[0020] The connecting holes between the main support (1) and the cross support (2) are drilled in the factory and then tapped with an extrusion tap. The connecting holes at both ends of the main support (1) are directly drilled on the main support (1). The cross support (2) and the connecting plate (3) components are welded in the factory and shipped. The built-in joint (4) is cut with a laser.
[0021] During on-site assembly, first place one main support (1) on each side flat on the ground. Three cross supports (2) are required on each side. After the three sets are installed in place, tighten them with an electric torque wrench. This structure requires two sets of assembly.
[0022] After assembling the two groups, use the cross brace (2) components to connect and tighten with the reinforcing plate (5). In this way, the four main supports (1) of the entire frame at the bottom section are erected. Since it is an overall square structure, it can stand up. Use an infrared level to check the level and verticality and then weld it firmly with the embedded parts on site. Then put the built-in joint (4) into the connection hole of the upper main support (1) and fix it with the main support (1). Insert the upper main support into the built-in joint (4) and fix it with bolts. Repeat the above steps to install the other three in place and tighten them in turn.
[0023] Screw the bolts into the threaded holes of the main cross brace (1), install the cross brace (2) assembly in place and tighten it. This completes the second section assembly. You can assemble it in the same way as you need.
[0024] The connecting holes of the main support (1) and the cross support (2) are processed in the factory by a radial drilling machine. The thickness of the profile is stretched on the parts with a hot melt drill bit to increase the depth of the thread to achieve the fastening strength. After drilling, the hole diameter is 10.5mm, and then the M12X1.75 thread is tapped with an extrusion tap. The connecting holes at both ends of the main support (1) are directly drilled with a twist drill on the 100mm width side and the 50mm side of the main support (1). The hole spacing is 60mm from the end face and the hole spacing is 120mm. There are 6 holes in total. The cross support (2) and the connecting plate (3) components are welded and shipped in the factory. The built-in joint (4) is cut by laser with a hole spacing of 120mm. After processing and bending, 12 M12X1.75 national standard nuts are welded on each piece. The connecting plate (3) and the reinforcing plate (5) are stamped and formed by molds. After the above parts are processed, the surface is processed according to customer requirements and then put into the finished product warehouse.

In this way, three cross support (2) assemblies are required on one side. After the three sets are installed, they are tightened with an electric torque wrench. This structure requires two sets of assembly. After assembling the two groups of standing up, use the cross brace (2) components, M12X30 hexagonal bolts (GB / T 1228-1991), Φ12 spring washers (GB / T7244-1987) and the reinforcing plates (5) to connect and tighten them respectively. In this way, the four main supports (1) of the entire frame of the lowest section are erected. Because it is an overall square structure, it can stand up stably. After using an infrared level to find the level and verticality, weld it firmly with the embedded parts on site (reserved in advance by the customer). Then put the built-in joint (4) into the joint hole of the upper main support (1), and use M12X30 national standard hexagonal bolts (GB / T 1228-1991), Φ12 spring washers (GB / T 7244-1987), Φ12 flat washers (GB / T95-2002) for 6 each, insert the upper main support into the built-in joint (4) and fix it with M12X30 national standard hexagonal head bolts (GB / T 1228-1991), Φ12 spring washers (GB / T 7244-1987), Φ12 flat washers (GB / T 95-2002) for 6 each, repeat the above steps to install the other three in place and tighten them. Then repeat the steps in the last section, screw the M12X30 hexagonal head bolts (GB / T 1228-1991), Φ12 spring washers (GB / T 7244-1987) and reinforcing plates (5) into the threaded holes of the main support (1), leaving a 10mm gap so that the cross support (2) assembly can be quickly installed through the small gap.
