Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to foundation column structures with steel structures for civil engineering. Background Technology

[0002] In civil engineering, steel columns are often pre-embedded in concrete foundation columns. This is a common building structure design method that can improve the building's load-bearing capacity, seismic performance, and stability.

[0003] A search revealed Chinese patent CN220954205U, which discloses a steel structure foundation column structure for civil engineering projects. The structure includes a base, with bolt holes symmetrically arranged on the upper sidewalls of the base: bolt hole 1, bolt hole 2, bolt hole 3, bolt hole 4, bolt hole 5, and bolt hole 6. The advantages are: this patent features parallel steel plates 1 and 2. Ribs 1 and 2, perpendicular to each other, are fixedly connected to the left and right sidewalls of steel plate 1, respectively. Ribs 3 and 4, also perpendicular to steel plate 2, are fixedly connected to the left and right sidewalls of steel plate 2, respectively. Ribs 1 and 2 are rotationally symmetrical about steel plate 1, and ribs 3 and 4 are also rotationally symmetrical about steel plate 2. When the foundation column is subjected to an external torque, ribs 1 and 2 generate resistance and a counter-torque on steel plate 1, while ribs 3 and 4 also generate a counter-torque on steel plate 2. Together, they resist torsional deformation, enhancing the torsional resistance of the steel structure foundation column.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] The aforementioned patents use too much steel, resulting in excessively high construction material costs. They also do not employ pre-embedded concrete column connectors, leading to a complex and unsafe construction process. The columns cannot be securely injected into the foundation, resulting in poor contact with the ground and poor building stability, thus presenting certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a foundation column structure with steel structure for civil engineering projects, which increases the installation depth and improves the stability of the building.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a foundation column structure with steel structure for civil engineering, including a foundation pit and multiple reinforcing bars, a base plate is provided on the surface of the foundation pit, a slot is opened inside the base plate, multiple round holes are opened on the outer peripheral wall of the base plate, a steel column is fixedly installed on the foundation pit, the steel column is snapped into the slot, a connecting plate is fixedly installed at the bottom of the steel column together with the base plate, and also includes cast-in-place pile rods;

[0008] The cast-in-place pile rod comprises several round pipes fixedly connected to the top of the foundation pit through round holes.

[0009] Preferably, a steel pipe is fixedly installed at the bottom of the circular tube, a pointed end is fixedly installed at the bottom of the steel pipe, multiple perforations are opened on the surface of the steel pipe, and multiple propellers are fixedly installed on the outer peripheral wall of the steel pipe.

[0010] Preferably, a limiting ring is fixedly installed at the top of the circular tube, a thick steel bar is fixedly installed inside the steel tube, and multiple connecting cylinders are fixedly installed on the surface of the limiting ring.

[0011] Preferably, the bottom ends of the plurality of steel bars are respectively inserted into the connecting cylinder, and the surface of the foundation pit and the exterior of the steel column are jointly cast with concrete blocks.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model improves the bearing capacity and seismic performance of the foundation column structure by installing steel round pipes and thick steel bars. It can effectively fix the base plate, which serves as a steel column connector, in the foundation pit. Moreover, the cast-in-place pile rods inserted into the soil below the foundation pit relatively increase the installation depth of the entire foundation column and the contact area with the soil below.

[0014] Secondly, under the support of cast-in-place piles, this utility model can relatively reduce the depth of the foundation pit, and the steel column is installed inside the concrete column. The steel column and the concrete column have excellent stress connection, which can effectively enhance the seismic performance of the building structure and improve the stability of the building while bearing the load.

[0015] This solution addresses the problems of excessive steel usage leading to high construction material costs, the lack of concrete-embedded column connectors resulting in complex and unsafe construction processes, columns that cannot be securely embedded in the foundation, poor ground contact, and overall building stability.

[0023] 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.

[0024] This utility model provides an improved foundation column structure with steel structure for civil engineering projects. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a foundation column structure with steel structure for civil engineering includes a foundation pit 1 and multiple reinforcing bars 5. A base plate 2 is provided on the surface of the foundation pit 1. The base plate 2 has a slot 202 inside and multiple round holes 201 on the outer peripheral wall of the base plate 2. A steel column 11 is fixedly installed on the foundation pit 1. The steel column 11 is snapped into the slot 202. The bottom of the steel column 11 and the base plate 2 are fixedly installed with a connecting plate 4, which relatively increases the installation depth of the entire foundation column and the contact area with the soil below, thereby making the constructed foundation column more stable. It also includes cast-in-place pile rods 3.

[0026] The cast-in-place pile 3 includes several round pipes 308 that are fixedly connected to the top of the foundation pit 1 through round holes 201. Under the support of the cast-in-place pile 3, the depth of the foundation pit 1 can be relatively reduced.

[0027] Furthermore, a steel pipe 301 is fixedly installed at the bottom of the circular pipe 308, and a pointed end 302 is fixedly installed at the bottom end of the steel pipe 301. Multiple perforations 304 are opened on the surface of the steel pipe 301, and multiple propellers 303 are fixedly installed on the outer peripheral wall of the steel pipe 301. This increases the installation depth, strengthens the connection between the foundation and the soil, and improves the stability of the entire foundation.

[0028] Furthermore, a limiting ring 305 is fixedly installed on the top of the circular tube 308, a thick steel bar 306 is fixedly installed inside the steel tube 301, and multiple connecting cylinders 307 are fixedly installed on the surface of the limiting ring 305. While bearing the load, it can also effectively enhance the seismic performance of the building structure.

[0029] Furthermore, the bottom ends of multiple reinforcing bars 5 are respectively inserted into the connecting cylinder 307, and concrete blocks 6 are poured together on the surface of the foundation pit 1 and the exterior of the steel column 11, which effectively prevents the soil inside the foundation from collapsing and ensures the safety of the construction process.

[0030] The specific working method is as follows: First, an excavator is used in conjunction with personnel to excavate the foundation pit 1. The bottom surface and inner wall of the foundation pit 1 are compacted and coated with cement, which can effectively prevent the soil on the inner wall of the foundation pit 1 from collapsing. After the cement in the foundation pit 1 has completely solidified, the base plate 2 is fixedly installed on the inner bottom surface of the foundation pit 1 using cast-in-place piles 3. When the cast-in-place piles 3 are inserted into the soil below the foundation pit 1, holes are drilled in advance, and concrete is poured into the drilled holes, so that the cast-in-place piles 3 are surrounded by concrete. Moreover, after the foundation pit 1 is poured with concrete later, concrete will also flow into the cast-in-place piles 3, which will again surround the thick steel bars 306 in the cast-in-place piles 3, which can effectively prevent the soil from collapsing. First, the base plate 2 is fixedly installed in the foundation pit 1, and the cast-in-place pile rod 3 is inserted into the soil below the foundation pit 1. Next, after the concrete in the drilled hole has completely solidified, a crane is used to vertically lift the steel column 11 into the foundation pit 1, and workers work together to align the lower end of the steel column 11 with the slot 202 in the base plate 2. Then, the welder welds and fixes the part connecting the steel column 11 and the base plate 2, and multiple connecting plates 4 are used to increase the connection points between the steel column 11 and the base plate 2, so that the steel column 11 is stably fixed on the base plate 2. Then, multiple steel bars 5 are inserted into the connecting cylinder 307 on the cast-in-place pile rod 3 in sequence. Concrete is poured into the foundation pit 1 to form a concrete block 6.

[0031] 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.
