Embodiment 1

[0026] Embodiment one sees figure 1 2. This kind of steel structure universal support is formed by the flexible connection of the bottom plate and the gusset plate. There are 20 bolt holes 12 distributed on the four sides of the bottom plate 1. The bolt holes can be round holes or oblong holes, and are connected with the concrete The pre-embedded anchor rod 3 is fixedly connected, and there is an upwardly convex spherical crown hinge 11 in the center of the base plate. The height of the spherical crown hinge is less than 1 / 2 spherical radius, and its top is flat, which is relatively easy to process.

[0027] Six ring plates 2 are distributed in a circular interval between the bolt hole of the bottom plate and the spherical crown hinge. The upper gusset plate 6 is surrounded by the outer edge, and the radian of the outer edge of the gusset plate is similar to that of the inner arc surface of the ring plate. There is a gap between the inner arc surface of the ring plate 2 and th...

Abstract

The steel structure gimbal consists of bottom board and node board connected movably. The bottom board has screw holes in the edges for connection with the pre-buried anchor shaft in the structure, one upward convex spherical crown hinge in the center, three or more ring boards between the screw holes and the spherical crown hinge and possessing bottom connected to the bottom board and inner arc surface to cover the node board on the spherical crown hinge with some interval in between. The node board has notch in the position corresponding to the spherical crown hinge of the bottom and in the depth smaller than the height of the spherical crown hinge. The node board is connected to the bottom board through anchor bolts with elastomer. The present invention has easy manufacture, low cost, and flexible rotation, and is suitable for various kinds of earthquake-proof building structure.

Description

(1) Technical field [0001] The invention relates to a movable hinge support of a building structure node, in particular to a steel structure universal support. (2) Background technology [0002] In building structures, traditional steel structure universal bearings include basin bearings and ball bearings. Both are formed by the flexible connection of the bottom plate and the gusset plate, and the four sides of the bottom plate are distributed with bolt holes, and are fixedly connected with the pre-embedded anchor rods in the concrete. After the four anchor bolts are installed on the support gusset plate, the support node cannot rotate well, so that the pull-out resistance of the support is weak, and it cannot rotate at the same time after being subjected to upward pulling force. Due to the spherical contact between the bottom plate and the gusset plate, the manufacturing requirements are high, finishing machining is required, and the cost is expensive, so it is not suitabl...
