DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watertight structure between a vertical member and a horizontal member for securing watertightness between a cubic and a blind of a curtain wall.

[0002]

2. Description of the Related Art Since a vertical member and a horizontal member facing the outside, such as a curtain wall and a blind spot, are joined in a state where the horizontal member abuts against the side surface of the vertical member. Since rainwater falling in the swallowing groove, in which the outer wall material such as glass and panel is stored, can penetrate into the room through the gap between the end surface of the horizontal material and the water stop treatment between the two. Need to be applied.

In Japanese Utility Model Publication No. 4-20086, a block is housed in a swallow groove of a vertical member, and at the same time, a thin-walled sealer is stuck to an end face of the cross member, so that the swallow groove is formed into a swallow groove which also serves as a drainage channel. It forms a route to guide rainwater and guides rainwater to the swallowing groove side of the crosspiece while preventing rainwater from entering into the hollow part of the crosspiece and the indoor side, but it is expensive to manufacture when the block is integrated with the sealer In addition to requiring accuracy, small errors can lose the effectiveness of the seal,
Processing is difficult and costly. Further, the block is tightly fitted in the swallowing groove by being compressed by the horizontal member when the vertical member and the horizontal member are joined, but if the block is not fixed in the swallowing groove, the adhesion to the inner peripheral surface is insufficient.

[0004] The present invention has been made in view of the above background, and proposes a structure that ensures watertightness between a vertical member and a horizontal member.

[0005]

According to the present invention, the close contact between the drain block and the swallow groove is secured by fixing the drain block accommodated in the swallow groove of the vertical member to a part of the vertical member constituting the swallow groove. In addition to the securing, a filling groove is formed around the drain block, and the gap between the drain block and the swallow groove is completely closed by filling it with a wet sealing material. Prevent inward wraparound and ensure watertightness between vertical and horizontal members.

[0006] The filling groove is formed continuously on the three sides of the drain block except the side of the horizontal member along the swallow groove of the vertical member in the circumferential direction. The drain block is fixed to a part of the vertical member forming the swallow groove, and is tightly attached to the inner peripheral surface of the swallow groove by filling the filling groove with the sealing material.

When the drain block is fixed in the swallow groove, the close contact between the drain block and the inner peripheral surface of the swallow groove is enhanced.
In addition, the gap between the drain block and the inner peripheral surface of the swallow groove is completely filled by filling the sealing material along the filling groove, the water tightness around the drain block is perfect, and from around the drain block to below. Infiltration of rainwater is prevented.
Further, since the filling groove is formed continuously in the circumferential direction except for the surface on the side of the filling material, the sealing material can be filled from one side of the filling groove, and the sealing material is formed on the other side of the filling groove. Since the completion of the filling operation can be confirmed by discharging from the cross member side, it is possible to reliably fill the filling groove with the sealing material.

[0008] The upper surface of the drain block is inclined downward from the vertical member side to the horizontal member side, and guides rainwater falling in the swallow groove to the horizontal member swallow groove.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the present invention relates to a vertical member 1 having a swallow groove 11 which is open on the side of the horizontal member 2, and a swallow groove of the vertical member 1.
Swallow groove 21 with its upper surface open in the same plane as the plane containing 11
This is a structure in which the watertightness is secured by using the drain block 3 housed in the swallow groove 11 of the vertical member 1 between the horizontal members 2 having

As shown in FIGS. 2 to 4, the drain block 3 has a flat shape fitted into the swallowing groove 11 of the vertical member 1 and has a top surface.
A weir is provided on three sides of the 31 except the side of the cross member 2, and a surface surrounded by the weir is inclined downward from the side of the vertical member 1 to the side of the cross member 2. A filling groove 32 is formed along the swallowing groove 11 on the three side surfaces of the drain block 3 except the side of the cross member 2, and is continuously formed in the circumferential direction, and is fixed to the vertical member 1 at a position where the filling groove 32 is removed. Screw holes 33 are drilled. In the embodiment, since the drainage block 3 is fixed to the prospective piece 12 constituting the swallowing groove 11, the screw hole 33 is opened in the direction in which the longitudinal member 1 is found, but the drainage block 3 is fixed to the finding piece 13. In that case, it is opened in the prospect direction. In the embodiment, since the drain block 3 is formed vertically symmetrically so that it can be used for any of the left and right vertical members 1 and 1 opposed to each other with the outer wall material such as glass or panel therebetween, the filling groove 32 is formed in the screw hole 33. Sandwiching 2
Although it is formed at a location, it is sufficient that the filling groove 32 is formed at one location.

[0011] A finding piece on the indoor side constituting the swallowing groove 11
In FIG. 13, an airtight material pocket 14 for ensuring airtightness with an outer wall material housed in the swallowing groove 11 is formed facing the outdoor side. As shown in FIGS. Pocket 14
Is cut off by the length corresponding to the height at the storage position of the drain block 3 so that the continuity with the airtight material pocket 23 of the cross member 2 is maintained.
The drainage block 3 is cut into 14 parts to make the drainage block 3 a simple flat shape,
It is possible to improve the adhesion with 11.

The drain block 3 is fixed to the prospective piece 12 or the finding piece 13 of the longitudinal member 1 constituting the swallowing groove 11 at a position where the filling groove 32 is removed by a screw 5 penetrating the screw hole 15.

After the drain block 3 is fixed to the vertical member 1, the filling groove 32 is filled with a wet sealing material 4. The sealing material 4 is supplied from the filling port 16 formed in the prospective piece 12 of the longitudinal member 1 as shown in FIG. 5, through the filling port 34 of the drain block 3 formed in a corresponding position, or as shown in FIG. The filling gun 6 injects the filling groove 32 whose material 2 side is open from one side in the expected direction. The filling state is confirmed by discharging the sealing material 4 from the surface on the side of the cross member 2 because the filling groove 32 is continuous.

The drain block 3 abuts on the end face of the cross member 2 with the sealer 7 interposed therebetween when the cross member 2 is joined to the vertical member 1, and the horizontal member 2 penetrates the vertical member 1 and screw holes 25, 25 of the cross member 2. Is joined to the longitudinal member 1 by the screw 5 screwed into the swage groove 11 of the longitudinal member 1.

The drain block 3 receives rainwater falling in the swallow groove 11 on the upper surface 31 and guides the rainwater to the swallow groove 21 of the cross member 2.
From the swallowing groove 21 of the cross member 2, a prospective piece 22 constituting it
The water is discharged from the drain hole 24 opened outside the room.

[0016]

According to the present invention, the drain block accommodated in the swallow groove of the vertical member is fixed to the swallow groove, and the filling groove formed continuously around the drain block is filled with a wet sealing material. Since the gap between the drain block and the swallow groove is completely closed, it is possible to prevent rainwater from flowing from the drain block to the indoor side, and to ensure watertightness between the vertical member and the horizontal member. In addition, since the filling groove is continuous in the circumferential direction except for the surface of the filling material, it is possible to fill the sealing material from one of the filling material grooves. Since the completion of the filling operation can be confirmed by discharging from the other cross member side, it is possible to reliably fill the filling groove with the sealing material.
