The present invention relates to a process of producing a boom part from a sheet metal blank, in particular a process of producing a boom part having a bearing seat, in which the starting material is merely formed by bending. Thus, the production process is simplified. In addition, the present invention relates to a process of producing a boom that is closed at both ends by joining two boom parts produced by means of the process of the present invention. Furthermore, the present invention comprises boom parts and booms which are produced by means of one of the processes according to the present invention.

A connecting assembly includes: a connecting pipe, an inner wall of at least one end of the connecting pipe being provided with a pre-embedded nut, and the nut being coaxial with the connecting pipe; a connecting plate, the connecting plate being provided with a fixing hole; and a fastener, the fastener penetrating through the fixing hole and being in threaded fit with the nut. The connecting pipe is a light alloy component, and the connecting plate is a steel component. The connecting pipe is the light alloy component, the inner wall of at least one end of the connecting pipe is provided with the pre-embedded nut, and the fastener sequentially penetrates through the fixing hole on the connecting plate of a steel material and is in threaded fit with the nut at one end of the connecting pipe.

The present invention proposes a novel construction system consisting of the attachment of modified hyperboloid shaped-structural elements called “laminate cells” which, when working together, create a structural system with integrated over having the capacity of absorbing and transmitting in all directions and orientations.
