Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scaffolding clamp for connecting pipes, etc., which is attached to an intersection of pipes for assembling scaffolding at a construction site, etc.

[0002]

[Prior art]

 Conventionally, there is a clamp of this type called a universal clamp in which a pair of fasteners are assembled so as to rotate in the same direction.

[0003]

[Problems to be solved by the device]

 In the above conventional scaffolding clamp, scaffolding members such as two pipes connected by a pair of fasteners can only move on planes parallel to each other, so the position and direction are restricted and the scaffolding is assembled. There were cripples. Further, as shown in FIG. 6, when scaffolds are assembled using conventional clamps 29, 30, 31, 32, scaffolding members such as vertical pipes 33, 34 and horizontal pipes 35, 36 to be assembled with the vertical pipes 33, 34. Has a side-by-side state (a state in which the side surfaces are in contact with each other and crosses each other), so that there is an adverse effect that the work is difficult to perform, for example, when a curing sheet is stretched along the scaffolding, and also in appearance. There is a problem that the appearance is bad. Therefore, the present invention allows the scaffolding member such as a pipe to be assembled in an arbitrary posture without being restricted in the position and direction, thereby eliminating the inconvenience in assembling the scaffolding. The purpose of the present invention is to provide a scaffolding clamp capable of assembling the scaffolding member in any structure to make the scaffolding robust and good in appearance.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the scaffolding clamp of the present invention comprises a connecting fitting 1 integrally provided with an X-axis portion 2 and a Y-axis portion 3 which are orthogonal to each other, and an X-axis portion 2 of the connecting fitting 1. On the other hand, it is composed of a first fastening member 4 which is rotatably mounted in the circumferential direction thereof, and a second fastening member 5 which is also rotatably mounted in the circumferential direction of the Y-axis portion 3 of the connecting metal fitting 1. It is configured.

[0005]

[Action]

 The direction in which the first fastener 4 rotates with respect to the X-axis portion 2 and the direction in which the second fastener 5 rotates with respect to the Y-axis portion 3 are perpendicular to each other. Therefore, by adjusting the rotation angle of the first fastener 4 with respect to the X-axis portion 2 and the rotation angle of the second fastener 5 with respect to the Y-axis portion 3, the pipe attached to the first fastener 4 is adjusted. In contrast, the pipe or the like attached to the second fastening member 5 can be placed in any posture.

【Example】

 Embodiments will be described below with reference to the drawings. First, in FIGS. 1 to 3, reference numeral 1 is a connecting fitting. The connecting fitting 1 integrally includes an X-axis portion 2 and a Y-axis portion 3 which are orthogonal to each other in a T shape. Next, the reference numeral 4 is the first fastening fitting, and the reference numeral 5 is the second fastening fitting. The first fastening member 4 is attached to the tip of the X-axis portion 2 of the connecting fitting 1 so as to be rotatable in the circumferential direction of the X-axis portion 2. The second fastener 5 is symmetrical to the first fastener 4, and the two projecting pieces 6 and 7 are provided at both ends of the Y-axis portion 3 of the coupling tool 1 so as to surround the Y-axis portion 3. It is mounted so that it can rotate in any direction. Therefore, as shown in FIG. 2, the rotation direction of the first fastener 4 and the rotation direction of the second fastener 5 are perpendicular to each other. The first fastener 4 can be rotated 360 °, but the second fastener 5 can be rotated in a range of about 180 °. The first fastening member 4 and the second fastening member 5 are both substantially semi-ring-shaped inner ring portions 8 and 9, and substantially semi-ring shaped outer ring portions 10 and 11, bolts 12 and 13, and nuts 14. , 15 and. The inner ring portions 8 and 9 are attached to the connecting fitting 1, and the outer ring portions 10 and 11 are rotatably connected at one end to the inner ring portions 8 and 9. Therefore, the inner ring portions 8 and 9 and the outer ring portions 10 and 11 can be opened and closed at their tips. The bolts 12 and 13 are rotatably connected to the tip ends of the inner ring portions 8 and 9 at their base ends, and the nuts 14 and 15 can be screwed onto the bolts 12 and 13. As shown in FIG. 3, the outer ring portions 10, 11 are provided with grooves 16, 17 at their tip portions. After inserting a pipe or the like between the inner ring parts 8 and 9 and the outer ring parts 10 and 11, insert the bolts 12 and 13 attached to the inner ring parts 8 and 9 into the grooves 16 and 17 provided in the outer ring parts 10 and 11, respectively. If the nuts 14 and 15 are screwed onto the tips of the bolts 12 and 13 that extend to the outside of the ring portions 10 and 11 and the nuts 14 and 15 are tightened, the inner ring portions 8 and 9 and the outer ring portion 10, A pipe or the like is clamped and fixed by 11.

FIG. 4 shows a state in which the second fastening member 5 is rotated by about 90 ° with respect to the Y-axis portion 3 of the coupling member 1 from the state of FIG. In this state, if the pipes 18 and 19 are clamped and fixed to the first fastening member 4 and the second fastening member 5, respectively, the pipes 18 and 19 will not be in a horizontal state and will be in a same plane with each other. You can take a vertical position. Further, by appropriately setting the rotation angle of the second fastener 5 with respect to the Y-axis portion 3 and the rotation angle of the first fastener 4 with respect to the X-axis portion 2, two scaffolding members such as pipes can be obtained. Can be assembled in any posture.

FIG. 5 shows a scaffold assembled by connecting and fixing the vertical pipes 24, 25 and the horizontal pipes 26, 27 using the clamps 20, 21, 22, 23 of the present invention. . As shown in the drawing, the vertical pipes 24 and 25 and the horizontal pipes 26 and 27 can be arranged in the same plane without being placed in a horizontal position. Reference numeral 28 is a bracing pipe attached to make the scaffold rigid. The bracing pipe 28 can also be positioned in the same plane as the vertical pipes 24, 25 and the horizontal pipes 26, 27, and can be inclined. The angle can also be set arbitrarily. When the bracing pipe 28 is arranged inside the vertical pipes 24 and 25 and the horizontal pipes 26 and 27 in this manner, the strength is increased as compared with the horizontal mounting state.

[0009]

[Effect of device]

 The present invention is as described above. When assembling scaffolding members such as pipes, there is no restriction on the position and direction of the scaffolding members, so that scaffolds can be assembled freely and easily, and curing sheets and the like can be easily and easily formed. You can stretch well. Further, the position and direction of the scaffolding member, and the angle and arrangement of the stiffeners can be arbitrarily set in consideration of strength, so that the structure of the scaffolding can be made robust.
