Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to the corner connection structure of the columns in the curtain wall. Background Technology

[0002] With the development of the construction industry, curtain wall systems are increasingly widely used in super high-rise buildings, and innovative curtain wall structures are becoming more and more common, while aesthetic requirements for exterior curtain walls are becoming more stringent. In exterior curtain wall systems, the transition points between the top and bottom horizontal beams connecting the curtain wall unit blocks are critical nodes in curtain wall installation and also a key aesthetic point. The rationality of the horizontal beam transition structure design affects construction efficiency, project quality, and aesthetic appearance. Traditional curtain wall transition structures mainly involve connecting the central column to the top and bottom horizontal beams via aluminum alloy or steel angle brackets. While this connection structure generally meets the connection requirements, it has the following technical problems: 1. The angle brackets are exposed at the connection points between the central column and the top or bottom horizontal beam, resulting in uneven connection marks that affect the aesthetic appearance of the curtain wall; 2. The angle bracket structure has poor strength and is prone to cracking, affecting the structural quality of the curtain wall; 3. Installation speed is slow, and construction efficiency is low. Therefore, new technologies are needed to control project quality and construction efficiency, as well as improve the aesthetic appearance of the curtain wall. Utility Model Content

[0003] The purpose of this utility model is to address the drawbacks of using corner brackets to connect the top and bottom horizontal beams of the curtain wall columns in existing technologies, and to provide a corner connection structure for the curtain wall columns to solve the following technical problems: (1) the corner bracket connection part is exposed, and the unevenness affects the aesthetics; (2) the operation is complicated and the construction efficiency is low; (3) the corner bracket has low strength, which affects the structural quality.

[0004] The objective of this utility model can be achieved. The corner connection structure for the central column of this utility model includes a central column, a top horizontal beam, and a bottom horizontal beam. The feature of this corner connection structure is: a concealed upper plug is provided, the core of which is inserted into the top of the central column, and the insert of which is horizontally angled and inserted into the ends of the top horizontal beams on both sides; a concealed lower plug is provided, the core of which is inserted into the bottom of the central column, and the insert of which is horizontally angled and inserted into the ends of the bottom horizontal beams on both sides. The central column is connected to the top horizontal beam via the concealed upper plug, and to the bottom horizontal beam via the concealed lower plug, thus forming the corner connection structure for the central column of the curtain wall.

[0005] This utility model relates to a corner connection structure for curtain wall columns. The concealed upper plug includes an insert and an upper core. The insert is formed by diagonally welding a front insert plate and a folding insert plate at a 90° angle to each other. The upper core is welded to the lower surface of the front insert plate and the folding insert plate. The upper core is inserted into the upper cavity of the central column. The front insert plate and the folding insert plate are respectively inserted at angles into the end cavities of the top horizontal beams on both sides, forming a corner structure for the top horizontal beams. The concealed lower plug includes a lower insert, a right-angle outer insert plate, and a right-angle inner insert plate. The right-angle outer insert plate is formed by welding two small insert plates of the same structure at 90° perpendicularly. The right-angle inner insert plate is formed by welding two large insert plates of the same structure at 90° perpendicularly. The surfaces of the right-angle outer insert plate and the right-angle inner insert plate are on the same plane. The right-angle outer insert plate is located outside the right-angle inner insert plate. There is a connection gap between the right-angle outer insert plate and the right-angle inner insert plate. The lower insert is welded to the upper plane formed by the right-angle outer insert plate and the right-angle inner insert plate. The lower insert is inserted into the lower end cavity of the central column. The bottom crossbeam end cavity on the same side of the right-angle outer insert plate and the right-angle inner insert plate is inserted into the bottom crossbeam, forming a bottom crossbeam corner structure.

[0006] The present invention relates to a corner connection structure for a central column in a curtain wall. The concealed upper plug 5 is connected and fixed to the central column by bolts, washers, spring washers and nuts. The plug of the concealed upper plug is connected and fixed to the top beam by screws. The concealed lower plug is connected and fixed to the central column by bolts, washers, spring washers and nuts. The plug of the concealed lower plug is connected and fixed to the bottom beam by screws.

[0007] The corner connection structure of the curtain wall column of this utility model, wherein the upper plug core, front plug plate and folding plug plate of the hidden upper plug, and the lower plug core, right-angle outer plug plate and right-angle inner plug plate of the hidden lower plug are all hollow bodies formed by bending and welding of sheet metal.

[0008] In this utility model, the corner connection structure of the curtain wall column is described, wherein the welding angle between the front insert plate and the folding insert plate of the concealed upper plug is 45°, the welding angle between the two small insert plates of the right-angle outer insert plate of the concealed lower plug is 45°, and the welding angle between the right-angle inner insert plate of the concealed lower plug is 45°.

[0009] The present invention relates to a corner connection structure for curtain wall columns, wherein the inner cavity of the central column is substantially similar in shape and size to the outer shape and size of the upper and lower inserts, forming a dynamic mating insertion structure.

[0010] The corner connection structure of the curtain wall column of this utility model is a standard component, wherein the hidden upper plug and the hidden lower plug are standard components.

[0011] The difference between this utility model's curtain wall mound corner connection structure and existing technologies lies in the inclusion of a concealed upper plug and a concealed lower plug, each equipped with a core and a insert. The core of the concealed upper plug is inserted into the top of the mound, while the insert is horizontally angled and inserted into the ends of the top horizontal beams on both sides. The core of the concealed lower plug is inserted into the bottom of the mound, while the insert is horizontally angled and inserted into the ends of the bottom horizontal beams on both sides. The mound is connected to the top and bottom horizontal beams via the concealed upper and lower plugs, forming the curtain wall mound corner connection structure. This curtain wall mound corner connection structure is rationally designed and solves the technical problems encountered with traditional corner bracket connections for curtain wall corners. The corner connection structure of the central column in the curtain wall using this utility model forms an integral whole with the corner connection of the top and bottom horizontal beams and the connection between the top and bottom horizontal beams and the central column. The structure is stable and the force is balanced. The upper and lower plugs are hidden in the column and the cavity of the horizontal beam, with no connection marks on the outside, resulting in a good aesthetic effect. The standard parts have high strength, fast installation speed, and high quality.
