DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel mounting apparatus used when mounting a wall panel such as a precast concrete panel to a building.

[0002]

2. Description of the Related Art FIG. 5 shows a state in which a wall panel is a precast concrete panel (hereinafter referred to as "PC panel") 1 and the PC panel 1 is mounted on a building.

[0003] This PC panel 1 has been
The upper side is supported by the beam 2 of the building using the mounting bracket A proposed in Japanese Patent Application No. Hei 8-23212, and the lower side is a conventional mounting device (hereinafter referred to as "mounting device") b of the PC panel 1. And attached to the beam 2 of the building.

A detailed description of the mounting bracket A is given to the above-mentioned prior application and the like. The mounting bracket A is formed by implanting a part of a mounting bracket body A 'made of a cast product on the PC panel 1, and mounting the mounting bracket body. A 'is mounted on the beam 2 via a bolt.

The conventional mounting device b comprises an L-shaped anchor bolt 10 and a spherical nut 11 screwed to the anchor bolt 10. The anchor bolt 10 has a spherical washer 12 projecting outwardly welded in advance to a position projecting from the surface of the PC panel 1. The anchor bolt 10 is bound and fixed to the reinforcing bar 1 'of the PC panel 1, and concrete is filled in this state.

[0006] The bolt side of the anchor bolt 10 is provided so as to penetrate a through hole 3a of an L-shaped mounting bracket 3 having one end fixed to the beam 2 of the building.
It is configured such that the spherical nut 11 is screwed via 3.

In FIG. 5, reference numeral B denotes a packing provided between adjacent PC panels 1, and accordingly, each PC panel 1
Are supported by a building (beam) in a form separated from the adjacent PC panel 1. Moreover, since each PC panel 1 is swingably supported by the mounting bracket 1, even if the building itself vibrates due to an earthquake or the like, the PC panel 1 is not adversely affected, and the mounting device b is also spherical. Since the mounting bracket 3 supports the washer 12 and the spherical nut 11, the vibration of the PC panel 1 can be effectively absorbed.

The PC panel 1 shown in FIG. 5 is swingably supported on the beam 2 of the building at the upper side via a mounting bracket A. The mounting bracket A is mounted on the lower side of the PC panel 1. The mounting device b may be provided on the upper side of the PC panel 1 in some cases.

[0009]

However, in the above-mentioned conventional mounting device, the spherical washer is welded to the anchor bolt, so that the manufacturing cost is increased and the anchor to which the most force is applied when the wall panel vibrates. Since the bolt portion has a history of being heated by the welding of the spherical washer, the strength becomes uneven and the quality is inferior.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, a mounting apparatus according to the present invention comprises a wall panel swingably supported by a building via an anchor bolt implanted in the wall panel. An anchor bolt, wherein the anchor bolt is screwed to a body having a spherical surface whose surface located on the surface of the wall panel protrudes outward, and from the center of the spherical surface. It is characterized by protruding.

In order to achieve the above object, the mounting device according to the present invention mounts a wall panel swingably supported on a building to the building via anchor bolts planted on the wall panel. The device, wherein the anchor bolt is formed integrally with a body having a spherical surface whose surface located on the surface of the wall panel projects outward, and
It is characterized by protruding from the center of the spherical surface.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a mounting device a according to an embodiment, FIG. 2A is a view taken along line AA of FIG. 1, FIG. 2B is a view taken along line BB of FIG. FIG. 3 is an enlarged view of a portion A in FIG. Note that the same components as those in FIG. 5 will be described using the same reference numerals, and description of these same reference numerals will be omitted.

The anchor bolt 4 is formed of a well-known hexagonal bolt, and is screwed to a mounting device main body (hereinafter, referred to as “main body”) 5. The main body 5 is made of an integral cast product and has a length of about half the thickness of the PC panel 1.
The inside has a cylindrical shape of space.

As shown in FIG. 2A, a radial projection 5 is provided at an end of the main body 5 located inside the PC panel 1.
are provided so that the contact area with the PC panel 1 can be increased and the coupling force with the PC panel 1 can be increased. Also, PC
An end located on the surface of the panel 1 is formed on a flange-shaped spherical surface 5b projecting outward as shown in FIG.

The positional relationship between the anchor bolt 4 and the main body 5 is such that the anchor bolt 4 is located at the axial center of the main body 5, that is, the anchor bolt 4 projects from the center of the flange-shaped spherical surface 5b. Is configured. The anchor bolt 4 is configured to be screwed to a female screw 5c provided on the projection 5a side of the main body 5.

The female screw 5c is made by tapping after the casting of the main body 1. Depending on the type of the tapping, the thickness of the anchor bolt 4 can be made desired.

The anchor bolt 4 is implanted in the PC panel 1 while being screwed to the main body 5. That is, the main body 5 to which the anchor bolt 4 is screwed is fixed to the reinforcing bar 1 ′ with a binding wire (not shown), and in this state, concrete is filled and implanted in the PC panel 1. In this case, by adjusting the relative position between the anchor bolt 4 and the main body 5, the length of the screw of the anchor bolt 4 protruding from the PC panel 1 can be adjusted.

An anchor bolt 4 protruding from the PC panel 1 is penetrated through a through hole 3a of the mounting bracket 3, and a nut 7 is screwed into the penetrated portion with a spherical washer 6 interposed therebetween. Here, the through hole 3a is formed in a vertically long shape in order to allow a margin for a mounting position between the anchor bolt 4 and the mounting bracket 3.

In the mounting device a having the above structure, the mounting bracket 3 is held between the spherical surface 5a and the spherical nut 6, so that the vibration of the PC panel 1 can be effectively absorbed.

In the case of the L-shaped anchor bolt 10 shown in FIG. 5, the force for fixing the PC panel 1 to the mounting bracket 3 is scattered from the mounting position of the mounting bracket 3, whereas Since the bolts 4 are uniformly distributed around the axis, the bolts 4 can be effectively mounted.

A mounting device a 'shown in FIG. 4 shows another embodiment, in which an anchor bolt 4' and a main body 5 'are integrally formed, for example, made by forging. be able to. As described above, when integrated, the quality can be kept uniform and high, and the mounting device can have high strength.

The mounting devices a and a 'according to the present invention are applicable whether the PC panel 1 is supported on the upper side (see FIG. 5) or the PC panel 1 is supported on the lower side. can do.
