Description

Technical Field

[0001] This utility model relates to the field of steel column installation technology, specifically to a rapid positioning and installation device for steel columns. Background Technology

[0002] As a key specialized equipment in the field of steel structure building construction, the core of the steel column positioning and installation device lies in achieving efficient and accurate positioning, dynamic leveling and correction, and reliable fixing of steel columns through mechanical transmission structure optimization or intelligent control technology integration. This significantly improves construction efficiency and reduces labor intensity compared to traditional manual installation methods, thus meeting the requirements for efficient and accurate installation of steel columns.

[0003] However, the devices currently used in engineering generally have the following problems: First, they have limited adaptability to specific application scenarios. Most devices are only designed for steel column specifications, installation conditions, and connection methods preset for specific projects. When faced with ultra-wide cross-section steel columns, variable cross-section components, or multi-dimensional inclined installation requirements, multiple sets of special devices need to be configured, resulting in high equipment idle rates and a surge in warehousing and transportation costs. Second, the structural design is too rigid. The core positioning units (such as guide rails and support frames) mostly adopt a fixed spacing layout, which can only match a single specific size steel column. This cannot meet the need for flexible layout adjustments during actual installation. In actual construction, due to dimensional fluctuations caused by steel column processing errors or design changes, problems such as positioning jamming and unstable support often occur. This not only affects installation efficiency but also easily leads to positioning deviations exceeding specifications, forcing rework and rectification. Utility Model Content

[0004] The purpose of this invention is to provide a rapid positioning and installation device for steel columns to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a quick positioning and installation device for steel columns, comprising: an upper device, the upper device including a fixing plate, a first slot being formed in the center of the fixing plate, a plurality of second slots being symmetrically arranged on the outer side of the first slot, and each second slot communicating with the first slot, a third slot being formed on one side of the inner wall of each second slot, the third slot communicating with the second slot, a sliding plate being slidably installed on the inner wall of the third slot, a support column being fixedly connected to one side of the sliding plate, a locking mechanism being fixedly connected to the upper end of the support column, and a steel column body being slidably installed on the side of the plurality of locking mechanisms that are close to each other.

[0006] In a preferred embodiment, the locking mechanism includes a limiting block fixedly disposed on the upper end of the support column, a fixing block disposed on the outer side of the limiting block, a first threaded hole being formed through the fixing block, and a second threaded hole corresponding to the first threaded hole being formed through the limiting block. The first threaded hole and the second threaded hole are interconnected. A first threaded rod is threadedly installed on the inner wall of the first threaded hole. The inner end of the first threaded rod passes through the first threaded hole and extends to the inner side of the second threaded hole. A clamping block is fixedly connected to the inner end of the first threaded rod.

[0007] In a preferred embodiment, the upper end of the fixed plate is provided with a plurality of third screw holes, which correspond to each other with the third slot holes. The upper end of the sliding plate is provided with a fourth screw hole, which is interconnected with the third screw holes. A bolt is threaded on the inner wall of the third screw hole, and one end of the bolt extends to the inner wall of the fourth screw hole.

[0008] In a preferred embodiment, a fifth screw hole is provided through the four corners of the upper end of the fixing plate, and a second threaded rod is installed in the fifth screw hole. The lower end of the second threaded rod is connected to the lower device, and the lower device and the upper device are symmetrically arranged with respect to the center point of the second threaded rod.

[0009] In a preferred embodiment, the side of the plurality of clamping blocks that is close to each other is provided as an arc surface, and the arc surface is provided with anti-slip grooves.

[0010] In a preferred embodiment, the inner wall of the third slot is in contact with the side wall of the sliding plate, and the inner wall of the second slot is in contact with the side wall of the support column.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model addresses the single steel column scenario, allowing for a separate upper device. A fixing plate is secured using a second threaded rod and a fifth threaded hole, fulfilling the need for installing a single steel column on the ground. For the double steel column scenario, the upper and lower devices are combined. The lower device is fixed to the upper end of the first steel column, while the upper device is used to install the second steel column, achieving the installation requirement across steel columns without the need to purchase multiple sets of equipment.

[0012] 2. This utility model solves this problem by using the core structure of the first threaded rod to adjust the distance between the clamping blocks. Rotating the first threaded rod allows for flexible adjustment of the distance between multiple clamping blocks, making it suitable for steel columns of different diameters. This eliminates the need to customize clamping components for steel columns of different sizes, improving the versatility of the device. The design of adjusting the distance between the upper and lower devices using the second threaded rod allows for precise adjustment of the distance between the upper and lower devices in a double steel column scenario. Finally, the upper device is fixed, and the vertical distance between the two steel columns can be flexibly set according to actual needs, adapting to different installation height requirements.

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: like Figures 1 to 5 As shown, the preferred embodiment of the steel column quick positioning and installation device of this utility model includes: an upper device, which includes a fixing plate 1. A first slot 2 is opened in the center of the fixing plate 1. A plurality of second slots 3 are symmetrically arranged on the outer side of the first slot 2, and each second slot 3 is interconnected with the first slot 2. A third slot 4 is opened on one side of the inner wall of each second slot 3. The third slot 4 is interconnected with the second slot 3. A sliding plate 5 is slidably installed on the inner wall of the third slot 4. A support column 6 is fixedly connected to one side of the sliding plate 5. A locking mechanism 7 is fixedly connected to the upper end of the support column 6. A steel column body 8 is slidably installed on the side of the plurality of locking mechanisms 7 that are close to each other. The inner wall of the third slot 4 is in contact with the side wall of the sliding plate 5, and the inner wall of the second slot 3 is in contact with the side wall of the support column 6.

[0017] Furthermore, the locking mechanism 7 includes a limiting block 71 fixedly mounted on the upper end of the support column 6. A fixing block 72 is provided on the outer side of the limiting block 71. The fixing block 72 has a first threaded hole 73 extending through it. The limiting block 71 has a second threaded hole 76 corresponding to the first threaded hole 73 extending through it. The first threaded hole 73 and the second threaded hole 76 are interconnected. A first threaded rod 74 is threadedly installed on the inner wall of the first threaded hole 73. The inner end of the first threaded rod 74 passes through the first threaded hole 73 and extends to the inner side of the second threaded hole 76. A clamping block 75 is fixedly connected to the inner end of the first threaded rod 74. The side of the multiple clamping blocks 75 that is close to each other is set as an arc surface, and the arc surface has anti-slip grooves.

[0018] Furthermore, the upper end of the fixing plate 1 is provided with multiple third screw holes 9, which correspond to multiple third slots 4. The upper end of the sliding plate 5 is provided with a fourth screw hole 10, which is interconnected with the third screw holes 9. A bolt 11 is threaded onto the inner wall of the third screw hole 9, with one end of the bolt 11 extending to the inner wall of the fourth screw hole 10. The four corners of the upper end of the fixing plate 1 are provided with fifth screw holes 12, and a second threaded rod 13 is installed in the fifth screw hole 12. The lower end of the second threaded rod 13 is connected to the lower device, and the lower device and the upper device are symmetrically arranged with respect to the center point of the second threaded rod 13. The inner wall of the third slot 4 is in contact with the side wall of the sliding plate 5, and the inner wall of the second slot 3 is in contact with the side wall of the support column 6.

[0019] The first slot 2, second slot 3, and third slot 4 on the fixing plate 1 of this utility model form a multi-level sliding channel. The sliding plate 5 can slide within the third slot 4. The support column 6 achieves vertical position adjustment through the through structure of the second slot 3 and the third slot 4. With the bolt 11 passing through the third screw hole 9 and the fourth screw hole 10 to lock the sliding plate 5, the position of the support column 6 can be precisely fixed, adapting to the steel column positioning requirements in different installation scenarios. The locking mechanism 7 drives the clamping blocks 75 on both sides to tighten synchronously through the first threaded rod 74. The arc surface design and anti-slip groove of the clamping block 75 increase the friction with the steel column body, ensuring a firm clamping. The through design of the first screw hole 73 and the second screw hole 76 makes the transmission of the first threaded rod 74 smoother, avoiding clamping deviation caused by uneven force on one side.

[0020] Furthermore, when machining this device, the machining accuracy of the slots and sliding parts should be improved (e.g., CNC milling should be used to control the tolerance to ≤0.2mm), high-strength bolts (e.g., grade 8.8 or 10.9) should be used, and high-strength alloys (e.g., Q460 or stainless steel) can be used for the support columns and sliding plates.

[0021] Example 2: The following describes how to use this device: For single steel column ground positioning installation scenarios, only the upper device is needed. First, the fixing plate 1 is fixed to the ground position by the cooperation of the second threaded rod 13 and the fifth screw hole 12. Since the first slot 2 and the second slot 3 are interconnected, multiple sliding plates 5 can be slidably installed on the inner walls of the multiple second slots 3 respectively through these two slots. Then, the sliding plates 5 are fixed inside the fixing plate 1 using bolts 11. After fixing the sliding plates 5, the first threaded rod 74 is rotated to adjust the spacing between the multiple clamping blocks 75. Finally, the steel column is placed in the middle of the multiple clamping blocks 75. For two steel column positioning installation scenarios, first, following the operation method described above for the ground scenario, the lower device is installed on the upper end of the first steel column; then, the second threaded rod 13 is rotated to adjust the distance between the upper and lower devices; then, referring to the operation of adjusting the spacing of the clamping blocks 75 described above, the second steel column is installed in the middle of the multiple clamping blocks 75 of the upper device.
