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.
