Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel mounting bracket 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 1 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 the 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 the column (or 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 a hand or a tool. However, the locking portion 58 is fixed not in a right angle but in an inclined state with respect to the end surface 57 a of the flange 57. In many cases, there was a problem in appearance. 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. Further, a general round washer 52 cannot be used as a 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 be loosened. Further, in the second conventional example, the nut 5
It is necessary to stop the rotation of the co-rotating washer 63 with the stop pin 64 or the stop piece 65 when fastening by turning the 4. 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 stopper pin 64, and the deformation of the building and the various vibrations after the panel mounting is completed. For example, when the nut 54 is loosely rotated, the fixing of the co-rotating washer 63 to the panel may be disturbed depending on the dimensions of the stopper 65 such as the height and position.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a panel mounting bracket which does not rotate even if it is not fixed by welding and does not come off the building frame side.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided at least one end of a shaft having a screw formed at one end thereof, with a locking portion integrated with the shaft or a locking portion whose rotation is restricted. A panel mounting bracket characterized in that a claw portion penetrating into the panel is formed in the vicinity of the shaft portion of the engaging portion so as to protrude toward the shaft portion side. Since the panel mounting bracket of the present invention is configured as described above, the claw formed near the shaft of the hooking portion projects toward the shaft when the panel is mounted and the screw on one end of the shaft is tightened. By automatically penetrating the panel, the rotation of the shaft can be prevented, so that the rotation of the locking portion that is integral with or restricted from rotating can also be prevented. This eliminates the need for welding work to the building skeleton side of the part, thereby simplifying the construction time.

Further, unlike the conventional example 2, the general round washer 5 can be used without preparing the special co-rotating washer 63 in advance.
2 can be mounted on the panel. In addition, there is no processing time required to previously form the eccentric plane 59 on the male screw 53, and therefore, the amount of screw is not reduced by cutting. Therefore, the frictional resistance between the threads at the time of tightening the screw is as high as the conventional example. As a result, the rotation of the nut 54 does not easily become loose 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 will be described later with reference to (D), the beam 10 is rotated by 180 degrees in the state of being close to the flange 11 of the beam 10 when attached to the panel 9. In order not to hinder rotation, it is preferable that the vicinity 5 of the shaft portion of the hook portion 3 is formed compactly in a range close to the shaft portion 2. In the first embodiment shown in FIG.
And the distance from the shaft portion 2 to the claw 6 is 10 mm.
And Also, the edge near the shaft portion 5 of the hook portion 3 was rounded so as to be easily rotated.

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 the nut 8 is screwed into the screw portion 4b to connect the panel mounting bracket 1 to the panel. Temporarily fix to 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.

Next, as shown in FIG. 3C, the lower surface of the end of the panel 9 is brought into contact with the flange 11 of the beam 10 made of H-section steel. Next, as shown in FIG. 3 (D), the panel mounting bracket 1 is rotated by 180 degrees, and
In the direction of. At this time, while checking the lower part of the panel by hand or visually, the hooking part 3 may be directed toward the flange 11, but as will be described later (FIG. 7), the end face 4 a of the one end side 4 of the shaft part 2. Is provided with a display indicating the direction of the hook 3, the hook 3 can be easily attached to the flange 11 by confirmation from above.
Direction.

Up to this point, the claws 6 formed so as to protrude in the vicinity of the shaft portion 5 of the engaging portion 3 of the panel mounting bracket 1 do not penetrate the panel. Subsequently, when the upper nut 8 is fully tightened in this state, the hook 3 is hooked on the flange 11, and at the same time, the claw 6 penetrates the panel 9 from below, and the panel mounting bracket 1 is restrained from rotating. Therefore, in this state, the mounting of the panel is completed without the hook 3 coming off the flange 11. Here, FIG. (E) is a cross-sectional view taken along the line YY of FIG.
Shows a state in which it has penetrated. In addition, when the nut 8 is fully tightened, it is preferable in terms of fitting that the end face 4a of the one end 4 of the shaft portion 2 has a depth dimension 12 so as not to protrude from the panel surface.

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.

Note that the present invention can be applied to various panels as long as the panel can penetrate the nail 6. In particular, lightweight cellular concrete (ALC) has such a softness that the nail 6 can be easily penetrated into the panel. On the other hand, if there is a certain amount of penetration, the ALC around the nail 6 is not affected by ordinary vibration.
Is damaged and the panel mounting bracket 1 has such a strength that the panel mounting bracket 1 does not rotate. FIG. 4 shows other three examples of the panel mounting bracket 1 according to the present invention, which are different in the configuration of the claws 6 and the like.

In FIG. 4A, the claw 6 is formed by sandwiching a bent portion 15 of a thin plate in the vicinity of the shaft portion 5 of the hook portion 3. The number of claws 6 can be changed as appropriate,
There may be three or four or more locations. Note that the hooking portion 3 is formed of a flat plate without providing a step as in the first embodiment. Also in FIG. (B), the claw 6 is a thin plate bent portion 15.
In the vicinity 5 of the shaft portion of the hook 3. The claw 6 is provided at a position closer to the shaft portion 2 as compared with FIG. The hook 3 is provided with a step in the opposite direction in two stages. When the hook 3 is hooked on a beam flange or the like, the hook 3 is elastically pressed more strongly against the beam flange or the like. It is composed.

In FIG. 1C, the hook 3 has a configuration in which the shaft 2 is bent and extended, and the main body of the panel mounting bracket 1 is formed of a hook-shaped bolt. A thin plate bent part 15 formed with claws 6 was inserted into the main body from the side of the hook part 3 and fixed. The lower end surface 16 of the bent portion 15 made of a thin plate has an angle, and once inserted, does not catch on the hook shape and does not return. As shown in FIGS. (A) to (C), the claw 6 can be formed in the vicinity 5 of the shaft portion of the hook 3 without using plastic working or welding. According to this method, rather than by welding
The nail 6 can be formed relatively easily, which is preferable. In particular, in the case of the fourth embodiment (FIG. (C)), it is also possible to configure the panel mounting fitting 1 by attaching the thin plate bent portion 15 to a hook bolt which is a general-purpose member at a construction site. .

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. In this case, instead of the nut 8, a panel 9
It will be tightened with bolts from the front side of the. In this case, even if an indication indicating the direction of the hook portion 3 is provided on the end surface 4a of the one end side 4 of the shaft portion 2 as will be described later (FIG. 7), the display is blocked by the bolt. It is not possible to work only with confirmation from the front side.

FIG. 6 shows an example of the panel mounting bracket 1 which is installed in a state in which the locking portion 3 is not integrated with the shaft portion 2 and its rotation is restricted. Here, a bolt under a square neck is used as the shaft portion 2, and a long hole 14 is provided near the shaft portion 5 of the hook portion 3, and the square root portion 13 fits into the long hole 14. This restricts the rotation of the hook 3. Instead of this, another rotation restricting mechanism may be used. Regarding the depth of the housing hole 9b, in the conventional example 1, the depth is usually set to about 30 mm. However, in the case of the panel mounting bracket 1, the tightening distance of the shaft portion 2 by screwing is increased. In order for the nail 6 to penetrate the panel 9 sufficiently, 35
It is more preferably set to be at least 40 mm, typically about 40 mm. Of course, the 30 mm
However, it is sufficiently applicable.

A preferred height dimension at which the claw 6 is formed to project in the direction of the shaft portion 2 varies depending on the thickness of the panel 9, the depth of the receiving hole 9b, and the thickness of the round washer 7 and the nut 8. Further, it depends on whether the vicinity 5 of the shaft portion of the hook portion 3 is in close contact with the back surface of the panel 9 when the nut 8 is tightened, or is formed with a gap. Therefore, it may be determined appropriately in consideration of these. The nut 8 is provided with a loosening prevention mechanism, such as one with a disc-shaped spring washer, one with a serration process, or one in which a nut and a round washer are integrated by caulking. Is also good.

Further, as shown in FIG. 4C, when the portion where the hook 3 contacts the flange 11 is a flat surface, the panel 9 can be stably mounted even in the shape of a hook bolt. I can do it. On the other hand, the engaging portion 3 as shown in FIGS.
The panel 9 can be mounted in a more stable state if the panel 9 is brought into contact with a wider plane. However,
Integrating or restraining the locking portion 3 on the plate with the shaft portion 2 is troublesome in manufacturing the panel mounting bracket 1, and as in the fourth embodiment (FIG. 4C). The hook bolt type is more preferable.

In the first to sixth embodiments described above, the tip of the claw 6 is pointed, and the claw 6 easily penetrates into the panel 9 when the nut 8 is tightened. However, even if the projection 6 has a rounded tip, the projection 6 penetrates into the panel 9 when the nut 8 is tightened. In this case, in other words, the projection 6 is inserted into the panel 9. , As long as it can restrict the rotation of the panel mounting bracket 1 with respect to the panel 9. Of course, nail 6
The one having a sharp tip is preferable because the nail 6 easily penetrates into the panel 9.

If the indication indicating the direction of the hook is formed on one end of the shaft, the direction of the hook is checked when the screw of the shaft is fastened, and the state of the back of the panel can be checked without checking the state of the back of the panel. It is more preferable that the hook can be securely hooked to the pillar or the flange of the beam on the building frame side only by checking from the front side. FIGS. 7A to 7C show examples of display indicating the direction of the hook 2. (A) is a diagram in which a dot-shaped mark 4c is formed on an end surface 4a on one end side 4 of the shaft portion 2;
(B) shows a bent line marking 4c indicating the direction on the end face 4a of the one end 4 of the shaft 2, and (C) shows a slight cut surface on the thread 4 b of the one end 3 of the shaft 2. 4d. Instead of this, any display may be used as long as the display allows the direction of the hooking portion 4 to be confirmed.

[0024]

As described above, the present invention has the above-described structure and operation. Therefore, when the screw is tightened at one end side of the shaft portion when the panel is mounted, the claw protrudes toward the shaft portion near the shaft portion of the hooking portion. The part penetrates the panel to prevent the rotation of the shaft part, thus preventing the rotation of the hanging part, eliminating welding work on the building part side of the hanging part, and simplifying construction work Become. In addition, the panel can be mounted using a general-purpose round washer without the need to prepare special co-rotating washers in advance, and since there is no thread cutting, the panel mounting is completed. The nuts are less likely to loosen due to deformation of the building or various vibrations.

Furthermore, no special work such as stopping with a set pin is required, and the claw portion can be automatically penetrated into the panel at the time of mounting the panel and tightening the screw at one end of the shaft portion. In addition, if the indication indicating the direction of the hook is formed at one end of the shaft, when fastening the screw of the shaft, the direction of the hook is checked, and the state of the back of the panel is not checked from the panel front side. Only by confirming the above, the hanging portion can be securely hooked to the column or the beam flange on the building frame side.
