Description

  The present invention relates to an attachment structure and an exterior structure of a holding member that holds an exterior material for constructing an exterior surface or a support material that supports an upper exterior structure.

  Conventionally, in order to construct an exterior surface (roof surface), a holding member for fixing or retaining the exterior material (roof material) is bonded to the underlying structural material by fastening such as bolts or welding. After that, the exterior material (roof material) was laid by laying a heat insulating material or the like as necessary. That is, the mounting strength and stability of the exterior surface (roof surface) are greatly influenced by the mounting stability of the holding member and the structural material.

However, when the holding member is fixed to the structural material by fastening with a bolt or the like, it is necessary to previously provide a hole for allowing the bolt or the like to pass through the structural material. Since it is located on the back surface (lower surface side of the flange), workability was extremely poor.
In addition, when fixing the holding member to the structural material by welding, more specifically, marking is performed on the fixing portion of the structural material, and the holding member is welded and fixed to the marking line. When a deviation occurs with respect to the ink marking line at the time, the position is displaced and the working width is changed. As a result, there is a problem in that the exterior material is not assembled correctly.

  The present invention has been proposed in view of the above, and is a mounting structure for a structural member having an upper flange portion and a holding member erected on the upper flange portion. The structural material includes an upper flange portion and the upper flange portion.

An attachment structure characterized by having a holding portion for holding a support material, and the upper flange portion of the structural material and the attachment portion of the holding member are attached by two means of locking and fixing, and The present invention relates to an exterior structure including the mounting structure.

  As described above, the mounting structure and the exterior structure of the present invention lock the locking portion of the holding member to the structural material, so that the work process at the site is greatly reduced and the workability is extremely good. That is, when fixing the holding member by fastening with a bolt or the like, it is not necessary to position the fastening tool on the back surface of the structural material while adjusting the position as in the prior art. It can be fastened, and even when the holding member is fixed by adhesion by welding or the like, there is no need to perform ink marking as in the prior art, it can be fixed at an appropriate position, and the assembly of the exterior material is poor. There is no risk of it happening.

  When the holding member has a restricting portion that comes into contact with the vertical piece of the structural material, or the holding member is provided with an engaging portion and a restricting portion that engages with the engaged portion by providing the engaged portion on the structural material. In this case, the position can be regulated more stably than when locking only with the locking part, the movement in the left-right direction is restricted, the work is not shifted in the width direction during the fixing work, and the work is performed properly. It can be performed.
