Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, when forming scaffolding at a construction site with pipes, the pipes are securely assembled and connected at appropriate angles, or the pipes are appropriately attached to a steel frame. The present invention relates to a rotation stopping device in a universal clamp metal fitting that can be securely assembled and connected at an angle.

[0002]

2. Description of the Related Art Conventionally, as a flexible clamp metal fitting of this type, which connects pipe members at an appropriate angle, Japanese Patent Laid-Open Publication No. 6-1 is known.
There is a clamp metal fitting assembly for connecting pipe materials provided in Japanese Patent No. 08637.

This clamp metal fitting assembly is surrounded by a base body and a lid body having one end swingably connected to the base body for clamping the pipe material, and the base body is provided at the other end of the lid body. Clamp fitting that engages the tip of the fastening screw that is swingably attached to the nut and forms a nut receiving portion to tighten with the nut, surrounds the pipe material with the base body and the lid, and clamps by tightening the fastening screw and the nut The main body is formed and two of these clamp metal fitting bodies are connected to each other with their bases back to back so that they can rotate freely. A stopper is provided on the base body so as to be swingably supported by the swing mounting portion of the fastening screw to prevent rotation of both clamp metal fitting bodies at an appropriate angle, and a locking piece is projected on this stopper. Let me set An engaging notch that engages with the locking piece of the stopper is formed on the base body of the other clamp metal body of the two clamp metal bodies, and the locking piece is engaged by swinging the stopper. By engaging with the notch, rotation of both clamp metal fittings is blocked at an appropriate angle,
It is formed so that it can be rotated by releasing its engagement,
As a result, the orthogonal type in which the pipes are clamped at right angles to each other and the free type in which the pipes are clamped in an intersecting state at an appropriate angle are also used.

[0004]

In such a pipe member connecting clamp fitting assembly, there are an orthogonal type which clamps the pipe members at right angles and a free type which clamps them at a proper angle. Since it does not need to prepare both types of clamp metal fittings, it is easy to use and excellent.In that case, for example, in order to have the function of the orthogonal type, the stopper piece and the engagement notch of the stopper If the tubing is clamped in the engaged condition, it must be prevented from disengaging. However, in the case of this pipe material connecting clamp fitting assembly, as a means for preventing the release, the stopper piece of the stopper contacts the peripheral surface of the pipe material while the pipe material is clamped on both clamp fitting bodies. The structure is designed so that the stopper cannot be rocked and the engagement is prevented from being disengaged. Therefore, in order to make the structure in which the stopper locking piece comes into contact with the pipe material to prevent the stopper itself from swinging, the pipe material is clamped. In this state, it is necessary to ensure that the stopper locking piece is in contact with the pipe material accurately, and the accuracy of the stopper shape must be extremely good. Must also be good. As a result, there is a problem that the overall processing cost increases.

In view of the above-mentioned problems and the like, the present invention, for example, uses both an orthogonal type in which pipes are clamped at right angles and a free type in which they are clamped in a state intersecting at an appropriate angle, Even when clamping at right angles when forming scaffolds of etc. with tubing,
Even when clamped in a state of intersecting at an appropriate angle, a secure locked state can be secured in each state, easy handling, excellent strength, and cost reduction can be controlled freely. The object of the invention is to provide a rotation stopping device for a mold clamp.

That is, reference numeral 1 shown in the figure is a clamp metal fitting body, which is surrounded by a base body 2 and a lid body 3 having one end swingably connected to the base body 2 for clamping the pipe material P. At the other end of the lid body 3, there is formed a nut receiving portion 6 for engaging the tip end portion of a fastening screw 4 which is swingably attached to the base body 2 and tightening it with a nut 5.
The pipe material P is surrounded by the base body 2 and the lid body 3 and clamped by tightening with the fastening screw 4 and the nut 5.

Further, the bases 2 and 2a of the clamp metal fitting bodies 1 and 1a are provided with stoppers 11 which are pivotally supported by the rocking mounting shafts 4a of the fastening screws 4, and other suitable clamp metal fitting bodies 1b. The stopper 11 is disengageably engaged with the stopper 11 by its swinging motion, and the clamp metal fitting bodies 1, 1
An engaging member 22 is provided so as to prevent the rotation of a. Moreover, the stopper 11 is formed in a substantially frame shape,

The angle at which the clamp fitting bodies 1 and 1a are prevented from rotating with respect to the other clamp fitting body 1b is, for example, an angle at which the clamp fitting bodies 1 and 1a are orthogonal to the other clamp fitting body 1b.

The oscillating mounting shaft 4a of the fastening screw 4 is formed so as to be slightly movable in the direction in which the fastening screw 4 is pulled by the nut 5 when fastening the clamp metal fitting bodies 1, 1a with the fastening screw 4 and the nut 5. To be done. Then, at the position where the swing mounting shaft 4a has been moved to the pulled state, the engagement release blocking one means provided in the stopper 11 and the engagement release blocking other means provided in the engagement body 22 engage in a non-separable manner. Is formed.

That is, the stopper 11 is provided with an engagement protrusion 11a as one means for disengagement prevention which prevents disengagement from the engagement body 22, and another suitable base body 2b of the clamp fitting body 1b. The engaging body 22 provided in
An engagement hole 22a is provided as the other means for preventing engagement release, which engages with the engagement projection 11a.

The oscillating mounting shaft 4a of the fastening screw 4 is mounted on the base body 2a of the clamp metal fitting body 1a. At that time, the side edges of the members constituting the base body 2a are erected on both sides to secure the strength. It is mounted between the side pieces 2c and 2d,
As for the shaft mounting state, both ends of the swing mounting shaft 4a are side pieces 2c, 2
the long holes 2e, 2e provided in the
It has a structure in which the swing mounting shaft 4a is mounted so as to be movable in the longitudinal direction of e and 2e. And the long hole 2
The longitudinal direction of e and 2e is as shown in FIG. 7 (B) or FIG. 7 (C).
As shown in FIG. 5, when tightening the clamp fitting body 1a with the fastening screw 4 and the nut 5, the fastening screw 4 is pulled by the nut 5. Here, instead of the elongated holes 2e, 2e, as shown in FIG. 7 (A), the shaft mounting hole 2f is enlarged to a size in which play is generated to the extent that the swing mounting shaft 4a does not fall off. The amount of play
The swing mounting shaft 4a may be movable in the direction in which the fastening screw 4 is pulled.

The swing mounting shaft 4 thus formed
The stopper 11 also pivotally supports the stopper 11, and the fastening screw 4
The position where the stopper 11 is formed to be slightly movable in the direction in which the fastening screw 4 is pulled by the nut 5 when the clamp fitting body 1a is tightened by the nut 5 and the nut 5, and the swing mounting shaft 4a is moved in the pulled state. Is formed so that the engaging projection 11a of the stopper 11 and the engaging hole 22a of the engaging body 22 are engaged with each other.
The disengagement of 1 from the engaging body 22 is prevented, and, for example, as described above, the clamp metal fitting body 1a and the other appropriate clamp metal fitting body 1b are fixed in an orthogonal state, and function as a so-called orthogonal type clamp metal fitting. Is formed.

The shape of the engaging protrusion 11a of the stopper 11 is, for example, one punched from the opposite side by a punch, press, etc., one in which a projection is planted, one cut out or raised, or Although there is a bent shape, the shape is not limited to these shapes, and any shape may be used as long as it has a protruding shape.

Then, by loosening the fastening screw 4 and releasing the rotation prevention of the clamp metal fitting body 1a with respect to the other clamp metal fitting body 1b by the stopper 11, the so-called universal clamp metal fitting whose angle can be freely changed. It fulfills its function.

The stopper 11 is formed by bending a metal plate material in a U shape, and both open ends of the stopper 11 are pivotally supported by the swing mounting shaft 4a of the fastening screw 4. An engaging projection 11a is provided on the inside of the U-shaped intermediate portion of the stopper 11. On the other hand, the engaging body 22 is fixed to the base body 2b of the other clamp fitting body 1b, and the lateral piece 22c of the engaging body 22 is formed with the engaging hole 22a that engages with the engaging projection 11a. ing. This engagement hole 2
2a may be a through hole or a blind hole, and may have any shape as long as it is a concave portion with which the engaging projection 11a can be engaged.

In the case of this structure, first, the stopper 11 is swung to bring the side surface of the stopper 11 into surface contact with the side surface of the base body 2b of the other clamp fitting body 1b, and then the fastening screw 4 and the nut 5 are attached. When the pipe material P is clamped by the clamp metal fitting body 1a by tightening with, the stopper 11 moves in the direction in which the fastening screw 4 is pulled,
At that position, the engaging protrusion 11a of the stopper 11 and the engaging hole 2
2a are engaged with each other, which prevents the stopper 11 from being disengaged.

Further, in this case, at the position where the stopper 11 moves in the direction in which the fastening screw 4 is pulled, the lateral piece 22c of the engaging body 22 and the surface of the stopper 22 on which the engaging projection 11a is provided are in surface contact. Therefore, as a whole, the rotation inhibiting strength of the clamp metal fitting body 1a with respect to the other appropriate clamp metal fitting body 1b is remarkably excellent,
For example, an appropriate angle between the pipe members P, and in reality, the strength in the orthogonal crossing state is sufficiently secured.

On the other hand, as another mode of the engaging body 22, as shown in FIG. 8, a projection 25 similar to the engaging projection 21a of the above-mentioned embodiment is provided on the lateral piece 22c of the engaging body 22 for disengagement preventing means. Although not shown, in that case, an engaging hole is provided on the stopper 11 side.
Further, as shown in FIG. 9, as another mode of the engaging body 22, a standing piece 26 having a slight height is formed at the tip of the lateral piece 22c of the engaging body 22, and the inner surface of the standing piece 26 is , Horizontal piece 22c
By forming the inclined surface so that the width becomes narrower as it gets closer to, the both side surfaces of the stopper 11 are formed on the side surface of the base body 2b and the base body of the other clamp metal fitting body 1b without providing a protrusion or an engaging hole on the horizontal piece 22c. It is fitted between the side surface of 2b and the side surface of 2b to simultaneously prevent the disengagement and the rotation of the clamp fitting bodies 1a and 1b. In that case, the engaging body 22 itself having the stopper 11 and the standing piece 26 is engaged. The engagement release prevention one means and the engagement release prevention other means are constituted. Furthermore, since the inner side surfaces of the U-shaped release pieces forming the stopper 11 are positioned so as to sandwich the side surface of the engaging body 22, both inner side surfaces thereof may be in contact with each other to form a surface contact state. The disengagement blocking one means and the disengagement blocking other means are not limited to the structure of the above-described embodiment, and are engaged in the state where the stopper 11 is slightly moved in the direction in which the fastening screw 4 is pulled. Any structure may be used as long as it can prevent the release, and the same applies to the stopper 11.

By the way, other appropriate clamp metal fitting body 1b
May have the same structure as the clamp metal fitting bodies 1 and 1a for clamping the pipe material P as shown in FIGS. Swing fitting 31 rotatably connected via 7
And a substantially U-shaped steel frame attachment portion 30 that is swingably attached to the swing fitting 31 via a pivot 32, and a tightening screw 33 screwed to the steel frame attachment portion 30. Attached screw 3
The clamp fitting body 1b may be configured such that the tip of 3 and a part of the steel frame attachment part 30 can be pressed and fixed to a part of a steel frame or the like.

In addition, when the engaging body 22 is provided so as to protrude from the other clamp fitting body 1b as shown in FIG. 4, for example, the engaging body 22 is welded to the swing fitting 31 as shown in the figure. Or, the engaging body 2 may be attached to the steel frame mounting portion 30.
2 may be directly welded to eliminate the need for the swinging fitting 31 to reduce the cost, or
The engaging body 22 is integrally connected to the swing fitting 31 to reduce the number of parts, and the engaging body 22 does not need to be welded, and the deterioration of the strength of the connected portion can be eliminated. Alternatively, the board on which the engaging body 22 is projected is interposed between the clamp metal fitting body 1a and another appropriate clamp metal fitting body 1b, and the board is attached to another suitable clamp metal body 1b. Alternatively, the existing clamp metal fitting body 1b may be used as appropriate.

In all of these modes, if the stopper 11 is released, it functions as a so-called free-type clamp fitting.

[0031]

According to the present invention thus formed, the tube member is surrounded by the base body and the lid body whose one end is swingably connected to the base body so as to clamp the pipe material, and the fastening screw and the nut are used. A clamp type clamp metal body which is clamped by tightening is formed, and a back surface of the base body of the clamp metal body is rotatably connected to another suitable clamp metal body or the like. The base of the clamp metal fitting body is provided with a stopper pivotally supported by a rocking mounting shaft of a fastening screw, and the stopper is removably engaged with the other clamp metal fitting body by its rocking motion. In combination, an engaging body that prevents rotation of the clamp metal fitting body is provided in a protruding manner, and the stopper is formed in a substantially frame shape,
Since the engaging body is formed so that it can be held, the pipe material clamped by this clamp metal fitting body can be clamped in a state in which it intersects at an appropriate angle even when it is clamped at a right angle. Even if there is, it can be in a state that can handle both cases.

Therefore, a stopper pivotally supported by the swing mounting shaft of the fastening screw is provided on the base body of the clamp metal fitting body, and the stopper is pivotally operated on other suitable clamp metal body. Engages and disengages with
Since the engaging body that blocks the rotation of the clamp metal fitting body is provided in a protruding manner and the stopper is formed in a substantially frame shape so that the engaging body can be held, the stopper and the engaging body can be engaged with each other. The rotation of the clamp fitting body with respect to the other suitable clamp fitting body is prevented, and in that state, the angle of the clamp fitting body with respect to the other suitable clamp fitting body is set.
That is, if this angle is set to the orthogonal state, for example, a so-called orthogonal clamp is possible.

Therefore, the rotation is prevented by this stopper,
Alternatively, by releasing the blocking, it is possible to serve as a cross-type clamp metal fitting, for example, both a right-angled shape and an angled type.

Further, the swing mounting shaft of the fastening screw is formed to be slightly movable in the direction in which the fastening screw is pulled by the nut when the clamp metal fitting body is tightened by the fastening screw and the nut, and the swing mounting shaft is pulled. At the position moved to the locked state, the engagement release prevention one means provided on the stopper and the engagement release prevention other means provided on the engagement body are formed so as to be inseparable from each other. Is moving in a direction that strengthens the engagement between the clamp metal fitting body and another appropriate clamp metal fitting body, so that the engagement release preventing one means and the engagement release preventing other means engage with each other to form the stopper and the engaging body. Is surely performed, and unless the fastening screw and the nut are loosened, the rotation of the clamp metal fitting body with respect to the other clamp metal fitting bodies is reliably prevented and does not come off.

In the case of the conventional example, when clamping in the orthogonal state, the pipe material is clamped on both clamp metal fitting bodies in order to prevent the engagement state of the engaging piece of the stopper and the engagement notch from being released. In this condition, the stopper must have a very precise shape so that the stopper's locking piece will come into contact with the peripheral surface of the pipe material, and the stopper's mounting accuracy must also be good, which causes a problem of cost increase. However, in the case of the present invention, as described above, the engagement by the stopper is not released unless the fastening screw and the nut of the clamp fitting body provided with the stopper are loosened. Accuracy is not required, and it is possible to suppress an increase in overall processing cost.

In particular, as one mode of its concrete structure, one of the disengagement blocking means provided on the stopper is the engaging projection and the other disengagement blocking means provided on the engaging body is the engaging hole. The engagement between the stopper and the engagement body will not be disengaged unless the engagement projection and the engagement hole are reliably engaged and the fastening screw and the nut are loosened.

In all of these modes, if the stopper is released, it functions as a so-called free-type clamp fitting.

Therefore, for example, when the scaffolding at a construction site is framed by the pipe material while using both the orthogonal type for clamping the pipe materials at right angles and the free type for clamping the pipe materials in a state intersecting at an appropriate angle, , Whether it is clamped at a right angle or when it is clamped in a state where it intersects at an appropriate angle, the pipes are securely assembled and connected at an appropriate angle without releasing the lock in each state. However, it is also very excellent in strength and has various excellent effects such as cost reduction.
