Device for anti-falling partition in elevator shaft

Abstract

The invention provides a device for an anti-falling partition in an elevator shaft, and relates to a device for constructing an anti-falling partition. The device for the anti-falling partition in the elevator shaft comprises a partition framework, a partition plate and a safety net hanging device, wherein the partition plate is arranged on the partition framework; the safety net hanging device is arranged on the partition plate; the partition framework comprises two main beams, a plurality of secondary beams, a plurality of retractable secondary beams and two boundary beams; the secondary beams which are parallel to one another are connected to the two main beams; the two boundary beams are respectively arranged on the outer sides of the two main beams; each boundary beam is connected with a row of retractable secondary beams which inwards extend into through holes of the secondary beams; front ends of the two main beams are respectively connected with retractable beam heads I; an end surface of the front end of each retractable beam head I is arranged into a cutting corner of which the lower side is inclined rearwards; lower sides of the rear ends of the two main beams are also respectively connected with brackets which can be abutted to a shaft wall on the lower side of a door opening of the elevator shaft; the angle of the rearwards inclined lower side of each bracket is equal to the angle of the rearwards inclined cutting corner at the front end of the corresponding retractable beam head; the partition plate is arranged above the secondary beams; and the safety net hanging device is connected to the partition framework.

Description

technical field [0001] The invention relates to a device for anti-falling partitions in construction, in particular to a device for anti-falling partitions in elevator shafts. Background technique [0002] At present, high-rise buildings and super high-rise buildings are becoming more and more common, and the opening of elevator shafts has become one of the biggest safety hazards. 3.13.3.5 of the current specification "Building Construction Safety Inspection Standard" JGJ59-2011 clearly stipulates the protection in the elevator shaft: before the elevator is installed, safety flat net protection should be installed every two floors and not greater than 10m in the elevator shaft. The conventional method in the prior art is: pre-embed the wall-penetrating casing on the side of the elevator door opening and in the opposite shear wall, and insert the steel pipe into the pre-embedded casing to build a vertical and horizontal well-shaped horizontal partition base. closed. A safet...

Problems solved by technology

This conventional method has the following disadvantages: 1. Pre-embedded casing is time-consuming and labor-intensive, and may be buried during construction, and the pre-embedded position is not on the same level; 2. It is dangerous to seal the reserved hole and waste materials; 3. The size of elevator shafts varies in different projects, and the steel pipes cannot be effectively reused
