Description

Technical Field

[0001] This invention relates to the field of light steel structure building technology, specifically a prefabricated light steel house for new rural construction. Background Technology

[0002] Light steel structure construction originated in North America, initially as a steel alternative to wood structures. New Zealand engineers invented a specialized keel machine, enabling factory-customized production of components (integrated punching, cutting, and bending), driving technological innovation in prefabricated light steel construction. In China, it was initially introduced primarily for temporary buildings, and later gradually applied to permanent new rural housing. Because light steel houses meet the requirements of "low carbon, energy saving, and industrialization," they have become a key technology promoted in new rural construction. With a cold-rolled light steel keel system at its core, it achieves safe, efficient, and low-carbon construction through material innovation, process upgrades, and green technologies. Its technological evolution has consistently focused on solving three major pain points: earthquake resistance, thermal performance, and construction accuracy. Future development will extend towards intelligent monitoring and composite materials.

[0003] The main frame components of the light steel house are made of light steel keel synthesized by cold rolling technology using hot-dip galvanized steel strips, combined with high-strength bolts or welding, and further enhanced by a special tenon and mortise nesting structure to improve the resistance to deformation. The floor and roof are composed of cold-formed thin-walled steel frames with oriented strand board or cement fiberboard. The roof uses composite insulation board with purlins to form a drainage slope. SBS waterproof membrane is used to cover the joints to block thermal bridges and prevent seepage. The interior and exterior walls are made of calcium silicate board or gypsum board, with cavities filled with rock wool or glass wool insulation layers. Air inlets are set at the bottom to form airflow circulation. Tongue and groove overlap is used at the vertical joints to minimize the height difference of the joints, and sealant is injected into the joints to achieve the effect of moisture-proofing.

[0004] In existing light steel frame houses, the construction and assembly process involves manually moving the light steel frames. Multiple workers are needed to support the entire frame for leveling and alignment. Finally, workers must fix the light steel frames with self-tapping screws at fixed points and equal intervals. During the installation of these screws, workers repeatedly adjust the flatness of the light steel frames, ensuring that both ends are aligned horizontally, vertically, and front-back. This requires repeated manual measurements, making the assembly time long and inefficient. If errors occur during the assembly process, gaps will appear, creating cavities in the insulation layer, forming thermal bridges and causing heat loss. Furthermore, rainwater or moisture can easily seep into the joints. The rock wool and glass wool filling the light steel frame absorb moisture, increasing their thermal conductivity and drastically reducing insulation performance. Moreover, misalignment of the steel frame causes uneven stress on the insulation layer, leading to stress concentration in the core material under long-term loads, resulting in cracking and detachment, and ultimately exposing and corroding the steel frame.

[0005] Therefore, the present invention provides a prefabricated light steel house for new rural construction that can quickly level and align light steel frames in multiple dimensions and be quickly installed and spliced. Summary of the Invention

[0006] To address the problems in existing technologies, such as the long time required for splicing and alignment of light steel frames, poor insulation performance due to uneven splicing, and corrosion of the steel frame due to water seepage, which affects the service life of the light steel house, a prefabricated light steel house for new rural construction has been designed.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a prefabricated light steel house for new rural construction, including a light steel frame one, a light steel frame two, and a vertical plate set inside the light steel frame two. The side wall of the light steel frame two is provided with equidistant holes, the side wall of the light steel frame one is provided with a slot, a central rod is fixed at the center of the side wall of the vertical plate, a leveling rod is fixed to the side wall of the vertical plate, a parallel rod is fixed to the side wall of the vertical plate, and a U-shaped groove is provided on the side wall of the leveling rod and the parallel rod. A sleeve is slidably connected inside the U-shaped groove, and a U-shaped clamp is fixed at the outer end of the sleeve. The U-shaped clamp has a first spring fixed to each side wall, and a movable clamping plate fixed to the other end of the first spring. The inner wall of the movable clamping plate has a third inclined surface. The central rod moves the second light steel frame to one side wall of the light steel frame, making the geometric center height of the second light steel frame consistent with that of the first light steel frame. The U-shaped clamp pulls the upper and lower ends of the second light steel frame, making the second light steel frame perpendicular to the first light steel frame and clamping it. At the same time, the movable clamping block is inserted into the slot, making the first light steel frame and the second light steel frame flush and close together. During the movement of the second light steel frame, the first light steel frame and the second light steel frame are first aligned point-to-point vertically through the central rod in three dimensions: up and down, front and back, and left and right. Then, the U-shaped clamp is used to make the first light steel frame and the second light steel frame line-to-line horizontally aligned. Finally, the movable clamping plate is used to make the surfaces of the first light steel frame and the second light steel frame aligned and close together, so that the first light steel frame and the second light steel frame are perpendicularly close to each other in three-dimensional space.

[0008] Furthermore, the outer ends of the center rod and the leveling rod are provided with a first inclined surface, the inner end of the center rod is consistent with the size and shape of the hole and slides inside the hole, and the outer ends of the center rod and the leveling rod are provided with equidistant honeycomb holes.

[0009] Furthermore, a second spring is fixed to the inner wall of the U-shaped clamp, and a washer is fixed to the side wall of the second spring. The outer end of the movable clamp slides through the interior of the slot.

[0010] Furthermore, a handle is fixed to the side wall of the sleeve, and the handle slides inside the U-shaped groove.

[0011] Furthermore, the center rod, leveling rod, and parallel rod all slide inside the hole, and the outer end of the movable plate slides through the inside of the slot.

[0012] Furthermore, a push-pull rod is slidably connected inside the central rod. One end of the push-pull rod is fixed with a locking block located on the side wall of the upright plate, and the other end of the push-pull rod is fixed with a handle located on the outer side wall of the central rod.

[0013] Furthermore, a positioning frame is fixed inside the light steel frame, and a tripod is slidably connected to the side wall of the positioning frame. A shaped groove is opened in the center of the tripod.

[0014] Furthermore, symmetrically placed protrusions are fixed to the outer end of the parallel rod, and the protrusions slide inside the irregular groove.

[0015] Furthermore, the side wall of the irregular groove is provided with an elongated groove, a third spring is fixed inside the elongated groove, a push plate is fixed to the outer end of the third spring, a moving rod is fixed to the side wall of the push plate, the moving rod is located at the center of the third spring and passes through the interior of the elongated groove.

[0016] Furthermore, a fourth spring is fixed inside the positioning frame, and a movable block is fixed to one end of the fourth spring. The movable block slides through the side wall of the positioning frame, and the outer end of the movable block is in contact with the side wall of the push plate.

[0017] The beneficial effects of this invention are: (1) The prefabricated light steel house for new rural construction described in this invention uses a central rod, a leveling rod, and a parallel rod in conjunction with a U-shaped clamp and a slot to first align the light steel frame one and the light steel frame two by points, then by aligning the lines, and finally by automatically aligning and fitting the surfaces perpendicular to each other. The light steel frame one and the light steel frame two are fitted and fixed in six degrees of freedom: up and down, front and back, left and right. As the insertion depth increases, the gap between the central rod and the first inclined surface of the hole gradually decreases, forcibly achieving high-precision vertical correction. At the same time, the U-shaped clamp contacts the side wall of the light steel frame through the second inclined surface, triggering the elastic deformation of the movable plate during movement, and finally embedding into the slot to complete the front and back locking. Three-dimensional leveling can be completed without the need for additional tools, which greatly reduces the dependence on the experience of the operators and realizes simultaneous movement, correction, and fixing assembly, shortening the on-site operation time.

[0018] (2) The prefabricated light steel house for new rural construction described in this invention adopts an equidistant honeycomb hole structure at the outer ends of the central rod and the leveling rod to form a honeycomb-like porous material layout, which gives the connection part a unique mechanical response characteristic. When the light steel frame is subjected to internal stress caused by vibration, impact or temperature deformation during transportation and splicing, the honeycomb hole array can dissipate energy through local buckling and plastic deformation by utilizing its high strength, excellent energy absorption capacity and low density characteristics, preventing stress concentration from being transmitted to the main structure, thereby protecting the main frame from damage. At the same time, the regular hexagonal arrangement has the advantage of isotropic support, which can provide the maximum bending and shear resistance with the minimum material usage.

[0019] (3) The prefabricated light steel house for new rural construction described in this invention adopts a linkage of protrusions, irregular grooves, tripods and springs. The movement of the parallel rod drives the protrusions to slide along the irregular grooves, so that the tripods automatically extend and contact the ground. When it touches the bottom, the fourth spring pushes the moving block to lock the end of the tripod, forming a rigid support. By observing the ground contact status of each support point, the worker can quickly determine whether to add or remove shims. The uniform foundation bearing effectively avoids the risk of structural failure such as local buckling of column bases and cracking of welds. When retracted, the reverse movement automatically unlocks and retracts the legs, reducing the interference of protruding parts on the subsequent wall installation, while lowering the overall center of gravity and enhancing temporary stability.

[0020] (4) The prefabricated light steel house for new rural construction described in this invention adopts the method of retracting the center rod, leveling rod and parallel rod and fixing the upright plate to the inner wall of the light steel frame, so as to transform it into an internal horizontal support component, play the function of secondary structure, provide lateral constraint force, enhance the light steel frame's resistance to lateral displacement, and the mechanical self-locking mechanism of the handle rotation drive block locking is safe and reliable and not easy to loosen. At the same time, the components are completely embedded in the steel frame cavity, which does not affect the construction of the inner and outer walls and maintains a clean appearance.

[0024] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Example: Figures 1-12As shown, the prefabricated light steel frame house for new rural construction of the present invention includes a light steel frame 1, a light steel frame 2, and a vertical plate 4 disposed inside the light steel frame 2. The side walls of the light steel frame 2 have equidistant holes 3. The side walls of the light steel frame 1 have slots 19. A central rod 5 is fixed to the center of the side wall of the vertical plate 4. A leveling rod 6 and a parallel rod 7 are fixed to the side walls of the vertical plate 4. U-shaped grooves 11 are formed on the side walls of the leveling rod 6 and the parallel rod 7. A sleeve 12 is slidably connected inside the U-shaped groove 11. A U-shaped clamp 14 is fixed to the outer end of the sleeve 12. A first spring 16 is fixed to the side wall of each U-shaped clamp 14. A movable clamp 17 is fixed to the other end of the first spring 16. The outer end of the movable clamp 17 slides through the interior of the slot 19. A third inclined surface 18 is formed on the inner wall of the movable clamp 17. The central rod 5 is attached to the central plate 14. As the movable light steel frame 2 moves to the side wall of the light steel frame 1, the geometric center height of the light steel frame 2 and the light steel frame 1 is kept consistent. The U-shaped clamp 14 pulls the upper and lower ends of the light steel frame 2 to make the light steel frame 2 and the light steel frame 1 perpendicular and clamped. At the same time, the movable plate 17 is inserted into the slot 19 to make the light steel frame 1 and the light steel frame 2 flat and close together. During the movement of the light steel frame 2, the light steel frame 1 and the light steel frame 2 are first aligned point-to-point vertically through the central rod 5, then aligned horizontally through the U-shaped clamp 14, and finally aligned surface to surface through the movable plate 17, so that the light steel frame 1 and the light steel frame 2 are perpendicularly close to each other in three-dimensional space.

[0026] In this embodiment, the prefabricated light steel frame 1 is fixed to the foundation anchor bolts with high-strength bolts. When splicing the light steel frame 2 to the light steel frame 1, the contact surfaces of the light steel frame 2 and the light steel frame 1 need to be flush. When moving the light steel frame 2, the outer ends of the center rod 5, leveling rod 6, and parallel rod 7 all pass through the holes 3 of the light steel frame 1. Before the light steel frame 2 is about to be attached to the light steel frame 1, the worker adjusts the position of the U-shaped clamp 14 by using the handle 13, so that the U-shaped clamp 14 rotates 90° in the U-shaped groove 11, making it easy to place the U-shaped clamp 14 horizontally and lock it onto the side wall of the light steel frame 2. At the same time, when the light steel frame 2 is moved, the second inclined surface 15 of the U-shaped clamp 14 is in contact with the side wall of the light steel frame 1, so that the U-shaped clamp 14 on the leveling rod 6 and parallel rod 7 can be aligned with the light steel frame 1 and the light steel frame 1. The upper and lower ends of frame 2 are clamped, while the light steel frame 1 and light steel frame 2 are aligned and fitted in the left and right directions. When the U-shaped clamp 14 moves onto light steel frame 1, the movable plate 17 moves outward under the action of the third inclined surface 18, and the second spring 20 is subjected to compression. When the U-shaped clamp 14 fits light steel frame 1 and light steel frame 2 together, the movable plate 17 moves to the slot 19, and the second spring 20 releases its energy to push the movable plate 17 into the slot 19, thus clamping and fixing light steel frame 1 and light steel frame 2 together. This ensures that light steel frame 2 is aligned with light steel frame 1 in all directions during the movement, making it easy to align and fix light steel frame 1 and light steel frame 2. It also allows operators to use self-tapping screws to position and fix light steel frame 1 and light steel frame 2 together.

[0027] Specifically, the outer ends of the center rod 5 and the leveling rod 6 are provided with a first inclined surface 9. The inner end of the center rod 5 is the same size and shape as the hole 3 and slides inside the hole 3. The outer ends of the center rod 5 and the leveling rod 6 are provided with equidistant honeycomb holes 10. The inner wall of the U-shaped clamp 14 is fixed with a second spring 20. The side wall of the second spring 20 is fixed with a washer 21. The side wall of the sleeve 12 is fixed with a handle 13. The handle 13 slides inside the U-shaped groove 11.

[0028] In this embodiment, when the light steel frame 2 is spliced ​​and moved, the outer ends of the center rod 5, leveling rod 6, and parallel rod 7 all penetrate into the holes 3 of the light steel frame 1. The center rod 5 and leveling rod 6 are attached to the holes 3 through the first inclined surface 9. During the movement, the center rod 5 and leveling rod 6 are increasingly tightly attached to the holes 3 of the light steel frame 1, causing the light steel frame 2 to move and correct vertically during the movement. When the center rod 5 is completely attached to the holes 3, the light steel frame 2 is aligned with the light steel frame 1 in the vertical direction, and the side wall heights of the light steel frame 1 and the light steel frame 2 are consistent. During the movement, the light steel frame 1 and the light steel frame 2, through the multiple honeycomb holes 10 on the surface of the center rod 5 and leveling rod 6, construct a densely arranged positive structure inside the material. The hexagonal perforated units form a lightweight and high-strength buffer energy absorption system. Its core principle is to use the honeycomb porous structure to disperse the load and absorb energy while maintaining extremely low density. This allows the honeycomb holes 10 to absorb and eliminate the negative effects of the generated stress. At the same time, the light steel frame 1 and light steel frame 2 are flush and fitted with each other, which can prevent misalignment of the steel frame during splicing. The gaps formed by misalignment will cause cavities in the insulation layer. Heat will be quickly conducted through the metal frame, forming a thermal bridge effect and causing heat loss. Moreover, uneven joints are prone to seepage of rainwater or moisture. This will cause the thermal conductivity of the rock wool, glass wool and other materials filled inside the light steel frame 1 and light steel frame 2 to increase after absorbing moisture, resulting in a sharp drop in insulation performance. Furthermore, the misalignment of the steel frame will cause uneven stress on the insulation layer. Under long-term load, the stress of the core material will not be concentrated and will crack and fall off, resulting in the steel frame being exposed and corroded.

[0029] Specifically, the center rod 5, leveling rod 6, and parallel rod 7 all slide inside the hole 3. The outer end of the movable plate 17 slides through the inside of the slot 19. The center rod 5 is slidably connected to a push-pull rod 22. One end of the push-pull rod 22 is fixed with a locking block 23, which is located on the side wall of the upright plate 4. The other end of the push-pull rod 22 is fixed with a handle 24, which is located on the outer side wall of the center rod 5.

[0030] In this embodiment, after the light steel frame 1 and light steel frame 2 are leveled, fitted, and fixed, the movable clamping plate 17 is pulled outward, causing the center rod 5, leveling rod 6, and parallel rod 7 to pull the upright plate 4 back onto the light steel frame 2. While retracting the center rod 5, leveling rod 6, and parallel rod 7, the handle 13 is moved within the U-shaped groove 11, and the U-shaped clamp 14 is rotated 90° to retract into the interior of the light steel frame 2. During this movement, the protrusion 25 on the parallel rod 7 engages with the irregular groove 26, retracting the tripod 8 into the interior of the light steel frame 1. Simultaneously, the upright plate 4 is retracted into the light steel frame 1. When plate 4 moves to fit against the inner wall of light steel frame 2, the center rod 5, leveling rod 6, and parallel rod 7 retract into the interior of light steel frame 2. By rotating handle 24, the locking block 23 fixes the upright plate 4 to light steel frame 2. At the same time, the rotated handle 24 fits against the inner wall of light steel frame 1 and interlocks with the hole 3, so that the center rod 5, leveling rod 6, and parallel rod 7 retract into the interior of light steel frame 2 to fix light steel frame 2 and light steel frame 1. It can also provide lateral support force to the interior of light steel frame 2, strengthening the supporting function of light steel frame 2.

[0031] Specifically, a positioning frame 31 is fixed inside the light steel frame 1. A tripod 8 is slidably connected to the side wall of the positioning frame 31. A shaped groove 26 is opened in the center of the tripod 8. Symmetrically placed protrusions 25 are fixed to the outer end of the parallel rod 7. The protrusions 25 slide inside the shaped groove 26. A long groove 27 is opened in the side wall of the shaped groove 26. A third spring 30 is fixed inside the long groove 27. A push plate 28 is fixed to the outer end of the third spring 30. A moving rod 29 is fixed to the side wall of the push plate 28. The moving rod 29 is located in the center of the third spring 30 and passes through the inside of the long groove 27. A fourth spring 32 is fixed inside the positioning frame 31. A moving block is fixed to one end of the fourth spring 32. The moving block slides through the side wall of the positioning frame 31. The outer end of the moving block is in contact with the side wall of the push plate 28.

[0032] In this embodiment, the protrusion 25 at the outer end of the parallel rod 7 pushes the tripod 8 outward along the positioning frame 31. The protrusion 25 moves within the irregular groove 26, causing the tripod 8 to move downward under the action of the irregular groove 26 while the parallel rod 7 moves outward, thus engaging the bottom of the tripod 8 with the bottom of the light steel frame 1. After aligning and fitting the light steel frame 1 and the light steel frame 2, based on the contact between the tripod 8 and the ground, when the tripod 8 moves to its lowest point, the moving block moves outward under the thrust provided by the fourth spring 32 to the top of the moving end of the tripod 8 to fix the tripod 8. This allows the operator to quickly adjust and increase the bottom of the light steel frame 1 and the light steel frame 2. The shim 21 is used to make the light steel frame 1 and the light steel frame 2 flush with the ground. The flushness between the light steel frame 1 and the light steel frame 2 with the ground can avoid uneven stress at the bottom of the steel column of the light steel frame, and the local stress exceeding the design value, which may cause the component to twist or the weld to crack. At the same time, it can improve the wind resistance and earthquake resistance. When the tripod 8 is retracted, the protrusion 25 moves into the irregular groove 26. When the protrusion 25 moves, it pushes the moving rod 29 to move, which in turn pushes the push plate 28 to move, so that the push plate 28 pushes the moving block into the interior of the positioning frame 31, which facilitates the tripod 8 to move upward and retract into the interior of the light steel frame 1, strengthens the weight at the bottom of the light steel frame 1, lowers the center of gravity, and increases the stability of the light steel frame 1.

[0033] Working principle: In the construction of light steel frame houses, the foundation is first tested, leveled, and a trench is dug. Then, a strip foundation or a solid concrete slab is placed in the trench, a concrete cushion layer is poured, and anchor bolts are pre-embedded in the concrete base layer. The concrete layer is then smoothed. The prefabricated light steel frame 1 is fixed to the foundation anchor bolts with high-strength bolts. The worker adjusts the position of the U-shaped clamp 14 by using the handle 13, so that the U-shaped clamp 14 rotates 90° within the U-shaped groove 11, aligning the center rod 5, leveling rod 6, and parallel... The outer ends of rods 7 all penetrate the holes 3 of the light steel frame 1. The center rod 5 and the leveling rod 6 connect the light steel frame 2 and the light steel frame 1 through the first inclined surface 9 and the hole 3. The U-shaped clamp 14 and the movable locking block 23 ensure that the side walls of the light steel frame 1 and the light steel frame 2 are of the same height and are flush and fitted in all directions, making it easy for operators to fix the light steel frame 1 and the light steel frame 2 with self-tapping screws. When the light steel frame 2 moves, the protrusion 25 at the outer end of the parallel rod 7 pushes the tripod 8 along the path. Positioning frame 31 is moved to the bottom of light steel frame 1 and engaged. After aligning and fitting light steel frame 1 and light steel frame 2, the workers can quickly adjust the floor mat joists to make light steel frame 1 and light steel frame 2 flush with the ground by observing the fit between the tripod 8 and the ground. Then, the movable clamping plate 17 is pulled outward to move the upright plate 4 into light steel frame 2, and the center rod 5, leveling rod 6, and parallel rod 7 are retracted. The handle 13 is then turned to retract the U-shaped clamp 14 into light steel frame 2. During the movement, the protrusion 25 on the parallel rod 7 retracts the tripod 8 into the interior of the light steel frame 1. When the center rod 5, leveling rod 6, and parallel rod 7 are retracted into the interior of the light steel frame 2, the handle 24 is turned so that the locking block 23 fixes the upright plate 4 to the light steel frame 2. This retraction of the center rod 5, leveling rod 6, and parallel rod 7 into the interior of the light steel frame 2 fixes the light steel frame 2 and the light steel frame 1, providing lateral support to the interior of the light steel frame 2 and strengthening its supporting function.
