At the same time, the calcium silicate board 2 as the panel material of the wall body has the advantages of light weight, high strength, fireproof, moistureproof and the like, further improving the use performance of the prefabricated truss house.

[0031] The plurality of connecting rods 15 arranged in the rectangular frame 14 are combined with the upper cross beam 11 and the lower cross beam 12 to form an isosceles triangle 16 in an end-to-end manner, which makes the truss structure more stable and can effectively resist the impact of external force. In addition, the arrangement of the connecting rod 15 also increases the overall stiffness of the truss structure and improves the lateral force resistance capacity of the wall body.

[0032] The foamed concrete 3 filled in the rectangular frame between the calcium silicate boards 2 attached to both sides of the truss structure has good heat preservation and insulation performance, which can effectively reduce the indoor temperature fluctuation and improve the living comfort of the prefabricated truss house.

[0033] In this embodiment, the top and bottom of the frame column are provided with a connecting plate 131, and the connecting plate is provided with a fixing hole 132. The connecting plate and the fixing hole further enhance the connection strength between the frame columns. By connecting and fixing the butt joint with the connecting plate through fasteners, the stability between the upper and lower adjacent frame columns and the rigidity of the overall structure can be effectively ensured. This connection method is not only simple and reliable, but also facilitates construction and disassembly, improving the reconfigurability and flexibility of the building structure.

The lower door frame beam is perpendicularly connected to the door frame column. Such design not only improves the load-bearing capacity of the door frame, but also ensures the perpendicularity and horizontality of the door frame, so that the door leaf can be smoothly opened and closed.

[0040] 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 mode of the door frame beam and the door frame column ensures the firmness of the door, so that the door can remain stable during opening and closing and is not prone to shaking or deformation.

At the same time, site grouting can effectively isolate external moisture and humidity, protecting the electrical systems and structural components inside the house from erosion and prolonging the service life of the house. In addition, this connection method also has good sound insulation and heat insulation effect, providing users with a quieter and more comfortable living environment.

[0043] In this embodiment, a variety of sensors are provided in the prefabricated wall panel.

[0044] These sensors include but are not limited to temperature sensors, humidity sensors, smoke sensors, and human infrared sensors. Temperature sensors and humidity sensors can monitor the temperature and humidity inside the house in real time, ensure that the living environment is always within the appropriate range, and improve the comfort of living. Smoke sensors can send an alarm in the early stages of a fire, giving users valuable escape time and ensuring life safety. Human infrared sensors are used to detect whether there is personnel activity in the house, so as to intelligently control the switching of lighting and air conditioning and other equipment, achieve energy saving and emission reduction, and improve energy utilization efficiency. Through the setting of these sensors, the prefabricated truss house provided by the utility model not only has higher safety and comfort, but also realizes intelligent management and improves the living quality.

[0045] The advantages of the embodiment of the utility model are as follows:

[0046] Firstly, the structural design of the prefabricated wallboard makes it have high strength and stability. Since the truss structure is composed of multiple connecting rods, upper and lower cross beams, and two frame columns, and the connecting rods form isosceles triangles between them, this design enhances the overall rigidity and seismic performance of the wallboard. At the same time, the calcium silicate board as the surface material of the wallboard has excellent fireproof, waterproof and corrosion-resistant performance, further improving the safety of the wallboard in use.

[0047] Secondly, the prefabricated wallboard has good thermal insulation performance. The foam concrete filled in the rectangular frame is a high-quality thermal insulation material that can effectively insulate the influence of external cold and hot air on indoor temperature, thereby maintaining the constancy of indoor temperature. This is of great significance to improve the living comfort and energy saving effect of prefabricated truss houses.

[0048] In addition, the prefabricated wallboard also has the advantages of convenient construction and high installation efficiency. Since the wallboard is a prefabricated part, it can be produced in the factory and transported to the construction site for assembly, greatly shortening the construction period. At the same time, the connection between the wallboards is simple and reliable, reducing the construction difficulty and cost.
