Bridge Lifting Support Bracket

Abstract

A bridge lifting support bracket is disclosed, which comprises a supporting mechanism, comprising a bracket having a depressed area at a face thereof and a raising portion disposed at two sides of the bracket, respectively; and at least two jacks, disposed on a bottom face of the raising portions, respectively. As such, a space for receiving a jack properly is secured by digging out a space of a concrete protection layer of a lower structure and using a supporting mechanism cooperating therewith when only a small space or a closely tight bonding with no seam existing between a bridge and a pier, whereby a raising process of the bridge may be safely performed.

Description

technical field [0001] The present invention relates to a support bracket for jacking up a bridge, especially a space that can be used to remove the concrete protective layer of the lower structure when there is only a small space at the support of the bridge and the pier or if there is no gap in the close arrangement. The cooperation with the support mechanism strives for enough space for placing the jack, so as to achieve the jack support bracket for the bridge jacking operation under the condition of safety. Background technique [0002] Most of the general engineering circles use it on the outside of the reinforced concrete structure of the bridge abutment or pier column cap beam, and use bolts to anchor the support bracket or other support systems to establish a working platform for setting jacks. [0003] However, this construction method also has concerns about its construction safety. When the upper structure of the bridge is lifted, its weight is transferred and dis...

Problems solved by technology

[0003] However, this construction method also has concerns about its construction safety. When the upper structure of the bridge is lifted, its weight is transferred and distributed to the jacks placed under the bridge. At this time, each jack can bear a load ranging from tens of metric tons to as much as The strength of the concrete at the anchorage depends on the service life of the bridge body and the influence of the environment. The variation of the concrete strength is large. Therefore, the risk factor of the project is greatly increased, and the advantages of construction trailers are added. Inferiority and flaws in the support system, such as improper design, construction errors, etc., once the jack support fails, it may cause a chain reaction, resulting in damage to the bridge structure, and even endanger the safety of life and property in severe cases. If repair costs, The time required and the traffic inconvenience caused, the loss is even more difficult to estimate
