Some embodiments of the invention will now be described in detail with reference to the accompanying drawings.

In adding reference numerals to the elements of each drawing, it should be noted that the same elements are designated by the same reference numerals as much as possible even though they are shown in different drawings. In describing the present embodiment, when it is determined that a detailed description of a related well-known configuration or function may obscure the gist of the present embodiment, the detailed description thereof is omitted.

The hybrid anti-vibration system 1 for horizontal piping according to the present invention can be applied in various embodiments depending on the structure and shape of the horizontal piping 100 and the peripheral member which are supported members.

First, FIG. 2 is a front sectional view of a hybrid anti-vibration system 1 for horizontal piping according to a first embodiment of the present invention, and FIG. 3 is a perspective view of the horizontal piping 100 removed from FIG. 2.

Referring to both figures together, the hybrid dustproof system 1 is framed from the top plate 110, the middle plate 120 and the bottom plate 128 from top to bottom. The upper plate 110 has an upper portion 116 and a central portion such that a concave shape receiving portion 118 for receiving the supporting assembly 102 composed of the supporting portion 104, the connecting portion 106, and the base 108 is formed at the center thereof. 114 is formed, and below the central portion 114, a flat bottom 112 is formed integrally therewith. The upper portion 116 is bent toward the receiving portion 118 in the central direction, and the large area base 108 rests on the lower surface 112, so that the support assembly 102 can be pulled out of the receiving portion 118 without fear. It stably supports the horizontal pipe (100). The support assembly 102 and the upper plate 110 are just examples, and various modifications are possible.

The intermediate plate 120 includes a rectangular base 122 bent to form a concave receiving portion 126 in the center and an upper surface 124 extending from both ends of the base 122. The first elastic member 2, which is a feature of the present invention, is accommodated in a compressed state between the lower surface of the lower portion 112 of the upper plate 110 and the upper surface of the base 122 by the load of the horizontal pipe 100. 126 is accommodated.

As shown in FIG. 4, the first elastic member 2 is, for example, an 11-layer composite elastic member in which the slim metal plate 20 and the slim rubber plate 22 are alternately stacked. When rubber is applied as an elastic member, the vertical strength when a vertical load is applied is stronger as the thickness of the rubber is thinner. Therefore, if the elastic member of the same height, it is advantageous to insert another member to reduce the thickness of the rubber and compensate for the reduced thickness. In the present invention, the metal plate 20 is used as another member. The metal plate 20 includes steel, copper or aluminum, but steel is advantageous in terms of strength and economy.

When the metal plate 20 and the rubber plate 22 are alternately stacked, not only the vertical strength is increased, but also when the lateral force is applied, the impact is absorbed by the metal plate 20 and the rubber plate 22 is deformed, thereby converting the accumulated force into an elastic force. Since it has a tendency to return to the original state by using, the first elastic member 2 can be easily returned to the horizontal balance state before the change. In addition, when the material of the horizontal pipe 100 is metal (steel), in order to prevent lateral displacement due to long-term use, it is preferable to include an elastic member made of a material of at least the strength of the horizontal pipe (100). Also in this respect, the structure of this invention which inserts the metal plate 20 between the rubber plates 22 exhibits sufficient merit.

The first elastic member 2 of FIG. 4 may be manufactured in a circular or quadrangular shape. FIG. 5 shows several types of first elastic members 2 applied to the hybrid dustproof system of the present invention when the first elastic member 2 is circular. The first elastic member 2 may be manufactured in a solid shape without an opening as shown in FIG. 5A. In the case of the solid type, when a horizontal load is applied, an evenly distributed load is generated so that horizontal displacement is stably generated and does not fall. 5B and 5C are open types having an opening 24 formed at the center thereof, and the larger the load of the horizontal pipe 100, the smaller the opening 24 is used, and the deformation amount of the horizontal pipe 100 is large (for example, A metal opening having a large thermal expansion coefficient) is used.

2 and 3, a pair of second elastic members 4 are installed in both side spaces between the intermediate plate 120 and the lower plate 128 with the first elastic member 2 in the middle. do. The second elastic member 4 is a spring-rubber dustproof mount, and as shown in FIG. 6, a spring accommodated in the flat rubber 40 and the hole 44 of the accommodation protrusion 42 of the rubber 40 ( 46). In the illustrated example, four holes 44 can be modified in various ways, such as providing eight holes. Spring-rubber mounts mainly use springs to reduce vibration, absorb vibration in the up and down direction, use open type when horizontal vibration and reaction forces are not large, and use high vibration and high efficiency dust isolation. Use a closed type that damps transverse vibrations. The spring 46 is an elongate spring of a compression spring or hourglass type with a constant diameter.

A bolt 130 and a nut 132 are installed on side surfaces of the second elastic member 4 as fastening members for fastening the intermediate plate 120 and the lower plate 128.

In the present invention, by installing the first elastic member 2 adjacent to the lower middle portion of the horizontal pipe 100, the lateral load applied to the horizontal pipe 100 is directly the first elastic through the upper plate 110 The first elastic member 12 is configured to be transversely displaced in the receiving portion 126 to return to its original shape while absorbing the lateral load, and thus the lateral vibration applied to the side of the horizontal pipe. Particularly resistant to deformation. In addition to the first elastic member 2, the second elastic member 4 serves to assist dust protection against side loads, and in particular, a plurality of second elastic members 4 are installed in a balanced manner in close contact with the ground, which is a fixed surface. Function to prevent vibration.

7 is a front view of the hybrid anti-vibration system 1 for horizontal piping according to the second embodiment of the present invention. 2 is different from the first embodiment of the horizontal pipe 100, the support pipe 110b of the "∩" shape is installed around the outer periphery of the horizontal pipe 100, the upper plate (110a) by making a flat plate of the horizontal pipe 100 This is to support the lower part immediately. Since the support pipe 110b presses and supports a part of the upper and side surfaces of the horizontal pipe 100, the support assembly 102 may delete it. The second embodiment also has the same effect as the first embodiment.

Next, FIG. 8 is a front view of the hybrid dustproof system 1 for horizontal piping according to the third embodiment of the present invention. The difference from the second embodiment is that the anti-vibration structure does not directly support the horizontal pipe 100. For example, four horizontal pipes 100 are mounted on a common mount H such as an H beam and attached to a wall. It is the point that the pair of vibration isolation systems 1 provided in the triangular-shaped support stand S supported both ends of the common mount frame H. As shown in FIG. In this case, the anti-vibration system 1 functions to absorb the lateral and vertical vibrations of the common mount H on which the horizontal pipe 100 is placed on the same principle as in the previous embodiment.

While the preferred embodiments of the present invention have been described above, various modifications may be made to the present invention. For example, a plurality of first elastic members 2 may be installed. Alternatively, the intermediate plate 120 may be removed, and the first and second elastic members 2 and 4 may be installed between the upper and lower plates 110 and 128. The shape, size, numerical value and material of the members illustrated in the detailed description and drawings of the present invention should not be construed as limiting the scope of the present invention.
