Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering technology, and in particular to a connection mechanism for steel structures in civil engineering. Background Technology
[0002] Civil engineering is a general term for the science and technology of constructing various engineering facilities. It covers many fields such as building construction, roads, bridges, and tunnels. In civil engineering construction, steel structures are widely used due to their advantages such as high strength, light weight, and fast construction speed. Steel structure connection mechanisms are devices used to firmly connect various steel structure components together. The reliability and stability of their connections directly affect the quality and safety of the entire steel structure project.
[0003] The existing steel structure connection mechanism for civil engineering has the following shortcomings:
[0004] Traditional steel structure connection methods, such as welding, can cause uneven heating of the steel due to the high temperatures generated during the welding process, leading to thermal deformation. This affects the dimensional accuracy and overall stability of the steel structure, resulting in problems such as deviations at the connection points and a decrease in the structural load-bearing capacity. At the same time, if existing devices use bolted connections, the bolts are prone to loosening under long-term dynamic loads or vibrations, causing gaps at the connection nodes, reducing the rigidity of the structure, and potentially leading to safety hazards in extreme cases. Utility Model Content
[0005] This utility model proposes a connection mechanism for steel structures in civil engineering. By rotating a hexagonal knob, a bidirectional screw is driven to slide the threaded sliding plate, which in turn drives the limiting sliding plate and the sliding clamping plate. The sliding clamping plate inserts into the fixed clamping groove to secure the I-shaped structural steel. Combined with the inclined sliding groove, sliding insert, and nut, this not only avoids thermal deformation and improves construction accuracy but also enhances connection stability and vibration resistance, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a civil engineering steel structure connection mechanism, comprising two I-shaped structural steels arranged on the left and right, with connecting components fixedly installed on the front and rear sides of the inner surfaces of the two I-shaped structural steels, and fixed slots extending through the upper and lower surfaces on the left and right sides of the I-shaped structural steels, and connecting through holes extending through the front and rear on the left and right sides of the interior of the I-shaped structural steels.
[0007] The connecting assembly includes connecting plates, two of which are respectively disposed on the front and rear sides of the inner surfaces of two I-shaped structural steels. Each connecting plate has a vertically penetrating connecting groove on its left and right sides. Hexagonal knobs are rotatably connected to the upper and lower sides of each connecting plate's left and right surfaces. A bidirectional screw is fixedly connected to the opposite faces of the two hexagonal knobs. The left and right ends of the bidirectional screw are slidably connected to the interiors of the two connecting grooves. Threaded sliding plates are threadedly connected to the left and right sides of the outer surface of the bidirectional screw. The outer surface of the threaded sliding plates is slidably connected to the inner surface of the connecting grooves. Vertically penetrating limiting grooves are provided on the front and rear sides of the threaded sliding plates. Limiting sliding plates are slidably connected to the inner surfaces of the limiting grooves. A sliding retaining plate is fixedly connected to the end of each limiting sliding plate closest to the I-shaped structural steel. The end of the sliding retaining plate away from the limiting sliding plate extends into the interior of the fixed retaining groove.
[0008] Preferably, the connecting plate has a sliding groove that runs through the center of both the left and right sides, and the inner surfaces of the two sliding grooves are slidably connected to a sliding post that runs through the center.
[0009] Preferably, the middle part of the outer surface of the sliding insert is slidably connected to the inner surface of the connecting through hole.
[0010] Preferably, both ends of the sliding insert are fixedly connected to threaded posts, and the outer surface of the threaded posts is threaded with nuts.
[0011] Preferably, a sliding baffle is fixedly connected to the end of each of the two limiting slide plates away from the sliding plate.
[0012] Preferably, the front and rear surfaces of the connecting slide are provided with inclined slides on both the upper and lower sides, and a sliding block is fixedly connected to the side of the limiting slide away from the threaded slide. The outer surface of the sliding block is slidably connected to the inner surface of the inclined slide.
[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0014] 1. In this utility model, rotating the hexagonal knob drives the bidirectional screw to rotate. The rotation of the bidirectional screw causes the threaded sliding plate to slide in opposite directions within the connecting groove. The threaded sliding plate drives the limiting sliding plate and the sliding clamping plate to move. The sliding clamping plate inserts into the fixed clamping groove to clamp the I-shaped structural steel. Through this structural design of the connection component and the fixed clamping groove of the I-shaped structural steel, high-temperature welding is not required, avoiding the impact of thermal deformation on the structural accuracy. The connection can be completed quickly and accurately, improving construction efficiency and the accuracy of the connection parts, and enhancing the reliability of the steel structure connection.
[0015] 2. In this utility model, when the threaded slide plate slides in the connecting groove, the sliding block on the limiting slide plate slides in the inclined groove. The inclined groove drives the sliding block to slide up and down, which can effectively control the sliding plate to insert into the fixed slot from the inside of the connecting groove, thereby achieving the clamping of the fixed slot. At the same time, the sliding pin passes through the sliding through groove and the connecting through hole and is fixed by the nut, which further enhances the stability of the connection. This structural design makes the connection part less prone to loosening when the connection mechanism is subjected to dynamic loads or vibrations, effectively improving the rigidity and stability of the structure and reducing safety risks.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: it includes two I-shaped structural steels 1 arranged left and right. Connecting components 2 are fixedly installed on the front and rear sides of the inner surface of the two I-shaped structural steels 1. Fixed slots 11 that pass through the upper and lower surfaces of the I-shaped structural steels 1 are opened on the left and right sides. Connecting through holes 12 that pass through the front and rear are opened on the left and right sides of the interior of the I-shaped structural steels 1. The connecting components 2 include connecting plates 21. The two connecting plates 21 are respectively arranged on the front and rear sides of the inner surface of the two I-shaped structural steels 1. Sliding slots 22 that pass through the front and rear are opened in the middle of the left and right sides of the connecting plates 21. A sliding insert 23 that passes through the front and rear is slidably connected to the inner surface of the two sliding slots 22. The middle of the outer surface of the sliding insert 23 is slidably connected to the inner surface of the connecting through hole 12. Threaded posts 24 are fixedly connected to the front and rear ends of the sliding insert 23. Nuts 25 are threadedly connected to the outer surface of the threaded posts 24.
[0025] The effect achieved by the entire embodiment 1 is as follows: by sliding the insert 23 through the sliding groove 22 of the front and rear connecting plates 21 and the connecting through hole 12 of the I-shaped structural steel 1, and then tightening the threaded post 24 with the nut 25, the two I-shaped structural steels 1 are initially positioned and connected in the front and rear direction, laying the foundation for a more stable connection operation in the future. This connection method can quickly align the relative positions of the two I-shaped structural steels 1 and improve the installation efficiency.
[0026] Example 2: As Figure 4 and Figure 5 As shown, this utility model provides a technical solution: Connecting plates 21 have vertically penetrating connecting grooves 26 on both their left and right sides. Hexagonal knobs 28 are rotatably connected to the upper and lower sides of the left and right surfaces of the connecting plate 21. A bidirectional screw 29 is fixedly connected to the opposite faces of the two hexagonal knobs 28. The left and right ends of the bidirectional screw 29 are slidably connected to the interiors of the two connecting grooves 26. Threaded sliding plates 210 are threadedly connected to the left and right sides of the outer surface of the bidirectional screw 29. The outer surface of the threaded sliding plates 210 is slidably connected to the inner surface of the connecting grooves 26. Vertically penetrating limiting grooves are provided on both the front and rear sides of the threaded sliding plates 210. 211, the inner surface of the limiting slide groove 211 is slidably connected to the limiting slide plate 212, and the end of the two limiting slide plates 212 near the I-shaped structural steel 1 is fixedly connected to a sliding plate 213. The end of the sliding plate 213 away from the limiting slide plate 212 extends into the interior of the fixed slot 11. The end of the two limiting slide plates 212 away from the sliding plate 213 is fixedly connected to a sliding baffle 214. The front and rear surfaces of the connecting slide groove 26 are provided with inclined slide grooves 27 on both the upper and lower sides. The side of the limiting slide plate 212 away from the threaded slide plate 210 is fixedly connected to a sliding block 215. The outer surface of the sliding block 215 is slidably connected to the inner surface of the inclined slide groove 27.
[0027] The effect achieved by the entire embodiment 2 is as follows: rotating the hexagonal knob 28 drives the bidirectional screw 29 to rotate. Since the threads at both ends of the bidirectional screw 29 are opposite, the threaded slide plate 210 slides in opposite directions within the connecting slide groove 26. When the threaded slide plate 210 slides, it drives the limiting slide plate 212 to move through the limiting slide groove 211. The sliding block 215 on the limiting slide plate 212 slides within the inclined slide groove 27. Due to the inclined design of the inclined slide groove 27, the sliding block 215 drives the limiting slide plate 212 and the sliding plate 213 to generate vertical force, thereby allowing the sliding plate 213 to be inserted into the fixed slot 11 at a suitable angle, achieving a stable clamping of the I-shaped structural steel 1 in the vertical direction, and enhancing the reliability and stability of the connection.
[0028] The working principle of the entire device is as follows: When installing two I-shaped structural steels 1, first place the two I-shaped structural steels 1 in the predetermined position so that the connecting components 2 correspond. Then, pass the sliding pins 23 through the sliding slots 22 of the front and rear connecting plates 21 and the connecting through holes 12 of the I-shaped structural steels 1 in sequence. Then, screw the nuts 25 onto the threaded pins 24 and tighten them to complete the initial front-to-back positioning connection. Next, rotate the hexagonal knob 28. The hexagonal knob 28 drives the bidirectional screw 29 fixedly connected to it to rotate. The rotation of the bidirectional screw 29 causes the threaded slide plate 210 to slide horizontally in the connecting groove 26. As the threaded slide plate 210 slides, the limiting slide plate 212 connects with the threaded slide plate 210 through the limiting groove 211. 10. During synchronous movement, the sliding block 215 on the limiting slide plate 212 slides within the inclined slide groove 27, causing the sliding plate 213 to move horizontally while simultaneously undergoing vertical displacement and angle adjustment. Ultimately, the sliding plate 213 is precisely inserted into the fixed slot 11, tightly clamping the two I-shaped structural steels 1 from the vertical direction. During equipment use, if subjected to dynamic loads or vibrations, the sliding insert 23 and the nut 25 work together to maintain a stable connection in the front-to-back direction. The tight engagement of the sliding plate 213 with the fixed slot 11 and the synergistic effect of the inclined slide groove 27 and the sliding block 215 prevent the connection from loosening, ensuring the rigidity and stability of the entire steel structure connection mechanism and reducing safety risks.
