However, in actual engineering, this kind of constraint is realized by connecting the grid member and the support with pins, and only realizes the freedom of rotation in one direction, which cannot meet the requirements of structural design; or simply design the support as a cylinder A sleeve composed of a cylinder, since the diameter of the cylinder is smaller than the inner diameter of the cylinder, it can have a slight angular displacement and horizontal displacement in the sleeve. The force transmission method of this support structure is not clear, and can only achieve Partial effect of the movable hinge bearing, so it can only be counted as a "pseudo" movable hinge bearing
The above-mentioned supports often cause secondary internal forces of the grid, and at the same time lead to unreasonable stress on the supports themselves, resulting in a serious discrepancy between the structural design and the actual situation

Embodiment Construction
[0024] The following will combine Figure 1 to Figure 16 The present invention is described further:
[0025] Such as figure 1 As shown, the upper bearing seat 1 is in clearance fit with the first steel shaft 2, and the bolts 5 are used to fix the two to prevent relative sliding between the first steel shaft 2 and the upper bearing seat 1. The first steel shaft 2 is connected with the middle bearing seat 3 through the upper angular contact ball bearing, and the end cover 4 is fixed outside the middle bearing seat 3 with six screws to limit the outer ring of the upper angular contact ball bearing and the middle bearing seat 3 The two ends of the first steel shaft 2 are processed as screws, and the nuts 12 are screwed on to limit the relative sliding of the inner ring of the upper angular contact ball bearing 8 and the first steel shaft 2. Through the above structure, the relative rotation between the upper bearing seat 1 and the middle bearing seat 3 is realized. The middle ...

The invention relates to a movable hinged support for supporting net, which can serve as a connecting element between a supporting net house cover and a pillar. The hinged support is integrated in series vertically and movably from top to bottom through a steel shaft, an angular contact ball bearing and a middle bearing block, thereby realizing the aim of universal rolling. The bottom of the hinged support adopts the form of a roller and a guide groove to enable the support to slide in the horizontal direction. The support can be completely released from three directional restraints on the rotational degree of freedom and one directional restraint on the horizontal degree of freedom, thereby effectively eliminating bent moment and shearing force between the supporting net house cover and the end of the pillar and defining the force transmission path between the supporting net house cover and the end of the pillar with simple manufacture technique.
Description
technical field [0001] The invention relates to a movable hinge support suitable for a network frame, which can be used as a connecting member for a network frame roof and a column. Background technique [0002] In the building structure, according to the deformation requirements of the grid due to the temperature load, wind load or earthquake load, the side support of the grid roof is often designed as a movable hinge support. However, in actual engineering, this kind of constraint is realized by connecting the grid member and the support with pins, and only realizes the freedom of rotation in one direction, which cannot meet the requirements of structural design; or simply design the support as a cylinder A sleeve composed of a cylinder, since the diameter of the cylinder is smaller than the inner diameter of the cylinder, it can have a slight angular displacement and horizontal displacement in the sleeve. The force transmission method of this support structure is not clea...
