A suspended material platform for scaffolding with a winch puller adjustment device

Abstract

The invention relates to a scaffold cantilever material platform with sheave tensioning adjustment devices. The scaffold cantilever material platform comprises a material platform plate. The two sides of the material platform plate are each provided with one material platform longitudinal beam. Each material platform longitudinal beam is connected with the surface of a building floor through a U-type anchoring bolt fastening device. Two sets of hoisting rings are arranged in the symmetrical positions of the two sides of the material platform plate correspondingly. Each set of hoisting rings includes a safety hoisting ring, a tensioning hoisting ring and a material platform plate hoisting ring, wherein the safety hoisting ring is connected with a safety steel wire rope, the tensioning hoisting ring is connected with a tensioning steel wire rope, and the material platform plate hoisting ring is connected with a hoisting steel wire rope. The two sides of the upper portion of the material platform plate are each provided with one sheave tensioning adjustment device. The safety steel wire rope and the tensioning steel wire rope on the same side are jointly connected with the sheave tensioning adjustment device on the corresponding side. The tensioning force of the four steel wire ropes of the cantilever material platform in the invention is large, and safety and reliability are realized. The scaffold cantilever material platform can be repeatedly dismounted and mounted for use many times, is convenient to install, saves labor and materials when manufactured, and has remarkable economical benefits.

Description

technical field [0001] The invention relates to the technical field of construction auxiliary equipment, in particular to a scaffold overhanging table with a pulley tie adjustment device. Background technique [0002] The existing building cantilever table is generally installed by a wire rope pulling device. The wire rope pulling device usually adopts the method of pre-embedding the steel pipe, the method of lowering the diagonal support and the method of pulling the wire rope up, or the method of pre-embedding the anchoring ring, but they are common. The following problems: (1) The construction operation process is cumbersome, and some methods require the cooperation of welding and cutting types to complete; (2) Most of the existing pre-embedded construction methods can only achieve the force of one steel wire rope due to the limitation of the pre-embedded position and angle. The force value of the wall and the steel wire rope is small; (3) the way of pre-embedding steel p...

AI Technical Summary

Problems solved by technology

[0002] Existing building cantilever material platforms are generally installed by wire rope lifting devices, which usually adopt the method of pre-embedded steel pipes, the method of lower support and diagonal support to pull up the wire rope, or the method of pre-embedded anchor rings, but they are common. The following problems: (1) The construction operation process is cumbersome, and some methods require the cooperation of welding and cutting workers to complete; (2) Most of the existing pre-embedded construction methods can only reach the force of one steel wire rope due to the restrictions on the pre-embedded position and angle. The force value of the wall and the steel wire rope is small; (3) the method of pre-embedding steel pipes in the prior art is likely to cause wall maintenance holes, and there are hidden dangers of swelling and leakage; (4) pre-embedding steel pipes will reduce the wall (beam) force. Strength; (5) The pre-embedded materials are not recyclable, and steel pipes and steel bars are embedded in the wall, which is difficult to recycle
