Description

[Detailed description of the invention] The invention relates to the structure of a ceiling, and includes a plurality of anchors 2 protruding downward from the building frame 3 of the ceiling, and an upper place attachment piece that faces diagonally downward at the bottom of the anchors 2. A plurality of pieces 4 are provided radially, hangers 5.5a and 5b are suspended from the lower part of the hanging bolt 1 hanging downward from each anchor 2, and a plurality of lower place attachment pieces 7 facing diagonally upward are attached to the hanger 5. The lower place attachment piece 7 of the hanger 5 is provided radially, and the upper end of the place 8 is fixed to the anchor 2 by screwing to the upper place attachment piece 4, and the hanger 5 is suspended from the hanging bolt 1 vertically installed on another anchor 2. This relates to a ceiling structure in which the lower end of the place 8 is fixed with screws, and the ceiling material 25 is supported by the channel 16 held by the hanger 8.

In recent years, ceilings of buildings have been subjected to periodic external forces due to vibrations such as earthquakes, resulting in accidents such as ceiling materials falling.

This is because there are problems with the support structure of the ceiling, especially around the walls, and oversights in construction at the site.

Therefore, in order to make the ceiling and the building frame as rigid as possible, reinforcement is performed using a place (reinforcing material).

However, in the past, the place 8 was hung diagonally between the hanging bolts 1 and 1 hanging from the anchor 2 protruding from the building frame 3 in the ceiling and fixed by welding, or the hanging bolt 1 and the channel 16 (so-called C channel) were fixed. ), the place 8 was hung diagonally between the two and fixed by welding.

Therefore, welding must be carried out in the ceiling, which is dangerous and can only be carried out by a skilled person.

Moreover, distortion caused by inaccurate welding disrupts the ceiling line.
Furthermore, when subjected to vibrations, the welded parts tend to come off and sometimes fail to function as a place.

The present invention was developed in view of the above points, and it is possible to perform reinforcement with a place easily and safely without the need for welding, even by non-skilled workers, and it is possible to securely fix the place and prevent vibrations. It is an object of the present invention to provide a ceiling structure in which there is no fear that the place will fall off even when the place is moved, and in addition, the place can be attached in various directions.

Embodiments illustrating the present invention will be described in detail below.

3 in the figure is a building frame in the ceiling, and a plurality of anchors 2 whose upper part is spread out in an inverted shape are buried at equal intervals in the building frame 3, and the lower part of the anchor 2 is from the building frame 3. It protrudes downward.

There is a screw hole 9 in the center of the lower part of the anchor 2 as shown in Figure 3.
is drilled and the hanging bolt 1 is installed vertically.

Further, a plurality of upper place attachment pieces 4 radially protrude 7 are provided around the center portion and are oriented diagonally downward, and screw holes 11 are bored in the upper place attachment pieces 4.

On the other hand, a hanger 5 provided with a plurality of lower place attachment pieces 7 is suspended from a hanging bolt 1 which is hung from one anchor 2 and another anchor 2 adjacent to it.

The hanger 5 is provided with a horizontal part 13 at the top thereof, which has a hole 12 for connecting to the hanging bolt 1.
The hanging bolt 1 is fixed on the lower surface of the bolt 3 with a nut or the like.

Lower place attachment pieces 7 are provided radially around this horizontal portion 13 and are inclined downward at a certain angle and face obliquely upward, and an insertion hole 6 is formed in the lower place attachment piece 7. It is.

Further, the lower part of the hanger 5 is formed with a groove part 15 bent into a U shape, and a channel 16 is inserted into this groove part 15 to hold the channel 16 horizontally.

The groove portion 15 is formed by connecting a long vertical piece 17 vertically to the horizontal portion 13 and a short vertical piece 18 facing the long vertical piece 17 with a horizontal piece 19. A bent portion 20 is formed in a dogleg shape, and the upper surface of the channel 16 is pressed down by this bent portion 20.

One end of the threaded place 8 is screwed into the screw hole 11 of the upper place attachment piece 4 of the anchor 2, and the other end is screwed to the upper place attachment piece 4. Hanging bolt 1 hanging from another anchor 2
By inserting the hanger 5 suspended into the insertion hole 6 of the lower place attachment piece 7 and fixing it to the back side of the lower place attachment piece 7 with a nut, it is screwed against the lower place attachment 7, thereby attaching the hanger 5 to the lower place attachment piece 7. Install it diagonally.

The channel 16 is held horizontally by the hanger 5 and other hangers 5a, 5b without lower place attachments 7.

T-bars 21 are fixed at equal pitches to the lower part of the channel 16 by clips 22, and T-bars 21 are fixed to the wall 23 at equal pitches.
An L bar 24 is fixed at the same height as the bar 21.

Ceiling material 25 consists of 21 T-bars, 21 T-bars and 2 L-bars.
It is being placed between 4 and 4.

5 and 6 show another embodiment of the present invention, in which a hanging bolt 1 is inserted into a hole 30 of a place support plate 26 formed by bending a flat plate, and a nut 27 is attached to the lower end of an anchor 2. The upper place attachment piece 4 is bent upward at a certain angle and is bent on the place support plate 26 so as to face obliquely downward, and the upper place attachment piece 4 has an insertion hole 28. It is perforated.

In this case, the place 8 is screwed to the upper place attachment piece 4 by inserting the upper end of the place 8 into the insertion hole 28 and tightening nuts 29 from both sides of the upper place attachment piece 4.

In the present invention, as described above, the anchor is provided with an upper place attachment piece that faces diagonally downward, and the hanger is provided with a lower place attachment piece that faces diagonally upward. Since the place attachment piece and the lower place attachment piece are fixed with screws, the place can be attached with screws and there is no need for welding, making it easy and safe even for non-experts. The place can be installed by work, and since the place is screwed, the place can be installed reliably without fear of the place falling off due to vibration or the like.

Further, since a plurality of upper place attachment pieces and lower place attachment pieces are provided radially, the place can be attached in various directions.
