Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a modular steel structure column base that can be quickly assembled and disassembled. Background Technology

[0002] Steel column bases are key components connecting steel columns to the foundation in buildings or structural engineering. They not only play a vital role in transferring the loads of the superstructure to the foundation but also ensure the stability and safety of the structure. Column base designs typically include three types: hinged, rigid, and semi-rigid connections, to accommodate different structural requirements and mechanical performance specifications.

[0003] Traditional non-modular column base installations typically require on-site welding or complex bolt connections. These operations are not only time-consuming but also demand a high level of skill from the construction environment and workers, and are prone to safety hazards or quality instability due to improper operation. Furthermore, due to the strong overall structure, it is difficult to replace or upgrade individual parts, often leading to the need for reconstruction or abandonment of the entire structure, resulting in a waste of materials and resources.

[0004] Therefore, it is necessary to design a modular steel structure column base that can be quickly assembled and disassembled to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional column base installation, which relies heavily on on-site welding or complex bolts, is time-consuming and labor-intensive, has high environmental and technical requirements, is prone to safety and quality problems, has strong overall structural integrity, is difficult to replace locally, and often requires reconstruction or abandonment, resulting in waste, this utility model provides a modular steel structure column base that can be quickly assembled and disassembled.

[0006] A modular steel structure column base that can be quickly assembled and disassembled includes a base plate, a column, a two-way screw, a snap-fit ​​connector, a guide rod, a connecting rod, a snap-fit ​​plate, a movable plate, and a pre-embedded plate. The column is fixedly connected to the top of the base plate, and a square groove is opened inside the column. The two-way screw is rotatably connected to the top of the base plate. Two snap-fit ​​connectors are fixedly connected to both ends of the two-way screw, and a hexagonal groove is opened on one side of each snap-fit ​​connector. The guide rod is fixedly connected to the top of the base plate and is symmetrically distributed with the two-way screw. The two-way screw has symmetrically opened threaded grooves, and the two connecting rods are threadedly connected to the corresponding threaded grooves of the two-way screw. The two connecting rods slide on the guide rod. The two snap-fit ​​plates are rotatably connected to the corresponding connecting rods. The two movable plates are slidably connected to both sides of the base plate, and a snap-fit ​​groove is opened on one side of each movable plate. The two snap-fit ​​plates are snapped into the corresponding snap-fit ​​grooves. The pre-embedded plate is fixedly connected between the bottom surfaces of the two movable plates.

[0007] To further explain, it also includes sleeves, extrusion plates, and springs. The four sleeves are divided into two groups, with two sleeves in each group. Each group of sleeves is slidably connected to both sides of the base plate. The two sleeves in each group are symmetrically distributed. The extrusion plate is fixedly connected between the bottoms of the four sleeves. The four springs are connected between the base plate and the extrusion plate, and the four springs are wound inside the corresponding sleeves.

[0008] To further explain, it also includes a guide cylinder, rollers and guide belts. The guide cylinder is fixedly connected to the top surface of the column. Through slots are opened on both sides of the guide cylinder. The four rollers are divided into two groups, with two rollers in each group. The two rollers in each group are rotatably connected to the two sides of the corresponding through slots, and the two guide belts are wrapped between the two rollers in each group.

[0009] To further explain, it also includes a level, with two levels fixedly connected to the top of the corresponding movable plate.

[0010] To further clarify, both levels are bubble levels.

[0011] To further explain, the guide cylinder has a vertical groove that communicates with the square groove.

[0012] The beneficial effects of this utility model are as follows: By combining the embedded plate with the concrete, the stability and levelness of the structure are ensured. Precise detection using a bubble level guarantees installation accuracy. The bidirectional screw drive allows the connecting rods to move closer or further apart, facilitating convenient installation and disassembly of the snap-fit ​​plate, simplifying the construction process, and improving work efficiency. In particular, during steel structure installation, the guide belt and rotating roller reduce friction, not only accelerating the insertion speed but also reducing the risk of damage to the material surface. After installation, a stable triangular structure is formed, enhancing the overall structural stability and load-bearing capacity. Furthermore, the device supports quick disassembly, facilitating maintenance, replacement, or adjustment, greatly improving flexibility and economy of use, while reducing resource waste caused by structural adjustments.

Detailed Implementation

[0018] Example: A modular steel structure column base that can be quickly assembled and disassembled, such as... Figures 1-4 As shown, the structure includes a base plate 1, a column 2, a double-ended screw 3, a clamping joint 4, a guide rod 5, a connecting rod 6, a clamping plate 7, a movable plate 8, an embedded plate 10, and a level 9. The column 2 is welded to the top of the base plate 1. The column 2 has a square groove inside suitable for the size of the steel structure. The double-ended screw 3 is rotatably connected to the right side of the top surface of the base plate 1. Two clamping joints 4 are welded to the front and rear ends of the double-ended screw 3. Hexagonal grooves are formed on the sides of the two clamping joints 4 that are furthest from each other. The guide rod 5 is welded to the left side of the top surface of the base plate 1 and is symmetrically distributed with the double-ended screw 3. Threaded grooves are symmetrically opened on the front and rear of the screw 3, so that the two connecting rods 6 are threadedly connected to the corresponding threaded grooves of the bidirectional screw 3. Both connecting rods 6 slide on the guide rod 5. Both snap-fit ​​plates 7 are rotatably connected to the corresponding connecting rods 6. Both moving plates 8 are slidably connected to the front and rear sides of the base plate 1. Snap-fit ​​grooves are opened on the sides of the two moving plates 8 that are close to each other, and both snap-fit ​​plates 7 snap into the corresponding snap-fit ​​grooves. The embedded plate 10 is welded between the bottom surfaces of the two moving plates 8. Both levels 9 are installed on the top of the corresponding moving plates 8 by screws. Both levels 9 are bubble levels.

[0019] like Figure 1 and Figure 3 As shown, it also includes sleeves 11, extrusion plates 12 and springs 13. The four sleeves 11 are divided into two groups, with two in each group. Each group of sleeves 11 is slidably connected to the left and right sides of the base plate 1. The two sleeves 11 in each group are symmetrically distributed front and back. The extrusion plates 12 are welded between the bottoms of the four sleeves 11. The four springs 13 are connected between the base plate 1 and the extrusion plates 12. The four springs 13 are wound inside the corresponding sleeves 11.

[0020] like Figure 1 and Figure 4 As shown, it also includes a guide cylinder 14, rollers 15 and guide belts 16. The guide cylinder 14 is fixedly connected to the top surface of the column 2. Through slots are opened on both the left and right sides of the guide cylinder 14. The four rollers 15 are divided into two groups, with two rollers in each group. The two rollers 15 in each group are rotatably connected to the upper and lower sides of the corresponding through slots. The two guide belts 16 are wrapped between the two rollers 15 in each group. Vertical slots are opened on the guide cylinder 14, and the vertical slots are connected to the square slots.

[0021] When the device is needed, first dig a groove at the installation location, place the embedded plate 10 in the groove, and use a level 9 to check whether the embedded plate 10 is placed on the same horizontal line. Since the level 9 is a bubble level 9, it contains liquid and an air bubble. By observing the position of the air bubble in the marked area, you can determine whether it is horizontal or vertical. After the embedded plate 10 is placed horizontally, pour concrete to the top of the embedded plate 10. Then insert the base plate 1 into the moving plate 8, and use a hexagonal tool to insert it into the hexagonal groove of the clamping connector 4. Then, use the hexagonal tool to rotate the clamping connector 4 to drive the double-ended screw 3, so that the two connecting rods 6 move closer to each other. During the movement, the clamping plate 7 is rotated and clamped into the clamping groove. Then, continue to rotate the double-ended screw 3, and the clamping plate 7 is squeezed. Since the embedded plate 10 is fixed by the concrete, the base plate 1 moves downward along the moving plate 8, and the compression plate 12 is squeezed and contacts the concrete. When the spring 13 is compressed and deformed, the moving plate 8, the base plate 1, and the snap-fit ​​plate 7 form a triangular structure with stability. The base plate 1 cannot be pulled out from the moving plate 8, thus completing the installation of the entire device. Then, the steel structure is inserted into the vertical groove, and its side will contact the guide belt 16. Under the rotation of the two rollers 15, the friction between the steel structure and the inner wall is reduced, allowing the steel structure to be quickly inserted into the vertical groove and then into the square groove, thus completing the installation of the steel structure. When it is necessary to disassemble the steel structure, the steel structure is pulled out of the square groove and the vertical groove. Then, a hexagonal tool is inserted into the hexagonal groove, which drives the bidirectional screw 3 to reverse. The two connecting rods 6 move to the side away from each other. At the same time, the base plate 1 moves upward and resets under the action of the spring 13. When the snap-fit ​​plate 7 moves to a certain distance, it reverses and rotates the snap-fit ​​plate 7 away from the snap-fit ​​groove. At this time, the base plate 1 can be removed from the moving plate 8, thus completing the disassembly of the entire device.
