Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more particularly to a building foundation connection structure. Background Art

[0002] The foundation refers to the underground extension of a building's walls or columns, which rest on the foundation. The design and testing of foundations is a crucial part of the work of construction engineers. The portion of a building buried below the ground is called the foundation. The soil layer that bears the load transmitted by the foundation is called the subgrade. The first layer of soil below the bottom of the foundation is called the bearing stratum, and the soil layer below it is called the underlying stratum. With the development of the times, the number of construction sites for building houses has increased. Generally, when building a house, the foundation structure must first be erected on the ground to facilitate subsequent construction and provide greater stability during construction. However, during the foundation construction process, due to the poor shock absorption of typical foundation structures and the simple and unstable connection structure of the foundation, subsequent house construction often has a certain impact.

[0003] An existing patent (publication number: CN213204186U) discloses a foundation connection structure comprising a foundation body with a mounting groove defined on its upper surface. A column is mounted within the groove. A bearing block is fixedly mounted on the sidewall of the column. A first fixing assembly is provided on the sidewall of the column to secure the bearing block. A mounting block is fixedly mounted on the bearing block, with its lower surface abutting the upper surface of the bearing block. A second fixing assembly is provided on the sidewall of the column to secure the mounting block. Adjacent columns are supported by support rods, the ends of which are fixedly connected to the sidewalls of the columns away from the mounting block. This application aims to increase the stability of the column body in supporting a building. During the development of this invention, the inventors discovered the following problems with the prior art: 1. The foundation structure has poor shock absorption, resulting in cracking and unusability of the building walls after completion; 2. Most foundation connections are simple and unstable, leading to low stability and poor quality of subsequent building construction. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to enhance the bearing capacity of the foundation through reasonable material selection, flexible design scheme and optimized construction method, while also improving construction efficiency, saving costs and enhancing seismic performance, and having strong market competitiveness.

[0005] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0006] A building foundation connection structure, wherein the ground beam is cast by steel bars, and the foundation is a steel bar structure therein, including: an upper chord beam, diagonal braces, web members, a lower chord beam, and vertical beams perpendicular to the ground. The lower chord beam, web members, diagonal braces and upper chord beam form a steel frame structure, and the cross-section of the steel frame structure is a trapezoidal structure; the bottom of the vertical beam is connected to the lower chord beam, passes through the upper chord beam upward, and is fixed by binding wire or welding.

[0007] In a specific embodiment, the cross-section of the steel frame structure is an isosceles trapezoid, and the length of the web member is one third to one half of the length of the cross-section of the upper chord beam.

[0008] In a specific embodiment, the horizontal cross-section of the vertical beam includes but is not limited to a rectangle and a circle.

[0009] In a specific embodiment, concrete is filled between the upper chord and the lower chord, concrete is poured into the vertical beam, and the vertical beam and the upper chord are connected into a whole by concrete.

[0010] In a specific embodiment, the upper chord beam and the lower chord beam are formed by tying or welding steel bars.

[0011] It can be seen from the above technical solution that compared with the prior art, the present invention has the following beneficial effects:

[0012] The beneficial effects of this new composite building formwork are reflected in its structure, material selection, temperature control design, etc., and it has the following significant advantages:

[0013] 1. Improved structural stability and bearing capacity: The steel frame of this structure is composed of upper and lower chord beams, diagonal braces, and web members, forming a steel frame structure with strong stability and deformation resistance. The trapezoidal cross-section of the steel frame structure can effectively share the vertical and horizontal loads of the foundation, thereby enhancing the overall bearing capacity and structural stability of the foundation and preventing foundation settlement or deformation caused by uneven load distribution.

[0014] 2. Optimizing Space and Material Usage: The use of reinforced cast-in-place ground beams in conjunction with a steel frame structure optimizes material efficiency. The steel frame's isosceles trapezoidal cross-section ensures excellent load-bearing capacity while minimizing unnecessary material waste. The web member length is set to one-third to one-half the cross-sectional length of the upper chord, achieving a good balance between the structure's load-bearing capacity and material economy.

[0015] 3. Construction Convenience and Flexibility: Vertical beams are fixed between the upper and lower chords using binding wires or welding, simplifying construction and reducing complex process steps. Furthermore, the optional cross-sections of the vertical beams (rectangular, polygonal, circular, etc.) provide design flexibility, enabling customization based on actual conditions and needs to meet the structural requirements of different construction projects.

[0016] 4. Save construction time and cost: Concrete is filled between the upper chord and the lower chord, and concrete is poured into the vertical beam. The vertical beam and the upper chord are connected into a whole through concrete; this helps to improve the integrity and seismic resistance of the connection part.

[0017] 5. Enhanced seismic performance: The structure is designed with full consideration for earthquake resistance. The steel frame has excellent elasticity and can effectively absorb the energy caused by earthquakes, reducing the impact of vibrations on the building. The combination of steel frame and concrete structure not only ensures overall strength but also improves seismic performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] This embodiment provides an innovative building foundation connection structure, designed to improve foundation bearing capacity, structural stability, and construction efficiency while reducing costs through scientific and rational structural design and material selection. This structure, comprising reinforced concrete ground beams and a steel frame, is ingeniously designed to meet the demands of modern buildings for high-performance foundation systems.

[0025] The building's foundation connection structure consists of a reinforced concrete ground beam and a steel frame. The steel frame includes an upper chord 1, a lower chord 5, web members 4, diagonal braces 3, and vertical beams 2. The upper chord 1 and lower chord 5 are arranged in parallel, with web members 4 and diagonal braces 3 bearing lateral and diagonal loads, respectively, forming a strong and stable frame. Vertical beams 2, perpendicular to the ground and located between the upper chord 1 and lower chord 5, provide critical wall support and ensure overall structural stability.

[0026] The steel frame's cross-section is designed as an isosceles trapezoid, which provides sufficient strength while optimizing material efficiency. The web member (4) is designed to be between one-third and one-half the cross-sectional length of the upper chord (1). This optimal size ratio ensures sufficient load-bearing capacity while avoiding excessive material use, achieving a balance between cost-effectiveness and safety.

[0027] The construction process of this foundation connection structure is simple and efficient. First, the main components of the steel frame structure and ground beam (upper chord 1, lower chord 5, web members 4, diagonal braces 3, and vertical beams 2) can be prefabricated in the factory, requiring only on-site assembly, significantly shortening the construction period and reducing the difficulty of on-site construction. Furthermore, the vertical beams 2 are secured to the lower chord 5 and upper chord 1 via welding or wire tying, ensuring a stable connection and reducing uncertainty during on-site construction.

[0028] The space between the upper chord beam 1 and the lower chord beam 5 is filled with concrete, and the vertical beams are connected to form a whole by pouring concrete. This design not only enhances the bearing capacity of the structure, but also enables the construction to be completed quickly, reducing labor and material costs.

[0029] And has the following advantages:

[0030] Improve foundation bearing capacity and stability

[0031] This structure effectively enhances the foundation's bearing capacity through the rationally designed combination of a steel frame and reinforced concrete ground beams. The steel frame's isosceles trapezoidal cross-section and the optimal proportions of its web members evenly distribute the load, reducing stress concentration and effectively improving foundation stability. This design adapts to varying soil conditions, providing sufficient support and preventing settlement or uneven deformation.

[0032] Flexible adaptation to different foundation conditions

[0033] The cross-sectional form of the vertical beams (rectangular, polygonal or circular) offers great flexibility and can be customized to meet the needs of different construction projects. This allows the structure to be widely used in various foundation conditions, especially in complex geological environments that require improved bearing capacity and stability.

[0034] Enhanced earthquake resistance

[0035] The steel frame's inherent elasticity and toughness effectively disperse energy during earthquakes, reducing the impact of vibrations on the structure. Concrete connections between the vertical beams and the upper and lower chords further enhance the overall structure's seismic performance, making it suitable for construction projects in seismically active areas.

[0036] Save materials and reduce costs

[0037] The isosceles trapezoidal steel frame design and rationally arranged web members ensure the structure's load-bearing capacity while optimizing material usage and avoiding unnecessary waste. The combination of reinforced concrete and steel frames reduces the material and construction costs associated with pure concrete structures. Furthermore, the concrete infill design simplifies the construction process, reduces labor costs, and improves efficiency.

[0038] Construction convenience and efficiency

[0039] Because the steel frame and ground beams can be prefabricated in a factory, on-site workload is significantly reduced, shortening the construction period. The assembly of the steel frame and ground beams also simplifies construction steps and reduces on-site complexity. The concrete filling method allows for rapid completion of the entire structure, minimizing the risk of delays due to weather conditions, labor shortages, and other factors.

[0040] Enhanced durability and maintainability

[0041] The reinforced concrete and steel used in this structure are both highly durable materials that can effectively resist environmental corrosion and extend the building's service life. Furthermore, the vertical beams, upper chords, and lower chords are connected by poured concrete, ensuring the overall stability of the structure and facilitating subsequent maintenance.

[0042] This structure is widely applicable to various construction projects, especially those with high requirements for foundation bearing capacity and stability, such as high-rise buildings, industrial plants, bridges, and infrastructure projects. Due to its flexible design, simple construction, and high cost-effectiveness, it is suitable for a variety of geological conditions and foundation environments and has broad market application prospects.

[0043] This embodiment optimizes the bearing capacity and stability of the building foundation through the scientific and rational combination of a steel frame structure and reinforced concrete ground beams, while achieving high efficiency and cost-effectiveness during construction. The structural flexibility enables it to adapt to varying foundation conditions and meet the needs of various construction projects. Overall, this structure is highly practical and competitive, meeting the high-performance foundation system requirements of modern buildings.

Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.
