Problems solved by technology

[0002] The upper feed steel structure of the spherical warehouse is generally a super-high, super-long, super-heavy truss and needs to span the main structure of the half-width spherical warehouse. During the installation period, it will be affected by the ground assembly site and the construction progress of the upper grid of the spherical warehouse. The construction is suspended when it is installed 2 meters below the height of the truss. The installation efficiency is not high, the cost is high, and the safety is insufficient.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiment:

[0022] Taking the on-site construction conditions of the first phase of the China Power Investment Coal Wharf Project in Yancheng Port Binhai Port Area as an example, the installation process of the super-large truss spanning the spherical warehouse is introduced. The specific steps are as follows:

[0023] (1) Segmentation of truss and ground assembly

[0024] According to the truss structure diagram, the relative position of the outer truss column of the spherical warehouse and the relative position of the central column in the warehouse, the truss is divided into the inner truss section and the upper truss section of the warehouse wall; when the truss is divided into the inner truss section and the upper truss section of the warehouse wall Two requirements: the location of splitting is to choose the truss node close to the warehouse wall in the spherical warehouse, and at...

Abstract

The invention discloses a mounting process of an extra-large truss of a cross-spherical bin. The mounting process comprises the following specific steps of (1) sectioning and assembly on the ground of the truss, (2) designing and erecting of temporary supports, (3) hoisting and temporary reinforcing of truss sections on the upper portion of the bin wall, (4) hoisting of truss sections in the bin and (5) dismantling of the temporary supports. The provided mounting process of the extra-large truss of the cross-spherical bin differs from a whole traditional mounting process of an extra-large truss of the cross-spherical bin, assembly is conducted in sections, and a field in the spherical bin does not need to be occupied for long time and in large areas; during smooth hoisting, due to the fact that tonnage is reduced greatly after sectioning, type selection of a crane and the requirement for a hoisting field are reduced greatly; it is guaranteed that under the premise of not being restricted by construction of a net rack on the upper portion of the spherical bin and the assembly field in the bin, 'penetrating mounting' of the truss is achieved, and the effect of intersection construction is furthest avoided; and efficiency is improved, the cost is saved, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the installation field of a spherical warehouse and its subsidiary steel structure, in particular to an installation process of a super-large truss spanning a spherical warehouse. Background technique [0002] The upper feed steel structure of the spherical warehouse is generally a super-high, super-long, super-heavy truss and needs to span the main structure of the half-width spherical warehouse. During the installation period, it will be affected by the ground assembly site and the construction progress of the upper grid of the spherical warehouse. When the installation is 2 meters below the height of the truss, the construction will be suspended. The installation efficiency is not high, the cost is high, and the safety is insufficient. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides an installation process of a super-large truss spanning a spherical warehouse. ...
