2. Description of the Related Art Generally, as shown in FIG. 8, a building 1 to be newly built is provided with a scaffolding 2 for construction along the outside thereof, and an operator S rides on the scaffolding 2 for construction. It is like this. The building scaffolding 2 is constructed such that the building scaffolding 2 is sequentially assembled upward as the working height of the building 1 increases. Conventionally, when the worker S pulls up the building material 3 on the ground from the upper end of the building scaffold 2 to the upper end of the building scaffold 2, the worker S hangs the rope downward. Another worker S on the ground attaches the building material 3 to the lower end of the rope and then pulls it up. However, since the weight of the building material 3 acts on the lifting operator S as a proper burden, this lifting operation is difficult and time-consuming, and the lifting operator S and the ground are present. The worker S may be in danger. Therefore,
A building lifting device 5 having a hoist body 4 as shown in FIG. 7 is used.

The construction lifting device 5 has a structure in which a pair of left and right guide rails 6 and 6 are connected to an upper end portion 211 of a vertical pipe member 21 constituting the scaffolding 2 for construction and arranged along the building 1. In addition, rolling wheels (not shown) rotatably attached to the left and right sides of the crane platform 7 are arranged so that they can be guided, and the hoist body 4 is mounted on the crane platform 7. According to this construction lifting device 5, a crane platform 7
Crane arm 4 provided with hoist body 4 placed on
After the ground worker S attaches the building material 3 to the lower end of the suspending wire 42 hung from 4, the worker S or the like on the scaffolding 2 for building remotely operates the lifting device 5 for building or the like. The building material 3 was operated to be pulled up to the upper end of the building scaffold 2.

[0004]

However, guide travel along the guide rails 6 and 6 by the rolling wheels (not shown) provided on the left and right sides of the crane platform 7 of the above-mentioned construction lifting device 5. Therefore, when the direction is changed by 90 degrees at the corner 2a of the scaffold 2 for construction arranged at the corner 1a of the building 1, the crane platform 7 is temporarily lifted and the direction is changed. However, the work of changing the direction of the crane platform 7 is troublesome and the workability is extremely poor. An object of the present invention is to solve the above conventional problems.

That is, the crane platform on which the hoist body is placed can be easily turned at the corner of the building scaffolding located at the corner of the building without lifting the crane platform. (EN) It is an object to provide a hoisting device for construction which has a very simple structure for changing its direction and which can be produced easily and at low cost.

[0006]

In order to achieve the above object, the present invention provides a pair of left and right guide rails arranged along the building at the upper end of a vertical pipe material constituting a scaffold for construction, and a crane. In a building lifting device in which rolling wheels rotatably installed on the left and right sides of a platform are rotatably mounted on a guide and a hoist body is placed on this crane platform, A rotation support frame is attached to the upper end of the scaffold, and the corner guide rails are horizontally rotatably supported by the rotation support frame via a rotation support tool such as a bearing. Further, a rotation support frame that supports the corner guide rails is attached to the upper end of the vertical pipe of the building scaffold so as to be adjustable in vertical height position via height adjusting means.

[0007]

[Operation] The crane platform on which the hoist body is placed is guided and guided by the guide rails attached to the scaffolding for construction arranged along one surface of the building, and at the corners of the building. Guide travel to the position of the corner guide rail supported horizontally rotatably via a rotation support tool such as a bearing on a rotation support frame installed at the upper end of the scaffold for construction,
When the rolling wheels are arranged on these corner guide rails, when the corner guide rails are rotated in the horizontal direction around a rotation support tool such as a bearing, the corner guide rails are It is connected to a guide rail attached to a construction scaffolding arranged along the other surface. As a result, the crane platform on which the hoist body is placed can be easily turned without lifting.
Further, in a structure in which a rotary support frame for supporting the corner guide rails is attached to the upper end of the vertical pipe of the building scaffold so as to be adjustable in vertical height position via height adjusting means. By adjusting the vertical height of the rotary support frame with, the vertical height of the corner guide rails supported by this rotary support frame can be adjusted to be the same as the guide rails on both sides. .. As a result, there is no step between the corner guide rails and the guide rails on both sides, so that the guide wheels of the rolling wheels attached to the crane platform can smoothly run.
