Construction leveling device for spring vibration-isolated foundation chapiter and construction method thereof

Abstract

The invention discloses a construction leveling device for a spring vibration-isolated foundation chapiter and a construction method thereof. The construction leveling device comprises a circle of angle iron frame arranged at the top of a foundation chapiter template; one face of the angle iron frame is arranged parallel to the side wall of the top of the template, and the other face of the angle iron frame is horizontally arranged in an elevation position of a capital of the top face of the template and points towards the inner side of the template. When concrete is poured to the foundation chapiter template, the top face of the concrete is flush with the horizontal top face of the angle iron frame, and the flatness of the foundation chapiter is ensured through the scraping and leveling effect of a darby on the horizontal edge of the angle iron frame. According to the construction leveling device for the spring vibration-isolated foundation chapiter and the construction method, the flatness of the foundation chapiter surface is greatly improved; the quality of the installation of the spring vibration isolation is improved; the foundation for stable and safe operation of equipment is laid; the secondary reworking caused by the fact that the requirement for the flatness is not met is avoided; the engineering economy is improved and construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of spring vibration isolation foundation construction, and specifically designs a spring vibration isolation foundation column head construction leveling device and a construction method thereof. Background technique [0002] At present, spring vibration isolation foundations are widely used for large-scale equipment in industrial plants that use large-scale generators. The foundation form is mainly to install a certain number of vertical spring vibration isolators between the upper foundation top plate of the generator and the lower supporting structure, so that most of the vibration of the generator set during operation is isolated by the spring vibration isolators, so as not to cause damage to the surrounding structures. make an impact. The construction process of the spring vibration isolation foundation is as follows: the foundation column head of the lower structure is constructed first, the spring vi...

AI Technical Summary

Problems solved by technology

Since the surface of the foundation column head cast by ordinary formwork is very uneven, the error is generally about 5mm / 1000mm, so it takes a lot of time to smooth it by using a grinding wheel grinder, which delays the construction period and brings serious losses to the project economy.
