[Grid] bearing grid (net shell) bearing node structure should be able to ensure safe and reliable transmission of supporting reaction force, and therefore must have sufficient strength and rigidity. In the vertical loads, the support nodes in general are under pressure, but in some kind of diagonal grid, the local node can withstand tensile force bearings, and sometimes may have to bear the effect of horizontal forces, the design should make support Block node configuration to adapt their mechanical characteristics. While bearing structure nodes should also try to meet the calculation assumes fully reflect the design intent. [] Since the grid bearing grid (net shell) structure is statically indeterminate higher lever system, constraints, bearing a greater impact on the grid nodes nodal displacements and member forces; constraints in the construction and Differences between design will directly lead to changes in reaction force member forces and bearing, sometimes resulting member forces change numbers. So the grid (net shell) design structure bearing the node should be given adequate attention. 3. Treatment of boundary conditions [grid] bearing a fixed boundary conditions, elastic restraint, oblique border and forced displacement. Steel grid bearing technology leader in grid (shell) structure finite element calculation! The boundary conditions of internal forces and deformation of the grid structure will have a greater impact. Boundary conditions and grid support at both bearing node configuration, but also on the stiffness of the support structure and related support may be no sway, unidirectional and bidirectional lateral lateral hinge bearing grid bearing, a support structure (columns, beams, etc.) may be rigid or flexible. [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 through analysis and calculation of the overall grid and the lower structure fused choose the right lower part of the support structure and the bearing type bearings offer welcome advice grid type! In order to make the grid (net shell) structure design is more secure, economical and reasonable. [Seat] in all types of space grid structure, the rigid system of the grid (net shell) structure as a higher statically indeterminate beam structure in space, due to the good performance of its force (theoretically limited only by the lever axial force), rigidity, good integrity and seismic performance, strong carrying capacity, by the holder uneven settlement of small, adaptable, and increasingly sophisticated theoretical calculations and computer technology is developing rapidly, so that any extremely complex Analysis and design of three-dimensional structure is possible, 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) structure of the security and economy has important implications grid holder _ welcome to consult the grid support Block quote type! _ Manufacturers large favorably by-Engineering Rubber Co., Ltd.
