The ball body can be a welding ball or a bolt ball; the arrangement of the horizontal limiting ring and the vertical limiting block of the upper structure of the vertical sliding support ensures that the support node only releases the counter force of the vertical support, and can prevent the ball body and the circular tube from generating overlarge vertical displacement relative to the support bottom plate; the lower structure adopts a flat support with a transition plate, the connection structure and the calculation method are mature, and the construction is convenient. The vertical sliding support disclosed by the invention is simple in structure, reasonable in stress, safe and reliable, and eliminates a large vertical counter force at the support, so that the section and the reinforcing bars of a lower concrete structure are reduced, the structural cost is reduced, and the vertical sliding support has a good application prospect in a space grid structure.
Description
Technical Field
The patent relates to a support node of space grid structure belongs to the building steel construction field.
Background
In the space grid structure, the support node is a very important component. Under the load effect, if the upper structure is relatively fixed when being connected with the lower beam column structure or the foundation, the support has larger support counter force. Computational analysis shows that under certain conditions, the vertical support reaction force of the space grid structure under the load action is larger than the support reaction force in the horizontal direction, and if the vertical support reaction force can be eliminated, the section and the reinforcing bars of the lower concrete structure can be reduced, so that the construction cost of the structure is reduced. And current sliding support mostly is horizontal sliding support, only releases the support counter-force of horizontal direction, consequently, but provides a structure reasonable, convenient processing, passes power reliable vertical sliding support and has important value to space structure engineering design.
Disclosure of Invention
The purpose of this patent is for remedying prior art not enough, provides a vertical sliding support of space grid structure.
The technical scheme of this patent is as follows:
a vertical sliding support with a space grid structure comprises a ball body, a round pipe, a horizontal limiting ring, a ribbed plate, a vertical limiting block, a bolt, a nut, a support base plate, a transition plate and a pre-buried plate. The ball body can be a welding ball or a bolt ball; the round pipe is welded with the ball body; the horizontal limiting rings are upper and lower circular rings with the diameter slightly larger than that of the circular tube and can limit the horizontal displacement of the support joint; the number of the ribbed plates is 4-8, the ribbed plates are uniformly and annularly distributed around the horizontal limiting ring, and the vertical and horizontal right-angle edges of the ribbed plates are respectively welded with the horizontal limiting ring and the support base plate; the vertical limiting block is welded with the round pipe, so that the ball body and the round pipe are prevented from generating upward excessive displacement relative to the base plate of the support; the end part of the bolt is welded on the transition plate; the bottom plate of the support is provided with four round holes, and the diameter of each round hole is slightly larger than the outer diameter of each bolt; the size of the transition plate is larger than that of the support base plate; the size of the embedded plate is larger than that of the transition plate, the embedded plate is embedded in the top of the concrete foundation or the top of the column before installation, and the embedded plate is welded with the transition plate during installation. The position of the vertical limiting block needs to ensure that the vertical movable distance between the horizontal limiting rings is greater than the maximum displacement of the support node under the action of the conventional load combination; when the pipe contacted with the support bottom plate, vertical stopper and the horizontal spacing ring of lower part contactless, and the movable distance of pipe bottom to support bottom plate was greater than the maximum displacement of this support node under conventional load combined action to guarantee that the support bottom plate plays the effect of the downward too big displacement of restriction spheroid and pipe.
The beneficial effect of this patent:
the arrangement of the horizontal limiting ring and the vertical limiting block of the upper structure of the vertical sliding support ensures that the support node only releases the counter force of the vertical support, and can prevent the ball body and the circular tube from generating overlarge vertical displacement relative to the support bottom plate; the lower structure adopts a flat support with a transition plate, the connection structure and the calculation method are mature, and the construction is convenient; the ball body can adopt a welding ball or a bolt ball, and can be used for welding a ball joint and a bolt ball joint. This patent is under the prerequisite of guaranteeing the node safety, eliminates the great vertical counter-force of support department to reduce lower part concrete structure's cross-section and arrangement of reinforcement, reduce the structure cost, consequently have better application prospect in space grid structure.
