Description

  The present invention relates to an outer wall panel mounting structure of a unit building and a mounting method thereof.

Conventionally, in this type of unit building outer wall panel mounting structure, outer wall panels are attached to a unit building so as to block between unit columns of individual building units constituting the unit building. Specifically, since the unit column has a large hollow rectangular cross section, the hollow rectangular cross-section frame frame fixed to the outer wall panel and the unit column are directly fixed with screws or rivets. It is difficult to set up an L-shaped stud that is not a steel closed cross section in the center side of one side edge of the building unit in the vicinity of the unit column in parallel. The outer panel was attached to the building unit.
JP-A-8-60767

  However, an L-shaped stud is arranged in the vicinity of the unit column in the vicinity of the unit column on the center side of one side edge in parallel with the unit column, and the vertical edge of the outer wall panel substantially aligned with the outer side surface of the unit column is L Since it is a cantilevered free end that is horizontally separated from the letter-shaped stud, the vertical edge of the outer wall panel may be warped or floated, which may cause problems in appearance and waterproofing. In addition, a step may be generated between the outer wall panels of adjacent building units, which may similarly cause a problem in appearance and waterproofing.

  Accordingly, it is an object of the present invention to provide a mounting structure for an outer wall panel of a unit building that is excellent in appearance and waterproof surface in which the vertical edge of the outer wall panel does not warp, float, or step.

  In order to achieve this object, according to the present invention, a frame frame body is fixed to the vertical edge portion of the back surface of the outer wall panel along the vertical edge, and the back surface of the frame frame body and the surface of the unit column face each other. An outer wall panel mounting structure for a unit building in which the vertical edge is assembled so as to be substantially flush with the outer side surface of the unit column, and at least the outer side surface of the frame frame and the outer side surface of the unit column are The outer wall panel mounting structure of the unit building is characterized in that the upper and lower two locations are connected by connecting members.

  According to the configuration of the present invention, the vertical edge of the outer wall panel, which has conventionally been a free end with respect to the unit column, is fixed by the frame frame, so the vertical edge of the outer wall panel is warped, floated, or stepped. It is possible to obtain an outer wall panel mounting structure that is satisfactory in terms of appearance and waterproofing. Furthermore, since the conventional L-shaped stud is not necessary if the inner wall panel is to be mounted, the outer wall panel mounting structure of the unit building can be made excellent in terms of man-hour and price.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The unit building is generally constructed in a one-story building or two-story building by transporting a plurality of building units X, Y produced in a factory to the site, and joining and assembling them left and right and up and down.

  These building units X and Y are connected to the frame structure by welding grooved steel floor beams and ceiling beams (not shown) to the upper and lower ends of the unit columns 30 and 40 made of steel square pipes at the four corners. Formed into a box-shaped frame structure.

  In this unit building, the unit columns 30 and 40 of these building units X and Y are assembled with bolts, nuts, etc., and depending on the location, the unit columns 30 and 40 have one position, two positions, and four positions. Can do.

  The outer wall panel structures 10 and 20 include outer wall panels 11 and 21 each having a rectangular size with one or a plurality of unit pillars 30 and 40 on the outer wall side, and vertical end edges on the back surface, that is, The frame frames 12 and 22 fixed along the vertical edge 11a and 21a at a position slightly inside from the vertical edges 11a and 21a and the frame frames 12 and 22 are connected at least in the vertical position. The horizontal frame body 14 is configured roughly.

  If necessary, the outer wall panel structures 10 and 20 are provided in the vicinity of the unit pillars 30 and 40 that are substantially flush with the vertical end edges 11a and 21a between the frame frames 12 and 22 on both sides. Auxiliary frame frames 13 and 23 are connected to the upper and lower horizontal frame frames 14.

  Further, the same one of the connecting members 15, 16, and 17 shown in various shapes in FIG. 3 is selected on the outer side surfaces of the frame bodies 12 and 22, and is connected to the unit columns 30 and 40. It is provided at least in two places. Among these, the connecting member 15 is in the form of a strip made of, for example, a steel plate, and is stepped by about this plate thickness perpendicular to the longitudinal direction from one end to a dimension position slightly larger than the side width of the frame frames 12 and 22. 15a is provided. As a result, the thickness of the connecting member 15 is the sum of the step 15a and the plate thickness. Therefore, the outer side surfaces of the frame bodies 12 and 22 are positioned on the inner side by the thickness of the connecting member 15 from the vertical end edges 11a and 21a. In the vicinity of both ends of the connecting member 15, round holes 15 b are formed through which tapping screws fixed to the frame frames 12 and 22 and the unit columns 30 and 40 are passed.

  The connecting member 16 is substantially the same as the connecting member 15, but one of the connecting members 16 is a round hole 16 b and the other is a long hole 16 c, and even after being assembled as the building units X and Y, The distance between the unit columns 30 and 40 can be finely adjusted. That is, the connecting member 16 has a long hole 16c in a facing direction at one of a position in contact with the outer side surface of the frame frames 12 and 22 and a position in contact with the outer side surface of the unit pillars 30 and 40.

  The connecting member 17 is substantially the same as the connecting member 15, but the edge of the frame frame bodies 12, 22 on the side contacting the outer side surfaces 11 a, 21 a is chamfered, and a two-dot chain line is formed at the lower end in FIG. As shown in FIG. 6 (shown only for the frame frame 12 here), the frame can be rotated to a position along the outer side surfaces of the frame frames 12 and 22. An example of the cornering may be a semicircular shape with an R shape as shown in FIG. 3, but may have any cut shape as long as it does not interfere with the back surfaces of the outer wall panels 11 and 21 during rotation. Therefore, the connecting member 17 can be rotated in a range between the direction along the outer side surface of the frame frames 12 and 22 and the facing direction of the frame frames 12 and 22 and the unit columns 30 and 40. Can be stored. If the connecting member 17 is stored along the frame frame 12 before the outer wall panel structures 10 and 20 are attached to the unit columns 30 and 40 to form the building units X and Y, the protrusions are reduced and the conveyance is performed. It does not take up space during lamination, etc., does not come into contact with other things, and produces fewer defective products.
