Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall technology, and in particular to a quick connection structure for steel beams and columns. 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 solution for quick connection between steel beams and columns during glass curtain wall installation, addressing the shortcomings of the aforementioned background technology, and solving the problem of corrosion prevention in steel-aluminum contact.

[0006] To achieve the above objectives, this utility model provides a quick connection structure for 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 and a spring pin isolator. The sleeve body is provided with a spring pin mounting groove for mounting the spring pin isolator. The spring pin isolator matches the mounting hole and can be elastically inserted into the mounting hole. The spring pin isolator also 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 spring pin isolator is configured as a four-segment structure, including a plug-in portion, a spring, an isolation support portion, and a conical portion arranged sequentially. The plug-in portion is used to insert into the mounting hole. The spring is connected between the plug-in portion and the isolation support portion. The isolation support portion is connected to the conical portion. The isolation support portion extends outward from the opening of the spring pin mounting groove to form a protrusion. The conical portion has a large-diameter section and a small-diameter section. The large-diameter section of the conical portion is interference-fitted with the spring pin mounting groove.

[0010] Furthermore, the insertion part is provided with a stepped surface.

[0011] Furthermore, the isolation support includes a cylindrical body and an eccentric body, the cylindrical body being located within the spring pin mounting groove, and the eccentric body extending to the outside of the spring pin mounting groove to form a protrusion.

[0012] Furthermore, the insertion part, the spring, and the cylindrical body are all clearance-fitted with the spring pin mounting groove.

[0013] Furthermore, the isolation support is made of non-metallic material.

[0014] Furthermore, the spring pin mounting groove is located at the center of each surface of the sleeve body.

[0015] The above-mentioned solution of this utility model has the following beneficial effects:

[0016] The quick connection structure between the steel beam and the column provided by this utility model, based on the traditional sleeve core + spring pin, improves the design by setting an integrated spring pin isolation component, which can isolate the aluminum alloy sleeve core body from the steel beam, avoiding the need to apply an isolation coating or sleeve to the outer surface of the aluminum alloy sleeve core, ensuring quick connection between the steel beam and the column on site, while effectively solving the problem of electrochemical corrosion when steel and aluminum come into contact. Moreover, this isolation method is more stable, reliable and durable.

[0017] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0024] 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.

[0025] 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.

[0026] 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.

[0027] like Figure 1 , Figure 2 As shown, this utility model provides a quick connection structure for a steel beam and 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 beam 1 function as a single unit to accurately and reliably transfer load between the beam 1 and 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 pre-assembly of the core assembly with the beam 1 in the factory necessitates 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.

[0028] At the same time, such as Figure 3 As shown, the sleeve assembly includes a sleeve body 4 made of aluminum alloy, with a spring pin mounting groove 5 for mounting a spring pin separator 6. The spring pin separator 6 matches the mounting hole 7 on the side wall of the column 2. During assembly, after alignment, the spring pin separator 6 can be elastically inserted into the mounting hole 7, connecting the crossbeam 1 to the column 2 and transmitting force. Simultaneously, after the sleeve body is fitted with the crossbeam, the spring pin separator can also protrude from the outer surface of the sleeve body 4 and contact 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. Therefore, for steel crossbeams 1, this effectively solves the corrosion problem caused by steel-aluminum contact.

[0029] At the same time, such as Figure 4As shown, in this embodiment, the spring pin isolator 6 is configured as a four-segment structure, including a plug-in portion 8, a spring 9, an isolating support portion 10, and a conical portion 11 arranged sequentially. Correspondingly, the cross-section of the spring pin mounting groove 5 is C-shaped (or considered semi-circular). The plug-in portion 8 is configured with a stepped surface. The small-diameter section of the plug-in portion 8 is used to plug into the mounting hole 7 on the column 2, while the stepped surface is used to control the depth of the plug-in portion 8 inserted into the mounting hole 7 under elastic force. The plug-in portion is fully engaged when the stepped surface contacts the side wall of the column 2. The spring 9 connects the plug-in portion 8 and the isolating support portion 10. The isolating support portion 10 is connected to the conical portion 11, and after the spring pin isolator 6 is installed in the spring pin mounting groove 5, both the isolating support portion 10 and the conical portion 11 remain within the spring pin mounting groove 5. The isolation support 10 includes a cylindrical body and an eccentric body. The eccentric body extends outward from the opening of the spring pin mounting groove 5 to form a protrusion, thereby creating contact force transmission between the outer surface of the sleeve body 4 and the inner surface of the crossbeam 1, while avoiding direct contact electrochemical corrosion. The conical part 11 also has a large-diameter section and a small-diameter section. The large-diameter section of the conical part 11 is interference-fitted with the spring pin mounting groove 5 to ensure that the relative position of the two does not change after the spring pin isolation piece 6 is installed in place, preventing it from coming out of the spring pin mounting groove 5. The small-diameter section of the conical part 11 facilitates the insertion and installation of the entire spring pin isolation piece 6 from one end of the spring pin mounting groove 5 until the conical part 11 is in place and its large-diameter section forms an interference fit with the spring pin mounting groove 5.

[0030] In this design, the insertion portion 8, spring 9, cylindrical body of the isolation support portion 10, and conical portion 11 of the spring pin isolator 6 are coaxially arranged. The insertion portion 8, spring 9, and cylindrical body of the isolation support portion 10 are clearance-fitted with the spring pin mounting groove 5 to ensure free movement within the groove. This allows the entire spring pin isolator 6 to be inserted and installed from one end of the groove 5, enabling smooth movement of the insertion portion 8, spring 9, and cylindrical body of the isolation support portion 10 along the groove 5. Similarly, the small-diameter section of the conical portion 11 can move smoothly along the groove 5 until the large-diameter section of the conical portion 11 enters the groove 5 and forms an interference fit. If the large-diameter section of the conical portion 11 can no longer be pushed into the groove, it can be hammered until it is fully inserted into the groove 5. As mentioned above, when inserting the spring pin isolator 6, the eccentric body of the isolation support portion 10 should protrude from the opening of the spring pin mounting groove 5; otherwise, it cannot be inserted and installed.

[0031] It should be noted that since the isolation support part 10 of the spring pin isolation part 6 needs to bear the contact force transmission function, it needs to have a certain length. Compared with the conventional spring pin, the overall length will increase, and the length of the sleeve body 4, the spring pin mounting groove 5, etc. will also increase accordingly.

[0032] In this embodiment, the cone portion 11 can be made of hard plastic, and the isolation support portion 10 can be made of wear-resistant, high-strength, hard non-metallic material. The high-strength, hard non-metallic material of the isolation support portion 10 effectively solves the corrosion problem caused by the contact between steel and aluminum, and does not affect the ease of installation of the beam 1 and the column 2.

[0033] In a preferred embodiment, the spring pin mounting grooves 5 are located at the center of each surface of the sleeve body 4, so that after installation, the isolation support 10 can better maintain the isolation between each surface of the sleeve body 4 and the crossbeam 1, making it less likely to fail during long-term use. At the same time, the spring pin mounting grooves 5 are relatively evenly distributed relative to the sleeve body 4 and correspond to the mounting holes 7 on the side wall of the column 2, ensuring that the spring pin isolation member 6 transmits force evenly and avoids stress concentration.

[0034] 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 manufacturing, the spring pin isolator 6 is installed on the core body 4. After installation, the spring pin isolator 6 is located inside the core body 4, except that the insertion part 8 protrudes from one end face of the core body 4; the core body 4 is inserted from both ends of the beam 1, with the protruding end of the insertion part 8 of the spring pin isolator 6 on the core body 4 facing outwards. When the core body 4 is just fully inserted into the beam 1, the limiting screw is used. 12. Fix the positions of the two (the limit screw 12 passes through the crossbeam 1 and presses down on the corresponding cone part 11); make a mounting hole 7 on the side wall of the column 2 where the crossbeam 1 is connected, which is matched with the spring pin isolation part 6; transport the assembled crossbeam 1 and column 2 to the installation site, install the column 2 first, and when installing the crossbeam 1, just compress the plug part 8 so that it is pushed from front to back along the side wall of the column 2. After reaching the position of the mounting hole 7, the plug part 8 will automatically spring into the mounting hole 7 under the action of elastic force. The quick connection installation of the crossbeam 1 and the column 2 is completed.

[0035] 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.

[0036] 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.
