Description

Technical Field

[0001] The utility model relates to the field of connecting devices for building steel structures, and specifically to a connecting device for building steel structures. Background Technique

[0002] There are various connecting devices for building steel structures, mainly including bolt connection, welding connection, and other special connecting devices. Bolt connection has the advantages of convenient installation, detachable, and strong load-bearing capacity, and is often used for node connections that bear large loads. Welding connection has the characteristics of high connection strength and good sealing performance, and is suitable for various steel structure connection scenarios. In addition, there are some special connecting devices, such as riveting, pin connection, and rapid connection node devices for prefabricated building steel structures, etc., to ensure the safety, reliability, and construction quality of steel structures.

[0003] The existing connecting devices for building steel structures can connect two components and multiple components. Steel structures are usually connected using bolts. Therefore, when connecting, it is necessary to align the connecting parts and the steel structure so that the bolts can smoothly pass through the predetermined through holes. However, during the alignment operation, auxiliary tools such as hammers may be used for alignment, and during the connection process, it is necessary to support the connecting device and the steel structure by hand throughout the process. This process is time-consuming and laborious, reducing the convenience of use of the connecting device for building steel structures. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a connecting device for building steel structures to solve the technical problem of time-consuming and laborious alignment operation.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A connecting device for building steel structures, including a first workpiece and a second workpiece, a connecting component is arranged between the first workpiece and the second workpiece. The connecting component includes an upper limit plate, a vertical plate is arranged at the bottom of the upper limit plate, a lower limit plate is arranged below the vertical plate, a limit groove is arranged between the upper limit plate and the lower limit plate, a connecting plate is arranged at the bottom of the lower limit plate, and a plurality of through holes are provided on the upper limit plate, the lower limit plate, and the connecting plate.

[0006] By adopting the above technical solution, when it is necessary to connect the first workpiece and the second workpiece, first insert the limit groove of the connecting component into the first cross plate. At this time, the upper limit plate and the lower limit plate limit and abut against the first cross plate. At the same time, align the through holes of the first cross plate, the upper limit plate and the lower limit plate, and fix them with bolts. Subsequently, insert the third cross plate on the second workpiece into the limit groove and fix it with bolts. At this time, align the through holes between the connecting plate, the fixed plate and the second side plate, and then pass the bolts through the through holes and connect them with nuts. This process avoids the use of auxiliary tools such as hammers and does not require long-term manual support, improving the usability of the connecting device.

[0007] Further, the first workpiece includes a fixed plate, a first cross plate is arranged on the top of the fixed plate, a second cross plate is arranged on the bottom of the fixed plate, and a first side plate is arranged between the first cross plate and the second cross plate.

[0008] By adopting the above technical solution, the fixed plate serves as the main support, ensuring the overall strength of the workpiece. At the same time, a first cross plate is arranged on the top of the fixed plate and a second cross plate is arranged on the bottom. This upper and lower symmetry not only enhances the stability of the workpiece but also facilitates connection with other components.

[0009] Further, the cross section of the limit groove is a "U" - shaped structure, and the limit groove clamps and limits the third cross plate and the first cross plate.

[0010] By adopting the above technical solution, the "U" - shaped structure provides a stable clamping space for the third cross plate and the first cross plate. When the third cross plate and the first cross plate are inserted into the limit groove, they can be firmly limited and fixed, thus ensuring the stability of the connection.

[0011] Further, the second workpiece includes a second side plate, a third cross plate is arranged on the top of the second side plate, and a fourth cross plate is arranged on the bottom of the second side plate.

[0012] By adopting the above technical solution, the second workpiece reflects the integrity of its structure. With the second side plate as the main support, the overall strength of the workpiece is ensured. At the same time, a third cross plate is arranged on the top of the second side plate and a fourth cross plate is arranged on the bottom. This upper and lower symmetry not only enhances the stability of the workpiece but also facilitates connection with other components.

[0013] Further, a plurality of the through holes are arranged in a rectangular array for providing bolt connection points.

[0014] By adopting the above technical solution, the rectangular array arrangement of bolt connections provides clear points. This arrangement ensures the alignment accuracy during the connection process, enabling the bolts to smoothly pass through the through holes and tightly cooperate with the nuts, thereby enhancing the stability of the connection.

[0015] Furthermore, the upper limit plate, the lower limit plate and the vertical plate are all made of carbon steel.

[0016] By adopting the above technical solution, the carbon steel material ensures that the connecting component has excellent mechanical properties and strength. The carbon steel material has high strength, high hardness and good wear resistance, enabling the upper limit plate, the lower limit plate and the vertical plate to withstand large external forces and pressures and not be easily deformed or damaged.

[0017] Furthermore, the fixed plate and the first workpiece are fixedly connected by welding.

[0018] By adopting the above technical solution, the welded fixed connection ensures the connection strength and stability between the two. As a firm connection method, welding can tightly combine the fixed plate with other parts of the first workpiece to form a whole, thereby effectively resisting external forces and pressures and ensuring the stability of the structure.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] With the connecting component of the present utility model, when it is necessary to connect the first workpiece and the second workpiece, first, insert the limit slot of the connecting component into the first cross plate. At this time, the upper limit plate and the lower limit plate limit and abut against the first cross plate. At the same time, align the through holes of the first cross plate, the upper limit plate and the lower limit plate, and fix them with bolts. Subsequently, insert the third cross plate on the second workpiece into the limit slot and fix it with bolts. At this time, align the through holes between the connecting plate, the fixed plate and the second side plate, and then pass the bolts through the through holes and connect them with nuts. This process avoids the use of auxiliary tools such as hammers and does not require long-term manual support, improving the convenience of use of the connecting device.

[0029] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0030] A connecting device for building steel structures, as Figures 1 - 4As shown in the figure, it includes a first workpiece 1 and a second workpiece 2. A connecting component 3 is arranged between the first workpiece 1 and the second workpiece 2. The connecting component 3 includes an upper limiting plate 301. A vertical plate 305 is arranged at the bottom of the upper limiting plate 301. A lower limiting plate 303 is arranged below the vertical plate 305. A limiting groove 302 is arranged between the upper limiting plate 301 and the lower limiting plate 303. A connecting plate 304 is arranged at the bottom of the lower limiting plate 303. Multiple through holes 4 are formed in the upper limiting plate 301, the lower limiting plate 303 and the connecting plate 304. When it is necessary to connect the first workpiece 1 and the second workpiece 2, first insert the limiting groove 302 of the connecting component 3 into the first cross plate 101. At this time, the upper limiting plate 301 and the lower limiting plate 303 limit and abut against the first cross plate 101. At the same time, align the through holes 4 of the first cross plate 101, the upper limiting plate 301 and the lower limiting plate 303, and fix and connect them with bolts. Subsequently, insert the third cross plate 201 on the second workpiece 2 into the limiting groove 302 and fix it with bolts. At this time, align the through holes 4 between the connecting plate 304, the fixing plate 104 and the second side plate 202, and then pass bolts through the through holes 4 and connect them with nuts. This process avoids the use of auxiliary tools such as hammers and does not require long-term manual support. It not only improves the use convenience of the connecting device, but also improves the installation practicability of the connecting device for building steel structures.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 , the first workpiece 1 includes a fixing plate 104. A first cross plate 101 is arranged at the top of the fixing plate 104. A second cross plate 103 is arranged at the bottom of the fixing plate 104. A first side plate 102 is arranged between the first cross plate 101 and the second cross plate 103. The fixing plate 104 serves as the main support, ensuring the overall strength of the workpiece. At the same time, a first cross plate 101 is arranged at the top of the fixing plate 104 and a second cross plate 103 is arranged at the bottom. This top-bottom symmetry not only enhances the stability of the workpiece, but also facilitates connection with other components. In addition, a first side plate 102 is arranged between the first cross plate 101 and the second cross plate 103, further enhancing the lateral support force of the workpiece, making the first workpiece 1 more stable and not easily deformed when bearing external forces. In summary, the first workpiece 1 first ensures the stability of its structure, and at the same time improves its stability and bearing capacity during use.

[0032] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, the cross-section of the limiting groove 302 is a "U" - shaped structure. The limiting groove 302 clamps and limits the third cross - plate 201 and the first cross - plate 101. The "U" - shaped structure provides a stable clamping space for the third cross - plate 201 and the first cross - plate 101. When the third cross - plate 201 and the first cross - plate 101 are inserted into the limiting groove 302, they can be firmly limited and fixed, thus ensuring the stability of the connection. At the same time, the "U" - shaped structure also has a certain elasticity, which can accommodate the slight deformation of the third cross - plate 201 and the first cross - plate 101 to a certain extent, thereby improving the adaptability and durability of the connection. In addition, this way of clamping and limiting simplifies the installation process and does not require complex alignment operations, further improving the usability of the connecting device for building steel structures. In summary, the "U" - shaped limiting groove 302 first provides a stable clamping and limiting effect, while enhancing the adaptability and durability of the connection and simplifying the installation process.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 , the second workpiece 2 includes a second side plate 202. A third cross - plate 201 is arranged at the top of the second side plate 202, and a fourth cross - plate 203 is arranged at the bottom of the second side plate 202. The second workpiece 2 reflects the integrity of its structure. With the second side plate 202 as the main support, the overall strength of the workpiece is ensured. At the same time, a third cross - plate 201 is arranged at the top of the second side plate 202 and a fourth cross - plate 203 is arranged at the bottom. This up - down symmetry not only enhances the stability of the workpiece but also facilitates connection with other components. The arrangement of the third cross - plate 201 and the fourth cross - plate 203 provides an additional support surface for the second workpiece 2, making it more stable when bearing external forces and not easily deformed. In addition, it also makes the installation and connection process of the second workpiece 2 more convenient because the third cross - plate 201 and the fourth cross - plate 203 can be used as positioning references, simplifying the alignment and fixing steps. In summary, the second workpiece 2 first ensures the integrity of its structure, while improving its stability and installation convenience during use.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, multiple through - holes 4 are arranged in a rectangular array to provide bolt connection points. The rectangular array arrangement of bolts provides clear points, and this arrangement ensures alignment accuracy during the connection process, enabling the bolts to smoothly pass through the through - holes 4 and tightly fit with nuts, thereby enhancing the connection stability. At the same time, the rectangular array arrangement also optimizes the space utilization rate of the connection device, enabling more connection points to be arranged within a limited area, thereby improving the connection load - bearing capacity and overall strength. In addition, it simplifies the installation process because the rectangular array arrangement makes the positions of the through - holes 4 more intuitive and easy to understand, reducing the installation difficulty and error rate. In summary, the multiple through - holes 4 arranged in a rectangular array first provide clear bolt connection points, while optimizing the space utilization rate and simplifying the installation process.

[0035] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the upper limit plate 301, the lower limit plate 303 and the vertical plate 305 are all made of carbon steel. The carbon steel material ensures that the connecting component 3 has excellent mechanical properties and strength. The carbon steel material has high strength, high hardness and good wear resistance, enabling the upper limit plate 301, the lower limit plate 303 and the vertical plate 305 to withstand large external forces and pressures, and not be easily deformed or damaged. At the same time, the carbon steel material also has good weldability and processability, facilitating the processing and assembly of the connecting component 3 during the production process. In addition, the cost of the carbon steel material is relatively low, effectively controlling the production cost of the connecting component 3, and thus reducing the cost of the overall connection device for building steel structures. In summary, using carbon steel to make the upper limit plate 301, the lower limit plate 303 and the vertical plate 305 first ensures the mechanical properties and strength of the connecting component, while reducing the production cost.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 , the fixing plate 104 and the first workpiece 1 are fixedly connected by welding. The welded fixed connection ensures the connection strength and stability between the two. As a firm connection method, welding can tightly combine the fixing plate 104 with other parts of the first workpiece 1 to form a whole, thereby effectively resisting external forces and pressures and ensuring the structural stability. At the same time, the welded connection also has good sealing performance, which can prevent the leakage of gas or liquid, improving the service performance of the first workpiece 1. In addition, the welded connection also simplifies the production process, improves the production efficiency and reduces the production cost. In summary, the fixing plate 104 and the first workpiece 1 being fixedly connected by welding first ensures the connection strength and stability, while improving the sealing performance and production efficiency.

[0037] The implementation principle of the present utility model is as follows: When it is necessary to connect the first workpiece 1 and the second workpiece 2, first insert the limiting groove 302 of the connecting component 3 into the first cross plate 101. At this time, the upper limiting plate 301 and the lower limiting plate 303 limit and abut against the first cross plate 101. Then align the through holes 4 of the first cross plate 101, the upper limiting plate 301, and the lower limiting plate 303, and fix them with bolts. Subsequently, insert the third cross plate 201 on the second workpiece 2 into the limiting groove 302 and fix it with bolts. At this time, the through holes 4 between the connecting plate 304, the fixing plate 104, and the second side plate 202 are in an aligned state. Then pass bolts through the through holes 4 and connect them with nuts. At this time, the connection operation between the first workpiece 1 and the second workpiece 2 is completed. During this connection process, when the connecting device for steel structures is being connected, it avoids the alignment operation with the aid of auxiliary tools such as hammers during the alignment operation, and eliminates the operation of holding the connecting device and the steel structure by hand during the connection process, improving the usability of the connecting device for building steel structures.
