Description

Technical Field

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

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of components such as beams, columns, and trusses made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets.

[0003] Existing steel structure connectors have the following shortcomings in use:

[0004] Traditional steel structure connection methods involve assembling two steel structural components using angle steel, bolts, and nuts. If the bolts are not tightened to the specified preload during installation, or if the steel structural components are subjected to vibration or impact loads, the bolts may loosen, causing the bolts and nuts to detach and potentially leading to hidden dangers. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology, which is that traditional steel structure connection methods typically involve assembling two steel structures using angle steel, bolts, and nuts. If the bolts do not reach the specified preload during installation, or if the steel structure is subjected to vibration or impact loads, the bolts are prone to loosening, causing the bolts and nuts to detach and potentially leading to hidden dangers. Therefore, this utility model proposes a steel structure connector for road and bridge construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel structure connector for road and bridge construction includes a first steel member and a second steel member. Angle steel is provided on both sides of the first steel member for connecting the first steel member and the second steel member. Through holes are provided on the angle steel, the first steel member and the second steel member. A first bolt is inserted between the through holes of the angle steel and the through holes of the first steel member and the second steel member. One end of the first bolt is threaded to a first nut for fastening the angle steel, the first steel member and the second steel member. Two slots are provided on the other two sides of the first steel member.

[0008] A reinforcing mechanism is provided between the first steel component and the second steel component. After the first steel component and the second steel component are fixed together by angle steel, the reinforcing mechanism can reinforce the relationship between the first steel component and the second steel component.

[0009] To prevent the first bolt and the first nut from coming off each other, the first bolt also includes an anti-loosening mechanism, which prevents the first nut from coming off the first bolt when the first nut and the first bolt are tightened into place.

[0010] In one possible design, the anti-detachment mechanism includes a wire for preventing the first nut and the first bolt from detaching from each other, with a plurality of insertion holes at one end of the first bolt, and the wire passing through the insertion holes.

[0011] In one possible design, the reinforcement mechanism includes a fixed plate, a short plate, a movable plate, two insert plates, and a second bolt. One side of the short plate is welded to one side of the fixed plate, one side of the movable plate is slidably connected to one side of the fixed plate, one side of each insert plate is welded to one side of the fixed plate, a second nut is embedded in one side of the short plate, and the second bolt is threadedly connected to the second nut. A bearing is fixedly installed at the bottom of the movable plate, and the top of the second bolt is fixedly connected to the inner wall of the inner ring of the bearing. The insert plates are inserted into slots, and a plug is fixedly installed at the top of the movable plate. An insertion groove is formed on the top inner wall of the second steel component, and the plug is inserted into the insertion groove.

[0012] In one possible design, a moving groove is provided on one side of the fixed plate to limit the moving plate and prevent it from rotating, and a moving block is fixedly provided on one side of the moving plate, with one side of the moving block slidably connected to the inner wall of the moving groove.

[0013] In one possible design, the reinforcement mechanism consists of two sets, located on either side of the first steel member.

[0014] In one possible design, the first steel component, the second steel component, the angle steel, the fixing plate, the short plate, the moving plate, the two insert plates, and the insert block are all made of weathering steel.

[0015] In this application, during installation, two angle steels are attached to both sides of the first steel member and positioned above the second steel member, aligning the through holes of the angle steels, the first steel member, and the second steel member. The first bolt is then inserted, and the first nut is tightened to initially fix the angle steels to the second and first steel members. Next, a wire is inserted into the insertion hole, and both ends of the wire are bent and wrapped around the first bolt to form an anti-loosening ring, preventing the first bolt and the first nut from detaching. Then, the fixing plate is moved to one side of the first and second steel members, aligned with the slot, and inserted. During insertion, the moving plate moves to the inside of the second steel member, aligning the fixing plate with the first and second steel members. Finally, the second bolt is rotated... The two bolts rotate within the second nut, pushing the moving plate and insert block upwards, causing the insert block to insert into the insertion slot of the second steel component. Simultaneously, the moving plate is pressed tightly against the inner top wall of the second steel component. The above operation is then repeated to install another set of reinforcement mechanisms, thereby reinforcing the first and second steel components. The first steel component, second steel component, angle steel, fixed plate, short plate, moving plate, two insert plates, and insert block are all made of weathering steel. Weathering steel can resist atmospheric corrosion without painting and has a long service life. Through the triple protection of mechanical reinforcement, anti-loosening design, and weathering materials, the reliability and durability of road and bridge steel structures can be significantly improved, making it suitable for key engineering scenarios such as long-span bridges and heavy-load roads.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this utility model, a steel structure connector for road and bridge construction uses an anti-detachment mechanism to insert a wire into the insertion hole, bend both ends of the wire and wrap it around the first bolt to form an anti-detachment ring, thereby preventing the first bolt and the first nut from detaching from each other.

[0018] In this utility model, a steel structure connector for road and bridge construction is described. Through a reinforcement mechanism, a fixing plate is moved to one side of the first and second steel components. An insert plate is aligned with the slot and inserted. During insertion, a moving plate moves to the inside of the second steel component, causing the fixing plate to adhere to both the first and second steel components. Then, the second bolt is rotated, causing it to rotate within the second nut, pushing the moving plate and insert block upwards. This allows the insert block to be inserted into the insertion slot of the second steel component, while simultaneously ensuring the moving plate is flush against the inner top wall of the second steel component. This process is repeated for the installation of another set of reinforcement mechanisms, thereby reinforcing the connection between the first and second steel components.

[0019] In this utility model, the anti-loosening mechanism can prevent the first bolt and the first nut from separating from each other, and the reinforcement mechanism can reinforce the first steel part and the second steel part. With the triple protection of mechanical reinforcement, anti-loosening design and weather-resistant materials, the reliability and durability of road and bridge steel structures can be significantly improved, and it is suitable for key engineering scenarios such as long-span bridges and heavy-load roads.
