Description

Technical Field

[0001] This utility model relates to the field of curtain wall installation, and in particular to a prefabricated, weld-free curtain wall column connection structure. Background Technology

[0002] Glass curtain walls consist of panels and a keel system. Horizontal keels and columns are connected by bolts. The columns are connected to the main structure by bolts, embedded parts, and other components to form the keel system. The glass panels are then fixed to the keel system using pressure plates, support plates, bolts, screws, and structural adhesive, ultimately forming the glass curtain wall. Embedded parts are divided into channel-type embedded parts and plate-type embedded parts. Plate-type embedded parts require welding angle brackets to connect the columns to the main structure. Welding is time-consuming, labor-intensive, and prone to damaging the glass panels, resulting in poor reliability. Channel-type embedded parts are assembled and connected to the columns using T-bolts. For example, a novel glass curtain wall disclosed in Chinese utility model patent CN215253793U includes columns, channel-type embedded parts, pressure plates, and fixing plates. The columns and channel-type embedded parts are connected by fixing plates on the pressure plates. Since the fixing plates and pressure plates are integrally formed, their spacing is fixed according to the position of the channel-type embedded parts, making it difficult to adjust and unable to adapt to errors in the civil engineering structure and deformation of the main structure. Utility Model Content

[0003] The purpose of this invention is to provide a prefabricated, weld-free curtain wall column connection structure. All fixing components of this invention are independently assembled without welding, allowing for movement and size replacement, thus adapting to errors in the civil engineering structure and deformation of the main structure, resulting in excellent practicality and reliability.

[0004] The technical solution of this utility model is as follows: A prefabricated, weld-free curtain wall column connection structure includes columns and pre-embedded groove-type embedded parts. The pre-embedded groove-type embedded parts are pre-embedded in the bottom and top of the beam. T-shaped mounting bolts are symmetrically arranged on the pre-embedded groove-type embedded parts. The T-shaped mounting bolts of the pre-embedded groove-type embedded parts at the top of the beam are fixed with nuts to a first L-shaped transition angle steel, and there is a column installation gap between the two first L-shaped transition angle steels. The lower end of the inner cavity of the column is provided with a movable connecting sleeve core, and the two sides of the sleeve core are provided with second L-shaped transition angle steels. The upper end of the column is located within the column installation gap and is fixed with the first L-shaped transition angle steels on both sides. The lower end of the column is fixedly connected to the T-shaped mounting bolts on the pre-embedded groove-type embedded parts at the bottom of the beam through the second L-shaped transition angle steel on the sleeve core.

[0005] In the above-mentioned prefabricated weldless curtain wall column connection structure, the pre-embedded groove type embedded part has rotating insert cavities on both sides that are adapted to the T-shaped mounting bolt nuts, and the rotating insert cavity is provided with an insertion port adapted to the T-shaped mounting bolt nuts.

[0006] In the aforementioned prefabricated weldless curtain wall column connection structure, the bottom surface of the nut of the T-shaped mounting bolt is provided with a fitting tooth, and the inner surface of the rotating cavity is provided with a slot surrounding the insertion port, the slot being adapted to the fitting tooth.

[0007] In the aforementioned prefabricated weldless curtain wall column connection structure, the depth of the rotating cavity is greater than the thickness of the T-shaped mounting bolt nut.

[0008] In the aforementioned prefabricated weldless curtain wall column connection structure, the upper end of the column is fixed to the first L-shaped transition angle steel on both sides by multiple horizontally assembled through bolts.

[0009] In the aforementioned prefabricated weldless curtain wall column connection structure, the core includes a frame-shaped main body, and each of the four sides of the frame-shaped main body is provided with a limiting side plate that fits against the inner cavity wall of the column. One end of the second L-shaped transition angle steel is inserted into the inner cavity of the frame-shaped main body and connected by multiple countersunk screws.

[0010] In the aforementioned prefabricated weldless curtain wall column connection structure, the inner cavity of the column is provided with a guide strip, and the side wall of the frame-shaped main body and the limiting side plate on the same side form a guide groove that fits with the guide strip.

[0011] In the aforementioned prefabricated weldless curtain wall column connection structure, multiple countersunk screws are provided and arranged horizontally.

[0012] Compared with the prior art, the present invention first inserts and fixes two second L-shaped transition angle steels into the sleeve core during installation. The sleeve core is then inserted from the bottom of the column. Subsequently, T-shaped mounting bolts are installed and engaged in the pre-embedded grooves at the bottom and top of the beam. Two first L-shaped transition angle steels are then fixed to the T-shaped mounting bolts at the top of the beam with nuts. Finally, the upper end of the column is placed into the column installation gap and fixed to the first L-shaped transition angle steels with through bolts and nuts. The lower end of the column is connected to the T-shaped mounting bolts of the pre-embedded grooves at the bottom of the beam via the second L-shaped transition angle steels on the sleeve core. The connection is as follows: the first L-shaped transition angle steel and the second L-shaped transition angle steel are both assembled with bolts, and the sleeve core can move relative to the column. Each bolt can be left loose during assembly, allowing for a small range of movement, so that the column is not completely fixed. This facilitates the adjustment of parameters such as planar position, vertical position, and verticality. After adjustment, the bolts are tightened to fix it completely. All fixing components of this utility model are assembled independently without welding, and can be moved and sized to adapt to errors in civil engineering structures and deformation of the main structure, thus having excellent practicality and reliability.

The bolt 3 is connected; the pre-embedded groove type embedded part 2 has rotating cavities 8 on both sides that are adapted to the nuts of the T-shaped mounting bolt 3, and the rotating cavity 8 has a socket 9 adapted to the nuts of the T-shaped mounting bolt 3. The nuts of the T-shaped mounting bolt are inserted into the socket and rotated 90° to engage with the rotating cavity; the bottom surface of the nut of the T-shaped mounting bolt 3 is machined with fitting teeth 10, and the inner surface of the rotating cavity 8 is machined with a groove 11 around the socket 9. The groove 11 is adapted to the fitting teeth 10, and the connection is achieved through... The engagement of the slot and the fitting teeth enhances the fixing reliability of the T-shaped mounting bolt; the depth of the rotating cavity 8 is greater than the thickness of the nut of the T-shaped mounting bolt 3, ensuring sufficient space for the slot and the fitting teeth to engage; the inner side of the nut of the T-shaped mounting bolt 3 has a 40×40×3mm square hot-dip galvanized washer, effectively preventing the nut from loosening; the sleeve 6 includes a frame-shaped body 12, and the four sides of the frame-shaped body 12 are integrally formed with limiting side plates 13 that fit against the inner wall of the column 1, for lateral positioning within the column; one end of the second L-shaped transition angle steel 7 is inserted into the inner cavity of the frame-shaped body 12 and connected by six M8X35mm countersunk screws on both sides, and the other end is located on the outer side of the column; the inner cavity of the column 1 is integrally formed with a guide strip 14, and the side wall of the frame-shaped body 12 and the limiting side plate 13 on the same side form a guide groove 15 that fits with the guide strip 14, improving the reliability of the sleeve when moving within the column; three countersunk screws are provided and arranged laterally.

[0020] Working principle: During installation, firstly, two second L-shaped transition angle steels 7 are inserted and fixed into the sleeve 6.

Subsequently, T-shaped mounting bolts 3 are installed in the pre-embedded groove-type embedded parts 2 at the bottom and top of the beam. After rotating 90°, the engaging teeth and slots mesh. Two first L-shaped transition angle steels 4 are fixed to the T-shaped mounting bolts 3 at the top of the beam with nuts. Finally, the upper end of the column 1 is placed into the column installation gap 2 and fixed to the first L-shaped transition angle steels 4 with through bolts and nuts. The lower end of the column 1 is connected to the T-shaped mounting bolts 3 of the pre-embedded groove-type embedded part 2 at the bottom of the beam via the second L-shaped transition angle steels 7 on the sleeve 6. Both the first L-shaped transition angle steels 4 and the second L-shaped transition angle steels 7 are assembled with bolts, while the sleeve 6 can be... Compared to the movable column 1, the bolts can be left loose during assembly, allowing for a small range of movement and placing the column 1 in a partially fixed state. This facilitates adjustments to parameters such as planar position, vertical position, and verticality. After adjustment, the bolts are tightened for complete fixation. This invention can absorb errors in civil engineering structures and deformations in the main structure. Furthermore, the weld-free connection structure effectively prevents fire accidents during installation, resolving the contradiction between the aesthetics and functionality of glass curtain walls. It promotes standardized construction and strong adaptability. Moreover, this invention enables standardized production of glass curtain wall system components, reducing material and mold costs, facilitating mass production, lowering construction difficulty, improving work efficiency, and reducing project costs.
