Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically a modular new rural villa combination structure. Background Technology

[0002] Modular foundations for new rural villas represent a modern foundation construction solution designed for rapid, stable, and environmentally friendly infrastructure development through the assembly of prefabricated modules. The core of this approach lies in breaking down traditional foundation structures into standardized prefabricated modules, including foundation slabs and column bases, which are then assembled using connectors. This simplifies the construction process, shortens the construction period, and improves construction quality. In practice, the specifications and layout of the foundation modules are first determined based on the design drawings, and then they are prefabricated in the factory and transported to the site. Before construction, foundation preparation is carried out to ensure that the construction area is flat and solid. During installation, prefabricated modules are placed one by one into the predetermined positions using cranes and other machinery to ensure precise alignment. They are then spliced ​​and fixed with connectors to ensure the stability of the overall structure. The entire process emphasizes horizontal and vertical alignment to ensure the reliability of the foundation. However, at present, after the modular foundation is assembled on site, the concrete slab is a single-layer foundation structure. The load-bearing capacity of a single-layer concrete slab is limited, especially when facing heavy or uneven loads, which can easily lead to local deformation or cracking. Although prefabricated modules and overall assembly can provide a certain degree of rigidity, under some special geological conditions or with large building loads, the lack of buffering and dispersion effects of multi-layer structures means that the foundation may be affected by environmental erosion, freeze-thaw cycles, and other factors during long-term use, leading to crack expansion, weakening of strength, and affecting the overall service life. Utility Model Content

[0003] The purpose of this utility model is to provide a modular new rural villa combination structure, which is equipped with a double-layer foundation frame that can be connected front to back and left to right. The double-layer foundation frame is equipped with a lower concrete slab and an upper concrete slab to form a double-layer structure, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular new rural villa combination structure, including a double-layer foundation frame, a cavity set inside the double-layer foundation frame, a lower concrete slab installed inside the cavity, and an upper concrete slab installed on the upper surface of the lower concrete slab. A left connecting plate and a right connecting plate are welded and fixed to the left and right sides of the top of the double-layer foundation frame, respectively. The left and right connecting plates are used to connect two adjacent double-layer foundation frames in the X-axis direction. A rectangular protrusion is integrally formed on one outer wall of the upper concrete slab, and a rectangular cavity is formed on the other outer wall of the upper concrete slab. The rectangular protrusion and the rectangular cavity are used to connect two adjacent upper concrete slabs in the Y-axis direction.

[0005] Preferably, the left docking plate has two symmetrical lugs with through holes integrally formed on the outer wall of the side away from the double-layer foundation frame, and the right docking plate has internal threaded holes on both the front and rear outer walls.

[0006] Preferably, a number of U-shaped longitudinal beams are welded and fixed at equal intervals along the X-axis at the bottom of the double-layer foundation frame. The double-layer foundation frame is composed of an upper loop frame and a lower loop frame, with the upper loop frame welded and fixed to the upper surface of the lower loop frame.

[0007] Preferably, column-shaped support structures are installed at the left and right outer corners of the double-layer foundation frame.

[0008] Preferably, the column support structure includes a frame fixed at the left and right outer corners of the double-layer foundation frame, a hollow plate fixed on one side of the outer wall of the frame, and a steel column installed inside the hollow plate, with a cutting groove provided on one side of the outer wall of the steel column.

[0009] Preferably, the upper surface of the lower concrete slab is provided with a rectangular recess, and the lower surface of the upper concrete slab is integrally formed with a rectangular rib for docking with the rectangular recess.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This modular new rural villa combination structure, through the use of a double-layer foundation frame, a cavity, a lower concrete slab, an upper concrete slab, and left and right connecting plates, adopts a double-layer foundation frame that can be connected front to back and side to side. The upper and lower concrete slabs are installed inside to form a double-layer structure, thereby improving the foundation's bearing capacity and seismic performance, enhancing the structure's stability and durability, and providing a solid guarantee for the safe operation of the building. The double-layer foundation frame, through the combined action of the upper and lower layers, disperses the load pressure, enhances the foundation's compressive and bending resistance, and the double-layer structure design, through mutual support and reinforcement between layers, effectively reduces foundation deformation and cracking, improving the overall seismic resistance to resist ground vibration and ensure the safety of the superstructure. Secondly, the modular splicing method enables rapid assembly, reducing construction time and difficulty, and providing more space and flexibility. The structural layers can be adjusted or added as needed to meet ever-changing usage requirements. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Example 1, by Figures 1 to 4 As shown, this utility model includes a double-layer foundation frame 1, a cavity 7 set inside the double-layer foundation frame 1, a lower concrete slab 2 installed inside the cavity 7, and an upper concrete slab 3 installed on the upper surface of the lower concrete slab 2. The cavity 7 provides sufficient chamber space for the placement of the lower concrete slab 2.

[0020] Left connecting plate 6 and right connecting plate 8 are welded and fixed to the left and right sides of the top of the double-layer foundation frame 1, respectively. The left connecting plate 6 and right connecting plate 8 are used to connect two adjacent double-layer foundation frames 1 in the X-axis direction. A rectangular protrusion is integrally formed on one side of the outer wall of the upper concrete slab 3, and a rectangular cavity is opened on the other side of the outer wall of the upper concrete slab 3. The rectangular protrusion and the rectangular cavity are used to connect two adjacent upper concrete slabs 3 in the Y-axis direction.

[0021] On the outer wall of the left connecting plate 6 away from the double-layer foundation frame 1, there are two symmetrical lugs 601 integrally formed with through round holes. The front and rear outer walls of the right connecting plate 8 are provided with internal threaded holes. When two adjacent double-layer foundation frames 1 are connected left and right, the two lugs 601 on the outer wall of the left connecting plate 6 are located on the front and rear outer walls of the right connecting plate 8. After the right connecting plate 8 and the left connecting plate 6 are connected, the left connecting plate 6 and the right connecting plate 8 can be fastened with bolts.

[0022] The upper surface of the lower concrete slab 2 is provided with a rectangular recessed part, and the lower surface of the upper concrete slab 3 is integrally formed with a rectangular rib for docking with the rectangular recessed part. The connection stability of the lower concrete slab 2 and the upper concrete slab 3 is improved by the rectangular rib and the rectangular recessed part.

[0023] After the double-layer foundation frame 1, lower concrete slab 2, and upper concrete slab 3 are assembled and the frames are joined front and back, two rectangular protrusions on the outer wall of one upper concrete slab 3 are inserted into a rectangular cavity on the outer wall of the other upper concrete slab 3, and the upper concrete slab 3 is used to further connect the frames in the front and back direction.

[0024] Example 2, based on Example 1, is... Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, several U-shaped longitudinal beams 5 are welded and fixed at equal intervals along the X-axis at the bottom of the double-layer foundation frame 1. The double-layer foundation frame 1 consists of an upper loop frame 101 and a lower loop frame 102. The upper loop frame 101 is welded and fixed to the upper surface of the lower loop frame 102. The double-layer design of the double-layer foundation frame 1 can effectively distribute the load pressure of the foundation, reduce the risk of deformation or cracking caused by local overload, and also provide greater rigidity, which helps to resist uneven settlement of the foundation or seismic action, and ensure the stability of the superstructure.

[0025] The left and right outer corners of the double-layer foundation frame 1 are each equipped with a column-shaped support structure 4. The column-shaped support structure 4 includes a frame 403 fixed at the left and right outer corners of the double-layer foundation frame 1, a hollow plate 401 fixed on one side of the outer wall of the frame 403, and a steel column 402 installed inside the hollow plate 401. A cutting groove 4021 is provided on one side of the outer wall of the steel column 402. The column-shaped support structures 4 at the left and right corners of the double-layer foundation frame 1 support the double-layer foundation frame 1, so that the double-layer foundation frame 1 is stably erected in the foundation pit. The steel column 402 is concentrically inserted into the hollow plate 401, and the hollow plate 401 and the steel column 402 are connected by a flange.

[0026] In this embodiment, the workers first thoroughly clean and measure the construction site to ensure the foundation meets the design requirements. If necessary, the foundation should be compacted and leveled to ensure good bearing capacity and stability. Based on this, all prefabricated components, including the double-layer foundation frame 1, lower concrete slab 2, and upper concrete slab 3, are pre-stacked at a designated location on the construction site for easy access later. The workers place the prefabricated double-layer foundation frame 1 in the foundation pit according to the design position, ensuring its accuracy. When connecting two adjacent double-layer foundation frames 1, the left connecting plate 6 and right connecting plate 8 at opposite ends of the two adjacent double-layer foundation frames 1 are connected and bolted together. During this process, the workers should ensure that the connecting surfaces of the two double-layer foundation frames 1 are flat and tightly fitted. A level or laser level can be used during installation. Calibration is performed to ensure the horizontal and vertical alignment of the double-layer foundation frame 1, preventing deviations in subsequent connections. After the double-layer foundation frame 1 is stabilized, the lower concrete slab 2 is inserted into the interior of the double-layer foundation frame 1, ensuring a tight fit between the lower concrete slab 2 and the connection surface of the double-layer foundation frame 1, avoiding gaps or deviations. After the lower concrete slab 2 is fully installed in the cavity 7, the upper concrete slab 3 is placed on top of the lower concrete slab 2, ensuring a tight fit between the connection surfaces of the lower concrete slab 2 and the upper concrete slab 3, ensuring a firm and secure connection. Throughout the installation process, workers need to continuously check to ensure that the connections of each part are tight and level. After the assembly of all components is completed, workers conduct a comprehensive inspection of the overall structure, checking the tightness of the connectors to confirm there is no looseness or deviation, and checking the flatness and alignment of the concrete slabs to ensure the integrity and safety of the structure.
