Definitions

  • the present invention relates to a clamp used for connecting steel pipes such as temporary scaffolds and shelves. Background technology
  • the clamp generally used in the past has a holder and one end of the holder pivotally connected, the base of the tightening bolt is pivotally connected to the other end of the holder, and a U-shaped groove is provided at the other end of the holder.
  • the tip of the bolt is fitted into this concave groove, and the nut is screwed into the bolt and tightened.
  • the inventor has previously developed a clamp disclosed in Japanese Utility Model Publication No. 57-18707, but the present invention further improved this and provided a bolt insertion hole. Instead, they devised a structure that can be applied to pipes of different dimensions by clamping the holder with stepped wedges. Disclosure of the invention
  • one end of the holder 1 and one end of the holder 3 are pivotally connected, and both bases of the inverted concave auxiliary holder 2 are pivotally connected to the other end of the holder 1.
  • a rounded window 9 for inserting a step-shaped wedge 8 at the front end of the auxiliary holding body 2 is provided.
  • the auxiliary holding The rest 2 covers the upper part of the holder 3, and the groove 6 provided in the holder 3 for a thick pipe and the groove 7 and the round window provided in the auxiliary holder 2 for a thin pipe.
  • Drive a stepped wedge 8 into 9 The pipe is held by the body 2 by crimping.
  • the phase of the stairs of the step-shaped wedge 8 is changed so that the half of the stairs abuts on the side of the support holder 2 that makes uniform contact with the receiving part and the wedge with the wedge. 8 prevents loosening and falling off.
  • the holding body 1, the holding body 3, and the auxiliary holding body 2 may be formed in a square shape.
  • FIG. 1A is a side view showing an embodiment of the present invention.

  • FIG. 2 shows a front view of the embodiment in the case of a thick pipe
  • FIG. 3 shows a front view of the embodiment in the case of a thin round pipe.
  • the concave groove 6 of the holder 3 for driving the wedge 8 is used.
  • one end of the holder 1 and one end of the holder 3 are pivotally connected by pins 4.
  • both bases of an inverted concave auxiliary holding body 2 are pivotally connected by pins 5, and at the tip of the auxiliary holding body 2, a round window for press-fitting a wedge 8.
  • Part 9 is provided.
  • the pipe held in the holder 1 and the holder 3 is covered from above with the auxiliary holder 2 and the concave grooves 6 and 7 and the round corners previously provided in the auxiliary holder 2 are provided. Press the step-shaped wedge 8 into the window 9. At this time, the stepped wedge 8 is in full contact with one side of the auxiliary holder 2 and the seat of the auxiliary holder 2, and the other seat is changed in phase so that half of the steps come into contact with it to prevent the wedge from falling off. We are dealing.
  • Fig. 1 shows an example of using a stepped wedge.
  • Figures 2 and 3 show the case of holding a round pipe, but when holding a square pipe of different diameter, the holding body 1, the holding body 3, and the auxiliary holding body 2 may be formed in a square shape. .
  • the present invention has the above-described configuration, and has a rounded window 9 for inserting a step-like wedge 8 at the tip of the auxiliary holder 2, and covers the auxiliary holder 2 with the holder 3
  • a stepped wedge 8 is press-fitted into the concave grooves 6 and 7 provided in advance in the body 3 and the rounded window 9 of the auxiliary holding body 2 to hold a thick eve and a thin pipe.
  • the operation is extremely simple and the use of the wedge 8 of the staircase ⁇ ensures that the pipe is held.
  • the holding body 1, the holding body 3, and the auxiliary holding body 2 are formed in a rectangular shape, it is possible to hold square pipes having different diameters.

Abstract

L'invention supprime les difficultés de manipulation des colliers de serrage à vis actuels et procure un serrage sûr. Un corps de serrage, qui comprend deux sillons concaves, est monté de façon à pouvoir pivoter sur une extrémité d'un élément de maintien, grâce à une broche. Un élément de maintien auxiliaire, à forme concave inverse, est monté de façon à pouvoir pivoter sur l'autre extrémité de cet élément de maintien grâce à une autre broche. Pour serrer un tuyau, on forme une fenêtre mi-ronde mi-carrée, permettant l'insertion d'un coin à gradins, dans l'élément de maintien à forme concave inverse, et le corps de serrage est recouvert par l'élément de maintien auxiliaire, ce qui permet d'adapter par pression le coin à gradins dans la fenêtre.
