Clamping plate type support of aluminum alloy hub-type joint net frame

Abstract

The invention provides a clamping plate type support of an aluminum alloy hub-type joint net frame. The technical problem that a screw rod is not subjected to shearing force is solved. According to the adopted technical scheme, the splint type support comprises a maintaining part, a locking assembly, and a connecting part, wherein the maintaining part is provided with a fixing end plate and further provided with a first sealing end plate and a second sealing end plate which are arranged on one side face of the fixing end plate in parallel, and a positioning groove suitable for placing a hub joint is enclosed among the two sealing end plates and the fixing end plate; the locking assembly includes a perforating part passing through the first sealing end plate, the hub joint and the second sealing end plate in sequence in the axial direction of the hub joint, and locking parts arranged at the two ends of the perforating part; and the connecting part is suitable for connecting the maintaining part to a to-be-connected object. Cover plate seals in the prior art is replaced by adopting a clamping type sealing structure, seals are in rigid connection, the overall structural strength of the support is enhanced, thus the perforating part can withstand a certain degree of shearing resistance, and the structural strength of the support is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of large-span steel structures, in particular to a splint-type support of an aluminum alloy hub-type node network frame. Background technique [0002] The traditional spatial grid structure refers to a spatial structure composed of rods and components arranged according to certain rules through node connections, including grid frames, curved reticulated shells, and three-dimensional trusses. The space grid structure system is widely used in industrial and civil buildings, especially in long-span space structures, due to its good overall rigidity and superior technical and economic indicators. The nodes of the traditional space grid structure are generally in the form of bolted balls or welded balls. This node is in the form of a hinge, and the rods only transmit axial force, which is a two-force rod unit. In addition, when connecting grid frames, the on-site nodes are mostly located at high altitudes, and t...
