Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a prefabricated elevator column base connection structure. Background Technology

[0002] In the construction industry, with the continuous advancement of urbanization, elevators in older residential buildings need to be added to facilitate convenient travel. Prefabricated elevators, as a key component, directly affect the functionality and quality of the entire building through their performance and safety. The elevator column base connection structure, as a fundamental component of prefabricated elevators, effectively transfers loads, reduces damage caused by vibration and impact, and thus improves the elevator's service life and operational reliability.

[0003] In related technologies, to improve installation convenience and prevent disturbance to residents, factory prefabrication is adopted. The connection column base nodes between the elevator steel structure and the ground foundation are generally fixed in the early stage by ribs and bolts. The bolts fix the plate to the ground foundation, and then the steel column and the ribs set around the steel plate are fixed by welding.

[0004] However, the above-mentioned technologies have drawbacks: they require high welding skills from operators and may cause displacement of the connection, affecting the verticality of the steel column relative to the ground. On the other hand, the ribs set around the perimeter are inconvenient to install and are prone to positioning errors. Therefore, a column base connection structure that can solve the above problems is needed. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a prefabricated elevator column base connection structure.

The rib plate is configured to cooperate with the slot. The limiting sleeve has a limiting hole corresponding to the circular through hole.

[0009] An embedded part is fixedly connected to the end of the base plate away from the steel column.

With the help of the rib plate of the fastener and the limiting hole on the limiting sleeve, the steel column and the fastener can be effectively positioned and connected. The base plate of the fastener, the limiting sleeve and the rib plate cooperate with each other to enhance the stability of the structure. The embedded part is fixedly connected to the end of the base plate away from the steel column, which can firmly fix the entire connection structure on the foundation and improve the overall stability and reliability of the prefabricated elevator column foot connection structure.

[0011] Preferably, the limiting sleeve is located inside the steel column and fits against the inner wall of the steel column, and the limiting holes are located around the limiting sleeve and arranged in an array.

[0012] By adopting the above technical solution, the limiting sleeve is located inside the steel column and fits against the inner wall, which can enhance the tightness and stability of the connection between the steel column and the fastener; the limiting holes are arrayed around the limiting sleeve, which facilitates accurate positioning and firm connection.

[0014] By adopting the above technical solution, two ribs connected in a cross shape and symmetrically arranged around the central axis of the steel column enhance the stability and load-bearing capacity of the structure.

This design allows the anchor bolt 321 to be better fixed in the foundation, increasing the reliability of the connection. The vertical portion 3211 is rod-shaped and includes several spaced-apart reinforcing members 3213. The reinforcing members 3213 are branch-shaped with upward-facing openings, further enhancing the anchoring capacity of the anchor bolt 321. The anchor bolts 321 are typically made of high-strength steel to ensure they can withstand large loads.

[0044] refer to Figure 1 and Figure 4This application embodiment also includes a support component 4, which is fixedly installed between adjacent steel columns 1. The side closest to the original wall surface does not have a support component 4 to facilitate the subsequent addition of structures such as connecting corridors. Specifically, the support component 4 includes an mounting plate 41 and a diagonal support 42.
