[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0047] like Figures 1 to 11 As shown, the modular assembled building structure of the present invention includes at least one group of assembled building modules, and the building modules include a group of support frame units 1, one or two groups of functional wall units 3 that match the shape of the support frame units 1, and the functional wall units 3 are installed on the support frame units 1 in a detachable manner. The support frame unit 1 is formed into a polygonal structure by splicing multiple groups of support rods 2 end to end in sequence. Among the multiple groups of support rods 2 of the support frame unit 1, at least one group of support rods 2 is vertically arranged, and at least one group of support rods 2 is horizontally arranged to ensure the stability of the structure. The support frame unit 1 can be a triangle, rectangle or other polygonal structure. In this embodiment, the support frame unit 1 is square. Multiple groups of support frame units 1 are spliced ​​and fixedly connected to each other, and two adjacent groups of support frame units 1 share a group of support rods 2. The modular assembled building structure of the present invention can be composed of only one group of building modules to form a standardized module; the modular assembled building structure of the present invention can also be composed of multiple groups of building modules that are spliced ​​and fixed to each other in a detachable manner, and the support frame units 1 of two adjacent groups of building modules share a group of support rods 2. The support frame units 1 of each group of building modules are spliced ​​to form a main support frame, and the functional wall units 3 of each group of building modules are combined to form walls and embedded wall functional components.

[0048] The support rod 2 includes a support tube 21, two joints 22 respectively located at the two ends of the support tube 21, and two connecting rods 23. The two joints 22 are respectively connected to the two ends of the support tube 21 through the connecting rods 23, wherein the support tube 21 is a square tube or an octagonal tube, and the inner cavity of the support tube 21 is a regular octagonal structure. A plurality of threaded fixing holes 221 are opened on the outer surface of the joint 22, and the first end of the connecting rod 23 is provided with an external thread 231 and is threadedly fixedly connected to the threaded fixing hole 221 of the corresponding joint 22. The second end of the connecting rod 23 is an octagonal prism structure matching the inner cavity of the support tube, and the second end of the connecting rod 23 is axially inserted into the corresponding end of the support tube 21 and is fixedly connected to the support tube 21 by a screw 24; a joint 22 is shared by two adjacent groups of support rods 2 in the support frame unit 1.

[0049] The supporting profile tube 21 of each group of supporting rods 2 in the supporting frame unit 1 is fixedly connected with a connecting piece 25 by means of screws 24, and each connecting piece 25 is fixedly connected with the functional wall unit 3 by means of a mortise and tenon structure or screws. The connecting piece 25 can be a single-sided structure or a double-sided structure, and a connecting portion 251 extends from the front end or rear end of the single-sided connecting piece 25, and a connecting portion 251 for connecting with the functional wall unit 3 extends from the front end and rear end of the double-sided connecting piece 25. Fig.10 As shown, the support frame unit 1 can only be equipped with a set of functional wall units 3 on the front end face or the rear end face, and the functional wall units 3 are respectively installed on the front end face or the rear end face of the support frame unit 1 through the single-sided joint piece 25. Fig.11 As shown, the supporting frame unit 1 may also have functional wall units 3 installed on both the front and rear end surfaces, and two groups of functional wall units 3 are respectively installed on the front and rear end surfaces of the supporting frame unit 1 through double-sided connectors 25 .

[0050] The functional wall unit 3 is an outer wall component, an inner wall component, a door and window component, a kitchen component, a bathroom component, a lighting component, an air-conditioning component or a staircase component. By making the outer wall component, the inner wall component, the door and window component, the kitchen component, the bathroom component, the lighting component, the air-conditioning component or the staircase component into a modular functional wall unit 3, the construction speed is greatly improved.

[0051] There are 18 threaded fixing holes 221 on the outer surface of the joint 22, wherein the joint 22 takes its center as the origin, 8 threaded fixing holes 221 are evenly distributed along the circumference on the XY axis plane, 8 threaded fixing holes 221 are evenly distributed along the circumference on the XZ axis plane, and 8 threaded fixing holes 221 are evenly distributed along the circumference on the YZ axis plane. The joint 22 is an equilateral 48-prism, and the outer surface forms 26 faces, including 18 square faces and 8 equilateral triangle faces, and the centers of the 18 square faces are all provided with threaded fixing holes 221. Through this joint 22, the two groups of support rods 2 can be assembled at different angles such as 45°, 90°, 135° and 180°, thereby improving the assembly flexibility and being able to assemble main support frames of various shapes.

[0052] When assembling the outer wall building structure, the supporting tube 21 adopts an octagonal tube, which can be connected with the joint 22 at 45°, 90°, 135° and 180° to form a variety of faces, among which the tetrahedrons at 90° and 180° have the function of the principal stress surface, the tetrahedrons at 45° and 135° have the function of the principal shear stress surface, and the oblique triangular face has the function of the stress surface; this mechanical theorem and mathematical model are based on the "Unified Strength Theory and Its Application" published in 2004 by Professor Yu Maohong, a doctoral supervisor at Xi'an Jiaotong University. In 2018, Professor Yu Maohong proposed the 26-faced stress strength theory, which unified the linear single shear, double shear theory and the nonlinear triple shear theory.

[0053] When assembling the interior wall structure, the supporting tube 21 is a square tube, which is connected with the joint 22 to form a 90° and 180° tetrahedron. In addition to having the function of a mechanical principal stress surface, it also has design functions such as indoor partitions, traffic line planning and interior decoration.

[0054] Therefore, the mechanical structure of the building body uses octagonal tubes, and the interior decoration of the building body uses square tubes. The diversification of the structural angles is increased by using two types of tubes at four angles, and the support tube type and the joint 22 are connected equidistantly in all directions to increase the strength of the shear force, and the point-line-surface mesh structure is used to increase the toughness of the rigid structure.

[0064] C. Install several functional wall units 3 to each group of supporting frame units 1 of the main supporting frame through the connecting pieces 25 to complete the construction of the modular assembled building structure.

[0065] The present invention can also splice two assembled building structures together, and the corresponding joints 22 of the main support frames of the two building structures are connected together through the support pipe 21 and the connecting rod 23 in a manner of assembling the support rod 2.

[0067] The main support frame of the building structure of the present invention is formed by splicing a number of support rods 2. The functional wall unit 3 and the parts constituting the support rods 2 are all standardized and modular components.
