Description

Technical Field

[0001] This application relates to the technical field of prefabricated buildings, and in particular to a light steel keel structure, panels, prefabricated buildings, and a panel preparation process. Background Technology

[0002] Light steel villas, also known as light steel structure buildings, are an important form of prefabricated buildings. Compared with traditional brick-concrete structures, light steel structures have advantages such as diverse appearances, beautiful shapes, good structural performance, high strength, good seismic resistance, thermal insulation, recyclable materials, strong plasticity, factory production of components, on-site assembly, high degree of standardization, fast assembly speed, and short construction cycle.

[0003] The basic material of light steel keel is galvanized or aluminum zinc coated steel strip, which is rolled into cold-formed thin-walled steel and connected with fasteners such as self-tapping screws and rivets to form components.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: because the connection is a point connection and stress is concentrated, both the keel and the fasteners bear a large shear force. Not only is the connection easy to be damaged when under stress, but the stability and stiffness of the entire component are also poor, which makes it easier for stress to concentrate at the connection and accelerate the damage to the connection. Therefore, the life of the entire light steel keel is relatively short. Summary of the Invention

[0005] To improve service life, this application provides a light steel keel structure, sheet metal, prefabricated building, and sheet metal preparation process.

[0006] Firstly, the light steel keel structure provided in this application adopts the following technical solution:

[0007] A light steel keel structure includes sheet-like components and a reinforcing layer. The sheet-like components include horizontal keels, vertical keels, and fasteners. The horizontal keels are provided at both ends of the vertical keels, and the horizontal keels are connected to the vertical keels by the fasteners. The reinforcing layer is provided on the horizontal keel at at least one end of the vertical keel, and the connection between the horizontal keel and the vertical keel connected by the fasteners is wrapped in the reinforcing layer.

[0008] By adopting the above technical solution, after the horizontal keel is connected to the vertical keel by fasteners, a reinforcement layer is cast on at least one end of the horizontal keel of the vertical keel to form a reinforcement layer. The cast reinforcement layer can wrap around the connection between the horizontal and vertical keels connected by fasteners, changing the point fixation of the connection between the horizontal and vertical keels to surface fixation and volume fixation, eliminating stress concentration, and increasing the mechanical strength and shear resistance of the connection by more than 2-3 times, and the stiffness of the light steel keel component by more than 2 times. Therefore, the reinforcement layer can improve the mechanical strength of the light steel keel and thus increase its service life. In addition, the reinforcement layer wraps around the connection between the horizontal and vertical keels, which can reduce the contact between the fasteners at the connection and air and water, reduce the oxidation and corrosion of the fasteners, and increase the service life of the fasteners.

[0009] Optionally, a reinforcing layer is provided on the peripheral sidewall of the sheet member, and the horizontal keels at both ends of the vertical keel are connected to the reinforcing layer; the reinforcement layer is also connected to the reinforcing layer; the reinforcement layer, the reinforcement layer, and the sheet member form a box-like structure with or without a lid.

[0010] By adopting the above technical solution, a reinforcing layer is cast on the peripheral wall of the sheet-like component, so that the reinforcing layer and the strengthening layer together wrap around the connection of the horizontal and vertical keels and the surrounding keels; the strengthening layer, the reinforcing layer and the sheet-like component will form a box-like structure with or without a cover, so that the entire structure is evenly stressed, avoids stress concentration, and greatly improves the mechanical strength of the light steel keel sheet-like component.

[0011] Optionally, a connecting mesh is provided on the horizontal keel wrapped by the reinforcing layer. The connecting mesh is located on the side of the horizontal keel away from the vertical keel, and the reinforcing layer also wraps the connecting mesh.

[0012] By adopting the above technical solution, the connecting mesh located within the reinforcement layer can reduce the strength of the reinforcement layer and reduce the phenomenon of cracking in the reinforcement layer; therefore, the connecting mesh can improve the reinforcement of the reinforcement layer.

[0013] Optionally, when the mesh size of the connecting mesh is relatively large, the connecting mesh and the reinforcing layer are provided on the horizontal keel at both ends of the vertical keel; when the mesh size of the connecting mesh is relatively small, the connecting mesh and the reinforcing layer are provided on the horizontal keel at either end of the vertical keel.

[0014] By adopting the above technical solution, when the mesh size is relatively large, the number of reinforcing bars in the connecting mesh per unit area will be relatively small. Therefore, placing connecting meshes at both ends of the vertical keel can better improve the reinforcement effect of the reinforcement layer. When the mesh size is relatively small, the number of reinforcing bars in the connecting mesh per unit area will be relatively large, because under the premise of saving resources, it is only necessary to place one connecting mesh at one end of the vertical keel.

[0015] Secondly, the plate material provided in this application adopts the following technical solution:

[0016] A type of board includes a structural panel, the structural panel including a light steel keel structure and an insulation layer, wherein a reinforcing layer is provided on a horizontal keel at one end of the vertical keel, and the reinforcing layer, two adjacent vertical keels and the horizontal keel away from the reinforcing layer all abut against the insulation layer.

[0017] By adopting the above technical solution, thermal insulation material is filled into the sheet-like components of the light steel keel structure, enabling the board to have thermal insulation function.

[0018] A type of board material includes a structural panel, the structural panel comprising a light steel keel structure and an insulation layer.

[0019] The reinforcing layer is provided on the horizontal keel at both ends of the vertical keel, and the reinforcing layer at both ends of the vertical keel and the two adjacent vertical keels all abut against the insulation layer.

[0020] By adopting the above technical solution, thermal insulation material is filled into the sheet-like components of the light steel keel structure, enabling the board to have thermal insulation function.

[0021] Optionally, a decorative layer is provided on the reinforcing layer at at least one end of the vertical keel, and the decorative layer is located on the side of the reinforcing layer away from the vertical keel.

[0022] By adopting the above technical solution and setting the decorative layer, the board can integrate heat preservation and decoration.

[0023] Thirdly, the prefabricated building provided in this application adopts the following technical solution:

[0024] A prefabricated building includes structural panels and connectors, wherein two adjacent structural panels are connected by the connectors.

[0025] By adopting the above technical solution, the size of the panels in the structural panel can be made so that one panel is used for each wall, and then the adjacent structural panels are connected with connectors. The panels can reduce problems such as cracking, leakage, falling off, and mold in the wall panels of the building. Therefore, the lifespan of the prefabricated building will be increased. Furthermore, transporting the panels to the site and assembling them into prefabricated buildings greatly improves the assembly rate and assembly speed of the building, and reduces the amount of on-site construction and construction time.

[0026] Fourthly, the preparation process of the sheet metal provided in this application adopts the following technical solution:

[0027] A process for preparing a sheet material includes the following steps: S1: Installing horizontal keels at both ends of a vertical keel using fasteners to form a sheet-like component, wherein the horizontal keels at both ends of the vertical keel are the upper and lower surfaces of the sheet-like component, respectively, and the other sidewalls of the sheet-like component are peripheral sidewalls; S2: Installing a connecting mesh on the lower surface of the sheet-like component; S3: Transferring the sheet-like component into a molding equipment, first casting a reinforcing layer on the lower surface of the sheet-like component, the reinforcing layer wrapping the connecting mesh, the horizontal keels near the connecting mesh, and the ends of the vertical keels near the connecting mesh; S4: Casting an insulation layer onto the reinforcing layer near the lower surface of the sheet-like component; S5: Fixing the connecting mesh on the upper surface of the sheet-like component, and casting a reinforcing layer on the upper surface of the sheet-like component that abuts against the insulation layer; S6: Casting a reinforcing layer on the peripheral sidewalls of the sheet-like component to form a sheet material; S7: Finally, removing the sheet material from the molding equipment.

[0028] By adopting the above technical solution, the molding equipment can define the sheet-like component, making it easier to cast the reinforcing layer and the insulation layer onto the sheet-like component; and the molding equipment can cast the reinforcing layer onto the sheet-like component after the reinforcing layer and the insulation layer have been cast.

[0029] Optionally, the molding equipment includes a mold, a support mechanism, and a casting and leveling mechanism. The mold includes a base block, a first limiting plate, a second limiting plate, a first connecting component, a second connecting component, and a limiting component. The support mechanism is disposed on the base block. The first limiting plate is disposed on the base block via the first connecting component, and two first limiting plates are provided. Each of the two first limiting plates is provided with a limiting component. The second limiting plate is provided at both ends of the first limiting plate, and the ends of the second limiting plate abut against the two first limiting plates. Multiple second limiting plates are provided, and adjacent two second limiting plates are connected together via the second connecting component. The second limiting plate closer to the base block is disposed on the base block via the second connecting component. The support mechanism is disposed on the base block and abuts against the connecting mesh on the lower surface of the sheet-like component. The casting and leveling mechanism is disposed on the second limiting plate away from the base block.

[0030] By adopting the above technical solution, the connecting mesh on the lower surface of the sheet-like component is placed on the support block of the base block. Then, the first limiting plate is connected to the base block using the first connecting assembly, and the two first limiting plates respectively abut against the vertical keels at opposite ends of the sheet-like component. Next, the second limiting plate abuts against the other two opposite sidewalls of the sheet-like component, and the second limiting plate is connected to the base block using the second connecting assembly. Then, a reinforcing layer is poured onto the sheet-like component between the first and second limiting plates using a pouring and leveling mechanism, and the end of the reinforcing layer away from the base block is leveled using the pouring and leveling mechanism. Next, an insulation layer is poured onto the end of the reinforcing layer away from the base block using a pouring and leveling mechanism, and the end of the insulation layer away from the base block is leveled using the pouring and leveling mechanism. Then, a mesh is connected to the horizontal keel at the end of the vertical keel away from the base block, and a reinforcing layer is poured onto the insulation layer through the connecting mesh away from the base block using a pouring and leveling mechanism, and the end of the reinforcing layer away from the base block is leveled using the pouring and leveling mechanism. Then, the first limiting plate and the second limiting plate are adjusted so that there is a certain distance between the first limiting plate and the second limiting plate and the sheet member. Then, the clamping component on the first limiting plate is clamped to the sheet member. Finally, a reinforcing layer is poured between the first limiting plate and the sheet member, and between the second limiting plate and the sheet member, to form a sheet.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The added reinforcement layer can improve the mechanical strength of the light steel keel and extend its service life;

[0033] 2. Using panel materials can improve the lifespan of prefabricated buildings. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0045] This application discloses a light steel keel structure.

[0046] Example 1

[0047] refer to Figure 1 and Figure 2 The light steel keel structure includes sheet-like components 11, on which a reinforcing layer 12, a connecting mesh 14, and a strengthening layer 13 are provided.

[0048] refer to Figure 1 The sheet-like component 11 includes a vertical keel 112, and a horizontal keel 111 is provided at both ends of the vertical keel 112. The horizontal keel 111 abuts against the vertical keel 112. Fasteners 113 are provided on the horizontal keel 111. The fasteners 113 can be self-tapping screws or rivets, etc.

[0049] refer to Figure 2A connecting mesh 14 is provided on the horizontal keel 111 at one end of the vertical keel 112. The connecting mesh 14 is connected to the side of the horizontal keel 111 away from the vertical keel 112 by one of the following methods: screwing, welding, fastening or bonding. The connecting mesh 14 is selected from steel plate mesh, steel wire mesh or steel bar mesh. The mesh size of the connecting mesh 14 is relatively small. The fastener 113 is located on the side of the connecting mesh 14 close to the horizontal keel 111.

[0050] Even when the mesh size of the connecting mesh 14 is small, the fastener 113 can also connect the connecting mesh 14, the horizontal keel 111, and the vertical keel 112 together.

[0051] refer to Figure 2 A reinforcing layer 12 is provided on the horizontal keel 111 with connecting mesh 14. The connecting mesh 14, fasteners 113, the horizontal keel 111 and the vertical keel 112 near the connecting mesh 14 are all wrapped in the reinforcing layer 12.

[0052] refer to Figure 2 In the sheet-like component 11, the horizontal keels 111 at both ends of the vertical keel 112 are the upper and lower surfaces of the sheet-like component 11, respectively, and the rest are the peripheral sidewalls of the sheet-like component 11. A reinforcing layer 13 is provided on the peripheral sidewalls of the sheet-like component 11. The vertical keel 112, the horizontal keels 111 at both ends of the vertical keel 112, and the reinforcing layer 12 are all connected to the reinforcing layer 13. The reinforcing layer 13, the reinforcing layer 12 at one end of the vertical keel 112, and the sheet-like component 11 form a lidless box shell mechanism.

[0053] In this embodiment, both the reinforcing layer 12 and the strengthening layer 13 are layer structures formed by cement mortar containing steel mesh or fiberglass mesh cast on the sheet member 11, and the thickness of the reinforcing layer 12 is preferably 10 mm.

[0054] The implementation principle of Embodiment 1 of this application is as follows: the horizontal keel 111 is brought into contact with the vertical keel 112, and then the horizontal keel 111 is fixed to the vertical keel 112 with fasteners 113 to form a sheet-like component 11.

[0055] Then the connecting net 14 is connected to the horizontal keel 111 at one end of the vertical keel 112, that is, the connecting net 14 is fixed on the upper or lower surface of the sheet member 11.

[0056] Next, the sheet-like component 11 is placed inside the molded equipment, with the connecting mesh 14 facing the bottom wall of the molded equipment. Then, cement mortar is poured into the molded equipment to form a reinforcing layer 12, which wraps around the connecting mesh 14, the horizontal joists 111 near the connecting mesh 14, the fasteners 113, and the end of the vertical joists 112 near the horizontal joists 111. Then, cement mortar is poured onto the peripheral sidewalls of the sheet-like component 11 to form a reinforcing layer 13, thereby forming an open-top box-like structure with the reinforcing layer 13, the reinforcing layer 12, and the sheet-like component 11.

[0057] Example 2

[0058] refer to Figure 3 The difference from Embodiment 1 is that a connecting mesh 14 is provided on the horizontal keel 111 at both ends of the vertical keel 112, and a reinforcing layer 12 is provided on the horizontal keel 111 at both ends of the vertical keel 112.

[0059] The reinforcing layers 12 at both ends of the vertical keel 112 are connected to the reinforcing layer 13, and the reinforcing layers 12 at both ends of the vertical keel 112 and the sheet-like components 11 form a covered box shell mechanism.

[0060] When connecting mesh 14 is provided on both ends of the horizontal keel 111 of the vertical keel 112, the size of the mesh of the connecting mesh 14 has no effect on the light steel keel structure 1; however, when the mesh of the connecting mesh 14 is relatively large, connecting mesh 14 must be provided on both ends of the horizontal keel 111 of the vertical keel 112; the fastener 113 can be located in the mesh of the connecting mesh 14.

[0061] The implementation principle of Embodiment 2 of this application is as follows: the horizontal keel 111 is brought into contact with the vertical keel 112, and then the horizontal keel 111 is fixed to the vertical keel 112 with fasteners 113 to form a sheet-like component 11.

[0062] Then, the connecting mesh 14 is fixed on the horizontal keel 111 at both ends of the vertical keel 112, that is, the connecting mesh 14 is fixed on the upper and lower surfaces of the sheet member 11.

[0063] Next, the sheet component 11 is placed inside the forming equipment, with the connecting mesh 14 on the lower surface of the sheet component 11 facing the bottom wall of the forming equipment. Then, cement mortar is poured into the forming equipment so that a reinforcing layer 12 is formed on both the lower and upper surfaces of the sheet component 11.

[0064] Finally, cement mortar is poured onto the periphery of the sheet member 11 to form a reinforcing layer 13, thereby forming a covered box structure by the reinforcing layer 13, the reinforcing layer 12 on the upper surface of the sheet member 11, the reinforcing layer 12 on the lower surface of the sheet member 11, and the sheet member 11.

There is a certain distance between the reinforcing layers 12 on the upper and lower surfaces of the sheet-like components 11. The reinforcing layers 12 on the upper and lower surfaces of the sheet-like components 11 and the two adjacent vertical keels 112 form a receiving cavity. The insulation layer 21 is located in the receiving cavity and abuts against the side wall of the receiving cavity. That is, the reinforcing layers 12 on the upper and lower surfaces of the sheet-like components 11 and the vertical keels 112 all abut against the insulation layer 21. In this embodiment, the insulation layer 21 is a layer structure formed by one of polystyrene particle insulation mortar, perlite insulation mortar or polyurethane foam slurry.

[0068] A decorative layer 22 is formed by applying paint or attaching decorative panels to the reinforcing layer 12 on the upper surface of the sheet member 11 or the reinforcing layer 12 on the lower surface of the sheet member 11.

[0069] In other embodiments, only one surface of the upper or lower surface of the sheet member 11 in the light steel keel structure 1 is provided with a reinforcing layer 12. In this case, the reinforcing layer 12, the horizontal keel 111 away from the reinforcing layer 12 and the two adjacent vertical keels 112 form a cavity for accommodating the insulation layer 21. The reinforcing layer 12, the horizontal keel 111 away from the reinforcing layer 12 and the two adjacent vertical keels 112 all abut against the insulation layer 21.

[0070] The implementation principle of the sheet material in this embodiment is as follows: the horizontal keel 111 is brought into contact with the vertical keel 112, and then the horizontal keel 111 is fixed to the vertical keel 112 with fasteners 113 to form a sheet-like component 11.

[0071] Then, a connecting mesh 14 is fixed on the lower surface of the sheet member 11; then, the sheet member 11 is placed inside the forming equipment, with the connecting mesh 14 on the lower surface of the sheet member 11 facing the bottom wall of the forming equipment, and then cement mortar is poured into the forming equipment to form a reinforcing layer 12 on the lower surface of the sheet member 11.

[0072] Then pour the insulation layer 21 onto the reinforcing layer 12 near the lower surface of the sheet member 11.

[0073] Then, a connecting mesh 14 is fixed on the upper surface of the sheet component 11, and then cement mortar is poured to form a reinforcing layer 12 on the upper surface of the sheet component 11 that is in contact with the insulation layer 21.

[0074] Finally, cement mortar is poured onto the periphery of the sheet member 11 to form a reinforcing layer 13, thereby forming a covered box structure by the reinforcing layer 13, the reinforcing layer 12 on the upper surface of the sheet member 11, the reinforcing layer 12 on the lower surface of the sheet member 11, and the sheet member 11.

[0075] If necessary, paint can be applied or decorative panels can be installed on the side of the reinforcing layer 12 on the upper surface of the sheet member 11 away from the reinforcing layer 12 on the lower surface of the sheet member 11 to form a decorative layer 22.

[0076] This application also discloses a prefabricated building.

[0077] Prefabricated buildings include structural panels 2 and connectors 3 that connect two adjacent structural panels 2. The connectors 3 can be anchors or screws as needed.

[0078] The implementation principle of prefabricated buildings in this application embodiment is as follows: the structural panel 2 is divided into wall panels, inner wall panels, floor panels and roof panels as needed, and then the wall panels, inner wall panels, floor panels and roof panels are transported to the construction site and connected with connectors 3 as needed.

After the position of the support block 61 is determined, the third bolt 66 is threaded through the third connecting plate 65 and connected to the support block 61.

[0095] refer to Figure 5 , Figure 8 and Figure 9 The second limiting plate 53 has a first groove 531. The second limiting plate 53, which is away from the bottom block 51, is provided with a casting and leveling mechanism 7. The casting and leveling mechanism 7 includes a first connecting block 71 that is slidably connected in the first groove 531. A fourth bolt is provided on the first connecting block 71 that passes through the first connecting block 71 and is threadedly connected to the second limiting plate 53. The first connecting block 71 has a first slot. A second connecting block 72 is engaged in the first slot. A third connecting block 73 is fixedly connected to the end of the second connecting block 72 that is away from the first connecting block 71.

[0096] The third connecting block 73 has a second sliding groove along its length, and a fourth connecting block 74 is slidably connected in the second sliding groove. The third connecting block 73 is provided with a moving component 75, which includes a screw 751 rotatably connected in the second sliding groove. The screw 751 passes through the fourth connecting block 74 and is threadedly connected to the fourth connecting block 74. A motor 752 is fixedly connected to the third connecting block 73, and the output shaft of the motor 752 is connected to the screw 751.

[0097] The fourth connecting block 74 has a second slot at the end away from the third connecting block 73. An installation block 76 is engaged in the second slot. There are multiple installation blocks 76, and different things are connected to each of the multiple installation blocks 76. One installation block 76 is fixedly connected to a scraper 77, and another installation block 76 is fixedly connected to a pouring pipe 78.

[0098] A guide ring 79 for the pouring pipe 78 to pass through is fixedly connected to the second connecting block 72. A winch 70 is provided at one end of the bottom block 51, and the connecting rope of the winch 70 is fixedly connected to the pouring pipe 78.

[0099] When it is necessary to pour the reinforcement layer 12 or the insulation layer 21, the mounting block 76 on the pouring pipe 78 is engaged with the second slot on the fourth connecting block 74, and then the second connecting block 72 on the third connecting block 73 is engaged with the first slot on the first connecting block 71, and the third connecting block 73 extends between two adjacent vertical keels 112, and the third connecting block 73 is located between two horizontal keels 111 at both ends of the vertical keel 112; then the fourth bolt passes through the first connecting block 71 and is threaded to the second limiting plate 53.

[0100] Then start the motor 752. The output shaft of the motor 752 drives the screw 751 to rotate. The screw 751 drives the fourth connecting block 74 to slide in the second groove of the third connecting block 73. The fourth connecting block 74 drives the mounting block 76 to move. The mounting block 76 drives the pouring pipe 78 to move, so that the pouring pipe 78 can better achieve pouring.

[0101] When the pouring pipe 78 moves, start the winch 70 to keep the pouring pipe 78 between the mounting block 76 and the guide ring 79 taut.

[0102] After the reinforcement layer 12 or insulation layer 21 is poured, the mounting block 76 on the scraper 77 is engaged with the second slot on the fourth connecting block 74. Then, the second connecting block 72 on the third connecting block 73 is engaged with the first slot on the first connecting block 71, and the third connecting block 73 extends between two adjacent vertical keels 112, with the third connecting block 73 located between two horizontal keels 111 at both ends of the vertical keel 112. Next, the fourth bolt passes through the first connecting block 71 and is threadedly connected to the second limiting plate 53. The motor 752 is started, and the output shaft of the motor 752 drives the screw 751 to rotate. The screw 751 drives the fourth connecting block 74 to slide in the second groove of the third connecting block 73. The fourth connecting block 74 drives the mounting block 76 to move, and the mounting block 76 drives the scraper 77 to move, thus leveling the reinforcement layer 12 or insulation layer 21.

[0103] The implementation principle of the sheet material preparation process in this application embodiment is as follows: first, the horizontal keel 111 is brought into contact with the vertical keel 112, and then the horizontal keel 111 is fixed to the vertical keel 112 with fasteners 113 to form a sheet-like component 11.

[0104] Then, a connecting mesh 14 is installed on the lower surface of the sheet member 11.

[0105] Next, the connecting mesh 14 on the lower surface of the sheet member 11 is brought into contact with the support block 61, so that there is a certain distance between the connecting mesh 14 on the lower surface of the sheet member 11 and the bottom block 51. Then, the first limiting plate 52 and the second limiting plate 53 are both brought into contact with the sheet member 11, and the second limiting plate 53, which is away from the bottom block 51, is located below the horizontal keel 111 on the upper surface of the sheet member 11.

[0106] Next, the pouring pipe 78 is extended between two adjacent vertical keels 112, and cement mortar is poured onto the horizontal keel 111 with the connecting mesh 14 to form a reinforcement layer 12 that wraps around the connecting mesh 14, the horizontal keel 111 near the bottom block 51, and the vertical keel 112 near the bottom block 51. Then, the end of the reinforcement layer 12 away from the bottom block 51 is smoothed with a scraper 77.

[0107] After the reinforcement layer 12 near the bottom block 51 has solidified, pour one of the following materials—polystyrene particle insulation mortar, perlite insulation mortar, or polyurethane foam slurry—towards the end of the reinforcement layer 12 away from the bottom block 51 using the pouring pipe 78 to form an insulation layer 21. The side of the insulation layer 21 away from the bottom block 51 is at a certain distance from the horizontal keel 111 away from the bottom block 51. Then, use a scraper 77 to smooth the insulation layer 21.

[0108] After the insulation layer 21 solidifies, a connecting mesh 14 is installed on the horizontal joists 111 away from the base block 51. Then, a second limiting plate 53 is superimposed on the first second limiting plate 53 away from the base block 51, with the last superimposed end of the second limiting plate 53 away from the base block 51 located above the horizontal joists 111 on the upper surface of the sheet member 11. Next, cement mortar is poured onto the connecting mesh 14 using the pouring pipe 78 to form a reinforcement layer 12 that wraps around the connecting mesh 14 away from the base block 51, the horizontal joists 111 away from the base block 51, and the vertical joists 112 away from the base block 51. The reinforcement layer 12 away from the base block 51 abuts against the insulation layer 21.

[0109] After the insulation layer 21, which is away from the bottom block 51, solidifies, the first limiting plate 52 and the second limiting plate 53 are moved so that there is a certain distance between the first limiting plate 52 and the sheet member 11 with two reinforcing layers 12. A clamping rod 563 is installed in the through hole of the first limiting plate 52, with one end of the clamping rod 563 abutting against the sheet member 11 and the other end abutting against the limiting block 562. There is also a certain distance between the second limiting plate 53 and the sheet member 11 with two reinforcing layers 12. Then, cement mortar is poured between the first limiting plate 52 and the sheet member 11, and between the second limiting plate 53 and the sheet member 11 to form a reinforcing layer 13, which abuts against the two reinforcing layers 12.

[0110] After the reinforcing layer 13 solidifies, the plate material is located between the first limiting plate 52 and the second limiting plate 53. Finally, the plate material can be removed from the bottom block 51.

[0111] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
