Technical Field
[0001] The utility model relates to the technical field of foundation embedded parts remedial construction, in particular to a vibration-resistant reinforced concrete foundation post-installed steel plate structure. Background Art
[0002] Foundation embedded parts are important structures for fixing equipment, and are also an indispensable part for ensuring the normal operation of equipment, especially operating vibrating equipment. During the construction process, due to the influence of the process, foundation embedded parts are often missed or buried incorrectly, and post-embedded parts have to be installed. Ensuring the vibration resistance and anchoring strength requirements of post-embedded parts, achieving stability and reliability of post-embedded parts, and thus achieving normal operation of equipment are the basic requirements for the remediation of foundation embedded parts. At present, remedial methods such as core drilling to reset embedded parts and expansion bolts to replace embedded parts are usually used. However, the above methods have the disadvantages of not being suitable for the remediation of thin plate foundation embedded parts; poor anti-vibration effect; poor integral connection and stability between embedded parts and foundation.
[0003] To this end, the present application designs a vibration-resistant reinforced concrete foundation post-mounted steel plate structure to solve the above-mentioned problems. Utility Model Content
