2. Description of the Related Art Conventionally, when installing ducts, piping, equipment, air conditioners, etc. in a building such as a building, a double beam called a double angle or a double channel is provided near the ceiling of the building in advance. A method of suspending and installing this double beam using a suspending metal is generally adopted.

As the conventional double beam, one using equilateral angle type steel (angle) as shown in FIGS . 1 to 3 , one using C type steel (channel) and one using a belt-shaped member are also used.
No. 57-34320 (Actual Application 58-371).
No. 82) " . In either case, the model steels a to be beams are back-to-back, and a gap c for inserting the hanging metal fitting b is provided between these model steels a. As a method of forming the gap c, as shown in FIG. In addition, a method of welding spacers d made of round bars at regular intervals between the shape steels a,
As shown in FIG. 2, a collar e is interposed between each shape steel a, a bottle f is inserted through each shape steel a and this collar e, and a nut g is tightened to fix the nuts from below. The method is adopted. Furthermore, as shown in FIG.

However, all of these methods require processing in a factory or the like in advance, which is time-consuming and requires storage in multiple sizes depending on the suspension load. There are problems such as difficult management. Further, when the length required for cutting is cut on site, the remaining portion cannot be used for other purposes, and there is a problem that the material is wasted. Furthermore, the figure

It is a defect. The present invention has been made in order to improve the conventional problems, and an object of the present invention is to provide a double-beam supporting metal fitting capable of forming a double beam without the need for machining a shape steel. is there.

[0005]

In order to achieve the above-mentioned object, the present invention fits the upper parts of the double beams on the upper parts of the double beams made of shaped steels arranged side by side with a constant gap. An upper fitting having a notch and a tongue piece fitted between the double beams is fitted between the double beam and the engaging portion where the lower part of the double beam is fitted, and the double beam. A lower metal fitting having a tongue piece is provided, and the space between the upper metal fitting and the lower metal fitting is 2
It is fastened with a fastener inserted between the heavy beams.

[0006]

With the above structure, a double beam for installing tact, piping, air-conditioning equipment, etc. can be easily made on site by using a shape steel that has not been processed in advance.

The upper ends of a pair of beams 4 back to back have a constant gap 5
A notch 2d is formed in which each of the notches 2d is inserted.
The tip of the tongue piece 2e located between d is arcuate so that the upper end of the beam 4 can be easily inserted into each notch 2d.

The other side plate 2b of the upper metal fitting 2 has a narrow width in the vertical direction, and a tongue piece 2f of the same shape is projected at the same position as the tongue piece 2e of the side plate 2a. The top plate 2c is a side plate 2 that is slightly shorter than the side plate 2a.
It is formed to have the same length as b, and has a small hole 2g for inserting the fixing tool 6 such as a bottle at the center.

On the other hand, the lower metal fitting 3 of the support metal fitting body 1 is formed in a substantially U-shaped cross section with the opening facing upward, and the upper metal fitting 2 has side plates 3a, 3b and a lower surface plate 3c which are longer than the side plates 2a, 2b. Have One of the side plates 3a is formed to be longer than the width of the lower portion of the double beam 4 held at regular intervals, and the lower end of the double beam 4 is fitted into both ends from above as shown in FIG. -Like locking parts 3d are formed, and back-to-back 2 is provided at the center between the locking parts 3d.
A tongue portion 3e, which is fitted between the double beams 4 from below and holds the double beams 4 at a constant interval, is provided so as to project upward. Similar to the tongue pieces 2e and 2f, the tip is formed in an arc shape.

The other side plate 3b of the lower metal fitting 3 is formed to have substantially the same length as the side plate 2a of the upper metal fitting 2, and a tongue piece 3f of the same shape is provided to project upward at the same position as the side metal plate 3a. In addition, the bottom plate 3c is a long side plate 3a.
And the side plate 3b having a short length are connected to each other, and thus have a substantially trapezoidal shape, and the screw hole 3 for screwing the fastener 6 into the central portion is formed.
g is drilled.

Next, the operation will be described with reference to FIGS . 7 and 8 . FIG. 7 shows the case where the duct 8 is hung and installed using the hanging metal fitting 7, and FIG. 8 shows the case where the air conditioner 9 is hung and installed. First of all, the angle is cut according to the interval (span) of the steel beam 10 of the building to form the double beam 4, and the upper metal fitting 2 is formed on the upper part of these beams 4 and the lower metal fitting 3 is formed on the lower part in the longitudinal direction. Install at appropriate intervals.

As shown in FIGS. 4 to 6 , the upper metal fitting 2 is mounted such that the upper part of the double beam 4 is attached to each piece 2d of the side plate 2a and the tongue pieces 2e and 2b of the side plates 2a and 2b.
Is inserted between the beams 4 from above.

Further, a double beam 4 is provided on the upper surface of the side plate 3a of the lower metal fitting 3.
The lower part of the double beam 4 is inserted from above so that the lower side follows, and the lower end of the double beam 4 is engaged with the locking part 3d as shown in FIG. The portions 3e and 3f are inserted from below between the beams 4 from below. Then, in this state, the fastener 6 fitted with the washer 6a is attached to the small hole 2g of the upper fitting 2.
Insert it between each beam 4 and insert the tip into the screw hole 3 of the lower metal fitting 3.
It is screwed into g and the fixing tool 6 is tightened. 2 as above
After mounting the required number of the support metal fitting bodies 1 in the longitudinal direction of the heavy beam 4, both ends of the double beam 4 are fixed to the steel beam 10 of the building by means such as welding.

On the other hand, the duct 8 and the air conditioner 9 are installed by inserting the upper end of the hanging metal fitting 7 between the double beams 4 and installing a washer 7a at the upper end.
It is sufficient to attach the upper end of the hanging metal fitting 7 by screwing the nut 7b through the, and to attach the duct 8 and the air conditioner 9 to the lower end of the hanging metal fitting 7 by means similar to the conventional one, even for a large hanging load. Since the support metal fitting body 1 holds the double beams 4 at a constant distance, sufficient strength can be obtained.

In the above embodiment, the threaded hole 3g is formed in the metal fitting 3 and the fixing tool 6 is screwed into the threaded hole 3g, but a small hole 3h is also formed in the lower metal fitting 3 as shown in FIG. Then, the fixture 6 may be inserted into the small hole 3h and fixed by the washer 6a and the nut 6b. The above embodiment has been described with respect to the case of using an angle-type steel double beam 4, as shown in FIG. 12 Figures 10, the lower metal fitting 3 2
By using the individual pieces, it is possible to deal with the double beam 4 using channel type steel.

[0017]

Industrial Applicability As described in detail above, the present invention can be easily manufactured by using a shaped steel in which a double beam for hanging and installing ducts, pipes, air conditioners, etc. on the ceiling of a building is not processed. Therefore, it is possible to significantly reduce the time and effort required for production, as compared with the products processed in the conventional factory.

Further, since a double beam corresponding to an arbitrary suspension load can be easily manufactured on site, it is not necessary to produce and store a plurality of types of double beams in a factory in advance. The cost can be drastically reduced as well as the number of places can be reduced. Moreover, since the unprocessed shape steel is used after being cut to the required length, the surplus portion can be used for other purposes and the material is not wasted.
