Description

Technical Field

[0002] In recent years, with the continuous development of architectural design software and the advancement of steel structure processing technology, various types of special-shaped grid shells, bionic grid shells and other steel structures have frequently appeared in large public buildings such as stadiums, exhibition halls, and shopping malls. In order to meet the building functions and appearance, these types of steel structures have no specific rules for the spatial angles between the rods. At this time, if two or more rods are directly welded, one rod must be connected as the main rod. If the angle at the intersection of the rods is small, the rods must meet the construction and processing and installation requirements, which will lead to a chaotic overlap sequence of the rods at the intersection, complex nodes that are not suitable for processing, and more welds at the connection, which will weaken the cross-section, increase assembly errors, affect structural safety, and increase on-site welding workload and construction costs.

The top of each stiffening plate 150 is connected to the top cover 120. The bottom of the inner ring plate 130 is connected to the bottom cover 110 and each bottom fan ring plate 170. The top of the inner ring plate 130 is connected to the top cover 120. The bottom of the outer ring plate 140 is connected to each bottom fan ring plate 170, and the top of the outer ring plate 140 is connected to the top cover 120. The stiffening plates 150 correspond one-to-one with the additional box-shaped rods 200. The centerline of each additional box-shaped rod 200 passes through a corresponding stiffening plate 150 and intersects with the central axis of the central node 100. In this embodiment, the angle between the centerline of each additional box-shaped rod 200 and the central axis of the central node 100 is 40 degrees. Each additional box-shaped rod 200 is composed of a top plate, a bottom plate, and two side plates that are connected together. One end of each additional box-shaped member 200 is connected to the outer wall of the outer ring plate 140, and the top plate of each additional box-shaped member 200 is connected to the top cover 120 of the central node 100. The bottom of each additional box-shaped member 200 is connected to the outer wall of the outer ring plate 140, and the connection is reinforced by two bottom ribs 160. The top and bottom of the additional box-shaped member 200 are connected to additional ear plates 220 extending along their length.

The top plate, bottom plate, and two side plates of each overlapped box-shaped member 210 are respectively connected to the top plate, bottom plate, and two side plates of the additional box-shaped member 200. After the additional box-shaped member 200 is connected to the overlapped box-shaped member 210, the additional ear plates 220 and the corresponding overlapping ear plates 230 can be removed.

[0032] The box-type rod cross-rigid joint provided in the embodiment of the present application includes a hollow central node 100 with a conical top and a cylindrical bottom and overlapped box-type rods 210 arranged at intervals along the circumference of the central node 100. The central node 100 is an inner and outer double-layer annular box structure composed of a bottom cover 110, nine bottom fan ring plates 170, a top cover 120, an inner ring plate 130 and an outer ring plate 140 sleeved on the outside of the inner ring plate 130.

The positive stress of the overlapped box-type member 210 is transmitted to the node top cover 120 and the outer ring plate 140 through the top plate and the bottom plate of the additional box-type member 200 respectively, and then further transmitted to the node stiffening plate 150 and the bottom cover 110, and then transmitted to the inner ring plate 130 to achieve stress dispersion, thereby achieving the rigid connection effect of the node and improving the overall structural strength and stiffness of the node.

[0033] The box-type cross-joint rigid connection provided in the embodiment of the present application is welded from the inside to the outside in the factory, with the inner ring plate 130, stiffening plate 150, outer ring plate 140, top cover 120, bottom cover 110, bottom fan ring plate 170, and each additional box-type member 200 being welded. The on-site splicing is an equal-strength splicing of the additional box-type member 200 and the overlapped box-type member 210, thereby improving the convenience of on-site welding construction operations, effectively reducing the construction workload and saving installation costs while fully meeting the requirements of the architectural space modeling. Among them, the center lines of each overlapped box-type member 210 and the additional box-type member 200 pass through a corresponding stiffening plate 150 and then intersect at the central axis of the central node 100, which can ensure the balance of the node's force center and improve the stability of the connection between each box-type member and the central node 100.

[0034] In addition, the bottom of each additional box-shaped member 200 is connected to the outer wall of the outer ring plate 140 via two bottom ribs 160, further enhancing the structural strength and stability of the connection between the additional box-shaped member 200 and the outer ring plate 140. Each additional box-shaped member 200 is internally provided with a transverse rib 250, the four sides of which are connected to the inner walls of the four sides of the additional box-shaped member 200. The additional lugs 220 are arranged across the transverse ribs 250, enhancing the structural strength of the additional box-shaped member 200. The additional box-shaped member 200 and the overlapped box-shaped member 210 are connected at the top and bottom, respectively, with additional lugs 220 and overlapping lugs 230 extending along their lengths. The additional lugs 220 and overlapping lugs 230 are connected via a temporary connecting plate 240, facilitating lifting and ensuring the precision of the strong connection between the additional box-shaped member 200 and the overlapped box-shaped member 210.

[0035] An embodiment of the present application further provides a building, which includes the above-mentioned box-type cross-rigid joint.

[0036] In other optional embodiments, the thickness of the stiffening plate 150 may also be equal to the thickness of the largest one among the top plate, bottom plate and side plates of the additional box-shaped rod 200 .

[0037] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
