[0002] Prefabricated modular houses and container houses are standard-sized temporary buildings with light steel frames, thin steel plates as enclosure materials, rock wool as insulation materials, and bolted connections. Due to their ease of assembly and integrated production, they have become popular temporary construction sites and office spaces. However, existing prefabricated houses require connectors and manual bolting for panel connection, resulting in numerous steps, long construction cycles, and complex installation processes, which are unsuitable for the development requirements of prefabricated housing. Furthermore, the connection structure is irreversible, cannot be reused after dismantling, and generates construction waste, failing to meet green environmental protection requirements. In addition, they suffer from poor insulation and easy rusting of the sheet metal during later use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a green, environmentally friendly, low-carbon, energy-saving, quick and easy to assemble and disassemble, movable modular six-dimensional tenon and mortise structure permanent building composite panel that integrates structure, enclosure, heat preservation and decoration. The house can be built by directly splicing two components, composite wall panels and floor panels. The installation and disassembly are convenient and quick, and it has the characteristics of high installation efficiency and good stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A modular six-dimensional tenon-and-mortise structure four-in-one composite panel includes wall panels and floor slabs. Each wall panel and floor slab includes a panel, supporting joists, an insulation layer, and edge-sealing steel components. Supporting joists are installed inside the inner and outer panels, and edge-sealing steel components are installed on all four sides of the panels. The wall panel, formed by the panels and edge-sealing steel components, is filled with insulation material to form an insulation layer. The edge-sealing steel components include shaped steel and shaped tubing. The left and right sides of the wall panel are edge-sealed with shaped tubing, and the top and bottom ends are edge-sealed with shaped steel. The grooves formed by the sidewalls of the shaped tubing correspond to the shaped steel. The four sides of the floor slab are edge-sealed with shaped tubing.

[0006] The above-mentioned six-dimensional tenon and mortise structure four-in-one composite board includes a floor slab with joints set at the four corners of the floor slab. The joints are fixedly installed between every two adjacent irregular tubes. The joints are irregular tubes with equal length, width and height. The joints are arranged vertically and perpendicular to the extension direction of the irregular tubes.

[0007] The above-mentioned module is a six-dimensional tenon and mortise structure four-in-one composite panel. The panel includes a reinforcing mesh and a decorative panel. The supporting keel is a number of steel pipes or reinforcing bars arranged vertically and evenly, with horizontal bracing between the steel pipes or reinforcing bars.

[0008] The above-mentioned module is a six-dimensional tenon and mortise structure four-in-one composite panel. The irregular tube has a central square tube in the middle, and four square tubes are symmetrically arranged at the four corners of the central square tube. Adjacent square tubes form trapezoidal grooves, and the trapezoidal grooves and the steel sections form a tenon and mortise structure. The floor slabs and wall panels are inserted and assembled into a house in a certain order.

[0009] A sheet forming machine for composite sheets as described above includes a gantry frame, an upper mold, a lower mold table, a lifting mechanism, and a limiting mechanism. The upper mold is a cuboid structure, and its dimensions correspond to those of the lower mold table. A gantry frame is installed on the outer side of the lower mold table, and the gantry frame is composed of several frames, with a lifting mechanism installed inside each frame. The lifting mechanism is connected to the upper mold, and its movement drives the upper mold to move up and down. A positioning slot is formed on the upper surface of the lower mold table, and a limiting mechanism is installed within the positioning slot.

[0010] The aforementioned sheet metal forming machine includes a lifting motor, connecting rods, a steering mechanism, and a lead screw assembly. The lifting motors are symmetrically arranged at both ends of the upper part of one side of the gantry frame. The lifting motors are connected to the connecting rods, and a steering mechanism is installed at each frame. The lead screw assembly is installed inside each frame. The lead screw assembly includes a lead screw, a nut, and an upper mold connector. The top end of the lead screw is connected to the vertical end of the steering mechanism. The nut is fitted onto the lead screw, and the upper mold connector is fixed to the side wall of the nut. The upper mold connector is connected to the upper mold. The operation of the lifting motor drives the connecting rod to rotate, which in turn causes the lead screw to rotate via the steering mechanism, thereby moving the nut and the upper mold up and down along the lead screw.

[0011] The aforementioned sheet metal forming machine includes an ejector cylinder and an ejector block. The size of the positioning slot hole of the lower mold table matches the ejector block. The ejector blocks are distributed around the lower mold table, and the four corners of the lower mold table are L-shaped ejector blocks. An ejector cylinder is provided at the bottom of the ejector block.

[0012] The above-mentioned sheet metal forming machine is equipped with a pressing mechanism. The pressing mechanism is located in the middle of the gantry frame. The pressing mechanism includes a two-way cylinder, an upper pressure plate and a lower pressure plate. The upper pressure plate is fixed to the bottom of the crossbeam and the lower pressure plate is fixed to the upper mold. The two-way cylinder is located between the upper and lower pressure plates. The two piston rod ends of the two-way cylinder are respectively connected to the upper and lower pressure plates on the same side.

[0013] This utility model utilizes a six-dimensional mortise and tenon structure with two modular components, and four-in-one (structure, enclosure, insulation, and decoration) wall panels and floor slabs. Houses are directly constructed through interlocking connections, resulting in high construction efficiency and speed. Compared to traditional construction methods, the construction cycle can be shortened by more than 90%, and the assembly rate can reach 100%, far exceeding the national standard of 75%. The constructed houses are safe and sturdy, with high fire resistance and seismic resistance. The composite panels integrate structural, enclosure, insulation, and decorative functions, avoiding the need for separate construction steps such as adding insulation layers and decorative panels required by existing building materials, which only have a single function. Furthermore, the constructed houses can be quickly and repeatedly disassembled and moved, and the disassembled panels can be 100% recycled and reused, filling a gap in domestic and international architectural history and rewriting the history of permanent buildings that cannot be repeatedly and quickly disassembled and moved. The shaped tubes are high-strength aluminum alloy or steel pipes, forming a square axisymmetric structure with a central square tube and four corner square tubes, offering excellent resistance to compression and bending. The composite panels and shaped tube steel structure beams and columns are connected as a single unit using high-pressure, high-density polyurethane composite bonding. The assembly tenon and mortise joint tolerance is ≤1.0mm, enabling seamless assembly and locking, reducing construction difficulty, and facilitating convenient and quick installation and disassembly. The entire construction process is dry, fully complying with green and environmentally friendly requirements, achieving green, industrialized, and intelligent construction throughout the building's entire lifecycle.

[0014] The large-scale board forming machine adopts an automated production process. Through an intelligent control system, it automatically completes steps such as tile laying, upper mold movement and positioning, upper mold clamping, intelligent foaming and injection, and automatic rolling demolding after being lifted by a cylinder. This solves the problem of low efficiency and difficulty in achieving rapid and standardized production of large-format boards in existing board production equipment. It is equipped with an intelligent mold clamping mechanism, an intelligent automatic tile feeding system, an intelligent automatic tile laying system, a finished product demolding intelligent system, an intelligent foaming and injection module, a robotic arm, and a laser welding system.

[0015] This utility model utilizes a high-efficiency sheet forming machine and supporting automated forming equipment to quickly produce composite panels. It employs a rapid construction method using mortise and tenon joints, providing a prefabricated building solution that can be quickly and repeatedly disassembled and reused. It features a wide range of applications and good sturdiness, making it suitable for military barracks, border outposts, fire stations, guesthouses, villas, and other prefabricated buildings that require repeated disassembly and relocation or are permanent.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2 , Figure 3As shown, the composite panel of this utility model includes a wall panel 1 and a floor slab 2. The wall panel and floor slab can be directly assembled into a house by interlocking them in a certain order. The wall panel 1 includes a panel, supporting keel 7, insulation layer 63, and edge sealing steel parts. Vertical supporting keels 7 are set inside the inner and outer panels. Edge sealing steel parts are set on the four sides of the panel. The wall panel formed by the panel and edge sealing steel parts is filled with polyurethane insulation material to form the insulation layer 63. The panel can be a pressure cement board, corrugated board, or a combination panel composed of steel wire reinforcing mesh 62 and decorative panels 61 such as ceramic tiles and marble. The panel also has a decorative function and can be used directly as a wall or floor slab, reducing the need for later decoration and renovation. The supporting keel 7 is a number of vertically evenly arranged steel pipes or reinforcing bars. The steel pipes or reinforcing bars are welded together by horizontal braces 71 to form the keel of the wall, so as to enhance the shear resistance of the wall panel and the bending resistance of the floor slab, thereby increasing the stability of the house. The insulation layer 63 is made of high-density flame-retardant rigid polyurethane foam with a density of ≥45kg / m³ and a flame retardant rating of B1, which better meets the requirements of the building.

[0035] The edge-sealing steel components include 64-shaped steel and 3-shaped tubes. Longer wall panels in the building are edge-sealed with 3-shaped tubes on both sides and with 64-shaped steel at the top and bottom. Shorter wall panels are edge-sealed with 64-shaped steel on all four sides. The 3-shaped tube has a central square tube, with symmetrical square-like tubes at its four corners, forming trapezoidal grooves between adjacent square-like tubes. The two outer sides of the square-like tubes are right-angled, and the two inner hypotenuses intersect with the two sides of one corner of the central square tube. This square axisymmetric structure formed by the central square tube and the four corner square-like tubes gives the 3-shaped tube the shear and compressive strength of a beam or column. The special-shaped tube is made of high-strength aluminum alloy with a thickness of 2.0-4.0mm; the 64-shaped steel is a steel plate with protrusions along the axial direction, and the protrusions are arranged outward so that the side of the wall panel with the 64-shaped steel forms a boss; the boss of the 64-shaped steel corresponds to the trapezoidal groove of the special-shaped tube to form a matching mortise and tenon structure. The wall panel and the floor slab are connected by mortise and tenon joints, thereby realizing the rapid assembly of the house in multiple dimensions in the horizontal and vertical directions.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the floor slab 2 includes a panel, supporting keel 7, insulation layer 63, special-shaped pipes 3, and joints 5. Supporting keels 7 are installed inside the panel, and these keels are several steel pipes or reinforcing bars arranged in a triangular pattern. The supporting keels extend along the length of the floor slab, and the steel pipes or reinforcing bars are welded together by cross braces 71. The ends of the supporting keels and cross braces of the floor slab and wall panels are welded and fixed to the edge-sealing steel components to form an integral steel frame. Therefore, the floor slab and wall panels can bear loads and can be used to construct multi-story buildings, improving the applicability of modular standard components. Special-shaped pipes 3 are installed on the four sides of the panel, and a joint 5 is installed between every two adjacent special-shaped pipes. The joint 5 is a special-shaped pipe with equal length, width, and height; the joints are arranged vertically, perpendicular to the extension direction of the special-shaped pipes.

[0037] Wall panel 1 and floor slab 2 together form composite panel 6. The composite panel is prefabricated in the factory and can be made in standard size or customized according to requirements. The size range is 2.0-12.0m in length, 0.6-3.0m in width, and 100-300mm in thickness. The standard composite panel is 6m in length, 3m in width, and 140mm in thickness. The composite panel, which consists of inner and outer reinforcing mesh 62, decorative panel 61, and middle insulation layer with four sides sealed by steel profiles and special-shaped pipes, has the functions of structure, enclosure, insulation and decoration. The composite panel has a compressive strength ≥15MPa and a heat transfer coefficient ≤0.19W / (m²·K), and has the function of modular house panels.

[0038] like Figure 1 , Figure 6 As shown, the construction process for terraced houses is as follows:

[0039] Step 1: Lay the foundation according to the house drawings, pre-embed the insert pipe 8 in the foundation, the insert pipe extends out of the ground, and concrete is poured into the pipe to form a ground pile. The ground surface is leveled. The insert pipe 8 is a short square tube, slightly smaller than the central square tube of the special-shaped tube. It can be fitted into the central square tube of the special-shaped tube or the connector 5. The insert pipe 8, special-shaped tube 3, and connector 5 work together to achieve direct insertion and construction of wall panels and floor slabs. The insert pipe is made of stainless steel or aluminum alloy. Adjacent rooms in the row house share a wall panel, and adjacent floor slabs share a special-shaped tube. That is, one floor slab is a special-shaped tube, and adjacent floor slabs are made of shaped steel, and the two are joined by mortise and tenon joints.

[0040] Step 2: The floor slab is hoisted above the foundation using a crane. The joints at the four corners of the floor slab are inserted into the corresponding insertion tubes and placed on the ground as the floor. The joint height between adjacent floor slabs is half the normal joint height (70mm). When overlapping, the two joints are spliced ​​together vertically to form a complete joint. Two long wall panels are hoisted and placed above the floor slab, so that the steel protrusions on the bottom edge of the wall panels are inserted into the grooves of the special-shaped tubes of the floor slab. Then, two short wall panels are placed between the two long wall panels and connected and fixed to each other using mortise and tenon joints to form four wall panels. Door openings and window openings are reserved on the two opposite wall panels. The floor slab is placed on top of the wall panels as the roof slab, and insertion tubes are inserted into the joints of the floor slab, extending into the special-shaped tubes of the wall panels, thereby connecting the roof slab to the four wall panels. In this way, the six sides of the house are directly fixed through mortise and tenon joints, thus completing the construction of a house. Because of the mortise and tenon structure, the wall panels and floor slabs are assembled without gaps, which provides better sealing than straight connections. At the same time, the grooves of the irregular tubes in the floor slabs have a certain depth, which makes them firmly connected with the steel protrusions of the wall panels. They are not easy to slip out when subjected to shear force. After the house is built, the wall panels, floor slabs and steel beams and columns restrain each other and limit displacement, making the connection method safe and reliable.

[0041] Step 3: After assembling the walls and floor slabs of the first floor, install the wall panels and roof slabs of the second floor in sequence; water and electricity pipelines are pre-embedded in the cavities or special-shaped pipes of the supporting keel. After completing the water and electricity pipelines and interior decoration, a two-story house can be delivered for use.

[0042] like Figure 7 , Figure 8 As shown, the composite board 6 is produced automatically by a board forming machine. The board forming machine includes a gantry frame 9, an upper mold 11, a lower mold platform 12, a lifting mechanism 10, a pressing mechanism, a limiting mechanism, and a control system. There are two lower mold platforms 12, which are parallel and of equal height. The upper surface of the lower mold platform 12 has positioning lines and positioning slots with standard dimensions, and a limiting mechanism is installed in the positioning slots. The upper mold 11 is a cuboid structure, and its dimensions correspond to those of the lower mold platform. Several support plates are installed inside the cuboid to enhance its stability. A gantry frame 9 is installed on the outside of the lower mold platform 12. The gantry frame 9 consists of several frames, with a crossbeam at the top. Two columns are symmetrically arranged at both ends of the crossbeam, and a lifting mechanism 10 is installed inside each column. The lifting mechanism 10 is connected to the upper mold 11, and its operation drives the upper mold to move up and down.

[0043] The bottom of the gantry frame is equipped with traveling wheels 15 and a traveling motor 14. Tracks are laid on both sides of the lower mold platform. Traveling wheels 15, symmetrically installed at the bottom of the frame and cooperating with the tracks, are divided into two driving wheels at one end of the gantry and two driven wheels at the other. The driving wheels are connected to the traveling motor 14, which drives the traveling wheels to rotate, allowing the gantry frame to move between the two lower mold platforms. Locking blocks are installed between the side wall of the lower mold platform and the gantry frame to lock and fix the upper mold and gantry frame in the position of the lower mold platform during composite board preparation. A pressing mechanism 20 is installed in the middle of the gantry beam. The pressing mechanism 20 includes a bidirectional cylinder, an upper pressure plate, and a lower pressure plate. The upper pressure plate is fixed to the bottom of the beam, and the lower pressure plate is fixed to the upper mold. The bidirectional cylinder is positioned between the upper and lower pressure plates, with the two piston rods of the bidirectional cylinder connected to the upper and lower pressure plates on the same side, respectively. When polyurethane is filled, the bidirectional cylinder contracts, pressing the lower pressure plate against the surface of the upper mold to prevent the upper mold from being lifted during expansion.

[0044] like Figure 9As shown, the lifting platform 10 includes a lifting motor 13, a connecting rod 131, a steering gear 132, and a lead screw assembly. The lifting motor 13 is symmetrically arranged on the upper part of one end of the gantry frame. The lifting motor 13 is connected to the connecting rod 131, which extends to the other end of the gantry frame. The connecting rod is a hexagonal column, and the motor's rotating shaft is connected to the connecting rod using internal and external hexagonal joints. A steering gear 132 is provided at each position of the connecting rod and is connected to the horizontal end of the steering gear. A lead screw assembly is provided inside the frame, and the top end of the lead screw assembly is connected to the vertical end of the steering gear. The steering gear consists of two meshing helical bevel gears. The lead screw assembly includes a lead screw 101, a nut 102, and an upper mold connecting piece 103. The nut 102 is sleeved on the lead screw 101, and the upper mold connecting piece 103 is fixed to the outside of the nut 102. The upper mold connecting piece 103 is connected to both sides of the upper mold. The lifting motor 13 drives the connecting rod 131 to rotate, and the horizontal rotation of the connecting rod is changed into the vertical rotation of the lead screw through the steering gear 132, which drives the nut and the upper mold connecting part 103 to move up and down, thereby moving the upper mold up and down along the lead screw. The lifting platform can also be used for lifting the upper mold table with a hydraulic cylinder.

[0045] like Figure 10 , Figure 11 As shown, a limiting mechanism and an automatic loading and unloading mechanism are provided on the lower mold platform. The automatic loading and unloading mechanism includes a rubber roller cylinder 16 and a rubber roller 17. The limiting mechanism includes an ejector cylinder 19 and an ejector block 18. Several positioning slots are opened on the upper surface of the lower mold platform, and the size of the slots matches the rubber roller 17 or the ejector block 18. The ejector blocks 18 are distributed around the periphery of the lower mold platform. The four corners of the lower mold platform are L-shaped ejector blocks, and the middle of the long side of the lower mold platform is a T-shaped ejector block. The composite plate is placed in the area enclosed by the ejector blocks. An ejector cylinder 19 is provided at the bottom of the ejector block 18. During molding, the ejector block extends to prevent the shaped tube from being displaced by the expansion pressure. A rubber roller support is installed on the outside of the rubber roller 17, and a rubber roller cylinder 16 is provided at the bottom of the rubber roller support. The cylinder 16 is installed inside the lower mold platform. After molding is completed, the rubber roller cylinder moves upward, causing the composite plate to detach from the lower mold platform. At the same time, the rubber roller rotates, and the composite plate rolls along the rubber roller and moves out of the lower mold platform. When laying tiles or decorative panels on the lower mold table, the rubber roller can assist the robotic arm in laying the tiles in place.

[0046] The control system includes a control circuit consisting of a controller and a photoelectric control switch. The controller is connected to the lifting motor 13, the rubber roller cylinder 16, the ejection cylinder 19 and the walking motor 14, and can complete the operations of intelligent movement of the gantry, automatic brick laying of the lower mold table, synchronous movement of the lifting machine and intelligent demolding of the composite board.

[0047] The following is a further explanation of the working process of the sheet metal forming machine:

[0048] The specifications of the decorative layer, supporting keel, and edge sealing steel plate of the composite panel are determined according to the design requirements and the dimensions of the wall panels and floor slabs. A robotic arm lays the decorative layer tiles onto the surface of the lower mold table, while simultaneously controlling the rubber roller cylinders to eject the rubber rollers to facilitate tile laying. A reinforcing mesh is laid on the tile surface, and a frame consisting of supporting keels and shaped tubes or geometric steel is placed on the reinforcing mesh. The reinforcing mesh and tiles are then placed on top of the frame. The ejection cylinders are activated according to the dimensions of the composite panel, and several ejection blocks extend from the lower mold table to form a mold frame, used to define the position of the shaped tubes, geometric steel, or joints.

[0049] The control circuit activates the travel motor, which moves the gantry frame above the lower mold platform. The control circuit then activates the lifting mechanism, which moves the upper mold 11 downwards until it contacts the tile. The distance between the upper mold and the lower mold platform is the thickness of the wall panel or floor slab. The controller coordinates the synchronous movement of each lifting mechanism to ensure smooth, horizontal movement of the entire upper mold. Flame-retardant polyurethane material is injected between the tiles in the upper and lower molds and cured at 60℃ for 30 minutes. Due to the significant tension generated during the foaming process, the pressing mechanism, locking mechanism, and lifting mechanism jointly bear the tension. After foaming, the lifting mechanism lifts the upper mold, moving the gantry frame above the adjacent lower mold platform for the production of the next composite panel. The rubber roller cylinder pushes the rubber roller out, moving the composite panel off the lower mold platform, thus completing the production of one composite panel. After quality inspection, it is packaged as a finished product.
