Description

Technical Field

[0001] This utility model relates to a building foundation, specifically a general building foundation structure consisting of a pile pier and an assembled integral window frame, belonging to the field of construction. Background Technology

[0002] With the high-quality development of the social economy and the continuous improvement of people's living standards, many people are choosing to build their own new houses, especially in rural areas where farmers are building more and more self-built houses. However, due to limitations in construction technology and funding, self-built houses often experience structural cracks and wall tilting after a period of use. Furthermore, self-built houses have poor durability and are greatly affected by geological conditions, surface drainage, and climate. In particular, their earthquake resistance and structural strength are worrying, especially when facing natural disasters. Summary of the Invention

[0003] To address the issues of low structural strength, poor overall integrity, and non-standard construction processes in self-built houses due to limitations in construction technology and costs, a general-purpose building foundation structure consisting of pile piers and prefabricated integrated window frame was designed. This structure employs a modular design, allowing for on-site assembly of modular units to construct the building foundation, thus saving construction costs and improving the quality of self-built building foundations. It features clear stress distribution and easy construction.

[0004] The technical solution of this utility model is as follows:

[0005] A general building foundation structure consisting of pile piers and prefabricated integral window frame, including pile piers, column capstones, foundation connecting beams, partition wall beams, and drainage slabs;

[0007] When in use, holes are first drilled on the building ground by machinery or manual labor to form several foundation pile holes. Then, concrete is poured on site to form piles, which form the lower supporting structural unit of the column capstone or foundation connecting beam.

[0008] Based on the soil conditions of the construction site, the length, diameter, and end shape of the pile piers are designed, and the number of pile piers and the distribution of pile pier holes are selected. For building structures to be built on cultivated soil or miscellaneous fill soil, the bottom of the pile pier holes is explored during drilling so that the load of the superstructure can be transferred to the bearing layer of the old soil. This can solve the problem of uneven settlement of the building structure caused by the decrease in the bearing capacity of the foundation soil after rainwater soaking, which can lead to quality problems such as cracking and tilting of the building walls. At the same time, it can reduce the amount of excavation and filling soil required for the construction of the foundation trench, and directly fall to the bearing layer.

The upper and lower parts of the mortise and tenon groove are respectively provided with vertical bolt holes for installing bolts; the mortise and tenon groove is connected to the horizontal tongue and groove groove of the connecting beam; after the tenon of the foundation connecting beam is inserted into the mortise and groove groove of the connecting end, the bolt is inserted and tightened. After tightening, grout is poured into the tongue and groove joint, and then carbon fiber reinforcement is used to bond and seal the tongue and groove joint around the joint.

[0013] Furthermore, the number of connecting ends is 2-10; the column capstone is divided into two-port column capstone, three-port column capstone, four-port column capstone and five-port column capstone, depending on the number of connecting ends, and is selected according to the specific construction plan.

[0014] The foundation connecting beam is used to construct the foundation frame of the building; the base connecting beam is a "straight" precast reinforced concrete beam; the foundation connecting beam is divided into two types: external connecting beam and internal connecting beam.

[0015] The external connecting beam is used for installing lightweight exterior wall panels or as the foundation for building exterior walls. Both ends of the external connecting beam are tenons for connecting to the mortises on the column capstone.

The partition beam has a double row of through-hole fixing holes, which correspond to the double row of reserved holes on the inner connecting beam. The partition beam is assembled on the upper part of the inner connecting beam according to the interior layout and is connected by bidirectional rebar grouting through its respective reserved holes.

[0018] The drainage slab is used for outdoor drainage around the exterior walls of the proposed building; the drainage slab is a precast reinforced concrete drainage slab; the drainage slab has a right-angled trapezoidal structure; the front part of the drainage slab has a right-angled triangular slope structure; the drainage slab is installed on the top of the pile pier located at the exterior wall position; the surface of the drainage slab is coated with a waterproof and moisture-proof layer to prevent efflorescence at the wall base.

[0048] The specific method of using this utility model is as follows:

[0049] Step 1: Design of the prefabricated foundation system. Based on the building plan and the layout of the above-ground walls and columns, refine the design of the foundation system. Prioritize the design of the foundation connecting beams and column capstones. Then, arrange pile piers at the junctions of the column capstones and connecting beams or at the lower part of the mid-span of the connecting beams with large spans, forming a "honeycomb window-like" reinforced concrete prefabricated foundation plan window frame system assembly drawing;

[0050] Step 2: Foundation measurement and positioning and pile hole drilling. The positioning axis of the "window frame" foundation piles is measured on the ground of the proposed building site. At the "pile" location, the soil is excavated using rotary drilling machinery or manually (when the bearing layer is shallow). The old soil bearing layer must be seen at the bottom of each foundation pile hole.

[0051] The third step involves pouring concrete for the foundation piles on-site. The piles are inserted into the foundation holes to form support units. Column capstones or foundation beams with large spans are installed on the piles. The column capstones are fixed to the piles with reinforcing bars, and then joint grout is poured in for reinforcement. Adjacent column capstones are connected with connecting beams. After the tenon of the connecting beam is inserted into the mortise of the column capstone, bolts are inserted and tightened. After tightening, grout is poured into the tongue and groove joints. Then, carbon fiber reinforced strips are used to bond and seal the tongue and groove joints around the perimeter. After installation, a window-frame foundation structure is formed.

[0052] The fourth step is to install a drainage slab on the exposed pile platform outside the connecting beam located on the outer wall; install a frame column on the column capstone; and install a partition beam on the connecting beam. During installation, adjust the position of the partition beam according to the distribution of partition walls in the specific building unit to complete the installation of the partition beam.
