Structure synchronous unloading device and construction method thereof

Abstract

The invention discloses a structure synchronous unloading device and a construction method thereof. The structure synchronous unloading device comprises an upper structure column, a lower structure column, a structure beam, a gap, a bracket, a temporary fixing device and a synchronous unloading control system, wherein the gap is formed between the upper structure column and the lower structure column; the bracket is welded on the upper structure column; the upper structure column and the lower structure column are fixed through the temporary fixing device; a cushion block, an inclined cushion block, an adjusting cushion block, a hydraulic jack and a U-shaped cushion block are respectively placed on the structure beam from bottom to top; and the synchronous unloading control system comprises a hydraulic power unit, a synchronous control system and a hydraulic line. The construction method comprises the following steps: determining the size of the gap; temporarily fixing through the temporary fixing device; placing the cushion block and the like; unloading; installing the hydraulic power unit; dismantling the U-shaped cushion block; unloading in a graded way; and welding the upper structure column and the lower structure column. The structure synchronous unloading device is high in safety, low in low, little in pollution and convenient and fast in operation, a support jig frame is not used as a force transfer structure, and the long-time stress of a jack piston is avoided.

Description

technical field [0001] The invention relates to an unloading device and a construction method thereof, in particular to a structure synchronous unloading device and a construction method thereof. Background technique [0002] As people's requirements for building functions are getting higher and higher, long-span plane (space) and some upside-down system structures are favored. In order to meet the construction needs of large-span and upside-down system structures, temporary structures need to be adopted before the structure is installed or meets the design requirements. Unloading device, at present, the most commonly used unloading methods are mechanical gear (electrohydraulic) jack, supporting tire frame and sandbox, etc., but the jack unloading technology has problems of poor work performance, high unloading cost, and great influence by human factors. Mechanical gear (electro-hydraulic) jacks that are stressed for a long time in a long project are prone to damage, oil lea...

[0002] As people's requirements for building functions are getting higher and higher, long-span plane (space) and some upside-down system structures are favored. In order to meet the construction needs of large-span and upside-down system structures, temporary structures need to be adopted before the structure is installed or meets the design requirements. Unloading device, at present, the most commonly used unloading methods are mechanical gear (electrohydraulic) jack, supporting tire frame and sandbox, etc., but the jack unloading technology has problems of poor work performance, high unloading cost, and great influence by human factors. Mechanical gear (electro-hydraulic) jacks that are stressed for a long time in a long project are prone to damage, oil leakage, etc., which not only pollute the environment but also affect the safety of the entire structure; the unloading technology of the supporting tire frame is only suitable for structures with small load and deformation Unloading, production, installation, and dismantling costs are high, which affects the structural construction of the tire frame, and the direct cutting and unloading method is likely to cause short-term stress release, which has a high risk of unloading and affects structural safety; sandbox unloading requires more support points. There is also a lot of manpower invested; and the support tire frame + jack (sandbox) unloading technology also has the problem of jack (sandbox) unloading technology. In addition, the above methods cannot realize synchronous unloading, and the safety performance is low.
