Description

[Detailed description of the invention] The present invention relates to a system ceiling hanging device in which a ceiling material is supported by a main T-bar and a cross T-bar, and the main T-bar is attached to a hanger fixed to a hanging bolt. The purpose is to reduce the cost of the hanger, improve workability, and improve earthquake resistance by preventing it from easily twisting against horizontal forces applied to the main T-bar.
The purpose of this is to ensure that the installation can be done reliably, and the third purpose is to make the installation easy without vertical or horizontal deviation.

In general, a system ceiling suspension device supports a ceiling material 3 with a main T-bar 1 and a cross T-bar 2 perpendicular to the main T-bar 1, as shown in Fig. A main T-bar 1 is attached to a hanger 5 provided at the tip of a book hanging bolt 4. Conventionally, in such a system ceiling hanging device, a hanger 5' is formed of a hanging piece 6 and an auxiliary hanging piece 7 as shown in FIG. The hanging piece 6 and the auxiliary hanging piece 7 are sandwiched by a screw 9 and suspended by a hanging bolt 4. Numeral 10 is a nut for fixing the hanger 5' to the suspension bolt 4. In this case, the hanger 5' is made up of two parts, which makes it expensive, and since it is supported at the upper end of the main T-bar 1, it can be twisted by the horizontal force of the ceiling material 3 in the event of an earthquake, etc. However, the ceiling material 3 tends to fall easily, and earthquake resistance is low.

The present invention has been devised in view of this point, and will be described in detail below with reference to Examples.

In FIG. 3, reference numeral 5 denotes a hanger, which is fixed to the hanging bolt 4 with a nut 10. Reference numeral 11 denotes cutting claws, and two of them are provided on the hanger 5 so as to face in opposite directions. Reference numeral 12 denotes a cut-and-raise pawl insertion hole provided in the vertical portion 13 of the main T-bar 1, and a locking hole 14 communicating with the cut-and-raise pawl insertion hole 12 in an L-shape is provided. The width of this locking hole 14 is set to be approximately the same as the plate thickness of the cut and raised claw 11. Cut-and-raise nail 1 of hanger 5
1 and insert it into the nail insertion hole 12, and then insert the fourth
By locking into the locking hole 14 as shown in the figure, the main T-bar 1 can be hung with a single touch from the hanger 5, and a system ceiling can be constructed by simply placing the ceiling material 3 on the main T-bar 1. can.

In FIG. 5, a tongue piece 15 is cut and raised on the vertical part 13, and the hanger 5 is attached in the same manner as in FIG. Cut and raise the tongue piece 15 by bending it to the side to form the nail 1
1 to prevent the hanger 5 from coming off.

In FIG. 6, the hanger 5 is provided with a bent tongue piece 19 that presses the vertical part 13 of the main T-bar 1. The bent tongue piece 19 is attached to the hanger 5 when the cut-and-raised claw 11 is locked in the locking hole 14. Bend it towards the main T-bar 1 side and cut and raise the claw 1
The main T-bar 1 is held between the main T-bar 1 and the bent tongue piece 19. Therefore, the main T-bar 1 will not come off or come off from the hanger 5. 20 is a reinforcing rib provided on the hanger 5, which prevents the hanger 5 from being deformed when a horizontal force is applied. Figure 7 shows the bent tongue piece 19 as the main T.
The bar 1 is bent from above, and in FIG. 8, an inclined surface 21 is provided on the lower surface of the bending tongue piece 19, so that the main T-bar 1 can be held even more firmly.

As mentioned above, the present invention has two cut-and-raised claws facing oppositely to each other on the hanger, and a cut-and-raised claw insertion hole in the vertical part of the main T-bar and an L-shaped hole in the cut-and-raised claw insertion hole. By providing a communicating locking hole, inserting the cut-and-raised claw into the cut-and-raised claw insertion hole, and locking it in the locking hole to attach the main T-bar to the hanger, the cost of the hanger can be reduced. In addition, the main T-bar can be easily attached with one touch, improving workability.
Moreover, it does not easily twist due to the horizontal force applied to the main T-bar, improving earthquake resistance.
Further, since a tongue piece is provided on the vertical part of the main T-bar, and the tongue piece is brought into contact with the cut-and-raised claw when the cut-and-raised claw of the hanger is locked in the locking hole, Since the cut-and-raise claws will not come out of the locking holes, the main T-bar can be reliably attached to the hanger. Since the T-bar is cut and raised and held between the claws and the bent tongues, the main T-bar does not shift vertically or horizontally, and it can be mounted reliably and easily.
