Abstract: A projected corner structure in which two upright columns 3 and 4 substantially rectangular in cross section are disposed on a diagonal line in a pair of bracket-shaped runners (1, 2) arranged at an angle of about 90° on a floor surface. A corner upright column 5 of a synthetic resin including an outer end portion 5b having an outer surface formed in the form of a circular arc stands upright fitted into a substantially angular clearance C formed on an exterior side between the upright columns. Projecting portions 9 and 10 are formed integrally on lateral portions on both sides of the corner upright column, and are arranged to fit over interior side surfaces of the respective upright columns, and are fastened to the upright columns by countersunk screws 11 and 12. The resulting structure combines simplified construction with increased strength, improved appearance, and decreased cost.

Abstract: A central support section 1 having a rectangular cross-section was arranged at a central position, and a plurality of winding support sections 2-5, 6-9 . . . of a substantially elongate platelike shape were combined and arranged around the central support section, while being sequentially swirlingly and spirally wound, and each support section was fixed in a laminated condition between inside and outside. Furthermore, the support unit bodies 15 were engaged into a fitted condition from vertical directions and connected together by adhesive, thereby forming a square pillar 16. With this, there is provided a support structure that is capable of freely setting the size of the outer diameter while securing axis of the support and obtaining a sufficient strength.

Abstract: Two upright columns 3 and 4 substantially rectangular in cross section are placed closely substantially on a diagonal line in a pair of substantially bracket-shaped runners(1, 2) arranged at an angle of about 90° on a floor surface. Moreover, a corner upright column 5 of a synthetic resin including an outer end portion 5b whose outer surface is formed in the form of a circular arc stands upright in a fitting state in a substantially angular clearance C formed on an outer side between the upright columns. Furthermore, projecting portions 9 and 10 are formed integrally in side portions on both sides of the corner upright column, arranged to fit over interior side surfaces of the upright columns, respectively, and fastened to the upright columns by a plurality of countersunk screws 11 and 12. Therefore, it becomes possible to increase the strength of the projected corner, improve the quality of appearance, simplify the construction, and decrease the cost.

Abstract: The invention relates to an interior panel structure including first and second panels formed into an L-shaped panel structure and an L-shaped reinforcing member fixed to an outer corner portion of the L-shaped panel structure. The reinforcing member has a plurality of first through holes that are opposed to a minor face of the first panel. With this, it is possible to observe condition of the minor face of the first panel and remove major projections of the minor face. Thus, the interior panel structure is improved in external appearance.

Abstract: The invention relates to a first gypsum-based composite article reinforced with glass fibers. This first article has a first member made of a hard gypsum, a second member made of a soft gypsum, and a mat made of the glass fibers. The mat is embedded in the article in a manner that the first and second members are bonded together by means of the mat. This first article is superior in resistance to external force acting thereon and to severe environmental conditions, even if the gypsumbased article is light in weight and thin in thickness. The invention further relates to a second gypsum-based composite article having a base plate, a glass fiber mat bonded to the base plate, and a gypsum layer formed on the glass fiber mat such that glass fibers of the glass fiber mat are embedded in the gypsum layer. This second article also has superior characteristics as those of the first article.
