Problems solved by technology

[0003] The purpose of the present invention is to provide a reinforcement structure and method that can significantly enhance the stability of the H-shaped column for the column in the wallboard-H-shaped section column structure system, so as to solve the problem that the existing dust collector box column is prone to failure. The problem of stable failure and low utilization rate of material strength can reduce the design section of the column, reduce the self-weight of the structure, and thus reduce the production cost

Embodiment 1

[0035] The thickness t of the wall panel of the dust collector box is 7mm, the width w of the wall panel is 3500mm, the spacing s of the angle steel stiffener is 1170mm, and a horizontal support is provided every three stiffener spacings (the spacing of the lateral support is l=3s), the total height of the column H is 11990mm, and the column section is H200mm×150mm×6mm×9mm (section height h×flange width b f × web thickness t w × Flange thickness t f ).

[0036] When the lateral load is small, the initial bending and torsion deformation of the column section is constructed within the range of 0-0.08l below the column top; when the lateral load is large, the initial bending and torsion deformation is constructed within the range of 0.24l-0.32l. Calculate the bearing capacity of the column when the lateral load is 3000Pa and 9000Pa, and the stable bearing capacity before the stability of the column is enhanced is shown in Table 1.

Embodiment 2

[0038] Using the model parameters in Example 1, the stability-enhancing construction measures are adopted for the column simulation, the distance d between the vertical connection weld of the reinforced steel plate and the wall plate is 0mm from the joint weld of the wall plate and the rear flange of the column, and the thickness of the reinforced steel plate is t s It is 1 times the thickness of the wallboard, and the reinforcement section is the first stiffener section. The stable bearing capacity after the column stability is enhanced is shown in Table 1.

Embodiment 3 and Embodiment 4

[0040] Compared with Example 2, Embodiment 3 and Embodiment 4 only change the distance d between the vertical connection weld between the reinforced steel plate and the wall panel and the connection weld between the wall panel and the rear flange of the column in the stability-enhancing structure, and the specific construction parameters and the stability of the column The bearing capacity comparison is shown in Table 1.

Abstract

The invention discloses a stability enhancing structure and method for an H-shaped section column of a dust remover box body and belongs to the technical field of structural engineering. According to the stability enhancing structure disclosed by the invention, reinforcing steel plates are welded to two sides of a front wing edge of the H-shaped section column at adjacent stiffening rib areas of a wall board with stiffening ribs, and the other sides of the reinforcing steel plates are welded to the wall board. The invention definitely provides a designing method for the stability enhancing structure of the H-shaped section column at the same time. After the stability enhancing structure is implemented, the stable bearing capacity of the column is greatly improved based on an original structure, and the designed section of the column is further reduced. Furthermore, the stability enhancing structure is convenient to process and manufacture, saves steel and has low production cost.

Description

technical field [0001] The invention relates to a structure and method for enhancing the stability of an H-shaped cross-section column of a dust collector box, and belongs to the technical field of structural engineering. Background technique [0002] The dust collector is the main environmental protection equipment widely used in thermal power, metallurgy, chemical industry, building materials and other industries to eliminate smoke and dust, and the box (also called the shell) is the most important process part. When the enclosure structure of the box body adopts the stiffened straight steel plate wallboard-H-shaped (or I-shaped) cross-section column structure system, the side flange of the H-shaped cross-section column is continuously welded to the steel plate wallboard. The wall panels in the box are subjected to lateral loads caused by negative pressure and wind loads, and the lateral loads acting on the wall panels will be transferred to the columns, so that the column...
