How to assemble gusset billboards

When installing, first fix the keel on the basic frame and snap the buckle plate in once. Various specifications of keel gaps are available. The standard distance between two keels is 50px. For occasions with higher strength requirements, it can be appropriately encrypted. Connection method: Overlap: The two gusset plates are directly connected to each other, which is simple and practical, but the amount of overlap needs to be calculated. Docking: Using the gusset plate itself as a connecting piece can achieve a better linking effect and make full use of the good materials produced during construction. Before assembly, the surface of the color steel gusset plate must be kept clean, such as there should be no rust, burrs and oil around the weld; the deviation of the welded connection during assembly must comply with the regulations and shall not be allowed to exceed the regulations; the area of ​​the contact area of ​​the polished top There is a requirement that this area occupies approximately 75%. During inspection, a 0.3mm feeler gauge must be used for measurement. The sum of the areas inserted by this feeler gauge must be less than 25% of the total area, and the maximum gap at the edge must also comply with regulations. When installing components, formwork or large-scale longitudinal installation is required. The allowable deviation of the axis intersection is stipulated. This requirement is that it must be smaller than the positioning point. The model of the positioning point welding material should be the same as the material used for formal welding. When performing spot welding, the spot welding height should be within 2/3 of the designed weld height, the spot welding length should be less than 40mm, and the spacing of 500-600mm is appropriate. There are requirements for operators who perform spot welding. This person must have a qualification certificate for spot welding. After the spot welding operation is completed, there should be no pores or cracks around it. Fix the gusset plate keel on the square tube frame with rivets; then the color steel gusset plate will be buckled by pre ssing it with your hands; you decide how many keels to use based on the size. It is best to add gusset plate keels to the upper and lower borders so that they are strong. Color steel refers to color-coated steel plate. Color-coated steel plate is a kind of steel plate with organic coating. It has the advantages of good corrosion resistance, bright color, beautiful appearance, easy processing and molding, and has the original strength of steel plate, and it also has low cost. and other characteristics.
