[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof member mounting device for efficiently mounting a roof member on a construction site.

[0002]

2. Description of the Related Art Conventionally, roof members such as panels have generally been mounted one by one using a crane. Further, at the roof installation section, a crane is operated from the ground according to an instruction from a worker who is on the roof to lower the member to a predetermined position.

[0003]

However, it is inefficient to stack the roof members one by one as in the conventional case, and it is not possible to lower the members from the ground to a predetermined position on the roof only by operating the crane. It was a very difficult task. The present invention has been made to solve this problem, and an object of the present invention is to provide a roof member mounting device capable of collectively mounting roof members and simultaneously lowering the mounted members to a predetermined position easily.

According to a first aspect of the invention, a suspension frame is constructed by connecting suspension beams having a mounting portion for attaching a wire from a crane with a gap therebetween, and A plurality of electric chain blocks are attached to both sides, and a control device for remotely controlling the electric chain block and a power supply for the electric chain block and the control device are mounted on a suspension frame.

In the device of the second aspect of the invention, a suspension frame is constructed by connecting suspension beams having a wire mounting portion from a crane at intervals, and a plurality of fixing beams are provided on one side of each of the opposing suspension beams. Along with mounting the electric chain block, a trolley guide rail is installed on the suspension frame along the suspension beam to arrange multiple electric chain blocks with trolleys, and one side of the roof member is fixed with the electric chain block for fixing, and the electric chain block with trolleys. It is designed to hold one side facing each other.

[0006]

According to the first aspect of the present invention, after mounting the hoisting device to the crane through the wire mounting portion, the four electric chain blocks corresponding to the ends of the suspension beams hold the four points on the outer edge of the roof member. Accordingly, it is possible to simultaneously mount as many roof members as the number of electric chain blocks attached to each end of the suspension beam by the crane. Further, in the roof installation section, an operator can control each electric chain block while wirelessly observing the roof member and the installation position to accurately lower the roof member to a predetermined position.

According to the second aspect of the invention, the roof member is vertically hung by the electric chain block for fixing, whereby a plurality of roof members are attached to the main hoisting device and the hoisting device and the roofing device are simultaneously hoisted up to the roof installation portion. be able to.
In addition, at the roof installation section, workers can
Move the electric chain block with trolley along the guide rails to make the roof member almost horizontal and hold it at 4 points on the outer edge, and control each electric chain block while watching the roof member and the installation position to move the roof member. Can be accurately lowered into place.
