Description

The present invention relates to a panel hanger for hoisting a panel having notches at both ends of its upper surface, and a method for lifting a panel using the same.

Soundproof panels are installed along the outer edge of the road to prevent noise from passing vehicles from leaking outside.
To construct such soundproof panels, pillars with an H-shaped cross section are erected at appropriate intervals along the outer edge of the road, and the soundproof panels are lifted by a crane and dropped into the grooves of the adjacent pillars. It is common to stack them in stages.

Conventionally, in order to lift a soundproof panel, a belt sling was passed around the soundproof panel, and a hook hung from a crane or the like was hooked to the eye of the belt sling.
In such a method, it is not only troublesome to attach the belt sling to the soundproof panel, but also requires complicated work such as removing the belt sling even after the soundproof panel is dropped between the columns.

Further, Patent Document 1 discloses that the width is narrower than the inner shape of the notch provided at the left and right ends of the upper surface of the soundproof panel, and the length is greater, and the soundproof panel is hung by a hanging tool at a position eccentric from the center in the longitudinal direction. A technique is described in which a locking tool is inserted into a notch of a soundproof panel, and is engaged with the inner edge of the notch to suspend the soundproof panel.
The locking tool disclosed in Patent Document 1 can be easily locked by simply coming into contact with the inner edge of the notch, and even after being dropped between the supports, it is only necessary to pull it out from the notch, so it is effective for soundproofing. There is no need to hang the belt sling on the panel or remove the belt sling.

However, the locking tool as described in Patent Document 1 is made of a single flat plate and is simply hooked onto the inner edge of the notch, so the locking state is very unstable. Therefore, if the soundproof panel is tilted during lifting, it is likely to escape from the notch, and as a result, there is a risk that the soundproof panel will fall when it is blown by strong winds.
In addition, although soundproof panels are generally stacked and transported, such locking devices cannot be stably locked to the inner edge of the notch until the soundproof panels are erected and hoisted. It was hard work to erect the soundproof panels, requiring the assistance of

The problem to be solved by the present invention is to create a panel that can be hung stably, that will not come off even if the panel is tilted, and that can be pulled down from above to stand up stacked panels. An object of the present invention is to provide a hanging device and a method for lifting a panel using the same.

The present invention relates to a panel hanger for hoisting a panel having notches at both ends of a top plate, and includes a hoisting part that can be pulled from above and a locking part provided at a lower part of the hoisting part, Clamping parts are formed on both sides of the locking part to removably clamp both sides of the top plate of the panel across the notch.

The locking portion includes an upper plate and a lower plate that are located above and below the notch and are movable toward and away from each other, and both sides of the upper plate and the lower plate engage the notch of the top plate when approaching. In some cases, the sandwiching portions may be used to sandwich both sides.

In this case, a spring is disposed between the upper plate and the lower plate to bias the upper plate and the lower plate in the direction of separation, and by rotating the upper plate and the lower plate in the forward and reverse directions, the upper plate and the lower plate can be separated. It is desirable to have a clamp lever for moving the

The length of the long side of the upper plate is wider than the width of the notch, the length of the long side of the lower plate is larger than the width of the notch, and the length of the short side of the lower plate is wider than the width of the notch. It is best to make it shorter than the width of the notch.

The method for lifting a panel according to the present invention includes arranging the panel hanging tools at both ends of the top plate of the panel, and forming the hanging parts on both sides of the top plate with the notch sandwiched therebetween. The panels are held from above and below by the holding parts, and the lifting parts are pulled from above to lift both sides of the panel.

The locking portion includes an upper plate and a lower plate that can be moved toward and away from each other, and a spring is disposed between the upper plate and the lower plate to bias the upper plate and the lower plate in a direction of separation, and the upper plate and the clamping portions are formed on both sides of the lower plate, and after placing the upper plate and the lower plate above and below the notch, respectively, the clamp lever is rotated in the forward direction to connect the upper plate with the clamping portion. By approaching the lower plate against the biasing force of the spring, the clamping portions clamp both sides of the top plate across the notch, and the clamp lever is rotated in the opposite direction, The upper plate and the lower plate may be separated by the biasing force of the spring.

The length of the long side of the upper plate is wider than the width of the notch, the length of the long side of the lower plate is larger than the width of the notch, and the length of the short side of the lower plate is wider than the width of the notch. The upper plate and the lower plate are separated from each other by a width shorter than the width of the notch, and then the lower plate is rotated so that the short side direction of the lower plate coincides with the width direction of the notch. The panel hanger may be removed from the panel by pulling the lower plate upward through the panel.

According to the present invention, since the clamping parts formed on both sides of the locking part clamp the both sides of the notch in the top plate of the panel, the panel hanging tool can be stably attached to the panel, and the hanging part can be stably attached to the panel. The panel hanging tool does not come off even if the panel tilts or vibrates, increasing the safety of panel lifting work.
In addition, it is possible to stably attach the panel hanging equipment even when the panel is in a state of being fallen down, and by pulling the lifting part from above using a crane, etc., the fallen panel can be erected. The labor required for lifting work is reduced.

If both sides of the upper plate and the lower plate, which can be brought into and out of contact with each other, are used as clamping parts, the clamping parts on both sides can be attached and detached at the same time by simply bringing the upper plate and the lower plate into contact with and away from each other.

By arranging springs that bias the upper and lower plates apart, the open upper and lower plates can be easily placed above and below the notch, and can be quickly clamped by simply rotating the clamp lever. can be attached to and removed from the top plate.

If the length of the long side of the lower plate is larger than the width of the notch, and the length of the short side of the lower plate is shorter than the width of the notch, the upper plate and lower plate can be separated, and then the lower plate The lower plate can be pulled upward by rotating the short side so that it matches the width of the notch, even if there is not enough space outside the width of the sound insulation panel to pull out the locking part. , it is possible to remove the suspension from the acoustic panel.

Furthermore, the upper end of a screw shaft 102 is fixed to the lower end of the lifting section main body 100.

The locking part 11 includes an upper plate 13 and a lower plate 14 that face each other vertically, and both sides of the upper plate 13 and the lower plate 14 can be attached and detached from each other on both sides of the notch 23 of the top plate 22 of the panel 2. These are sandwiching parts 15a and 15b that are sandwiched between the two.
The upper plate 13 has a substantially rectangular shape with long sides longer than the width of the notch 23 of the panel 2. A bar 130 is attached to the lower surface of the upper plate 13 along one short side.
A lever holder 131 having a square cross section is fixed to the upper surface of the upper plate 13. The lower piece of the lever holder 131 extends longer than the upper piece toward one side in the short side direction of the upper plate 13, and a contact bolt 132 that can come into contact with the top plate 22 of the panel 2 is attached to this extended part. It will be done.
The upper plate 13 and the lever holder 131 are slidably inserted into the screw shaft 102 of the lifting part 10.

The lower plate 14 is a rectangle in which the length of the long side is longer than the width of the notch 23 of the panel 2 and the length of the short side is shorter than the width of the notch 23. A bar 140 is attached to the upper surface of the lower plate 14 along one short side. One end of the bar 140 is short so as not to reach one long side of the lower plate 14.
A chamfered portion 141 is formed at the corner of the lower plate 14 where the short side opposite to the bar 140 and one long side intersect.
Further, the lower plate 14 is inserted through a screw shaft 102 below the upper plate 13, and the lower plate 14 is restricted from descending by a nut 103 screwed onto the screw shaft 102.

The upper plate 13 and the lower plate 14 are such that the bar 130 of the upper plate 13 and the bar 140 of the lower plate 14 are located on opposite sides in the long side direction, and the contact bolt 132 provided on the lever holder 131 and the lower plate 14 The corner portions 141 of the two are arranged to face each other so that they are located on the same side in the short side direction.
Further, a spring 16 is arranged between the upper plate 13 and the lower plate 14 to bias the upper plate 13 and the lower plate 14 in the direction of separation.

The clamp lever 12 is provided with a grip portion 120 at one end and a cam portion 121 at the other end. The cam part 121 is bifurcated, and the lower part of the lifting part main body 100 is sandwiched between the cam part 121 and is rotatable to the lifting part main body 100 around a shaft 122 that passes through the cam part 121 and the lifting part main body 100. installed.

The side edge of the cam portion 121 is curved with a predetermined cam lift amount, and is in contact with the upper surface of the lever holder 131. That is, the cam portion 121 has a short diameter portion and a long diameter portion around the shaft 122, and the distance between the shaft 122 and the side edge of the cam portion 121 can be changed according to the rotation angle of the clamp lever 12. It becomes.

As shown in FIGS. 1 and 2, when the clamp lever 12 is upright and the short diameter portion of the cam portion 121 is in contact with the upper surface of the lever holder 131, the biasing force of the spring 16 causes the upper plate 13 to The lower plate 14 is spaced apart.
On the other hand, as shown in FIGS. 4 and 5, when the clamp lever 12 is rotated in the forward direction (clockwise in FIG. 5), the long diameter portion of the cam portion 121 comes into contact with the upper surface of the lever holder 131. , the upper plate 13 is pushed down relative to the lower plate 14 against the urging force of the spring 16, and the upper plate 13 and the lower plate 14 approach each other.
When the clamp lever 12 is rotated in the opposite direction (counterclockwise in FIG. 5), the upper plate 13 and the lower plate 14 are separated again.

When hoisting the panel 2 using the panel hanging tool 1, as shown in FIG. , the panel hanging tool 1 may be attached to the panel 2, and the wire A may be attached immediately before lifting). Then, with the clamp lever 12 in an upright state (see FIG. 2, etc.), the upper plate 13 and lower plate 14 of the hanging tool 1 are separated, and the clamping parts 15a and 15b on both sides are left open. In this state, the long side directions of the upper plate 13 and the lower plate 14 are aligned with the width direction of the notch 23 (thickness direction of the panel 2), and the lower plate 14 is inserted from the outside in the width direction of the panel 2 to the flange of the side frame 21. The upper plate 13 and the lower plate 14 are placed above and below the notch 23, respectively.
At this time, in the panel hangers 1 placed on both the left and right sides of the panel 2, the abutment bolts 132 provided on the bar 130 of the top plate 13 and the lever holder 131 abut against the top surface of the top plate 22 of the panel 2. It can be installed like this. In addition, the panel 2 is arranged so that the cornered portion 141 of the lower plate 14 faces the web of the side frame 21 of the panel 2, and the positive direction of the rotation operation of the clamp lever 12 is the direction in which the panel 2 is tilted inward in the width direction. The panel hanging tools 1 are arranged symmetrically on both the left and right sides of the panel.

Next, as shown in FIG. 6C, the clamp lever 12 is rotated in the forward direction to bring the upper plate 13 and the lower plate 14 closer together. Since the upper plate 13 is in contact with the top plate 22 of the panel 2 and cannot be lowered, the lower plate 14 rises, and the clamping parts 15a and 15b on both sides of the upper plate 13 and the lower plate 14 close, and the top plate 22 of the panel 2 Both sides of the notch 23 are held.
Since the bar 130 provided on the lower surface of the upper plate 13 contacts the upper surface of the top plate 22, and the bar 140 provided on the upper surface of the lower plate 14 contacts the lower surface of the top plate 22, the clamping portions 15a and 15b To stably hold a top plate 22.
Also, since one end of the bar 140 of the lower plate 14 does not reach the long side of the lower plate 14, the curved corner portion formed by bending the extension 22' of the top plate 22 from the web of the side frame 21 Never collide.

In this way, the panel hanging tools 1 are attached to both sides of the top plate 22 of the panel 2, and the panel 2 is lifted by pulling the wire A connected to the wire attachment part 101 from above.
In the panel hanging tool 1, since the clamping parts 15a and 15b provided on both sides of the upper plate 13 and lower plate 14 of the locking part 11 clamp the top plate 22, even if the panel 2 is tilted, There is no fear that the panel hanger 1 will come off and the panel 2 will fall.

The lifted panel 2 is dropped from above between adjacent pillars having an H-shaped cross section.
After installing the panel 2 in a predetermined position, the panel hanging tool 1 is removed.
When removing the panel hanger 1 from the panel 2, as shown in FIG. 12 in the opposite direction to separate the upper plate 13 and lower plate 14, and release the top plate 22 of the panel 2 from the holding parts 15a and 15b.

Next, as shown in FIG. 7A, the panel hanger 1 is rotated together with the lower plate 14, and the end portion of the lower plate 14 where the cornered portion 141 is formed is rotated.
Since the short side of the lower plate 14 is shorter than the width of the notch 23, the lower plate 14 can be pulled upward through the notch 23, and even if the gap between the outer edge of the panel 2 in the width direction and the column is narrow, the panel The hanger 1 can be removed from the panel 2.
Further, since the lower plate 14 has the cornered portion 141, the corner portion does not get caught on the inner circumferential surface of the side frame 21 when the lower plate 14 is rotated.

As shown in FIG. 8(a), when lifting a large number of stacked panels 2 one by one from above, as shown in FIG. The wires A attached to the panel hangers 1 on both sides are pulled from above by a crane or the like.
Then, the panel 2 is raised with the top plate 22 to which the panel hanging tool 1 is attached facing up, and is lifted up in an upright state.
Since the clamping parts 15a and 15b on both sides of the locking part 11 clamp the top plate 22 of the panel 2, the panel hanger 1 does not come off when the panel 2 is raised from a collapsed state.

[Second embodiment]
FIG. 9 shows a second embodiment of the invention.
In the second embodiment, the lifting section main body 100 of the lifting section 10 is bent in the long side direction of the upper plate 13 and the lower plate 14 at the axially central portion.
Therefore, even if the top plate 22 is inclined in the thickness direction of the panel 2, the panel 2 can be lifted vertically and installed between the supports without the panel 2 tilting when lifted.
Other structures and usage methods are the same as in the first embodiment.

The present invention is not limited to the embodiments described above. Examples include the following:

In the above embodiment, the upper plate and the lower plate are brought into contact with each other by rotating the clamp lever, but the nut installed above the upper plate and screwed onto the screw shaft is rotated. , the upper plate and the lower plate can also be brought into contact with each other and separated from each other.

In the above embodiment, in order to stably hold the top plate of the panel, bars are attached to the lower surface of the upper plate and the upper surface of the lower plate. The ends may be bent upward.
