Description

[Detailed description of the invention] This invention is a field edge holding metal fitting, especially a field edge holding metal fitting.
This invention relates to a field edge holding metal fitting made up of two holding pieces.

Conventionally, a ceiling mounting structure has a configuration as shown in Figure 1, in which 1 is a ceiling slab 2.
This is a bolt buried in the side, and the hanger 3 is fixed to this bolt 1 using a nut (not shown).
A U-shaped holding portion 4 at the lower part of the hanger 3 holds a field edge receiver 5, and a field edge 6 is attached perpendicularly to the field edge support 5 using a field edge holding metal fitting 7. I have to. The field edge receiver 5 has a substantially U-shaped cross section, and the field edge 6 is formed so that its upper side is open and an inwardly bent piece 9 is provided on the upper side of the side walls 8, 8. The folding pieces 9, 9 are held by locking pieces 10, 10 provided on both sides of the lower part of the edge retaining fitting 7, thereby attaching the frame. The field edge holding fittings 7 are made of a strip-like material extending in the vertical direction, and are fixed to the field edge receiver 5 at points corresponding to both sides 12, 12 of the horizontal piece 11 provided on the upper side of the field edge receiver 5. It is fixed by bending inward using the fulcrum. In addition,
Holes 4a, 4a are formed in the retaining portion, and upward movement of the field edge support 5 is regulated by bolts and nuts that penetrate these holes 4a, 4a.

However, according to the above-mentioned conventional field edge holding metal fittings, since the structure is fixed to the field edge support 5 by simply bending a part thereof, for example, the field edge 6
When large wind pressure is applied to the ceiling held by the ceiling, the bending piece 9 will step over the locking piece 10 due to the vertical vibration of the roof edge 6, causing the locking piece to It had the disadvantage that it fell off from 10.

Therefore, the purpose of this invention is to
Alternatively, the above-mentioned drawbacks are eliminated by preventing the field edge from easily falling off from the field edge holding fitting even when vibrations are applied in the left-right direction, and will be described in detail below using examples.

FIGS. 2 and 3 are simplified configuration diagrams showing one embodiment of the field edge holding metal fitting according to the present invention, and the same parts as in FIG. 1 are denoted by the same reference numerals. In each figure, the field edge holding fitting 20 consists of two holding pieces 21 and 22, and both the holding pieces 21 and 22 correspond to the left and right sides of the field edge support 5 and are vertical pieces 2 parallel to each other.
3, 23, and mounting pieces 24, 2 bent so as to extend in the horizontal direction on the upper side of the vertical pieces 23, 23.
5, and locking pieces 26, 26 provided on the left and right sides of the lower side of the holding pieces 21, 22, and the vertical piece 23 of the holding piece 22 is connected to the vertical piece 23 of the other holding piece 21. The length of the mounting piece 25 is set to be slightly shorter than that of the mounting piece 2.
The length of one mounting piece 24 is set to be longer than the width of the field edge receiver 5, and is mounted on the upper surface side of the horizontal piece 11 on the upper side of the field edge receiver 5. A bolt 28 penetrates downward through a hole 27 provided at the tip of the mounting piece 24 that protrudes from one side of the field edge holder 5.
This bolt 28 is screwed into a tap hole 29 provided in the mounting piece 25 to hold the mounting piece 25.
Further, the locking pieces 26, 26 can enter the gap 30 formed by the inwardly bent bent pieces 9, 9 provided on the field edge 6, and can hold the field edge 6.

To attach the field edge 6 to the field edge receiver 5 side, first hold the field edge 6 by the holding piece 21 by locking the locking piece 26 side of the holding piece 21 to the gap 30 side, and then After locking the locking piece 26 side of the holding piece 22 on the gap 30 side and positioning both the vertical pieces 23, 23 so as to face both left and right side surfaces of the field edge receiver 5, the bolt 28 is inserted into the hole 2.
7 and screw this bolt 28 into the tapped hole 29, or replace the tapped hole 29 with the bolt 28.
The mounting piece 25 is formed as a through hole through which the mounting piece 25 is inserted, and is mounted by tightening a nut onto the bolt 28 and fixing the mounting piece 25 to the bolt 28. Note that the mounting piece 25 is positioned so as to protrude in the same direction as the direction in which the mounting piece 24 projects. Therefore, according to the present invention,
Since the holding piece 22 can be pulled upward by tightening the bolt 28 or the above-mentioned nut, the field edge 6 held by this holding piece 22 is also pulled upward, and this field Since the bent piece 9 side of the edge 6 is in pressure contact with the lower surface 5a side of the field edge receiver 5, even if a vertical force is applied to the field edge 6, the field edge 6 will not touch the lower surface 5a of the field edge receiver 5. It is possible to solve the problem that the bent piece 9 does not move in the vertical direction due to contact with the locking piece 26, and therefore the bent piece 9 steps over the locking piece 26.
23 are located so as to face both the left and right sides of the field edge receiver 5, the field edge receiver 5 is sandwiched between them, and therefore, large wind pressure is applied to the ceiling from above and below, or an earthquake occurs. However, the field edge 6 does not easily fall off from the field edge holding fitting 20, and therefore reliability can be improved.

In the present invention, an inwardly bent bent piece 9 is provided on the field edge 6, and locking pieces 26 are provided on both sides of the lower part of the holding pieces 21 and 22, and the locking pieces 26 allow the field edge 6 to be fixed.
Although the present invention is not limited to this, the present invention is not limited to this. An outwardly curved bent piece is provided on the edge 6, and a locking piece for holding this bent piece is provided on the lower side of the holding pieces 21 and 22. It may be configured in this manner.

As explained above, the field edge holding bracket according to the present invention includes a vertical piece having a locking piece on the lower side for holding the field edge, and a mounting piece provided on the upper side of the vertical piece so as to project horizontally. The first holding piece is placed on the upper surface side of the field edge holder, a bolt is inserted into a hole formed in a part of this mounting piece, and a second holding piece is inserted into the bolt. The mounting piece of the holding piece can be attached to the holding piece, which allows the field edge to be held securely and with great mechanical strength, and also eliminates the trouble of bending a part of the field edge holding bracket as in the past. Assembly is completed by simply attaching the holding piece to the bolt without requiring much effort, and the installation work is simple, reducing the burden on the operator.
