Building from the backwater: chassis, screw, adjusting nut three parts.
Building backwater purposes: the construction process and with the use of steel and scaffolding, scaffolding and can modulate the height of the rack, support the weight balance, load-bearing role in the construction process up to the plane of the applicators used in concrete pouring with the rapid development in recent years, real estate and transportation perspective, the amount of backwater also made progress by leaps and bounds.
Building backwater Category:
1, according to the site can be divided with pop, bottom bracket and pipe bracket. 1-holding on the upper end of the column pipe, the upper end of the chassis, the chassis has a fold; 2) bottom bracket for use in building construction in the lower end of the steel pipe column, in the lower part of the chassis, the chassis can not hem; 3) tube holder is stuck in parallel steel pipe, half-moon notch on the chassis.
2. The screw materials can be divided into: solid and hollow backwater backwater two kinds. Hollow screw backwater thick-walled steel pipe production, lighter; backwater use solid round system, the heavier [1].
3, depending on whether the wheels can be divided into: ordinary round backwater backwater and legs. Pulley galvanized backwater generally used in the lower part of the activities to promote the scaffolding to facilitate the construction process; backwater general use in engineering construction, the support and stability.
4, solid screw backwater according to the production process can be divided into hot-rolled and cold-rolled screw screw. Hot-rolled screw look beautiful, cost is slightly higher; cold-rolled screw appearance less attractive, lower cost.
Construction screw configuration around the manufacturer's production process is similar, the configuration is different, the situation can be configured to distinguish from five aspects:
1) Chassis: chassis thickness and size, specifications and all around the different manufacturers.
2) Welding configuration: can be two ways, the welding processes are welding and friction welding. Welding the welding requirements, very beautiful appearance, low yields, but strong chassis is not easy to fall off; friction welding fast and easy to operate, but not too long screw welding, high yield, prone to fall off the chassis.
3) rib: connecting portion screw and whether the chassis stiffeners, generally based on the requirements of the project, the longer screw backwater directly with stiffener shorter bottom bracket with a little.
4) the length of the screw, usually from 40-70, the thickness of the screw generally φ28, φ30, φ32, φ35.
5) entrusted with the adjusting nut can be divided into two processes: cast iron parts and stamping parts. Each model has a nut adjusting nut severity of the size of the points. Nut shape in two ways: bowl nut and wing nut.
