Description

A steel installation structure for seismic bracing Technical Field

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

[0002] In seismic design of buildings, seismic bracing plays a crucial role. Currently, seismic bracing is typically installed manually by attaching the connecting base to the top of a concrete wall, steel beam, or purlin, and then connecting the steel profile to the connecting base using bolt assemblies through mounting holes in both the connecting base and the steel profile.

[0003] However, in actual construction, due to various reasons such as incorrect installation position calculations and construction errors, it is often necessary to fine-tune the installation height of the steel profile. However, the existing connecting base corresponds to the mounting holes on the steel profile. When multiple mounting holes are made on the steel profile, a large interval between the holes needs to be designed to ensure its overall strength. This makes it impossible to fine-tune the installation position of the steel profile on the connecting base, making it difficult to effectively address errors during the installation process.

[0004] When such problems occur, additional drilling is often required to complete the connection, which not only increases construction costs and time but may also affect the structural strength of the steel section. Therefore, it is urgent to improve the existing installation structure of seismic bracing to enhance its flexibility and adaptability. Summary of the Invention

[0005] The purpose of this utility model is to provide a steel installation structure for seismic bracing. Through a special structural design, it solves the problems of the inability to fine-tune the installation position of the steel in seismic bracing and the inconvenience of installation in the prior art, improves the flexibility and adaptability of seismic bracing installation, reduces construction costs and time, and ensures the structural strength of the steel.

[0006] To achieve the above objectives, this utility model provides a steel profile installation structure for seismic bracing, comprising a steel profile body, a connecting base, and a bolt assembly, the specific structure of which is as follows:

[0007] Steel body: The steel body includes a first web and first flanges located on both sides of the first web. A plurality of first pentagonal star holes are formed on the first flanges along their length. The steel body is 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, ensuring the overall load-bearing capacity of the seismic bracing after connection, and meeting the strength and stability requirements of the seismic bracing in actual use.

[0008] Bolt assembly: The bolt assembly includes a bolt and a nut. The bolt includes a threaded portion and a pentagonal portion, with the threaded portion threadedly connected to the nut. The pentagonal portion has a pentagonal cross-section, the dimensions of which are adapted to a first pentagonal hole, allowing it to be inserted into the first pentagonal hole, which restricts the rotation of the pentagonal portion.

[0009] Connecting base: The connecting base includes a U-shaped connector with a U-shaped cross-section. The U-shaped connector has a pentagonal combination hole. The U-shaped connector is connected to the steel body via a bolt assembly. The pentagonal combination hole forms at least two locking structures that can slide and engage with the pentagonal part. The pentagonal part slides and engages with one of the locking structures of the first pentagonal hole and the pentagonal combination hole. The screw part passes through the pentagonal combination hole and the first pentagonal hole and is threadedly connected to a nut.

[0010] Furthermore, the pentagonal combination hole is composed of two upper and lower second pentagonal holes and a connecting hole in the middle. The upper and lower second pentagonal holes are symmetrical about the horizontal center line of the pentagonal combination hole; the connecting hole in the middle partially overlaps with the upper and lower second pentagonal holes.

[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 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 the second limiting surface and the first limiting surface adjacent to it is 252 degrees. The second limiting surface and the first limiting surface that are not adjacent to it are arranged parallel to each other. This precise setting of the limiting surface angle and position can accurately limit the pentagonal part, ensuring that the bolt can be stably fixed in different snap-fit ​​positions, and preventing the bolt from loosening or shifting due to external force during use.

[0012] The U-shaped connector includes a second web and second flanges located on both sides of the second web, with the two second flanges arranged in parallel. The pentagonal combination hole can be formed on the second web or on the second flange, or on both the second web and the second flange.

[0013] When the pentagonal combination hole is opened on the second web plate, the screw part passes through the pentagonal combination hole and the corresponding first pentagonal hole on the two first flanges, and is threadedly connected to the nut.

[0014] When the pentagonal combination hole is opened on the second flange, the screw part passes through the corresponding pentagonal combination hole on the two second flanges and the corresponding first pentagonal hole on the two first flanges, and is threadedly connected to the nut.

[0015] When the pentagonal combination hole is formed on the second web and the second flange, the lengths of the first web and the first flange in the cross-section need to be equal, and the two first flanges should be arranged in parallel. In this case, the screw part passes through the pentagonal combination hole on the second web and the corresponding first pentagonal hole on the two first flanges, and then is threadedly connected to the nut; or, the screw part passes through the corresponding pentagonal combination hole on the two second flanges and the corresponding first pentagonal hole on the two first flanges, and then is threadedly connected to the nut.

[0016] In addition, the connecting base also includes a base plate that is fixedly connected to the U-shaped connector. The base plate has mounting holes to facilitate the installation of the connecting base on the top of a concrete wall, under a steel beam, or under a purlin.

[0017] Beneficial effects: 1. This utility model sets a first pentagonal star hole on the first flange of the steel body and sets a pentagonal star combination hole with multiple snap-fit ​​structures on the U-shaped connector of the connecting base. During the installation process, according to the actual installation error, the pentagonal part of the bolt can be selected to slide and snap-fit ​​with the first pentagonal star hole at a suitable position in the pentagonal star combination hole, so as to realize the fine adjustment of the installation position of the steel body. This effectively solves the connection problem caused by installation error, eliminates the need for additional drilling, reduces construction costs and time, and ensures that the structural strength of the steel body is not affected.

[0018] 2. The five-pointed star part of the bolt assembly, together with the snap-fit ​​structure of the first five-pointed star hole and the five-pointed star combination hole, can restrict the rotation of the bolt. Combined with the threaded connection between the screw part and the nut, a connection method combining snap-fit ​​and threaded connection is formed between the steel body and the connecting base, ensuring the tightness and stability of the connection.

[0030] 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.

[0031] Please refer to Figures 1 to 10. This application provides a steel mounting structure for seismic bracing, including a steel body 1, a connecting base 2, and a bolt assembly, wherein:

[0032] The steel body 1 includes a first web 11 and first flanges 12 located on both sides of the first web 11. A plurality of first pentagonal holes 121 are provided on the first flanges 12 along their length direction.

[0033] In this embodiment, the steel body 1 is set as a C-shaped steel, but in other embodiments, the steel body 1 can also be set as a channel steel. C-shaped steel and channel steel are commonly used steel materials in seismic bracing, which have good mechanical properties and structural strength, and can ensure the overall load-bearing capacity of the seismic bracing after connection, meeting the strength and stability requirements of the seismic bracing in actual use.

[0034] The bolt assembly includes a bolt 3 and a nut 4. The bolt 3 includes a threaded portion 31, a pentagonal portion 32, and a threaded head 33. The pentagonal portion 32 is located between the threaded portion 31 and the threaded head 33. The cross-section of the pentagonal portion 32 is pentagonal, and its size is adapted to the first pentagonal hole 121, allowing it to be inserted into the first pentagonal hole 121. The first pentagonal hole 121 restricts the rotation of the pentagonal portion 32.

[0035] It should be noted that the screw section 31, screw head 33 and pentagon section 32 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.

[0036] The connecting base 2 includes a U-shaped connector 21 with a U-shaped cross-section. The U-shaped connector 21 has a five-pointed star combination hole 22. The U-shaped connector 21 is connected to the steel body 1 via a bolt assembly. If the premise of ensuring the five-pointed star portion 32 slides into the first five-pointed star hole 121 is removed, the five-pointed star combination hole 22 forms three locking structures 221 capable of slidingly engaging with the five-pointed star portion 32. Under the premise of ensuring the five-pointed star portion 32 slides into the first five-pointed star hole 121, only two of the three locking structures 221 formed by the five-pointed star combination hole 22 can slide into the five-pointed star portion 32 simultaneously inserted into the first five-pointed star hole 121 during installation.

[0037] The pentagonal part 32 is slidably engaged with one of the snap-fit ​​structures 221 of the first pentagonal hole 121 and the pentagonal combination hole 22; 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.

[0038] To further improve installation flexibility and adaptability, this embodiment features a special design for the pentagonal combination hole 22. The pentagonal combination hole 22 is composed of two upper and lower second pentagonal holes 222 and a central connecting hole 223. The upper and lower second pentagonal holes 222 are symmetrical about the horizontal center line 224 of the pentagonal combination hole 222. The central connecting hole 223 partially overlaps with the upper and lower second pentagonal holes 222, and the two upper and lower second pentagonal holes 222 also partially overlap. Both the second pentagonal holes 222 and the central connecting hole 223 form a snap-fit ​​structure 221 that allows the pentagonal part 32 to pass through while restricting its rotation.

[0039] 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 as needed to increase installation flexibility.

[0040] The second pentagonal 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 pentagonal holes 222 are symmetrical about the horizontal center line 224 of the pentagonal combination hole 222, and the two second limiting surfaces 2231 are symmetrical about the horizontal center line 224 of the pentagonal combination hole 222. The included angle of the two second limiting surfaces 2231 is 108 degrees, which matches the sharp corner of the pentagonal part 32. 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. This precise setting of the limiting surface angle and position can accurately limit the pentagonal part 32, ensuring that the bolt 3 can be stably fixed in different snap-fit ​​positions, and preventing the bolt 3 from loosening or shifting due to external force during use.

[0041] The U-shaped connector 21 includes a second web 211 and second flanges 212 located on both sides of the second web 211, with the two second flanges 212 arranged in parallel. The pentagonal combination hole 22 can be formed on the second web 211 or the second flange 212, or on both the second web 211 and the second flange 212.

[0042] In one embodiment, a five-pointed star combination hole 22 is provided on the second web plate 211. There are two five-pointed star combination holes 22 on the second web plate 211. The screw part 31 passes through the five-pointed star combination hole 22 and the corresponding first five-pointed star hole 121 on the two first flanges 12, and is threadedly connected to the nut 4.

[0043] During installation, place the steel body 1 in a suitable position, aligning the first pentagonal hole 121 on the first flange 12 with the pentagonal combination hole 22 on the second web 211 of the U-shaped connector 21. Insert the pentagonal part 32 of the bolt 3 into one of the snap-fit ​​structures 221 of the first pentagonal hole 121 and the pentagonal combination hole 22, allowing the bolt part 31 to pass through the pentagonal combination hole 22 and the first pentagonal holes 121 of the two first flanges 12. Screw on the end of the bolt part 31 that protrudes, and by tightening the nut 4, the steel body 1 is connected to the connecting base 2. During installation, as shown in Figures 6 and 7, different snap-fit ​​structures 221 for the pentagonal part 32 and the pentagonal combination hole 22 can be selected according to the actual installation error, thereby achieving fine-tuning of the installation position of the steel body 1.

[0044] In one embodiment, a pentagram combination hole 22 is provided on the second flange 212, and there are two pentagram combination holes 22 on the second flange 212. The screw part 31 passes through the corresponding pentagram combination holes 22 on the two second flanges 212 and the corresponding first pentagram holes 121 on the two first flanges 12, and is then threadedly connected to the nut 4.

[0045] During installation, place the steel body 1 in a suitable position, aligning the first pentagonal hole 121 on the first flange 12 with the pentagonal combination hole 22 on the second flange 212 of the U-shaped connector 21. Insert the pentagonal part 32 of the bolt 3 into one of the snap-fit ​​structures 221 of the first pentagonal hole 121 and the pentagonal combination hole 22, allowing the bolt part 31 to pass through the pentagonal combination holes 22 on the two second flanges 212 and the first pentagonal holes 121 on the two first flanges 12. Screw on the end of the bolt part 31 that protrudes, and tighten the nut 4 to connect the steel body 1 to the connecting base 2. During installation, as shown in Figures 6 and 7, different snap-fit ​​structures 221 for the pentagonal part 32 and the pentagonal combination hole 22 can be selected according to the actual installation error, thereby achieving fine-tuning of the installation position of the steel body 1.

[0046] In one embodiment, as shown in FIG4, a pentagram combination hole 22 is provided on the second web 211 and the second flange 212. The number of pentagram combination holes 22 on the second web 211 and the second flange 212 is two. This embodiment requires that the lengths of the first web 11 and the first flange 12 on the cross section be equal, and the two first flanges 12 are arranged in parallel.

[0047] During installation, either of the two embodiments described above can be referred to. Since the first web plate 11 and the first flange 12 are of equal length, the installation angle can be switched by rotating the steel body 1 by 90 degrees, as shown in Figures 3 and 8. The steel body 1 can be inserted into the U-shaped connector 21 and connected to the U-shaped connector 21 in both states before and after rotating 90 degrees, which facilitates construction and installation.

[0048] The design of multiple opening positions for the five-pointed star combination holes 22 on the U-shaped connector 21, and the option to use C-shaped steel or channel steel for the steel body 1, makes this installation structure suitable for different installation spaces and connection requirements, improving the versatility and adaptability of the connection structure.

[0049] In some embodiments, as shown in FIG1, the connecting base 2 further includes a base plate 23 fixedly connected to the U-shaped connector 21. The base plate 23 has mounting holes, which facilitates the installation of the connecting base 2 on the top of a concrete wall, steel beam, or purlin using anchor bolts or other fasteners passing through the mounting holes.

[0050] Furthermore, in some embodiments, as shown in FIG1, a plurality of waist-shaped holes 111 are provided on the web plate 11 along its length direction. The waist-shaped holes 111 facilitate the connection and installation of the steel body 1 with other components during the installation process, while reducing the weight of the steel body 1 to a certain extent, reducing material costs, and without affecting the overall strength and performance of the steel body 1.

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.

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.
