DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a panel such as lightweight cellular concrete (hereinafter referred to as ALC) is attached to an outer wall of a building as a vertical wall, and in particular, a wide panel having a width of 90 cm or more is used. This provides a structure suitable for mounting on a scaffold.

[0002]

2. Description of the Related Art Conventionally, various structures for mounting a wide panel such as an ALC plate as an outer wall of a building have been proposed. For example, as shown in FIG. 3, an upper ruler angle 3 and a lower ruler angle 1 are formed on the upper and lower surfaces of the upper flange 2 of the beam 1 of the building.
8 is welded and fixed, and a receiving bracket 15 is welded to the upward ruler angle 3 toward a connecting portion of the adjacent upper panel 4a to support the lower end of the panel 4a. A vertical reinforcing bar 17 whose lower end is welded to the receiving bracket 15 is disposed in a groove 16 on both sides of the upper panel 4a. The groove 16 is filled with cement mortar and fixed.
Further, as shown in FIG. 3, the upper end of the panel is provided with a bolt 19 penetrating through holes formed in the vicinity of both upper ends in the width direction. The downward ruler angle 18 is clamped. This structure is a so-called slide method in which the lower end of the panel is fixed to the skeleton and the upper end is slightly movable in the horizontal direction with respect to the skeleton, and the quake resistance is also considered.

In this method, however, the work of welding the downward ruler angle 18 and the work of attaching the slug plate 20 are behind the beam 1, so that the workability is poor, and the fitting 15 and the reinforcing bar 17 are welded, There are many on-site operations such as repair work and filling with cement mortar,
There was a problem that the construction period was long. Further, there is a problem that a panel in which a metal fitting for bolt locking is embedded cannot be used.

As another structure, Japanese Patent Application No. 63-85867 filed earlier by the present applicant (see FIGS. 4 and 5)
Then, a ruler metal 21 is fixed to the beam 1 near both ends in the width direction of the panel, and a snap fastener 22 attached to the upper end of the lower panel 4 is inserted into a notch of the ruler metal 21. Then, the insertion hardware 23 having an L-shaped cross section is inserted in the opposite direction and fixed. In addition, a height adjusting hardware 24 having a U-shaped cross section is fastened to the insertion hardware 23, and the height adjusting hardware 24 is
The upper panel 4a is bolted to the embedded metal 27 of the panel 4a so as to sandwich the vertical portion of the step-shaped weight receiving metal 25.
And fasten it. At this time, the lower end of the upper panel 4a is supported by the weight receiver 25, and the bolt 28 on the top of the weight receiver 25 is further turned to raise and lower the weight receiver 25 so that the height of the upper panel 4a can be adjusted. There is something.

However, in this structure, since the embedded metal 27 bears the rotational force and wind pressure due to the weight of the panel 4a, large strength is required depending on the weight and area of the panel. In addition, there is a problem that costs and troubles are required because the shape of the mounting hardware is complicated and many. Further, as another structure, as shown in FIG. 6, the tip end of an armature metal piece 22 attached to the upper end of the lower panel 4 and the upward ruler angle 3 fixed to the beam 1 are cross-sectioned as shown in FIG. The metal piece 29 is clamped by a metal fitting 29, and the metal piece 29 is further clamped by an armature metal piece 30 attached to the lower end of the upper panel 4a. The weight of the upper panel 4a is separately set by the upward ruler angle 3.
Some are supported by an angle (not shown) that is fixed to the shaft.

However, in this structure, since only the tip of the metal fastener 22 attached to the upper end of the lower panel 4 is in contact with the ruler angle 3, a large wind pressure applied to the panel 4 is applied to the metal fastener 22. In such a case, it is necessary to increase the width and thickness of the hardware, which is costly and troublesome. Furthermore, to form these conventional outer wall structures, it is necessary to temporarily provide a scaffold outside the building and work together inside and outside the panel, and since there are many welding operations on site, many skilled workers are required. Needed, there were safety issues, and a lot of space was needed around the building.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an outer wall mounting structure which does not require temporary installation of a scaffold or welding on site and which is easy to construct.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an outer wall panel mounting structure for locking an outer wall panel vertically connected to a ruler angle screwed to an upper edge of a beam. In the above, the vertical lower end of the self-weight receiving bracket having a horizontal T-shaped cross section screwed to the lower end of the panel is screwed to an upward ruler angle screwed to the upper edge of the beam, and screwed to the vicinity of the upper end of the panel. In this case, a downward ruler angle in which the attached mounting bracket is screwed to the upper edge of the beam is sandwiched. The horizontal joints of the vertically arranged outer wall panels are positioned lower than the horizontal parts of the dead weight fittings, and water is stopped by a double gasket over the entire length.

[0009]

By configuring the outer wall panel mounting structure as described above, even when the upward and downward ruler angles are attached to the beam, the self-weight receiving bracket is screwed to these ruler angles, or the mounting bracket is mounted. Even when fastening, work can be performed only on the indoor side, and on-site welding is unnecessary. In addition, the horizontal joint is located below the horizontal part of the weight holder,
Water is stopped by a double gasket over the entire length, so filling with caulking material is unnecessary and it can be completely waterproofed.
Since there is no work from the outside, temporary construction of the scaffold is not required, and work safety is improved.
