Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for fixing a support beam to which an arbitrary member is attached.

(Prior Art) For example, there are a wide variety of suspension bands for various types of piping, but not much has been devised regarding support beams for attaching such metal fittings.

(Technical Problem) The problem of the present invention is to make it possible to provide a support beam that can bear the strength at an appropriate position when, for example, there are no suitable parts or locations for attaching piping, etc. as mentioned above. There is a particular thing.

(Technical means) In order to achieve the above object, a support beam 4 having a substantially U-shaped cross section is attached to the main body 1, which has a lower piece 2 for locking at the lower part and an upper piece 3 approximately parallel to this at the upper part. Alternatively, by opening the window 5 located facing left so that the cross-section is roughly shaped, the projecting portions formed on both sides of the window 5 can be used as the resistance pieces 6, 6' that enter into the support beam 4, and the resistance pieces 6, 6 can be ' are the upper and lower edges 4a of the support beam 4
The upper piece 3 is provided with a fixing screw 7 for tightening the support beam 4.

(Example) To explain with the illustrated example, in FIGS. 1 to 3, the main body 1 is made of a metal material or the like having strength to withstand the tightening force of the fixing screw 7, and the mounting base has a locking edge b. It has a lower piece 2 at the bottom that locks on the material B,
The upper part has a slightly wider upper piece 3 which is parallel to the lower piece 2.

A window 5 is provided in the center of the main body 1 and is large enough to allow the support beam 4, which has a substantially U-shaped cross section, to pass through in both left and right directions. It is punched into a shape having a recessed portion 5a into which it can be inserted. At the time of punching, resistance pieces 6 and 6' that protrude inward from the recessed portion 5a are formed at the same time, and a space with a width necessary for tilting the support beam 4 is formed between both pieces 6 and 6'. 5b is provided.

The drag pieces 6, 6' are support beams 4 having a substantially U-shaped cross section.
The support beam 4 extends into the channel 8 and has a height substantially equal to the distance between the upper and lower edges 4a of the support beam 4. Furthermore, a female screw hole 9 is formed in the upper piece 3, into which a fixing screw 7 such as a butterfly screw is screwed. Reference numeral 10 indicates an operating portion of the fixing screw 7, reference numerals 11 and 11 indicate reinforcing protrusions of the main body 1, and reference numeral 12 indicates a locking portion at the tip of the lower piece.

In the example of FIGS. 1 to 3 constructed in this manner, the support beam 4 can be set by inserting the support beam 4 from the side into the window 5 formed in the center of the main body 1.

In the example shown in FIGS. 4 and 5, the support beam 4 is vertically moved from bottom to top and positioned at the window 5.
This is a modification of the example shown in the figure, which was a sliding method from the side. Therefore, the lower piece 2 is divided into left and right parts, with a passage space 13 between them, and the width of the space 5b is set wider than the width of the support beam 4. Since the other configurations may be the same as those described above, the reference numerals will be used and detailed explanations will be omitted.

In the example shown in FIGS. 4 and 5, the support beam 4 can be set by vertically moving it from the space 13 into the window 5 while maintaining a substantially horizontal position.

(Function of the device) When using the device shown in FIG. ′ is inserted into the main body 1 and arranged in a cross-shape,
When the previously loosened fixing screw 7 is tightened, its tip will spiral toward the edge 4a of the support beam 4, and as a result, the support beam 4 will be tightened between the main body lower piece 2, the resistance piece 6, and the upper piece 3. and can be firmly fixed.

On the other hand, in the embodiment shown in FIG. 4, the support beam 4 is moved from below through the passage space 13 into the window 5, and then moved laterally to lock the upper part of the edge 4a in the recess 5a. It is sufficient to insert the resistance pieces 6, 6' into the channel 8, and then hook the locking part 12 onto the mounting base material B and tighten the fixing screw 7.

(Effect of the invention) Therefore, according to the invention, by fixing the support beam 4 having a substantially U-shaped cross section to a suitable mounting base material B, it can be firmly mounted in a cantilevered manner or at both ends. Even when the member to which the attachment is to be attached does not exist at the desired location, an attachment site can be provided. In particular, with this invention, the support beam 4 can be installed in either the left or right direction, so it can be installed in either the left or right direction.
It does not require preparation of different types, reduces costs, and has outstanding features such as no confusion on site.
