More specifically, the reciprocating compression spring inner cylinder (80) spring compression plate (81) fixed to the inner cylinder buffer pad (82) spring pressure plate (83) compression spring (84) spring pressure plate (85) buffer rubber pad (86) Reciprocating compression spring reciprocating compression spring damper, characterized in that the inner cylinder connecting hardware (87) reciprocating compression spring outer cylinder (90) is composed of a spring compression plate 91, the outer cylinder connecting hardware (92) fixed to the outer cylinder ( 100); It relates to a manufacturing method and a reinforcement method using the same.

Description

Drop Preventing Device

The present invention relates to a fall prevention device provided with a reciprocating compression spring damper for preventing the loss of valuable life and property by preventing the fall of the bridge deck due to repeated lateral load during the earthquake.

In the event of an earthquake, lateral pressure acts repeatedly, causing the bridge deck to fail, resulting in the loss of valuable lives and property.

The object of the present invention is as follows.

First, it is an object of the present invention to prevent the loss of valuable people and property by preventing the fall of the bridge deck when an earthquake occurs.

     Second, another object of the present invention is to provide a reciprocating compression spring damper that can minimize the unnecessary anxiety composition of the user by providing a reciprocating compression spring damper having a relatively beautiful appearance.

Third, it is another object of the present invention to provide a reciprocating compression spring damper having a low construction cost as well as an air shortage by allowing the construction of a new bridge as well as an existing bridge.

Technical configuration of the present invention created to achieve the above object is the same as the contents shown in Figs.

Technical effects of the configuration of the present invention are as follows.

First, in case of an earthquake, it is possible to prevent the fall of the bridge deck to prevent the loss of valuable lives and property.

     Second, it is possible to provide a reciprocating compression spring damper that can minimize the unnecessary anxiety composition of the user by providing a reciprocating compression spring damper having a relatively beautiful appearance.

Third, it is possible to provide a reciprocating compression spring damper having a low construction cost as well as an air shortage by allowing the construction of a new bridge as well as an existing bridge.

1 to 16 show a specific embodiment of the present invention.

The scope of protection of the present invention is not limited to these embodiments, and various design changes, additions or deletions of well-known technologies, and simple numerical limitations do not limit the technical scope of the present invention. Clarify belonging.

1 to 16 show a specific embodiment of the present invention.
