Description

Technical Field

[0001] This utility model relates to the field of steel pipe column foundation construction technology, specifically a modular prefabricated steel structure foundation for steel pipe columns. Background Technology

[0002] Currently, the foundations for cast-in-place concrete beam bridge construction in China are mainly reinforced concrete strip foundations or independent spread foundations. Because the concrete must reach a certain age before the next construction step can be carried out, the construction cycle of traditional reinforced concrete foundations is relatively long. At the same time, reinforced concrete foundations cannot be recycled and must be removed after construction, ultimately generating a lot of construction waste. Therefore, they are not only expensive to construct but also environmentally unfriendly and do not conform to the trend of green construction.

[0003] Based on this, this utility model proposes a modular prefabricated steel structure foundation with steel pipe columns. Utility Model Content

[0004] To address the aforementioned technical issues, this utility model proposes a modular prefabricated steel structure foundation with steel pipe columns. By adopting modular design and prefabricated construction, and through the flexible splicing and bolt connection of standard segments, rapid installation and disassembly are achieved, greatly shortening the construction cycle.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a modular prefabricated steel structure foundation with steel pipe columns, including a standard steel foundation segment, on which two stiffening plates are fixedly connected, and two adjacent stiffening plates are fixedly connected by connecting bolts. The standard steel foundation segment is provided with a reserved column foundation section, on which steel pipe columns are fixedly connected by flanges, and adjacent steel pipe columns are fixedly connected by flanges.

[0006] Preferably, a stiffening plate 2 is fixedly connected within the reserved section of the column foundation, and the stiffening plate 2 has multiple reserved bolt holes 1.

[0007] Preferably, a stiffening plate three is fixedly connected to the reserved section of the column foundation, and the stiffening plate three has multiple reserved bolt holes two.

[0008] Preferably, the steel structure foundation is constructed by splicing together different numbers of standard steel foundation segments to form an integral strip foundation or an independent spread foundation adapted to different bridge widths.

[0009] Preferably, the standard steel foundation segment 1 and all connecting components are made of weathering steel.

[0010] Compared with existing technologies, the significant advantages of this invention are:

[0011] Firstly, this utility model adopts modular design and prefabricated construction. Through the flexible splicing and bolt connection of standard segments, it realizes rapid installation and disassembly, which greatly shortens the construction cycle. Moreover, the overall structure can be reused, avoiding the construction waste generated by traditional concrete foundations and meeting the requirements of green and environmentally friendly construction.

[0012] Secondly, this utility model has excellent adaptability and durability. Its length, column spacing and foundation form can be flexibly adjusted according to the bridge width and foundation bearing capacity. At the same time, the design of multiple rows of bolt holes in the reserved section allows it to adapt to columns of different diameters. In addition, all components are made of weathering steel, which effectively improves the corrosion resistance and service life of the foundation and enhances its economy and reliability in complex environments.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved modular prefabricated steel structure foundation with steel pipe columns. The technical solution of this utility model is as follows:

[0022] like Figures 1-4As shown, a modular prefabricated steel structure foundation with steel pipe columns includes a standard steel foundation segment 1. Two stiffening plates 2 are fixedly connected to the standard steel foundation segment 1. The stiffening plates 2 are vertically set at both ends of the segment. During on-site assembly, multiple standard segments can be quickly and reliably spliced ​​by connecting bolts 3 penetrating and tightening the stiffening plates 2 of adjacent segments. This structural design allows the total length of the foundation and the spacing between columns to be flexibly and continuously adjusted according to the actual bridge width, which is the key to realizing its modular and prefabricated functions. The standard steel foundation segment 1 is provided with a column foundation reserved section 4. Steel pipe columns 5 are fixedly connected to the column foundation reserved section 4 through flanges 6. Adjacent steel pipe columns 5 are fixedly connected through flanges 6. By stacking different numbers of steel pipe columns 5, different support column heights can be accommodated.

[0023] Furthermore, such as Figure 4 As shown, a stiffening plate 2 7 is fixedly connected inside the reserved section 4 of the column foundation. Multiple reserved bolt holes 1 8 are opened on the stiffening plate 2 7. The position of the flange 6 is adjusted and fixed by using the reserved bolt holes 1 8 on the stiffening plate 2 7 to adapt to steel pipe columns 5 of different diameters.

[0024] Furthermore, such as Figure 4 As shown, a stiffening plate 3 9 is fixedly connected to the reserved section 4 of the column foundation. Multiple reserved bolt holes 2 10 are opened on the stiffening plate 3 9. The reserved section 4 of the column foundation is fixed to the standard section 1 of the steel foundation through the stiffening plate 3 9, the reserved bolt holes 2 10 and the threaded bolts.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the steel structure foundation is constructed by splicing together different numbers of standard steel foundation segments 1 to form an integral strip foundation or an independent enlarged foundation that can be adapted to different bridge widths. This enables rapid installation and dismantling, greatly shortens the construction cycle, and the overall structure can be reused.

[0026] Furthermore, such as Figures 1-4 As shown, all standard steel foundation segments 1 and connecting components such as stiffening plates, connecting bolts 3, and flanges 6 are preferably made of high-strength weather-resistant steel. This material selection not only gives the foundation excellent mechanical properties, but its inherent corrosion resistance can also significantly improve the service life and durability of the structure in harsh environments such as outdoor humidity, thereby increasing the number of times the entire foundation can be reused and enhancing its economic efficiency.

[0027] The specific working method is as follows: First, determine whether to use a strip foundation or an independent foundation based on the bridge width and the bearing capacity of the foundation, and calculate the number of standard steel foundation segments 1 required; then, assemble on site, and fasten the stiffening plates 2 of adjacent segments together with connecting bolts 3 to form an integral foundation structure; next, at the reserved section 4 of the column foundation, use the pre-reserved bolt holes 8 on the inner top stiffening plate 7 to adjust and fix the position of the flange 6 to accommodate steel pipe columns 5 of different diameters; finally, install each steel pipe column 5 onto the reserved section of the foundation through the flange 6, completing the construction of the entire reusable and adjustable modular steel structure foundation.

[0028] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
