AI Technical Summary

Technical Problem

The upward pulling force exerted by the exhaust pipe on the floor slab in a thermal power plant's steam turbine room leads to insufficient beam design strength and potential failure of embedded parts, posing a safety hazard and requiring reinforcement without disrupting plant operations.

Method used

A beam reinforcement structure using clamping members and through-pieces anchored to the floor slab, combined with auxiliary reinforcement members, to stabilize the beam and embedded parts, allowing for in-service reinforcement and replacement during maintenance.

Benefits of technology

The solution provides stable fixation of embedded parts and reinforces beams without shutting down the unit, reducing operational disruptions and maintenance losses, while maintaining the beam's structural integrity and supporting exhaust ducts.

Abstract

The invention relates to the technical field of structural engineering, and discloses a beam reinforcing structure, an on-beam embedded part reinforcing device and a reinforcing method.According to the scheme, a clamping piece is clamped and fixed to the periphery of a beam body located below a floor, and the beam body is hooped through fixed connection of a penetrating piece penetrating through the floor and the clamping piece, so that reinforcing of the beam body is achieved; when the embedded part is arranged in the on-beam floor slab, the embedded part in the floor slab is fixed through cooperation between the clamping part and the penetrating part (so that the embedded part can be stably embedded in the floor slab); meanwhile, according to the scheme, under the condition that the unit is not stopped, the beam body structure located below the floor slab is reinforced firstly, when the unit is stopped and overhauled, the damaged embedded part which is pre-embedded in the floor slab originally is replaced with a new embedded part in the stopping overhauling time period, the new embedded part is connected with the penetrating part which is installed in advance, and therefore the unit is prevented from being damaged. Compared with a traditional mode that a machine needs to be stopped for reinforcement, the method has the advantage that loss caused to the power plant is greatly reduced.
