DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the fixing bracket 10 includes a clamp portion 11 and a plate material fixing portion 12. The plate material fixing portion 12 is disposed on the front surface (left side in FIG. 1) of the clamp portion 11 and is connected to the clamp portion 11 so as to be relatively rotatable.
The clamp part 11 includes a fixed piece 13 and a movable piece 14. The fixed piece 13 and the movable piece 14 are formed in a three-dimensional shape by press-molding an alloy plate. Both pieces 13 and 14 are metal fittings formed in a curved shape, and substantially semicircular arcuate surfaces 16a and 16b are formed on the inner surfaces, respectively. Both pieces 13 and 14 are connected so as to be relatively expandable about a shaft portion 15 formed on the base side.
As shown in FIGS. 1 and 2, a bolt 18 is rotatably connected to the tip of the fixed piece 13 via a shaft 19. A nut 17 is screwed to the bolt 18. A locking portion 20 is formed at the tip of the movable piece 14, and a concave groove 21 is formed in the locking portion 20 as shown in FIGS. 1, 3, and 4. The bolt 18 can be accommodated in the concave groove 21 in a state in which the tips of both the pieces 13 and 14 are close to each other, that is, in a state where the inner circumference is connected in a substantially circular shape by the circular arc surfaces 16a and 16b.
[0008]
A through hole 22 is formed at the center of the reference surface 13 a formed on the front surface of the fixed piece 13. A shaft portion 24 of a substantially square rotating plate 23 constituting a part of the plate material fixing portion 12 is inserted into the through hole 22. The rotating plate 23 is supported so as to be able to rotate 360 ° clockwise and counterclockwise with respect to the fixed piece 13 around the shaft portion 24. A restricting portion 24 a bulging outward is formed at the tip of the shaft portion 24 formed in a cylindrical shape, and the restricting portion 24 a engages with the peripheral edge of the through hole 22, thereby rotating the rotating plate. 23 is prevented from coming out of the fixed piece 13. The rotating plate 23 is loosely fitted into the through hole 22 by the shaft portion 24. Therefore, the rotary plate 23 can be rotated 360 ° with respect to the fixed piece 13 and can be slightly advanced and retracted in the front-rear direction (left-right direction in FIG. 1).
On the front surface of the rotating plate 23, a metal fitting 25 formed by bending one metal bar is welded. As shown in FIGS. 1 and 2, the holding metal fitting 25 is fixed by welding with a left and right extending portion 25 a extending in the left and right direction near the lower portion of the front surface of the rotating plate 23. The clamp 25 extends from the left and right ends of the left and right extending portions 25a at a substantially right angle to the front surface of the rotating plate 23, and the clamping portion 25c extends upward from the tip of the fixed portion 25a. . The gap formed between the clamping part 25c and the rotating plate 23 is approximately the same width as the thickness of the plate B to be fixed. The plate material B is placed on the left and right extending portions 25a and the fixed portion 25b, and is held upright by the front surface of the rotating plate 23 and the clamping portion 25c.
[0009]
As shown in FIGS. 1 to 5, a pair of engaging convex portions 26 a and 26 b as second engaging portions constituting a restricting means are provided on the back surface 23 a (the surface facing the reference surface 13 a) of the rotating plate 23. Are integrally formed. The engaging convex portions 26 a and 26 b are disposed at opposing positions with the shaft portion 24 interposed therebetween. On the reference surface 13a of the fixed piece 13, engagement holes 27a, 27b as first engagement portions constituting a restricting means at equal intervals on the rotation locus of the engagement projections 26a, 26b of the rotation plate 23, 27c and 27d are formed at four positions at equal intervals (90 ° intervals). That is, as shown in FIGS. 3 and 4, the engaging convex portions 26 a and 26 b are engaged with the two engaging holes 27 a, 27 b, 27 c, and 27 d located at diagonal positions.
[0010]
FIG. 1 shows a state in which the engaging projections 26 a and 26 b of the rotating plate 23 are engaged with the engaging holes 27 a and 27 c of the fixed piece 13. In this state, the rotating plate 23 is in contact with the reference surface 13 a of the fixed piece 13. While the back surface 23a is in contact, the engaging convex portion 26a of the rotating plate 23 is engaged with the engaging hole 27a of the fixed piece 13, and the engaging convex portion 26b is engaged with the engaging hole 27c. In a state where the engaging projections 26a and 26b of the rotating plate 23 are engaged with the engaging holes 27a and 27c of the fixed piece 13, the rotation of the rotating plate 23 is restricted. In the fixed position of the rotating plate 23 shown in the figure, the tip of the clamping part 25c of the clamping metal 25 is held upward, that is, facing the direction orthogonal to the direction in which the pipe P extends.
On the other hand, FIG. 2 shows a state where the engagement holes 27a to 27d of the fixed piece 13 and the engagement convex portions 26 of the rotating plate 23 are disengaged. In this state, the reference surface 13a of the fixed piece 13 is disengaged. The back surface 23a of the rotating plate 23 is separated. When the engagement between the engaging projections 26a and 26b of the rotating plate 23 and the engaging holes 27a and 27c of the fixed piece 13 is released, the rotating plate 23 is held in a state of being rotatable with respect to the fixed piece 13. The
[0011]
In addition to being able to be fixed at the position shown in FIGS. 1 and 3 (a), the rotating plate 23 can be fixed at the position shown in FIGS. 3 (b), 4 (a) and 4 (b). Yes. That is, in the state of FIG. 3B, the rotation plate 23 is rotated 180 ° from the state of FIG. 3A, and the engagement protrusions 26 b are formed in the engagement holes 27 a of the fixed piece 13. The rotation of the rotating plate 23 is restricted by engaging the engaging convex portion 26a with 27c. Therefore, in the fixed position of the rotary plate 23 shown in the figure, the tip of the clamping portion 25c of the holding metal fitting 25 is held facing downward to Cartesian and the extending direction of the pipe P.
In the state of FIG. 4A, the rotating plate 23 is rotated 90 ° clockwise from the state of FIG. 3A, and the engaging convex portion 26a of the rotating plate 23 is inserted into the engaging hole 27b of the fixed piece 13. Further, the rotation of the rotating plate 23 is restricted by engaging the engaging convex portion 26b with the engaging hole 27d. Therefore, at the fixed position of the rotating plate 23 shown in the figure, the front end of the clamping portion 25c of the clamping bracket 25 is held facing the right direction parallel to the direction in which the pipe P extends.
Further, in the state of FIG. 4B, the rotating plate 23 is rotated 90 ° counterclockwise from the state of FIG. 3A, and the engaging convex portion of the rotating plate 23 is engaged with the engaging hole 27 b of the fixed piece 13. 26b also engages the engaging projection 26a with the engaging hole 27d to restrict the rotation of the rotating plate 23. Therefore, at the fixed position of the rotating plate 23 shown in the figure, the tip of the clamping part 25c of the clamping metal fitting 25 is held facing the left direction parallel to the direction in which the pipe P extends.
[0012]
Next, the operation when the plate material B is fixed will be described.
First, after assembling a plurality of pipes P as a frame in a predetermined state, as shown in FIG. 5, the predetermined position of the lower pipe P is sandwiched between the fixed piece 13 and the movable piece 14 of the fixing bracket 10 and fixed. The bolt 18 on the side of the piece 13 is accommodated in a concave groove 21 formed in the locking portion 20 on the side of the movable piece 14 (the state shown in FIGS. 3 and 4), and the nut P is rotated and fixed while tightening the pipe P. I will do it. Thereby, one fixing metal fitting 10 is connected to the pipe P. Next, the rotating plate 23 of the fixture 10 fixed to the lower pipe P is rotated, and the tip of the clamping portion 25c of the clamp 25 is directed upward. When rotating the rotating plate 23, the rotating plate 23 is pulled away from the fixed piece 13, and the engagement protrusions 26a, 26b and the engaging holes 27a, 27c (or 27b, 27d) of the fixed piece 13 are engaged. This is done by releasing the joint and rotating it in a predetermined direction. When the front end of the clamping part 25c of the clamping metal fitting 25 is directed upward, the rotary plate 23 is pushed into the fixed piece 13 side to engage the engagement convex parts 26a, 26b with the engagement hole engagement holes 27a, 27c. As a result, the rotation of the rotary plate 23 is restricted, and the clamping portion 25c of the clamping bracket 25 is held in a state of facing upward.
[0013]
Next, the fixing bracket 10 is temporarily fixed to the upper pipe P facing the lower pipe P with the tip of the clamping portion 25c of the clamping bracket 25 facing downward (the nut 17 is not completely tightened). Then, when the upper portion of the plate member B is sandwiched between the rotating plate 23 and the clamping portion 25c of the fixing bracket 10, the nut 17 of the fixing bracket 10 is tightened to completely fix the fixing bracket 10 to the upper pipe P. Thereby, the board | plate material B can be clamped and fixed between a pair of upper and lower fixing metal fittings 10. FIG. Then, by arranging a pair of upper and lower fixing brackets 10 at a plurality of positions in the horizontal direction of the pipe P, the plate material B can be stably fixed to the pipe P.
Further, in FIG. 5, the fixing bracket 10 is attached to the pipe P arranged horizontally. However, as shown in FIG. 6, the fixing bracket 10 is attached to the pipe P arranged vertically. You may make it wear.
In addition, the attachment procedure of the said board | plate material B is an example, and naturally the usage method of the fixing bracket 10 other than this can also be considered. For example, in the above attachment, the plate material B is sandwiched from above and below, but in order to prevent sliding movement of the plate material B in the left and right direction, the side of the plate material B is placed on the rotating plate 23 of the fixing bracket 10. It is also possible to adopt a method of use such as sandwiching between the gripping portion 25c and the sandwiching portion 25c.
[0014]
In the present embodiment, the following effects can be obtained by configuring the fixture 10 as described above.
(1) The plate member fixing portion 12 for fixing the plate member B is connected to the clamp portion 11 so as to be rotatable by 360 °. Thereby, the direction (direction of the front-end | tip of the clamping part 25c) of the board | plate material fixing | fixed part 12 in which the board | plate material B is inserted can be changed freely, and when the board | plate material B must be fixed from the left-right direction, it fixes from the up-down direction. In any of the cases where it is necessary, one type of fixing bracket 10 can be used.
As a result, in the past, it was necessary to prepare a plurality of types of fixing brackets having plate member fixing portions with different orientations. However, in this embodiment, only one type of fixing bracket 10 can be used. This eliminates the need to separate the fixing bracket 10 before the assembly operation. As a result, the preparation time before the assembly work can be shortened, and the storage location of the fixing bracket 10 can be unified, so that the storage area of the fixing bracket 10 can be reduced.
(2) Since there is no need for the operator to check each time whether the plate member fixing portion in the correct direction is attached to the fixing bracket 10 when the fixing bracket 10 is connected to the pipe P, the temporary hut It is possible to greatly improve the assembly work efficiency.
(3) Since one type of fixing bracket 10 can cope with all directions (fixing direction of the plate material B), it is not necessary to prepare a plurality of types of fixing brackets to which plate member fixing portions having different directions are mounted, and the manufacturing cost of the fixing bracket 10 Can be reduced.
(4) Engagement holes 27a to 27d are engaged with the reference surface 13a of the fixing piece 13 of the pipe fixing part 12a, and the rotation holes 23 of the plate material fixing part 12 are engaged with the engagement holes 27a to 27d as regulating means. By forming the engaging convex portions 26a and 26b to be rotated, the rotation of the plate material fixing portion 12 relative to the clamp portion 11 can be restricted without using other restricting members. Thus, after the orientation of the plate material fixing portion 12 is determined, it is possible to prevent the orientation of the plate material fixing portion 12 from being easily changed even when an external force is applied to the plate material fixing portion 12, so that when assembling a temporary hut or the like Even if the plate material B or the like collides with the plate material fixing portion 12, it is possible to prevent the plate material fixing portion 12 from rotating unexpectedly. As a result, the assembly work efficiency of a temporary hut or the like can be greatly improved.
[0015]
(5) When the rotating plate 23 is rotated, the interval between the back surface 23a of the rotating plate 23 and the reference surface 13a of the fixed piece 13 is very narrow (a slight gap), so that the engaging convex portion 26 extends from the engaging holes 27a to 27d. Even if it comes off, it comes into contact with the reference surface 13a. This prevents the rotating plate 23 from easily rotating with respect to the fixed piece 13. That is, since the rotating plate 23 and the fixed piece 13 are loosely fitted, the engaging convex portion 26 can be easily fitted into the engaging holes 27a to 27d and cannot be freely rotated to the extent that the work is hindered. It contributes to the improvement of work efficiency.
(6) The clamping metal fitting 25 is not spot-like but welded on the line by the left and right extending portions 25a, so it is strong and does not easily fall off. In addition, the left and right extending portions 25a simultaneously hold the plate material B together with the fixing portion 25b from the lower side, thereby ensuring stable holding of the plate material B.
[0016]
The present invention may be embodied in the following manner.
In the above embodiment, the rotating plate 23 constituting the plate material fixing portion 12 is connected to the clamp portion 11 so as to be freely rotatable 360 ° clockwise and counterclockwise, but the rotating direction of the rotating plate 23 is clockwise. Or it is good also as only one direction of a counterclockwise direction.

The structure may be such that a gap that is so fine that it cannot advance or retreat (it cannot be rotated if there is no gap at all) is formed. In this case, when the rotating plate 23 is rotated, the engaging protrusions 26a and 26b displaced from the engaging holes 27a, 27b, 27c, and 27d press the reference surface 13a of the fixed piece 13 so that considerable resistance is generated. However, the reference surface 13a is made of an alloy, and the rotation of the rotating plate 23 can be allowed by bending with respect to the pressing force.
Further, a regulating member may be provided on the rotating plate 23 side or the fixed piece 13 side to regulate the rotation amount of the rotating plate 23 to 90 °, 180 °, or the like.

[0017]
In the above-described embodiment, the engaging holes 27a to 27d as the restricting means and the engaging convex portions 26a and 26b face each other, and the rotating plate 23 is pushed into the fixing piece 13 side so that both are engaged and fixed. The rotation of the rotary plate 23 relative to the piece 13 is regulated.
On the other hand, a bolt is supported at the center of the reference surface 13 a of the fixed piece 13, and the rotating plate 23 is rotatably supported with respect to the fixed piece 13 around the bolt. Then, a nut is screwed onto the bolt on the front surface of the rotating plate 23. When the nut is loosened, the rotating plate 23 is held in a state of being rotatable with respect to the fixed piece 13, while when the nut is tightened, the rotation of the rotating plate 23 is restricted. That is, the restricting means may be constituted by bolts and nuts.
In the above embodiment, the clamping bracket 25 of the plate material fixing portion 12 is embodied by bending a metal rod. However, a clamping bracket is obtained by welding a metal plate bent into a “U” cross section to the rotary plate 23. May be embodied as Alternatively, a plurality of metal bars bent into an L shape may be fixed to the front surface of the rotating plate 23.
In addition, the present invention can be freely implemented in a modified form without departing from the spirit of the present invention.
