Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a jig for adjusting the position of a ring fastener.

[0002]

2. Description of the Related Art As shown in FIG.
Is a fastener base c attached to a flange of a beam (H-shaped steel) b on the skeleton side, a bolt d protruding from the fastener base c, and a nut e screwed to the bolt d.
And a ring member h inserted into the bolt d via the washer f next to the nut e and driven into the PC curtain wall g.

[0003] By rotating the nut e to move the ring member h in the axial direction of the bolt d, the PC
The height and the horizontal position of the curtain wall g are adjusted. In this case, the ring fastener a is surrounded by the slab concrete j via the concrete stopper i,
Since the nut e is located below the top end of the slab, the dedicated spanner k having a bent handle is set on the nut e by groping and rotated.

[0004]

However, the nut e is rotated by the spanner k having a curved handle as described above, and the PC is rotated.
In the method of adjusting the position of the curtain wall g, since the entire load of the PC curtain wall g acts on the nut e via the ring member h and the washer f, a great amount of labor is required to rotate the nut e. However, there is an inconvenience that the work of adjusting the position of the PC curtain wall g is extremely troublesome, in combination with the difficulty in handling the spanner k.

An object of the present invention is to provide a ring fastener position adjusting jig which can greatly improve the efficiency of curtain wall position adjusting work. I do.

[0006]

In order to achieve the above object, a ring fastener position adjusting jig according to the present invention comprises a fastener base attached to a skeleton side and a bolt protruding from the fastener base. A nut screwed into the bolt, and a ring member inserted into the bolt via a washer next to the nut and driven into a curtain wall, and rotating the nut to rotate the ring member. In a ring fastener position adjusting jig which is moved in the axial direction of the bolt to adjust the position of the curtain wall, a plurality of hooks arranged along the circumferential direction of the washer and hooked on the lower surface of the washer. A jig main body including a connecting portion that connects the stopping portion and the plurality of hanging portions above the bolt, and a jack interposed between the connecting portion and the bolt. Characterized by comprising.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A position adjusting jig for a ring fastener according to an embodiment of the present invention will be described below with reference to FIG.

First, the ring fastener 1 will be described. The ring fastener 1 includes a fastener base 5 attached to a flange 2 a of a beam (H-shaped steel) 2 on the skeleton side via a bolt 3 and an adjusting nut 4. A bolt 6 protrudes from the fastener base 5, and an adjusting nut 7 is screwed to the bolt 6. A ring member 9 is inserted into the bolt 6 via a washer 8 next to the adjustment nut 7, and the ring member 9 is driven into a PC curtain wall 10. The ring fastener 1 having such a configuration is surrounded by slab concrete 12 via a concrete stopper 11, and the adjusting nut 7 is located below the top end of the slab.

Next, the position adjusting jig 20 will be described. The positioning jig 20 comprises a jig main body 21 and a hydraulic jack 22, and the jig main body 21 is provided with bolts 6 on both sides of the ring member 9, respectively. Hooks 23 extending in the axial direction of the
And a connecting portion 24 that connects above.

At the lower end of each of the hooks 23, hooks 23a extend inward, and each hook 23a is hooked on the lower surface of the washer 8. Hydraulic jack 2
Numeral 2 is interposed between the distal end surface of the bolt 6 and the connecting portion 24 of the jig body 21, and the hydraulic supply hose 25 of the hydraulic jack 22 is connected to a hydraulic supply source (not shown).

In order to adjust the height and horizontal position of the PC curtain wall 10, the hydraulic jack 22 is driven to lift the jig body 21, the washer 8, the ring member 9 and the PC curtain wall 10 together and raise them. When the height and the horizontal position of the PC curtain wall 10 are determined, the adjustment nut 7 is formed using a bent wrench as in the prior art.
Is rotated to the position of the washer 8, the hydraulic jack 22 is stopped in this state, and the load on the PC curtain wall 10 is received by the adjusting nut 7. With this, PC
The position adjustment of the curtain wall 10 is completed.

As described above, in this embodiment, the height and the horizontal position of the PC curtain wall 10 are adjusted by lifting the PC curtain wall 10 using the hydraulic jack 22, so that the position adjustment is facilitated. Since the load on the PC curtain wall 10 does not act at all when the adjustment nut 7 rotates, the adjustment nut 7 can be easily rotated. As a result, the position of the PC curtain wall 10 can be reduced. The work efficiency of the adjustment work can be greatly improved.

[0013]

As is apparent from the above description, according to the present invention, the height and horizontal position of the curtain wall can be adjusted by lifting the curtain wall using the jack, so that the position adjustment can be easily performed. Can be done to
Moreover, since no load is applied to the curtain wall when the adjustment nut is rotated, the adjustment nut can be easily rotated, and as a result, the work efficiency of the curtain wall position adjustment operation is greatly improved. Is obtained.
