Detailed Product Description: | Scaffolding (www.ahyyjcc.com) Hebei Hefei the wilderness building materials factory in Hefei, direct marketing business: products required for fasteners of Anhui, Hefei fasteners, Hefei scaffolding, scaffolding Anhui, Hefei mountain type card, Hefei screw through walls and other buildings. Scaffold (scaffold) refers to the construction site for workers to operate and solve the vertical and horizontal transport and erection of various stent. Construction industry generic term that refers to a place on the construction site used in the exterior walls, interior or higher storey construction can not directly. Mainly to the construction workers up and down to work or perimeter security network maintenance and high-altitude mounting member, said White is put on airs, scaffolding making materials usually are: bamboo, wood, steel or synthetic materials. Some projects also use scaffolding when the template, in addition to widely used in the advertising industry, municipal, transportation, roads and bridges, mining and other sectors. Passed between the crossbar with the pole vertical force is divided into 1) the role of force transmission by the contact surface friction. That rely on the node at the contact surface compaction friction reaction force to support the load and passed pole crossbar, such as the role of the fastener on the tight bolts positive pressure creates friction; 2) by weld pass force. Most crossbar with the pole of the socket coupling is used in this way, the door frame also belongs in this manner; 3) direct pressure force transmission. This way is more common in the crossbar shelved scaffolding pole top; 4) by pin lever shear force transfer. Vertical coupling plate and pole holes through the crossbar with a pin lever to achieve the coupling, the pin lever sided by the shear force. This approach have been rare in the junction of the crossbar and pole. In addition, the pole and pole join, there are three kinds of force transfer mode: 1) socket docking supporting force transmission. The upper and lower pole butt, connecting rod or intubation to ensure the good condition of the docking; 2) the pin lever connected to the pin lever shear force transfer; 3) threaded connection meshing force transfer. I.e. the inner pipe the external thread and the outer tube (sets) the inner threaded engagement of the force transmission. Connection of the latter two is used for force transmission pole to adjust the height requirements. |
