Description
Technical Field
The invention relates to the technical field of steel structure construction, in particular to a method for reducing welding workload of a closed space in a box-shaped member with a section shaped like a Chinese character 'mu'.
Background
With the wide application of steel structures, box-type members with unique shapes are more favored by designers, and various box-type structures with complex forms are continuously derived. In the steel structure, the box-shaped member with the cross-section shaped like a Chinese character 'mu' can bear tension and effectively resist pressure due to the fact that the box-shaped member with the cross-section shaped like a Chinese character 'mu' contains two longitudinal partition plates and a plurality of transverse partition plates, so that the box-shaped member has good mechanical property, is the first choice of a structural form of a pressure ring beam in a cable membrane structure with certain large span, but can form a plurality of closed spaces in the box body due to the characteristics of the structural form, further needs to perform welding operation in the closed spaces, causes great hidden dangers to safety production, and seriously harms the personal health of staff.
Disclosure of Invention
The invention aims to overcome the defects and provides a method for reducing the welding workload of the closed space inside the box-shaped member with the herringbone cross section.
In order to achieve the above object, the present invention is realized by:
a method for reducing the welding workload of the closed space in a box-shaped member with a cross section in a shape of Chinese character mu includes
Step 1, laying a bottom plate (1) of a box-shaped member with a cross section in a shape of Chinese character mu on a jig frame;
step 4, assembling a top plate (4) of the box-shaped member with the cross section in the shape of Chinese character 'yi', a transverse partition plate (2) and a longitudinal partition plate (3) to form a state in the shape of Chinese character 'yi', welding the transverse partition plate (2) and the top surface in a box body, forming an internal smoke exhaust channel by using a manhole of the transverse partition plate (2) or the longitudinal partition plate (3), and arranging blowers at two ends of the box body of the box-shaped member with the cross section in the shape of Chinese character 'yi' to ventilate and exhaust smoke; the open groove of the longitudinal clapboard (3) is welded in the open space; checking the size and the welding line of the welding line, and performing the next operation after the welding line is corrected to be qualified;
step 5, assembling a sealing plate (5) of the box-shaped component with the section shaped like a Chinese character 'mu', a diaphragm plate (2), a top plate and a bottom plate (1), and then welding a main welding seam of the box-shaped component with the section shaped like a Chinese character 'mu';
and 6, welding the diaphragm plate (2) and the closing plate (5) in an electroslag welding mode, so that the welding workload of the closed space is further reduced.
As shown in fig. 1, for the conventional method, the conventional organization process is still used in the process of processing and manufacturing, that is, the stable U-shaped structure is assembled and then assembled into the box-type structure, so that the internal longitudinal and transverse partition plates are not welded with the top plate, and therefore a large amount of welding work is required to be finished when a welder enters the interior through the top plate opening, and finally, the safety risk of welding work in the closed space is brought. In addition, the manhole channel is usually arranged on the central box body of the component with the cross section shaped like a Chinese character 'mu', the partition plates in the box bodies on the two sides need to be assembled and welded in a mode of removing the assembly and the welding, or a plurality of temporary manholes are arranged on the panel and enter the box body for welding, and the welding operation in a narrow closed space exists in the two methods, and the efficiency is low. The method overcomes the defects, reduces the welding operation in the closed space and thoroughly eliminates the potential safety hazard caused by the operation of welding personnel in the closed space in the processing and manufacturing process of the box-shaped member with the section shaped like a Chinese character 'mu'.

FIG. 1 is a schematic diagram of a conventional welding operation.
FIG. 2 is a schematic view of a welding operation of the present invention.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in FIG. 2, a method for reducing the welding operation amount of the closed space inside a box-shaped member with a cross section in a shape of Chinese character mu, comprises
Step 1, laying a bottom plate (1) of a box-shaped member with a cross section in a shape of Chinese character mu on a jig frame;
step 4, assembling a top plate (4) of the box-shaped member with the cross section in the shape of Chinese character 'yi', a transverse partition plate (2) and a longitudinal partition plate (3) to form a state in the shape of Chinese character 'yi', welding the transverse partition plate (2) and the top surface in a box body, forming an internal smoke exhaust channel by using a manhole of the transverse partition plate (2) or the longitudinal partition plate (3), and arranging blowers at two ends of the box body of the box-shaped member with the cross section in the shape of Chinese character 'yi' to ventilate and exhaust smoke; the open groove of the longitudinal clapboard (3) is welded in the open space; checking the size and the welding line of the welding line, and performing the next operation after the welding line is corrected to be qualified;
step 5, assembling a sealing plate (5) of the box-shaped component with the section shaped like a Chinese character 'mu', a diaphragm plate (2), a top plate and a bottom plate (1), and then welding a main welding seam of the box-shaped component with the section shaped like a Chinese character 'mu';
and 6, welding the diaphragm plate (2) and the closing plate (5) in an electroslag welding mode, so that the welding workload of the closed space is further reduced.
Compared with the advantages of the traditional method, the method has the advantages that the ventilation in the box-type member is enhanced in the welding operation process, meanwhile, the generation of smoke dust of a weldment is reduced as much as possible in the welding operation process, and the problem of potential safety hazards in the welding operation process of the traditional box-type member is further solved.
