Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting bracket that can be easily and reliably attached to a channel steel of an appropriate size by simply adjusting the same item as appropriate.

[Prior art and its problems, etc.] Recently, there are various types of mounting brackets for attaching brackets for supporting corrugated lighting panels etc. to channel steel, but the size of the channel steel (size of cross section) When changing as needed, there was no one that was the same and could be easily attached to any size.

[Means for Solving the Problems] Therefore, as a result of intensive research in order to solve the above-mentioned problems, the inventor has developed the present invention by applying the bolts to the lower side of the upper flat part on which the bolts are erected. A folded bent part and a hanging part from the other end are respectively formed to form the metal fitting body, and a tightening bolt is screwed into the hanging part, and the folded bent part is formed above one end of the lower flat part and perpendicular to the other end. By making the vertical pieces of the secondary fittings each formed into a mounting fitting detachably and vertically adjustable on the underside of the hanging part, when the size of the channel steel changes appropriately, The height is adjusted by raising and lowering the secondary metal fitting, and the width is determined by the degree of tightening of the tightening bolt, so even if the same item is the same, it can be installed easily and reliably by following its size. etc., has been solved.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

A is a metal fitting main body, in which a folded bent part 2 is formed below one end of the upper flat part 1 (the right side in Figs. 2 and 3), and the other end (the right side in Figs. 2 and 3).
A hanging portion 3 is provided from the left side in the figure.

4 is a mounting bolt, and the bolt head is attached to one or more internal threads provided on the hanging portion 3.
On the outside (left side in Figures 2 and 3),
The bolt shaft portion is screwed together.

Reference numeral B denotes a sub-metal fitting, in which a folded bent part 6 is formed above one end of the lower flat part 5 (the right side in Figs. 2 and 3), and the other end (the left side in Figs. 2 and 3). ) is formed with a vertical piece 7 pointing downward (see drawing) or upward.

The vertical piece 7 of the secondary metal fitting B is provided below the hanging part 3 of the metal fitting main body A so that it can be attached and removed with a bolt and nut 9 and can be adjusted up and down. In this specific embodiment, as shown in the figure, an elongated hole 8 facing vertically is bored in the lower side of the hanging part 3, and a through hole is simply formed in the vertical piece 7 to allow the elongated hole 8 to be opened. It is fixed with a bolt/nut 9 through the vertical piece 7.
is provided so as to be vertically adjustable with respect to the hanging portion 3. Alternatively, contrary to the embodiment, a long hole 8 may be formed in the vertical piece 7.
It may also be constructed such that it can be freely attached and detached with bolts and nuts 9 and can be adjusted up and down.

Reference numeral 10a denotes a bolt, the lower end of which is erected on the upper flat portion 1 by welding, caulking, or the like. 10b is a nut.

In the figure, reference numeral 11 indicates a channel steel having a U-shaped cross section, and is provided on the top or side of the structure. Reference numeral 12 is a long or appropriate length metal receiving fitting, and a gutter-like portion 12b is integrally formed on at least one side (provided on both sides in the drawing) of the portal portion 12a.

13 is a corrugated bracket, 14 is a corrugated gasket for a joint made of hard synthetic rubber or synthetic resin, 15 is a corrugated lighting plate made of transparent glass or synthetic resin, 16 is a corrugated joint cover, 17a is a bolt, and 17b is a nut. It is.

[Effect of the invention] In the invention, the folded bent portion 2 is provided below one end of the upper flat portion 1 on which the bolt 10a is erected.
A hanging part 3 is formed from the other end of the metal fitting body A.
A tightening bolt 4 is screwed into the hanging part 3, and a bent part 6 is folded upward from one end of the lower flat part 5.
By making the vertical pieces 7 of the sub-metal B, each of which has a vertical piece 7 formed from its other end, into a mounting bracket that is detachably and vertically adjustable on the lower side of the hanging part 3, it is possible to It can be easily and quickly attached to the channel steel 11 of the size, secondly, it can be attached very firmly, thirdly, it can be easily removed, and fourthly, the structure is simple and can be provided at low cost. It has the effect of

To explain these effects in detail, first of all, whether the cross-sectional size of the channel steel 11 is large as shown in Fig. 2 or small as shown in Fig. 3, it can be can respond well, i.e.
Corresponding to the size of each cross section, its height is determined by raising and lowering the secondary fitting B with respect to the hanging portion 3, and its width is determined by the degree of tightening of the tightening bolt 4.

In this way, even if the mounting brackets have the same configuration,
It can be easily and reliably attached to the channel steel 11, and even if the mounting bracket of the present invention has one type of size and shape, it can be easily and easily attached to the channel steel 11 of various sizes. It can be installed reliably and has great versatility.

Further, as shown in FIG. 2, the mounting bracket of the present invention is attached by engaging the folded bent portions 2 and 6 with the upper and lower edges of the channel steel 11 and tightening the tightening bolts 4. Can be attached to channel steel 11.

In particular, by tightening with the tightening bolt 4, this tightening force is applied to the channel steel 11 on the condition that it is held by the folded bent parts 2 and 6 on the opposite side of the tightening bolt 4. can be strongly pressed, and the grooved steel 11 can be held between the left and right sides by the metal fitting main body A, the secondary metal fitting B, and the tightening bolt 4, and an extremely strong installation is possible.

Furthermore, since the folded bent parts 2 and 6 are made by bending plate pieces, they are not in point or line contact with the structural material like conventional hook bolts, but are in almost surface contact, and do not wobble when engaged. It has advantages such as a strong engagement.

Further, the present invention has the advantage that it can be easily removed by loosening the tightening bolt 4, and can be used any number of times.

Further, the present invention has an extremely simple configuration, is easy to manufacture, and can be provided at low cost. Furthermore, if the present invention is used to construct a daylighting roof or a daylighting wall, it will be possible to perform work easily and safely even at high places.
