DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection bracket of a field support for connecting a pair of field supports for supporting a pair of ceiling plates forming corners of a ceiling.

[0002]

2. Description of the Related Art Conventionally, in connecting a pair of channel-shaped field supports at the corner of a ceiling, the pair of field supports are back-to-back, fixed by a clamp, and further welded. Thus, these two fields were connected.

[0003] However, in the case of welding, it is not easy to start the work due to the preparation of a welding machine, and it is very difficult to perform the welding work facing upward in a narrow ceiling space. Is also complicated.

[0004] In general, the ridgeline at the corner of the ceiling cannot be clearly seen unless the both edge supports are accurately crossed at a predetermined angle at a predetermined position. However, the mounting positions of the edge supports are deviated by only a few millimeters. The appearance of the ceiling is unsightly.

[0005] However, it is extremely difficult to connect the long field margins with a precision of several millimeters and then to connect them with a clamp. There was a risk of damaging the appearance

[0006]

In view of such a problem,
SUMMARY OF THE INVENTION An object of the present invention is to provide a connection fitting capable of connecting a pair of edge supports so that a corner ridge of a ceiling plate can be neatly looked through while being easily constructed without using a welding machine. is there.

[0007] Further, by interposing the connecting metal fitting between the pair of field supports, it becomes difficult to bring the planes of the webs of both field supports close to each other, and there is a possibility that strength may be disadvantageous. Therefore, another object of the present invention is to provide a connection bracket for a field support that can connect both field supports in a state where the planes of the webs of the field supports are brought as close as possible to each other. .

[0008]

In order to achieve the above object, a first characteristic configuration of a connecting bracket of a field support according to the present invention comprises a pair of fields supporting a pair of ceiling plates forming corners of a ceiling. In the configuration for connecting the rims, a pair of connecting bodies each having a connecting portion for connecting to each of the rims is provided,
The pair of connecting bodies are rotatably connected around a rotation axis that intersects the center line in the width direction of each of the connecting parts and is substantially parallel to the ridge line of the corner, and the pair of connecting bodies are aligned with respect to the rotation axis direction. The two connecting portions of the pair of connecting members were overlapped at the rotation shaft portion, and a cylindrical portion protruding from one connecting member toward the other connecting member was formed on the other connecting member. By penetrating through the through-hole and bending the tip of the cylindrical portion in the radial direction about the rotation axis to form a retaining flange, these two connected bodies are rotatably connected around the rotation axis. It is in.

[0009]

[0010]

[0011]

According to a second characteristic configuration of the present invention, in addition to the first characteristic configuration, the field support has at least a flange and a web arranged substantially orthogonal to the rotating shaft, and the connection members Forming a web contact portion by protruding a peripheral portion of a retaining flange of the other connected member from a back surface of the one connected member, the portion having a web contact portion capable of contacting the web. The rear portions of the two connecting members are brought into contact with each other even in a peripheral portion separated from the vicinity of the retaining flange.

According to a third aspect of the present invention, in addition to the first or second aspect, the field support is a channel, and the connecting portion is bent toward the groove of the channel. The provision of a bent piece engageable with the flange of the channel.

[0014]

According to the first characteristic configuration, for example, FIGS.
As shown in FIG.
8 and 18 are connected rotatably about a rotation axis P that intersects the center lines C and C in the width direction and is substantially parallel to the ridge line 5a at the corners. Then, the center lines C1 and C2 of the ridges 1 and 2 are aligned with the center line C of each connecting portion.
Matches.

Therefore, first, the ceiling surface B1,
After obtaining the position of B2, the center lines C1 and C2 of the virtual field support are drawn in parallel at a position separated by a certain distance from the positions of the ceiling surfaces B1 and B2, and the center lines C1 and C1 of the field support are drawn.
The position of the virtual intersection Q of C2 is obtained.

Then, the attitude of the field support 1 is adjusted so that the center line C1 of the horizontal field support 1 passes through a predetermined position, and a predetermined distance L1 from the virtual intersection Q with respect to the field support 1 is set. , L
Mark position 2.

Thereafter, the field edge receiver 1 is connected with the portion of the connecting portion of one connecting body 12 located at the same fixed distances L1 and L2 from the rotation axis P as before, aligned with the position of the mark. Then, the position of the central axis P can be substantially matched with the position of the virtual intersection Q. Therefore, other wildlife 2
If the position of the upper end of the other frame 2 is determined, the center line C2 of the other frame 2 is also connected to the imaginary intersection Q Can be passed, and these can be easily connected while accurately maintaining the connection position of the both field borders.

[0018]

Further, since both connecting portions of the pair of connecting members are overlapped at the rotation shaft portion, as shown in FIG.
The intersection of the two margins has not been removed. Therefore, the position of the intersection Q with respect to the longitudinal direction of one of the frame receivers 1 can be written on the one of the frame receivers 1. Even after the connection, the position of the intersection Q can be reconfirmed. It is possible. In addition, since the connecting part is concentrated around the rotation axis, a field clip can be attached immediately near the intersection of both field supports 1 and 2, and the position of the ceiling surface can be accurately aligned with the field support Becomes possible.

By the way, when the pair of connecting members are turned upside down with respect to the rotation axis direction and the connecting portions are overlapped with each other, when connecting the field edge support having the web and the flange, the webs should be connected to each other as much as possible. It is desirable to make them close to each other. However, when the two connecting members are connected using bolts or the like as in the second characteristic configuration, the screwed portion of the bolt and the head of the bolt protrude at a considerable height. This is inconvenient because the receiving webs are separated.

Therefore, by projecting the cylindrical portion from one connecting member toward the other connecting member, it is possible to eliminate a projecting portion in at least one connecting portion. Also,
The retaining flange formed by bending the tip of the cylindrical portion has a high retaining effect for a small projection height, and
By making the diameter of the tubular portion considerably large, it can withstand a large shear stress. Therefore, the connection strength of the two connecting members can be maintained sufficiently high while the planes of the webs of the both edge frames are brought close to each other as much as possible.

According to the second characteristic configuration, the web contact portion is formed by projecting the peripheral portion of the retaining flange of the other connecting member from the back surface of the one connecting member. It is possible to suppress that the rim catcher connected to the connecting body of the above comes up by coming into contact with the retaining flange, thereby making the connection unstable. In addition, since the back surfaces of the two connecting members are brought into contact with each other even in a peripheral portion remote from the vicinity of the retaining flange, stress for bending the cylindrical portion is less likely to act, and the connection strength of the two connecting members is reduced. Is improved.

[0023]

As described above, according to the first characteristic configuration of the connection fitting of the ridge support according to the present invention, the corner ridge of the ceiling plate can be cleaned while being easily constructed without using a welding machine. It has become possible to connect a pair of field margins so that they can be seen through. In addition, although the planes of the webs of the two frames can be brought close to each other, the connection strength between the connected bodies can be improved.

[0024]

Further, according to the second characteristic configuration, it is possible to further improve the connection strength between the two connected bodies. Further, as shown in the third characteristic configuration, by forming the connecting portion with a bent piece that can be engaged with the flange of the channel, it is easy to finely adjust the mounting position of the connecting body with respect to the field edge receiver, and the ceiling corner portion is provided. It has become easier to accurately look through.

[0026]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a side view showing a foundation structure of a ceiling at a corner portion of a ceiling using a connection fitting 10 according to the present invention. A pair of ridges 1 and 3 are hung on a suspension bolt 4d suspended from a ceiling slab (not shown) via a hanger 4a, a retainer 4b, and a clip 4c so that the longitudinal direction thereof is oriented in the horizontal direction. Have been. The slanted frame support 2 is bridged between the end of the horizontal frame support 1 and the intermediate portion of the horizontal frame support 3, and the upper end thereof is pressed by the holding metal fitting 4 b, and the lower end thereof is connected to the connecting metal fitting 1.
0 is connected to one end of the horizontal edge support 1.

The field clip 6 is mounted on the clip mounting portion of the connection fitting 10, and the inclined field support 2 and the horizontal field support 3, and the field edge 7 is fitted to the field clip 6, and the plaster is further added. A ceiling board 5 composed of a board and a decorative board is attached. The ceiling plates 5 respectively supported by the horizontal ridge 1 and the inclined ridge 2 are joined to each other at the corners of the ceiling to form ridges 5a. Connection fitting 10 of the present invention
In a state where the ridge line 5a is viewed straight in the direction perpendicular to the plane of the drawing, the lower horizontal edge support 1 and the inclined field edge 2 are accurately aligned so that the pair of ceiling plates 5 abut each other. It is intended to connect in a proper positional relationship.

As shown in FIGS. 3 and 1, the connecting fitting 10 according to the present invention includes a first connecting body 12 for connecting to an end of the horizontal edge support 1, and an end of the inclined field edge 2. The second connecting member 14 for connecting to the portion is connected to the second connecting member 14 by a fastening bolt 19 so as to be rotatable around the rotation axis P. Each of the connecting bodies 12 and 14 can be formed by press-forming a galvanized steel sheet or the like, and the same applies to the following examples.

Each of these connecting parts 18 is connected to each of the above-mentioned field receivers 1,
A web contact portion 16 that contacts the second web w and four bent pieces 15 are provided. The bent pieces 15 are composed of tongue pieces that rise up orthogonally from the web contact portion 16, respectively, and are entangled at an intermediate portion of the bent pieces 15 to facilitate bending of the distal end. A portion 15a is provided. Then, as shown in FIG. 7, these are bent toward the inside of the field support 2, so that the bent pieces 15 are engaged with the flange f of the field support 2, and the respective field support 1, 2 are connected to each other. The two connecting members 12 and 14 are connected. Also, 4
Two of the bent pieces 15 arranged diagonally on the bent pieces 15 are formed with fixing holes 15b through which the tap screws 9 pass.

Each of the connecting members 14 and 15 has a plate-like portion 13 extending substantially in the same plane as the web contact portion 16 toward the rotation axis P. A through-hole 14a is formed in the rotation axis P portion of the plate-shaped portion 13 of the second connector 14, and a female screw portion 12a is formed in the plate-shaped portion of the first connector 12. The two plate-shaped portions 13 are overlapped with each other, and a fastening bolt 19 penetrating the through hole 12a is screwed into the female screw portion 12a to fasten the two.

The front edge clip 6 is attached to the plate-like portion 13 between the connecting portion 18 and the rotation axis P in each of the first and second connecting members 12 and 14 by slightly widening the interval therebetween. A first clip attaching portion is provided. Also,
By forming the ends around the rotation axis P of the plate-like portion 13 of each of the first and second coupling bodies 12 and 14 in an arc shape with the center axis as the rotation axis P in the rotation axis P direction, Of the field edge clip 6 with respect to the clip mounting portion.

On the back surface of the first connecting member 12, an angle defining portion for abutting the side circle of the second connecting member 14 to define the angle between the pair of connecting members 12, 14 at 90 degrees. Projection 12c is projected. Since the vicinity of the rotation axis P in the second connector 14 is formed in a flat plate shape, the second connector 14 itself is connected to the first connector 1 as shown in FIG.
2 can be inverted. Therefore, by keeping the side circle of the second connector 14 against the first connector 12 while keeping the bent pieces 15 in the same direction between the two connectors 12, 14, the both are maintained at 90 degrees. Alternatively, the two connecting members 12, 1 can be held with the bent piece 15 facing in the opposite direction.
4 can also be kept at 90 degrees by the contact of the corner defining projections 12c.

A scale 12b for displaying an angle is engraved on an arc-shaped portion of the first connecting member 12 near the rotation axis P, and an angle indicating portion 14 formed on the second connecting member 14 is formed.
By pointing the scale 12b with b, the angle formed between the two connecting bodies 12, 14 can be grasped.

The bent pieces 15 at each connecting portion 18
Between them, there is provided a distance display notch 17a indicating that the distance from the rotation axis P is constant. The notch 17a for distance display indicates that the notch 17a is separated from the rotation axis P by the distance L1, but the distance from the rotation axis P to the end 17b of the connection body at the time of manufacturing each of the connection bodies 12 and 14. L2
Can be used as a distance display unit that turns the end 17b of the connected body into a notch 17a for distance marking by managing the manufacturing accuracy so that is substantially constant.

Next, a procedure for mounting the horizontal bracket 1 while aligning it with the connecting bracket 10 using FIGS.
This will be described with reference to FIG. First, the outline B of the ceiling plate 5
1 and B2, and imaginary center lines C1 and C2 of the horizontal edge frame 1 and the sloping frame edge 2 are drawn so as to be parallel to the straight lines B1 and B2 at a fixed distance, respectively. Of the virtual intersection Q is obtained. Horizontal frame 1
A fixed distance L from the intersection Q on the flange f
A mark S1 is provided at a position separated by one by a smitting or the like.

Next, the end of the horizontal edge support 1 is fitted between the bent pieces 15 of the first connecting body 12 and
When the notch 17a for distance display matches the mark S1, the position of the rotation axis P and the virtual intersection Q substantially coincide.
Then, each of the four bent pieces 15 is bent inside the horizontal edge support 1 and engaged with the flange f, thereby fixing the first connecting body 12 to the horizontal edge support 1. Note that, in order to make the position of the rotation axis P coincide with the virtual intersection Q, even if the mark S2 is attached to the flange f at a distance equal to the distance L2 from the rotation axis P to the end portion 17b of the connector, the same applies. It is possible to get the effect.

A notch is formed at the upper end of the slanted ridge 2 and the upper end of the slanted ridge 2 is fitted into a predetermined position of the upper horizontal ridge 3. Therefore, by connecting the lower end portion of the inclined field edge support 2 to the bent piece 15 of the second connector 14, both field edge supports 1 and 2 can be connected at an accurate predetermined position, and The angle between the center lines C1 and C2 of the rims 1 and 2 is accurate. In addition, since the mounting portion of the edge clip 6 is provided near the rotation axis P, the outer diameter line of the ceiling plate 5 can be more accurately aligned with the edge supports 1 and 2. Then, if the ceiling plate 5 is attached to the both edge supports 1 and 2 via the front edge clip 6 and the edge 7, the ridge line 5 a at the corner where the pair of ceiling plates 5 and 5 intersect can be clearly seen. Will be done.

If the connection strength of the horizontal edge support 1 by the bent piece 15 is insufficient, the tap screw 9 is passed through the fixing hole 15b and the screw is screwed while the hole is locked in the flange f. By combining, the first connector 12 may be prevented from being shifted with respect to the longitudinal direction of the horizontal edge support 1. Further, by further compressing the bent piece 15 with pliers or the like in a bent state, the connection strength of the first connection body 12 in the longitudinal direction of the horizontal edge support 1 is improved.

As shown in FIG. 4, when the connection fitting 10 is used at the inner corner of the ceiling, at least one edge clip 6 can be provided in the vicinity of the rotation axis P. Can be arranged in parallel with the field margin receiver 2 even near the corner of the wall 5.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 shows an underlayer structure of a ceiling substantially similar to that of the previous embodiment, in which ends of a pair of edge supports 1 and 2 are connected to each other via a connection fitting 30, and each of the edge supports 1 to 3 is connected.
, The ceiling plate 5 is supported via a ridge clip 6 and a ridge 7. However, the first embodiment is characterized in that the slanted ridge 2 is curved in an arc shape and that the horizontal ridge 1 and the slanted ridge 2 are back-to-back with their respective openings facing opposite. And different.

As shown in FIG. 6 and FIG.
The first and second connectors 32 and 34 are rotatable about a rotation axis P that is substantially parallel to the ridgeline 5a at the corner. Most of the connecting bodies 32 and 34 in the present embodiment are composed of the connecting portion 18 configured substantially similarly to the first embodiment. The difference from the previous embodiment is that both connecting bodies 32 and 34 are connected in the rotation axis P direction. This is a point that both connecting portions 18 and 18 are overlapped with each other at the rotation axis P while turning over. Then, the head of the fastening pin 33a is placed in the recess provided in the center of the first connector 32, the shaft of the fastening pin 33a is passed through to the recess 34a, and the washer 33b is passed through the recess provided in the second connector 34. At the same time, the leading end 33c of the fastening pin 33a is crushed by a press to prevent the two from coming off.
It is connected rotatably around. In addition, each bent piece 15
A notch 37a for indicating the position of the rotation axis P is provided in the flange between the two.

In order to connect the horizontal edge support 1 and the curved inclined edge support 2 using the connection fitting 30 according to the present embodiment,
As in the first embodiment, as shown in FIG. 8, a virtual intersection Q between the center lines C1 and C2 of each field margin is obtained. Then, a mark S3 is formed at the position of the intersection Q on the flange f by smearing.
The bent piece 15 is bent in a state where the web w of the horizontal edge support 1 is in contact with the web contact portion 16 of the first connector 32, and the distance display notch 37a is made to coincide with the mark S3. The rotation axis P coincides with the virtual intersection Q, and the same effect as in the first embodiment can be obtained. According to the present embodiment, the edge clip 6
In addition, since the ridge 7 is attached, the ceiling plate 5 precisely follows the curvature of the sloping ridge 2 particularly at the lower end portion of the sloping ridge 2, so that the ridge line 5a can be more easily seen through. It should be noted that the connecting body 3 at a certain distance L3 from the rotation axis
It is also possible to match the rotation axis P with the intersection Q by matching the end 37b of the second with the mark S4 attached to the position separated from the virtual intersection Q by this distance L3. Same as the example.

Next, a third embodiment will be described with reference to FIG. In both of the above embodiments, the connecting portion 18 to the end of each of the edge supports 1 and 2 is constituted by the four bent pieces 15 and the web contact portion 16. On the other side of the connecting body 12, a locking hook 2 that engages with the flange f of the field edge support 1 is provided.
By providing two 0s and 20s, the connecting portion may be configured. Then, as shown in FIG.
0 may be engaged with one of the flanges f of the ridge holder 1 and then the bent piece 15 may be bent so as to be engaged with the other flange f.

Next, a fourth embodiment will be described with reference to FIG. To form the connecting portion 18, the connecting body 12
A pair of rising pieces 22a, 22a
The connecting portion 18 may be configured by providing an engaging portion 22b that engages with an end portion of the flange f by raising a notch and making a cut in the middle portion to raise the inside. According to the present configuration, the field edge support 1 can be fitted to the first connecting body 12 in the longitudinal direction thereof, but by providing the slope receiving slope 22c on the upper side of the rising piece 22a. It is also possible to engage the rim receiver 1 from above the connecting body 12.

Next, a fifth embodiment will be described with reference to FIGS. In the above-described first embodiment, the clip attaching portions are provided on both the first and second connecting bodies 12 and 14. However, while the second connecting body 54 is configured substantially similarly to the first embodiment, The bent piece 15 of the connecting body 52 is provided closer to the rotation axis P than the second connecting body 54, and further, a flat plate-shaped edge clip 60 that functions similarly to the edge clip 6 with respect to the fastening bolt 19 is provided. You may penetrate. In the connection fitting 50 of the present embodiment, the vicinity of the rotation axis P of the second connection body 54 is formed in a flat plate shape, and the plate-shaped edge clip 60 can be attached to the vicinity of the rotation axis P. The vicinity position corresponds to the second clip attaching portion. With this configuration, the ridge 7 is attached to the ridge clip 6 and the flat ridge clip 60, respectively, and the ridge line 5a at the corner is formed.
The ceiling plate 5 can be supported at a position closer to the ceiling plate 5.

Next, a fifth embodiment will be described with reference to FIGS. This embodiment is substantially the same as the second embodiment, but differs in the structure of the web contact portion 16 and the connecting portion between the pair of connecting members 62 and 64.

First, a cylindrical portion 63a protruding from the first connecting member 62 toward the second connecting member 64 is penetrated through a through hole formed in the second connecting member 64. Then, by bending the tip of the cylindrical portion 63a in the radial direction about the rotation axis P to form the retaining flange 63b,
These two connecting members 62 and 64 are connected so as to be rotatable around the rotation axis P. In this embodiment, the rotating shaft P is connected to the connecting portion 1 in each of the connecting bodies 62 and 64 similarly to the above embodiments.
The position of the cylindrical portion 63a and the through hole passing therethrough is set so as to be located at a position intersecting the center line C in the width direction 8 of FIG.

Also, the web contact portion 16 is formed by projecting the peripheral portion 66 of the retaining flange 63b of the second connecting member 64 from the back surface of the first connecting member 62 as an annular rib. . In the case where the diameter of the retaining flange 63b is relatively small with respect to the width of the web w, the annular rib 66 is protruded to form the web contact portion 16 in this manner, so that it is orthogonal to the web w plane of the field edge support 1. Can be prevented, and the connection by the bent pieces 15 of the field edge support 1 becomes more reliable and strong. Moreover, by forming the annular rib 66, the second connecting body 64 is reinforced and hardly deformed.

Further, the rear portions of the two connecting members 62, 64 are separated from the peripheral portions 69a, 6
9b is also in close contact with each other,
Unlike the case of the second embodiment, the bending force on the cylindrical portion 63b is reduced, and there is an effect on the strength that no load is applied to the cylindrical portion 63b. The cylindrical portion 63a, the retaining flange 63b, and the annular rib 66
Can be formed using a press machine or the like.

In order to align the rotation axis P with the virtual center Q using the connection fitting 60 according to the present embodiment, the position where the rotation axis P protrudes on the flange 15c between the bent pieces 15, 15 is determined. A projection 67a for alignment is used. In other words, the positioning projection 67a is made to coincide with the mark S3 which is marked with a smi-hit at the position of the virtual center Q in the flange f of the field margin receiver 1. As described above, the web contact portion 16
If the projections 67a for positioning are provided on the portion 15c that rises perpendicularly to the shaft, the rotation axis P can be positioned from below, so that it is very easy to perform the work in the ceiling work performed upward. There is an advantage. In addition,
In the present embodiment, the fixing hole 15b for penetrating the tap screw 9 is also passed through the position of the rotation axis P so that the fixing hole 15
The position can be adjusted also by b. In this embodiment, a line 67b for positioning is also provided at the position of the rotation axis P on the retaining flange 63b.
In contrast to the mark S5 written on the web w of Noenkei 1
By aligning the alignment lines 67b, the alignment of the connection fitting 60 can be performed.

As in the second embodiment, the ends 67b of the connectors 62 and 64 located at a fixed distance L3 from the rotation axis P and a mark S4 attached to a position separated from the virtual intersection Q by this distance L3. However, if the alignment is performed using the line 67a at the longitudinally intermediate portion of each of the connecting bodies 62 and 64, the positional deviation of the connecting fitting 60 in both the longitudinal direction of the field edge receiver 1 can be visually checked. There is an advantage that it is easy.

Next, sixth and seventh embodiments which are modifications of the fifth embodiment will be described with reference to FIGS. In the fifth embodiment, by forming the annular rib 66,
Although the web contact portion 16 is formed, as in the sixth embodiment shown in FIG. 15, the diameters of the tubular portion 63a and the retaining flange 63b are increased, and the web contact portion 16 is formed by the retaining flange 63b. You may make it. However, when the diameter of the cylindrical portion 63a is increased, the thickness of each of the connecting members 62 and 64 may be increased and the strength may be reduced. Therefore, the fifth embodiment is more excellent in that point.

Further, in the fifth embodiment, when each galvanized steel sheet is processed to form each connecting body, the annular rib 66 is made to protrude. However, as in the seventh embodiment shown in FIG. With respect to the flat web contact portion 16 of the second connector 64, a portion near the retaining flange 63b and a scattered peripheral portion 69c away from the vicinity of the retaining flange are connected to the first connector. You may make it project to 62 side. The scattered peripheral portion 69c abuts on the opposing portion 69a to reduce the force for bending the cylindrical portion 63b as in the fifth embodiment. In addition, only the portion corresponding to the scattered peripheral portion 69c of the second connecting body 64 is a bent piece 1
The web contact portion 16 may be formed in a scattered point shape by protruding toward the fifth side.

In each of the above-described embodiments, when connecting the ridges 1 and 2 to the connecting portion 18, the web w of the ridges is brought into contact with the web contact portion 16 and a bent piece is attached to the flange f. Although 15 is engaged, it is also possible to connect the flange f to the connecting portion 18 toward the web contact portion 16 side. However, the connection strength is as follows:
5 is better. When a connecting portion other than a bent piece is used, not only a channel but also a light angle steel or each pipe can be used as a field support.
