A rubber plate support node

Abstract

A rubber plate support node for a space grid structure that can easily replace the rubber pad. It is an interlayer between the rubber backing plate and the top plate of the supporting surface, and an internal thread hexagonal sleeve is placed in the interlayer. The bolts are inserted into the reserved holes of the support bottom plate, rubber backing plate and interlayer top plate from top to bottom, and screwed into the hexagonal sleeve. In the barrel, after the installation and debugging of the support is completed, the hexagonal sleeve is welded to the sandwich bottom plate with side fillet welds, and the sandwich bottom plate is welded to the top plate of the support surface with side fillet welds. When replacing the rubber backing plate, set a temporary support between the bottom plate of the support and the top plate of the interlayer, unscrew the bolts from the hexagon socket, replace the rubber backing plate, and then screw in the original bolts.

Description

technical field [0001] The invention relates to a rubber plate type support node for a space grid structure, in particular to a rubber plate type support node which can easily replace rubber pads. Background technique [0002] Rubber plate bearing joints, due to their advantages of low cost, good mechanical performance and simple construction, are widely used in large and medium-sized bearings with large bearing reaction force, seismic requirements, temperature influence, large horizontal displacement and rotation requirements. Span space grid structure. At present, there are two commonly used construction methods for the support joint. One is that a rubber backing plate is added between the bottom plate of the support and the top plate of the support surface or the transition steel plate, and the anchor bolts passing through the three are connected into a whole. It must be pre-embedded in the concrete column; the other is to replace the anchor bolts of the first constructi...

Problems solved by technology

[0003] In order to overcome the disadvantage that the existing rubber plate support nodes of the space grid structure cannot realize the simple replacement of the rubber backing plate, the present invention provides a support node construction method, which not only maintains the advantages of low cost and simple construction of the existing support nodes , and has the same mechanical performance, and the more prominent advantage is that the rubber backing plate can be replaced quickly, easily and safely without suspending the function of the building and without destroying the original structural components, and the original bolts can be replaced. Repeated use can effectively reduce the engineering cost and construction period required to replace the rubber backing plate, and further promote the application range of the support node
