DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for a bridge member provided at a corner or the like of, for example, a handrail provided on a balcony, indoor / outdoor stairs, a rooftop, or the like, or a rim of a fence.

[0002]

2. Description of the Related Art Conventionally, as a connecting device of this kind of erection member, a connecting device described in Japanese Patent Application Laid-Open No. 8-302632 applied to a handrail such as a stair is known. The connecting tool used for the handrail includes a connecting tool body fixed to the upper end of the column, a first connecting piece rotatably attached to the connecting tool body in a vertical direction, and a first connecting piece. On the other hand, it comprises a second connecting piece rotatably mounted in the horizontal direction. And one handrail bar is connected to the first connecting piece,
The other handrail bar is connected to the second connecting piece. In this connection mode, the end of the handrail bar is inserted into the cylindrical portion of each connecting piece, and a male screw is screwed into a screw hole formed in the handrail bar from the outside of the cylindrical portion and fixed.

[0003]

With handrails of this type, both indoors and outdoors, it is impossible to construct a pillar standing on a foundation with high precision like a mechanical device. In actual construction, after the connecting tools are attached to the columns, the handrail bars are cut and adjusted at the site in accordance with the dimensions between the connecting tools. Therefore, as described above, in the conventional connecting device, it is easy to attach the connecting tool to the column, but when attaching the handrail bar to the connecting tool, it is necessary to cut the handrail bar with extremely high accuracy even at the site. Further, it is necessary to form a screw hole with extremely high precision in the handrail bar. Specifically, if the handrail bar is long, it cannot be mounted on the connecting tool, and if it is short, the screw hole cannot be formed. Of course, since the angle adjustment of the first connecting piece and the second connecting piece of the connecting tool needs to be performed after the handrail bar is finally mounted, a situation may occur in which the dimensions do not match after the handrail bar is mounted. . Therefore, the workability was poor. In addition, there is a problem that a step is generated at a connecting portion between the connecting tool and the handrail bar, so that the appearance is deteriorated.
Of course, if a step portion corresponding to the thickness is formed on either of the two, the step can be eliminated, but in this case, the dimensional accuracy of the handrail bar is further required, and the construction becomes impossible.

It is an object of the present invention to provide a connecting device for a bridge member, which can be easily and dimensionally adjusted and which can be finished well in design.

[0005]

According to the present invention, there is provided a connecting device for a bridge member, comprising: a connecting member for connecting one of the building members to the other member. A connector body attached to the upper end of the connector body, one end of which is rotatably attached to the connector body in a vertical direction, and one of the bridging members is attached to the other end at an arbitrary position in an extending direction away from the end face. A possible connecting piece for inclination, and one end is attached rotatably in the horizontal direction to the connecting tool body,
The other end is provided with a bending connecting piece to which the other bridging member can be attached at an arbitrary position in an extending direction away from the end face.

According to this structure, one of the connecting pieces for inclination is rotatably mounted in the vertical direction, and the other connecting piece for bending is rotatable in the horizontal direction with respect to the connecting body mounted on the support. Since it is attached, it is possible to cope with a two-dimensional connection part such as a part transitioning from horizontal to inclined (inclination to horizontal) or a corner part when a plurality of erection members are connected to form a handrail or the like. Along with the transition from the slope to the corner (from the corner to the slope)
It is possible to cope with dimensional connection parts. Also, each connecting piece is configured to be able to attach the erection member at any position in the extending direction away from its end face, that is, the connecting piece supports the erection member at a position away from its end face. Therefore, the dimension of the erection member is not restricted by the connecting piece (connecting tool), but by the end of the erection member connected thereto. Therefore, in the construction of handrails, etc., as long as the erection members are sequentially assembled in the extending direction thereof, the end surfaces of the erection members are reliably abutted against each other or a certain gap exists without cutting the erection members with high accuracy. And confront each other. In addition, since the end faces of the erection member are brought into contact with each other or face each other, a neat connection form can be obtained.

In this case, there is further provided an auxiliary connecting tool for connecting the tip of one of the erection members and the tip of the other erection member,
The auxiliary coupler is attached to the tip of one of the erection members,
A male auxiliary connection member having a connection projection formed on a spherical surface,
It is preferable that a female auxiliary connecting member having a connecting concave portion having a complementary shape to the connecting convex portion is attached to the tip of the other bridge member.

According to this structure, the connecting convex portion of the male auxiliary connecting member is formed in a spherical surface, and the corresponding connecting concave portion of the female auxiliary connecting member is formed in a complementary shape to the connecting convex portion. Regardless of the angle at which one of the erection members to which the male-side auxiliary connection member is attached and the other erection member to which the female-side auxiliary connection member is attached abuts, The erection member and the other erection member can be connected. That is, as if one erection member and the other erection member were connected via a spherical joint,
Can be finished to design.

In another aspect of the present invention, there is provided a connecting device for a bridge member having a connecting member for connecting one of the mounting members to the other member. And a connecting member body attached to the portion, each of which has one end attached rotatably in the vertical direction to the connecting member body, and each of the bridging members attached to the other end at an arbitrary position in an extending direction away from the end surface thereof. And a possible pair of connecting pieces.

According to this structure, since the pair of connecting pieces are respectively rotatably mounted in the horizontal direction with respect to the connecting body mounted on the support, a plurality of erection members are connected to form a handrail or the like. In this case, it is possible to cope with a portion that transitions from horizontal to inclined (from inclined to horizontal), in addition to a linear connection portion. In particular, the structure can be simplified, and even if it is a linear connecting part in design,
Even if the two erection members are not straight due to the height of the support column, this can be absorbed by changing the opening angle of the pair of connecting pieces. In addition, since each connecting piece is configured so that the erection member can be attached at any position in the extending direction away from the end face, the end faces of the erection member can be securely connected without cutting the erection member with high accuracy. , Or confront each other with a certain gap. In addition, the end faces of the erection members can be connected in a neat manner.

In these cases, the connecting member main body has a fitting portion fitted to the upper end portion of the column, and a screw screwed into the column from outside is engaged with the outer peripheral portion of the fitting portion. It is preferable that an annular groove is formed.

According to this structure, when the connecting member main body is fitted to the column from above and a screw is screwed into the column from the outside, the screw engages with the fitting portion and the connecting member main body is pulled out of the column. Fixed in the stopped state. In this case, since the portion of the fitting portion with which the screw engages is an annular groove, the screw can be reliably engaged with the annular groove no matter where the screw is attached in the circumferential direction of the column. Therefore, the screws that can be seen from the outside can be provided in the least noticeable places.

The female auxiliary connecting member 52 has the same external shape as the main body 53 of the male auxiliary connecting member 51, and has a connecting concave portion 55 formed at the tip thereof in a complementary shape to the connecting convex portion 54.

Therefore, the connecting concave portion 55 and the connecting convex portion 54
When they are joined so as to abut each other, a connection form is obtained as if one handrail bar 4 and the other handrail bar 4 were joined via a spherical joint. In this case, since the connecting concave portion 55 and the connecting convex portion 54 are in contact with each other on a spherical surface, the connecting concave portion 55 and the connecting convex portion 54 are in close contact with each other regardless of the angle at which the handrail bars 4 and 4 are connected. For this reason, two-dimensional and three-dimensional joining (butting) that does not cause a sense of incongruity can be achieved by using the auxiliary connecting tool 5.

Here, the construction procedure around the oblique connector 3a will be briefly described. First, the connecting piece 13 for bending is attached to the connecting tool main body 11 and the cap assembling screw 23 is temporarily tightened, and this is fitted to the upper end of the column 2 and screwed. Next, after adjusting the angle of the bending connecting piece 13, the cap assembling screw 23 is fully tightened. Next, the connecting piece for inclination 12 is connected to the connecting tool body 1 using the connecting piece mounting screw 25.

The support portions 33 are aligned with each other, and the support portions 33 are temporarily fastened to the back plate 6 with the mounting screws 15. When the positional relationship between one handrail bar 4 and the inclined connecting piece 12 is determined, the connecting piece mounting screw 2
5 and this mounting screw 15 are fully tightened, and one handrail bar 4
Complete the installation. Finally, the male auxiliary connecting member 51
Is attached to the back plate 6 of the other handrail bar 4 on which the
After the positioning of the supporting portion 43 of the third handrail bar 4, the supporting portion 43 is temporarily fastened to the back plate 6 with the mounting screw 15.
Is slid so that the male auxiliary connecting member 51 abuts against the female auxiliary connecting member 52, and then the mounting screw 15 is fully tightened.
In the case of assembling from the right side of the drawing, the bending connecting piece 13 is first fully tightened, and the female auxiliary connecting member 52 is abutted against the male auxiliary connecting member 51.
Fully tighten the two sides.

As described above, the oblique connection member 3a of the embodiment
According to this, the connecting piece for inclination 12 is attached to the connecting body 11 so as to be rotatable in the vertical direction, and the connecting piece for bending 13
Are rotatably mounted in the horizontal direction, so that the adjacent handrail bars 4, 4 are connected by being inclined in the vertical direction,
The present invention can be applied to a part which is connected by being bent in a horizontal direction, a part which is inclined in a vertical direction and is connected by being bent in a horizontal direction, and the like. The connecting piece 12 for inclination and the connecting piece 13 for bending extend in a “V” shape around the connecting tool main body 11, and both support the handrail bar 4 at a position away from its end face. Therefore, the mounting position of each handrail bar 4 to each of the connecting pieces 12 and 13 is not restricted by the length of the handrail bar 4. That is, since the length of the handrail bar 4 is only limited by the position of the end face (actually, the auxiliary connecting tool 5) of the adjacent handrail bar 4, by sequentially constructing the handrail bar 4,
The dimensional accuracy of the handrail bar 4 is not required, and the workability can be improved.

In addition, apart from the inclined connecting member 3a, an auxiliary connecting member 5 having a spherical contact surface at the abutting portion of the handrail bars 4, 4 is provided. Even if they are connected at an appropriate angle, their continuity and design can be improved. Note that the oblique connection tool 3a and the auxiliary connection tool 5 can also be used in a portion where the handrail bars 4 and 4 are connected linearly.

Next, the intermediate connector 3b will be described with reference to FIG. The intermediate connecting tool 3b is different from the oblique connecting tool 3a in that the bending connecting piece 13 is replaced with the inclined connecting piece 12.
Is provided. Specifically, the intermediate connector 3
b of the connector body 1 of the oblique connector 3a.
1, and a ring 61 having the same shape as the annular base 41 of the bending connecting piece 13 is mounted on the mounting portion 24 thereof. Left and right inclined connecting pieces 12, 1
Reference numeral 2 denotes a separate body, and each base 31 is rotatably attached to the connector main body 11 via a connection piece mounting screw 25. In this case, the left and right inclined connecting pieces 12, 1
2 has the same form (however, it is preferable that one of the holes formed in the base portion 31 is a fool hole and the other is a screw hole), and is attached so that the left and right are inverted to form a “V” shape. ing. For this reason, the base portions 31, 31, which are portions where the two inclined connecting pieces 12, 12 are overlapped, each have a half cutout so as to be half the width of the arm portion 32.

The intermediate connector 3b thus configured is
As shown in FIG. 1, it is provided to support an intermediate position or a position near an end of one handrail bar 4. In this case, the left and right inclined connecting pieces 12, 12 do not need to be configured to be rotatable with respect to the connecting tool body 11, respectively, and the left and right inclined connecting pieces 12, 12 may be integrally formed. Good, but by separating them, handrail bars 4, 4 as shown in FIG.
The present invention can also be effectively applied to a part where they are connected linearly or a part where they are connected while being inclined in the vertical direction.

For example, in FIG. 6, if the height of the support column 2 is higher than the design size, the left and right inclined connecting pieces 12 can be opened to open the two handrail bars 4. , 4 can be lowered to absorb the dimensional error of the column 2. On the other hand, if the height of the column 2 is lower than the design dimension, the left and right inclined connecting pieces 12 can be closed so that the position of the connecting portion of the handrail bars 4 can be adjusted. And the dimensional error of the support column 2 can be absorbed. Therefore, even if the column 2 is not accurately constructed at the height, the linearity of the adjacent handrail bars 4 can be ensured.

A small cap may be attached to the end of the handrail bar in place of the auxiliary connecting tool so that the ends of the handrail bar face each other in an unconnected state. Furthermore, it goes without saying that the connecting device of the present invention can be widely applied to connecting portions of erection members in architecture and civil engineering, in addition to handrails.

[0029]

As described above, according to the connecting device of the erection member of the present invention, it is possible to cope with a three-dimensional connection part and the erection member is required to have dimensional accuracy in its length direction. Therefore, the workability at the site can be improved. In addition, it is possible to achieve a good finish without inferior in design.

Further, according to the other connecting device of the bridging member of the present invention, it is possible to cope with a bent connecting portion in addition to a linear connecting portion with a simple structure. In addition, irregularities in the height of the columns during construction can be easily absorbed.
