Natural draft cooling tower interval precast concrete ring beam and combined inclined strut structure

Abstract

The invention provides a natural ventilation cooling tower interval precast concrete ring beam and combined inclined strut structure. The structure comprises prefabricated ring beam modules, cast-in-place ring beam sections and combined inclined struts. The combined inclined struts are of an integral prefabricated structure formed by combining a column top connecting plate and two herringbone inclined struts and are uniformly arranged along the circumference of the cooling tower, and the bottom ends of the inclined struts are connected with bearing platforms uniformly distributed on a ring foundation; the prefabricated ring beam module is of an inverted-boss-shaped prefabricated structure, the bottom faces of the two sides of the prefabricated ring beam module are supported on the edges of the two corresponding connecting plates in a lap joint mode, and an inverted boss on the lower portion of the prefabricated ring beam module is embedded into a gap between the two connecting plates. The prefabricated ring beam modules and the cast-in-place ring beam sections are arranged at intervals and connected in the circumferential direction to form an integral ring beam structure, and the prefabricated ring beam modules are higher than the cast-in-place ring beam sections. The construction of the spaced precast concrete ring beam and the combined inclined strut structure does not need to erect a support frame, so that the construction difficulty is greatly reduced, the construction cost is saved, the construction safety risk is reduced, and the construction period is shortened.
