Synchronous construction platform and method for ultrahigh chimney cylinder and lining

Abstract

The invention provides a synchronous construction platform and method for an ultrahigh chimney barrel and a lining. The construction platform comprises a chassis, a transition platform and a top platform; the center of the chassis is fixedly connected to a supporting frame extending in the vertical direction, and the supporting frame is provided with a first climbing mechanism and a second climbing mechanism which are distributed up and down at an interval; the transition platform and the top platform are both connected to the supporting frame in an up-down sliding and sleeving mode and connected to the first climbing mechanism and the second climbing mechanism respectively; and a plurality of open frames used for fixing an inner formwork and an outer formwork in a matched mode are distributed on a bottom frame of the top platform in a circumferential array mode. According to the synchronous construction platform for the ultrahigh chimney barrel and the lining, the chassis and the transition platform can be driven by the first climbing mechanism to climb upwards in sequence, so that the chassis and the transition platform are lapped and fixed on each layer of annular bracket step by step, overall ascending is realized, a climbing supporting rod is not needed, construction consumables can be reduced, the lining is convenient to build, and the whole body can settle to the ground after construction reaches the top.

Description

technical field [0001] The invention belongs to the technical field of ultra-high chimney construction, and in particular relates to a synchronous construction platform and method for an ultra-high chimney barrel and lining. Background technique [0002] Buildings such as chimneys, prilling towers, and silos are common buildings in the chemical industry. During the construction process, climbing platforms are required to carry out operations, and at the same time cooperate with lifting devices to lift materials to the climbing platforms. At present, with the increasing environmental protection requirements at home and abroad, the design height of chimneys used in chemical industry is also increasing. Ultra-high chimneys over 150 meters are not uncommon. In the field of construction, the common tubular building construction The techniques include slipform construction, overturning or inverted formwork construction, pulling formwork construction, etc. Among them, the overturni...
