Embodiment approach

[0028] 1), in the described step of decomposing nodes, first construct the isotangent plane between each node lobe (that is, the bisector of the angle between the adjacent nodal lobe), and utilize the isotangent plane to evenly decompose the node into number and the number of petals of the node The same node lobe and a central cylinder; and number the nodal lobe according to a certain direction (clockwise or counterclockwise), then collect the geometric data of each structural unit, and generate a formatted data file containing node geometric information;

[0029] 2), in the blank making step of described structural unit, the size of the node flap blank is the maximum size that can form each node flap unit module shape after the above-mentioned decomposition, such as a cuboid of standard length, also can be triangular prism, cylinder body etc. The central cylinder can be obtained by machining standard round steel or cast round steel;

[0030] Production of node flap blanks: ...

Abstract

The invention relates to a method for manufacturing a multi-rod converging valve type space net shell node. The method comprises the following steps that: each converging valve type space net shell node is decomposed into several independent structure units, wherein the structure unit comprises a plurality of node valves and a central cylinder; a steel structure blank of the structure unit is manufactured according to geometric data of the structure unit; the node valve blank is processed according to geometric intersecting information of each structure unit so as to form a node valve module with a welding groove, a datum hole and a datum plane are processed for the central cylinder so as to form a central cylinder module; the structure unit modules formed in the same group are positioned and spliced on a tooling workbench, and adjacent node valves, the node valve module and the central cylinder module are subjected to spot welding in sequence so as to form nodes; the nodes are welded; the nodes are subjected to thermal treatment; and the nodes are subjected to treatment and surface treatment. The method has the advantages of short manufacture process flow, high automatic degree, high production efficiency and low manufacturing cost.

Description

(1) Technical field [0001] The invention relates to a manufacturing method of a welded reticulated shell node. The invention belongs to the technical field of structural components of steel structures. (2) Background technology [0002] Due to its novel and beautiful shape, light weight, large span, good seismic performance, high dimensional accuracy and short construction period, steel structure buildings have been widely used in various large venues, infrastructure, towers and other fields, such as: stadiums, Iconic buildings such as the Convention and Exhibition Center and the Radio and TV Tower. The node is an important structural component in the steel frame structure. It plays the role of connecting the intermediate rods and transmitting the internal force of the rods. Therefore, the manufacturing quality of the nodes will affect the stress and safety of the overall grid. At the same time, the level of manufacturing technology will also affect the aesthetics of the n...
