Description

Technical Field

[0001] This utility model relates to the field of corner column technology, specifically a corner column for frame connection. Background Technology

[0002] In construction sites, a corner column typically refers to a vertical load-bearing component located at the structural corners of a building (such as exterior wall corners or floor slab junctions). Its primary function is to enhance structural stability, transfer loads, and resist lateral forces (such as wind and earthquakes). As part of the structural system, a corner column bears the vertical loads transmitted from floor slabs, beams, and walls, transferring them to the foundation. In complex floor plans, corner columns serve as crucial nodes for structural positioning, ensuring accurate connections between components in all directions.

[0003] In construction sites, the beams and columns of a frame are welded on-site. Due to the inability to accurately position the components during welding, the welding precision is low. During assembly, the cumulative errors easily lead to poor assembly, and on-site welding is inefficient, potentially impacting project progress. Therefore, integrating columns and connectors into modular corner columns, and then assembling the frame using these corner columns and beams, achieves rapid frame connection and significantly improves assembly precision. However, existing corner columns are either too complex, making processing and assembly difficult, or too simple, only allowing beam connections in two directions, failing to meet the needs of different frame connections. Therefore, improvements are urgently needed. Utility Model Content

[0006] In a further preferred embodiment, the first corner connector includes a first base plate, on which at least one first connecting plate is provided, and the first connecting hole is provided on the first connecting plate, thereby achieving connection with the crossbeam through the first connecting plate and the first connecting hole thereon.

[0007] Preferably, the structure of the second corner connector is the same as that of the first corner connector. The second corner connector includes a second base plate, and at least one second connecting plate is provided on the second base plate. The second connecting hole is provided on the second connecting plate, and the connection with the crossbeam is achieved through the second connecting plate and the second connecting hole thereon.

The first connecting plates 32 and the second connecting plates 42 have the same structure.

[0031] In this embodiment, by providing two first connecting plates 32 on each first corner connector 3 and two second connecting plates 42 on each second corner connector 3, the firmness of the beam connected by the first corner connector 3 and the second corner connector 4 can be ensured, and the structural firmness and strength of the overall frame connected by the corner columns can be guaranteed.

[0032] In this embodiment, based on the above embodiments, in another embodiment of this application, the first connecting plate 32 and the second connecting plate 42 have the same structure, which facilitates the processing and installation of the first connecting plate 32 and the second connecting plate 42. No excessive design or methods are required; a single structure can be directly manufactured.

[0035] In this embodiment, every two opposing first corner connectors 3 and their corresponding two connecting blocks 2 are connected vertically by two screws 5. This ensures that the two opposing first corner connectors 3 and their corresponding connecting blocks 2 are on the same horizontal plane. No separate measurement or calibration is required before installation; only the horizontality of the holes needs to be ensured during drilling. This reduces the installation difficulty of the first corner connectors 3 and the corresponding connected crossbeams. No calibration of the crossbeams is required, ensuring that the installed crossbeams meet the requirements, ultimately guaranteeing the overall aesthetics and stability of the connected frame. Similarly, every two opposing second corner connectors 4 and their corresponding two connecting blocks 2 are connected vertically by two screws 5. This ensures that the two opposing second corner connectors 4 and their corresponding connecting blocks 2 are on the same horizontal plane. No separate measurement or calibration is required before installation; only the horizontality of the holes needs to be ensured during drilling. This reduces the installation difficulty of the second corner connectors 4 and the corresponding connected crossbeams. No calibration of the crossbeams is required, ensuring that the installed crossbeams meet the requirements, ultimately guaranteeing the overall aesthetics and stability of the connected frame.

[0036] Please refer to Figure 4 As shown, based on the above embodiments, in another embodiment of this application, each screw 5 is provided with a nut 6 and a flat washer 7 at both ends, and a spring washer 8 is sandwiched between the nut 6 and the flat washer 7.
