Abstract

PROBLEM TO BE SOLVED: To facilitate work by forming a slit on one end of a rod, housing turnably a locking piece in this slit with a pin and supporting the rod in such a fashion that the center of the gravity of the locking piece may be deviated to the tip of the rod. SOLUTION: A slit 12 is provided in the longitudinal direction of one end of a rod 11 where a locking piece 13 is housed in the slit 21, thereby forming panel mounting hardware 10, which is turnably supported on a tongue piece 11a of the rod 11 with a pin 14. The locking piece 13 is positioned so that the center of gravity may be deviated to the tip of the rod 1 with the pin 14. A male screwed area 15 is formed on the other end of the rod 11. Then, an insertion hole of the panel mounting hardware is penetratingly bored in the panel. A washer 20 and a nut 30 are engaged, thereby inserting the rod 11 housed in the slit 12 into the insertion hole. The locking piece 13, which has reached a desired position is turned at 90 deg., thereby fastening the nut 30 and placing a lower stage surface of the locking piece in contact with a beam. It is, therefore, possible to facilitate placement work of the panel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel mounting metal piece which is advantageous for mounting a panel such as a lightweight cellular concrete panel (hereinafter referred to as "ALC panel") to a frame.

[0002]

2. Description of the Related Art When an ALC panel is used as a floor, as shown in FIG. 5, each ALC panel 1 is juxtaposed on a steel beam member 3 so that its corners come into contact with a slab plate 2. Then, the through hole 4 provided in the slab plate 2
The joint rebar 5 is inserted into the joint, and the joint rebar 5 is inserted into the joint groove 6 formed by the concave portions of the ALC panels 1 juxtaposed to each other.
Next, the joint rebar 5 and the ALC panel 1 are integrated by filling the joint groove 6 with the mortar 7 and hardening it. After that, the upper surface of the mortar 7 is flattened so as to be flush with the surface of the ALC panel 1. Thus, ALC
The panel 1 is fixed to the beam steel material 3 through the joint rebar 5 fixed by the mortar 7 and the slab plate 2.

[0003]

In the above conventional panel mounting construction method, it is necessary to weld the slab plate 2 to a predetermined portion on the beam steel material 3. The work of welding the slab plate 2 to the steel beam member 3 is performed by the ALC panel 1
The risk was high because it was done at a high place before the installation of the. Further, welding the slab plate 2 to the correct position largely depends on the skill of the craftsman, and requires skill.

Further, after the mortar 7 is filled, a curing time is required until the mortar 7 is hardened, and during that time, work cannot be performed on the ALC panel.
The efficiency of the C panel laying work was low.

SUMMARY OF THE INVENTION An object of the present invention is to provide a panel mounting hardware which facilitates panel laying work and has high working efficiency.

[0006]

According to the invention of claim 1, a slit is formed at one end of the rod in the longitudinal direction of the rod, and a locking piece is housed in the slit. The pin is rotatably supported in the slit, and the center of gravity of the locking piece is displaced relative to the pin in the direction of the tip of the rod-shaped member to be supported, and a male screw portion is formed at the other end of the rod-shaped member. .

According to the first aspect of the present invention, when the rod-shaped locking piece inserted into the insertion hole of the panel penetrates the panel, one end of the locking piece is rotated by gravity and is attached to the attachment portion of the frame. The panel and the mounting portion of the frame are coupled by engaging with each other and engaging the other end with the back surface of the panel and tightening the nut screwed into the threaded portion.

According to the second aspect of the present invention, a step is provided on the one side mounting surface and the other side mounting surface of the locking piece.

According to the second aspect of the present invention, the lower surface is brought into contact with the mounting portion of the frame, and the upper surface is brought into contact with the back surface of the panel, whereby uniform force can be distributed to both contact surfaces. it can.

According to the third aspect of the present invention, a mark is provided on the end face of the male screw portion to indicate the direction in which the locking piece is attached.

According to the invention of claim 3, the direction of the locking piece can be confirmed from the front side of the panel.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The locking piece of the present invention has a center of gravity so that when the rod-shaped locking piece inserted into the insertion hole of the panel penetrates the panel, it is rotated about 90 degrees by gravity. It's off the pin. In this way, in order to shift the center of gravity of the locking piece from the pin, the shape, weight, position of the pin, etc. of the locking piece may be appropriately determined.

The step formed on the attachment surface of the locking piece may be the same as the thickness of the attachment portion of the frame, but is not necessarily the same.

The mark indicating the mounting state of the locking piece arranged at the end of the threaded portion may have any shape as long as the direction of the locking piece can be confirmed, and a chamfer, a groove or a protrusion may be formed.
You may draw with paint etc.

The panel mounting hardware of the present invention can be applied not only to ALC panels but also to other panels. Further, not only the flange of H-section steel but also a shape that can be sandwiched between the locking portion and the panel, for example, a plate-shaped member can be applied. Further, it can be applied not only to the laying of floors but also to the laying of ceilings and the like, and further to the installation of walls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The panel mounting hardware 10 shown in FIGS. 1 and 2 has a slit 12 at one end of a rod 11 in the longitudinal direction of the rod 11. A locking piece 13 is accommodated in the slit 12, and the locking piece 13 is rotatably supported by the tongues 11a and 11a of the rod-shaped body 11 defining the slit 12 by a pin 14 at an intermediate portion. There is. The center of gravity G (shown in FIG. 3) of the locking piece 13 is displaced from the pin 14 toward the tip of the rod 11. Further, the engaging piece 13 has a notch (lower surface) 13a formed in a small opening in the longitudinal direction, and a step H between the engaging piece 13 and the upper surface 13b corresponds to the thickness of the flange of the beam steel material.

A male screw portion 15 is provided on the other end of the rod-shaped body 11.
Is formed, and a chamfer 16 along the generatrix of the rod-shaped body 11 is formed on a part of the male screw portion 15. The chamfer 16 indicates the direction in which the locking piece 13 is attached.

The panel mounting hardware 10 includes a washer 20 and a nut 30. The washer 20 has a claw 21 on one side and a chamfer 22 on a part of the peripheral surface of the hole.

The panel mounting hardware 10 is used in the following manner to mount the ALC panel 50 to the beam constituted by the H-section steel 40.

First, the ALC panel 50 is provided with a through hole 51 for the panel mounting hardware 10, and a counterbored hole 52 is cut on the panel surface side of the hole 51. Then, as shown in FIG. 3, the washer 20 is fitted to the threaded portion 15, the nut 30 is screwed, and the chamfer 16 of the rod-shaped body 11 in a state where the locking piece 13 is housed in the slit 12 is formed. The panel 50 is inserted into the insertion hole 51 from the front side while facing the H-shaped steel 40. When the locking piece 13 reaches the position shown in FIG. 3, the locking piece 13 is rotated 90 degrees by gravity. Then, when the nut 30 is tightened, as shown in FIG.
The lower surface 13a of the locking piece 13 is a flange 41 of the H-shaped steel 40.
And the upper surface 13b comes into contact with the back surface of the panel 50. Further, the claws 21 of the washer 20 bite into the bottom surface of the countersink hole 52 to prevent the rod-shaped body 11 from rotating.

Mortar is filled in the countersunk hole 52 of the panel 50 thus laid.

[0022]
