Abstract
The utility model relates to a composite ball used for the connecting point of a metal net frame. The primary structure of the composite ball is formed by a bearing ball body which is formed by welding after punch forming by a low carbon steel plate and a low alloy steel plate and an outer coating body which is formed by the punch forming of a stainless steel plate and thin non-ferrous metal, such as copper or a copper alloy plate, and the outer coating body is tightly coated outside the bearing ball body and is provided with a high-grade appearance; the fabrication technology of the composite ball is that the bearing ball body is punch formed and welded first, and the outer coating body is coated by stainless steel or the non-ferrous metal. When the composite ball is used, the composite ball is connected with a net frame rod together to form a net frame structure in the method of argon arc welding or stainless steel arc welding.
Description
The utility model relates to a kind of composite balls that is used for the metal truss node, belongs to metallic structures for building.
Adopt the high-intensity metal truss structure of large span in the builing industry in a large number, the node of rack connects with Metal Ball.At present used Metal Ball is most for being welded after low carbon steel plate or the low alloy steel plate punch forming, and the Metal Ball of top-grade building rack is welded after with the corrosion resistant plate punch forming, and the former presentation quality is poor, corrosion-resistant; And the latter involves great expense, and very low as the thick corrosion resistant plate finish of carrying, polishes very difficult.Because space truss structure is huge, be difficult to low-carbon (LC) or low-alloy rack are implemented surfacings such as platings, also be that the follow-up welding and the processing of weld seam bring very big difficulty even if implement electroplating processes, so can only on-the-spot brushing paint.But coating is easily aging, and antiseptic effect is poor, and the life-span is short, and decorative effect is poor, needs to carry out the high-altitude maintenance activity regularly, and difficulty is very big.
The purpose of this utility model is to design the stainless steel of the high-intensity mild steel of a kind of usefulness or low-alloy steel and best bright finish or the metal truss node composite balls that non-ferrous metal light sheets such as copper and copper alloy are made.
The structure of this composite balls mainly is external the outer cladding that closely coats non-ferrous metal boards such as the stamping forming thin corrosion resistant plate of one deck, sheet copper or thin copper alloy plate of bearing ball that is welded after low carbon steel plate or low alloy steel plate punch forming.
The utility model has the advantages that: both had the high strength of mild steel or low-alloy steel, had the high corrosion-resistant and the high class appearance of stainless steel or non-ferrous metal light sheets such as copper and copper alloy again, processing technology thereof is simple, and cost is low, and is easy to install.
Describe structure of the present utility model and processing and fabricating and installation and application in detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional drawing of composite balls.Marginal data is as follows: (1) outer cladding; (2) carrying spheroid.
Its processing and fabricating method of composite balls shown in Figure 1 is as follows:
The mild steel or the low alloy steel plate that at first with thickness are 2～20mm strike out hemisphere, and two hemispheres are welded into hollow ball.With thickness is that stainless steel or the sheet materials such as non-ferrous metal such as copper and copper alloy of 0.1～2mm strike out hemisphere corresponding to above-mentioned low-carbon (LC) or low-alloy steel hollow ball size, then two hemispheres closely are coated on corresponding low-carbon (LC) or the low-alloy steel hollow ball, with argon arc welding, plasma arc welding (PAW) or laser welding method, be welded into outer cladding as a whole, the finishing weld seam carries out surface finishing again.
Its installation and application of composite balls shown in Figure 1 is as follows:
According to the design of space truss structure, with composite balls and the welding of rack bar, welding manner is argon arc welding, stainless steel electrode arc welding, postwelding finishing weld seam.
Claims (1)
1. a composite balls that is used for the metal truss node is characterized in that: external outer cladding that closely coats non-ferrous metal boards such as the stamping forming thin corrosion resistant plate of one deck, sheet copper or thin copper alloy plate of the bearing ball that is welded after low carbon steel plate or low alloy steel plate punch forming.
