In the wooden panel construction method in which each building panel is assembled to form a building, a plurality of unit panels are connected to construct a floor, a wall and a roof.

In this case, if all the building panels on the floor, walls, and roof are assembled on site, there is a problem that the construction is troublesome and the construction period is prolonged. In addition, the skill of the operator is required to improve the assembly accuracy.

Therefore, by preliminarily assembling a plurality of unit panels at a factory, transporting the formed building panel to the site, and assembling the preassembled building panel, the work at the site is simplified. Production efficiency is being improved by shortening the construction period and improving accuracy.

However, when the building panel transported from the factory is hoisted by a crane or the like on site, the following problems occur.

For example, in the case of a roof panel or a floor panel, it can be hoisted substantially horizontally in advance so that installation can be completed by lowering the building panel hoisted by a crane or the like as it is. This will be described with reference to FIG. 5 by taking the case of a roof panel as an example. The roof panel 100 is formed by connecting a plurality of unit panels 120 in a plane direction. Attach 160. And this hanging hardware 1
A hanging jig 170 is attached to 60, and a hanging metal fitting 164 included in the hanging jig 170 is hooked on the eaves side end of the roof panel 100, and is lifted in an oblique horizontal state by a crane or the like via the hanging jig 170. To be

In this case, since the roof panel 100 is long in the vertical direction, the load is concentrated near the central portion in the longitudinal direction. Therefore, the unit panel 1 located near the center
It was necessary to reinforce the roof panel 100 in order to prevent the joint portion 150 of the 20 from being broken.

In order to improve the mechanical strength of a building panel formed by joining a plurality of unit panels,

It is attached to the front side of the unit panel so that the surface of the vertical core member 30 and the surface of the crosspiece member 44 are flush with each other.

The crosspiece 44 serves as a mounting portion when the face material 50 is attached to the large roof panel.
It also has the function of preventing the warp.

The large-sized roof panel 10 is formed by joining the unit panels 20 having the above-described structure in the longitudinal side direction, that is, in the direction of the vertical core member 30, by bringing the joint side surfaces of the joint-side lateral core members 42 into contact with each other. However, since the unit panels 20a and 20b having the same configuration are joined as described above, the vertical core members 30 of the unit panels 20a and 20b are linearly continuous and the vertical core members of the large roof panel 10 are connected.

Therefore, even if it is a fairly large-scale building panel in which a plurality of unit panels are joined, the mechanical strength can be improved, and it is possible to reliably prevent the middle bending during the lifting movement only by the connecting reinforcing plate. .

Further, the workability is good because the connecting reinforcing plate does not interfere with the transportation even if it does not require time-consuming processing work such as a countersink. Furthermore, it can also be applied to large-scale building panels with so-called finishing materials, which are shipped to the site after finishing materials are installed in the factory.

According to the second aspect of the present invention, a plurality of connecting reinforcing plates are attached to the respective side surfaces of the outer frame vertical core member and the middle vertical core member constituting the unit panel, so that a machine for a large panel for construction is constructed.
