Description

[Detailed description of the invention] The present invention relates to an apparatus for lifting external wall materials.

Conventionally, when installing exterior wall materials on the exterior wall of a building using a hoisting machine such as a truck crane, the eaves and handrails provided above each window of the building, or the eaves provided on the top floor, were placed on the exterior wall surface. Because it protrudes further outward than the eaves, it becomes an obstacle to installing the exterior wall materials.After lifting the exterior wall materials with only the protruding part of the eaves released from the wall surface, workers may use scaffolding to push the exterior wall materials up to the wall surface, or use scaffolding. A frame to support the weight of the exterior wall material or a crane had to be installed between it and the wall to install the exterior wall material on the wall, which required a lot of construction costs and construction time.

The present invention proposes a lifting device for exterior wall materials that solves the above-mentioned drawbacks. Next, embodiments of the present invention will be described based on the drawings. FIG. 1 shows a fixed type device of the main body arm of the present invention, and FIG. 2 shows a telescopic arm of the main body arm. In FIG. 1, a connecting portion 3 of a hanging wire 2 is provided at the tip of a vertical portion of an L-shaped main body arm 1, and a hanging arm 4 is connected to a horizontal connecting shaft 6 at the tip of a horizontal portion.
At the other end of the mounting bracket 5, a hanging arm 4 having hanging brackets a for the exterior wall material 7 fixed to the lower portions of both ends is fitted and suspended from a vertical shaft 9 so as to be horizontally rotatable. Furthermore, the connecting plate 10, which is clamped and fixed to the L-shaped intersection of the main body arm 1, counteracts the rotation moment caused by the main body arm 1 around the connecting part 3 of the hanging wire 2 due to the load of the outer wall material 7. A counter arm 13 is supported by a rotating shaft 17 provided at the bottom and has a counter weight 12 of a predetermined weight fixed to the tip thereof, and is mounted so as to be movable up and down.
Attach the winch 15 to the upper part of the vertical part of the main body arm 1,
By attaching the chain mounting bracket 14 to a predetermined position on the counter arm 13 and connecting it with the chain 16, when the hanging arm 4 is used to lift the exterior wall material 7, the counter arm 13 is rotated by operating the winch 16. 1
The balance of the rotational moment of the main body arm 1 is maintained by the rotation moment of the exterior wall material 7 and the rotation moment in the opposite direction due to the counterweight 12 while moving the exterior wall material 7 up and down around the main body arm 1, and the exterior wall material 7 is lifted to a predetermined position on the wall surface by the hanging wire 2. After hoisting it along the wall, rotate the horizontal part and attach it to the wall.

Fig. 2 shows that the vertical part 19 and the horizontal part 20 of the L-shaped main body arm are separated, and the L-shaped intersection part is connected by a hollow box-shaped connecting member 17, so that the horizontal part 20 can be expanded and contracted. That is. After the horizontal part 20 is expanded and contracted to a predetermined position by the arm fixing pin 18, the connecting member 17 and the horizontal part 20 are fixed together to further improve workability.

As mentioned above, this invention allows external wall materials to be easily lifted up, rotated, and installed on the wall surface at a predetermined position, regardless of the eaves or other protruding parts of a building. Exterior wall materials can be hoisted horizontally while maintaining balance by operating up and down.
