Arranging method of attached lifting scaffold hoisting/falling-preventing system

Abstract

The invention relates to an arranging method of an attached lifting scaffold hoisting / falling prevention system. In three different structural layers of a building wall, the hoisting system and the falling prevention system are independently and fixedly connected with the wall by respectively using 2-4 connecting bolts arranged in the same straight line. 4 connecting bolts in the middle structural layer are respectively used for connecting a hoisting beam with a falling prevention draw bar, 2 connecting bolts in the upper structural layer are respectively applied to a hoisting draw bar, and 2connecting bolts inn the lower structural layer are applied to a falling prevention beam. The arranging method changes the traditional mode that the hoisting system and the falling prevention system can only be arranged in the two structural layers, so that only one row of connecting bolts (pre-embedded holes) needs to be arranged in each building structural layer, and the use amount of the connecting bolts (pre-embedded connecting holes) is greatly reduced. Especially, the invention solves the problem that the connecting bolts (pre-embedded connecting holes) are difficult to be arranged in the traditional two-row mode because the arranging space of the connecting bolts (pre-embedded connecting holes) is small and narrow due to more and more complex and variable building shapes. Thus, thearranging method benefits construction operation and increases construction safety.

Description

technical field [0001] The invention relates to a setting method for a lifting / falling prevention system attached to a lifting scaffold in building construction. Background technique [0002] Attached lifting scaffolding in building construction is a special lifting construction machine with vertical lifting movement / transportation function. Lifting operation, and the suspended movable overall structure scaffolding with a certain height itself, is driven by the lifting equipment (mostly lifting mechanical equipment) scattered throughout the building to carry out high-altitude lifting / lowering construction. [0003] According to JGJ202-2010 "Safety Technical Specifications for Building Construction Tool Scaffolding", in order to ensure construction safety, the lifting system and the anti-falling system attached to the lifting scaffold must be set up independently of each other and connected to the building wall respectively, and it is not allowed to share the same Set of sys...

AI Technical Summary

Problems solved by technology

Since the attached lifting scaffold can usually only be connected with the external convex structure such as the balcony outside the building, and the diversification and complexity of the external shape design of the building, there are often many external structures on the wall of the building that can be connected by the attached lifting scaffolding. When the height of the convex part is less than 400mm, it will be very difficult to set the embedded holes and connecting bolts in the traditional upper and lower two layers in the smaller remaining height after removing the thickness of the concrete protective layer and the position of the steel bar

Even if it can sometimes be set up in the way of upper and lower floors, it is easy to have hanging beams in the air and / or poor force, which not only affects the construction progress, but also poses unsafe hazards

In particular, the part of the wall of some buildings that can be connected by the attached lifting scaffold will have convex and / or concave parts that appear at any time (such as a balcony with a split-level design, etc.), which adds the traditional method of installing the attached lifting scaffold and its The difficulty of related systems also increases unsafe factors and hidden dangers
