Description

[0001] This case is a divisional application filed on August 6, 2025, with application number 202511096655.8, entitled "A Ribbed Mold Panel Composite Wall, Concrete Module and Assembly Method Thereof". Technical Field

[0002] This invention relates to the field of prefabricated and modular building technology, and in particular to a ribbed formwork panel composite wall, a concrete module, and its assembly method. Background Technology

[0003] With the rapid development and widespread application of prefabricated and modular buildings, the level of industrialization and integration in the construction industry is constantly improving.

[0004] However, in existing prefabricated and modular building systems, during the pouring of concrete between double-sided composite walls, holes need to be made to tie the concrete formwork on both sides to prevent bulging. This affects interior decoration and requires the installation of tie rods, pouring concrete, dismantling tie rods, and sealing holes, making the construction process cumbersome and affecting construction efficiency. At the same time, in traditional double-sided composite walls, only one side of the formwork has embedded steel bars to participate in the load-bearing, which wastes the concrete material of the other side of the formwork.

[0005] Meanwhile, the exterior wall of the module needs to be sealed on-site to pour concrete, and after pouring the concrete, the formwork is dismantled and the exterior insulation and formwork are installed in sequence. This involves a lot of on-site work, is cumbersome, and affects the integration and construction efficiency.

[0006] During the assembly process, in order to connect the upper and lower modules, steel bars need to be inserted and tied on site, and the steel bars of the upper and lower modules need to be connected by sleeves. The amount of on-site tying and connection work is large and the operation is cumbersome, which affects the construction efficiency. Summary of the Invention

[0048] S5. Repeat steps S1-S4 to form the multi-layered concrete module building.

[0049] (III) Beneficial Effects

[0050] The ribbed molded plate composite wall of the present invention has the following beneficial effects:

[0051] To improve the rigidity of the first formwork shell: Ribs are set on the side walls of the first formwork shell, and one side of the reinforcing bar group is pre-embedded in the ribs. This is equivalent to increasing the thickness of the formwork shell at the connection of the reinforcing bar group, thereby improving the rigidity and lateral force resistance of the first formwork shell itself. As a result, when pouring concrete between the two first formwork shells, the first formwork shell is less likely to deform. This also reduces the number of tie bases and tie members used to improve the lateral force resistance of the first formwork shell, improving assembly efficiency and reducing material usage.

[0052] Improve the overall strength of the ribbed formwork composite wall: After grouting the grouting cavity, it is not necessary to remove the tie rods. The two first formwork shells and the concrete between them can be tied together as a whole, which improves the strength of the ribbed formwork composite wall and reduces the process of disassembling the tie rods, thus improving construction efficiency.

[0053] Reduced on-site construction work, simplified operation, and no impact on interior decoration: Both the first and second ribbed formwork panels are prefabricated integrated components in the factory. On-site construction only requires inserting the tie rods into the tie rod bases on the two ribbed formwork panels to achieve hole-free tie rod connection between the first and second ribbed formwork panels. This results in higher integration, eliminates the need for openings and does not affect the interior decoration of the formed building. It also reduces construction steps such as tie rod installation, concrete pouring, tie rod disassembly, and hole sealing, making the construction process more convenient and faster. At the same time, the pre-embedded steel bars on the relatively arranged first and second ribbed formwork panels can be staggered to form a steel reinforcement skeleton, eliminating the need for on-site steel bar insertion and tying, thus improving construction efficiency.

[0054] Reducing formwork thickness and saving concrete materials: By pre-embedding interlocking steel reinforcement groups on the first and second ribbed formwork plates, and cooperating with the concrete poured between the two first formwork plates, the two ribbed formwork plates can form a reinforced concrete structure that shares the load. There is no concrete part that does not participate in the load-bearing. While meeting the thickness standards of reinforced concrete for ribbed formwork plates in the construction field, the overall thickness of the ribbed formwork plate composite wall can be reduced without taking up additional interior space of the formed building, and concrete materials are also saved.

[0055] Meanwhile, the concrete module of this invention reduces on-site construction work: the third ribbed formwork panel is prefabricated in the factory as an integrated structure including the second formwork, an integrated insulation template, and a steel reinforcement frame. This eliminates the need for on-site installation of the insulation board, thus reducing the steps of sealing the formwork onto the pre-embedded steel reinforcement in the second formwork and pouring concrete between the formwork and the second formwork, as well as the installation steps of disassembling the formwork and then sequentially installing the insulation board and formwork, thereby improving construction efficiency.

[0056] Furthermore, the concrete module assembly method of this application can reduce on-site construction work and simplify operation. By protruding the vertical reinforcing bars embedded in the first ribbed formwork plate, the second ribbed formwork plate, and the third ribbed formwork plate upward and bending them inward to form an overlap, the overlap of the first layer module can overlap the reinforcing bar group and reinforcing bar skeleton of the second layer module, thereby realizing the connection between the upper and lower layers of modules. This reduces the construction steps of inserting and tying reinforcing bars on-site, as well as connecting the reinforcing bars of the upper and lower layers of modules through sleeves, simplifying operation and improving construction efficiency.

Detailed Implementation

[0077] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 4 The orientation is used as a reference.

[0078] Example 1

[0079] See Figure 2 , 4 -8. The ribbed mold plate composite wall proposed in this embodiment of the invention includes a first ribbed mold plate 1, a second ribbed mold plate 2, and a tie rod 32.

[0080] The first ribbed formwork plate 1 and the second ribbed formwork plate 2 include: a first formwork 31, ribs 33 and tie bases 34 arranged at intervals along the length of the sidewall of the first formwork 31, and a plurality of steel bar groups 35 pre-embedded in the ribs 33 on one side and arranged at intervals along the length of the first formwork 31. The cross-section of the tie base 34 is C-shaped.

[0081] The tie member 32 includes a support plate 321 and insert plates 322 fixed at both ends of the support plate 321. Both the support plate 321 and the insert plates 322 are vertically oriented.

[0082] When the two first mold shells 31 of the first ribbed mold shell plate 1 and the second ribbed mold shell plate 2 are arranged opposite each other, they can form a grouting cavity. The steel bars 35 on the two are arranged alternately along the length of the first mold shell 31, and the openings of the tie bases 34 on the two are opposite each other so that the two insert plates 322 of the tie members 32 can be inserted respectively. After concrete is poured into the grouting cavity between the two first mold shells 31, an integral ribbed mold shell plate composite wall can be formed.

[0083] The tie rod 32 is inserted into the tie base 34 on the two first mold shells 31, which enables the two mold shells 31 to resist lateral forces and prevents the two first mold shells 31 from deforming and separating when grout is poured between them. Among them, the rib 33, tie base 34 and steel bar group 35 are all pre-set / embedded in the first mold shell 31 in the factory, that is, the first ribbed mold shell plate 1 and the second ribbed mold shell plate 2 are both prefabricated integral components in the factory.

[0084] The ribbed formwork panel composite wall provided in this embodiment has the following beneficial effects:

[0085] To improve the rigidity of the first mold shell 31, ribs 33 are provided on the side wall of the first mold shell 31, and one side of the steel bar group 35 is pre-embedded in the ribs 33. This is equivalent to increasing the thickness of the mold shell at the connection of the steel bar group 35, thereby improving the rigidity and lateral force resistance of the first mold shell 31. As a result, when pouring concrete between the two first mold shells 31, the first mold shell 31 is less likely to deform. This also reduces the number of tie bases 34 and tie members 32 used to improve the lateral force resistance of the first mold shell 31, improving assembly efficiency and reducing material usage.

[0086] Improve the overall strength of the ribbed formwork composite wall: After grouting the injection cavity, it is not necessary to remove the tie rod 32. The two first formwork shells 31 and the concrete between them can be tied together as a whole, which improves the strength of the ribbed formwork composite wall and reduces the process of disassembling the tie rod 32, thus improving construction efficiency.

[0087] Reduced on-site construction work, simplified operation, and no impact on interior decoration: Both the first ribbed formwork plate 1 and the second ribbed formwork plate 2 are prefabricated integrated components in the factory. On-site construction only requires inserting the tie rods 32 into the tie rod bases 34 on the two ribbed formwork plates to achieve hole-free tie rod connection between the first ribbed formwork plate 1 and the second ribbed formwork plate 2. This results in higher integration, eliminates the need for openings and does not affect the interior decoration of the formed building. It also reduces construction steps such as tie rod installation, concrete pouring, tie rod disassembly, and hole sealing, making the construction process more convenient and faster. At the same time, the pre-embedded steel bars 35 on the relatively arranged first ribbed formwork plate 1 and the second ribbed formwork plate 2 can be staggered to form a steel reinforcement skeleton, eliminating the need for on-site steel bar insertion and tying, thus improving construction efficiency.

[0088] Reducing the thickness of the formwork and saving concrete materials: By pre-embedding interlocking steel reinforcement groups 35 on the first formwork 31 of the first ribbed formwork plate 1 and the second ribbed formwork plate 2, and cooperating with the concrete poured between the two first formwork 31, the two shear walls can form a reinforced concrete structure that shares the load. There is no concrete part that does not participate in the load-bearing. While meeting the thickness standards of reinforced concrete for shear walls in the construction field, the overall thickness of the ribbed formwork plate composite wall is reduced, without taking up additional indoor area of ​​the formed building, and concrete materials are also saved.

[0089] Specifically, the side wall of the pull base 34 is pre-embedded in the first mold shell 31.

[0090] Ribs 33 and steel bar groups 35 both extend along the height direction of the first mold shell 31 to vertically reinforce the first mold shell 31 and improve its rigidity and resistance to lateral deformation.

[0091] The reinforcing bar group 35 is perpendicular to the side wall of the first mold shell 31, so that the reinforcing bar groups 35 on the oppositely arranged first ribbed mold shell plate 1 and second ribbed mold shell plate 2 can be staggered along the length direction of the first mold shell 31.

[0092] See Figure 7 and 8 Furthermore, to facilitate the insertion of the tie rod 32, this ribbed mold plate composite wall also includes an operating rod 37.

[0093] The bottom of the pull base 34 is closed. The top of the insert plate 322 is fixedly provided with the connecting part 323. The bottom of the operating rod 37 can be sleeved or inserted onto the connecting part 323 and threadedly connected to the connecting part 323.

[0094] When installing the tie-down structure, the operator inserts the tie-down member 32 between the two first mold shells 31 by using the operating rod 37 threaded to the connecting part 323, and drives the two insert plates 322 of the tie-down member 32 to be inserted into the tie-down bases 34 on the two ribbed mold shell plates respectively, so as to assemble the tie-down member 32 and the tie-down base 34. Then, the operating rod 37 is rotated in the opposite direction to disengage the operating rod 37 from the connecting part 323.

[0095] The connecting part 323 is preferably a sleeve with internal threads.

[0096] Preferably, in order to improve tensile strength, this embodiment provides a plurality of tension bases 34, which are arranged in an array along the length and height directions of the first mold shell 31.

[0097] When the operator inserts the pull member 32 downward between the two first mold shells 31 by using the operating rod 37 threaded to the connecting part 323, the angle of the pull member 32 can be adjusted to avoid the pull base 34 above, so that the pull member 32 can be inserted into the pull base 34 from bottom to top.

[0098] Furthermore, the steel reinforcement group 35 includes a first vertical steel reinforcement 351, a plurality of first tie bars 352 and a second vertical steel reinforcement 353.

[0099] The first vertical reinforcing bar 351 is embedded in the first formwork shell 31. Multiple first tie bars 352 are arranged perpendicular to the sidewall of the first formwork shell 31 and spaced apart along the height direction of the first formwork shell 31. One end of each tie bar 352 is embedded in a rib 33 and tied to the first vertical reinforcing bar 351. The second vertical reinforcing bar 353 is tied to the other end of the first tie bar 352.

[0100] Therefore, the reinforcing bar group 35 is perpendicular to the side wall of the first formwork shell 31, and when the first formwork shell 31 of the first ribbed formwork shell plate 1 and the second ribbed formwork shell plate 2 are arranged opposite each other, the reinforcing bar group 35 on the two can be staggered along the length direction of the first formwork shell 31. At the same time, the first vertical reinforcing bar 351 and the second vertical reinforcing bar 353 in the reinforcing bar group 35 can serve as the vertical reinforcing bars of the ribbed formwork shell plate, and the first tie bar 352 can serve as the tie bar of the ribbed formwork shell plate. Furthermore, a plurality of horizontal bars are pre-embedded in the first formwork shell 31 at intervals along the height direction of the first formwork shell 31, and the plurality of horizontal bars and the plurality of first vertical reinforcing bars 351 are tied together to form a reinforcing mesh, which is pre-embedded in the first formwork shell 31 at the factory.

[0101] See Figure 4 , Figure 12 and Figure 13 Furthermore, the cross-sections of the first ribbed formwork plate 1 and the second ribbed formwork plate 2 are both L-shaped, and the cross-section of the combined ribbed formwork plate wall formed by the two is T-shaped. The long sides of the first ribbed formwork plate 1 and the second ribbed formwork plate 2 are located on the first side of module 100, and the short sides are located on the third side between the first side and the second side of module 100. The long side wall of the first formwork plate 31 is provided with ribs 33, tie bases 34 and steel bar groups 35, and the short side wall can form a cavity with a rectangular cross-section. This cavity is used to insert multiple third vertical steel bars 38 and to tie multiple third vertical steel bars 38 with second horizontal stirrups 39. The top of the third vertical steel bars 38 and the bottom of the third vertical steel bars 38 of the upper module 100 are respectively inserted and threaded to the two ends of the same sleeve to realize the vertical connection of the steel bars of the upper and lower modules 100.

[0102] The cross-section of the ribbed formwork composite wall is set to a T-shape so that the ribbed formwork composite wall has bidirectional lateral resistance in the direction of the long side and the short side extension, thereby giving the module 100 bidirectional lateral resistance in the length direction and the width direction.

[0103] Example 2

[0104] See Figure 1 , Figure 3 , Figure 9-11 Based on Embodiment 1, this embodiment also provides a concrete module, which includes the ribbed formwork panel composite wall in Embodiment 1, and also includes a third ribbed formwork panel 4.

[0105] The first side of module 100 is provided with a first ribbed mold shell plate 1 or a second ribbed mold shell plate 2, and the second side of module 100 opposite to the first side is provided with a first ribbed mold shell plate 1, a second ribbed mold shell plate 2 or a third ribbed mold shell plate 4.

[0106] The third ribbed formwork plate 4 includes: a second formwork 41 and an integrated insulation template 43 arranged opposite to each other, and a steel reinforcement cage 42 located between the second formwork 41 and the integrated insulation template 43. One side of the steel reinforcement cage 42 is embedded in the second formwork 41, and the other side is fixed to the integrated insulation template 43. The second formwork 41 and the integrated insulation template 43 enclose a grouting cavity.

[0107] See Figure 1 In a single-story concrete modular building, when there are two modules 100, a first ribbed formwork plate 1 and a second ribbed formwork plate 2 are respectively installed on the first side facing each other, and a third ribbed formwork plate 4 is installed on the second side facing away from each other. When there are more than two modules 100 in a single-story concrete modular building: the inner side of the two modules 100 at both ends is the first side, on which the first ribbed formwork plate 1 or the second ribbed formwork plate 2 is installed, and the outer side is the second side, on which the third ribbed formwork plate 4 is installed. The first side and the second side of the middle module 100 are respectively equipped with the first ribbed formwork plate 1 or the second ribbed formwork plate 2. When multiple modules 100 are assembled into a concrete modular building, the third ribbed formwork plate 4 forms the outer wall of the concrete modular building, and the first ribbed formwork plate 1 and the second ribbed formwork plate 2 form the inner wall of the concrete modular building.

[0108] Therefore, based on the above-mentioned structural configuration of the third ribbed formwork plate 4, it can be prefabricated in the factory as an integrated structure including the second formwork plate 41, the thermal insulation integrated formwork 43 and the steel reinforcement skeleton 42. The thermal insulation board does not need to be installed on site, which reduces the sealing process of encapsulating the formwork onto the second formwork plate with embedded steel reinforcement and pouring concrete between the formwork plate and the second formwork plate, as well as the installation process of disassembling the formwork and then installing the thermal insulation board and the formwork plate in sequence, thus improving construction efficiency.

[0109] Furthermore, to facilitate the vertical connection of the reinforcing bars of the upper and lower modules 100, this embodiment also includes the following settings:

[0110] See Figure 6 The second vertical steel bar 353 of the steel bar group 35 has its top portion extending beyond the top of the first formwork shell 31 bent inward and extended upward to form an overlap. The bottom of the second vertical steel bar 353 and the second vertical steel bar is flush with the first formwork shell 31, so that the second vertical steel bar 353 and the second vertical steel bar are evenly distributed along the height direction of the first formwork shell 31, thereby improving the strength of the first ribbed formwork shell plate 1 and the second ribbed formwork shell plate 2. The top of the rib 33 is flush with the top of the first formwork shell 31, and the bottom is higher than the bottom of the first formwork shell 31. The overlap on the lower ribbed formwork shell plate composite wall can avoid the bottom of the rib 33 on the upper ribbed formwork shell plate composite wall and overlap with the steel bar group 35 of the upper ribbed formwork shell plate composite wall to connect the upper and lower ribbed formwork shell plate composite walls, and thus connect the upper and lower modules 100.

[0111] See Figure 9-11 The vertical steel bars of the steel reinforcement skeleton 42 that extend beyond the top of the second formwork shell 41 are bent inward and extended upward to form an overlap. The overlap on the lower third ribbed formwork shell plate 4 can overlap the steel reinforcement skeleton 42 on the upper third ribbed formwork shell plate 4 to connect the upper and lower third ribbed formwork shell plates 4, and thus connect the upper and lower modules 100.

[0112] It should be noted that the first vertical steel bar 351 and the second vertical steel bar 353 of the steel bar group 35 are bent inward toward the center between the first ribbed formwork plate 1 and the second ribbed formwork plate 2. Similarly, the vertical steel bars of the steel bar skeleton 42 are bent inward toward the center between the second formwork plate 41 and the integrated insulation template 43. Based on these arrangements, when connecting the upper and lower modules 100, the overlapping portion of the lower module 100 can avoid and overlap the steel bars of the upper module 100.

[0113] In this embodiment, the steel bars of the upper and lower modules 100 are connected by the overlapping part of the lower module 100 with the steel bar group 35 or steel bar cage 42 of the upper module 100. This reduces the construction steps of installing sleeves on site to connect the steel bars of the upper and lower modules 100, as well as the construction steps of inserting and tying steel bars on site, which simplifies the operation and improves the construction efficiency.

[0114] Meanwhile, in this embodiment, the third ribbed formwork plate 4 of the upper and lower modules 100 is connected by overlapping, which can avoid on-site damage to the integrated insulation template 43 to form a space for sleeve operation or to install the integrated insulation template 43 on-site after the sleeve is installed, thus ensuring the integrity of the third ribbed formwork plate 4 and meeting the requirement that the third ribbed formwork plate 4 be prefabricated into an integrated structure by the factory.

[0115] See Figure 9 and Figure 10 Furthermore, the steel reinforcement cage 42 includes a steel mesh 421, multiple fourth vertical steel bars 422, multiple horizontal steel bars 423, multiple first horizontal stirrups 424, and multiple second tie bars 425.

[0116] See Figure 9 , Figure 10 and Figure 14 (The second tie bars 425, connected to both ends of the second formwork 41 along its length, are not fully shown.) The reinforcing mesh 421 is embedded within the second formwork 41 and extends along its length and height. Multiple fourth vertical reinforcing bars 422 are spaced apart along the length of the second formwork 41. Multiple horizontal reinforcing bars 423 extend along the length of the second formwork 41 and are spaced apart along its height, and are wrapped around and tied to the fourth vertical reinforcing bars 422, with their ends embedded within the second formwork 41 and tied to the reinforcing mesh 421. Multiple first horizontal stirrups 424 extend along the length of the second formwork 41 and are spaced apart along its height, and are wrapped around and tied to the fourth vertical reinforcing bars 422 at both ends of the second formwork 41 along its length. Multiple second tie bars 425 are perpendicular to the side wall of the second formwork 41. One end of the second tie bar 425 is pre-embedded in the second formwork 41 and tied to the fifth vertical bar 4211 of the steel mesh 421, and the other end is tied to the fourth vertical bar 422. The second tie bar 425 is used to tie the steel mesh 421 and the planar steel mesh formed by multiple fourth vertical bars 422, multiple horizontal bars 423 and multiple first horizontal stirrups 424 into a whole.

[0117] See Figure 9-11 It should be noted that the steel reinforcement cage 42 is prefabricated in the factory and embedded in the second formwork 41.

[0118] Among them, the portions of the fifth vertical steel bar 4211 and the fourth vertical steel bar 422 in the steel mesh 421 that extend out of the top of the second mold shell 41 are bent inward and extended upward to form an overlap.

[0119] See Figure 9 and Figure 10 Furthermore, in order to achieve the connection between the steel reinforcement frame 42 and the integrated insulation template 43, the steel reinforcement frame 42 in this embodiment also includes multiple truss bars 426.

[0120] One side of multiple truss bars 426 is pre-embedded in the second mold shell 41 and arranged at intervals along the length direction of the second mold shell 41. The truss bars 426 extend along the height direction of the second mold shell 41. Multiple nuts 427 are welded and fixed vertically at intervals on the side of the truss bars 426 away from the second mold shell 41.

[0121] The integrated thermal insulation template 43 has a connection hole 431 corresponding to the nut 427. A bolt 44 can be inserted into the connection hole 431 and connected to the nut 427 to fix the other side of the steel reinforcement skeleton 42 to the integrated thermal insulation template 43.

[0122] Therefore, based on the above structural configuration, one side of the steel reinforcement skeleton 42 can be pre-embedded in the second mold shell 41 in the factory, and the other side can be fixed on the integrated thermal insulation template 43 to form an integrated third ribbed mold shell plate 4.

[0123] Furthermore, the cross-section of the third ribbed formwork plate 4 is L-shaped. The long side of the third ribbed formwork plate 4 is located on the second side of module 100, and the short side is located on the third side between the first and second sides of module 100. The reinforcing steel skeleton 42 is evenly distributed on the sidewall of the second formwork 41.

[0124] The cross-section of the third ribbed mold plate 4 is set to an L-shape so that the third ribbed mold plate 4 has bidirectional lateral resistance in the long and short side extension directions, thereby giving the module 100 bidirectional lateral resistance in the length and width directions.

[0125] Furthermore, multiple modules 100 can be assembled into a concrete modular building. The on-site construction assembly method includes the following steps:

[0126] S1. Hoist the first layer module 100 and arrange the first ribbed mold shell plate 1 and the second ribbed mold shell plate 2 of the adjacent modules 100 relative to each other. Then insert the two insert plates 322 of the tie member 32 respectively so that the first ribbed mold shell plate 1 and the second ribbed mold shell plate 2 are connected by tie.

[0127] S2. Concrete is poured into the grouting cavity formed by the two first mold shells 31 of the first ribbed mold shell plate 1 and the second ribbed mold shell plate 2, as well as the second mold shell 41 and the integrated insulation template 43, to form the first layer of concrete module building.

[0128] S3. Hoist the second-layer module 100 onto the first-layer concrete modular building, and arrange the first ribbed formwork plate 1 and the second ribbed formwork plate 2 of the adjacent modules 100 of the second layer opposite each other. Then, insert the two insert plates 322 of the tie rod 32 respectively, so that the first ribbed formwork plate 1 and the second ribbed formwork plate 2 of the second layer form a ribbed formwork plate composite wall. At the same time, the lap joint of the first-layer steel reinforcement group 35 can be lapped onto the second-layer steel reinforcement group 35, and the lap joint of the first-layer steel reinforcement skeleton 42 can be lapped onto the second-layer steel reinforcement skeleton 42.

[0129] S4. Concrete is poured into the grouting cavity formed by the first ribbed formwork plate 1 and the second ribbed formwork plate 2 of the second layer, the two first formwork shells 31, the second formwork shell 41 and the integrated insulation template 43, to form the second layer concrete module building.

[0130] S5. Repeat steps S1-S4 to form a multi-layered concrete modular building.

[0131] The above-described assembly method of the concrete module based on this embodiment can reduce on-site construction work and simplify operation. By protruding the vertical steel bars pre-embedded in the first ribbed formwork plate 1, the second ribbed formwork plate 2, and the third ribbed formwork plate 3 upward and bending them inward to form an overlap, the overlap of the first layer module 100 can overlap the steel bar group 35 and the steel bar skeleton 42 of the second layer module 100, thereby realizing the connection between the upper and lower layers of modules 100. This reduces the construction steps of inserting and tying steel bars on-site, as well as connecting the steel bars of the upper and lower layers of modules 100 through sleeves, simplifying operation and improving construction efficiency.

[0132] Furthermore, step S1 also includes:

[0133] Multiple third vertical reinforcing bars 38 are inserted into the cavity formed by the short side walls of the first ribbed mold plate 1 and the second ribbed mold plate 2 and tied with second horizontal stirrups 39.

[0134] Step S3 also includes:

[0135] Multiple third vertical reinforcing bars 38 are inserted into the cavity formed by the short side walls of the first ribbed formwork plate 1 and the second ribbed formwork plate 2 of the second layer, and the third vertical reinforcing bars 38 are tied with the second horizontal stirrups 39. The top of the third vertical reinforcing bars of the first layer is connected to the bottom of the third vertical reinforcing bars 38 of the second layer through a threaded sleeve.
