[0002] Steel structure engineering occupies an important position in the modern construction field due to its high strength and lightweight, good seismic resistance and safety, convenient industrialized production and construction, high space utilization and design flexibility, environmental friendliness and sustainability, economic efficiency and cost-effectiveness, and ease of maintenance and renovation. The high strength of steel makes the structure lightweight, facilitating transportation and installation, reducing pressure on the foundation, and enabling it to withstand greater loads, making it suitable for large-span and high-rise buildings. However, during the decoration and finishing stage, masonry walls are often flush with the flanges of the I-beams, creating a problem where the web of the steel beam and the surface of the masonry wall are not on the same plane, affecting aesthetics. Furthermore, the current common practice is to fill the gaps with bricks, which not only wastes materials but also increases the weight of the steel beams, hindering its widespread use.

[0023] Reference Figure 1-2 As shown, a plastered base layer structure for ultra-high I-beam steel beams in a stairwell includes...

[0024] Extra-high I-beams 10 (greater than or equal to 800mm, referred to as "extra-high");

[0025] 20mm gypsum hollow core slabs;

[0026] An angle bracket support structure 30 is installed at the angle between the ultra-high I-beam 10 and the gypsum hollow strip 20, and is used to improve the support strength of the ultra-high I-beam 10; wherein, the angle bracket support structure 30 includes a first angle bracket 300, and a compression-resistant component is installed inside the first angle bracket 300 and used to improve the strength of the first angle bracket 300;

[0027] The second corner code 40 is connected to the first corner code 300 via a bolt 50.

[0028] When beam wrapping is required, first locate the corner bracket position, then fully weld it to the upper and lower flanges of the ultra-high I-beam 10. The spacing between each set of corner brackets is controlled at 400mm. After welding, align the gypsum hollow strip 20 with the end of the corner bracket with the hole, and make holes in the gypsum hollow strip 20. Finally, fix the gypsum hollow strip 20 with the bolt 50 to achieve beam wrapping and plastering.

[0029] It should be noted that the 400mm spacing is a convenient interval for construction and measurement, neither too large nor too small, to facilitate worker operation and ensure construction accuracy. Of course, 400mm is not limited to this, and the specific choice can be made according to the site conditions.

[0030] In this embodiment, since the upper and lower ends of the ultra-high I-beam 10 are masonry walls, it is necessary to ensure that the corner brackets have a good supporting effect so as to avoid the masonry walls from tilting.

[0031] The first corner code 300 includes a horizontal segment and a vertical segment. A plurality of positioning blocks 302 are equally spaced on the horizontal segment. The plurality of positioning blocks 302 are adapted to be inserted into the insertion blocks 402 that are equally spaced and arranged sequentially on the second corner code 40.

[0032] The vertical section is completely fitted with the gypsum hollow strip 20, and is thus connected by the bolt 50.

[0033] The first corner code member 300 has a first partition 304 and a second partition 310 inside, which divide the first corner code member 300 into three accommodating cavities of the same size; wherein,

[0034] The first receiving cavity has several interconnected protruding cavities 306 arranged in sequence inside, and several damping particles 308 of different sizes are disposed inside the protruding cavities 306.

[0035] The second receiving cavity contains several inflatable bladders 312 arranged in sequence.

[0036] The third receiving cavity contains a plurality of mounting blocks 314 arranged in sequence, a spring 316 disposed inside the mounting block 314, and a support column 318 disposed at one end of the spring 316.

[0037] A stress plate 400 is provided at the included angle of the second corner bracket 40.

[0038] The bolt 50 is provided with a mounting ring 500 and a threaded ring 504 at both ends, and a support rod 502 for supporting the second angle bracket 40 is provided on the outer ring of the mounting ring 500.

[0039] The working principle of the corner bracket support structure 30 in this embodiment is as follows:

[0040] First, the first corner bracket 300 and the second corner bracket 40 are precisely aligned and fixed through the cooperation of the positioning block 302 and the insertion block 402, ensuring the initial stability of the entire structure. The vertical section of the first corner bracket 300 is attached to the gypsum hollow strip 20 and connected by the bolt 50, further enhancing the fixing effect of the gypsum hollow strip. The bolt 50 has an installation ring 500 and a threaded ring 504 at both ends, respectively. The support rod 502 on the installation ring 500 is used to support the second corner bracket 40, providing additional support force and ensuring the tight fit between the corner brackets and the stability of the overall structure. The partitions 304 and 310 inside the first corner bracket 300 divide it into... The structure is divided into three cavities, each with a specific function. In the first cavity, the raised cavity 306 and damping particles 308 work together to absorb and reduce vibrations, improving the structure's shock absorption performance. In the second cavity, the inflatable bladder 312 can provide cushioning or adjust the stiffness of the corner bracket to adapt to different usage conditions. In the third cavity, the mounting block 314, spring 316, and support column 318 work together to provide elastic support and adjust the installation position of the corner bracket to accommodate minor errors during installation and environmental changes. A stress plate 400 is provided at the included angle of the second corner bracket 40, enhancing its structural strength and stability, ensuring it is not easily deformed under external forces. Through the synergy of these components, the entire design achieves stable coverage and fixation of the ultra-high I-beam 10, while providing necessary shock absorption and support functions, ensuring the long-term stability and safety of the structure. This design not only improves installation accuracy and load-bearing capacity but also enhances the structure's seismic performance, making it suitable for building structures requiring high precision and stability.

[0041] This utility model also includes a construction method for a plastering base layer for wrapping beams with ultra-high I-beams in stairwells, the steps of which are as follows:

[0042] S1. First, the positions of the positioning brackets on the upper and lower flanges of the ultra-high I-beam 10 need to be determined.

[0043] S2. Fully weld the corner brackets to the upper and lower flanges of the ultra-high I-beam 10 to ensure a firm connection. The spacing between each set of corner brackets should be controlled at around 400mm.

[0044] S3. After welding the corner bracket, align the gypsum hollow strip 20 with the end of the corner bracket with the hole.

[0045] S4. Make holes in the gypsum hollow strip 20, and then fix the gypsum hollow strip 20 to the corner bracket through the bolt 50 to complete the installation of the beam plaster base layer.

[0046] This utility model ensures the stability of the gypsum hollow strip 20 by fixing it with corner brackets and bolts 50, providing a solid foundation for subsequent plastering work. At the same time, it simplifies the construction steps, improves construction efficiency, and reduces construction difficulty. Furthermore, the precise positioning and spacing control of the corner brackets, as well as the full welding technology, ensure the construction quality.

[0047] A gap is reserved between the first corner bracket 300 and the second corner bracket 40. The advantages of this design are: 1. It provides sufficient space, making it easier to align and fix the corner brackets during installation, especially when precise positioning is required; 2. During manufacturing and installation, there may be some dimensional errors, and the gap can accommodate these errors, ensuring correct installation of the corner brackets, even with slight deviations in material dimensions; 3. In the event of earthquakes or other vibrations, the gap provides a degree of flexibility to the structure, helping to absorb and disperse vibration energy and improve the structure's seismic performance; 4. In the manufacturing process, perfectly precise fit is often difficult to achieve, and the gap can reduce the precision requirements of the manufacturing process, thereby reducing manufacturing difficulty and cost.

[0048] In summary, this gap can bring many benefits. Furthermore, this gap is also to facilitate the insertion of positioning block 302 and plug-in block 402, thereby facilitating the connection of the two corner brackets.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
