Lead: Truss, I'm afraid many people don't know how to pronounce these two words. Trusses are very common in our daily life. When we build a stage, many times the spotlights and flashing lights are just placed far away on the shelf, but many people only know it is a shelf, but they don't know it is a truss. There are many bridges, all truss structures, which are not only light in weight, but also high in strength and heavy in bearing. Don't think that trusses are only made of metal, but also wood. Then how was it built? Let's find out.

Product classification:

1. fixed truss: the strongest truss, with high reusability, and the only disadvantage is high transportation cost. Products are divided into square tubes and round tubes. 2. Folding truss: The biggest advantage is low transportation cost and poor reusability. Products are divided into square tubes and round tubes. 3. Butterfly Truss: The most artistic truss with peculiar and beautiful shape. 4. Spherical joint truss: also known as spherical joint frame, it has beautiful appearance and good robustness, and is also the most expensive truss.

Process characteristics:

1, precision welding: large machine, assembly line operation.

2. Baking process: professional spray booth, seiko baking process.

3, standardized processing: large machine positioning, accurate hole location.

4. Technology leadership: first-line research and development, always leading? .

Requirements:

Sufficient strength-no fracture or plastic deformation; Sufficient rigidity-no excessive elastic deformation; Sufficient stability-it will not collapse due to sudden changes in the form of balance; Good dynamic characteristics-earthquake resistance and wind resistance.

Design requirements of truss:? There must be a bar that meets the requirements; There should be good connectors, including rivets, pins and welds. These involve the types of trusses, the sizes and materials of members, but the first is static analysis.

Construction method:

1. Connect all the pillars on the ground first; 2. Connect all beams on the ground; 3 erect any two adjacent pillars, and someone will hold them below to prevent them from falling down; 4. Put the corresponding beam under two pillars, and put a ladder under each pillar. One person holds one end of the beam, the other person holds the other end of the beam, climbs the ladder at the same time, and connects the beam with the upright post through screws; 5 after the beam is connected, someone should hold it below to prevent it from falling; 6. Erect the nearest column and connect another beam in the same way. Note that the beam connected at the back has a certain angle with the beam in front, so that the erected walkway will not fall down; 7 After all columns are erected, connect all beams and check whether the screws are tightened to prevent slipping; Draw and frame the light box cloth, and you're done. According to the above methods, I believe you have a new understanding of trusses. Do it yourself and have plenty of food and clothing. Try it quickly.

Truss plays an important role in our daily life. It always dresses up the most beautiful lanterns for the stage in obscurity. It is the key object of the stage and supports the stage. Truss construction is also important. Good construction methods make the whole truss strong and durable. Studying truss construction methods seriously can not only be responsible for the stage, but also respect your work and take your life seriously. Then the introduction of truss knowledge is here. I hope that the introduction of Bunny will be helpful to everyone's life and work.
