[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting structure of members using a vertical structure, such as a structure in which a front grid beam and a side grid beam are connected by using a cube.

[0002]

[Prior art]

 In a structure in which front and side members are connected via a vertical structure such as handrails and bay windows that project from the wall of a building, both front and side members and a corner piece are combined when connecting the vertical members. Used by members.

The connecting member has a function of firmly connecting the above three members to each other at a predetermined angle, but it requires skill and is poor in workability to be attached so as to prevent looseness or gaps or misalignment. . Furthermore, in order to conceal the heads of the screws that fix the connecting member and the above three members, a face plate is also attached to the front side, which is necessary for the design, such as the elegant texture of the material surface such as the upright. There is a case that the requirements to be impaired.

Further, as shown in FIG. 5, the conventional surface lattice 1 is often attached to a wall surface of a building by a simple bracket 2. Such a structure is a result that attaches importance only to the appearance from the front of the area lattice 1, and there is an unsightly surface from the appearance of the building in which the side surface of the area lattice 1 can be seen.

On the other hand, due to the diversification of users, the surface lattice 1 is required to have a volume feeling and a solid feeling. However, it is difficult to obtain such a thing with the structure using the conventional bracket. Conventionally, there is also a structure in which the side surface is taken out from the wall surface of the building as shown in Fig. 6, but this structure is, so to speak, a plane lattice formed only by the lattice crosspieces 3, and therefore a structure with sufficient strength can be obtained. difficult.

[Problems to be Solved by the Invention] The object of the present invention is to provide a connection structure that is easy to assemble and is easy to obtain a neat and elegant appearance, and is structurally robust.

[0007]

[Means for Solving the Problems]

 The present invention relates to a member connecting structure in which a front member and a side member are connected to each other via a vertical direction. Both ends of the front member are angled for a fastening connection. In the cross section, the vertical surface has a first surface which is brought into contact with the end surface of the front member to form a fastening connection and a second surface which is brought into contact with the end surface of the side surface member to be joined. When the end face of the front member is brought into contact with the first face and screwed, a screw for fixing the side member whose end face is brought into contact with the second face is secured in a range hidden by the end face of the front member. An insertion hole for inserting and screwing from the front side is formed.

[0008]

[Action]

 The insertion hole formed in the first surface allows the side member to be screwed to the second surface, and the screw head is hidden by the front member attached to the first surface. The configuration in which the front member and the side member are screwed to the upright enables them to be directly connected without using a connecting member.

【Example】

 1 to 4 relate to an area grating 1. As shown in FIG. 4, the surface lattice 1 is composed of a front member 4, side surface members 5 and uprights 6. The enlarged portion A surrounded by a circle has a joined structure in which the front member 4, the side member 5 and the upright 6 are joined together.

The front member 4 is composed of upper and lower frames 7 and 8 and a plurality of laterally arranged lattice bars 9, and the side member 5 is similarly composed of upper and lower frames 10 and 11 and the above-mentioned lattice. It is composed of the same number of horizontal rails as the horizontal rails 9 and the mounting frames 13. The mounting frame 13 is a vertical member that fixes the inner side ends of the lower frames 10 and 11 and the lattice bars 12 on the side surface.

The cubic 6 is formed by crossing an aluminum alloy extruded material, and has a right-angled triangle as a whole in a cross section, and the surface corresponding to the hypotenuse is the end of the front member 4. The surface corresponding to the bottom side is the second surface 15 to which the outdoor side of the side member 5 is attached. The first surface 14 has an angle of 45 ° with respect to the second surface 15. This is because the connection with the front member 4 is to be a fixed connection.

In addition, a hollow portion 16 for reinforcement and an indoor decorative portion 17 for concealing an indoor corner of the combined structure are formed on the bottom side 15, and further, a third side corresponding to a vertical side in cross section is formed. The corner portion formed by the surface 18 and the first surface 14 is formed into a round shape with an arc, and serves as an outdoor decorative portion 19.

On the first surface 14, screws 20 for connecting the upper and lower frames 7 and 8 on the front side and the ends of the lattice bars 9 on the front side are in contact with the frame 6 and the bars 6 to the upright 6. Is formed with a screw seat 21 and an insertion hole 22. The screw seat 21 is formed by forming a screw hole in the left-right direction in a ridge formed during extrusion molding. The insertion hole 22 has a sufficient size for inserting a tool such as a screwdriver at a position where the second surface 15 can be seen from the front side. Reference numeral 23 is a low edge, which is formed on both sides of the first surface 14.

The second surface 15 is provided with these frames and bars at the front position of the insertion hole 22 within a range where the upper portions of the side surfaces, the lower frames 10, 11 and the end portions of the lattice bars 12 come into contact with each other. A screw hole is formed for the screw 24 which is connected to the upright 6. In addition, low protruding edges 23 are formed on both sides of the outer wall of the hollow portion 16 of the second surface 15. An insertion gap 25 is formed on the third surface 18 at the front position (as viewed from the side) of the screw seat 21, and the eye plate 26 can be attached thereto. This gap 25 is formed as a slit during extrusion molding.

FIG. 1 and FIG. 2 show a procedure for connecting the front member 4 as a member, the side member 5 and the upright 6 to form a combined structure, and relates to the assembling of the portion A surrounded by a circle in FIG. These are assembled as follows. In this embodiment, a sheet metal reinforcing metal member 27 having a substantially V shape and having screw holes is used by being attached to the inner surfaces of the first surface 14 and the second surface 15.

The outer wall of the upper hollow portion 16 of the upright 6 is cut out by the height of the upper frame 10 on the side surface (FIG. 2). The end of the side frame 10 connected to the upright 6 is crossed on a vertical plane at right angles to the longitudinal direction.

The end portion of the upper frame 10 is inserted into the cutout portion, a screw 24 is inserted from the front side of the insertion hole 22 in the first surface 14, and the upper portion is passed through the reinforcing metal fitting 27 and the screw hole of the second surface. Screw it into the screw hole of the frame 10. Thereby, the upper frame 10 on the side surface is fixed to the upright 6. Reference numeral 28 is an eye plate for the upper frame 10.

Then, both ends of the front upper frame 7 and the lattice bar 9 are cut at 45 ° in plan view for fastening and the end faces are brought into contact with the first face 14. As a result, the insertion hole 22 exposed on the first surface 14 and the head of the screw 24 that fixes the side upper frame 10 are hidden by the upper frame 7. From the insertion gap 25 of the third surface 18, the screw 20 is screwed into the screw hole of the front upper frame 7 through the reinforcing metal fitting 27 and the screw hole of the first surface, and the front upper frame 7 is fixed to the upright 6. Be done.

The eye plate 26 is attached to the insertion gap 25. The cap 29 is attached to the top of the upright 6 from above. The cap 29 is made of aluminum die cast in this embodiment.

As a result, the three members of the front upper frame 7, the side upper frame 10, and the upright 6 are directly joined by screws without using a joining member such as a corner piece. The reinforcing metal fitting 27 in the above-described embodiment is not a connecting member because it does not have a function of connecting the two members by interposing them.

In this joint structure, the front member 4 and the side member 5 are directly joined by screws via the uprights 6, so that the assembling work is easy. Further, the insertion hole 22 exposed on the front side and the head of the screw 24 to which the side member 5 is fixed are automatically hidden when the front member 4 is fixed. No, the appearance of the combined structure is neat.

In the above-described embodiment, when the side grid rails 12 are connected to the upright 6, the ends to be connected are traversed similarly to the case of the side upper frame 10, and the first surface 14 is inserted. Screw through the hole 22. Further, when the front lattice bar 9 is connected to the upright 6, both ends are cut at 45 ° for fastening and are inserted from the insertion gap 25 of the third surface 18, as in the case of the front upper frame 7. Secure with extra screws.

That is, in the surface lattice 1, the front member 4 composed of the upper and lower frames 7 and 8 and the plurality of lattice bars 9 is fixed to the uprights 6 and 6 on both sides in this way, and further, in this embodiment, the upper and lower sides are arranged. The frame members 10 and 11 are formed by connecting side members 5 and 5 which are composed of a plurality of lattice bars 12 and a mounting frame 13 in which these indoor ends are connected.

The surface lattice 1 formed in this way has a frame structure on both the front and side surfaces, and since it is integrally connected by sharing the cubic 6, the strength is high. On the other hand, both ends of each of the lattice bars 9 and 12 are directly connected to the upright 6, and the vertical members are provided at the corners as in the case where the preassembled surface lattices are connected to the upright 6. There is no duplication and there is a sense of unity as a whole. Further, since the above-mentioned member coupling structure is adopted, the eye plate and the like are not exposed on the front side.

The interior decorative portion 17 hides the joint between the front member 4 and the side member 5 through the erection 6 and gives a thick feeling to the corners that are the entering corners. The outdoor decorative portion 19 has a rounded corner at the corner connecting the front member 4 to the side member 5 to give the members 4 and 5 a solid and solid feel. Further, the projecting edge 23 on the first surface 14 and the second surface 15 swallows the end surfaces of the members abutting on these surfaces, and hides the joint between the upright 6 and these members. As a result, some gaps and misalignments during assembly are hidden.

The above is an embodiment, and the present invention is not limited to the illustrated specific configuration. The cross section of the cubic 6 is not limited to the one based on a triangle, but when the side member 5 is also fastened and coupled, the cross section structure is such that the first surface 14 and the second surface 15 are parallel. Sometimes. The angle at which the end portions of the front surface member 4 and the side surface member 5 contact the upright 6 may be other than 45 °. The front surface member 4 and the side surface member 5 may be other than the surface lattice 1.

[0027]

[Effect of device]

 The most conspicuous front side does not show the members that tend to spoil the design, such as the eye plate, and it is possible to obtain a member connection structure with a clean appearance. Since the connecting member is not used for the assembling, the assembling work is easy.

Since the front member and the side member are directly connected to the cuboid, they are structurally strong and, at the same time, there is no overlapping of the frame members at the cuboid portions, and an elegant design is easy.
