Problems solved by technology

[0002] In construction projects, the elevator shaft must be reserved in advance. If it is not well protected, it may cause casualties and bring great safety hazards to the construction. There are many existing protective measures, all of which are based on prevention , did not consider how to reduce the degree of personal injury in the event of an accident. The general practice is to build scaffolding from the bottom up gradually, and fix the formwork or protective net in the compartment

Abstract

The invention discloses an elevator shaft protecting device and relates to an elevator shaft anti-falling energy dissipating device in the building engineering field. The elevator shaft protecting device comprises a rectangular keel framework, a spring mesh is connected to the interior of the rectangular keel framework, two pieces of I-shaped steel are arranged below the spring mesh, an arc-shaped spring steel sheet and a spiral damping spring are arranged between each piece of I-shaped steel and the spring mesh, the open end of each arc-shaped spring steel sheet faces upwards, the two ends of each arc-shaped spring steel sheet are connected with the keel framework through fixed supporting bases respectively, and each fixed supporting base is welded to the keel framework. The spiral damping springs are arranged below the arc-shaped spring steel sheets, the upper ends of the spiral damping springs are connected with the middles of the arc-shaped spring steel sheets through spring clamping sheets, the lower ends of the spiral damping springs are supported on the I-shaped steel through spring bases, and the spring bases are welded to the I-shaped steel. The elevator shaft protecting device can be used for both interlayer protection and bottom layer protection, and the injury degree can be greatly relieved due to energy dissipation design after people fall.

Description

technical field [0001] The invention relates to an elevator shaft anti-fall energy dissipation device in the field of construction engineering. Background technique [0002] In construction projects, the elevator shaft must be reserved in advance. If it is not well protected, it may cause casualties and bring great safety hazards to the construction. There are many existing protective measures, all of which are based on prevention , without considering how to reduce the degree of personal injury in the event of an accident, the general practice is to build scaffolding gradually from the bottom up, and fix the formwork or protective net in the interlayer. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an elevator with a high degree of instrumentation, which can be used as both layer protection and bottom protection, and can greatly reduce the degree of injury through energy dissipation des...
