Classification of steel truss structures

1, fixed truss

The strongest of the trusses are highly reusable, with the only drawback being high transportation costs. The products are divided into square tube and round tube.

2, folding truss

The biggest advantage is low transportation cost, slightly less reusable. The products are divided into square tube and round tube.

Butterfly truss

The truss is one of the most artistic, peculiar and beautiful in shape.

3, ball joint truss

Also called the ball frame, beautiful shape, good firmness, is also the highest cost of a truss. Steel structure truss is usually used in bridge and large-span gymnasium building, which has unique shape and exquisite appearance. With the development of the construction industry, people's pursuit of beauty is higher and higher, most of the steel beams of the steel structure workshop also use the steel structure truss structure. Below, xiaobian for you to explain the technical requirements of steel structure truss processing!

1, large steel structure truss processing generally as far as possible in the ground frame of a single truss assembly welding, and then hanging to the top of the column in place, and then welding the transverse bar between the trusses.

2, such as truss span and dead weight beyond the mechanical capacity of lifting, generally on the ground according to the weight of the segmented welding. Between each section of the equipment temporary bolt fixed joint, sectional assembly welding after the completion of the weld and the size of each part of the inspection, and then disassemble the temporary fixed bolt at the section, lift section by section to the installation position on the platform, welding the closing weld.

3. No matter on the ground or in the air, the middle joints shall be welded first, and then the joints at both ends of the truss shall be extended in accordance with the welding sequence to avoid dimension error between the joints and the frame, and welding shall not be applied at both ends of the same straight pipe.
