Problems solved by technology

However, it takes a certain amount of time to dismantle and erect scaffolding, which will bring great potential safety hazards to construction workers during this period of time. At the same time, the technical requirements for erecting personnel are high, and the time for dismantling and erecting is long. The structure of scaffolding is complex and inefficient. The scaffolding is prone to shaking and has a low safety factor

Abstract

The invention discloses a rapid elevator shaft hard protection device and a construction technology thereof. The rapid elevator shaft hard protection device comprises a bottom plate, wherein a counterweight device and a control device are arranged on the bottom plate, a bearing plate is hinged to one end of the bottom plate, a first supporting plate is fixedly arranged at the end, away from the bottom plate, of the bearing plate, a fixing plate is fixedly arranged at the end, close to the bearing plate, of the bottom plate, the fixing plate is perpendicular to the bottom plate, and two first electric push rods are fixedly arranged on the outer wall of the fixing plate. The rapid elevator shaft hard protection device has the beneficial effects that a protection plate can be conveniently and quickly mounted and conveniently dismounted, the technical requirement for erecting personnel is low, the dismounting and erecting time is short, the structure stability is good, the safety is high, the device can adapt to buildings with different floor distances, electric control is adopted, the labor intensity and the labor amount of workers can be greatly increased, and the personal safety of the workers can be greatly protected.

Description

technical field [0001] The invention relates to the field of hard protection devices for elevator shafts, in particular to a quick hard protection device for elevator shafts and a construction process thereof. Background technique [0002] In recent years, with the rapid development of urban and rural construction in our country, a large number of high-rise buildings have emerged, which has brought about economic development and also led to frequent safety accidents. The construction authorities in various places have paid more and more attention to the safety management of construction sites. [0003] At the construction site of the housing construction project, the entrance of the elevator shaft is the place where safety accidents are most likely to occur. In order to reduce the occurrence of casualties, the protection of the opening of the elevator shaft is particularly important. When the floor is poured from bottom to top, the opening of the elevator shaft becomes an im...
