Description

  The present invention relates to a synthetic resin wall plate material, and more particularly to a wall plate material arranged at a corner (corner portion), which can be applied to both an outgoing corner and an incoming corner. It relates to plate materials.

  When constructing a wall surface of a building, various types of wall plate materials (decorative plates) attached to the lower ground of the wall have been manufactured and supplied to the market. Such wall plate material is often configured so that end portions are provided on both left and right side edges, and the protrusions and grooves on the side edges of adjacent wall plate materials can be fitted and connected. In this case, only one side edge portion (the side edge portion of the wall plate material arranged first) needs to be fixed to the lower ground of the wall (such as screwing) (that is, the side edge portion of the next wall plate material arranged adjacently) Since it is only necessary to connect to the fixed side edge portion of the wall plate material arranged in advance, it is not necessary to fix the screw to the base surface again, so that the work can be performed efficiently.

  By the way, when a corner or a corner is formed on the wall surface to be constructed, it is not possible to work efficiently only with a normal (planar) wall plate material, and a beautiful wall surface. In addition to the flat wall plate material, the wall plate material exclusively for the projecting corner and the wall plate material exclusively for the entry corner are prepared in the product lineup as so-called “actors”. In many cases, such a material dedicated to corners is in a state where the plate material is bent at a right angle, so that it is bulky and complicated in packaging and inventory management compared to a flat plate material.

  The present invention is intended to solve the above-described problems in the prior art, and can be applied to both of the corners and the corners of entry, and before assembly (before separation), the packaging and An object of the present invention is to provide a corner wall plate material that can be handled as a flat product that can be easily managed.

  The corner wall plate material according to the present invention is a synthetic resin wall plate material in which a cross section perpendicular to the longitudinal direction is constant in the longitudinal direction, and a thin wall portion is formed. By being folded, it is configured so that it can be separated into the first member and the second member on both the left and right sides of the thin part, and the first part is opposite to the thin part among the two end parts of the first member. The connecting portion is formed, and the second connecting portion is formed at the end opposite to the thin portion of the both ends of the second member, and by fitting the first connecting portion and the second connecting portion, The separated first member and second member are configured to be connected at an angle of 90 °.

  In addition, when the first member and the second member are arranged and fixed on the lower ground of the wall of the structure, the front side portion that is exposed to the space side to form the wall surface, the back side portion that contacts the ground surface, and the ground surface And a back side fixing portion for fixing the corner wall plate material to the base surface, and the first connecting portion of the first member extends from the outer corner portion of the front side portion toward the inner side 45 °. Consists of a front-side inclined protruding portion that protrudes in a direction opposite to the front-side inclined protruding portion from the back-side portion at a position spaced apart from the front-side inclined protruding portion. And the second connecting portion of the second member is an inclined protruding portion that protrudes in the direction of 45 ° inside from the outer corner portion of the front side portion, and the folded portion formed so as to be folded back outwardly from the tip thereof in a U-shape. It is preferable that it is comprised by these.

  Further, the distance dimension between the front inclined ridge portion and the back inclined ridge portion in the first connecting portion corresponds to the thickness dimension of the inclined protruding portion in the second connecting portion, and the inclined protruding portion and the folded portion in the second connecting portion. It is preferable that the space | interval dimension with a part respond | corresponds to the thickness dimension of the front side inclined protrusion part in a 1st connection part.

  Furthermore, when the 1st member and the 2nd member are faced | matched so that the front side part of a 1st member and the front side part of a 2nd member may become a corner shape, the front side inclined protrusion part and 2nd of a 1st member The inclined protrusions of the members are arranged in a straight line in the direction of 45 ° obliquely, and a linear space is formed between these, the back-side inclined protrusions, and the folded part. It is preferable.

  The corner wall plate material according to the present invention can be applied to both the exit corner and the entrance corner, and is very versatile. The product is a wall plate material dedicated to the exit corner and the wall plate material dedicated to the entrance corner. Compared to the case of aligning with the lineup, only one type of mold material is required, and manufacturing costs can be greatly reduced, and inventory management becomes easy. Moreover, since it is flat before separating the first member and the second member at the position of the thin portion, packaging and inventory management are easy, and the number of the first member and the second member is not uniform. There is no inconvenience.
