Jack-up installation construction structure of large steel silo

Abstract

The invention discloses a mounting construction structure for a large-sized steel material cabin. The mounting construction structure comprises a basic platform, a first cylindrical section, a cone roof, a second cylindrical section and a bottom plate, wherein the first cylindrical section is arranged on the bottom plate; the cone roof is hermetically connected to the top of the first cylindrical section to form a bell jar structure; the second cylindrical section is arranged outside the first cylindrical section in a sleeving manner and formed by splicing a plurality of arc plates; a vertical gap which is not spliced temporarily is reserved as a movable joint; the two arc plates at the joint have lapping allowance of a certain length; a movable joint tensioning device is further arranged between the two arc plates at the joint; a first seal rubber plate for sealing a gap between the second cylindrical section and the bottom plate is arranged in the first cylindrical section; the mounting construction structure further comprises an air blowing device and a limiting device; and a second seal rubber plate for sealing a gap between the first cylindrical section and the second cylindrical section is arranged on the first cylindrical section. According to the mounting construction structure, the high-altitude operation can be changed to the low-altitude operation, the safety of construction can be enhanced, resources and construction expenses can be saved, the working efficiency can be improved, and the construction period can be shortened.

Description

technical field [0001] The invention relates to the technical field of large-scale industrial equipment installation and construction, in particular to a jack-up installation and construction structure of a large-scale steel silo. Background technique [0002] Large-scale steel silos are widely used in industrial installation projects to contain granular solid substances. They are large-scale industrial equipment and have the characteristics of large diameter, height and weight. Most of this type of equipment is a flat-bottomed cone-top structure, which is composed of a foundation, a bottom plate, a cylinder, and a cone top. The foundation is generally a hollow cylinder several meters above the ground, and there are 5 feeding ports arranged in a plum blossom shape on the top of the foundation. , The steel silo is installed on the top surface of the foundation. The cone top bears the weight of the feeding device, and its skeleton is a truss group structure, so its own weight ...

Problems solved by technology

The disadvantages of the above two methods are: the frontal installation method needs to set up temporary devices for finding circles and scaffolding, and requires large-scale hoisting machinery, which requires high-altitude operations and high risk; although the inversion method does not have high-altitude operations, it needs to use dozens of sets of hoisting equipment. Mechanical equipment, the use of machinery is very expensive, and a lifting device needs to be installed
