Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a lattice-type composite steel pipe column. Background Technology

[0002] In the field of building construction, lattice-type composite steel pipe columns are widely used as an important supporting structure. Temporary fixing is a crucial step in their construction, directly affecting the safety and quality of subsequent construction.

[0003] Traditional temporary fixing of lattice-type composite steel pipe columns typically involves manually hammering wedges. This method has several drawbacks. For example, hammering the wedges requires significant physical exertion, resulting in extremely high labor intensity. Furthermore, relying entirely on manual hammering makes it difficult to precisely control the degree of fixation, easily leading to insecure fixing. This poses a serious threat to the stability of the lattice-type steel pipe columns and could potentially cause safety accidents. In addition, this traditional method is cumbersome, inefficient, and severely slows down construction progress, increasing construction costs.

[0004] In summary, traditional temporary fixing technology for lattice-type composite steel pipe columns can no longer meet the demands of efficient, safe, and high-quality construction in modern building engineering, necessitating a new temporary fixing technology to address these issues. Therefore, we propose a lattice-type composite steel pipe column. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a lattice-type composite steel pipe column, which solves the above-mentioned problems.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a lattice-type composite steel pipe column, including a lattice-type steel pipe pile body, a fixing ring fixedly connected to each of the four column feet at the bottom of the lattice-type steel pipe pile body, a fixing groove provided on the fixing ring, a connecting ring movably engaged inside the fixing groove, four U-shaped connecting blocks fixedly connected at equal intervals on the outer wall surface of the connecting ring, a rack capable of moving up and down provided inside each of the four U-shaped connecting blocks, a washer fixedly connected to the bottom of the rack, and a linkage mechanism for driving the rack to move provided on each of the four U-shaped connecting blocks.

[0007] Preferably, the linkage mechanism includes a turntable, a U-shaped linkage block, a linkage column, a gear, and slots. A movable U-shaped linkage block is provided on the side of the U-shaped connecting block away from the connecting ring. A linkage column is movably connected to the U-shaped linkage block via a bearing. A gear is provided inside the U-shaped connecting block, and the gear meshes with a rack. The gear is fixedly connected to the linkage column. A turntable is fixedly connected to the end of the linkage column away from the U-shaped connecting block. A plurality of slots are equidistantly provided on the outer wall of the turntable, and the number of slots is not less than four.

[0008] Preferably, the U-shaped connecting block has connecting grooves on the side wall away from the connecting ring at both ends. The two ends of the U-shaped linkage block are movably engaged with the inside of the two connecting grooves on the U-shaped connecting block. A tension spring is fixedly connected inside the two connecting grooves. The free end of the tension spring is fixedly connected to the side wall adjacent to the two ends of the U-shaped linkage block.

[0009] Preferably, a support column is fixedly connected to the inner wall of the U-shaped connecting block, and a slot is formed on the side wall of the linkage column near the connecting ring at the position corresponding to the support column, and the end of the support column away from the connecting ring extends into the inside of the slot.

[0010] Preferably, the inner wall of the U-shaped connecting block is provided with a T-shaped groove corresponding to the position of the rack, and the outer wall of the rack is fixedly connected with a T-shaped slider corresponding to the position of the T-shaped groove, and the T-shaped slider is movably engaged inside the T-shaped groove.

[0011] Preferably, the connecting ring is a circular ring structure, which consists of two symmetrically arranged semi-circular ring blocks. The ends of the two semi-circular ring blocks on one side of the connecting ring are hinged together by a hinge, and the ends of the two semi-circular ring blocks on the other side of the connecting ring are fixedly connected together by bolts and nuts.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a linkage mechanism, at least four slots are provided on the outer wall of the turntable during use, allowing workers to easily rotate the turntable using the lever principle to drive the rack movement. Compared to the traditional method of directly hammering the wedges by hand, workers do not need to expend a lot of physical strength to overcome significant resistance. They can precisely control the degree of pressure exerted by the rack on the wedges by simply turning the lever inserted into the slot, significantly reducing labor intensity and avoiding potential damage to the equipment due to improper force. This improves the safety and convenience of operation, effectively shortens the temporary fixing time of a single steel pipe pile, and thus accelerates the overall construction progress.

[0013] 2. By using a combination structure of connecting groove, tension spring, and U-shaped linkage block, the initial position of the rack is quickly and conveniently adjusted. In actual operation, workers can easily pull the U-shaped linkage block to separate the gear from the rack, allowing the rack to quickly reach the initial contact position with the wedge under gravity. Then, the U-shaped linkage block is released to re-engage the gear and rack, and the degree of rack compression against the wedge is finely adjusted using a turntable. This process greatly reduces the tedious manual adjustment of the rack height, saving time and effort, further improving the efficiency of temporary fixing operations, and making the entire construction process smoother and more efficient.

[0014] 3. By employing a connecting ring design consisting of two symmetrical semi-circular blocks connected by hinges and bolts / nuts, easy installation and disassembly are achieved. During transportation, storage, and routine maintenance, workers can easily remove the connecting ring from the lattice steel pipe pile body for separate storage and management, reducing the overall space occupied by the equipment and lowering transportation costs and storage difficulties. Simultaneously, when installation is required on-site, the connecting ring can be assembled quickly and accurately, improving the equipment's flexibility and operability, extending its service life, and reducing its overall operating costs.

[0015] 4. By setting a matching structure between the support column and the slot on the linkage column on the inner wall of the U-shaped connecting block, the overall rigidity of the linkage mechanism is enhanced. During long-term and frequent use, this rigid structure effectively resists various external forces, preventing deviations in the meshing of the gears and rack due to deformation under stress. This ensures the accuracy and stability of rack movement, guarantees the reliable operation of the temporary fixing device, reduces the frequency of maintenance and replacement due to equipment failure, improves the reliability and durability of the equipment, and provides strong support for the smooth progress of construction.

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0019] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 5 The present invention will be further described below.

[0020] A lattice-type composite steel pipe column includes a lattice-type steel pipe pile body 1. Each of the four column feet at the bottom of the lattice-type steel pipe pile body 1 is fixedly connected to a fixing ring 2. The fixing ring 2 is a cylindrical tube with a fixing groove 3. A connecting ring 4 is movably engaged inside the fixing groove 3. Four U-shaped connecting blocks 5 are equidistantly fixedly connected to the outer wall of the connecting ring 4. Each of the four U-shaped connecting blocks 5 has a vertically movable rack 6 inside. A shim 18 is fixedly connected to the bottom of the rack 6. Each of the four U-shaped connecting blocks 5 is equipped with a linkage mechanism for driving the rack 6 to move.

[0021] When in use, after the workers lift the lattice steel pipe pile body 1 with a crane and place it in the designated position, they place the wedges at the four column bases in sequence, ensuring that they correspond vertically with the four U-shaped connecting blocks 5 on the column bases. Then, the workers can drive the rack 6 downward through the drive mechanism. The rack 6, together with the shim 18, can press down on the wedges to fix them, thereby achieving the effect of temporarily fixing the lattice steel pipe pile body 1.

[0022] The linkage mechanism includes a turntable 7, a U-shaped linkage block 10, a linkage column 13, a gear 14, and slots 15. A movable U-shaped linkage block 10 is provided on the side of the U-shaped connecting block 5 away from the connecting ring 4. The linkage column 13 is movably connected to the U-shaped linkage block 10 through a bearing. A gear 14 is provided inside the U-shaped connecting block 5. The gear 14 meshes with the rack 6 and is fixedly connected to the linkage column 13. A turntable 7 is fixedly connected to the end of the linkage column 13 away from the U-shaped connecting block 5. When the turntable 7 rotates, it will drive the gear 14 to rotate. By changing the rotation direction of the gear 14, the rack 6 can be controlled to move up or down inside the U-shaped connecting block 5. When the rack 6 moves down, it can cooperate with the shim 18 to press and fix the wedge. Several slots 15 are equally spaced on the outer wall of the turntable 7, and the number of slots 15 is not less than four.

[0023] When in use, workers can easily rotate the turntable 7 by inserting a suitable tube into the slot 15 and changing the lever arm through the lever principle. The turntable 7 drives the gear 14 to rotate, which controls the rack 6 to move downward inside the U-shaped connecting block 5, thereby squeezing and fixing the wedge. Compared with the traditional method of workers fixing the wedge by hammering it, this device can not only greatly reduce the labor intensity of workers, but also greatly reduce safety hazards.

[0024] By setting no fewer than four slots 15, it can be ensured that there is always a slot 15 in which workers can easily insert pipes to complete the rotation of the turntable 7, thereby improving the convenience of the equipment.

[0025] Connecting grooves 11 are provided on the side wall away from the connecting ring 4 at both ends of the U-shaped connecting block 5. Both ends of the U-shaped linkage block 10 are movably engaged inside the two connecting grooves 11 on the U-shaped connecting block 5. Tension springs 12 are fixedly connected inside the two connecting grooves 11. The free ends of the tension springs 12 are fixedly connected to the side wall adjacent to both ends of the U-shaped linkage block 10. When in use, the operator can pull the U-shaped linkage block 10 outward. At this time, the tension springs 12 deform and the U-shaped linkage block 10 moves away from the U-shaped connecting block 5. At this time, the gear 14 will move synchronously away from the U-shaped connecting block 5 under the influence of the U-shaped linkage block 10, which will cause the gear 14 to separate from the rack 6 and no longer maintain the meshing state. When the operator stops pulling the U-shaped linkage block 10, the U-shaped linkage block 10 will reset under the action of the tension springs 12, and the gear 14 will mesh with the rack 6 again.

[0026] When in use, the operator can pull the U-shaped linkage block 10 outward to separate the gear 14 from the rack 6. At this time, the rack 6 will slide downward inside the U-shaped connecting block 5 under its own weight until the washer 18 on the rack 6 contacts the wedge. Then, the operator releases the U-shaped linkage block 10 to make the gear 14 and rack 6 mesh again. Subsequently, the wedge can be pressed and fixed by rotating the turntable 7. Therefore, by pulling the U-shaped linkage block 10, the position of the rack 6 can be quickly adjusted, thereby reducing the time for the operator to adjust the height of the rack 6 and improving work efficiency.

[0027] The inner wall of the U-shaped connecting block 5 is fixedly connected with a support column 16. The side wall of the linkage column 13 near the connecting ring 4 is provided with a slot 17 corresponding to the position of the support column 16. The end of the support column 16 away from the connecting ring 4 extends into the inside of the slot 17.

[0028] When in use, since one end of the support column 16 extends into the inside of the slot 17 on the linkage column 13, the rigidity of the mechanism itself can be greatly improved, thereby ensuring its service life.

[0029] The inner wall of the U-shaped connecting block 5 has a T-shaped groove 8 corresponding to the position of the rack 6. The outer wall of the rack 6 is fixedly connected to a T-shaped slider 9 corresponding to the position of the T-shaped groove 8. The T-shaped slider 9 is movably engaged inside the T-shaped groove 8. The rack 6 is movably engaged inside the U-shaped connecting block 5 through the cooperation of the T-shaped groove 8 and the T-shaped slider 9.

[0030] The connecting ring 4 has a circular ring structure. The connecting ring 4 is composed of two symmetrically arranged semi-circular ring blocks. The two semi-circular ring blocks on one side of each other are hinged together by a hinge. The other two semi-circular ring blocks on the other side of each other are fixedly connected together by bolts and nuts.

[0031] Since the connecting ring 4 is composed of two symmetrically arranged semicircular ring blocks, and the two semicircular ring blocks on the connecting ring 4 are fixedly connected by bolts and nuts, the connecting ring 4 can be easily installed and disassembled. Therefore, when it is normally placed, the connecting ring 4 can be removed from the lattice steel pipe pile body 1 and stored separately. When it is needed, it can be installed, thereby improving the flexibility and service life of the equipment.

[0032] Working principle: When in use, after the workers lift the lattice steel pipe pile body 1 with a crane and place it in the designated position, they place the wedges at the four column bases in sequence, ensuring that they correspond vertically with the four U-shaped connecting blocks 5 on the column bases. Then, the workers can drive the rack 6 downward through the drive mechanism. The rack 6, together with the shim 18, can press down on the wedges to fix them, thereby achieving the effect of temporarily fixing the lattice steel pipe pile body 1.

[0033] When in use, workers can easily rotate the turntable 7 by inserting a suitable tube into the slot 15 and changing the lever arm through the lever principle. The turntable 7 drives the gear 14 to rotate, which controls the rack 6 to move downward inside the U-shaped connecting block 5, thereby squeezing and fixing the wedge. Compared with the traditional method of workers fixing the wedge by hammering it, this device can not only greatly reduce the labor intensity of workers, but also greatly reduce safety hazards.

[0034] When in use, the operator can pull the U-shaped linkage block 10 outward to separate the gear 14 from the rack 6. At this time, the rack 6 will slide downward inside the U-shaped connecting block 5 under its own weight until the washer 18 on the rack 6 contacts the wedge. Then, the operator releases the U-shaped linkage block 10 to make the gear 14 and rack 6 mesh again. Subsequently, the wedge can be pressed and fixed by rotating the turntable 7. Therefore, by pulling the U-shaped linkage block 10, the position of the rack 6 can be quickly adjusted, thereby reducing the time for the operator to adjust the height of the rack 6 and improving work efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
