Embodiment

[0053] Example: Combine Figure 1-8 As shown, this embodiment includes an upper prefabricated part 1, a lower embedded part 2 located in the foundation foundation and a post-cast concrete 3. After the lower embedded part 2 is installed, concrete is poured, and the surface after pouring is the foundation surface 4 , which forms a cup foundation with the top surface of the foundation foundation; then the upper prefabricated part 1 and the lower embedded part 2 are connected, and the post-cast concrete 3 is finally poured with fine stone concrete of a higher strength level to the foundation foundation Concrete structure with flush top.

[0054] The upper prefabricated part 1 includes a prefabricated column 11 and an upper positioning plate 13. The prefabricated column 11 is a reinforced concrete cuboid structure, and its bottom four corners are respectively fixed with corner protectors 12. The corner protectors 12 have a thickness of 3mm, a width of 50mm, and a height of 30mm. T...

Abstract

The invention relates to the technical field of connection of prefabricated buildings in the discipline of civil engineering, and specifically discloses an energy-consuming bolt-type connection method for connecting concrete prefabricated columns and foundations. The specific steps are as follows: (1) prefabrication of upper prefabricated parts; (2) ) the installation of the lower embedded parts; (3) foundation template support and concrete pouring and maintenance; (4) prefabricated column installation pre-construction preparation; (5) precast column and foundation connection; (6) damper connection; ( 7) The pouring and maintenance of post-cast concrete at the joints. The invention not only improves the shear resistance of the bottom of the concrete prefabricated column, but also improves the overall anti-seismic performance, ensures the safety of the building, and is suitable for the connection between the concrete prefabricated columns of various specifications and the foundation.

Description

technical field [0001] The invention relates to the technical field of connection of prefabricated buildings in the discipline of civil engineering, in particular to an energy-consuming bolt connection method used for connecting concrete prefabricated columns and foundations. Background technique [0002] In recent years, with the rapid development of my country's infrastructure construction, prefabricated buildings have been vigorously promoted by the state and the government, and node connections in prefabricated buildings are particularly important. The construction technology of the prefabricated concrete column foundation connection mainly adopts the following two connection methods: one is the cast-in-place connection, the foundation is made into a cup shape, and after the prefabricated column is hoisted and corrected, the concrete is first poured into the temporary fixed column When the concrete strength reaches more than 25% of the design strength standard value, pul...
