Abstract

The invention relates to an assembly type steel pipe tower outer sleeve type node. The assembly type steel pipe tower outer sleeve type node comprises an upper main pipe and a lower main pipe which are connected, and further comprises an outer sleeve and a plurality of stiffening ribs. The outer sleeve is arranged at the periphery of the connecting end of the upper main pipe and the lower main pipe and is fixedly connected with the upper main pipe and the lower main pipe through rivets. The plurality of stiffening ribs are uniformly distributed and fixedly connected to the outer surface of theouter sleeve and the upper and lower end surfaces of the outer sleeve. For a node needing to be connected with a supporting rod or a supporting pipe, the stiffening ribs are used as inserting platesand are provided with connecting holes, and a high-strength bolt penetrates through the connecting holes to fixedly connect the supporting rod or the supporting pipe to the stiffening ribs. During field assembly, the upper main pipe is hoisted, the stiffening ribs and the upper end surface of the lower main pipe are jointly used as temporary supports when the upper main pipe is assembled, and an LMB type single-sided pulling rivet is connected with the outer sleeve. The assembly type steel pipe tower outer sleeve type node is simple in structure and clear in stress, the pulling rivet is sheared, the design of the node is facilitated, the construction is convenient, and the assembly level of a power transmission line steel pipe tower can be improved.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to an assembled steel pipe tower outer sleeve type node. Background technique [0002] Prefabricated steel structures have the advantages of production industrialization and construction assembly, so prefabricated steel structures are more and more widely used in the engineering field. In electric power engineering, due to the development of steel structure transmission towers towards high voltage, large capacity, and multiple circuits, the tower shape becomes larger and the construction difficulty increases, and the demand for the assembly of transmission towers is increasingly strong. The force transmission path of traditional steel pipe tower joints is not clear, and the failure form is complicated, which makes it difficult to meet the requirements of fabricated steel structures. Therefore, it is of great engineering significance to develop a new node suitable for the a...
