Description

Technical Field

[0001] This utility model relates to the field of steel structure bridge technology, specifically to an assembled steel structure bridge connection device. Background Technology

[0002] During bridge construction, the bridge needs to withstand heavy pressure, and when connecting the connecting devices, fixing devices are needed to connect and secure them.

[0003] As disclosed in the authorized publication number CN116254756B, the assembled steel structure bridge connection device includes a first steel structure and a second steel structure, which are interlocked and locked together by a locking structure. The locking structure includes an extension member installed within the interlocking position of the second steel structure and a limiting groove formed within the second steel structure. The extension member extends towards the limiting groove under external force and inserts into the limiting groove, thus fixing the first and second steel structures relatively. The beneficial effects of this invention using the above technical solution are: it facilitates adjusting the installation angle; once the installation angle is determined, the extension member extends downwards, engaging with the limiting groove, thereby achieving complete installation.

[0004] While the aforementioned patent facilitates installation, the fixing structure is located inside the steel structure. Due to the difficulty in processing and assembling the internal connecting structure, the time required for each process will increase accordingly. For example, when performing internal welding, welders need to spend more time adjusting the welding position and angle, and multiple welding operations are required to complete a complete weld, which significantly extends the welding process time. Utility Model Content

[0005] The purpose of this utility model is to provide an assembled steel structure bridge connection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An assembled steel structure bridge connection device, comprising

[0008] A connecting structure, wherein steel structure bodies are symmetrically arranged at both ends of the connecting structure, and a connecting mechanism is provided between the connecting structure and the steel structure bodies;

[0009] An I-shaped groove is provided in the middle of the connecting structure, and a fixing mechanism is provided between the connecting mechanism and the I-shaped groove.

[0010] Preferably, the connecting mechanism includes slots, with slots penetrating at both ends of the connecting structure, and inserts matching the slots provided at both ends of the steel structure body;

[0011] Preferably, a T-shaped groove is formed in the middle of the insert block;

[0012] Preferably, the fixing mechanism includes an I-beam plate, which is snapped between the T-slot and the I-beam slot;

[0013] Preferably, a fastener is provided on one side of the front of the I-beam plate, and a rectangular groove communicating with the slot on the left side is provided on the front of the connecting structure. The rectangular groove matches the fastener, and the fastener, the I-beam plate and the slot on the right side are fixedly connected by hexagonal bolts.

[0014] Preferably, positioning rods are provided at each of the four corners of both ends of the connecting structure, and positioning grooves matching the positioning rods are provided at each of the four corners of both ends of the steel structure body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The present invention relates to an assembled steel structure bridge connection device. In the prior art, the fixing structure is set inside the steel structure, which makes the processing and assembly of the internal connection structure difficult and increases the time required for each process. For example, in the welding process, the welder needs to spend more time adjusting the position and angle and needs to perform multiple welding operations. The present invention effectively solves this problem by setting the fixing mechanism in a relatively external position.

[0017] 2. The assembled steel structure bridge connection device further enhances the connection's firmness through a fixing mechanism. The I-beam steel plate is snapped between the T-slot of the insert block and the I-beam slot of the connection structure, allowing the I-beam steel plate to fit tightly against both, providing a larger contact area and stronger friction, effectively dispersing the stress.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution:

[0026] An assembled steel structure bridge connection device includes a connection structure 1, with steel structure bodies 2 symmetrically arranged at both ends of the connection structure 1. A connection mechanism is provided between the connection structure 1 and the steel structure bodies 2. The connection mechanism includes slots 4. Slots 4 are opened through both ends of the connection structure 1. Inserts 5 that match the slots 4 are provided at both ends of the steel structure bodies 2. A T-shaped groove 6 is opened in the middle of the inserts 5. Positioning rods 11 are provided at the four corners of both ends of the connection structure 1. Positioning grooves 12 that match the positioning rods 11 are provided at the four corners of both ends of the steel structure bodies 2.

[0027] In this embodiment, the existing fixing structure is set inside the steel structure, which makes the processing and assembly of the internal connection structure 1 difficult and increases the time required for each process. For example, in the welding process, the welder needs to spend more time adjusting the position and angle and perform multiple welding operations. This technical solution effectively solves this problem by setting the fixing mechanism in a relatively external position.

[0028] like Figure 2 and Figure 5 As shown, an I-shaped groove 3 is provided in the middle of the connecting structure 1. A fixing mechanism is provided between the connecting mechanism and the I-shaped groove 3. The fixing mechanism includes an I-beam steel plate 7. The I-beam steel plate 7 is snapped between the T-shaped groove 6 and the I-beam groove 3. A fixing member 8 is provided on one side of the front of the I-beam steel plate 7. A rectangular groove 9 is provided on the front of the connecting structure 1, which is connected to the left slot 4. The rectangular groove 9 matches the fixing member 8. The fixing member 8, the I-beam steel plate 7 and the right slot 4 are fixedly connected by hexagonal bolts 10.

[0029] In this embodiment, the tight fit between the insert block 5 and the slot 4 in the connecting mechanism initially fixes the connecting structure 1 and the steel structure body 2 in the horizontal direction. Based on this, the fixing mechanism further enhances the connection's robustness. The I-beam plate 7 is engaged between the T-slot 6 of the insert block 5 and the I-shaped slot 3 of the connecting structure 1, allowing the I-beam plate 7 to fit tightly against both, providing a larger contact area and stronger friction, effectively distributing the stress.

[0030] Working Principle: During the connection operation, the connecting structure 1 and the steel structure body 2 are first moved to a suitable installation position. Since the steel structure body 2 is symmetrically positioned at both ends of the connecting structure 1, the connections on both sides need to be processed separately. The positioning rods 11 at the four corners of both ends of the connecting structure 1 and the positioning grooves 12 at the four corners of both ends of the steel structure body 2 function. The positioning rods 11 are inserted into the positioning grooves 12, providing initial positioning and guidance, ensuring that the inserts 5 at both ends of the steel structure body 2 can accurately align with the slots 4 penetrated at both ends of the connecting structure 1. Next, the inserts 5 are forcefully inserted into the slots 4. The inserts 5 and slots 4 match, initially fixing the connecting structure 1 and the steel structure body 2 horizontally. Then, because the inserts 5 have a T-slot 6 in the middle and the connecting structure 1 has an I-shaped groove 3 in the middle, the I-beam steel plate 7 is snapped between the T-slot 6 and the I-beam groove 3. The shape of the I-beam steel plate 7 allows it to fit tightly against both, enhancing the connection strength. On one side of the front of the I-beam plate 7, the fastener 8 corresponds to the rectangular slot 9 on the front of the connecting structure 1, which is connected to and matches the left slot 4. The fastener 8 is inserted into the rectangular slot 9 to make it tightly connected with the connecting structure 1. Finally, the fastener 8, the I-beam plate 7 and the right slot 4 are fixedly connected with hexagonal bolts 10. The tightening force of the bolts makes all the components tightly connected to form a whole, completing the firm connection between the connecting structure 1 and the steel structure body 2.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
