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 an assembly type building in the civil engineering subject, and particularly discloses an energy consuming type bolt type connecting method used for concrete precast column and foundation connection. The method comprises the specific steps of firstly, prefabrication of an upper prefabricated part; secondly, mounting of a lower embeddedpart; thirdly, foundation template bracing and concrete pouring and curing; fourthly, preparation before precast column mounting construction; fifthly, precast column and foundation connection; sixthly, damper connection; and seventhly, pouring and curing of post-cast concrete on a connecting joint. Anti-shear capacity of the bottom of concrete precast columns can be improved, the whole anti-vibration property is improved, the safety of a building is ensured, and the method is suitable for connection of the concrete precast columns of various specifications and a 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...
