Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extrusion-molded outer wall panel having hollow holes along its longitudinal direction.

[0002]

2. Description of the Related Art Generally, an outer wall panel having a hollow hole along its longitudinal direction is known.

Conventionally, when such an outer wall panel is attached to a frame assembly or the like, on the spot, four hollow portions at the four corners of the panel are perforated, Z-shaped clips are attached thereto, and this is attached to the shaft. It was fastened with bolts to the base material attached to the set and fixed by welding.

[0004]

However, in the case of the above-mentioned conventional outer wall panel, there arises a disadvantage that a large number of parts are required for on-site construction when the panel is attached to the frame.

Further, since the hole is formed in the hollow portion, the strength of the outer wall panel is deteriorated.

[0006] The present invention has been made in view of the above circumstances, and provides an outer wall panel and its construction structure capable of improving workability on site without reducing the strength of the outer wall panel. Is intended.

[0007]

An outer wall panel of the present invention for solving the above-mentioned problems is an outer wall panel having a hollow hole along a longitudinal direction, and a screw hole faces a back surface thereof. The insert nut is embedded.
Further, a solid portion is provided in a part of the hollow hole, and an insert nut is embedded in the solid portion. Further, the head portion of the insert nut is embedded so as to protrude from the back surface of the outer wall panel so as to have the same thickness as or slightly smaller than the thickness of the mounting bracket of the outer wall panel.

Further, in the construction structure of the outer wall panel of the present invention for solving the above-mentioned problems, the head portion of the insert nut of the outer wall panel is inserted into the bolt hole provided on one surface side of the fitting having the L-shaped cross section. Both of them are bolted together while the fittings are in contact with the back surface of the outer wall panel so that the head is flush with the fittings or slightly recessed. The other surface side is fixed to the lip portion of the lip groove type steel that constitutes the shaft assembly.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an outline of a construction structure of the outer wall panel 1, and FIG. 2 shows a sectional view in which the outer wall panel 1 is fixed to a frame set 5.

That is, the outer wall panel 1 is formed by embedding the insert nut 3 in the extrusion molded panel 2 having the hollow hole 20 provided along the longitudinal direction.

The extrusion-molded panel 2 is manufactured by extrusion molding, and a plurality of hollow holes 20 which are continuous in the longitudinal direction are provided inside the extrusion-molded panel 2 at appropriate intervals in the width direction. Further, a solid portion 21 in which the cement material forming the extrusion molded panel 2 is in a solid state is formed at a position of the second hollow hole 20 from both sides in the width direction. The solid portion 21 is not limited to the position of the second hollow hole 20 from both sides in the width direction. Further, the cement material does not need to be in a solid state over the entire hollow portion 20, and the cement material may be in a solid state in the hollow portion 20 only at a position where the insert nut 3 is embedded. However, when embedding the insert nut 3 along the same longitudinal direction as the direction of the hollow portion 20 as in the present embodiment, it is better to make the cement material in a solid state over the entire hollow portion 20 to form the extrusion molded panel 2. It is preferable because it can be easily molded by simply changing the mold (not shown). In addition, when there is a sufficient space between the adjacent hollow portions 20, the solid portion 21 is not formed,
The insert nut 3 is provided in the gap between the hollow portions 20.
May be buried.

As shown in FIG. 3, the insert nut 3 has a female screw 31 formed on a cylindrical inner peripheral surface thereof and a male screw 32 formed on an outer peripheral surface thereof. Further, the head portion 33 is formed in a hexagonal brim shape. This insert nut 3 is a solid portion 2 on the back side of the extrusion molded panel 2.
A pilot hole (not shown) is previously drilled at the position 1 and screwed into the pilot hole to be embedded in the extrusion molded panel 2. This embedding operation can be performed more easily by screwing in by using the hexagonal collar-shaped head portion 33 than by screwing in by using the female screw 31 on the inner peripheral surface. Since the insert nut 3 is made of a cement-based material such as the extrusion molded panel 1, it is necessary that it is easy to screw in, does not damage the extrusion molded panel 1 at the time of screwing, and has a small reduction in pull-out strength. Become. Therefore, as the insert nut 3,
It is preferable in terms of workability and pull-out strength to use the insert nut 3 of the double-threaded screw in which the male screw 32 on the outer peripheral surface is composed of two types of screw threads having different angles and heights.

The outer wall panel 1 constructed in this way
Is fixed to the frame assembly 5 with bolts 6 via the receiving metal fitting 4a and the joining metal fitting 4b.

Of these, the receiving fitting 4a is formed in an L-shaped cross section, and a bolt hole 40 is provided on one surface thereof. The metal fitting 4a is fixed by bolts 6 by abutting the bolt holes 40 with the insert nuts 3 embedded in the lower end portion of the outer wall panel 1.

On the other hand, the joint metal fitting 4b is formed in an L-shaped cross section, and a long hole-shaped bolt hole 40 is provided on one surface of the joint metal fitting 4b. A locking piece 41 to be drawn is provided. Then, the bolt 6 is fastened in a state where the locking piece 41 is inserted in the groove portion of the lip groove type steel 50 constituting the shaft assembly 5, thereby sandwiching the lip portion between the locking piece 41 and the joint metal fitting 4b. As a result, the joint fitting 4b is fixed to the shaft assembly 5.

The metal fitting 4a is attached to the lower side 5 of the shaft assembly 5.
The outer wall panel 1 is brought into contact with the frame assembly 5 so as to be placed on a. In this state, the bolt hole 40 of the joint metal fitting 4b and the insert nut 3 of the outer wall panel 1 are aligned with each other, and the bolt 6 is tightened to attach the outer wall panel 1 to the shaft assembly 5.

At this time, as shown in FIG. 4, the thickness of the head portion 33 of the insert nut 3 is set to be equal to or slightly smaller than the thickness of the receiving fitting 4a and the joining fitting 4b. . As a result, it is possible to prevent the insert nut 3 embedded in the outer wall panel 1 from being pulled out from the outer wall panel 1 by tightening the bolt 6, and attach the outer wall panel 1 to the shaft assembly 5.

In the present embodiment, the extrusion molded panel 2 is provided with hollow holes 20 having a substantially square cross section at equal intervals, but the hollow holes 20 are limited to those having a substantially square cross section. Moreover, the intervals between the hollow holes 20 are not limited to the uniform intervals. For example, as shown in FIG. 5, an extrusion molded panel 2 in which hollow holes 20 having different sizes are provided in a certain repeating unit may be used.

Further, the outer wall panel 1 may be provided with an opening 22 as shown in FIGS. 6 and 7. However, in this case, since there is a concern that the strength is reduced due to the provision of the opening 22, the reinforcing steel material 7 is inserted into the hollow portions 20 located on both sides of the opening 22 and the screws 71 are provided.
It is preferable to reinforce it by fixing it with or by attaching a long plate-like reinforcing steel plate 8 to the portions located on both sides of the opening 22.

[0021]

As described above, according to the present invention, since the insert nut is embedded in the outer wall panel in advance in a factory or the like, the wall panel is processed on site for joining to the frame. There is no need, and the installation work can be done easily.

Further, the hollow outer wall can be easily extruded and joined to the shaft assembly simply by bolting the insert nut embedded in the outer wall panel and the mounting metal fitting fastened to the shaft assembly. There are few parts to bear, and the construction cost can be reduced.

Further, by providing a solid portion in a part of the hollow hole and embedding an insert nut in this solid portion, structural weakness is eliminated, the strength of the joint portion is increased, and the wind pressure resistance and impact resistance are improved. Excellent effect is obtained.

Further, according to the construction structure of the present invention, since the head portion of the insert nut is fixed with the bolt so that the head portion of the insert nut is flush with or slightly recessed from the mounting member, the embedded insert nut is pulled out by fixing the bolt. The outer wall panel can be securely fixed to the frame without worrying about being pulled in the direction.
