Description of the Related Art As shown in FIGS. 9 to 12, when an outer wall A of a building is conventionally lifted and attached to a steel beam D or the like, for example, the outer wall A is fixed to the left and right sides of a back surface a of the outer wall A, respectively. Horizontal projecting plate 12 of two outer wall angles 14
It is known that a method is used in which a shackle B or the like, which is locked to a lower end of a wire rope F connected to a crane, is engaged with the hanging hole 6 formed in the crane, and the hanging is performed.

[0003] The outer wall angle 14 is a back surface a of the outer wall A.
Plate 13 fixed to bolts 19 and the like, and fixed plate 1
3 is formed in a substantially L-shape which is wide in the lateral direction from a horizontal protruding plate 12 protruding from the upper edge.

The suspension hole 6 is formed inside a horizontal protruding plate 12. A joint bolt 7 is attached to the outside of the horizontal protruding plate 12 so as to project an upper end thereof upward, and a positioning nut 10 is screwed to the joint bolt 7. One side 11a of the outer wall fastener 11 is fitted between the horizontal protruding plate 12 of the joint bolt 7 and the positioning nut 10.

As shown in FIG. 11, the other side 11b of the outer wall fastener 11 is inserted through a fixing hole 16 formed in an upper flange d or the like of the steel beam D so that its upper end protrudes upward from below. An insertion hole 15 into which the upper end of the fixing bolt 17 is inserted is formed. A fixing nut 18 for fastening the outer wall fastener 11 to the upper flange d is screwed to an upper end of the fixing bolt 17.

As shown in FIG. 12, when the outer wall fastener 11 is fixed to the upper flange d of the steel beam D with the fixing bolt 17 and the fixing nut 18, the outer wall A is attached at a predetermined distance from the steel beam D. Adjustment of the mounting height of the outer wall A is performed such that after the outer wall A is mounted as described above, the dimension L between the outer wall fastener 11 and the horizontal protruding plate 12 becomes a desired set dimension L1. The measurement is performed by tightening or loosening the positioning nut 10 while measuring the pressure.

[0007]

However, in the prior art as described above, the hanging hole 6 for engaging the shackle B or the like is formed in the outer wall angle 14, and the horizontal protruding plate 12 is widened in the lateral direction. Therefore, when the hand is inserted into the work space E between the outer wall A and the steel beam D and the like and the fixing bolt 17 is inserted into the fixing hole 16 from below the upper flange d, the horizontal projecting plate 12 becomes an obstacle. Therefore, there is a problem that work is difficult.

Further, since the mounting height of the outer wall A is adjusted while measuring the dimension L with a scale or the like as described above, it takes a long time to mount the outer wall A.

Further, when removing the shackle B or the like after attaching the outer wall A, the horizontal protruding plate 12 is difficult to reach.
There is a problem that it needs to be performed below.

The column 3 is composed of, for example, a column 3a formed at the upper end and a prism 3b having a square cross section formed at the lower end. The suspension engaging portion 2 is provided at an upper end portion of the column 3 so that, for example, the direction perpendicular to the longitudinal direction of the column 3 and the surface direction thereof are parallel to the longitudinal direction of the column 3. Further, it has a suspension hole 6 for engaging the shackle B or the like described above.

The holding and fixing piece 4 is provided at a lower end of the support 3 on a side opposite to the suspending engaging portion 2, for example, in a direction perpendicular to the longitudinal direction of the support 3 and in a plane direction of the support 3. Are provided so as to be opposed to each other at predetermined intervals so as to be in a direction parallel to the longitudinal direction. As shown in FIG. 2, the distance C between these two holding and fixing pieces 4 is formed to be substantially the same as or slightly larger than the diameter so that the above-mentioned joint bolt 7 can be inserted between them. In addition, in this embodiment, the base 4b of the U-shaped member 4a is fixed to the lower end of the column 3 by welding or the like, so that the two holding and fixing pieces 4 are protrudingly provided. Can also be used.

The retaining plate 5 has a hook portion 8 formed on one side 5a for engaging with the joint bolt 7, and an external fitting hole 9 for externally fitting the support column 3 on the other side 5b. Is formed. The outer fitting hole 9 is fitted between the hanging engaging portion 2 of the column 3 and the holding and fixing piece 4 so as to be vertically movable.

Here, since the outer fitting hole 9 is formed in the same square shape as the cross-sectional shape of the prism portion 3b of the support column 3 in a plan view, the outer fitting hole 9 is pinched and fixed to the suspending engagement portion 2. Piece 4
On the upper side, ie, in the column portion 3a of the column 3, one side 5a of the retaining plate 5 is rotatable around the column 3, whereas on the lower side, ie, in the prism portion 3b, I cannot do it. Since the two holding and fixing pieces 4 are protruded in appropriate directions,
Joint bolt 7 inserted between the two fixing pieces 4
The stopper plate 5 can be slid from the column 3a to the prism 3b while the hook 8 is locked.

When the outer wall A is lifted by using the thus-configured hanging bracket 1, first, the shackle B and the like are engaged with the hanging holes 6 of the hanging engaging portion 2 and also shown in FIG. As described above, the positioning nut 10 is adjusted so that the space between the outer wall fastener 11 and the horizontal protruding plate 12 is kept at a predetermined interval. The horizontal projecting plate 12 does not need to be formed with the suspension holes 6 as described above, and therefore does not need to be wide. For example, as in this embodiment, the notch 12 a
Etc. can be formed. Then, the joint bolt 7 is inserted between the two holding and fixing pieces 4.
After being inserted so as to be sandwiched between the left and right holding pieces 4, the positioning nut 10 is tightened to hold the two holding and fixing pieces 4 from above and below with the outer wall fastener 11 and the horizontal projecting plate 12.

Next, as shown in FIG. 4, one side 5a of the stopper plate 5 is rotated while the stopper plate 5 is supported by the column portion 3a of the column 3, and the hook portion 8 is disengaged as shown in FIG. Lock to joint bolt 7. Then, as shown in FIG. 6, if the stopper plate 5 is slid downward, the outer wall A can be lifted without the hanging metal fitting 1 coming off. The shackle B and the like may be engaged after the hanging bracket 1 is attached.

That is, the suspension structure of the outer wall A according to this embodiment includes the fixed plate 13 fixed to the back surface a of the outer wall A and the horizontal protruding plate 12 protruding from the upper edge of the fixed plate 13. A substantially L-shaped outer wall angle 14;
And a positioning nut 10 screwed to the joint bolt 7 attached to the horizontal protruding plate 12 so as to protrude the upper end thereof upward, and between the horizontal protruding plate 12 and the positioning nut 10 of the joint bolt 7. In the hanging structure of the outer wall A to which the outer wall fastener 11 fitted to be vertically movable is attached, between the two holding and fixing pieces 4 of the hanging fitting 1, the joint bolt 7 is connected to the two holding and fixing pieces 4. Then, the positioning nut 10 is tightened and the positioning nut 10 is tightened to hold the two holding fixing pieces 4 from above and below with the outer wall fastener 11 and the horizontal protruding plate 12. The hook portion 8 is locked.

As shown in FIGS. 6 and 7, in order to attach the outer wall A thus lifted to the steel beam D or the like, the insertion hole 15 of the outer wall fastener 11 is inserted into the steel beam D as described above.
The outer wall A is arranged so as to communicate with the fixing hole 16. Then, a fixing bolt 17 is inserted from below the upper flange d into the fixing hole 16 and the insertion hole 15 so that an upper end thereof protrudes upward, and a fixing nut 18 is screwed into the fixing bolt 17 to tighten the outer wall. A can be attached at a predetermined interval from the steel beam D.

In this case, as shown in FIG. 8, since the notch 12a is formed in the horizontal protruding plate 12, there is an advantage that the work space E is easily accessible even when the fixing bolt 17 is mounted. is there. As described above, if the hanging metal fitting 1 is used, it is not necessary to form the hanging hole 6 for engaging the shackle B or the like in the horizontal projecting plate 12. 12a can be formed, or the width can be reduced in advance, and the outer wall A can be easily attached.

After the outer wall A is attached with the fixing bolts 17 and the fixing nuts 18, the reverse procedure is performed, that is, the stopper plate 5 is slid to the upper cylindrical portion 3a, and the stopper plate 5 is turned. By moving the hook portion 8 from the joint bolt 7 and then loosening the positioning nut 10 a little, the hanging bracket 1 can be removed. The removal work in this case can be performed above the horizontal protruding plate 12, so that it is simple.

As shown in FIG. 7, the height of the holding and fixing piece 4 is set to the set dimension L1 between the outer wall fastener 11 and the horizontal protruding plate 12 after the outer wall A is attached to the steel beam D or the like. If they are made to have substantially the same dimensions in advance, the outer wall A will already be mounted at an appropriate height when the hanging fitting 1 is removed as described above. for that reason,
There is an advantage that it is not necessary to adjust the mounting height of the outer wall A.

In this embodiment, the hanging engaging portion 2 is formed in a plate shape, but the present invention is not limited to this. Alternatively, the hanging engaging portion 2 may be provided by attaching a wire or the like to the upper end of the column 3. Alternatively, it may be provided by forming the suspension hole 6 at the upper end of the column 3. Further, the cross-sectional shape of the prism portion 3b of the support column 3 and the shape of the external fitting hole 9 of the retaining plate 5 are not limited to squares, and may be any shape that does not allow the retaining plate 5 to rotate. I just need. In addition, since the columnar portion 3a only needs to be able to rotate the stopper plate 5, the cross-sectional shape need not be circular.

[0028]

As described above, according to the first and second aspects of the present invention, the outer wall can be lifted by using the above-configured hanging metal fitting, and the angle of the outer wall angle can be increased as in the prior art. Since it is not necessary to form a hanging hole for engaging a shackle or the like in the horizontal protruding plate, the width of the horizontal protruding plate can be reduced. Therefore, the work space can be easily accessed even when the fixing bolt is attached, and the outer wall can be easily attached.

Further, the hanging metal can be removed above the horizontal projecting plate, and the shackle or the like may be kept engaged with the hanging metal, so that the work after the outer wall is attached is simple.

According to the third aspect of the present invention, the height of the holding and fixing piece is formed to be substantially the same as the set dimension between the outer wall fastener and the horizontal protruding plate after the outer wall is attached to a steel beam or the like. Therefore, when the hanging bracket is removed, the outer wall is already mounted at an appropriate height. for that reason,
It is not necessary to adjust the mounting height after the outer wall is mounted, and the working efficiency can be greatly improved.
