Balance weight loading device and loading method thereof

Abstract

The invention relates to a balance weight loading device and a loading method thereof, relating to the technical field of test detection of prefabricated parts. The invention aims at solving the problems that the working efficiency is reduced, and the experimental cost is increased because an existing loading test method has a limited application range and depends on a fixed test site. The balance weight loading device comprises a reinforced concrete weight counter-force frame, wherein the reinforced concrete weight counter-force frame comprises a pair of pillar bodies, a plurality of tie beams, a yard beam, an auxiliary beam and a plurality of brackets, the pillar bodies are vertically and oppositely arranged, the pillar bodies are connected to the bottom ends of the pillar bodies, the yard beam transversely stretches across and fixedly connected to the top ends of the pillar bodies, and the auxiliary beam is fixedly connected to the bottom of the yard beam and is parallel with the pillar bodies; and the brackets are fixedly connected to the outer sides of the pillar bodies. The loading method comprises the following steps: bridging a test beam on buttresses and between two pillar bodies of the reinforced concrete weight counter-force frame; putting a reverse-jacking device between the test beam and the auxiliary beam, and pre-forming a gap between the reverse-jacking device and the auxiliary beam; and applying load to the test beam through the reverse-jacking device, applying the maximum load to balance weight objects at the bracket on two sides of the pillar bodies, and observing and recording data tested by the reverse-jacking device.

Description

technical field [0001] The invention relates to the technical field of test and detection of prefabricated components, in particular to a loading counterweight device and a loading method thereof. Background technique [0002] With the continuous development of bridge engineering standardization and factoryization, there are more and more test and inspection items for prefabricated beams; among them, loading test is one of the important links of bridge static load test, and loading test can make prefabricated beams enter the normal working state. The relationship between structural deformation and load is stable, so as to test the design and construction quality of the bridge. [0003] At present, the commonly used loading test methods include direct surcharge method and anchor pile reverse jacking method, the analysis is as follows: [0004] The direct stacking method is the most commonly used method. Generally, steel ingots or concrete blocks are directly stacked on the p...
