Description
Technical Field
[0001] This utility model relates to the field of steel structure column splicing construction technology, and in particular to a vertical steel structure column splicing structure. Background Technology
[0002] In steel structure construction, the splicing of vertical steel columns is one of the core construction steps, especially the vertical splicing of round steel columns. It is necessary to ensure the verticality and coaxiality of the spliced columns, while also achieving temporary stabilization to meet the needs of subsequent welding operations. Existing technical problems with round steel column splicing methods often involve direct butt welding followed by fixing, or temporarily fixing the columns by welding connecting plates to the lower and upper columns and then connecting them with bolts. However, direct butt welding makes it difficult to quickly and accurately align the round steel columns, easily leading to misalignment and affecting the structural load-bearing performance. Furthermore, the method of welding connecting plates to the lower and upper columns and then connecting them with bolts is prone to displacement during the welding process. The bolt connection process requires a large number of bolts, making installation cumbersome, and the connecting plates need to be cut after completion, which is difficult to disassemble and can easily damage the steel columns, increasing construction risks and costs. Utility Model Content
[0003] The purpose of this utility model is to provide a vertical steel column splicing structure. The technical problem to be solved is that the steel column splicing process requires welding connecting plates separately, using a large number of bolts, which is cumbersome to install. Moreover, after completion, the connecting plates need to be cut, which is not easy to disassemble and can easily damage the steel column, increasing construction risks and costs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vertical steel column splicing structure includes a lower column and an upper column vertically spliced together, and a splicing component disposed between the lower column and the upper column. The lower column has a top partition plate at its top, with a limiting protrusion on its top surface. The upper column has an upper column partition plate at its bottom, with a limiting groove on its bottom surface. The limiting protrusion and the limiting groove are vertically aligned and of compatible specifications, and the limiting protrusion engages with the limiting groove. The splicing component includes an auxiliary limiting member at the top of the lower column and a limiting member at the bottom of the lower column. The fixing clamps on the outer periphery of the positioning component include auxiliary limiting components such as column clamps and multiple sets of column clamping plates. The column clamps are clamped at the top of the lower column, and the multiple sets of column clamping plates are distributed around the column clamps. Each column clamping plate includes a connecting ear plate and a clamping plate. The connecting ear plate is integrally formed on the side of the column clamp. One end of the clamping plate and the connecting ear plate are hinged by a pin. Both sides of the clamping plate and the connecting ear plate are flush with both sides of the column clamp. The inner side of the clamping plate is attached to the outer periphery of the upper column. The fixing clamps have the same structure as the column clamps and are clamped on the outer periphery of the clamping plates.
[0005] Furthermore, the column clamp includes a first clamp body and a second clamp body, both of which are semi-circular ring structures. The ring openings of the first and second clamp bodies are arranged opposite each other. The two ends of the first and second clamp bodies are respectively a hinged end and a fixed end. The hinged ends of the first and second clamp bodies are hinged together by a pin. The fixed end of the first clamp body is provided with a screw rod, the end of which is hinged to the first clamp body. A fixing nut is provided on the screw rod. The fixed end of the second clamp body is provided with a limiting plate that works with the screw rod. The limiting plate is perpendicular to the fixed end of the second clamp body. A concave limiting opening is fixed on the limiting plate. The screw rod is located inside the concave limiting opening of the limiting plate. The screw rod is fixed to the limiting plate by a fixing nut.
[0006] Furthermore, the outer periphery of the top partition is fixed to the inner wall of the lower column, and the surface of the top partition facing the top of the lower column is flush with the top of the lower column.
[0007] Furthermore, the width of the concave limiting opening of the limiting plate is greater than the diameter of the screw and less than the outer circumference width of the fixing nut.
[0008] Furthermore, the top of the limiting plate on the side facing away from the second locking body ring is provided with a locking block, the distance between the locking block and the second locking body is adapted to the specifications of the fixing nut, and the locking block is locked on the top of the fixing nut.
[0009] Furthermore, both the connecting ear plate and the clamping plate are strip plates, the length of the connecting ear plate is less than the length of the clamping plate, and the width of both the connecting ear plate and the clamping plate is the same as the thickness of the first card body.
[0010] Furthermore, the back side of the clamp is provided with a receiving groove for accommodating the fixing clamp.
[0011] Furthermore, the depth of the limiting groove is the same as the protrusion height of the limiting protrusion.
[0012] Compared with the prior art, this utility model has the following features and beneficial effects: This invention achieves rapid coaxiality and verticality calibration when splicing the lower and upper columns through precise matching of the limiting protrusions and limiting grooves. This avoids the misalignment problems that easily occur with traditional direct welding, ensuring uniform stress on the spliced structure and improving the overall project quality. By setting up splicing components, there is no need to weld additional connecting plates or use a large number of bolts. With the combination of openable column clamps, fixed clamps, and adjustable column clamp plates, temporary fixation can be quickly completed, greatly simplifying the installation process, reducing construction time, and improving work efficiency. The auxiliary limiting components and fixed clamps are all detachable structures. After completion, there is no need for cutting operations; they can be directly unlocked and removed, completely solving the problem of steel column damage caused by cutting traditional connecting plates. This reduces later repair costs and construction risks. The splicing components can be reused in multiple splicing scenarios after disassembly without additional consumables, while also reducing the technical problems of costs caused by steel column damage, repair, and material waste.

[0016] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model.

In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application.

[0017] This utility model discloses a vertical steel column splicing structure, such as Figure 1As shown, the system includes a lower column 1 and an upper column 2 vertically spliced together, and a splicing component located between the splicing ends of the lower column 1 and the upper column 2. Both the lower column 1 and the upper column 2 are round steel columns. The bottom end of the upper column 2 is vertically spliced to the top end of the lower column 1. The top end of the lower column 1 is provided with a top partition plate, the outer periphery of which is fixed to the inner wall of the lower column 1. The surface of the top partition plate facing the top end of the lower column 1 is flush with the top end of the lower column 1. A limiting protrusion is provided on the top surface of the top partition plate. The bottom end of the upper column 2 is provided with an upper column partition plate. A limiting groove is provided on the surface of the upper column partition plate facing the bottom end of the upper column 2. The limiting groove is adapted to the limiting protrusion, and the depth of the limiting groove is the same as the height of the limiting protrusion. When the bottom end of the upper column 2 is vertically spliced to the top end of the lower column 1... The limiting protrusion fits perfectly into the limiting groove, thus assisting the bottom of the upper column 2 and the top of the lower column 1 in completing the initial splicing. The splicing components include an auxiliary limiting component located at the top of the lower column 1 and a fixing clamp 4 located on the outer periphery of the auxiliary limiting component. The auxiliary limiting component is detachably fixed to the outer periphery of the top of the lower column 1. The auxiliary limiting component includes a column clamp 3 and multiple sets of column clamping plates, which are distributed around the column clamp 3. The column clamp 3 includes a first clamp body and a second clamp body, both of which are semi-circular ring structures. The ring openings of the first and second clamp bodies are arranged opposite each other. The two ends of the first and second clamp bodies are respectively hinged ends and fixed ends. The hinged ends of the first and second clamp bodies are hinged by a pin. The fixed end of the first clamp is provided with a screw 7, the end of which is hinged to the first clamp body. A fixing nut 8 is provided on the screw 7. The fixed end of the second clamp body is provided with a limiting plate 9 that works with the screw 7. The limiting plate 9 is perpendicular to the fixed end of the second clamp body. A concave limiting opening is fixed on the limiting plate 9. The width of the concave limiting opening of the limiting plate 9 is greater than the diameter of the screw 7 and less than the outer circumference width of the fixing nut 8. In use, the column clamp 3 is placed on the top of the lower column 1. By rotating the screw 7, the screw 7 can be rotated into the concave limiting opening of the limiting plate 9. Then, the screw 7 is fixed to the limiting plate 9 by tightening the fixing nut 8, thereby fixing the fixed ends of the first and second clamp bodies. In addition, the column clamp 3 is fixed to the top of the lower column 1, and the limiting plate 9 faces away from the second clamp body. A locking block 10 is provided on the top of one side of the ring. The distance between the locking block 10 and the second clamping body is adapted to the specifications of the fixing nut 8. After the fixing nut 8 is tightened, the locking block 10 is locked on the top of the fixing nut 8, thereby preventing the screw 7 from falling off. The column clamping plate includes a connecting ear plate 5 provided on the column clamping clamp 3 and a clamping plate 6 provided on the connecting ear plate 5. The connecting ear plate 5 and the column clamping clamp 3 are integrally formed. Both the connecting ear plate 5 and the clamping plate 6 are strip plates. The length of the connecting ear plate 5 is less than the length of the clamping plate 6. The width of both the connecting ear plate 5 and the clamping plate 6 is the same as the thickness of the first clamping body. The connecting ear plate 5 is provided on the side of the column clamping clamp 3. Through holes are opened on the connecting ear plate 5 and the clamping plate 6. The clamping plate 6 and the connecting ear plate 5 are hinged by a pin. Both sides of the clamping plate 6 and the connecting ear plate 5 are flush with both sides of the column clamping clamp 3.After the lower column 1 and the upper column 2 are spliced together, the inner side of the clamping plate 6 is attached to the outer periphery of the upper column 2. The fixing clamp 4 has the same structure as the column clamp 3. The back side of the clamping plate 6 has a receiving groove for accommodating the fixing clamp 4. The fixing clamp 4 is clamped to the outer periphery of the clamping plate 6. The clamping plate 6 is attached and fixed to the upper column 2 by the fixing clamp 4, thereby temporarily splicing and fixing the lower column 1 and the upper column 2, facilitating subsequent welding operations between the lower column 1 and the upper column 2.
[0018] During installation, first fix the lower column 1 in place. After opening and closing the first and second clamps of the column clamp 3, place them on the top of the lower column 1. Rotate the screw 7 to insert it into the concave limiting port of the limiting plate 9, and tighten the fixing nut 8 to fix the column clamp 3 to the top of the lower column 1. At this time, the clamp block 10 is locked on the top of the fixing nut 8. Adjust the angle of the clamping plates 6 of each set of column clamping plates to make them open to facilitate the connection of the upper column 2. Lift the upper column 2 so that the limiting groove of the upper column partition is aligned with the upper column partition. The limiting protrusion of the lower column 1 is slowly lowered until it is fully embedded in the limiting groove, completing the initial centering. The clamps 6 of each set of column clamping plates are rotated one by one so that the inner side of the clamps 6 is in contact with the outer circumference of the upper column 2. The fixing clamps 4 are put on the outer circumference of each set of clamps 6 and inserted into the receiving groove. After locking, the clamps 6 are pressed and fixed to the upper column 2. The verticality and coaxiality are checked. After confirming that there are no errors, the welding operation is carried out. After the welding is completed, the fixing clamps 4 and auxiliary limiting parts are removed to complete the splicing construction.
