Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a bottom formwork reinforcement device for an upper pier of a seismic isolation bearing and a construction method thereof. Background Art

[0002] Traditional seismic design is committed to ensuring that the structure itself has sufficient strength, rigidity and ductility, so that the building can be "not damaged by small earthquakes, repairable by medium earthquakes, and not collapsed by large earthquakes", thereby achieving the purpose of reducing earthquake disasters. However, with the rapid development of social economy, a large number of buildings of different natures and types have sprung up like mushrooms after a rain. This not only brings technical challenges to seismic isolation design, but also to seismic isolation construction under complex structures. Seismic isolation bearings are the most traditional shock absorption method. The formwork support of the seismic isolation bearing piers of complex structures is often an insufficient consideration during the formwork construction process. General steel pipe brackets are difficult to support the upper and lower piers of the seismic isolation bearing. Although the use of wooden squares for support is more convenient, the weight of the upper pier concrete is often large, and the wooden square support can easily cause the bottom formwork to deform, thus affecting the safety of the seismic isolation structure.

[0036] In this embodiment, the notch of the slide slot 110 extends oppositely to form an anti-slip lip plate. The two opposite sides of the slider form a limit block. The limit block abuts against the inner side of the anti-slip lip plate. The limit block is arranged on the side of the end face of the slider away from the support plate, and the limit block and the slider are T-shaped.

[0037] In some embodiments, the width of the slide groove 110 gradually decreases from the bottom of the slide groove 110 to the notch of the slide groove 110. The cross section of the slider is adapted to the cross section of the slide groove 110.

[0038] In this embodiment, the support assembly 2 includes two blocks 21 and a length-adjustable support rod 22. The support rod 22 is connected to the two blocks 21. The support assembly 2 is supported between opposite sides of the support plates 11 of the two support assemblies 1.
