DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap that has a fan shape or an S-shape when mounted on a parapet or the like on a building roof.

[0002]

2. Description of the Related Art It is generally known that a cover attached to a parapet on the roof of a building has a downward U-shaped cross section formed by a top plate and two side plates.

[0003] When it is desired to make the corners of the caps attached to the parapet or the like on the roof of the building round, the caps have a fan-shaped planar shape (hereinafter referred to as fan-shaped caps).
Is used. Since the fan-shaped cap is curved, it is difficult to integrally extrude the cap, and since it has a downward U-shape, it is also difficult to press-mold a straight cap.

[0004] For this reason, as a fan-shaped cover, for example, as disclosed in Japanese Utility Model Publication No. 3-28661,
The cap is composed of a top plate made of a fan-shaped flat plate, and two side plates curved along the curve of the top plate, and the top plate is welded to a locking portion integrally provided on the two side plates. Kasagi is known in which a top plate and two side plates are joined together.

Further, as disclosed in Japanese Utility Model Laid-Open Publication No. 3-35127, an adhesive which comprises a top plate and two side plates and which is bent at right angles to the side plates at the upper edge of each side plate. Kasagi is formed by continuously forming the surface in the longitudinal direction of the side plate, applying an adhesive to the bonding surface, positioning the side edge of the top plate on the top surface, and joining the top plate and the two side plates. It has been known.

[0006]

In the case of the former fan-shaped cap, since the top plate and the side plate are welded inside the cap, the welding traces do not appear on the cap and the appearance of the cap is beautiful. It does not impair, and the assembly strength of the coping will be strong

However, it is necessary to prevent rainwater or the like from penetrating from the joint between the top plate and the side plate in the fan-shaped cover, and in the case of the former fan-shaped cover, the entire length of the top plate and the side plate is required. Welding without any gaps, the heat generated during welding causes distortion in the top plate and side plates, resulting in distortion of the fan-shaped cap, resulting in a poor-looking cap. Further, it is difficult to weld the long side plate and the top plate over the entire length without any gap, and it is difficult to reliably prevent rainwater or the like from entering the joint between the top plate and the side plate.

In the case of the former cap, it is also possible to bond the top board and the side boards by bonding, so that no distortion occurs in the cap, but since the bonding area is small, sufficient bonding strength is obtained. And the connection strength between the top plate and the two side plates is weakened.

[0009] On the other hand, the latter fan-shaped coping can provide a certain degree of bonding strength due to the large bonding area. However, the bonding using an adhesive has the following problems.

[0010] That is, bonding with an adhesive is greatly affected by the amount of the adhesive, and in adjusting the amount, it is extremely troublesome to continuously apply a fixed amount of the adhesive to the bonding surface. And it was not good workability. If the amount of the adhesive is too small, a gap is formed between the members of the top plate and the side plate, and the watertightness is lost, so that rainwater or the like infiltrates. Overflowed and was exposed to the outside of the Kasagi, degrading the aesthetic appearance.

Furthermore, the joining by the adhesive has a weaker joining strength than the welding, the connection between the top plate and the side plate is very unstable, and the assembling strength of the coping is weak and easy to separate. When an external force was applied to the side plate, the side plate sometimes tilted toward the inside of the coping.

[0012] In addition, when the former fan-shaped coping and the latter fan-shaped coping are used, when the top plate and the two side plates are connected to each other, two pieces are required.
Since the two side plates are positioned and held and joined by welding or an adhesive, the assembling work is very troublesome.

According to the building edge material disclosed in Japanese Utility Model Publication No. Sho 62-10344, a holding rod is interposed between both side plates so that the distance between the both side plates is constant at any position. Although the positioning of the side plates is performed by the holding rods, the holding rods determine the distance between the side plates and do not improve the connection strength.

Accordingly, an object of the present invention is to provide a fan-shaped cap that can solve the above-mentioned problem.

[0015]

According to the present invention, a sash is provided by connecting a curved flat top plate 1 and two side plates 2 curved along the curved side edges of the top plate 1. The facing surface 5 of the two side plates 2 is provided in a substantially downward facing U-shape.
A protrusion 6 is provided integrally on the upper edge side over the entire length in the longitudinal direction, and the upper surface of the protrusion 6 is used as an adhesive surface 7.
An adhesive 9 is applied to both sides of the top plate 1 and bonded to the bonding surface 7 of the projection 6 by bonding, and a bonding portion between the projection 6 and the top plate 1 or a portion continuous with the bonding portion. A concave groove 8 is formed in the longitudinal direction so that excess adhesive 9 accumulates in the concave groove 8, and the reinforcing material 3 is joined between the two side plates 2 to join the top plate 1 and the two The side plates 2 are connected.

[0016]

[Operation] By joining the top plate 1 and the side plate 2 with the adhesive 9, the cap is not distorted by the heat of welding, so that the cap has a beautiful appearance. When the bonding surface 7 of the projection 6 and the top plate 1 are bonded, an extra adhesive 9
Accumulates in the groove 8, and the excess adhesive 9 is applied to the top plate 1 and the side plate 2.
It does not overflow from the joint part of, and the joint trace is not seen on the surface of the cap, resulting in a beautiful appearance of the cap. The adhesive layer between the top plate 1 and the protrusion 6 increases, and the top plate 1 and the protrusion 6 There is no gap without the adhesive 9 between them, so that rainwater does not enter into the cap, and the watertightness is improved. In addition, since the reinforcing member 3 is joined between the two side plates 2, the interval between the two side plates 2 can be determined, so that the top plate 1 can be easily joined and the assembling workability is improved, and the connection strength between the two side plates 2 is improved. Is increased by the reinforcing material 3, so that the assembling strength of the casket is sufficiently high regardless of the bonding of the top plate 1 and the two side plates 2 with an adhesive, and the side plates 2 fall down inward or 1 and the side plate 2 are not decomposed.

[0017]

[Embodiment] FIG. 1 is an exploded perspective view of a shed tree according to the present invention. This cap is curved in a fan shape in plan view. For example, when the cap is attached to a peripheral wall on a building roof, it is used for a curved portion of the peripheral wall, particularly a corner portion. The cap is composed of a top plate 1 and two side plates 2, and the top plate 1 and the side plates 2 are joined with an adhesive over the entire length in the longitudinal direction, and a reinforcing material 3 is provided between the two side plates 2 in the longitudinal direction. Arrange multiple
By joining the two side plates 2 and the respective connecting members 3 by welding, a coping having a downward U-shaped cross section and a planar shape curved in a fan shape is assembled.

The top plate 1 is a flat plate whose plane shape is curved in a fan shape, and the plane shape of both side surfaces 4 of the top plate 1 is arcuate along the longitudinal direction, so that both side edges of the top plate 1 are formed. Has a planar shape curved in an arc along the longitudinal direction.

The two side plates 2 have the same curvature as the side surface 4 of the top plate 1 and the plane shape is curved in an arc shape along the longitudinal direction. 6
Are provided integrally over the entire length in the longitudinal direction.

The projection 6 projects in a direction perpendicular to the side plate 2, and the upper surface of the projection 6 serves as an adhesive surface 7. It is formed over. The projecting portion 6 may have notched grooves spaced apart in the longitudinal direction so that the side plate 2 is easily curved in an arc shape.

The reinforcing member 3 is in the form of a thin plate, and the portions near both ends in the longitudinal direction are joined to the lower portions of the protrusions 6 of the two side plates 2 by welding. By welding the reinforcing member 3, the two side plates 2 are joined. They are positioned and connected at predetermined intervals.

FIG. 2 is a longitudinal sectional view of the coping after assembling by joining the top plate 1 to two side plates 2 connected by a reinforcing member 3. The reinforcing member 3 is located on the lower surface of the protrusion 6, and the reinforcing member 3
Are in contact with the opposing surfaces 5 of the side plates 2, respectively. The reinforcing member 3 is joined by welding at the tip of the projection 6.

As described above, the longitudinal end face 3a of the reinforcing member 3
Abuts against the opposing surface 5 of each side plate 2 so that the two side plates 2
Can be positioned and connected at predetermined intervals, and the top plate 1 can be easily joined, so that the assembling work is simplified.

The top plate 1 has both side edges arranged over the upper surfaces of the protrusions 6 of the two side plates 2, and is bonded to the bonding surface 7 of the protrusion 6 with an adhesive 9.

The adhesive 9 is filled in advance in the concave groove 8 of the projection 6, and by pressing both side edges of the top plate 1 against the bonding surface 7 of the projection 6, the adhesive 9 is attached to the side plate 2 and the top plate 1. (Between the lower surface of both sides of the top 1 and the upper surface of the projection 6 and the top 1
The excess adhesive 9 is returned into the concave groove 8 so that the adhesive 9 does not flow out evenly between the both side surfaces 4 and the side plate 4 facing surface 5), and does not overflow from the joint, and more joint 9 The adhesive 9 is interposed in layers to improve the watertightness of the joint.

That is, in order to fill the gap generated at the joint between the top plate 1 and the side plate 2 and to prevent rainwater or the like from entering the inside,
It is necessary to evenly fill the joints with the adhesive 9. If the amount of the adhesive 9 to be applied to the bonding surface 7 is too small, a gap is formed in a joint portion between the two members, and the joining becomes unstable. If the amount of the adhesive 9 is too large, the adhesive 9 overflows from the joint portion of the two members, and the adhesive 9 is exposed to the outside of the heddle, thereby deteriorating the appearance of the heddle. From this,
A groove 8 is formed so that the adhesive 9 spreads evenly over the entire joint portion of the two members, and the excess adhesive 9 is returned into the groove 8 so that the adhesive 9 does not overflow from the joint portion. By interposing more adhesive layers between the members, the watertightness of the joint is improved.

The top plate 1 and the side plate 2 are joined by an adhesive 9 so as not to cause distortion of the coping. However, the joining by the adhesive 9 does not have durability and sufficient strength. However, the connection strength between the top plate 1 and the two side plates 2 is weak. For example, when an external force is applied to the side plate 2 from the side, the side plate 2 is likely to be inclined inward of the kasagi, and the top plate 1 and the side plate 9 may be separated again.

In order to prevent this, two side plates 2
Reinforcing members 3 are joined in between to increase the assembly strength of the coping so that the side plates 2 do not tilt or the top plate 1 and the side plates 2 do not disassemble.

In the above embodiment, the concave groove 8 is formed on the bonding surface 7; however, it may be formed on the bonding surface of the top plate 1 as shown in FIG. 3, or the opposing side plate 2 may be formed as shown in FIG. It may be formed at a portion of the surface 5 that is continuous with the bonding surface 7. In other words, the concave groove 8 may be formed at the bonding portion between the protrusion 6 and the top plate 1 or at the portion where the protrusion 6 is connected.

Further, as shown in FIG.
L-shaped protrusions 20 are integrally provided to form upward concave portions 21, and reinforcing members 3 are formed in a downward U-shape to form hanging pieces 3 on both sides.
b is in contact with the facing surface 5 of the side plate 2 and is fitted into the upward recess 21.

In this manner, the area of the contact portion between the reinforcing member 3 and the side plate 2 increases, and it becomes easy to set the posture of the side plate 2 at the time of welding to a correct position. In addition, reinforcement material 3
And the side plate are fixed by the fitting portion of the hanging piece 3b and the upward concave portion 21, so that when a moment is generated on the end side of the reinforcing member 3 toward the inward side of the kasagi by welding, the moment is converted into the above-mentioned moment. And the reinforcing member 3 and the side plate 2 are firmly fixed by the above-mentioned fitting portion, so that the inward tilting of the side plate 2 can be prevented more reliably.

Also, as shown in FIG. 6, an upward piece 3c is provided on the reinforcing member 3, and a downward concave portion 22 is formed in the projection 6, and the upward piece 3c is fitted into the downward concave portion 22. . The upward piece 3c is formed by embossing a part of the reinforcing material.

In this manner, since the pair of side plates 2 can be temporarily assembled and connected by the reinforcing members 3, the joining of the top plate 1 and the joining of the reinforcing members 3 can be facilitated.

Further, as shown in FIG.
And the downward piece 3b of the reinforcing member 3 is welded to the projecting piece 23.

In this way, the upper and lower portions of the reinforcing member 3 are fixed to the side plate 2 and the reinforcing member 3 and the side plate 2 are firmly fixed, so that the inward inclination of the side plate 2 is further ensured. Can be prevented.

In the above embodiment, the reinforcing member 3 is joined to the side plate 2 by welding. Thus, when joined by welding,
Although the side plate 2 may be distorted by the heat generated at the time of welding, it is not preferable. However, this is a case where the entire joint portion between the top plate 1 and the side plate 2 is welded, and is used for joining only the reinforcing member 3. If so, the amount of the welded portion is small and there is no such thing as to distort the side plate 2.

However, there is another problem in welding, and the member may be burned by the welding, and the member may be discolored. For example, performing welding directly on the back surface of the side plate and the top plate causes burns on the side plate and the top plate and causes discoloration on the surface of the side plate top plate.

In the above embodiment, in order to prevent discoloration due to the above-mentioned welding, it is assumed that welding of the reinforcing member 3 is not performed directly on the back surfaces of the top plate 1 and the side plate 2,
As shown in FIGS. 2 and 7, welding is performed between the tip of the protrusion 6 formed on the side plate 2, the tip of the protrusion 23, and the reinforcing member 3,
The welding part is located at a position away from the back surface of the top plate 1 and the side plate 2,
The effect of the burn of the member is prevented from affecting the surfaces of the side plate 2 and the top plate 1.

Next, another embodiment of the present invention will be described. FIG.
Shows a modification of the arrangement of the reinforcing members 3. The reinforcing member 3 is bent downward at both ends in the longitudinal direction so as to have a downward piece 3b, and the reinforcing member 3 is arranged between the respective projecting portions 6 of each side plate 2,
Further, the projection 6 and the downward piece 3b are welded with the upper surface 3c of the reinforcing member 3 at the same height as the bonding surface 7 of the projection 6. Then, an adhesive 9 is applied to the bonding surface 7 and the reinforcing member upper surface 3d, and the top plate 1 is arranged above and bonded.

As a result, the side plate 2 has strength against external force from the side, and the bonding area of the top plate is increased, so that the bonding between the top plate 1 and the side plate 2 becomes stronger.

FIG. 9 shows a modification of the welded portion of the reinforcing member 3. A protrusion 10 is formed at a position below the protrusion 6 on the facing surface 5 of the side plate 2, and the reinforcing material 3 is provided between the protrusion 6 and the protrusion 10.
Are fitted and supported, and the projection 6 and the reinforcement 3 are welded to each other, and the projection 10 and the reinforcement 3 are welded to each other.

As a result, the reinforcing member 3 can be positioned and temporarily held before welding, and welding workability is improved. Since the welding is not performed directly on the facing surface 5 of the side plate 2, the surface of the side plate 2 is not discolored by burning, and the reinforcing member 3 is sandwiched between the protrusion 6 and the protrusion 10. Even if an external force is applied to the reinforcing member 2, the end of the reinforcing member 3 does not displace and has high strength. The welded portion of the reinforcing member 3 may be one of the projections 6 and the projection 10 instead of both.

FIG. 10 shows a further modification of the welded portion of the reinforcing member 3. Both ends of the reinforcing member 3 in the longitudinal direction are bent into an L-shape, and the ends of the reinforcing member 3 are fitted between the protrusions 6 and the protrusions 10 and welded to the protrusions 10.
c is the same height as the bonding surface 7 of the protrusion 6 and is bonded to the top plate 1 with an adhesive 9.

According to this, the positioning of the reinforcing member 3 is easy, the side plate 1 has a strong strength against external force, and the bonding surface of the top plate 1 is increased, so that the bonding between the top plate 1 and the side plate 2 is improved. It will be strong.

FIG. 11 shows a modification in which the reinforcing member 3 is fixed not by welding but by screwing. A protruding piece 11 is formed at the tip of the protruding portion 6, and the reinforcing material 3 is
Are joined.

FIG. 12 is also a modification in which the reinforcing member 3 is screwed. Both ends of the reinforcing member 3 in the longitudinal direction are bent into an L-shape, and the bent portion is fixed to the lower surface of a protrusion 11 integrally formed at the tip of the protrusion 6 with a screw 12, and the longitudinal direction of the reinforcing member 3 is changed. The center portion is made the same height as the bonding surface 7 of the protrusion 6, and the adhesive 9 is applied not only to the bonding surface 7 but also to the center of the reinforcing member 3, and the top plate 1 is also positioned at the center of the reinforcing member 3 in the longitudinal direction. Glued.

As shown in FIGS. 11 and 12, if the reinforcing member 3 is joined with the screw 12, there is no discoloration due to welding heat. 12, the bonding area of the top plate 1 is increased and the bonding strength of the top plate 1 is increased.

FIG. 13 shows a modification in which the reinforcing member 3 is joined by an adhesive. Both ends of the reinforcing member 3 in the longitudinal direction are bent into a crank shape, and the bent portion is adhered to the protruding portion 6 and the opposing surface 5 of the side plate 2 with an adhesive 9. The same height as the bonding surface 7 of the part 6,
The top plate 1 and the adhesive 9 are bonded together.

In this way, the heat generated by welding is not affected, and the entire length of the reinforcing member 3 in the longitudinal direction is bonded to the side plate facing surface 5, the projection 6, and the top plate 1, and the bonding area is reduced. Since it is large, the bonding strength is large.

As shown in FIG. 14, the reinforcing member 3 has a downward U-shape, and a protruding piece 24 is integrally provided on the facing surface 5 of the side plate 2.
The downward piece 3b of the reinforcing member 3 is brought into contact with the protruding piece 24 and is bonded to the lower surface of the protrusion 6 and the opposing surface 5 of the side plate 2 with an adhesive 9, respectively.

Further, when the bonding surface 7 of the projection 6 and the top plate 1 are bonded, the excess adhesive 9 accumulates in the concave groove 8, and the excess adhesive 9 overflows from the joint between the top plate 1 and the side plate 2. There is no bonding trace on the surface of the cover, resulting in a beautiful appearance of the cover. The bonding layer between the top plate 1 and the protrusion 6 is increased, and the adhesive 9 is provided between the top plate 1 and the protrusion 6. There is no gap without gaps, and the watertightness is improved without rainwater penetrating into the shade. In addition, since the reinforcing member 3 is joined between the two side plates 2, the interval between the two side plates 2 can be determined, so that the top plate 1 can be easily joined and the assembling workability is improved, and the connection strength between the two side plates 2 is improved.
