A kind of tooling and its construction method with double tracks for jacking and accumulative sliding

Abstract

The invention discloses a tool provided with double tracks to conduct pushing, accumulating and slipping and a construction method thereof. The tool comprises a pushing, accumulating and slipping joint, a slipping structure main body position locating joint and a steel strand pulling and arranging joint. The pushing, accumulating and slipping joint comprises a V-shaped column hemisphere supporting seat, compound section shoulder pole beams, steel slipping boots and a pushing device. The slipping structure main body position locating joint comprises upper brackets, jacks and lower brackets. The construction methods comprises the steps that (a) the lower brackets are manufactured and mounted; (b) the pushing, accumulating and slipping joint is manufactured and mounted; (c) the upper brackets are manufactured and mounted; (d) the pushing, accumulating and slipping joint is welded to a slipping structure main body; (e) prestressed steel strands are tensioned; (f) the pushing device and the steel slipping boots are mounted; (g) pushing and slipping construction is conducted; and (h) the slipping structure main body is located. According to the tool and the construction method thereof, the problems that the deflection of a single beam and a single track is large, the force of a slipping structure is uneven, and slipping is difficult are solved, and meanwhile the problem that the slipping structure main body is difficult to locate after slipping is completed is solved.

Description

technical field [0001] The invention belongs to the technical field of steel structure installation, and in particular relates to a tooling for pushing and accumulating sliding with double tracks and a construction method thereof. Background technique [0002] The open-air raw material storage yards used by enterprises such as thermal power, cement industry, and steel smelting will not only cause raw material loss due to raw material dust scattering, but also cause environmental pollution due to raw material dust flying. With the strengthening of awareness of environmental protection, energy saving, and material saving, enterprises such as thermal power energy, cement industry, and steel smelting are vigorously building, rebuilding, and expanding closed raw material storage closed sites. From the comprehensive consideration of the use function, economy and other aspects, the super long-span arched cylindrical reticulated shell structure is mainly selected for the closed fiel...
