A sliding lifting bracket and its construction method

Abstract

The invention provides a slippage type hoisting bracket and a construction method thereof, and belongs to the technical field of building engineering. The slippage type hoisting bracket solves the technical problem that an existing bracket is low in construction efficiency and large in potential safety hazard. According to the technical scheme, the slippage type hoisting bracket comprises a fixed support arranged around a pile hole, a movable support vertically arranged, movably connected with the fixed support, and capable of horizontally moving on the fixed support, and a transferring box movably connected with the movable support, capable of moving in the vertical direction and used for receiving a soil body in the pile hole; and the transferring box can transfer the soil body in the pile hole out to be far away from the pile hole through vertical movement of the transferring box and horizontal movement of the movable support. The slippage type hoisting bracket has the beneficial effects of being simple in structure, small in floor area, convenient to erect and very suitable for operation in small space; and the structure is relatively convenient to use, operators are fewer, manpower is saved, and meanwhile the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and relates to a lifting bracket and a construction method thereof, in particular to a sliding type lifting bracket and a construction method thereof which can be used for vertical transportation in the construction process of manual hole-digging piles. Background technique [0002] As an ancient construction technology of pile foundation engineering, artificial excavated pile has the advantages of high pile quality and large bearing capacity, and plays an important role in some heavy equipment foundations and pile foundation projects with large loads. However, manual hole-digging piles are manual and semi-mechanized operations. The underground work space is small, labor intensity is high, construction efficiency is low, and safety hazards are large, which affects the application of manual hole-digging piles. [0003] However, during the excavation and construction of manual excav...

AI Technical Summary

Problems solved by technology

In the construction of manual excavated piles, due to the limited construction space, the machinery cannot be fully used, and there are excavators working at the bottom of the hole, so the safety and convenience of the lifting device above the hole is particularly important

[0004] After research and investigation, it was found that the existing processing method on the construction site is to use a simple herringbone bracket to support above the hole position, and to hang the pulley, and to excavate the soil in the hole by manually pulling and lifting the hanging basket. This method of construction The efficiency is low, and it is easy to fall from a high altitude due to the unstable swing during artificial lifting and traction, causing personal injury to the people below
