Description

The present invention relates to fixtures and panel mounting structures.

Patent Literature 1 describes a method of attaching an exterior member to a longitudinal furring strip using a pair of self-drilling screws, a hat-shaped mounting metal fitting in cross section, and a pair of nuts.

In this method, a pair of self-drilling screws are passed through the exterior material, and the vertical furring strips hold the mounting base metal fittings so that the pair of self-drilling screws are inserted into the pair of mounting pieces of the mounting base metal fittings, Fix a pair of self-drilling screws with a pair of nuts.

Japanese Patent No. 2647612

By the way, in the method described in Patent Document 1, the exterior material is supported from the front side by small portions such as respective heads of a pair of self-drilling screws.

Therefore, in this method, when a negative pressure is generated on the front side of the exterior material due to the influence of the wind, etc., and the exterior material is pulled toward the front side, the portion of the exterior material that the head of the self-drilling screw comes into contact with is locally damaged. This part may become dented if a load is applied to it.

In this case, a gap is formed between the exterior material pulled to the front side and the pair of mounting pieces of the mounting bracket, and the exterior material is sandwiched and supported by the pair of self-drilling screw heads and the pair of mounting pieces. The state will be canceled, and there is a risk that the strength of attachment of the exterior material to the vertical furring strip will be reduced.

Hereinafter, among the plurality of panels 3, the panel 3 positioned at the top is referred to as panel P1, the panel 3 positioned second from the top is referred to as panel P2, and the panel 3 positioned third from the top is referred to as panel P3. do.

First, the panel P1 is fixed to the base material 1. As shown in FIG. The panel P1 is fixed to the base material 1 by, for example, driving fasteners (not shown) such as screw screws into the base material 1 from the concave streaks 16 at the upper end of the panel P1. In addition, the panel P1 may be fixed to the base material 1 using the fixture 2 .

Next, the panel P2 is placed in a connection position where its upper end is connected to the lower end of the panel P1, and the panel P2 is fixed to the base material 1 using the fixture 2. As shown in FIG.

Specifically, before arranging the panel P2 at the connecting position, the first mounting member 21 is mounted so as to pass through the grooved portion 16 at the upper end portion of the panel P2. In the first mounting member 21, the long plate portion 210 is housed in the grooved portion 16 with respect to the panel P2, a pair of bolts 211 are inserted through the pair of through holes 20, respectively, and the tip portions of the pair of bolts 211 are attached. is attached so as to protrude rearward from the panel P2.

By moving the panel P2 to which the first mounting member 21 is attached from below the panel P1 to above, the panel P2 is arranged at the connection position. The movement of the panel P2 is performed using a lifting device such as a crane. A panel support (not shown) is attached to the panel P2 to support it from below so that the upper end of the panel P2 is exposed, and this panel support is suspended and supported by a suspension device.

The second attachment member 22 is attached to the base material 1 while the panel P2 is arranged at the connection position. The second mounting member 22 is arranged so that the hooking portions 220 sandwich the base material 1 and is hooked on the base material 1 . The parts projecting rearward from the panel P2 are inserted therethrough.

A pair of fasteners 24 are respectively inserted into the pair of through holes 225 of the hooking portion 220 , thereby fixing the second mounting member 22 to the base material 1 . When the second mounting member 22 is fixed to the base material 1, the front surfaces of the pair of insertion portions 221 of the second mounting member 22 and the front surface of the base material 1 are substantially flush with each other.
