[0012] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a front view showing a portable wooden house according to one embodiment of the present invention in a lifted state. Fig. 2 is a side view of the portable wooden house shown in Fig. 1. The portable wooden house of this embodiment is a house such as a prefabricated house or a modular house that can be suitably used as a detached room or the like, and is made of wood to reduce weight and cost.
[0013] As shown in Figures 1 and 2, the portable wooden house 1 comprises a house main body 10 and a lifting device 20 attached to the house main body 10. Using the lifting device 20, the house main body 10 can be lifted in a pre-assembled state and transported by truck or the like.
[0014] The house main body 10 is constructed by covering the sides of a wooden structure made of pillars and beams with an exterior wall 11. The lifting tools 20 are detachably provided at multiple locations on the exterior wall 11 of the house main body 10. In this embodiment, two lifting tools 20 are detachably attached at the same height on each side of the house main body 10 in the longitudinal direction.
[0015] The house body 10 can be hoisted by engaging a linear hoisting member 30 such as a belt or wire with the hoisting tool 20. The hoisting member 30 is supported at both ends of a square cylindrical support pipe 31, and the support pipe 31 is hoisted by a crane 33 via a support wire 32.
[0016] Fig. 3 is a cross-sectional view of a main part of the portable wooden house 1, showing a state in which the lifting tool 20 is attached to the house main body 10. As shown in Fig. 3, the lifting tool 20 has a rectangular flange portion 21 that abuts against the surface of the exterior wall 11, a main body portion 22 that protrudes horizontally from the surface of the flange portion 21, and a plurality of bolt portions 24 that protrude horizontally from the back surface of the flange portion 21.
[0017] Fig. 4 is a side view of the lifting tool 20 shown in Fig. 3 as viewed in the direction of the arrow A. As shown in Figs. 3 and 4, the main body 22 is formed in the shape of an H-beam with a web between a horizontal plate-like upper flange and a lower flange, and has high bending rigidity. A ring-shaped engagement part 23 with which the hanging material 30 engages is provided on the upper surface of the tip side of the protruding direction of the main body 22. The protruding length of the main body 22 is not particularly limited, but in order to facilitate lifting using the engagement part 23, it is preferable to form the main body 22 so that the engagement part 23 is positioned slightly outward from the eaves of the house main body 10.
[0018] The bolt portions 24 are disposed at four locations corresponding to the vertices of the rectangular shape, and the flange portion 21 can be fastened to the outer wall 11 by screwing nuts 25. It is sufficient that a plurality of bolt portions 24 are disposed at least above and below the flange portion 21, and the number of bolt portions 24 is not particularly limited.
[0019] The exterior wall 11 of the house body 10 is constructed by covering the outer surface of an exterior wall material 12 made of structural plywood or the like with an exterior material 13 made of calcium silicate board (calcium silicate board) or the like. Wooden beams 15 that form the outermost part of the structure of the house body 10 are arranged inside the exterior wall 11, and interior material 14 made of gypsum board or the like is arranged inside the beams 15. Between the exterior wall material 12 and the interior material 14, wooden horizontal bars 16 and vertical bars 17 are arranged.
[0020] Of the four bolt portions 24 provided on the lifting tool 20, the two bolt portions 24 arranged on the upper side of the flange portion 21 penetrate the exterior wall 11, the beam 15, and the interior material 14, and protrude to the rear surface side of the interior material 14. On the other hand, the two bolt portions 24 arranged on the lower side of the flange portion 21 penetrate the exterior wall 11, the cross rail 16, and the interior material 14, and protrude to the rear surface side of the interior material 14.
[0021] Fig. 5 is a view of the beam 15, horizontal beam 16, and vertical beam 17 shown in Fig. 3 as viewed in the direction of arrow B. A plurality of vertical beams 17 are arranged above and below the beam 15 with a gap between them on the left and right. Meanwhile, the horizontal beam 16 is arranged below the portion where the upper two bolt portions 24 are inserted into the beam 15, and both ends of the horizontal beam 16 are supported by the vertical beams 17, 17, through which the lower two bolt portions 24 are inserted.
[0022] 6, a receiving plate 26 having through holes 26a at positions corresponding to the four bolt portions 24 protruding from the rear surface side of the interior material 14 is attached, and a nut 25 is screwed through a washer. The cross beam 16 is not essential to the present invention, and may have a different configuration from this embodiment as long as at least the upper bolt portion 24 penetrates the beam 15. However, by providing the cross beam 16, it is possible to reliably prevent the interior material 14 from being dented when the lower bolt portion 24 is fastened by screwing the nut 25.
[0023] When the portable wooden house 1 having the above configuration is lifted by engaging a hanging material with the engagement portion 23 of the lifting tool 20 shown in Fig. 3, the beam 15 through which the upper bolt portion 24 is inserted is subjected to a large compressive load caused by the flexural deformation of the main body portion 22, while the cross rail 16 through which the lower bolt portion 24 is inserted is not subjected to a compressive load, so that the house main body 10 to be lifted can be lifted reliably without being damaged. After the house main body 10 is lowered and set up at the destination, the lifting tool 20 is removed and the insertion holes of the bolt portions 24 are filled with a sealant and colored to seal and make the traces of the removal of the lifting tool 20 less noticeable.
[0024] In the portable wooden house 1 of this embodiment, the lifting device 20 is attached so that it protrudes laterally from the exterior wall 11, utilizing the high compressive strength beams that the house main body 10 originally has as a structural component. This makes it possible to quickly and easily install the lifting device 20, lift the house main body 10, and install the house main body 10, while also preventing the infiltration of rainwater, etc. after the lifting device 20 is removed.
