BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a body edge mounting structure according to the present invention. FIG. 1 shows a typical example of a body edge mounting structure of the present invention.
Is a fixing bracket, B is a rim, C is an existing outer wall, D is asphalt felt, and E is a new outer wall.

The fixing bracket A is, for example, formed by molding various lightweight steel materials into a predetermined shape. The fixing bracket A reinforces the fixing of the rim B to the existing outer wall C at a plurality of positions on the rim B. The shape can be, for example, as shown in FIG. That is, the fixing bracket A includes a horizontal contact piece 1, a side piece 2 in which both side ends of the contact piece 1 are bent downward, and a horizontal fixed piece 3 in which the lower end of the side piece 2 is bent outward. The protruding portion 4 in which the inner piece 5 and the outer piece 6 are formed by bending the end of the fixing piece 3 into a mountain shape, and the projecting portion 4 is formed so that the tip of the outer piece 6 is located on the same plane as the fixing piece 3 A groove 8 surrounded by the contact piece 1 and both side pieces 2 is formed, and the outer piece 6 and the auxiliary piece 7 have an obtuse angle.

The fixing of the rim B to the existing outer wall C is shown in FIG.
As shown in (b), the surface is brought into contact with the contact piece 1 while fitting the body rim B in the groove 8 of the fixing metal A, and the outer piece 6 is perpendicular to the outer piece 6 by the fixing tool β. Is performed.

The outer piece 6 has an obtuse angle with respect to the auxiliary piece 7, that is, as shown in FIG. 2C, which is an enlarged view of a range a surrounded by a dotted line in FIG. The angle θ is preferably about 45 degrees in consideration of the mounting strength of the fixture A to the existing outer wall C, the ease of driving the fixture β, and the like. The contact piece 1 and the outer piece 6 are respectively provided with fixing holes 11,
By providing 12, the driving of the fixing tool β can be facilitated.

The driving by the fixing tool β is performed perpendicularly to the outer piece 6 having an angle θ with respect to the surface of the existing outer wall C,
Moreover, since the fixing is performed by the outer pieces 6 on both sides, each fixing tool β is driven at a different angle with respect to the surface of the existing outer wall C. For this reason, the rim B reinforced by the fixing bracket A is a force that tends to pull out, especially the existing outer wall C.
It can have a considerable resistance to the force of pulling out perpendicular to the surface, and the mounting strength is improved. Particularly, when the existing outer wall C is made of a fragile ALC outer wall, it is effectively used. Works.

The rim B may be made of a commonly used wood, but may also be formed by bending various steel plates, extruding an aluminum material in a hollow or U-shape, or made of a synthetic resin. Can also be used.
FIG. 2B shows an example in which the rim B is made of a wooden material having a rectangular cross section. However, as a cross-sectional shape when the rim B is formed of various materials as described above,
Any shape may be used as long as the surface of the body edge B is housed in the groove 8 while being in contact with the contact piece 1.

The existing outer wall C is, for example, a wall formed by an ALC outer wall, D is an asphalt felt, E is a new outer wall for repairing the existing outer wall C, but the new outer wall E is easy to construct. It is preferable to use a metal siding material from the viewpoint that the load on the existing outer wall E can be reduced due to its light weight, and heat insulation can be added simultaneously with the construction.

The construction process of the body edge mounting structure according to the present invention will be described below. First, as shown in FIG.
The rim B is previously attached to the surface of the existing outer wall C with a fixture or an adhesive. Next, at a plurality of positions in the longitudinal direction of the body rim B, the groove B
And the surface of the torso B is brought into contact with the contact piece 1 of the fixing bracket A, and the contact piece 1 is driven into the existing outer wall C through the fixing hole 11 by the fixing tool α, so that the fixing fitting A is Fix to torso rim B.

Next, as shown in FIG. 4, the outer pieces 6 on both sides of the fixing bracket A are driven perpendicularly to the outer pieces 6 so that both fixing tools β are different from the surface of the existing outer wall C. By injecting at an angle, it is possible to form the rim B having a strong resistance to the force of pulling outward. Needless to say, the fixing tool β in this case uses a concrete nail, an anchor bolt, or the like.

Next, as shown in FIG. 1, the renovation of the existing outer wall C is completed by stretching the asphalt felt D on the waist edge B or arranging a new outer wall E. Of course, the asphalt felt D may be directly stretched on the existing outer wall C.

What has been described above is merely an embodiment of the body edge mounting structure according to the present invention, and the following configuration can be adopted. That is, FIGS. 5A to 5C show modified examples of the fixing bracket A, and FIG.
5B shows an example in which the depth of the fixing bracket A is large and the fixing piece 3 is divided into front and rear parts, and FIG. 5C shows the fixing of the side piece 2 and the fixing piece 3 FIG. 5 shows an example in which the connection is made with the inclined piece 9 having the hole 13 so that the driving can be performed not only on the outer piece 6 but also on the inclined piece 9.
(A) to (c) are examples in which the mounting strength of the existing outer wall C of the rim B is improved. The fixing bracket A shown in FIG. 5B is used as shown in FIG. 6, and the fixing bracket A shown in FIG. 5C is used as shown in FIG.

Further, the fixing bracket A shown in FIG.
As shown in FIG. 8, not only the outer piece 6 but also the inner piece 5 is used for driving, so that the mounting strength of the rim B can be further improved.

FIG. 9 shows that the side piece 2 is inclined and the groove 8 is formed.
Is an example in which fitting of the body edge B into the groove 8 is facilitated by forming a trapezoidal shape. FIG. 10 shows an example in which the inner piece 5 is bent perpendicular to the fixed piece 3, but does not affect the driving from the outer piece 6.

[0018]

As described above, according to the mounting structure of the waist edge according to the present invention, the fixing tool is driven perpendicularly to the outer pieces and the inner pieces on both sides, that is, obliquely to the existing outer wall. The rim can be firmly fixed even on a fragile existing base such as an aging ALC, and the resistance to the pulling-out force can be particularly increased. After the fixing bracket is fixed to the body edge by driving from above the contact piece, driving is performed from above the inclined piece, so that driving with the fixing bracket is easy. There are features and effects such as.
