Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a high-strength steel structure box column component. Background Technology

[0002] Currently, the joints of box-type steel columns widely employ a double-clamp bolt connection method with upper and lower ear plates for positioning. This involves welding upper and lower ear plates to the joint, clamping the ear plates with bolts to achieve initial positioning, and then welding them in place. After welding, the bolted connection components need to be disassembled and cut. However, this traditional connection method has the following problems:

[0003] First, the positioning deviation caused by construction errors is significant. Traditional double-plate bolted connections rely on manual measurement and installation, making it difficult to avoid errors due to limitations in measuring tool accuracy and variations in operator skill levels. In high-rise building construction, box-type columns can be installed at heights of tens or even hundreds of meters; even small positioning deviations can accumulate after multiple layers are joined. Furthermore, if the bolt holes on the ear plates are misaligned during bolting, bolts may not be able to be inserted smoothly. Forced installation will create additional stress on the box-type column, affecting the structure's load-bearing capacity and service life.

[0004] Secondly, the large number of welded and bolted components increases construction complexity and cost. Traditional connection methods require welding upper and lower lugs at the joints of box-type columns. Each lug is typically equipped with multiple sets of double clamps and bolts to ensure positioning stability. The extensive welding work not only consumes large amounts of steel and welding materials but also increases material procurement costs and warehousing management difficulties, hindering project cost control.

[0005] Furthermore, the installation and dismantling processes are time-consuming and labor-intensive, severely impacting construction efficiency. During installation, multiple steps must be completed sequentially, including welding the ear plates, installing the double clamps, and tightening the bolts. Each step requires precise operation and inspection, making the process cumbersome. During dismantling, since the bolts and clamps no longer bear structural loads after welding, they must be cut and removed. This cutting process not only easily damages the box-type column base material but also requires a significant investment of manpower and time. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a high-strength steel structure box column component, which solves the problems of box-type steel column splicing using upper and lower ear plates double clamp bolt connection for positioning and then welding and fixing, which are prone to positioning deviation due to construction errors, complex construction and high cost due to the large number of welding and bolt connection parts, and cumbersome, time-consuming and labor-intensive installation and disassembly steps.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength steel structure box-type column component, comprising a quick positioning mechanism, wherein the quick positioning mechanism comprises a connecting frame, the connecting frame comprising an integrally formed clamping plate section, an extension section, and a connecting seat, the clamping plate section being fitted onto both sides of the ear plate, the ear plate being welded to the four vertical sides of a box-type column, a nut being welded onto the connecting seat, and a tapered bolt being threaded onto the nut, the tapered end of the tapered bolt being adapted to be inserted into a positioning hole, the positioning hole being opened on the four vertical sides of another box-type column, and the two box-type columns being arranged vertically connected.

[0008] The beneficial effects of this utility model are as follows: After the quick positioning mechanism is installed on a box column by welding and bolting, the nut is turned to make the nut cooperate with the positioning hole opened on another box column, thereby realizing the adjustment and locking of the position of the other box column, thereby improving the connection efficiency between the two box columns.

[0009] To facilitate the installation of the rapid positioning mechanism;

[0010] As a further improvement to the above technical solution: the extension section is disposed between the clamping plate section and the connecting seat, and the upper end of the extension section is inclined away from the box-shaped column.

[0011] The beneficial effects of this improvement are: by setting the extension section, a sufficient horizontal distance can be maintained between the connecting seat and the box column, so that when the connecting frame is bolted to one box column, it maintains a sufficient distance from the other box column, thus facilitating the installation of the connecting frame.

[0012] To ensure the stability of the connecting frame's support for the nuts and tapered bolts;

[0013] As a further improvement to the above technical solution: the connecting seat is a channel steel structure, the outer extension connects the two flanges of the connecting seat, and the two sides of the nut are attached to and welded to the inner walls of the two flanges of the connecting seat.

[0014] The beneficial effect of this improvement is that the connecting seat can provide a stable support for the nut and the tapered bolt, thereby ensuring the stability of the quick positioning mechanism's support for the upper box column.

[0015] To further improve the support strength of the rapid positioning mechanism for the box-shaped column;

[0016] As a further improvement to the above technical solution: the number of nuts welded on each of the connecting seats is not less than two.

[0017] The beneficial effects of this improvement are: multiple tapered bolts can be inserted into the positioning holes, providing stable positioning support for the box-shaped column.

[0018] To ensure the accuracy of the conical bolts in positioning the box-shaped column;

[0019] As a further improvement to the above technical solution: the diameter of the positioning hole is not less than the diameter of the upper base of the tapered end of the tapered bolt and not greater than the diameter of the lower base of the tapered end of the tapered bolt.

[0020] The beneficial effects of this improvement are as follows: After the positioning holes are precisely machined on the box-shaped column using laser or drilling, during the assembly of the box-shaped columns, as the tapered bolt is tightened and moves towards the box-shaped column, the tapered end of the tapered bolt slides into contact with the inner wall of the positioning hole, and the inclined part of the tapered end pushes the positioning hole, thereby making the two box-shaped columns precisely aligned.

[0021] To ensure the stability of the connection between the clamping plate section and the ear plate;

[0022] As a further improvement to the above technical solution: the two sides of the ear plate are slidably connected to one side of the clamping plate section, and the clamping plate section and the ear plate are provided with multiple through holes for fitting plug-in connecting bolts.

[0023] The beneficial effect of this improvement is that the clamping plate section and the ear plate can be stably connected under the action of the connecting bolts.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way. Example 1:

[0031] like Figure 1 As shown in Figure 4: A high-strength steel structure box-type column component includes a quick positioning mechanism 5. The quick positioning mechanism 5 includes a connecting frame 6, which includes an integrally formed clamping plate section 61, an extension section 62, and a connecting seat 63. The clamping plate section 61 is fitted onto both sides of the ear plate 2. The ear plate 2 is welded to the four vertical sides of a box-type column 1. Nuts 7 are welded onto the connecting seat 63, and tapered bolts 8 are threaded onto the nuts 7. The tapered ends of the tapered bolts 8 are fitted into positioning holes 9, which are opened on the four vertical sides of another box-type column 1. The two box-type columns 1 are vertically joined together. After the component 5 is installed on one box-shaped column 1 by welding and bolting, the nut 7 is tightened to engage with the positioning hole 9 on another box-shaped column 1, thereby adjusting and locking the position of the other box-shaped column 1, thus improving the connection efficiency between the two box-shaped columns 1. The extension section 62 is located between the clamping plate section 61 and the connecting seat 63. The upper end of the extension section 62 is inclined away from the box-shaped column 1. The setting of the extension section 62 ensures that the connecting seat 63 and the box-shaped column 1 maintain a sufficient horizontal distance, so that when the connecting frame 6 is bolted to one box-shaped column 1, it maintains a sufficient distance from the other box-shaped column 1. This facilitates the installation of the connecting bracket 6. The connecting seat 63 is a channel steel structure. The outer extension 62 connects the two flanges of the connecting seat 63. The two sides of the nut 7 are attached to and welded to the inner walls of the two flanges of the connecting seat 63. The connecting seat 63 provides stable support for the nut 7 and the tapered bolt 8, thereby ensuring the stability of the quick positioning mechanism 5 supporting the upper box column 1. The number of nuts 7 welded on each connecting seat 63 is not less than two. Multiple tapered bolts 8 can be inserted into the positioning holes 9 to stably position and support the box column 1. The diameter of the positioning hole 9 is not less than the diameter of the upper base of the tapered end of the tapered bolt 8 and not greater than the diameter of the tapered head. The diameter of the bottom of the tapered end of the bolt 8 is precisely machined into the positioning hole 9 on the box column 1 using laser or drilling. During the splicing of the box column 1, as the tapered bolt 8 is tightened, it moves towards the box column 1. The tapered end of the tapered bolt 8 slides into contact with the inner wall of the positioning hole 9. The inclined part of the tapered end pushes the positioning hole 9, thereby making the two box columns 1 precisely aligned. The two sides of the ear plate 2 are slidably connected to one side of the clamping plate section 61. The clamping plate section 61 and the ear plate 2 have multiple through holes for fitting the insertion connecting bolts 4. The clamping plate section 61 and the ear plate 2 can be stably connected under the action of the connecting bolts 4.

[0032] The working principle of this technical solution is as follows: Ear plates 2 are welded onto one box-shaped column 1, and positioning holes 9 are precisely drilled on another box-shaped column 1. Then, clamping plate segments 61 are fitted onto both sides of the ear plates 2, aligning the through holes on the clamping plate segments 61 and the ear plates 2. Connecting bolts 4 are passed through the through holes and tightened sequentially to ensure a secure connection between the clamping plate segments 61 and the ear plates 2. The other box-shaped column 1 is then hoisted to the splicing position, aligning the two box-shaped columns 1 vertically. The verticality and horizontality of the box-shaped columns 1 are initially adjusted using measuring instruments such as a level and total station to ensure they are in approximately accurate positions. At this point, the conical bolts 8 on the connecting frame 6 are initially aligned with the positioning holes 9 on the side of the other box-shaped column 1. The conical bolts 8 are then tightened. This causes the cone bolt 8 to move towards the box column 1. As it is tightened, the conical end of the cone bolt 8 slides into contact with the inner wall of the positioning hole 9. The inclined part of the conical end pushes the positioning hole 9, thereby making the two box columns 1 precisely aligned. Then, the cone bolt 8 is further tightened so that multiple cone bolts 8 are inserted into the positioning hole 9, providing a stable positioning support for the box column 1. During the tightening process, it is necessary to ensure that the tightening degree of each cone bolt 8 is consistent to avoid deformation of the box column 1 or loosening of the connection due to uneven force. After the cone bolt 8 is tightened, the connection gap between the two box columns 1 is welded. Then, the weld between the ear plate 2 and the box column 1 is cut to complete the separation of the quick positioning mechanism 5 from the box column 1.
