2. Description of the Related Art When renovating an existing building, a new decorative panel is attached to the outer wall surface. When an opening such as a window is formed on the outer wall surface, it is necessary to perform the construction so that the decorative plate is not positioned at that portion. For this reason, when the decorative board is a long exterior material such as a lightweight concrete board, it is usually cut to an appropriate length at a construction site. Due to such a case, it is inevitable that the end face portion (side end face or cut edge) of the exterior material is exposed around four circumferences of the newly formed opening. Further, there is a possibility that a body edge for attaching the exterior material is exposed. The side edges of the exterior material and the cut edge are not always waterproof enough and lack the appearance of design. Therefore, in the renovated building, the four peripheral surfaces of the newly formed opening are left as they are. This is not preferable, and it is necessary to cover the end face of the newly attached exterior material by some means.

[0003] The present invention has been made in view of the above-described circumstances, and is easy to use when attaching a long exterior material such as a lightweight concrete plate to an outer wall surface when renovating an existing building. Renovation that can reliably prevent rainwater from entering around the newly formed opening, and can also improve the appearance design around the newly formed opening. An object of the present invention is to provide a construction method around the opening at the time, and a decorative member around the opening used in the construction method.

A 90-degree bent corner member disposed at the four corners around the new opening, and a connector that preferably connects the linear member and the corner member. Features.

According to the present invention, a vertical waist edge and a horizontal waist edge are attached around an opening, such as a window of an existing building, by appropriate means such as nailing or screwing, and utilized therewith. The decorative member made of the extruded aluminum product is fixed, so that the work of attaching the decorative member at the time of remodeling is easy and secure fixing is obtained. Further, the required water stoppage between the existing opening and the new opening is easily ensured. Since all the end faces (side end faces and cut edges) of the exterior material to be newly attached are covered from outside by the insertion grooves in the decorative member, rainwater can enter inside from around the newly formed opening. However, at the same time, the appearance design around the opening is also improved. Furthermore, as described above, the decorative member is an extruded product of aluminum, and is configured as an aggregate of upper and lower and left and right linear members, a corner member bent at 90 degrees, and a connector. In addition to being able to easily have a high appearance design, it is also possible to easily and properly perform renovation work on openings of various different dimensions only by changing the length of the linear member. it can.

In a preferred embodiment, the linear member and the corner member constituting the decorative member are provided with a base flat surface serving as a fixing surface to a newly attached waist edge, and affixed in front of the base flat surface. It has at least an insertion groove into which an end surface portion of the exterior material to be inserted can be inserted, and a decorative ridge located inside the insertion groove. In this case, the work of fixing the decorative member becomes easy by having the base flat surface, and the appearance design around the opening after reforming can be further enhanced by providing the decorative ridge.

[0008] In a further preferred aspect, a large number of holes for discharging rainwater are provided on the bottom surface of the insertion groove in the linear member that forms the upper side around the new opening. With this configuration, after the renovation, the rainwater that has traveled along the outer wall surface and entered the insertion groove can be reliably discharged to the outside, and the intrusion of the rainwater into the building is avoided. In addition, when the decorative member has the decorative ridge, the decorative ridge acts as a draining function part to prevent rainwater falling from the hole from flowing into the opening side and looked up from below. It can also play a role of hiding the rainwater discharge hole at the time, and further improve the appearance design of the entire opening.

The upper and lower and right and left linear members may be formed in advance to a predetermined length. However, the upper and lower linear members may be formed as long members in advance, and the opening may be newly formed. It may be obtained by cutting to an appropriate length according to the surrounding dimensions. In the case of the latter, there is an advantage that it is possible to take various construction modes with various changes for openings having different dimensions at the same or different construction sites.

[0010] In the construction method of the present invention, the above-mentioned step of fixing the decorative member around the periphery of the opening by using the torso to form a new opening, and an exterior material for renovation. The step of attaching the end face portion to the wall of the building while inserting it into the groove for insertion may be performed as separate steps before and after. Depending on the environment of the construction site, the two steps may be performed. Of course, it may be performed simultaneously.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view for explaining an embodiment of a method for constructing an opening around the opening and a decorative member around the opening used in the method according to the present invention, and FIG. 2 is a vertical view around the opening after construction. 3 is a cross-sectional view in the horizontal direction. FIG.
FIG. 4 is a perspective view showing an upper side member which is one member constituting a decorative member. In the illustrated example, the decorative member 10 around the opening according to the present invention is attached to four turns of the opening 60 of the existing building to which the window frame sash 50 is attached as an external sash, and the existing exterior is used by using the same. Wall (eg mortar wall)
A new exterior material B is attached to the outside of A to renovate the building outer wall.

In the example shown in FIGS. 2 and 3, a horizontal frame 53 and a vertical frame 54 are formed on a base material 51 and a pillar 52 of an existing building.
The exterior wall A such as a mortar wall is attached by using the waist edges 53 and 54 so as to form the existing opening 60, and a sealing material is provided around four circumferences of the opening 60. The window frame sash 50 is attached via a backup material 55 and a backup material 56. Note that the configuration around the opening is an example of the existing opening, and the construction method around the opening at the time of remodeling according to the present invention can be performed around any existing opening. It is.

At the time of construction, first, the existing opening 60 is used.
Along the four circumferences, the appropriate horizontal waist edge 3 and the vertical waist edge 4 are fixed to the exterior wall A by nailing or nails.
Next, if necessary, a coating material 6 having an L-shaped cross section so as to cover the inner end faces (cut end faces) of the fixed body edges 3 and 4.
Attach. The coating material 6 may be a steel plate or an aluminum molded product. By attaching such a covering material 6, it is possible to further enhance the water stopping property around the new opening and the appearance design. In the case where metal fittings for fixing the exterior material B using the fastening metal are performed, a spacer having an appropriate size is sandwiched between the coating material 6 and the body edge according to the metal fitting shape. Install it.

The decorative member 10 around the opening according to the present invention is attached to the body edges 3 and 4 fixed as described above. In the example shown in FIG. 1, the decorative member 10 is a linear member, which is an upper member 20, a lower member 40, a right member 41, and a left member 42, a corner member 43 bent at an angle of 90 degrees, and a straight member. And a connecting member 44 having an L-shaped cross section for connecting the side member and the corner member 43, and all the members except the connecting member 44 have the same cross-sectional shape. I have.

The details of the side members which are linear members will be described with reference to the upper side member 20 shown in FIG. 4 as an example. Upper member 20
(That is, each side member) is an extruded product of aluminum, and has a base flat surface 21 serving as a fixing surface to the newly attached body edges 3 and 4 and an exterior formed on the front side of the base flat surface 21. It has a concave groove 22 for inserting the end face portion of the material B, and a decorative ridge 23 located inside (the lower side in FIG. 4) of the concave groove 22 for insertion. The groove 22 has substantially the same width as the thickness of the exterior material B to be newly attached, and has a front surface 24 and a front surface 2.
A second decorative ridge 25 projecting forward from a lower end of the fourth decorative ridge 4, a concave groove bottom surface 26 continuous with a lower surface of the second decorative ridge 25,
And an exterior material end surface receiving base 27 located slightly above the concave groove bottom surface 26. The tip surface of the decorative ridge 23 and the second
Is flush with the tip end face of the decorative ridge 25, and
A gap 28 is formed between the decorative ridge 23 and the second decorative ridge 25. A large number of holes 29 are provided on the concave groove bottom surface 26 at predetermined intervals.

In the upper side member 20 (ie, each side member), the decorative ridges 23 and the second decorative ridges 25 are provided, their tips are flush with each other, and a gap 28 is formed between them. The formation is performed to further improve the appearance and design of the newly formed opening 60a, and the shape and size are arbitrary as long as the object is achieved. Of course, it is not limited to this. It can also be omitted.

Further, the reason why a large number of holes 29 are provided in the concave groove bottom surface 26 is that the illustrated one is the upper side member 20 and may be omitted in other side members. That is, the upper side member 20 is a member that forms the upper side when a new opening 60a is formed, and after the reforming, the rainwater flows along the outer wall surface B into the insertion groove 22 of the upper side member 20. May enter. The hole 29 is provided for discharging the rainwater that has entered, to the outside, thereby preventing the rainwater from entering the inside of the building. Further, when the decorative ridges 23 are formed, the decorative ridges 23 function as a drainer, and the holes 2
Prevents rainwater falling from 9 from flowing into the opening. Furthermore, the decorative ridges 23 can also serve to hide the rainwater discharge holes 29 when viewed from below, thereby further improving the appearance and design of the entire opening.

As described above, the lower side member 40, the right side member 41, and the left side member 42 have the same cross-sectional shape as the upper side member 20, and in this example, the presence or absence of the hole 29 formed in the concave groove bottom surface 26. Only the differences. Further, in this example, the cross-sectional shape of the corner member 43 bent at an angle of 90 degrees has the same cross-sectional shape. Therefore, each side member may be manufactured by extrusion molding, but it can also be manufactured by cutting a long aluminum extruded product having the same cross section into an appropriate length. Also, the corner member 43 bent at an angle of 90 degrees can be easily manufactured by cutting the same extruded product at an angle of 45 degrees and joining the cut surfaces so as to face each other.

As shown in FIG. 1, the connecting member 44 having an L-shaped cross section is inserted into the interior space of the decorative ridge 23 of the adjacent side member, and the ends of the connecting member 44 are not shifted. This is for stably connecting, but when the side members and the corner members are fixed to the body edges 3 and 4, they can be omitted if the positioning can be reliably performed.

The above-described upper member 20, lower member 40,
The right side member 41, the left side member 42, and the corner member 43 bent at an angle of 90 degrees are formed by the inner peripheral edges of the body edges 3 and 4 so that the respective concave grooves 22 are on the outside. By using the nail 5 around the portion, using the nailing hole 30 formed in the base flat surface 21,
And fixed. The order of the striking is arbitrary, but as described above, when the connecting tool 44 having an L-shaped cross section is used, the striking without displacement is facilitated.
By punching and fixing everything, a new opening 60a having a high water-stopping property and aesthetic design is formed.

For the newly formed opening 60a,
As shown in FIG. 1, as shown in FIG. 1, the end face portion of the new outer wall plate B for renovation is
0, right side member 41, left side member 42, corner member 43)
By sticking while inserting into the insertion groove 22, the construction around the opening at the time of reforming according to the present invention is completed. Although FIG. 1 shows a mode in which the outer wall plate B is stretched horizontally, it is needless to say that the outer wall plate B may be stretched vertically.

[0022]

As described above, according to the method of the present invention around the opening at the time of renovation, the existing outer wall can be completely concealed by attaching the new exterior material B, and the new exterior material B can be completely concealed. The end face portion of the exterior material around the opening is completely covered with the concave groove 22 of the decorative member 10 and is not exposed to the outside. for that reason,
The end face of the new exterior material B is not exposed to rainwater, there is no need for sealing work, and rainwater does not enter the interior of the building. Appearing outside around the new opening is a decorative member 10 made of an extruded aluminum product.
, And high appearance design can be easily secured.

Further, according to the present invention, the work of attaching the decorative member 10 at the time of reforming is easy, and a secure fixation is obtained. In addition, required water stoppage between the existing opening 60 and the new opening 60a is also ensured. Further, the decorative member 10 is provided with the upper and lower linear members and the right and left linear members.
Since it is configured as a set of corner members that are bent every time, it is easy and appropriate to apply various types of openings by simply changing the length of the linear member. be able to.
