The anti-vibration frame 2 has guide rollers 22 at predetermined positions on both sides, and the guide rollers 22 are interlocked with each other so as to be movable on the channel member 4. The channel member 4 is formed of a large cutout 40 and a small cutout 42, respectively, where the opposite positions of the upper end portions are cut off.

The large cutout 40 is used as a passage for inserting and installing the anti-vibration frame 2 into the channel member 4 in the direction of the arrow in the drawing, and the small cutout 42 connects the guide roller 22 to the channel member 4. It is used as a passage for charging.

On the other hand, as the channel member 4, 'I' section steel can be preferably applied, the position fixing roll 44 inside the sleeve 45 at a position that can support one side of the dustproof frame (2) It is rotatably supported by the shaft.

The position fixing roll 44 is arranged in a plurality of spaced intervals inside the channel member 4, these are the difference in the thickness of the dustproof frame 2 and the internal width of the channel member 4 as shown in FIG. The vibration of the anti-vibration frame (2), which may be caused by the act to prevent the occurrence. For this reason, the anti-vibration frame 2 can be installed stably by inserting several sheets into the channel member 4 in order.

In addition, the lower side of the channel member 4 is provided with a jaw (not shown) to support the lower end of the first dust-proof frame 2 to be loaded inside, and the dust-proof frame 2 thereafter is first charged to the lower side. It is supported on the upper end of the dustproof frame (2).

Derek 50 having pulleys 48 on both sides is integrally installed at the upper end of the channel member 4 so that the dust-proof frame 2 which is charged in sequence as described above can be lifted.

That is, the rope (R) shown in dashed lines in FIG. 3 is released from the chain block or winch (W) disposed on either side of the opposing pulley (48) via the lower side of the dustproof frame (2) and the opposite pulley (48). By being connected to) can be lifted as it is without left and right unbalance by the chain block or winch (W). In order to bind the rope R as described above, the vibration isolating frame 2 has a pin or a roller 24 for each predetermined portion of the lower side.

In addition, between the dustproof frame 2 and the channel member 4 are integrally connected to each other through a suitable bracket, or two pin holes at predetermined positions at intervals corresponding to the height of the dustproof frame 2 as shown. 54) should be drilled horizontally, so that the moved dust-proof frame 2 can be integrally connected with a pin or the like not shown.

It is better if the dustproof frames 2 arranged up and down are provided with means that can be interconnected similarly to the above. However, a means for integrally connecting the dustproof frames 2 to each other is not necessary to implement the present invention.

A hook 52 is attached to a predetermined position at a position facing the outer wall of the building in the channel member 4 so that it can be caught by a suspension hole 6 having a configuration as shown in FIG. . The suspension hole 6 is fixed to each edge of the slab constituting each floor of the building guides the channel member 4 to be elevated without shaking left and right.

Since the apparatus of the present invention is installed by installing the dustproof frame 2 manufactured to a predetermined standard in the channel member 4 vertically disposed on the outer wall of the building as described above, it does not occupy a large place in the field, so it is difficult to use it. easy.

In addition, since the dustproof frame 2 having a predetermined size can be loaded and carried, transportation can be simplified.

On the other hand, the suspension hole 6 shown in Figure 4 has a flat base body 62, and the base body 62 has an elliptical shape so that it can be fixed to the base of the building floor to be able to be somewhat movable with an anchor bolt or the like. The bolt hole 64 is retained, and the wall 66 of a predetermined shape is integrally formed upward from the base body 62.

It adheres to 73 and limits the rotational standing of the hanger 72 to the range of about 70-80 degree.

In addition, a pair of guide rollers 74 are disposed on the front side of the hanger 72, and a part of the wall 66 surrounding the guide rollers 74 extends to the outside to form the protruding wall 76. Doing.

A pin insertion hole 80 into which the safety pin 78 is inserted is provided in the protruding wall 76.

As shown in FIG. 5, the suspension tool 6 having such a configuration allows the corresponding end of the channel member 4 to pass through between the guide rollers 74, and at the same time, the channel member 4 once passed through is hooked. The hanging on the hanger 72 is suspended from the building outer wall. In addition, the suspended state is double locked by the pin 78 inserted or removed by the operator, in which case the pin 78 is supported through the through hole 46 of the channel member 4. .

The channel member 4 is moved up and down depending on a separate lifting means. In this case, when the suspension tool 6 has a guide roller 82 at a predetermined position, the channel member 4 is lifted. The rope (R) for easy extension to the lower side can be hooked to the lower hook 52 of the channel member 4, thereby improving the ease of operation.

When the channel member 4 is moved up and down, a connection with the dustproof frame 2 through the pin hole 54 has to be partially released. In this case, since the dustproof frame 2 is disconnected on only one side, and the released side is supported on the surface contact by the channel member 4 which is moved up and down, safety is ensured. The channel member 4 can be moved up and down one at a time or two facing each other.

In response to the lifting and lowering of the channel member 4 as described above, the suspension sphere 6 is operated as shown in FIG.

That is, when the channel member 4 ascends, the hook 52 on its outer side approaches the edge of the slab at a predetermined distance, but its upper end interferes with the free end of the hanger 72 and pushes it up. The hanger 72 which is passed and is pushed up is allowed to stand only within a predetermined angle by the cover 11 and is released from the interference by the hook 52 so as to be restored horizontally again by the action of its own stopper ( 8) is supported by. When the hook 52 is placed in the passed position out of the range that interferes with the hanger 72, the dustproof frame 4 is lowered again slightly so that the hook 52 is suspended on the hanger 10. Go installation is complete. During the process, a part of the channel member 4 enters between the guide rollers 22 and starts to be guided. At this time, the base body 62 is driven within the range defined by the bolt hole 64 on the long ellipse. The position error existing between the member 4 is eliminated.

In the above-described embodiment, the guide roller 22 of the anti-vibration frame 2 is illustrated as a configuration in which the guide roller 22 is directly guided to the channel member 4. The guide roller 26 may be added to allow the guide roller 22 to be guided to a more stable structure. In this case, the guiders 26 may be symmetrically attached to the inner side of the channel member 4 as shown in FIG. 7 or welded to the outside as shown in FIG. 8.

As described above, in the construction of a high-rise building, the apparatus of the present invention installs and installs a dustproof frame to the channel member at each floor to completely block the outside of the construction frame during construction of a building using the 'I' steel. In addition, the channel member is guided up and down riding a fixed suspension ball attached to the slab edge of each floor, and can be easily installed in the field because it is fixed at the fixed position, standardization of the dustproof frame and the channel member is easy Load carrying also has the advantage of being convenient.
