What has improved sealing performance is used widely conventionally. However, the conventional means for sealing a joint groove using the sealing material 105 is, for example, when the sealing material 105 is filled in a joint groove between adjacent floor materials, a person walks on the joint groove. Since an external force acts directly on the sealing material 105 itself due to vibration, earthquake, or the like, there is a problem that the sealing material 105 is partially separated from the joint groove and comes off from the joint groove. .

[0003]

The technical problem of the present invention is that the joint material constituting the joint material is partially sandwiched between adjacent panels inside and outside the building, so that the joint material is formed by the joint groove. It is an object of the present invention to provide a joint material that can prevent inward immersion or withdrawal from the joint groove, and can further ensure good sealing performance in the joint groove.

[0004]

In order to solve the above-mentioned problems, a first joint material of the present invention is a joint material provided in a joint groove between panels inside and outside a building. The joint base material, which includes a sealing material and a core material and is made of a synthetic resin, is formed in a substantially U-shaped cross section by connecting left and right flexible side plates with a bottom plate. On the side,
A soft sealing piece is provided, the tip of which is pressed against the end face of the panel to seal the part, and a number of holes are drilled below the sealing pieces on the both side plates, so that a gap between both side plates of the joint base material is provided.

A core portion that is pressed out from the hole of the side plate, and a flange plate of a soft head that abuts on the joint groove mouth portion and seals the gap between the core portion and the joint portion are formed in a substantially T-shaped cross-section, The joint base is provided with a sandwiching piece extending from a bottom plate of the joint base, formed in a shape along an end face of the panel, and sandwiched between adjacent panels.

[0005] The second joint material of the present invention comprises the first joint material.
The joint material is provided in the same joint groove as the joint material, and includes a joint base material and a core material, and the synthetic resin joint material connects the left and right side plates having flexibility with a bottom plate. In this manner, a soft sealing piece is provided on the outer surface of the side plate, the tip of which is pressed against the end surface of the panel to seal the portion. The core material to be pushed into the joint base material is to expand the side plates of the joint base material and press the seal pieces on the outer surfaces of the side plates against the inner side wall of the joint groove, and to contact the joint groove opening portion with the core portion. And a flange plate having a soft head for sealing the gap between the joint base material and the bottom plate in the joint base material. Characterized in that a holding piece is formed along the shape and held between adjacent panels. It is intended.

[0006] In the first and second joint materials, at least one or more soft seal pieces can be provided on the surface of the sandwiching piece in the joint base material.

[0007] When the first and second joint materials are applied, the joint base material of the joint base material is previously sandwiched between adjacent panels at the time of panel installation.

On the other hand, the second joint material pushes the core of the core material between the side plates of the joint base material to expand the both side plates, and the sealing portion piece on the outer surface of the side plate is joined to the joint groove. At the same time as being pressed against the inner side wall, the joint groove opening is covered with the flange plate of the core material head. At this time, in the second joint material, the tongue-shaped wing portion of the core material head is pressed against the joint groove opening portion to perform primary sealing therebetween. Then, since both side plates of the joint base material are expanded and the seal pieces on the outer surface of the side plate are pressed against the inner wall of the joint groove to perform a secondary seal, the joint groove is reliably maintained while maintaining watertightness. Sealing can be performed, and at the same time, variations in the width of joint grooves can be sufficiently coped with.

As described above, according to the joint material of the present invention, the sandwiching piece extending from the bottom plate of the joint base material and formed along the end face of the panel is sandwiched between adjacent panels. The joint base can be positioned only by installing the joint base in the joint groove, and the installation work of the joint base can be simplified, and even when external force acts on the joint base itself,
Since the joint material can be prevented from immersing into the joint groove or coming out of the joint groove, good sealing performance in the joint groove can be ensured.
