JP-A-2002-138625

In the anchor hardware described in Patent Document 1, since the rising portion is in a rising posture in which the rising portion is raised from the mounting portion in the back direction of the finishing material, the amount of protrusion of the finishing material from the back surface portion is large. The size of the finishing material to which the anchor hardware is attached is increasing. Therefore, when the finishing material to which the anchor hardware is attached is transported to a factory or the like where the cement-based material is placed, the transportation work becomes troublesome, which causes an increase in transportation cost.

In view of this situation, the main subject of the present invention is to provide an anchor hardware capable of improving the bonding strength between the finishing material and the cement-based material while simplifying the transportation work and reducing the transportation cost. At the point.

The first characteristic configuration of the present invention is an anchor hardware for a finishing material that can be attached to the back surface of the finishing material.
A mounting portion to be attached to the back surface portion of the finishing material and a rising portion extending from the mounting portion are provided.
The rising portion was bent toward the front side of the finishing material in the front and back directions of the finishing material so as to approach the back surface portion of the finishing material by bending at the folding line portion formed between the mounting portion and the rising portion. The point is that the posture can be freely changed from the lying posture to the standing posture in which the finishing material is raised from the mounting portion to the back side of the finishing material so as to be separated from the back surface portion of the finishing material.

According to this configuration, when the finishing material is transported with the anchor hardware attached, the size of the finishing material to which the anchor hardware is attached can be reduced by keeping the rising portion in the inverted posture. Therefore, when the cement-based material is transported to a factory or the like where it is placed, the transportation work can be facilitated and the transportation cost can be reduced. When a cement-based material is placed on the back surface of a finishing material in a factory or the like, the rising portion of the rising posture is buried in the cement-based material by changing the posture from the lying posture to the rising posture. It is possible to integrate the finishing material and the cement-based material while improving the bond strength in the state. Moreover, to change the posture from the lying down posture to the standing posture, it is only necessary to bend it along the polygonal line formed between the mounting portion and the rising portion, and to simplify the posture changing work of the rising portion. Can be done.

The second characteristic configuration of the present invention is that a posture holding portion for holding the rising portion in the standing posture is provided.

According to this configuration, when the cement-based material is placed on the back surface of the finishing material, the rising portion can be held in the rising posture by the posture holding portion, so that the rising portion is made of the cement-based material. The finishing material and the cement-based material can be integrated in a state of being properly buried.

In the third characteristic configuration of the present invention, the rising portion is arranged at both ends of the mounting portion in a state where the broken line portion is formed between the rising portion and the mounting portion.
A point is that a connecting portion is provided which is raised from the mounting portion to the back side of the finishing material in the front and back directions of the finishing material in a state where the ends of the polygonal line portions in the rising portions on both sides are connected to each other.

According to this configuration, by providing a connecting portion that is raised from the mounting portion to the back side of the finishing material in the front and back directions of the finishing material in a state where the ends of the broken line portion are connected to each other, when the rising portion is bent at the broken line portion The mounting portion and the like can be reinforced, and the bending work at the polygonal line portion can be easily performed.

The fourth characteristic configuration of the present invention is that the connecting portion is provided with a posture holding portion that holds the rising portion in the standing posture.

According to this configuration, since the connecting portion also serves as the posture holding portion, the configuration can be simplified. Moreover, both the connecting part and the starting part in the starting posture have the same posture in which they are raised from the mounting part to the back side of the finishing material in the front and back directions of the finishing material. Therefore, for example, a member extended from the connecting part is simply extended. The structure itself for making the connecting part also serve as the posture holding part is also a simple structure, such as forming the posture holding part in.

The fifth characteristic configuration of the present invention is an elastic sealing material that is elastically displaceable and is surrounded by the rising portion in a standing posture and the connecting portion on the back side of the finishing material in the front and back directions of the finishing material from the mounting portion. The point is that the filling space for use is freely formed.

According to this configuration, a filling space for the elastic sealing material is formed on the back side of the finishing material in the front and back directions of the finishing material from the mounting part by using the rising portion and the connecting portion in the rising posture. It is possible to form a filling space for an elastic sealing material while simplifying the configuration and reducing the cost without requiring a dedicated member for forming.

By filling this filling space with an elastic sealing material, an elastic sealing material capable of elastic displacement can be interposed between a fastener such as a screw for attaching the mounting portion to the back surface portion of the finishing material and a cement-based material. it can. As a result, the fastener and the cement-based material are not fixed in a displaceable manner, and displacement occurs between the finishing material and the cement-based material due to heat shrinkage of the finishing material and drying shrinkage of the cement-based material. However, the displacement can be absorbed by the fastener moving with respect to the cement-based material via the elastic sealing material.
