Net rack plate type rotating support

Abstract

The invention provides a net rack plate type rotating support, which comprises a base, a vertical plate, four longitudinal stiffening plates, a lateral assembly and a support ball, wherein the vertical plate is in groove welded connection with a bottom plate; the longitudinal stiffening plates are in groove welded connection with the bottom plate and the vertical plate; the lateral assembly comprises a lateral transition plate, a lateral bottom plate and two lateral stiffening plates; the lateral transition plate is in bolt connection with the lateral bottom plate; the two lateral stiffening plates are arranged symmetrically on the front side and rear side of the plate body on the upper left part of the vertical plate and are in groove welded connection with the lateral bottom plate and the vertical plate; and the support ball is arranged in a space which is encircled by arch-shaped gaps of the vertical plate, the longitudinal stiffening plates and the lateral stiffening plates and is welded with the vertical plate, the longitudinal stiffening plates and the lateral stiffening plates after construction is finished. The net rack plate type rotating support is high in capacity of bearing horizontal loads; weld joints between the stiffening plates and the support ball are not welded, the ball can rotate by the support without dropping, so that the net rack plate type rotating support is convenient to construct, and the construction efficiency is improved; and the strength and stiffness of the support are high, so that the net rack plate type rotating support is suitable for a large-load and large-span net rack structure.

Description

technical field [0001] The invention relates to a building support, in particular to a network frame plate type rotating support used for connecting the network frame of a large-span reticulated shell structure building with embedded parts. Background technique [0002] At present, the common grid plate bearings used in reticulated shell structures are usually connected by three longitudinal stiffeners and bolted balls or welded balls. figure 1 As shown, the lower ends of the three stiffening plates are welded to the base, and the upper ends of the three stiffening plates embrace the lower parts of the bolt balls or welding balls from different angles and then are fixedly connected by welding. The bolt ball is forged by 45# steel blank steel ball. The welded ball is a hollow ball welded by two hemispheres. There are more than one bolt hole on the bolt ball, which is used to connect with the reticulated shell structure rods through bolts; the welded ball Then it is welded wi...

AI Technical Summary

Problems solved by technology

The deficiencies of the common grid plate bearings are at least as follows: First, because the length of the connecting weld between the ball and the stiffening plate is short, the horizontal stiffness is small, and the ability to withstand horizontal loads is not strong; the second is that the ball and the stiffening plate The plate is always welded and fixed, and cannot be rotated, which brings inconvenience to the construction; third, 2-4 ordinary bolts are usually used to bear the tension, so it can only be used for small and medium-span grid structure buildings with simple structural forms, not suitable for tension or horizontal Large-load, long-span grid structure buildings with relatively large shear force
