A slidable support system for vertically narrow spaces

Abstract

The invention provides a slidable support system suitable for vertically narrow spaces, which adopts ring well rails, several telescopic support components and two drive transmission parts. The support assembly tightens the two opposite inner walls of the vertical narrow space by tightening the ring well track, which optimizes the stress on the walls of the vertical narrow space during support, makes the force more uniform, and greatly reduces the construction of the peripheral foundation pit. The impact on the vertical narrow space improves the safety factor of the vertical narrow space. The sliding parts at both ends of the telescopic support assembly can move along the ring well track under the action of the corresponding driving transmission parts, so that the telescopic support assembly can realize Horizontal movement, so that pipelines can be avoided, so that multi-professional construction personnel can work synchronously, improving construction efficiency. In addition, the invention simplifies the construction and installation steps of the support system in the vertical narrow space, and greatly improves the convenience of construction.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to 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 in It is difficult...

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
