BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kansashi bar support used for supporting a foundation bar, an underground beam bar, a column bar, or the like.

[0002]

2. Description of the Related Art Conventionally, as a kansashi muscle support, as disclosed in Japanese Utility Model Publication No. 60-32259,
A through hole is provided in the upper part of the vertical tube for inserting the horizontal support rod (kansashi muscle), and a wedge is inserted from above between the horizontal support rod inserted through the through hole and the inner surface of the vertical tube. Things are known.

[0003]

In the case of the above-mentioned conventional kansashi muscle support, the wedge is driven into the vertical pipe from above, and the horizontal support rod is fixed to the vertical pipe. If there is an error, the horizontal support rod will be insufficiently fixed after the wedge is driven in. Even if there is a lateral error in the mounting position of the horizontal support rod, the wedge cannot be pulled out. The position of the rod cannot be modified. Further, since the portion for fixing the horizontal support rod protrudes relatively larger than the horizontal support rod, the protruding portion hinders the lateral movement of the main bar along the horizontal support rod. There are two types of rods, one with a diameter of 22 mm and one with a diameter of 25 mm.
There is a problem that it cannot be used for supporting two types of horizontal support rods.

[0004]

In order to advantageously solve the above-mentioned problems, in the kansashi muscle support device of the present invention, a horizontal cylinder is fixed to an upper portion of a leg member, and a lower portion of the horizontal cylinder is provided in a lower portion of the horizontal cylinder. A plurality of kansashi muscle support members having slopes rising from one side to the other side in the width direction of the cylinder are fixed at intervals in the longitudinal direction of the horizontal cylinder, and the slopes of the horizontal cylinder are fixed. At the lower side plate, at the intermediate portion of each kansushi muscle support member, insert
Pressure contact between the bar support and the inner surface of the horizontal cylinder facing the slope
A screw for tightening a kansashi bar to be fixed at least is screwed.

PREFERRED EMBODIMENTS FIG. 1 to FIG. 7 there is shown a first embodiment of the present invention, the upper portion of the lower leg member 8 fixing the seat plate 7 at the lower end is fixed to the outer surface of the vertical tube 9, As a A tubular upper leg member 10 is slidably fitted into the vertical tube 9, a female screw member 11 is fixed to the vertical tube 9, and the upper leg member 10 is tightened by a bolt 12 screwed to the female screw member 11. The leg member 1 is formed and fixed, a through hole 13 for inserting a fixing member into the seat plate 7 is provided, and a temporary hole for placing a reinforcing steel material in an intermediate portion of the lower leg member 8 is provided. The receiving tube 14 is fixed.

The metal plate is subjected to press working to form a rectangular tubular horizontal cylinder 2, and both ends of a bottom plate 15 of the horizontal cylindrical body 2 are bent and raised, so as to extend in the width direction of the cylindrical body. A plurality of kansashi muscle bearing members 4 having a slope 3 rising from one side to the other side are formed, and each kansashi muscle bearing member is attached to a side plate 5 on the low level side of the slope 3 in the horizontal cylindrical body 2. A boss having an internal thread 16 is extruded at an intermediate portion of the screw 4, and a screw 6 for tightening a kansashi thread is screwed to the internal thread 16. The bottom plate 15 of the horizontal cylinder 2 is fixed to the upper part of the leg member 1 by welding.

FIGS. 8 and 9 show an example of use of the kansashi muscle support of the first embodiment, in which a seat plate 7 is placed on a discarded concrete 17 and fixed by anchor bolts (not shown). The middle portion of the kansashi muscle 18 is inserted into the horizontal cylindrical body 2 and placed on the slope 3 of the kansashi muscle supporting member 4, and the middle part of the kansashi muscle 18 is fastened by the kansashi muscle tightening bolt 6. The horizontal cylinder 2
Is pressed against the slope plate 3 of the kansashi muscle support member 4.

A plurality of upper rebars 20 are mounted on both left and right sides of the kansashi bar 18, respectively.
The upper portion of the stirrup 21 is placed on the lower side, and the lower reinforcing bar 22 is placed below the stirrup 21.

FIG. 10 to FIG. 12 show a kansushi bar support according to a second embodiment of the present invention, wherein the center of the bottom plate 15 of the horizontal cylindrical body 2 made of a steel pipe having a square cross section is a leg member. 1 is fixed to the upper end of the base plate 1 by welding, and both ends of the bottom plate 15 are bent and raised to form the kansashi muscle support member 4 having the slope 3. It is the same as the case of the tool.

FIG. 13 and FIG. 14 show a kansushi muscle support device according to a third embodiment of the present invention, in which a horizontal cylinder 2 extending in the front-rear direction is provided above a horizontal cylinder 2 extending in the left-right direction. 23 are fixed by welding, and both ends of the seat plate 24 in the horizontal cylindrical body 23 are bent and raised, so that the horizontal cylindrical body 2
A kansashi muscle support member 26 having a slope 25 that rises from one side in the width direction to the other side is formed. A female screw is formed on a side plate 27 of the horizontal cylinder 23 on the low level side of the slope 25. A boss is formed by extrusion, and a screw for tightening a wrench is screwed to the female screw. The other structure is the same as that of the first embodiment.

FIGS. 15 and 16 show the use state of the kansashi muscle support of the third embodiment.
The kansashi streaks 18 are inserted through and are fixed by the kansashi streak tightening bolts 6, and the kansashi streaks 29 are attached to the horizontal cylindrical body 23.
Is inserted and fixed by the kansashi muscle tightening bolt 28, the hoop muscle 30 is disposed on the kansumi muscle 18, and the upper kansima muscle 29 is disposed above the disposal hoop muscle 30. A large number of column reinforcing bars 31 are arranged between the hoop bars 30.

[0012]

According to the present invention, the horizontal cylinder is fixed to the upper part of the leg member, and the slope rising from one side in the width direction of the cylinder toward the other side is formed in the lower part of the horizontal cylinder. A plurality of kansashi muscle bearings having, provided at intervals in the longitudinal direction of the horizontal cylinder, the low-level side of the slope in the horizontal cylinder
On the sides, in the middle portion of the hairpin muscle bearings, insertion of
Of the kansasii muscle that has been
The kansashi muscle tightening bolt that is pressed into contact with the inner surface of the horizontal cylinder facing it and screwed into it is screwed. It is lifted along the slope of the slope of the muscle supporting member and comes into contact with the upper part of the interior of the horizontal cylinder.
Since the kansashi muscle is firmly fixed by being sandwiched between three points of the kansashi muscle tightening bolt, and the kansashi muscle is in contact with the upper part of the inside of the horizontal cylinder 2, a portion protruding upward from the kansashi muscle is in the horizontal cylinder. Since only the thin top plate is used, there is no hindrance when moving the main rebar along the kansashi muscle, and after the kansashi muscle is fixed, the kansashi muscle tightening bolt is loosened to loosen the kansashi muscle. The position of the muscle can be easily adjusted, and even if there is a slight difference in the diameter of the kansasis muscle, the kansasis muscle can be fixed and supported using one kansasii muscle support tool, especially ,
At the time of use, the weight of the rebar such as stirrup bars is applied to the kansashi bar tightening bolt via the kansashi bar, but since the stress is also distributed to a plurality of kansashi bar bearings,
The kansashi muscle tightening bolt is not easily deformed, and the kansashi muscle can be reliably held at a predetermined position.
