The space between the upper and lower sides and the left and right sides of the building is set up, and as shown in FIGS. The new outer wall material 8 is constructed using 4 as shown in FIG. 10 and FIG.

In this embodiment, as shown in FIG. 8 and FIG. 10, for the portion where the vertical trunk 4a is applied to the layer boundary H of the upper and lower floors of the building in the vertical direction, the trunk 3 is attached to the vertical They are installed at intervals in the direction and are constructed so as to pass the longitudinal trunk 4a in the longitudinal direction. On the other hand, in the base portion 6 of the foundation, the body edge mounting bracket 3 is installed in the lateral direction, and the lateral body edge 4b is provided in the lateral direction.

As for the raised corner portion of this embodiment, as shown in FIG. 9, there is no foundation for supporting the existing outer wall 1 suitable for fixing the body rim mounting bracket 3 to the back side portion of the existing outer wall 1 The side corner 9 is fixed to the existing outer wall 1 and is fixed to the rim attachment bracket 3 fixed to the L-shaped ruler angle 2 or the exterior base material mounting bracket Z at a location other than the exit corner. Fixing to the L-shaped ruler angle 2 by fixing to the torso edge 4 branched from the longitudinal torso edge 4 a fixed to the L-shaped ruler angle 2 or to the branched torso 4 using the connection fitting J etc. A rigid support can be obtained as in the case of the body rim 4 fixed via the fitting 3.

Here, when fastening the shell edge mounting bracket 3 to the existing outer wall 1 at the middle portion of the shell edge 4, for example, the anchor A and the anchor bolt B are used in addition to the fixing tool α such as a screw. You may fasten it.

FIG. 12 shows an example of an exterior base material mounting bracket Z used in the present invention.

An exterior base material mounting bracket Z shown in FIG. 12 (a) is a base portion 6 of a base on which a mounting portion T on a vertical plane for mounting the body edge mounting bracket 3 and the body edge 4 and an exterior base material mounting bracket Z are provided. The first support piece 21 having a fixing hole β, into which the fixing tool α can be inserted from the front upper side of the mounting material base mounting bracket Z and fixed when fixed to the mounting part T, and the mounting portion T and the first support piece 21 And a second support piece 22 for supporting the exterior base material mounting bracket Z in a self-supporting manner.

The back side of the first support piece 21 is inclined upward in the vertical direction so that the fixing hole β can be raised so that the fixing tool α can be inserted from the front upper side into the fixing hole β. doing. That is, the first support piece 21 is formed so as to be inclined vertically downward toward the front side of the mounting portion T and vertically upward toward the rear side of the mounting portion T.

The front support end 23 is an end on the front side of the first support piece (the end under the inclination of the first support piece), and is used to improve the self-supporting stability of the exterior base material mounting bracket Z and the grip performance. It is formed so as to be grounded when placing the exterior base material mounting bracket Z.

The second support piece 22 is formed by bending the tip of the support piece top 24 which is the upper end of the first support piece 21 obliquely upward toward the vertical direction, and is the end of the second support piece 22. The rear support end portion 25 is grounded so as to support the exterior base material mounting bracket Z, and the exterior base material mounting bracket Z is formed so as to stand on its own.

Here, the rear support end 25 of the second support piece 22 is formed to be more rearward than the vertically lower side of the support piece top 24 which is the upper end of the slope of the first support piece 21, and If the support piece 22 has an inclination of the lower rear side of the exterior base material mounting bracket Z, and the rear support end 25 of the second support piece 22 having such an inclination is grounded, the exterior The self-supporting stability of the base material mounting bracket Z is improved, the gripability of the rear support end 25 at the ground contact portion is improved, and the shift when fastening the fixture α to the exterior base material mounting bracket Z is prevented. An effect etc. are obtained.

Furthermore, as in the example shown in FIG. 12 (b), the exterior base material attachment bracket Z of the present invention is the front support end 23 of the first support piece 21 and the rear support end 25 of the second support piece 22. By providing a convex support projection Y in which the ground contact portion makes point contact or the ground contact bite, the grip property of the exterior base material mounting bracket Z with respect to the ground contact portion is improved, and the exterior at the time of construction The effect of preventing the displacement of the base material mounting bracket Z can be obtained.

Moreover, various shapes other than this can be considered about the shape of the exterior base material attachment metal fitting Z of this invention. For example, as shown in FIG. 12C, the second support piece may be formed by bending the side end of the first support piece.

FIGS. 13 and 15 to 17 show examples of the shell edge mounting bracket 3 used in the present invention.

As shown in FIG. 13, the shell edge mounting bracket 3 is a screw for fixing the shell edge mounting bracket 3 to the existing outer wall 1 or the base supporting the existing outer wall 1, the outer base material mounting bracket Z, etc. A fixing portion 10 having a substantially square shape for attaching a fixing tool α such as an anchor bolt B, a bending surface 11 raised vertically upward from one end of the fixing portion 10 in the left-right direction, and one end of the bending surface 11 And a central piece 12 raised vertically upward from both end portions in the vertical direction of the fixed portion 10, the central piece 12 extending under the construction surface 7 It has a central half extension 13.

There is an upper receiving portion 14 on the side facing the back side of the construction surface 7 of the central partial extension 13, while the back side of the construction surface 7 receives the top when the construction surface 7 tries to deform to the existing outer wall 1 side. There is an upper contact portion 15 in contact with the portion 14.

  In the fixing portion 10, a fixing hole β for inserting a fixing tool α such as a screw or an anchor bolt B is formed.

As shown in FIG. 14, at the time of driving the fixing tool α at the time of mounting the body edge 4 to the body edge mounting bracket 3, an external force F in the indoor direction is applied to the construction surface 7 of the body edge mounting metal fitting 3. In such a case, according to the shell edge mounting bracket 3 as shown in FIG. 13, in particular, there is a gap between the shell edge mounting bracket 3 and the existing outer wall 1. Even if the upper receiving portion 14 of the center piece extension 13 receives and supports the upper contact portion 15 on the back surface side of the work surface 7, the strength of the body edge mounting bracket 3 against the external force F increases. The deformation due to the external force F at the time of driving the fixing tool α can be prevented. As a result, even if there is a non-landing on the existing outer wall 1, for example, non-landing adjustment such as inserting the spacer S below the body edge mounting bracket 3 can be performed without any problem.

  Further, the body edge mounting bracket 3 shown in FIG. 15A is intended to be deformed in such a direction that the construction surface 7 is separated from the side of the existing outer wall 1 where the fixing portion 10 is located at the central piece extension 13. At the time, there is a lower receiving portion 17 that prevents the deformation by contacting the side piece 16. The portion of the side piece 16 in contact with the lower receiving portion 17 is a lower contact portion 18.

According to the body edge mounting bracket 3 shown in FIG. 15 (a), in addition to the deformation preventing effect of the body edge mounting metal fitting 3 shown in FIG. By forming a shape that engages with the deformation in the upper and lower directions, deformation on the opposite side to that in the case of FIG. 14 can also be prevented.

For example, as shown in FIG. 15 (b), when a wind load of negative pressure is applied to the new outer wall material 8 after the installation of the new outer wall material 8, the installation surface 7 of the metal frame mounting bracket 3 also Although an external force F of negative pressure in the outward direction acts, the lower receiving portion 17 of the central extension 13 receives and supports the lower contact portion 18 of the side piece 16 so that The strength of the mounting bracket 3 against the external force F is increased, and the wind pressure resistance of the shell edge mounting bracket 3 is improved.

16 (a), when the mounting surface 7 and / or the bending surface 11 is to be deformed in the direction away from the center of the fixing portion 10 in the central piece extension 13. There is a side receiving portion 19 that prevents the deformation by contacting the side piece 16. The portion of the side piece 16 in contact with the side receiving portion 19 is a side contact portion 20.

  According to the shell edge mounting bracket 3 shown in FIG. 16 (a), in addition to the deformation preventing effect of the shell edge mounting bracket 3 shown in FIGS. 14 and 15, the construction surface 7 and / or the bending surface 11 is It is also possible to prevent deformation in a direction away from the center of the fixing portion 10. That is, in addition to the shape that engages with the vertical deformation in the vertical direction, the shape also meshes with the deformation in the left-right direction.

  For example, as shown in FIG. 16 (b), the construction surface 7 and / or the bending surface 11 of the shell edge mounting bracket 3 is deformed in the lateral direction of the fixed portion 10 after the shell edge 4 or the new wall material is attached. The side receiving portion 19 of the central extension 13 receives the side contact portion 20 of the side piece 16 even when an external force F such as that generated by a load or a movement of the building due to an earthquake or the like acts. By being supported, the strength of the body edge mounting bracket 3 can be increased, and the deformation of the body edge mounting fitting 3 due to such an external force F can be prevented.

Of course, for deformation where the construction surface 7 and / or the bending surface 11 approaches toward the center direction of the fixed portion 10, it is for the mounting of the body edge shown in FIG. 13 (b), FIG. 15, FIG. In the case of the metal fitting 3, the central piece or the central piece extension 13 and the side piece 16 are in contact with each other, and the deformation thereof can be prevented.

As shown in FIG. 17A, as another shape of the body edge mounting bracket 3, there is no center piece extension 13 and the body edge mounting fitting 3 is deformed toward the existing outer wall 1 side. When the side piece 16 is in contact with the central piece 12 so as to prevent deformation. Alternatively, the side piece 16 and the bending surface 11 may be in contact with each other to prevent deformation, and as shown in FIGS. 17 (b) and 17 (c), there is no central extension 13; Even if the central piece 12 side is retracted and the side piece 16 side is extended as in the shape of the side piece 16 like the 16 body edge mounting brackets 3, as in FIG. 15 and FIG. Can be obtained.

Further, as shown in FIG. 13 and FIGS. 15 to 17, the shell edge mounting bracket 3 forms the construction surface 7 on the left and right sides of the fixed portion 10, thereby forming two shell edges 4 into one. It becomes easy to attach to the body edge mounting bracket 3, and as shown in FIG. 6 to FIG. 8 and FIG. 10, when installing the body edge 4 so as to connect the body edge 4 in the vertical and horizontal directions The reduction in the amount of time and effort required for the installation, and the reduction in the amount of materials used for the fixing tool α and the members can be expected.

In particular, as shown in FIG. 6, in the case of fixing to the L-shaped ruler angle 2 located at the joint of the panel of the existing outer wall 1 at the layer boundary H of the upper and lower floors, Fixation allows the two vertical torso edges 4a to be connected in a row in the vertical direction of the building to the L-shaped ruler angle 2 where the area that can be fixed is narrow, so that the workability is improved. improves.

In addition, even if the construction surface 7 of the shell edge attachment 3 is one, if the area of the construction surface 7 is wide, it is possible to attach two trunks 4 to one construction surface 7 as a matter of course.

FIG. 18 shows an example of the body edge 4 used in the present invention. The shape of the body rim 4 to be used includes a generally known hat-shaped shape shown in FIG. 18 (a) and a shape shown in FIG. 18 (b) and FIG. 18 (c). . In addition, in places where the new outer wall material 8 is to be a lateral joint, there may be a case where the body edge 4 on a wide width is used to construct a member for the lateral joint, as shown in FIG. In some cases, a squid-head like an out-corner body rim 9 is used for the out-corner portion.

Examples of the material of the body edge mounting bracket 3 and the body edge 4 include high corrosion resistant steels such as hot-dip zinc-aluminum-magnesium alloy plating and metals such as aluminum and stainless steel, but the material is particularly limited. It is not a thing. In general, although the metal fitting is mainly described as a metal fitting, it may not be a metal fitting.

The fixing hole β of the body edge mounting bracket 3 and the body edge 4 is preferably a long hole in consideration of the in-plane pursuit, as a measure when the existing outer wall 1 moves due to a shaking such as an earthquake. As a result, even if a slight shift in movement occurs between the existing outer wall 1 with the fixing tool α and the fixing hole β, the shift can be absorbed. In particular, in the case where the existing outer wall 1 is the vertical wall locking method of ALC, the L-shaped ruler angle 2 is used at the portion of the existing outer wall 1 located in the center in the panel width direction. Since the existing ALC metal fitting K is present, the effect is exhibited in the case where the installation position of the body edge mounting metal fitting 3 is shifted from the center in the panel width direction to avoid installation.

FIG. 19 shows an embodiment of the invention in the parapet part of a building. For example, as shown in FIG. 19, in the parapet portion of a building in which the existing outer wall 1 is an ALC outer wall, the existing outer wall 1 of the floor just below the roof is extended in the direction of the roof, and the hierarchical boundary between the roof and the floor just below the roof There is a case that there is no boundary of the existing outer wall 1 in H.

Here, similarly to the lower floor, the trunk edge mounting bracket 3 is fixed to the L-shaped ruler angle 2 which is the base of the existing outer wall 1 present at the hierarchical boundary H between the roof and the floor directly below it with the fixture α. The vicinity of the upper end portion of the vertical trunk 4 a is fixed to the construction surface 7 of the trunk edge mounting bracket 3. Furthermore, it is preferable to fix the vertical trunk edge 4a to the existing outer wall 1 extended in the rooftop direction just in case.

An example of the Example of this invention in the opening part W of a building is shown in FIG. 20 (a) is a front view of the opening, FIG. 20 (b) is a vertical cross section, and FIG. 20 (c) is a reference view showing a horizontal cross section. As in the example of this opening, in the place where there is an obstacle that obstructs the continuous formation of the vertical torso edge 4a, the presence or absence of the base of the existing outer wall 1 at that place, the horizontal member or the vertical member, the opening In consideration of the manner of construction around the part, the required strength, etc., the selection of the mounting method of the body edge, the presence or absence of the metal frame mounting bracket, the presence or absence of the lateral body edge 4b, etc. are determined.
