Description

  The present invention relates to an outer wall structure formed using a plurality of panels and a construction method thereof.

  Conventionally, when constructing an outer wall by laminating metal panels horizontally, first, the vertical trunk edge, which is the foundation in steel construction, is fixed to a frame such as a beam or slab, and then installed. A panel is attached to the outside of the trunk edge to form an outer wall. Further, a wind resistant beam extending in a direction (horizontal direction) orthogonal to the vertical trunk edge is installed inside the vertical trunk edge to enhance the wind resistance of the outer wall.

In recent years, there has been proposed a method in which a panel and a vertical trunk edge are integrally combined to form a unit and a unitized panel unit is installed. In this method, the panel unit is formed in advance and the mounting bracket is attached to the end of the slab, and the panel unit is disposed on the side of the slab, and the vertical trunk edge and the mounting bracket are joined, This is a method of forming an outer wall. (For example, refer to Patent Document 1).

  However, in the former method for constructing the outer wall structure described above, since the panels are attached one by one, there is a problem that a considerable work period is required when attaching a large number of panels. In addition, since it is difficult to increase the installation accuracy of the vertical trunk edge, there is a problem that an attachment piece may be required at a joint portion between the panel and the vertical trunk edge, which causes a cost increase.

  In the latter conventional outer wall structure construction method described above, when the panel unit is placed in a floating state, the weight of the panel unit is applied to the end of the slab provided with the mounting bracket, and the overhanging slab is a panel. There is a problem that the structure must be able to support the weight of the unit, and the amount of reinforcing bars of the slab increases, or the slab thickness increases, resulting in an increase in cost.

In addition, since the panel and the trunk edge are joined in advance, an attachment piece for absorbing the accuracy of the joining portion between the panel and the trunk edge becomes unnecessary, and the cost can be reduced. Furthermore, since the panel unit is attached to the pillar via the bracket, the panel unit does not have a weight on the slab, and it is not necessary to increase the amount of reinforcing bars of the slab.

  In the outer wall structure according to claim 2 of the present invention, a vertical adjustment means for adjusting the height of the bracket is provided at a joint portion between the bracket and the column, and a joint portion between the bracket and the wind-resistant beam is provided at the joint portion.

Of course, the base end may be fixed in a reinforced concrete column, or the base end of the bracket may be joined to a gusset plate fixed in the reinforced concrete column, and the bracket may be stretched over the reinforced concrete column. It may be a steel reinforced concrete column.

  In the above-described embodiment, the brackets 10 and 11 are provided in a pair of upper and lower sides with the joint portion 4 interposed therebetween, and the upper and lower brackets 10 and 11 are respectively attached to the upper and lower ends of the panel unit 9. In the present invention, a pair of upper and lower brackets may be provided between the joints on the upper and lower floors. The bracket may be attached not only to the upper and lower ends of the panel unit, but also to the middle part of the panel unit, or the bracket may be attached to either the upper or lower end of the panel unit. Good.

  In the above-described embodiment, the wind resistant beams 14 and 15 are joined to the vertical trunk edge 12. However, the present invention may be applied to the case where the wind resistant beam is joined to the horizontal trunk edge 13, and further to the panel. It may be joined.
