DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel mounting bracket and a mounting method used for mounting a panel such as lightweight cellular concrete (ALC).

[0002]

2. Description of the Related Art Referring to FIGS. 8, 9, 10 and 11, FIG.
A conventional panel mounting bracket will be described. A first conventional example shown in FIG. 8 has a hook bolt 51 having a substantially uniform circular cross section and a round washer 5 having a circular hole through which the hook bolt 51 is inserted.
2 and a nut 54 screwed into the male screw 53 of the hook bolt 51. One end of the hook bolt 51 having the male screw 53 is inserted into the through hole 55 a of the ALC panel 55 from the back surface, and one end of the hook bolt 51 is inserted. Insert the round washer 52 on the side, screw the nut 54 into the male screw 53 and turn it.
The hook bolt 51 is temporarily fixed to the panel 55. Next, the ALC panel 55 is placed at a predetermined position on a column (or beam) 56 made of H-section steel, and the hook bolt 51 is rotated to lock the other end of the column (or beam) 56 with the column (or beam) 56. After hooking on the flange 57 and turning the nut 54 to perform final tightening, the hook bolt 51 is fixed to a column (or beam) 56 by welding, and the ALC panel 55 is attached to the column (or beam) 56.

In a second conventional example (Japanese Patent No. 2835485) shown in FIGS. 9, 10 and 11, a deflected plane 59 indicating the direction of a hook 58 is formed at one end to form a male screw 53. A nut 54 is fastened by turning a nut 54 by a non-circular hook bolt 60 having a non-circular cross section and a co-rotating washer 63 having a non-circular hole 62 through which a non-circular cross-sectional portion 61 is inserted and rotating together with the non-circular hook bolt 60. At this time, the rotation of the co-rotating washer 63 is stopped by the stop pin 64 or the stop piece 65 to prevent the rotation of the non-circular hook bolt 60, so that the non-circular hook bolt 60 can be connected to a column (or a beam) without welding. ) 56
And fix the ALC panel 55 to the column (or beam) 56.
It was attached to.

However, in the above-mentioned first conventional example,
When turning the nut 54 to tighten it, the hook bolt 51
However, they do not rotate smoothly. Therefore, in order to prevent such co-rotation, tightening is performed while holding down with hands or tools. Further, in the first conventional example, there is a concern that the hook portion 51 may come off the flange 57 due to the loosening of the rotation of the hook bolt 51 due to deformation of the building or various vibrations after the panel mounting is completed. Although the flange 58 is fixed to the flange, the welding operation itself may be difficult depending on the panel mounting portion, and in such a case, there is a problem that the hook bolt 51 according to the first conventional example is difficult to employ. there were.

In order to avoid such a problem of the first conventional example, a non-circular hook bolt 60 according to a second conventional example has been proposed. Is generated when the non-circular hook bolt 60 is manufactured, and the general round washer 52 cannot be used as the washer, and a special co-rotating washer 63 needs to be preliminarily processed and prepared. There is such a problem. Further, since the external thread 53 forms the uneven plane 59, the amount of thread is reduced by cutting, so that when the screws are tightened, the frictional resistance between the threads tends to be small, and the deformation of the building after the panel mounting is completed. And various vibrations,
In comparison with the first conventional example, the nut 54 tends to loosen in rotation. Further, in the second conventional example, when the nut 54 is turned and fastened, the stop pin 64 or the stop piece 65 is used.
It is necessary to stop the rotation of the co-rotating washer 63, but in the case of the locking pin 64, the construction time is increased and the locking pin 6
4 may be forgotten to be installed. On the other hand, in the case of the stopper piece 65, although the construction time is simple, the fixing force to the panel is generally weaker than that of the stop pin 64, and the building after the panel installation is completed. When the rotation of the nut 54 is greatly loosened due to deformation or various vibrations, the fixing of the co-rotating washer 63 to the panel may be disturbed depending on the dimension setting such as the height and position of the stopper 65.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to prevent a right-handed screw (left-handed screw) from being loosened even if it is not fixed by welding, so that a hanging portion does not come off from a building frame side. An object of the present invention is to provide a mounting bracket and a mounting method. Further, it is an object of the present invention to provide a panel mounting bracket and a mounting method that also prevent co-rotation of a screw member.

[0007]

According to a first aspect of the present invention, a shaft having a right-handed screw (or left-handed screw) at least at one end is integrally formed with the shaft at the other end. Forming a hanging part or a hanging part whose rotation is restricted, with the shaft part as the axis of rotation, taking the direction of the hanging part as the starting point of rotation, and turning counterclockwise in the direction of viewing the hanging part from the shaft part A panel mounting bracket characterized in that a contact piece oriented in a direction of (or clockwise) 20 degrees to 160 degrees is formed on the other end side of the shaft portion.

[0008] A second aspect of the present invention is the second aspect.
According to the invention, a screw member is screwed and fastened to a right-hand screw (or left-hand screw) engraved on one end of the shaft, and the other end of the shaft is integrated with the shaft or restricted from rotating. The hook formed in this state is hooked to the skeleton side flange, and the shaft is used as the axis of rotation and the direction of the hook is used as the starting point of rotation. This is a panel mounting method characterized in that a contact piece formed on the other end side of the shaft portion in a direction around 20 to 160 degrees is brought into contact with an end face of the skeleton side flange.

Since the panel mounting bracket of the first invention and the panel mounting method of the second invention using the panel mounting bracket are configured as described above, the screw at one end of the shaft portion is screwed by the screw member when the panel is mounted. When tightening, at the other end of the shaft,
From one end side of the shaft portion to the other end side, a contact piece formed in a direction of 20 degrees to 160 degrees counterclockwise (clockwise) with the direction of the hook portion as the starting point of rotation is formed on the end face of the body side flange. If the right-hand screw (left-hand screw) tries to loosen due to contact,
The contact piece is pressed against the end face of the body side flange and resists, so that the right-hand screw (left-hand screw) can be prevented from loosening, so that the rotation of the shaft can be prevented. Also, it is possible to prevent the rotation of the hooked portion, and compared with the first conventional example, the work of welding the hooking portion to the building frame side is eliminated, and the construction work can be simplified.

Further, the panel can be mounted using the general-purpose round washer 52 without preparing a special co-rotating washer 63 in advance as in the second conventional example. Also,
There is no time and effort required to form the eccentric plane 59 in the external thread 53 in advance, and therefore, the amount of thread is not reduced by cutting, so that when tightening the screw, the frictional resistance between the threads can be as high as the conventional example. Rotational loosening of the nut 54 does not easily occur due to deformation of the building or various vibrations after the panel mounting is completed. Further, there is no need to perform the work of stopping with the locking pin 64.

As described above, the first and second inventions can prevent the right-handed screw (left-handed screw) from being loosened without being fixed by welding. A panel mounting bracket and a mounting method that do not come off. But,
In some cases, such as when the screw member is loosely tightened or when the frictional resistance between the panel and the screw member is particularly small, the right-hand screw (left-hand screw) and the screw member that has been screwed together rotate the shaft part. There is a possibility that the rotation of the locking portion, which is integrated with the shaft portion or the rotation of which is restricted, also rotates and may come off from the skeleton-side flange, and in any case, it is not perfect.

Therefore, the third invention and the fourth invention according to the present invention.
It is an object of the present invention to provide a panel mounting bracket and a mounting method that prevent the screw members from rotating together, in addition to the configurations of the first and second inventions. According to a third aspect of the present invention, there is provided the third aspect of the present invention, wherein one end of the shaft portion of the screw member or the panel mounting bracket is fixed non-rotatably to the panel. Panel mounting method.

Since the panel mounting method of the third invention is configured as described above, one end of the screw member or the shaft of the panel mounting bracket is fixed to the panel so that it cannot rotate, so that a right-handed screw (left-handed screw) is used. The screw member screwed and fastened does not rotate together, so the shaft portion does not rotate, and the locking portion that is integral with or restricted from rotating does not rotate, so it comes off from the body side flange There is no such thing. According to a fourth aspect of the present invention, in the panel mounting bracket according to the first aspect, a claw portion penetrating into the panel is formed in the contact piece so as to protrude toward the shaft portion. is there.

The panel mounting bracket according to the fourth aspect of the present invention is constructed as described above. Therefore, when the screw on one end of the shaft portion is screwed and fastened by the screw member when the panel is mounted, the claw portion projected from the contact piece is formed. Penetrates into the panel, so that the shaft does not rotate, and the locking part, which is integral with or restricted from rotating, does not rotate, so that it does not come off from the skeleton side flange. In addition, although it is common to 1st invention-4th invention,
When an indication indicating the direction of the hook portion is formed on one end side of the shaft portion,
When screwing a screw member onto the screw of the shaft, the direction of the hook can be checked from the front side of the panel. This is more preferable because it can be confirmed that the part is hung on a pillar or a flange of a beam on the building frame side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 6, an embodiment will be specifically described as an example of a panel mounting bracket and a mounting method according to the present invention. FIG. 1 is a perspective view showing a panel mounting bracket according to a first embodiment of the present invention. FIG. 2 is a perspective view of the first embodiment of the present invention using the panel mounting bracket according to the present invention.
It is a perspective view which shows the panel mounting method which mounts an LC panel as a floor slab. FIG. 3 is a partially broken side view for explanation showing the procedure of the panel mounting method in the case of FIG. 2 in order. FIG. 4 shows a second embodiment of the panel mounting fitting according to the present invention, showing the form of the hook and the contact piece. FIG. 5 is a panel mounting bracket according to a fourth embodiment of the present invention in which a female screw is used for a shaft. FIG.
It is the 5th Example which shows another form regarding the direction of the contact piece in the panel mounting bracket according to the present invention.

In FIG. 1, the panel mounting bracket 1 is provided with a thread 4b on one end 4 of the shaft 2 with a right-hand thread, while the other end 5 of the shaft 2 is From the one end 4 toward the other end 5, approximately 9 counterclockwise from the starting point of rotation of the hook 3.
The contact piece 6 is provided in the 0 degree direction θ. In the first embodiment, the hooking part 3 is formed by bending the shaft part 2 and integrally formed, and the main body of the panel mounting bracket 1 is a hook-shaped bolt. The contact piece 6 is formed of plastic and is fitted into the other end 5 of the shaft 2 in a non-rotatable manner. That is, in the present invention, it is important that the contact piece 6 is restrained so as not to rotate with respect to the shaft portion 2. Are not included. With this configuration, the screw portion 4b on one end 4 of the shaft portion 2 is formed.
On the other hand, when the screw member 8 is screwed and fastened, the screw member 8 is tightened by turning the right screw. However, when the screw portion 4b is about to be loosened, the hook portion 3 moves from the one end 4 to the other end of the shaft 2. He is trying to loosen while turning clockwise toward. However, as will be described later with reference to FIG. 2, according to the mounting state of the panel mounting bracket 1, the contact piece 6 fitted in the shaft portion 2 in a non-rotatable state is engaged with the locking portion 3. The screw portion 4b does not come loose because it comes into contact with the stopped end surface 11a of the skeleton side flange 11 to restrict rotation. Since the contact piece 6 only needs to be in contact with the end face 11a of the skeleton side flange 11 to stop the loosening of the right-hand thread, a large one is not required in terms of strength. Although the screw portion 4b is a right-handed screw, if it is a left-handed screw, the screw portion 4b is rotated approximately 90 degrees counterclockwise from the starting point of rotation of the hook portion 3.
If the direction of the angle is θ, the loosening of the left-hand thread can be similarly prevented. Thus, in the case of a right-handed screw, a counterclockwise contact piece is effective in the direction in which the hook is viewed from the shaft, while in the case of a left-handed screw, the contact piece is viewed in the direction of viewing the hook from the shaft. A clockwise contact piece is effective. In the first embodiment shown in FIG. 1, the diameter of the shaft 2 is 12 mm, the length of the hook 3 is 60 mm, and the length of the contact piece 6 is 60 mm.

In FIG. 2, the panel mounting bracket 1 shown in FIG.
Is used as an example, and the panel 9 is attached as a floor slab. Referring to FIGS. 2 and 3A to 3E,
The panel mounting method will be described. As shown in FIG. 3A, a through hole 9a and an accommodation hole 9b larger than the through hole 9a are opened at a predetermined position near the end of the panel 9.
As shown in FIG. 3B, the panel mounting bracket 1 is inserted into the through hole 9a from below, the round washer 7 is disposed from above, and a screw member (nut) 8 is screwed into the screw portion 4b to mount the panel. The metal fitting 1 is temporarily fixed to the panel 9. At this time, the hook 3 of the panel mounting bracket 1 is directed toward the center of the length of the panel 9, but at the same time, the contact piece 6 is directed in the width direction of the panel 9.

Next, as shown in FIG. 3C, the lower surface of the end of the panel 9 is brought into contact with the frame-side flange 11 of the beam 10 made of H-section steel. At this time, since the contact piece 6 faces parallel to the end face 11a of the skeleton side flange 11, the contact piece 6 does not contact the skeleton side flange 11,
There is no problem in contacting the lower surface of the end portion of the panel 9 on the frame side flange 11. However, when the direction θ of the contact piece 6 exceeds 90 degrees counterclockwise with respect to the starting point of the rotation of the hook piece 3 and is up to 160 degrees, there is a possibility that the contact piece 6 comes into contact with the skeleton side flange 11. Get higher. For this reason, the direction of the hook 3 is shifted clockwise as appropriate, and the hook 3 and the contact piece 6 are shifted.
However, both of them need not be in contact with the skeleton side flange 11. Therefore, it is preferable that the angle θ be approximately 90 degrees or less.

Next, as shown in FIG. 3 (D), the panel mounting bracket 1 is rotated by 180 degrees, and the hook 3 is directed toward the frame side flange 11. At this time, while checking the lower part of the panel by hand or visually, the hook part 3 is attached to the frame side flange 1.
1, but if the end portion 4a of the one end 4 of the shaft portion 2 is provided with a display indicating the direction of the hook portion 3 as described above, the hook can be easily locked by confirmation from above. The part 3 can be in the direction of the skeleton side flange 11. At this time, the contact piece 6
Is in a state of being arranged close to the end face 11a of the skeleton side flange 11. Subsequently, in this state, when the upper screw member (nut) 8 is fully tightened and tightened, the contact piece 6 is
a, and at the same time, the hook 3 is
Hanged on. Therefore, in this state, even if the right screw of the screw portion 4b tries to loosen, the contact piece 6 comes into contact with the end face 11a and resists, and the right screw does not loosen.
Does not come off from the skeleton side flange 11, and the panel mounting is completed. Here, FIG. (E) corresponds to X- in FIG.
It is X sectional drawing and has shown the state of the contact piece 6. FIG. In addition,
When the screw member (nut) 8 is fully tightened, it is preferable that the end 4a of the one end 4 of the shaft portion 2 does not protrude from the panel surface, from the standpoint of fitting.

By filling the housing hole 9b with a sealing material or mortar, a screw member (nut) 8 is formed.
Alternatively, when one end 4 of the shaft portion 2 of the panel mounting bracket 1 is fixed to the panel so as not to rotate, a screw member (nut) is formed.
8 is loose or the frictional resistance between the panel 9 and the screw member (nut) 8 is particularly small,
Since the right screw and the screw member (nut) 8 screwed and fastened do not rotate together, the shaft portion 2 rotates, and the locking portion 3 integrated with or restricted from rotating with the shaft portion 2 can also rotate. Therefore, it is possible to completely prevent the flange 11 from coming off the skeleton side flange 11, which is more preferable. Other fixing methods include a method of fixing the screw member (nut) 8 or one end 4 of the shaft portion 2 of the panel mounting bracket 1 to the panel 9 in the accommodation hole 9 by using a metal fitting or a nail. You can do it.

The panel mounting bracket 1 according to the present invention comprises:
It can also be used for panels constituting a wall having a vertical panel surface as shown in FIG. 8 or for attaching panels to a diagonal sloped roof. At that time, the beam 10 made of the H-section steel shown in FIG. 3 is appropriately replaced with a column member. Further, the beams and columns are not necessarily limited to the H-shaped steel, and other members such as an angle and a channel steel may be used as long as the hanging portion 3 can be hung.

FIG. 4 shows a panel mounting bracket 1 according to the present invention.
Now, two other examples having different configurations of the hook portion 3 and the contact piece 6 will be described. In FIG. 4A, the contact piece 6 is made of a rod-shaped steel material, and is integrated with the side of the other end 5 of the shaft 2 by welding. In the figure (B), the contact piece 6 is manufactured by bending a thin plate.
It was formed by being sandwiched between the other end 5 of the shaft 2. Also, as compared with FIG. (A), the upper surface of the contact piece 6, that is,
Two claws 12 are provided on the side of the panel 9, and when the screw member (nut) 8 is screwed and fastened, the claw 12 penetrates into the back surface of the panel 9. Even if the tightening of the shaft portion is loose or the frictional resistance between the panel 9 and the screw member (nut) 8 is particularly small, etc.
However, since it does not rotate together with the screw member (nut) 8, the locking portion 3 which is integrated with the shaft portion 2 or whose rotation is restricted.
Since it does not rotate, it can be completely prevented from coming off from the skeleton side flange 11, which is more preferable.

4 (A) and 4 (B), in both cases, the portion which comes into contact with the skeleton side flange 11 is a flat surface as the hooking portion 3, and even if the panel 9 is in the form of a hook bolt, it is stable. Can be attached.
FIG. 5 shows an example of the panel mounting bracket 1 when a nut is used as the shaft portion 2 and the screw portion 4b is a female screw (right-handed screw). In this case, the screw member 8 is replaced with a nut,
The panel 9 is tightened with bolts from the front side. In this case, even if the indication indicating the direction of the hook 3 is provided at the end 4a of the one end 4 of the shaft 2 as described above, the indication is provided by the bolt, so It is not possible to work only with confirmation. In addition,
The hook portion 3 is provided by welding a steel plate to the other end 5 of the shaft portion 2 by welding. The contact piece 6 was provided by bending a part of a steel plate.

FIG. 6 shows an example of the panel mounting bracket 1 when the direction θ of the contact piece 6 is other than 90 degrees. Here, as in the other embodiments, this is an example of the panel mounting bracket 1 in which the screw portion 4b is formed of a right-hand thread and the direction θ of the contact piece 6 is about 60 degrees. When the position of the shaft portion 2, that is, the position of the through hole 9 a is apart from the end face 11 a of the skeleton side flange 11, if the direction θ is smaller than 90 degrees and the contact pieces 6 are provided, the skeleton side flange 11 This makes it possible to hang the hooking portion 3 vertically vertically on the end face 11a of the base member, which is preferable. As described above, the preferable range of the direction θ of the contact piece 6 depends on the distance between the shaft portion 2 (through hole 9 a) and the end face 11 a of the skeleton side flange 11, the width of the hook portion 3 and the width of the contact piece 6. Depends on
Preferably, the angle is in the range of 45 degrees to 135 degrees, and more preferably, about 90 degrees (about 60 degrees to 120 degrees).

The screw member (nut) 8 has a loosening prevention mechanism such as a disk-shaped spring washer or a serrated one, or a nut and a round washer are integrated by caulking. May be adopted. Each of the first to eighth embodiments shown in the drawings is an example in which the hook portion is integrated with the shaft portion, but the hook portion is formed in a state in which rotation is restricted with respect to the shaft portion. Configuration
The effects are the same.
