BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling hanging metal fitting for a steel ceiling frame.

[0002]

2. Description of the Related Art In general, a ceiling is connected by a hanging tree between a hanging tree support passed between beams and a field edge to which a ceiling panel is attached, and a peripheral edge of the ceiling panel is provided by a peripheral edge provided on a partition panel. Is fixed. In the case of such a ceiling structure, a hanging tree receiver is provided for each room partitioned by the partition panel,
The construction of the ceiling board, the ridge, the hanging tree, and the surroundings has to be performed, so that not only a lot of work time is required but also the cost is increased.

[0003] For this reason, the wooden beam is framed into a rectangular frame to form a panel, and the ceiling panels are connected to construct a ceiling.
It has been proposed to partition with a partition panel.
A ceiling hanging bracket for hanging and fixing such a ceiling panel to a beam is known (see Japanese Patent Application Laid-Open No. Hei 6-193188 filed by the applicant).

[0004]

However, when constructing a ceiling using this ceiling suspension fitting, the ceiling is constructed so that the beam is fixed parallel to the floor and a horizontal surface parallel to this beam is formed. In general, there are cases in which, on the top floor or the like, a horizontal ceiling is formed for a beam that is inclined at a constant gradient, or a ceiling that is inclined with respect to the floor is formed for a horizontal beam. When forming a ceiling with a slope that is relatively different from the slope of such a beam, using the above-mentioned ceiling suspension fittings requires adjusting the slope within the length range of the connecting bolts, which limits the slope that can be set. In addition, since the connecting bolt is always orthogonal to the beam engaging plate, there is a problem that the work is difficult to perform.

Further, in order to adjust the height position of the ceiling panel with respect to the beam, it is necessary to insert a hexagon wrench through the notch formed in the panel engaging plate and rotate the connecting bolt at a position directly below the beam. It is difficult to work, and every time one ceiling panel is installed, the panel engaging plate of the ceiling hanging metal fixture and the wood crosspiece on one side of the ceiling panel must be nailed and fixed, which makes the work complicated. There was also a problem.

For the purpose of making the ceiling incombustible and improving the strength of the ceiling groundwork, the applicant of the present invention has filed Japanese Patent Application Laid-Open No.
As described in Japanese Patent Publication, a steel ceiling frame formed by frame-forming a steel material is proposed, but this steel ceiling frame is formed by framing the above-mentioned wooden cross member in a rectangular shape. Even when it is used in place of the ceiling frame, it is not possible to form the ceiling with a gradient relatively different from the gradient of the beams.

The present invention has been made in view of the above problems, and provides a ceiling hanging metal fitting capable of easily mounting a steel ceiling frame at a gradient different from that of a beam to adjust the height. It is a thing.

[0008]

In order to achieve the above-mentioned object, according to the present invention, a notch opening which can be inserted into a flange of a beam is formed, and a wing bolt located above the notch opening is provided. The hanging metal fittings that are screwed together, the field edge metal fittings that can be fitted around the field edges of the steel ceiling frame, and the threaded metal fittings that are screwed in the vicinity of the edge facing the cutout opening of the hanging metal fittings, and the steel ceiling frame It consists of a connecting bolt that is inserted into the field edge fitting at a position away from the field edge, and the connecting bolt is
It is rotatable about the horizontal axis with respect to the hanging metal fittings, and while attaching the hanging metal fittings to the flanges of the beams, the field edge metal fittings are mounted inside the steel ceiling frame via a pair of nuts screwed to the connecting bolts. It is characterized by being held from above and below.

The connecting metal fitting 23 has an L-shaped cross section, and the bottom edge of the notch opening 21a of the hanging metal fitting body 21 is formed in a saw blade shape. Further, the horizontal piece 232 of the connecting fitting 23 is formed with a female screw 23a into which the connecting bolt 4 can be screwed.

The field metal fitting 3 is a field metal fitting body 31 bent in a substantially b-shape so as to surround the outer peripheral surface of the field frame 14 forming the framework of the steel ceiling frame 11, and this field metal fitting. The vertical piece 321 is integrally welded to the inner vertical piece 311 of the main body 31 by spot welding, and is composed of a mounting bracket 32 having an L-shaped cross section. The field metal fitting main body 31 is a thin plate, and the mounting bracket 32 is thicker than that. Each is formed of a plate. Then, the extension of the upper horizontal piece 312 of the field edge fitting body 31 and the horizontal piece 322 of the mounting fitting 32 are formed with holes through which the connecting bolts 4 can be inserted, respectively. So that the upper horizontal piece 312 of the field edge fitting main body 31 and the horizontal piece 322 of the mounting fitting 32 can be sandwiched from above and below via the pair of nuts 5 screwed into the connecting bolts 4 when inserted. It has become. In this case, the connecting bolts 4 are separated from the edge of the flange h of the beam H and the edge 14 that forms the framework of the steel ceiling frame 11.
It is designed to be placed between positions away from.

By the way, as shown in FIG. 3, the steel ceiling frame 11 mounted by the ceiling hanging metal fitting 1 has two runners 12, each of which is formed by roll-forming a galvanized steel sheet into a U-shaped cross section, and a cross section. It is formed by combining one runner field edge 13 bent in a substantially C-shape and a plurality of field edges 14 bent in a substantially rectangular cross section.
Specifically, the two runners 12, 12 are arranged so that the grooves thereof face each other, and the runner field edge 13 is arranged at one end of these runners 12 so that the grooves thereof face inward. A rectangular frame is formed by screwing the field edge 14 from the lower side to the other end of the runner 12 to form a rectangular frame, and one or more are provided between the runner field edge 13 and the field edge 14 that form this frame. The book frame 14 is temporarily fixed to the runner 12 with an adhesive tape or the like. The field edge 14 fitted into the runner 12 is slidable along the groove of the runner 12 by removing the adhesive tape, and the runner field edge 13 and the field that form the framework of the steel ceiling frame 11 The rim 14 can be released from the fixing to the runner 12 by removing the screw, and the fixing position with the runner 12 can be adjusted, or the end edge of the runner 12 can be cut off, and then the rim 14 can be fixed between the other ends again. It can be screwed. Also, runner field 13
On the side surface of the field and the side surface of the field edge 14 (see FIG. 2)
Are formed to improve the bending strength.

The steel ceiling frame 11 has standardized vertical and horizontal dimensions so that it can be matched to the size of the ceiling. For example, 1 m × 1 tatami mat, which is approximately equivalent to 1 tatami mat.
Plural kinds of sizes are prepared based on 2 m.

The steel ceiling frame 11 thus constructed
In order to horizontally attach the beam to the beam H that is inclined at a constant gradient using the ceiling hanging metal fitting 1, first, according to the mounting height of the steel ceiling frame 11 to the beam H, that is,
The saw-toothed bottom edge of the notch opening 21a of the hanging fitting body 21 and the upper nut 5 so that the inclination is set with respect to the beam H.
Adjust the interval between and in advance. After this, the ceiling hanging metal fitting 1
The upper horizontal piece 312 of the field edge metal fitting body 31 is pushed open, and as shown by the chain line in FIG. 3, the field edge 14 forming the framework of the steel ceiling frame 11 is fitted from the outside in the vicinity of the runner 12. Then, connect the connecting bolt 4 to the field edge fitting body 3
1 and through the holes formed in the mounting bracket 32,
The nut 5 is screwed into the connecting bolt 4 and the field edge fitting 3 is attached.

Next, after a temporary fixing jig (not shown) is attached to the flange h of the beam H, one runner 12 of the steel ceiling frame 11 is inserted into the temporary fixing jig and temporarily held, and the steel ceiling frame 11 is then held. Lift up around the temporary fixing jig. Then, after the other runner 12 and the runner field edge 13 that form the framework of the steel ceiling frame 11 are run along the marking lines that have been marked on the wall surface of the inner wall frame in advance, respectively, the other runner 12 and the runner field are formed. The edge 13 is screwed through the groove to the wall corner of the inner wall frame. The other runner 1 of the steel ceiling frame 11
2 and the runner field edge 13 are screwed, the notch opening 21a of the hanging fitting body 21 of the hanging fitting 2 is completed.
After being inserted into the flange h of the beam H, the butterfly bolt 22 is tightened to fix the ceiling suspension fitting 1 to the beam H.

As a result, the three sides forming the frame of the steel ceiling frame 11 can be supported with respect to the inclined beam H so that the steel ceiling frame 11 is horizontal. That is, the other runner 12 and runner field edge 13 that form the framework of the steel ceiling frame 11 are screwed to the wall surface of the inner wall frame, and the field edge 14 that forms the framework is attached to the beam H via the ceiling hanging metal fitting 1. It can be hung. In this case, since the connecting fitting 23 of the hanging fitting 2 is rotated around the horizontal axis via the rivet R, the connecting bolt 4 can be hung vertically. After that, if the temporary fixing jig is removed, the mounting of the steel ceiling frame 11 is completed.

To attach the second steel ceiling frame 11, a temporary fixing jig is similarly attached to the flange h of the beam H, and then the steel ceiling frame 11 is attached to this temporary fixing jig.
One runner 12 is inserted and temporarily held. Next, the steel ceiling frame 11 is lifted upward with a temporary fixing jig as a center, and the marking line attached to the wall surface of the inner wall frame and the field edge 14 forming the frame of the first steel ceiling frame 11 are formed.
After running the other runner 12 and the runner field edge 13 that form the framework of the second steel ceiling frame 11, the other runner 12 on the wall surface of the inner wall frame, and one runner field edge 13 The field edges 14 forming the framework of the steel ceiling frame 11 are screwed through the grooves. Then, the hanging fitting body 2 in the hanging fitting 2
After inserting the notch opening 21a of No. 1 into the flange h of the beam H, the butterfly bolt 22 is tightened to fix the ceiling hanging metal fitting 1 to the beam H. As a result, the other runner 12 forming the framework of the second steel ceiling frame 11 is screwed to the wall surface of the inner wall frame, and the runner edge 13 forms the framework of the first steel ceiling frame 11. A screw is applied to the hanging edge 14, and the hanging edge 14 is hung on the beam H via the ceiling hanging metal fitting 1. After this, if you remove the temporary fixing jig,
The installation of the second steel ceiling frame 11 is completed.

Similarly, with respect to the third and subsequent steel ceiling frames 11, the other runner 12 and runner field edge 13 forming the framework of the third and subsequent steel ceiling frames 11 and the marking line attached to the wall surface of the inner wall frame and the preceding stage, respectively. A screw is applied according to the field edge 14 that forms the framework of the steel ceiling frame 11, and the field edge 14
Is hung on the beam H via the ceiling hanging metal fitting 1. And
When reaching the wall surface corner of the other inner wall frame, the field edge 14 of the steel ceiling frame 11 may be screwed to the wall surface of the inner wall frame.

At this time, if a mounting error occurs,
After loosening the screws to release the fixation between the runner 12 and the field rim 14, the field rim 14 is moved so as to be in close contact with the wall surface of the inner wall frame with respect to the runner 12, and a screw is struck, and the screw is again attached to the runner You can drive it in between and fix it.

Similarly, the second row of steel ceiling frames 11 are fixed with screws. When constructing the steel ceiling frame 11 of the second row, the other runner 12 forming the framework thereof is the one runner 1 forming the framework of the steel ceiling frame 11 of the first row that was constructed earlier.
It is something that is screwed to 2.

After the ceiling is constructed in this way, the partition panel is arranged. Therefore, when the ceiling height from the floor is adjusted, the groove formed at the lower end of the connecting bolt 4 is adjusted to the set dimension. By inserting a screwdriver into and rotating the connecting bolt 4 with respect to the hanging metal fitting 2 attached to the beam H, the lower nut 5 may be positioned. Next, by tightening the upper nut 5 and sandwiching the field edge fitting 3 with the pair of nuts 5, and holding it,
Can be fixed to the adjusted ceiling height.

As described above, the runner 12 and the runner field 13 forming the framework of the steel ceiling frame 11 are sequentially fixed to the inner wall frame or the adjacent steel ceiling frame 11, and the framework of the steel ceiling frame 11 is formed. Since the ceiling can be formed by suspending the hanging edge 14 on the beam H with the ceiling hanging metal fitting 1, labor can be saved. And because the partition panel is installed,
In order to adjust the height position of the steel ceiling frame 11 with respect to the beam H, in the inside of the steel ceiling frame 11, the field edge 1
After rotating the connecting bolt 4 using the space formed between the four, the nut 5 may be tightened, and the work can be performed in a comfortable posture. In addition, the ceiling hanging metal fitting 1 can be attached by fitting the field edge fitting 3 into the steel ceiling frame 11 in advance and screwing the nut 5 into the connecting bolt 4 inserted into the field edge fitting 3, so that nailing work can be performed. Is unnecessary and the work can be simplified.

Further, the connecting bolt 4 of the ceiling suspension fitting 1
Since the connecting fitting 23 is rotatably connected to the hanging fitting main body 21 via the rivet R about the horizontal axis, the connecting fitting 23 can be oriented in the vertical direction regardless of the gradient of the beam H, and the work is easy. In addition, the steel ceiling frame 11 can be attached to the beam H with a relatively large gradient.

In the above-described embodiment, the case where the steel ceiling frame 11 is horizontally attached to the beam H inclined at a constant gradient has been described.
Can be oriented in an arbitrary angle direction around the horizontal axis with respect to the hanging metal fitting main body 2, so that the steel ceiling frame 11 can be attached to the horizontal beam H at a constant gradient. Moreover, it is possible to deal with the case where the gradient of the beam H and the gradient of the steel ceiling frame 11 are different.
