A curtain wall unit as a panel unit that forms the outer wall of a building is attached to a building frame so that the curved surface in the three-dimensional direction of the outer wall is configured as a polyhedron having a plurality of curved surface portions obtained by dividing the curved surface. It is known. This curtain wall unit is configured by forming a frame by twisting it in the out-of-plane direction after framing the frame into a square surface, and mounting the panel on the formed twisted frame. (For example, refer to Patent Document 1).
Japanese Patent No. 3723959 Specification

  When twisting, two frame members to be joined among the rectangular frame members, for example, a vertical frame member and a horizontal frame member are joined so as to have a high strength while forming an angle in a three-dimensional direction. Difficult to do. For this reason, if the twisted frames are left in an unstable state where they are stacked on a flat place or stacked against each other, the joint between the vertical frame member and the horizontal frame member may come off or be joined. There existed a subject that the sealing material provided in the part might be damaged.

  This invention is made | formed in view of this subject, The place made into the objective is that two frame materials form the angle of a three-dimensional direction, and it can join so that it may have high intensity | strength. An object is to provide a corner member and a panel unit using the corner member.

  In order to achieve such an object, the corner member of the present invention is a corner member for joining a vertical frame and a horizontal frame constituting a frame body to which a face material is attached, and is connected to form a predetermined angle, A pair of block members inserted and fixed in the vertical frame and the horizontal frame, respectively, and an engagement member engaged with at least one of the pair of block members. The block member is brought into contact with one opposing inner surface of the two opposing inner surfaces of the inserted vertical frame or horizontal frame, and the engaging member is the other of the two opposing inner surfaces. A corner member that is brought into contact with the inner surface facing each other and is inclined in a direction along the one inner surface facing with the relative movement between the vertical frame and the horizontal frame. .

  According to such a corner member, since the pair of connected block members form a predetermined angle, the vertical frame and the horizontal frame into which the respective block members are inserted are connected to the predetermined angle. At this time, since one block material is in contact with one opposing inner surface of two sets of opposing inner surfaces of the inserted vertical frame or horizontal frame, it blocks between the inner surfaces being in contact with each other. It is possible to mount a vertical frame or a horizontal frame so that the material does not rattle. Further, since the engaging member engaged with one block member is brought into contact with the other opposing inner surface, the vertical frame or the engaging member does not rattle between the other opposing inner surfaces. It is possible to attach a horizontal frame. For this reason, the vertical frame or the horizontal frame into which one block member engaged with the engaging member is inserted is in surface contact with both the inner surface and the other inner surface. It is attached to the corner member in a stable state without any problems. Further, the engaging member moves and tilts in the direction along one opposing inner surface as the vertical frame and the horizontal frame move relative to each other, so that the engaging member moves in the direction along one opposing inner surface. It is possible to move and tilt the vertical frame or the horizontal frame in a stable state. For this reason, not only the angle in the two-dimensional direction formed by the pair of connected block members, but also the angle in the three-dimensional direction including the inclination in the direction orthogonal to the two-dimensional direction due to the movement of the engaging member, It is possible to form a vertical frame and a horizontal frame and connect them with high strength.

In this corner member, it is desirable that the pair of block members are connected so as to be rotatable about an axis in a predetermined direction.
According to such a corner member, it is possible to arrange the pair of block members so as to form an arbitrary angle in the two-dimensional direction by rotating around the axis. Further, since the pair of blocks are rotated in the connected state, it is possible to easily set the desired angle while rotating the pair of block members so as to change the angle.

In such a corner member, when the one block member is inserted into the vertical frame or the horizontal frame, the other opposing inner surface of the vertical frame or the horizontal frame and the one block member It is desirable that a gap be formed between them.
According to such a corner member, a gap is formed between the other opposing inner surface with which the engaging member is in contact and the block member, so that the vertical frame or the horizontal frame in contact with the engaging member is formed. The frame can move relative to the block member with which the engaging member is engaged in a direction in which the other inner surface faces in a range where a gap is formed. For this reason, it is possible to easily move the engaging member and the vertical frame or the horizontal frame in a direction different from the angle formed by the block members.

In such a corner member, the pair of block members and the engaging member are inserted into the vertical frame or the horizontal frame in which the shape of each joining surface is the same, while being inserted into the vertical frame and the horizontal frame. When the pair of block members are rotated and the engaging member is moved so that the joining surface of the vertical frame and the joining surface of the horizontal frame overlap each other when the vertical frame is joined, It is desirable that an angle formed between the frame and the horizontal frame is determined.
According to such a corner member, since the vertical frame and the horizontal frame form a desired angle and the shape of the joint surface is the same, the vertical frame or the horizontal frame is inserted into the block material while being inserted into the block member. By simply joining so that the joining surface and the joining surface of the horizontal frame overlap, the pair of block members are rotated and the engaging member is moved to form the vertical frame and the horizontal frame at a desired angle. Is possible. For this reason, it is possible to easily form the vertical frame and the horizontal frame accurately at a desired angle.

The panel unit is formed using the corner member.
According to such a panel unit, the vertical frame and the horizontal frame constituting the frame body to which the face material is attached are not only engaged in a two-dimensional angle formed by a pair of connected block members, but also engaged. Since it is connected with high strength so as to form a three-dimensional angle including inclination in a direction orthogonal to the two-dimensional plane by moving the member, the face material is attached so as to form a three-dimensional angle. It is possible to form a panel unit having high strength.

  According to the present invention, there are provided a corner member that can be joined so that two frame members form an angle in a three-dimensional direction and have high strength, and a panel unit using the corner member. There is an effect that can be done.

  Hereinafter, a corner member according to an embodiment of the present invention and a panel unit using the corner member will be described with reference to the drawings. In the present embodiment, a curtain wall as a panel unit in which a glass as a face material is provided on a frame having a vertical frame and a horizontal frame will be described as an example.

  As shown in FIG. 1, a building 1 in which a curtain wall 10 as a panel unit of this embodiment is used has a plurality of curtain walls 10 on an outer wall surface 1a. The outer wall surface 1a of the building 1 is curved so that the width in the depth direction of the building 1 becomes narrower when viewed from the side as shown in FIG. 3, and from the upper side as shown in FIG. When viewed, the center protrudes most and is curved so that the depth of the building 1 becomes narrower toward the left and right ends. That is, the outer wall 1a of the building 1 is attached to the housing so that the curtain wall 10 forms a polyhedron having a plurality of curved surfaces obtained by dividing the curved surface so as to image a curved surface curved in a three-dimensional direction. It has been. The plurality of curtain walls 10 constituting the wall surfaces are slightly different from each other in the angles formed by the respective frames and glass, but the configuration is the same. Therefore, in the following description, one curtain wall 10 will be described.

  As shown in FIG. 4, one curtain wall 10 is composed of a frame body 12 composed of two vertical frames 14 and two horizontal frames 16, and four sheets as face materials formed in a triangular shape. It has the glass 18 and the invisible 19 provided in the edge of glass 18 adjacent. The vertical frame 14 and the horizontal frame 16 are extruded members made of aluminum and are constituted by the same member. As shown in FIG. 5, the horizontal frame 16 has two hollow portions 16a penetrating along the longitudinal direction, and the cross section of the hollow portion 16a has a rectangular shape. Since the vertical frame 14 and the horizontal frame 16 are composed of the same member, the vertical frame 14 is also provided with two hollow portions 14a (FIG. 6) having a rectangular cross section. The two vertical frames 14 and the two horizontal frames 16 are joined by a single corner member 30 inserted into each of the hollow portions 14a and 16a.

  FIG. 5 shows a state in which the corner member 30 is mounted on the horizontal frame 16. However, the joint surface 14 b of the vertical frame 14 and the joint surface 16 b of the horizontal frame 16 have the same shape, and the joint surface of the vertical frame 14. It joins via the corner member 30 so that 14b and the joint surface 16b of the horizontal frame 16 may overlap. At this time, the vertical frame 14 is also formed by cutting from the same member as the horizontal frame 16, but the cutting angle of the vertical frame 14 and the horizontal frame 16 is the shape of the cut surface (joint surface 14b) of the vertical frame 14. When the vertical frame 14 and the horizontal frame 16 are arranged so that the shape of the cut surface (joint surface 16b) of the horizontal frame 16 coincides and the cut surfaces overlap, the vertical frame 14 and the horizontal frame 16 are predetermined. It is cut to make an angle of. A fixing portion (not shown) for fixing the curtain wall 10 to the housing of the building 1 is provided inside the building 1 in the frame body 12.

  Next, the corner member 30 will be described. In the following description, for convenience of description, the vertical frame 14 and the horizontal frame 16 will be described as square pipes. As shown in FIGS. 6 to 8, the corner member 30 of the present embodiment includes two block members 32 inserted into the hollow portion 14 a of the vertical frame 14 and the hollow portion 16 a of the horizontal frame 16, and each block member 32. Two engaging members 34 engaged with each other, and an annular shaft body 36 for rotatably connecting the two block members 32. The two block members 32 and the two engaging members 34 constituting one corner member 30 are the same member. Further, the block member 32, the engaging member 34, and the annular shaft body 36 are all made of, for example, aluminum.

  The block member 32 is formed long in the insertion direction to the vertical frame 14 or the horizontal frame 16, and has a rectangular block-shaped main body portion 32 a and a connecting portion 32 b for connecting the two block members 32. ing. The connecting portion 32b is provided so as to extend from the main body portion 32a, and a fitting portion 32c into which the annular shaft body 36 is fitted is formed. The connecting portion 32b is divided at a portion opposite to the main body portion 32a. Further, the outer periphery of the connecting portion 32b is formed in an arc shape concentric with the insertion portion 32c into which the annular shaft body 36 is inserted, except for the portion 32e connected to the main body portion 32a and the divided portion 32d. Since the two block members 32 are rotated by inserting the annular shaft body 36 into the insertion portion 32c of the connecting portion 32b, the direction in which the insertion portion 32c is penetrated is when the two block members 32 rotate relative to each other. This is the axial direction. Further, the connecting portion 32b is provided with a through hole 32f penetrating toward the center of the fitting portion 32c. The through-hole 32f is penetrated by a screw for fixing the annular shaft body 36 at a position where the annular shaft body 36 is inserted and the two block members 32 are set in the rotation direction at a set angle.

  The main body 32a is provided with a rectangular opening 32g penetrating in the axial direction in which the block member 32 rotates. The opening 32g is formed so that the engaging member 34 can be inserted and moved in the axial direction. The rectangular opening 32g of the main body portion 32a connects the base portion 32h on the connecting portion 32b side, the tip portion 32k having the inner surface 32j facing the inner surface 32i of the base portion 32h, the base portion 32h, and the tip portion 32k, and is a block material. It has two plate parts 32n which the inner surface 32m opposes in 32 rotation directions. The distance L1 between the outer surfaces 32o of the two plate portions 32n is a distance between the two opposing inner surfaces 14c, 14d, 16c, and 16d of the vertical frame 14 or the horizontal frame 16 having a rectangular shape into which the block member 32 is inserted. Is substantially coincident with the interval L2 between the inner surfaces 14c, 16c facing each other. Further, the width L3 in the axial direction of the two plate portions 32n is such that the two sets of opposed inner surfaces 14c, 14d, 16c, 16d of the vertical frame 14 or the horizontal frame 16 that form the rectangular shape into which the block member 32 is inserted. It is formed narrower than the distance L4 between the inner surfaces 14d, 16d facing each other.

  One of the two plate portions 32n of the main body portion 32a is provided with a hole 32p through which a screw for fixing the vertical frame 14 or the horizontal frame 16, the block member 32 and the engaging member 34 passes. . For example, three holes 32p are provided side by side in a direction orthogonal to the axis. Further, the width of the main body portion 32a in the axial direction is about twice the width of the connecting portion 32b in the axial direction. Then, the connecting portions 32b of the two block members 32 are arranged so that the positions in the axial direction with respect to the main body portion 32a are different and overlapped in the axial direction, and the annular shaft body 36 is fitted to the fitting portions 32c of the two block members 32. The two block members 32 are connected by being inserted.

  The engaging member 34 is a square pipe member made of aluminum or the like having a rectangular cross section. The distance between the outer surfaces of the opposing side plate portions 34a of the two pairs of side plate portions 34a, 34b of the rectangular engagement member 34 is substantially equal to the distance between the inner surfaces 32m of the plate portions 32n of the block member 32. The distance between the outer surfaces of the opposing side plate portions 34b of the two pairs of side plate portions 34a and 34b formed by the engaging member 34 is inserted together with the block member 32 with which the engaging member 34 is engaged. Of the two opposing inner surfaces 14c, 14d, 16c, and 16d of the vertical frame 14 or the horizontal frame 16 that form a rectangular shape. The length of the engagement member 34 in the longitudinal direction is shorter than the distance between the inner surface 32 i of the base portion 32 h of the block member 32 and the inner surface 32 j of the tip end portion 32 k. For this reason, when the engagement member 34 is inserted into the block member 32, the engagement member 34 is engaged so that one side plate portion 34a of the engagement member 34 contacts the inner surface 32m of the two plate portions 32n of the block member 32. In the engaged state, the block member 32 is configured to be movable and swingable in the direction along the inner surface 32m of the two plate portions 32n.

  Then, in a state where the corner member 30 is assembled, the two block members 32 rotate in the two-dimensional direction around the annular shaft body 36, and the engaging members 34 engaged with the respective block members 32 are the block members. Independent of the rotational movement of 32, the block member 32 can move and swing in the direction along the inner surface 32m of the two plate portions 32n.

  A method of joining the vertical frame 14 and the horizontal frame 16 using the corner member 30 of the present embodiment will be described. Here, an example in which the corner member 30 is fixed first from the horizontal frame 16 will be described. Moreover, as for the vertical frame 14 and the horizontal frame 16 which are joined, the edge part joined is cut | disconnected so that the vertical frame 14 and the horizontal frame 16 may be joined at a desired angle, respectively. That is, when the vertical frame 14 and the horizontal frame 16 are arranged at a desired angle, the vertical frame 14 and the horizontal frame 16 are arranged such that the cut surface 14b of the cut vertical frame 14 and the cut surface 16b of the horizontal frame 16 overlap. And has been processed. Further, the vertical frame 14 to be attached later to the corner member 30 has a screw at a position overlapping the hole 32p provided in the block member 32 when the vertical frame 14 and the horizontal frame 16 are arranged at a desired angle. An insertion hole 14e to be inserted is formed in advance.

  First, the block member 32 and the annular shaft 36 are fixed with a screw that passes through the through hole 32 f of one block member 32 of the corner member 30.

  Next, the block member 32 fixed to the annular shaft body 36 is inserted into the horizontal frame 16 in a state where the engagement member 34 is engaged, and the insertion hole 16e provided in the horizontal frame 16 and the block member 32 are provided. The prepared hole 32p is aligned and a pilot hole is formed in the engaging member 34 engaged with the block member 32 using a drill or the like. A screw that penetrates the horizontal frame 16 and the block member 32 is screwed into and fixed to the formed lower hole. At this time, the horizontal frame 16, the block member 32, and the engaging member 34 are all arranged in parallel along the longitudinal direction.

  Then, the other block member 32 in a state where the engaging member 34 is engaged is inserted into the vertical frame 14. At this time, if the joining surfaces 14b and 6b of the vertical frame 14 and the horizontal frame 16 are formed so that the vertical frame 14 and the horizontal frame 16 are inclined only in the two-dimensional direction, as shown in FIG. The vertical frame 14, the horizontal frame 16, and the corner member 30 are arranged on the front side. Here, the vertical frame 14 is joined while moving the vertical frame 14 in which the block member 32 and the engaging member 34 are inserted so that the vertical frame 14 forms a predetermined angle with respect to the horizontal frame 16. The vertical frame 14 is moved so that the surface 14b and the joint surface 16b of the horizontal frame 16 overlap. When the vertical frame 14 is moved in this manner, the two block members 32 are rotated in a two-dimensional direction, and the engaging member 34 that is in contact with a pair of inner surfaces 14d of the vertical frame 14 is moved together with the vertical frame 14. Is done. At this time, since the vertical frame 14 and the block member 32 have a gap L (La + Lb) in the axial direction, the vertical frame 14 and the vertical frame 14 are in axial contact with each other in the range of the gap L. The combined member 34 moves relative to the block member 32. That is, the engaging member 34 moves in a direction along one opposing inner surface 14c of the vertical frame 14 with which the block member 32 is in contact, and is inclined as shown in FIG. 9B.

  Then, after the joining surface 14b of the vertical frame 14 and the joining surface 16b of the horizontal frame 16 overlap each other and the vertical frame 14 and the horizontal frame 16 form a desired angle, the vertical frame 14 is maintained while maintaining the formed angle. Is moved in a direction away from the horizontal frame 16, and the connecting portion 32b of the block member 32 inserted into the vertical frame 14 and the annular shaft body 36 are fixed with screws. Thereafter, the vertical frame 14 is returned and the vertical frame 14, the block member 32, and the engaging member 34 are screwed and fixed so that the joint surface 14 b of the vertical frame 14 and the joint surface 16 b of the horizontal frame 16 overlap each other. . Thereafter, a sealing material (not shown) is filled between the joint surface 14 b of the vertical frame 14 and the joint surface 16 b of the horizontal frame 16.

  According to the corner member 30 of the present embodiment, the pair of connected block members 32 rotate around the annular shaft body 36 to form a predetermined angle, so that an arbitrary angle is formed in the two-dimensional direction. It is possible to arrange the vertical frame 14 and the horizontal frame 16. At this time, since the pair of block members 32 rotate in a connected state, it can be easily set to a desired angle while rotating to change the angle between the vertical frame 14 and the horizontal frame 16. .

  Further, the block member 32 is inserted into the vertical frame 14 or the horizontal frame 16 with the engaging member 34 engaged, and two sets of opposed inner surfaces 14c, 14d, 16c of the inserted vertical frame 14 or horizontal frame 16 are opposed. , 16d, two plate portions 32n of the block member 32 are in contact with one opposing inner surface 14c, 16c. For this reason, the block material 32 is mounted without rattling between the vertical frame 14 or the horizontal frame 16 on the inner surfaces 14c and 16c side in contact with each other. Further, since the engaging member 34 engaged with each block member 32 is in contact with the other opposing inner surfaces 14d, 16d of the vertical frame 14 or the horizontal frame 16, on the other opposing inner surfaces 14d, 16d side. The vertical frame 14 or the horizontal frame 16 is attached to the engaging member 34 without rattling. For this reason, the vertical frame 14 or the horizontal frame 16 into which the block member 32 and the engaging member 34 are inserted has a backlash on both the inner surfaces 14c and 16c facing each other and the inner surfaces 14d and 16d facing each other. It is possible to form the frame 12 having a high rigidity while maintaining a stable state without being attached.

  Further, the engaging member 34 is moved and inclined in the direction along the one opposing inner surface 14c, 16c as the vertical frame 14 and the horizontal frame 16 move relative to each other, so that the block member 32 and the engaging member It is possible to move the vertical frame 14 and the horizontal frame 16 in which 34 is inserted in the axial direction while maintaining a stable connection state. For this reason, the vertical frame 14 and the horizontal frame 16 are not only two-dimensional angles formed by a pair of connected block members 32 but also a direction orthogonal to the two-dimensional direction due to the movement of the engaging member 34. It is possible to connect with high strength so as to form a three-dimensional angle that also includes a tilt to the right.

  At this time, since the gap L is formed between the other opposing inner surfaces 14d and 16d of the vertical frame 14 and the horizontal frame 16 with which the engagement member 34 is in contact with the block member 32, the engagement member The other inner surfaces 14d and 16d of the vertical frame 14 or the horizontal frame 16 in contact with 34 are opposed to the block member 32 with which the engaging member 34 is engaged within the range where the gap L is formed. It is possible to move relative to the direction of movement. For this reason, it is possible to easily move the engaging member 34 and the vertical frame 14 or the horizontal frame 16 in a direction different from the angle formed by the two connected block members 32.

  Further, when the vertical frame 14 and the horizontal frame 16 form a desired angle, the vertical frames 14 and the horizontal frame 16 formed so that the joint surfaces 14b and 16b of the vertical frame 14 and the horizontal frame 16 overlap each other. By simply joining the vertical frame 14 and the horizontal frame 16 while inserting the block material 32 and the engagement member 34, the pair of block materials 32 are rotated together with the vertical frame 14 and the horizontal frame 16, and the engagement member 34 is further moved. The vertical frame 14 and the horizontal frame 16 can be joined at a desired angle. For this reason, the vertical frame 14 and the horizontal frame 16 can be easily formed accurately at a desired angle.

  Further, according to the curtain wall 10 using the corner member 30, the vertical frame 14 and the horizontal frame 16 constituting the frame 12 to which the glass 18 is attached are formed by a pair of connected block members 32. In addition to the angle in the two-dimensional direction, the engagement member 34 is connected with high strength so as to form a three-dimensional angle including an inclination in a direction orthogonal to the two-dimensional direction by moving the engagement member 34. Thus, the curtain wall 10 to which the glass 18 is attached can be realized, and is suitable as an outer wall material of the building 1 in which the outer wall looks like a curved surface.

  In the above-described embodiment, an example in which one block member 32 of the corner member 30 is fixed to the horizontal frame 16 and then the vertical frame 14 is moved and joined to form a desired angle has been described. After the block member 32 is fixed, the horizontal frame 16 may be moved and joined to form a desired angle. Moreover, although the example which fixed so that the horizontal frame 16, the block material 32 inserted in the horizontal frame 16, and the engaging member 34 engaged with the block material 32 may become parallel to a longitudinal direction was demonstrated. The frame 14, the block material 32, and the engagement member 34 may be fixed so as to be parallel to the longitudinal direction, and both the vertical frame 14 and the horizontal frame 16 are parallel to the block material 32 and the engagement member 34. It may be fixed so that it does not become.

  Moreover, in the said embodiment, although the example in which the two block materials 32 were connected rotatably was demonstrated, when connecting each to the connection part of the two block materials 32, as shown in FIG. An abutting surface 32r to be abutted is formed, and the abutting surface 32r is overlapped with the abutting surfaces 32r of the two block members 32 in the same manner as the vertical frame 14 and the horizontal frame 16. The two block members 32 may be formed at a desired angle.

  In the above embodiment, the block member 32, the engaging member 34, and the annular shaft 36 are all made of aluminum, but the present invention is not limited to this. Further, although the vertical frame 14 and the horizontal frame 16 have been described as hollow members having a rectangular cross section, the vertical frame 14 and the horizontal frame 16 have a configuration in which the block member 32 and the engaging member 34 are in contact with each other and do not rattle. The cross section of the frame 16 may be a polygonal shape such as a hexagonal shape or an octagonal shape.

  In the above embodiment, the engaging member 34 is a square pipe material, but it may be a solid block material 32. Furthermore, the engaging member 34 is in contact with the opposing inner surface 32m of the two plate portions 32n in the block member 32, and is a set of opposing inner surfaces that are not in contact with the block member 32 in the vertical frame 14 or the horizontal frame 16. The cross-sectional shape orthogonal to the direction of insertion into the vertical frame 14 or the horizontal frame 16 may be a U shape, an H shape, or the like as long as it is in contact with 14d, 16d.

  Furthermore, in the said embodiment, although the panel unit was demonstrated as the curtain wall 10, you may be a sash window by which glass was attached to the frame.
