Embodiment Construction

[0027] A low-altitude modular assembly integral sliding form lifting method for a steel structure on the roof of a concrete silo, comprising the following steps:

[0028] (1) Assembling the inclined beam unit

[0029] (1) Installation of connection plates and purlin support plates: The I-beams are welded to the connection plates according to the drawing requirements, and are respectively installed at the same positions on both sides of the webs of the I-beams, and the I-beams are divided into 3 equal parts on average; the purlin support plates Upright welded on the I-beam upper wing plate, and the middle and lower part of each support plate is set with triangular steel support; the purlin support plate is evenly set according to the requirements of the drawing;

[0030] (2) Welding of diagonally braced steel pipes and purlins

[0031] Arrange the connecting plates on the beam according to the spacing of the drawing, spot weld the horizontal steel pipe supports between the con...

Abstract

The invention discloses a method for lifting whole steel structure to the top of a concrete cabin through a slip form and low-altitude modular assembly. The method comprises the steps of assembling oblique beam units, assembling steel ring beams, assembling a slip form device, erecting a support ring beam scaffold platform, hoisting the steel ring beams, mounting the oblique steel beams, mounting a structure on a cabin top ring beam, hoisting the slip form system, and the like. As module units are assembled on the ground at the same time, the construction working area is increased, the assembling period is shortened, and the constriction duration is effectively shortened. Temperature and wind load influences when the unassembled large steel structure is assembled and measured at high altitude are reduced, the assembling precision is improved, and the engineering quality is ensured. As a great quantity of scaffolds are reduced duo to low-altitude assembling, and only a small quantity of simple scaffolds are needed to be erected, the mounting requirements can be met; meanwhile difficulty in high-altitude working, assembling and hoisting are reduced, and the security risk is effectively lowered.

Description

technical field [0001] The invention relates to a lifting method for a low-altitude modular assembly integral sliding form of a steel structure on the top of a concrete silo. Background technique [0002] In industrial buildings, the storage warehouse is a single reinforced concrete silo structure with a large diameter of more than 50m. Large, long construction period, large safety hazards and difficult to meet the construction requirements of modern cement projects. Contents of the invention [0003] The object of the present invention is to provide a low-altitude modularized assembly overall sliding form lifting method for a concrete silo roof steel structure that is convenient for construction, effectively shortens the construction period, and reduces safety risks. [0004] Technical solution of the present invention is: [0005] A low-altitude modular assembly integral sliding form lifting method for a steel structure on the roof of a concrete silo, which is characte...
