Embodiments for Carrying Out the Invention

[0015] (Embodiment 1) Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. As shown in FIGS. 1(A) and 1(B), the panel hanger 1 of the embodiment grips the upper end portion of the outer wall panel 5 which is a sandwich panel having a first surface 51 and a second surface 52 facing away from the first surface 51 in the thickness direction.

[0016] The first surface 51 is a surface located on the outdoor side and is made of a metal plate. The second surface 52 is a surface located on the indoor side and is made of a metal plate. A heat insulating material 53 is disposed between the first surface 51 and the second surface 52.

[0017] Also, on the upper end side on the side of the first surface 51 of the outer wall panel 5, a first surface side convex portion 511 that is long in the panel width direction and protrudes upward is formed. The first surface side convex portion 511 is produced by bending the metal plate that is the first surface 51. Further, in the outer wall panel 5, a concave surface 51a that is located below the first surface side convex portion 511 and is recessed inward in the thickness direction of the outer wall panel 5 is formed. Also, in the first surface side convex portion 511, an outer protruding region 51b that protrudes outward in the thickness direction of the outer wall panel 5 more than the concave surface 51a is formed.

[0018] Also, on the upper end side on the side of the second surface 52 of the outer wall panel 5, a second surface side convex portion 521 that is long in the panel width direction and protrudes upward is formed. In this example, the second surface side convex portion 521 is located at a position that enters more inside the panel than the second surface 52. The second surface side convex portion 521 is produced by bending the metal plate that is the second surface 52.

[0019] Then, when two outer wall panels 5 are arranged vertically, the first surface side convex portion 511 and the second surface side convex portion 521 of the outer wall panel 5 located in the lower stage are respectively fitted into two recesses formed on the lower end surface of the outer wall panel 5 located in the upper stage, and the upper and lower outer wall panels 5 are combined so as not to be displaced in the out-of-plane direction from each other.

[0020] As shown in FIG. 2, the panel hanger 1 includes a first engaging member 11, a second engaging member 12, a fixing portion 13, and an arm portion 14.

[0021] The first engaging member 11 has a through-guide portion 11a that penetrates in the thickness direction of the outer wall panel 5 within the first engaging member 11, and an insertion portion 12a described later can be inserted into this through-guide portion 11a. Further, in the first engaging member 11, one first pin insertion hole portion 110 is formed so as to cross the above-described through-guide portion 11a in the panel width direction of the outer wall panel 5. Furthermore, the first engaging member 11 has an engaging concave portion 11b that engages with the lower surface portion and the upper surface portion of the outer protruding region 51b of the first surface side convex portion 511 in a state where the insertion portion 12a is inserted into the through-guide portion 11a. It is desirable that the play when the engaging concave portion 11b engages with the outer protruding region 51b is minimized as much as possible.

[0022] The second engaging member 12 has an insertion portion 12a that extends in the thickness direction of the outer wall panel 5. The longitudinal cross-section of this insertion portion 12a is a vertically long rectangle, and the longitudinal cross-section of the above-described through-guide portion 11a into which the insertion portion 12a is inserted is a vertically long rectangular space. It is desirable that the play when the insertion portion 12a and the through-guide portion 11a are fitted is minimized as much as possible. And in the insertion portion 12a, a plurality of second pin insertion hole portions 120 are formed at a predetermined interval in the thickness direction of the outer wall panel 5 so as to cross the insertion portion 12a in the panel width direction of the outer wall panel 5.

[0023] Further, a facing portion 12b is formed on the second engaging member 12. The facing portion 12b engages in a facing state with the standing upper surface 52a located on the side of the second surface 52. The thickness of the facing portion 12b is approximately the same as the dimension of the second surface side convex portion 521 that enters the panel inner side, and the second engaging member 12 has an end portion that is substantially flush with the second surface 52 in a state of being mounted on the upper end side of the outer wall panel 5.

[0024] The fixing part 13 fixes the first engaging member 11 and the second engaging member 12 to each other in a state where the first surface side convex portion 511 and the second surface side convex portion 521 of the outer wall panel 5 are gripped by the first engaging member 11 and the second engaging member 12. The above-mentioned fixing position in the fixing part 13 is, for example, a position outside the outer wall panel 5 in the thickness direction rather than the outer protruding region 51b. Further, in this embodiment, the fixing part 13 is composed of an insertion member (pin member, bolt and nut, etc.) inserted into a communication location with either the first pin insertion hole part 110 formed in the first engaging member 11 or the plurality of second pin insertion hole parts 120 formed in the second engaging member 12 in the thickness direction of the outer wall panel 5.

[0025] The arm part 14 has a hanging position 14a above the upper end of the outer wall panel 5 where a hanging member (lifting hook, wire, etc.) on the crane side is hung. The hanging position 14a is, for example, a circular through hole penetrating the arm part 14 in the horizontal direction. Further, a plurality of hanging positions 14a are provided, and for a plurality of types of outer wall panels 5 with different thicknesses, any one of the hanging positions 14a can be selected so that the vertical line of the position where the above-mentioned hanging member on the crane side is hung passes through the inside of the outer wall panel 5 (panel center of gravity) as much as possible. In this embodiment, the arm part 14 is formed in the second engaging member 12 and extends upward from the side where the second surface 52 of this second engaging member 12 is located above the outer wall panel 5.

[0026] In the above configuration, as shown in FIG. 3, when attaching the panel hanger 1 to the outer wall panel 5, the opposing portion 12b of the second engaging member 12 is engaged with the standing surface 52a, and the first engaging member 11 with the insertion portion 12a inserted is brought closer to the outer wall panel 5 side, and the engaging recess 11b is engaged with the lower surface portion and the upper surface portion of the outer protruding region 51b. By this engagement, the first engaging member 11 and the second engaging member 12 grip the first surface side convex portion 511 and the second surface side convex portion 521 of the outer wall panel 5. In this gripped state, depending on the thickness of the outer wall panel 5 (the distance between the first surface side convex portion 511 and the second surface side convex portion 521), one of the first pin insertion hole portions 110 and one of the second pin insertion hole portions 120 communicate with each other, and by inserting an insertion member, which is the fixing portion 13, into this communication location, the above-described gripped state by the first engaging member 11 and the second engaging member 12 is fixed.

[0027] Then, in a state where the gripping state is fixed by the fixing portion 13, when the lifting member on the hoist side is hung on the hanging position 14a of the arm portion 14 and the outer wall panel 5 is lifted, this lifting force is applied to the lower surface side of the outer protruding region 51b from the engaging recess 11b. And even if the first engaging member 11 tries to rotate counterclockwise around the fixing portion 13 in FIG. 1, the engaging recess 11b hits against the lower surface side of the outer protruding region 51b so as to bite into the base portion of the lower surface side, and this rotation is blocked. On the other hand, even if the first engaging member 11 tries to rotate clockwise around the fixing portion 13 in FIG. 1, the engaging recess 11b hits against the upper surface side of the outer protruding region 51b so as to press the upper surface side, and this rotation is also blocked.

[0028] Also, even if the outer wall panel 5 tries to rotate clockwise around the first surface side convex portion 511 in FIG. 1, the standing surface 52a of the second surface side convex portion 521 hits against the opposing portion 12b of the second engaging member 12, so the above rotation of the outer wall panel 5 is blocked, and the upper end portion of the outer wall panel 5 does not come off from the panel hanger 1.

[0029] And thus, in the panel hanger 1, a simple structure including the first engaging member 11, the second engaging member 12, the fixing portion 13, and the arm portion 14 is realized. Further, the first engaging member 11 and the second engaging member 12 can grip the first surface side convex portion 511 and the second surface side convex portion 521 from the outside of the outer wall panel 5 and then fix and lift the first engaging member 11 and the second engaging member 12 to each other, so that the attachability to the outer wall panel 5 is also excellent.

[0030] Also, when the fixing portion 13 is composed of an insertion member inserted into the communication portion between the first pin insertion hole portion 110 formed in the first engaging member 11 and the plurality of second pin insertion hole portions 120 formed in the second engaging member 12, by inserting this insertion member into the above communication portion, it becomes possible to quickly fix the gripping state of the outer wall panel 5.

[0031] And when the plurality of second pin insertion hole portions 120 are formed in the thickness direction of the outer wall panel 5 corresponding to a plurality of types of outer wall panels 5 having different thicknesses, as shown in FIGS. 4(A), 4(B), 5(A), and 5(B), it becomes possible to handle a plurality of types of outer wall panels 5 having different thicknesses with one panel hanger 1. In these figures, the mounting location of the fixing portion 13 is indicated by circular hatching.

[0032] Also, for a plurality of types of outer wall panels 5 having different thicknesses, when a plurality of hanging positions 14a are provided in the thickness direction of the outer wall panel 5 such that the vertical line of the hanging location of the hanging member on the hoist side passes through the inside of the outer wall panel 5 (panel center of gravity), it becomes possible to lift the outer wall panel 5 in a vertical posture as much as possible. In FIGS. 4 and the like, a virtual line circle is appended to the used hanging position 14a.

[0033] FIG. 6(A) illustrates the operation of attaching the panel hoist 1 to the upper end portion of the outermost wall panel 5 at the uppermost position among the flat-stacked outermost wall panels 5 and raising the outermost wall panel 5 at the uppermost position using a hoist. As shown in FIG. 6(B), for example, the panel hoist 1 is attached to two locations on the upper end side of the outermost wall panel 5, and the outermost wall panel 5 can be directly lifted by a two-point wire. However, it is not limited to this, and the outermost wall panel 5 can also be lifted using a balance.

[0034] (Embodiment 2) Hereinafter, other embodiments of the present invention will be described with reference to the accompanying drawings. Note that the same reference numerals are assigned to the same components as those in Embodiment 1, and the description thereof will be omitted.

[0035] In Embodiment 1, the arm portion 14 was provided on the second engaging member 12. However, in the panel hoist 1 of this Embodiment 2, as shown in FIGS. 7(A) and 7(B), the arm portion 14 is provided on the first engaging member 11, and this arm portion 14 extends from the upper part of the first engaging member 11 to the upper side of the outermost wall panel 5.

[0036] Also in the panel hoist 1 of this Embodiment 2, as shown in FIG. 8, with the opposing portion 12b of the second engaging member 12 engaged with the standing surface 52a, the first engaging member 11 with the insertion portion 12a inserted is brought closer to the outermost wall panel 5 side, and the engaging recess 11b is engaged with the lower surface portion and the upper surface portion of the outer protruding region 51b. By this engagement, the first surface side convex portion 511 and the second surface side convex portion 521 of the outermost wall panel 5 are gripped by the first engaging member 11 and the second engaging member 12. In this gripped state, depending on the thickness of the outermost wall panel 5, the first pin insertion hole portion 110 communicates with one of the second pin insertion hole portions 120, and by inserting the insertion member, which is the fixing portion 13, at this communication location, the above-described gripped state by the first engaging member 11 and the second engaging member 12 is fixed.

[0037] Also in the panel hanger 1 of the second embodiment, the fixing portion 13 is composed of an insertion member inserted into a communication portion between the first pin insertion hole portion 110 formed in the first engaging member 11 and a plurality of second pin insertion hole portions 120 formed in the second engaging member 12. As shown in FIG. 9, by quickly selecting any one of the plurality of second pin insertion hole portions 120 formed in the thickness direction of the outer wall panel 5 among a plurality of types of outer wall panels 5 having different thicknesses and inserting the insertion member, it is possible to quickly fix the gripping state of the outer wall panel 5.

[0038] In these embodiments, it is possible to handle a plurality of types of outer wall panels 5 having different thicknesses with one panel hanger 1. However, the present invention is not limited to this. As shown in FIG. 10, a panel hanger 1 dedicated to an outer wall panel 5 having a predetermined thickness can also be used. Further, the second engaging member 12 of such a dedicated panel hanger 1 may have a fitting portion 12c that fits between the convex portion 511 on the first surface side and the convex portion 521 on the second surface side of the outer wall panel 5. According to this, when the outer wall panel 5 is lifted, the fitting portion 12c can prevent the convex portion 511 on the first surface side and the convex portion 521 on the second surface side from deforming in a direction approaching each other, and prevent a decrease in the gripping force on the upper end portion of the outer wall panel 5.

[0039] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made within the same scope or an equivalent scope as the present invention with respect to the illustrated embodiments.
