Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a steel frame formwork structure and L-shaped wall formwork system suitable for L-shaped wall formwork. Background Technology

[0002] In construction engineering, concrete formwork is a crucial tool for ensuring structural dimensional accuracy and surface quality. While traditional loose-ply wooden formwork is relatively inexpensive, it suffers from low assembly and disassembly efficiency, poor reusability, and susceptibility to deformation, making it unsuitable for the demands of modern, high-efficiency construction. With technological advancements, steel-framed wooden formwork has gradually become one of the mainstream formwork systems. Steel-framed wooden formwork uses steel profiles as the frame and plywood panels as the panels, reinforced with steel ribs to enhance load-bearing capacity. It combines the rigidity of steel formwork with the lightweight nature of wooden formwork and is widely used in the construction of concrete structures such as walls and columns.

[0003] In actual engineering projects, wall structures are often not simply straight lines, but rather consist of numerous L-shaped walls. For such non-straight walls, traditional steel-framed wooden formwork is usually assembled on-site, combining multiple straight templates with additional connectors to form a corner shape. This method suffers from problems such as structural complexity, inconvenient adjustment, and poor structural stability. Utility Model Content

[0026] As described above, the steel frame formwork structure and L-shaped wall formwork system applicable to L-shaped wall formwork of this utility model have the following beneficial effects:

[0027] This utility model discloses a steel frame formwork structure suitable for L-shaped wall formwork. A wooden frame formwork is filled into one side of the frame structure to assemble the L-shaped wall formwork. Multiple frame structures are spliced ​​vertically and horizontally using clamping structures. Perpendicular frame structures are fixed using vertical connecting structures. Frame structures located at the inner corner of the L-shaped wall formwork are spliced ​​together using corner structures, and the vertical edges of the corner structures are fixed to the vertical edges of the frame structures located at the inner corner of the L-shaped wall formwork using clamping structures. This modular splicing method replaces the complex assembly process of existing steel frame wooden formwork construction that requires additional connectors. While ensuring structural strength and stability, it simplifies the connecting structure, reduces the weight of the overall formwork structure, eliminates the need for complex on-site assembly operations, effectively shortens construction time, and improves construction efficiency. Furthermore, this utility model, through the cooperation of the frame structure, corner structure, clamping structure, and vertical connecting structure, forms a stable whole, enabling the formwork to withstand greater pressure during concrete pouring, reducing the risk of deformation, ensuring the surface quality of the L-shaped wall structure, and improving the construction quality of the building project. Finally, the number and splicing method of the frame structure and corner structure can be flexibly adjusted according to different L-shaped wall size requirements, which can easily and quickly realize the adaptive adjustment of the formwork system and enhance the versatility and applicability of the formwork.

[0028] This utility model's L-shaped wall formwork system, including the inner corner wall formwork device, outer corner wall formwork device, and end wall formwork device, is assembled using a frame structure combined with a clamping structure, a corner structure, and a vertical connection structure. This reduces the number of specialized components, simplifies the structure, streamlines the construction process, and lowers the design, manufacturing, and maintenance costs of the mold. It also reduces the variety and quantity of components in inventory, improving resource utilization and effectively reducing production costs and inventory pressure. This modular assembly of the L-shaped wall formwork allows construction personnel to flexibly adjust the size and shape of the wall formwork according to actual project needs without redesigning the entire mold set. For example, in the pouring of L-shaped walls of different sizes, only the number of frame structures needs to be increased or decreased, and the assembly method adjusted, significantly improving construction flexibility. Furthermore, the modular assembly is easy to operate, with high installation and disassembly efficiency, shortening the construction cycle, improving construction efficiency, and adapting to the construction requirements of various building structures. Furthermore, by splicing the two sets of first wall formwork structures in the inner corner wall formwork device through corner structures, and by splicing the two sets of second wall formwork structures in the outer corner wall formwork device through vertical connection structures, as well as the vertical connection between the end wall formwork devices and the inner and outer corner wall formwork devices, the entire L-shaped wall formwork system forms a stable inner formwork space structure for casting the L-shaped wall. During the casting of the L-shaped wall, this stable inner formwork space structure can effectively resist the lateral pressure of the concrete, ensure the shape of the inner formwork space, and prevent wall formwork deformation, thereby ensuring the quality and precision of the cast wall and enhancing the stability and reliability of the structure. Finally, the support leg devices are hinged to the corresponding frame structures 1 in the first and second wall formwork structures, further enhancing the stability of the entire system and ensuring construction safety and wall quality.

[0029] This utility model discloses a steel frame template structure and L-shaped wall formwork system suitable for L-shaped wall formwork. By combining a frame structure with a clamping structure, a corner structure, and a vertical connection structure, L-shaped wall formwork of different thicknesses can be spliced ​​together. It has the advantages of simplified structure, convenient adjustment, strong applicability, strong flexibility, and strong stability. Attached Figure Description

[0089] like Figure 1-11 As shown, this utility model provides a steel frame formwork structure suitable for L-shaped wall formwork, comprising:

[0090] Frame structure 1, the frame structure 1 includes two horizontal borders 11 and two vertical borders 12, the frame structure 1 is a rectangular frame formed by the two horizontal borders 11 and the two vertical borders 12.

[0091] Frame wooden formwork 2, which fills one side of the frame structure 1 for assembling the L-shaped wall formwork;

[0092] The corner structure 3 includes two vertical corner frames 31 and four horizontal corner frames 32. The corner structure 3 is a corner frame formed by the two vertical corner frames 31 and the four horizontal corner frames 32. One end of each of the two horizontal corner frames 32 is connected to the two vertical corner frames 31, and the other end of each horizontal corner frame 32 is connected to the vertical corner frames 31. The corner structure 3 is connected to the frame structure 1 located at the corner inside the L-shaped wall formwork.

[0093] The gripper structure 4 is used to splice multiple frame structures 1 in the vertical and horizontal directions, and to splice the corner structure 3 with the frame structure 1 located at the corner inside the L-shaped wall formwork.

[0094] A vertical connection structure 5 is used to fix two mutually perpendicular frame structures 1 together.

[0095] This utility model discloses a steel frame formwork structure suitable for L-shaped wall formwork. The frame wooden formwork 2 is filled into one side of the frame structure 1 for assembling the L-shaped wall formwork. Multiple frame structures 1 are spliced ​​together in the vertical and horizontal directions by clamping structures 4. The mutually perpendicular frame structures 1 are fixed by vertical connecting structures 5. The frame structures 1 located at the inner corner of the L-shaped wall formwork are spliced ​​together by corner structures 3, and the vertical edge 31 of the corner structure 3 is fixed to the vertical edge 12 of the frame structure 1 located at the inner corner of the L-shaped wall formwork by the clamping structures 4. This modular splicing method replaces the complicated assembly process of the existing steel frame wooden formwork construction that requires additional connectors. Under the premise of ensuring structural strength and stability, it simplifies the connection structure, reduces the weight of the overall formwork structure, eliminates the need for complicated on-site assembly operations, effectively shortens the construction time, and improves construction efficiency. Furthermore, this utility model, through the cooperation of the frame structure 1, corner structure 3, clamping structure 4, and vertical connection structure 5, forms a stable whole, enabling the formwork to withstand greater pressure during concrete pouring, reducing the risk of deformation, ensuring the surface quality of the L-shaped wall structure, and improving the construction quality of the building project. Finally, the quantity and splicing method of the frame structure 1 and corner structure 3 can be flexibly adjusted according to different L-shaped wall size requirements, conveniently and quickly achieving adaptive adjustment of the formwork system, enhancing the versatility and applicability of the formwork.

[0096] Furthermore, the frame structure 1 and the corner structure 3 can be reused, reducing construction costs and meeting the requirements of green construction.

[0097] In this embodiment, as Figure 3-5 As shown in Figure 11, the frame structure 1 also includes pry point components 13 disposed at the four corners of the frame structure 1. The horizontal frame 11 and the vertical frame 12 are connected by the pry point components 13. The cross-sectional shape of the two ends of the pry point components 13 is adapted to the cross-sectional shape of the ends of the horizontal frame 11 and the vertical frame 12, which facilitates installation.

[0098] In this embodiment, as Figure 6 , 7 As shown, the gripper structure 4 includes a first gripping part 41, a second gripping part 42, and a pin 43 for connecting the first gripping part 41 and the second gripping part 42. The second gripping part 42 is provided with a limiting block 421, and the first gripping part 41 is provided with a limiting groove for accommodating the limiting block 421. The limiting block 421 is provided with continuous teeth 4211. The first gripping part 41 grips one of the frame structures 1, and the second gripping part 42 grips the other frame structure 1. The limiting block 421 on the second gripping part 42 is inserted into the limiting groove on the first gripping part 41, and the pin 43 is engaged in the slot formed by the teeth 4211 on the limiting block 421 to splice two adjacent frame structures 1.

[0099] In this embodiment, as Figure 5 , 8 As shown in Figures 10-11, the system also includes a bidirectional tie rod structure 6. The bidirectional tie rod structure 6 includes a first support base 61 and a locking tie rod 62 disposed on the first support base 61. The first support base 61 has a first pair of through holes. The vertical frame 12 has multiple second pairs of through holes 121. The frame wooden template 2 has a third pair of through holes corresponding to each of the second pairs of through holes 121. The locking tie rod 62 passes sequentially through the first pair of through holes, the second pair of through holes 121, and the third pair of through holes to connect two parallel frame structures 1. The second pair of through holes 121 on the vertical frame 12 are used to install the bidirectional tie rod structure 6. The locking tie rod 62 passes sequentially through the first pair of through holes, the second pair of through holes 121 on the vertical frame 12 of one frame structure 1, and the third pair of through holes on the frame wooden template 2, connecting to the vertical frame 12 of another frame structure 1 parallel to that frame structure 1, thus achieving a connection between two parallel frame structures 1. The locking tie rod 62 passes through the vertical frame 12 of the two parallel frame structures 1, and is fixed at both ends with fastening nuts. This ensures that the spacing between the two frame structures 1 conforms to the design thickness of the L-shaped wall. During installation, only the locking tie rod 62 needs to be inserted and the fastening nuts tightened, without the need for complex adjustments. During disassembly, the locking tie rod 62 and frame structure 1 can be quickly retrieved by loosening the fastening nuts, improving turnover efficiency. Since the lateral pressure generated during concrete pouring will push the formwork outward, the locking tie rod 62 transmits the pressure to the vertical frame 12 of the frame structure 1 through axial tension, thereby distributing it throughout the entire steel frame formwork structure. This prevents the wooden frame formwork 2 from bearing excessive load alone, significantly reducing the risk of deformation, cracking, or bulging, and extending its service life.

[0100] In this embodiment, as Figure 1-2As shown in Figure 11, it also includes a corner wooden template, which fills the corner structure 3. The corner vertical frame 31 is provided with a plurality of fourth pairs of pull holes 311, and the corner wooden template is provided with a fifth pair of pull holes corresponding to each of the fourth pairs of pull holes 311. The locking rod 62 passes through the first pair of pull holes, the fourth pair of pull holes 311, and the fifth pair of pull holes in sequence to connect the corner structure 3 to the frame structure 1 located at the outer corner of the L-shaped wall formwork. The fourth pair of through holes 311 on the vertical frame 31 at the corner is also used to install the bidirectional tie rod structure 6. The locking tie rod 62 passes through the first pair of through holes, the fourth pair of through holes 311, and the fifth pair of through holes in sequence and connects to the vertical frame 12 of the frame structure 1 located at the outer corner of the L-shaped wall formwork. This achieves synchronous fastening of the inner and outer formwork, effectively resisting the lateral pressure during concrete pouring, avoiding bulging or misalignment at the corner, ensuring the accuracy of the inner and outer corner dimensions of the L-shaped wall, and improving the quality of concrete forming. The corresponding through holes make the installation path of the locking tie rod 62 clear, eliminating the need for complex adjustments by workers and reducing assembly time.

[0101] In this embodiment, as Figure 3 , 10 As shown in Figure -11, the frame structure 1 also includes multiple positioning plates 14 disposed between the two horizontal frame sides 11. Each positioning plate 14 has multiple positioning through holes 141. By placing the vertical connecting structure 5 in the positioning through holes 141 at different positions on the positioning plates 14, the fixed position between the two mutually perpendicular frame structures 1 can be adjusted. The positioning through holes 141 on the positioning plates 14 are used to install the vertical connecting structure 5. The vertical connecting structure 5 passes through the positioning through holes 141 on the positioning plates 14 and connects to the vertical frame side 12 of another frame structure 1 to fix the two mutually perpendicular frame structures 1 together. Furthermore, by placing the vertical connecting structure 5 in the positioning through holes 141 at different positions on the positioning plates 14, the fixed position between the two mutually perpendicular frame structures 1 can be adjusted. This allows for adjustment of the distance between two other mutually parallel frame structures 1 that are perpendicularly connected to the frame structure 1, accommodating the rapid assembly of L-shaped wall formwork of different thicknesses and improving the versatility of the steel frame formwork structure.

[0102] In this embodiment, as Figure 10-11As shown, the vertical connection structure 5 includes a second support base 51 and a connecting rod 52 disposed on the second support base 51. The second support base 51 is provided with a first connecting through hole, and the frame wooden template 2 is provided with multiple second connecting through holes. The connecting rod 52 passes through the first connecting through hole, the positioning through hole 141, and the second connecting through hole in sequence and connects to the vertical frame 12 of another frame structure 1 to fix the two mutually perpendicular frame structures 1 together. The connecting rod 52 is used to fix the two mutually perpendicular frame structures 1, and by setting the connecting rod 52 in the positioning through holes 141 at different positions on the positioning plate 14, the fixed position between the two mutually perpendicular frame structures 1 can be adjusted, thereby adjusting the distance between two other mutually parallel frame structures 1 that are perpendicularly connected to the frame structure 1, so as to adapt to the assembly requirements of L-shaped wall templates of different thicknesses. No customized parts are required, and the same set of structures can match multiple wall thicknesses (such as 200mm, 300mm, etc.), reducing inventory costs, increasing template turnover rate, and meeting different construction scenarios. The connecting rod 52 only needs to be inserted into the corresponding connecting through hole and locked, which is simple to operate and simplifies the operation process.

[0103] In this embodiment, as Figure 1-2 As shown in Figures 5 and 11, the corner structure 3 also includes a middle frame 33 and a plurality of corner horizontal ribs 34 disposed between the two corner vertical frames 31. The other ends of the two corner horizontal frames 32 are connected through the middle frame 33. The corner horizontal ribs 34 are used to connect the corner vertical frames 31 and the middle frame 33.

[0104] In this embodiment, as Figure 3-5 As shown in Figures 1 and 11, the frame structure 1 also includes multiple frame horizontal ribs 15 and multiple frame vertical ribs 16. The frame horizontal ribs 15 are used to connect the two vertical frame edges 12, and the frame vertical ribs 16 are connected to the horizontal frame edges 11.

[0105] like Figure 5-11 As shown, this utility model also provides an L-shaped wall formwork system, comprising:

[0106] The wall formwork includes an inner corner wall formwork device 7, an outer corner wall formwork device 8, and two end wall formwork devices 9 that are perpendicularly connected to the inner corner wall formwork device 7 and the outer corner wall formwork device 8, respectively. Each of the inner corner wall formwork device 7, the outer corner wall formwork device 8, and the end wall formwork devices 9 includes a steel frame template structure suitable for L-shaped wall formwork as described above. The inner corner wall formwork device 7, the outer corner wall formwork device 8, and the end wall formwork devices 9 together enclose an inner formwork space for casting an L-shaped wall.

[0107] Multiple support leg devices 10, wherein the support leg devices 10 are respectively hinged to the inner corner wall formwork device 7 and the outer corner wall formwork device 8;

[0108] The inner corner wall formwork device 7 includes two sets of first wall formwork structures 71, which are spliced ​​together by a corner structure 3. The first wall formwork structure 71 is formed by splicing multiple frame structures 1 in the horizontal and vertical directions by a clamping structure 4. The frame structure 1 located at the inner corner of the L-shaped wall formwork in the two sets of first wall formwork structures 71 is spliced ​​together by the corner structure 3 to form the inner corner wall formwork device 7.

[0109] The outer corner wall formwork device 8 includes two sets of second wall formwork structures 81, which are spliced ​​together by a vertical connection structure 5. The second wall formwork structure 81 is formed by splicing multiple frame structures 1 in the horizontal and vertical directions by a clamping structure 4. The frame structure 1 located at the outer corner of the L-shaped wall formwork in the two sets of second wall formwork structures 81 is spliced ​​together by a vertical connection structure 5 to form the outer corner wall formwork device 8.

[0110] The end wall formwork device 9 is formed by splicing multiple frame structures 1 in the vertical direction through a clamping structure 4. The end wall formwork device 9 is vertically connected to the inner corner wall formwork device 7 and the outer corner wall formwork device 8 through a vertical connection structure 5.

[0111] Each of the support leg devices 10 is hinged to the corresponding frame structure 1 in the first wall formwork structure 71 and the second wall formwork structure 81.

[0112] This utility model's L-shaped wall formwork system comprises an inner corner wall formwork device 7, an outer corner wall formwork device 8, and an end wall formwork device 9, all assembled via a frame structure 1, a clamping structure 4, a corner structure 3, and a vertical connection structure 5. This reduces the number of specialized components, simplifies the structure, streamlines the construction process, and lowers the design, manufacturing, and maintenance costs of the mold. It also reduces the variety and quantity of components in inventory, improving resource utilization and effectively reducing production costs and inventory pressure. The modular assembly of the L-shaped wall formwork allows construction personnel to flexibly adjust the size and shape of the wall formwork according to actual project needs without redesigning the entire mold set. For example, in the pouring of L-shaped walls of different sizes, only the number of frame structures 1 needs to be increased or decreased, and the assembly method adjusted, significantly improving construction flexibility. Furthermore, the modular assembly is easy to operate, with high installation and disassembly efficiency, shortening the construction cycle, improving construction efficiency, and adapting to the construction requirements of various building structures. Furthermore, by splicing the two sets of first wall formwork structures 71 in the inner corner wall formwork device 7 through the corner structure 3, and splicing the two sets of second wall formwork structures 81 in the outer corner wall formwork device 8 through the vertical connection structure 5, as well as the vertical connection between the end wall formwork device 9 and the inner corner wall formwork device 7 and the outer corner wall formwork device 8, the entire L-shaped wall formwork system forms a stable inner formwork space structure for casting the L-shaped wall. During the casting of the L-shaped wall, this stable inner formwork space structure can effectively resist the lateral pressure of the concrete, ensure the shape of the inner formwork space, and avoid wall formwork deformation, thereby ensuring the quality and precision of the cast wall and enhancing the stability and reliability of the structure. Finally, the support leg device 10 is hinged to the corresponding frame structure 1 in the first wall formwork structure 71 and the second wall formwork structure 81, further enhancing the stability of the entire system and ensuring construction safety and wall quality.

[0113] In this embodiment, as Figure 5-6 As shown, multiple frame structures 1 in the horizontal direction are joined together by clamping the transverse ribs 15 of adjacent frame structures 1 using a gripper structure 4. Specifically, a first clamping part 41 clamps the transverse rib 15 of one frame structure 1, and a second clamping part 42 clamps the transverse rib 15 of another frame structure 1. A limiting block 421 on the second clamping part 42 is inserted into a limiting groove on the first clamping part 41, and a pin 43 engages in a slot formed by the teeth 4211 on the limiting block 421. Thus, multiple frame structures 1 are sequentially joined in the horizontal direction using multiple gripper structures 4. Figure 5 , 7As shown, multiple frame structures 1 in the vertical direction are spliced ​​together by clamping the horizontal frame edges 11 of two adjacent frame structures 1 by clamping claw structures 4. Specifically, the first clamping part 41 clamps the horizontal frame edge 11 of one frame structure 1, and the second clamping part 42 clamps the horizontal frame edge 11 of another frame structure 1. The limiting block 421 on the second clamping part 42 is inserted into the limiting groove on the first clamping part 41, and the pin 43 is engaged in the slot formed by the toothed pattern 4211 on the limiting block 421. In this way, multiple frame structures 1 are spliced ​​together in the vertical direction by multiple clamping claw structures 4 to form a first wall formwork structure 71, a second wall formwork structure 81, and an end wall formwork device 9, respectively.

[0114] In this embodiment, as Figure 5 , 11 As shown, the frame structure 1 located at the inner corner of the L-shaped wall formwork in the first wall formwork structure 71 is spliced ​​together by the corner structure 3 to form the inner corner wall formwork device 7. In the first wall formwork structure 71, the frame structure 1 and the corner structure 3 located at the inner corner of the L-shaped wall formwork are spliced ​​together by the clamping structure 4. The first clamping part 41 clamps the frame horizontal rib 15 of the frame structure 1 located at the inner corner of the L-shaped wall formwork, and the second clamping part 42 clamps the corner horizontal rib 34 of the corner structure 3. The limiting block 421 on the second clamping part 42 is inserted into the limiting groove on the first clamping part 41, and the pin 43 is engaged in the slot formed by the toothed pattern 4211 on the limiting block 421. By clamping the frame horizontal rib 15 and the corner horizontal rib 34, the corner vertical frame 31 of the corner structure 3 and the vertical frame 12 of the frame structure 1 located at the inner corner of the L-shaped wall formwork are fixed to each other, so that the frame structure 1 located at the inner corner of the L-shaped wall formwork in the first wall formwork structure 71 is spliced ​​together by the corner structure 3.

[0115] In this embodiment, the corner structures 3 in the horizontal and vertical directions can also be spliced ​​together by the gripper structures 4. The splicing method is similar to that described above and will not be repeated here.

[0116] In this embodiment, as Figure 5 , 10 As shown in -11, the frame structure 1 located at the outer corner of the L-shaped wall formwork in the second wall formwork structure 81 is spliced ​​together by the vertical connection structure 5. The connecting rod 52 passes through the positioning through hole 141 on the positioning plate 14 of the frame structure 1 located on one side of the outer corner of the L-shaped wall formwork and connects to the vertical frame 12 of the frame structure 1 located on the other side of the outer corner of the L-shaped wall formwork, so as to splice the frame structure 1 located at the outer corner of the L-shaped wall formwork to form the outer corner wall formwork device 8.

[0117] In this embodiment, as Figure 5 , 10As shown in Figure -11, the connecting rod 52 passes through the positioning through holes 141 at different positions on the positioning plate 14 of the frame structure 1 in the end wall formwork device 9 and connects to the vertical frame 12 of the frame structure 1 in the first wall formwork structure 71 and the second wall formwork structure 81, respectively. This connects the end wall formwork device 9 vertically to the inner corner wall formwork device 7 and the outer corner wall formwork device 8, respectively, so that the inner corner wall formwork device 7, the outer corner wall formwork device 8, and the end wall formwork device 9 together enclose the inner formwork space for casting the L-shaped wall. Furthermore, by setting the connecting rod 52 in the positioning through holes 141 at different positions on the positioning plate 14, the distance between the first wall formwork structure 71 and the second wall formwork structure 81 can be adjusted, thereby flexibly changing the size of the inner formwork space to accommodate the casting of walls of different thicknesses.

[0118] In this embodiment, as Figure 5 , 10 As shown in Figure -11, the bidirectional tie rod structure 6 connects the vertical frame 12 of the parallel frame structure 1 in the first wall formwork structure 71 and the second wall formwork structure 81. The locking tie rod 62 passes through the first pair of through holes, the second pair of through holes 121 on the vertical frame 12 of one frame structure 1, the third pair of through holes on the frame wooden template 2, and the vertical frame 12 of another frame structure 1 parallel to the frame structure 1. The locking tie rod 62 also passes through the first pair of through holes, the fourth pair of through holes 311 on the corner vertical frame 31, and the fifth pair of through holes on the corner wooden template. The through hole is connected to the vertical frame 12 of the frame structure 1 located at the outer corner of the L-shaped wall formwork, so as to connect the vertical frame 12 of the frame structure 1 that are set in parallel in the first wall formwork structure 71 and the second wall formwork structure 81 in sequence. The two ends are fixed with fastening nuts to ensure that the distance between the two first wall formwork structures 71 and the second wall formwork structure 81 meets the design thickness of the wall. This realizes the synchronous fastening of the inner and outer formwork, effectively resists the lateral pressure during concrete pouring, avoids bulging or misalignment at the corner, ensures the accuracy of the inner and outer corner dimensions of the L-shaped wall, and improves the quality of concrete forming.

[0119] In this embodiment, as Figure 5As shown, the support leg device 10 includes two support rods 101 hinged together. One end of each support rod 101 is hinged to the other, and the other end is hinged to the corresponding vertical frame structure 1. Thus, the two support rods 101 combined with the frame structure 1 form a stable triangular support structure. During concrete pouring, this structure effectively resists the lateral pressure of the concrete and external forces generated during construction, preventing the L-shaped wall formwork system from tilting or deforming, ensuring the stability of the L-shaped wall formwork system during construction, and guaranteeing the quality of the wall pouring and construction safety. Furthermore, because the two support rods 101 are hinged together, the angle between them can be flexibly adjusted according to actual construction needs. This allows for adjustment of the support strength and position under different construction environments and L-shaped wall pouring requirements, ensuring the L-shaped wall formwork system is always in a good supported state, improving the flexibility and adaptability of construction.

[0120] In this embodiment, as Figure 5 , 9 As shown, the support leg device 10 further includes a first fixed seat 102 and a second fixed seat 103. One end of each of the two support rods 101 is hinged to the other through the first fixed seat 102, and the other ends of each of the two support rods 101 are respectively hinged to the corresponding frame structure 1 in the vertical direction through the second fixed seat 103. The other ends of each of the two support rods 101 are respectively hinged to the corresponding frame structure 1 in the vertical direction of the first wall formwork structure 71 and the second wall formwork structure 81 through the second fixed seat 103. The second fixed seat 103 is provided on the frame transverse rib 15, and the other end of the support rod 101 is hinged to the second fixed seat 103. The second fixed seat 103 is provided with a first fixed through hole 1031, and the frame transverse rib 15 is provided with a second fixed through hole 151 corresponding to the first fixed through hole 1031. The second fixed seat 103 is provided on the frame transverse rib 15 by passing a fixing bolt through the first fixed through hole 1031 and the second fixed through hole 151 in sequence. The frame cross rib 15 has multiple second fixing through holes 151 for installing the outrigger device 10. The installation position of the outrigger device 10 can be adjusted by setting the outrigger device 10 on the second fixing through holes 151 at different positions on the frame cross rib 15.

[0121] In this embodiment, as Figure 5As shown, the support rod 101 includes an upper sleeve 1011, a middle sleeve 1012, and a lower sleeve 1013. One end of the upper sleeve 1011 is inserted into one end of the middle sleeve 1012, and the other end of the upper sleeve 1011 is hinged to the corresponding frame structure 1 in the vertical direction. One end of each of the two lower sleeves 1013 is hinged to each other, and the other ends of each of the two lower sleeves 1013 are respectively inserted into the other end of the corresponding middle sleeve 1012. The other ends of the two upper sleeves 1011 are respectively hinged to the corresponding frame structure 1 in the vertical direction of the first wall formwork structure 71 and the second wall formwork structure 81 through the second fixing seat 103. One end of each of the two lower sleeves 1013 is hinged to each other through the first fixing seat 102.

[0122] In summary, the steel frame formwork structure and L-shaped wall formwork system of this utility model have the following advantages:

[0123] (1) Simplified structure and reduced cost: The inner corner wall formwork device 7, the outer corner wall formwork device 8, and the end wall formwork device 9 all adopt steel frame formwork structure splicing, reducing special connecting parts, simplifying the structure, simplifying the construction process, and reducing the design, manufacturing and maintenance costs of the mold. At the same time, the frame structure 1 and the corner structure 3 can be reused, reducing the types and quantities of parts in stock, improving resource utilization, effectively reducing production costs and inventory pressure, and also meeting the requirements of green construction.

[0124] (2) Convenient adjustment and enhanced applicability: The number of each structure and splicing method can be flexibly adjusted according to the different L-shaped wall size requirements, which can conveniently and quickly realize the adaptability adjustment of the template system, adapt to the construction requirements of various building structures, and enhance the versatility and applicability of the template.

[0125] (3) High flexibility: By setting the vertical connection structure 5 in the positioning through holes 141 at different positions on the positioning plate 14, the distance between the first wall mold structure 71 and the second wall mold structure 81 can be adjusted, thereby flexibly changing the size of the inner mold space to adapt to the rapid assembly of L-shaped wall molds of different thicknesses.

[0126] (4) Improve construction efficiency: The modular splicing method is adopted. Multiple frame structures 1 are spliced ​​together through the clamp structure 4 and the vertical connection structure 5. The frame structure 1 located at the corner of the L-shaped wall formwork is spliced ​​together through the corner structure 3, which replaces the complicated additional connection assembly process. Construction personnel can flexibly adjust the size and shape of the L-shaped wall formwork as needed. For example, when pouring L-shaped walls of different sizes, it is only necessary to add or remove the frame structure 1, the corner structure 3 and adjust the splicing method. There is no need to redesign the mold. The installation and disassembly are simple, which greatly shortens the construction cycle and significantly improves the construction efficiency.

[0127] (5) Strong stability, ensuring construction quality: The inner corner wall formwork device 7 is spliced ​​together by the corner structure 3, and the outer corner wall formwork device 8 is spliced ​​together by the vertical connection structure 5. The end wall formwork device 9 is vertically connected to the inner corner wall formwork device 7 and the outer corner wall formwork device 8, forming a stable inner formwork space structure. During concrete pouring, it can effectively resist lateral pressure, ensure the shape of the inner formwork space, and avoid wall formwork deformation. In addition, the support leg device 10 is hinged to the corresponding frame structure 1 in the first wall formwork structure 71 and the second wall formwork structure 81, further enhancing the system stability, ensuring construction safety and wall quality, and improving the overall construction quality of the building project.
