Hereinafter, an embodiment of the present invention will be described based on the attached drawings.
As shown in FIG. 1, the outer wall panel 500 (5) has, for example, a structure in which a plurality of horizontally long outer wall surface materials 51 are vertically arranged and mutually connected by a base material 52. In the example shown in FIG. 1, a vertical trunk edge 52 a is provided as the base material 52.

  The outer wall surface material 51 is, for example, a metal sandwich panel in which a heat insulating material 51a is sandwiched between steel plates 51b and 51c as shown in FIGS. 2 (A) and 2 (B). When the two outer wall surface members 51 are arranged vertically, in the two concave portions 51 d long in the lateral width direction formed on the upper end surface of the outer wall surface member 51 positioned at the lower level, the outer wall surface material 51 positioned at the upper tier When the two convex portions 51e long in the lateral width direction formed on the lower end face are fitted, the upper and lower outer wall surface members 51 are combined so as not to be displaced in the out-of-plane direction.

  As shown in FIG. 3, by using the ground assembly frame 1, the outer wall panel 500 (5) is attached with the outer wall panel 500 (5) in which the plurality of outer wall surface members 51 are vertically arranged and connected by the base material 52. It can be assembled at a different place from the wall mounting point of the frame 7 of the building being constructed.

  The ground frame 1 includes a support 11A positioned on the side of the outer wall 51, a back support 11B disposed on the rear 51 of the outer wall 51, and the support 11A. It is provided with three beam parts 12 bridged respectively on the lower side, middle side and upper side of 11B, and a pillar 11C supporting them.

  For example, the lower side of the column 11A is fixed on the upper surface of the lower beam 12, and the central and upper sides of the column 11A are on the front side of the middle and upper beams 12. Each is fixed via a spacer. The middle and upper beam portions 12 are provided on the rear surface side of the longitudinal trunk 52a. Further, the lower end of the back side support column 11B is fixed on the upper surface of the lower side beam section 12, and the central part and the upper part of the back side support column 11B are on the front side of the middle side and upper side beam 12 It is fixed.

  The base material holder 2 holding the vertical barrel edge 52a is fixed on the beam portion 12 located in the upper stage and the beam portion 12 located in the middle stage. The beam portion 12 located at the lower side is provided with a positioning convex portion into which the vertical barrel edge 52a is inserted or a positioning plate portion with which a side surface of the vertical barrel edge 52a is abutted.

  After setting the longitudinal trunk edge 52a, the operator sets the outer wall surface material 51, screws a screw or the like to the upper end portion side of the set outer wall surface material 51, and sets the outer wall surface material 51 first. It fixes to the said vertical trunk edge 52a. By repeating this operation, the outer wall panel 500 (5) is manufactured.

  Moreover, as shown in FIG. 4, the outer wall panel 5 which has an opening frame part for attaching the opening installation 4 can be assembled using the said ground mounting frame 1. As shown in FIG. However, in this example, the opening facility 4 is not attached to the outer wall panel 5 on the ground mounting frame 1. After the outer wall panel 5 having the opening frame is assembled, the outer wall panel 5 is removed from the ground mounting frame 1 and lifted by a crane or the like, and as shown in FIG. 7. Attach to the floor beam 71, the wind resistant beam 72, the floor, etc. 7 by using an L angle, a mounting bolt, a fixing bolt or the like.

  Examples of the opening facility 4 include an aluminum sash, a glari, a ventilation fan, a steel door, and the like. In order to fix the opening installation 4 to the outer wall panel 5, horizontal trunk edges 54 are provided above and below the opening installation 4 so as to cross between the left and right vertical trunk edges closest to the opening installation 4. That is, in this example, the outer wall panel 5 has a structure in which the horizontal trunk 54 is provided above and below as an opening frame in a region including a portion where the opening is formed.

  After the outer wall panel 5 is attached to the frame 7 of the building, the opening facility 4 is attached from the indoor side. As an example, as shown in FIGS. 6 (A), (B), (C) and FIG. 7, in each of the inner corners formed by the above-mentioned lateral trunk edge 54 and the longitudinal trunk edge 52a where this end face abuts. For example, a so-called cat hardware 55 having an L shape is disposed, and the horizontal trunk 54 and the vertical trunk 52a are fixed in a frame shape to each other by driving a bolt or the like.

  The opening facility 4 is fixed to, for example, a rectangular base frame 41 made of steel. The base frame 41 is composed of horizontal frame members 41a arranged vertically and vertical frame members 41b arranged horizontally, which are also mutually fixed by, for example, a cat metal. Then, for example, as shown in FIG. 6 (A), the right vertical trunk edge 52c is fixed to the upper and lower horizontal trunk edges 54 by the cat hardware 56. On the other hand, the left vertical waist 52c is also fixed to the upper and lower horizontal waists 54 by the cat hardware 56, for example.

  As shown by phantom lines in FIG. 6A, the upper horizontal frame member 41a of the base frame 41 is provided with a bolt portion 42 projecting upward, and the lower horizontal frame member of the base frame 41. You may provide the bolt part 42 which protrudes in upper-lower direction to 41a. Then, the base frame 41 may be fixed to an intermediate portion of the upper and lower lateral trunk edges 54 by inserting the bolt portion 42 into the upper and lower lateral trunk edges 54 and screwing a nut. According to this, the middle portion of the horizontal frame member 41a can also be fixed to the lateral trunk edge 54 to improve the fixing strength.

  Further, as shown in FIG. 8, an opening for an opening facility is formed across the longitudinal direction of the plurality of outer wall panels 5 and 5 attached to the frame 7 of the building, from the indoor side with respect to the opening The opening facility 4 may be attached. According to this, it becomes possible to easily attach the large-sized opening facility 4 straddling a plurality of panels which are not easy to install on the ground assembly frame 1.

  FIG. 9A and FIG. 9B schematically show longitudinal cross sections of the outer wall panels 5 and 5 and the opening equipment arranged along the longitudinal direction thereof. Similarly, FIGS. 10 (A) and 10 (B) schematically show the cross sections of the outer wall panels 5 and 5 and the opening equipment 4 disposed along the longitudinal direction. In the area including the opening in which the opening facility 4 is provided, a lateral trunk 54 which is a part of the opening frame is attached to the lower side of the area including the opening where the opening facility 4 is provided. A lateral body edge 54 which is part of the opening frame on the upper side is attached to the upper outer wall panel 5. Further, the fixing of the opening facility 4 to the outer wall panel 5 is performed, for example, by fixing the vertical frame member 41b of the base frame 41 to the vertical trunk edge 52c. The vertical trunk 52c is provided separately from the vertical trunk 52a, and the vertical trunk 52c and the horizontal trunk 54 are configured to surround the four circumferences of the base frame 41.

  Moreover, as shown in FIG. 11, the said opening installation 4 may be made to be arrange | positioned over the horizontal direction of the several outer wall panel 5. As shown in FIG. In addition, in order to temporarily reinforce the outer wall panel 5, a vertical trunk edge 52d for reinforcement at the time of lifting may be detachably fixed to the outer wall panel 5.

  Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiment within the same or equivalent scope of the present invention.
