The clamping metal assembly is to be enclosed by a base and a cover body having one end connected to the base with a swinging material to clamp the pipe member, and a fastening screw attached to the base at the other end of the cover body with a swinging material. The nut receiving part is formed to engage the tip of the nut and tighten it with a nut, the tube member is surrounded by the base and the cover body, and the clamping bracket body is formed by clamping by tightening with the fastening screw and the nut. The two bases are connected to each other such that their bases are turned against each other so that they can be rotated to each other, and the base of one of the two clamping bracket bodies pivots on the swinging portion of the fastening screw. The stopper is supported, and the stopper which stops rotation of both clamping bracket bodies at an appropriate angle is arrange | positioned, And an engaging cutout for engaging the engaging piece of the stopper at the base of the other clamp bracket body of the two clamping bracket bodies, and swinging the stopper to engage the engaging piece. It is formed so as to be able to rotate by clamping the two clamping bracket bodies by proper engagement by releasing, and releasing the engagement, thereby intersecting the orthogonal type clamping pipes at right angles and at an appropriate angle. It is designed to be used as a material type to clamp in a state.

[Problems that the invention tries to solve]

In such a clamp metal structure assembly for connecting pipes, both orthogonal types for clamping pipes at right angles and a material type for clamping in a state intersected at an appropriate angle can be used. Therefore, it is not necessary to prepare clamping tools of both types. Therefore, the ease of use is good and excellent. In this case, when the pipe member is clamped with the stopper engaging portion and the engaging cutout portion to have an orthogonal function, the engaging state is released. You must stop.

By the way, in the case of the clamp metal structure assembly for connecting pipes, as a means for preventing the release thereof, the stopper is brought into contact with the circumferential surface of the pipe in a state where the pipe is clamped to both clamp brackets, thereby making it impossible to swing. In order to prevent the release of the stopper from touching the pipe and to stop the swing of the stopper itself, the stopper of the stopper is exactly in contact with the pipe. It is necessary to ensure that the accuracy of the stopper shape is extremely good, and in addition, the adhesion accuracy of the stopper must also be good.

Further, as the above-described clamping metal assembly for pipe connection, the locking piece is protruded at the tip of the stopper, and the locking piece is coupled to the engaging notch cut out on the base of the other clamping bracket body. When strong clamping force is applied to the clamping bracket body or pipe member while the clamping bracket body is prevented from rotating at an appropriate angle, deformation or damage is likely to occur on the engaging piece, its surroundings, or the engaging hook portion, and both clamps There was a disadvantage in that it was difficult to maintain a state in which rotation of the gold bodies was prevented at a predetermined angle.

Therefore, in view of the above-described problems, the present invention uses a orthogonal type for clamping pipes at right angles and a material type for clamping in a state intersected at an appropriate angle, while forming a frame for the construction site using pipes. Can secure a secure and firm locking state in each state, even in the case of orthogonal clamping or clamping in an intersecting state at an appropriate angle.

[Action]

The clamping bracket for pipe connection according to the present invention is to be surrounded by a base and a cover body having one end pivoted about the base to clamp the pipe, and clamped by clamping with a fastening screw and a nut. Since the main body is formed and the two clamping bracket bodies are connected to each other so that the bases face each other so as to be rotated to each other, the pipe members clamped by the clamping bracket bodies can be clamped at right angles. Even when clamping in a state intersected at an appropriate angle, it is in a state that can be coped with in any case.

In the base of one of the two clamp bracket bodies, a stopper is pivotally supported on the swinging shaft portion of the fastening screw to prevent rotation of the two clamp bracket bodies at an appropriate angle. The stopper is formed in a substantially frame shape with a suitably selected metal material, and the side of the stopper comes into contact with the side surface of the base of the other clamping bracket body by the swinging operation so that the rotation between the two clamping bracket bodies can be prevented at an appropriate angle. Since it is comprised, rotation of both clamping bracket bodies is prevented by the contact of the clamping body main body of the stopper one side to the base side surface, and the angle of both clamping bracket bodies is set in that state. And if this angle is set to orthogonal state, for example, what is called orthogonal clamp is possible.

Then, one stop means for engaging the stopper is provided in the stopper, and another stop means for engaging the stopper that engages with one of the stop means of engaging the stopper is provided in the base of one clamp bracket body. When attaching one clamping bracket main body by tightening screw and nut, the mounting shaft is formed to be movable slightly in the direction in which the tightening screw is tensioned by the nut, and it is engaged in the position where the swinging shaft is moved in the tensioned state. Engagement with one side of the release jersey The release mechanism with the other side of the release jersey is engaged with the other side of the stopper side, so that the engagement state of the clamping bracket body on the other side of the stopper side is maintained. The disengagement stop is engaged and the stop disengagement function is activated, and the stopper Even if the accuracy is not improved, the engagement release is performed, and the engagement state is firmly prevented, and the fastening screw and the nut are not released to release the engagement with the one release means and the other release release means. As long as the clamping brackets are rotated between each other, they are certainly prevented from coming off.

Furthermore, a stopper which is pivotally supported by the swinging material is arranged at the base of one clamping bracket body of the two clamping bracket bodies, and the stopper is pivotally supported by the swinging material. On the side of the base of the clamping bracket body on the side, an engaging body to be engaged with the stopper is provided, and they are engaged so as to prevent rotation of both clamping bracket bodies at an appropriate angle. As long as the stopper is engaged and the stopper stops functioning, the stopper does not engage in particularly good precision, and the stopper is engaged and the engagement state is maintained firmly, and the stopper and the stopper are not released. Rotation between the clamp bracket bodies is securely prevented and there is no peeling off.

Further, by placing the stopper on the base of the other clamping bracket body, the stopper is doubled, and the rotation between the clamping bracket bodies is prevented more reliably and there is no peeling off. Moreover, even if a strong external force is applied to the clamping bracket body or the pipe member, the stopper is hardly deformed, and the state where the rotation of both clamping bracket bodies is prevented from a proper angle is securely maintained.

And in all these aspects, when a stopper is released, it functions as what is called a clamp tool of a material type.

Since the engaging body which prevents rotation of the main body is protruded and the stopper is formed in a roughly frame shape so that the engaging body can be held, the stopper is held by the stopping body by clamping the stopper to the engaging body. The bracket body is prevented from rotating relative to another suitable clamp bracket body or the like.

In one embodiment of the concrete structure, when the clamping attachment of the tightening screw is clamped by the fastening screw and the nut, the fastening screw is formed to be slightly movable in the direction in which the fastening screw is pulled by the nut. In the position where the attachment shaft moved to the tensioned state, one of the disengagement stoppers installed on the stopper and the other disengagement stoppers installed on the engaging body were formed to engage in an unseparable manner. The release stop function is engaged by the release means on one side and the release means on the other side. The stop release function works, and the stop state is secured by the stopper and the engagement body. And loosening the fastening screw and the nut by means of one of the Il is not be reliably prevented or the like being rotated about a different number of pages other suitable clamp bracket body of the clamp bracket body does not release the engagement of the end.

In addition, as a form of the concrete structure, one of the stop means for engaging the stopper provided on the stopper is used as the engaging protrusion, and the other stop means for engaging the stopper provided in the engaging body is used as the engaging hole. The engaging projection is securely engaged with the engaging hole, and the engaging state of the stopper to the engaging body is securely maintained. That is, unless the nut is loosened, the stopper does not fall out of the engagement body.

The stopper 11 which is supported and stops rotation of both clamping bracket bodies 1a and 1b at an appropriate angle is arrange | positioned. Here, the angle is, for example, an angle at which the two clamping bracket bodies 1a and 1b are orthogonal. Then, the base 2b of the other clamping tool body 1b is engaged with the engaging piece 1b of the stopper 11 to rotate the clamping tool bodies 1a and 1b with each other at an appropriate angle. An engaging cutout portion 12 is provided as an engaging portion for blocking.

The engaging piece 11b of the stopper 11 is provided with an engaging projection 11a serving as an engaging release blocking means for preventing the engaging of the engaging piece 11b and the engaging cutout 12. In the engaging cutout portion 12 provided on the base 2b of the other clamping tool body 1b, the engaging recess as the other means for engaging the release releasing member engaging with the engaging projection 11a. In addition, as shown in the drawing, the notch 12 is formed on the side piece 2d, which is formed to secure the strength of the member side edge constituting the base 2b of the clamping tool body 1b, to secure the strength thereof. An engagement releasing stopper portion 12a is provided in which the engaging projection 11a is caught by the side piece 2c while the stopper 11 is engaged.

On the other hand, the swinging attachment shaft 4a of the fastening screw 4 is attached to the base 2a of one clamping tool body 1a, but at that time, the member side edge constituting the base 2a is secured. The shafts are inserted between the side pieces 2c and 2d which are raised on both sides for the purpose, and the inserted state of the shafts is the long holes 2e and 2c provided at both ends of the swing attachment shaft 4a by the side pieces 2c and 2d. The shaft is inserted into the shaft so that the swing attachment shaft 4a is moved in the longitudinal direction of the long holes 2e and 2e.

The longitudinal directions of the long holes 2e and 2e are formed by one of the screw 4 and the nut 5, as shown in Fig. 5B or 5C. When the clamping bracket body 1a is fastened, the fastening screw is tightened by the nut 5. Here, as shown in FIG. 5A instead of the long holes 2e and 2e, the shaft insertion hole 2f is enlarged to a size such that the swing attachment shaft 4a does not fall off. The swing attachment shaft 4a may be moved in the direction in which the tightening screw 4 is tensioned by the share of the rattling.

The swing attachment shaft 4a thus formed has the same axis as the pivot support shaft which pivotally supports the stopper 11. In other words, the stopper 11 is pivotally supported on the swinging attachment shaft 4a, whereby the nut (1a) is clamped by the clamping screw 4 and the nut 5 to tighten the clamping bracket body 1a. 5) the stopper 11 is formed to be movable slightly in the direction in which the fastening screw 4 is tensioned, and the engaging projection of the stopper 11 is in a position where the swing attachment shaft 4a is moved in the tensioned state. (11a) and the engagement release blocking portion 12a are formed to engage, whereby the engagement of the stopper 11 is prevented, for example, as described above, the two clamping bracket bodies 1a, 1b. ) Is fixed in an orthogonal state and is designed to function as a so-called orthogonal clamping bracket.

In this case, the pivot support shaft of the stopper 11 and the swing attachment shaft 4a may be integrally formed by fixing them separately. Moreover, as a shape of the engagement protrusion part 11a of the said stopper 11, the shape which planted and provided the processus | protrusion as shown in FIG. 6 (A), or cut | disconnected as shown in FIG. 6 (B) The shape may be a curved shape or a bent shape as shown in FIGS. 6C and 6D. However, the shape is not limited to this shape and may be any shape that protrudes.

Then, by loosening the fastening screw 4 and releasing the rotation stop between the clamping bracket bodies 1a and 1b by the stopper 11, it functions as a so-called clamping member of angular material type.

On the other hand, as shown in Figs. 7 to 10, as another embodiment, the stopper 21 is formed in a substantially frame shape with a metal material, and the side surface of the stopper is formed on the base side of the other clamp metal fitting body 1b. By making contact with each other by surface contact, the clamping bracket bodies 1a and 11 are rotated at an appropriate angle, and the clamping bracket bodies 1a and 1b are formed to intersect at right angles to connect the pipe members P. In the same manner as in the above embodiment, when fastening one of the clamping tool bodies 1a by the fastening screw 4 and the nut 5, the stopper (1) is tightened by the nut 5 in the direction in which the fastening screw is tensioned. 21) One side of the engagement release stopper is brought into surface contact with a part of the base 2b of the other clamp metal fitting body 1b while the pivot support shaft of 21) is slightly moved, and is engaged by the other release release stopper. It is formed so as to perform alignment releasing.

Specifically, as shown in FIGS. 7 and 8, the fastening screw is formed by bending the metal plate into a U-shape to form a stopper 21, and forming both release ends thereof in the same manner as in the above embodiment. It is formed so that it may pivotally support by the swinging attachment shaft 4a of (4). And the engaging projection 21a is planted and installed in the middle inside of the c-shape of this stopper 21, On the other hand, in the base 2b of the other clamp metal fitting body 11, the side shape is substantially L-shaped. The engaging body 22 is fixed to the base 2b with the back surface of the granular body 2b, and the said engaging protrusion 21a is attached to the horizontal piece 22c of the substantially L-shaped engaging body 22. As shown in FIG. The engagement hole 22a which engages in the is provided. This engaging hole 22a may be a through-hole as shown, or it may be a blocking hole, although not shown in figure, and it may have any shape as long as the said engagement protrusion 21a is a recessed part which can be engaged.

In this structure, firstly, the stopper 21 is swung and the side of the base 2b of the other clamp metal fitting 1b, in fact, the granulation of the engaging body 22 fixed to the side surface. When the side surface of the stopper 21 is surface-contacted to 22b, and it clamps by the clamping screw 4 and the nut 5, the pipe material P is clamped by the one clamp metal body 1a, The stopper 21 moves in the direction in which the fastening screw 4 is tensioned, and the engaging projection 21a and the engaging hole 22a of the stopper 21 are engaged at that position, whereby the stopper 21 is engaged. This disengagement is prevented.

In this case, at the position where the stopper 21 has moved in the direction in which the fastening screw 4 is tensioned, the engaging projection 21a of the horizontal piece 22c of the engaging body 22 and the stopper 22 is provided.

In addition, as shown in FIG. 10, as another form of the engaging body 22, the granular piece 26 of some height is formed in the front-end | tip of the horizontal piece 22c of the engaging body 22, and this granule ( The inner surface of the side 26 is formed on the inclined surface so that the width becomes narrower as the horizontal piece 22c approaches the gap piece 22b, so that the stopper is not provided with the projection or engagement hole in the horizontal piece 22c. Both sides of (21) fall between the mouth piece 221) and the mouth piece 26 to simultaneously perform the locking stop between the engagement release stop and both clamping bracket bodies 1a and 1b, in which case, The engaging body 22 itself having the stopper 21 and the mouth piece 26 constitutes one of the disengagement blocking means and the other of the disengagement blocking means. In the case of these embodiments, the side surface of the stopper 21 may be directly in surface contact with the base 2b of the clamping tool body 1b without providing the granules 22b in the engaging body 22. In addition, since the inner side surfaces of the two c-shaped release pieces constituting the stopper 21 are positioned so as to sandwich the side surfaces of the engaging body 22, the inner side surfaces of the stopper 21 may be brought into surface contact with each other. . In addition, the engagement releasing jersey one means and the engagement releasing jersey other means are not limited to the structure of the above-described embodiment, but are engaged with the stopper 21 slightly moved in the direction in which the fastening screw 4 is tensioned. Any structure can be used as long as the structure can be released. In this case, the stopper 11 is the same.

In addition, as shown in FIG. 11, the side surface of the stopper 21 is directly brought into surface contact with the side surface of the base 2b of the other clamping tool body 1b, and the engagement hole as the other means for preventing the engagement release ( The same effect is obtained even when 22a) is formed on the back surface of one clamp bracket body 1a.

On the other hand, although not shown in the drawing, the other side of the clamping bracket body 1b on which the stoppers 11 and 21 are not provided arranges the stopper on the base 2b, and the engaging portion to which the stopper engages is placed. The clamping bracket body 1a is installed on the base 2a, and in this stopper, one of the clamping release stops, such as a locking projection for preventing the locking release, is set in the same manner as in the above embodiment. The base of the main body is also set with the other means for engaging the releasing stop, such as the engaging recess for engaging with the one with the releasing stop, and pivoting the stopper in the same way as the stoppers 11 and 21 of the clamping fixture main body. In the position where the supporting side is moved in the tensioned state, it may be formed so that one means of engagement release and the other means of engagement release are fully engaged. The.

And in all these forms, when the stoppers 11 and 21 are released, it functions as a so-called clamp clamp of a material type.

Next, as shown in FIGS. 12 to 16, the material clamp is fastened to the bases 2 and 2a of the clamp bracket bodies 1 and 1a. A stopper 11 pivotally supported on the swinging attachment shaft 4a of the screw 4 by pivoting is provided, and the other stopper 11 is hooked or peeled off by the swinging motion of the appropriate clamping bracket body 1b. The engaging body 22 which engages with material and prevents rotation of the clamping bracket bodies 1 and 1a is protruded and comprised, and is comprised. In addition, the stopper 1l is formed in a substantially frame shape, and is formed to hold the engaging body 22.

Then, the swinging shaft 4a of the tightening screw is tightened by the nut 5 when the clamping tool bodies 1 and 1a are tightened by the tightening screw 4 and the nut 5. ) Is slightly movable in the direction in which it is tensioned.

Then, at the position where the swing attachment shaft 4a is moved in the tensioned state, one of the engagement release blocking means provided on the stopper 11 and the other engagement release blocking means provided on the engagement body 22 are separated. It is formed to engage with impossibility.

That is, the stopper 11 is provided with an engaging projection 11a as one of the means for preventing engagement to stop the engagement with the engagement body 22, and the base of another suitable clamping bracket body lb The engagement body 22 provided in 2b) is provided with the engagement hole 22a as another engagement release | blocking means which engages with the said engagement protrusion part 11a.

The stopper 11 is formed to be movable slightly in the direction in which the screw 4 is tensioned, and is engaged with the engaging portion 11a of the stopper 11 at the position where the swing attachment shaft 4a is moved in the tensioned state. The engaging holes 22a of the fitting body 22 are formed to engage, whereby the disengagement of the stopper 11 to the engaging body 22 is prevented, for example, as described above. 1) and other suitable clamping bracket bodies lb are fixed in an orthogonal state and formed to function as a so-called orthogonal clamping bracket.

As the shape of the engaging projection 11a of the stopper 11, for example, one projected from the opposite side by a punch or a press, or a projection or a plant is formed or cut, or bent. Any shape may be used as long as it is a shape which protrudes without being limited to these shapes.

The stopper 11 is formed by bending a metal plate into a U-shape, and is formed to pivotally support both of the release ends by the swinging attachment shaft 4a of the fastening screw 4. However, the engaging projection 11a protrudes from the middle inside of the c-shape of the stopper 11.

On the other hand, the engaging body 22 is fixed to the base 2b of the other suitable clamping tool body 1b, and the latching part 22c of this engaging 22 is engaged with the said engaging protrusion 11a. Dowel holes 22a are formed.

The engagement hole 22a may be a through hole or a blocking hole, and may be any shape as long as the engagement protrusion 11a is a recessed portion that can be engaged.

In this structure, firstly, the stopper 11 is rocked, and the side surface of the stopper 11 is brought into surface contact with the side surface of the base 2b of the other suitable clamping tool body 1b. When the pipe member P is clamped by the clamping bracket body 1a by tightening with the nut 5, the stopper 11 moves in the direction in which the tightening screw 4 is tensioned, and the stopper 11 at that position. The engagement projection 11a and the engagement hole 22a engage with each other, whereby the release of the stopper 11 is prevented.

In this case, at the position where the stopper 11 has moved in the direction in which the fastening screw 4 is tensioned, the engaging pieces 22c of the engaging body 22 and the engaging protrusion 11a of the stopper 22 are provided. Since the surface is brought into surface contact, the rotational stopping strength of the clamping bracket body la relative to the other suitable clamping bracket body 1b as a whole becomes much better, for example, a proper angle between the pipe members P, in fact, an orthogonal cross state. The strength of is secured sufficiently.

On the other hand, as another form of the engaging body 22, as shown in FIG. 17, the same protrusion 25 as the engaging protrusion part 21a of the said Example is hooked on the horizontal piece 22c of the engaging body 22. As shown in FIG. It may be set as the other means for misalignment prevention, and although not shown in this case, an engagement hole is provided in the stopper 11 side. And as shown in FIG. 18, as another form of the engagement body 22, the slightly high granular particle 26 is formed in the front end of the horizontal piece 22c of the engagement body 22, and the By forming the inner surface on the inclined surface so that the width becomes narrower as it approaches the horizontal piece 22c, both sides of the stopper 11 are different from the side of the base 2b without the protrusion or the engaging hole. It intervenes between the side of the base 2b of the bracket main body 1b and engages to release and stop the rotation of the clamping bracket main bodies 1a and 1b at the same time. The engaging body 22 itself has a means for disengaging jersey and the other means for disengaging jersey.

In addition, since the inner side surfaces of the two c-shaped release pieces constituting the stopper 11 are positioned so as to sandwich the side surfaces of the engaging body 22, the inner side surfaces of the stopper 11 may be in surface contact with each other. Incidentally, the engagement releasing jersey one means and the engagement releasing jersey other means are not limited to the structure of the above-described embodiment, but are walked with the stopper 11 slightly moved in the direction in which the fastening screw 4 is tensioned. Any structure can be used as long as it can be prevented from releasing, and the same applies to the stopper 11.

By the way, the other directly connected clamping bracket 1b may have the same configuration as the clamping brackets 1 and 1a, such as those shown in Figs. 12 and 13 and clamping the ground pipe P. And a rotating bracket 31 which is connected to the clamping bodies 1 and 1a with a rotating material through the pivoting portion 7 as shown in FIG. 14 and the pivot 32 is pivoted through the rotating bracket 31. A substantially U-shaped steel attachment portion 30 and a tightening screw 33 screwed to the steel attachment portion 30, the tip of the tightening screw 33 and the steel attachment portion 30. For example, the clamp bracket main body 1b which may be pressed and fixed to a part of steel frame or the like may be used as an example.

Incidentally, in the case where the fitting body 22 is protruded to another suitable clamping bracket body 1b as shown in FIG. 14, the fitting body 22 is welded to the rotary bracket 31 as shown in the example. Alternatively, it may be directly welded to the fitting body 22 on the steel frame attachment part 30, and the cost of down can be achieved without requiring the rotary bracket 31, or the fitting body 22 ) Is integrally connected to the rotary bracket 31 to reduce the number of parts, and the fitting body 22 may not be welded, and furthermore, the degradation in strength of the speech portion may be eliminated. Alternatively, the substrate on which the engaging body 22 protrudes is retrofitted between the clamping bracket body 1a and the other suitable clamping bracket body 1b, and the substrate is fixed to the other suitable clamping bracket body 1b. By other suitable clamps But it may be used to obtain the main body (1b).

[Effects of the Invention]

The clamping bracket for connecting pipes according to claim 1 is to be surrounded by a base and a cover body having one end pivoted about the base to clamp the pipe, and clamped by tightening with a fastening screw and a nut. A main body is formed, and the two clamping bracket bodies are connected to each other so that the bases face each other so that they can be turned to each other, and one of the two clamping bracket bodies is provided with a fastening screw swing. A stopper pivotally supported on the shaft portion is pivotally supported, and the stopper is formed in a roughly frame shape with a suitable metal material, and the side surface of the stopper comes into contact with the side surface of the base of the other clamping bracket body by the swinging operation. Since it is configured to prevent rotation between the main bodies at an appropriate angle, It is possible to prevent the rotation of the other side of the clamping bracket body of the bracket between both clamp body by simply abutting the side of a stopper on the base side, it is set in the angle of the two clamps between bracket body as it is. In other words, if this angle is set to, for example, the orthogonal state, the so-called orthogonal clamp becomes possible. Further, the pipe member clamped by the clamping bracket bodies can be in a state that can be coped even when clamping at an orthogonal angle even when clamping at right angles, for example. By the stop of rotation by this stopper or its stopping, the clamping tool of both types of cross type, for example, orthogonal type and angular material type can be used.

Particularly, the stopper is formed in a substantially frame shape with a suitable metal material, and the rocker is configured so that the side of the stopper comes into contact with the side surface of the base of the other clamping bracket body so as to prevent rotation between the two clamping bracket bodies at an appropriate angle. The stopper itself is extremely superior in strength, for example, even if a strong external force is applied to the clamping bracket body or pipe member while preventing the clamping bracket body from rotating at an appropriate angle. The base of the clamping bracket body is hardly deformed and damaged, and it is possible to reliably maintain the state in which rotation between the clamping bracket bodies is prevented at a predetermined angle.

The clamp bracket for joining pipes according to claim 2 is to be surrounded by a base and a cover body having one end connected to the base with a swinging material to clamp the pipe, and clamped by tightening with a fastening screw and a nut. A main body is formed, and the two clamping bracket bodies are connected to each other such that the bases face each other so that they can be rotated to each other, and a clamping screw is mounted on one of the two clamping bracket bodies. A stopper pivotally supported by a swinging material is placed on a portion of the copper-clad portion of the stopper, which is formed in a roughly frame shape with a suitably selected metal material. It is constructed so as to prevent rotation between the two clamping bracket bodies at an appropriate angle, and engages the stopper. One means for releasing stop is provided, and the other means for releasing brace engaged with one of the means for releasing stop is installed on the base of one clamping bracket body, and the swinging shaft of the fastening screw is tightened with the fastening screw and nut. When fastening one clamping bracket main body by means of the nut, the fastening screw is formed to be slightly movable in the tensioning direction by the nut, and is engaged with one of the means for preventing engagement by the swinging attachment shaft in the tensioned state. Since the other means of engagement release engagement is engaged and the contact state of the clamping bracket body on the other side of the stopper side to the base side is maintained, rotation of both clamping bracket bodies can be prevented. In this state, the angle between the two clamping bracket bodies is set. In other words, if the angle is set in an orthogonal state, for example, so-called orthogonal clamps are enabled. Further, the pipe member clamped by the clamping brackets can be in a state that can be coped even when clamping at an orthogonal angle even when clamping at an orthogonal angle. By the stop of rotation by this stopper or the release of the stop, the clamping brackets of both types, such as orthogonal and angular materials, can be used.

Particularly, the stopper is formed in a substantially frame shape with a suitable metal material, and the rocker is configured so that the side of the stopper comes into contact with the side surface of the base of the other clamping bracket body so as to prevent rotation between the two clamping bracket bodies at an appropriate angle. When the stopper material is extremely superior in strength, for example, when a strong external force is applied to the clamping bracket body or pipe member while preventing the clamping bracket body from rotating at an appropriate angle, The base of the clamping bracket body is hardly deformed and damaged, and it is possible to reliably maintain the state in which rotation between the clamping bracket bodies is prevented at a predetermined angle.

In particular, the stopper is provided with one means for disengaging stops, and the other side of the clamping bracket body is provided with another means for disengaging stops for engaging with one of the means for disengaging stops; When attaching one clamping bracket main body by tightening screw and nut, the fixing shaft is formed to be movable slightly in the direction of tension of the tightening screw by the nut. Since the other means is engaged with the jersey means and the other means are engaged with each other, the contact state with the other side of the base of the clamping bracket on the side of the stopper is maintained. And disengagement jersey can engage the other means, and the other clamp base To touch the sides meet the side of the stopper to be so that the rotation of both clamp fitting between the body can be prevented at an appropriate angle. In addition, by tightening the fastening screw by engaging the other means of engagement release brace and the other means of engagement release jersey, the stopper moves in the direction of strengthening the engagement between the two clamping bodies so that the clamping bracket bodies can be rotated more reliably. It is possible to prevent it, and the engagement state will not come off unless the tightening screw and nut are loosened. Further, the accuracy of the shape of the stopper, the attachment structure, and the like is not required, and the overall processing cost can be suppressed.

The clamping bracket for connecting pipes according to claim 3 is to be clamped by clamping the pipe by clamping the pipe with one end of the base and a cover body having a rocking material connected to the base. A main body is formed, and the two clamping bracket bodies are connected to each other so that the bases face each other so that they can be turned to each other, and one of the two clamping bracket bodies is provided with a fastening screw swing. On the side part, a stopper pivotally supported by a swinging material is arranged, and the stopper is formed into a roughly frame shape with a properly selected metal material, and a fastening body for engaging the stopper is provided on the side of the base of the other clamping bracket body. They are engaged so that both clamp brackets can rotate at proper angles. Hayeoteumeuro, both clamping bracket and can prevent the mutual rotation of the body, it is set in the angle of the two clamps between bracket body as it is. In other words, if the angle is set to, for example, the orthogonal state, the so-called orthogonal clamp is enabled. Further, the pipe member clamped by the clamping brackets can be in a state that can be coped even when clamping at an orthogonal angle even when clamping at an orthogonal angle. By stopping the rotation by this stopper or releasing of the stopper, it is possible to have both clamps of cross type, for example, orthogonal type and angular material type.

Particularly, the stopper is formed in a substantially frame shape with a suitable metal material, and the rocker is configured so that the side of the stopper comes into contact with the side surface of the base of the other clamping bracket body so as to prevent rotation between the two clamping bracket bodies at an appropriate angle. The stopper itself is extremely superior in strength, for example, even if a strong external force is applied to the clamping bracket body or pipe member while preventing the clamping bracket body from rotating at an appropriate angle. The base of the clamping bracket body is hardly deformed and damaged, and it is possible to reliably maintain the state in which rotation between the clamping bracket bodies is prevented at a predetermined angle.

In the clamping bracket for pipe connection of the fourth aspect, the stopper is also placed on the base of the other clamping bracket body, so that the stopper is doubled, and the fastening screw and the nut of both clamping bracket bodies are loosened to engage with the engagement release blocking means. Unlocking Release Clamp Unless the engagement with the other means is released, the rotation between the clamping bracket bodies is more securely prevented and there is no deviation. Therefore, the locking clamp can be performed reliably, thereby providing a more stable pipe clamp. Can provide brackets.

The invention of the rotation stop device in the material clamp bracket described in claim 5 is to be surrounded by a body and a cover body which is connected to one end of the base with a swinging material so as to clamp the pipe, and fastened with a fastening screw and a nut. In the clamp-type bracket formed by attaching the clamping bracket body to be clamped, and connecting the base back portion of the clamping bracket body to other suitable clamping bracket bodies to be a rotating material. A stopper pivotally supported on the swinging shaft is pivotally supported, and on another suitable clamping bracket body, the stopper is engaged by the swinging operation or engaged with the peeling material to prevent the clamping body from rotating. Protrude and install the stopper in the shape of frame so that it can hold the fitting body. Since the property, even when the tubes are for example, perpendicular to the clamping by the clamp the clamping bracket main body, even when the clamp in a state intersecting at a suitable angle, it is possible to adapt to operate on it in any case.

Thus, a stopper is pivotally supported on the base of the clamping bracket body by pivoting on the swinging attachment shaft of the fastening screw, and on another suitable clamping bracket body, the stopper is engaged with the stripping material by the swinging motion. And the engaging body supporting the rotation of the clamping bracket main body is protruded, and the stopper is formed in a roughly framed shape so that the engaging body can be held. Therefore, the stopper and the engaging body are engaged with each other. Rotation of the clamping bracket body relative to the clamping bracket body is prevented, and in that state, the angle of the clamping bracket body relative to the other suitable clamping bracket body is set. In other words, if the angle is set to, for example, an orthogonal state, the so-called orthogonal clamp is enabled.

Therefore, it is possible to serve as a clamping tool of an intersecting type, for example, an angular type between an orthogonal type and an angular material type, by the stop of rotation by the stopper or the release of the stop. In addition, the machining cost of the entire clamping tool can be suppressed without requiring high precision of the shape of the stopper, the attachment structure, the shape of the engagement body, the attachment structure, and the like.

In addition, the rotation stop device of claim 6 is formed so as to be movable slightly in the direction in which the tightening screw is tensioned by the nut when the clamping bracket main body is tightened by the tightening screw and nut. In the moved position in the tensioned state, the stopper stopper means provided on the stopper and the stopper stop stop means installed on the stopper are formed to engage in an unremovable manner. Is moving in the direction of strengthening the engagement between the clamping bracket body and the other suitable clamping bracket body, so that the engagement means of the stopper and the engagement means are engaged with the stopper and the other means. Unless the clamping screw and nut are loosened, the clamping bracket body relative to the other clamp bracket body Rotation is certainly prevented from falling out.

Particularly, as a form of the concrete structure, the rotation stop device according to claim 7 uses one of the engagement release stoppers provided on the stopper as a engagement protrusion, and engages the other engagement release stops provided on the engagement body. Since the engagement projections and the engagement holes are securely engaged, the engagement state between the stopper and the engagement body is not released unless the fastening screws and nuts are loosened.

And in all of these forms, when a stopper is released, it functions as a so-called clamp clamp of a material type.

Thus, for example, even when the scaffolding of the construction site is framed by the pipe, both the orthogonal type clamping the pipes at right angles and the material type clamping at a proper angle, even when clamping at right angles. Even when clamping in a state where they cross at an appropriate angle, the jamming is not released in each state, and the pipe members are reliably assembled and connected to each other at an appropriate angle, which is very excellent in strength, and further suppresses the cost up. There are several excellent effects.
