Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a countersheath support tool used for supporting a base rebar, an underground beam rebar, a column rebar, or the like.

[0002]

[Prior art]

 Conventionally, as a kanzashi muscle support, as disclosed in Japanese Utility Model Publication No. 60-32259, a through hole is provided in the upper part of a vertical pipe for inserting a horizontal bearing rod (kanzashi muscle), and the through hole is formed in the through hole. It is known that a wedge is inserted from above between the inserted horizontal support rod and the inner surface of the vertical pipe.

[0003]

[Problems to be solved by the device]

 In the case of the conventional kanzashi muscle support, since the wedge is driven into the vertical pipe from above and the horizontal support rod is fixed to the vertical pipe, if the diameter of the horizontal support rod has an error, the wedge is driven. After that, the horizontal support rod is not fixed enough, and even if there is a lateral error in the mounting position of the horizontal support rod, the wedge cannot be removed, so it is not possible to correct the position of the horizontal support rod. Can not. Further, since the portion for fixing the horizontal supporting rod projects relatively larger than the horizontal supporting rod, the projecting portion becomes an obstacle when the main bar moves laterally along the horizontal supporting rod, and further, the horizontal supporting rod There are two types of rods, one having a diameter of 22 mm and the other having a diameter of 25 mm. However, the conventional kanzashi muscle support device has a problem that it cannot be used to support two types of horizontal bearing rods.

[0004]

[Means for Solving the Problems]

 In order to advantageously solve the above-mentioned problem, in the knitting muscle support of the present invention, the horizontal cylinder 2 is fixed to the upper part of the leg member 1, and the horizontal width of the horizontal cylinder 2 is fixed to the lower part of the horizontal cylinder 2 in the width direction of the cylinder. A plurality of kanzashi muscle supporting members 4 having slopes 3 that rise from one side to the other side are fixed at intervals in the longitudinal direction of the horizontal cylinder 2, and the slopes 3 of the horizontal cylinder 2 are fixed. The bolts 6 for tightening the hook muscle are screwed onto the side plate 5 on the low level side of the above at the intermediate portion of each hook muscle supporting member 4.

[Effect of device]

 According to the present invention, the horizontal cylinder 2 is fixed to the upper part of the leg member 1, and the slope 3 that rises from one side in the width direction of the cylinder to the other side is fixed to the lower part of the horizontal cylinder 2. A plurality of the kanzashi muscle supporting members 4 are fixed at intervals in the longitudinal direction of the horizontal tubular body 2, and the side plate 5 on the low level side of the slope 3 of the horizontal tubular body 2 is provided with Since the bolt 6 for tightening the knitting muscle is screwed in the middle portion, the knitting muscle 18 is inserted into the horizontal cylindrical body 2 and tightened with the bolt 6 for tightening the knitting muscle, so that the knitting muscle 18 is supported by the knitting muscle. The member 4 is lifted along the slope of the slope 3 and comes into contact with the upper part inside the horizontal cylinder 2, so that the knitted line 18 is formed on the upper part of the inner surface of the horizontal tube 2, the slope 3, and the bolt 6 for tightening the knitted line. It is sandwiched between points and firmly fixed, and Since 18 is in contact with the upper part inside the horizontal cylinder 2, only the thin upper surface plate 19 of the horizontal cylinder 2 protrudes upwards from the kanzashi muscle 18. When moving, it does not cause any hindrance, and after fixing the crease muscle 18, the position of the crease muscle 18 can be easily adjusted by loosening the crepe muscle tightening bolt 6. Moreover, even if there is a slight difference in the diameter of the kanzai muscle 18, it is possible to fix and support the kanzai muscle 18 by using one knitting muscle support tool.
