The connecting plate 300 includes multiple connecting plates of different sizes. The connecting plate 300 of corresponding size is selected according to the limiting distance between the first purlin 001 and the second purlin 002. According to the actual situation of the construction site, the required limiting distance can be measured and the appropriate connecting plate 300 can be selected. After the connecting plate 300, the hook-type right-angle base plate 100 and the concave base plate 400 are installed, the first purlin 001 is hoisted and installed. When installing the next purlin (the second purlin 002), just put the second purlin 002 into the second bearing frame of the concave base plate 400 (right side) 4 and fix it by twisting the third spiral fastener 530 to prevent the second purlin 002 from shaking left and right.
