  Since the invention according to the invention [6] specifies the construction method in the outer wall panel mounting structure of the invention [1], it is possible to form the outer wall panel mounting structure having the same effect as described above. it can.

  1-3 is a figure which shows the attachment structure of the outer wall panel which is embodiment of this invention. As shown in these drawings, in the present embodiment, the outer wall panel (6) is applied to the wall surface (71) of the building (7) using the trunk edge (1) and the mounting bracket (2). Is.

  First, the outer wall of the building (7) is constituted by a concrete frame made of a precast concrete panel or the like.

  The trunk edge (1) is constituted by a mountain-shaped metal plate (steel plate) having an L-shaped cross section having a vertical flange (11) and a horizontal flange (12).

  The trunk edge (1) has the vertical flange (11) arranged along the wall surface (71) and the horizontal flange (12) projected forward (outward) perpendicular to the wall surface (71). As shown in the figure, the vertical flange (11) is penetrated by a plurality of fixing devices (3) such as a spread leg nail, anchor bolt and spread leg bolt at predetermined intervals in the lateral direction (length direction). And fix each to the building (7). Accordingly, the trunk edge (1) is fixed along the wall surface (71) in a state where the trunk edge (1) is arranged so as to be continuous in the lateral direction (horizontal direction) along the wall surface (71).

  A plurality of trunk edges (1) are fixed to the wall surface (71) at a predetermined interval in the vertical direction (vertical direction) at a pitch corresponding to the vertical dimension (vertical dimension) of the outer wall panel (6).

  As shown in FIGS. 1 to 5, the mounting bracket (2) is formed of a metal plate molded product having a thickness of about 2 to 3 mm. The mounting bracket (2) includes a flat plate body (20) having a rectangular shape in plan view with a longitudinal length of about 30 mm and a lateral length of about 60 mm, and an intermediate portion of the front edge of the flat plate body (20) is Bending upward to form an upward bent piece (21), both sides of the front end are bent downward to form downward bent pieces (22) and (22).

  Further, the mounting bracket (2) has three screw holes (24) formed in the flat plate body (20). The screw holes (24) are formed at predetermined intervals in the lateral direction, and intermediate screw holes (24) are arranged slightly forward compared to the screw holes (24) (24) on both sides.

  The mounting bracket (2) has a rear portion of the flat plate body (20) disposed on the horizontal flange (12) of the trunk edge (1), and has an upward bent piece (21) and a downward bent piece (22 ) Are arranged at positions projecting forward from the front end of the horizontal flange (12), and the three tapping screws (4) are screw holes (24) of the flat plate body (20) in the mounting bracket (2). And is fixed to the trunk edge (1) by being screwed into the horizontal flange (12) of the trunk edge (1). In this way, many mounting brackets (2) are fixed at predetermined intervals in the length direction of the trunk edge (1).

  As shown in FIG. 6, the outer wall panel (6) is made of a stone processed product having a thickness of about 18 mm, and has a square shape with a vertical size of 600 mm and a horizontal size of 600 mm. An upper edge mounting groove (61) and a lower edge mounting groove (62) are formed along the respective edges at the upper edge and the lower edge of the outer wall panel (6).

  A large number of outer wall panels (6) are arranged in a plane along the building wall surface (71) vertically and horizontally, and the upper and lower edges of each outer wall panel (6) are attached to the mounting bracket (2 ) And the trunk edge (1), respectively, to the building wall surface (71). That is, as shown in FIGS. 2 and 7, in the lower edge mounting groove (62) of the outer wall panel (6), the (lower) mounting bracket (2) is folded upward so as to correspond to the groove (62). While the bent piece (21) is inserted, a downward bent piece (22) of the (upper) mounting bracket (2) disposed in the upper edge mounting groove (61) corresponding to the groove (61) is provided. By being inserted, the upper and lower ends of the outer wall panel (6) are supported and fixed to the wall surface (71) of the building (7) via the corresponding upper and lower mounting brackets (2).

  Thus, a large number of outer wall panels (6) are arranged in a plane along the wall surface (71) in a state where gaps are formed forward (outward) between the building wall surface (71).

  The joints between the adjacent outer wall panels (6) are filled with a caulking agent (not shown) so as to seal between the adjacent outer wall panels.

  Here, in this embodiment, as shown in FIG. 7, the vertical lengths (H1) and (H2) of the upward bent piece (21) and the downward bent piece (22) of the mounting bracket (2) are both 2 to 2. It is good to set to 8 mm, More preferably, it is 3-7 mm, More preferably, it is good to set to 4-6 mm. That is, when the lengths (H1) and (H2) of the bent pieces (21) and (22) are too short, the mounting grooves (61) and (62) of the outer wall panel (6) of the bent pieces (21) and (22). When the amount of insertion (engagement amount) with respect to is not sufficiently secured and a great amount of stress is applied, the bent pieces (21) and (22) are unintentionally detached from the mounting grooves (61) and (62). The outer wall panel (6) may come off. Conversely, when the lengths (H1) and (H2) of the bent pieces (21) and (22) are too long, the mounting grooves (61) and (62) of the outer wall panel (6) of the bent pieces (21 and 22). ), The insertion work, and hence the panel mounting work becomes difficult, and in order to secure a large insertion quantity, the groove depths of the mounting grooves (61) and (62) are deepened. This is not preferable because the strength of the outer wall panel (6) is reduced, and breakage such as cracks and chips are likely to occur around the mounting groove. Therefore, in this embodiment, by setting the lengths (H1) and (H2) of the bent pieces (21) and (22) within the specific range, the workability, the mounting strength of the panel, and the strength of the panel itself are improved. be able to.

  Moreover, in the mounting bracket (2) of this embodiment, it is good to form more downward bending pieces (22) than the number of upward bending pieces (21). That is, in the present embodiment, the upper edge of the outer wall panel (6) is supported by the downward bent piece (22), and the lower edge of the outer wall panel (6) is supported by the upward bent piece (21). However, when a greater vibration is applied to the occurrence of an earthquake, for example, the mounting bracket (2) on the upper edge side is removed compared to the mounting bracket (2) on the lower edge side of the outer wall panel (6). Will be more likely to do. Therefore, as in the present embodiment, the number of downward bent pieces (22) supporting the panel upper edge side in the mounting bracket (2) is larger than the upward bent pieces (21) supporting the panel lower edge side. By forming, the mounting bracket (2) on the upper edge side of the panel is less likely to come off compared to the mounting bracket (2) on the lower edge side of the panel, and the mounting bracket ( 2) can effectively prevent the outer wall panel (6) from being detached, and the outer wall panel (6) can be firmly attached in a stable state.

  Further, in the mounting bracket (2) of the present embodiment, the bent portion (25) of the upward bent piece (21) and the downward bent piece (22) is formed in an arc shape by bending. Specifically, the curvature radius of the outer peripheral surface (26) in the bent portion (25) of the bent pieces (21) and (22) is 1.5 to 5.0 mm, and the curvature radius of the inner peripheral surface (27) is 1. .0 to 2.5 mm. Since the bent portions (25) of the bent pieces (21) and (22) are formed in an arc shape by bending as described above, the support load of the panel (6) is locally applied to the bent portions (25). Concentration can be prevented and the panel load can be distributed over a wide range. Thereby, the load resistance of the bent pieces (21) and (22) can be improved, the durability of the mounting bracket (2) can be improved, and as a result, the durability of the entire panel mounting structure can be improved. .

  Moreover, in this embodiment, it is good to set the groove depth (D) of the upper-and-lower-edge mounting groove (61) (62) of an outer wall panel (6) to 2-8 mm. That is, if the groove depth (D) is too shallow, the insertion amount of the bent pieces (21) and (22) in the mounting bracket (2) cannot be secured sufficiently, and when a large amount of stress is applied, the folding pieces (21) and (22) are folded. There is a possibility that the curved pieces (21) and (22) may be unintentionally detached from the mounting grooves (61) and (62), and the outer wall panel (6) may come off. On the other hand, when the groove depth (D) is too deep, the strength around the groove is lowered, and breakage such as cracks and chips is likely to occur around the groove, which is not preferable. Therefore, in this embodiment, the mounting stability of the panel and the strength of the panel itself can be improved by setting the groove depth (D) of the outer wall panel (6) within the specific range.

  Furthermore, in this embodiment, the groove width (W) of the upper and lower edge mounting grooves (61) (62) of the outer wall panel (6) may be set to 2 to 4 mm, more preferably 2.5 to 3.5 mm. More preferably, it should be set to about 3 mm. That is, if the groove width (W) is too narrow, it becomes difficult to insert the bent pieces (21) and (22) of the mounting bracket (2) into the mounting grooves (61) and (62). It is necessary to use a thin mounting bracket (2) in accordance with the width of the mounting grooves (61) and (62), and the mounting bracket (2) has sufficient strength. It may be difficult to ensure. Conversely, when the groove width (W) is too wide, the thickness (L) of the groove side walls (63) and (63) on both sides of the groove becomes relatively thin, the strength of the groove side wall (63) decreases, and cracks occur. It is not preferable because breakage such as cracks and cracks are likely to occur. Therefore, in this embodiment, the workability and panel strength can be improved by setting the groove width (W) of the mounting grooves (61) and (62) in the outer wall panel (6) within the specific range.

  Furthermore, in this embodiment, the thickness (L) of the groove side walls (63) on both sides of the groove at the upper and lower ends of the outer wall panel (6) may be set to 5 to 10 mm, and more preferably set to 7 to 9 mm. good. That is, when the groove side wall thickness (L) is too thin, the strength of the groove side wall (63) is lowered, and there is a possibility that breakage such as cracking or chipping may occur. Conversely, when the groove sidewall thickness (L) is too thick, the groove width (W) of the mounting grooves (61) (62) is relatively narrow, and the mounting bracket (61) (62) has a mounting bracket (61). It becomes difficult to insert the bent pieces (21) and (22) of 2), the workability of the work is lowered, and the mounting bracket (2) is adjusted in accordance with the width of the mounting grooves (61) and (62). Therefore, it may be difficult to secure sufficient strength of the mounting bracket (2). Therefore, in this embodiment, the workability and panel strength can be improved by setting the groove sidewall thickness (L) of the outer wall panel (6) within the specific range.

  Further, in the present embodiment, the thickness (L) of the groove side wall (63) on both sides of the groove is set thicker than the groove depth (D) of the upper and lower edge mounting grooves (61) and (62) in the outer wall panel (6). Specifically, it is preferable to establish a relationship of “groove sidewall thickness (L)” ≧ “groove depth (D)”. That is, when the groove side wall thickness (L) is smaller than the groove depth (D), the strength of the groove side wall (63) is lowered, and breakage such as cracks and chips is likely to occur. In other words, when the relationship of “groove side wall thickness (L)” ≧ “groove depth (D)” is established in the present embodiment, sufficient strength can be ensured in the outer wall panel (6). .

  Furthermore, in this embodiment, it is good to set the plate | board thickness of an outer wall panel (6) to 12-25 mm, It is good to set to 16-20 mm more preferably. That is, when the panel thickness is too thin, it is difficult to ensure sufficient panel strength, and the panel (6) is liable to be damaged such as cracks and chips, which is not preferable. Conversely, if the panel is too thick, the panel (6) will be heavy, making it difficult to handle during assembly work, and not only reducing work efficiency, but also the weight of the panel after construction. There is a possibility that the load becomes large and the durability is lowered. Therefore, in this embodiment, the panel strength, workability, and durability can be improved by setting the plate thickness of the outer wall panel (6) within the specific range.

  Although the construction procedure of the outer wall panel mounting structure having the above configuration is not particularly limited, for example, the construction is performed by the following procedure.

  First, on the wall surface (71) of the building (7), the vertical edge (11) is placed along the wall surface (71) so that the body edge (1) is directed in the lateral direction, and the horizontal flange ( 12) is horizontally disposed forward (outward) with respect to the wall surface (71), and in this state, a plurality of fasteners (3) provided with vertical flanges (11) at predetermined intervals in the length direction thereof. ) To fix. Thus, a plurality of trunk edges (1) are arranged on the building wall surface (71) in a state in which a plurality of trunk edges (1) are arranged at predetermined intervals in the vertical direction (vertical direction) at a vertical pitch corresponding to the height dimension of the outer wall panel (6).

  Subsequently, the outer wall panel (6) is constructed from the lower side to the upper side sequentially through the mounting bracket (2). First, a plurality of mounting brackets (2) are fixed to the lowermost trunk edge (1) at predetermined intervals in the length direction, for example, at a pitch of 150 to 450 mm. At this time, each mounting bracket (2) is fixed to the horizontal flange (12) of the trunk edge (1) by three tapping screws (4).

Thus, the first-stage outer wall panel (6) is constructed with its upper and lower ends supported and fixed to the wall surface (71) via the mounting bracket (2). In the same manner, a plurality of outer wall panels (6) are sequentially constructed in the horizontal direction in the first stage.

  Next, the upward bent piece (21) of the mounting bracket (2) attached to the second-stage trunk edge (1) is inserted into the lower-edge attachment groove (62) of the second-stage outer wall panel (6). The lower end of the second stage outer wall panel (6) is supported. Temporarily hold in that state, and insert the downward bent piece (22) of the mounting bracket (2) into the upper edge mounting groove (61) of the second-stage outer wall panel (6) The metal fitting (2) is fixed to the third-stage trunk edge (1) via a tapping screw (4). In this way, a plurality of outer wall panels (6) are sequentially constructed in the horizontal direction in the second stage.

  Further, in the same manner as described above, the third and subsequent outer wall panels (6) are sequentially constructed, and a large number of outer wall panels (6) are attached in a planar arrangement over a predetermined region of the building wall surface (71).

  As described above, according to the mounting structure of the outer wall panel of the present embodiment, the mounting bracket (2) has a very simple structure in which only the bent pieces (21) and (22) are provided at the front end of the flat plate body (20). Therefore, the mounting bracket (2) can be easily manufactured, and the productivity can be improved and the cost can be reduced.

The position can be easily and accurately aligned. As described above, since the mounting brackets (2) can be smoothly aligned, the working efficiency can be further improved.

  Furthermore, in the above embodiment, the mounting bracket (2) is screwed and fixed to the trunk edge (1) using the tapping screw (4), so the mounting position of the mounting bracket (2) with respect to the trunk edge (1) Can be set freely, and the mounting position of the mounting bracket (2) can be easily adjusted. In this respect, the mounting workability can be further improved.

  In the present embodiment, the mounting grooves (61) (62) provided on the upper and lower edges of the outer wall panel (6) are continuously formed along the upper and lower ends. The bent pieces (21) and (22) can be attached at any position within the range of the attachment grooves (61) and (62) of the outer wall panel (6). Accordingly, the lateral displacement of the outer wall panel (6) can be easily adjusted, and the panel (6) can be attached more easily.

  Moreover, in this embodiment, the trunk edge (1) continuous in the horizontal direction is fixed to the building wall surface (71), and the mounting bracket (2) is screwed to the trunk edge (1) at predetermined intervals. Therefore, for example, compared to a case where a large number of mounting brackets are individually fixed to the wall surface by anchor bolts or the like, the mounting operation of the mounting bracket (2) can be performed more efficiently and smoothly.

  Furthermore, in this embodiment, since the mounting bracket (2) can be formed thin while ensuring rigidity, the mounting grooves (61) (62) of the outer wall panel (6) are adapted to the thickness reduction of the mounting bracket (2). ) Can be made smaller, and a panel having a thinner panel thickness can be used, and the weight of the outer wall panel itself can be reduced. Therefore, the handling work of the panel (6) can be easily performed, and the workability can be further improved. For example, the assembly work can be easily performed by one person work.
