Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and more specifically, to a constrained hinge support suitable for rotatable spherical nodes of a space frame. Background Technology

[0002] my country's industrial construction has developed rapidly, with the widespread application of statically indeterminate reticulated shell structures, enabling the enclosure of large-span industrial buildings. Based on node type, these can be divided into welded spherical node reticulated shells and bolted spherical node reticulated shells. The construction methods differ for different types of reticulated shell structures. Large-span welded spherical reticulated shells often utilize a single-sided jacking construction process, while large-span bolted spherical reticulated shells employ a single-sided lifting process for the initial span installation. A common feature of both processes is that the spherical nodes at the supports are rotatable hinged supports. Therefore, it is necessary to invent a support that allows the spherical nodes to rotate within the support while simultaneously restricting their displacement, thus providing effective constraint and resisting external forces. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a constrained hinge support suitable for rotatable spherical nodes of a space frame is provided, which enables the spherical nodes of the space frame to rotate freely while effectively restricting external forces in all directions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A constrained hinge support for a rotatable ball node of a space frame includes a base plate. A vertical rib plate is fixedly provided at the upper end of the base plate. The included angle between adjacent vertical rib plates is 90°. A stiffening rib plate is fixedly provided between adjacent vertical rib plates. A threaded hole is provided through the stiffening rib plate. A hinge bolt is threadedly connected to the threaded hole. An adjusting nut is threadedly connected to the lower end of the hinge bolt.

[0006] It also includes a cross-shaped steel wire rope, with the four ends of the steel wire rope connected to the reserved holes at the top of the four hinge bolts.

[0007] Preferably, a steel pad is provided at the lower end of the stiffening rib, and the side of the adjusting nut near the stiffening rib contacts the steel pad.

[0008] Preferably, the stiffening rib is triangular and is arranged parallel to the base plate.

[0009] Preferably, the wire rope is connected to the hinge bolt by a wire rope clamp.

[0010] Preferably, it also includes a ball-node mesh shell, which is disposed at the upper end of the vertical rib plate of the support, and the wire rope passes through the upper side of the ball-node mesh shell.

[0011] Preferably, it also includes an embedded plate, which is connected to the base plate by bolts.

[0012] The beneficial effects of this invention compared to the prior art are as follows:

[0013] This invention increases the rigidity and load-bearing capacity of the original support by setting stiffening ribs between the vertical ribs of adjacent supports; the wire rope is closely fitted to the spherical node shell with a large contact surface, effectively providing resistance in all directions and ensuring the safety of the spherical node shell during rotation; the wire rope is made of flexible material, reducing damage to the spherical node shell during rotation; the tension and relaxation of the wire rope are achieved through the hinge bolt, with a large adjustment range, suitable for spherical nodes of different diameters; the wire rope, steel pad, hinge bolt, nut, etc. of the constraint hinge support can be reused, generating good economic benefits; this invention is based on the modification of the original spherical node support, without the need to replace the spherical node support, making construction convenient and reliable.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 , Figure 2 As shown, a constrained hinge support suitable for rotatable ball nodes of a space frame is based on the modification of the original space shell structure, such as welded ball node space shell and bolted ball node space shell. It includes a base plate 1, with a support vertical rib plate 2 fixedly installed on the upper end of the base plate 1. The included angle between adjacent support vertical rib plates 2 is 90°, and the ball node space shell 10 is installed on the upper end of the support vertical rib plate 2.

[0020] Stiffening ribs 3 are fixedly installed between adjacent vertical ribs 2 of the support. The stiffening ribs 3 are located in the middle of the vertical ribs 2 of the support, and there are 4 stiffening ribs 3. The thickness of the stiffening ribs 3 is the same as the design thickness of the vertical ribs of the support. The stiffening ribs 3 are triangular and parallel to the base plate 1. The stiffening ribs have a single-sided V-shaped bevel and are welded to the vertical ribs 2 of the support with equal strength and penetration.

[0021] A threaded hole 4 is provided through the stiffening rib 3, and a hinge bolt 5 is internally threaded into the threaded hole 4. The hinge bolt is an M20 fully threaded bolt, and an adjusting nut 6 is threadedly connected to the lower end of the hinge bolt 5. A steel pad 8 is provided at the lower end of the stiffening rib 3, and the side of the adjusting nut 6 closest to the stiffening rib 3 contacts the steel pad 8. The hinge bolt 5 can be moved up and down by adjusting the adjusting nut 6.

[0022] The steel wire rope 7 consists of two 20mm 1770MP fiber core steel wire ropes arranged in a cross shape. The steel wire rope 7 wraps around the upper surface of the ball joint, and after passing through the pre-drilled holes in the hinge bolts 5 at its four ends, it is bent and secured using steel wire rope clips 9, and then fitted onto the hinge bolts 5. The tension and relaxation of the steel wire rope 7 are adjusted using the hinge bolts 5. The lower part of the steel wire rope 7 tightens towards the center of the ball joint shell 10, increasing the contact area between the steel wire rope 7 and the ball joint shell 10, effectively restraining external forces in all directions on the ball joint shell 10.

[0023] It also includes a pre-embedded plate 11, and the base plate 1 is fixed on the pre-embedded plate 11 by bolts.
