Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a vibration-proof hanger for suspending and supporting field edges, piping ducts, mechanical devices, etc. from the ceiling.

(B) Prior Art In recent years, interest in sound pollution has been increasing year by year, and sound and vibration proof measures have become a major problem, especially in schools, hospitals, offices, apartment complexes, various stores, and entertainment facilities.

Therefore, various anti-vibration hangers for suspending and supporting air-conditioning equipment, ventilation systems, piping ducts, and other mechanical devices from ceilings have been developed and put into practice. However, conventional anti-vibration hangers have a metal frame consisting of both upper and lower sides, which is fixed to the ceiling slab with bolts and inserts on the top plate of the metal frame, and anti-vibration rubber is placed on the top of the bottom plate of the metal frame. Place a bolt through the vibration isolating rubber and the through hole in the bottom plate of the metal frame, and fix the vibration isolating rubber inside the hollow of the metal frame with a nut.
Bolts hanging below the metal frame are used to connect piping ducts and other supporting members. In other words, the work process is complicated, and depending on the size, it is necessary to insert one's hand into the hollow space of a metal frame measuring 70 mm in length, 50 mm in width, and 40 mm in depth to perform attachment work.

(c) Purpose of the invention The present invention was made in view of the above circumstances, and it is extremely simple and allows work to be carried out efficiently, and it also improves the efficiency of air-conditioning equipment, ventilation equipment, piping ducts, and other machinery. The object of the present invention is to provide a new anti-vibration hanger that can reliably suspend and support a device on a ceiling.

(d) Structure of the invention The present invention is a vibration-proof hanger, in which a flange is provided at one end of a support rod, a vibration-proof rubber is fixed to the upper part of the flange, and a connecting rod is removably locked on the top surface of the vibration-proof rubber. This hanger is characterized in that the connecting rod that comes into contact with the vibration isolating rubber is formed into a curved shape.

That is, the suspension support rod, which is fixed at one end by an insert, is formed integrally with the vibration isolating rubber, and can be easily attached by simply hooking the curved part of the upper part of the connecting rod to the rounded part of the upper surface of the vibration isolating rubber. Once it is set up, all that is left to do is connect the connecting rod and the duct, making the work process much simpler and more efficient than conventional systems.

(E) Embodiments The configuration of the present invention will be explained in detail based on embodiments shown in the drawings.

Figures 1 to 4 show the first embodiment of the present invention, where Figure 1 is a front view, Figure 2 is a plan view of the lower part of the connecting rod, Figure 3 is a right side view, and Figure 4 is a front view. is a left side view.

The support rod 1 is provided with a screw 2 at its upper end, a flange 3 at its lower end, and a vibration-proof rubber is fixed to the upper surface of the flange 3.

The vibration isolating rubber 4 has an upper surface formed in a rounded shape,
The center portion 5 and both side edges 6, 6 of the upper surface are formed in a convex shape, and the surface of the remaining portion 7 of the upper surface is formed with fine irregularities.

Next, the band-shaped connecting rod 8 has one end formed in a rounded hook portion 9 and is bent inward 10, and the other end is bent to face the curved portion 10 to form a low surface portion 11. do. Bolts 12 are attached to the bottom part 11.
is passed through from below and secured with a nut 13.
Note that the connecting rod 8 is reinforced by providing a rib 14 at the center in the longitudinal direction.

To use this embodiment, first, the suspension support rod 1 to which the vibration isolating rubber is fixed is fixed to the ceiling slab with an insert 18, and the curved part of the connecting rod 8 is attached to the upper surface of the vibration isolating rubber 4. All you have to do is attract 10. Since the vibration isolating rubber 4 has a rounded upper surface, the curved portion 10 of the connecting rod 8 is formed in the vibration isolating rubber 4.
Since the upper surface of the vibration isolating rubber 4 has a convex central portion and both side edges, one end 9 of the connecting rod 8 is held between the convex portions and is securely engaged. Stop. Field edges, piping ducts, etc. can be connected as appropriate with bolts hanging from the bottom.

In the above embodiment, the bolt is passed through the bottom part, but as shown in FIG.
A slit 15 may be formed in the slit 15, and the bolt 12 may be slid into the slit 15 and fixed with a non-slip washer 16 and a nut 13.

What is shown in FIG. 5 is a second embodiment.

In this embodiment, the suspension support rod 1 to which the vibration isolating rubber 4 is fixed is similar to that of the first embodiment, but the connecting rod 8a is formed of a rod. , one end is curved as in the case of the first embodiment, the lower end of this curved portion 10a is suspended downward at a position opposite to the center of the curved portion 10a, and a female thread 17 is provided at the end.

To use this example, connect the connecting rod 8a
A supporting member for supporting a duct or the like may be fixed to the female thread 17 at the lower end of the connecting rod 8a by hooking the curved portion 10a on the upper surface of the vibration isolating rubber 4. Although the drawing shows an example in which a female thread 17 is provided at the lower end of the connecting rod 8a, a male thread may be provided on the peripheral surface of the connecting rod 8a.

(f) Effects of the invention The present invention is simple because it is only necessary to fix the suspension support rod to which the vibration isolating rubber is fixed to the ceiling slab as described above, and then hook the connecting rod to the vibration isolator. You can proceed with your work efficiently.

Moreover, the vibration-proof rubber has a rounded upper surface, and the curved part of the connecting rod is attracted to the rounded part, so even if there is a small gap between the ceiling slab and the vibration-proof rubber, the vibration-proof rubber can be It can be easily pulled by sliding it from the tip of the curved part along the shape of the top surface of the swinging rubber, and the one end 9 of the connecting rod can be held between the convex parts and securely locked. It is.

The effects obtained by the above-mentioned structure are extremely superior and cannot be obtained with conventional anti-vibration hangers.

Note that by providing fine irregularities on the surface of the anti-vibration rubber, the effect of expanding the absorption frequency band can be obtained.

Furthermore, the shape of the vibration isolating rubber only needs to have a rounded top surface, and the shape of the other parts is not critical.

Further, the connecting rod may be made of metal or a composite material thereof, as long as it is hard and durable.
