Abstract

The invention relates to a device for integrally jacking a roof of a single-layer industrial factory building. The device is characterized by comprising three parts, namely a jacking device, a vertical force transfer device and a synchronous control device, wherein the vertical force transfer device is arranged on the ground of the factory building; and the jacking device is fixed above the vertical force transfer device and is connected with the synchronous control system. The construction method comprises the following steps of: enabling an upper section of an adjustable steel support column to be positioned in a freely-retractable state; fixing an inverted T-shaped counterforce cross beam, starting the synchronous control system and jacking a conventional shot-travel hydraulic jack to one travel height; fixing the upper section of the adjustable steel support column to enable the inverted T-shaped counterforce cross beam to be positioned in a freely-retractable state, starting the synchronous control system, retracting the jack and upwards hoisting the inverted T-shaped counterforce cross beam to be a travel height; and repeating the step (1) and the step (2) until an original roof frame beam is jacked to the designed elevation and realizing integral jacking of the roof of the single-layer industrial factory building. In the jacking process, an inserting pin of the adjustable steel column and an inserting pin at the end part of the counterforce cross beam are extracted out or inserted into conveniently and quickly by just arranging constructors according to the sequenceof jacking cycle.

Description

technical field [0001] The invention relates to a device and construction method for integrally lifting the roof of a single-story industrial factory, in particular to a method of using conventional short-stroke hydraulic jacks and adjustable steel pillars, combined with synchronous control technology, without damaging the single-layer In the case of an industrial plant roof system, a device and a method for realizing integral jacking of the roof structure. It belongs to the technical field of civil engineering construction. Background technique [0002] With the continuous development of my country's economic construction and the rapid rise of large-scale industrial projects, the interior space of some single-storey industrial plants built earlier can no longer meet the needs of modern technology or production, but demolition and reconstruction will not only take up a long production time, Moreover, it will bring repeated investment in the economy, resulting in a great wast...
