Description

Technical Field

[0001] This utility model belongs to the field of support structure technology, and in particular relates to a prefabricated reinforced confined masonry energy dissipation device support structure. Background Technology

[0002] Earthquakes are sudden and destructive natural disasters. According to Article 16 of the "Regulations on Seismic Management of Construction Projects," newly constructed schools, kindergartens, hospitals, elderly care institutions, children's welfare institutions, emergency command centers, emergency shelters, and radio and television stations located in high-intensity seismic fortification areas or key earthquake monitoring and defense zones should adopt seismic isolation and damping technologies in accordance with relevant national regulations to ensure they can meet normal usage requirements during earthquakes of the designated seismic fortification level in the region. According to Article 21 of the same regulations, when seismic reinforcement is carried out on existing buildings such as schools, kindergartens, hospitals, elderly care institutions, children's welfare institutions, emergency command centers, emergency shelters, and radio and television stations located in high-intensity seismic fortification areas or key earthquake monitoring and defense zones, seismic isolation and damping technologies should be adopted after thorough evaluation to ensure their seismic performance meets mandatory seismic fortification standards.

[0003] Adding energy dissipation devices to buildings in the "two zones and eight categories" (schools, hospitals, nursing homes, etc.) can effectively reduce the impact of seismic forces on the main structure. Energy dissipation devices typically consist of piers connected to the main structure and energy dissipators between the piers. Energy dissipators absorb or dissipate seismic energy through elasto-plastic deformation generated by reciprocating motion, thereby reducing the seismic response of the main structure to a certain extent.

[0004] In practical engineering, ensuring the reliability of energy dissipation devices is crucial for them to function effectively. The connections within these devices are particularly important and therefore require special reinforcement. Currently, the common construction method for energy dissipation device supports is to pour concrete on-site and simultaneously install embedded parts on the supports. The energy dissipator is then connected to these embedded parts, such as... Figure 1 As shown.

[0005] The following are the main problems with on-site casting of pier supports:

[0006] 1. The construction is complicated, requiring on-site formwork, especially the formwork and concrete pouring of the upper support piers.

[0007] 2. Embedded parts need to be installed before the concrete of the support pier is poured, which is prone to inaccurate positioning and further increases the complexity of on-site pouring.

[0008] 3. The supports are often 1.5m to 2m long, occupying a lot of the brick wall space, making it difficult to meet the increasing requirements of high assembly rates in construction. Utility Model Content
