Description

A steel connection structure for seismic bracing Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and in particular to a steel connection structure for seismic bracing. Background Technology

[0002] Seismic bracing is usually assembled manually from steel components and installed on top of concrete walls, under steel beams, or purlins.

[0003] In actual assembly, due to various reasons such as incorrect calculation of the installation position of the fixing point and construction errors, it often happens that the mounting holes of two steel sections that need to be connected together cannot be aligned with those of the connector.

[0004] Existing seismic bracing systems generally lack fine-tuning capabilities in their connection structures, making it difficult to effectively address errors during installation. When such errors occur, additional drilling is often required to complete the connection, increasing construction costs and time, and potentially impacting the structural strength of the steel sections. Therefore, improvements to the existing seismic bracing connection structures are urgently needed. Summary of the Invention

[0005] The purpose of this utility model is to provide a steel connection structure for seismic bracing, so as to solve the problem in the prior art that the mounting holes cannot be aligned due to installation errors during the connection of seismic bracing, which makes installation inconvenient.

[0006] To achieve the above objectives, this utility model provides a steel section connection structure for seismic bracing, including a steel section body and a connection assembly for connecting the steel section body. The connection assembly includes connectors and bolt assemblies. The steel section body includes a web and flanges located on both sides of the web, and a plurality of first pentagonal star holes are formed on the flanges along their length.

[0007] The bolt assembly includes a bolt and a nut. The bolt includes a shank, a head, and a pentagonal portion, with the pentagonal portion located between the shank and the head.

[0008] The connector includes two connecting parts, each connected to two vertically arranged steel profiles via bolt assemblies. Both connecting parts have pentagonal combination holes, forming multiple locking structures that can slide and engage with the pentagonal parts. These multiple locking structures further increase the adjustability of the bolt installation position. Depending on the actual installation situation, the pentagonal parts can be matched with different locking structures, effectively solving connection problems caused by installation errors and enhancing the stability of the connection structure.

[0009] The pentagonal part is slidably engaged with the first pentagonal hole and one of the snap-fit ​​structures; the screw part passes through the pentagonal combination hole and the first pentagonal hole and is threadedly connected to the nut. This ensures the stability of the connection.

[0010] Furthermore, the pentagonal combination hole consists of two upper and lower second pentagonal holes and a central connecting hole. The upper and lower second pentagonal holes are symmetrical about the horizontal center line of the pentagonal combination hole; the central connecting hole partially overlaps with the upper and lower second pentagonal holes. This special structural design allows the pentagonal part to have more snap-fit ​​options within the pentagonal combination hole, adapting to more complex installation error situations, improving the adaptability of the connection structure to different installation scenarios, and the symmetrical structure helps to evenly distribute the force on the connection parts, improving the stability of the connection.

[0011] Furthermore, the second pentagonal hole includes a first limiting surface, and the connecting hole includes two second limiting surfaces. The first limiting surfaces of the two second pentagonal holes are symmetrical about the horizontal center line of the pentagonal combination hole, and the two second limiting surfaces are also symmetrical about the horizontal center line of the pentagonal combination hole. The included angle between the two second limiting surfaces is 108 degrees, and the included angle between a second limiting surface and its adjacent first limiting surface is 252 degrees. The second limiting surface and its non-adjacent first limiting surface are arranged parallel to each other. The precise setting of the limiting surface angles and positions accurately limits the pentagonal portion, ensuring that the bolts are stably fixed in different snap-fit ​​positions, preventing loosening or displacement of the bolts due to external forces during use, and improving the reliability and safety of the connection structure.

[0012] The steel body is either C-shaped steel or channel steel. C-shaped steel and channel steel are commonly used steel materials in seismic bracing, possessing good mechanical properties and structural strength. Using these two types of steel as the body ensures the overall load-bearing capacity of the seismic bracing after connection, meeting the strength and stability requirements of the seismic bracing in actual use.

[0013] The two connecting parts are perpendicular to each other in length, and the connector is used to connect two vertically arranged steel profiles. As a preferred embodiment, the connector is a T-shaped connecting plate, with one connecting part having three pentagonal combination holes and the other connecting part having one pentagonal combination hole; or, the connector is an L-shaped connecting plate, with one connecting part having two pentagonal combination holes and the other connecting part having one pentagonal combination hole. The design of the T-shaped and L-shaped connecting plates facilitates the connection of two vertical steel profiles, and the reasonable setting of the number and position of the pentagonal combination holes ensures the strength and stability of the connection. At the same time, different types of connecting plates can be applied to different installation spaces and connection requirements, improving the versatility of the connection structure.

[0014] One or two connecting parts have bends on both sides in the width direction. The bends increase the stability of the connecting steel sections.

[0015] Both sides of the steel profile are equipped with connectors. The threaded part passes sequentially through the pentagonal combination hole on one connector, the corresponding first pentagonal hole on the two flanges, and the pentagonal combination hole on the other connector before being threaded into the nut. This double-sided connection method, compared with the single-sided connection, can provide greater connection force and stability, making the connection between the two steel profiles more secure. Under the action of external forces such as earthquakes, it reduces the risk of loosening of the connection and improves the overall performance of the seismic support.

[0016] In addition, multiple oblong holes are provided on the web plate along its length. The oblong holes facilitate the connection and installation of the steel profile with other components during installation, while also reducing the weight of the steel profile to a certain extent, lowering material costs, and without affecting the overall strength and performance of the steel profile.

[0017] The beneficial effects of this technical solution are: it effectively solves the problem in the existing technology that the steel connection structure of the seismic bracing cannot be finely adjusted, resulting in misalignment of the mounting holes due to installation errors and inconvenience in installation. It not only reduces construction costs and improves construction efficiency, but also enhances the stability and reliability of the connection structure, thereby improving the installation quality and performance of the seismic bracing.

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] Please refer to Figures 1 to 10. This application provides a steel connection structure for seismic bracing, including a steel body 1 and a connection assembly for connecting the steel body 1. The connection assembly includes a connector 2 and a bolt assembly.

[0031] Specifically, in this embodiment, please refer to Figure 1. The steel body 1 includes a web 11 and flanges 12 located on both sides of the web 11. A plurality of first pentagonal holes 121 are formed on the flanges 12 along their length. By forming the first pentagonal holes 121, the positions of two steel bodies 1 that need to be connected to each other can be determined according to the installation requirements. The connector 2 is connected to the two steel bodies 1 by passing bolt assemblies through the first pentagonal holes 121.

[0032] More specifically, in this embodiment, the steel body 1 is a C-shaped steel. C-shaped steel is a commonly used steel material in seismic bracing, possessing good mechanical properties and structural strength. Using C-shaped steel ensures the overall load-bearing capacity of the seismic bracing after connection, meeting the strength and stability requirements of the seismic bracing in actual use. In other embodiments, the steel body 1 may also be a channel steel.

[0033] In this embodiment, referring to Figures 2, 5, and 6, the bolt assembly includes a bolt 3 and a nut 4. The bolt 3 includes a threaded portion 31, a threaded head 32, and a pentagonal portion 33, with the pentagonal portion 33 located between the threaded portion 31 and the threaded head 32. The cross-section of the pentagonal portion 33 is pentagonal, and its dimensions are adapted to the first pentagonal hole 121, allowing it to be inserted into the first pentagonal hole 121, which restricts its rotation. The threaded portion 31, the threaded head 32, and the pentagonal portion 33 are an integral structure, manufactured by casting or machine tool cutting.

[0034] In this embodiment, referring to Figure 1, the connector 2 includes two connecting parts 21, which are respectively connected to two vertically arranged steel bodies 1 via bolt assemblies; each connecting part 21 has a pentagonal combination hole 22. If the premise of ensuring the pentagonal part 33 slides into the first pentagonal hole 121 is removed, the pentagonal combination hole 22 forms three locking structures 221 capable of slidingly engaging with the pentagonal part 33. Under the premise of ensuring the pentagonal part 33 slides into the first pentagonal hole 121, only two of the three locking structures 221 formed by the pentagonal combination hole 22 can slide into the pentagonal part 33 simultaneously inserted into the first pentagonal hole 121 during installation.

[0035] Understandably, the two snap-fit ​​structures 221 of the pentagonal combination hole 22 further increase the adjustability of the bolt 3 installation position. Depending on the actual installation situation, the pentagonal part 33 can be matched with different snap-fit ​​structures 221 to effectively solve the connection problem caused by installation error, while enhancing the stability of the connection structure.

[0036] In this embodiment, referring to Figure 1, the length directions of the two connecting parts 21 are perpendicular to each other, and the connector 2 is used to connect two vertically arranged steel bodies 1. Referring to Figures 1 to 4, the connector 2 is a T-shaped connecting plate, one of the connecting parts 21 has three pentagonal combination holes 22, and the spacing between the three pentagonal combination holes 22 is the same as the spacing between the first pentagonal hole 121. The other connecting part 21 has one pentagonal combination hole 22.

[0037] When installing the seismic bracing, the approximate installation position of the connector 2 is determined by selecting a suitable first pentagonal hole 121 on the longitudinally arranged steel body 1, and then the installation height is finely adjusted by selecting the snap-fit ​​structure 221 of the pentagonal combination hole 22 corresponding to the first pentagonal hole 121. When installing the transversely arranged steel body 1, the installation position in the horizontal direction is finely adjusted by selecting the snap-fit ​​structure 221 of the pentagonal combination hole 22 corresponding to the first pentagonal hole 121.

[0038] In other embodiments, please refer to Figures 7 to 10. The connector 2 may also be an L-shaped connector plate, with two pentagonal combination holes 22 on one of the connector parts 21. The spacing between the two pentagonal combination holes 22 is the same as the spacing between the first pentagonal hole 121. The other connector part 21 has one pentagonal combination hole 22.

[0039] It is understandable that the design of both T-shaped and L-shaped connecting plates facilitates the connection of two vertical steel bodies 1, and the reasonable arrangement of the number and position of the pentagonal combination holes 22 ensures the strength and stability of the connection. Different types of connecting plates can be applied to different installation spaces and connection requirements, improving the versatility of the connection structure.

[0040] In this embodiment, the pentagonal part 33 is slidably engaged with the first pentagonal hole 121 and one of the snap-fit ​​structures 221; the screw part 31 passes through the pentagonal combination hole 22 and the first pentagonal hole 121 and is threadedly connected to the nut 4.

[0041] Understandably, this connection method, which combines snap-fit ​​and threaded connection, not only ensures the tightness of the connection, but also uses the adjustability of the snap-fit ​​to compensate for installation errors, ensuring that the seismic bracing can be connected stably and reliably under various installation conditions.

[0042] In this embodiment, referring to Figures 4 and 10, the pentagram combination hole 22 is composed of two upper and lower second pentagram holes 222 and a middle connecting hole 223. The middle connecting hole 223 is set to one. The upper and lower second pentagram holes 222 are symmetrical about the horizontal center line 224 of the pentagram combination hole 222. The middle connecting hole 223 partially overlaps with the upper and lower second pentagram holes 222, and the two upper and lower second pentagram holes 22 also partially overlap. One of the second pentagram holes 222 and the middle connecting hole 223 both form a snap-fit ​​structure 221 that allows the pentagram part 33 to pass through and restricts the rotation of the pentagram part 33.

[0043] It is understandable that the number of snap-fit ​​structures 221 is related to the number of connecting holes 223 in the middle. Increasing the number of connecting holes 223 in the middle can increase the number of snap-fit ​​structures 221. If multiple connecting holes 223 in the middle are provided, one more snap-fit ​​structure 221 is added. In some embodiments, a corresponding number of connecting holes 223 in the middle can be added according to actual needs to increase installation flexibility.

[0044] In this embodiment, this special structural design allows the pentagonal combination hole 22 to form two snap-fit ​​structures 221 that can slide and snap-fit ​​with the pentagonal part 33. This gives the pentagonal part 33 the opportunity to select the snap-fit ​​position in the pentagonal combination hole 22, which can adapt to more complex installation error situations and improve the adaptability of the connection structure to different installation scenarios. Furthermore, the symmetrical structure helps to evenly distribute the force on the connection part 21 and improve the stability of the connection.

[0045] Furthermore, the second pentagram hole 222 includes a first limiting surface 2221, and the connecting hole 223 includes two second limiting surfaces 2231. The first limiting surfaces 2221 of the two second pentagram holes 222 are symmetrical about the horizontal center line 224 of the pentagram combination hole 22, and the two second limiting surfaces 2231 are symmetrical about the horizontal center line 224 of the pentagram combination hole 22. The included angle between the two second limiting surfaces 2231 is 108 degrees, which matches the sharp corner of the pentagram part 33. The included angle between the second limiting surface 2231 and the first limiting surface 2221 adjacent to it is 252 degrees. The second limiting surface 2231 and the first limiting surface 2221 that are not adjacent to it are arranged in parallel, which can facilitate engagement with the pentagram part 33.

[0046] It is understandable that precise setting of the limiting surface angle and position can accurately limit the pentagon part 33, ensuring that the bolt 3 can be stably fixed in different snap-fit ​​positions, preventing the bolt 3 from loosening or shifting due to external force during use, and improving the reliability and safety of the connection structure.

[0047] In this embodiment, referring to Figure 1, one of the connecting parts 21 has bends 211 on both sides in its width direction. The bending angle is 90 degrees. The steel section is located between the two bends 211, which can increase the stability of the connecting part 2 connecting the steel section. Even if the bolt 3 comes loose, the bends 211 still support the transverse steel section, and the bends 211 can play a safety role, ensuring the stability and reliability of the entire connection structure.

[0048] In some other embodiments, the two connecting portions 21 may be provided with bends 211 on both sides in the width direction, which further increases the structural strength and rigidity of the connecting portions 21.

[0049] In this embodiment, please refer to Figures 1 and 2. Both sides of the steel body 1 are provided with connectors 2. The screw part 31 passes through the five-pointed star combination hole 22 on one of the connectors 2, the corresponding first five-pointed star hole 121 on the two flanges 12 and the five-pointed star combination hole 22 on the other connector 2 in sequence, and is then threadedly connected to the nut 4.

[0050] Understandably, this double-sided connection method provides greater connection force and stability compared to a single-sided connection, making the connection between the two steel bodies 1 more robust. Under the action of external forces such as earthquakes, it reduces the risk of loosening of the connection part 21 and improves the overall performance of the seismic bracing.

[0051] Furthermore, in some embodiments, as shown in Figure 2, the web 11 has multiple oblong holes 111 along its length. The oblong holes 111 facilitate the connection and installation of the steel body 1 with other components during installation, while also reducing the weight of the steel body 1 to a certain extent, lowering material costs, and without affecting the overall strength and performance of the steel body 1.

[0052] 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.

[0053] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
