Embodiment
[0011] For the composition of the rigid tie bar structure of the steel structure roof system, refer to the attached figure 1 , adopt the method of the present invention to assemble, carry out according to the following steps:
[0012] 1. Refer to the attached figure 1 , first according to the drawings, each component of the roof rigid tie bar is processed, the steel pipe 8 cuts the end face and the notch, the blocking plate 9 cuts the arc, and the connecting plate 10 drills holes.
[0013] 2. Refer to the attached figure 2 , according to the drawings to make a rigid tie rod assembly mold, the mold is composed of a bottom tire 1, a bottom tire stiffener plate 2, a support 3, a vertical plate 4, a support plate 5, a positioning plate 6, and a positioning pin shaft 7. The bottom tire stiffener 2 is connected to the bottom tire 1; the support 3 is connected to the upper surface of the bottom tire 1, and the support 3 is perpendicular to the upper surface of the bottom tire 1 an...

The invention relates to a method for assembling rigid roof tie rods, which is characterized in that: firstly, according to the drawings of the tie rods, a mold for assembling the tie rods is made, and the tire mold consists of a bottom tire, a bottom tire stiffener, a support, a vertical plate, a support Plate, positioning plate, positioning pin shaft composition. The bottom tire is made of welded or hot-rolled H-shaped steel. The steel bottom tire stiffener is connected to the bottom tire, the support is connected to the upper surface of the bottom tire, the vertical plate is connected to the support plate and the upper surface of the bottom tire, and the positioning plate is connected to the support plate. It is connected with the vertical plate, and the positioning plate has a positioning hole with the same specification as the positioning pin shaft. Put the steel pipe to be assembled on the support, place the connecting plates at both ends of the tie rod on the positioning plates at both ends of the mold and insert them into the notch of the steel pipe, and align the holes on the connecting plate of the tie rod with the holes on the positioning plate , and insert the positioning pin shaft into the hole, and then perform positioning spot welding to complete the assembly operation. Its advantages are: simple operation, convenient use, low cost, high manufacturing precision and work efficiency, and high through-hole rate.
Description
technical field [0001] The invention relates to an assembly method of a roof rigid tie rod, which belongs to the technical field of steel structure manufacturing. Background technique [0002] In various types of steel roof structures, a rigid tie bar is usually longitudinally arranged at both ends and in the middle of the roof truss or roof beams to increase the rigidity of the roof structure. The cross-section of this type of tie bar is a round tube, and a connecting plate with a high-strength bolt hole is welded at each end, and the high-strength bolt is connected to the roof beam to form a roof stiffness system. The previous production method of this kind of tie rod was manual scribing and assembly, that is, drawing the assembly line on the steel pipe and the connecting plate respectively, and then manually assembling according to the marked line. The verticality and the total length of the components, and then the positioning spot welding between the connecting plate a...
