A kind of internal and external scaffolding and its connecting mechanism

Abstract

The invention discloses an internal and external scaffold and a connecting mechanism thereof. The internal and external scaffold comprises two groups of guide rails and a connecting device, wherein the two groups of guide rails are separately fixedly arranged on the inner side scaffold and the outer side scaffold; the connecting device comprises a connecting base and guide wheel bases fixedly arranged at the two sides of the connecting base; each guide wheel group comprises guide wheels; the guide wheels of the guide wheel groups at the two sides can be arranged in the two groups of the guiderails in a sliding mode; the bottoms of the guide rails are provided with limiting parts for limiting movable positions of the guide wheels; and the limiting parts are detachably arranged on the guiderails. The connecting mechanism for the internal and external scaffold provided by the invention is used for connecting the inner side scaffold to the outer side scaffold, so that stability and strength of the inner side scaffold and the outer side scaffold are improved, and deformation probability of the inner side scaffold is reduced. Besides, the connecting device can slide relative to the guide rails, so that practical climbing height can be ensured to meet lifting stroke height in a climbing process, i.e., the climbing is not blocked by a connecting beam.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an internal and external scaffolding and a connecting mechanism thereof. Background technique [0002] For a building including a lighting shaft, during the building construction process, a scaffold needs to be provided on the outside and inside of the building respectively, that is, including an inner scaffold and an outer scaffold. [0003] In the construction process of existing buildings with lighting wells, the inner scaffolding and outer scaffolding are set independently, and there is no connection between the two. Due to the small layout size of the inner scaffolding, the stability and strength of the inner scaffolding are poor. And it is prone to deformation; due to the existence of the connecting beam, if a connecting device is installed between the inner scaffolding and the outer scaffolding, the connecting device will be hindered by the connecting beam du...

Problems solved by technology

[0003] In the construction process of existing buildings with lighting wells, the inner scaffolding and outer scaffolding are set independently, and there is no connection between the two. Due to the small layout size of the inner scaffolding, the stability and strength of the inner scaffolding are poor. And it is prone to deformation; due to the existence of the connecting beam, if a connecting device is installed between the inner scaffolding and the outer scaffolding, the connecting device will be hindered by the connecting beam during the lifting process, and it is impossible to realize the simultaneous installation of the inner scaffolding and the outer scaffolding. lifting
