Technology for dismounting beret pieces of cast-in-situ beam bottoms

Abstract

The invention discloses a technology for dismounting beret pieces of cast-in-situ beam bottoms. A lifting frame is provided with a lifting motor; a bridge is provided with vent holes; a crossbeam on the lower surface of the bridge is provided with a through hole through gas cutting; the diameter of the through hole in the crossbeam is limited between 28 to 30 mm; a vertical channel steel which is vertical to the crossbeam is installed above one end of the crossbeam through bolts; the crossbeam is provided with slidable electric hoists; a crashproof guardrail is installed between the vertical channel steel and a flange plate at one side of the bridge; a bridge support is cast under the bridge; a bottom of the bridge support is provided with a beret piece. By means of the technology of the invention, the construction process is reduced and the construction is safer, therefore greatly increasing work efficiency and reducing the detention time of beret pieces at beam bottoms; the construction period is shortened and the construction process is more stable and reliable; the cost for man power can rent of beret pieces are saved; the technology is worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of demolition of berets, in particular to the demolition of berets of cast-in-place beam bottoms. Background technique [0002] As an agricultural country with a large population, my country's per capita area is decreasing with the pollution of the environment. In order to solve the problem of the land where people live and the traffic problems in some special places, various places have to be included in the construction site of civil engineering. , Civil engineering includes the planning, construction and maintenance of all infrastructure related to water, soil and culture. Common civil works projects at present include housing, roads, water works, drainage works, flood control works and traffic, etc. In the past, all non-military civil engineering projects were classified into this category, but as engineering science becomes more and more extensive, many contents that originally belonged to the scope of ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides the removal technology of the cast-in-place girder bottom Bailey sheet, which solves the problem that, for bridge structures, after the beam in-situ casting is completed, in most cases, the bridge bottom cannot support the hoisting equipment, or There is insufficient clearance at the bottom, which increases the difficulty of construction during demolition, and slows down the construction speed and work efficiency to a certain extent.
