Description

Technical Field

[0001] This utility model relates to the field of bulb flat steel technology, specifically a bulb flat steel with an embedded mounting groove. Background Technology

[0002] Bulb flat steel is a type of hot-rolled steel with an asymmetrical cross-section, named for the spherical flange on one side. Its shape resembles a combination of the letter "L" and a semicircle. During production, a specific rolling process involves multiple passes of stretching and shaping on a rolling mill to precisely control the dimensions and shape. This steel possesses high strength and excellent bending resistance. The spherical flange enhances the moment of inertia of the cross-section, giving it a greater load-bearing capacity than ordinary flat steel of the same weight. Furthermore, it has good surface quality, high dimensional accuracy, and is easy to weld and install. In shipbuilding, bulb flat steel is used in critical components such as hull ribs and beams to ensure the stability and safety of the ship's structure. In bridge construction, it serves as a crucial component of the supporting structure, bearing enormous loads. The machinery manufacturing industry also frequently utilizes its properties to manufacture various robust and durable mechanical parts.

[0003] For example, patent CN104108081B discloses a tooling for butt welding of bulb flat steel and flat steel. It includes bulb flat steel, flat steel and clamp. The bulb flat steel and flat steel are arranged left and right. The bulb flat steel includes a front bulb flat steel and a rear bulb flat steel arranged front and back. The rear end of the front bulb flat steel and the front end of the rear bulb flat steel are respectively embedded in the clamping plate in front of the clamp and the clamping plate in rear of the clamp. The right end of the locking bolt of the clamp abuts against the left side of the bulb flat steel, so that the lateral position of the rear end of the front bulb flat steel and the front end of the rear bulb flat steel are consistent, and the rear end of the front bulb flat steel and the front end of the rear bulb flat steel are welded together. However, in the current process, when the two bulb flats are assembled using bolts, precise drilling is required on the bulb flats. During installation, the bolts must be repeatedly aligned and tightened. The entire process involves many steps, which not only consumes a lot of manpower and time, but also requires a high level of skill from the installers. The installation efficiency is extremely low. Furthermore, during subsequent use, due to factors such as vibration and load changes, stress concentration is easily formed at the bolt connection points when under stress, making it difficult to achieve uniform force transmission between the bulb flats. This results in a serious lack of overall structural stability, which greatly weakens the load-bearing capacity and safety of the bulb flat steel composite structure.

[0004] Therefore, in order to solve such problems, we propose a bulb flat steel with an embedded mounting groove. Utility Model Content

[0005] The purpose of this utility model is to provide a bulb flat steel with an embedded mounting groove to solve the problem mentioned in the background art. In the process of assembling two bulb flat steels by bolts alone, precise drilling is required on the bulb flat steels. During installation, the bolts must be repeatedly aligned and tightened. The whole process is complicated, which not only consumes a lot of manpower and time, but also requires a high level of skill from the installers. The installation efficiency is extremely low. Moreover, in subsequent use, due to factors such as vibration and load changes, stress concentration is easily formed at the bolt connection point when under force, making it difficult to achieve uniform force transmission between the bulb flat steels. This results in a serious lack of overall structural stability and greatly weakens the load-bearing capacity and safety of the bulb flat steel composite structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bulb flat steel with an embedded mounting groove, comprising a first steel plate and a second steel plate disposed on the right side of the first steel plate. T-shaped plates are uniformly fixedly connected to the outer right side of the first steel plate. A groove is provided on the right side of the bottom of the T-shaped plate. A rotating shaft is rotatably connected in the groove. A deflection plate is fixedly connected to the rotating shaft. T-shaped grooves are uniformly provided on the outer left side of the second steel plate. An inclined groove is provided on the right side of the bottom of the T-shaped groove. A first fixing bolt is threadedly connected to the bottom of the second steel plate, and the first fixing bolt is located directly below the inclined groove.

[0007] Furthermore, a first spherical flat member is fixedly connected to the rear of the top of the first steel plate, and a guide rod is fixedly connected to the right side of the first spherical flat member.

[0008] Furthermore, a second spherical flat member is fixedly connected to the rear of the top of the second steel plate, and a round hole is provided on the left outer wall of the second spherical flat member.

[0009] Furthermore, the length of the guide rod is the same as the length of the circular hole, and the first and second spherical flat pieces are positioned and installed by means of the guide rod and the circular hole.

[0010] Furthermore, square grooves are provided at both ends of the left outer wall of the second steel plate, and square plates are fixedly connected to both ends of the right outer wall of the first steel plate, with second fixing bolts threaded onto the square plates.

[0011] Furthermore, the square plate is located within the square groove, and the square groove and the square plate are fixedly connected by a second fixing bolt, and both the first fixing bolt and the second fixing bolt are countersunk bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the ball flat steel with embedded mounting groove adopts a novel structural design, the specific details of which are as follows:

[0013] (1) The ball flat steel with embedded mounting groove, through the embedded mating structure of T-shaped plate and T-shaped groove, only needs to be aligned and inserted into T-shaped groove during installation. The rotation characteristics of the deflection plate around the rotating shaft form a linkage lock with the inclined groove to complete the initial fixation. This avoids the tedious process of repeatedly aligning the holes and tightening the bolts one by one in the traditional bolt connection, significantly reducing the dependence on the operating experience of the installers and improving the installation efficiency by a factor of magnitude. After the deflection plate rotates through the rotating shaft, it is inserted into the inclined groove. The inclined structure distributes the load to the contact surface of the T-shaped plate and T-shaped groove, avoiding the stress concentration problem of the traditional bolt connection point and realizing the uniform transmission of force between the ball flat steel. By inserting the square plate into the square groove and locking it with the second fixing bolt, a double connection structure of surface contact and bolt fixation is formed, which further strengthens the lateral stability of the first steel plate and the second steel plate and improves the overall structure's resistance to vibration and load changes.

[0014] (2) The ball flat steel with embedded mounting groove has an axial limiting and guiding structure formed by the guide rod of the first ball flat piece and the round hole of the second ball flat piece. The two are precisely matched in size. During the installation process, the guide rod can be directly inserted into the round hole. Through the "pin hole positioning" mechanism, on the one hand, it helps the first steel plate and the second steel plate to quickly align, greatly reducing the difficulty of installation alignment. On the other hand, it effectively restricts the relative displacement of the two steel plates in the vertical direction, eliminating the problem of reduced load-bearing capacity caused by installation misalignment from the root, and significantly improving the installation accuracy and structural reliability of the ball flat steel assembly.

[0015] Furthermore, both the first and second fixing bolts adopt a countersunk bolt design, in which the bolt head can be fully embedded in the surface of the component. This design not only avoids interference with the installation of other components caused by the protrusion of the traditional bolt head, but also effectively reduces the risk of stress concentration by eliminating the surface protrusion structure, thereby simultaneously improving the aesthetics and safety performance of the structure.

[0023] 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.

[0024] This utility model provides the following technical solution: a ball flat steel with an embedded mounting groove.

[0025] Example 1: A bulb flat steel bar with an embedded mounting groove, using components such as a T-shaped plate 12, a T-shaped groove 22, a deflection plate 122, and an inclined groove 221 to assemble and fix the first steel plate 1 and the second steel plate 2. This avoids the problems of relying solely on bolts to assemble two bulb flat steel bars, which requires precise drilling on the bulb flat steel bars, repeated alignment and tightening of bolts during installation, and numerous steps. This process not only consumes a lot of manpower and time but also requires a high level of skill from the installers, resulting in extremely low installation efficiency. Figure 1 - Figure 4 As shown, a bulb flat steel with an embedded mounting groove includes a first steel plate 1 and a second steel plate 2 disposed on the right side of the first steel plate 1. T-shaped plates 12 are uniformly fixedly connected to the outer right side of the first steel plate 1. A groove is formed on the right side of the bottom of the T-shaped plate 12, and a rotating shaft 121 is rotatably connected within the groove. A deflection plate 122 is fixedly connected to the rotating shaft 121. T-shaped grooves 22 are uniformly formed on the outer left side of the second steel plate 2, and an inclined groove 221 is formed on the right side of the bottom of the T-shaped groove 22. The bottom of each of the two steel plates 2 is threaded with a first fixing bolt 24, and the first fixing bolt 24 is located directly below the inclined groove 221. The two ends of the left outer wall of the second steel plate 2 are provided with square grooves 23. The two ends of the right outer wall of the first steel plate 1 are fixedly connected with square plates 3. The square plates 3 are threaded with a second fixing bolt 31. The square plates 3 are located in the square grooves 23, and the square grooves 23 and the square plates 3 are fixedly connected by the second fixing bolts 31. Both the first fixing bolt 24 and the second fixing bolt 31 are countersunk bolts.

[0026] Align the T-shaped plate 12 on the right side of the first steel plate 1 with the T-shaped groove 22 on the left side of the second steel plate 2 and insert it vertically. The shape of the T-shaped cross section allows for initial lateral positioning without the need for precise drilling on the steel plate beforehand. The rotating shaft 121 is rotatably connected to the groove on the bottom right side of the T-shaped plate 12. The deflection plate 122 fixed on the rotating shaft 121 can rotate around the rotating shaft 121 after insertion. When the T-shaped plate 12 is fully inserted into the T-shaped groove 22, rotate the deflection plate 122 so that it is embedded in the inclined groove 221 at the bottom right side of the T-shaped groove 22. The inclined angle of the inclined groove 221 creates a "wedge effect", which secures the first steel plate 1 and the second steel plate 2. Locked horizontally, initial fixation is completed. The first fixing bolt 24 is threadedly connected to the bottom of the second steel plate 2 and located directly below the inclined groove 221. When disassembling, when the first fixing bolt 24 is turned, upward pressure can be applied to the deflection plate 122 through the bottom of the inclined groove 221, which facilitates subsequent disassembly. The square plates 3 at both ends of the right side of the first steel plate 1 are inserted into the square grooves 23 at both ends of the left side of the second steel plate 2 and locked by the second fixing bolt 31. The surface contact structure between the square plate 3 and the square groove 23 can bear the lateral shear force. Together with the second fixing bolt 31, it forms a four-way limit in the lower, left and right directions, which strengthens the stability of the connection and reduces the shear force directly borne by the bolt.

[0027] Example 2: Unlike Example 1, the combined structure of square plate 3, square channel 23, and second fixing bolt 31 strengthens the stability of the assembly between the first steel plate 1 and the second steel plate 2. This prevents stress concentration at the bolt connection points due to vibration, load changes, etc., which would hinder the uniform transfer of force between the bulb flat steel bars, resulting in insufficient overall structural stability and significantly weakening the load-bearing capacity and safety of the bulb flat steel composite structure. Figures 5-6 As shown, a first spherical flat piece 11 is fixedly connected to the rear of the top of the first steel plate 1, and a guide rod 111 is fixedly connected to the right side of the first spherical flat piece 11. A second spherical flat piece 21 is fixedly connected to the rear of the top of the second steel plate 2. A circular hole 211 is provided on the outer left side of the second spherical flat piece 21. The length of the guide rod 111 is the same as the length of the circular hole 211. The first spherical flat piece 11 and the second spherical flat piece 21 are limited and installed by the guide rod 111 and the circular hole 211.

[0028] The first spherical flat member 11 at the top rear of the first steel plate 1 has a fixed guide rod 111 on the right side, and the second spherical flat member 21 at the top rear of the second steel plate 2 has a round hole 211 on the left side. The two are the same size. During installation, the guide rod 111 is inserted into the round hole 211 to form an axial limiting and guiding structure similar to a pin and a pin hole. This can help the first steel plate 1 and the second steel plate 2 to quickly align, avoid misalignment that would prevent the T-shaped plate 12 from being inserted into the T-shaped groove 22, and limit the relative displacement of the two steel plates in the vertical direction. This ensures the installation accuracy of the spherical flat steel assembly and avoids weakening the load-bearing capacity due to installation deviation. The first fixing bolt 24 and the second fixing bolt 31 are both countersunk bolts. Their heads can be completely embedded in the surface of the component, eliminating the protrusion of the traditional bolt head. This avoids interference with the installation of other components and reduces surface stress concentration points, improving the aesthetics and safety of the structure.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
