Description

Technical Field

[0001] The utility model relates to the technical field of steel structure splicing, in particular to a steel structure splicing mechanism. Background Art

[0002] Steel structure is a building made of steel. It is one of the most common structural forms in current construction projects. It has the characteristics of high strength, light weight, energy saving and environmental protection. It is used in many large factories, high-rise buildings, bridges and other facilities.

[0003] Steel structure splicing mechanism is a process or process of connecting prefabricated steel structure components, which includes factors such as prefabricated components, connecting two parts, and splicing technology. It involves multiple links and elements and is a complex process.

[0004] In the existing technology, the connection of steel structures may require a professional construction team and complex connection techniques, and the direct connection between two steel structures is not tight enough, and the strength of the connection is insufficient. For this reason, we propose a steel structure splicing mechanism. Utility Model Content

[0005] In view of the above problems, the utility model provides a steel structure splicing mechanism, which has a more stable connection.

[0006] The technical solution of the utility model is: it includes a first connecting member, a second connecting member is provided on one side of the first connecting member, a toothed slot is opened on the inner side of the first connecting member, a toothed block is fixedly connected to one end of the second connecting member close to the first connecting member, a toothed block is slidably connected to the inside of the toothed slot, a fixed hexagonal screw is threaded through the inside of the toothed block, a fixed hexagonal screw is threaded through the inside of the first connecting member, a hexagonal nut is installed on the outside of the fixed hexagonal screw at the bottom of the first connecting member, the fixed hexagonal screw is threaded inside the hexagonal nut, and a rotating cover is rotatably connected to the top of the second connecting member, and a countersunk hole is opened inside the rotating cover.

[0007] The connection of steel structures may require a professional construction team and complex connection techniques, and the direct connection of two steel structures is not tight enough, and the strength of the connection is insufficient. Therefore, the multi-layer connection of toothed blocks and toothed slots makes the connection of steel structures more stable and convenient. At the same time, the rotating cover plate shields and protects the connection. The use of fixed hexagonal screws further enhances the strength and stability of the steel structure connection and increases the convenience of steel structure connection.

[0008] In a further technical solution, a protective shell is slidably connected to the outer side of the second connecting member, a phase change material is installed inside the protective shell, a limiting hole is provided on the inner side of the protective shell near the fixed hexagonal screw, a baffle is fixedly connected to the bottom of the first connecting member near the protective shell, and a spring rod is fixedly connected to the bottom of the fixed hexagonal screw.

[0009] When steel structures are connected, if high temperatures are encountered, the joints are prone to deformation due to the high temperatures, causing the entire steel structure to collapse. Therefore, by putting a protective shell on the joints, not only can the joints be shielded and protected, but the phase change material will begin to change phase when exposed to heat, absorbing a large amount of heat, thereby slowing down the time it takes for the joints to deform due to high temperatures.

[0010] In a further technical solution, a trapezoidal plug is provided on one side of the toothed block close to the toothed slot, and a fixing groove is provided on one side of the toothed slot close to the toothed block, and a trapezoidal plug is slidably connected inside the fixing groove.

[0011] When the connection is used for a long time, the connection may become loose. Therefore, by cooperating with the trapezoidal plug and the fixing groove, the loosening of the connection due to long-term use is reduced, and the safety during use is enhanced.

[0012] In a further technical solution, a fixed slot is opened in the middle of the baffle, a spring buckle is fixedly connected to one end of the bottom of the protective shell close to the fixed slot, and a spring buckle is slidably connected inside the fixed slot.

[0013] When the protective shell is brought close to the baffle, the limitation of the spring rod and the limiting hole may not be stable enough and may fall off when encountering a large force. Therefore, the spring buckle is clamped on the baffle to make the connection between the protective shell and the baffle more stable, increasing the stability of the protective shell during operation.

[0014] In a further technical solution, a buffer plate is installed at one end of the toothed block close to the first connecting member, and the buffer plate is made of shock-absorbing material.

[0015] After the steel structure is connected, it may encounter some vibrations and collisions, which may affect the connection effect. The buffer plate can filter and buffer these vibrations, thereby increasing the seismic resistance of the steel structure during connection.

[0016] In a further technical solution, a lifting buckle is fixed to the top of the rotating cover.

[0017] By opening the rotating cover through the lifting buckle, the efficiency of opening and closing the rotating cover can be increased.

[0018] In a further technical solution, a handle is fixedly connected to one side of the protective shell.

[0019] Pulling the handle can make the protective case slide more conveniently and efficiently.

[0020] The beneficial effects of the utility model are:

[0021] 1. The connection of steel structures may require a professional construction team and complex connection techniques. In addition, the direct connection of two steel structures may not be tight enough, and the strength of the connection is insufficient. Therefore, the multi-layer connection of the toothed block and the toothed slot makes the connection of the steel structure more stable and convenient. At the same time, the rotating cover is used to shield and protect the connection. The use of fixed hexagonal screws further enhances the strength and stability of the steel structure connection and increases the convenience of steel structure connection.

[0022] 2. When connecting steel structures, if high temperatures are encountered, the joints are prone to deformation due to high temperatures, causing the entire steel structure to collapse. Therefore, by putting a protective shell on the joints, not only can the joints be shielded and protected, but the phase change material will begin to change phase when heated, absorbing a large amount of heat, slowing down the time it takes for the joints to deform due to high temperatures.

[0029] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0030] Example:

[0031] like Figures 1-4As shown, it includes a first connecting member 1, a second connecting member 11 is provided on one side of the first connecting member 1, a toothed slot 15 is opened on the inner side of the first connecting member 1, and a toothed block 14 is fixed to one end of the second connecting member 1 close to the first connecting member 1, and a toothed block 14 is slidably connected inside the toothed slot 15, and a fixed hexagonal screw 13 is threadedly connected inside the toothed block 14, and a fixed hexagonal screw 13 is threadedly connected inside the first connecting member 1, a hexagonal nut 16 is installed on the outside of the fixed hexagonal screw 13 at the bottom of the first connecting member 1, and the fixed hexagonal screw 13 is threadedly connected inside the hexagonal nut 16, and the fixed hexagonal screw 13 is threadedly connected inside the hexagonal nut 16, and the second connecting member 11 is rotatably connected to the top of the rotating cover 12, and a countersunk hole 17 is opened inside the rotating cover 12. When working, place the first connecting piece 1 at the position where it needs to be installed, then lift the second connecting piece 11 and keep it level with the first connecting piece 1, and then make the toothed block 14 at the end of the second connecting piece 11 enter the toothed slot 15 to achieve connection. At this time, rotate the rotating cover 12 on the top of the second connecting piece 11 to cover the top of the toothed slot 15, and rotate the fixed hexagonal screw 13 to enter the countersunk hole 17, the toothed block 14, and the hexagonal nut 16 to connect the second connecting piece 11 to the first connecting piece 1. This step of connecting the steel structure may require a professional construction team and complex connection skills, and the two steel structures are not directly connected tightly enough, and the strength of the connection is insufficient. Therefore, the multi-layer connection of the toothed block 14 and the toothed slot 15 makes the connection of the steel structure more stable and convenient. At the same time, the rotating cover 12 shields and protects the connection. The use of fixing the hexagonal screw 13 further enhances the strength and stability of the steel structure connection and increases the convenience when connecting the steel structure.

[0032] like Figure 1-Figure 2 As shown, the outer side of the second connecting member 11 is slidably connected to the protective shell 2, and the protective shell 2 is installed with a phase change material 21. The inner side of the protective shell 2 is provided with a limiting hole 22 near the fixing hexagonal screw 13. The bottom of the first connecting member 1 is fixed with a baffle 23 near the protective shell 2, and the bottom of the fixing hexagonal screw 13 is fixed with a spring rod 24. When working, the phase change material 21 is first injected into the protective shell 2, and then the protective shell 2 is put on the outer side of the second connecting member 11. After the second connecting member 11 is connected to the first connecting member 1, the protective shell 2 and the baffle 2 are moved. 3 fits, at this time, the spring rod 24 is first squeezed and contracted by the protective shell 2. When the protective shell 2 fits onto the baffle 23, the spring rod 24 rebounds and enters the limiting hole 22 to fix the protective shell 2. During this step, when the steel structure is connected, if it encounters high temperature, the connection is prone to deformation due to high temperature, causing the entire steel structure to collapse. Therefore, by putting the protective shell 2 on the connection, not only can the connection be shielded and protected, but the phase change material 21 will begin to phase change when heated, absorbing a large amount of heat, thereby slowing down the deformation time of the connection due to high temperature.

[0033] like Figure 4 As shown, a trapezoidal plug iron 31 is provided on the side of the tooth-shaped card block 14 near the tooth-shaped card slot 15, and a fixing groove 3 is provided on the side of the tooth-shaped card slot 15 near the tooth-shaped card block 14. The trapezoidal plug iron 31 is slidably connected inside the fixing groove 3. When working, after the tooth-shaped card slot 15 and the tooth-shaped card block 14 are connected, a fixing groove 3 will be formed between the tooth-shaped card slot 15 and the tooth-shaped card block 14. At this time, the trapezoidal plug iron 31 is hammered into the fixing groove 3 to make the connection between the tooth-shaped card block 14 and the tooth-shaped card slot 15 tighter. This step may cause the connection to become loose when the connection is used for a long time. Therefore, the cooperation between the trapezoidal plug iron 31 and the fixing groove 3 reduces the looseness of the connection due to long-term use, thereby enhancing safety during use.

[0034] like Figure 1 As shown, a fixed slot 4 is provided in the middle of the baffle 23, and a spring buckle 41 is fixed to one end of the bottom of the protective shell 2 near the fixed slot 4, and the spring buckle 41 is slidably connected inside the fixed slot 4. During operation, when the protective shell 2 is brought close to the baffle 23, the spring buckle 41 will enter the fixed slot 4 in the middle of the baffle 23 to connect the protective shell 2 and the baffle 23. In this step, when the protective shell 2 is brought close to the baffle 23, the limiting position of the spring rod 24 and the limiting hole 22 may not be stable enough and may fall off when encountering a large force. Therefore, the spring buckle 41 is stuck on the baffle 23, so that the connection between the protective shell 2 and the baffle 23 is more stable, which increases the stability of the protective shell 2 during operation.

[0035] like Figure 4 As shown, a buffer plate 5 is installed at one end of the tooth-shaped block 14 near the first connecting member 1. The buffer plate 5 is made of shock-absorbing material. When the tooth-shaped block 14 is installed inside the tooth-shaped slot 15 during operation, the buffer plate 5 is installed between the top of the tooth-shaped block 14 and the first connecting member 1. After the steel structure is connected, this step may encounter some vibrations and expansions. These collisions may affect the connection effect. The buffer plate 5 is used to filter and buffer these vibrations, thereby increasing the seismic resistance of the steel structure during connection.

[0036] like Figure 3 As shown, a lifting buckle 6 is fixedly connected to the top of the rotating cover 12. When the rotating cover 12 needs to be opened by rotating during operation, the lifting buckle 6 is pulled to make the opening more convenient. By opening the rotating cover 12 through the lifting buckle 6, the efficiency of opening and closing the rotating cover 12 can be increased.

[0037] like Figure 1 As shown, a handle 7 is fixedly connected to one side of the protective shell 2. During operation, when the protective shell 2 needs to be slid, pulling the handle 7 can make the sliding of the protective shell 2 more convenient and more efficient.

[0038] The working principle of the above technical solution is as follows:

[0039] Place the first connector 1 at the location where it needs to be installed, then lift the second connector 11 and keep it level with the first connector 1, then make the toothed block 14 at the end of the second connector 11 enter the toothed slot 15 to achieve connection, then rotate the rotating cover 12 on the top of the second connector 11 to cover the top of the toothed slot 15, rotate and fix the hexagonal screw 13 to enter the countersunk hole 17, the toothed block 14, and the hexagonal nut 16 to connect the second connector 11 to the first connector 1. The connection of the steel structure in this step may require a professional construction team and complex connection skills, and the two steel structures may not be directly connected tightly enough, and the strength of the connection is insufficient, so a multi-layer connection is made through the toothed block 14 and the toothed slot 15. , making the connection of the steel structure more stable and convenient, while rotating the cover plate 12 to shield and protect the connection, and the use of the fixed hexagonal screws 13 further enhances the strength and stability of the steel structure connection, and increases the convenience of steel structure connection. The phase change material 21 is injected into the protective shell 2, and then the protective shell 2 is put on the outside of the second connecting piece 11. After the second connecting piece 11 is connected to the first connecting piece 1, the protective shell 2 is moved to fit with the baffle 23. At this time, the spring rod 24 is first squeezed and contracted by the protective shell 2. When the protective shell 2 is fitted to the baffle 23, the spring rod 24 rebounds into the limiting hole 22 to fix the protective shell 2. When this step is connected to the steel structure, if high temperature is encountered, the connection is prone to deformation due to high temperature. The whole steel structure will collapse. Therefore, by putting the protective shell 2 on the connection, not only can the connection be shielded and protected, but the phase change material 21 will begin to change phase when heated, absorb a large amount of heat, and slow down the time for the connection to be deformed due to high temperature. After the tooth-shaped slot 15 is connected to the tooth-shaped block 14, a fixed slot 3 will be formed between the tooth-shaped slot 15 and the tooth-shaped block 14. At this time, the trapezoidal plug 31 is hammered into the fixed slot 3 to make the connection between the tooth-shaped block 14 and the tooth-shaped slot 15 tighter. This step may cause the connection to become loose when the connection is used for a long time. Therefore, the cooperation between the trapezoidal plug 31 and the fixed slot 3 reduces the looseness of the connection due to long-term use, and enhances the safety during use. Safety, when the protective shell 2 is brought close to the baffle 23, the spring buckle 41 will enter the fixed card slot 4 in the middle of the baffle 23 to connect the protective shell 2 and the baffle 23. In this step, when the protective shell 2 is brought close to the baffle 23, the spring rod 24 and the limiting hole 22 may not be stable enough and may fall off when encountering a large force. Therefore, the spring buckle 41 is stuck on the baffle 23, so that the connection between the protective shell 2 and the baffle 23 is more stable, which increases the stability of the protective shell 2 during work. When the toothed block 14 is installed in the toothed slot 15, the buffer plate 5 is installed between the top of the toothed block 14 and the first connecting member 1. This step may encounter some vibration and expansion after the steel structure is connected. These collisions may affect the connection effect.The buffer plate 5 filters and buffers these vibrations, increasing the seismic resistance of the steel structure connection. A pull-up buckle 6 is fixed to the top of the rotating cover 12. When the rotating cover 12 needs to be opened by rotating during operation, the pull-up buckle 6 is pulled to make opening more convenient. Opening the rotating cover 12 by pulling the pull-up buckle 6 can increase the efficiency of opening and closing the rotating cover 12. When the protective shell 2 needs to be slid, the handle 7 is pulled, making the sliding of the protective shell 2 more convenient and efficient.

Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
