  However, when the face material is made of structural plywood or inorganic material, it lacks the strength of the face material, but lacks the stickiness that affects the deformability of the building, causing brittle fracture in the event of an earthquake, etc. There is a fear. In addition, when the face material is made of structural plywood or inorganic material, the strength is adjusted according to the number of nails that secure the face material to the structural frame of the building. There is a risk that the number of nails will be missed and appropriate strength will not be achieved. On the other hand, when the face material is formed from punched metal, further improvement in the strength of the face material is desired.

  As a result of diligent research on a surface material having better strength, the present applicant has found that a surface material obtained by superimposing a steel plate on one surface of a plywood is effective. However, if a steel plate is provided only on one plate surface of the plywood, local out-of-plane buckling of the steel plate occurs during an earthquake or the like, and there is a possibility that improvement in yield strength cannot be expected.

  The present invention has been made in view of such problems, and its main purpose is to prevent brittle fracture and out-of-plane buckling that occur in the event of an earthquake, etc., and to easily adjust the yield strength. It is in providing the face material which can be performed reliably.

  The face material according to the present invention for achieving the above object is a plate-like steel porous material having a large number of through-holes, and is laminated so as to sandwich the porous material from both sides in the thickness direction, A pair of plate-like coating materials provided on the porous material, and the porous material is provided with the pair of coating materials, whereby the openings at both axial ends of the through-holes are closed to form hollow portions. It is characterized by that.

  In the face material according to the present invention, the porous material is a punching metal.

  Furthermore, the face material according to the present invention is characterized in that each of the pair of covering materials is a plywood.

  According to the face material according to the present invention, since it has a steel porous material, it is possible to obtain a large yield strength and a firm deformation performance compared to a face material made of structural plywood or an inorganic material. . Further, since the porous material is sandwiched between the pair of covering materials, the out-of-plane buckling of the porous material can be prevented. Furthermore, the strength and rigidity of the face material itself can be adjusted by adjusting the size of the through hole of the porous material and / or the number of through holes to be formed. And it can be done reliably.

  Moreover, according to the face material which concerns on this invention, a porous material can be manufactured easily and, thereby, the manufacturing cost of a face material can be reduced.

  Furthermore, according to the face material according to the present invention, the cost of the covering material can be reduced, and the strength of the face material can be improved.

  The structural frame 5 of the building is constituted by a beam 6, a base 7, and a plurality of pillars 8, 8,. The beam 6 and the base 7 are spaced apart from each other in parallel and are formed of square bars. Each column 8 is arranged vertically and is formed from square bars. The plurality of pillars 8 are fixed to the upper surface of the base 7 so as to be spaced apart from each other on the left and right. The beam 6 is fixed to each column 8 in a state where the beam 6 is placed on the upper surface of each fixed column 8. In this way, the structural frame 5 is configured in a substantially rectangular frame shape by the beam 6 and the base 7 that are spaced apart from each other in the vertical direction and the two columns 8 and 8 that are spaced apart from each other on the left and right. As a result, a rectangular opening 9 surrounded by the beam 6, the base 7, and the two pillars 8 and 8 is formed in the structural housing 5.

  The face material 1 is fixed to the structural housing 5. The face material 1 has a rectangular plate shape and is formed larger than the opening 9 of the structural housing 5. Specifically, the face material 1 is formed so that the vertical length is longer than the vertical length of the opening 9 and the horizontal length is longer than the horizontal length of the opening 9.

Specifically, one covering material 4 is provided so as to be superimposed on the front surface of the porous material 3, and the other covering material 4 is provided so as to be superimposed on the rear surface of the porous material 3. In this embodiment, the porous material 3 and each coating material 4 are bonded by an adhesive. In this way, the face material 1 having the porous material 3 and the pair of coating materials 4 and 4 is formed.

Therefore, brittle fracture of the face material 1 can be prevented. Further, in the case of the face material 1 of the present embodiment, since the porous material 3 is sandwiched between the pair of covering materials 4 and 4, out-of-plane buckling of the porous material 3 during an earthquake or the like can be prevented.
