Description

  The present invention is an improvement of a moving barricade installed at a construction site, and more specifically, a clamp that is essential for hanging a pole can be easily and securely attached without requiring post-processing on a support leg. The present invention relates to a clamp mounting structure for a barricade support leg.

  As is well known, at road construction work and construction work sites, a mobile barricade that can prevent access is temporarily installed to clearly indicate off-limits areas in order to prevent danger and prevent outsiders from entering. This measure is effective.

  Under such circumstances, the applicant of the present application has proposed and filed a patent application for a barricade that assembles and disassembles a horizontal member such as a pole into at least two support legs in the field (see Patent Document 1). ), Registered (see Patent Document 2).

  By the way, such a conventional barricade is used by hanging a pole between at least two support legs, and a clamp for sandwiching the pole is fixed to the support leg.

  Such a general-purpose clamp C is usually composed of a part for holding the pole and a jig attached to the support leg, and is connected so that the holding part can be rotated at the time of attachment. Since a fastening part that also serves as a penetrating hole is disposed through the center of the mounting jig (see FIG. 6), in order to fix the mounting jig to the beam part of the support leg, the fixing part is fixed to the beam part. It was necessary to open the hole h (see FIG. 7) and to tighten the fastener through.

However, the machining operation for opening the fastening hole h is very troublesome, and there is a complaint that the shaved piece enters the inside of the support leg which is a hollow molded body and is difficult to remove. Further, even when filling the hollow portion with a liquid for weight, there is a problem that if there is this fastening hole, it leaks from there.

  The present invention has been made in view of the above-mentioned problems in the conventional travel barricade, particularly the support leg member, and the object of the present invention is to perform post-processing on the support leg. An object of the present invention is to provide a clamp mounting structure for a barricade support leg that can easily and surely mount a clamp essential for hanging a pole, even if not required.

  Means employed by the present inventor for solving the above-described problems will be described with reference to the accompanying drawings.

In other words, the present invention is a hollow plastic frame 1 blow-molded so as to be able to stand on the leg portion 13, and the pole member P is hung between these at least two plastic frames 1. A beam portion 11 is provided to fix the clamp 2 of
The clamp 2 is configured by connecting a pole holding part 21 and a mounting jig 22 for fixing to the beam part 11 of the plastic frame 1, and the mounting jig 22 has a shank portion s. And a fastening device 22a having heads at both ends thereof ,
A vertical groove 12 is formed on the side surface of the beam portion 11 so as to be recessed inward in the vertical direction .
Applying the shank portion s of the fastening tool 22a over the entire length of the recessed portion of the vertical groove 12 as if mating with the inner wall surface of the recessed portion ,
The fastener 22a is connected so that the pole holding portion 21 can be rotated during attachment, and the fastener 22a , which also serves as the pivot shaft, passes through substantially the center of the attachment jig 22. The attachment jig 22 is fixed to the beam portion 11 by attaching both ends of the vertical groove 12 with both heads of the fastening device 22a and being fastened, and the clamp 2 is attached. Adopted technical means.

  In addition, in order to solve the above-mentioned problems, the present invention comprises a fastening tool 22a of the mounting jig 22 of the clamp 2 as a pair of bolt members and nut members in addition to the above means as necessary. A technical means is adopted in which the bolt member is fixed by screwing with the nut member in a state where the cylindrical portion or the screw portion of the bolt member is fitted to the recessed portion of the vertical groove 12.

  Furthermore, in order to solve the above-mentioned problems, the present invention employs technical means in which an injection port 14 is provided to fill the inside of the plastic frame 1 with a load in addition to the above-described means as necessary. did.

  In the mounting structure of the present invention, a beam portion is provided in a hollow plastic frame, and a vertical groove that is recessed inward is formed on a side surface of the beam portion, and the fastening device is formed in the recessed portion of the vertical groove. By attaching the shank part to the beam part and fixing the fastener, the mounting jig can be fixed to the beam part and the clamp can be attached. In addition, even if no subsequent processing is required, it is possible to easily and reliably attach a clamp essential for hanging the pole, so that it can be said that the industrial utility value is very high.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

  A clamp mounting structure for a barricade support leg according to an embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a hollow plastic frame body, and this plastic frame body 1 is blow-molded so that it can stand up at the leg portion 13, and a beam portion 11 is formed. In the present embodiment, the polymer polyethylene is used (see FIG. 1).

  Also, what is indicated by reference numeral 2 is a clamp, and this clamp 2 is constituted by connecting a pole clamping part 21 and an attachment jig 22 for fixing to the beam part 11 of the plastic frame 1. . The attachment jig 22 is provided with a fastener 22a having a shank portion s.

  Therefore, the mounting mechanism in the present embodiment first has a beam portion 11 (an upper portion and a lower portion) for fixing the clamp 2 for hanging the pole member P between at least two plastic frames 1. Provided in two places.

  This embodiment is characterized in that a longitudinal groove 12 that is recessed inward is formed on the side surface of the beam portion 11 (see FIG. 2). The clamp 2 is usually composed of a part that clamps the pole and a jig that is attached to the support leg. The clamp part is connected so that the clamping part can turn freely when attached, and a fastening part that also serves as the pivot shaft is provided This is because it is disposed through the center of the mounting jig.

  Then, the fitting part 22 is fixed to the beam part 11 by fitting the shank part s of the fastening tool 22a to the recessed part of the vertical groove 12 so as to be joined, and fastening the fastening tool 22a. (See FIG. 3).

  In this embodiment, the fastening tool 22a of the mounting jig 22 of the clamp 2 is composed of a pair of bolt members and nut members, and the cylindrical portion or screw portion of the bolt member is used as a recessed portion of the vertical groove 12. It attaches and it fixes by screwing with the said nut member.

  In this manner, the clamp 2 can be attached to the beam portion 11, and then the pole member P is sandwiched between the plastic frame bodies 1 and 1 by sandwiching the pole member P, thereby forming a barricade. (See FIG. 4).

  Further, in the present embodiment, as shown in FIG. 5, the vertical groove 12 of the plastic frame 1 can be recessed from the bottom surface of the beam portion 11 to the inside, and at this time, the pole holding portion 21 and the mounting jig are attached. It is convenient to use a tool 22 that is hinged.

  Furthermore, in the present embodiment, the injection port 14 can be disposed to fill the weighted material inside the plastic frame 1, and the filler does not leak when compared with the conventional product. It can be effectively stabilized.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims. For example, The mounting position and quantity of the beam portion 11 of the plastic frame 1 and the formation position and quantity of the longitudinal groove 12 can be changed, and the fastening tool 22a of the clamp 2 is not limited to the bolt member and the nut member. Any one having a shank portion s may be used, and a rivet shape or a clip shape may be employed, and any of them is within the technical scope of the present invention.
