High damping structure

This creation is related to the damping structure, and more specifically to a highly damped structure.

In the so-called high-tech (such as wafer manufacturing industry) factory, due to the precise structure of its products, in order to ensure the quality of the products produced, it is necessary to effectively control various factors of the working environment, such as temperature, humidity and dust-free environment. In addition, the effects of vibration energy, including the automatic machine itself from the job, or the earthquake may be considered. For this reason, how to provide a stable and dynamic stiffness damping structure between the automatic implement and the ground is an important issue. Especially when the automatic machine weighs several tons or more, the general spring structure or the hydraulic system is not suitable because it is difficult to support.

In view of this, the main purpose of the present invention is to provide a high-damping structure capable of supporting a weight of several tons or more and providing a stable and good dynamic rigidity effect.

In order to achieve the above object, the high damping structure provided by the present invention comprises a rigid base, a damping unit and a bonding medium layer. Wherein the rigid base a receiving groove having an upper opening, a closed groove bottom and an inner annular surface surrounding the closed groove bottom; the damping unit is disposed in the receiving groove of the rigid base and includes opening the concrete from the upper opening a concrete structure formed by being filled into the cavity and being dry-laid; the bonding medium layer is formed by applying a bonding agent to the groove bottom and the inner annular surface of the cavity, and the bonding dielectric layer is located on the rigid base Between the damping units.

Thereby, under the action of the alternating load, a good resistance to dynamic displacement can be obtained, thereby reducing the influence of vibration.

In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the drawings.

FIG. 1 shows a high damping structure 100 according to a preferred embodiment of the present invention. The high damping structure 100 is capable of supporting an implement M having a weight of several tons or more and provides good dynamic rigidity. It includes a rigid base 10, a support structure 20, a bonding dielectric layer 30 and a damping unit 40. Wherein: the rigid base 10 is assembled into a solid steel material having a receiving groove 12, and the receiving groove 12 is surrounded by a closed groove bottom 12a and an inner annular surface 12b surrounding the closed groove bottom 12a, and the groove The pocket 12 has an upper opening.

One end of the support structure 20 is fixed to the bottom surface of the rigid base 10, and the other end is fixed to the ground G. In this embodiment, the support structure 20 is composed of a plurality of H-shaped steels 22 and a plurality of damping spacers 24, wherein the H-shaped steels 22 The two ends are respectively fixed to the rigid base 10 and the ground G. The manner in which the H-shaped steel 22 and the rigid base 10 are fixed may be welded or locked (refer to FIG. 1); the damping spacers 24 are The rubber is made up and disposed between the H-shaped steel 22 and the bottom surface of the rigid base 10, and the arrangement of the damping spacers 24 is selected depending on the requirements. The support structure 20 can slightly position the implement M away from the ground G.

The bonding dielectric layer 30 is formed by applying a bonding agent to the groove bottom 12a and the inner ring surface 12b of the cavity 12 of the rigid base 10. The bonding agent may be an epoxy resin material, a polyethylene material, or other materials having equivalent characteristics.

The damper unit 40 is disposed in the cavity 12 of the rigid base 10. In the embodiment, the concrete structure 42 includes a plurality of steel meshes 44, a high-strength fiber layer 46 and a damper surface material 48. The concrete structure 42 is filled into the tank 12 by concrete and formed as a dry solid. Preferably, in the process of pouring concrete, an air-entraining agent is added as an example but not This is a limited anti-shrinkage additive for the purpose of reducing the occurrence of shrinkage cracks in the concrete; the steel mesh 44 is pre-laid in the process of pouring the concrete and arranged in a stacked manner to improve the overall solidity of the concrete structure 42. The high-strength fiber layer 46 is disposed on the top surface of the concrete structure 42 to maintain the concrete moisture to delay the concrete surface condensation, and to fill the uneven surface of the concrete; the damping surface material 48 is disposed at the high strength The top surface of the fiber layer 46. In the present embodiment, the damping surface member 48 is made of epoxy resin and has a repairing surface effect so that the implement M can be stably mounted on the high damping structure 100. on.

The high-damage structure 100 can support the implement M having a weight of several tons or more not only because of the large-sized concrete structure 42 but also the dynamic displacement when the load M is generated between the implement M and the ground G, that is, The high damping structure 100 provides good dynamic rigidity and reduces the effects of vibration. Moreover, the bonding dielectric layer 30 is finally located between the rigid base 10 and the damping unit 40, and has the effect of reducing the crack expansion between the concrete structure 42 and the wall surface of the rigid base 10 of the rigid base 10. The overall structure of the high damping structure 100 is made denser and firmer. The above-mentioned cracks are caused by the chemical reaction of cement and water during the condensation and hardening of large-volume concrete and release a large amount of heat (commonly known as "hydration heat"), which will lead to an increase in the temperature of the concrete block. However, when the temperature inside the concrete block differs greatly from the temperature outside, the temperature stress or temperature deformation formed exceeds the tensile strength or ultimate tensile strain of the concrete at the time, and peeling occurs after the concrete shrinks. Phenomenon, which in turn forms cracks. The bonded dielectric layer 30 of the present invention has the effect of reducing crack enlargement.

2 shows a high damping structure 200 according to another preferred embodiment of the present invention. The high damping structure 200 also includes the rigid base 10, the support structure 20 and the bonding medium layer 30 of the above embodiment. The difference is that the damper surface 52 of the damper unit 50 constituting the high damper structure 200 is composed of an adhesive layer 52a and an epoxy resin layer 52b, wherein the adhesive layer 52a is a polyamide or ruthenium. The material is laid on the top surface of the high-strength fiber layer 54, and the epoxy layer 52b It is provided on the adhesive layer 52a, and the purpose is also to repair the surface in order to securely mount the implement M. The concrete structure 56, the wire mesh 58, and the high-strength fiber layer 54 of the damper unit 50 are the same as those of the above embodiment, and will not be described herein. The high damping structure 200 also provides good dynamic rigidity.
