The joint cover C is arranged at the joint B of the first embodiment, and the gap D formed between the cover A and the seam cover C is sealed so that the joint B can be provided with waterproofness.

Kasagi A is made of an extruded product of aluminum, and has a cross section formed in a substantially U-shape having a top plate 1 and a pair of legs 2 formed from both ends of the top plate 1. It is formed in a long shape having the following dimensions.

As shown in FIG. 5, the skirting A is attached to the upper end surface of the waist wall 21 over its entire length to protect the upper end portion of the waist wall 21 and improve the appearance. For this reason, although Kasagi A is formed in a substantially U-shaped cross section,
The shape and dimensions of the details are not uniquely set,
A plurality of types are employed from the viewpoint of design and practicality.

First, referring to FIGS. 4 and 5, a description will be given of a typical structure in which a coping A is attached to the waist wall 1 and connected in the longitudinal direction to form a seam B.

In the figure, a waist wall 21 is provided around a veranda or a rooftop space, and can have various structures such as reinforced concrete and wooden mortar. Uses an ALC panel (lightweight cellular concrete panel).

A plurality of head connecting members 22 are fixed to the upper end surface of the waist wall 21 at predetermined intervals. A groove-shaped receiving bracket 22a is fixed to the top end surface of the head connecting member 22, and a groove-shaped mounting bracket 23 is further bolted to the receiving bracket 22a.
Secured by 24. And Kasagi A to the mounting bracket 23
A support bracket 25a having a support piece 25a for abutting against and supporting the back surface of the top plate 1 of the cap A in accordance with the cross-sectional shape of the cap and a locking piece 25b for engaging and locking with the leg 2 are fixed by bolts 24. It is fixed.

When a plurality of caps A are mounted in series on the upper end surface of the waist wall 21, the joiner is positioned at the joint of the caps A.
26 are provided. The joiner 26 is fixed to the head connecting material 22 by bolts 24, and is configured to be able to maintain the strength of the cap A by contacting and supporting the back surface of the end of the cap A. For this reason, Joiner 26 has Kasagi A
A plurality of fins 26a are formed so as to be able to come into contact with each other in a direction crossing the cross section and over substantially the entire circumference of the inner surface of the coping A.

Therefore, the core is adjusted and fixed to the upper end surface of the waist wall 21 through a plurality of sash brackets 25, and the sash A is put on the sash bracket 25 and pressed.
By engaging the locking pieces 3 formed at the distal end of the top piece with the locking pieces 25b of the coping bracket 25, the back side of the top plate 1 of the coping A can be supported by the supporting pieces 25a and firmly attached. is there.

The ends of a pair of caps A arranged in series are opposed to each other with an interval of about 10 mm without being in close contact with each other, and the back of each cap A is joined to a joiner 26.
, A seam B lined with the joiner 26 and having a predetermined gap is formed.

As shown in FIGS. 1 and 2, a seam cover C shown in FIG. 3 is disposed above the seam B and the upper end including the ends of the caps A on both sides of the seam B. The seam cover C has a cross-sectional shape substantially similar to the cross-sectional shape of the heddle A, and has an inner dimension sufficiently larger than the outer dimension of the heddle A. Further, the dimension in the same direction as the longitudinal direction of the skirting A (hereinafter referred to as “longitudinal direction”) has a length (about 40 mm) that can include the seam B and the ends of the skirting A on both sides of the seam B. ing.

Therefore, the seam cover C is made of the top plate 1 of Kasagi A.
A top plate 11 opposed to the leg 2, a leg 12 opposed to the leg 2, and a locking claw 13 formed at the tip of the leg 12 and engaged with and locked to the stepped portion 4 formed on the side surface of the cap A. It has a substantially U-shaped cross-sectional shape.

The locking claws 13 may be formed over the entire length of the joint cover C. However, in the seam cover C according to the present embodiment, the locking claws 13 are formed at both ends in the longitudinal direction. For this reason, for example, even when there is a step between the pair of caps A, it is possible to reliably engage the locking claw 13 with the step 4 of the cap A.

The seam cover C can be formed by bending a metal plate. However, in the present embodiment, a long shape material extruded from aluminum is cut to a predetermined length, and a part of the leg 12 is partially cut to form a locking claw.
The joint cover C is formed by forming 13.

As described above, the inner dimensions of the joint cover C are sufficiently larger than the outer dimensions of the coping A. For this reason, the seam cover C is disposed at the end of the seam B and the end of the heddle A, and the seam cover C is put on the heddle A and pressed, so that the locking claws 13
The seam cover C cannot maintain the position even when the seam cover C is engaged with the step portion 4. That is, it is necessary to apply a force between the cap A and the seam cover C to strengthen the engagement between them.

For this reason, an elastic body 5 having elasticity is disposed at a position facing the seam B, and the elastic body 5 urges the seam cover C in a direction away from the coping A to be locked. Engagement of the pawl 13 with the step portion 4 is strengthened.

The cross section of the elastic body 5 is formed in a U-shape from an elastic synthetic resin such as urethane foam. The thickness of the elastic body 5 is formed so as to be larger than a predetermined dimension between the outer surface of the coping A and the inner surface of the joint cover C.

As described above, by disposing the elastic body 5 at the joint B and urging the joint cover C, a gap D is formed between the outer surface of the cover A and the inner surface of the joint cover C. This gap D
Should not leak from For this reason, the gap D is filled with the water-stopping material 6 and the gap D is closed, thereby providing watertightness.

Next, a procedure for constructing the joint structure will be described with reference to FIG.

First, as shown in FIG. 1A, a masking tape 31 is attached to both sides of a seam B formed by a skirting A attached to the upper end surface of the waist wall 21. The masking tape 31 prevents the water-stopping material from adhering to other parts of the cover A when the water-stopping material is filled in a later step.

Next, as shown in FIG.
The elastic body 5 is placed on the upper part of. At this time, it is preferable that a primer is simultaneously applied to the outer surfaces of the top plate 1 and the legs 2 of the cover A defined by the masking tape 31.

As described above, the masking tape 31 is attached to the caps A on both sides of the joint B, and the elastic member 5 is attached to the joint B.
, The seam cover C is attached. The procedure for attaching the seam cover C is as follows: as shown in FIG. 3C, a waterproof material 14 such as rubber is arranged in advance at the tip of the leg 12 and held near the locking claw 13. The engaging claw 13 provided on the leg 12 is engaged with the step 4 of the skirting A, and the other limb 12 is opened and adjusted to straddle the skirting A. In this state, the seam cover C is pressed and pushed. Thus, it is possible to engage the engaging claw 13 of the other leg 12 with the stepped portion 4 of the coping A for engagement.

As described above, the locking claw 13 is attached to the step 4 of the skirting A.
The seam cover C is locked by engaging the elastic member 5 with a force in a direction in which the locking claw 13 is engaged with the step portion 4 by the elastic force of the elastic body 5, thereby realizing a strong engagement. Is possible. Then, a gap D is formed between the outer surface of the cover A and the inner surface of the joint cover C, as shown in FIG.

Next, as shown in FIG. 4E, a gap D formed between the outer surface of the cover A and the inner surface of the seam cover C is filled with the water stopping material 6. This operation is no different from the usual operation of filling the waterproof material.

After the water blocking material 6 has been filled in the gap D formed between the cover A and the seam cover C as described above, the masking tape 31 adhered to the cover A as shown in FIG. By peeling off, seam B of Kasagi A becomes seam cover C
The completed seam structure is completed.

[0035]

As described in detail above, in the joint structure according to the present invention, the seam cover attached to the waist wall is covered with the joint cover, and the gap formed between the two is filled with the waterproof material. The seam can be made waterproof.
For this reason, there is no need to construct a waterproof layer under the skirting tree,
Construction can be carried out without the need for waterproofing. Therefore, it is possible to reduce the number of processes by one, which facilitates the adjustment of the work setup and shortens the number of construction days. In particular, when the waterproof material deteriorates, repair can be easily performed.

Further, since the joint is covered with a joint cover at the seam, the seam can be extremely easily installed after the seam is attached to the upper end surface of the waist wall. For this reason, for example, it is advantageous when it is applied at the time of renovation when the waterproof performance of the cap is deteriorated by using the building for a long period of time, repair or repair of occurrence of water leakage or fear of water leakage.

Further, since the water-stopping material is filled independently between each of the caps and the seam cover located on both sides of the seam, it is possible to prevent an excessive breaking stress from acting on each water-stopping material. I can do it. Therefore, the life of the joint structure can be extended.

In particular, in the conventional seam, the waterproof material provided for waterproofing deteriorates with time or becomes dirty, but such an anxiety is prevented by covering the upper part of the seam with the seam cover. I can do it.
