When installing the elevator, the elevator shaft frame needs to be installed in advance. It is mainly composed of columns and beams, and most of them are fixed by welding. Welding has certain difficulties. Now most of them use assembled elevator shaft frames for installation and use.

[0003] There are many types of such elevator shaft frames on the market today, which can basically meet people's usage needs, but there are still certain problems. The elevator shaft frames are generally not convenient for convenient assembly and use when in use. For example, Chinese patent publication number CN218088456U discloses an assembled elevator shaft frame, including an east side support and a south side support, the east side support is provided with a south side support outside, the south side support is provided with a west side support outside, and the west side support is provided with a north side support outside.

[0004] Although the elevator shaft frame realizes the convenient assembly and use of the assembled elevator shaft frame, no supporting structure is set between the support arms, resulting in a large supporting pressure of the support arms when the shaft frame is used for a long time, increasing the risk of the shaft frame shaking. For this reason, we propose an assembled elevator shaft frame to solve the above problem. Utility Model Content
