[0002] With the rapid development of global building market, UPVC (unplasticized polyvinyl chloride) fast house system gradually attracts attention due to its lightness, corrosion resistance, quick installation and other advantages.
[0003] The foundation design of fabricated UPVC house is the key link to ensure the stability, durability and wind resistance of the house. However, UPVC fast house system also has some disadvantages and deficiencies, such as low strength, poor fireproof performance, poor environmental protection and high price. Especially, combined with the characteristics of this material, the foundation design needs to be adapted to local conditions and different construction schemes need to be adopted according to different geographical environment and construction conditions.
[0004] In the conventional geological solid and stable plain area, it is easy to build various concrete houses, but in the coastal area, or mountainous area, or sandy island area, it is difficult to use the traditional concrete foundation in the complex environment of sandy soil, soft geology and high humidity, making it more difficult to build fixed houses. For example, in the coastal area, we often see single or double-story buildings of wooden structure, but this material determines that the service life of such houses is very short and cannot resist geological disasters such as typhoon and earthquake, and such building hardness is also difficult to seal, and cannot be modernized indoor design.
[0005] At present, it is difficult to solve the problem of economically suitable and well-fixed building foundation.
[0006] Therefore, we propose a UPVC ground keel laying structure under complex geological conditions to solve the above problems, so that under such complex geological conditions, modern buildings with strong hardness and decades of service life can also be constructed by laying ground keel.

By setting the cross section of the U-shaped ground batten 5 as U-shaped, the UPVC plate 7 can be conveniently installed.
[0027] Further, referring toFigure 1 And Figure 2 The connecting bolts 4 pass through the base steel 3 and the galvanized U-shaped floor joist 5 respectively, and the base steel 3 and the galvanized U-shaped floor joist 5 are firmly fixed. And the connecting bolts 4 are installed in multiple groups at equal distances in the base steel 3 and the galvanized U-shaped floor joist 5, and the galvanized U-shaped floor joist 5 can be installed in position by the connecting bolts 4 passing through the base steel 3 and the galvanized U-shaped floor joist 5.
[0028] Further, referring to Figure 1 And Figure 2 The mounting screws 6 are inserted into the UPVC plate 7 through the galvanized U-shaped floor joist 5, and the mounting screws 6 are provided in multiple groups on the side surface of the galvanized U-shaped floor joist 5, so that the UPVC plate 7 can be conveniently installed by the mounting screws 6 being inserted into the UPVC plate 7 through the galvanized U-shaped floor joist 5.
[0029] Further, referring to Figure 1 And Figure 2 The plate corner 8 is provided as a rectangular hole or a square hole (depending on the thickness of the two UPVC plates). The inner wall of the plate corner 8 is fixed with a rectangular steel pipe frame, and the rectangular steel pipe frame is welded with the spiral steel pipe pile 2 to ensure the firm connection of the house and the foundation, and further improve the stability of the overall structure.
[0030] The rectangular steel pipe frame fixed on the inner wall of the plate corner 8 can increase the strength of the plate corner 8 and avoid damage and deformation caused by collision.
[0031] Further, referring to Figure 1 And Figure 2 The base steel 3 and the galvanized U-shaped floor joist 5 are filled with polyurethane foam and rubber pads, and the polyurethane foam and rubber pads arranged between the base steel 3 and the galvanized U-shaped floor joist 5 can increase the installation stability of the galvanized U-shaped floor joist 5 and also play a role in shock absorption and protection.
[0032] In this way, a stable floor joist structure can be built in a humid, soft and poor soil environment. The structure disclosed in the utility model can bear a 2-3 story height of the fabricated building.
[0033] In the utility model, in order to adapt to the complex environment of sandy soil, soft geology and high humidity, the multiple main body reinforcing structures of the steel framework material are coupled and inserted to ensure the stability of the foundation, so as to match the material structure characteristics of the UPVC (unplasticized polyvinyl chloride) fast-assembly house produced by the market main body, including:
[0034] 1. Steel framework is used for installation at key positions of the UPVC fast-assembly house, such as the floor joist, roof truss and wall corner, so that the steel framework can significantly enhance the rigidity and stability of the overall structure and improve the wind resistance and pressure resistance of the house.
[0035] 2. Steel skeleton and UPVC plate are connected through bolts or buckles, ensuring firm connection and convenient disassembly.
[0036] Therefore, the ground beam laying structure designed by the utility model can also be used in occasions that need to be frequently disassembled and reassembled, for example, houses used by nomadic people in grasslands. The assembled UPVC house is superior to common folding box house type mobile houses in sound insulation, privacy and thermal insulation, and the assembled UPVC house with a stable foundation has greatly improved seismic resistance and a service life several times longer than that of common mobile houses.
[0037] The utility model installs the spiral steel pipe pile 2 as a pre-embedded part in the concrete foundation, and is welded with the inner wall fixed rectangular steel pipe frame of the plate corner 8, ensuring firm connection of the house and the foundation and further improving the stability of the overall structure.
[0038] The design of the spiral steel pipe pile 2 (pre-embedded part) should consider the tensile and shear capacity to resist external forces such as strong winds and earthquakes.
[0039] Working principle: during construction of the utility model, the soil quality involved in the foundation is first solidified, and the curing agent is uniformly dispersed into the soil, and the tiny particles can penetrate into the pores between the soil particles, so that the arrangement of the soil particles is more compact. With the advancement of the solidification process, the soil gradually changes from a loose particle state to a plate structure with integrity, which significantly enhances the soil's ability to withstand external loads, thereby improving its bearing capacity.
[0040] After the solidified soil 1 is formed, according to the structure of Figure 1 、 Figure 2 , the spiral steel pipe pile 2 is inserted into the inside of the solidified soil 1. The foundation steel 3 is welded above the spiral steel pipe pile 2, and the U-shaped ground beam 5 is installed above the foundation steel 3 through the connecting bolts 4.
[0041] The galvanized U-shaped ground beam 5 is installed above the foundation steel 3 through the connecting bolts 4, and the UPVC plate 7 is placed in the galvanized U-shaped ground beam 5. The UPVC plate 7 is installed by passing the mounting screws 6 through the galvanized U-shaped ground beam 5 and the UPVC plate 7, so that the foundation steel 3 can drive the spiral steel pipe pile 2 to pass through the solidified soil 1, and the foundation steel 3 and the UPVC plate 7 can be installed.
[0042] Thus, the UPVC ground dragon bone laying structure can be applied in sandy soil, soft geology, high humidity and other complex soil environments according to the site, including installation on the concrete foundation structure in the plain area, installation on the small pile foundation in the mountain, coastal and island areas. Cooperating with the main material of the assembled UPVC house, the structure can quickly build an anti-seismic and durable, fully-closed modern building, and the service life can reach 20 to 30 years.
[0043] The above is the whole working principle of the utility model.
[0044] In the utility model, the installation mode, connection mode or setting mode of all the components are common mechanical modes, and the specific structure, model and coefficient index of all the components are self-contained technologies, as long as the beneficial effects can be achieved, and therefore, no more description is made.
