Existing seismic bracing generally adopts a bolt connection method with fixed hole positions. The steel section and the connecting base, as well as the connector and the steel section, are fixedly connected through pre-set installation holes. When construction errors cause the holes to misalign, fine-tuning cannot be performed, and on-site drilling is required for adjustment. This not only increases construction costs but also weakens the structural strength of the steel section.

[0003] Therefore, there is an urgent need for a seismic support structure that can achieve rapid fine-tuning of the installation position, has high connection strength, and is adaptable to various scenarios. Utility Model Content

Detailed Implementation

[0042] 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.

[0043] Please see Figures 1 to 17 This application provides an adjustable seismic bracing system, including a base support and a connecting base 1.

[0044] The foundation support includes vertical steel sections 2, horizontal steel sections 3, connectors 4, and a first pentagonal bolt assembly. Two vertical steel sections 2 are arranged in parallel, and the horizontal steel sections 3 are arranged between the two vertical steel sections 2. At least one horizontal steel section 3 is provided. Connectors 4 are provided at both ends of the horizontal steel section 3. The connectors 4 include two connecting parts 41 for connecting the vertical steel section 2 and the horizontal steel section 3 respectively. Both connecting parts 41 are connected to the vertical steel section 2 and the horizontal steel section 3 through the first pentagonal bolt assembly.

[0045] Vertical steel section 2 and horizontal steel section 3 are both C-shaped steel, or both are channel steel, or part of them are C-shaped steel and the other part is channel steel; C-shaped steel and channel steel are commonly used steel materials in seismic bracing, with good mechanical properties and structural strength, which can ensure the overall load-bearing capacity of the seismic bracing after connection and meet the strength and stability requirements of the seismic bracing in actual use;

[0046] The connecting base 1 includes a base plate 11 and a U-shaped component 12 fixedly installed on the base plate 11. The U-shaped component 12 is connected to the vertical steel section 2 by a second pentagonal bolt assembly. The cross section of the U-shaped component 12 is U-shaped.

[0047] Both the vertical steel section 2 and the horizontal steel section 3 include a first web 21 and a first flange 22. The first flange 22 is located on both sides of the first web 21. Multiple first pentagonal holes 221 are provided on the first flange 22 along its length. The cross-section of the first pentagonal hole 221 is pentagonal.

[0048] Both the first and second pentagram bolt assemblies include a pentagram bolt 5 and a nut. The pentagram bolt 5 includes a threaded portion 51, a threaded head, and a pentagram portion 52. The pentagram portion 52 is located between the threaded portion 51 and the threaded head. The pentagram portion 52 can slide and engage with the first pentagram hole 221. The cross-section of the pentagram portion 52 is pentagram-shaped, and its size is adapted to the first pentagram hole 221, allowing it to be inserted into the first pentagram hole 221. The first pentagram hole 221 can restrict the rotation of the pentagram portion 52.

[0049] It should be noted that the screw section 51, the screw head and the pentagonal section 52 are an integral structure, which is made by casting or machine tool cutting. The material can be alloy steel to ensure that it has high strength.

[0050] Both connecting parts 41 and the U-shaped part 12 are provided with pentagram combination holes 13. The pentagram combination holes 13 form three snap-fit ​​structures 131 that can slide and snap into the pentagram part 52. The pentagram bolt 5 can choose any snap-fit ​​structure 131 to adapt to different installation position requirements. The snap-fit ​​structure 131 and the first pentagram hole 221 slide and snap into the pentagram part 52, which can provide circumferential restraint to the pentagram part 52, prevent the pentagram bolt 5 from rotating and loosening, and improve the connection reliability.

[0051] Under the premise of ensuring that the pentagonal part 52 is slidably engaged with the first pentagonal hole 221, only two of the three engagement structures 131 formed by the pentagonal combination holes 13 that can be slidably engaged with the pentagonal part 52 when it is installed can be slidably engaged with the pentagonal part 52 that is simultaneously inserted into the first pentagonal hole 221.

[0052] The screw portion 51 passes through the pentagonal combination hole 13 and the first pentagonal hole 221, and is threadedly connected to the nut.

[0053] In one implementation, please refer to Figures 1 to 17To further improve installation flexibility and adaptability, this embodiment features a special design for the pentagonal combination hole 13. The pentagonal combination hole 13 is composed of two upper and lower second pentagonal holes 132 and a central connecting hole 133. The upper and lower second pentagonal holes 132 are symmetrical about the horizontal center line 134 of the pentagonal combination hole 13. The central connecting hole 133 partially overlaps with the upper and lower second pentagonal holes 132, and the two upper and lower second pentagonal holes 132 also partially overlap. Both the second pentagonal holes 132 and the central connecting hole 133 form a snap-fit ​​structure 131 that allows the pentagonal part 52 to pass through while restricting its rotation.

[0054] The second pentagonal hole 132 includes a first limiting surface 1321, and the connecting hole 133 includes two second limiting surfaces 1331. The first limiting surfaces 1321 of the two second pentagonal holes 132 are symmetrical about the horizontal center line 134 of the pentagonal combination hole 13, and the two second limiting surfaces 1331 are also symmetrical about the horizontal center line 134 of the pentagonal combination hole 13. The included angle between the two second limiting surfaces 1331 is 108 degrees, and the included angle between the second limiting surface 1331 and the adjacent first limiting surface 1321 is 252 degrees. The second limiting surface 1331 and the non-adjacent first limiting surface 1321 are arranged parallel to each other. The included angle of 108° between the two second limiting surfaces 1331 matches the sharp corner of the pentagonal part 52. This specific angle design ensures the stability of the pentagonal bolt 5 in the snap-fit ​​position, prevents rotation, and achieves reliable positioning.

[0055] In one implementation, please refer to Figures 1 to 17 The U-shaped component 12 includes a second web 121 and second flanges 122 located on both sides of the second web 121, with the two second flanges 122 arranged in parallel. A five-pointed star combination hole 13 is provided on both the second web 121 and the second flange 122. The first web 21 and the first flange 22 are of equal length, and the two first flanges 22 are arranged in parallel. The screw portion 51 passes through the five-pointed star combination hole 13 on the second web 121 and the corresponding first five-pointed star hole 221 on the two first flanges 22, and is then threadedly connected to a nut. Alternatively, the screw portion 51 passes through the corresponding five-pointed star combination hole 13 on the two second flanges 122 and the corresponding first five-pointed star hole 221 on the two first flanges 22, and is then threadedly connected to a nut.

[0056] 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.

[0057] During installation, please refer to Figure 6 and Figure 7The first pentagonal hole 221 on the first flange 22 is aligned with the pentagonal combination hole 13 on the second web 121 of the U-shaped member 12. The pentagonal part 52 of the pentagonal bolt 5 is inserted into one of the snap-fit ​​structures 131 of the first pentagonal hole 221 and the pentagonal combination hole 13 on the second web 121, so that the screw part 51 passes through the pentagonal combination hole 13 and the first pentagonal hole 221 of the two first flanges 22. A nut is screwed onto the end of the screw part 51 that protrudes, and by tightening the nut, the vertical steel section 2 is connected to the connecting base 1. During the installation process, different snap-fit ​​structures 131 for the pentagonal part 52 and the pentagonal combination hole 13 can be selected for snap-fit ​​according to the actual installation error, thereby realizing the fine adjustment of the installation position of the vertical steel section 2.

[0058] Alternatively, during installation, please refer to [the relevant documentation]. Figure 8 The first pentagonal hole 221 on the first flange 22 is aligned with the pentagonal combination hole 13 on the second flange 122 of the U-shaped part 12. The pentagonal part 52 of the pentagonal bolt 5 is inserted into one of the snap-fit ​​structures 131 of the first pentagonal hole 221 and the pentagonal combination hole 13 on the second flange 122, so that the screw part 51 passes through the two pentagonal combination holes 13 on the two second flanges 122 and the two first pentagonal holes 221 on the two first flanges 22. A nut is screwed on the end of the screw part 51 that protrudes, and by tightening the nut, the vertical steel 2 is connected to the connecting base 1.

[0059] During installation, depending on the actual installation error, different snap-fit ​​structures 131 can be selected for snap-fit ​​between the pentagonal part 52 and the pentagonal combination hole 13, thereby achieving fine adjustment of the installation position of the vertical steel 2.

[0060] Since the first web 21 and the first flange 22 are of equal length, the installation angle can be switched by rotating the vertical steel section 2 by 90 degrees. The vertical steel section 2 can be inserted into the U-shaped piece 12 and connected to it in both the state before and after rotating 90 degrees, facilitating construction and installation.

[0061] In one embodiment, the connector 4 is provided as a T-shaped connector 4 and an L-shaped connector 4. One of the connecting parts 41 of the T-shaped connector 4 is provided with three pentagonal combination holes 13, and the spacing between the three pentagonal combination holes 13 is the same as the spacing between the first pentagonal hole 221. The other connecting part 41 of the T-shaped connector 4 is provided with one pentagonal combination hole 13. One of the connecting parts 41 of the L-shaped connector 4 is provided with two pentagonal combination holes 13, and the spacing between the two pentagonal combination holes 13 is the same as the spacing between the first pentagonal hole 221. The other connecting part 41 of the L-shaped connector 4 is provided with one pentagonal combination hole 13.

[0062] It is understandable that the designs of both the T-shaped and L-shaped connectors 4 facilitate the connection of two vertical steel sections 2 and horizontal steel sections 3. Furthermore, the reasonable arrangement of the number and position of the five-pointed star combination holes 13 ensures the strength and stability of the connection. Different types of connector plates can be applied to different installation spaces and connection requirements, improving the versatility of the connection structure.

[0063] When installing the seismic bracing, the approximate installation position of the connector 4 is determined by selecting a suitable first pentagonal hole 221 on the vertical steel section 2, and then the installation height is finely adjusted by selecting the snap-fit ​​structure 131 of the pentagonal combination hole 13 corresponding to the first pentagonal hole 221. When installing the horizontal steel section 3, the installation position in the horizontal direction is finely adjusted by selecting the snap-fit ​​structure 131 of the pentagonal combination hole 22 corresponding to the first pentagonal hole 221.

[0064] In one implementation, please refer to Figure 1 and Figure 2 Between two vertical steel sections 2, three horizontal steel sections 3 are arranged parallel to each other from top to bottom. The connectors 4 at both ends of the bottom horizontal steel section 3 are L-shaped, so that the lower end of the connector 4 does not extend beyond the bottom horizontal steel section 3. The connectors 4 at both ends of the top horizontal steel section 3 are L-shaped, or T-shaped connecting plates. The connectors 4 at both ends of the middle horizontal steel section 3 are T-shaped, or L-shaped connecting plates. Ventilation ducts 101, electrical conduits 102, and water pipes 103 are respectively installed on the three horizontal steel sections 3.

[0065] Compared to the above embodiment, in other embodiments, two horizontal steel sections 3 arranged parallel to each other from top to bottom can also be provided between the two vertical steel sections 2. The connectors 4 at both ends of the bottom horizontal steel section 3 are L-shaped connectors 4, and the connectors 4 at both ends of the top horizontal steel section 3 are also L-shaped connectors 4, or T-shaped connecting plates. Any two of the following can be installed on the two horizontal steel sections 3: ventilation duct 101, wiring duct 102, and water duct 103.

[0066] For other implementation methods compared to the two methods described above, please refer to [link / reference]. Figure 3 and Figure 4 Alternatively, a horizontal steel section 3 can be provided between two vertical steel sections 2. Any one of ventilation ducts 101, wiring ducts 102, and water pipes 103 can be installed on the horizontal steel section 3. In this embodiment, wiring ducts 102 are installed on the horizontal steel section 3.

[0067] In one embodiment, the horizontal steel section 3 is provided with two connectors 4 at both ends, the vertical steel section 2 is located between the two connectors 4, and the screw part 51 passes through the five-pointed star combination hole 13 on one of the connectors 4, the corresponding first five-pointed star hole 221 on the two first flanges 22 of the vertical steel section 2, and the five-pointed star combination hole 13 on the other connector 4 in sequence, and then is threadedly connected to the nut.

[0068] It is understandable that this double-sided connection method can provide greater connection force and stability compared to a single-sided connection. The double-sided clamping forms a stable mechanical system, which improves the pull-out resistance and lateral displacement resistance, and effectively resists seismic loads.

[0069] In some embodiments, a plurality of waist-shaped holes 211 are provided on the first web 21 along its length. The waist-shaped holes 211 facilitate the connection and installation of the transverse steel 3 and the longitudinal steel 2 with other components during installation, while reducing the weight of the transverse steel 3 and the longitudinal steel 2 to a certain extent, reducing material costs, and without affecting the overall strength and performance of the transverse steel 3 and the longitudinal steel 2.

[0070] To improve the overall strength of the seismic bracing, a longitudinal diagonal brace 6 is also provided, with one end of the longitudinal diagonal brace 6 connected to the transverse steel section 3 via a first adjustable hinge 7.

[0071] The first adjustable hinge 7 is connected to the transverse steel 3 by a fastening bolt passing through the waist-shaped hole 211. The waist-shaped hole 211 facilitates the installation of the first adjustable hinge 7.

[0072] Based on the actual site conditions, the angle of the longitudinal diagonal support 6 is adjusted by the first adjustable hinge 7 to ensure that it forms an effective support system with the main structure.

[0073] The first adjustable hinge 7 enables the longitudinal diagonal support 6 to not only be detachable but also rotatable. The posture of the longitudinal diagonal support 6 can be adjusted in a timely manner according to the actual situation to meet the installation requirements under different construction conditions.

[0074] The other end of the longitudinal diagonal support 6 is equipped with a second adjustable hinge. When installed under a concrete substrate, the second adjustable hinge is fixedly connected to the substrate, such as concrete, by expansion bolts 104.

[0075] When installed under the purlin 105, the second adjustable hinge is fixedly connected to the crossbeam 106 by fastening bolts, and the crossbeam 106 is connected to the purlin 105 by fastening bolts through an L-shaped limiting fastener.

[0076] To further improve the overall strength of the seismic bracing, a lateral inclined support 8 is also provided, which is connected to the vertical steel section 2 via a third adjustable hinge 9.

[0077] The third adjustable hinge 9 is connected to the vertical steel section 2 by a fastening bolt passing through the waist-shaped hole 211. The waist-shaped hole 211 facilitates the installation of the third adjustable hinge 9.

[0078] Based on the actual site conditions, the angle of the lateral oblique support 8 is adjusted by the third adjustable hinge 9 to ensure that it forms an effective support system with the main structure.

[0079] The third adjustable hinge 9 enables the lateral bracing 8 to not only be detachable but also rotatable. The posture of the lateral bracing 8 can be adjusted in a timely manner according to the actual situation to meet the installation requirements under different construction conditions.

[0080] The other end of the lateral diagonal support 8 is equipped with a fourth adjustable hinge. When installed under a concrete substrate, the fourth adjustable hinge is fixedly connected to the substrate in the concrete via expansion bolts 104. When installed under the purlin 105, the fourth adjustable hinge is fixedly connected to the crossbeam 106 via fasteners, and the crossbeam 106 is connected to the purlin 105 via L-shaped limiting fasteners and fastening bolts.
