Technical Field

[0001] This invention relates to the field of building construction, and specifically to a prefabricated column structure house. Background Technology

[0002] Traditional construction methods for building houses have drawbacks such as low construction efficiency and high labor intensity. At present, some prefabricated houses have emerged, which can effectively shorten the construction period by splicing various templates. However, the stability of the spliced ​​houses is poor and the overall strength is often difficult to guarantee. Therefore, there is a need to propose a prefabricated housing system that can improve the stability of the housing while ensuring that the prefabrication method shortens the construction period. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a prefabricated column structure house and prefabricated wall panels for assembling and splicing to form the walls of the house. The prefabricated wall panels include a wall template frame, and a pouring cavity is provided inside the wall template frame for pouring concrete slurry. A pouring frame is provided inside the pouring cavity. When the prefabricated wall panels are assembled, the pouring cavities of adjacent prefabricated wall panels are interconnected and the adjacent pouring frames are interconnected. And a prefabricated roof slab, on which a truss is provided, and the prefabricated roof slab can be detachably installed on top of the wall formwork frame.

The prefabricated wall panels that are adjacent in the horizontal direction are connected to each other by the second structural rod.

[0005] Preferably, the wall formwork frame further includes a base, the base including panels located on the inner and outer sides of the wall formwork frame respectively and a sealing strip located between the two panels, the first cavity and the second cavity are both located inside the two panels; the sealing strip is used to seal the gap between the two panels, and the sealing strip is provided with pouring holes at the parts corresponding to the first cavity and the second cavity.

[0006] Preferably, the first structural rod is a steel bar, the second structural rod is a threaded rod, and a threaded sleeve is provided at the end of the second structural rod. The second structural rods of adjacent prefabricated wall panels are connected to each other through the threaded sleeve.

[0008] Preferably, the corner connector is a hollow structure, the interior of the corner connector is connected to the interior of the second cavity, and a third structural rod passes through the corner connector.

[0009] Preferably, the room also includes a floor slab and a staircase. The floor slab is arranged parallel to the bearing surface and the prefabricated roof slab. The floor slab divides the room between the bearing surface and the prefabricated roof slab into several floors. The first cavity is fixedly installed between the bearing surface and the floor slab and between the floor slab and the prefabricated roof slab. Different floors are connected by the staircase.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Figure 1 This is a schematic diagram of the overall structure of the prefabricated column structure house provided in the embodiment of the present invention.

[0018] like Figure 1 As shown, the prefabricated column structure house provided in this embodiment of the invention includes prefabricated wall panels 1, prefabricated roof panels 2, and corner connectors 3. The prefabricated wall panels 1 form the walls of the main body of the house, and the corner connectors 3 are used to connect the prefabricated wall panels 1 at the corners. The prefabricated roof panels 2 are installed on the top of the prefabricated wall panels 1 as the roof of the house. If the house is a multi-story structure, each floor is separated by floor slabs 4. Through the above structure, the house structure in this embodiment can effectively shorten the construction period and reduce the labor intensity during construction, which is conducive to its widespread use.

[0019] Figure 2 This is a structural schematic diagram of the wall formwork skeleton of the prefabricated column structure house provided in the embodiment of the present invention; Figure 3 This is a partial schematic diagram of the first structural rod and the second structural rod of the prefabricated column structure house provided in an embodiment of the present invention; Figure 4 This is a schematic diagram of the assembled wall template skeleton of the prefabricated column structure house provided in the embodiment of the present invention.

[0020] like Figures 2 to 4As shown, this embodiment of the invention provides a prefabricated column structure house, including prefabricated wall panels 1 and prefabricated roof panels 2. The prefabricated wall panels 1 include a wall formwork frame 11, which includes an internal casting cavity. A casting frame is provided inside the casting cavity. When the prefabricated wall panels are assembled into a wall surface, the casting cavities of the prefabricated wall panels 1 of the entire wall surface are interconnected, and the casting frames inside the casting cavities are interconnected, so that the casting cavities and casting frames of the entire wall surface are cast as a whole, which can effectively improve the integrity and stability of the wall surface. A truss is provided on the prefabricated roof panel, which can effectively improve the strength of the roof panel. In this way, it can achieve the effect of rapid construction of prefabricated structure and ensure that the house has good stability.

[0021] like Figure 2 and Figure 3 As shown, the casting cavity includes a first cavity 111 and a second cavity 112. The first cavity 111 is fixedly installed between the bearing surface of the building and the prefabricated roof slab 2. The second cavity 112 penetrates and extends to both ends of the first cavity 111 in the radial direction. Both the second cavity 112 and the first cavity 111 are hollow structures. The casting frame includes a first structural rod 1111 and a second structural rod 1121 arranged in the first cavity 111 and the second cavity 112 respectively. A connecting bracket 114 is provided at the end of the second structural rod 1121 in the horizontal direction. Adjacent wall formwork skeletons 11 are connected to each other through the connecting bracket 114. like Figure 2 and Figure 4 As shown, both the first cavity 111 and the second cavity 112 are hollow cylindrical structures with first structural rods 1111 and second structural rods 1121 arranged inside. When the wall assembled from the wall template skeleton 11 is poured, the first cavity 111 and the second cavity 112 serve as forming cavities for the concrete slurry. Vertical concrete columns (i.e., the concrete in the first cavity 111) and horizontal concrete columns (i.e., the concrete in the second cavity 112) are formed within these forming cavities. The vertical and horizontal concrete columns are integrally formed and cast together with the first structural rods 1111 and the second structural rods 1121, thereby forming a crisscrossing mesh of reinforced concrete (structural rods) within the wall, which can significantly improve the load-bearing capacity and shear resistance of the prefabricated wall.

[0022] Among them, the first structural rod 1111 and the second structural rod 1121 are preferably steel bars. Steel bars are standard components widely used in construction and are easier to produce or purchase. In some other embodiments, the structural rods can also adopt other rod structures with excellent mechanical strength, which will not be elaborated here.

[0023] like Figure 2As shown, the number of first structural rods 1111 in each first cavity 111 and the number of second structural rods 1121 in each second cavity 112 are preferably two. The two first structural rods 1111 are arranged radially spaced within the first cavity 111. This results in higher strength of the vertical concrete column structure after casting. Furthermore, the connection between the two first structural rods 1111 and the two second structural rods 1121 between the vertical and horizontal concrete columns enhances the overall integrity of the concrete columns, thereby increasing the strength of the prefabricated wall. In some other embodiments, the number of first structural rods 1111 in the first cavity 111 and the number of second structural rods 1121 in the second cavity 112 can also be other, which is not specifically limited here.

[0024] In one preferred embodiment, the second structural rod 1121 is a threaded rod, and the connecting bracket 114 can be adopted as follows: Figure 3 The structure described above includes a connecting bracket 114 connected to the end of the second structural rod 1121. The connecting bracket 114 is generally elongated and its two ends are respectively fixedly connected to two second structural rods 1121 in the same second cavity 112. The connecting bracket 114 has a connecting hole 1141 that mates with the threaded rod of the second structural rod 1121. A threaded sleeve (not shown in the figure) is also fitted onto the end of the second structural rod 1121. Adjacent wall template frames 11 are fixedly connected to each other through the mating of the corresponding second structural rod 1121 and the threaded sleeve. Or, such as Figure 3 As shown, in addition to the connection holes 1141 on both sides that match the second structural rod 1121, the connecting bracket 114 also has an additional connection hole in its middle. The adjacent wall formwork skeleton 11 can also be fixedly connected by setting screws between the connection holes 1141 in the middle of the corresponding connecting bracket 114. The connection method of the adjacent wall formwork skeleton 11 can be adjusted according to the actual situation, which will not be elaborated here.

[0025] like Figure 3As shown, the first structural rod 1111 and the second structural rod 1121 are pre-connected by a pre-connector 115. The pre-connector 115 has pre-connection holes that match the first structural rod 1111 and the second structural rod 1121. After the pre-connector 115 is fitted onto the first structural rod 1111 and the second structural rod 1121, it ensures that the structural rods will not move relative to the second cavity, the first cavity, etc., during the pouring of the wall formwork skeleton 11, thus ensuring the stability of the pouring. Furthermore, after the concrete structure is formed, the connection between the first structural rod 1111 and the second structural rod 1121 via the pre-connector 115 enhances the integrity of the concrete structure and increases the strength of the wall surface. The specific connection method between the first structural rod 1111 and the second structural rod 1121 can be adapted to construction requirements and will not be elaborated here.

[0026] Furthermore, regarding the connection method between the prefabricated wall panel 1 and the bearing surface (i.e., the foundation), connection holes for inserting the first cavity 111 can be pre-set on the bearing surface. When the prefabricated wall panel 1 is assembled, the first cavity 111 located at the bottom is embedded in the connection hole. When concrete is poured, the first cavity 111 and the bearing surface are poured as one, which can ensure the connection strength between the first cavity 111 and the bearing surface, thereby ensuring the stability of the building. In addition, other connection methods can also be used to connect the prefabricated wall panel 1 and the bearing surface, which will not be elaborated here.

[0027] like Figure 2 As shown, in one preferred embodiment, each wall template frame 11 includes at least two adjacent first cavities 111 and at least three second cavities 112 spaced axially on the first cavities 111. The first cavities 111 and the second cavities 112 in each wall template frame 11 are an integral structure. In this way, each wall template frame 11 can form at least one "well" shaped concrete grid structure after pouring, which can improve the strength of each wall template frame 11. Multiple concrete grid structures are interconnected and poured into one piece through the above-mentioned connecting brackets, which can further improve the strength of the formed prefabricated wall panel 1.

[0028] Figure 5 This is a schematic diagram of the base structure of the wall template skeleton of the prefabricated column structure house provided in the embodiment of the present invention.

[0029] like Figure 2 as well as Figure 5As shown, in one preferred embodiment, the wall formwork frame 11 further includes a base 113. The base 113 includes an outer panel 1131, an inner panel 1132 located on the inner and outer sides of the wall formwork frame, and a sealing strip 1133 located between the two panels. The first cavity 111 and the second cavity 112 are both located inside the two panels. The sealing strip 1133 is used to seal the gap between the two panels, and pouring holes 1134 are provided on the sealing strip 1133 at the positions corresponding to the first cavity and the second cavity. The first cavity 111 is enclosed by the base 113. The system includes a second cavity 112 and a sealing strip 1133, which allows concrete slurry to enter the first cavity 111 and the second cavity 112 through the pouring hole 1134 during pouring, thus preventing a large amount of concrete from accumulating outside the cavity of the column and causing waste. Furthermore, a sealing structure can be provided between adjacent pouring holes 1134. For example, a sealing ring groove can be provided on the outside of each pouring hole 1134 to accommodate a sealing ring. When adjacent wall formwork frames 11 are fitted together, the adjacent pouring holes 1134 are sealed and connected through the sealing ring groove and the sealing ring, which can prevent concrete slurry from leaking out.

[0030] In addition, filling materials such as foam or sponge can be placed inside the two panels of the base 113 and the gap formed by the first cavity 111 and the second cavity 112 to give the wall template skeleton 11 a certain thermal insulation performance.

[0031] The prefabricated roof slab 2 may include a base plate on which a truss is provided. The truss increases the strength of the roof slab, eliminating the need for workers to lay purlins. After the roof frame is erected, the roof slab can be laid directly. In addition, the roof slab may be provided with a steel bar sleeve that mates with the first cavity 111. The steel bar sleeve can extend into the first cavity 111. In this way, when the wall surface of the prefabricated wall slab 1 is poured, the steel bar sleeve of the prefabricated roof slab 2 can be cast as a whole with the prefabricated wall slab 1, further improving the overall integrity of the building. In some other embodiments, the specific connection method between the prefabricated roof slab and the prefabricated wall slab can also refer to some corresponding solutions in the prior art, such as interlocking, screw connection, or welding between the prefabricated roof slab and the prefabricated wall slab.

[0032] In one preferred embodiment, a corner connector is also included. The corner connector is used to connect adjacent wall formwork frames 11 at the corner of the building. The corner connector has at least two connecting surfaces, and the connecting surfaces are provided with connecting parts for cooperating with the wall formwork frames 11. The connecting parts can cooperate with the second cavity 112 of the wall formwork frame 11, or with the second structural rod 1121 or connecting bracket 114, etc. The specific connection method between the connecting surface of the corner connector and the wall formwork frame 11 can be referred to the connection method between adjacent wall formwork frames 11, which will not be elaborated here.

[0033] In one preferred embodiment, the corner connector is a hollow structure and its interior is connected to the interior of the second cavity 112. A third structural rod is provided inside the corner connector. In this way, when the prefabricated wall is poured, the wall template frame 11, the corner connector and the third structural rod can be poured into one piece, which can effectively improve the structural strength of the wall at the corner and improve the overall integrity and stability of the building structure.

[0034] Furthermore, a second structural rod 1121 can be set within the wall formwork frame 11 adjacent to the corner connector, protruding from the second cavity 112 and extending into the interior of the corner connector. During pouring, the concrete column formed inside the corner connector is poured together with these second structural rods 1121, further enhancing the structural strength of the wall at the corner.

[0035] In one preferred embodiment, the house is a multi-story building, and the house structure also includes floor slabs and stairs. The floor slabs are set parallel to the bearing surface and the prefabricated roof slab. The floor slabs divide the house between the bearing surface and the prefabricated roof slab into several floors. Prefabricated wall panels 1 are fixedly installed between the bearing surface and the floor slab (first floor) and between the floor slab and the prefabricated roof slab (second floor and other floors). Different floors are connected by a drop structure.

[0036] Among them, the floor slab can be a precast truss floor slab, specifically a floor slab spliced ​​with steel trusses. During the actual construction, when assembling the floor slab and the prefabricated wall panel 1, the steel truss of the floor slab is pre-fixed to the first structural rod 1111 in the first cavity 111. After the house is poured, the steel truss floor slab and the prefabricated wall panel 1 are poured into one piece, and the resulting concrete structure has the connection between the steel truss and the first structural rod 1111, which can improve the integrity of the floor slab and the prefabricated wall panel 1 and the stability of the house. In this design, a floor slab can be installed to separate the prefabricated wall panels 1 on different floors. In this case, a pouring hole should be provided on the floor slab at the position corresponding to the first cavity 111 for connecting the prefabricated wall panels 1 on different floors and for the subsequent flow of concrete slurry. Alternatively, the prefabricated wall panels 1 on different floors can be arranged to be continuous vertically, with the floor slab embedded in a ring structure formed by the prefabricated wall panels 1. In short, it should be ensured that the steel reinforcement structure in the floor slab and the first structural rod 1111 and the second structural rod 1121 of the prefabricated wall panel 1 are staggered. This will improve the integrity of the floor slab and the wall when pouring the prefabricated wall panels 1, and ensure the structural strength.

[0037] The staircase can be a cast-in-place concrete staircase, which is cast together with the floor slab and prefabricated wall panel 1. Alternatively, a prefabricated staircase can be used, which is installed in the corresponding position in the house after the other structures of the house are cast. For the specific structure and installation method of the staircase, please refer to the relevant solutions in the existing technology, which will not be elaborated here.

[0038] In one preferred embodiment, the positions of the first cavities 111 between different floors correspond one-to-one, and the same first structural rod 1111 passes through the corresponding first cavities 111 in different floors, or the first structural rods 1111 in the corresponding first cavities 111 between different floors are fixedly connected as one unit. In this way, when the building structure is poured, the prefabricated wall panels 1 of different floors are poured as one unit through the first cavities 111, and the prefabricated wall panels 1 of different floors are connected as one unit through the first structural rods 1111, which can improve the integrity of the prefabricated wall panels 1 of different floors, thereby improving the stability of the building. Prefabricated column structure houses are formed by overlapping floor slabs, prefabricated wall panels, and corner connectors. The internal cavities of the floor slabs, prefabricated wall panels, and corner connectors are interconnected, and the internal steel bars (structural rods) form a three-dimensional mesh structure. During pouring, an integral reinforced concrete structure is formed, which can improve the integrity of the house. In actual pouring, the concrete slurry only enters the first cavity, second cavity, etc., rather than filling the entire wall surface, which can also save materials. At the same time, since the entire house only needs to be assembled on the construction site after the prefabricated floor slabs, wall panels, and corner connectors are assembled at the factory, the overall construction period can be significantly reduced, making it easy to promote and use.

[0039] In one preferred embodiment, the prefabricated wall panel 1 has multiple specifications. The difference between the different specifications of the prefabricated wall panel 1 is that some prefabricated wall panels 1 have clearance holes, and the clearance holes of adjacent prefabricated wall panels 1 are spliced ​​together to form door and window installation holes 5. Furthermore, some prefabricated wall panels 1 can also be set to have a lower vertical height than other prefabricated wall panels. These lower prefabricated wall panels are used to cooperate with the clearance holes of other prefabricated wall panels to form door and window installation holes 5. For other through holes that need to be made in the wall, such as pipe holes and wire holes, the smaller holes can be made directly in the gap between the adjacent first cavity 111 and second cavity 112, while the larger holes can be formed by splicing together the prefabricated wall panels 1 of different specifications mentioned above. In addition, during the pouring process, the first and second cavities that cannot be connected to other first or second cavities due to the setting of clearance holes or due to the low height should be sealed to prevent concrete slurry from leaking out from the openings of these cavities.

[0040] Figure 6a , Figure 6b and Figure 6c This is a schematic diagram of another type of prefabricated wall panel provided in an embodiment of the present invention for a prefabricated column structure house.

[0041] like Figure 6a As shown, in one preferred embodiment, the base 113 of the wall template frame 11 of the prefabricated wall panel 1 is integrally formed with the pouring cavity. That is, the base 113 itself has a first cavity 111 and a second cavity 112 inside, which are used to install the first structural rod 1111 and the second structural rod 1121. When concrete or other slurry is poured in the pouring cavity, a concrete wall 14 can be formed.

[0042] The matrix 113 can be prepared by molding methods such as extrusion, casting, or compression. For example, the matrix 113 can be prepared by extrusion, and the cross-section of the extrusion die is... Figure 6a The top section of the substrate 113 allows the substrate 113 to be extruded along its length and has multiple first cavities 111 extending along the length. Then, the long strip-shaped substrate 113 is cut to a predetermined length and several second cavities 112 are processed in the width direction of the substrate 113 by milling or other means, thus completing the preparation of a substrate 113. In this way, the production efficiency of the wall template frame 11 can be effectively improved, and it can be widely used in some construction scenarios with large building areas.

[0043] like Figure 6b and Figure 6c As shown, in one preferred embodiment, a wire mesh 15 can also be laid in the casting cavity. The wire mesh 15 is set to fit the inner wall of the casting cavity, and the wire mesh 15 has openings for the passage of structural rods and for the flow of casting slurry. In this way, after the casting is completed in the casting cavity, the formed concrete wall 14 has the connection and support of the wire mesh 15 inside, which can further improve the strength of the prefabricated wall panel 1.

[0044] Figure 7 This is a schematic diagram of the prefabricated wall panel structure of the prefabricated column structure house provided in the embodiment of the present invention.

[0045] like Figure 7 As shown, in one preferred embodiment, the prefabricated wall panel 1 further includes an exterior wall component 12 and an interior wall component 13. The exterior wall component 13 includes an insulation layer and an exterior decorative surface layer arranged sequentially along the outer side away from the wall template frame. The insulation layer, the exterior decorative surface layer, and the wall template frame 11 are sequentially fixedly connected by adhesive and / or mechanical connection. The interior wall component includes an interior decorative surface layer, which is fixedly connected to the inner side of the wall template frame 11 by adhesive and / or mechanical connection.

[0046] The exterior wall components 12 and interior wall components 13 can be installed on the wall formwork frame 11 before pouring. This allows the wall formwork frame 11, exterior wall components 12, and interior wall components 13 to be prepared and assembled at the factory or other production site. Once at the construction site, only the prefabricated wall panels 1 need to be assembled to form the wall surface, and the floor slabs, prefabricated roof slabs, corner connectors, etc., before pouring can be carried out. This can effectively shorten the construction period, and the final house will have interior and exterior decorative surfaces and insulation layers, which can effectively save economic and time costs during subsequent decoration. Alternatively, the exterior wall components 12 and interior wall components 13 can be installed on the wall formwork frame 11 after pouring. This can ensure the aesthetics of the exterior wall components 12 and interior wall components 13 and prevent concrete slurry from adhering to the decorative surface of the wall during the pouring process.

[0047] It should be noted that the specific composition and connection method of the interior wall components and exterior wall components listed above are only used to illustrate the technical solution of the present invention. In actual production and use, other decorative panels and other structures can also be set on the wall template frame 11. For example, in order to improve the heat preservation / insulation effect of the house, an insulation layer can also be set in the interior wall component 13, etc., which will not be elaborated here.

[0048] Figure 8 and Figure 8b This is a schematic diagram of another construction method for prefabricated column structure houses provided in an embodiment of the present invention.

[0049] like Figure 8a As shown, in one preferred embodiment, the walls of a prefabricated column structure house can be initially constructed using the first cavity 111 and the second cavity 112. That is, the wall template frame 11 only includes... Figure 8b The cast-in-place frame 110 shown specifically includes a first cavity 111, a second cavity 112, and internal first structural rods 1111, second structural rods 1121, and corresponding structural rod connectors, etc. After sealing the openings of the cavities such as doors and windows, the cast-in-place frame is then constructed. Figure 8a Concrete is poured into the cavity of the skeleton structure of the column structure house shown to form a stable foundation wall structure. Then, decorative components such as inner and outer wall panels or auxiliary reinforcing components such as base 113 are installed on the foundation wall structure. In this way, when building a modular house, there is no need to install other additional components on the cast-in-place frame 110. On the one hand, the assembled prefabricated wall panels are lighter, and the overall construction process from component delivery to house assembly and casting is shorter. After casting, it is also more convenient to install decorative panels on the structurally stable cast-in-place frame 110. On the other hand, when actually assembling and installing the cast-in-place frame 110, the cast-in-place frame 110 and its internal structural rods and connectors are exposed to the outside, and the weight of a single cast-in-place frame 110 is smaller. It is easier for construction workers to assemble adjacent cast-in-place frames 110, thus improving the convenience of construction and installation.

[0050] In addition, Figure 8b In the embodiment shown, the casting frame 110 is generally in the shape of a grid, that is, it includes two vertical first cavities 111 and two horizontal second cavities 112 that are intersected with each other. In some other embodiments, the casting frame 110 may also be composed of other numbers of first cavities 111 and second cavities 112, which will not be described in detail here.

[0051] Figure 9 This is a structural schematic diagram of the prefabricated roof slab of the prefabricated column structure house provided in an embodiment of the present invention; Figure 10 This is a schematic diagram of the top support plate of the prefabricated column structure house provided in an embodiment of the present invention.

[0052] like Figure 9 and Figure 10 As shown, the prefabricated top plate 2 provided in this embodiment of the invention includes a top support plate 21, and multiple top support plates 21 can be sequentially spliced ​​to form a structure as shown in the figure. Figure 1 The "A"-shaped roof structure or the "I"-shaped (planar) roof structure shown can be assembled into a prefabricated roof slab 2 by splicing the top support plates 21. Then, the trusses are fixedly connected to the prefabricated roof slab 2 by welding or other methods, which can effectively improve the structural strength of the prefabricated roof slab 2. Existing connection methods such as welding and screws can be used between adjacent top support plates 21 and between the prefabricated roof slab 2 and the prefabricated wall panel 1, which will not be elaborated here.

[0053] In addition, such as Figure 9 and Figure 10 As shown, a top mounting surface 211 and a top bracket 212 are provided on the surface above the top support plate 21 (i.e., at the top during installation). The top bracket 212 is used to install decorative panels such as tiles and roof tiles on the mounting surface 211, which can improve the aesthetics of the house and enhance the house's resistance to sun and weathering.

[0054] Figure 11a and Figure 11bThis is a structural schematic diagram of the corner connector of the prefabricated column structure house provided in the embodiment of the present invention.

[0055] like Figure 11a and Figure 11b As shown, the corner connector 3 of the prefabricated column structure house provided in this embodiment of the invention includes a mesh frame 31. An outer corner wall panel 32 is provided on the two outer sides of the mesh frame 31 away from the prefabricated wall panel 1. The outer corner wall panel 32 can be used as an insulation board, decorative board, etc. The outer corner wall panel 32 is connected to the outer wall component 12 on the base 113, so that at the corner where the prefabricated wall panel 1 is spliced, the outer corner wall panel 32, the outer wall component 12 and the wall template frame 11 form a cavity formed by casting the mesh frame 31. This allows the mesh frame 31 at the corner to be cast as a whole with the adjacent wall template frame 11 when the prefabricated wall panel 1 is cast. The second structural rod 1121 of the prefabricated wall panel 1 adjacent to the corner connector 3 can extend horizontally into the interior of the perforated frame 31. Thus, when the perforated frame 31 and the casting cavity of the prefabricated wall panel 1 are cast as one unit, the second structural rod provides rigid support and connection, enhancing the connection strength between the corner connector and the prefabricated wall panel. Furthermore, in Figure 11b In the embodiment shown, the second structural rod 1121 does not extend out of the prefabricated wall panel 1. It is fixedly connected to the connecting bracket 114 of the prefabricated wall panel 1 by screws or other connectors in the mesh frame 31. This can also improve the connection strength between the corner connector and the prefabricated wall panel after casting.

[0056] The construction method of the prefabricated column structure house provided by the present invention is as follows: A wall template skeleton of corresponding dimensions is prepared according to the construction drawings; a first structural rod is placed in a first cavity, and a second structural rod is placed in a second cavity; the first structural rod and the second structural rod are connected; the wall template skeleton is installed on the load-bearing surface of the house; adjacent wall template skeletons are fixedly connected to form prefabricated wall panels through the connecting brackets of the second structural rods; the prefabricated wall panels are poured; and a prefabricated roof panel is installed on the poured prefabricated wall panels.

[0057] The construction drawings can be created according to the user's specific needs, including data such as the dimensions and locations of each room in the house. Based on this data, the wall template framework (i.e., the dimensions of the first and second cavities), floor slabs, corner connectors, etc., are set. According to the required door and window positions, corresponding clearance holes for the prefabricated wall panels are set, and the corresponding interior wall components and exterior wall components are prepared according to the size requirements of the prefabricated wall panels. Subsequently, the prepared basic materials can be transported to the designated construction site and assembled to form a prefabricated column structure house. After the house is poured, the construction of the basic structure of the house is completed. During this process, the only work required on the construction site is to assemble the modules and prepare and pour the concrete slurry on site, which can effectively shorten the construction period, simplify the construction process, and facilitate promotion and use.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
