[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a prefabricated truss house includes a floor slab 100 and a wall assembled from multiple prefabricated wall panels 200. The prefabricated wall panels 200 include a truss structure 1 and calcium silicate boards 2 attached to both sides of the truss structure. The truss structure 1 includes a rectangular frame 14 composed of an upper beam 11, a lower beam 12 and two frame columns 13. Multiple connecting rods 15 are provided in the rectangular frame. Each connecting rod is connected to the upper beam and the lower beam respectively. The multiple connecting rods are connected end to end in sequence so that two adjacent connecting rods are combined with the upper beam or the lower beam to form an isosceles triangle 16. The ends of the first and last connecting rods are connected to the apex angle 141 of the rectangular frame. Foamed concrete 3 is filled in the rectangular frame between the calcium silicate boards 2 attached to both sides of the truss structure.

[0032] In this embodiment, the floor slab 100 is a precast concrete floor slab or a precast steel structure floor slab, connected to the wall by bolts or welding, ensuring the stability and robustness of the overall structure. The truss structure 1 on the precast wall panel 200 adopts an isosceles triangle structure, which is rationally designed and not only enhances the load-bearing capacity of the wall but also improves its seismic performance. Meanwhile, the calcium silicate board 2, as the wall panel material, has advantages such as being lightweight, high-strength, fireproof, and moisture-proof, further enhancing the usability of the prefabricated truss house.

[0033] Multiple connecting rods 15 installed within the rectangular frame 14 connect end-to-end with the upper beam 11 and lower beam 12 to form an isosceles triangle 16. This structural design makes the truss structure more stable and effectively resists the impact of external forces. In addition, the installation of connecting rods 15 increases the overall stiffness of the truss structure and improves the lateral force resistance of the wall.

[0034] The foamed concrete 3 filling the rectangular frame between the calcium silicate boards 2 attached to both sides of the truss structure has good thermal insulation properties, which can effectively reduce indoor temperature fluctuations and improve the living comfort of prefabricated truss houses. At the same time, foamed concrete also has the advantages of being lightweight, high-strength, and sound-insulating, further enhancing the overall performance of prefabricated truss houses.

[0035] In this embodiment, connecting plates 131 are provided at both the top and bottom of the frame columns, and fixing holes 132 are provided on the connecting plates. The connection plates and fixing holes further enhance the connection strength between the frame columns. By connecting and fixing the connecting plates with fasteners, the stability between adjacent frame columns and the rigidity of the overall structure can be effectively guaranteed. This connection method is not only simple and reliable, but also convenient for construction and disassembly, improving the reconfigurability and flexibility of the building structure. In this embodiment, a connecting piece 133 is provided between two adjacent frame columns, and the connecting piece is provided with a connecting through hole 134 for connecting and fixing the connecting piece to the connecting plate using fasteners 135 through the connecting through hole and fixing holes.

[0036] In this embodiment, the choice between precast concrete floor slabs and precast steel structure floor slabs can be adjusted according to specific engineering requirements. Precast concrete floor slabs have better compressive strength and durability, while precast steel structure floor slabs have lighter weight and higher strength. This selection method can adapt to different engineering environments and requirements, improving its applicability and practicality. In this embodiment, the upper crossbeam is hollow, filled with concrete, and has pre-embedded connectors 111. These connectors are used for fixed connection to the lower crossbeam of another precast wall panel located above the upper crossbeam.

[0037] The design of filling the upper crossbeam with concrete and pre-embedding connectors not only improves the load-bearing capacity and stability of the upper crossbeam, but also provides a reliable connection point for fixed connection with the lower crossbeam of the precast wall panel above. This connection method can effectively ensure the integrity and stability of the overall structure, and improve the safety and durability of the building.

[0038] In this embodiment, a wall electrical structure is provided on one side of the calcium silicate board of the prefabricated wall panel, and electrical wiring is pre-installed in the truss structure.

[0039] In this embodiment, the prefabricated wall panel is provided with an electrical interface, and the electrical interfaces between adjacent prefabricated wall panels are adapted and connected.

[0040] In this embodiment, the electrical interface not only facilitates electrical connections between prefabricated wall panels but also improves the overall electrical performance and flexibility of the structure. Through the electrical interface, power and signals can be easily transmitted between adjacent prefabricated wall panels, providing a convenient method for the installation and maintenance of the building's internal electrical system.

[0041] In this embodiment, the prefabricated truss house includes a door 4, which includes a door frame 41 and a door body 42. The door body is hinged to the door frame. The door frame includes a door frame beam 411 and at least two door frame posts 412. The two outermost door frame posts are respectively connected between a lower crossbeam and two connecting rods forming an isosceles triangle. The bottom of each door frame post has a skirt, which is fixedly connected to the lower crossbeam by welding or fasteners. The door frame beam includes an upper door frame beam and a lower door frame beam. The two ends of the upper door frame beam are fixedly connected to the connecting rods, and the lower door frame beam is located below the lower door frame beam and is perpendicularly connected and fixed to the two door frame posts respectively.

[0042] This design not only enhances the stability and load-bearing capacity of the door but also improves the overall structural strength of the prefabricated truss house. The connection method between the door frame beam and the door frame post ensures the door's robustness, allowing it to remain stable during opening and closing, preventing wobbling or deformation. Simultaneously, the connection between the door frame post and the lower crossbeam and connecting rod further strengthens the door's stability and extends its lifespan. Furthermore, the hinged design of the door frame and door body makes opening and closing the door more flexible and convenient, providing users with a superior experience.

[0043] In this embodiment, the precast wall panels above and below the floor slab are connected and sealed by on-site grouting.

[0044] This on-site grouting connection method is not only simple to operate but also provides a strong and reliable connection. The grouting material fills the tiny gaps between prefabricated wall panels, enhancing the connection strength between the panels and thus improving the structural stability and seismic performance of the entire prefabricated truss house. Simultaneously, on-site grouting effectively isolates external moisture and humidity, protecting the internal electrical systems and structural components from corrosion and extending the house's lifespan. Furthermore, this connection method offers excellent sound and heat insulation, providing users with a quieter and more comfortable living environment.

[0045] In this embodiment, the prefabricated wall panel is equipped with a variety of sensors.

[0046] These sensors include, but are not limited to, temperature sensors, humidity sensors, smoke sensors, and infrared human body sensors. Temperature and humidity sensors monitor the temperature and humidity inside the house in real time, ensuring the living environment remains within a suitable range and improving comfort. Smoke sensors can issue timely alarms in the early stages of a fire, buying valuable escape time and ensuring safety. Infrared human body sensors detect the presence of people inside the house, thereby intelligently controlling the switching of lighting and air conditioning, achieving energy conservation and emission reduction, and improving energy efficiency. Through the installation of these sensors, the prefabricated truss house provided by this invention not only possesses higher safety and comfort but also achieves intelligent management, enhancing the quality of life.

[0047] Example 2

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a prefabricated truss house includes a floor slab 100 and a wall assembled from multiple prefabricated wall panels 200. The prefabricated wall panels 200 include a truss structure 1 and calcium silicate boards 2 attached to both sides of the truss structure. The truss structure includes an upper beam 11, a lower beam 12, and multiple connecting rods 15. Each connecting rod 15 is connected to the upper beam 11 and the lower beam 12 respectively. The multiple connecting rods are connected end to end in sequence so that adjacent connecting rods are combined with the upper beam or the lower beam to form an isosceles triangle 16. The ends of the first and last connecting rods are connected to the ends of the upper beam or the lower beam. Foamed concrete 3 is filled between the calcium silicate boards 2 attached to both sides of the truss structure. The system also includes frame columns 13, of which there are two. During on-site assembly, they are fixedly connected to both ends of the upper and lower crossbeams, respectively, to form a rectangular frame 14. The foamed concrete 3 has embedded parts 31 at both ends, which are fixedly connected to the frame columns 13. Separating the frame columns from the precast wall panels allows for matching appropriate frame columns according to actual conditions, thereby improving the structural strength of the building or reducing costs. For example, in single-story buildings, where the load-bearing capacity requirements for the wall panels and frame columns are not high, smaller frame columns can be selected. However, in multi-story buildings, frame column specifications that meet the corresponding load-bearing requirements can be selected based on the number of floors and the different load-bearing requirements. This reduces material waste during precast wall panel production, lowers the weight of the precast wall panels to some extent, and facilitates transportation.

[0049] Furthermore, to improve the structural strength and stability of the prefabricated truss house, this invention also includes angle steel connectors at the four corners of the rectangular frame, which are bolted to the frame columns and the upper and lower crossbeams. In addition, to enhance the sound insulation and thermal insulation of the house, a layer of sound-insulating and thermal-insulating material is attached to the inside of the calcium silicate board. These designs not only improve the overall performance of the prefabricated truss house but also make it more adaptable to various complex usage environments.

[0050] In this embodiment, the floor slab 100 is a precast concrete floor slab or a precast steel structure floor slab, connected to the wall by bolts or welding, ensuring the stability and robustness of the overall structure. The truss structure 1 on the precast wall panel 200 adopts an isosceles triangle structure, which is rationally designed and not only enhances the load-bearing capacity of the wall but also improves its seismic performance. Meanwhile, the calcium silicate board 2, as the wall panel material, has advantages such as being lightweight, high-strength, fireproof, and moisture-proof, further enhancing the usability of the prefabricated truss house.

[0051] Multiple connecting rods 15 installed within the rectangular frame 14 connect end-to-end with the upper beam 11 and lower beam 12 to form an isosceles triangle 16. This structural design makes the truss structure more stable and effectively resists the impact of external forces. In addition, the installation of connecting rods 15 increases the overall stiffness of the truss structure and improves the lateral force resistance of the wall.

[0052] The foamed concrete 3 filling the rectangular frame between the calcium silicate boards 2 attached to both sides of the truss structure has good thermal insulation properties, which can effectively reduce indoor temperature fluctuations and improve the living comfort of prefabricated truss houses. At the same time, foamed concrete also has the advantages of being lightweight, high-strength, and sound-insulating, further enhancing the overall performance of prefabricated truss houses.

[0053] In this embodiment, connecting plates 131 are provided at both the top and bottom of the frame columns, and fixing holes 132 are provided on the connecting plates. The connection plates and fixing holes further enhance the connection strength between the frame columns. By connecting and fixing the connecting plates with fasteners, the stability between adjacent frame columns and the rigidity of the overall structure can be effectively guaranteed. This connection method is not only simple and reliable, but also convenient for construction and disassembly, improving the reconfigurability and flexibility of the building structure. In this embodiment, a connecting piece 133 is provided between two adjacent frame columns, and the connecting piece is provided with a connecting through hole 134 for connecting and fixing the connecting piece to the connecting plate using fasteners 135 through the connecting through hole and fixing holes.

[0054] In this embodiment, the choice between precast concrete floor slabs and precast steel structure floor slabs can be adjusted according to specific project requirements. Precast concrete floor slabs have better compressive strength and durability, while precast steel structure floor slabs have lighter weight and higher strength. This selection method can adapt to different engineering environments and requirements, improving its applicability and practicality.

[0055] In this embodiment, the upper crossbeam is hollow, filled with concrete, and has a connector 111 embedded inside. The connector is used to fix and connect to the lower crossbeam of another precast wall panel located above the upper crossbeam.

[0056] The design of filling the upper crossbeam with concrete and pre-embedding connectors not only improves the load-bearing capacity and stability of the upper crossbeam, but also provides a reliable connection point for fixed connection with the lower crossbeam of the precast wall panel above. This connection method can effectively ensure the integrity and stability of the overall structure, and improve the safety and durability of the building.

[0057] In this embodiment, a wall electrical structure is provided on one side of the calcium silicate board of the prefabricated wall panel, and electrical wiring is pre-installed in the truss structure.

[0058] In this embodiment, the prefabricated wall panel is provided with an electrical interface, and the electrical interfaces between adjacent prefabricated wall panels are adapted and connected.

[0059] In this embodiment, the electrical interface not only facilitates electrical connections between prefabricated wall panels but also improves the overall electrical performance and flexibility of the structure. Through the electrical interface, power and signals can be easily transmitted between adjacent prefabricated wall panels, providing a convenient method for the installation and maintenance of the building's internal electrical system.
