And fix.

  ADVANTAGE OF THE INVENTION According to this invention, shape fixtures, such as H-section steel and C-section steel, can be fixed easily and firmly, and the fixture for improving work efficiency and safety | security is realizable.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the fixture 10. FIG. 2 is a front view of the fixture 10 viewed from the back side of FIG. FIG. 3 is a side view of the fixture 10 viewed from the right side of FIG.

  The fixture 10 is a metal fitting used to connect and fix C-shaped steel and H-shaped steel (not shown). The fixture 10 includes a plate-like main body portion 12 having a notch 16 and a flange portion 14 extending perpendicularly to the main body portion 12 from an end portion of the main body portion 12. A plate-like first bulging portion 18 extends from the main body portion 12 toward the notch 16 along the main body portion 12, and between the first bulging portion 18 and the main body portion 12, One groove 20 is formed. Furthermore, a plate-like second bulging portion 22 bulging from the main body portion 12 is provided in a direction perpendicular to both the main body portion 12 and the flange portion 14 so as to face the flange portion 14. A second groove 24 is formed between the bulging portion 18 and the second bulging portion 22. Further, the main body 12 is provided with a screw hole 26 for fixing the shape steel. The screw hole 26 is at the same height as the first and second grooves 20 and 24 in a state where the flange portion 14 is on the upper side.

  The first and second bulging portions 18 and 22 are respectively formed with first and second upper end surfaces 36 and 38 for holding the shape steel at the end portion on the flange portion 14 side. The first and second upper end surfaces 36 and 38 are both parallel to the flange portion 14 and perpendicular to the rotation axis of the bolt 28. The first bulging portion 18 is chamfered at the corner on the first groove 20 side including the first upper end surface 36. Similarly, the second bulging portion 22 is also chamfered at the corner on the second groove 24 side including the second upper end surface 38.

  The fixture 10 includes a bolt 28 screwed to the flange portion 14 and a first nut 30 screwed to the bolt 28 to fix the bolt 28 to the flange portion 14. The bolt 28 has a pad 32 for pressing the shape steel at the tip.

  A disc-shaped pressing surface 34 for pressing the shape steel is provided at the tip of the pad 32 (see FIG. 2). The pad 32 is connected to the bolt 28 so as to be displaceable. That is, the pad 32 can swing around the axis of the bolt 28. Further, a second nut 40 for screwing the bolt 28 is fixed to the flange portion 14 on the tip end side of the bolt 28. The 2nd nut 40 is welded to the flange part 14, and the bolt 28 can fix a shape steel more firmly compared with the case where only the flange part 14 is screwed together. Further, the second upper end surface 38 of the second bulging portion 22 is on the extension line of the bolt 28, and the pressing surface 34 of the pad 32 and the second upper end surface 38 face each other. That is, when the bolt 28 moves in the direction perpendicular to the flange portion 14 (arrow A), the distance between the pressing surface 34 and the second upper end surface 38 is adjusted according to the thickness of the shape steel to be pressed. .

  Since the main body 12, the flange 14, the first and second bulges 18 and 22 have a single plate-like structure, the fixture 10 is formed by cutting and bending one plate. Is done.

  FIG. 4 is a diagram schematically showing the arrangement of C-shaped steel and H-shaped steel fixed in directions orthogonal to each other. 5 and 6 are side views showing the fixture 10 that fixes the C-shaped steel and the H-shaped steel so as to be orthogonal to each other.

  As shown in FIG. 4, when the C-shaped steel 50 and the H-shaped steel 60 are fixed so as to face in the directions perpendicular to each other, the fixing tool 10 can be attached to the upper flange of the C-shaped steel 50 by the following two methods. The two structural steels can be connected and fixed so that the portion 52 and the flange 62 of the H-shaped steel 60 are in contact with each other.

  The first fixing method will be described with reference to FIG. The fixing device 10 is formed so that the upper flange portion 52 and the lip 54 of the C-shaped steel 50 pass through the notch 16, the end of the flange of the H-shaped steel 60 is in contact with the body portion 12, and the C-shaped steel 50. It arrange | positions so that the lip | rip 54 may be engaged with the 1st groove | channel 20 (henceforth 1st arrangement | positioning). In the fixture 10, the first bulging portion 18 and the second bulging portion 22 press the upper flange portion 52 of the C-shaped steel 50 from the lower side, and the pad 32 presses the flange 62 of the H-shaped steel 60 from the upper side. As a result, the C-shaped steel 50 and the H-shaped steel 60 are connected and fixed. In this case, the fixture 10 is disposed such that the main body 12 and the second bulge 22 are both inclined with respect to the lip 54.

  Since the pad 32 has the pressing surface 34, the contact area with the flange 62 of the H-section steel 60 is larger than when only the front end surface (not shown) of the bolt is in contact. The H-shaped steel 60 can be firmly fixed. Further, since the pad 32 is connected to the bolt 28 so as to be displaceable, the pad 32 can be efficiently pressed while corresponding to some unevenness on the surface of the flange 62.

  In the first arrangement, when the lip 54 is engaged with the second groove 24 in order to fix the C-shaped steel 50 and the H-shaped steel 60 arranged in the same manner as in FIG. Compared to the arrangement (refer to FIG. 6), the fixture 10 can more strongly connect and fix the C-shaped steel 50 and the H-shaped steel 60. In the first arrangement, unlike the second arrangement, not only the second upper end surface 38 of the second bulging portion 22 but also the first upper end surface 36 of the first bulging portion 18 is a C-shaped steel 50. This is because the C-shaped steel 50 is held while pressing the upper flange portion 52. However, in the first arrangement, since the screw hole 26 is separated from the lip 54, the C-shaped steel 50 cannot be fixed more strongly using screws.

  A second fixing method (second arrangement) will be described with reference to FIG. In the second arrangement, in the fixture 10, only the second bulging portion 22 presses the upper flange portion 52 of the C-shaped steel 50 from the lower side, and the pad 32 presses the flange 62 of the H-shaped steel 60 from the upper side. . In this case, the fixture 10 is disposed so that the main body 12 overlaps the lip 54. And since the 1st upper end surface 36 does not contact the upper flange part 52 of the C-shaped steel 50, the 1st bulging part 18 does not contribute to fixation of a shaped steel. Therefore, the fixing strength by the fixture 10 in the second arrangement is lower than in the first arrangement.

  However, in the second arrangement, since the main body portion 12 contacts the lip 54 of the C-shaped steel 50, the C-shaped steel 50 can be more firmly fixed by screws (not shown) through the screw holes 26. it can. The screw hole 26 is formed slightly below the extended surface extending from the first upper end surface 36 and the second upper end surface 38 on the same plane, and the screw reaching the lip 54 through the screw hole 26 is The fixing of the C-shaped steel 50 by the fixture 10 is assisted.

  FIG. 7 is a perspective view showing the fixture 10 in which the C-shaped steel 50 and the H-shaped steel 60 are connected in a state of being orthogonal to each other. In FIG. 7, the right fixture 10 shows a first arrangement and the left fixture 10 shows a second arrangement.

  8 and 9 are diagrams schematically showing a case where the C-shaped steel 50 and the H-shaped steel 60 are arranged in parallel.

  When the C-shaped steel 50 and the H-shaped steel 60 are fixed in a parallel state, the fixture 10 is arranged as shown below to connect and fix the shaped steel. That is, the fixture 10 is such that the upper flange portion 52 and the lip 54 of the C-shaped steel 50 and the flange 62 of the H-shaped steel 60 pass through the notch 16 and the end of the H-shaped steel 60 is the main body. It arrange | positions so that the lip | rip 54 of C-shaped steel 50 may engage with the 1st groove | channel 20 so that the part 12 may be contacted (it is hereafter called 3rd arrangement | positioning, refer FIG. 9).

  In the third arrangement, as in the first arrangement, the fixture 10 is configured such that the first bulging portion 18 and the second bulging portion 22 press the upper flange portion 52 of the C-shaped steel 50 from below, When the pad 32 presses the flange 62 of the H-shaped steel 60 from above, the C-shaped steel 50 and the H-shaped steel 60 are connected and fixed.

  In the C-shaped steel 50, the upper flange portion 52 and the lip 54 are not strictly orthogonal to each other, and there is a thick corner portion 56 in an inner region where the upper flange portion 52 and the lip 54 are in contact with each other. Therefore, the first and second bulging portions 18 and 22 are chamfered on the first and second grooves 20 and 24 sides, respectively.

  As described above, according to the present embodiment, there is no fixing work such as welding work, and there is provided a fixing tool that firmly and easily fixes the shape steel such as the C-shaped steel 50 and the H-shaped steel 60. Realized.

  The pad 32 increases the contact area of the H-shaped steel 60 with the flange 62 and enables the H-shaped steel 60 to be firmly fixed. However, sufficient fixing strength can be obtained by contact only with the front end surface of the bolt 28. If provided, it may not be provided. Further, the tip of the bolt 28 may be processed into a tapered shape in order to prevent deviation from the surface of the shaped steel.
