Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a prefabricated steel structure assembly position correction device. Background Technology

[0002] In the field of civil engineering construction, steel structures are mainly composed of columns, longitudinal beams, transverse beams, purlins, and various types of steel plates and connectors. After design, they are uniformly produced and processed by steel structure manufacturers, transported to the construction site, and assembled on-site by workers, and then hoisted and assembled at high altitude. The connection methods are mainly high-strength bolt connections and welding, with a small part using prefabricated structures.

[0003] Because steel structures are generally smaller in size than similar concrete structures, yet bear greater loads, their fabrication and installation require higher precision, especially in welding. Even a slight deviation in the welding position can alter the stress on the steel structure, causing it to bear loads exceeding the design specifications. In bolted connections, misalignment of the connection position can cause misalignment of pre-drilled holes, preventing bolts from being inserted or tightened to the required torque, thus hindering the assembly and installation of the steel structure or resulting in insufficient connection strength.

[0004] In current installation methods, the components to be installed are lifted by a crane and suspended in the air before installation. At this time, the components are easily affected by wind, thrust, or the lifting and braking operations of the crane, as they have no other support. They are basically in an unstable state, resulting in inaccurate installation positions. This has a significant impact on both welding and bolted connections. Therefore, how to stably place the components to be installed at the pre-installation height and further correct their positions to improve installation accuracy is an urgent problem to be solved.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this invention is to provide a prefabricated steel structure assembly position correction device, which can stably place the components to be installed at a pre-installation height and further correct their positions to improve installation accuracy.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-4 As shown, this utility model provides a prefabricated steel structure assembly position correction device, including a support component and a correction component; wherein the support component is installed on the steel structure column;

[0035] The correction assembly includes a correction plate 1 that is perpendicular to the steel structure column and detachably mounted on the support assembly. Two fixing plates 11 are vertically fixed on the top surface of the correction plate 1. In use, the component to be installed is placed on the top surface of the correction plate 1 and located between the two fixing plates 11. Each of the two fixing plates 11 is provided with a horizontal adjustment knob 12 that is movable along its thickness direction and used to push the component to be installed.

[0036] In use, the support assembly is fixed at the pre-installation position of the steel structure column, the correction assembly is installed on the support assembly, and the component to be installed is hoisted and placed on the correction plate 1 of the correction assembly, so that the component to be installed is stably supported and is not affected by wind or other factors. By adjusting the horizontal adjustment knobs 12 on the two fixed plates 11, the component to be installed is pushed to slide on the correction plate 1, so that the component to be installed is moved to a more precise installation position and clamped and fixed by the horizontal adjustment knobs 12 on the two fixed plates 11, thereby making the installation position of the component to be installed more precise and stable, which facilitates bolt connection or welding.

[0037] As an example of an implementable approach, such as Figures 1-4 As shown, a first threaded hole 111 can be provided on the fixing plate 11. The component to be installed is pushed and clamped by threading the horizontal adjustment knob 12 into the first threaded hole 111 and placing one end of the knob directly or indirectly against the receiving installation component.

[0038] As an example of an implementable approach, such as Figures 1-4 As shown, a pad 13 is provided between the two fixing plates 11 and the component to be installed. The horizontal adjustment knob 12 indirectly pushes the component to be installed by pushing the pad 13, which effectively avoids the horizontal adjustment knob 12 scratching the component to be installed. Furthermore, pads 13 of different thicknesses can be selected according to the gap between the component to be installed and the fixing plate 11, reducing the adjustment stroke of the horizontal adjustment knob 12 and thus improving the efficiency of adjusting the position of the component to be installed.

[0039] As an example of an implementable approach, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the support assembly includes two opposing L-shaped support frames 2, each L-shaped support frame 2 comprising a vertical plate 21 and a horizontal plate 22; the two vertical plates 21 are clamped onto the steel structure column by a detachable connection structure, and a correction plate 1 is installed on the horizontal plate 22; the detachable connection structure includes an adjustment plate 3 and at least two sliding legs 31 vertically fixed to the adjustment plate 3; the two vertical plates 21 are provided with second through holes 24 for the sliding legs 31 to pass through, so that the sliding legs 31 and the two vertical plates 21 together form a rectangular frame structure surrounding the steel structure column; the end of the sliding leg 31 away from the adjustment plate 3 is provided with a first limiting structure to limit the displacement of the vertical plate 21; wherein the second limiting mechanism can be a screw... The adjusting plate 3 is equipped with a fastening knob 32 that is movable along its thickness direction and used to push the vertical plate 21 to drive the two vertical plates 21 to clamp the steel structure column. A third threaded hole 33 can be provided on the vertical plate 21. By threading the fastening knob 32 into the third threaded hole 33 and placing one end of it directly or indirectly against the vertical plate 21, the two vertical plates 21 can be driven to clamp the steel structure column. By setting a detachable support component, the installation of the support component is convenient and the installation efficiency is improved. The fastening knob 32 can adjust the distance between the two vertical plates 21, so that the support component can be used for different types of steel structure columns, improving the compatibility of the correction device.

[0040] As an example of an implementable approach, such as Figures 1-6As shown, the correction assembly also includes a positioning rod 14 vertically fixed to the bottom surface of the correction plate 1. The horizontal plate 22 is provided with a first through hole 23 for the positioning rod 14 to slide through. The horizontal plate 22 is also provided with a height adjustment knob 15 that is movable along its thickness direction and used to push the correction plate 1. A second threaded hole 221 can be provided on the horizontal plate 22. By threading the height adjustment knob 15 into the second threaded hole 221 and placing one end of it directly or indirectly against the bottom surface of the correction plate 1, the height of the correction plate 1 can be adjusted. This allows the component to be installed to be finely adjusted in height on the correction plate 1, further improving the installation accuracy of the component. The sliding cooperation between the positioning rod 14 and the first through hole 23 limits the movement direction of the correction plate 1, improving the stability of the correction device.

[0041] As an example of an implementable approach, such as Figure 6 As shown, a limiting support 25 is fixed on the side of the vertical plate 21 that abuts against the fastening knob 32. A blind hole coaxial with the fastening knob 32 is provided in the limiting support 25. The end of the fastening knob 32 extends into the blind hole to prevent it from radially deviating, thereby improving the stability of the correction device.

[0042] As an example of an implementable approach, such as Figure 1 , Figure 2 As shown, a reinforcing plate 26 is welded and fixed between the vertical plate 21 and the horizontal plate 22 of the L-shaped support frame 2, which improves the strength of the correction device.

[0043] As an example of implementation, the positioning rod 14 can be a cylindrical rod with a second limiting structure located below the horizontal plate 22 at the end away from the correction plate 1 to prevent the correction plate 1 from falling off. The second limiting mechanism can be a nut or a positioning pin to prevent the correction plate 1 from falling off, thereby improving the safety of the correction device.

[0044] As an example of an implementable approach, such as Figures 1-4 As shown, there are four sliding legs 31 and four positioning rods 14; they are evenly distributed around the center of gravity of the adjusting plate 3 and the correcting plate 1, respectively. Each fixed plate 11 is provided with at least two horizontal adjustment knobs 12, as shown in the figure, which effectively improves the stability of the correcting device.

[0045] As an example of implementation, the height adjustment knob 15 is driven by a first gear set located on the side of the correction plate 1 away from the sliding leg 31; the fastening knob 32 is driven by a second gear set located on the bottom surface of the horizontal plate 22; and the leveling knob 12 is driven by a third gear set located on the side of the fixing plate 11 away from the component to be installed. The first, second, and third gear sets are all reduction gear sets, and the height adjustment knob 15, fastening knob 32, and leveling knob 12 are indirectly adjusted via the first, second, and third gear sets respectively, making adjustment more effortless and more accurate.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
