Hinge joint of additional elevator shaft and original structure through limiting fixing assembly and construction method

Abstract

The invention relates to hinge joint of an additional elevator shaft and an original structure through a limiting fixing assembly and a construction method. An original structure wall body, an additional elevator steel structure shaft, a limiting clamping piece and two limiting fins are involved; the limiting clamping piece and a limiting clamping piece back plate are fixed through welding; the limiting clamping piece back plate and the original structure wall body are fixed through wall penetrating bolts; the two limiting fins are respectively welded on a limiting fin back plate; the limitingfin back plate and the additional elevator steel structure shaft are fixed in a welded mode, and before the limiting fins and the additional elevator steel structure shaft are welded, the limiting fins and the limiting fin back plate are welded; and the limiting clamping piece is connected with the two limiting fins in a mode that the limiting clamping piece is contained by the two limiting fins.When an additional elevator structure sinks, the limiting clamping piece slides in the two limiting fins, so that the whole structure realizes that horizontal loads are jointly borne and vertical loads are borne by the additional elevator steel structure shaft in a force transmission mode, and cooperative work is achieved.

Description

technical field [0001] The invention relates to a hinge connection between an additional elevator shaft and an original structure using a limit fixing component and a construction method thereof, belonging to the technical field of comprehensive transformation of existing buildings. Background technique [0002] With the gradual improvement of urban living standards, there are more and more elevator projects in existing buildings. This involves the connection between the additional elevator structure and the original building structure. However, in engineering practice, the problem of interconnection between the original building structure and the external elevator structure has not been well resolved, and the problem that the new and old buildings can jointly bear the horizontal load cannot be fully achieved. In order to solve these problems, the present invention focuses on solving the problem that the elevator shaft of the existing building is connected with the original...
