Description

  The present invention relates to a wall support structure in a building, and more particularly to a wall support structure having high rigidity without using a frame.

  Conventionally, as a structure that supports a plurality of walls constituting the wall surface of a building, a horizontally long frame that supports a bracket so as to be immovable in a direction perpendicular to the wall surface with respect to the building frame and holds the upper and lower edges of the wall body. There is a structure in which the bracket is lifted and supported by connection support means that is provided on the bracket and connects between the bracket and the building frame. In this structure, the vertical frame which hold | maintains the both right-and-left edge of a wall body between the brackets arrange | positioned up and down is further provided (for example, refer patent document 1).

JP 2000-17762 A

  However, in the conventional structure, each frame that supports the wall body is provided via a bracket, and the bracket is provided via a building frame. That is, there is a problem that the structure becomes complicated because the double support structure is provided to support the wall body. In addition, particularly when the wall is made of glass, there is a problem that the scenery from inside and outside the building is damaged.

  A glass facade support structure using cable materials such as cable trusses and cable nets is also known as an improvement of the above problem, but when a large wall surface is constructed, the deformation of the wall surface against the wind increases, and the cable There is a problem that the cross section of the support member becomes large in order to process the reaction force of the material.

  In view of the above circumstances, the present invention can obtain high rigidity without damaging the scenery from the inside and outside of the building with a simple structure, and can reduce the deformation of the wall surface and the cross-sectional area of the member that supports the wall body. An object is to provide a wall support structure.

  In order to achieve the above object, the wall support structure according to claim 1 of the present invention is provided with a plurality of vertical cable members having upper and lower ends fixed to the building housing side, and upper and lower ends on the building housing side. A vertical plate-like vertical beam member fixed to the vertical cable member is disposed between the vertical cable members, and a supporting means for supporting the wall body is fixed to the vertical cable member and the vertical beam member. A transverse cable member fixed and crossing the longitudinal beam member is fixed to the longitudinal beam member.

  A wall support structure according to claim 2 of the present invention is characterized in that, in claim 1 described above, the support means is fixed to the lateral cable member.

  The wall support structure according to claim 3 of the present invention is the wall support structure according to claim 1 or 2, wherein the plate surface of the vertical beam member is provided with a rib member in a mode along the longitudinal direction of the vertical beam member. A square steel material is provided on the edge of the vertical beam material in a mode along the longitudinal direction of the vertical beam material.

  A wall support structure according to a fourth aspect of the present invention is the wall support structure according to any one of the first to third aspects, wherein the support means supports a corner of the wall having a rectangular plate shape. The vertical cable member and the vertical beam member are arranged along a joint portion of the wall body.

  According to the wall support structure of the present invention, a vertical beam member is disposed between a plurality of vertical cable members arranged side by side, and the wall member is supported by a support means fixed to the vertical cable member and the vertical beam member. As a result, even when a large wall surface is constructed, the vertical beam material and the horizontal cable material suppress deformation of the wall surface against the wind and high rigidity can be obtained. The cross-sectional area of the member that supports the body can be reduced. Further, since the horizontal cable member is fixed to the vertical beam member, the vertical cable member can be buckled with the horizontal cable. Furthermore, the supporting force of the wall body can be improved by fixing the supporting means to the lateral cable member.

  Further, by providing the rib material and the square steel material along the longitudinal direction of the vertical beam material, the rib material and the square steel material can prevent the vertical beam material from buckling.

  Further, the supporting means supports the corners of the rectangular wall-shaped wall body, and at least the vertical cable material and the vertical beam material are disposed along the seam portion of the wall body, so that the wall body is made of glass. In this case, the vertical cable material and the vertical beam material are not conspicuous when viewed from the outdoor side of the wall body, so that the landscape can be improved. Furthermore, on the indoor side, there are only vertical cable members and horizontal cable members that are steel cords, and long plate-like vertical beam members, so that the landscape on the indoor side can be improved.
