Bowl buckle scaffold and fastener type scaffolding
Below the support bar bowl for 360 degrees placed, however, and there is no fixed connection position, if the combination of high and large, it will obviously look askew, poor accuracy, and generally no design of diagonal bars, bearing capacity.There is no reliable inclined rod fixed, must be used in addition to the steel pipe and the activities of the tight junction to do the reinforcement, the reinforcement of the steel pipe and the activities of the tight junction due to the material and artificial application of the relationship, there is a lot of instability. And because of the lack of effective length and poor accuracy, the bearing capacity will be greatly reduced with the increase of height, it is difficult to assess the bearing strength, which is more dangerous and backward.
The bowl buckle frame is slow, the combination of each node, the upper lid must be turned up and then put all the bars to be fixed.
In the 40s of last century, the United Kingdom, more than 50 years of foreign use. After so many years of use, because of the carrying capacity is not easy to control, most of them can only be used as the construction of such a lighter load of the project.
