Embodiment

[0037] Embodiment: a shock-absorbing post-anchor assembled column base connection device, such as Figure 1-8 As shown, it includes the upper prefabricated part 1, the lower embedded part 2 located in the foundation foundation, and the post-cast concrete 3. After the lower embedded part 2 is installed, the concrete is poured. The surface after pouring is the foundation surface 4, which is the same as The top surface of the foundation foundation is formed by 5 cup foundations; 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 until it is level with the top surface of the foundation foundation Flat concrete structure.

[0038] 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 ...

Abstract

The invention relates to the technical field of connection of fabricated buildings in civil engineering, and particularly discloses a shock-absorbing rear-anchored type fabricated column-foundation connection device. The shock-absorbing rear-anchored type fabricated column-foundation connection device comprises an upper prefabricated part, a lower pre-buried part arranged in a foundation, and post-cast concrete; the upper prefabricated part comprises a prefabricated column and an upper positioning plate, the lower pre-buried part comprises foundation steel bars, a lower positioning plate and anchor bolts, and the upper positioning plate and the lower positioning plate are connected through the anchor bolts; and dampers are connected between the middles of the four sides of the bottom faceof the prefabricated column and the side face of the foundation. According to the shock-absorbing rear-anchored type fabricated column-foundation connection device, the anti-shear ability of the bottom of the concrete prefabricated column is improved, the overall anti-seismic performance is also improved, the safety of a building is ensured, and the shock-absorbing rear-anchored type fabricated column-foundation connection device is suitable for connection of concrete prefabricated columns and foundations of various specifications.

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 a shock-absorbing post-anchor prefabricated column foundation connection device. 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, pull out the wedge and carry out ...
