DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure provided at a joint portion of a building wall plate.

[0002]

2. Description of the Related Art Conventionally, a joint structure at a joint portion of a wall plate of a building is provided with a joint structure for the purpose of waterproofing and fire prevention. As the joint structure, a fixed joint structure and an irregular joint structure are known. The former fixed joint structure is formed by extruding a synthetic resin, rubber, or the like into a predetermined shape, and is used by being fitted to the joint. Further, the latter irregular-shaped joint structure is made of a paste-like rubber or resin, and is used by filling the joint.

[0003] However, in the former fixed joint structure, since it is a molded product, it is difficult to completely cope with the unevenness of the inner wall surface of the joint, and a gap may be formed in the joint. On the other hand, since the latter irregular-shaped joint structure has fluidity, it can be filled without gaps regardless of the irregular surface state of the joint inner wall, but it is necessary to provide a so-called backup material to regulate the joint depth. is there. Further, in order to prevent the irregular-shaped joint structure from adhering to the surface of the wall plate and becoming dirty, a masking process must be applied to the wall surface in advance. Furthermore, the joint surface provided with the irregular-shaped joint structure has a problem in that not only the surface must be flattened with a trowel or the like to improve the appearance, and there is a problem in workability, but it is difficult to achieve a uniform finished state. is there.

In order to solve such a problem, Japanese Utility Model Publication No. 5-14962 discloses a fixed joint material having a substantially U-shaped cross section having a sealing ridge on a side surface and an open back surface. A joint material is disclosed in which an irregular-shaped sealing material is filled in the opening on the back surface side and the back surface of the opening is covered with a film.

[0005] This joint material is pressed into the joint with the flexible fixed joint material on the wall side of the building, and at this time, the film covering the opening is broken by the pressing deformation of the fixed joint material and the inside of the joint is broken. The irregular-shaped joint material is discharged and filled into the joint. According to the joint material, the surface side of the joint is formed of the fixed joint material, and the inside of the joint is filled with the irregular joint material.

However, in this structure, since the outflow direction of the irregular-shaped joint material is the depth direction of the joint, the irregular-shaped joint material may not sufficiently spread in the side direction. In that case, there is a possibility that the irregular-shaped joint material does not reliably contact the side wall of the joint and a gap is generated.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the joint structure of the present invention, FIG. 2 is a cross-sectional view showing a state where the joint structure is attached to a wall on one side of the joint, and FIG. FIG. 4 is a cross-sectional view of the joint structure showing a state where the width of the joint is wide, and FIG. 5 is a cross-sectional view of the joint structure showing a state where the width of the joint is narrow.

As shown in FIGS. 1 to 3, the joint structure 10 of the present invention comprises a fixed joint material 11 and a soft joint material 20.
And attached to the joint 50 of the wall W1 and the wall W2. The walls W1 and W2 on which the joint structure 10 of the present invention is provided are made of a panel-like wall material that is manufactured in advance in a factory and assembled on site.

The standard joint material 11 is made of a flexible synthetic resin or rubber and is continuous in the cross-sectional direction. The surface fins 12, the leg fins 13, the first intermediate fins 14, and the first terminal fins are provided. And a second end fin 16 and a second end fin 17.

The surface fins 12 are provided on the surface side of the joint 50 to improve the appearance, and are formed in the longitudinal direction of the fixed joint material 11. The width of this surface fin 12 is
It is preferable to form the joint width slightly larger than the standard size for setting the joint width to be attached.

The leg fins 13 are fixed from the back side of the surface fins 12 in the same manner as the surface fins 12.
Are vertically provided integrally in the longitudinal direction. This leg fin 13
On one side, a first intermediate fin 14 and a first terminal fin 15 are integrally provided in the longitudinal direction thereof, and on the other side, a second intermediate fin 16 and a second terminal fin 16 are similarly provided in the longitudinal direction. 17 are provided integrally.

The first intermediate fin 14 is provided with the leg fin 13.
Are protruded integrally from approximately the middle of the. A first terminal fin 15 is formed from the rear end of the leg fin 13 in the direction in which the first intermediate fin 14 projects. The first terminal fin 15 defines the rear end of the joint structure 10, holds a soft joint material 20 described later, controls the flow direction thereof, and efficiently extrudes it toward the joint inner wall surface.

The second intermediate fin 16 is formed integrally with the leg fin 13 in a direction opposite to the first intermediate fin 14. The second terminal fin 17 protrudes from the rear end of the leg fin 13, similarly to the first terminal fin 15. The second terminal fins 17 also define the rear end of the joint structure 10 to provide a soft joint material 2 described later.
By keeping the flow rate at 0, the flow is controlled so as to be efficiently extruded toward the joint inner wall surface.

As can be understood from the drawing, a space is formed between the first intermediate fin 14 and the first terminal fin 15. This space has an opening 23 on the inner wall surface side of the joint of the wall W1.
And the inside thereof is filled with the soft joint material 20 to form the first seal portion 21. On the other hand, the space formed between the second intermediate fin 16 and the second terminal fin 17 is filled with a soft joint material 20 to form a second seal portion 22. Reference numeral 24 denotes an opening of the second seal portion 22 formed on the joint wall surface side of the wall W2.

Here, the soft joint base material 20 will be described. The soft joint material 20 used in the present invention is also referred to as an amorphous joint material, and is preferably a known paste sealant such as an acrylic, butyl, or silicon material.
It is appropriately selected and used according to the type and use of the building material to be used.

The first seal portion 21 and the second seal portion 22 which are defined by the fins 14, 15, 16, 17 and are filled with a soft joint material 20 are formed by the joint structure 10 as a joint. The soft joint base material 20 is extruded from the openings 23 and 24 by pressing deformation when the soft joint base material 20 is fitted in the inside 50. Then, the soft joint material 20 is brought into close contact with the inner wall surface of each joint without any gap.

The filling of the soft joint material 20 into the first seal portion 21 and the second seal portion 22 can be performed each time at a construction site, but is performed in advance at the time of manufacturing the fixed shape joint material 11 or the like. You can keep it. At this time, in order to prevent the soft joint material 20 in the first seal portion 21 and the second seal portion 22 from drying and flowing out, it is preferable to cover each of the openings 23 and 24 with an appropriate resin film or the like.

As shown in FIG. 2, the joint structure 10 has the surface fins 12 on the surface side of the joints, and the first intermediate fins 14 and the first intermediate fins 14 and The terminal fin 15 is fixed by attaching the distal end to the joint 50 side wall surface of the wall W1.

In this example, the first intermediate fin 14
At the tip of the first terminal fin 15, flat portions 18, 18 formed substantially parallel to the leg fin 13 are provided. The flat portion 18 is formed by the joint 50 of the joint structure 10.
It is used to secure the pressure contact with the inner wall surface and to attach it in advance to the inner wall surface of the joint 50 of the one wall W1 via the double-sided tape 25 or the adhesive described above. Thus, the efficiency of construction work on site becomes extremely good.

Also, the tip of the first terminal fin 15 is flat.
The part 18 is a joint structure 10 opposite to the surface fin 12.
The joint structure 1 is formed so as to extend outward.
In order to secure the joint structure 10 to the wall and to prevent the joint structure 10 from dropping off during transportation or the like, the holding nail 2
6, the flat portion 1 at the tip of the first terminal fin 15
8 may be fixed to the wall W1. The flat portions 18 may be provided at both ends of the surface fin 12.
This ensures that the surface fin 12 is pressed against the inner wall surface of the joint 50 between the walls W1 and W2, thereby closing the gap.

Then, as shown in FIG. 3, at the construction site, first, a wall W1 to which the joint structure 10 is fixed is disposed, and then the wall W2 is connected to the tip of the second intermediate fin 16 and the second terminal. It is arranged so that the joint inner wall surface of the wall W2 is pressed against the tip of the fin 17. Thereby, the joint structure 10 is mounted in the joint 50. The joint structure 10 attached to the joint in this manner is a surface fin 1
2. The tips of the first intermediate fin 14 and the first terminal fin 15 are pressed against the joint inner wall surface of the wall W1, and the surface fin 12, the second intermediate fin 16 and the second terminal fin 17 are formed on the wall W2. It is in a state of being pressed against the inner wall surface of the joint. Due to the compressive deformation of the joint structure 10 at the time of the attachment, the soft joint material 20 inside is pushed out from the openings 23 and 24 of the first seal portion 21 and the second seal portion 22 into the joint 50 and filled therein. The extruded soft joint material 20 flows toward the joint inner wall surface by the first terminal fin pieces 15 and the second terminal fin pieces 17, so that the soft joint material 20 reliably adheres to the joint inner wall surface, and the leg fin pieces 13 and the joint 50. Filled between the inner walls.

In the leg fin 13, a thick portion 19 is provided near the base of the second intermediate fin 16. When the joint structure 10 is compressed by the wall W <b> 1 and the wall W <b> 2, the thick portion 19 is provided with the first seal portion 2.
The soft joint material 20 in the first and second seal portions 22 is extruded toward the joint wall surface so as to easily adhere to the joint inner wall surface. Further, the presence of the thick portion 19 imparts shape retention and rigidity to the leg fins 13, so that the fixed-shaped joint material 11 can be securely mounted in the joint regardless of the joint width. .

FIG. 4 shows a joint structure 10 of the present invention,
1 shows a state where the joint width between the wall 1 and the wall W2 is provided at a wide portion. As shown, in this joint 51, each fin piece 12, 14, 15, 16, 17 of the joint structure 10 is a wall W
Absorbing the dimensional change of the joint width between the first joint 1 and the wall W2, and reliably pressing against the joint inner wall surface, the soft joint material 20 is effectively filled in the seal portion.

FIG. 5 shows a joint structure 10 according to the present invention.
Is attached to a part where the walls W1 and W2 are close to each other and the joint width is narrow. As shown, this joint structure 10
Can be reliably attached to the joint 52 by the deformation of the fins. Also, at this time, the soft joint material 20 in the first seal portion 21 and the second seal portion 22 is strongly pushed out to the inner wall surface side of the joint 52 by the thick portion 19, so that the joint 52 is filled without gaps. can do. The joint structure may be fixed in advance to a wall panel on one side in a factory or the like, or may be attached to a wall at each site.
