Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall technology, and in particular to a connection structure between a steel beam and a column. Background Technology

[0002] In modern architecture, with the increasing pursuit of spatial scale and indoor-outdoor transparency, the height and size of glass curtain walls are growing larger and larger. If aluminum profile keels are continued to be used, the outer dimensions of the keel will increase dramatically with the increase in curtain wall height and size due to structural load requirements, affecting both the visual effect and occupying interior space. With the advancement of complex cold bending forming technology for thin steel plates, the emergence of refined steel keels has effectively solved the dual requirements of visual scale and structural load-bearing capacity. However, the connection problem between the steel beams and columns needs to be solved.

[0003] The connection structure between the steel beam and the column is an important connection structure. On the one hand, from the perspective of structural stress, it must be able to transmit force accurately and reliably. On the other hand, from the perspective of engineering implementation, the on-site installation operation of this connection structure should be simplified as much as possible. It is best to adopt a modular connection structure and prefabricate and assemble it in the factory, so that only simple operations such as snap-fit ​​are required on site. Therefore, it is necessary to coordinate and solve problems such as reliable connection stress, stable installation quality and high installation efficiency.

[0004] Currently, there are two main construction methods for connecting steel beams and columns: (1) Steel beams and columns are connected by special steel connectors using bolts, screws, and other mechanical fastening methods. Although the connection is firm and reliable, it is mostly done by assembling and installing individual parts on site. The assembly and fastening operations on site are cumbersome, resulting in a large workload and low installation efficiency. It is mainly suitable for applications with small project areas. (2) Steel beams and columns are connected by aluminum core body + spring pin. On the one hand, aluminum has strong plasticity and is easy to mold and form, making it highly adaptable to changes in curtain wall structure. On the other hand, the aluminum core body + spring pin connection does not require fastening operations on site. It only needs to be snapped into place, resulting in low labor intensity and high efficiency in installation. However, the current practice of applying an isolation coating or attaching an isolation sleeve to the outer surface of the aluminum core body to solve the problem of steel-aluminum contact corrosion is unreliable and time-consuming. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for convenient and reliable connection between steel beams and columns during glass curtain wall installation, addressing the shortcomings of the aforementioned background technology.

[0006] To achieve the above objectives, this utility model provides a connection structure between a steel beam and a column, including a beam, a column, and a core assembly.

[0007] The column is provided with mounting holes, and the column is connected to the crossbeam through the core assembly. The crossbeam is also connected to the glass panel.

[0008] The sleeve assembly includes a sleeve body, a spring pin, and a separating pin. The sleeve body is provided with a spring pin mounting groove and a separating pin mounting groove. The spring pin mounting groove is used to install the spring pin, and the separating pin mounting groove is used to install the separating pin. The spring pin matches the mounting hole, and the separating pin protrudes from the outer surface of the sleeve body and contacts the inner surface of the crossbeam to isolate the outer surface of the sleeve body from the inner surface of the crossbeam.

[0009] Furthermore, the isolation pin is configured as a three-section structure, including an isolation pin shaft in the middle and tapered plugs at both ends. The large-diameter section of the tapered plug is interference-fitted with the isolation pin mounting groove, the small-diameter section of the tapered plug is clearance-fitted with the isolation pin mounting groove, and the isolation pin shaft is clearance-fitted with the isolation pin mounting groove.

[0010] Furthermore, the conical plug is made of rigid plastic, and the isolation pin is made of rigid non-metallic material.

[0011] Furthermore, both ends of the isolation pin are provided with a stepped-back shaft section, and the small-diameter section of the tapered plug is provided with a hole to accommodate the stepped-back shaft section, with the two fitting together with a clearance.

[0012] Furthermore, the spring pin mounting groove is located at each corner of the sleeve body, and the isolation pin mounting groove is located at the center of each surface of the sleeve body.

[0013] The above-mentioned solution of this utility model has the following beneficial effects:

[0014] The connection structure between the steel beam and the column provided by this utility model, based on the traditional sleeve core + spring pin, isolates the aluminum alloy sleeve core body from the steel beam by adding an isolation pin. This avoids applying an isolation coating or attaching an isolation sleeve to the outer surface of the aluminum alloy sleeve core, improving the convenience of operation and effectively solving the problem of electrochemical corrosion when steel and aluminum come into contact. Moreover, this isolation method is more stable, reliable, and durable, without increasing the on-site work content or difficulty. Most of the manufacturing can be completed in the factory.

[0015] The connection structure between the steel beam and the column provided by this utility model has isolation pins arranged around the outer surface of the sleeve body and can rotate freely after installation. This changes the previous surface-to-surface contact between the sleeve body and the beam to a line-to-surface contact, which has better adaptability to uneven stress conditions and effectively prevents the structure from jamming and the noise generated by hard friction.

[0016] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0023] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a connection structure between a steel beam and a column, including a steel beam 1, a column 2, and a core assembly. The core assembly is pre-assembled with the beam 1 in the factory. During on-site assembly, the core assembly and the beam 1 function as a single unit to accurately and reliably transfer load between the beam 1 and the column 2. From a structural perspective, the beam 1 and column 2 represent a typical T-type connection. From a manufacturing and installation perspective, on-site work should be simplified as much as possible to improve installation efficiency. The core assembly effectively meets these requirements. Firstly, the core assembly is pre-assembled with the beam 1 in the factory, requiring only simple splicing on-site, resulting in easy installation and high work efficiency. Secondly, the core assembly is easy to mold in the factory with high dimensional accuracy, ensuring a high degree of fit with the inner wall of the beam 1 and accurate and reliable force transmission. In addition, the core assembly is installed at both ends of the crossbeam 1, and after assembly, it becomes a whole, which can enhance the torsional resistance of the end section of the crossbeam 1 and effectively reduce the torsional deformation of the crossbeam 1 under the eccentric action of the self-weight of the large glass panel. It should be noted that the cross-sections of the crossbeam 1 and the column 2 are generally rectangular, and the middle of the front end plate has a recessed mounting groove to accommodate the fasteners for fixing the glass panel 3.

[0027] At the same time, such as Figure 3 As shown, the sleeve assembly includes a sleeve body 4 made of aluminum alloy. The sleeve body 4 has a spring pin mounting groove 5 and a separator pin mounting groove 6. The spring pin mounting groove 5 is used to install a spring pin 7, and the separator pin mounting groove 6 is used to install a separator pin 8. The spring pin 7 adopts a common structural form in the prior art. The spring pin 7 matches the mounting hole 9 on the side wall of the column 2. During assembly, after alignment, the insertion part of the spring pin 7 can elastically insert into the mounting hole 9, connecting the crossbeam 1 and the column 2 and transmitting force. The separator pin 8, after the sleeve body 4 is sleeved with the crossbeam 1, protrudes from the outer surface of the sleeve body 4 and contacts the inner surface of the crossbeam 1, thereby isolating the outer surface of the sleeve body 4 from the inner surface of the crossbeam 1 and preventing direct contact between them. Therefore, for steel crossbeams 1, it effectively solves the corrosion problem caused by steel-aluminum contact.

[0028] At the same time, such as Figure 4 As shown, in this embodiment, the isolation pin 8 is configured as a three-section structure, including an isolation pin shaft 10 located in the middle and tapered plugs 11 located at both ends, all three being coaxially distributed. The cross-section of the isolation pin mounting groove 6 is C-shaped (or can be considered semi-circular). The large-diameter section of the tapered plug 11 has an interference fit with the isolation pin mounting groove 6, while the small-diameter section has a clearance fit. Therefore, the tapered plug 11 can be inserted from the end of the isolation pin mounting groove 6 until the large-diameter section forms an interference fit with the isolation pin mounting groove 6, thereby limiting the isolation pin shaft 10, ensuring the accurate axial position of the isolation pin shaft 10 within the isolation pin mounting groove 6, and preventing it from dislodging from the end of the isolation pin mounting groove 6.

[0029] The conical plug 11 can be made of hard plastic, and the isolation pin 10 can be made of wear-resistant, high-strength, hard non-metallic material. During installation, one end of the conical plug 11 is installed first, using a hammer to strike the end of the conical plug 11 until it is fully inserted into the isolation pin mounting groove 6. Then, the isolation pin 10 is inserted from the other end, and finally, the other conical plug 11 is installed using the same hammering method. In a preferred embodiment, both ends of the isolation pin 10 are provided with stepped-back shaft sections, and the smaller diameter section of the conical plug 11 is correspondingly provided with holes to accommodate the stepped-back shaft sections, with a clearance fit between the two. This structure ensures that after installation, the axial position of the isolation pin 10 is fixed but it can still rotate freely around its axis. This is mainly because the cross-section of the beam 1 is asymmetrical in the vertical direction, and the beam 1 undergoes torsional deformation under the eccentric weight of the glass plate 3. These factors will lead to uneven stress distribution. Therefore, this rotating structure can effectively adapt to uneven stress conditions, preventing structural jamming and noise caused by hard friction. Correspondingly, the isolation pin 10 and the isolation pin mounting groove 6 are clearance fit.

[0030] Therefore, by using the high-strength, hard, non-metallic material of the isolation pin 10, the corrosion problem caused by the contact between steel and aluminum is well solved, and the ease of installation of the beam 1 and the column 2 is not affected.

[0031] In a preferred embodiment, the spring pin mounting groove 5 is located at each corner of the sleeve body 4, while the isolation pin mounting groove 6 is located at the center of each surface of the sleeve body 4. This allows the isolation pin 8 to better maintain the isolation between the sleeve body 4 and the crossbeam 1 after installation, making it less likely to fail during long-term use. As for the spring pin 7, it is located at multiple positions and evenly distributed relative to the sleeve body 4, corresponding to the mounting holes 9 on the side wall of the column 2, ensuring uniform force transmission and avoiding stress concentration.

[0032] When using the connection structure between the steel beam and column provided in this embodiment, the core body 4 is cut to a certain length in the factory. After fabrication, the spring pin 7 and the isolation pin 8 are installed on the core body 4. After installation, the spring pin 7 is located inside the core body 4, with only the insertion part protruding from one end face of the core body 4. The isolation pin 8 does not protrude from both end faces of the core body 4, but it protrudes from the isolation pin mounting groove 6 on the outer surface of the core body 4. The core body 4 is then inserted from both ends of the beam 1, with the protruding end of the spring pin 7 on the core body 4 facing outwards. 4. When the beam 1 is fully inserted into the inner cavity of the crossbeam 1, the two are fixed in position by limiting screw 12 (limiting screw 12 passes through the crossbeam 1 and presses against the corresponding conical plug 11); a mounting hole 9 matching the spring pin 7 is opened at the position where the crossbeam 1 is connected on the side wall of the column 2; the assembled crossbeam 1 and column 2 are transported to the installation site, the column 2 is installed first, and when the crossbeam 1 is installed, the spring pin 7 is compressed to push it from front to back along the side wall of the column 2. After reaching the position of the mounting hole 9, the insertion part of the spring pin 7 will automatically spring into the mounting hole 9 under the action of spring force, and the connection between the crossbeam 1 and the column 2 is completed.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
