary member 8 decreases or disappears, and the bridging portion Due to the influence of the load W2, the 47 is curved in the direction of protruding outward from the second connecting member 22 in the thickness direction of the entire second connecting member 22 which is the thickness direction of the bridging portion 47. Etc. occur. Further, the end portion 46B on the door frame 2 side connected to the end portion 46A on the auxiliary member 8 side via the intermediate portion 46C is affected by the load W2 with respect to the axial direction N2 of the central shaft 27. A twist angle θ4 that is an inward tilt angle of the second connecting member 22 is generated, and this twist angle θ4 is a twist angle in the opposite directions with respect to the end portions 46B on the door frame 2 side.

これにより、第1連結部材21と同様に、第2連結部材22の全体では、2個の連結部46におけるそれぞれのドア枠2側の端部46Bの形状が、ねじり角度θ4のために、第2連結部材22の内側へ閉じた逆ハの字状となる。 As a result, as in the case of the first connecting member 21, in the whole of the second connecting member 22, the shape of the end portion 46B on the door frame 2 side of each of the two connecting portions 46 is changed due to the twist angle θ4. 2 It becomes an inverted C shape closed inside the connecting member 22.

なお、第2連結部材22の架け渡し部47にも、この架け渡し部47の強度を低下させるための強度低下部となっている長孔50が設けられているため、荷重W2により架け渡し部47は大きく湾曲等の変形を行いやすくなっており、したがって、補助部材8側の端部46Aのねじり角度θ3の減少又は消滅と、ドア枠2側の端部46Bにおけるねじり角度θ2の発生も、一層確実に生ずる。 Since the connecting portion 47 of the second connecting member 22 is also provided with a long hole 50 which is a strength reducing portion for reducing the strength of the connecting portion 47, the connecting portion is provided with a load W2. 47 is greatly deformed such as curved, and therefore, the twist angle θ3 of the end portion 46A on the auxiliary member 8 side is reduced or disappeared, and the twist angle θ2 is generated at the end portion 46B on the door frame 2 side. It happens more reliably.

以上説明した第1及び第2連結具20A,20Bは、ドア枠2と同様に、工場で製造される。すなわち、第1連結具20Aについては、第1連結部材21の2個の連結部36に形成された大径の第1孔38に中心軸24に挿通するとともに、この中心軸24を、図4に示されているように、軸受け部材23の2個の延出部23Bに形成された孔に挿通し、中心軸24の両端部に軸受け部材23からの抜け止め部24Aを設ける加工を行うことにより、第1連結具20Aが工場で製造される。また、第2連結具20Bについても、第2連結部材22の2個の連結部46に形成された大径の第1孔48に中心軸27に挿通するとともに、この中心軸27を、図5に示されているように、軸受け部材26の2個の延出部26Bに形成された孔に挿通し、中心軸27の両端部に軸受け部材26からの抜け止め部27Aを設ける加工を行うことにより、第2連結具20Bが工場で製造される。 The first and second couplers 20A and 20B described above are manufactured at the factory in the same manner as the door frame 2. That is, for the first connecting tool 20A, the central shaft 24 is inserted into the large-diameter first hole 38 formed in the two connecting portions 36 of the first connecting member 21, and the central shaft 24 is shown in FIG. As shown in the above, the bearing member 23 is inserted into the holes formed in the two extension portions 23B, and the retaining portions 24A from the bearing member 23 are provided at both ends of the central shaft 24. The first connector 20A is manufactured at the factory. Further, also for the second connecting tool 20B, the central shaft 27 is inserted into the large-diameter first hole 48 formed in the two connecting portions 46 of the second connecting member 22, and the central shaft 27 is shown in FIG. As shown in the above, the bearing member 26 is inserted into the holes formed in the two extension portions 26B, and the central shaft 27 is provided with the retaining portions 27A from the bearing member 26 at both ends. The second connector 20B is manufactured at the factory.

そして、これらの第1及び第2連結具20A,20Bは、工場において、図4及び図5に示されているように、それぞれの軸受け部材23,26におけるドア枠2の厚さ方向両側の端部部分23A,26Aを、ドア枠2の左右の側枠部材2A,2B、上枠部材2Cに溶接等で結合することにより、ドア枠2のそれぞれに箇所に取り付けられる。 Then, these first and second connectors 20A and 20B are the ends on both sides in the thickness direction of the door frame 2 in the bearing members 23 and 26, respectively, as shown in FIGS. 4 and 5 in the factory. By connecting the portions 23A and 26A to the left and right side frame members 2A and 2B of the door frame 2 and the upper frame member 2C by welding or the like, they are attached to the respective parts of the door frame 2.

なお、このときの第1及び第2連結具20A,20Bにおける第1及び第2連結部材21,22の回動中心軸となっているそれぞれの中心軸24,27は、これらの中心軸24,27の軸方向N1,N2がドア枠2の厚さ方向となり、このようにそれぞれの中心軸24,27は、互いに平行又は略平行となってドア枠2の左右の側枠部材2A,2B、上枠部材2Cに配置される。 At this time, the central axes 24 and 27, which are the rotation central axes of the first and second connecting members 21 and 22 in the first and second connecting tools 20A and 20B, are the central axes 24, respectively. The axial directions N1 and N2 of 27 are in the thickness direction of the door frame 2, and thus the central axes 24 and 27 are parallel or substantially parallel to each other, and the left and right side frame members 2A and 2B of the door frame 2 are It is arranged on the upper frame member 2C.

また、上述したように第1及び第2連結部材21,22に設けられた大径の第1孔38,48に中心軸24,27を挿通させる作業や、その他の作業を行い、これにより、第1及び第2連結具20A,20Bを、工場において、ドア枠2のそれぞれに箇所に取り付ける作業を実施することにより、第1及び第2連結部材21,22におけるドア枠2側の端部をこのドア枠2に接続するための作業が、工場で実施されたことになる。 Further, as described above, the work of inserting the central shafts 24 and 27 into the large-diameter first holes 38 and 48 provided in the first and second connecting members 21 and 22 and other work are performed, whereby the work is performed. By carrying out the work of attaching the first and second connecting tools 20A and 20B to the respective parts of the door frame 2 in the factory, the end portions of the first and second connecting members 21 and 22 on the door frame 2 side can be attached. The work for connecting to the door frame 2 has been carried out at the factory.

After being attached, the door frame 2 is carried to the hinged door device installation site where the hinged door device shown in FIG. 1 is installed, and inside the opening 4A formed in the above-mentioned wall 4 at this installation site, the first door frame 2 is installed. The work of inserting and arranging the door frame 2 provided with the first and the second connecting tools 20A and 20B is performed.

By abutting the connecting portions 23C and 26C, the work of receiving the first and second connecting members 21 and 22 by the bearing members 23 and 26 is performed.

これにより、ドア枠2に取り付けられている第1及び第2連結具20A,20Bにおける第1及び第2連結部材21,22は、ドア枠2側へ折り畳まれた状態となってドア枠2の内部空間に全体又は略全体が収納された状態になるため、これらの第1及び第2連結部材21,22は、ドア枠2側へ傾いた姿勢となる。このため、このように第1及び第2連結部材21,22をドア枠2側へ傾いた姿勢とさせることにより、図3で示されているドア枠2の左側の側枠部材2Aと、この側枠部材2Aと左右方向に対向して、壁4の芯部材5Aに補強部材7により取り付けられた補助部材8との間隔(図6の寸法L3で示されている間隔)や、ドア枠2の右側の側枠部材2Bと、この側枠部材2Bと左右方向に対向して、壁4の芯部材5Bに補強部材7により取り付けられた補助部材8との間隔、さらには、ドア枠2の上枠部材2Cと、この上枠部材2Cと上下方向に対向して、壁4の芯部材5Cに補強部材7により取り付けられた補助部材8との間隔(図7の寸法L4で示されている間隔)が、小さくなっていても、第1及び第2連結具20A,20Bを備えているドア枠2を、壁4に形成されている開口部4Aの内側に挿入配置するための作業を、第1及び第2連結部材21,22に影響されることなく、容易に実施することができる。 As a result, the first and second connecting members 21 and 22 in the first and second connecting tools 20A and 20B attached to the door frame 2 are in a state of being folded toward the door frame 2 side, and the door frame 2 is in a state of being folded. Since the whole or substantially the whole is housed in the internal space, these first and second connecting members 21 and 22 are in an inclined posture toward the door frame 2. Therefore, by tilting the first and second connecting members 21 and 22 toward the door frame 2 in this way, the left side frame member 2A of the door frame 2 shown in FIG. 3 and the side frame member 2A thereof. The distance between the side frame member 2A and the auxiliary member 8 attached to the core member 5A of the wall 4 by the reinforcing member 7 (the distance shown by the dimension L3 in FIG. 6) facing the side frame member 2A in the left-right direction, and the door frame 2 The distance between the side frame member 2B on the right side of the wall 4 and the auxiliary member 8 attached to the core member 5B of the wall 4 by the reinforcing member 7 so as to face the side frame member 2B in the left-right direction, and further, the door frame 2 The distance between the upper frame member 2C and the auxiliary member 8 attached to the core member 5C of the wall 4 by the reinforcing member 7 so as to face the upper frame member 2C in the vertical direction (shown by the dimension L4 in FIG. 7). Even if the interval) is small, the work for inserting and arranging the door frame 2 provided with the first and second connecting tools 20A and 20B inside the opening 4A formed in the wall 4 is performed. It can be easily carried out without being affected by the first and second connecting members 21 and 22.

なお、壁4の補強部材7に補助部材8を取り付ける作業は、以上のようにして第1及び第2連結具20A,20Bが取り付けられたドア枠2を壁4の開口部4Aの内側に挿入配置する作業を行う直前において行ってもよく、あるいは、この作業を、第1及び第2連結具20A,20Bが取り付けられたドア枠2が開き戸装置設置現場に運ばれる以前において行ってもよい。 In the work of attaching the auxiliary member 8 to the reinforcing member 7 of the wall 4, the door frame 2 to which the first and second connecting tools 20A and 20B are attached is inserted inside the opening 4A of the wall 4 as described above. It may be performed immediately before the arranging work is performed, or this work may be performed before the door frame 2 to which the first and second connecting tools 20A and 20B are attached is carried to the hinged door device installation site.

第1及び第2連結具20A,20Bが取り付けられたドア枠2を壁4の開口部4Aの内側に挿入配置した後に、作業者は、例えば、これらの第1及び第2連結具20A,20Bにおける第1及び第2連結部材21,22に形成されている小径の第2孔39,49に先端を挿入したドライバ等の工具により、第1及び第2連結部材21,22を中心軸24,27を中心に壁4の補助部材8側に回動させる作業を行い、この回動作業を、図6及び図7に示されているように、第1及び第2連結部材21,22のそれぞれの連結部36,47の先端面が壁4側の補強部材7に当接するまで行い、これにより、図14及び図15に示されているように、これらの第1及び第2連結部材21,22におけるそれぞれ2個の連結部36,46の補助部材8側の端部36A同士の間及び端部46A同士の間に、壁4側の補助部材8を挿入する。 After inserting and arranging the door frame 2 to which the first and second connectors 20A and 20B are attached inside the opening 4A of the wall 4, the operator can use, for example, these first and second connectors 20A and 20B. With a tool such as a screwdriver whose tip is inserted into the small-diameter second holes 39, 49 formed in the first and second connecting members 21 and 22 in The work of rotating the wall 4 toward the auxiliary member 8 around the 27 is performed, and this rotation work is performed by the first and second connecting members 21 and 22, respectively, as shown in FIGS. 6 and 7. Until the tip surface of the connecting portions 36, 47 abuts on the reinforcing member 7 on the wall 4 side, thereby, as shown in FIGS. 14 and 15, these first and second connecting members 21, The auxiliary member 8 on the wall 4 side is inserted between the end portions 36A on the auxiliary member 8 side of the two connecting portions 36 and 46, respectively, and between the end portions 46A.

なお、第1及び第2連結部材21,22に設ける架け渡し部37,47についての連結部36,46の長さ方向の長さ寸法を大きくすることにより、第1及び第2連結部材21,22を中心軸24,27を中心に壁4の補助部材8側に回動させる作業を、架け渡し部37,47の先端部が壁4側の補助部材8に当接するまで行うようにしてもよい。 The first and second connecting members 21, Even if the work of rotating 22 around the central shafts 24 and 27 toward the auxiliary member 8 of the wall 4 is performed until the tips of the bridging portions 37 and 47 come into contact with the auxiliary member 8 on the wall 4 side. good.

以上の作業を行ったときには、図14及び図15に示されているように、第1及び第2連結部材21,22における中心軸24,27の軸方向の両側部分と、中心軸24,27を支持している軸受け部材23,26の前述したそれぞれ2個の延出部23B,26Bとの間には、中心軸24,27の軸方向のすき間が設けられているため、ドア枠2は、これらのすき間分だけ中心軸24,27の軸方向に移動可能となっている。このため、作業者は、ドア枠2を、第1及び第2連結部材21,22に対し中心軸24,27に案内させてドア枠2の厚さ方向に移動させることにより、このドア枠2を、壁4側の建材となっている補助部材8に対してドア枠2の厚さ方向の所定の位置に配置する作業を行うことができる。 When the above work is performed, as shown in FIGS. 14 and 15, both side portions of the central shafts 24 and 27 in the first and second connecting members 21 and 22 in the axial direction and the central shafts 24 and 27 are performed. The door frame 2 is provided with a gap in the axial direction of the central shafts 24 and 27 between the two extension portions 23B and 26B of the bearing members 23 and 26 supporting the above-mentioned bearing members 23 and 26, respectively. , It is possible to move in the axial direction of the central axes 24 and 27 by the amount of these gaps. Therefore, the operator guides the door frame 2 to the central shafts 24 and 27 with respect to the first and second connecting members 21 and 22, and moves the door frame 2 in the thickness direction of the door frame 2. Can be arranged at a predetermined position in the thickness direction of the door frame 2 with respect to the auxiliary member 8 which is a building material on the wall 4 side.

なお、このようにドア枠2を、第1及び第2連結部材21,22に対し中心軸24,27に案内させてドア枠2の厚さ方向に移動させることにより、これを言い換えると、第1及び第2連結部材21,22を、ドア枠2に対し中心軸24,27に案内させてドア枠2の厚さ方向に移動させることにより、ドア枠2を、壁4側の建材となっている補助部材8に対してドア枠2の厚さ方向の所定の位置に配置するための作業は、ドア枠2を壁4の開口部4Aの内側に挿入配置する以前や、第1及び第2連結部材21,22を中心軸24,27を中心に壁4の補助部材8側に回動させる作業を行う直前等に実施してもよい。 In this way, the door frame 2 is guided to the central shafts 24 and 27 with respect to the first and second connecting members 21 and 22 and moved in the thickness direction of the door frame 2, in other words, the first. By guiding the 1st and 2nd connecting members 21 and 22 to the central shafts 24 and 27 with respect to the door frame 2 and moving them in the thickness direction of the door frame 2, the door frame 2 becomes a building material on the wall 4 side. The work for arranging the door frame 2 at a predetermined position in the thickness direction with respect to the auxiliary member 8 is performed before the door frame 2 is inserted and arranged inside the opening 4A of the wall 4, and the first and first steps are performed. 2 The connecting members 21 and 22 may be carried out immediately before the work of rotating the connecting members 21 and 22 toward the auxiliary member 8 side of the wall 4 around the central shafts 24 and 27.

また、本実施形態によると、前述したように、第1及び第2連結部材21,22におけるそれぞれ2個の連結部36,46の補助部材8側の端部36A同士の間及び端部46A同士の間に、補助部材8を挿入する作業を行う際に、この補助部材8が、補助部材8の長さ方向に正確に直線状となっておらず、補助部材8の長さ方向と直交する補助部材8の幅方向(ドア枠2の厚さ方向)に多少変形していても、この変形を、第1及び第2連結部材21,22を中心軸24の軸方向に移動させることによって吸収しながら、上述の補助部材8の挿入作業を実施することができる。 Further, according to the present embodiment, as described above, between the end portions 36A of the two connecting portions 36, 46 on the auxiliary member 8 side of the first and second connecting members 21 and 22, and between the end portions 46A, respectively. When the work of inserting the auxiliary member 8 is performed, the auxiliary member 8 is not exactly linear in the length direction of the auxiliary member 8 and is orthogonal to the length direction of the auxiliary member 8. Even if the auxiliary member 8 is slightly deformed in the width direction (thickness direction of the door frame 2), this deformation is absorbed by moving the first and second connecting members 21 and 22 in the axial direction of the central shaft 24. While doing so, the above-mentioned auxiliary member 8 can be inserted.

そして、この後に作業者は、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aを、図4、図6及び図7で示されている結合具25と、図5〜図7で示されている結合具28とを、それぞれの連結部36,46に設けられた第2孔39、49に挿入して補助部材8にねじ込むことにより、図4〜図7に示されているように補助部材8に結合する作業を行う。 Then, after this, the operator views the ends 36A, 46A on the auxiliary member 8 side of the two connecting portions 36, 46 of the first and second connecting members 21 and 22, respectively, in FIGS. 4, 6 and 7. The coupling tool 25 shown and the coupling tool 28 shown in FIGS. 5 to 7 are inserted into the second holes 39 and 49 provided in the respective connecting portions 36 and 46 into the auxiliary member 8. By screwing in, the work of connecting to the auxiliary member 8 is performed as shown in FIGS. 4 to 7.

これにより、第1及び第2連結部材21,22における壁4側の端部が壁4側の補強部材7に補助部材8を介して結合具25,28により接続される作業が実施されたことになる。 As a result, the work of connecting the ends of the first and second connecting members 21 and 22 on the wall 4 side to the reinforcing member 7 on the wall 4 side by the couplers 25 and 28 via the auxiliary member 8 was carried out. become.

なお、結合具25,28はドリルねじであるため、結合具25,28による第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aを補助部材8に結合する作業は、結合具25,28が補助部材8にねじ切り孔加工を行うことにより実施される。このため、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aに第2孔39,49を設けず、結合具25,28により、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aを補助部材8に結合するための作業を、ねじ切り孔加工結合具となっている結合具25,28により、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aと、補助部材8との両方にねじ切り孔加工を行うことにより実施してもよい。 Since the couplers 25 and 28 are drill screws, the end portions 36A on the auxiliary member 8 side of the two connecting portions 36 and 46 of the first and second connecting members 21 and 22 by the couplers 25 and 28, respectively. The work of connecting the 46A to the auxiliary member 8 is carried out by the fittings 25 and 28 making a thread drilling hole in the auxiliary member 8. Therefore, the second holes 39 and 49 are not provided in the ends 36A and 46A on the auxiliary member 8 side of the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively, and the couplers 25 and 28 are not provided. The work for connecting the end portions 36A, 46A on the auxiliary member 8 side of the two connecting portions 36, 46 of the first and second connecting members 21 and 22, respectively, to the auxiliary member 8 is performed by the thread cutting hole processing coupling tool. Both the end portions 36A and 46A on the auxiliary member 8 side and the auxiliary member 8 in the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively, by the coupling tools 25 and 28. It may be carried out by drilling a threaded hole.

なお、このようにして結合具25,28により、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aを補助部材8に結合するための作業は、前述したように、第1及び第2連結部材21,22を中心軸24,27を中心に壁4の補助部材8側に回動させるとともに、この回動作業を、第1及び第2連結部材21,22のそれぞれの連結部36,47の先端面が壁4側の補強部材7に当接するまで行った後に実施するため、この回動作業を、作業者は前述した工具等により容易に実施することができる。 In this way, the connecting tools 25 and 28 connect the ends 36A and 46A on the auxiliary member 8 side of the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively, to the auxiliary member 8. As described above, the first and second connecting members 21 and 22 are rotated around the central shafts 24 and 27 toward the auxiliary member 8 of the wall 4, and this rotation work is performed. Since the operation is performed after the tip surfaces of the connecting portions 36 and 47 of the first and second connecting members 21 and 22 come into contact with the reinforcing member 7 on the wall 4 side, the operator has described this rotation work. It can be easily carried out with a tool or the like.

また、結合具25,28が、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aと、補助部材8とのうち、少なくとも補助部材8をねじ切り孔加工するものとなっていても、上述の工具により、第1及び第2連結部材21,22のそれぞれの連結部36,47の先端面を壁4側の補強部材7に当接させておくことにより、このねじ切り孔加工を、第1及び第2連結部材21,22が中心軸24,27を中心に揺動等の微動することを防止して容易に実施することができる。 Further, the couplers 25 and 28 are at least among the ends 36A and 46A on the auxiliary member 8 side and the auxiliary member 8 in the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively. Even if the auxiliary member 8 is to be threaded, the tip surfaces of the connecting portions 36 and 47 of the first and second connecting members 21 and 22, respectively, can be used as the reinforcing member 7 on the wall 4 side by the above-mentioned tool. By keeping them in contact with each other, it is possible to easily perform this thread cutting hole processing by preventing the first and second connecting members 21 and 22 from making slight movements such as swinging around the central shafts 24 and 27. can.

結合具25,28による上述した結合作業を行うと、ドア枠2と、このドア枠2の左右の側枠部材2A,2Bと左右方向に対向している壁4側の補強部材7とは、側枠部材2A,2Bに取り付けられている第1及び第2連結具20A,20Bにおける第1及び第2連結部材21,22により、補助部材8を介して連結されることになる。そして、この連結作業は、第1連結部材21については、図6に示されているように、ドア枠2の側枠部材2Aと補助部材8との間隔の方向に対して傾き角度がα1となって行われ、また、第2連結部材22については、図6に示されているように、上記間隔の方向に対して傾き角度がα2となって行われ、このため、第1及び第2連結部材21,22についての上記間隔の方向に対して傾きが異なっているため、ドア枠2の左右の側枠部材2A,2Bは、補助部材8に対して上下方向に不動状態となって連結されていることになる。 When the above-mentioned joining work is performed by the fittings 25 and 28, the door frame 2 and the reinforcing member 7 on the wall 4 side facing the left and right side frame members 2A and 2B of the door frame 2 in the left-right direction are separated from each other. The first and second connecting members 21 and 22 in the first and second connecting tools 20A and 20B attached to the side frame members 2A and 2B are connected via the auxiliary member 8. Then, in this connecting operation, as shown in FIG. 6, the inclination angle of the first connecting member 21 is α1 with respect to the direction of the distance between the side frame member 2A of the door frame 2 and the auxiliary member 8. As shown in FIG. 6, the second connecting member 22 is tilted at an inclination angle of α2 with respect to the direction of the interval, and therefore, the first and second connecting members 22 are performed. Since the inclinations of the connecting members 21 and 22 are different with respect to the direction of the above interval, the left and right side frame members 2A and 2B of the door frame 2 are connected to the auxiliary member 8 in a vertically immovable state. It will be done.

なお、ドア枠2の側枠部材2A,2Bに取り付けられている第1連結部材21と第2連結部材22についての傾き角度α1,α2は、図6で示されているドア枠2と補助部材8との間の左右方向の間隔L3の大きさに応じたものとなる。このため、結合具25,28によって第1及び第2連結部材21,22を補助部材8に結合する以前において、図3に示されているように、ドア枠2を、このドア枠2の左右両側に2個配置されている壁4側の補助部材8に対して左右方向の適正の位置に配置した後に、結合具25,28によって第1及び第2連結部材21,22を補助部材8に結合することにより、ドア枠2の配置位置を、それぞれの補助部材8に対して適正の位置とすることができる。 The inclination angles α1 and α2 for the first connecting member 21 and the second connecting member 22 attached to the side frame members 2A and 2B of the door frame 2 are the door frame 2 and the auxiliary member shown in FIG. It depends on the size of the distance L3 in the left-right direction between 8 and 8. Therefore, before connecting the first and second connecting members 21 and 22 to the auxiliary member 8 by the couplers 25 and 28, as shown in FIG. 3, the door frame 2 is attached to the left and right sides of the door frame 2. After arranging two auxiliary members 8 on the wall 4 side on both sides at appropriate positions in the left-right direction, the first and second connecting members 21 and 22 are attached to the auxiliary members 8 by the couplers 25 and 28. By combining, the arrangement position of the door frame 2 can be set to an appropriate position with respect to each auxiliary member 8.

このため、ドア枠2の左右の側枠部材2A,2Bのうち、左側の側枠部材2Aと、この側枠部材2Aと左右方向に対向している補助部材8との間の間隔の大きさと、右側の側枠部材2Bと、この側枠部材2Bと左右方向に対向している補助部材8との間の間隔の大きさとが異なっている場合には、左側の側枠部材2Aに取り付けられている第1及び第2連結部材21,22についての傾き角度の大きさと、右側の側枠部材2Bに取り付けられている第1及び第2連結部材21,22についての傾き角度の大きさは、異なることになる。 Therefore, among the left and right side frame members 2A and 2B of the door frame 2, the size of the distance between the left side frame member 2A and the auxiliary member 8 facing the side frame member 2A in the left-right direction is large. If the size of the distance between the right side frame member 2B and the side frame member 2B facing the auxiliary member 8 in the left-right direction is different, the side frame member 2A is attached to the left side frame member 2A. The magnitude of the tilt angle of the first and second connecting members 21 and 22 and the magnitude of the tilt angle of the first and second connecting members 21 and 22 attached to the right side frame member 2B are as follows. It will be different.

そして、上述したようにドア枠2の側枠部材2A,2Bに取り付けられている第1連結部材21と第2連結部材22についての傾き角度α1,α2が、ドア枠2と補助部材8との間の左右方向の間隔L3の大きさに応じたものになっても、結合具25,28は、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aと、補助部材8とのうち、少なくとも補助部材8をねじ切り孔加工するものとなっているため、結合具25,28により、第1及び第2連結部材21,22を補助部材8に結合することができる。 Then, as described above, the inclination angles α1 and α2 for the first connecting member 21 and the second connecting member 22 attached to the side frame members 2A and 2B of the door frame 2 are the door frame 2 and the auxiliary member 8. Even if the distance between them in the left-right direction depends on the size of L3, the couplers 25 and 28 still have the auxiliary members 8 in the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively. Of the side ends 36A and 46A and the auxiliary member 8, at least the auxiliary member 8 is threaded, so that the first and second connecting members 21 and 22 are connected by the binders 25 and 28. It can be coupled to the auxiliary member 8.

以上の説明は、ドア枠2の左右の側枠部材2A,2Bに取り付けられた第1及び第2連結具20A,20Bにおける第1及び第2連結部材21,22により、ドア枠2の左右の側枠部材2A,2Bと、これらの側枠部材2A,2Bと左右方向に対向している壁4側の補助部材8とを連結するための作業についてであったが、ドア枠2の上枠部材2Cに取り付けられた第1及び第2連結具20A,20Bにおける第1及び第2連結部材21,22を、結合具25,28により、上枠枠部材2Cと上下方向に対向している壁4側の補助部材8に連結した場合には、第1連結部材21については、図7に示されているように、ドア枠2の上枠部材2Cと補助部材8との間隔の方向に対する傾き角度がα3となり、また、第2連結部材22については、上記間隔の方向に対して傾き角度がα4となるため、第1及び第2連結部材21,22についての上記間隔の方向に対して傾きが異なっていることにより、ドア枠2の上枠部材2Cは、補助部材8に対して左右方向に不動状態となって連結されることになる。 The above description is given by the first and second connecting members 21 and 22 in the first and second connecting members 20A and 20B attached to the left and right side frame members 2A and 2B of the door frame 2 to the left and right of the door frame 2. The work for connecting the side frame members 2A and 2B and the auxiliary members 8 on the wall 4 side facing the side frame members 2A and 2B in the left-right direction was the work for connecting the upper frame of the door frame 2. A wall in which the first and second connecting members 21 and 22 in the first and second connecting members 20A and 20B attached to the member 2C are vertically opposed to the upper frame frame member 2C by the connecting members 25 and 28. When connected to the auxiliary member 8 on the 4th side, the first connecting member 21 is tilted with respect to the direction of the distance between the upper frame member 2C of the door frame 2 and the auxiliary member 8 as shown in FIG. Since the angle is α3 and the tilt angle of the second connecting member 22 is α4 with respect to the direction of the spacing, the second connecting member 22 is tilted with respect to the direction of the spacing of the first and second connecting members 21 and 22. However, the upper frame member 2C of the door frame 2 is connected to the auxiliary member 8 in an immovable state in the left-right direction.

なお、これらの第1及び第2連結部材21,22についての傾き角度α3,α4は、図7で示されているドア枠2の上枠部材2Cと補助部材8との間の上下方向の間隔L4の大きさに応じたものとなる。このため、結合具25,28によって第1及び第2連結部材21,22を補助部材8に結合する以前において、ドア枠2を、このドア枠2の上側に配置されている壁4側の補助部材8に対して上下方向の適正の位置に配置した後に、結合具25,28によって第1及び第2連結部材21,22を補助部材8に結合することにより、ドア枠2の配置位置を、壁4の前述した開口部4A内における適正の上下方向の位置とすることができ、また、ドア枠2を、補助部材8に対して左右方向に不動状態にすることができる。 The inclination angles α3 and α4 for the first and second connecting members 21 and 22 are the vertical distances between the upper frame member 2C of the door frame 2 and the auxiliary member 8 shown in FIG. It depends on the size of L4. Therefore, before the first and second connecting members 21 and 22 are connected to the auxiliary member 8 by the couplers 25 and 28, the door frame 2 is attached to the auxiliary on the wall 4 side arranged above the door frame 2. After arranging the door frame 2 at an appropriate position in the vertical direction with respect to the member 8, the first and second connecting members 21 and 22 are connected to the auxiliary member 8 by the coupling tools 25 and 28, so that the arrangement position of the door frame 2 is set. It can be positioned in the above-mentioned opening 4A of the wall 4 in the proper vertical direction, and the door frame 2 can be immovable in the left-right direction with respect to the auxiliary member 8.

また、第1及び第2連結部材21,22についての傾き角度α3,α4が、ドア枠2の上枠部材2Cと補助部材8との間の上下方向の間隔L4の大きさに応じたものとなっても、結合具25,28は、前述したようにねじ切り孔加工結合具であるため、第1及び第2連結部材21,22のそれぞれ2個の連結部36,46における補助部材8側の端部36A,46Aと、補助部材8とのうち、少なくとも補助部材8をねじ切り孔加工することにより、これらの結合具25,28により、第1及び第2連結部材21,22を補助部材8に結合することができる。 Further, the inclination angles α3 and α4 for the first and second connecting members 21 and 22 correspond to the size of the vertical distance L4 between the upper frame member 2C and the auxiliary member 8 of the door frame 2. Even so, since the coupling tools 25 and 28 are threaded hole processing coupling tools as described above, they are on the auxiliary member 8 side of the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively. Of the ends 36A and 46A and the auxiliary member 8, at least the auxiliary member 8 is threaded, and by using these binders 25 and 28, the first and second connecting members 21 and 22 are made into the auxiliary member 8. Can be combined.

図9で説明したように、図4の結合具25により第1連結部材21における連結部36の補助部材8側の端部36Aを補助部材8に結合するために、それぞれの補助部材8側の端部36Aに、中心軸24の軸方向N1における互いに逆の向きの荷重W1が作用すると、補助部材8側の端部36Aの図8で示したねじり角度θ1は減少又は消滅するとともに、架け渡し部37に、荷重W1の影響による第1連結部材21の外側へ突出する方向への湾曲等の変形が生じることにより、ドア枠2側の端部36Bには、図9に示されているように、中心軸24の軸方向N1に対して第1連結部材21の内側への傾斜角度となったねじり角度θ2が生じる。 As described with reference to FIG. 9, in order to connect the end portion 36A of the connecting portion 36 on the auxiliary member 8 side of the first connecting member 21 to the auxiliary member 8 by the coupling tool 25 of FIG. When a load W1 in opposite directions in the axial direction N1 of the central shaft 24 acts on the end portion 36A, the twist angle θ1 shown in FIG. 8 of the end portion 36A on the auxiliary member 8 side decreases or disappears, and is bridged. As shown in FIG. 9, the end portion 36B on the door frame 2 side is deformed due to the deformation of the portion 37 in the direction of projecting outward from the first connecting member 21 due to the influence of the load W1. In addition, a twist angle θ2, which is an inward inclination angle of the first connecting member 21, is generated with respect to the axial direction N1 of the central axis 24.

また、図11で説明したように、図5の結合具28により第2連結部材22における連結部46の補助部材8側の端部46Aを補助部材8に結合するために、それぞれの補助部材8側の端部46Aに、中心軸27の軸方向N2における互いに逆の向きの荷重W2が作用すると、補助部材8側の端部46Aの図10で示したねじり角度θ3は減少又は消滅するとともに、架け渡し部47に、荷重W2の影響による第2連結部材22の外側へ突出する方向への湾曲等の変形が生じることにより、ドア枠2側の端部46Bには、図11に示されているように、中心軸27の軸方向N2に対して第2連結部材22の内側への傾斜角度となったねじり角度θ4が生じる。 Further, as described with reference to FIG. 11, in order to connect the end portion 46A of the connecting portion 46 on the auxiliary member 8 side of the second connecting member 22 to the auxiliary member 8 by the coupling tool 28 of FIG. 5, each auxiliary member 8 is used. When a load W2 in opposite directions in the axial direction N2 of the central shaft 27 acts on the side end portion 46A, the twist angle θ3 shown in FIG. 10 of the end portion 46A on the auxiliary member 8 side decreases or disappears, and at the same time. The end portion 46B on the door frame 2 side is shown in FIG. 11 due to deformation such as bending of the second connecting member 22 in the outwardly projecting direction due to the influence of the load W2 on the bridging portion 47. As such, a twist angle θ4 which is an inward inclination angle of the second connecting member 22 with respect to the axial direction N2 of the central axis 27 is generated.

図16及び図17には、このようなねじり角度θ2,θ4が第1及び第2連結部材21,22のドア枠2側の端部36B、46Bに生じたときを示す端部36B,46Bの拡大断面図が示されている。第1及び第2連結部材21,22の連結部36,46のドア枠2側の端部36B,46Bにねじり角度θ2,θ4が生ずると、これらのねじり角度θ2,θ4は、中心軸24,27の軸方向N1,N2に対して傾斜した角度となるため、中心軸24,27を挿通させるためにドア枠2側の端部36B,46Bに設けられた挿通部となっている第1孔38,48も、中心軸24,27の軸方向N1,N2に対して傾斜することになる。このため、第1孔38,48の角部38A,48Aは、中心軸24,27の表面に係止することになり、これを言い換えると、中心軸24,27は、第1孔38,48の角部38A,48Aが係止する被係止部材となり、この被係止部材への第1孔38,48の係止により、第1及び第2連結部材21、22は、中心軸24,27の軸方向N1,N2であるドア枠2の厚さ方向に不動状態となる。 16 and 17 show the ends 36B and 46B showing when such twisting angles θ2 and θ4 occur at the ends 36B and 46B on the door frame 2 side of the first and second connecting members 21 and 22. An enlarged cross section is shown. When twist angles θ2 and θ4 occur at the ends 36B and 46B on the door frame 2 side of the connecting portions 36 and 46 of the first and second connecting members 21 and 22, these twisting angles θ2 and θ4 become the central shaft 24, Since the angle is inclined with respect to the axial directions N1 and N2 of 27, the first hole which is an insertion portion provided at the end portions 36B and 46B on the door frame 2 side for inserting the central shafts 24 and 27. 38 and 48 are also inclined with respect to the axial directions N1 and N2 of the central axes 24 and 27. Therefore, the corner portions 38A, 48A of the first holes 38, 48 are locked to the surface of the central shafts 24, 27, in other words, the central shafts 24, 27 are the first holes 38, 48. The corner portions 38A and 48A of the above become locked members, and by locking the first holes 38 and 48 to the locked members, the first and second connecting members 21 and 22 are connected to the central shaft 24, It becomes immobile in the thickness direction of the door frame 2 which is N1 and N2 in the axial direction of 27.

このため、前述したように、壁4側の建材となっている補助部材8に対してドア枠2の厚さ方向の所定の位置に配置されていたドア枠2は、この補助部材8に、ドア枠2の厚さ方向に不動状態となって連結されることになる。 Therefore, as described above, the door frame 2 arranged at a predetermined position in the thickness direction of the door frame 2 with respect to the auxiliary member 8 which is the building material on the wall 4 side is attached to the auxiliary member 8. The door frame 2 becomes immobile in the thickness direction and is connected.

特に、本実施形態の被係止部材となっている中心軸24は、前述したように、表面にねじ山とねじ溝による凹凸が軸方向に交互に多数形成されている雄ねじ棒であるため、第1孔38,48の角部38A,48Aは、中心軸24,27の表面に一層確実に係止することになり、これにより、ドア枠2は、補助部材8に対してドア枠2の厚さ方向に一層確実に不動状態となって連結されることになる。 In particular, the central shaft 24, which is the locked member of the present embodiment, is a male screw rod having a large number of irregularities due to threads and threads alternately formed on the surface in the axial direction, as described above. The corners 38A, 48A of the first holes 38, 48 are more securely locked to the surfaces of the central shafts 24, 27, whereby the door frame 2 is attached to the auxiliary member 8 with respect to the door frame 2. It will be more reliably immobile in the thickness direction and will be connected.

また、本実施形態では、前述したように第1及び第2連結部材21、22のそれぞれ2個の連結部36,46の補助部材8側の端部36A,46Aに、結合具25,28による荷重W1,W2が作用したときには、第1及び第2連結部材21,22に設けられている架け渡し部37,47に第1及び第2連結部材21,22の外側へ突出する方向への湾曲等の変形が生じて、第1及び第2連結部材21,22のそれぞれのドア枠2側の端部36B,46Bにねじり角度θ2,θ4が生ずるとともに、架け渡し部37,47には、架け渡し部37,47の強度を低下させるための強度低下部となっている長孔40,50が設けられているため、荷重W1,W2により、架け渡し部37,47の湾曲等の変形は一層確実に生じて、ドア枠2側の端部36B,46Bのねじり角度θ2,θ4も一層確実に生じることになる。 Further, in the present embodiment, as described above, the coupling tools 25 and 28 are attached to the ends 36A and 46A on the auxiliary member 8 side of the two connecting portions 36 and 46 of the first and second connecting members 21 and 22, respectively. When the loads W1 and W2 are applied, the bridging portions 37 and 47 provided on the first and second connecting members 21 and 22 are curved in the direction of projecting outward from the first and second connecting members 21 and 22. The twist angles θ2 and θ4 are generated at the ends 36B and 46B on the door frame 2 side of the first and second connecting members 21 and 22, respectively, and the bridging portions 37 and 47 are hung. Since the elongated holes 40 and 50, which are the strength reducing portions for reducing the strength of the connecting portions 37 and 47, are provided, deformation such as bending of the connecting portions 37 and 47 is further caused by the loads W1 and W2. It will surely occur, and the twist angles θ2 and θ4 of the ends 36B and 46B on the door frame 2 side will also occur more surely.

また、本実施形態の第1及び第2連結部材21,22は、それぞれの長さ方向の両端部がドア枠2と壁4側の補助部材8とに達していて、ドア枠2の厚さ方向に離れている2個の連結部36,46と、これらの連結部36,46に架け渡された架け渡し部37,47とを有するものとなっているため、これらの第1及び第2連結部材21,22の強度は充分に大きく、このため、ドア枠2と壁4側の補強部材7とを補助部材8を介して第1及び第2連結部材21,22により連結する連結強度を充分に大きくすることができる。 Further, in the first and second connecting members 21 and 22 of the present embodiment, both ends in the length direction reach the door frame 2 and the auxiliary member 8 on the wall 4 side, and the thickness of the door frame 2 is increased. Since it has two connecting portions 36, 46 separated in the direction and connecting portions 37, 47 bridged to these connecting portions 36, 46, the first and second connecting portions 36, 46 thereof are provided. The strength of the connecting members 21 and 22 is sufficiently high, and therefore, the connecting strength for connecting the door frame 2 and the reinforcing member 7 on the wall 4 side by the first and second connecting members 21 and 22 via the auxiliary member 8 is increased. It can be large enough.
