Embodiment
[0028] Example: such as figure 1 , figure 2 and image 3 As shown, a processing method for welding a box with rounded corners includes the following steps:
[0029] Step 1: U-shaped wall plate Ⅰ10, L-shaped bent wall plate 12 and U-shaped wall plate II14 are bent by hydraulic press and forming mold;
[0030] Step 2: Take a U-shaped wall plate Ⅰ10, assemble the head partition 3 and the transition inner partition Ⅰ11 on both sides of the U-shaped wall plate Ⅰ10 and weld them, then take a U-shaped wall plate Ⅰ10, and put the two The U-shaped wall plate I10 is welded with the head partitions 3 at both ends and the transition inner partition I11 to form the upper box-shaped column 5 . The grooves of the head partition 3 and the transition inner partition I11 face outward, and the position and inclination deviations are not greater than 2.0mm.
[0031] Step 3: Weld the four L-shaped bent wall panels 12 in a circular shape to form a gradual transition box-shaped column 6, and ma...

The invention relates to a processing method of a welded box with rounded corners, which belongs to the technical field of building steel structures. The first step is to perform bending processing of U-shaped wall plate I, L-shaped bent wall plate and U-shaped wall plate II. Step 2: Carry out welding seam splicing to form the upper box-shaped column. Step 3: Weld the four L-shaped bent wall panels in a circular shape to form a gradually transitional box-shaped column. Step 4: Carry out weld seam splicing to form the lower end box column. Step 5: Assemble the upper box-shaped column, gradual transition box-shaped column, and lower-end box-shaped column in sequence and complete the welding butt weld. Step 6: Weld the H-shaped cow feet at the front end to the front end of the upper part of the lower box-shaped column, and weld and fix the H-shaped cow feet at the side ends on both sides of the upper part of the lower box-shaped column. Step 7: Finally, weld the hoisting ear plates on the upper four sides of the upper box-shaped column, and weld the lower hoisting ear plates on the lower four sides of the lower box-shaped column. It has the characteristics of low structural strength, convenient construction and short period. It solves the problem of low efficiency of traditional factory production.
Description
technical field [0001] The invention relates to the technical field of building steel structures, in particular to a processing method for a welded box with rounded corners. Background technique [0002] Large-scale civil engineering structures are changing with each passing day, and the application of large-scale grid structures is also becoming more and more extensive. The types of joints used in grid structures usually include welded or screwed steel plate joints, welded hollow ball joints, bolted ball joints, intersecting joints and cast steel joints, etc. [0003] In recent years, with the rapid development of my country's building steel structures, large-section thick-walled welded box members have been widely used in long-span steel structures, high-rise and super high-rise structures. It has the following characteristics: [0004] 1. The structure is simple, and it can adapt to the design requirements of large-load and long-span steel structures. It is adopted by ma...
