2. Description of the Related Art In general, a wooden panel having a rectangular panel formed of a crosspiece and having a panel material attached to at least one surface thereof is prepared in advance, and the wooden panel is assembled at a building site. There is known a panel construction method that saves labor on site by constructing floors, walls, roofs, and the like. In this panel construction method, a plurality of wooden panels are assembled and connected in advance to form a large connection panel, and the large connection panel is installed on a building site to construct a building. It is well known that there is a panel construction method that saves labor.

In order to construct a wall of a house by using such a large connecting panel, for example, it is necessary to install the large connecting panel in an upright state in a construction site. As the number of workers increases, it becomes more difficult for workers to perform the work manually. Therefore, in the case of constructing a wall with the large connecting panel, basically, the large connecting panel is lifted upright by a lifting device such as a crane, and the large connecting panel is installed on a part of the wall to be constructed. I have.

Meanwhile, as a structure of a large connecting panel lifted by the crane, for example, Japanese Patent Application Laid-Open No.
There is a publication of US Pat. The large-sized connecting panel disclosed in this publication is lifted by using a so-called panel hanger which is a hanging tool for towing a crane. A panel hanger disclosed in Japanese Patent Application Laid-Open No. 9-209537 is composed of a support rod arranged horizontally when pulled up, a support wire for hooking the support rod on a wire hook, and left and right ends of the support rod. And two hanging chains, each of which is suspended from the chain, and a ten-piece fitting attached to the tip of each of the hanging chains. The ten-hand metal fitting has a rod connected to the lifting chain and arranged vertically, and a locking piece that can be freely protruded and retracted left and right from the tip of the rod by a lever.

[0005] A vertical insertion hole and a locking hole perpendicular to the insertion hole are formed in the bar member along the vertical direction of the large-sized connection panel to be suspended. A tenth metal fitting is inserted, and a locking piece of the tenth metal fitting is made to protrude and inserted into the locking hole. As a result, the ten-piece fitting is engaged with the crosspieces along the longitudinal direction of the large panel, and the large connecting panel can be lifted.

[0006]

However, according to the technique disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 9-209537, an insertion hole and a locking hole are formed in a large connecting panel to be suspended in order to lock a ten-piece metal fitting. A forming process is required. Further, when locking the locking piece of the ten-handed metal fitting into the locking hole formed in the panel, the state cannot be seen from the outside, so that the locking piece is engaged with the locking hole. Since the panel is lifted after confirming whether or not it has been stopped, the work requires some trouble. Further, since the insertion hole and the locking hole are provided in the panel, the strength of the entire panel does not change, but a slight decrease in the strength of the insertion hole and the locking hole cannot be denied.

As a method of lifting the large connecting panel and installing it at a predetermined position, for example, a locking hole in which a locking piece of a ten-piece fitting is locked at the upper end on both sides of the large connecting panel serving as a wall. There is a method of attaching a suspension plate having a slab, and lifting the connection panel in a well-balanced manner via the suspension plate. However, according to this method, when joining the side end surfaces of the large-sized connected panels that are lifted to form an outgoing corner or an inset corner, the hanging plate is located at the outgoing corner or the ingoing corner, and the large-sized connected panels are connected to each other. And it must be displaced to change its position, which takes time and effort.

[0008] The present invention has been made in view of the above circumstances, and an object of the present invention is to easily lift and install an object to be suspended, for example, a panel constituting a building regardless of its size.
