  In addition, since the fixing member is slidably mounted on the cross rail, an excellent effect is obtained that the face material is not damaged due to the interlayer displacement.

  Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.

  An inner wall structure 10 according to an embodiment of the present invention is shown in a horizontal sectional view in FIG.

  As shown in FIG. 1, the inner wall structure 10 includes a horizontal rail 11 disposed between columns 1 and 2, an inner wall base material (face material) 12 disposed on the surface of the horizontal rail 11, and an inner wall base material. The surface finishing material 13 affixed to the surface of 12 is provided as a main component.

  The crosspiece 11 is, for example, a thin-walled square steel pipe, and is disposed between the columns 1 and 2 by a fixing member 20 having base end portions 22 slidably mounted at both ends thereof. A buffer material 14 is interposed at a location where the outer wall 3 of the horizontal rail 11 intersects the vertical trunk edge 4. As the buffer material 14, for example, a foamed synthetic resin is used.

  FIG. 2 shows the fixing member 20.

  As shown in FIG. 2, the fixing member 20 includes a flat mounting portion 21 and a base end portion 22 formed by bending a flat plate into a U-shape.

  The mounting portion 21 is formed with a required number of through holes 23 (1 in the illustrated example) for screwing the fixing member 20 to the indoor side surfaces of the columns 1 and 2. Further, the size of the base end portion 22 is adjusted so that it can be slidably mounted (internally fitted) on the end portion of the horizontal rail 11.

  In addition, since the inner wall base material 12 and the surface finishing material 13 are the same as those in the conventional art, detailed description of their configurations is omitted.

  Next, the construction of the inner wall structure 10 having such a configuration will be described.

  Procedure 1: The fixing members 20 are attached to both ends of the horizontal rail 11 (see FIG. 3). This procedure may be performed at the factory.

  Procedure 2: The crosspieces 11 are arranged at predetermined intervals between the pillars 1 and 2 (see FIG. 4). That is, the mounting portion 21 of the fixing member 20 is screwed to the indoor side surfaces of the columns 1 and 2. This procedure may be performed at the factory. FIG. 4 shows a state in which the cross rail 11 is attached to the columns 1 and 2 in the factory.

  Procedure 3: A cushioning material 14 is disposed at a location where the crosspiece 11 intersects the vertical trunk edge 4 of the outer wall 3.

  Procedure 4: Arrange the inner wall base material 12 so as to pass between the columns 1 and 2. That is, the inner wall base material 12 is screwed and fixed to the indoor side surface of the horizontal rail 11.

  Procedure 5: A surface finishing material 13 is disposed on the surface of the inner wall base material 12. This arrangement is made using a detachable tape such as Velcro (registered trademark).

  The construction of the inner wall structure 10 is completed by the above procedure.

  In addition, when the crosspiece 11 is arrange | positioned between the pillars 1 and 2 in a factory, after the pillars 1 and 2 are stood on the foundation, the procedure 3 and subsequent are performed.

  As described above, in the inner wall structure 10 of the present embodiment, since the cross rail 11 is disposed between the columns 1 and 2, the amount of protrusion of the inner wall base material 12 from the steel surface is minimized. And the inner wall thickness can be reduced. Therefore, the effective indoor volume can be increased.

  Further, since the fixing member 20 is slidably attached to the end portion of the horizontal rail 11, transmission of the displacement to the inner wall base material 12 is blocked even if an interlayer displacement occurs. This prevents damage such as damage to the inner wall base material 12 and cracks in the surface finish 13 due to interlayer displacement.

  Further, by appropriately adjusting the length of the base end portion 22 of the fixing member 20, even if the length of the horizontal beam 11 is made constant, that is, even when the horizontal beam 11 is standardized, the distance between the columns is different. Applicable to buildings.

  In addition, since the cushioning material 14 is disposed at the intersection between the horizontal rail 11 and the vertical trunk edge 4 of the outer wall 3, the deflection of the horizontal rail 11 can be reduced. Therefore, the bending of the inner wall base material 12 can be within an allowable range with a small number of horizontal bars 11.

  In addition, since the number of the horizontal rails 11 may be small, the manufacturing period and the construction period can be shortened, and the manufacturing cost and the construction cost can be reduced.

  As mentioned above, although this invention has been demonstrated based on embodiment, this invention is not limited only to this embodiment, A various change is possible.

  For example, in the embodiment, the fixing member 20 is slidably attached to both ends of the horizontal rail 11, but the fixing member 20 at one end may be slidable. In that case, instead of the fixing member 20, a fixing portion may be formed on the horizontal rail 11. Thus, by making one end slidable and fixing the other end as a fixed or fixed portion, the strength of the steel structure including the cross rail 11 at the construction stage is ensured, and the effect of improving the construction efficiency is expected. The

  Further, in the backyard or the like, the surface finishing material 13 can be omitted. Moreover, the surface finishing material 13 can also be abbreviate | omitted by making the inner wall base material 12 into a decorative member.

  Further, the construction method is not limited to the above, and the fixing member 20 is slidably attached to one end of the horizontal beam 11 and then the attaching portion 21 of the fixing member 20 is screwed to the column 1 (or 2). After fixing, the other fixing member 20 may be attached to the cross rail 11.

  The present invention can be applied to an inner wall structure.
