[Grid] node bearing manufacture process engineering grid seat for a single node bearing, bearing from the floor, ribs, bolts ball and tendon and other components (as shown below). Wherein the rib and the bottom plate is carbon steel (Q235B) material, bolt ball is used 45 # steel forging. So welded bearing ribs and bolt ball node node node is a key bearing production plant. At the same time, is also the focus. Here's production process engineering JOINTS do following description: [] To investigate the summary grid bearing grid (net shell) structure supporting manner and bearing designs: the grid (net shell) structure design, lower support structure, bearing type and boundary conditions selected critical to grid (net shell) structure stability, member forces, support reactions, nodal displacement, the amount of steel and the like. [Grid] seat in the actual design analysis and calculation by the integral whole grid and substructure, choose the right lower part of the support structure and bearing type, in order to make the grid (net shell) structure design more safety, economy, reasonable. [Seat] in all types of space grid structure in steel finished sliding bearings manufacturer of rigid system grid (net shell) structure as a higher statically indeterminate beam structure in space, because of its mechanical behavior Good (theoretically lever only by axial force), rigidity, good integrity and seismic performance, strong carrying capacity, by the holder uneven settlement of small, adaptable, and increasingly sophisticated computing and computer technology are rapidly Theory Sliding Bearings finished ball joint development unit price, makes any extremely complex three-dimensional structure analysis and design as possible, and therefore grid (net shell) structure is widely used in industrial and civil fields. But grid (net shell) structure if its supporting structure, bearing type and boundary conditions would be unreasonable design grid (net shell) security and economic structure has important implications [grid] bearing steel construction technology : Grid 1, construction preparation (1) Material 1) steel truss installed steel connecting material, high strength bolts, welding rod, wire, flux, etc., shall meet the design requirements, and should have factory certification. [Grid] bearing steel truss mounting hollow solder balls, solder balls stiffened, bolts ball, semi small fight unit, rods and rubber bearings and other semi-finished products should meet the design requirements and the corresponding national standards . [Grid holder] (2) The main equipment: welding, oxy - acetylene cutting equipment, wheel saws, lever cutting lathe and pole cutting power head, steel tape measure, steel ruler, caliper, level, theodolite, an ultrasonic probe; flaw detectors, magnetic detectors, lifting equipment, lifting equipment, hammer, wire brush, hydraulic jacks, and so on down the chain tool. (3) Operating conditions: [grid] before installing the bearing grid bearing axis response level to carry out inspection line inspection. Grid axis, elevation position must meet the design requirements and related standards. After 2) Before installation check the strength of concrete response capitals, capitals of concrete strength must meet the design requirements and current national standards, can be installed. 3) When using high-altitude slip method to deal with pulley sliding track inspection sliding bearings, sliding horizontal slope shall meet the construction design. [Grid] using strips bearing block installation, sliding table method, response surface table, slip device check and test taxi tests.
