Therefore, the connection position of the edge mounting portion 51 with respect to the clamp mounting portion 52 can be arbitrarily adjusted within a range in which the screw portion of the fixing bolt B <b> 2 is inserted into the long hole 57.

  The size of the notch hole 58 is not limited as long as at least the head of the fixing bolt B2 can pass through, but the head of the fixing bolt B2 can be secured with a spanner or the like even when the head of the fixing bolt B2 straddles the notch hole 58. A size that can be supported so as not to rotate by being sandwiched is more preferable. When the size of the notch hole 58 cannot be increased so much, although not shown, a hole is provided on the side surface of the head of the fixing bolt B2 while being large enough to allow the head of the fixing bolt B2 to pass. Etc. may be inserted so that the head does not rotate during fastening. Moreover, although not shown in figure, it is good also as C shape seen from the side which provided the slit along the longitudinal direction of the trunk edge attaching part 51. FIG.

  In this embodiment, the variable connecting fitting 5 has the through hole 55 of the trunk edge mounting portion 51 as a long hole, but although not shown, the through hole 56 of the clamp mounting portion 52 is a long hole, and further, the connection side opening end. It is good also as a form which provided the notch hole in 52a.

  Next, an embodiment of the method of assembling the barricade P will be described in detail with reference to FIGS. FIG. 9 is an explanatory view showing an example of a method of attaching the linear connecting metal fitting 4 to the upper body edge 23 of the panel 2, and FIG. 10 is an explanatory view showing an example of an attaching method of the variable connecting metal fitting 5 to the lower body edge 24 of the panel 2. FIG. 11 shows an embodiment of the method of assembling the barricade P, and is an exploded explanatory view showing the relationship between the panel 2 to which the linear connecting fitting 4 and the variable connecting fitting 5 are attached, and the support 1. First, as shown in FIG. 9, the trunk edge attaching portion 41 of the linear fixture 4 is inserted from the left and right ends of the upper trunk edge 23 of the panel 2, and the inverted U-shaped presser fitting 6 is attached to the upper barrel. The nut N1 is screwed onto the outer edge 23 by inserting the fixing bolt B1 through the presser fitting 6, the upper trunk edge 23 and the trunk edge mounting portion 41 in the front-rear direction.

  Next, as shown in FIG. 10, the trunk edge mounting portion 51 and the clamp mounting portion 52 of the variable connecting metal fitting 5 are temporarily fixed by screwing the fixing bolt B2 onto the nut N2, and then the trunk edge mounting portion 51 and the clamp. The relative position with respect to the attachment part 52 is connected so that it can be changed. Subsequently, the trunk edge attaching portion 51 of the variable connecting metal fitting 5 is inserted into each of the left and right ends of the lower trunk edge portion 24 of the panel 2, and the U-shaped holding metal fitting 6 is externally fitted to the lower trunk edge portion 24. The fixing bolt B1 is inserted through the presser fitting 6, the lower body edge 24 and the body edge attaching part 51 in the front-rear direction, and the nut N1 is screwed.

  Next, as shown in FIG. 11, the variable coupling connected to the clamp 11 above the support body 1 and attached to the lower trunk edge 24 by attaching the clamp mounting portion 42 of the linear coupling fitting 4 attached to the upper trunk edge 23. The clamp attachment portion 52 of the metal fitting 5 is attached to the clamp 11 below the support 1. At this time, as shown in FIG. 8, the position of the clamp attachment portion 52 can be changed in the vertical direction with respect to the trunk edge attachment portion 51, so that the height of the lower trunk edge portion 24 and the clamp 11 below the support body 1. The variable connecting bracket 5 can be mounted by adjusting the positional relationship between the clamp mounting portion 52 and the trunk edge mounting portion 51 in accordance with the height of the bracket. And each fastening bolt B1 and B2 are finally tightened and each connection location is fastened. Thereby, when the heights of the upper clamps 11 of the clamps 11 of the left and right support bodies 1 are adjusted, even if the lower clamps 11 are slightly different in height, it is impossible to use the variable connecting bracket 5. Since the support body 1 and the panel 2 can be connected to each other, it is easy to attach the barricade P, and it is possible to prevent a biased connection state in which unnecessary stress is locally generated.

  Further, in this embodiment, the linear connecting fitting 4 is attached to the upper trunk edge 23, and the variable coupling fitting 5 is attached to the lower trunk edge 24. From the appearance, the height of the clamp 11 of the support 1 and the panel 2 is preferable because the height matches the upper trunk edge 23, but the variable coupling 5 may be attached to the upper trunk 23 and the linear coupling 4 may be attached to the lower trunk 24.

  Furthermore, as shown in FIG. 12, as the support 1, a general barricade support 1 having an A-shape in a side view and having two upper and lower clamps for supporting a steel pipe can also be used. In other words, the support 1 has a slightly different distance between the upper and lower clamps 11 depending on the manufacturer and product specifications. The panel 2 can be attached between the supports 1 by using the variable connecting metal 5 without preparing the connecting metal. In general, the difference in the vertical distance of the clamp 11 on the support body 1 is often within the range of the diameter of the tubular body attached to the clamp 11, so that the length of the long hole 57 provided in the lid member 53 is long. However, if the difference in the distance between the clamps 11 does not fall within the above range, the variable connecting bracket 5 may be used for both the upper and lower sides.

  In addition, for example, even when the number of the supports 1 is insufficient with respect to the prepared panel 2, the support prepared in advance on one side using the general barricade support 1 at the installation site is used. By using the body 1 and the support body 1 at the installation site on the other side, the barricade P according to the present invention can be assembled.

  FIGS. 13-14 is explanatory drawing which shows another form of the barricade based on this invention, (a) is a partial disassembled perspective view before an assembly, respectively, (b) is a perspective view after an assembly, respectively. That is, FIG. 13 shows two barricades P connected in the horizontal direction using the continuous fitting 7, and FIG. 14 shows that the panel 2 is connected to one barricade P using the same continuous fitting 7. Thus, two panels 2 are attached between three supports 1 arranged side by side in the lateral direction.

  In this embodiment, the continuous fittings 7 are formed in a substantially cylindrical shape, and the clamp attachment portions 32 are mutually inserted by inserting the both ends thereof into the clamp attachment portions 32 of the connection fitting 3 to be connected. To connect. Thereby, the fall of the barricade is prevented, the safety at the construction site is improved, and the space through which the passerby can pass is reduced, and the slip-through can be effectively suppressed. In this embodiment, the connecting bracket 7 simply connects the connecting brackets 3 to each other, so that the mounting work is easy, and the outer diameter of the connecting bracket 7 is in contact with the inner wall portion of the clamp mounting portion 32. If it can be adjusted to such an extent that it can be contacted or pressed, it is more preferable because the connecting metal fitting 7 becomes difficult to come off. Although not shown in the drawings, for example, the clamp mounting portion 32 of the connection fitting 3 attached to the trunk edge portions 23 and 24 of the panel 2 from the left and right may be attached to the clamp 11 of one support body 1.

  The present invention relates to a general barricade assembled using a tubular body such as a steel pipe and a side-view "A" -shaped support body, that is, the upper and lower clamps for mounting the tubular body. Even if the interval is slightly different, it is possible to attach a panel using a connecting bracket between the supports, so that not only when newly installing a barricade at a construction site or a construction site, it is already used at the site. A barricade using a tubular body can be suitably used as a barricade in which the tubular body is removed and the panel is replaced.
