Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Embodiment 1

[0031] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a prefabricated truss house includes a floor slab 100 and a wall body assembled by a plurality of prefabricated wall panels 200. The prefabricated wall panel 200 includes a truss structure 1 and calcium silicate boards 2 attached to both side surfaces of the truss structure. The truss structure 1 includes a rectangular frame 14 composed of an upper cross beam 11, a lower cross beam 12, and two frame columns 13. A plurality of connecting rods 15 are arranged in the rectangular frame. Each connecting rod is respectively connected to the upper cross beam and the lower cross beam. The plurality of connecting rods are connected end to end in sequence, so that adjacent two connecting rods and the upper cross beam or the lower cross beam are combined to form an isosceles triangle 16. The ends of the first and the last connecting rods are connected to the top corners 141 of the rectangular frame. Foamed concrete 3 is filled in the rectangular frame between the calcium silicate boards 2 attached to both side surfaces 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, and is connected to the wall body by bolts or welding, ensuring the stability and firmness of the overall structure. The truss structure 1 on the prefabricated wall panel 200 adopts an isosceles triangle structure, with reasonable design, which not only enhances the load-bearing capacity of the wall body, but also improves the seismic performance of the wall body. At the same time, as the wall panel material of the wall body, the calcium silicate board 2 has the advantages of light weight, high strength, fire resistance, moisture resistance, etc., further improving the service performance of the prefabricated truss house.

[0033] A 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 by connecting end to end to form an isosceles triangle 16. This structural design makes the truss structure more stable and can effectively resist the impact of external forces. In addition, the setting of the connecting rods 15 also increases the overall stiffness of the truss structure and improves the lateral force resistance ability of the wall body.

[0034] The foamed concrete 3 filled in the rectangular frame between the calcium silicate boards 2 attached to both side surfaces of the truss structure has good heat insulation and sound insulation performance, can effectively reduce the temperature fluctuation in the room, and improve the living comfort of the prefabricated truss house. At the same time, the foamed concrete also has the advantages of light weight, high strength, sound insulation, etc., further improving the overall performance of the prefabricated truss house.

[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 arrangement of the connecting plates and the fixing holes further enhances the connection strength between the frame columns. By connecting and fixing the docking members to the connecting plates with fasteners, the stability between adjacent upper and lower frame columns and the rigidity of the overall structure can be effectively ensured. 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 docking member 133 is provided between two adjacent upper and lower frame columns, and a connection through-hole 134 is provided on the docking member for connecting and fixing the docking member to the connecting plate with a fastener 135 through the connection through-hole and the fixing hole.

[0036] In this embodiment, the selection of the precast concrete floor slab or the precast steel structure floor slab can be adjusted according to the specific project requirements. The precast concrete floor slab has good compressive performance and durability, while the precast steel structure floor slab has a lighter weight and higher strength. This selection method can adapt to different engineering environments and requirements, improving its application range and practicability. In this embodiment, the upper cross beam is hollow, filled with concrete inside and embedded with a connecting member 111, and the connecting member is used for fixedly connecting with the lower cross beam of another precast wall panel located above the upper cross beam.

[0037] The design of filling the upper cross beam with concrete and embedding the connecting member not only improves the bearing capacity and stability of the upper cross beam, but also provides a reliable connection point for fixedly connecting with the lower cross beam of the upper precast wall panel. This connection method can effectively ensure the integrity and stability of the overall structure, improving the safety and durability of the building.

[0038] In this embodiment, a wall electrical structure is provided on the calcium silicate board on one side of the precast wall panel, and electrical lines are preset in the truss structure.

[0039] In this embodiment, electrical interfaces are provided on the precast wall panels, and the electrical interfaces between adjacent precast wall panels are adaptively connected.

[0040] In this embodiment, the arrangement of the electrical interfaces not only facilitates the electrical connection between the precast wall panels, but also improves the electrical performance and flexibility of the overall structure. Through the electrical interfaces, power and signals can be easily transmitted between adjacent precast wall panels, providing a convenient installation and maintenance method for the electrical system inside the building.

[0041] In this embodiment, the prefabricated truss house includes a door 4, which includes a door frame 41 and a door leaf 42. The door leaf is hinged to the door frame. The door frame includes a door frame beam 411 and at least two door frame columns 412. The two outermost door frame columns are respectively connected between the lower cross beam and two connecting rods forming an isosceles triangle. A skirt is provided at the bottom of the door frame column, and the skirt is fixedly connected to the lower cross beam by welding or by 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 columns 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 of the door frame beam and the door frame column ensures the firmness of the door, making the door stable during the opening and closing process and not prone to shaking or deformation. At the same time, the connection of the door frame column to the lower cross beam and the connecting rods further enhances the stability of the door and improves the service life of the door. In addition, the hinged design of the door frame and the door leaf makes the door more flexible and convenient to open and close, providing a good user experience.

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

[0044] This on-site grouting connection method is not only simple to operate, but also has a firm and reliable connection effect. The grouting material can fill the tiny gaps between the precast wall panels, enhance the connection strength between the wall panels, and thus improve the structural stability and seismic performance of the entire prefabricated truss house. At the same time, on-site grouting can effectively isolate external moisture and dampness, protect the electrical systems and structural components inside the house from erosion, and extend the service life of the house. In addition, this connection method also has good sound insulation and heat insulation effects, providing a quieter and more comfortable living environment for users.

[0045] In this embodiment, a variety of sensors are provided inside the precast wall panel.

[0046] These sensors include, but are not limited to, temperature sensors, humidity sensors, smoke sensors, and human infrared sensors. The temperature sensor and the humidity sensor can monitor the temperature and humidity inside the house in real time, ensure that the living environment is always maintained within a suitable range, and improve the comfort of living. The smoke sensor can issue an alarm in the early stage of a fire, buying precious escape time for users and ensuring life safety. The human infrared sensor is used to detect whether there are people moving inside the house, thereby intelligently controlling the switching of devices such as lighting and air conditioning, achieving energy conservation and emission reduction, and improving energy utilization efficiency. Through the setting of these sensors, the prefabricated truss house provided by the present invention not only has higher safety and comfort, but also realizes intelligent management and improves the living quality.

[0047] Example 2

[0048] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, a prefabricated truss house includes a floor slab 100 and a wall formed by assembling a plurality of precast wall panels 200. The precast wall panel 200 includes a truss structure 1 and calcium silicate boards 2 attached to both side surfaces of the truss structure. The truss structure includes an upper cross beam 11, a lower cross beam 12, and a plurality of connecting rods 15. Each connecting rod 15 is respectively connected to the upper cross beam 11 and the lower cross beam 12. The plurality of connecting rods are connected end to end in sequence, so that adjacent two connecting rods and the upper cross beam or the lower cross beam form an isosceles triangle 16. The ends of the first and the last connecting rods are connected to the ends of the upper cross beam or the lower cross beam. Foam concrete 3 is filled between the calcium silicate boards 2 attached to both side surfaces of the truss structure. It further includes frame columns 13. There are two frame columns 13, which are fixedly connected to the two ends of the upper cross beam and the lower cross beam respectively during on-site assembly, thus forming a rectangular frame 14. Embedded parts 31 are provided at both ends of the foam concrete 3, and the embedded parts 31 are fixedly connected to the frame columns 13. By separately arranging the frame columns and the precast wall panels, appropriate frame columns can be matched according to actual situations, thereby improving the structural strength of the house or reducing costs. For example, in the case of a single-story house, the requirements for the load-bearing capacity of the house wall panels and frame columns are not high, and frame columns with smaller specifications can be selected; while in the assembly of multi-story houses, frame column specifications that meet the corresponding load-bearing requirements can be selected according to the different number of floors and load-bearing requirements of the house. Thereby reducing the material loss during the prefabrication of the precast wall panels, and to a certain extent reducing the weight of the precast wall panels, which is convenient for transportation.

[0049] Furthermore, in order to improve the structural strength and stability of the prefabricated truss house, the present invention also provides angle steel connectors at the four corners of the rectangular frame, and the angle steel connectors are fixedly connected to the frame columns, the upper cross beam, and the lower cross beam through bolts. In addition, in order to enhance the sound insulation and heat preservation effects of the house, a layer of sound insulation and heat preservation material is also attached to the inner side 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, which is connected to the wall by bolts or welding, ensuring the stability and firmness of the overall structure. The truss structure 1 on the precast wall panel 200 adopts an isosceles triangle structure, with reasonable design, which not only enhances the load-bearing capacity of the wall but also improves the seismic performance of the wall. At the same time, calcium silicate board 2, as the panel material of the wall, has the advantages of light weight, high strength, fire resistance, moisture resistance, etc., further improving the service performance of the assembled truss house.

[0051] A plurality of connecting rods 15 arranged within the rectangular frame 14 are combined with the upper cross beam 11 and the lower cross beam 12 in a head-to-tail connection manner to form an isosceles triangle 16. This structural design makes the truss structure more stable and can effectively resist the impact of external forces. In addition, the setting of the connecting rods 15 also increases the overall stiffness of the truss structure and improves the lateral force resistance ability of the wall.

[0052] The foam concrete 3 filled within the rectangular frame between the calcium silicate boards 2 attached to both side surfaces of the truss structure has good heat insulation performance, which can effectively reduce the indoor temperature fluctuation and improve the living comfort of the assembled truss house. At the same time, the foam concrete also has the advantages of light weight, high strength, sound insulation, etc., further enhancing the overall performance of the assembled truss house.

[0053] In this embodiment, connecting plates 131 are provided at both the top and bottom of the frame column, and fixing holes 132 are provided on the connecting plates. The setting of the connecting plates and the fixing holes further enhances the connection strength between the frame columns. By connecting and fixing the docking member to the connecting plate with 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 convenient for construction and disassembly, improving the reconfigurability and flexibility of the building structure. In this embodiment, a docking member 133 is provided between two adjacent upper and lower frame columns, and a connection through hole 134 is provided on the docking member for connecting and fixing the docking member to the connecting plate with fasteners 135 through the connection through hole and the fixing hole.

[0054] In this embodiment, the selection of the precast concrete floor slab or the precast steel structure floor slab can be adjusted according to the specific engineering requirements. The precast concrete floor slab has good compressive performance and durability, while the precast steel structure floor slab has a lighter weight and higher strength. This selection method can adapt to different engineering environments and requirements, improving its application range and practicability.

[0055] In this embodiment, the upper cross beam is hollow, filled with concrete inside and embedded with a connecting member 111, and the connecting member is used for fixedly connecting with the lower cross beam of another precast wall panel located above the upper cross beam.

[0056] The design of filling the upper crossbeam with concrete and pre-embedding connecting pieces not only improves the bearing capacity and stability of the upper crossbeam, but also provides a reliable connection point for the 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 the calcium silicate board on one side of the precast wall panel, and electrical lines are preset in the truss structure.

[0058] In this embodiment, electrical interfaces are provided on the precast wall panels, and the electrical interfaces between adjacent precast wall panels are adaptively connected.

[0059] In this embodiment, the setting of the electrical interfaces not only facilitates the electrical connection between the precast wall panels, but also improves the electrical performance and flexibility of the overall structure. Through the electrical interfaces, power and signals can be easily transmitted between adjacent precast wall panels, providing a convenient installation and maintenance method for the electrical system inside the building.

[0060] In this embodiment, the prefabricated truss house includes a door 4, the door 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 columns 412, and the two outermost door frame columns are respectively connected between the lower crossbeam and two connecting rods forming an isosceles triangle. 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 vertically and fixedly connected to the two door frame columns respectively.

[0061] 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 of the door frame beam and the door frame columns ensures the firmness of the door, so that the door can remain stable during the opening and closing process and is not prone to shaking or deformation. At the same time, the connection of the door frame columns to the lower crossbeam and the connecting rods further enhances the stability of the door and improves the service life of the door. In addition, the hinged design of the door frame and the door body makes the door more flexible and convenient to open and close, providing a good user experience for users.

[0062] In this embodiment, the precast wall panel above the floor and the precast wall panel below are connected and sealed by on-site grouting.

[0063] This on-site grouting connection method is not only simple to operate but also has a firm and reliable connection effect. The grouting material can fill the tiny gaps between precast wall panels, enhancing the connection strength between the wall panels, thereby improving the structural stability and seismic performance of the entire prefabricated truss house. At the same time, on-site grouting can also effectively isolate external moisture and dampness, protecting the electrical systems and structural components inside the house from erosion and extending the service life of the house. In addition, this connection method also has good sound insulation and heat insulation effects, providing a quieter and more comfortable living environment for users.

[0064] In this embodiment, a variety of sensors are provided inside the precast wall panel.

[0065] These sensors include, but are not limited to, temperature sensors, humidity sensors, smoke sensors, and human infrared sensors. The temperature sensor and humidity sensor can monitor the temperature and humidity inside the house in real time, ensuring that the living environment always remains within a suitable range and improving the living comfort. The smoke sensor can issue an alarm in the early stage of a fire, buying precious escape time for users and ensuring life safety. The human infrared sensor is used to detect whether there are people moving inside the house, thereby intelligently controlling the switches of lighting and air conditioning equipment, achieving energy conservation and emission reduction, and improving energy utilization efficiency. Through the setting of these sensors, the prefabricated truss house provided by the present invention not only has higher safety and comfort but also realizes intelligent management and improves the living quality.
