Description

The present invention relates to a structure for attaching an accessory such as a signboard to an outer wall of a building.

Conventionally, as a structure for attaching an accessory such as a signboard to the outer wall of a building, there is a structure in which the accessory is fixed to the outer wall with a bolt (see, for example, Patent Document 1). In this structure, the accessory is attached to the outer wall by providing a bolt insertion hole in the attachment portion of the accessory, inserting the bolt through the bolt insertion hole, and sandwiching the attachment portion between the head of the bolt and the outer wall.

By the way, as the outer wall, there is a panel type outer wall, for example, an outer wall composed of panels that are continuous in the vertical and horizontal directions. In this outer wall, the panels are independently attached to the skeleton of the building so as to be able to follow the deformation of the skeleton at the time of an earthquake (see, for example, Patent Document 2). By doing so, damage to the panel during an earthquake is prevented. As a specific mounting structure, the panel is mounted on the skeleton of the building by mounting O-bolts projecting from the center of the upper end portion and the center of the lower end portion of each panel to the hardware protruding from the beam.

When the accessories were mounted across the two panels of such a panel-type outer wall, the accessories were simply bolted to each of the two panels.

However, with such an accessory mounting structure, when two panels move independently due to an external force such as an earthquake, the accessories not only try to follow the movement of one panel but also the other. It also tries to follow the movement of the panel. Therefore, as a result, there is a problem that a force is applied in the direction of deforming the accessory, and the accessory or the panel may be damaged.

The present invention has been made in view of the above, and even when an accessory is attached across two panels attached to a building frame independently of each other, the panel or the panel or an external force such as an earthquake may be used. It is an object of the present invention to provide an accessory mounting structure in which accessories are less likely to be damaged.

In order to solve the above-mentioned problems and achieve the object, the accessory mounting structure according to the present invention is attached to an outer wall formed by mounting a plurality of panels independently on a building frame, straddling the plurality of panels. An accessory mounting structure for attaching an object by a fastener, the fastener having a shape protruding from the panel, the accessory having a fastener insertion hole, and the fastener being inserted into the fastener insertion hole. The fastener insertion hole is held in the fastener in a state of being inserted into the fastener, and the fastener of a panel other than one of the plurality of panels is inserted. It is characterized by having an inner diameter larger than that of the fastener insertion hole through which the fastener is inserted.

In the accessory mounting structure according to the present invention, the fastener insertion hole may be a circular hole.

In the accessory mounting structure according to the present invention, the panel has a panel-side holding portion, the fastener has a holding portion on the tip side in the protruding direction, and the accessory has a panel-side holding portion. It is preferable that it is sandwiched between the sandwiching portion and held by the fastener.

According to the above configuration, among the plurality of panels for attaching the accessories, the fasteners provided in one panel have a fastener insertion hole through which the fasteners provided in the panels other than one panel are inserted. Since it is larger than the fastener insertion hole that is inserted, there is a gap in the fastener insertion hole through which the fastener provided in the panel other than one panel is inserted, and an external force such as an earthquake occurs. Even if a plurality of panels move independently when the stress is applied, the displacement at that time can be absorbed in the gap, and the panel or the accessory can be prevented from being damaged.
