Abstract

<P>PROBLEM TO BE SOLVED: To provide a synthetic resin joint sealing material capable of obtaining a joint excellent in air-tightness and water-tightness resulting from the adherence of butt end faces by pushing the joint sealing material against a flexible part 6 of the synthetic resin joint sealing material 2, following dimension variations of the joint sealing material by the deformation of a flexible material, facilitating the construction work and imparting good appearance. <P>SOLUTION: The synthetic resin joint sealing material 2 having an approximately hat-shaped cross section inserted in the joint section is so constituted that two hard materials having an L-shaped cross section as collar sections 3 and 3' oppose both short side sections 5 and 5' of them by opening a space and that the flexible material having an approximately M-shaped cross section for a side wall to slightly open the above across the space is connected to the upper part. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a synthetic resin joint material used when applying a decorative material.

  Conventionally, when constructing a decorative material on a wall surface, the decorative material is stored with a watermark or connected and joined. In general, it is fixed by using nails, screws, adhesion, or by using various types of synthetic resin joint materials such as T-shaped, hat-shaped, and square-shaped to enhance the decorativeness. In the case of decorative materials that are difficult to nailed or screwed in, the E-shaped synthetic resin joint material with a base part at the bottom and an umbrella part at the top is provided for ease of construction and aesthetics. It is constructed using.

  However, the synthetic resin joint material is crushed only from the soft material, or the synthetic resin joint material from the hard material alone cannot follow the dimensional accuracy of the decorative material, and the change in the thickness, length, and width of the decorative material, Distortion may occur when used for a long time.

  The present invention has been studied to eliminate such conventional drawbacks, and aims to provide a synthetic resin joint material capable of covering the poor dimensional accuracy and dimensional changes of decorative materials. It is a characteristic synthetic resin joint material. That is, the invention described in claim 1 is a synthetic resin joint material having a substantially hat-shaped cross section that is inserted into the joint part, and the two hard materials having the L-shaped cross-section of the collar portion with the gap between the short sides. A synthetic resin joint material characterized in that it is opened and faced, and a soft material having a substantially M-order cross-section that is slightly opened upward across the short side is joined to the upper part. .

  According to the present invention, by pressing the decorative material against the soft portion of the synthetic resin joint material, the joint surface is closely adhered and a joint excellent in airtightness and watertightness is obtained. Follow.

Hereinafter, the present invention will be described in detail based on the drawings. FIG. 1 is a front view of the synthetic resin joint material of the present invention.
The base pieces are two hard materials having an L-shaped cross section. The short sides 5 and 5 'of the hard material face each other with a gap therebetween, and the soft material 6 is joined on the short sides 5 and 5' across the gap. By making a gap, when the decorative material is pressed, it repels due to its elasticity and adheres to the decorative material.
The soft material 6 has a substantially M-shaped cross section and is somewhat open upward, so that the decorative material is pressed against it. Thus, by making the head of the soft material 6 concave and making it M-shaped, the expansion and contraction of the decorative material is absorbed near the center, and the synthetic resin joint material 2 does not pop up.
By combining the soft material and the hard material in this way, the gap between the hard material and the soft material give elasticity, and the decorative material is horizontally fixed by the adhesive at the flange portions 3 and 3 'of the hard material.

  Production of the synthetic resin joint material 2 of the present invention may be carried out using an apparatus generally used for plastic extrusion, such as a ram type extruder, a single screw type extruder, a vent type extruder, etc. A soft resin and a hard resin are supplied to a screw type extruder, etc., melted, and extruded from a molding die. In particular, a screw extruder capable of continuous operation is more preferable.

  Examples of the thermoplastic resin used include soft polypropylene, soft polyethylene, soft vinyl chloride, and soft acrylonitrile-butadiene-styrene (ABS) as the soft resin, and hard acrylonitrile-butadiene-styrene (ABS) as the hard resin. ), Hard polypropylene, polystyrene, hard polyethylene, hard vinyl chloride and the like. In the present invention, soft ABS and hard ABS are used.

  There are no particular restrictions on the decorative material, a thermosetting resin decorative board, plywood, particle board made of a thermosetting resin such as a melamine resin, diallyl phthalate resin, unsaturated polyester resin, or a mixed resin using these resins in combination. Laminated plywood with resin-impregnated decorative paper laminated to a woody base material such as medium density fiberboard, PVC decorative plywood, veneered decorative plywood, gypsum board, laminated with vinyl chloride sheet, veneer, etc. Widely known materials such as composite decorative materials obtained by laminating and adhering decorative sheets such as resin-impregnated decorative paper, vinyl chloride sheet, and veneer to an inorganic base material such as a calcium-based board can be applied.

  In addition to the above, there is no particular limitation as long as it has design properties, water resistance, heat resistance, and rigidity. For example, a cast product obtained by casting a resin such as an acrylic resin or an unsaturated polyester resin, Polyester resin decorative panels obtained by film-forming with unsaturated polyester resin can be applied, but preferably cast products that have excellent resistance to contamination and abrasion and are resistant to scratches It is also preferable to use a melamine resin decorative board.
