  The louver is horizontally drawn. It is an object of the present invention to provide a louver core material, a louver with a core material, and a louver installation structure in which a louver can be easily and firmly installed vertically or vertically.

  The core material for a louver according to claim 1 is a core material that is inserted into and bonded to a hollow cylindrical ceramic louver that is installed vertically, and is attached to the side surface bonded to the inner surface of the louver in the longitudinal direction of the core material. An extending ridge is provided.

  The louver core material according to claim 2 is characterized in that, in claim 1, one ridge is provided on one side surface of the core material.

  The core material for louvers of claim 3 is characterized in that, in claim 1 or 2, a groove surface comprising a plurality of grooves extending in a direction parallel to the ridges is provided on the side surface. is there.

  A louver with a core material according to a fourth aspect is formed by inserting and bonding the louver core material according to any one of the first to third aspects through a ceramic louver.

  The louver with a core material according to claim 5 is characterized in that, in claim 4, the louver has a rectangular tube shape, and two adjacent surfaces of the inner surface of the louver are bonded to adjacent side surfaces of the core material. is there.

  The louver with a core material according to claim 6 is characterized in that, in claim 4 or 5, the ridges of the core material are in contact with the inner surface of the louver.

  The louver installation structure of claim 7 includes a plurality of upper louvers in which the core-equipped louvers according to any one of claims 4 to 6 are arranged in parallel in the vertical direction, and are disposed horizontally above the louvers. A core member is fixed to a lower frame disposed horizontally below the louver.

  In the core material for louvers, the louver with the core material, and the louver installation structure of the present invention, since the ridges are extended on the side surface of the core material in the longitudinal direction of the core material, the adhesive is applied to the side surface of the core material. When this is done, this ridge can be used for the boundary line of the adhesive application region, guidance for the adhesive application work, or the like. Thereby, the range which should apply an adhesive agent becomes easy to understand.

  Further, when the side surface of the core member is pressed against the inner surface of the louver, the protrusions abut against the inner surface of the louver as in claim 6 to prevent the adhesive from being excessively thinly spread. That is, when the core material and the louver inner surface are bonded, an adhesive layer having a thickness corresponding to the height of the ridge is formed between the core material and the louver inner surface. Thereby, for example, even if a rivet or screw head is present on the side surface of the core material, the head is prevented from directly hitting the inner surface of the louver.

  Further, since the adhesive layer has a predetermined thickness, even when a difference in thermal expansion occurs between the core material and the louver, the shear stress generated in the adhesive layer becomes small.

  As in claim 2, when one ridge is provided on one side surface of the core material, when rainwater or the like enters between the side surface of the core material and the inner surface of the louver, water may accumulate between the two. Is prevented. That is, when a plurality of ridges are provided on one side surface, when water enters between the side surface of the core and the inner surface of the louver, the water is on the upper side of the adhesive layer in the portion between the ridges. Water may accumulate in the area. On the other hand, when only one ridge is provided on one side as in claim 3, water flows down to the opposite side of the ridge, and adhesion between the core side surface and the louver inner surface is performed. Water does not collect in the upper area of the agent.

  When the groove surface is provided as in the third aspect, the application area of the adhesive becomes easy to understand. Further, when the groove is provided, the specific surface area of the core material surface is increased, so that the adhesion area between the adhesive and the core material is increased, and the adhesive strength between the core material and the louver is increased. When the core material is made of an aluminum extruded material or the like, the effect of increasing the adhesive force of the adhesive by providing the groove surface becomes remarkable because the side surface becomes smooth.

  When the two adjacent surfaces of the inner surface of the louver are bonded to the two side surfaces of the core material as in claim 5, the bonding between the core material and the louver becomes firm in the two orthogonal directions in the horizontal plane. Further, even when the internal dimensions of the louver vary, the two side surfaces of the core material and the two side surfaces of the louver can be faced to overlap each other, and the core material and the louver can be firmly bonded.

  Hereinafter, embodiments will be described with reference to the drawings.
