Folding multifunctional decoration portable horse stool lifting scaffolding engineering ladder

Portable scaffolding: easy to use (carry), light in size, widely used, free to lift and lower, small scaffolding to improve work efficiency, durable, thickened and widened, anti-slip design, interior decoration, small scaffolding is safe, reliable and quality guaranteed. It is the most handy working partner around you to assist you in your work. Special small scaffolding for putty scraping, direct sales from manufacturers, small scaffolding for interior decoration, high quality and low price! ! ! , the force is transmitted by friction on the contact surface. That is, the friction reaction force after the contact surface at the node is compressed is used to support the load of the cross bar and transfer it to the vertical bar, such as the action of fasteners. Friction force is generated by the positive pressure of tightening bolts
and is transmitted by welding seams. force. Most of the socket connections between horizontal bars and vertical bars are made in this way. Portal scaffolding also belongs to this way
, which directly bears pressure and transmits force. This method is often seen in inner scaffolding where the crossbar is placed on the top of the vertical pole
, and the pin rod is used to resist shear force transmission. That is, the pin rod is used to pass through the vertical connecting plate of the cross bar and the hole of the vertical rod to realize the connection, and the pin rod is subject to shear force on both sides.
Bowl-button scaffolding is a temporary structural frame erected for construction or installation for loading, stacking and construction operations.
.According to the materials used: divided into wooden scaffolding, steel scaffolding and ladders.
.According to whether it is movable: divided into mobile scaffolding and fixed scaffolding.
.According to the nature of construction: it is divided into construction scaffolding and installation scaffolding.
