BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position adjusting device for adjusting a position of an outer wall PC plate temporarily attached to a frame structure via a fastener.

[0002]

2. Description of the Related Art An outer wall PC plate such as a curtain wall is attached to a floor or a beam of a skeleton structure via a fastener. This attaching operation is divided into three steps of temporary attachment, adjustment, and permanent attachment. Will be implemented. That is, first, the outer wall PC plate is lifted by a floor crane or the like, and attached to the floor or beams of the skeleton via a fastener to perform temporary attachment.

At this time, since the mounting accuracy has a great influence on the appearance and performance of the outer wall, a fastener is usually used.
A second fastener on the PC plate side is attached to the first fastener on the skeleton side so as to be movable by a predetermined amount in the front, rear, left and right directions so that the position can be adjusted in the front, rear, left, and right directions. Next, after adjusting the position so that the outer wall PC plate is at a target position, the outer wall P is fixed by the fastener.
Fix the C version.

Conventionally, the above-mentioned position adjustment work is performed by moving a PC plate with a lever block or using a bar.
The position adjustment of the outer wall PC plate is performed by shifting up the assembling position of the first fastener and the second fastener by pulling up between the first fastener and the second fastener.

[0005]

However, in the above-described position adjustment, it is difficult to finely adjust the position, and there is a problem that the operation involves danger and requires skill. For example, in bar operation, there is a danger that the tool may slip out of the fastener.

The present invention has been made in view of the above-mentioned problems, and has as its object to provide a device capable of finely adjusting the position of the outer wall PC plate by a simple operation.

[0007]

In order to achieve the above object, an outer wall PC plate position adjusting device of the present invention includes a first fastener having a rod portion fixed to a frame structure and extending upward, The position of the outer wall PC plate when the outer wall PC plate is attached to the frame structure is adjusted by the fastener having the second fastener fixed to the outer wall PC plate having the ring portion loosely inserted into the rod body portion. Device that
A mounting member having a through-hole that can be inserted into the rod portion of the first fastener; and a vertically rotatable connection to the mounting member so that the mounting member can approach and separate from the through-hole of the mounting member. And a lever extending upward and downward with the connecting portion as a boundary.

[0008]

The tool is a lever-equipped tool, and the tool is mounted by inserting a through hole of the mounting member into the rod of the first fastener, and the lower extension of the lever is opposed to the outer wall of the ring of the second fastener. In this state, by pulling the upper extension of the lever, the lower extension moves in the direction opposite to the upper extension with the connection with the mounting member as a fulcrum. As a result, the lower extension pushes the ring portion of the second fastener, whereby the outer wall PC plate moves.

At this time, the position of the lower extension portion of the lever with respect to the outer wall of the ring portion is changed by appropriately rotating the position adjusting device about the rod portion, and the first fastener, That is, the adjustment direction of the outer wall PC plate can be changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
First, a state where the outer wall PC plate 1 is temporarily attached to the floor 2 which is a frame structure will be described. As shown in FIG.
Is attached to the floor 2 via the first fastener 3 and the second fastener 4.

The first fastener 3 has a structure in which a screw rod 3b, which is a rod having an external thread threaded on the outer peripheral surface thereof, projects upward from a substrate 3a fixed to the floor 2, and the screw rod 3b is provided. 3b
The flat plate 3d inserted through the screw rod 3b is placed on the nut 3c screwed into the nut 3c. The second fastener 4 includes a ring portion 4a having a through hole 4c formed at the center thereof through which the screw rod 3b can be loosely inserted, and a PC plate mounting portion extending laterally from the ring portion 4a and mounted to the outer wall PC plate 1. 4
b, the through-hole 4c of the ring portion 4a is loosely inserted into the screw rod 3b of the first fastener 3, and the lower surface of the ring portion 4a is brought into contact with the flat plate 3d, thereby forming the outer wall P.
The C version 1 is temporarily attached to the floor 2.

Further, the position adjusting device 5 has a mounting member 7 having a through hole 7a which can be inserted into the screw rod 3b of the first fastener 3 and extending laterally. A lever 8 extending in the vertical direction is connected so as to be pivotable in the vertical direction. Here, the pivotable direction of the lever 8 is a direction in which the lever 8 approaches and separates from the through hole 7a of the mounting member 7.

Then, the position adjusting device 5 is attached to the upper end of the screw rod 3b of the first fastener 3 through the through hole 7 of the mounting member 7.
a, and is rotated about the screw bar 3b so that the line connecting the screw bar 3b and the lever 8 is located in the direction in which the PC plate 1 is to be moved, as shown in FIG. . Thereafter, by pulling the upper extension 8a of the lever 8 by a predetermined amount, the lower extension 8b of the lever 8 screws the ring 4a of the second fastener 4 around the connection between the mounting member 7 and the lever 8. The outer wall PC plate 1 is moved by pushing the rod 3b by a predetermined amount.

As described above, the above operation is repeated while appropriately changing the position of the lever 8, thereby adjusting the lateral position of the outer wall PC plate 1. In addition, outer wall PC
Adjustment of the plate 1 in the vertical direction is performed by turning the nut 3c of the first fastener 3. When the position adjustment is completed, the position adjusting tool 5 is removed, and a nut (not shown) is screwed into the tip of the screw rod 3b and tightened.

[0015]

[Effect of the Invention] As described above, the outer wall PC of the present invention is used.
With the plate position adjusting device, it is possible to adjust the position of the outer wall PC plate with a simple structure and without a skilled worker.
Further, since the position adjustment is simple as described above, the time required for the adjustment is reduced.
