JP3879821B2 - Auxiliary fixture for hanging fittings attached to H-shaped steel - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an auxiliary tool for fixing a metal fitting such as a support bar for suspending an air-conditioning duct or a ceiling material from an H-shaped steel.
[0002]
[Prior art]
Conventionally, Japanese Utility Model Laid-Open No. 60-40614 has a support bar mounted on the inside of the support bar in the vicinity of the annular top of the support bar that has a hanging function at the lower end. In addition to being unstable, there is a problem that an anchor is driven into the slab for fixing the support bar.
[0003]
Moreover, in order to attach a specific device to the H-shaped steel, there is an actual Kosho 62-20073 that uses a U-shaped mounting member. The lower flange is sandwiched and fastened with one bolt from the lower side, but its fixing is unstable.
[0004]
Japanese Patent Application Laid-Open No. 10-102669 shows a drawing in which a suspension bolt is attached to a building beam made of H-shaped steel or the like via a mounting member, but there is no description of the specific shape of the mounting member.
[0005]
Further, in JP 2000-336819 A, a crossed H-section steel can be firmly fixed via a spacer by upper and lower fixing members without making a hole in the H-section steel with respect to the structure of a buffer floor support. Although shown, it is too cumbersome to use this for hanging a support bar or the like.
[0006]
Currently, there are metal brackets that can support metal wires directly on structural steel such as construction materials, but there are many parts and lightweight bolt holes for suspension bolts. This requires a lot of man-hours and high costs.
[0007]
[Problems to be solved by the invention]
The present invention intends to provide an auxiliary tool necessary for fixing a hanging metal fitting having a bolt portion to an H-shaped steel flange.
[0008]
[Means for Solving the Problems]
Here, the present inventor viewed the H-shaped steel (1) from the end face side as a fixing aid for a hanging metal fitting attached to the H-shaped steel, with respect to the hanging metal fitting formed with a bolt near the top. A strip-shaped metal plate of a predetermined width is applied to the bottom side of the lower flange (2) of the H-shaped steel, one of them is extended, and the other is bent along the flange surface in a U-shape. A metal U-shaped member (3) provided with a bolt insertion hole (8) of a hanging fitting adjacent to the edge of the lower flange (2) of steel, and (b) a bolt insertion hole ( 8), a metal flat plate (4) placed on the upper surface of the lower flange (2) of the H-shaped steel in accordance with the length of the extended portion of the U-shaped member (3), and (C) a U-shaped A metal liner (5) for filling a space corresponding to an extension of the lower flange (2) of the H-shaped steel surrounded by the member (3) and the flat plate (4); Consists of a combination of the pacer (6), the hanging bracket has led to find what is attachable adjacent the edge of the lower flange (2) of the H-shaped steel.
[0009]
It should be noted that here, the space corresponding to the extension of the lower flange of the H-shaped steel surrounded by the U-shaped member and the flat plate is filled, but the bolt part of the hanging metal fitting is naturally not buried, This means that it is necessary to fill a liner or the like in a stable state between at least a part of the surfaces of the member and the flat plate, and not all the space is filled. Also, if the liner alone is sufficient, do not use spacers.
[0010]
In addition, in the said invention, it discovered that it was suitable for the case of a suspending bolt as a suspending metal fitting.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The hanging fixture fixing auxiliary tool attached to the H-section steel 1 of the present invention has a predetermined width when the H-section steel 1 is viewed from the end face side with respect to the suspension bracket 7 in which a bolt is formed near the top. Place the metal strip on the bottom side of the lower flange 2 of the H-shaped steel, extend one side, fold the other along the flange surface in a U-shape, and lower the lower flange 2 of the H-shaped steel at one extension. A metal U-shaped member 3 provided with a bolt insertion hole 8 of a hanging metal fitting adjacent to the edge of the wire, and (b) an extension of the Ku-shaped member 3 provided with a bolt insertion hole 8 of a hanging metal fitting. An extension of the lower flange 2 of the H-shaped steel surrounded by the metal flat plate 4 placed on the upper surface of the lower flange 2 of the H-shaped steel and the (C) -shaped member 3 and the flat plate 4 according to the length of the part. This is a combination of a metal liner 5 and a spacer 6 filling the upper space, where the H-section steel 1 is the surface of the lower flange. Say those that do not have a flat at an inclination.
[0012]
As described above, the fixing fixture for the hanging metal fitting is composed of the three components (A), (B), and (C), and the U-shaped member 3 that is the component (A) is a belt-shaped metal plate having a predetermined width. Place the bottom side of the lower flange 2 of the H-shaped steel across the entire surface, extend one side, and fold the other side along the flange surface. Adjacent to the edge of the lower flange 2 of the H-shaped steel at one extension. The hanger-shaped member 3 is bent along the flange surface so that the hanger-shaped member 3 is bent along the flange surface. This is to prevent it from falling off.
[0013]
Further, the metal flat plate 4 which is the component (b) is provided with a bolt insertion hole 8 of a hanging metal fitting, and the lower flange 2 of the H-shaped steel 2 is matched to the length of the extended portion of the U-shaped member 3. The combination of the metal liner 5 and the spacer 6 that is placed on the upper surface and is the component (c) is the lower flange 2 of the H-shaped steel surrounded by the U-shaped member 3 and the flat plate 4. It fills the space on the extension. Here, a liner 5 is applied to fill the space, and a spacer 6 is inserted to replenish the remaining gap, but it is not used unless necessary. The spacer 6 balances with the liner 5 and selects and uses a plate thickness corresponding to the remaining gap.
[0014]
Using the above-described auxiliary fixtures for hanging fittings, for example, hanging bolts 7 are inserted into the bolt insertion holes 8 as hanging fittings, and tightened with two upper and lower nuts 9 to fix the hanging bolts 7 to the H-shaped steel. .
[0015]
【Example】
Hereinafter, the present invention will be described more specifically with reference to examples. The case where the height 244 × width 175 × web thickness 7 × flange thickness 11 (all in the following is mm) will be described as the H-section steel 1. In the following, the numerical values in parentheses are for the case of using H 340 × height 340 × width 250 mm × web thickness 9 × flange thickness 14.
[0016]
FIG. 1 illustrates the case where the suspension bolt 7 is fixed to the H-shaped steel flange by a fixing auxiliary tool. The H-shaped steel 1 has a U-shaped member 3, a flat plate 4, a liner 5, and a spacer 6. The suspension bolt 7 is inserted into the bolt insertion hole 8 and fastened with two upper and lower nuts 9.
[0017]
The U-shaped member 3 uses a steel plate electroplating process or a galvanium plate, and has a shape as shown in FIG. 2, and has a plate thickness of 2.3 (2.3), a width of 50 (50), and a length of 205 ( 280), the inner shape of the U-shaped portion is 12 (15), the bolt insertion hole 8 is 13φ (13φ), and its center is 25 (25) from the end edge. The plate thickness 2.3 corresponds to the maximum value that can be bent by a normal processing machine.
[0018]
The flat plate 4 also uses a steel plate electroplating process or a galvanium plate. As shown in the plan view of FIG. 3, the shape is 50 × 50 (50 × 50) and the thickness is 2.3 (2.3). The bolt insertion hole 8 is 13φ (13φ).
[0019]
The liner 5 and the spacer 6 are made of flat aluminum, and the shape thereof is 50 × 15 (50 × 8) as shown in the cross-sectional view of FIG. 4, and the thickness of the liner 5 is 8 (14), and the spacer 6 is 3 (not shown). Use).
[0020]
The suspension bolt 7 and the nut 9 are W-3 / 8 (W-3 / 8).
[0021]
【The invention's effect】
By using the hanging bracket fixing auxiliary tool of the present invention, the hanging bracket can be fixed to the H-shaped steel flange by a simple operation, and the equipment cost is reduced because there is no hole in the H-shaped steel. This has the advantage of shortening the construction period.
