Using method of slidable supporting system suitable for vertical narrow space

Abstract

The invention provides a using method of a slidable supporting system suitable for a vertical narrow space. The using method comprises the steps that a ring well track, a plurality of telescopic supporting assemblies and two driving transmission parts are adopted, the ring well track is installed on the inner wall of the vertical narrow space, and the ring well track is of a rectangular structureformed by connecting four track sections; the two ends of the telescopic supporting assemblies are correspondingly arranged on one pair of opposite track sections of the ring well track through sliding pieces; and the telescopic supporting assemblies tightly abut against the ring well track to tightly abut against the two opposite inner walls of the vertical narrow space, the stress of the telescopic supporting assemblies is more uniform, and the influence of peripheral foundation pit construction on the vertical narrow space is reduced. The sliding pieces at the two ends of the telescopic supporting assemblies can move along the ring well track under the action of the corresponding driving transmission parts, so that electromechanical pipelines in the vertical narrow space are avoided. The construction and installation steps of the supporting system in the vertical narrow space are simplified, and the operability and safety of construction are improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a method for using a slidable support system suitable for vertically narrow spaces. Background technique [0002] Vertically narrow spaces generally play the role of fire-fighting and smoke exhaust, air-conditioning and ventilation in buildings, and some vertically narrow spaces also need to lay pipelines. [0003] When underground engineering such as foundation excavation is carried out around the vertical narrow space, it may have an impact on the vertical narrow space, which may lead to the collapse of the vertical narrow space, so it is necessary to support and reinforce the vertical narrow space. [0004] At present, to support the vertical narrow space, the commonly used reinforcement form is to set up steel pipes or I-beams in the vertical narrow space for support. This method, on the one hand, often requires a large construction space, resulting ...

Problems solved by technology

[0004] At present, to support the vertical narrow space, the commonly used reinforcement form is to set up steel pipes or I-beams in the vertical narrow space for support. This method, on the one hand, often requires a large construction space, resulting in It is difficult to install in a narrow space; on the other hand, the establishment of supporting devices and the obstruction of the original pipeline greatly increase the difficulty of construction; on the other hand, the steel pipe or I-beam directly contacts the wall of the vertical narrow space, and the contact area is small , when the force in the vertical narrow space is too large, it is likely to cause damage to the wall of the vertical narrow space by the support device
