It is installed between the members 103. Here, the louver 100 is installed at an angle parallel or intersecting with the outer surface of the building. The upper end member 102 and the lower end member 103 are concrete plates or the like.

  In the louver 100, the lower surface of the second spacer 31 contacts the support portion 104 provided on the upper surface of the lower end member 103 and the pair of rotation restricting portions 105, and the pair of rotation restricting portions 106 provided on the lower surface of the upper end member 102 It installs in the state which the upper surface of one spacer 30 contacts. The rotation of the louver 100 is restricted by the second spacer 31 supported by the support part 104 and the spacers 30 and 31 touching the rotation restricting parts 105 and 106. A clearance between the louver 100 and the upper end member 102 and a clearance between the louver 100 and the lower end member 103 are filled with a sealing material 107, respectively. The gap may not be filled with the sealing material 107.

  Then, an example of a manufacturing method of louver 100 of this embodiment is explained. The following description will be made on the basis of the orientation in the fallen posture. The upper end of the louver 100 in the standing posture corresponds to the front end of the louver 100 in the lying posture, and the front surface of the louver 100 in the standing posture corresponds to the top surface of the louver 100 in the lying posture.

  First, the second plate member 2 is placed flat, and the first spacer 30, the second spacer 31, the third spacer 32, and the fourth spacer 33 are formed in a rectangular frame shape in plan view on the upper surface of the rear surface portion 20 of the second plate member 2. Place on Then, the reinforcing member 7 is placed on the upper surface of the rear surface portion 20 of the second plate member 2.

The rotation of the louver 100 is restricted by the upper pair of rotation restricting parts 106 and the lower pair of rotation restricting parts 105.

  Next, a caulking agent is filled in the gap between the louver 100 and the upper end member 102 and the gap between the louver 100 and the lower end member 103 to fill the two gaps with the sealing material 107.

  As described above, the louver 100 is fixed between the upper end member 102 and the lower end member 103. Here, the louver 100 is installed, for example, at an angle intersecting with the outer surface of the window of the building 101 to block the window.

  Then, the modification of embodiment mentioned above is demonstrated.

  In the embodiment described above, the louver 100 is provided with the fasteners 5 and 6 for fastening the plate members 1 and 2 to the spacer unit 3, but the fasteners 5 and 6 may be omitted.

  Moreover, in the embodiment mentioned above, although the louver 100 provided the reinforcement member 7 inside the spacer unit 3, the reinforcement member 7 may be abbreviate | omitted.

  Moreover, in embodiment mentioned above, although the louver 100 provided the makeup cover 8 in the edge part on either side, the makeup cover 8 may be abbreviate | omitted.

  Moreover, in the embodiment described above, the louver 100 is installed on the building-side support member (upper end member 102, lower end member 103) in a vertical orientation in which the longitudinal direction is parallel to the vertical direction. You may install in the supporting member by the side of a building by the sideways attitude | position which becomes the left-right direction. At this time, the louver 100 may be installed in a posture that is parallel to the upper end member 102 or may be installed in an inclined posture with respect to the upper end member 102.

  In the embodiment described above, the louver 100 is vertically supported by the support member on the building side in the vertical orientation, but one or both of the left and right ends are supported by the support member on the building side May be installed.

  Moreover, in the embodiment described above, the louver 100 is arranged in a rectangular frame so that the plurality of spacers are positioned so that the longitudinal end portions abut each other, but between the adjacent two spacers There may be some gaps. Also, the gap may be formed by sandwiching another member between two adjacent spacers.

  Moreover, in embodiment mentioned above, although the louver 100 had four linear square-shaped spacers of the spacer unit 3, it is not limited to this. That is, the spacer unit 3 should just be comprised by the several spacer arrangeable to frame shape.

  That is, in the louver 100 according to the embodiment of the present invention, the first plate 1 and the second plate 2 are fixed to the spacer unit 3 via the bonding portion 4 and the fixing tools 5 and 6, respectively.

  By providing the above-described additional configuration, in the louver 100 according to the embodiment of the present invention, the plate members 1 and 2 can be fixed by the fixing tools 5 and 6 even when the adhesive force by the bonding portion 4 is weakened due to aging or fire. It is possible to suppress detachment from the spacer unit 3.

  Further, in the louver 100 according to the embodiment of the present invention, since the plate members 1 and 2, the spacer unit 3 and the fixtures 5 and 6 are all made of metal, the plate members 1 and 2 are further prevented from coming off the spacer unit 3. be able to.

  Further, in the louver 100 according to the embodiment of the present invention, by using adhesion by the bonding portion 4 as one of fixing means for the plate members 1 and 2 and the spacer unit 3, the plate members 1 and 2 can be used as the front surface of the spacer unit 3. It is possible to stick to the whole and the entire rear surface, and it is possible to suppress the bending of the plates 1 and 2 even when the plates 1 and 2 are thin.

  Further, in the louver 100 according to the embodiment of the present invention, the fixing tools 5 and 6 for fixing the plates 1 and 2 to the spacer unit 3 are covered with the cosmetic cover 8 to improve the appearance and aerodynamic characteristics and to fix them. The tools 5 and 6 can be prevented from falling off.

  As mentioned above, although this invention was demonstrated based on embodiment shown to an attached drawing, this invention is not limited to said embodiment, As long as it is in the range which this invention intends, a design change is possible suitably. It is.
