Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology in building engineering, and in particular to an adjustable steel column installation and welding operation platform and its usage method. Background Technology

[0002] During steel structure construction, a large number of box-shaped steel columns of various cross sections are used. The steel columns need to be segmented during installation. The segmented positions must be connected, aligned, and welded at high altitudes. Due to the limited space for high-altitude operations, the operation is difficult and poses a great safety hazard. Furthermore, it is impossible to guarantee the accuracy of installation and alignment as well as the quality of welds.

[0003] Traditional steel column installation welding operation platforms mainly fall into the following types: ① The platform components are directly welded together as a whole, and holes are drilled in the base according to the steel column cross-section. This method simplifies platform assembly, but on-site installation and dismantling require fitting the platform from the top of the steel column, which is quite difficult in practice. Lifting lugs are installed on the top and side walls of the steel column, and the size of the base opening needs to take into account the width of the lifting lugs, resulting in an actual opening size larger than the steel column cross-section. Without additional measures, a large gap will be created between the platform and the steel column wall after installation, and welding sparks and various small tools will fall through the gap, causing risks such as falling from heights and falling objects. The platform is assembled by welding, and after the project is completed, the platform can only be dismantled by flame cutting, which damages the platform components, making them unusable and resulting in material waste. The fixed opening size of the base means that this platform can only be used for steel columns with fixed cross-sections. There are many types of steel column cross-sections for the same project, requiring the manufacture of multiple operation platforms of different sizes, resulting in redundancy of platform types on site, increased costs, and workers need to distinguish them during on-site installation, which is inconvenient for on-site use and temporary storage. ② The platform components are connected by bolts, with an opening on one side. During installation and disassembly, they can be inserted through the side wall of the steel column. This method of installation is more convenient. The bolt connection method of the platform makes disassembly more convenient and can be reused. However, since the opening size of the base cannot be adjusted, it can only be used for steel columns with fixed cross-sections. This will also lead to the need to manufacture multiple operating platforms of different sizes for the same project, resulting in redundancy of platform types on site and increased costs.

[0004] Therefore, developing an operating platform that can solve the problems of difficult installation and dismantling of existing steel column welding operating platforms, the wide variety of platforms in the same project, and the inability to reuse them after dismantling is one of the important issues that need to be addressed. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the purpose of the present invention is to solve the above problems. The present invention provides an adjustable steel column installation and welding operation platform that is easy to install and dismantle, and can be reused after disassembly.

[0006] Another objective of this invention is to provide a method for using an adjustable steel column installation and welding operation platform.

[0007] To solve the above problems, the present invention adopts the following technical solution: an adjustable steel column installation and welding operation platform, wherein the platform is installed on the steel column, the platform includes an integral platform base, the center of which is hollow to accommodate the steel column, and the integral platform base is assembled from a first platform base, a second platform base, and a third platform base; platform railings are vertically installed on the integral platform base, and adjustable railing sections are provided between the platform railings; the integral platform base, platform railings, and adjustable railing sections are combined to form the operation platform. The platform bottom of this application is assembled from the first platform base, the second platform base, and the third platform base, making the assembly of the entire platform more convenient; after use, each platform can be disassembled to disassemble the operation platform; it will not damage the components of the operation platform, can be reused for unused projects, is easy to operate, and has a wide range of applications.

[0008] Furthermore, the platform railing includes a railing frame, which is assembled into an L-shaped frame. Perforated plates are installed within the frame, and two platform railings are spliced ​​together to form a concave railing, which serves as the railing for either side of the operating platform. The concave railings are vertically mounted on the platform's overall base, spliced ​​in pairs. This design, by placing perforated plates within the railing frame and fitting corresponding shaped perforated plates into the assembled frame, facilitates assembly. Furthermore, by modularizing the platform railings, the platform railings can be disassembled after use without damaging any components.

[0009] Furthermore, the guardrail frame is provided with slots. After the two L-shaped frames are spliced, the slots on the guardrail frame are horizontally parallel, and the railing adjustment section is located on the slot. Using this solution, the slots are pre-set, and the railing adjustment section is installed based on the slots after the platform guardrail is spliced. This ensures installation accuracy, and at the same time, it is easy to remove when needed, making the operation convenient.

[0010] Furthermore, the first platform base includes a first steel channel frame, which is assembled into a planar frame. A first base guardrail connecting plate is provided at the edge of the first steel channel frame. The connecting plate includes connecting holes, through which the connecting plate connects to the first steel channel frame and the platform guardrail respectively. This solution allows the first platform base to be assembled from a detachable frame, making installation more flexible. The frame can be assembled into the required shape and structure according to different project needs, making it widely applicable. It is also easy to disassemble; after project completion, the first platform base can be disassembled by removing the first steel channel frame. Furthermore, the disassembled components are easy to classify and store without damaging them.

[0011] Furthermore, the second platform base includes a second steel channel frame, which is assembled into a planar frame. A second base guardrail connecting plate is provided at the edge of the second steel channel frame. The connecting plate includes connecting holes, through which the connecting plate connects to the second steel channel frame and the platform guardrail respectively. This solution allows the second platform base to be assembled from a detachable frame, making installation more flexible. The frame can be assembled into the required shape and structure according to different project needs, making it widely applicable. It is also easy to disassemble; after project completion, the second platform base can be disassembled by separately removing the second steel channel frame. Furthermore, the disassembled components are easy to classify and store without damaging the parts.

[0012] Furthermore, the first and second steel channel frames are connected by connecting channel steel. Positioning holes are provided on both the first and second steel channel frames, and the connecting channel steel fixes the distance between the two frames through these holes. This design allows for adjustment of the size of the first and second platform bases, tailored to the cross-sectional area of ​​different steel columns, further enhancing the flexibility of the operating platform.

[0013] Furthermore, the steel column supports the overall platform base via a triangular support. The triangular support comprises a square tube frame assembled into a right-angled triangle, with one right-angled side connected to the steel column and the other right-angled side supporting the overall platform base. In some cases, the steel column may lack supporting brackets; this solution allows for the rapid installation of the steel column support.

[0014] Furthermore, the right-angled sides of the triangular support connected to the steel column are respectively provided with an upper plate and a lower plate. The upper plate is an L-shaped plate, including a vertically downward-pointing card. A concave triangular bracket slot is fixedly connected to the steel column. The triangular bracket slot and the side wall of the steel column form a groove for inserting the upper plate. The vertically downward-pointing card of the upper plate is inserted into the groove.

[0015] The lower clamping plate is positioned perpendicular to the right-angled side of the triangular support, and its length is equal to the thickness of the triangular frame slot. Using this design, the steel column and triangular support are fixed by inserting the upper clamping plate into the triangular frame slot, while the lower clamping plate abuts against the side wall of the steel column, effectively supporting the overall platform base.

[0016] This application also provides a method for using an adjustable steel column installation and welding platform, the specific steps of which include:

[0017] Step 1: Open the third platform base so that the center of the platform base and the open position form an outward extending channel. Insert the operating platform into the channel from the side of the steel column.

[0018] Step 2: After the operating platform is in place, close the third base downwards. The overall platform base assembly is complete. Install the railing adjustment section on the platform railing.

[0019] Step 3: The platform railings are connected to each other using bolt holes; the platform railings are connected to the first platform base and the second platform base using the first base railing connecting plate and the second base railing connecting plate.

[0020] Step 4: Place the adjustable section of the railing into the slot on the platform railing;

[0021] Step 5: After using the operating platform, remove all connecting bolts between the components, disassemble the platform, and store it neatly. This method, by fitting the operating platform through the side wall of the steel column, makes the installation process safer.

[0022] Furthermore, before installing the operating platform, the cross-sectional dimensions of the steel column are measured. If the steel column cross-section is larger than the minimum opening size at the center of the operating platform, the overall base plate of the operating platform is stretched. Specifically, the distance between the first platform base and the second platform base is increased, and they are connected by a connecting channel steel. After stretching to the required size, the first platform base, the second platform base, and the positioning holes on the connecting channel steel are tightened and fixed with bolts. Using this solution, the method provided in this application can be applied to different steel column cross-sections, increasing its applicability.

[0023] Working Principle: This application provides an adjustable steel column installation and welding operation platform. The platform is installed on a steel column and includes an integral platform base with a hollow center to accommodate the steel column. The integral platform base is assembled from a first platform base, a second platform base, and a third platform base. Platform railings are vertically installed on the integral platform base, and adjustable railing sections are provided between the railings. The integral platform base, platform railings, and adjustable railing sections combine to form the operation platform. The bottom of the platform is assembled from the first, second, and third platform bases. After use, each platform can be disassembled to disassemble the operation platform without damaging any components. It can be reused for unused projects, is easy to operate, and has a wide range of applications. By movably connecting the third platform base to the first and second platform bases, and opening the third platform base before installation, the operation platform can be inserted through the side wall of the steel column, making the installation process safer and the assembly of the entire platform more convenient.

[0024] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0026] 2. This application places perforated plates inside the guardrail frame. The perforated plates of the corresponding shapes are placed inside the assembled frame, which is easy to assemble. By adopting this solution, the grid platform guardrail is modularized. After use, each guardrail can be removed to complete the disassembly of the platform guardrail without causing damage to the guardrail components.

[0027] 3. This application designs the first platform base and the second platform base as being assembled from a first steel channel frame and a second steel channel frame. The edges of the first and second steel channel frames are provided with first and second base guardrail connecting plates, respectively. These connecting plates connect to the first and second steel channel frames and the platform guardrail through connecting holes. This makes the installation of the operating platform more flexible, allowing the frames to be assembled into the required shapes and structures according to different project needs, thus having a wide range of applications. Furthermore, it is easy to disassemble; after the project is completed, the first platform base plate can be disassembled by separately removing the first steel channel frame.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] Example

[0048] like Figure 1 , Figure 2 As shown, this application provides an adjustable steel column 2 installation and welding operation platform 1 to solve the problems of difficulty in installing and dismantling existing steel column 2 welding operation platforms 1, the wide variety of platforms in the same project, and the inability to reuse them after dismantling. Specifically, the operation platform 1 described in this application is installed on brackets set around the perimeter of the steel column 2. The brackets are fixed to the side wall of the steel column 2 to support the operation platform 1. The operation platform 1 includes an integral platform base with a hollow center to accommodate the steel column 2. In the installed state, the steel column 2 is located at the center of the integral platform base. The integral platform base is assembled from a first platform base 5, a second platform base 6, and a third platform base 7. Platform railings 4 are vertically installed on the integral platform base, and adjustable railing sections 8 are provided between the platform railings 4. The integral platform base, platform railings 4, and adjustable railing sections 8 combine to form the operation platform 1. The platform of this application is composed of a first platform base 5, a second platform base 6, and a third platform base 7, which makes the assembly of the entire platform more convenient. After use, each platform can be disassembled to disassemble the operating platform 1. It will not damage any parts of the operating platform 1. It can be reused for unused projects, is easy to operate, and has a wide range of applications.

[0049] like Figure 4 As shown, the platform railing 4 includes a railing frame 13, which is assembled into an L-shaped frame. Perforated plates 17 are provided within the frame. Two platform railings 4 are spliced ​​together to form a concave railing, which serves as the railing on either side of the operating platform 1. The concave railings are vertically mounted on the platform's overall base, spliced ​​in pairs. This application utilizes perforated plates 17 placed within the railing frame 13, with corresponding shaped perforated plates 17 positioned within the assembled frame. Assembly is convenient. By modularizing the platform railing 4, after use, each railing can be disassembled, thus completing the disassembly of the platform railing 4 without damaging any components.

[0050] In some embodiments, such as Figure 8 (a) Figure 9 As shown in (a), the guardrail frame 13 is provided with a slot 14. Preferably, the slot 14 is a U-shaped slot 14. After the two L-shaped frames are spliced, the slots 14 on the guardrail frame 13 are horizontally parallel, and the railing adjustment section 8 is provided on the slot 14. This application ensures the accuracy of installation by pre-setting the slot 14 and installing the railing adjustment section 8 based on the slot 14 after the platform guardrail 4 is spliced. At the same time, it is easy to remove when it needs to be removed, and the operation is convenient. In some preferred embodiments, the railing adjustment section 8 is a telescopic structure. In some cases, Figure 8 (b) Figure 9 As shown in (b), the spacing of the platform guardrail 4 may need to be increased during installation. In this case, different spacing of the platform guardrail 4 can be used in the railing stage, which can increase the applicability of the operating platform 1 and has obvious beneficial effects.

[0051] In some embodiments, such as Figure 5 , Figure 6 As shown, the first platform base 5 includes a first channel steel frame 18, which is assembled into a planar frame. A first base guardrail connecting plate 19 is provided at the edge of the first channel steel frame 18. The connecting plate includes connecting holes, and the connecting plate connects the first channel steel frame 18 and the platform guardrail 4 through the connecting holes. The second platform base 6 includes a second channel steel frame 20, which is assembled into a planar frame. A second base guardrail connecting plate 21 is provided at the edge of the second channel steel frame 20. The connecting plate includes connecting holes, and the connecting plate connects the second channel steel frame 20 and the platform guardrail 4 through the connecting holes. Figure 7As shown in (a), this application configures the first platform base 5 and the second platform base 6 as being assembled from a first channel steel frame 18 and a second channel steel frame 20. The edges of the first channel steel frame 18 and the second channel steel frame 20 are provided with a first base guardrail connecting plate 19 and a second base guardrail connecting plate 21, respectively. The connecting plates are connected to the first channel steel frame 18, the second channel steel frame 20, and the platform guardrail 4 through connecting holes. This makes the installation of the operating platform 1 more flexible, allowing the frame to be assembled into the required shape and structure according to different project needs, thus having a wide range of applications. Furthermore, it is easy to disassemble; after the project is completed, the first platform base plate can be disassembled by disassembling the first channel steel frame 18, and the disassembled components are easy to classify and store without damaging the parts.

[0052] Different engineering projects have different cross-sectional sizes for the steel columns 2. In some cases, the first channel steel frame 18 and the second channel steel frame 20 are connected by connecting channel steel 22, such as... Figure 7 As shown, the first channel steel frame 18 and the second channel steel frame 20 are equipped with positioning holes, and the connecting channel steel 22 fixes the distance between the two frames through the positioning holes. Figure 7 As shown in (b), this application uses connecting steel channels and connects the first channel steel frame 18 and the second channel steel frame 20 to adjust the size of the first platform base 5 and the second platform base 6. This application can be adjusted according to the cross-sectional area of ​​different steel columns 2, further improving the flexibility of the operation platform 1.

[0053] In some cases, such as Figure 3 As shown, steel column 2 may have incomplete bracket installation. The steel column 2 supports the entire platform base via a triangular support 3. The triangular support 3 includes a square tube frame 12, which is assembled into a right-angled triangle. One right-angled side of the triangle connects to the steel column 2; the other right-angled side supports the entire platform base. In some cases, steel column 2 may lack bracket installation. This solution allows for the rapid installation of the support portion of steel column 2.

[0054] Specifically, the right-angled sides of the triangular support 3 connected to the steel column 2 are respectively provided with an upper plate 10 and a lower plate 11. The upper plate 10 is an L-shaped plate, including a vertically downward card. A concave triangular bracket slot 149 is fixedly connected to the steel column 2. The triangular bracket slot 149 and the side wall of the steel column 2 form a slot for the upper plate 10 to be inserted. The vertically downward card of the upper plate 10 is inserted into the slot.

[0055] The lower clamping plate 11 is set perpendicular to the right-angled side of the triangular support 3, and its length is equal to the thickness of the triangular bracket slot 149. Using this solution, by inserting the upper clamping plate 10 into the triangular bracket slot 149, the steel column 2 and the triangular support 3 are fixed together. The lower clamping plate 11 abuts against the side wall of the steel column 2, thus achieving effective support of the triangular support 3 for the overall platform base.

[0056] Example 2

[0057] like Figure 10 As shown, a method for using an adjustable steel column 2 installation and welding operation platform 1 includes the following steps:

[0058] Step 1: Open the third platform base 7 so that the center of the platform base and the open position form an outward extending channel. The operating platform 1 is inserted into the channel from the side of the steel column 2.

[0059] Step 2: After the operating platform 1 is in place, close the third base downwards. The overall platform base splicing is completed. Install the railing adjustment section 8 on the platform railing 4.

[0060] Step 3: The platform guardrails 4 are connected by bolt holes; the platform guardrails 4 are connected to the first platform base 5 and the second platform base 6 by the first base guardrail connecting plate 19 and the second base guardrail connecting plate 21.

[0061] Step 4: Place the railing adjustment section 8 into the slot 14 of the platform railing 4;

[0062] Step 5: After using the operating platform 1, remove all connecting bolts between the components, disassemble the platform, and store it together. This method, by fitting the operating platform 1 through the side wall of the steel column 2, makes the installation process safer.

[0063] Example 3

[0064] like Figure 10 As shown, a method for using an adjustable steel column 2 installation and welding operation platform 1 includes the following steps:

[0065] Step 1: Before installing the operating platform 1, measure the cross-sectional dimensions of the steel column 2. If the cross-sectional dimensions of the steel column 2 are larger than the minimum opening size at the center of the operating platform 1, then stretch the overall base plate of the operating platform 1. Specifically, increase the distance between the first platform base 5 and the second platform base 6 and connect them through the connecting channel steel 22. After stretching to the required size, tighten and fix the first platform base 5, the second platform base 6 and the positioning holes on the connecting channel steel 22 with bolts.

[0066] Step 2: Open the third platform base 7 so that the center of the platform base and the open position form an outward extending channel, and the operating platform 1 is inserted into the channel from the side of the steel column 2.

[0067] Step 3: After the operating platform 1 is in place, close the third base downwards. The overall platform base splicing is completed. Install the railing adjustment section 8 on the platform railing 4.

[0068] Step 4: The platform guardrails 4 are connected by bolt holes; the platform guardrails 4 are connected to the first platform base 5 and the second platform base 6 by the first base guardrail connecting plate 19 and the second base guardrail connecting plate 21.

[0069] Step 5: Place the railing adjustment section 8 into the slot 14 of the platform railing 4;

[0070] Step Six: After using the operating platform 1, remove all connecting bolts between the components, disassemble the platform, and store it together. This method, by fitting the operating platform 1 through the side wall of the steel column 2, makes the installation process safer.

[0071] Finally, it should be pointed out that the above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
