Description

The present invention relates to a parting edge used for a building (including a structure), and particularly does not require high construction accuracy, and has uniform designability when used with a corner member that covers the corner in a curved shape. Regarding the parting edge for the outside corner that has a feeling and does not spoil the appearance.

At the projecting corner, which is the corner of the building, in addition to the projecting corner cover, a base drainer is provided below and a parting edge is provided above. Conventional foundation drains and parting edges have similar problems. In the following, the problem will be described by taking the base drainage as an example.
The conventional foundation draining drainage is formed at a right angle to install it at the corner of the building, and if the corner is not chamfered, there is a technology to chamfer the corner of the foundation draining of the installed building. Proposed. Japanese Patent No. 51213156 (Patent Document 1) is a foundation drainer for a corner of a building, and since the corner portion has a chamfered shape and a separate fixing member such as a rivet is not necessary, the construction is simple and Disclosed is a base drainer for the projecting corner where the upper surface of the portion has considerable strength.

The base drainage drainer for the projecting corner disclosed in Patent Document 1 is a base draining drainer for the projecting corner that is installed in a corner portion of a building and includes a base portion and a rising surface, and the base portion is a top surface, a side surface, and a bottom surface. It has a U-shaped cross-section and is cut off on both sides of the base, leaving the center overlap on the top surface of the base. When the bases on both sides are bent from the cut part, the center overlap and the top surfaces of the bases on both sides. Can be combined so that at least a part thereof overlaps, and the rising surface continuously rises upward from the upper surface of each base, and an engaging portion that engages one rising surface and the other rising surface is provided. The engagement portion is provided with an engagement overlap margin that is arranged on the central side surface of the rising surface that is continuous from the upper surface of the base that is stacked on the upper side when combining, and a rising surface that is continuous from the upper surface of the base that is stacked on the lower side. It is characterized in that it comprises a locking piece arranged on the central side surface, the locking piece is arranged above the overlap margin, and the lower end of the stopper piece and the upper end of the engagement overlap margin are engaged with each other.

According to the drainage base drainer disclosed in Patent Document 1, the corner portion of the drainage base drainage installed at the corner of the building is chamfered. Further, according to the draining base drainage, since the chamfered corners of the base are three-layered, it is possible to install the corners of the corners without using other fixtures. it can. In addition, since the corners of the corners are the top surface of the base and the center overlap, and the top surface of the base is three-layered, a high strength of the top surface of the corners of the corner can be ensured. In addition, according to the draining base drainage, three corners of the corner form an upper surface of three layers, so that the rising surface continuous from the base located at the uppermost position has a force that pushes upward, By engaging the upper end of engagement of the rising surface that is pushed up as an engaging portion of the rising surface and the lower end of the locking piece from the other rising surface, the rising surface where the locking piece is pushed is pressed down, The rise of the surface can be suppressed.

Japanese Patent No. 51213156

However, the above-explained corner drainage disclosed in Patent Document 1 has the following problems.
In the chamfered base drainer disclosed in Patent Document 1, since the left and right sides of the chamfered portion clearly appear as its linear shape in appearance, such a chamfered base drainer is accurate in the corners (corners). If it is installed high, the middle position on both the left and right sides and the position of the projecting corner match, and it looks good, but if the chamfered foundation drainer is not installed with high accuracy (position shift) However, the appearance is unfavorable because the middle position of the left and right sides does not match the position of the projected corner portion. As a result, there is a main problem that highly accurate construction is required in order to prevent such unfavorable appearance.

Further, there are the following problems as secondary problems. Such a corner draining base drainer may be provided below (as a base of) the corner protrusion member that is engaged with the siding plate provided at the corner of the building. There may be a case where a member having a decorative surface portion that covers the curved surface is used.
Even if the projecting corner member that covers the projecting corner in a curved shape is adopted to cover the projecting corner in a beautiful curved surface, if the chamfered base drainer disclosed in Patent Document 1 is adopted below the corner member, Although the upper corner is beautifully covered with a curved surface, the bottom draining part is not curved (although it is chamfered) and the design is not uniform and it may spoil the aesthetics It is highly likely.

Not only the foundation drainage but also the parting edge have these main problems and secondary problems.
The present invention was developed in view of the above-mentioned problems of the prior art, and an object thereof is to be used for a corner portion (extended corner portion) of a building (including a structure) and have high construction accuracy. It is to provide a parting edge for a projected corner that is not required, and when used with a projected corner member that covers the projected corner in a curved shape, there is a sense of unity in design and does not impair aesthetics, The purpose is to provide a parting edge for the projected corner.

In order to achieve the above object, the projected corner parting edge according to the present invention employs the following technical means.
That is, the parting edge for the projected corner according to the present invention is a partitioning part for the projecting corner that is provided at the projecting corner of the building and includes a base portion and a falling surface, and the partitioning part for the projecting corner is a flat surface. The metal plate is cut into a predetermined shape and bent to form a three-dimensional shape, and the base portion includes a curved surface portion that covers the projected corner in a curved shape.

It will be described in detail based on this. The R-shaped parting edge 100 for the projected corner is a projected corner member (projected corner) that covers a corner portion (projected corner portion) formed by abutting the ends of the exterior material 1300 used for a building (including a building) in a curved shape. R-shaped projected corner cover 1100 with a curved decorative surface portion 1110 that covers the curved surface and a uniform feeling of design (unification of having a curved surface shape together), which does not impair aesthetics and requires high construction accuracy. It is an example of a parting edge for a projected corner that is not disassembled without being easily disassembled. The parting edge for the projected corner according to the present invention is not limited to the one used for the corner portion where the exterior material is abutted, and a projected corner member having an L-shaped cross section (rather than abutting the exterior material) is used. May be used together with this projecting corner member to form a corner portion, and is not limited to one used in combination with a projecting corner member that covers the projecting corner in a curved shape as will be described later. It may be used together with a corner member that covers a shape (for example, an L-shaped cross section). Moreover, the parting edge for the projected corner according to the present invention is not limited to exterior (outdoor) applications, and may be used (with the R-shaped projected corner cover 1100 or with another projected corner cover) such as a tenant in a shopping mall. It may be used indoors.

First, referring to FIG. 1 and FIG. 2, the R-shaped parting edge 100 for the projected corner and the R-shaped projected-corner cover 1100 constructed by being suitably combined with the R-shaped parting edge 100 for the projected corner to be installed. (Construction state) will be described. Note that, in the following, as an example of a projected corner member that covers a corner portion (projected corner portion) formed by abutting longitudinal end portions of an exterior material 1300 used for a building (including a structure) in a curved shape, a projected corner The R-shaped projected corner cover 1100 having the curved decorative surface portion 1110 that covers the curved surface is merely described, and the projected corner parting edge according to the present invention is limited to the R-shaped projected corner cover 1100 and combined. However, the present invention is not limited thereto, but is not limited thereto, and the cutout edge for the projected corner according to the present invention is preferably combined with the R-shaped projected corner cover 1100 as described above.

The R-shaped parting edge 100 for the projected corner is vertically above the R-shaped projected corner cover 1100 provided with the curved surface 1110 that covers the projected corner in a curved shape as described above (though not limited thereto). It is an example of the parting edge for the projected corner that is constructed as a parting edge and has a curved design, which has a unified design and does not spoil the appearance of the projected corner and is difficult to disassemble. Therefore, the R-shaped projected-corner cover 1100 constructed together with the R-shaped parting edge 100 for the projected corner will be described first.

The R-shaped projected corner cover 1100 is engaged and fixed to a siding plate 1200 of a corner portion (exposed corner portion) formed by abutting the longitudinal ends of the exterior material 1300. The plywood plate 1200 is fixed to a corner column 1500, which is a wall base, by a fastening member 1404 (or a fastening member 1412) such as a tapping screw via a furring strip 1400 (or furring strip 1410). Further, the furring strip 1400 (or the furring strip 1410) is fixed to the corner column 1500 by a fastening member 1402 (or a fastening member 1414) such as a tapping screw. In addition, it is also preferable that a waterproof member such as a sponge is continuously provided in the vertical direction in a circular region shown by a dotted line in FIG. Here, the attachment method (fixing method) of the pouch board 1200 in the housed state of the R-shaped projected corner cover 1100 shown in FIG. 2A is not limited to the above-described method, and for example, the furring strip 1400 ( Alternatively, a method may be used in which the siding plate 1200 is directly fixed to the corner strut 1500 without using the furring strip 1410).

Here, the R-shaped projected corner cover 1100 (decorative surface portion 1110 and the two engaging portions 1120) and the siding plate 1200 are thin metal plates, for example, iron, aluminum, copper, stainless steel, titanium, aluminum-zinc alloy plating. Steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (vibration suppression steel plate, etc.), etc. (including metal color plates coated with these in various colors), or synthetic resin plate material, For example, one type of vinyl chloride resin, polycarbonate resin, etc. (including synthetic resin color plates coated with these in various colors) is molded into various shapes by roll molding, press molding, extrusion molding, notch processing, etc. ..

The pouch board 1200 is a long plate material, and as shown in FIGS. 2(A) and 2(B), at least fits (which can be engaged with the engaging portion 1120 of the R-shaped projected corner cover 1100). It is formed by including the joint portion 1210. More specifically, as shown in FIGS. 2A and 2B, the fitting portion 1210 accommodates the engaging claw 1132 in which the pair of leg portions 1128 of the engaging portion 1120 is folded back by the claw folding portion 1130. A space 1210C is provided. Further, the fitting portion 1210 guides the engagement claw 1132 into the space 1210C promptly (in the direction indicated by the white arrow in FIG. 2B), and from the space 1210C. A return portion 1210B is provided to prevent the engaging claw 1132 from separating from the space 1210C by contacting the open tip of the engaging claw 1132 when the engaging claw 1132 tries to separate. Here, the shape of the siding plate 1200 shown in FIGS. 2A and 2B is not limited to the above-described shape.

The surface (outdoor side) of the decorative surface portion 1110 is appropriately determined according to the design of the decorative surface and the shape of the cross section of the exterior material 1300, and when a wall body is formed using the exterior material 1300 as shown in FIG. The decorative surface portion 1110 shown in FIG. On the back surface of the decorative surface portion 1110, a double portion 1114 obtained by folding the decorative surface portion 1110 at the double folding portion 1112 and an end portion 1122 of the engaging portion 1120 (as indicated by a chain double-dashed line in FIG. 2B). ) By being inserted, the decorative surface portion 1110 and the engaging portion 1120 formed of separate members are joined.

It should be noted that the R-shaped projected corner cover 1100 is used in the vertical direction as shown in FIG. 1 or without being connected. In this case, although not limited, for example, the shape of the upper and lower ends in the vertical direction is formed separately from the male part and the female part, and the male part is inserted into the female part (the male part is The male part is overlapped with the female part so that it cannot be seen from the outside. In this case, after the engaging portion 1120 of the R-shaped corner cover 1100 is engaged with the fitting portion 1210 of the plaid board 1200, the male portion is inserted into the female portion and two or more continuous in the vertical direction. The R-shaped projected corner cover 1100 is connected.

The R-shaped projecting corner cover 1100 is a building exterior projecting corner member that is engaged with a table board 1200 provided in a projecting corner of the building, and the table board 1200 projects to the outdoor side and is continuous in the vertical direction. The fitting portion 1210 is provided. The R-shaped projected corner cover 1100 includes a decorative surface portion 1110 that covers the projected corner in a curved shape, and an engaging portion 1120 that is engaged with the fitting portion 1210. The engaging portion 1120 engages with the fitting portion 1210. The opposite side (the bent portion 1126) of the side to be contacted is in contact with the back surface 1116 of the decorative surface portion 1110. Therefore, the effect of increasing the strength of the curved surface portion of the decorative surface portion 1110 can be exhibited. As a result, even if a hard object hits the curved surface portion of the decorative surface portion 1110 and an impact is applied, the curved surface portion of the decorative surface portion 1110 can be prevented from being dented and deformed.

Further, in the engaging portion 1120, the opposite side (bending portion 1126) of the side that engages with the fitting portion 1210 is continuously in contact with the back surface 1116 of the decorative surface portion 1110 in the vertical direction. For example, when the back surface 1116 of the decorative surface portion 1110 is a flat surface, the opposite side (bent portion 1126) of the engaging portion 1120 that engages with the fitting portion 1210 is continuously abutted in the vertical direction. If the back surface 1116 of the decorative surface portion 1110 is not a flat surface (for example, the design of the uneven shape of the surface of the decorative surface portion 1110 appears on the back surface and is not a flat surface), the opposite side of the engaging portion 1120 that engages with the fitting portion 1210. The (bent portion 1126) is abutted discontinuously in the vertical direction. In addition, when the design of the uneven shape of the surface of the decorative surface portion 1110 also appears on the back surface and is not flat, it means that the design is not continuous (discontinuous) in the concave portion (only) when viewed microscopically. Since it cannot be said that 1126 is in contact with each other, it is merely an indication that it is not continuous. Therefore, even if the design of the uneven surface on the surface of the decorative surface portion 1110 appears on the back surface and is not flat, the effect of increasing the strength of the curved surface portion of the surface of the decorative surface portion 1110 is exhibited.

Further, in the engaging portion 1120, the side opposite to the side engaging with the fitting portion 1210 (bent portion 1126) is in linear contact with the substantially central portion of the back surface 1116 of the decorative surface portion 1110 in the vertical direction. For example, as shown in FIG. 2B, the opposite side (bent portion 1126) of the engaging portion 1120 that engages with the fitting portion 1210 is vertically linear at approximately the center of the back surface 1116 of the decorative surface portion 1110. Is in contact with.

Further, the engaging portion 1120 is provided with a pair of leg portions 1128 having a symmetrical shape in a horizontal plane view, and in the leg portions 1128, the side opposite to the side engaging with the fitting portion 1210 (bending portion 1126) is a makeup. The shape is such that it comes into contact with the back surface 1116 of the surface portion 1110 and the distance between the pair of leg portions 1128 increases from the opposite side (bent portion 1126) toward the fitting portion 1210 side. For example, as shown in FIG. 2B, the distance D(1)<the distance D(2)<the distance D(3).

Further, the line of symmetry of the pair of legs 1128 and the substantially center line of the curved surface shape of the decorative surface portion 1110 coincide with each other. As shown by the alternate long and short dash line in FIG. 2B, the symmetry line of the leg portion 1128 and the substantially center line of the curved surface shape of the decorative surface portion 1110 coincide with each other.
Further, the decorative surface portion 1110 and the engaging portion 1120 are formed as separate members, and the decorative surface portion 1110 and the engaging portion 1120 are joined. The R-shaped projected corner cover 1100 is formed of one decorative surface portion 1110 and two engaging portions 1120. For this reason, the R-shaped projected corner cover 1100 is different from a decorative cap or the like formed by bending one member intricately, if one decorative surface portion 1100 and two engaging portions 1120 having a simple structure are joined together. It is preferable because it is good and can be easily manufactured. More specifically, as shown in FIG. 2B, the decorative surface portion 1110 is formed by inserting the end 1122 of the engaging portion 1120 into the double portion 1114 obtained by folding the decorative surface portion 1110 at the double folding portion 1112. The engaging portion 1120 and the engaging portion 1120 are formed as separate members and are joined together. The method of joining the decorative surface portion 1110 and the engaging portion 1120 is not limited, but it is preferable to firmly join them by, for example, rivets.

Here, the shape of the R-shaped projected corner cover 1100 shown in FIGS. 1, 2A, and 2B is limited to the above-described shape except that the R-shaped projected corner cover 1100 has a decorative surface portion 1110 that covers the projected corner in a curved shape. Not something.
Next, the outline of the characteristic structure of the projected corner R-shaped parting edge 100 according to the present embodiment will be described. The vertical direction and the horizontal plane are the directions and planes shown in FIG. Further, the R-shaped parting edge 100 for the projected corner is shown in FIGS. 3(A) and 4(A).
In the plan view shown in FIG. 2, since it has a left-right substantially symmetrical shape in which a center line L described later is line-symmetrical, the following description will be valid even if the left-right is reversed, and the left-right direction and the vertical direction are not limited. I may explain. The left-right substantially symmetrical shape of the R-shaped parting edge 100 for the projected corner has a left-right substantially symmetrical shape with respect to the entire shape on both the front surface side (FIG. 3A) and the rear surface side (FIG. 4A). However, as will be described later, the boundary lines (the boundary first bonding line 324 and the boundary second bonding line 354) between the left base plane 310 and the right base plane 350 are not limited to this.

The R-shaped parting edge 100 for the projecting corner is provided as a parting edge in the projecting corner of the building, as shown in FIGS. 1 and 2 described above. As shown in FIGS. 1 to 5, the projected corner R-shaped parting edge 100 generally includes a base portion 300 and a falling surface 200. The R-shaped parting edge 100 for the projected corner is obtained by cutting a flat metal plate (typically a metal steel plate) into a predetermined shape as shown in the development view of FIG. 5 and bending it as shown in FIG. The three-dimensional shape shown in FIGS. 1, 3 and 4 is formed. The base portion 300 includes a curved surface portion 480 that covers the projected corner in a curved shape.

Further, the curved surface portion 480 is formed in a band shape as shown in FIGS.
More preferably, the falling surface 200 includes a left side surface 210 and a right side surface 250 located at a substantially right angle (the substantially right angle is the angle in plan view shown in the horizontal plane) from the left side surface 210.
The base part 300 is bent from the left side face 210 or the right side face 250 at a substantially right angle (this substantially right angle is an angle in a side view shown in a vertical plane) and is continuous to form a base plane (continuous from the left side face 210). The right base plane 350 continuous from the left base plane 310 and the right side surface 250) and the left side surface 210 or the right side surface 250 are substantially parallel to each other (relationship of planes substantially parallel to each other in space) and are substantially perpendicular to the base plane. (This substantially right angle is an angle in a side view shown in a vertical plane) and is continuous with the base side surface (the left base side surface 410 continuous with the left base plane 310 and the right base plane 350 with continuous) Right base side surface 450).

Further, the base plane includes a left base plane 310 which is bent from the left side surface 210 at a substantially right angle and is continuous, and a right base plane 350 which is bent at a substantially right angle from the right side surface 250 and is continuous. The pedestal side surface is substantially parallel to the left side surface 210 and is continuous from the left pedestal plane surface 310 by being bent at a right angle, and the left pedestal side surface 410 is substantially parallel to the right side surface 250 and the right pedestal plane surface 350. Includes a right base side surface 450 which is bent at a substantially right angle from and is continuous, and a curved surface portion 480. Then, on the side surface of the base, it is formed continuously from the side surface 410 on the left side to the side surface 450 on the right side via the strip-shaped curved surface portion 480.

Further, as shown in FIGS. 1 and 3A, on the base planes (the left base plane 310 and the right base plane 350), the boundary line between the left base plane 310 and the right base plane 350 ( The first boundary line 324 and the second boundary line 354) do not coincide with the center line L drawn from the intersection X between the upper end of the left side surface 210 and the upper end of the right side surface 250 to the farthest position Y of the curved surface portion 480. .. This is a boundary line between the left base plane 310 and the right base plane 350 on the base plane, and a virtual extension line of the left base side surface 410 in a plan view from the intersection of the left side surface 210 and the right side surface 250. This means that the center line L drawn to the intersection with the virtual extension line of the right base side surface 450 does not match. In this way, since the boundaries of the base planes (the left base plane 310 and the right base plane 350) are not arranged on the center line L, the flat metal steel plate is bent to form a three-dimensional shape. It is possible to prevent the R-shaped parting edge 100 for the projected corner from being easily disassembled (which makes it impossible to maintain the three-dimensional shape). That is, since there is no boundary line at the substantially symmetrical position (on the center line L) of the R-shaped parting edge 100 for the projected corner, which has a substantially symmetrical shape, either the left or right side of the R-shaped parting edge 100 for the projected corner. Even if a force (in the direction of separating the left base plane 310 and the right base plane 350) enough to disassemble the R-shaped parting edge 100 for the projected corner is applied to (or both sides), the action of this force is exerted. The direction in which the left base plane 310 and the direction in which the left base plane 310 and the right base plane 350 are separated do not coincide with each other, so that the R-shaped parting edge 100 for the projected corner is easily disassembled (the three-dimensional shape cannot be maintained. Can be avoided.

Further, the left side surface 210 and the right side surface 250 are, as shown in FIG. 3(B), FIG. 4(B) and FIG. 5, a falling overlap that engages with each other inside the R-shaped parting edge 100 for the projected corner.
