[0069] To make the technical problems, technical solutions and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0070] Single-story lightweight panel structure houses, such as Figures 1 to 6 As shown, the house includes a foundation, walls 200 fixedly installed on the foundation, and a light steel roof 400 fixedly installed on the top of the walls 200.

[0071] (a) Foundation structure:

[0072] The foundation is constructed from precast foundations 100, each including a foundation slab 101 and a continuous clamp 102 fixed along the length of the top surface of the foundation slab 101. The continuous clamp 102 is a U-shaped shell formed by the enclosing of its two sides and bottom. The foundation slab 101 is precast concrete, with a thickness of 10-30 cm, a width of 20-50 cm, and a length selected based on the building design and principles of ease of transportation and installation. Several screw holes are provided on both sides of the continuous clamp 102 for subsequently inserting screws to fix the wall panels.

[0073] The first method of fixing the base plate 101 to the through-length clip 102 is as follows: Figure 7 and Figure 8 As shown, a groove is formed along the length of the top of the base plate 101. Several bolts 103 are embedded at intervals along the length of the groove, with the length of the bolts 103 extending out of the groove less than the depth of the groove, to prevent the bolts 103 from interfering with the installation of the wall panel in the continuous clamp 102. The continuous clamp 102 has through holes along its length corresponding to the positions of the bolts 103. The through holes of the continuous clamp 102 pass through the bolts 103, and nuts 104 are placed on the bolts 103 to fix the continuous clamp 102 to the base plate 101. To ensure waterproofing and leak prevention at the connection between the base plate 101 and the continuous clamp 102, flexible tape 105 is placed between the continuous clamp 102 and the base plate 101. The anchorage length of the bolts 103 in the base plate 101 is 3-5 cm to ensure the fixing strength between the bolts 103 and the base plate 101.

[0074] The second method of fixing the base plate 101 to the through-length clip 102 is as follows: Figure 9 and Figure 10 As shown, an anchor 106 is fixedly installed at the bottom of the full-length clamp 102, and the anchor 106 is embedded in the base plate 101. The anchor 106 and the full-length clamp 102 can be fixed by welding, bolting, or as an integrally formed structure. In this embodiment, the anchor 106 is an inverted T-shaped structure, including a horizontal plate 1061 and a vertical plate 1062 fixed to the horizontal plate 1061 and perpendicular to the horizontal plate 1061. The vertical plate 1062 is connected to the bottom end face of the full-length clamp 102. When preparing the precast foundation 100, the full-length clamp 102 is directly connected to the base plate 101, which improves production efficiency. The base plate 101 is internally provided with longitudinal and transverse reinforcing bars to enhance the strength of the base plate 101.

[0075] The foundation slab 101 is equipped with ground anchors, which can be any type of expansion bolt, anti-reverse bolt, or anti-reverse ball. By using ground anchors, the main structure of the house can be made particularly stable, thereby improving the safety factor.

[0076] (ii) Structure of the 200mm wall:

[0077] The wall 200 is entirely composed of spliced ​​wall panels, with the bottom ends of the wall panels secured in continuous clamps 102. In a preferred embodiment, fiberglass mesh 700 is provided on both the inner and outer sides of the wall panel splicing locations. Cement mortar is sprayed onto both the inner and outer sides of the wall panels to form a protective layer 300. Both the continuous clamps 102 and the wall panels are encased within the protective layer 300. The combination of the fiberglass mesh 700 and the protective layer 300 enhances the connection strength between the wall panels, resulting in good overall integrity of the wall 200 and high construction efficiency. The protective layer 300 has a thickness of 8mm to 12mm, ensuring it meets the strength requirements of the actual wall structure.

[0078] The wall panel is rigidly connected to the base plate by a bottom-embedded fixing device (continuous clip), and the connection strength is relatively high.

[0079] The wall 200 includes a front wall, a back wall, side walls and an interior wall. The wall 200 is provided with a door opening and / or a window opening. The side walls and the interior walls parallel to the side walls are formed by splicing multiple trapezoidal wall panels. The height of the top of the side walls gradually decreases from the middle to the two sides of the front wall and the back wall to form a ridge.

[0080] The structure of the wall panel is as Figures 11 to 14 shown. The wall panel is a modular wall panel, which includes a wall panel with a window structure ( Figure 13 ), a wall panel with a door structure ( Figure 14 ), a trapezoidal wall panel ( Figure 12 ), and a rectangular standard wall panel ( Figure 11 ). The wall panel with a window structure is pre-designed with a window opening, and the wall panel with a door structure is pre-designed with a door opening. The door frame and window can be directly installed without secondary construction, saving materials and simplifying the subsequent decoration construction of the house building. The trapezoidal wall panel is used to form the side wall. The trapezoidal wall panel under the ridge has the highest height, and the height of the trapezoidal wall panels from the middle of the house to the two sides of the front wall and the back wall gradually decreases, and the top inclined surfaces of two adjacent trapezoidal wall panels are connected. The rectangular standard wall panel can be used in the interior wall or between the wall panel with a window structure and / or the wall panel with a door structure to extend the wall. The wall panel with a window structure can form a window on one wall panel or two wall panels can be joined to form a window. In the present utility model, the latter is adopted, and the process of manufacturing the wall panel with a window structure is convenient.

[0081] The wall panel includes a light steel keel frame 201 and a concrete filling part 202 arranged inside the light steel keel frame 201. The concrete filling part 202 is internally provided with a fiberglass mesh cloth inside the wall panel, near the inner and outer surfaces of the concrete filling part 202; the fiberglass mesh cloth inside the wall panel plays a role in preventing the concrete filling part 202 from cracking. The light steel keel frame 201 is a frame structure formed by connecting steel sections. The steel sections are connected by connecting pieces and screws. A steel strip 204 is arranged between two adjacent steel sections to enhance the stability of the light steel keel frame 201. The structure of the steel section can be one of C-shaped steel, H-shaped steel, and I-shaped steel structures, or other forms of steel structures such as steel pipes can be selected. The light steel keel frame 201 is in the shape of "mouth" or "day". When the light steel keel frame 201 is in the shape of "day", at least one through hole is formed through the internal transverse steel section. When preparing the wall panel, the concrete slurry can penetrate up and down, ensuring the integrity of the wall panel.

[0082] The concrete filling section 202 is formed by the curing of materials such as foamed concrete and polystyrene particle concrete. The wall panel is 8-12 cm thick, which can ensure the strength of the wall 200 and the thermal insulation effect of the house, while the production cost is relatively low.

[0083] The wall panel is produced using a vertical mold process. A grouting hole 205 is provided on one side of the light steel keel frame 201. Templates are set on both sides of the open part of the light steel keel frame 201. Concrete is poured into the inner cavity between the templates through the grouting hole 205 on the side. After curing, the wall panel is prepared. The production process is simple and efficient, and the space utilization rate of the factory is high.

[0084] Depending on the building design, the connections between wall panels can include butt joints, L-shaped right-angle joints, and T-shaped joints. For example... Figure 15 As shown, when the wall panels are joined flush, at least one flat connector 500 is installed in the height direction at the joint position on the inner and outer sides of the two wall panels. The flat connector 500 and the two wall panels are fixed with self-tapping screws; for example... Figure 16 and Figure 17 As shown, when the wall panels are connected at an L-shape at a right angle, at least one U-shaped connector 600 is fixedly installed in the height direction of the side end of one of the wall panels, and the side end of the other wall panel is inserted into the U-shaped connector. The U-shaped connector 600 and the two wall panels are fixed by self-tapping screws; Figure 18 and Figure 19 As shown, when the three wall panels are connected in a T-shape, the end faces of two wall panels are connected, and at least one flat plate connector 500 is provided on the outer side of each of the two wall panels in the height direction. The flat plate connector 500 and the two wall panels are fixed with self-tapping screws. At least one U-shaped connector 600 is provided at the inner connection position of the two wall panels. The side end of the third wall panel is inserted into the U-shaped connector 600, and the U-shaped connector 600 and the three wall panels are fixed with self-tapping screws.

[0085] Adjacent wall panel units are assembled using standardized connecting components, which include one or a combination of flat plate connectors and U-shaped connectors, thereby constructing a three-dimensional spatial constraint system to achieve a self-stabilizing structure for the wall panels.

[0086] (III) Structure of 400mm Light Steel Roof:

[0087] The light steel roof 400 includes a ridge purlin 401 fixedly installed at the top of the interior wall, an eaves purlin 402 on one side of the front wall, a front secondary purlin 403 connecting the ridge purlin 401 and the eaves purlin 402, and a back secondary purlin 404 between the ridge purlin 401 and the back wall. Several front secondary purlins 403 are arranged in parallel and equidistantly between the two side walls, and several back secondary purlins 404 are arranged in parallel and equidistantly between the two side walls.
