The present invention relates to a pipe anchor, and more particularly to a pipe anchor (pipe anchor).

In air-conditioning facilities such as air conditioning and heating, and control systems such as ships, a plurality of equipments and pipes and ducks between them are complicatedly extended. In general, pipes and ducts are longer lengths than their diameters, so they have low rigidity, which makes propagation of vibrations easier, and their natural frequencies are low. It is easy to generate resonance by force.

When resonance occurs in a pipe or the like, vibration of high frequency is caused, so that damage due to fatigue breakdown or the like is generated, as well as considerable noise. This noise, in and of itself, causes environmental pollution as well as fatal consequences in studios and acoustic laboratories.

Accordingly, various dustproof devices are used in the piping system. For example, as shown in FIG. 1, the granular pipe P extending up and down through a layer has a bracket (A) on the pipe anchor A installed as an anchor bolt T at the bottom B. brecket: installed through K) to block solid sound by wail propagation of noise.

That is, the pipe anchor (A) is a dustproof device used for the purpose of anchoring (anchoring) or guide of the granular or horizontal pipe (P), the conventional pipe anchor (A) is roughly shown in Figures 2 and 3 It has a configuration as shown.

2 and 3, the pipe anchor A includes an inner cylinder 61 having a support plate 63 to which a contention bolt B1 to which a bracket K supporting a pipe P is to be coupled is connected. It is accommodated through the elastic member 65 in the outer cylinder 62 provided on (base: 64). The inner cylinder 61 and the outer cylinder 62 are coupled by the fixing bolt B2 in a state where the elastic material 65 is interposed therebetween.

The base 64 is provided with a base plate 66 to be coupled to the anchor bolt (T) of the bottom (B) and protruding upward from the support plate 67 to which the outer cylinder 62 is coupled.

However, in the conventional pipe anchor A, the support plate 63 and the inner cylinder 61, and the respective components 66, 67 and the outer cylinder 62 of the base 64 are coupled to each other by welding in its shape. It can't be. Therefore, a lot of labor for the production, there was a problem of high production cost.

The bigger problem of the pipe anchor (A) manufactured by welding is that the welded part and its heat affected zone (HAZ) are heat treated by quenching and quenching, so that the metal structure is martensitic and has high strength. It is that brittleness becomes large. Since the pipe anchor (A) is used as a vibration isolator in a large vibration environment, such a weld part is easily cracked by fatigue destruction by vibration, and thus its service life becomes very short.

In addition, since the support plate 63 and the base plate 64 each have a flat plate state at both ends of the pipe anchor A, the rigidity is low and the effective vibration cannot be suppressed. In addition, since the base plate 64 can only be coupled to the anchor bolt T at the bottom B only at both ends thereof, its fixing force is weak and it is difficult to suppress the vibration in the lateral direction.

In addition, it is very difficult to couple the coupling bolt (B1) and the fixing bolt (B2) to the outer cylinder 62 and the inner cylinder 61 in the structure, the vibration of the inner cylinder 61 side is solid propagated along the fixed bolt (B2) to the outer cylinder ( Since it is directly transmitted to 62), the installation of pads (68) cannot effectively block it.

In view of such a large number of conventional problems, an object of the present invention is to provide a pipe anchor with a compact structure, small in size, simple to manufacture and install, and excellent in dustproof effect and long service life.

In order to achieve the above object, the pipe anchor according to the present invention is fixed to the bottom and has a land portion (land portion) protruding upward in the center thereof has a base having an inverted cup shape,

A lower cup coupled to the base and having an elastic material contained therein;

Covering the lower cup and the elastic material is characterized in that it comprises an upper cup to be installed coupling bolts.

Such specific features and advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

In FIGS. 4 and 5, the base 30 is configured in the form of a cup or bowl that is roughly inverted with a base plate 31 in a substantially forward direction and a land portion 32 drawn therefrom.

On the land portion 31 of the base 30, a cup-shaped lower cup 20 is placed and coupled. Preferably, the fixing bolt B2 is formed of an elastic pad 50 to block vibration propagation between the two. Are combined through. The pad 50 has a neck (51) entering the through hole 32a having a relatively large diameter formed in the land portion 32 to effectively block the propagation of vibration by the fixing bolt B2.

The lower cup 20 is accommodated in the elastic material 40 in the form of a substantially cylindrical block, preferably the elastic material 40 of the body 41 and the upper cup 10 to fit the inner diameter of the lower cup 20 The head 42 having an inner diameter is provided, and a groove 43 into which the upper end of the lower cup 20 enters is formed between the head 42 and the body 41.

The upper cup 10 which covers the lower cup 20 on the elastic material 40 is inverted to form a cup in which the coupling bolt B1 of the bracket (K in FIG. 1) is coupled through the nut N.

On the other hand, the base plate 31 of the base 30 is formed with a slot (31a) for coupling it to the anchor bolt (T in FIG. 1), preferably this slot (31a) is the four of the base plate 31 It is formed radially inward at the corners. In addition, it is preferable that the base plate 31 is provided with ribs 31b which are bent and molded to increase its rigidity.

The pipe anchor of the present invention configured as described above has no welding at all in construction and installation. That is, the base 30 and the upper and lower cups 10 and 20 may be manufactured by press molding of sheet materials, respectively, so that the manufacturing of the base 30 and the upper and lower cups 10 and 20 may be very easy, and also very resistant to fatigue due to vibration.

In addition, the lower cup 20 and the base 30 can be coupled by a fixed bolt (B2) in which vibration propagation is blocked therebetween, and the upper and lower cups 10 and 20 and the elastic member 40 are simply stored and covered. It can be combined only by covering, and can perform an adhesion as needed.

In particular, by forming a groove 43 between the body 41 and the head 42 of the elastic material 40 to insert the upper end of the lower cup 20, the pipe anchor of the present invention is effective in dustproof in all directions.

In addition, the degree of freedom of the elastic member 40 is also significantly greater than that of the conventional pipe anchors, which are constrained and restricted between the inner and outer cylinders, so that the pipe anchor of the present invention can absorb vibration even by shear deformation of the elastic member 40. . As a result, the inflow rate can effectively damp the vibration wave, thereby significantly increasing the dustproof effect.

According to the above and the present invention, the pipe anchor is provided with a simple, compact, excellent dustproof effect and a long service life.
