Description

Technical Field

[0001] This utility model relates to the field of steel structure assembly technology, specifically a steel structure assembly node. Background Technology

[0002] During the installation of steel structure columns, two connecting steel plates are welded to the bottom sides of the upper column. Then, four more corresponding connecting steel plates are welded to the bottom column. The connecting plates are then bolted together, pre-fixing the upper and lower columns. After the other steel components are installed, the upper and lower columns are welded together, and finally, the connecting steel plates are removed to complete the installation. The existing steel structure assembly nodes require a large number of bolts to fix the connecting plates and connecting steel plates, which affects the overall installation efficiency. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a steel structure assembly node to solve the technical problem that tightening a large number of bolts affects the overall installation efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a steel structure assembly node, including an upper steel column and a lower steel column. Upper connecting steel plates are fixedly connected to both sides of the bottom of the upper steel column, and lower connecting steel plates are fixedly connected to both sides of the top of the lower steel column. The upper and lower connecting steel plates are connected to a wedge plate via a fixing clamp. A pressure-bearing structure for clamping is provided on the upper connecting steel plate. An outer hole is provided on the fixing clamp, and an inner hole is provided on the lower connecting steel plate. A clamping structure for clamping is fixedly connected inside the fixing clamp.

[0005] By adopting the above technical solution, traditional steel structure assembly nodes usually require a large number of bolts to connect the upper and lower steel columns, which takes a lot of time and manpower to tighten the bolts. By using the combination of fixing clamps and wedges, a fast and simple connection method is achieved, which greatly shortens the installation time and reduces labor costs.

[0006] Furthermore, the pressure-bearing structure includes a first pressure-bearing groove, which is arranged in a triangular shape.

[0007] By adopting the above technical solution, the first pressure groove of the triangular structure enhances the stability and fastening force of the connection. When the clamping structure of the fixing clamp is pressed into the first pressure groove, due to the characteristics of the triangular structure, the clamping structure can fit tightly against the inner wall of the first pressure groove to form a stable connection.

[0008] Furthermore, the clamping structure includes a first clamping block, which is arranged in a triangular shape.

[0009] By adopting the above technical solution, the first pressing block with the triangular structure and the first pressure groove form a perfect fit. When the first pressing block is pressed into the first pressure groove, since both are triangular structures, they can fit together tightly to form a stable and reliable connection.

[0010] Furthermore, both the outer and inner holes are keyway-type structures, and the outer and inner holes are used for the wedge plate to be inserted.

[0011] By adopting the above technical solution, the outer and inner holes of the keyway structure provide a stable wedging foundation for the wedge plate, improve the firmness of the connection, and ensure that the connection remains stable when subjected to external force, without loosening or falling off.

[0012] Furthermore, one side of the fixing clamp has a slot for welding, and the slot is arranged in an arc shape.

[0013] By adopting the above technical solution, the arc-shaped slot provides convenience for welding operations, and the presence of the slot also avoids interference from the fixing clamp on the welding operation, thus improving the quality and efficiency of welding.

[0014] Furthermore, the pressure-bearing structure includes a second pressure-bearing groove, which is rectangular in shape and has a rounded bottom.

[0015] By adopting the above technical solution, the second pressure groove of the rectangular structure provides a larger contact area and a more stable force environment for the clamping structure, so that the assembly node can maintain its shape and position more stably when subjected to external force, and will not loosen or fall off.

[0016] Furthermore, the clamping structure includes a second clamping block, which is arranged in a cylindrical shape.

[0017] By adopting the above technical solution, the cylindrical second clamping block can better adapt to and match the shape of the second pressure groove, improving the stability and reliability of the connection, and enabling the assembly node to maintain its shape and position more stably when subjected to external forces.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model, by setting up a fixing clamp, wedge plate, pressure-bearing structure and clamping structure, utilizes the cooperation of the triangular first pressure groove and the first clamping block and the cylindrical second clamping block and the bottom arc of the rectangular pressure groove to effectively adapt to the positional deviation between the pressure groove of the upper connecting steel plate and the inner hole, ensuring that the inner hole and the outer hole are aligned. Thus, by hammering in the wedge plate, a quick and reliable temporary fixation of the upper and lower steel columns is achieved, further improving the flexibility and fault tolerance of the installation. After all components are installed in place, the upper and lower steel columns can be smoothly welded together, ensuring the stability and reliability of the entire steel structure assembly node, while reducing installation time and improving installation efficiency.

[0020] 2. By setting up an empty slot, this utility model provides welders with ample welding space and operational convenience, enabling the welding process to proceed more smoothly and improving welding efficiency and quality. After welding is completed, the entire installation process can be completed by simply removing the connecting steel plates, fixing clamps, and wedge plates. This not only makes the operation simple but also avoids the impact of redundant components on the structure, ensuring the neatness and aesthetics of the entire steel structure assembly node.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1:

[0029] A type of steel structure assembly node, such as Figures 1-4 As shown, the assembly includes an upper steel column 1 and a lower steel column 2. Upper connecting steel plates 3 are fixedly connected to both sides of the bottom of the upper steel column 1, and lower connecting steel plates 4 are fixedly connected to both sides of the top of the lower steel column 2. The upper connecting steel plates 3 and 4 are connected to a wedge plate 6 via a fixing clamp 5. A pressure-bearing structure 7 for clamping is provided on the upper connecting steel plate 3. An outer hole 10 is provided on the fixing clamp 5, and an inner hole 8 is provided on the lower connecting steel plate 4. A clamping structure 9 for clamping is fixedly connected inside the fixing clamp 5. The upper connecting steel plates 3 and 4 are tightly connected to the wedge plate 6 via the fixing clamp 5, forming a stable assembly node. The clamping structure 9 fits tightly with the pressure-bearing structure 7 on the connecting steel plate 3, ensuring the firmness of the connection. The wedging of the wedge plate 6 further enhances the fastening force of the connection, enabling the entire assembly node to remain stable when subjected to external forces. The design of the fixing clamp 5 and the wedge plate 6 also allows the entire assembly node to have a certain adjustment space during installation, which can cope with certain installation deviations and position changes. The fixing clamp 5 and the wedge plate 6 provide convenience for welding operations, making the welding work smoother. After welding is completed, the fixing clamp 5 and the wedge plate 6 can be easily removed without affecting the entire steel structure.

[0030] See Figure 1 , Figure 2 and Figure 3 The pressure-bearing structure 7 includes a first pressure-bearing groove 71, which is arranged in a triangular shape. In the actual installation process, due to the influence of various factors, there may be slight deviations or positional changes between the upper connecting steel plate 3 and the lower connecting steel plate 4. The triangular structure of the first pressure-bearing groove 71 can allow for a certain deviation, so that the pressing structure 9 can automatically adjust its position when pressed in, forming a tight fit with the first pressure-bearing groove 71.

[0031] See Figure 1 , Figure 2 and Figure 3 The clamping structure 9 includes a first clamping block 91, which is triangular in shape. This triangular first clamping block 91 also has guiding and self-positioning functions. During installation, due to various factors, slight deviations or positional changes may occur between the fixing clamp 5 and the upper connecting steel plate 3. When the triangular first clamping block 91 is pressed into the first pressure groove 71, it can automatically adjust its position to form a tight fit with the first pressure groove 71, thus achieving automatic guiding and self-positioning. This function reduces the difficulty and requirements of installation, and improves installation efficiency and success rate.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Both the outer hole 10 and the inner hole 8 are keyway-type structures. The outer hole 10 and the inner hole 8 are used for the wedge plate 6 to be wedged in. Since the keyway-type structure has good shear resistance, making the outer hole 10 and the inner hole 8 into a keyway-type structure can enhance the stability and reliability of the entire assembly node when subjected to shear force, so that the assembly node can maintain its shape and position more stably when subjected to shear force, and will not be deformed or damaged.

[0033] See Figure 1 , Figure 2 and Figure 3 One side of the fixing clamp 5 has a hollow groove 11 for welding. The hollow groove 11 is set in an arc shape. Since the arc shape has good mechanical properties and stability, making the hollow groove 11 into an arc shape can enhance the overall strength and stability of the fixing clamp 5 to a certain extent. This allows the fixing clamp 5 to maintain its shape and position more stably when subjected to external forces, without deformation or damage, thereby ensuring the stability and reliability of the entire assembly node.

[0034] The implementation principle of this utility model is as follows: First, align the upper steel column 1 and the lower steel column 2. Then, insert the first pressing block 91 of the fixing clamp 5 into the first pressure groove 71 of the upper connecting steel plate 3. Through the cooperation between the triangular first pressure groove 71 and the first pressing block 91, it is ensured that even if the position of the first pressure groove 71 of the upper connecting steel plate 3 deviates from that of the inner hole 8, the inner hole 8 and the outer hole 10 can still be aligned. And through the reliable fixing of the wedge plate 6, the upper steel column 1 and the lower steel column 2 are temporarily fixed. After all the components are installed in place, the upper steel column 1 and the lower steel column 2 are welded together. At this time, an extra gap is left at the position of the empty groove 11 to facilitate welding. After welding is completed, the connecting steel plate, the fixing clamp 5 and the wedge plate 6 are removed to complete the entire installation process.

[0035] Example 2:

[0036] See Figure 4 The pressure-bearing structure 7 includes a second pressure-bearing groove 72, which is rectangular in shape. The bottom of the second pressure-bearing groove 72 is provided with an arc 73. During the process of pressing the clamping structure 9 into the second pressure-bearing groove 72, the arc 73 can gradually absorb and disperse the pressure, avoiding local deformation or damage caused by pressure concentration. This not only improves the pressure resistance of the assembly node, but also extends its service life.

[0037] See Figure 4The clamping structure 9 includes a second clamping block 92, which is cylindrical in shape. During installation, due to various factors, there may be slight deviations or positional changes between the clamping structure 9 and the second pressure groove 72. When the cylindrical second clamping block 92 is pressed into the second pressure groove 72, it can automatically adjust its position to form a tight fit with it, thereby achieving the effect of automatic guidance and self-positioning.

[0038] The implementation principle of this utility model is as follows: First, align the upper steel column 1 and the lower steel column 2. Then, insert the second pressing block 92 of the fixing clamp 5 into the second pressure groove 72 of the upper connecting steel plate 3. Through the cooperation between the cylindrical first pressing block 91 and the arc at the bottom of the first pressure groove 71, the fixing clamp 5 can rotate, ensuring that even if there is a deviation between the position of the second pressure groove 72 of the upper connecting steel plate 3 and the inner hole 8, the inner hole 8 and the outer hole 10 can still be aligned. And through the reliable fixing of the wedge plate 6, the upper steel column 1 and the lower steel column 2 are temporarily fixed. After all the components are installed in place, the upper steel column 1 and the lower steel column 2 are welded together. At this time, an extra gap is left at the position of the empty groove 11 to facilitate welding. After welding, the connecting steel plate, the fixing clamp 5 and the wedge plate 6 are removed to complete the entire installation process.
