Three Strength Bearing Models of Dual Frame Body in Frame Scaffolding System
Frame scaffolding with spell quickly down the energy saving, safe and stable features, such as scaffolding set-up at the top and can be applied to surface, the most common is built for double row scaffolding system.
Double row feet hand is mainly used in the body of the high-rise building construction outer wall protection, its security by the Frame of the frame body bearing size, node construction standards, etc. Therefore, in order to build the scaffolding on the safe side, we need Frame scaffold stress distribution were analyzed, and the following three aspects: its force.
1, the frame scaffold pole stress buckling analysis
Single stem force: as a frame body composition has a stud, horizontal bar, horizontal and longitudinal rod, vertical diagonal, diagonal and water flat along the transverse direction.
According to the test, the above several kinds of bar to force minimum horizontal pole, and poling largest stress, diagonal center. A lot of work Cheng scaffolding collapsed instance proved so. This article will highlight poling force analysis.
2, poling under its own gravity, the upper layer spread under the load and operation levels longitudinal rod load and horizontal bar transmission load of vertical and horizontal rod are rows of wooden under concentrated load or line load that came from the bamboo and stable longitudinal frame body.
3, according to the principle of theoretical mechanics, the frame body foundation as a new piece, the whole frame body as a by a number of vertical to in connection with the building wall attachment point of the space bar just slice, frame body just piece and foundation just piece by plane articulated connecting rod base.
